Message from the CEO Miguel Stilwell d’Andrade CEO of EDP and EDP Renewables Dear Shareholders and Stakeholders, In 2023, the global energy landscape continued its transformative journey. Governments and businesses prioritized investments in clean energy and energy efficiency to address climate change and energy security concerns. At COP28, nations made a historic pledge to transition energy systems away from fossil fuels, highlighted by the advocacy, supported by EDP, for tripling global renewable energy capacity by 2030. Yet, carbon emissions continued to increase and 2023 will likely be the hottest year on record. Inflationary pressures, supply chain restrictions, and geopolitical tensions distressed energy markets and affected investment decisions, highlighting the importance of resil- ience and diversification. Permitting and lack of grid connections hindered the development of renewable projects. At EDP, we remained focused in transitioning to a clean energy era, continuously finding ways to navigate the uncertain context and address the various challenges. That is why in our 2023-2026 Business Plan, announced in March 2023, we have committed a further 25 billion euros of global investment to boost renewables generation, reinforcing our electricity networks, and supporting our clients towards decarbonization, across our regional hubs. We are proud to be one of the greenest utilities in the world, with more than 85% of our capacity generated from renewable energy. We want to take it further by going carbon free by 2025, all-green by 2030, and net-zero by 2040. Last year alone we took significant steps in that direction: EDP was ranked as the most sus- tainable electric utility in the world by S&P Global CSA for the third time in a decade. And the company was acknowledged as a leader in climate action during the United Nations Climate Ambition Summit in New York due to the credibility of its decarbonization and sus- tainability strategies, particularly its Climate Transition Plan. We are reimagining the energy sector and driving a massive acceleration of renewables to meet the urgent need for cleaner, more reliable, and more affordable energy for all. 010 Integrated Annual Report 2023 Message from the CEO Part I 

Renewables generation We have added 2.5 GW of renewables installed capacity in 2023, ending the year with a total of 24.4 GW and 4.4 GW under construction. In Europe, we have commissioned the first hybrid projects in Portugal and Spain, combining wind and solar power generation in one single grid connection. We launched Europe’s larg- est solar project, located in Poland. We secured our first stand-alone battery sto rage proj- ect, in the United Kingdom. We continued to grow in North America, having commissioned 1.2 GWs of utility scale projects in 2023, and expanded our Distributed Generation footprint in the region to a total capacity of 246 MW. And we have launched our largest wind on- shore complex globally in Brazil, with 138 wind turbines. In the Asia-Pacific region, we already reached an installed solar capacity of more than 1 GWp. Ocean Winds, our 50/50 joint venture with ENGIE focused on offshore wind energy, holds now a secured portfolio of projects in 7 countries representing 16.6 GW of gross ca- pacity, of which 1.5 GW is in operation, 1.9 GW under construction and 13.2 GW under advanced development. We are on track to hit our target of being coal free by 2025, following the sale of the Pecém coal power plant in Brazil, and the steps taken towards the conversion of the Aboño II ther- mal plant in Spain from coal into gas, as well as the authorization for the closure of EDP’s last remaining coal plants in the country (Soto de Ribera and Los Barrios). We remain fully com- mitted to our Just Transition plans to turn our former thermal sites into green hubs, with am- bitious projects being developed along four business streams: green hydrogen, renewables, storage, and flexibility. We have also kept a focused investment strategy in our hydro power plants in Portugal, Spain and Brazil, fostering hybridization and pumping solutions, aiming at operational ex- cellence while managing volatility. Electric networks Networks are the backbone of the energy transition, and we are proud to take good care of the ones that we manage. In 2023 we operated a Remunerated Asset Based of 7.6 billion euros, spread across 387 thousand km of distribution and transmission grids, distributing 86 TWh of energy in Brazil, Portugal, and Spain. And our quality of service has been widely recognized in the sector. We have invested more than 975 million euros in expanding and modernizing our networks, making our portfolio more reliable, resilient and digital. We have already installed 7.6 million smart meters (+1.1 million year-on-year) which allowed us to have 82% of our distributed energy remotely metered. Client solutions Distributed solar generation has become one of EDP's fastest growing business segments - it should account for around 50% of all new solar additions globally over the next few years. We have now distributed solar generation across 16 markets worldwide, with around 1.7 GWp of cumulative capacity installed for residential customers and businesses. Up to date, our teams have implemented 140,000 installations in residential homes in Europe, in addi- tion to small businesses and large companies in other key markets. With regards to electric mobility, EDP in Iberia continues its consolidation in this field with 4,700 new public chargers as of year-end. By 2026, the goal is to reach 7,000 public charging points. Energy management Important steps were taken in implementing a Global Energy Management platform at EDP, bringing closer together the integrated value from asset development to customer supply to maximize the value of our integrated portfolio and margin. Energy management has increasingly been an instrument of competitiveness for our growth plan, enabling investments by bridging intermittent renewable energy sources with sophis- ticated clients that demand clean, affordable, and reliable energy. Our people, organization and social footprint around the world As we push forward with our ambitious goals, we are continuously refining our operating model to reflect our global presence and operational excellence in a volatile business land- scape, starring our in-house talent. We are more than 13,000 people – more than 60 nation- alities across the world – embracing a purpose-driven career, where empowerment, trans- parency, respect, and meaningful work are key goals. This is reinforced by our recognition as a Top Employer in many of the regions EDP operates. And for the third year running, EDP was also included in the Bloomberg Gender Equality Index, which reflects our commitment to creating a more diverse and inclusive workplace. 011 Part I Integrated Annual Report 2023 Message from the CEO 

We continue betting on digital transformation, democratizing access to data and artificial intelligence, designing a global strategy with GenAI at the core. And we have been taking research and development investment seriously, accelerating delivery in 7 innovation domains – renewables, grids, distributed generation, storage & flexibility, hydrogen, mobility, and decarbonization of end uses – through internal incubation, open innovation & partnerships, and corporate venture capital. Our goal is also to lead a just energy transition fostered by our social impact strategy. Through our Foundations in Portugal, Spain, and Brazil, we have strengthened projects reaching out communities in need. EDP Energia Solidária is a good example - a 2 million euros commitment to back social projects in these regions focused on promoting electric mobility, solar energy, and energy efficiency initiatives. In 2023 we have also launched the 5 th edition of the Access to Energy Fund that, over its last four editions, dedicated a total investment of 2.5 million euros to support projects in Africa, benefiting more than 1.5 million people, and impacting key areas such as health, agriculture, education, and access to drinking water. We continued to carry out our daily operations with strict compliance with the laws and regulations governing the regions in which we operate and ensuring the highest standards of ethics and integrity. This strong ethical foundation - that stands today as a cornerstone of our organization's reputation – enabled us to be recognized by the Ethisphere Institute for the 12 th consecutive year as one of the world's most ethical companies. Our financial performance The 2023-2026 Business Plan restated the company profile of strong value creation with a sound balance sheet and low risk profile, supported by our diversified shareholder base and high-quality long-term investors. When announcing the new Business Plan last March, we have successfully executed a 1 billion euros capital increase at EDP Renewables level to partially finance the company’s growth plan, and a 1 billion euros capital increase at EDP level to fund the takeover o˜er of our subsidiary in Brazil. The transaction was successfully concluded, simplifying the group's structure and giving greater flexibility t o m anage o ur presence in the Brazilian market. In 2023, EDP has delivered outstanding results, with a recurring EBITDA of 5,023 million euros, representing an 11% increase year-on-year, benefiting from a strong performance of Iberian integrated electricity margin, a strong execution of the asset rotation program and a stability of the networks business. Recurring Net Profit reached a record of 1,290 million euros, driven by EBITDA growth and the buyback of minorities in our Brazilian business, despite lower wind resource and load factors. We have successfully issued 7.3 billion euros in green bonds in the 2021-2023 period, while achieving BBB rating across 3 top agencies. And EDP has revised its dividend policy to a more sustainable payout ratio in line with peers, ensuring a solid and sustainable dividend policy, raising the floor to €0.20 by 2026. Looking back with appreciation EDP has a world class team and everyone has played a part in making 2023 another successful year. I want to thank my colleagues on the Executive Board of Directors for their tireless work and dedication over the 2021-2023 mandate and knowing I could always count on them. I also want to thank and recognize João Talone, the Chairman of EDP’s General and Su- pervisory Board, for his strong convictions, continued support and wisdom over this very successful term. I have learnt a lot from João Talone over this period. Finally, a word of ap- preciation to all the members of the General and Supervisory Board for their valuable con- tributions and insights. I also have heartfelt gratitude to our stakeholders who continued to support EDP – our shareholders, customers, suppliers, regulators, partners, and local communities. And a spe- cial word goes out to EDP’s 13,000 colleagues around the globe who make our business, our impact, and everything we achieved this year possible. As I look to 2024, I believe EDP is well placed to continue leading the energy transition, driving positive change on a global scale and creating value for all stakeholders.

For more information see www.edp.com Stakeholder management Stakeholder management is a strategic priority for EDP, following the ESG (Environment; Social; Governance) growing importance in the business world. Engaging with stakeholders is an extremely demanding exercise for companies, that involves sharing information and being transparent in their relationship with society and, in particular, with all who are affected by their activities. EDP seeks to achieve this through four major interaction commitments: comprehend, communicate, trust, and collaborate. EDP remains commied to preserving the excellence achieved in this area, constantly seeking to listen to its key stakeholders, adapt- ing and improving its procedures, and incorporating different visions into its action plans. As a result, in 2023, the EDP Group carried out a global and integrated study among several stakeholder segments in the regions where it operates, with more than 6,000 respondents. This exercise allowed EDP to assess stakeholders' global perception of the company and its role in leading the energy transition. Following the first global assessment conducted in 2021, there has been steady progress in perceptions and strong reinforcement of our global positioning. EDP Group continues commied to achieving an excellent level regarding stakeholder engagement activities, designing new procedures, and global and unified approaches on its main mar- kets, adapting it whenever necessary regarding cultural and social specificities. EDP strongly believes this activity is key to enabling the implemen- tation of the business plan, improving business success, anticipating risks, and also to create value for the stakeholders involved. Position EDP as a global company at the forefront of the energy tran- sition, increasing awareness in our key markets, and establishing long-lasting and trustful relations with our main stakeholders will continue to be our main purpose.

025 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment 2.1. Business Environment 2.1.1. General context 2023 overview 2023 was marked by efforts to recover from what happened in the previous years. After a global pandemic and the immediate effects of the war in Ukraine, the impacts on the global economy still last. The different global economies still struggle to get back on track and the energy sector is finding its way back to lower volatility. While in 2022 inflation rates were at very high levels, 2023 was the year to start seeing more stable indexes. In the Eurozone inflation was 5.4% by 2023, a drop from 8.4% in 2022, while in the United States, it stood at 4.1% against 8.0% in 2022 (source: Focus Economics). Monetary policy measures played a big role in 2023, with consecutive increases in interest rates both by the European Central Bank and by the US Federal Reserve. The higher cost of capital creates a challenging environment for investors, cautiously considering where to put their money next. In 2023 the energy sector recovered from the environment of uncertainty and high volatility from 2022. Coal annual average prices decreased more than 55% in 2023, as API#2 – a widely used European price reference for coal – was around 129 $/ton compared to 290 $/ton in 2022. The Brent price was somewhat stable during the first half of 2023 but following cuts in Saudi Arabia, Russia, and OPEC+ countries production, it reached the maximum of 95.4 dollars per barrel ($/bbl) by September. The year ended with an average price of 83 $/bbl, a lower reference compared to the 101 $/bbl of 2022. There was a significant decrease in gas prices, as Henry Hub – reference index in the US - reached an average price of 2.5 dollars per million British thermal units ($/MMBtu), 54% lower than the previous year. The European reference gas index (TTF) price at the beginning of the year was 63 €/MWh (average price in January) but started to decrease to the range of 30-45 €/MWh as EU gas storage reached a level of 86% at the end of the year. The TTF had an average price of 41 €/MWh in 2023, almost three times lower than the 2022 price of 121 €/MWh. In Europe, the reference carbon price of the European Emissions Trading System (ETS) was on average 84 €/ton in 2023, a slight increase from the 81 €/ton average price in 2022. Having a sustainable and secure energy system is a clear priority to many countries, after everything that happened in 2022. Accelerating the energy transition is on the political agenda of so many countries, as well as on the strategic plans of private sector corporations. Throughout the year 2023, several policies were put in place, with the main focus of boosting investors’ confidence back and strengthening industries' competitiveness, so that economies can keep on recovering and businesses have a favourable environment to strive. Global warming in 2023 2023 has become the warmest year on record, according to the European Earth Observation Programme, “Copernicus”. Unprecedented global temperatures from June onwards led 2023 to become the hottest year since we have registers, overtaking 2016, the previous warmest year. In the past months, global temperatures were 1.48° C warmer than the 1850-1900 pre-industrial level and therefore, close to the 1.5°C limit agreed upon in the Paris Climate Agreement. According to the report, it is likely that a 12-month period ending in January or February 2024 will already exceed the 1.5°C threshold. The Intergovernmental Panel on Climate Change (IPCC) made a call in March 2023 for urgent climate action, as the planet seems to be at an inflection point regarding climate change, as chances to keep the 1.5°C temperature goal are narrowing. According to the report, limiting global warming to 1.5°C, requires a peak of emissions before 2025, and reducing them by 43% by 2030, 60% by 2035 and reaching net- zero in early 2050. Global warming has already caused devasting disruptions in ecosystems, populations and economies all around the globe, and impacts seem to be increasingly catastrophic. The year 2023 was no exception and important climate-related events caused widespread damage all around the world. In Libya, and Turkey, torrential rains fell in volumes rarely seen, leading to devastating floods. China was hit by the Doksuri Typhoon, one of the strongest storms in years, that caused significant rainfall and flooding across the country. Extreme hot and dry conditions led to a large number of catastrophic wildfires all around the globe, including Greece (that experienced the largest wildfire ever seen in Europe), Canada, South America and Australia, among 

026 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment others. On the other hand, record droughts were recorded in different regions, including the Amazon rainforest, Mexico and western Africa. Climate negotiations: 28 th Conference of the Parties of the UNFCCC (COP 28) The 2023 United Nations Conference of the Parties (COP) took place in Dubai, in the United Arab Emirates (EAU) from 30 November to 12 December. For the first time, countries agreed on the need to “transition away from fossil fuels in energy systems” in a “just, orderly and equitable manner” to achieve net-zero by 2050\. This was the main conclusion to the first Global Stocktake (the inventory on global climate action and support that informs the updates to countries’ Nationally Determined Contributions or NDCs). However, the deal did not include concrete actions and no timescale was specified. Besides, given the omission of the terms “phase-out” or “phase-down” could be a sign of lack of ambition according to some countries. Countries home to at least half the world’s renewable energy capacity also signed a pledge to triple the world’s renewable energy capacity by 2030 to at least 11 TW and double global energy efficiency improvement rates from around 2%/year now to more than 4%/year by 2030. The renewables’ target will require an unprecedented acceleration in renewables’ deployment, although according to the International Energy Agency, it is an “ambitious, yet achievable goal”. European Energy Policy Renewable Energy Directive The Renewable Energy Directive is the legal framework for the development of clean energy across all sectors of the EU economy. Given the need to speed up the European clean energy transition as mandated in the “Fit for 55” package, the Renewable Energy Directive EU/2018/2001 for the period 2020-2030, was revised in 2023. The revised Renewable Energy Directive, the so-called “RED III” was published on 31 October 2023 and entered into force 20 days later. The RED III aims to increase the share of renewable energy in the EU’s overall energy consumption to 42.5% by 2030, with a further indicative target of 2.5%. To achieve this target, the Directive calls for an acceleration of permitting procedures and sub-targets on the industry, transport and buildings sectors are also imposed. Regarding the acceleration of permitting procedures, the Directive includes measures to considerably speed up permitting for new projects. A key measure is the definition of so- called “Renewable acceleration areas” that have to be defined by Member States (MS), and in which renewable projects will benefit from shorter and simplified permitting processes. In particular, renewable energy sources (RES) projects (or collocated energy storage facilities) in these areas will be exempted from the Environmental Impact Assessment and permitting times shall not exceed one year (two years for offshore projects) and six months for repowering of plants and for new installations with an electricity capacity of less than 150 kW. Outside such areas, the process should not exceed 24 months. The Directive furthermore mandates that the lack of an answer from the administration within the prescribed deadlines will result, in some cases, in tacit approval of the specific administrative step. Under the new Directive, the deployment of RES will also be of “overriding public interest” limiting the grounds of legal objections to new installations. Member States must transpose the RED III to national law by mid-2025. Wind Power Package The European Commission launched the so-called “Wind Power Package” (WPP) in October 2023, which aims to accelerate the roll-out of wind energy in Europe and to strengthen the competitiveness of European wind energy manufacturing. The WPP tackles specific challenges faced by the European wind power sector, such as the uncertain demand for wind turbines, high inflation, shortages and increasing costs of raw material costs, and slow and cumbersome permitting processes. The final goal is to achieve the 420 GW of wind energy that the REPowerEU targets by 2030. The WPP proposes a Wind Power Action Plan which sets out 15 concrete and immediate actions, structured in 6 key pillars. 

027 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment Some measures aim at accelerating the deployment of wind through an increased predictability and faster permitting, with a strong emphasis on the digitalisation of national permitting processes. The WPP also aims at improving auction design. MS will ensure auction prices are indexed to reflect increases in costs and will use prequalification criteria in critical areas such as cybersecurity. The WPP also calls for an increased visibility through wind pledges, publication of the mid-term auction schedules and of long-term plans for renewables deployment. Access to finance is another key pillar. The EC aims to double the EU Innovation Fund budget for clean technologies and to increase support for wind-related activities in the revised Strategic Energy Technology Plan (SET Plan) focusing on research and innovation in the wind manufacturing sector. On this regard, the EC launched a €4bn call under the Innovation Fund with grants aimed to support investment in clean tech manufacturing. Likewise, the European Investment Bank changed its lending rules to support factory investment and launched a new €5bn counter-guarantees scheme for wind turbines manufacturing. To ensure commitment from Member States, a dedicated Wind Power Charter was released in December 2023, and was signed by 24 Member States and endorsed also by Bulgaria and Croatia and more than 300 companies from the wind energy sector (such as EDP Renewables). Market Design Reform Throughout the year 2023, the EU worked on the electricity market design reform, and in December 2023 the proposal was approved. This reform intended to build an energy system based on clean technologies, while at the same time promoting a competitive environment for businesses and a stable price setting for consumers. To reach such goals, different proposed measures are moving forward, some of them highlighted here: • investments in new generation such as wind, solar, geothermal, hydro without reservoir, and nuclear, will be backed through public support in the form of two-way contracts for difference, or an equivalent scheme • member states shall provide public guarantees to promote new renewable power purchase agreements under certain conditions • suppliers (with more than 200 thousand customers) will be obliged to offer fixed-term and fixed-price contracts with a duration of at least 1 year • member states may apply flexibility support schemes to non-fossil technologies, including storage and demand-side response, in the form of capacity payments. Net-Zero Industry Act The Net Zero Industry Act was published in March 2023 to strengthen European manufacturing capacity and promote measures to overcome barriers to the scaling up of such capacity. Some specific targets were set to achieve these outcomes, namely increasing the production of zero-impact technologies, in order to meet at least 40% of the EU's annual needs for the deployment of strategic zero-impact technologies by 2030. Solar photovoltaic, onshore wind, offshore wind, batteries, and electrolysers are some of the technologies among the list considered in this Act. To ease conditions and stimulate investment, this legislation sets several proposals, namely: • accelerating permitting and lowering the administrative burden to the implementation of net-zero technology manufacturing projects • facilitating market access, for example, by including sustainability and resilience criteria for public procurement and auctions • attracting investment through the Net-Zero Europe Platform and the EU Hydrogen Bank and • fostering innovation through the creation of regulatory sandboxes. Critical Raw Materials Act Clean technologies rely heavily on critical materials, and so the demand for these is expected to rise significantly in the coming years. To secure the supply of strategic raw materials, the European Commission proposed in March 2023 the Critical Raw Materials Act. The legislation identifies a list of strategic raw materials that are needed for key technologies, which in turn are critical for the EU to pursue its green ambitions and goals. The Act sets a target of having no more than 65% of the EU’s annual consumption of each strategic raw material at any relevant stage of processing from a single third country by 2030\. By diversifying the supply chains, the EU will be able to mitigate the risk of external dependencies. 

028 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment The legislation is in provisional agreement by the Council and the Parliament, and it sets the following non-legally binding targets: • at least 10% of the EU's annual consumption of strategic raw materials, by 2030, must come from internally conducted extraction • at least 40% of the EU's annual consumption of strategic raw materials, must come from internally conducted processing, by 2030 • least 25% of the EU’s annual consumption must come from internally conducted recycling, by 2030. US Energy Policy The Inflation Reduction Act, which came into effect on January 1, 2023, is the most significant legislation in the history of the United States. It aims to provide funding, programs, and incentives (such as tax credits) to accelerate the transition to a clean economy. This is intended to reduce the costs of renewable energy for organizations, NGOs, businesses, and academic institutions. The Treasury has informed how investment tax credits will apply to offshore wind and batteries, while also detailing how domestic content and apprenticeship tax credit-adders can be applied. The Department of Energy (DOE) has announced 3.5 billion USD to boost domestic production of batteries, 1.3 billion USD for transmission expansion, and various smaller grants for equal justice and innovation projects focusing on low-income and coal communities. The Federal Energy Regulatory Commission (FERC) published Order No. 2023 on September 6, 2023. This rule will go into effect on April 3, 2024, and is meant to both reduce backlogs of projects seeking to connect to the transmission system and provide more concrete deadlines throughout the process. The rule will adopt a cluster study approach for examining gris upgrades and additions rather than studying individual proposals. The Environmental Protection Agency (EPA) proposed greenhouse gas emissions limits for coal- and gas-fired power plants in May 2023. The limits vary based on plant size, whether they are existing or new, and how often they are online. These proposed limits would require the affected plants to either add carbon capture technology, co-fire with ‘green’ hydrogen, or retire. These rules are not yet final and there has already been pushback from various states, Independent System Operators (ISO) and Regional Transmission Organizations (RTO), citing reliability concerns. It is expected that the final version issued by the EPA will undergo heavy legal scrutiny. 

029 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment 2.1.2. The evolution of renewables around the world in 2023 According to the International Energy Agency (IEA), in 2023, the amount of renewable energy capacity added to energy systems grew by 50% globally compared to the previous year, marking the fastest growth rate in the last two decades, with an estimated addition of 507 GW. Photovoltaic energy contributed to one-third of the global capacity increase. The IEA expects an even faster growth in the next 5 years, increasing the chances of achieving the goal of tripling renewables’ global capacity by 2030 as agreed at the COP 28 Climate Change Conference. According to the IEA, solar PV and wind will account for 95% of global renewable additions through 2028. Supportive policy environments and the improving economic attractiveness of these two technologies remain the most important drivers behind the expected growth. The astonishing renewables growth in 2023 was mainly driven by China, that installed as much solar PV as the entire world did in 2022. The growth was also supported by all-time records of new renewable additions in Europe, the US and Brazil. Wind According to IEA estimations, global wind additions could have reached 108 GW in 2023. This would represent, the highest figure ever seen, and the first time the wind sector surpasses the 100 GW threshold. Long-term fundaments remain strong for the coming years, and supportive policies in China, the US and Europe in particular, are expected to boost wind additions in the coming years. However, short and medium-term challenges in project execution remain. New installations in China could have hit a record and grow to 59-65 GW 1 as provinces are accelerating to meet the targets set out in their five-year plans. India could have commissioned more than 3 GW of new wind projects, the highest figure since 2017. In the US, new installations have grown at a moderate pace, with around 7-9 GW built in 2023\. Although developers seem to be taking advantage of new tax credits from the Inflation Reduction Act, it still takes time to bring projects online. At the end of Q3 2023, nearly 147 GW of onshore wind were operating in the US, according to the American Clean Power Association (ACP). Additions are expected to pick up in 2024. 1 At the time of preparation of this report, final data from the Global Wind Energy Council (GWEC), the American Clean Power Association (ACP) or Wind Europe, had not been released. Experts consulted include IEA, S&P, Bloomberg New Energy Finance, Wood MacKenzie 2 Data from the German Wind Energy Association (BWE) 3 Data from the National Electricity Energy Agency (ANEEL) The European Union built a record 17 GW of new wind capacity in 2023, according to preliminary data from Wind Europe. Wind energy is expected to be a fundamental piece of Europe’s clean energy transition, but these figures are still well below the required capacity to hit the 2030 target (30 GW/year). Particularly, onshore wind energy still faces some significant obstacles contributing to the observed delay, namely difficulties in obtaining licensing, network restrictions, and increased production chain costs. Germany was the largest market, followed by the Netherlands and Sweden. Germany 2 installed 2.9 GW of onshore wind power in 2023, more than the previous year (2.4GW). In addition, around 7 GW were approved in 2023 and 6.4 GW awarded in tenders, figures never seen before. Spain commissioned 1.6 GW of onshore wind facilities, a very promising figure but still below the 4 GW per year that would be necessary to reach the 63 GW 2030 wind target proposed in the National Energy and Climate Plan (NECP) submitted to the European Commission for approval. In Latin America, Brazil remains the largest wind market, with expected record additions of around 4.9 GW 3 . This growth could bring Brazil’s total installed capacity to nearly 28 GW, making it the country’s second-largest generating technology, after large-scale hydro. Regarding offshore wind, around 12-14 GW of new offshore installed capacity were globally added in 2023, surpassing the 2022 figure (9 GW). Rising costs and supply-chain bottlenecks have hindered the industry, resulting in project delays and cancellations. China remains the main market, with around 7-8 GW installed. According to Wind Europe preliminary data, Europe (including the UK) installed 4.2 GW of offshore wind capacity, up 40% from 2022. Netherlands led offshore, as it commissioned the 1.5 GW Hollandse Kust Zuid wind farm, the world’s largest operational wind farm, followed by UK and France. Solar PV 2023 is on course to become another record-breaking year for solar PV, with the IEA forecasting around 373 GW of new installed capacity, a 63% increase compared to 2022. This shows the enormous growth potential of the technology, continuously breaking 

030 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment records in the last years. All solar PV segments have witnessed considerable growth in in 2023\. According to experts, around 55% of new solar PV capacity would be utility-scale projects and the remaining ones small-scale (mainly residential and commercial systems). China could have added between 180 and 200 GW of solar PV capacity, according to data released by the National Energy Administration (NEA). The growth was supported by China “30-60” goal of reaching peak emissions by 2030 and net zero by 2060. Other major markets in Asia include India (≈10 GW expected), Japan (≈8 GW) and the Republic of Korea (≈3.5 GW). In the US, approximately 31-33 GW of solar PV capacity could have been added in 2023, according to analysts consulted 4 . Solar PV is the fastest-growing source of electricity in the US, making up almost half of all new power capacity in the first three quarters of 2023. According to the American Clean Power Association, more than 83 GW of solar PV were operating at the end of the third quarter of 2023. The EU installed a record 56 GW of solar capacity in 2023, well above the 40 GW added the previous year, according to SolarPower Europe. In 2023, Germany returned to the top spot with 14.1 GW of new capacity, followed by Spain with 8.2 GW, Italy with 4.8 GW, Poland with 4.6 GW and the Netherlands with 4.1 GW. In Central and Eastern Europe, Czech Republic, Bulgaria, and Romania crossed the 1 GW threshold for annual solar additions. In Latin America, Brazil is expected to remain the main market in 2023, with around 12 GW installed, according to the Solar Association ABSOLAR. Storage Energy storage systems allow energy consumption to be separated in time from the production of energy. Electricity storage and, more in particular, Battery Energy Storage Systems (BESS), are a key tool in achieving a low-carbon future, as they allow to accommodate larger shares of variable renewables (typically wind and solar PV) allowing to achieve a greater system flexibility. Batteries can not only shift excess renewable energy to hours when there is less production, but they can also provide a wide range of services to the system, such as frequency response, reserve capacity, black-start capability among other grid services. In addition to providing grid stability services, BESS could also be used by TSO and DSOs to defer costly grid investments. All in all, BESS can be a valuable tool to 4 Experts consulted include IEA, SEIA (Solar Energy Industries Association), American Clean Power Association, S&P, Bloomberg New Energy Finance, Wood MacKenzie 5 Source: IEA (WEO 2023) according to the data of the Stated Policies Scenario (STEPS) reduce curtailment, an increasingly important challenge in countries with high renewables’ penetration. Batteries offer enormous deployment and cost reduction potential, according to analysts. In that sense, utility-scale battery storage deployment is already happening on a very large scale, and its capacity is expected to increase nearly 85-fold by 2050 5 . However, many challenges lie ahead. On the one side, BESS supply chains are today highly geographically concentrated. According to the IEA, China concentrates around 75% of the manufacturing capacity, and the share is not expected to significantly decrease in the next years. Therefore, countries need to diversify supply chains and/or develop industrial strategies for batteries’ manufacturing. The access to critical minerals, essential for BESS production, is also a key challenge for most of the countries. On the other side, regulatory and market conditions are not always well-suited to compensate batteries for all the services they can provide, and in most of the countries BESS projects are not attractive to investors. Therefore, it is important to enhance the returns they can yield, monetizing positive externalities and minimizing the risks associated with the projects. This can be achieved through different options including: (i) allowing BESS participation in capacity markets (which need to provide long-term contracts) (ii) designing ancillary services well-suited for BESS (iii) allowing BESS participation in auctions (standalone or paired with renewables), (iv) granting aids or grants when necessary and (v) enabling the PPA market. 

031 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment 2.1.3. Regulatory Framework Renewables, clients & energy management Renewables Belgium • Green certificate scheme (GC) • Wind farms receive market price plus GCs per MWh produced. • Number of GC/MWh (kECO) for new plants’ contracts was revised in 2019, 2021, 2022 (exceptional update) and 2023 • Last update (Dec-22, for 2023 onwards) the kECO decreased from 0.52 to 0 GC/MWh due to high electricity prices • The minimum price for GCs is set at 65€/GC in Wallonia. Poland • Electricity price can be stablished through bilateral contracts • Wind farms commissioned before 2018 are supported through a Green Certificate scheme (GC). Wind receives 1 GC/MWh during a 15-year period. Electricity suppliers have a substitution fee for non-compliance with GC obligations • Since 2018, wind farms are supported by 15-year two-side Contracts-for difference awarded through auctions. Italy • Wind farms in operation prior to 2012YE are under a feed-in-premium scheme applicable during the first 15 years of operation • Wind farms commissioned from 2013 to 2017 are supported by a 20-year floor CfD scheme, awarded through competitive auctions • Since 2017, wind farms are supported by a 20-year two-side CfD scheme. Portugal • Wind farms commissioned before 2006 are subject to a Feed-in-tariff (FiT) whose value is correlated with production and indexed to CPI. Initial tenure was the soonest of 15 years (or until 2020) or 33GWh/MW but in was increased 7 years (tariff extension) with a cap and floor scheme in exchange of annual payments between 2013 and 2020 • Wind farms under the new regime (COD after 2006) are subject to a FiT for the soonest of 20 years from COD of 44 GWh/MW. Tariff value is also indexed to CPI • Since 2019, solar projects are awarded following a new auction system • Floating PV projects awarded in 2022 auction has a 15 years CfD contract with a negative strike price (the original project pays for injecting the energy in the grid in exchange of securing grid capacity that can be used by over equipment and hybrid). Spain • Under RD 413/2014, wind energy projects receive pool price and a premium per MW in order to achieve a target return defined by regulation • RDL 17/2019 has set the target return (TRF) @7.398% for WF’s prior to 2013 for the next two regulatory periods (until 2031) and @7.09% for new installations for the current regulatory period (until 2026) • Premium calculation is based on standard assets (standard load factor, production and costs) • Since 2016, all the new renewable capacity is allocated through competitive auctions. • In 2020, RD 960/2020 defined the framework for a new auction mechanism • Since 2021 several auctions have taken place to grant the new scheme. Colombia • Colombian wind farms are awarded 15-year contracts though competitive pay-as-bid auctions. Contracts are signed with distribution companies • Additionally, Colombian wind farms must secure reliability charge contracts, which provides a monthly payment in exchange of having part of their capacity available when the system is under tight supply conditions. Brazil • Old wind farms receive support under a feed-in program (“PROINFA”) • Since 2008, competitive auctions award 20-year PPAs to winning projects 

032 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment • Electricity may also be sold under private PPAs. France • Old wind farms receive Feed-in tariffs for 15 years, with values depending on their COD and load factors achieved • A transitory Contract-for-difference scheme was released in December 2016 in which wind farms having requested a PPA in 2016 would receive a 15-year CfD, being the strike price very similar to the previous FiT. This scheme was closed in December 2019 • From 2017 onwards: • Wind farms with 6 wind turbines (or less, and with 3MW/WTG maximum) can request a 20-year CfD which strike price ranges from 72€/MWh to 74€/MWh depending on turbine’s diameter and may include a FiT reduction when a yearly generation cap is reached. Since April 2022, additional tip height restriction (below 132m) has been implemented • Wind farms not eligible to CR17 need to participate in competitive tenders in order to obtain a 20-year CfD • A new set of rules (“Cahier des Charges”) that will govern auctions (both technology- specific and neutral) from H2 2021 until 2026 were published in August 2021 Romania • Wind assets (installed until 2013) received 2 GC/MWh until 2017 and 1 GC/MWh after 2017 completing 15 years: • 1 out of the 2 GC earned until March 2017 is postponed and can only be recovered gradually from January 2018 • Solar assets received 6 GC/MWh for 15 years: • 2 out of the 6 GC earned until December 2020 are postponed and may only be recovered gradually from 2025 • GC are traded in the market under a cap and floor system (cap 35.0€ and floor €29.4€) • Wind assets (installed after 2013) receive 1.5 GC/MWh until 2017 and 0.75 GC/MWh afterwards until completing 15 years • Solar PV facilities (installed after 2014) only receive 3 GC • The GCs issued after April 2017 and the CGs postponed to trading from July 2013 will remain valid and may be traded until March 2032. Greece • Renewable projects in Greece are supported by a 20-year feed-in premium (Contract- for-Difference) awarded through auctions • In 2022, Greece launched a new support system, based on two-way contract-for difference contracts, awarded through auctions: • For both onshore wind and solar installations, support will be awarded through a joint competitive tendering procedure, with minimum reserves per technology of 30% Hungary • Renewable projects before 2016 benefited from a feed-in tariff scheme (“KÁT system”) • In 2016 the FiT was closed to new projects and replaced by a new support system (“MÉTAR system”) consisting of 15- year Contracts-for-Difference granted through technology-neutral tenders. Chile • Technology-neutral auctions, for renewable and non-renewable technologies award 15-year power purchase agreements with distribution companies • Large non-regulated customers can also enter PPAs directly with generators or organize a public auction. UK • Since 2013, renewables are supported through a 15-year two-way Contracts-for- difference, awarded through auctions, that have progressively replaced the former Green Certificate scheme: • the “established technologies” which include onshore wind and solar PV, compete for budgets in each allocation round. Less mature technologies have a separate “pot” of allocated budget. For the first time, in 2023 auction, offshore will compete with mature technologies. Vietnam • Onshore wind projects were supported under two different Feed-in-tariff regimes: • projects were granted a 20-year PPA with EVN, the state utility • as the latest feed-in-tariff was closed for new projects, a new support scheme is expected to be released soon - most likely, competitive auctions will be introduced 

033 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment • Solar PV projects have also been remunerated under two different feed-in-tariff regimes and the government is also planning to introduce a pilot auction program • FiT schemes are no longer available; however a transitional scheme has been published for renewable projects that had a FiT signed but failed to COD on time. Transitional scheme would be subject to a price negotiation with EVN. Singapore • No support is given to large-scale renewable energy • Solar PV development is mainly incentivized through public agencies tenders like the SolarNova programme or JTC tenders : • Solarnova was launched in 2014 by the Housing Development Board (HDB). It aggregates demand for solar PV across some government agencies buildings to achieve economies of scale. Since 2014, 8 SolarNova tenders have been launched • JTC is a government agency under the Ministry of Trade and Industry that launched several Solar PV tenders under the Solarland and SolarRoof programme. There have been fewer and smaller auctions than in solarnova's program. Clients & Energy Management Spain Main measures with impact on the retail activity and energy management are the following: • Order TED/81/2023, of January 27, established the following percentage distribution of the amounts to be financed related to the Social Bonus by activity for that year: production, 46.44%; transmission, 1.09%; distribution, 3.93%; commercialization, 47.56%; and direct consumers in market, 0.98% • Circular 1/2023, of February 7, reformulated the incentives for the system operator introduced by Circular 4/2019, of November 27, to better optimize resources in the dynamics of the system operation, as well as to better adapt to the energy transition objectives • Resolution of February 23, 2023, of the National Commission of Markets and Competition, approved the operating rules for the daily and intraday electricity markets to adapt to the economic regime of renewable energies and the evolution of the market agents committee • through Order TED/296/2023, of March 27, the contribution obligations to the National Energy Efficiency Fund in 2023 were set: (i) a final energy savings target of the National System of Energy Efficiency Obligations of 204.12 ktoe or 2,373.95 GWh; (ii) the financial equivalence for the calculation of economic contributions to the National Energy Efficiency Fund, set at 1.928 million euros per saved ktoe or 165,778.16 euros per saved GWh, based on the estimated average cost to mobilize investments in all sectors of action necessary to achieve the annual savings target; and (iii) the corresponding savings obligations, calculated according to the procedure established in its annex I, as well as its economic equivalence for the year 2023. • Order TED/567/2023, of May 31, called for access to the regulatory testbed provided for in Royal Decree 568/2022, of July 11, which establishes the general framework of the regulatory testbed for the promotion of research and innovation in the electricity sector. • subsequently, through Royal Decree 446/2023, of June 13, which modifies Royal Decree 216/2014, of March 28, reduced the volatility of the voluntary price for the small consumer (PVPC) by mitigating the effects derived from the electricity price context at the time • Royal Decree-Law 5/2023, of June 28 introduced relevant innovations in (i) e-mobility (administrative simplification), (ii) permitting of renewable generation facilities, (iii) energy communities (Renewable Energy Communities and Citizen Energy Communities), remuneration for cogeneration, biomass, and waste (RECORE) (updating remuneration parameters for the period 2023-2025), and electro intensive consumers (among other issues, extending the 80% exemption from electricity tolls until December 31, 2023) • Resolution of October 19, 2023, approved the new electric operation procedure 7.5 on the active demand response service, which aims to regulate the operation of the specific active demand response balance service of the Spanish peninsular electrical system, to address situations in which an insufficiency of tertiary regulation reserve is identified • through the Resolution of the General Water Directorate, EDP España, S.A.U. was authorized to modify the characteristics of the concession for the hydroelectric use of 142 m3/s of the Nalón River for hydroelectric production (135.6 MW) at the Tanes dam to include the hydroelectric use of 20 m3/s at the Rioseco reservoir dam (3.3 MW), Nalón River, in the municipality of Sobrescobio (Asturias) • Resolution of November 2, 2023, of the National Commission of Markets and Competition, approved conditions and requirements for the execution of a regulatory demonstration project for voltage control in the Spanish peninsular electric system • Resolution of the General Water Directorate, announcing the public tender for the exploitation of the hydroelectric use of La Riera, in the municipality of Somiedo 

034 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment (Asturias), the public tender for the exploitation of hydroelectric power plant “La Riera” was published, granting a three-month period for offers presentation • finally, Royal Decree-Law 8/2023, of December 27 introduced relevant regulatory changes in several areas, including: (i) regarding Gas Clawback (reduction of remuneration for electricity production activity) and Cap gas (adjustment mechanism or Iberian exception), no measures were contemplated, therefore these mechanisms ceased to be applicable as of January 1, 2024; (ii) progressive recovery of the Value Added Tax on Electric Energy Production (IVPEE); (iii) extension of the energy tax; (iv) progressive recovery of taxation, articulated through a progressive increase in VAT and the special tax on electricity; (v) continuity of the 80% reduction in electricity tolls for electro intensive consumers; (vi) extension and flexibilization of deadlines for the development of new renewable installations; (vii) implementation of measures to provide greater network capacity for self-consumption; (viii) extension until June 30, 2024, of the following measures to protect vulnerable consumers: discounts on the Social Bonus, Last Resort Tariff (TUR) for property communities, maximum limit for the revision of the TUR for natural gas, measures to flexibilize electricity and natural gas contracts, limitation of the maximum sale price of packaged liquefied petroleum gases, and prohibition of interrupting basic supplies to vulnerable consumers due to non- payment; (ix) publication of new unit values for the financing of the Social Bonus; (x) promotion of pumping facilities by introducing various measures in the Water Law, both for existing pumping and for new facilities under development; and (xi) adaptation of renewable energy auctions to include criteria for measuring environmental and social quality, innovation, and job creation. Auctions may include non-economic award criteria with a maximum weighting of 30%. Portugal With impact on the generation activity, the regime for the use of water resources was changed by removing the right of preference of the previous entity with the hydro concession in future tender procedures when the respective concession period expired. Measures related to the Hydro Strategic Reserve (“Reserva Estratégica Hídrica”) were suspended which, since October 1, 2022, determined the temporary suspension of the use of water resources of 15 hydropower plants (13 belonging to EDP), until the minimum levels of storage of their useful capacity are reached. Concerning the retail activity, the financing mechanism for the electricity social tariff has been changed, shifting from being supported only by producers under the ordinary regime to generators, retailers and other market agents in the consumption function (not applicable to TSO and DSO). In the electricity tariffs, the regulator (ERSE) carried out an update of the energy tariff in April 2023, reflecting a decrease of 5€/MWh, which was effective from April 1 st to June 30 th . Additionally, exceptional tariffs were set for the second half of 2023, with an average increase in network tariffs (TAR) of 55 €/MWh and the maintenance of the transitional tariff for end users (TTVCF) in the normal low voltage (BTN), compared to the previous semester. For 2024, an increase of 2.9% in TTVCF in BTN and an average increase of 66 €/MWh in TAR were approved, comparing with the previous year's average. Regarding the electricity sector's tariff debt, the tariffs foresee an ex-ante debt of 1.995 billion euros by the end of 2024, representing an increase of 1.116 billion euros compared to the tariff debt at the end of 2023. Related to gas tariffs, ERSE proceeded with an updated to the energy tariff during the gas year Oct 2022-Sep 2023, increasing 2€/MWh from January 1 st to September 30 th , 2023. Gas tariffs and prices for the gas year Oct 2023-Sep 2024 were also approved, with an 1.3% increase of the transitory tariff to the end user in low pressure, in force from October 1 st , 2023, onwards. Networks Spain Given the current crisis resulting from the conflict between Russia and Ukraine, the main measures taken have been aimed at reducing the impact of the rise in energy prices, as well as encouraging savings and promoting renewable energies. Regarding the distribution activity, the main measures introduced were the following: • resolution of January 19, 2023, of the National Commission of Markets and Competition, which provisionally establishes the remuneration of electricity distribution companies for the year 2023, established a transitional regime for the year 2023 applying the remuneration approved by Order TED/749/2022, of July 27. That transitional regime was established without prejudice to the effects that, on the remuneration of said year, may arise from appeals filed against Order TED/490/2022, of May 31, which executes the judgment of the Supreme Court in relation to the “lesividad” of Order IET/980/2016, of June 10, which establishes the remuneration of electricity distribution companies for the year 2016. On this date, Supreme Court has upheld the appeal 726/2022 filed by Viesgo Distribución Eléctrica, S.L., declaring Order TED/490/2022 to be unlawful, and 

035 Part I Integrated Annual Report 2023 Strategic Approach | Business Environment recognizing its right to have its remuneration set based on the content of its reformulated accounts as of December 31, 2014 • Royal Decree 314/2023, of April 25, develops the procedure and requirements for granting administrative authorization for closed electricity distribution networks • through Resolution of December 21, 2023, of the National Commission of Markets and Competition, which establishes the values of the access tolls to the electricity transmission and distribution networks applicable from January 1, 2024, the prices of the terms of contracted power and active energy of the transport and distribution tolls applicable to consumers, self-consumers for the energy demanded from the grid, and generators for their own consumption were set for the year 2024 • Royal Decree-Law 8/2023, of December 27, established a transitional regime for electricity tariffs, extending until 2024 the application of those provided for in Order TED/1312/2022, of December 23, until new ones are established by ministerial order. As of this date, the aforementioned order awaits publication • regarding settlements of regulated activities in the electricity sector, the most recent development is the publication of the Resolution approving the Provisional Settlement nº 11 of 2023 for regulated activities in the electricity sector, dated January 18, 2024. Portugal In the distribution activity, standard documents were published that regulated the public tender procedure which aims to allocate the low-voltage electricity networks concessions. Brazil Regarding the liberalization of the Brazilian power market, since January 2024 consumers with less than 500 kW load and voltage levels equal to or greater than 2.3 kV, represented by retailers, can choose their own energy suppliers. The Ministry of Mines and Energy (MME) launched a Public Consultation to discuss the market liberalization for low voltage consumers from 2026 onwards. To choose their energy supplier, low voltage consumers must also be represented by a retailer. The result of this Public Consultation has not yet been published. Law 14,300/22 created the regulatory framework for mini and micro distributed generation (DG) in Brazil. The Law established a transition period after which DG will have to start paying for the grid fees according to the amount of electricity injected into the grid. The enactment of this Law brings legal security and regulatory stability to foster these investments, incentivizing clean energy sources. The main topics addressed by the Law are: • existent DG (grid fees exemption until 2045): mini and micro-DG already installed will only pay a partial grid fee if there is a positive difference between the total energy consumption and the energy production injected into the grid. Also, mini and micro-DG that have requested access to the grid until January 6 th, 2023, can benefit from the exemption regime • new DG (tariff transition): the Law created a transition period, varying from 6 to 8 years, for new DG to gradually pay for grid fees until 2028. The subsidy is matched by resources from Conta de Desenvolvimento Energético \- CDE. Regarding the concession renewals of distribution utilities, the MME launched a Public Consultation to design the guidelines for the renewals. In summary, the renewals – and not new bidding processes – are designed with the implementation of social measures with a focus on energy efficiency measures. Furthermore, the MME proposed the same indexes for quality sets and economic health of the utility. The renewals' process still awaits the enactment of a Decree and the opening of a public consultation by ANEEL to discuss with society the terms of the new concession agreement, stages of which are expected to follow along 2024. Regarding transmission companies, Decree 11,314/22 determined that transmission concessions are to face new bidding processes at the end of their contractual term, being the concession renewal the exception (unfeasibility of bidding or in case of any prejudice for the public interest). This Decree was preceded by a Public Consultation opened by the MME in which EDP included some contributions. Between 2024 and 2032, twenty-four transmission concession agreements will expire. It is worth noting that EDP's first transmission contract expires in January 2043. 

036 Part I Integrated Annual Report 2023 Strategic Approach | Materiality 2.2. Materiality EDP's Materiality analysis process has been continuously developed since 2016, through a comprehensive methodology, standardized across the group and detailed in a specific report available at www.edp.com. This process is conducted every two years, in alignment with the revision of the Business Plans, and enables the identification of the relevance of non-financial issues for stakeholders, cross-referencing it with their relevance to the business priorities and strategy. The analysis supports decision-making and strategy development within the organization, particularly in terms of sustainability performance assessment. The main stages of the materiality process are outlined in the infographic on the right. EDP's methodological approach to defining materiality incorporates the concept of double materiality, as defined by GRI Standards. This alignment underscores the importance given by the group to the relevance of the issues for society, in which it takes into account their impact on its stakeholders. As the concept of double materiality gains prominence in the international regulatory landscape, namely with the guidelines set by the European Financial Reporting Advisory Group and within the International Sustainability Standards Board, EDP is adjusting its methodology for identifying material themes for subsequent reports. This adaptation aims to align with the evolving expectations of stakeholders and uphold the company’s commitment to society and the environment. In 2023, the materiality was revised to incorporate the Business Plan for 2023-2026. Additionally, an alignment with the CSRD was initiated, integrating the materiality themes and categories of 2022 with those of the ESRS standards. Fourteen material themes have been identified, and their relevance to both society and business is positioned in accordance with the matrix presented on the following page, highlighting: 1\. Climate Change – Climate change stands out for its high relevance to both society and business. This emphasis aligns with the global concern regarding this issue and is intricately integrated in the strategy of EDP. This overarching theme encompasses three key issues: (1) adaptation to climate change; (2) mitigation, involving decarbonization solutions, such as sustainable mobility and energy efficiency; and (3) the promotion of renewable energies. 

037 Part I Integrated Annual Report 2023 Strategic Approach | Materiality 2\. Supply chain – The growing relevance of the topic for business and society is due to the increased importance given to environmental criteria within the supply chain, namely the reduction of CO2 emissions in the context of decarbonisation, in light of global goals. Additionally, under the external pressures from the market and regulations, equipment traceability has emerged as a key factor in avoiding and mitigating indirect risks related to social and environmental concerns. 3\. Biodiversity and ecosystems – The new Global Biodiversity Framework elevates the urgency of halting biodiversity loss and preserving the ecosystem services provided by nature. Companies need to accelerate their efforts to assess biodiversity and ecosystem- related impacts and dependencies, manage associated risks, and adopt a net gain approach. Their strategy and business model should be adjusted accordingly. Prioritizing actions to avoid, mitigate, restore, and compensate is essential for fostering responsible business practices. The Materiality process also makes it possible to identify the degree of priority given by each stakeholder group to sustainability issues. This analysis shows a natural dispersion of the relevance attributed by various stakeholders to the analysed themes, inherently related to their nature and relationship with the company. The figure in the next page details the identified themes, aggregated by the degree of relevance attributed to each of the stakeholder groups.

039 Part I Integrated Annual Report 2023 Strategic Approach | Risk Management 2.3 Risk management 2.3.1 Risk governance model The EDP group adopts a risk governance model, widely accepted in most relevant literature, that relies on the idea of three internal lines of defence for the organisation - which can be supplemented, in certain situations, by a fourth external line of defence, in the form of external auditing and regulation/supervision 1 . Three Lines of Defence Risk Governance Model 1 IIA Institute of Internal Auditors, Position Paper, The IIA’s Three Lines Model: An update of the Three Lines of Defense, July 2020 Each line of defence has designated entities and forums that are officially set up to implement each line of defence at corporate and Business Unit levels, preventing any overlap or omission and encouraging collaboration and coordination between the different areas. Risk management is embodied both by the Risk Global Unit and by the risk areas of the different Business Units (led by the respective risk officers), which report functionally to the former, ensuring fluid articulation and communication regarding the main sources of exposure and risk mitigation measures. Moreover, the group has Risk Committees at both corporate level and at Business Units, where top management and relevant specialists meet to examine, discuss, and advise on key risk exposures for the group, their limits and mitigation actions. The Internal Audit Global Unit, as the third line of defence, performs internal audits on the group’s processes that manage, control, and monitor the different risks it faces. To do this, annually, it decides which audit activities should be part of the next year's activity plan, based on, among other things, the inputs and concerns of the first and second lines of defence. In this regard, for 2023, the Internal Audit Global Unit did internal audits to the risk management process with a focus on: counterparty risk management; market risks related to Energy Management; financial risks; security and cybersecurity; and compliance with policies and procedures, promoted by the second lines in the areas of Compliance and Internal Control. The Internal Audit Global Unit’s Director is part of the Risk Committees, thus facilitating the monitoring of projects carried out by RISK. RISK regularly meets with the General and Supervisory Board and the Financial Matters Committee/Audit Committee to monitor the effectiveness of the risk management system. The FMC/AUDC defines in its annual planning sessions dedicated to monitoring the main exposures and risk management issues, addressing matters related to financial, strategic, ESG, business and operational risks. In 2023, RISK had three meetings with the GSB, two with the FMC/AUDC and the yearly meeting of the Audit Committees, addressing several risk issues, namely the monitoring of EDP’s main exposures and Key Risk Indicators, an 

040 Part I Integrated Annual Report 2023 Strategic Approach | Risk Management overview of the RISK execution plan (financial and non-financial risks, including ESG risks and climate risks), risk reporting mechanisms, ESG investments criteria, long-term contracting strategy, foreign exchange risk management policy, risk appetite framework review and RISK strategic priorities for 2024. In June 2023, a presentation was also made to this Commission on the project that began in 2024 to prepare the company for the Sustainability Reporting Directive (CSRD), regarding the Internal Control System for Sustainability Reporting (ICSRS), as well as climate risk analysis and the ESG risk framework. EDP’s external audits also contribute to assess the degree of internal compliance with the risk management system. The last external audit took place in 2022 and focussed on assessing the level of maturity of the Enterprise Risk Management system at group and Business Unit levels. A description of those involved in the EDP group's risk governance model, as well as their respective responsibilities, is available in the Corporate Governance Report and, in more detail, on the EDP website: EDP group Risk Governance Model | edp.com Corporate Functions 

041 Part I Integrated Annual Report 2023 Strategic Approach | Risk Management 2.3.2 Risk appetite The EDP group is exposed to several risks due to its size, and diversity of businesses and geographies in which it operates. Therefore, it recognises risk-taking as an integral and unavoidable component of its activity, both in terms of threat and opportunity. In this context, the group explicitly and implicitly establishes its risk appetite with its stakeholders, at corporate and Business Unit level, through a series of mechanisms: • the development and periodic approval by the Board of Directors of the group's Business Plan, which sets out and explains the main strategic guidelines over a three-to-five-year horizon • rigorous assessment of the risk associated with investment and divestment opportunities carried out by the Business Units and approved by the Executive Board of Directors, supported by the opinion of the Investment Committee • the development of risk management policies, both at corporate and Business Unit level, establishing guidelines, assessment methodologies and exposure limits for key risks 2 • periodic risk maps based on objective, quantitative and comparable criteria, with the aim of analysing exposure to the most relevant risks and taking preventive action to deal with excessive exposure in relation to the established risk tolerance • the development of periodic risk reports for the main risk categories, making it possible to regularly monitor the evolution of current and emerging risks and compare the various exposures against the established limits. Dissemination of said reports in line with the group's strategy and performance metrics to the EBD and GSB • the definition of an internal Risk Appetite Framework, approved by the EBD. The EDP group's risk appetite framework is structured around four pillars: • the governance model identifies the main players in the risk appetite process and their responsibilities • the risk appetite statement formally defines a set of risk appetite statements complemented by risk indicators and thresholds. In terms of positioning, the group has established maintaining a controlled risk profile as a fundamental pillar of its strategy • monitoring and follow-up, defining the key processes of monitoring, update and action plan • and the reporting platform, embodied in a risk appetite dashboard, that allows the EDP group's risk appetite to be monitored. 2 These include, among others, the Enterprise Risk Management Policy, the Risk Appetite Framework Policy, the Energy Risk Management Policy, the Financial Management Policy, the Counterparty Risk Policy, the Insurable Risk Management Policy, the Occupational Health and Safety Policy, the Information Security Policy and the Crisis Management and Business Continuity principles, structure and procedures.

Max Supply of High-Risk Regions Max Suppliers Concentration by Product Monitoring Risk EDP has a comprehensive risk monitoring framework to safeguard its operations and investments, reporting on a recurring basis to the Executive Board of Directors and Risk Committee. At the forefront of this strategy is the annual mapping of risks, complemented by quarterly interim updates, to identify, quantify and prioritise the risks of the different categories of the risk taxonomy. The quarterly risk appetite dashboard is a vital tool that systematically assesses the company's risk exposure, comparing the value of the KRIs with the limits defined in the Risk Appetite Statement. In the table above are some examples of these limits, within brackets. In addition, the Risk Global Unit prepares a fortnightly risk report focused on controlling energy and financial risks, which are more volatile and therefore require more recurrent monitoring. At local level or for individual policies, there are dedicated reports for monitoring risk, focussed on more operational metrics, some of which updated daily. To reinforce the risk monitoring infrastructure, EDP has a group Risk Committee, which includes four annual meetings, as well as risk committees in the different Business Units. These committees play a key role in monitoring risk exposure and defining risk mitigation policies and measures.

Updating the EDP group's Enterprise Risk Management Manual Promoting a solid risk culture throughout the organisation Carrying out a wide range of awareness initiatives, adapted to the different target audiences: • Training on risk issues and new trends in risk management at the Annual Meeting of the Audit Committees, for members of the General and Supervisory Board • Specialised courses for all employees (e.g., ethics, health and safety, cyber security) • Programme to boost the EDP group's network of risk officers: quarterly individual meetings, annual planning meeting, sharing of information in the ERM Repository, quarterly masterclasses, annual meeting of risk officers and participation in Risk Committees • Annual Risk Summit to promote a risk culture and train risk officers and their teams, as well as members of the Risk Committee (such as Internal Audit) and members of the General and Supervisory Board Development of several sessions dedicated to risk for senior management (executives and non-executives): four Risk Committees dedicated to analysing the main risk issues with senior executive management; participation in two sessions of the Financial Matters Committee and three plenary sessions with the General and Supervisory Board Training workshop for members of the Audit Committees and some members of the General Supervisory Board on ESG risks and new trends in non- financial reporting Diagnosis of competences in risk teams, with the aim of defining a structural development plan Implementation of the development plan based on the diagnosis, with the creation of dedicated training programmes 

045 Part I Integrated Annual Report 2023 Performance | Risk Management 2.3.5 Main risks for 2024 EDP group seeks to have a comprehensive view over the key risks it is exposed to, at strategic and ESG, business, financial and operational levels, establishing processes to ensure their monitoring and proactive management. Macro Categories of EDP's Risk Taxonomy The year 2023 continued to be marked by the geopolitical crisis caused by the conflict in Ukraine, resulting in an energy crisis. The financial markets also noted some concern about the sharp rise in inflation and increase in interest rates. Risk management reaffirmed its importance, playing an essential role in this disruptive context. A detailed description of the various risks relevant to the EDP group is available on the EDP website: EDP Risk Taxonomy | edp.com. The table below details the risks expected to have the greatest potential impact on the group's EBITDA in 2024, in an adverse scenario. Risk Risk Description Evolution compared to 2023 Mitigation Measures (not exhaustive) 1 Renewable Production Volumes The EDP group has a material degree of exposure to variations in renewable energy generation volumes, particularly regarding hydro volume, but also wind and solar. A dry year and/or a year with lower wind or solar resources can have a negative impact on the company's results  • Geographical and production portfolio diversification • Long net position in the various markets, with continuous monitoring, protecting the company from the risk of becoming over hedged even in scenarios where there are low renewable resources • For Iberia, compensating for bad water years with greater thermal production • Appraisal of instruments to hedge the volume of renewable generation (hydro and wind). 2 Commodity Prices Changes in commodity prices, essentially due to market exposure in Iberia to electricity, coal, gas and CO2 prices, but also in EDPR's other markets (residual exposure not covered by PPA). These changes may be due to various factors, namely fluctuations arising from supply and demand dynamics or regulatory changes (national or international) and may impact the company's results  • EDP's business with a high percentage of forward contracts with PPAs, being very pro- tected from price variations within these contracts • Integration of generation with retail in several of the most important geographies • Prudent management strategy for residual energy not covered by PPAs, by the Global En- ergy Management Unit, which negotiates and manages coal, gas and CO2 licence contracts, and is also responsible for mitigating price risk via hedging (including exchange rate risk in US dollars, in coordination with the Finance Global Unit). 

046 Part I Integrated Annual Report 2023 Performance | Risk Management Risk Risk Description Evolution compared to 2023 Mitigation Measures (not exhaustive) 3 Capital Gains on Asset Rotation Reduction of capital gains expected from asset rotation activity due to a decrease in the value of assets, because of lower market appetite, a generalised rise in interest rates or exchange rate variations  • Diversification of asset rotation across different geographies (EU, NA, LATAM, APAC, etc.) and currencies (EUR, USD, BRL, PLN, etc.) • Exchange rate risk hedging (Net Investment and transactional), within the framework of the group's financial risk management policy • Financing structure in the different currencies (namely variable rate percentage and duration) aligned with the characteristics of the assets, offering risk mitigation to interest rate hikes. 4 Regulation Risks related to legislative and regulatory changes that the group is obliged to comply with in the different geographies and markets in which it operates (namely sector packages, regulatory models, environmental legislation, taxes and other). Adverse regulatory changes could have a negative impact on the company's results  • High business diversification both geographically and in the energy value chain • Proactive management through careful monitoring and preparation of the several dossiers, as well as the adoption of a constructive and cooperative stance when discussing them, making it possible to anticipate and minimise the materialisation of options that are unsuited to the reality of the various market contexts in which the group operates. 5 Counterparty Risk associated with the potential default (or increase in relation to the expected level of default) of contractual obligations from customers, energy counterparties, financial counterparties (essentially associated with deposits with financial institutions and financial derivatives) and/or suppliers = • Diversification of counterparties, with limits on the concentration and percentage of exposures below Investment Grade • Careful analysis of counterparties, differentiating risk limits between counterparties, promoting contracts with those with the best credit quality • Continuous monitoring of the evolution of the credit quality of the group's counterparties • Use of counterparty risk mitigation instruments, such as financial guarantees, clearing and credit insurance • Implementation of credit risk premiums in contracts where the EDP group is a price-setter, differentiating between counterparties and compensating for Expected Losses. 6 Physical Assets under Construction Risk associated with Capex deviations and/or COD delay beyond what was estimated in the investment decision, leading to potential impacts on the current year (less revenue and more costs) and on the profitability of investments. This risk is mostly concentrated in Renewables investments due to the proportion of new investments foreseen in the Business Plan  • Timely contacting of equipment and EPC, to reduce the risk of cost increases or unavailability of the supply chain after commitments to projects have been made • Introduction of a buffer between the expected COD and the PPA start, to reduce the risk of incurring penalties or the need to purchase energy to fulfil the contract • Prudence in defining contingencies and assumptions of stress analysis (COD and CAPEX deviation) in the investment decision-making process. The quantification of EDP's risks is based on the potential loss in EBITDA, in a P95% scenario, estimated through the application of Monte Carlo simulations. Monte Carlo simulation, through the definition of probabilistic distributions for each risk factor/variable, allows to simulate possible future outcomes; for each simulation, different values are randomly generated for each of the probability distributions of the various risk variables (inputs). The result of a Monte Carlo simulation is a probability distribution, i.e., a representation of the different possible future outcomes and their probability of occurrence. In addition, EDP also makes a qualitative assessment of the potential financial impact and probability/likelihood of each risk, and the impact matrix for the main risks identified above is presented below. 

047 Part I Integrated Annual Report 2023 Performance | Risk Management EDP favours risk management based on quantitative analysis and continuous monitoring of the risks that may affect its business. For this purpose, the company regularly carries out sensitivity analyses of financial and non-financial risks, as well as analyses of stressed scenarios, using Monte Carlo analysis, or focusing on some specific stress scenarios. As an example, every year, when analysing the risk of the budget for the following year, EDP carries out a sensitivity analysis of various risk factors, namely renewable volume (hydro, wind and solar), electricity price, gas price, electricity demand, inflation, exchange rate, inflation rate, among other specific operational sensitivities, for the different markets which impact EDP's business. The impact on EDP's EBITDA of the variation in some risk factors is presented below, namely: • Hydro volume: a significant risk factor for EDP given its portfolio and high volatility of the variable, impacting the company's generation capacity. Assuming a price of €80/MWh, a 20% reduction in the expected volume impacts EDP's EBITDA by ≈€100M-€140M. It should be noted that EDP's financial performance in 1Q2022 was strongly impacted by the extreme drought in Portugal in the winter of 2021/2022 (≈-30% compared to the historical average hydro production) • Unavailability of assets: assuming an average 1% reduction in the availability of all EDP's generation assets (conventional and renewable), the impact on EDP would be ≈€30M-€50M. Also, in the process of evaluating risk in the budget exercise, as a way of assessing execution risk, stress analyses are carried out using Monte Carlo analysis. This type of analysis is applied to EBITDA, EBT, NI, FFO/ND and all relevant output variables at group level and broken down by platform, technology, BU, among others. In addition, liquidity/solvency stress analysis are also carried out to assess the company's ability to continue operating in a highly stressful situation, i.e., to maintain sufficient liquidity/cash levels to continue operating. Two different scenarios are considered (generalised liquidity crisis scenario for one year and EDP-specific stress scenario for two years), for which the company's ability to survive is assessed. EDP must have available liquidity, in cash and available credit lines, to cover these stress scenarios. A climate risk analysis exercise is also carried out every year using three different scenarios, which can be consulted in greater detail in section 2.3.7 Climate Risks. 

048 Part I Integrated Annual Report 2023 Performance | Risk Management 2.3.6 Emerging risks In addition to closely monitoring the main risks inherent to the group's activity, the main trends (at global and sectoral level) that may translate into threats and opportunities for the group are also comprehensively mapped, and appropriate mitigation strategies are proactively developed. In 2022, the mapping of emerging risks was updated, with an assessment by the EDP group's top, executive and non-executive, management. In 2023 the following stand out: (1) gap in labour market and risk of unavailability of talent for renewable energy companies; (2) disruptive technologies in energy sector; (3) geopolitics of global supply chains; (4) Introduction of Artificial Intelligence; (5) cybersecurity; and (6) increased climate risks and potential misalignment of international commitments for climate transition. Description Potential Impacts Mitigation Measures Social Risk Gap in labour market and risk of unavailability of talent for renewable energy companies The renewable energy sector is currently in a phase of rapid expansion, fuelled by a growing demand for clean energy solutions and government initiatives aimed at facilitating the transition to low-carbon economies. This increase in the renewable energy industry is expected to create a substantial demand for qualified professionals in various fields, such as engineering, project management, installation, and maintenance. At the same time, demographic trends indicate a projected decline in the working-age population in Europe, along with a stabilization in the United States. This demographic shift, along with a projected increase in the need for workers in renewable assets (which is expected to increase 3-4 times by 2030 in the EU), is set to result in a global shortage of skilled labour in the green economy, reaching 7 million by the year 2030, predominantly in the solar and wind sectors. This shortage of skilled labour represents a notable risk to EDP's business plan. The company has ambitious targets for the years 2023- 26, with the aim of deploying approximately 17 GW of additional renewable capacity, with an expected overall increase in the workforce of around 6%. Specifically, in the wind and solar sectors, a percentage increase in the number of employees of around 30% is expected. In the digital and innovation sectors, the expected increase in headcount is around 20%. • Increased competition in attracting and retaining talent, leading to more competitive and aggressive recruitment and retention strategies in the market • Companies, such as EDP, will need to become more involved in strategic workforce planning to identify critical roles, assess skills gaps, and implement measures to mitigate the impact of workforce shortages • Heavier investment in innovation and automation to reduce reliance on manual labour, streamline processes, and boost efficiency, as well as invest in research and development • Delayed project deadlines and risk of execution of the Business Plan • Increased global mobility of the workforce, attracting talent from regions where there is a surplus of qualified labour in the renewable energy sector, increasing global collaboration, and the diversity of the workforce • Significant investment in training and development programs to improve the skills of current employees and prepare them for roles in the renewable energy sector. • Implement a proactive and strategic global recruitment strategy to attract young, qualified professionals by creating internship and apprenticeship programs that offer first-hand experience to students interested in the renewable energy sector, fostering long-term relationships and retention, and more specific opportunities for experienced profiles • Develop and implement strategies to retain existing skilled workers, offering competitive compensation packages, providing career development opportunities, and cultivating a positive work environment to minimize turnover and enhance knowledge management • Conduct regular workforce needs assessments to identify critical roles and develop strategic learning plans to address skills gaps • Allocate resources to comprehensive training programs, focusing on upskilling and reskilling existing workers to prepare them for roles in the renewable energy sector through partnerships with educational institutions, companies in the sector, or other strategic partners • Promote a flexible, diverse, and inclusive workplace that welcomes and leverages the strengths of a diverse workforce, ensuring talent retention regardless of demographic or professional characteristics • EDP has been working on innovative projects within automation to overcome the labour shortage challenge and to increase efficiency. It also advocates for government and institutional support through policies, incentives, and funding to bolster workforce development efforts. Technological Risk Disruptive Technologies in energy sector The growing pressure to keep global warming to +1.5C by 2050 is attracting bigger than ever investments to clean energy technologies. In 2022, $1.4 trillion were invested in the energy transition. These large investment amounts are financing multiple types of technologies, some of which have low technology readiness levels, but high disruptive potential. Examples include carbon capture & removal, new geothermal energy, new nuclear energy (Small Modular Reactors and nuclear fusion), and geoengineering. EDP reinforced its investment of ≈€25B (gross investment 2023-26) in energy transition, with a strong focus on renewables and core low-risk markets (>50 GW of RES gross additions from 2021-30), and ESG excellence and future proof organization, being coal free by 2025, all green in 2030 and net zero by 2040. • If technological portfolio choices are not the most adequate, decrease in renewables' relevance in the future energy mix • Loss of revenue, as demand for renewable energy decreases • Decrease in the value of EDP’s renewable assets, creating stranded assets and impacting EDP’s financial performance, in a worst case scenario • Loss of EDP competitiveness in the energy sector • Damage to the company’s reputation and brand image. • Innovation and R&D are key priorities for EDP, conducting regular knowledge and technology assessments to evaluate the potential impact of emerging technologies on the business and to identify opportunities for innovation and growth • EDP regularly assesses existing and emerging technologies, which are incorporated into its innovation strategy that is reviewed periodically. EDP’s innovation strategy guides the technologies and opportunity spaces that will integrate EDP’s future portfolio and ensures alignment with latest market trends • EDP fosters a culture of innovation and partnerships with startups and incubators, particularly through acceleration programs such as the EDP Starter and Free Electrons. Moreover, EDP’s innovation teams help to disseminate a culture of innovation, with global initiatives that foster collaboration and intrapreneurship, for instance through The Spiral, our intrapreneurship program • EDP regularly monitors regulatory changes related to emerging technologies and engage with policymakers to advocate for policies that support innovation and mitigate regulatory risks 

049 Part I Integrated Annual Report 2023 Performance | Risk Management Description Potential Impacts Mitigation Measures • EDP has been diversifying its portfolio of assets to increase its resilience to emerging technologies, for instance with innovative projects in areas such as floating PV, offshore wind, hybridization projects of solar and wind, and utility-scale storage. Geopolitical Risk Geopolitics of global supply chains The supply and value chain obstacles for critical materials and electric components needed for renewable energy equipment supplies, which were thought to be temporary in the pandemic context, have proven to be a structural problem and have been further exacerbated by growing China-US tensions. China assumes a dominant position in the production of clean-energy technologies, accounting for ≈65% of the manufacturing capacity of most of the equipment and components needed for the energy transi- tion, leading to a high supply chain dependency for the rest of the world (for example, 97% of global solar wafers comes from China). Addition- ally, critical materials global reserves, mining and refining are highly geographically concentrated, which can become a geopolitical lever- age. • Shortage of equipment and components needed to deploy the 17 GW of renewables committed in 2023-26 Business Plan and/or maintain EDP’s new and/or existing projects • Impact to EDP's investment execution and financial performance through projects COD delays and cost and CAPEX increase • Loss of profitability due to the implementation of import tariffs for project supplies • Breach of existing and/or new agreements, due to failure to comply with agreed requirements (e.g., timings, maintenance, etc.) • Damage to EDP's reputation and brand image. • Supply chain and suppliers’ diversification at tier-N level • EDP regularly analyses and assesses supplier exposure to potential supply chain disruptions and monitors critical suppliers, as well as supplier diversification to reduce dependencies. Moreover, through innovation and R&D, the group explores new types of solutions to overcome supply chain issues, such as circularity options and/or new materials. • When applicable, evaluate the trade-off of extending ongoing contracts vs. new bids/anticipating purchases to cover shortages and price increases • Evaluate and improve /transform EDP’s inventory management strategies • Analyse and implement new partnerships with current /new suppliers. EDP maintains close connection with the players acting in the energy ecosystem, including startups with innovative products or services, with which pilot projects are organised whenever a fit exists with EDP needs. Technological Risk Introduction of Artificial Intelligence (AI) The introduction of AI tools into the corporate landscape presents a double-edged sword, offering tremendous potential for automation, efficiency, and innovation while simultaneously posing inherent risks that could threaten EDP’s future trajectory. As AI automates tasks and evolves skill requirements, a prime concern is that employees will face the dual perils of job displacement and obsolescence, jeopardizing their security and adaptability. Moreover, AI systems may handle vast amounts of sensitive data raising concerns about data privacy and security. Furthermore, AI systems are susceptible to biases that can permeate their decision- making, leading to discrimination against certain groups of people. Finally, the complexity of AI systems often makes it difficult to comprehend their decision-making processes, hindering accountability for any errors or unintended consequences. Several regulatory approaches to legislate AI are as of early 2024 in nonbinding principle (Singapore, United States) or being finalized (European Union). • Legal charges for not complying with new developments in the AI legislation, across the various countries under which it operates. Fines from legal enforcement could represent up to 7% of annual global revenues, according to regulation proposed by the EU • Loss of EDP market share and/or competitiveness due to slow adoption of AI • Increased costs associated with required investment in data security and compliance • Damage to EDP’s reputation and consumer trust due to data breaches and discrimination scandals involving AI • Loss of competitiveness due to leak of confidential information, namely commercially sensitive and/or advantageous information • Compromise of personal data with impact on data subjects (employees, clients, vendors, and other third-parties). • Ensure transparency in AI usage within EDP by creating a taxonomy and inventory of models, classifying them in accordance with regulation, and recording all usage across the organization in a central repository • Create detailed documentation of AI usage, its functioning, risks, and controls, and clear documentation on how a model was developed and what is its intended use • Implement a governance structure for AI that ensures sufficient oversight, authority, and accountability both within the organization and with third parties and regulators • Establish clear data governance policies that protect privacy and ensure that data is used responsibly • Implement bias detection and mitigation measures to identify and address biases in EDP’s AI systems • Investment in training and development to ensure that EDP’s employees have the necessary skills and knowledge to work effectively with AI systems • Continue the digital talks and clinics initiatives that are online interactive sessions aiming to increase knowledge in digital topics, namely AI • Limit the use of AI platforms to a controlled (exclusive tenant), scope limited and secure environment, monitored by EDP. Technological Risk Cybersecurity EDP, as an energy utility company, has become very reliant on its digital infrastructure for efficient operations and services delivery. However, this increase in technological sophistication and integration also leads to an increased exposure to cyber risks of different natures. EDP is already driving a digital transformation to further boost business performance with a total of ≈€2B in digital TOTEX (for 2023-26 period), in which cyber resilience is included. Despite all the efforts made by organizations, there is probable risk that cyber-attacks become more frequent and with higher magnitude. • Losses from critical EDP systems unavailability (dispatch/plants, billing, customer service) • In an extreme case, damage/destruction to physical assets and lives • Data breach /loss (personal and others) • Fines due to GDPR violations • Increased costs associated with increase in cybersecurity investment • Damage to EDP’s reputation in case of a cyber-attack that impacts power availability or data privacy. • Cyber Governance at EDP with strong support from the Board • Continuous improvement of the security of internal systems • Continuous improvement of dedicated Security Operations Centre (SOC) for continuous security monitoring of the group's IT & OT infrastructure • Continuous improvement and development of dedicated EDP Cyber-range training scenarios for simulation and testing of cyber attacks • Online training and awareness actions on information security principles, seeking to enlarge training audiences • Continue digital talks and clinics initiatives (online interactive sessions) to increase knowledge in digital topics, namely cybersecurity • Continue to integrate national and international work/study groups (e.g., CRT.PT, Word Economic Forum, Cyber DSO group, International Energy Agency), and European projects. 

050 Part I Integrated Annual Report 2023 Performance | Risk Management Description Potential Impacts Mitigation Measures EDP Global SOC is also seeking membership within Trusted Introducer, which is an European forum focused on cooperation and coordination of CSIRTs and general good practices in information security. • Continue to monitor cybersecurity Bitsight rating (2022 value already reached 2025 target, and is maintained during 2023) • Continue to address cybersecurity topics in the Cyber Executive Committee, with attendance of BU’s management, the Chief Information Security Officer (CISO), Chief Risk Officer (CRO) and an EBD member • Cyber risk insurance. Environmental Risk Increased climate risks and potential misalignment of international commitments for climate transition Physical risks associated with climate change (e.g., chronic risks such as increased temperature or reduced precipitation, and acute risks such as extreme temperature and precipitation events) impacting portfolio availability, generation output and increasing costs. Risk of political misalignment with a global climate transition strategy (due to the influence of other factors with greater relevance at the level of each State, namely favouring social policies), jeopardizing long term decarbonization objectives. To accelerate its energy transition, EDP has committed investment in energy transition of ≈€25B in 2023-26. EDP carries out an annual assessment of climate risks and opportunities until 2050, which is described in the following section. • Structural loss of portfolio profitability due to damage to physical assets and loss of revenue caused by more frequent extreme weather events and increase in overall costs (such as insurance) • Reduction in hydro portfolio profitability in case of a structural reduction in precipitation • Limitation of the economic potential of investments in new technological solutions in case of misalignment towards a green economy (e.g., green hydrogen with 1.5 GW of installed capacity expected by 2030). • Continue structured assessment of climate risks (TCFD), updating scenarios, evolution of climate variables and key risks and opportunities for each business • Continue the development of climate adaptation plans by Business Unit in line with the main risks identified • Integration of climate risk assessment into investment analysis • Close monitoring of national and international commitments in decarbonization and adjustment of EDP's strategy accordingly • Geographic, technological and business line diversification (€25B gross investment in 2023-26, of which ≈85% in renewables, clients and energy management and ≈15% in electricity networks; ≈40% North America, ≈40% Europe, ≈15% South America and >5% APAC). 

051 Part I Integrated Annual Report 2023 Performance | Risk Management 2.3.7 Climate risks 2.3.7.1. Introduction In 2017, the TCFD (Task Force on Climate-related Financial Disclosures) issued a set of recommendations on how to analyse, report and incorporate the climate transition to increase transparency and climate-related information. The EDP group has adopted these recommendations and in 2021 launched a project to deepen them, including a diagnosis to identify points for improvement and the creation of an annual process to assess climate risks and opportunities. More detailed information on the TCFD recommendations, governance model and resilience strategy are available on EDP's website: EDP Climate Transition Plan | edp.com. EDP has in place an internal climate risk management governance model, integrated into the global risk management process, to annually review and report on the resilience of EDP's strategy to climate change. The process is overseen by the Risk Global Unit and the Sustainability Global Unit, with the collaboration of the Energy Planning Global Unit, and supported by a team of specialised interlocutors from the different Business Units (risk officers, sustainability officers and energy planning areas). The process is structured in three distinct phases: 2.3.7.2. Climate Risk Management Process 2.3.7.3. EDP's Climate Risk in 2023 After validating the taxonomy, three climate scenarios were defined that aggregate the physical and the transition scenarios. Climate scenarios Considering a 30-year horizon and for the different scenarios defined, narratives focussing on the various dimensions (social, regulatory, and political, economic and technological, and energy) were constructed and are presented below: Physical scenarios: • RCP 2.6: considers (1) compliance with the Paris Agreement; (2) that the energy system reaches carbon neutrality by 2070; (3) that the temperature rises between 1.5˚C and 2˚C; and (4) that the average sea level rises by 0.4m and ocean acidification begins to recover by 2050 • RCP 4.5: considers that (1) the Paris Agreement is not fulfilled; (2) the temperature rises between 2˚C and 3˚C and extreme temperatures become more frequent; and (3) the sea level rises by 0.5m and many species are unable to adapt 

052 Part I Integrated Annual Report 2023 Performance | Risk Management • RCP 8.5: considers that (1) the Paris Agreement is not fulfilled; (2) the temperature rises by more than 3˚C; (3) extreme events become more frequent and there are large variations in rainfall; and (4) the sea level rises by 0.7 metres. Transition scenarios: • Net Zero Emissions by 2050 Scenario (NZE) with internal adjustments: considers (1) the global energy sector reaching net zero CO2 emissions by 2050; (2) economic growth and job creation related to sustainable energy; (3) a more resilient and cleaner energy system; and (4) full international co-operation for sustainable development • Base Scenario: assumes that (1) the announced policies are generally complied with, and no additional effort is made towards sustainable development; and (2) policies, albeit limited, are adopted to reduce the use of fossil fuels, but demand is still high. For more detailed information on the physical and transition variables considered, please consult the EDP Climate Transition Plan | edp.com. The evolution of the physical variables was provided by a specialised external consultant, using the Copernicus database and other international databases. The transition variables, namely the evolution of prices, energy demand and energy mix, are based on scenarios from the IEA and other international sources (e.g., Aurora, Baringa, among others), with the necessary adaptations to the countries where EDP is present. Quantification, based on the individual analysis of the impact on EBITDA of each risk and opportunity (physical and transition), is carried out by each Business Unit and for each geography. This quantification considers the identification of the physical variables and their evolution according to the experts, and the political/social/economic/technological narratives related to the different scenarios. The quantification method depends on each risk and opportunity using, whenever possible, the direct method (expected loss/gain and maximum loss/gain at P95%) or, alternatively, the indirect method (probability/frequency, average impact and maximum impact at P95%). For the purposes of the group's analysis, the consolidation of losses and gains is carried out considering correlations among risks and opportunities and among geographies. Short-term risk (5 to 10 years, specifically 2025 and 2030) is mainly related to transition risks, namely energy market design, prices, regulatory framework, and technological developments. Long-term risk (10 to 30 years, specifically 2030 and 2050) is mainly related to physical risks that may affect EDP's asset portfolio, namely regarding extreme temperatures, extreme wind and rain events, and structural changes in physical parameters. The following table shows, for 2050, the potential impact on the EDP group of the relevant physical risks (maximum loss P95%) and opportunities (minimum gain P5%) (chronic and acute), considering the physical scenarios RCP 2.6 and RCP 8.5 and relating them to the mitigation measures in place.

061 Part I Integrated Annual Report 2023 Performance | Business area analysis 3.1. Business area analysis 3.1.1. Renewables, Clients and Energy Management Financial Analysis Renewables, Clients and Energy Management EBITDA (Wind & Solar generation plus Hydro, Client Solutions and Energy Management activity) increased 18% vs. 2022 to 3,552 million euros, supported by: • Wind and solar EBITDA decreased to 1,835 million euros in December 2023 despite higher capital gains, reflecting: (i) lower avg. selling price (-6% YoY), mitigated by higher generation output (+4% YoY) mainly driven by higher average MW installed (+8% YoY) and (ii) lower contribution from Ocean Winds. • EBITDA from Hydro, Client solutions and Energy Management (hydro and thermal generation, supply and energy management), increased to 1,718 million euros detailed by: • In Iberia: EBITDA increased to 1,480 million euros, with 2023 figures including an extraordinary gain of 104 million euros, resulting from the 50/50 partnership signed to convert Aboño into a gas-fired plant. Besides this extraordinary gain, YoY increase reflects a strong rebound from a very weak 2022 that was penalized by a record- high prices and the driest winter period since 1930 that heavily penalized intermediation costs. In more detail: (i) Hydro production benefited from a normalization of hydro resources specially during the first quarter of the year, (ii) normalization of energy management activities in a context of declining commodity prices, which contrasts with a 2022 with extremely high intermediation costs and (iii) recovery of supply activities when compared with a very harsh environment in 2022. These effects partially compensated the decrease in thermal production (54% • YoY) and the booking of 1.2% revenue tax in Spain (45 million euros already recorded in 1Q23). • In Brazil, 238 million euros EBITDA, with the segment performance being penalized by: i) sale of Pecém in December 2023 (-84 million euros) and ii) deconsolidation of hydro plant Mascarenhas (“Energest”) in December 2022. Operational Analysis Wind and Solar Generation • The Group's wind and solar generation portfolio corresponds to a total of 16.6 GW of installed capacity (EBITDA + Equity), an increase of 1.8 GW (+12%) explained by the growth of the portfolio of EDP Renováveis (“EDPR”) net of deconsolidations resulting from the asset rotation strategy. • In 2023, EDPR added a total of 2.5 GW, including the acquisition of a wind portfolio in Spain (45 MW). • Regarding the EBITDA portfolio, EDPR added: i) 958 MW of onshore wind technology: 277 MW in Europe (65 MW in Spain, 12 MW in Poland, 117 MW in Italy, 35 MW in Greece, 26 MW in France and 22 MW in Portugal), 297 MW in Canada, 202 MW in the United States, EBITDA Renewables, Clients and Energy Management €3,552M +18% vs. 2022 

062 Part I Integrated Annual Report 2023 Performance | Business area analysis 99 MW in Brazil and 83 MW in Chile; ii) 1,300 MW of solar PV technology: 589 MW in the United States, 498 MW in Europe (195 MW in Poland, 66 MW in Spain, 223 MW in Portugal, 9 MW in Netherlands, 4 MW in France) and 212 MW in Brazil; iii) 251 MW of solar DG technology: 63 MW in the United States and 190 MW in APAC (9 MW in Vietnam, 85 MW in Singapore, 79 MW in China, 11 MW in Taiwan and 6 MW in Thailand); iv) 15 MW of storage technology in the United States. • Following the asset rotation strategy, EDPR concluded the following sales: a 256 MW in Spain, 142 MW in Poland and 260 MW in Brazil wind onshore portfolios. Regarding the equity portfolio, the variation was -35 MW resulting from a stake in San Cristo de Magallón and San Juan Bargas and +1 MW of solar DG technology in APAC. • Wind and solar generation increased 4% YoY, as a result of higher installed capacity (+12%), which was mitigated by: i) concentration of annual capacity additions in 4Q23, ii) wind resources below LT average in the United States related to El Niño, iii) increase of solar capacity weight, with lower load factors vs wind, iv) asset rotations closed in 3Q23 for wind assets in Europe (Spain and Poland). • At the end of 2023, EDPR had 4.4 GW of capacity under construction, of which 0.9 GW related to onshore wind, 2.8 GW solar and 0.7 GW offshore wind. Regarding onshore wind, 90 MW in Europe (20 MW in Spain and 70 MW in Greece), 329 MW in Brazil and 504 MW in Colombia. Solar projects respect to 404 MW in Europe (140 MW in Spain, 15 MW in France, 155 MW in Italy, 21 MW in Netherlands and 74 MW in Hungary), 2,074 MW in the United States, 255 MW in Brazil and 65 MW in APAC (31 MW in Singapore, 25 MW in China, 8 MW in Taiwan and 1 MW in Malaysia). On wind offshore, 419 MW in the United Kingdom and 309 MW in France. Hydro Generation Iberia • EDP's hydro production portfolio in the Iberia includes a total of 5.5GW of installed capacity, of which 43% includes pumping. • Hydro generation in 2023 increased 62% year on year (+3.8TWh), to 9.8TWh, reflecting the above average hydro reservoir levels in Portugal, with hydro generation coefficient of 0.99 in Portugal, compared with a coefficient of 0.63 in 2022. Brazil • The Hydro generation portfolio in Brazil includes a total of 1.4 GW of installed capacity. The portfolio also includes 0.6 GW of equity installed capacity (Jari, Cachoeira-Caldeirão and S. Manoel). • In 2023, the average GSF stayed at 90% registering an increase of 4% vs 2022. Consequently, the volume of energy production, considering the consolidated companies, was 4,294 GWh, a decrease of -25% year-on-year. Risk outlook • Renewable generation volumes: uncertainty regarding hydro generation levels, with high volatility, being 2022 an example of a year with very low production in the Iberian Peninsula; uncertainty regarding the remaining technologies with less annual volatility in a normal scenario, but which could be strongly affected by extreme meteorological scenarios (e.g., El Niño in 2023). • Prices of PPAs: price reduction trend due to increased competitiveness (auctions and Corporate PPAs) and reduction in the cost of raw materials and equipment. • Prices for generation to market: high volatility of market prices (albeit with lower base values), including electricity prices, green certificates, and RECs (Renewable Energy Credits). • Policy/ regulatory support for renewables: uncertainty regarding long-term regulatory frameworks (i.e., incentives, capacity, among others), as well as potential clawbacks to inframarginal technologies. • Political/ social risk in EDP geographies: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing in recent years (although progressively decreasing since the 2022 presidential elections). 

063 Part I Integrated Annual Report 2023 Performance | Business area analysis • Counterparty: possibility of counterparties defaulting on their obligations (i.e., energy sales contracts, equipment purchase contracts, among others). • Interest rates and capital gains: increased volatility of reference interest rates, impacting the expected profitability of new investments and impacting the lower-than-expected selling price of parks for some projects, leading to lower capital gains. • Inflation: uncertainty regarding the evolution of inflation in the different geographies, with an impact mainly on the costs (Capex and Opex) of operational projects and new projects. • FX: potential evolution of key currencies leading to lower results in EUR. • Construction and asset development: delays in the allocation of construction permits and potential capex deviations and delays in the commissioning date, due to supply chain related constraints and cost increases. • Asset operation and availability: uncertainty regarding damage of assets and/ or loss of profit, risk of delays in maintenance and construction due to logistical and supply chain constraints. Operational Analysis Thermal Generation Iberia • The Iberian thermal generation portfolio has an installed capacity of 4 GW, with most of the capacity being CCGT (73% or 2.9 GW) and coal (23% or 0.9 GW). The remaining thermal capacity is divided between nuclear, cogeneration and waste (0.2 GW). • Thermal generation decreased 50% compared to 2021 (-8.6 TWh), to 8.6TWh, following the disposal of 80% of the 720 MW Pecém coal plant in Brazil in December, and the new 50%/50% partnership in Aboño Coal Plant in Spain (deconsolidated in December 2023), as well as hydro recovery. Nuclear generation remained stable. Brazil • In Brazil, 80% of Pecém plant was sold in December, therefore there is no thermal installed capacity in 2023. • Pecém was dispatched during the 4Q23 with an output energy of 61 GWh due to the heat waves of November and December. • Pecém's availability stayed at 99%. Supply 

064 Part I Integrated Annual Report 2023 Performance | Business area analysis Europe • 2023 marked a more stable context but still challenging in the commercialization of energy-related products and services, mostly as a consequence of the price increase in 2022\. Wholesale energy and commodities prices soared during 2022 in response to gas supply shortage due to Ukraine-Russian conflict and sanctions taken by Western counties against Russian gas supply, which led to all-time high inflation levels in energy products and services. • In this context, the already in place Energy Transition plans were fast paced worldwide with countries and companies committing to more ambitious Net Zero targets, which resulted in higher prices and supply chain disruptions. These decisions affected directly prices and supply of solar panels and Electric Charges to face a higher demand of customers looking for green solutions and energy independence. • In Portugal the regulated electricity business (operated by EDP under SU Electricidade brand) decreased 5% vs 2022 in number of clients to 927 thousand, while electricity sold increased 7% to 3 TWh. • In the liberalized electricity business in Portugal, EDP saw a 4% reduction in number of clients to 3.8 million, and a reduction of 4% in the volumes sold to 17 TWh. The liberalized gas business lost competitiveness, and therefore EDP portfolio of gas customers in Portugal reduced by 13% to 480 thousand, and volumes sold decreased by 38% to 3.2 TWh. • In Spain, EDP also registered a decrease of 23% in electricity sold to 9.5 TWh and a decrease of 25% in gas volume sold to 2.5TWh. • In the services sector, among the main traditional services, emphasis should be placed on “Funciona” portfolio, which grew by 1% bs 2022 to 599 thousand customers and “EDP Saúde”, which registered a total number of 236 thousand customers in Portugal, 9% more than in 2022. • The commitment and the focus on to new services more focused on efficiency and energy transition remain, EDP positions itself as a brand that looks for offering to all its clients (residential, small and medium-sized companies, large business groups, and government entities) solutions that allow energetic autonomy and independence.Hence, solar DG and Electric Mobility are the present bet thinking about the future. In Iberia, EDP is proud of having installed 189MWac of solar DG and 2,3 thousand chargers both public and private. • Regarding the ambition of geographical expansion, EDP has been investing in companies providing service related to solar DG, with the purchase of Enertel (Italy) in 2021, Soon Energy and Zielona (Poland) in 2022, and Enerdeal (Belgium and Luxembourg) in 2023. Therefore, during 2023 EDP installed 106 MWac in these countries. Brazil • The total volume of energy sold in 2023 increased by 20% to 39.7 TWh. • The focus on solar DG is also a reality in EDP Brazil, with 48 MWac installed in 2023. Although being the geography most affect by the delays in the installations, a recover is expected in 2024. Risk outlook • Market price: high volatility of market prices (albeit with lower base values), including electricity prices, as well as fuel prices with an impact on the Energy Management activity. Potential differences in electricity and gas hedges in indices other than the original exposure (both gas and electricity) with basis risk (especially relevant in cases of energy crisis). • Risk on thermal revenue: possibility of a fall in thermal generation spreads. • Retail margin/ market share: uncertainty regarding the evolution of retail margin or loss of market share, marketing of new products and services and potential deviations in demand vs. energy previously contracted. • Political/ social risk in EDP geographies: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing in recent years (although progressively decreasing since the 2022 presidential elections). • Counterparty: possibility of counterparties defaulting on their obligations (i.e., energy sales contracts, energy purchase contracts, equipment purchase contracts, among others). • Operation and availability of assets: uncertainty regarding damage to assets and/or loss of profits, risk of delays in maintenance and construction due to logistical and supply chain constraints. • Liquidity risk: the risk of a sudden increase in liquidity needs (e.g., margin calls) that may exceed current sources of funding. Liquidity risk increased significantly with the energy crisis in Europe, however, in recent months it has shown a downward trend, associated with the reduction in market prices. 

065 Part I Integrated Annual Report 2023 Performance | Business area analysis 3.1.2. Networks Financial Analysis • EBITDA from networks remained flat vs 2022 at 1,501 million euros, mainly explained by: (i) 6 million euros increase in the Brazilian networks segment mainly due to tariff update in 2023 and higher RAP, mitigated by higher operating costs as result of higher inflation in the period which also reflect on distribution remuneration; (ii) 9 million euros decrease in Spain following the increase in Opex due to higher personnel costs. • In Iberia, EBITDA was broadly stable compared to 2022 as the positive impact from higher Portuguese 10Y bond yields on the return on RAB and the benefits from integration of Viesgo were compensated by an increase in OPEX, mainly reflecting the high inflation environment. Operational Analysis Distribution Iberia • The Distribution network in Iberia reached the length of 287,516 km in 2023 corresponding to a slight increase of 1% vs 2022. • At the end of 2023, EDP reached 7.0 million smart meters installed in the entire distribution network in the Iberian Peninsula. Smart meters are aligned with the efficiency, digitalization and innovation strategies and are considered a strong bet in the Group, especially in Portugal where there was an increase of 22% against 2022. • In 2023 the volume of electricity distributed in Iberia remained equal to 2022. • The Installed Capacity Equivalent Interruption Time (ICEIT) in Portugal registered a decrease vs 2022, reaching the value of 48 minutes, which is still below the regulator’s benchmark. In Spain, the registered ICEIT value was of 19 minutes, an increase from the previous year’s value of 18 minutes. • Regarding energy losses in the network, Portugal registered a decrease in the indicator (measured based on energy input into the grid) which reached 7.8% in 2023 (-0.9pp vs 2022), remaining below the upper regulatory limit of 9.00%. In Spain (measured based on energy input into the grid), losses stayed at 4.8% (-1.1pp vs 2022). Brazil • The Distribution network in Brazil reached the length of 96,999 km in 2023, corresponding to an increase of 1% vs 2022. • In 2023, the volume of energy distributed increased 4.9%, (2.7% at EDP SP and 8.3% at EDP ES). This reflects the increase in the number of connected costumers and the heat waves during the months of November and December. • The number of new customers increased 3% with free customers increasing by 16.5% ( 153 customers at EDP SP and 159 customers at EDP ES), due to the migration of captive customers to the free market. • Regarding service quality indicators, both distribution companies show a slight worsening (vs 2022) of the Equivalent Duration of Interruption (DEC) with the values staying at 369 minutes for EDP SP and 437 minutes for EDP ES. As for Equivalent Frequency of Interruption (FEC), there was an improvement vs the previous year, with the values reaching 2.9 in EDP SP and 3.1 in EDP ES. • As for energy losses in the network, both distribution companies showed improvements with EDP SP reaching a value of 7.2% (-0.7p.p. vs 2022) and EDP ES reaching 11.8% (- 0.1p.p. vs 2022). Transmission Brazil • In 2023, EDP Brazil concluded the sale of two transmission lines (EDP Transmissão SP-MG and Mata Grande Transmissão de Energia). EBITDA Networks €1,501M -0.3% vs. 2022 

066 Part I Integrated Annual Report 2023 Performance | Business area analysis • The construction of Lote 02 and at the end of the year 91% of the Lote EDP Transmissão Norte (Lote 1) was built. • In 2023 there was the conclusion of all reinforcement and improvement licencing of 2023 and anticipation of 2024 in EDP Goiás, with an additional margin of 59% - R$37Bn in Xavantes and 32% R$13Bn in Itapaci. Risk Outlook • Low voltage network concessions (Portugal): uncertainty as to the timing of the launch of the tender and its terms, with possible fragmentation of the activity and possible increased costs for the system. • Political/ social risk: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing in recent years (although progressively decreasing since the 2022 presidential elections). • Counterparty: possibility of default or failure of counterparties to meet their obligations, leading to possible delays, penalties or lost revenue. • Construction and asset development: delays in the allocation of construction permits and potential capex deviations and delays in the commissioning date due to supply chain related constraints and cost increases. • Asset operation and availability: uncertainty regarding damage of assets; risk of delays in maintenance and construction due to logistical and supply chain constraints. • Business continuity: impact of extreme events with possible materialization in a prolonged interruption of operations.

Excluding non-recurrent effects Recurrent EBITDA increased 11% to 5,023 million euros, benefitting from a strong growth of Hydro, Clients & Energy Management in Iberia. • Renewables, Clients and Energy Management EBITDA increased 18% vs. 2022 to 3,552 million euros. On EDPR, EBITDA decreased to 1,835 million euros in December 2023 despite higher capital gains, reflecting: (i) lower avg. selling price (-6% YoY), mitigated by higher generation output (+4% YoY) mainly driven by higher average MWs installed (+8% YoY) and (ii) lower contribution from Ocean Winds. Hydro, Clients & Energy Management Iberia EBITDA increased to 1,480 million euros in 2023 mainly reflecting a recovery of hydro resources in 2023 vs. the extreme drought of 2022\. Hydro, Clients & Energy Management Brazil EBITDA in 2023 decreased 95 million euros YoY to 238 million euros mainly driven by the deconsolidation of the Mascarenhas Hydro Plant (“Energest”) that took place in December 2022. • Eletricity Networks EBITDA slightly decreased to 1,501 million euros in 2023. In Brazil EBITDA was flat YoY, mainly driven by (i) tariff update in transmission 2023 and higher RAP given the completion of reinforcement works in Lot Q and EDP Goiás and (ii) over contracting costs in distribution. EBITDA in Iberia was slightly down YoY, mainly influenced by the high inflation environment, leading to an increase in operating costs. EBITDA €5,020M 11% vs. 2022 

068 Part I Integrated Annual Report 2023 Performance | Share performance • Opex costs increased 6% vs. 2022 to 1,995 million euros due to inflation, the tight cost control and successful implementation of ongoing saving programs avoided a higher increase. • Other net operating revenues/(costs) decreased to -59 million euros, explained by increased costs with rents on distribution and the windfall profit tax in Spain. • EBIT increased 11% vs. 2022 to 2,798 million euros, reflecting the increase in the operational performance. • Net Financial results remained flat at -910 million euros in 2023. On one hand, the average cost of debt increased to 5% YoY, penalized by all currencies, essentially by EUR and USD higher interest rate environment. This effect was mitigated by an increase in capitalized financial costs. Net foreign exchange was positively impacted by 37 million euros from the settlement of US dollar pre-hedge as a result of the revision of our funding strategy by currency. • Income taxes amounted to 507 million euros, representing an effective tax rate of 27% in 2023. • Non-controlling interests decreased 23% to 379 million euros in 2023, including (i) 295 million euros related to EDPR (-67 million euros year-on-year), explained by the lower operational performance and the impact of Colombia impairment; (ii) €57 million euros related to EDP Brasil, reflecting the acquisition of all minorities at EDP Brasil holding level in 3Q23 (+48 million euros positive impact on EDP net profit in 2023). • Net profit attributable to EDP shareholders reached 952 million euros in 2023 (+40% vs. 2022), driven by normalization of hydro resources and better results from energy management. Moreover, EDP successfully concluded the full acquisition of EDP Brasil's minority interests, which also contributed to an improvement in EDP's net profit in 2023.

Share EDP market price was 4.555€ per share at the end of 2023, 2.2% below the 4.656€ per share at the end of 2022. Based on the payment of dividends to shareholders held on April 12 th , 2023 (0.19€ per share), which implied a dividend yield of 4.2% (considering 2023’s year-end closing price), in 2023 EDP generated a total shareholder return (TSR) of 1.5%, assuming automatic reinvestment of the dividends received into new shares. 3.3.2. Market Performance In 2023, European Equities benchmark index, Eurostoxx 600, yielded a positive TSR of 19.5% as stocks rallied and bonds recovered after suffered substantial losses at the onset of the year due to concerns about a recession faced last year. The year 2022 was significantly impacted by geopolitical tensions stemming from the invasion of Ukraine, resulting in an unprecedented energy and food crisis that reverberated across much of the globe. Additionally, the performance of European shares in the early months of 2023 was influenced by global market challenges, particularly the abrupt downfall of Swiss lender Credit Suisse and the struggles faced by U.S. mid-sized lender Silicon Valley Bank. These anxieties were subsequently alleviated as investors’ confidence grew, propelled by a noteworthy shift in expectations for interest rate reductions by the commencement of 2024\. The Utilities Sector underperformed the Eurostoxx600 and exhibited total return of 17.7% in 2023, in contrast to the challenges faced in 2022, where energy markets were adversely affected by rising energy sourcing costs. Despite the difficulties encountered by renewables players throughout the year, government policies persist in bolstering the performance of electricity markets, thereby promoting the ongoing energy transition. Moreover, the reduction in interest rates for 2024 is anticipated to contribute to a recovery in energy market stocks. In 2023, the global benchmark for clean energy-related businesses, S&P Global Clean Energy Index, registered a TSR of -20.1%, mainly attributed to the underperformance of pure renewables companies compared to utilities, resulting from profit warnings prompted by high interest rates, operational challenges, and disruptions in the supply chain. Consequently, a wave of impairments affected renewable energy players, precipitating a subsequent decline in the clean energy stock market. EDP’s TSR of +1.5% in 2023 underperformed both European and Utilities benchmark Indexes, impacted by lower resources caused by weather conditions and capacity delays. The performance benefits from strong performance of integrated portfolio in Iberia following hydro recovery and better sourcing costs. 3.3.3. Factors influencing the change in EDP share price The performance of EDP’s share price in 2023 was impacted by several factors. On one hand, the adverse of macroeconomic conditions resulting from the increase in interest rates, supply chain issues and complicated weather condition. On the other hand, the implementation and strong delivery of EDP’s Strategic Plan growth targets in the first year of this plan. 60% 70% 80% 90% 100% 110% 120% 130% Dec-22 Jan-23 Feb-23 Mar-23 Apr-23 May-23 Jun-23 Jul-23 Aug-23 Sep-23 Oct-23 Nov-23 Dec-23 Total Shareholder Return EDP EUROSTOXX UTILITIES EUROSTOXX 600 S&P Clean Energy Index

Climate action approach Prominently positioned at the forefront of energy transition, EDP recognises the importance of the electricity sector, and of its contribution to a low-carbon economy, as part of the solution for tackling climate change. Given the current context of climate emergency, as well as compliance with the global commitment established by the Paris Agreement and reinforced by the Glasgow Pact to limit the increase in global average temperature to 1.5˚C, EDP's contribution to combating climate change is realised through its Climate Action approach, embodied in the Climate Transition Plan (published in an autonomous document in 2023). EDP's Climate Action approach focuses on mitigation actions - with the aim of reducing greenhouse gas (GHG) emissions and adopting climate change adaptation plans in all regions and business units exposed to significant climate risks. These actions are supported in a crosscutting way by innovation - which aims to promote the development of carbon-neutral technologies and increase energy efficiency; and by capacity building, increasing awareness and transparency on climate change, both within and outside EDP. This approach is the responsibility of corporate governance, which assumes a strategic role in the appropriate management of climate responsibilities and action plans, where it includes the identification, analysis and management of climate-related risks and opportunities (more details in Climate Transition Plan). EDP has publicly assumed a set of near and long-term objectives and targets that support its decarbonisation strategy, approved by the Science Based Target initiative (SBTi), as being aligned with a decarbonisation trajectory of 1.5˚C. Under the new SBTi Net-Zero standard, EDP has also committed to achieve Net-Zero by 2040 across its value chain, covering scope 1, 2 and 3 emissions, from a baseline year set for 2020. Despite ongoing efforts to reduce GHG emissions, there are residual emissions that cannot be eliminated. For these emissions, EDP will offset them using carbon credits. The following emission reduction targets were validated and approved by SBTi in 2023: Scope Target 2030 Target 2040 2023 vs. 2020 S1+S2 [intensity] -95% -96% -48.6% S3 [absolute] -45% -90% -16.0% S1+S3C3 [intensity] -80% -95% -47.3% S3C11 [absolute] -45% -90% -57.1% S1+S2+S3 [absolute] \- -90% -35.2% EDP follows the recommendations of the TCFD (Task Force on Climate-related Financial Disclosures), disclosing information on governance, strategy, risk and opportunity analysis, metrics and targets and financial impact of climate change on the company (more details in Climate Transition Plan). The EDP group publicly discloses its response to the CDP Climate Change questionnaire, in which it details its strategy and performance in the fight against climate change in line with the TCFD (CDP Climate Change EDP 2023) In 2023, EDP achieved again the highest level of this index (Leadership A) in the CDP Climate Change, which has been secured since 2015. Climate Transition Plan progress In 2023 EDP published its Climate Transition Plan, built upon the 2022 Commitment to Climate Transition and the results of the Net Zero Acceleration Taskforce, and approved at 2023 Annual General Meeting, supported by strong shareholders vote of over 90%. The Board engagement and the Say on Climate from shareholders brings consistency and credibility to the path to follow. EDP is being recognized as front runner in credibility of its transition plan: i) was the only corporate selected to speak at the Credibility session of the UN Climate Ambition Summit convened by UN Secretary General, September 2023, to showcase first “movers and doers” and ii) was invited by CDP showcase its climate transition plan among recognized corporate standards, companies, and financial institutions. The Climate Transition Plan sets a baseline of EDP's strategy for this decade, supported mainly by the Business Plan 23-26 under a broader pathway for a net zero goal in 2040. 

078 Part I Integrated Annual Report 2023 Performance | Sustainability EDP’s climate pathway is set on an action plan that provides the strategy to decarbonise towards science-based Net-Zero targets. EDP will review this Plan in each Business Plan Cycle. In the meanwhile, the progress towards targets achievement based on EDP’s mitigation actions, mainly impacting carbon footprint and evolution of emissions reductions and corresponding Net-Zero targets, are reported on the document Climate Transition Plan: Progress report, 2023. Further information can be found in Climate Transition Plan. Mitigation Mitigation is directly linked to EDP's Business Plans, both on the supply side and on the demand side, with the aim of reducing global GHG emissions by implementing solutions based on four main pillars: In 2023, compared to 2022, the first and second pillars were strongly influenced by: • favourable hydro conditions in the Iberian Peninsula (productivity index close to the average year), after a 2022 of extreme drought, which led to a higher hydropower generation and a lower operation of the CCGT plants • the sharp reduction in production from coal-fired power plants in Spain, combined with the announced plans for the Spanish thermal assets: • to convert Aboño II from coal into gas fired, expected to occur by middle of 2025 while continuing to co-fire blast furnace gases, a case study of circular economy in Europe through the valorisation of this by-product, avoiding the emission of one million tons of CO2/year • establishment of a new partnership with the Asturian based industrial group Corporación Masaveu, S.A. (“CM”), through the sale of a 50% stake in Aboño • authorization requested from the electricity system operator (Red Eléctrica) to close Aboño I coal plant, as well as EDP’s last remaining coal plants in Spain (Soto 3 and Los Barrios). • the limited production from the Pecém power plant in Brazil and the sale of 80% of this power plant concluded in December • with the announced plans for Aboño and Pecém, the weight of coal on total generation is expected to be immaterial in 2024 providing further visibility on the delivery of EDP’s commitment to become coal-free by 2025 • the net increase in renewable capacity (wind and solar), which now accounts for around 60% of the total installed capacity. As a result of these operating conditions, there was a significant decrease in both EDP’s primary energy consumption (-51% YoY) and the CO2e emissions associated with electricity generation (-55%YoY). EDP reports its GHG emissions in accordance with the GHG Protocol Corporate Accounting and Reporting Standard (categories detailed in GRI Indicators | Environmental indicators). In summary: • Scope 1 emissions: includes stationary emissions from thermoelectric power plants, which represent 99.4% of the total, as well as emissions from the vehicle fleet, fugitive emissions (SF6) and those corresponding to natural gas consumption in buildings. In 2023, the scope 1 emissions totalled 4.3 MtCO2e, 55% less than in 2022. • Scope 2 emissions: refer to electricity consumption, including losses in transmission and distribution networks (the part produced by third parties), internal consumptions in power plants and consumption in administrative buildings supplied by third parties. In 2023, they totalled around 0.29 MtCO2e, 39% less than in 2022, considering only the technical losses, and also due to the significant reduction in emission factors in Portugal, Spain and Brazil, affecting the contribution of emissions-related losses in the distribution networks, which represents 91% of the total scope 2 emissions. • Scope 3 emissions: comprise all remaining indirect emissions upstream and downstream of the value chain, not accounted for in scopes 1 and 2. They essentially include emissions associated with purchased goods and services, capital goods, fuel and energy related activities and the sale of gas to end customers. The total value of 1\. Continued reduction of production from coal-fired power plants (coal- free by 2025) and natural gas (by 2030). 2\. All green by 2030: increase in renewable power, with the public objective of reaching 100% in 2030 4\. Promoting innovation aimed at mitigating the effect of climate change, contributing to the energy transition to a low carbon economy. 3\. Strengthening electrification and promoting energy efficiency, favouring the supply and demand of renewable energies and sustainable mobility solutions. 

079 Part I Integrated Annual Report 2023 Performance | Sustainability scope 3 emissions reached 8.1 MtCO2e, 13% less than in 2022, essentially due to the reduction in the categories of sale of gas to end customers, capital goods and fuel and energy related activities. Scope 1, 2 and 3 emissions (ktCO2e) The 54% reduction in Scope 1 and 2 emissions, despite the decrease in electricity produced (-8%), has led to a decrease in Scope 1 and 2 emissions intensity by around 50% compared to 2022, which is now 81 gCO2e/kWh. The production of electricity from renewable sources, by replacing fossil-based thermoelectric production in the country where they operate, avoids the emission of greenhouse gases in an amount corresponding to that which would be emitted by a mix of the existing thermoelectric portfolio in that country, producing the same electricity. In 2023, the avoided emissions amounted to 25.8 Mt CO2e, 14% more than in 2022, with the following distribution: wind - 72%; hydro - 20%; solar - 8%. The decarbonisation strategy also has an impact on improving energy efficiency along the value chain, contributing, on one hand, to the reduction of upstream primary energy consumption and, on the other hand, to greater efficiency in the end use of energy (third pillar of the mitigation strategy), avoiding GHG emissions. In the car fleet, the percentage of electric light vehicles reached 29% this year. It should be noted that EDP has assumed a commitment to electrify more than 40% of the light vehicle fleet in 2025 and 100% in 2030. Scope 1 and 2 specific emissions (gCO2/kWh) The fourth pillar regarding innovation is developed in chapter 3.4.13.2. Supply chain impact on Scope 3 emissions and data quality EDP’s ambitious renewable deployment plan brings challenges on supply chain related emissions. While in 2022 supply chain emissions accounted for 30% of Scope 3 emissions, by 2030, it is expected that over 65% of EDP’s non-commodity supply chain emissions are associated with solar and wind farms activity (construction, operation, and maintenance). Since 2022, one of the steps EDP is implementing to tackle the challenge of reducing supply chain emissions whilst growing its renewable deployment is the engagement with wind and solar suppliers with the purpose of improving data quality. The first major developments were on wind projects, where all Capital Goods emissions were calculated using the global warming potential available on the Life Cycle Assessment (LCA) or Environmental Product Declaration (EPD) of the specific turbine suppliers and models used in the 2022 projects. During 2023 EDP has applied the same methodology to solar projects, engaging with the main solar suppliers of modules, inverters and trackers to request environmental information from their equipment. For this reason, this was the focus of the efforts that took place in 2023, with the majority of solar suppliers already able to provide information on the carbon footprint of PV modules and inverters. 21,550 18,931 23,159 18,429 14,363 9,304 9,819 9,405 4,276 982 547 802 602 846 594 791 469 288 14,623 12,469 13,039 11,334 11,730 9,595 10,304 9,279 8,063 2015 2016 2017 2018 2019 2020 2021 2022 2023 Scope 1 Scope 2 Scope 3 628 361 280 344 266 230 157 176 160 81 46 8 2005 2015 2016 2017 2018 2019 2020 2021 2022 2023 2025 2030 

080 Part I Integrated Annual Report 2023 Performance | Sustainability As a result, EDP has been able to report with a higher level of precision on supply chain emissions, as seen in the graphs bellow, whilst mapping the carbon footprint impacts of both suppliers and their products. Evolution of supply chain Scope 3 emissions data quality Adaptation Ensuring the resilience of its electricity generation and distribution infrastructures is one of the priorities of EDP's climate action. To this regard, the group maintains the objective of having implemented in its business units, by 2025, climate change adaptation plans that ensure the resilience of infrastructures that may be exposed to extreme events of increasing intensity and frequency, given the reality we know today. To this end, the common corporate methodology supports the Business Unit plans already in place and the evaluation and quantification of physical risks are consolidated at corporate level in accordance with EDP's risk taxonomy, aligned with the TCFD recommendations. The level of exposure of EDP's infrastructures to physical climate risks is assessed considering the relevant climate variables, the short, medium and long-term IPPC scenarios and level of regionalisation. In addition to supporting the sensitivity analyses of the group's business units in the implementation of climate change adaptation plans, the physical risk analysis serves to support the decision for new investments.

081 Part I Integrated Annual Report 2023 Performance | Sustainability The transformation of Aboño’s thermal power plant into the Asturian green hydrogen valley, recognized as the continent’s most honored green hydrogen initiative by the European Commission. Differentiator factor: EDP's strategic commitment to be coal-free by 2025 and its investment in the transformation of Aboño’s thermal power plant into the Asturian green hydrogen valley set it apart from other energy companies. Aboño and Soto de Ribera’s unique location as a fair transition area sets them apart. Both initiatives follow circular economy principles due to the repurposing of two thermal power plants’ facilities, demonstrating EDP's commitment to sustainable and responsible practices in the energy transition. What lies ahead: EDP remains focused on achieving its decarbonization targets while ensuring a just transition for the community and its employees. The company's intention to close its last remaining coal plant, Los Barrios, in Spain, aligns with its ambitious decarbonization objectives, marking a significant step towards a cleaner and more sustainable energy future. Link for more information. Coal free by 2025 Decarbonizing for a fair transition, always committed to a sustainable future. Our approach: EDP is steadfast in its commitment to achieving a coal-free status by 2025 and transitioning to 100% renewable energy by 2030. The company has made significant strides in this direction, including the recent announcement of the disposal of the Pecém coal power plant in Brazil, with potential for conversion while retaining hydrogen capabilities. Moreover, EDP is actively pursuing the conversion of the Aboño II thermal plant from coal to a gas-fired facility, while simultaneously developing it into a Green Hydrogen hub, for which it has already been awarded the Important Project of Common European Interest (IPCEI) status. Additionally, EDP has sought authorization to close its last remaining coal plants, Soto 3 and Los Barrios in Spain, as part of its unwavering commitment to decarbonization. Furthermore, the company is decommissioning Puente Nuevo, Los Barrios, and Soto, with plans for several repurposing projects, including renewables, to ensure a smooth transition.

082 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.1.2. Decarbonising the world Alignment with the SDGs Objectives KPIs 2023 Target 2025 Installed capacity from renewable sources 86% 90% Smart meters installed in Iberia 91% 100% EV charging stations 8.5k >40K The fight against climate change and, in particular, the fulfilment of the climate goals of the Paris Agreement, reinforced in the Glasgow Pact, requires a five-fold acceleration in the pace of decarbonisation of the world economy. The electricity sector, through the use of renewable energies, is key to this acceleration by promoting the electrification of the remaining sectors, particularly transport, air conditioning in buildings and industry. EDP, by the nature of its activity, plays a pivotal role in this collective effort to combat climate change, an integral part of its global strategy. Leading the energy transition, contributing to a low carbon economy, has been a primary objective of the group, which is now a globally recognised reference among its peers. EDP contributes to the decarbonisation of the world economy on two different fronts: • through the decarbonisation of generation, through expansion into renewable energies and the progressive closure of thermoelectric plants • through the electrification of consumption, offering new low carbon product and service solutions. These services include: • distributed generation: installation of solar photovoltaic systems on a self- consumption basis and adapted to customers and local characteristics, including energy communities • sustainable mobility: support, advice and availability of in-home and out-of-home charging solutions currently available in Portugal, Spain and Brazil • energy efficiency: more efficient equipment and lighting, such as LED lamps, high- efficiency motors, electronic variable speed drives and heat pumps, as well as advisory services and energy audits. Renewable energies KPI 2023 Renewable energies TARGET 2025 86% installed capacity from renewable sources >90% 87% production from renewable sources 83% 2,3 GW installed capacity in centralized solar systems 5.5 GW 1,1 GW installed capacity in decentralized solar photovoltaic systems 3.7 GW 

083 Part I Integrated Annual Report 2023 Performance | Sustainability The path to decarbonisation involves a strong commitment to electricity production from renewable sources. The 2023-2026 Business Plan, presented to the markets in May 2023, emphasised the acceleration of the group's investment in energy transition, with a total planned investment of 25 billion euros, 85% of which in renewables, clients, and energy management. This unprecedented investment in renewable energy includes wind, solar and green hydrogen complemented by energy storage technologies. This unprecedented investment in renewable energy includes wind, solar and green hydrogen complemented by energy storage technologies. The Plan targets 18 GW gross added renewable capacity by 2026. On average, new gross installed capacity is estimated at 4.5 GW/year, during the period 2023 to 2026, preferably in low-risk markets with regulatory stability, favouring long-term PPA (Power Purchase Agreement) and energy purchases Contracts for Difference (CfD). In technological terms, 40% of the total planned investment will be allocated to solar technology (9.4 GW), 40% to wind onshore (5.0 GW), 12% to solar DG (2.1 GW), 5% (0.7 GW) to wind offshore, to be carried out by the company Ocean Winds (50/50 joint venture with Engie) and 3% to H2 and storage. To increase flexibility, EDP also intends to expand its energy storage capacity beyond its traditional storage in hydroelectric plants with pumped-storage reservoir. An increase of 0.5 GW of capacity is therefore planned for 2023-2026. The group's asset rotation strategy that crystallises value and funds additional growth opportunities, significantly contributes to this implementation. For the period 2023-2026, In 2023, EDP added 958 MW of wind farms, 1,715 MW of solar projects, 15 MW on storage. EDP also sold a total of 658 MW and 22 MW in decommissioning, resulting in a net addition of 2,008 MW of installed renewable capacity. In line with the marked investment planned in renewable energies, EDP has set ambitious targets, aiming at being all green by 2030, i.e., all power generated will be from renewable sources. By 2025, both the renewable installed capacity and generation should already exceed 90%, both indicators reaching 100% in 2030. At the end of 2023, the percentage of renewable installed capacity was 86%, i.e., up 7 p.p. compared with 2022. In 2023, electricity production from renewable sources accounted for 87% of the total electricity generated, 13% more than in 2022. Of this 87%, wind contributed with 56%, hydro with 25% and solar with 6%. The increase in this indicator was essentially due to: • the high increase in hydropower generation in the Iberian Peninsula (IPH close to the average year), after a 2022 of extreme drought, which also led to a lower use operation of the CCGT plants • the sharp reduction in production from coal-fired power plants in Spain and from the Pecém power plant in Brazil.

084 Part I Integrated Annual Report 2023 Performance | Sustainability Renewable energy generation (%) The decarbonisation route that the group has followed also involves the development of innovative projects, in anticipation of future business solutions. There is notable investment in areas such as energy hybridisation, which leverages potential synergies between different technologies (solar, wind, hydro and storage), the medium-term production of green hydrogen and solar and wind installations on offshore structures. EDP, through Ocean Winds, has been raising its profile in offshore wind growth with 1.5 GW gross capacity in operation by 2023, 1.9 GW under construction and a portfolio of 13.2 GW under development. 20% 58% 66% 56% 67% 67% 74% 76% 74% 87% 83% 100% 2005 2015 2016 2017 2018 2019 2020 2021 2022 2023 2025 2030 

085 Part I Integrated Annual Report 2023 Performance | Sustainability Distributed generation Anticipating the new energy paradigm, EDP has been consolidating its presence in a future in which power production, consumption and distribution will be increasingly decentralised. In this sense, the group offers a variety of solutions aimed at the specific needs of the various customer segments, through a diverse and competitive set of products and services in the solar photovoltaic field, which avoid emissions in the final consumption of energy. Through its suppliers, EDP offers this service in Portugal, Spain, Brazil, Italy and Poland, both on a transactional basis, with a personalised installation service tailored to each customer, and on an as-a-service basis, in which the investment and operation of the system is ensured by EDP for a certain period of time contracted with the customer. EDP Renováveis is also heavily involved in this activity, especially in the USA, APAC (Singapore, China, Taiwan, Vietnam, and Thailand) and Europe (Germany, the Netherlands, France and the United Kingdom, Belgium and Luxembourg. In 2023, EDP installed a total of 410 MW of decentralized solar photovoltaic systems and the total installed capacity by the end of 2023 amounted to 1,100 MW, which produced 1,045 GWh and avoided 570 ktCO2e of emissions. Decentralised solar installed capacity (%) (1) North America installed capacity includes 1 MW of storage. Sustainable mobility EDP has made a pioneering commitment to promoting electric mobility over the next few years. The objectives outlined are in line with the conviction that the fight against climate change and the decarbonisation of the economy will involve a greater penetration of renewable energies and the electrification of consumption, particularly in the transport, heating and cooling sectors. In conjunction with the group's strategic objectives of achieving 100% renewable installed capacity by 2030 and reducing its specific CO2 emissions by 95% in 2030 compared to 2020 levels, we are actively contributing to accelerating the transition to sustainable mobility. EDP is committed to achieving a 100% electric fleet (light vehicles) by 2030, which will require a strong investment in the renewal of its vehicle fleet. This transition will now be accelerated and will enable a 70% reduction in CO2 emissions from the global fleet, which consists of around 4,000 service vehicles. EDP has also committed to installing 40,000 public and private charging points by 2025 in the different geographies where it has commercial activity (Portugal, Spain and Brazil), as well as reaching 180,000 customers with electric mobility solutions by 2025. Within the scope of the services offered by EDP, which contribute to the decarbonisation of energy consumption, electric mobility also plays a key role. Given the potential for action, the company has internalised a large part of its efforts in the area of electric mobility, through solutions (products, services and charging networks), mostly aimed at its customers, but also in internal measures at group level. In this regard, in 2023 EDP maintained the "Sustainable Mobility Support Credits" initiative, which allocates an annual sum to employees to use in shared mobility modes (excluding individual combustion-powered vehicles). KPI 2023 Sustainable mobility Target 2025 107 k customers with electric mobility solutions 180k 29,4% electrification of the light fleet 100% (in 2030) 8,510 charging points installed >40k 15.3% 2.0% 9.4% 3.6% 22.2% 47.5% Portugal Spain South America Rest of the Europe North America (1) APAC 

086 Part I Integrated Annual Report 2023 Performance | Sustainability In addition, EDP's approach has included the promotion of an ecosystem of partnerships and initiatives for electric mobility at international level: • EDP actively participates in Eurelectric - where it shares the E-mobility working group since 2023 - which aims to promote the implementation of a regulatory framework favourable to the development of the electric mobility sector, as well as innovative business models that benefit both companies in the sector and end consumers, and thus support the transition to clean mobility. • EDP is a board member of ChargeUp Europe, an association of companies in the EV charging infrastructure industry, which actively works to defend public policies to promote the rapid and uncomplicated deployment of EV charging infrastructure in Europe. EDP was the first Portuguese company to join the association. In 2023, ChargeUp Europe published the second edition of the State of the Industry report, a publication that provides, in a simple and accessible way, a set of insights, facts and case studies on the EV charging sector. EDP actively contributed to the development of the report and also shared its own case study on the smart charging management of the more than 170 charging points installed at its headquarters in Lisbon. • EDP is part of The Climate group's ambitious EV100 initiative, through which it has made a commitment to transition its light fleet of more than 3,000 vehicles to electric vehicles by 2030. • EDP is a founding member of the Portuguese Association of Electric Mobility Operators and Suppliers (APOCME), an association that aims to promote the development of electric mobility, not only as a vector for decarbonising the transport sector, but also for integrating the electric vehicle as a resource for security and energy transition. • In order to increase awareness and visibility of electric mobility, EDP continues to promote the "Portugal Mobi Summit", the largest urban mobility event in Portugal for the sixth consecutive year, in partnership with the Global Media group. • In Spain, EDP is part of the Asociación Empresarial para el Desarrollo e Impulso de la Movilidad Eléctrica (AEDIVE), whose mission is to promote and contribute to the competitiveness of sectors related to the electric mobility value chain, in order to boost the development of the market, creating a solid and stable framework for it. • EDP Spain also participates in events that promote electric mobility, such as VEM - an exhibition of electric vehicles whose main aim is to bring electric mobility to private consumers and public and private companies (fleets) in Madrid – and the Global Mobility Call - a world congress whose aim is to promote collaboration between companies and generate public-private partnerships that contribute to the development of sustainable mobility. Products and Services The EDP group has a diverse commercial offer of products and services, particularly in Portugal, Spain and Brazil. Throughout 2023, EDP worked to provide the best charging solutions for its customers. The group has focused on the one hand, on developing ever more complete electric mobility solutions tailored to the needs of the growing market and, on the other hand, on having more competitive prices, thus reaching more and more electric vehicle drivers. In Portugal EDP, through its subsidiary EDP Comercial, supplies and installs charging solutions for electric vehicles through charging stations for the B2C and B2B segments, as well as being an active operator of charging points on the public network. EDP currently has partnerships with the five largest rental companies in Portugal (Leaseplan, Arval, Leasys, Locarent and Kinto), and already has more than 300 charging points contracted in this segment. EDP manages a constantly updated website with relevant information to help customers overcome the initial barriers of this new sustainable transport paradigm and with a simulator to help customers choose the best solution for their electric vehicle according to their mobility profile and home electrical installation. In 2023, EDP invested in the digital transformation and evolution of the technological ecosystem of electric mobility EDP Charge. The EDP Charge app allows customers to charge on the public network, at home and in the workplace. Using this new app, customers can check the availability of the most suitable chargers for their vehicle, start charging digitally, simulate charging session costs and consult their charging history, providing a simple and digital experience for customers. The new EDP Charging Portals, for condominium managers and B2B customers, allow various functionalities, including managing and carrying out remote actions on chargers, monitoring charging sessions, assigning drivers access to chargers, setting charging caps for employees, among other features that give customers autonomy and flexibility to manage their electric fleet. 

087 Part I Integrated Annual Report 2023 Performance | Sustainability Sales of the "smart charging" service were also boosted in 2023 - it is a differentiating service in the market that makes it possible to distribute the electrical power made available by the network in a balanced way among all the vehicles that need charging, avoiding costly investments in reinforcing the electrical infrastructure of buildings. With the exponential growth of mobility, this topic has been one of the main concerns of customers. In terms of charging solutions for the B2B segment, the offer available on Effizency Sales - an EDP Comercial platform that allows access to personalised energy efficiency recommendations and technical services adapted to the business - has been updated with charging solutions adapted to the real needs of business customers, both for proven access spaces and public access spaces, with different levels of personalisation and also available as-a-service. Also, for the business segment, a new product has been launched - the EDP Charge Fleet card. This card allows company employees to manage their charging anywhere (at home, in the workplace or on the public network). We believe that this is an innovative product that brings convenience to companies and their employees, offering a digital charging experience integrated into the private and corporate spheres. In Spain MOVE ON is a global tool for connecting with both customers, via the app, and partners, on the portals, which has been in operation throughout 2023 despite having a plan to switch to global systems. Thanks to the agreement reached with one of Spain's leading low-cost petrol companies - Petroprix - the installation of the first battery-powered ultra-fast charging network in Spanish territory has begun. This project was recognised by the MOVES SINGULARES programme for its innovative approach to limiting the impact of power availability at more than 40 sites through the use of storage systems. In order to make the user experience as easy as possible, EDP has continued to focus on being an operator open to interoperability and ad hoc payment. To this end, EDP's charging points are connected to the main European and Spanish interoperability facilitators, such as Electromaps, Hubject and DCS, and it has also signed direct bilateral agreements with other charging point operators, such as Zunder, Wenea and Repsol. In addition, and also with the aim of facilitating the user experience, thanks to the alliance with Mastercard and Banco Santander through GETNET and Worldline, the installation of charging points where it is possible to pay by bank card has begun. In the corporate segment, EDP manages charging infrastructures in company buildings for the drivers of the corporate fleet, and this includes the management of energy payments. Public charging network In Portugal Estimated electric charging needs for the coming years point to a demand for 20,000 charging points by 2025. EDP continues to make a positive contribution to the creation of a vast public charging network, increasing the number of charging points in Portugal, not only through strategic partnerships in publicly accessible commercial locations (Brisa, McDonalds, Burger King, etc.), but also by investing in partnerships with small and medium- sized companies, contributing to greater capillarity of the public charging network. In 2023, EDP grew by +14% in contracted charging points and closed several important partnerships that resulted in more than 2,350 contracted charging points. EDP's growing network of partners, who provide space on their premises for the deployment of charging points, continues to be crucial for EV users, ensuring greater capillarity of the public charging infrastructure. It is important to note that 2023 was the year with the highest utilisation of the public charging network operated by EDP with more than 500,000 charging sessions in Portugal. EDP leads the CEME market - the market for energy sold in public charging - with more than 83,200 cards issued, allowing its users to benefit from one of the most attractive tariffs in the public charging market. In Spain By the end of 2023, EDP had contracted a total of 2,444 public charging points. Agreements have been reached with organisations such as town halls (Ayuntamiento de El Franco), hotels (Hotel El Albir) and supermarket chains - such as Carrefour, a partnership in which 978 charging points have been contracted. 

088 Part I Integrated Annual Report 2023 Performance | Sustainability In Brazil EDP has opened two new public charging stations, with two chargers each, one ultra-fast (>150 kW) and the other semi-fast (2x22 kW). One of the charging stations was installed in the state of Minas Gerais, an important point for the construction of the electric corridor on one of Brazil's main motorways. EDP ended the year with 12 ultra-fast charging stations, out of the 18 planned in the project. The E-Lounge Powered by EDP was also inaugurated, a public space with a 60 kW fast charger and four 22 kW chargers, aimed mainly at app drivers. In the state of Espírito Santo, EDP completed the first electric bus project in partnership with a local operator for private transport of company employees between the capital and three neighbouring municipalities, covering a radius of more than 100 km. All the projects are part of ANEEL's Research & Development programme. Energy efficiency KPI 2023 Energy efficiency Target 2025 46% B2C customers with sustainable services 25% 13 MtCO2 emissions avoided by customer 15 MtCO2 EDP promotes the improvement of energy efficiency throughout the value chain as an important contribution to decarbonisation, contributing to greater efficiency in the end use of energy by offering its customers low carbon products and services. In 2023, 46% of B2C customers on the liberalised market had sustainable services, such as energy efficiency, electric mobility or decentralised solar solutions. The target set for 2025 (25%) has already been reached and is fast approaching the goal of 50% of B2B customers with sustainable services by 2030. In Portugal, the “Casa Elétrica” programme continued, focusing on B2C customers, aiming to promote the switching from butane or propane gas consumption to electricity, with an impact on energy consumption and safety, and in alignment with the strategy of electrification of consumption. In 2023, EDP launched two new solar photovoltaic offers: • Solar Water Heater: a solution that combines solar panels with a water heater, taking advantage of surplus solar production to heat water. The water heater not only optimises the operation of the solar system, but also includes a management system that allows you to have only the amount of hot water you need when you need it and in the most economical way possible. • Solar Apartments: a solution that allows customers living in flats to take advantage of solar energy to reduce their energy bills and their energy dependency. In the corporate segment, EDP supports companies in the implementation of integrated energy efficiency services by offering solar energy, sustainable mobility, and consumption management solutions. For B2B customers in Europe, in 2023, EDP boosted the contracting of approximately 500MW of solar photovoltaic solutions for self-consumption, for installation in companies from various sectors of activity, ranging in size from large customers to small businesses. In order to support the decarbonisation efforts of the business fabric in the Iberian Peninsula, EDP offers a multi-sector, turnkey Going Net Zero solution to support the transition to emission-neutral businesses. This service includes the measurement of corporate greenhouse gas emissions or product catalogue through life cycle analysis and promotes the implementation of mitigation plans. Also in 2023, EDP continued to focus on diversifying its offer, through solutions that promote the energy transition of companies, through innovative and inclusive solutions with special emphasis on local energy community solutions, that exceeded all business forecasts for 2023 with more than 80 MWp contracted. In Brazil, EDP also invests in energy efficiency initiatives, either through distribution companies, which operate in the regulated market, or through the service company EDP Smart, which operates in the liberalised market. The distributors, according to the legislation of the Brazilian electricity sector, have the obligation to apply 0.4% of net operating revenue annually in Energy Efficiency Programs (PEE) and 0.1% in the National Program of Electric Energy Conservation (PROCEL). EDP Smart offers solutions to improve energy efficiency (lighting, air conditioning) and also in the area of electric mobility and distributed generation. By 2023, the implemented measures led to energy savings of 33.3 GWh and 30 ktCO2 avoided. 

089 Part I Integrated Annual Report 2023 Performance | Sustainability Energy efficiency services generated around 571 million euros of income in 2023, representing an 16% increase compared to 2022. The set of energy efficiency, sustainable mobility and distributed generation initiatives carried out in 2023 led to an estimated energy saving of 496 GWh, avoiding the emission of 1,066 ktCO2, including those corresponding to the sale of electricity from renewable sources, through the guarantees of origin scheme. Since 2015, the savings generated from sustainable services have made it possible to avoid the emission of 13 MtCO2, which represents around 86% of the 2025 target. 

090 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.2. Pollution Ensuring pollution prevention is a key strategic focus for the EDP group and represents a core commitment within its Environmental policy to "effectively manage environmental risks, with a specific emphasis on preventing pollution and responding to emergencies in the event of accidents and/or disasters." The environmental aspects and potential impacts are assessed within the scope of the environmental management systems in facilities and activities, certified according to ISO 14001 across the EDP group, also in the thermal and hydroelectric production facilities in Portugal to comply with the Eco-Management and Audit Scheme (EMAS) registration. In pollution prevention, we employ the best available techniques to eliminate potential adverse effects, address impacts when no compatible and viable alternative exists, and consistently monitor and control existing impacts. Our pollution prevention measures are aligned with the following hierarchy towards achieving zero pollution in the air, water, and soil: Source: European Environment Agency – Zero pollution action plan The production and distribution of electricity have the most significant direct environmental impact. Key environmental aspects that have a negative impact include fuel and chemical consumption, greenhouse gas and atmospheric pollutant emissions, water usage, treated effluent discharge, effects on wildlife and plant life, and noise in specific facility scenarios. Thermoelectric power plants have equipment to reduce polluting atmospheric emissions, liquid effluent treatment and are subject to environmental permits that set emission limits. The monitoring results are made available to the competent authorities. The reduction of pollutant emissions in 2023 is in line with the objective of not producing electricity from coal after 2025. In the electricity distribution activity, the main impact mitigation measures focus on the integration of overhead lines into the landscape, installation of sound barriers, and oil retention systems. In the management of transformers contaminated with polychlorinated biphenyls (PCBs) with a concentration of more than 50 ppm, in addition to complying with the legislation in force, EDP adopts the best practices for identifying, screening and forwarding PCB waste for appropriate final treatment. Equipment with concentrations higher than 50 ppm, which are increasingly residual in the group, will be completely deactivated by 2025. The implementation of the circular economy strategy (please see 3.4.5 Circular economy), particularly at a time when several dismantling projects are underway, also supports the reduction of hazardous waste towards achieving zero pollution to the soil. In order to respond to emergencies, internal emergency plans and, when applicable, external emergency plans are defined, with scenarios of potential emergencies or serious accidents involving hazardous substances. This response capability is trained through simulation exercises, and lessons learned are incorporated to improve response capacity. In 2023, there were 253 environmental simulation exercises, and no environmental accidents occurred, although there were 211 small oil spills, totalling 37 m 3 of oil spilled. These spills are mainly due to theft in transformers in electricity distribution activity. These repair situations are carefully managed by specialist teams, and the contaminated land is properly disposed of at an appropriate final destination. As a pollution prevention measure for these minor spills, the mineral oil in the transformers has been replaced with vegetable oil, thus eliminating the hazardous nature of the waste produced. 

091 Part I Integrated Annual Report 2023 Performance | Sustainability In the activities of the EDP group, the following actions stand out in the context of pollution prevention and nature protection: • contractual environmental requirements for contractors, with penalties applied if these requirements are not met • environmental audits and inspections at different stages of the facilities' life cycle (construction, operation, maintenance, and dismantling) in various activities with environmental impact • analysis of causes of occurrences with environmental impact and identification of rapid corrective and preventive measures • implementation of noise minimization measures • environmental training for employees involved in activities that impact the environment. The number of environmental complaints has decreased again in all areas of activity and has reduced globally 40% (vs. 2022). The theme biodiversity represents 41% of the reasons for environmental complaints, followed by the theme noise, with 29% representation. On the other hand, in order to have a positive effect on the environment, EDP continues to invest heavily in improving technologies and in initiatives to prevent and mitigate the environmental impacts of its operations, totalling 522 million euros in 2023. 

092 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.3. Water and marine resources 3.4.3.1. Water management EDP recognises access to drinking water and sanitation as a universal Human Right and assumes its responsibility in the pursuit of SDGs, in particular SDG 15, contributing to the sustainable use of freshwater ecosystem services, and SDG 7, seeking to ensure the supply of clean and affordable energy for all. Under its Environmental Policy, EDP is committed to mitigating its impacts, managing risks and promoting the ongoing improvement of processes, practices and performance through a collaborative approach with stakeholders for the sustainable management and efficient use of water. Water is a vital resource for electricity generation, particularly hydroelectric power, which is an important part of EDP's renewable generation portfolio and is crucial to its strategy of reducing CO2 emissions and mitigating climate change. Although, and contrary to the other activities of the organization, the use of water in hydroelectric production is not considered consumption, EDP monitors the volume of water managed in these assets, which has reached 131 million cubic meters, +17% compared to 2022, as a result of favourable water conditions in the Iberian Peninsula, after a year of extreme drought (2022), leading to increased hydroelectric production and reduced operation of CCGT power plants. This indicator heavily depends on the hydroelectric productivity index in Portugal, in which the water portfolio is more relevant, standing at 0.99 (compared to 0.63 in 2022), 1 p.p. below the average hydrological year. The following table highlights the impact on water consumption and operational depend- ence on the resource in EDP group's assets, namely in thermal power plants, hydroelectric plants, solar parks, and wind farms: ASSET TYPE WATER CONSUMPTION DEPENDENCE Thermoelectric power plants High High Hydroelectric power plants Low High Solar farms Low Low Wind farms Low Low Water consumption (%, Thousand m 3 ) Water withdrawal (%, Thousand m 3 ) 25% 1,339 6% 324 69% 3,767 75% 4,091 Brackish Fresh Water stress Non water stress Fresh 1.0% 5,659 Brackish 0.9% 4,588 Salt 98% 533,056 

093 Part I Integrated Annual Report 2023 Performance | Sustainability The specific consumption of fresh water changed in 2023 (-50% compared to 2022), with the decrease in the EDP group's coal-fired electricity generation (-52% vs. 2022), which is justified by the limited production from the Pecém power plant in Brazil, with the sale of 80% of this power plant being completed in December, and by the significant reduction in production at coal power plants in Spain. EDP monitors potential shortages, water quality and sediments, as well as the impact of the management of this resource on biodiversity, for which it undertakes mitigation activities such as the release of ecological flows, the transfer and transport of fish, and support for scientific research on these topics. To assess exposure to water stress, EDP uses the World Resources Institute's Aqueduct tool to carry out an initial high-level risk assessment, mapping its generation assets against a widely recognized indicator of water availability (Baseline Water Stress). The assessment of exposure to water risk is carried out on a river basin scale, and then a local analysis is conducted taking into account quantitative information from national institutions and the experience of the operational in-house teams. This analysis is carried out for all geographies where EDP has generation activities, whose water abstraction sources are located close to the facilities (Portugal, Spain and Brazil). Wind generation and distribution assets are excluded, given their low dependence on water. According to this analysis, it should be noted that the Pecém thermoelectric plant in Brazil is located in a water stress zone. Since 2010, EDP has responded to the CDP Water Security, where it provides a detailed description of its ongoing initiatives. In 2023, EDP achieved the highest performance level of this index (leadership) with a rating of A-. In 2023, EDP reached the level of higher performance (leadership) with the rating A- CDP Water Security 

094 Part I Integrated Annual Report 2023 Performance | Sustainability 68 hydroelectric power stations totaling around 7,000 MW. Differentiator factor: One of the main features of Frades II (Venda Nova III) is the variable speed technology that allows for power variation when operating in pump mode, as well as the exceptional ability to provide grid stability services. Overall, dams and pumping technology are real facilitators of the energy transition and one of EDP's main focuses on becoming a totally green energy company by 2030, by promoting more efficient management of the electricity grid in periods of higher demand or intermittency of other non-dispatchable sources - such as solar and wind. What lies ahead: EDP is exploring opportunities at Iberian level to boost the use of existing pumping technology (optimisation of the turbine-pump at the Torrão power station) and to carry out conversions, such as the one at the Alto Lindoso power station, in order to increase the overall efficiency of the system and thus contribute to the energy transition. The role of hydropower in the Energy Transition Hydropower and pumped storage as key drivers for the energy transition. Our approach: EDP Geração owns 68 hydroelectric plants totaling around 7,000 MW in Portugal, Spain and Brazil, including 10 pumped storage plants in Iberia. In addition, there are two technologies developed in the context of storage: hydro pumping, with greater scale and technological maturity; and battery storage, as part of hybridisation projects. One of the best examples is Frades II (Venda Nova III), equipped with the most powerful variable-speed reversible units on the Iberian Peninsula. Countries: Portugal, Spain and Brazil 

095 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.4. Biodiversity and ecosystems Biodiversity faces a critical threat, emphasizing the urgent need to rehabilitate damaged ecosystems. There are high hopes for reinforcing the global commitments and targets outlined in the Kunming-Montreal Global Biodiversity Framework, which was adopted in late 2022. This Framework aims to achieve a world living in harmony with nature by 2050, with key targets including the restoration of 30% of all degraded ecosystems and the conservation of 30% of land, water, and seas by 2030. According to the United Nations Environment Programme (UNEP), the degradation of marine and terrestrial ecosystems has a significant impact on the well-being of 3.3 billion people worldwide, with an associated annual cost of approximately 10% of the planet's gross product due to the loss of species and essential ecosystem services. 3.4.4.1. Policy and targets DP's new Business Plan for 2023-2026 includes targets related to Nature, including a corporate objective to attain a Biodiversity Net Gain in all new projects with significant residual impacts by 2030. By 2026, EDP aims to have implemented Net Gain Biodiversity tracking systems supporting 100% of new projects, signifying the need for all internal knowledge and resources to be in place to enable the company to meet Nature's 2030 targets. Under this 2026 target, EDP maintains its commitment to have 100% of action plans in place whenever its facilities are recognized as having high biodiversity risks. Under this level of ambition EDP will work towards a no net deforestation practice. Additionally, EDP maintains its commitment to not build new generation facilities in Natural Heritage Sites, from UNESCO’s World Heritage list. EDP’s Environmental Policy, includes specific commitment to the protection of biodiversity: • contributing to the reduction of biodiversity loss, prioritising mitigation line management and aiming for a positive outcome on the biodiversity balance sheet in the long term • contributing to the deepening of scientific knowledge of biodiversity and ecosystem services, including through the establishment of partnerships. This Policy is supplemented by internal guidance to establish a shared understanding of how to act at project level, emphasizing the use of the mitigation hierarchy approach throughout the project life cycle, as the initial step in fulfilling the overall biodiversity commitments. EDP’s Biodiversity Strategy, based on SBTN; TNFD; Business4Nature; CSRD. 3.4.4.2. Key developments and performance in 2023 In 2023, EDP’s started using IBAT to characterize our generation and transport assets and as an early risk screening tool for new projects; The use of this tool reinforces the mitigation hierarchy approach, integrating biodiversity into the investment decision-making process. Following IBAT datasets, by the end of 2023, EDP reviewed its data, disclosed in GRI indicators | Environmental indicators. During 2024, EDP will drilldown this info to improve data quality, supported by internal Geographic Information Systems. During 2023, EDP’s Biodiversity strategy was reinforced, to better support alignment with international core standards, such as Taskforce on Nature-related Financial Disclosures (TNFD), Science Based Targets Network (SBTN) and the new European CSRD, in accordance to figure above. In short: • several programs at Business Unit level were designed and several others reinforced (table in page 96) 

096 Part I Integrated Annual Report 2023 Performance | Sustainability • biodiversity indicators were reviewed to improve monitoring of related risks decision making process. • internal workshops for the sustainability teams in EDP’s Business Unit were promoted to align local action with the Nature Based Solutions’ concepts and practices. During 2024, EDP will strengthen TNFD content to improve alignment and will reinforce action at operational level, mainly working in early risk screening processes. In addition, during 2023, EDP continued to strengthen its public commitments in this area by: • updating its commitments made under Act4Nature-Portugal. Act4Nature is an initiative led by the BCSD-Portugal and fostered by the biodiversity working group since 2020, where EDP is part of the Steering Committee and the Advisory Board • in Brazil, the Brazilian Business Council for Sustainable Development CEBDS, launched in October 2019 the Brazilian Business Commitment to Biodiversity aiming to emphasise the importance of Biodiversity and ecosystem services for businesses. This initiative is framed by nine global goals and targets have actions in progress that are subject to re- evaluation/definition depending on the evolution of approaches, indicators and metrics that are being defined internationally • in 2023, EDP made a similar commitment in Spain under the Iniciativa Española Empresa Y Biodiversidad (IEEB), promoted by Fundación Biodiversidad. By endorsing the Pacto por la Biodiversidad y el Capital Natural, EDP pledged to adhere to 10 common principles crucial to the Kunming-Montreal agreement. The company also committed to assessing and sharing its impacts and dependencies on biodiversity and natural capital, and to develop a roadmap for mitigation. During 2023, EDP published its Biodiversity Report 2020-2022, detailing its initiatives on going and additional indicators and practices can be consulted in it. 

097 Part I Integrated Annual Report 2023 Performance | Sustainability Biodiversity projects ongoing worldwide (non-exhaustive) Generation Portugal EDP Generation in Portugal launched the Nature4Tomorrow Program, aiming to promoting biodiversity and contribute to CO2 sequestration. The Alto Lindoso reforestation project, covering 22 hectares in the National Park of Peneda Geres, is the first project aiming to enhance ecological conditions and support EDP's commitment to Net Zero by 2030. The project benefits the environment but also promotes economic benefits for local communities and green job creation. It is aligned with the SBTN AR3T framework, focusing on the assessment of flora species, implementing measures for positive change, and embracing Nature-based Solutions. Engaging with local communities and authorities is paramount for the project's success, raising awareness about the pivotal role of biodiversity in socioeconomic development. Operationally, the project involves improving the ecosystem by densifying weakened cork oak trees with native forest species and controlling invasive alien species. The project's area has forest management certification and certification in ecosystem services. Spain In Spain, EDP is working on improving its understanding on the impacts of the environmental footprint of its generation assets on natural capital, with special emphasis on ecosystems and ecosystem services (ES). To this end, a methodology has been developed to measure the impact of its facilities on natural capital still in its early stages but making it possible to measure the impact of a facility at a local level, mainly using information from its environmental footprint. The tool integrates three variables for measuring the impact: (i) scope of the impacts of the facility, (ii) severity of these impacts and (iii) relevance of the ecosystems and ES impacted by the facility. As a pilot study, the tool has been applied at EDP's Aboño Thermal Power Plant, located on the coast of Gijón, Asturias (Spain), where the main impacts came out as (i) terrestrial acidification, (ii) urban land occupation and (iii) terrestrial ecotoxicity. Networks Portugal For networks in Portugal, two main priorities prevail in managing biodiversity protection: 1) For more than 20 years a multi stakeholder protocol, involving local authorities and NGO allowed a thorough mitigation program focusing reducing the risks of bird collision and electrocution. By the end of 2023, more than 1,300 km were adapted, with significant expected bird loss reduction. 2) Managing more than 68 thousand km of network extension, E-REDES is enhancing the resilience of its network to extreme events, particularly rural fires, through preventive measures and planned protection of infrastructure. Under its partnership with ForestWISE, the company is focusing on monitoring vegetation proximity, investing in advanced technologies, and working for effective biodiversity management, namely when inside some sensitive or classified natural area, looking to promote competitive use of the land. In 2023 the partnership behind the Birdlife Protocol was extended for another five years. Spain NATURNET is a tool designed to assess the effects of medium and high voltage overhead power grids on impacted habitats, the services they offer, and the most vulnerable species within these habitats. It enables the management of risks associated with power grid impacts and facilitates investment decisions to minimize these risks. The analysis covers all high and medium voltage overhead networks spanning the communities, with a detailed examination down to the municipality level. The assessment focuses on the impacts on habitats, species, and ecosystem services, utilizing official external sources of information cross-referenced with internal network data. This knowledge allows for the management of risks associated with constructing new lines at the municipal level and the exploration of alternatives with reduced impact. Furthermore, it provides opportunities to invest in suitable locations to compensate for damaged services and habitats. Renewables Europe In Iberia, it can be highlighted the different projects on-going to protect several species of birds, mostly associated with mitigation and compensation activities associated windfarms operations. One of the oldest partnerships is with GREFA, a Spanish environmental NGO, with whom EDP Renewables collaborates to reintroduce the Bonelli Eagle in Madrid and the central peninsular area, as well as in projects to improve lesser kestrel and Egyptian vulture populations in other regions of Spain. Additionally, projects to improve pollination within the area of management are being tested. An example is in Poland and in Hungary, where flower meadows are being planted to reinforce biodiversity, create asylum for rare and protected species especially insects and protect the land from drought. North America In North America, biodiversity protection is centred around applying the mitigation hierarchy. For projects where biodiversity impacts could not be avoided or minimized, North America conducted a wide range of compensation initiatives from conserving bat habitats to restoring wetlands and sensitive habitats, tailored to meet local needs and regulations. For instance, in Mexico, EDPR is working to preserve rare desert plants through flora relocation and restoration across approximately 330 hectares at two windfarms, and a partnership with a local university supports these activities. Meanwhile, in New York, an ongoing offsite wetland and stream restoration project aims to enhance the habitat of three federally endangered mussel species using nature-based remediation techniques to address streambank erosion and sedimentation. The restoration activities, covering 13 hectares, also seek to safeguard adjacent floodplain wetlands from potential washouts during high rainfall events. Moreover, in the USA, companies have the option to purchase credits from recognized biodiversity banks. EDP Renewables has utilized this opportunity to cover 545 hectares of land conservation in the Midwest, thereby increasing the availability of suitable maternity roost habitats for bat and its conservation purposes. LatAmerica In Brazil, EDP is reinforcing its IT geographic information systems by mapping all its assets against different layers of protected and sensitive areas, namely all IBAT datasets. This initiative will improve risk analysis and the decision-making process, not only for the current portfolio, but for future business expansion in Brazil. Locally, EDP in Brazil maintains several initiatives to protect biodiversity, within the surroundings of its facilities, from compensatory forest planting in several locations to seeding distribution and education programs. 

098 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.5. Circular Economy KPI 2023 Promoting the Circular Economy Target 2025 74% Accelerating circularity in renewables in terms of operational waste and decommissioning >80% -76% Reduction of operational waste -82% 42% Increased rate of recyclability in the operation 85% -88% Reduction of water consumption -78% While renewable energy sources and electrification are vital first steps in transitioning to zero-emission models, the significant growth of renewable energy technologies poses challenges in material supply, production, and end-of-life management. The growth of these technologies must be established as part of a circular economy approach to prevent new environmental problems and boost job creation and economic development. The increasing use of renewable energy sources will also lead to the decommissioning of EDP’s thermoelectric plants, which will require a circular economy strategy to address the large volume of land, assets, and materials involved. The Circular Economy is one of the axes of the EDP group's sustainability strategy, constituting an important pillar of its Environment Policy. For EDP, the Circular Economy is based on the efficient use of natural resources from a life-cycle analysis perspective, aiming to: • minimise the use of natural resources necessary for the proper execution of its activities • efficiently optimise and manage internal products and services capable of leveraging the circular economy in its customers • maximise the recovery of waste and its reintroduction into the economy as by-product. EDP´s Circular Economy strategy is based on three fundamental pillars: Reduction, Optimisation and Valorisation as a way to promote the increase of circularity in the business, implemented through seven priority axes of action (see figure in the next page). Close the loop program “As an innovative solar recycling company with industry-leading technology that can recycle and recover over 95% of the valuable material from a solar panel, we are thrilled that EDP Renewables North America has chosen SOLARCYCLE as a top, trusted partner for its new Close the Loop Program. With this new partnership, EDP is not only demonstrating its leadership on sustainability, but also joining us in our mission to build a more circular industry that strengthens the solar supply chain.” Suvi Sharma, CEO and Co-Founder of SOLARCYCLE

100 Part I Integrated Annual Report 2023 Performance | Sustainability The EDP group is committed to providing innovative and competitive solutions by ensuring coherence across all its activities and ecosystems: • in power generation, the group aims to reappraise renewable energy supply chains throughout their value chain and manage thermoelectric assets until their decommissioning • in infrastructure and network, the group aims to redefine the value chain of major assets through "Circularity by Design" and use digitalization to accelerate the role of the network as a platform • in end customers, the group aims to facilitate their transition to circularity through new products and services • in suppliers to support and leverage the entire supply chain towards circularity. All other areas, from digital infrastructures to trading to office management, are also actively involved. Achieving high levels of circularity is only possible through a collaborative and systemic approach. Therefore, EDP is collaborating with international organizations and platforms, as well as in its main countries of operation, including European countries, the United States, and Brazil. The group collaborates with institutions, companies, NGOs, universities, and other stakeholders to increase knowledge and understanding of the circular economy and support the system transition. EDP has set out four ambitious circular economy targets for 2025, contributing to its commitment to SDGs 8 and 12, promoting decent work and economic growth, and sustainable production and consumption. To achieve these objectives, a corporate roadmap was determined, to which projects and initiatives developed by the different Business Units of the group contribute. In 2023, there are several best practices for circular economy, for each of the priority axes of action, which are detailed in the following table. The 7 EDP’s axes of action for circular economy

Eight critical assets were selected for assessing their circularity, including interviews with suppliers. In the future, the analysis will be extended to more assets with a new circularity assessment tool. The integration of this analysis into the procurement process and green purchasing criteria is a significant step in reducing E-REDES' environmental impact on the supply chain. E-REDES - Portugal CIRCUMETRIC 2.0 Circumetric is a corporate tool designed to assess the circularity of initiatives, with the primary goal of raising awareness and identifying improvement measures. In 2023, significant enhancements were made to the tool, and its scope was expanded to cover all geographies. This expansion ensures the tool's continued functionality while incorporating new features to better serve its purpose. EDP Spain – Global Energy storage system with batteries at solar farms Installation of batteries for energy storage in solar farms with the aim of improving the flexibility of electrical systems, thus incorporating greater renewable capacity. EDP Renováveis - Europe and Brazil Promotion of rationalization of water consumption Minimizing water usage in hydroelectric plant landscapes is a key priority for us. To achieve this, we are actively incorporating rainwater reuse practices for irrigation. Additionally, we are conducting a comprehensive assessment to identify opportunities for streamlining water consumption. To address areas with less developed water management, such as hydroelectric power plants, we are executing an action plan. This plan focuses on enhancing consumption accounting measures and initiating pilot projects in gardens. These projects involve selecting climate-appropriate vegetation and optimizing watering practices for increased efficiency.

Tests in a laboratory with crushed porcelain in concrete blocks showed positive results. As a result, the solution was to reuse this material on a larger scale, using it as fine aggregate in civil construction. This approach ensures 100% utilization of the previously considered waste material. EDP Brazil - Brazil Wind turbines end-of-life Promote the search for innovative solutions for wind turbine blades and PV panels at the end of their life. Integrated in EDP Lite Up project, blades out of use were donated. Also a framework was developed to establish the strategies for resource valorization at the end-of-life of wind or solar projects in EDPR - “Guidelines for end-of-life projects at EDPR”. EDP Renewables – EU&LATAM Recycling solar panels EDP Renewables, in partnership with SOLARCYCLE, has launched a programme to recycle materials used in renewable energy projects in North America, addressing one of the main challenges of renewable energies. The aim is to promote a circular economy and reduce environmental impact by using resources more efficiently and extending the useful life of products. The goal is to recover 85 % of waste by 2026, helping to reduce pollution and preserve natural resources. EDP Renewables – NA Cattlemen II Circularity Plan EDP Renewables created a comprehensive circularity plan for offtaker Microsoft Corporation, which includes the proper recycling and disposal of all project components, equipment and material both during and at the end of the useful life of the project, Cattlemen II Solar Park in Milam County, Texas. Within the plan, EDPR NA highlights means, methods, scope, and strategy for how the company promotes asset recovery, recycling, and the efficient use of resources through each stage of the project lifecycle, including development, construction, operation and maintenance, and decommissioning. EDP Renewables – NA New business models Solar energy sales as a service Development of a business model as a service for solar, in which the management of panels made by EDP contributes to their better maintenance and, therefore, to an extension of their useful life, in addition to the fact that when the customer no longer needs them, they can be reused by other customers. EDP Comercial and EDP Spain \- Iberia Circular supplies Integrating circularity in suppliers’ evaluation At Iberia, our global procurement team is actively implementing a series of measures to seamlessly incorporate circular economy principles into the assessment processes for our suppliers. Specifically, we are enhancing the supplier registration questionnaire to gather information about initiatives and practices related to the circular economy undertaken by our partners. Additionally, we are modifying the contractual performance evaluation questionnaire to encompass criteria pertinent to the circular economy. Moreover, we are crafting an Environmental, Social, and Governance (ESG) roadmap to provide suppliers with insights into their performance and guide them in aligning with EDP’s circular economy strategy.

The content of the training includes of 6 modules. The first ones focus on conceptual topics on Circular Economy, and the last ones in Circular Economy at the EDP group, targeting mainly the environmental area (EDP’s Circular Economy Strategy, Action Plans and CIRCUMETRIC evaluation tool). EDP Spain - Spain Partnerships for circularity improvement We engaged with and registered 18 qualified waste management organizations — and growing — to cover various materials recycling including the recycling and reuse of scrap metals, wind turbine parts and components including blades, packaging material such as cardboard and pallets, batteries from energy storage projects, as well as oils and associated lubricant waste from operations EDP Renewables – NA EDP gathers efforts to develop solutions so that its main waste materials can be used as by-products and raw materials for another industry, namely fly ash and coal slag which made up around 65% of the total waste materials recovered (256,689 tonnes). With regard to construction, operational activities and the maintenance of facilities, reuse is prioritized so that, when discarding, recycling is always considered as the first solution. In this way, contracts are established with licensed operators who transport the waste to the appropriate destination for recovery. Efficient waste management goes beyond the suitable disposal of waste and its incorporation into the economic circuit, by promoting its reintegration whenever possible. This management starts upstream, in design and in the choice of materials necessary for the functioning of operations.

In this sense, in 2023, EDP continued to promote efforts to provide greater empowerment and autonomy to its people through improvements in terms of the span of control and simplification of organisational layers in different Business Units, making it possible to increasingly decentralise decision-making and increase accountability. Considering the ongoing transition towards a business platform management model, the Key Performance Indicators (KPI) for 2023 were established and communicated to the entire EDP global population, with the respective results being communicated at the end of each quarter. To guarantee the group's global alignment and the speed with which commitments are delivered, the KPIs are defined annually based on EDP's organisational performance model, which is divided into three axes of action: Attractive Returns, ESG Excellence, Future-Proof People & Organisation. Efficiency and decision-making In 2023, the efficiency of the P&O and decision-making systems was also ensured with the implementation of various improvements that allowed for the reduction of more than 1.150 hours of work. These improvements are related to the follow-up of the three-year digital roadmap that aims to increase the digital maturity of people management processes which includes other achievements such as the implementation of a tool to automate and standardise the global workforce planning process, automation of the estimation of short-term incentives (STI) for all employees in Portugal, implementation of a new onboarding platform, standardisation of the recruitment process in a single tool and the construction of scorecards that allow the consolidation of employee data as a way of supporting decision- making by managers and P&O teams. Speed and efficiency are keywords for any future-proof organisation. In 2023 a new global decision-making model for EDP was approved. The main objective of this model is to improve the agility of decision-making processes, simplifying them and empowering employees. On the other hand, being a standardised global model, it speeds up the adaptation to an organisation structured by business platforms. The measures that are being taken to streamline decisions include focusing EBD interventions to the level of strategic definition and planning, increasing the approval autonomy of Management Teams in business situations, and providing the remaining levels with greater autonomy in operational decisions. Collaboration EDP continues to discover new opportunities to bring its people together through digital collaborative tools such as virtual global communities. Currently, EDP has already implemented eight global communities (Finance Ahead; ESG; People & Organization; Global Energy Management; Brand & Communication; Innovation; Digital; Generation), connecting more than 40% of the global population and providing access to content and initiatives in an innovative and customised way to each functional family. 3.4.6.3. Our heart People are at the heart of EDP's strategy, and this dimension of its global purpose reflects their importance and fundamental role in delivering the organisation's commitments to customers, partners, and communities. Recent years have led the EDP group to rethink its working models in favour of a more flexible and balanced working environment and to develop an active listening strategy highlighting the organisation's work in this direction. Organisational climate The organisational climate constitutes a fundamental, active-listening tool for monitoring different dimensions of employee experience, and the 2023 climate survey had the participation of 91% of EDP group employees. In terms of engagement, it was found that 80% of employees feel involved with the company, where the majority show pride in working for EDP (85%) and would recommend EDP as a great place to work (76%). Regarding empowerment, it was also concluded that 75% of employees have a high perception of organisational support, where 77% feel they can carry out challenging work, 72% believe that their skills and abilities are well used, and 75% feel they have the authority to make decisions necessary to do their job. 

107 Part I Integrated Annual Report 2023 Performance | Sustainability Rewards and benefits The work environment at EDP must also create global conditions of equality and recognition. Therefore, following its implementation in 2023, EDP's current global compensation framework was communicated to the entire population through different internal channels, contributing to a better understanding of how pay is determined, as evidenced by a 2% increase in the latest organisational climate results compared to the previous year. This framework, aligned with the best companies in the market, defines a common strategy and language for the entire group, allowing for global alignment and increasingly transparent communication. As well as clarifying the concepts associated with compensation through a global glossary for all EDP markets, this model makes it possible to define a range of job grades, map all the group's functions in a functional matrix and group them into organisational segments according to the level of responsibility, autonomy, impact on the company, level of knowledge and skills required. EDP globally assigns long-term incentive plans to the Top Management segment and critical positions in the Senior Management segment. The Executive Board of Directors (EBD) considers the attribution of these incentives as a tool for attracting and retaining talent, focusing on achieving results and complying with the business plan. In 2023, this global approach was also extended to the different benefits awarded to employees in the different markets where EDP is present, to define a common global offer complemented by local benefits. This framework was built over the year and is expected to be implemented in 2024. Flexibility and well-being In 2023, the global flexibility measures already implemented were consolidated, with positive employee feedback, as evidenced by the organisational climate results: most employees claim being satisfied with the hybrid working model (82%) and the Flex Fridays measure (83%), and say they feel productive in a hybrid working environment (95%). Throughout this year, continuity was also given to the global well-being strategy, based on five pillars (physical, social, professional, financial, and emotional). To this end, global awareness campaigns have been developed (e.g., Diversity & Well-being Moments; Mind Your Mind) to encourage the adoption of healthy behaviours, promote the accountability of the organisation's leaders, and remind all the channels and support helplines available. EDP believes work-life balance is fundamental to achieving more competitive companies and a fairer society based on flexibility, respect, and equal opportunities. To this end, EDP has once again been certified by the Fundación Másfamilia as a family-responsible company (efr, in its Portuguese acronym), a recognition awarded for the first time this year to the entire group. This certification, which the company has received since 2013, gained a global dimension this year, reinforcing the excellence of the various work-life balance measures that the EDP group promotes among its employees in all the markets in which it operates. Diversity, equality, inclusion and sense of belonging By ensuring fairness and inclusion for its people, EDP is also creating a more diverse working environment, and according to the organisational climate results, 85% believe all employees, regardless of their differences (age, gender, ethnicity, colour, disabilities, sexual orientation, religion), are treated fairly. Following the adoption of the DEIB (Diversity, Equity, Inclusion and Belonging) acronym and the revision of its global policy in the previous year, EDP continued throughout 2023 to promote different awareness-raising initiatives on inclusion issues and held the second Global Council at which the next strategic priorities were defined, with a focus on the inclusion of people with disabilities. Black connections “The aim of this programme was to strengthen, broaden connections, welcome, boost talents and enrich the journey of the 45 black professionals who took part in this training. During the journey we had the opportunity to reflect on the fundamental importance of valuing our struggle, which is constant and daily, to understand how significant our professional valorisation is, and above all, how much stronger we are when we are together! I'm very honoured and grateful for this journey! And very proud of everything we have already achieved, but persisting in what is yet to come." Wellington António 

108 Part I Integrated Annual Report 2023 Performance | Sustainability In 2023, efforts were made to ensure increasingly inclusive recruitment and the 2023- 2024 Gender Equality Plan was launched. This plan, developed annually, presents a set of measures (policies, programmes, incentives and benefits, initiatives, or projects) framed within the following dimensions: strategy, mission statement and values, equal opportunities, awareness and training, work-life balance, and partnerships for progress. 3.4.6.4. Our drive This dimension of EDP's global purpose reflects its ambition and leadership in making change happen as an organisation prepared for the challenges of the future. Talent attraction For EDP it is essential to develop a strong employer branding strategy that is increasingly global and attractive, which in 2023 meant continuing to review its employee value proposition to reflect the company's global positioning, purpose, and flexible, balanced, inclusive, and development-oriented culture. Overall, in 2023, the EDP group impacted more than 32,000 people through more than 140 initiatives and strong positioning on its main social networks, which resulted in more than 400 people-related content. This attractiveness strategy gave rise to more than 50,000 applications in EDP's different markets, resulting in 1,425 new hires and 677 internships, through an increasingly global, standardised, and digital recruitment process, which has been characterised by a strong investment in upskilling all the stakeholders involved to ensure a competitive position in the market, particularly in the energy market. In 2023, EDP also implemented its first-ever global onboarding experience and a new internal mobility program, demonstrating its commitment to attracting and retaining top talent. The global onboarding experience provides employees with a structured learning path that fosters a deeper understanding of EDP's business, brand, and people narratives, while also strengthening their contact networks. Meanwhile, the new internal mobility program empowers employees to explore a wide range of temporary and permanent opportunities worldwide, aligning with their development goals and presenting exciting new possibilities, resulting in more than 730 mobilities registered in 2023. These efforts resulted in several distinctions, such as a new recognition by the Top Employers Institute, highlighting the EDP group's strong positioning with candidates and employees and its dedication and commitment to attracting and retaining the best talent. Talent development and management In 2023, the first holistic assessment cycle was completed, evaluating past individual performance, current skills, and agility to face future challenges, following a global development model implemented the previous year. This cycle showed very high participation results, proving its importance for the development of each employee: 86% chose peers, 88% carried out their self-assessment, 91% carried out their assessment as managers, and 95% of employees confirmed that they had their development conversation. At the end of this year, a new assessment cycle began, with an improved user experience. Throughout 2023, efforts also continued to ensure the global development of EDP's leadership through an approach characterised by a focus on themes related to leadership, people management, culture, digital, innovation, safety, ethics, and compliance. The EDP group's total training volume in 2023 resulted in more than 375,000 hours of training, reinforced by worldwide access to on-demand content via Udemy, currently with 72% coverage. According to the organisational climate results, 76% of employees believe EDP provides learning opportunities, experiences, and tools to do their jobs in the best possible way. EDP’s succession planning is also crucial to ensure the continuity of the business, acting as an important people management tool. In line with the defined criteria, 150 successors and 457 potential career moves were mapped for 71 Top Management positions, as well as 694 successors and 1412 potential career moves for 346 Senior Management and Senior Consultant positions. Considering EDP's growth, the competitiveness of the market and the shortage of talent, several customised development initiatives were also carried out throughout the year, ensuring that most (80%) of top priority successors were involved in learning and development opportunities and contributing to the retention of more than 90% of the successors and their readiness to assume future roles. 3.4.6.5. A better tomorrow EDP's current strategy sets out ambitious commitments for the coming years, allowing it to become a future-proof organisation focused on providing a better tomorrow for current and future generations. In this sense, EDP's P&O strategy will continue to focus on meeting the challenges of attracting, developing, and retaining the skills needed to meet the challenges of the future, ensuring: • a global organisational design strategy that represents our global presence • enhanced digital maturity and efficiency of processes 

109 Part I Integrated Annual Report 2023 Performance | Sustainability • greater collaboration by strengthening our global communities • an inclusive and flexible working environment that promotes meritocracy • a strong employer branding strategy to attract the best talent • a learning and development-oriented culture that fosters accountability. With people at the heart of its strategy, EDP will continue to work towards an increasingly attractive, human, and meaningful experience for all its candidates and employees to drive a better tomorrow.

111 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.7. Supply chain 3.4.7.1. ESG challenges in supply chain management EDP’s materiality matrix identifies the supply chain and its management as one of the most relevant aspects for the company, based on its impact to society and for the business. Therefore, suppliers are a key stakeholder and also a main partner to achieve the company renewable installed capacity growth targets and sustainability goals. Technical excellence, execution performance, economic competitiveness, together with sustainability are the basis for EDP’s supply chain management. Sustainability in the supply chain faces considerable challenges arising from the increasing external pressure, both regulatory and market-driven, to implement ESG initiatives in the company’s operations. The transition to renewable energy sources and the reduction of emissions are crucial imperatives to address climate change. Simultaneously, ensuring ethical working conditions and promoting equity in the supply chain take on a heightened urgency, further emphasizing the need for increased transparency and regulatory compliance. The growing pressure from external stakeholders, encourage companies to collaborate with suppliers committed to high ESG standards, implement technological innovations for traceability (such as blockchain and AI), and adopt policies that incorporate ethical principles and human rights. 1 In 2023, this indicator was improved. Prequalification assessment already considers IDD, Environment and H&S, as well as other risk mitigation stages: desk assessments/audits/inspections, during contract period, and contract evaluation after contract closure. With this new approach, in 2023, 62% of suppliers are already compliant with ESG due diligence. 2 The volume of purchases associated with critical suppliers whose decarbonization, environmental (biodiversity and circular economy), and human rights goals are consistent with those of the Group is considered aligned with EDP's ESG objectives. In 2023, approximately 50% of the Group's purchasing volume is considered aligned with EDP's ESG goals. In this challenging scenario, the effective integration of ESG criteria into the supply chain allows EDP to improve management and risk mitigation, thereby contributing to the resilience of the organization in the global landscape. Supply chain – hot topics Given the dynamism present in the global ESG context, it becomes crucial to understand and adapt to ESG requirements by implementing strategies that involve data collection and regular engagement with stakeholders as a guarantee of future competitiveness. Navigating through new laws and priorities: As ESG risks grow in complexity and severity globally, laws are being implemented worldwide to ensure effective mitigation of these risks. Two recent and stringent laws, the U.S. Uyghur Forced Labor Prevention Act (UFLPA) and the German Supply Chain Due Diligence Act (LkSG), have important implications in case of non-compliance. Looking ahead to 2024, companies must prepare to face an evolving ESG landscape, adjusting practices and leveraging technology to meet compliance obligations while exploring opportunities to positively impact society and the environment. Alignment with the SDGs Objectives KPIs 2023 Target 2026 Suppliers compliant with ESG Due Diligence 62% 1 100% Volume of Purchases aligned with EDP’s ESG goals ~50% 2 90% 

112 Part I Integrated Annual Report 2023 Performance | Sustainability Stakeholder’s demand for greater transparency on ESG practices: Instead of relying solely on financial metrics for their investments, investors are now turning to ESG principles to assess companies' performance in sustainability goals. Similarly, consumers are increasingly interested in how companies ensure clear policies - including suppliers and downstream partners - that demonstrate their commitment to sustainability goals. The environmental agenda dominating overall concerns: Growing concerns about decarbonization of the supply chain and the transition to a circular economy pose significant challenges to suppliers. Therefore, organizations need to adopt more sustainable practices that will require changes in production processes. Compliance with environmental standards or certifications will become a market trend, and close collaboration with suppliers is essential to effectively implement decarbonization and circular economy strategies throughout the chain, thereby mitigating environmental impacts and promoting sustainability. The importance of sustainable procurement in a competitive market: Customers and investors care about the origin of products and the underlying ethics, leading them to question certain products or processes and demand assurances that goods were acquired responsibly with minimal harm, both directly through production activities and indirectly through the origin of raw materials, etc. Consequently, companies need to implement scrutiny processes and supply chain visibility to remain competitive in an increasingly dynamic global market. 3.4.7.2. Supplier management governance The Board of Directors directly monitors the procurement process management structures that implement the policies, being the ultimately responsible for ensuring that the company’s procurement policies and procedures are followed. EDP’s global procurement, qualification and process teams, and market-level operational teams at business units are responsible for managing suppliers from the bidding process through to their activities. Procurement teams have staff assigned to coordinate supplier relations with internal sustainability teams and supplier relations and engagement. At business unit level, Environmental and Health and Safety teams support and are in continuous liaison with the procurement teams to ensure that the company’s ESG priorities are considered throughout the contractual relationship with suppliers: tenders, construction, and operations. In addition, a permanent working group within the scope of sustainable procurement ensures that procedures are reviewed, updated, and reported, thus ensuring the day-to- day management of sustainability in the supply chain. The company has a set of policies and procedures that frame the entire sustainable procurement process across the group: • Supplier Code of Conduct that feeds into the purchasing and contract negotiation processes with suppliers to ensure the alignment of critical suppliers with the company's ethics and sustainability commitments • Sustainable Supply Chain Policy that establishes the principles and commitments to sustainability implemented along the purchasing process • Sustainable Procurement Protocol that defines the company's action protocol and due diligence process related to the supply chain. This Protocol Includes the identification of critical suppliers based on their activity with EDP. 3.4.7.3. Identification and mitigation of sustainable procurement risks EDP’s procurement process includes an analysis of potential risks that may occur throughout the supply chain, from risks that occur in upstream processes in the manufacture of equipment, to those that could occur in the company’s own operations and facilities. Procurement teams implement measures to mitigate technical, operational or ESG risks at different stages. The entire procurement and due diligence process specified below is intended to avoid and mitigate supply chain risks related to: • equipment efficiency risks due to poor manufacturing or maintenance • lack of supply due to supply chain disruption • possible risks related to ethics and compliance of the company partners • abolition of human rights risks such as forced labour or child labour, as well as other bad labour practices or lack of safety • environmental risks due to bad supply chain practices or lack of preparedness • other ESG and operational risks. 

113 Part I Integrated Annual Report 2023 Performance | Sustainability The risk management process is based on the EDP’s Sustainable Procurement Protocol, being critical suppliers those with high impacts and risks and therefore those for which engagement and additional measures should be prioritized. Therefore, through criticality analysis, the EDP group identifies and segments the potential risks associated with each type of specification. The analysis is carried out using a Sustainability Matrix defined in EDP’s Sustainability Protocol, which combines the relevant risks of the activity, identified by consulting stakeholders and attributable to the sector, with the characteristics of the specifications. Based on this internal process, the following criteria are considered in the analysis: financial, business relevance and continuity; dependence and autonomy; access to data; facilities; customers; local communities; cybersecurity; emissions potential; waste; environmental accidents; accidents at work; integrity and compliance; human and labour rights. Once the risks of each type of purchase have been identified, non-negotiable clauses are included in the specifications that establish the minimum qualifications standards that suppliers must meet, as well as the rules for monitoring execution of the contract. Suppliers that submit proposals only enter the negotiation phase after a thorough ESG due diligence is carried out, including integrity, legal and ethical, financial, technical, social and environmental compliance. Through the application of go/no-go rules in the selection of suppliers and contractual clauses that include monitoring, audits, and performance assessment, EDP ensures that it works with low-risk suppliers with skills appropriate to each activity´s inherent risks. Traceability and indirect risks During 2023, EDP has taken a step forward in terms of equipment traceability. Traceability has become a fundamental element for the company to avoid the emergence of risks in the supply chain, being a key tool to: • ensure a clean supply chain and avoid human and labour rights abuses • be able to measure the environmental impacts generated by the transport of equipment • comply with regulatory requirements, such as Uyghur Forced Labour Prevention Act, Corporate Sustainability Due Diligence Directive (CSDDD), Corporate Sustainability Reporting Directive (CSRD), Carbon Border Adjustment Mechanism (CBAM), among others • being able to avoid a disruption of the supply chain due to international conflicts • comply and respond to stakeholders demands such as investors and offtakers. Traceability has become a key element in the engagement with the suppliers of the main equipment, becoming a tool that allows the origin of the equipment to be tracked during the phases, until the development of the final product that it is supplied. To tackle this challenge, the company is creating a working group that involves the key teams in this process, to ensure that all the knowledge is available for the development of a traceability tool. This group has already started developing internal traceability protocols based on international frameworks developed in the main markets in which it operates. 

114 Part I Integrated Annual Report 2023 Performance | Sustainability Therefore, traceability it is now a main part of the engagement process with suppliers when providing the company with the project traceability map and when they must comply with the specific protocols for equipment. All these topics have become a common element in the engagement and contractual negotiation with its equipment suppliers. Sustainable Procurement Process EDP’s procurement process extends to direct and indirect suppliers and allows to establish practices and procedures that ensure a high-quality relationship with the company’s suppliers and sustainability practices through the entire supply chain. Some of these practices and procedures are: • development of activities that promote the exchange of sustainability best practices in procurement processes; • contribution to the growth and profitability of the business through the promotion of initiatives for the progress and continuous improvement of the supply chain • systematic monitoring of suppliers’ performance and risk profile • dissemination and implementation of EDPs ESG policies (Environmental, H&S and Human and Labour Rights policies and Code of Ethics) in the acquisition of goods and services • involvement and empowerment of all actors in the supply chain. These practices are only possible through continuous dialogue and engagement with suppliers where the main priorities of both parties are shared at the technical, implementation and ESG levels. EDP assesses human rights violations that may be related to any counterpart, particularly on the electric power sector supply chain,where rely the critical suppliers for EDP., A Due Diligence process on legal compliance, integrity, human and labor rights is carried out for counterparts with businesses exceeding €25,000. In accordance with specific risk maps, there is a thorough analysis of climate and environmental issues, management practices, qualifications, sustainability, financial and business continuity risks, cybersecurity, safety prevention and management, quality, among others. Once the contractual relationship is established, with ESG requirements being converted into contractual clauses, EDP monitors, audits, and evaluates the performance of its critical suppliers. Uptoday, the Due Diligence process has been mainly focused on contracted or yet-to-be- contracted suppliers. although EDP is extending this Due Diligence to indirect suppliers. Auditing suppliers of suppliers is an emerging issue on the international agenda - it requires time and a mindset shift, as well as collaborative work between companies. EDP is currently addressing this issue through discussions with its key suppliers exposed to ESG risks, modifying clauses in its specifications, requesting equivalent commitments, and developing the principle of independent auditing. Therefore, EDP has in place requirements related to ESG, Quality and Risk management that have to be met by its suppliers throughout the main procurement phases aligned with the due diligence process: 1. Registration and Qualification, 2. Requests for Proposals and Contracting and, lastly, the 3. Monitoring and Evaluation of the suppliers. ESG due diligence layers 

115 Part I Integrated Annual Report 2023 Performance | Sustainability 1\. Registration and Qualification The registration process is a mandatory requirement for any company who intends to become a supplier or apply for a qualification process. EDP’s corporate System of Supplier Registration supports supplier’s selection by providing detailed information, validated and updated by credible sources, in order to guarantee their accreditation through financial, technical quality and ESG criteria. EDP’s qualification process aims to provide an analysis on critical issues and establishes minimum requirements to ensure that the suppliers score positive in: technical capabilities & quality management, financial & risk, compliance & integrity, health & safety and environmental management criteria. The company regularly reviews and reassesses the Qualification System criteria to ensure that they reflect the main market trends and regulations and that a high level of quality of the information available from suppliers is maintained. In addition, during the Qualification Process, the company shares relevant information that suppliers must comply with: EDP Code of Ethics, EDP Integrity Policy and EDP Supplier Code of Conduct. Other policies and requirements are also shared with the suppliers depending on their activity with the company and the phase where they are involved (manufacturing or operational services). The qualified suppliers are then able to participate in the EDP’s bidding and contracting process, during the qualification validity period. 2\. Requests for Proposals and Contracting The incorporation of adequate criteria in the contracting processes is essential to ensure in-depth management, mitigation, and avoidance of operational and ESG risks in the supply chain. In 2023, EDP has updated its additional analysis on 5 ESG priorities - decarbonisation, circular economy, human and labour rights, health and safety, and transparency and biodiversity - in its tenders (RfP and other processes) for strategic renewables’ equipment purchases. At this stage, EDP analyses suppliers’ policies, targets, strategies, statements, roadmaps and other documents or procedures that show their alignment with EDP’s positioning. This analysis also helps the company to identify potential ESG risks. During this phase EDP also performs specific meetings with suppliers to understand their strategies, measures and policies regarding EDP’s ESG main priorities. Adequate compliance by all EDP suppliers with applicable H&S and environmental requirements is essential to guarantee the correct performance of the contracted services and works. The company has also a disciplinary and sanctioning regime, which is included in some of the RFPs, contracts, and purchase orders so any provider will be always informed about the consequences of not complying with EDP’s H&S and Environmental requirements. Moreover, EDP has a Third-Party Integrity Due Diligence Procedure to reinforce risk identification and prevent possible integrity or corruption risks for EDP in the relationship with third parties. In high-risk situations, it is necessary the approval of the Management Team, its submission to the Executive Board of Directors, and the execution of additional recommendations to the inclusion of the compliance clauses in the agreements, related to corruption, conflict of interest and the inclusion on sanctions lists. During the contracting and awarding phase, the company establishes a fluent dialogue and shared of information with strategic suppliers through specific meetings. Through these meetings EDP and its partners discuss technical and sustainability criteria that are fundamental for the fulfilment and execution of the projects. During 2023, EDP has taken a step forward in the contractual negotiation with suppliers regarding ESG requirements been requested. Depending on the type of equipment or service, EDP establishes a series of contractual requirements to address any material issues during execution. 3\. Monitoring and Evaluation In order to guarantee suppliers’ compliance with the previously mentioned requirements, EDP monitors critical suppliers during their services delivery and activity in the group’s facilities. EDP has two mechanisms to ensure compliance with contractual obligations, passive mechanism and active mechanism: • The passive mechanisms are those related to suppliers’ report on of any situation, infringement, or circumstance that may affect the agreement 

116 Part I Integrated Annual Report 2023 Performance | Sustainability • The active mechanisms consist in physical audits; inspections; management systems implemented by EDP certified and supervised by verified external certification bodies (third parties). Valuing ESG Criteria in Supplier Selection ESG criteria are technical specifications that suppliers must demonstrate to be selected for the negotiation phase. The definition of the required ESG criteria is established at two levels: • as minimum contractual conditions applicable to all purchase contracts • as specific conditions for certain types of contracts, depending on pre-identified and relevant risks. These specifications are go/no go criteria. For example, for a contract exposed to workplace accident risks, the supplier must demonstrate the existence of a certified management system, including the qualifications of its employees, and report accident indicators below a set limit. Applying minimum weight to ESG criteria in procurement through the go/no go mechanism, based on thresholds, ensures that ESG criteria are non-negotiable. In some situations, such as market shortage, dependence on certain specific technologies, or low qualification of suppliers, given the defined ESG goals, proposals are ranked according to a criterion-by- criterion scoring system, and an exception may be approved. For all intents and purposes, through the ESG matrix, these cases are pre-identified. These situations are closely monitored, and suppliers are excluded from contracting if they fail to meet the minimum ESG requirements within a specified timeframe. Purchases Main Risks and Segmentation There are four segments of ESG risk in the supply chain that correspond to various purchasing categories in the value chain. • Electrical/Industrial Equipment: EDP does not develop, design, or manufacture any type of equipment, directly or indirectly. The procurement of equipment’s is directed towards finished technologies, in wholesale, ready for installation, which must meet pre- defined technical and sustainability specifications. For each type of technical equipment, the number of manufacturers is small, resulting from previous specifications and requirements. • Technical Services and Construction: technical and construction services are directed to local suppliers and include both preparatory work for the installation of infrastructure and the actual installation of equipment and technologies. Often, the same suppliers are responsible for maintenance work. This type of activity is based on direct service providers and, depending on their expertise, includes subcontracted providers. EDP qualifies not only contractors but also subcontractors. • Corporate and IT Services: these services are developed by service providers under medium/long-term outsourcing contracts. These activities have a low level of direct equipment and energy consumption since they are office extension and local logistics activities. The exception is data storage and management. • Fuels: consists of a small number of coal suppliers, usually around 10, and will remain in the portfolio until 2025 at the latest when EDP closes the last coal-fired power plant. Additionally, natural gas suppliers will be in the portfolio until 2030 when EDP will terminate all thermal activities.

117 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.7.4. Supply chain engagement The EDP group acknowledges the importance of partners in advancing sustainability goals and the mutual success of both parties. Through the EDPartners program, EDP aims to enhance partner success by promoting the exchange of best practices, initiatives, and project development. The program focuses on aligning processes for excellence, recognizing positive practices, identifying areas for improvement, and building trust to positively impact society and improve the long-term supply chain. Two significant initiatives have been developed under the EDPartners program: • EDPartners Talks: This initiative fosters open and constructive dialogue with strategic partners, facilitating informal conversations to gain insights into EDP's operations and strengthen understanding and proximity with key partners. It involves specific questions about EDP's competitive advantages, strategic plan, communication channels, negotiation processes, innovation in procurement, and potential difficulties of becoming an EDP supplier. The initiative aims to continually improve collaboration, promote innovation, and strengthen sustainability throughout the supply chain. It involves 15 suppliers from all procurement categories. • ESG Talks: This initiative focuses on promoting sustainability analysis and identifying the ESG maturity of key suppliers through sharing sessions. It aims to identify actions for sustainable purchasing and focuses on critical partners with management systems for decarbonization, human and labour rights, circular economy, biodiversity, and health and safety. The initiative explores market drivers in the ESG context, peers' investment in meeting ESG requirements, and parameters for more sustainable products for EDP's future needs. The goal is to accelerate ESG maturity in the supply chain through concrete initiatives and improved communication on ESG issues. It involves 10 suppliers from critical materials such as cables, solar panels, and IT. Cumulatively, EDPR performs an engagement process with its strategic suppliers throughout its relationship with them, from qualification to the beginning of the service or delivery of equipment, including contractual negotiations: • During the qualification, the company has conversation with the suppliers and contractors to request information and analyse them regarding to the following criteria: Technical; Compliance; Environment; H&S and Financial. • During the RFP and contracting phase, it requests additional information from the shortlist of suppliers that can be awarded, with additional technical information, as well as information related to the suppliers' ESG performance and practices. • In addition, in the contracting phase, EDPR has continuous conversations and meetings with suppliers to negotiate and include clauses of different types that ensure the execution of the contract and are in line with the company's standards. • During the execution of the contract, depending on the type of supplier and the service offered to the company, the engagement will be different, through conversations related to the manufacturing process of the equipment to the control, coordination and monitoring of the installation and maintenance processes in the facilities. 3.4.7.5.

Safeguarding the health and safety of employees (both inside and outside the group), suppliers, contractors, customers and stakeholders, is a priority. For the group, no situation or emergency can justify endangering a person's life! In fact, EDP guides its action in this matter by the principles established in the Health and Safety at Work Policy, a binding document that covers all group employees and contractors, making the entire hierarchical structure responsible. To this end, the EDP group requires everyone to adopt practices in line with the principles of this policy, in order to ensure continuous improvement. Safety practices The implementation of EDP's annual occupational health and safety programme was based on a set of actions aimed at preventing occupational accidents, as measured by a reduction in the frequency rates and the seriousness of accidents and occupational illnesses, and included training for EDP employees and contractors, the ongoing evaluation and control of labour risks and the implementation of an internal and external inspection and audit programme of EDP facilities and works. The plan of strategic Occupational Health and Safety (OHS) objectives contains the repository of commitments and initiatives undertaken by the different organisational units for the execution of the six vectors of intervention defined on a strategic and corporate level, concerning OHS approved for 2020/25: (1) commitment of leaderships to OHS; (2) behaviour, preventive activities and learning from mistakes; (3) streamlining, digitalising and standardising OHS processes in the EDP group; (4) skills; (5) communication and involvement; (6) management of OHS in the contracting of ESP. With regard to emergency preparedness and response, 537 simulated drills were carried out throughout the EDP group, covering various industrial, administrative and construction sites, in order to test the effectiveness of the planned response capacity in potential emergency situations. These drills included the participation of the civil defence force, the fire brigade, police and public safety authorities, as well as employees, contractors and the surrounding communities. In order to prevent electrical accidents involving third parties not involved in the group's activity, EDP ensures that the risks associated with its facilities and equipment are identified and communicated. However, in 2023 there were 47 accidents of electrical origin with third parties, which resulted in the deaths of 15 people. These accidents were the result of civil construction activities, tampering with the grid and leisure, among others. Safety indicators The Health and Safety at Work Policy within the EDP group demonstrates its commitment to a model of Health and Safety Work Management based on continuous improvement and the conviction that working in a safe, healthy environment is instrumental for employee satisfaction and provides added value for successful results. To improve management of the Policy objectives, EDP has a Corporate Safety Management System based on ISO 45001:2018 and the ILO-OSH 2021 recommendation. This system can be adopted in its entirety by each of the companies, or, alternatively, taken as a reference for the implementation of their own systems. In 2023, the EDP group counted a total of 10,255 employees covered by ISO 45001:2018 certification. The certification covers 92% of net installed power in production activities. Audits, inspections, visits and observations 52,573 Training EDP workers and ESP 392,211 h 

119 Part I Integrated Annual Report 2023 Performance | Sustainability In EDP group, 177 work-related accidents with lost days, occurred out of all EDP employees and ESP, representing an increase of 33% compared with 2022. The frequency rate (FR) amongst EDP employees and ESP in 2023 grew 13% compared with the previous year, consequently we were unable to achieve the target of 1.64 set for 2023. During 2023, there were five fatal accidents at work with contractors (fall from height, electrical origin, Impact with objects and fallen objects). Additional information visitwww.edp.com. Frequency rate (Fr) Severity rate (Sr) Accidents that occurred due to interaction with objects are responsible for 36% of accidents, followed by incorrect movements or overexertion, falls from a level, and electrical causes with 13% each, 8% of which were falls from a height, while the remaining causes accounted for 17%. Tipology of accidents at work (%) Health promotion The health and well-being of the group's employees are promoted and protected through compliance with occupational health monitoring requirements, in accordance with applicable legislation. Health monitoring programmes guarantee fulfilment of the regular medical examinations plan, workplace inspections, participation in the Occupational Health and Safety and Internal Accident Prevention Committees, and the implementation of a range of preventive campaigns. During 2023, 10,436 medical exams, 1,940 consultations with employees who have nutrition programmes, 1,973 cardiovascular screenings and 2,841 vaccination programmes against influenza, pneumococcal infection, hepatitis B and yellow fever, which covered 1,418 employees, were carried out in the EDP group. Also, within the scope of occupational medicine activities, 398 screening sessions for alcohol and drugs were carried out. EDP group monitors and follows up the occurrence of occupational diseases. In 2023, no cases of occupational illness were recorded. 337 73 69 81 425 753 749 592 2020 2021 2022 2023 EDP Contractors 0.77 0.92 1.13 1.47 2.12 2.09 2.18 2.32 2020 2021 2022 2023 EDP Contractors 13% 8% 13% 6% 36% 3% 13% 1% 6% Electrics High level falls Lower level falls (include same level falls) Earth covers/Splints Interaction with objects Road Accidents Incorrect movements/overstress Fire/Explosion Other 

120 Part I Integrated Annual Report 2023 Management Report | Social capital EDP Group employees showed adequate stress and well-being when carrying out their work and can be considered to be carrying out their activity in a healthy working environment. Differentiator factor: Until 2018, this assessment was carried out in the sphere of EDP employees in Portugal, due to the fact that it was a legal issue. In 2019, the pandemic we are experiencing challenged our routines and our people-focused corporate culture. The EDP Group therefore wanted to extend this Psychosocial Risks and Well-being assessment to all the Group's employees. What lies ahead: In 2025 a new Psychosocial Risk Assessment will be carried out in all the Group's geographies. Psychosocial risks Work-related psychosocial risks have been one of the major challenges associated with Safety and Health in the workplace, and are directly linked to problems such as stress, violence, harassment, burnout and engagement. Our approach: The Prevention and Safety area once again signed a protocol with the Faculty of Psychology of the University of Lisbon to draw up an "Assessment of Psychosocial Risks and Well-being" across all the busi- ness units and geographies where we operate, with the exception of APAC. Between June and July 2023, em- ployees were invited to respond online, and the response rate was very positive. The aim of the ques- tionnaire was to identify the factors associated with the appearance of both stress and well-being, as well as to establish intervention guidelines for building a safer and healthier working environment. Main conclusions: The results indicate stability compared to 2021, with the majority of risk and protective factors remaining unchanged. The absence of overwork, role conflict and job insecurity stand out, as does the presence of a positive social climate and support from colleagues and bosses. However, around 32 per cent of workers feel that the company does not look after their well-being, highlighting the need to develop practices to promote well-being. Furthermore, the adoption of a hybrid teleworking model is well received by workers, bringing advantages for the company, team and individuals.

Crisis management Alignment with the SDGs Objectives KPIs 2023 Target 2026 BitSight rating 810 ≥740 Climate change adaptation plans implemented 50% 100% Organizations face, nowadays a multiplicity of adverse situations, as a result of their international positioning, further exposing them to disruptive events with potentially high negative impacts. On the other hand, being aware of its position allows organizations to assume a state of continuous monitoring and alertness, regarding the evolution of possible crises on a global scale, with impact on the organization. The EDP group assumes crisis management as a strategic capacity that enhances its supported and sustainable response to abnormal situations, characterized by high uncertainty and with potential negative impact on its strategic and business commitments and objectives, requiring urgent attention and action to protect the life and physical integrity of people, the environment, assets, and the reputation of the EDP group. The EDP group Crisis Management Plan (OS 4/2021/CAE), which is transversal and strategic in nature and aligned with the ISO22361 standard, establishes the management structures, guiding principles for decision making, and practices to be observed in the three phases of the crisis management process: before, during and after the crisis. Alongside the Crisis Management Plan, the Crisis Communication Plan was established, which supports the actions of the teams responsible for ensuring effective communication - transparent, coherent, and consistent - in these highly complex and volatile contexts. Designed to allow a strategic response to crisis and pre-crisis situations of diverse natures and with different levels of complexity, these plans are echoed in the Business Units and Corporate Centre Departments, when applicable, ensuring the tactical and operational capacity to respond to Crises, and an adequate escalation to the EBD and the EDP group's Crisis Management Office. In order to strengthen its resilience, the EDP group established, in the OS 15/2023/CAE and OS 16/2023/CAE, its Business Continuity Policy and approach to Business Continuity Management, respectively, also specifying the methodological parts to be observed, in alignment with the ISO 22301:2019standard, strengthening its ability to detect and respond appropriately to risks with potential impact on its activity. It should be highlighted that E-REDES has maintained an ISO 22301 - Business Continuity certification since 2015, while EDP REDES España has accomplished its certification against this standard, in 2023. EDP has therefore developed and maintains a set of human, procedural and technological controls, and safeguard measures that have been improved overtime, complemented by recovery plans at an operational level, such as the Business Continuity Plans for priority processes/services, Contingency Plans or Disaster Recovery Plans, among others. These allow EDP to enhance its capacity to continue to provide its services at acceptable levels even when faced with incidents, emergencies, and disasters, fulfilling its purpose and meeting the objectives it has committed to. To ensure their effectiveness and adequacy, these plans are subject to periodic exercises and simulations, both internally and in collaboration with external entities relevant to EDP's value chain. Also noteworthy was the creation of the Safety, Security & Business Continuity Unit (SSBC) in January 2022, which allowed for the strategic reframing of the Crisis Management and Business Continuity, Safety (prevention and security) and Security (physical security and duty of care) subjects, towards a holistic and transversal management of these in EDP, benefiting from the clear complementarity between them and from an integrated approach. Aiming to strengthen this commitment, the EDP group has defined the Security Policy (OS 8/2022/CAE), which establishes the guiding principles to be followed by all Business Units and Corporate Centre departments. Monitoring the evolution of geopolitical conflicts Since February 2022, following what was established in its Crisis Management Plan and Crisis Communication Plan, EDP assumed a Pre-Crisis Situation, motivated by the emergence of the Russia-Ukraine conflict, which resulted in a worsening of geopolitical instability in Europe and worldwide. Starting an intensive follow-up of the evolution of this situation, a monitoring group was established that included different areas of the Corporate Centre of EDP, S.A., and the Business Units, especially those with a greater presence in the nearby region. This monitoring is carried out in terms of topics such as the physical safety of people and assets, 

122 Part I Integrated Annual Report 2023 Performance | Sustainability cybersecurity, business continuity, risk management, supply chain, energy management, finance, regulation and stakeholders, compliance, communication, and social support. This monitoring group, under the coordination of the SSBC Unit, is responsible for reporting to the EBD on the main risks existing at each moment, changes in the environment, the status of implementation of risk management measures defined, as well as further measures proposed for adoption. The presence of EDP Renewables and, more recently, EDP Comercial in countries bordering the conflict zone led to the adoption of a series of immediate measures to safeguard its people in these regions and the EDP group's people from Ukraine and Russia who are in other operations, as well as its assets under construction and in operation, including Evacuation Plans. As a complement to the analysis and monitoring of the situation by the different areas, EDP also opted to resort to entities specialized in the management of geopolitical conflicts, in order to acquire greater knowledge of potential developments and thus anticipate its response to potential risks or threats Considering the possible scenarios of the evolution of geopolitical conflicts (including, among others, the situation in the Middle East), an approach to evaluation of the most relevant risks and impacts for EDP was adopted, as well as of the main risk management and impact mitigation measures. Critical infrastructures Council Directive 2008/114/EC defines "critical infrastructure" as "the asset, system or part thereof located in Member States which is essential for the maintenance of vital societal functions, health, safety, security, economic or social well-being, and the disruption or destruction of which would have a significant impact in a Member State as a result of the failure to maintain those functions". EDP is responsible for a set of critical infrastructures in Spain and Portugal, which include electricity generation and distribution infrastructures (physical and control facilities), as well as related customer service activities, which have been identified within the scope of the transposition of Council Directive 2008/114/EC into Spanish and Portuguese law. It should be noted that a new European directive was recently approved, Directive (EU) 2022/2557 of the European Parliament and Council of December 14, 2022, on the resilience of critical entities (repealing Council Directive 2008/114/EC with effect from October 18, 2024), which is awaiting transposition into national law. Due to the diversity of the critical infrastructures under its responsibility, EDP has proactively adopted strategies to respond to risks of different natures, such as physical risks (e.g., fires, earthquakes, atmospheric events, including extreme events), and technological risks (including, but not limited to, cybersecurity risks for operational systems and information systems). In addition, the measures and tools adopted to mitigate these risks are diversified and different in nature, adjusted to the specifics of the infrastructures, necessarily covering physical security (safety and security aspects), technological security and cybersecurity, as well as the management of business continuity, leveraged by a strong component of training and exercises. EDP has developed, for each of the critical infrastructures, the respective security plan, supported by the conclusions of the risk analysis carried out and the set of measures implemented as a result, in line with the provisions of Council Directive 2008/114/EC and in alignment with the national legislation DL 20/2022 revoked (DL 62/2011). Furthermore, it is important to mention the role assumed by EDP in promoting the adoption of good practices in the management of critical infrastructures in the sector, through its dissemination, but also through collaboration with external entities, participating in exercises and workshops relevant to the topic. Focusing on establishing and developing a Security Culture, EDP promoted a set of awareness-raising activities, provided by SIS - Security Information Service; (i) the Knowledge and Sensitive Information Protection Program, which aims to alert entities in Portugal to espionage threats and raise their awareness of the importance of protecting knowledge and sensitive information and (ii) the Krítica Program, with the aim of contributing to improving the protection of critical infrastructures and sensitive national points against the terrorist threat. Also, with the aim of promoting a culture of resilience at EDP, the SSBC dedicated a month to the dissemination of good practices and strategies to be adopted in natural disaster scenarios, in particular, earthquakes. Highlights among the initiatives promoted were: EDP’s participation in the annual seismic risk awareness exercise "A Terra Treme", the organization of the conference "Resilience | Connecting the dots between entities", with the participation of the National Emergency and Civil Protection Authority and of the Lisbon City Council, through its ReSist program, and a workshop in collaboration with the Southern California Earthquake Center, focusing on good practices to adopt for earthquake preparedness and response. Furthermore, with the aim of promoting a culture of resilience at EDP, the SSBC dedicated a month to the dissemination of good practices and strategies to be adopted in natural

Highlights among the initiatives promoted were: EDP’s participation in the annual seismic risk awareness exercise A Terra Treme, the organization of the conference Resilience | Connecting the dots between entities, with the participation of the National Emergency and Civil Protection Authority and of the Lisbon City Council, through its ReSist program, and a workshop in collaboration with the Southern California Earthquake Center, focusing on good practices to adopt for earthquake preparedness and response. Furthermore, in this context and following the approval of the Sendai Framework for Disaster Risk Reduction 2015-2030, EDP has participated, in Portugal, in the National Platform for Disaster Risk Reduction (PNRRC in its Portuguese acronym), under the responsibility of a sub-committee coordinated by ANEPC (National Authority for Emergency and Civil Protection). We highlight EDP’s participation in the development of the Handbook on “Sectoral Interdependencies in the Resilience of operators of essential services to society” as part of the PNRRC activities for the 2021-2023 (soon available on the PNRRC website), while during the 2015-2017 triennium, the "Good Resilience Practices for Critical Infrastructure - Private Sector and State Business Sector" was developed and made available at the PNRRC website. Information security The EDP group's Information Security Policy, updated and approved by the Executive Board of Directors in 2023, establishes information security as a competitive factor, generating confidence in its stakeholders, but also as a critical responsibility in a social context, due to its role as an operator of critical infrastructures and manager of large volumes of personal data on customers and employees. The governance of information security in the EDP group underwent an evolution during 2023, with the Executive Cybersecurity Committee now taking place every quarter to: • set guidelines for the strategic planning of information security • assess the company's cybersecurity risks • monitor scenarios of serious incidents in the energy sector and the organization's cybersecurity risk profile. The EDP group's cybersecurity risk is presented annually to the members of the General and Supervisory Board. Cybersecurity in 2023 in the EDP group The global cybersecurity landscape has become more challenging, with increased geopolitical tensions posing greater threats to critical infrastructures and with the energy sector remaining a prime target for attackers. Despite this context, the EDP group's cybersecurity teams were able to: • approve of the evolution of the group's cybersecurity governance model • expand the global SOC (Security Operations Center) • eliminate legacy communication protocols vulnerable to cyberattacks. Despite the increase in cyber threats and incidents compared to the previous year - largely due to the expansion of the attack surface resulting from the expansion of the organization's operations –, no incidents with a significant impact on either the EDP group's image or its operations were registered. Cybersecurity activities and indicators The Cybersecurity rating adopted – defined as the group's KPI for this area –, observes the EDP group's behaviour in cyberspace. During 2023, the rating remained at the advanced level, with an average of 810 points, well above the average for the sector. To support the challenge secure operations in EDP's energy networks and facilities, a "Zero Trust" strategy for cybersecurity was adopted, comprising a plan of initiatives for the years 2021-2023, both in the domain of networks and IT systems and in the OT domain. These plans are currently being executed. Regarding face-to-face training, highlights include the EDP Cyber Range, providing a learning model based on gamification. In 2023, more than 14,000 online courses were completed, and 586 employees took part in face-to-face or online training. EDP continues to position itself as reference in the use of best practices in the area of information security by participating in several national and international work/study groups, as well as European projects with other European counterparts, academia and governmental organisations.

Voluntary investment in the community EDP group’s social investment – strategic vision The EDP group actively contributes to the sustainable development of the communities in which it operates worldwide, through its own social investment and collaborative initiatives, donations and volunteering. As social impact is a strategic pillar of the EDP group, these initiatives aim to meet social needs in line with the group's core themes, namely investment in fair energy transition projects which should represent around 45% of investment by 2025. The Fair Energy Transition projects include support for energy access, energy inclusion and communities impacted by the closure of thermal power plants, projects aimed at protecting natural heritage and biodiversity and also projects promoting energy efficiency and renewable energies, contributing to decarbonisation and combating climate change. On the other hand, the group's social investment strategy is also based on Culture, with the mission of promoting access to culture, stimulating art and protecting cultural heritage. Cultural projects are projected to represent around 30% of investment by 2025. In parallel and recognising the need to continue to support projects that respond to other social needs in the communities where EDP is present, part of the annual budget is earmarked for investment in various areas, such as training, health, social inclusion and response to emergency situations, among others. These Pillars are aligned with the Social Investment Policy.

126 Part I Integrated Annual Report 2023 Performance | Sustainability Voluntary contributions – application of the B4SI methodology EDP uses the international methodology B4SI \- Business for Societal Impact to characterise and assess its voluntary investment in the community, which accounts for most of the investment made in this area (97%). This model promotes alignment between the purpose of companies and social needs, facilitating the structuring of priorities and reflecting on their results and benefits for the communities. In 2023, according to the B4SI methodology, voluntary investment in the EDP group's communities was 33.1 million euros, supporting the projects of 604 entities, resulting in 3.1 million direct beneficiaries. Of this investment, 91.7% was classified as community investment, 8.2% as charitable gifts and 0.1% as commercial initiatives. Cash contributions were the main form of contribution (65%), followed by in-kind contributions (33%) and time contributions (2%). Time contributions, equivalent to 570 thousand euros, correspond to EDP volunteering initiatives carried out during working hours. Investment in Education was primarily directed at skills development projects, namely training (upskilling and requalification) in renewable energies to respond to future labour needs, as well as educational programs for new generations to understand the importance of renewable energy. Investment in Health was directed at supporting health institutions and health professionals (equipment, support for health research, among others). Investment in Emergency Relief was mostly aimed at supporting local organizations that aim to guarantee the safety of populations in the event of emergencies, such as fire brigades and humanitarian organizations in the context of the earthquake that occurred in Turkey and Syria. Investment in Economic Development gave priority to energy access projects for communities without access to the electricity grid, with the A2E Fund standing out and support for entrepreneurship and job creation projects. Projects for social inclusion and fighting energy poverty contributed to the investment in Social Welfare, promoting the improvement of thermal comfort and living conditions for several families. Voluntary investment in the Environment was carried out through projects to promote biodiversity, decarbonization, and climate change awareness-raising. In turn, investment in Arts and Culture gave priority to projects providing access to art and culture, and those preserving and promoting cultural heritage.

These types of contributions correspond to support for projects resulting from counterparts, commercial/legal impositions or compensatory measures. In 2023, the mandatory investment in the communities of the EDP group was 1.1 million euros (3% of total investment in the community) supporting 18 entities. Although with less weight than voluntary contributions and not recognised by the B4SI methodology as social investment, these contributions promote the sustainable development of the communities where EDP operates and, at the same time, are an important instrument to obtain the social license to operate in territories where new EDP infrastructure is to be built or new markets where EDP begins to operate. Contribution to the SDGs In addition to contributions through its operations/business, the EDP group also contributes to the Sustainable Development Goals (SDGs) through its social investment programmes, prioritising goals 5, 7, 8, 9, 11, 12, 13, 15 and 17, in accordance with the Social 

127 Part I Integrated Annual Report 2023 Performance | Sustainability Investment Policy. EDP reports its contribution to the SDGs not only at the level of the SDG objectives and targets, but also at the level of the indicators set by the United Nations. Additional information regarding EDP’s contribution to the SDGs can be found in chapter 2.5. In 2023, of all the voluntary contributions recognised by the B4SI methodology, EDP supported projects that contributed to the SDGs with an investment of 14 million euros (43 % of total voluntary contributions) , resulting in 1.8 million direct beneficiaries. In turn, through mandatory contributions, EDP supported projects that contributed to SDGs with an investment of 1 million euros (92% of total mandatory contributions).

The Volunteering Program’s areas of intervention are aligned with the EDP group's Social Investment Policy and focus on social inclusion, empowerment, energy inclusion, biodiversity and climate action. Over the years, the Volunteering Program has attracted a growing number of participants, because it allows the allocation of working hours to the various initiatives, reinforcing the important role of volunteering for the EDP group, as well as its visible impact on everyone involved. The aim is to achieve a 30% share of the EDP group's Headcount (HC) by 2024. In all the different actions and projects promoted throughout 2023, 4,426 unique volunteer employees participated (34% of the company's HC), contributing 21,591 hours during working hours and 4,887 hours outside working hours. Given the inclusive nature of the Volunteering Program, 585 EDP Friend volunteers (company retirees, friends, family and partners) were also involved, contributing 1,274 volunteer hours. In total, in 2023, the EDP group Volunteering Program involved 5,011 volunteers, making a total of 27,752 volunteer hours. In 2023, the main focus of the Volunteering Program was to strengthen training projects, in particular with children and young people, volunteers and leaders and social organizations, while continuing to provide an effective response to the main challenges identified in the volunteering strategy defined for 2022- 2025, in particular, communication, recognition of volunteers and raising awareness among leaders on the subject of volunteering, as well as working towards increasingly involving different stakeholders in the initiatives promoted and working on empowering communities, in particular with the 2nd edition of Energy Week, in Portugal. In this initiative, EDP dedicates a week to a community outside large urban centres, rehabilitating a space that serves the community (in partnership with the NGO Just-a-Change) and carrying out various activities, from energy classes to ateliers or workshops, environmental actions, among others, involving the entire population, from the youngest to the senior population. Additionally, and following the trend of recent years, skills volunteering has been gaining more and more ground, putting employees' talents and know-how at the service of the community, and in 2023, topics such as fair energy transition, social entrepreneurship and ESG themes began to gain more prominence in this field. In 2023, worthy of mention was the 9,034 hours in skills-based volunteering projects (34% of total volunteer hours) carried out by EDP employees, of which 7,316 hours took place during working hours. 

128 Part I Integrated Annual Report 2023 Performance | Sustainability 2023 was also a year of great achievements regarding the Volunteer Program as a global program. On May 25th, during the Energy Campaign, the first Global Volunteer Action was launched under the motto – Move your heart for a greener planet – from Portugal to Singapore, passing through Spain, the United States, Brazil, Greece, Italy, Poland, Romania, Hungary and the United Kingdom, we had 705 volunteers participating in the various actions that took place on this day, such as beach cleaning, walks and solidarity runs, the participation of which went to the global organization Plant for the Planet and Make-a- Wish Portugal, along with some local organizations, depending on the initiatives promoted. On the other hand, a new global campaign was launched – Go green – challenging teams from several countries, between September 15th and October 15th, to carry out environmental initiatives. In this new campaign, 235 EDP volunteers and 84 EDP Friends were involved, in a total of 903 working hours of volunteering, and around 2.3 tons of waste could be collected. From Brazil to Singapore, passing through Chile, Portugal and Spain, there were several geographies that promoted environmental volunteering actions that marked this period and contributed to a greener planet. Global programs In 2023, an effort to converge and align similar social investment programs developed in different geographies where EDP is present began. The objective is to guarantee an integrated narrative of the programs and incorporate the best practices of each EDP Business Unit. Within the scope of this initiative, the following programs were covered: EDP Energy Solidarity This program was based on the EDP Solidarity program in Spain, Portugal and Brazil. Initially with the sole objective of promoting the quality of life of socially disadvantaged people and the integration of communities at risk of social exclusion, in recent years, this program has specialized, giving greater attention to sustainability, innovation and equal access to energy in the areas where EDP carries out its activity. This new approach gave rise to a new name for the program - EDP Energy Solidarity \- which aims to support projects that contribute to a fair and inclusive energy transition, promoting access to energy (Brazil), sustainable mobility (Portugal and Spain), energy efficiency and the use of renewable energy (Portugal, Spain and Brazil) and support for communities in transition (Spain). Know more about this program in Spain: EDP Energía Solidaria Know more about this program in Portugal: EDP Energy Solidarity Energy Inclusion To address the problem of energy poverty, the EDP group promotes several projects focused on implementing energy efficiency measures and raising awareness about the responsible use of energy that allow reducing the energy bill of identified families and NGOs and changing their habits of consumption. The scope of intervention is quite broad because the solutions can be passive (thermal insulation, windows, doors) or involve the installation of more efficient equipment, household appliances, LED lighting, or even self- consumption solar panels. In addition to the solutions, EDP also promotes energy literacy by training families on habits and behaviours that promote energy savings on a daily basis. In 2023, projects belonging to this program were developed in Portugal, Spain and Brazil. Know more about this program: Energy Inclusion Solidarity Solar Through this program, EDP promotes the installation of self-consumption solar panels in needy communities in Portugal, Spain and Brazil. In addition to guaranteeing access to clean and renewable energy, in cases of communities that often do not have adequate electrical infrastructure and where interventions are also carried out at the level of the Energy Inclusion project, it also results in significant savings on household energy bills, promoting sustainability, social inclusion, improving the quality of life of residents and local development. In Portugal, the Solidarity Solar program started in 2022 in the neighbourhood of Cova da Moura, a community located on the outskirts of Lisbon, which faces challenges related to the lack of basic infrastructure, namely electricity.

Know more about this program: Solidarity Solar Your Energy This EDP educational activity aims to explain to young people the difference between the different types of energy generation technologies. The sessions consist of leading students through the world of renewable energies using children's characters representing solar, hydraulic, wind, geothermal and biomass energy, accompanied by videos and interactive presentations allowing them to learn about their different characteristics in an easy and attractive way. As part of this program, a dedicated website was also developed, where students and teachers can find the content to be used in the sessions. In 2023 this website was available in Portugal and Spain and, in 2024, it is intended to be used in the remaining countries where EDP develops this program. Know more about this program: Your Energy In 2024, the aim is to continue with the convergence work, increasingly promoting the alignment of initiatives that are part of the EDP group's portfolio of social investment programs. 3.4.9.2. Just transition The Just Energy Transition process engages through three pillars: Innovation (deploying solutions for a fast and secure outcome); Access to Energy (Fighting energy poverty and taking energy to all places in the World, as in the A2E project and fund by EDP), and Community Engagement: Leaving no one behind must be a common signature for all transitioning, since the Coal production phase-out, and the overtaking of new territories by Renewable Energy solutions, are dramatically impactful on local economies and cultures. It becomes eventually even more demanding when displacement of population takes place, in order to develop new energy sources. EDP is deeply committed to earn its License to Operate through preventing early engagement with local communities, promoting shared value upon its approach. This commitment is showcased at Sines, where one of the largest coal power plants in Portugal operated with a 1,256 MW capacity, from 1985 until 2021. Sines former coal power plant is already in the process of decommission with plans to become an H2 hub reference in Portugal. Social impact program Futuro Ativo Sines, (featured by the World Economic Forum in its coal to renewables toolkit, specifically addressed the needs of the subcontractor’s workers, as well as the local community at large, with entrepreneurship programs, vocational training in partnership with the employment agency, support for local action NGO’s, a dedicated office for social support, etc. It was designed as a Fair Transition tool for the southern Portuguese region and promoted (from its early academic assessment on the local economy prospectives) the launch of the Observatory for the Just Transition of Alentejo Litoral. The numbers evolved in 2023, showing the success of its implementation: 77% have found new jobs, and are now working; 12% in training and 11% retired or are under health leave. After working for more than two years the support office put together with the Sines Municipality and the National Institute for Skilling and Employment (IEFP) achieved its goals and reached very low levels of demand and as such was closed on Jun 2023 with the following results : 117 registrations were held there, 19 requests for social support and three people received psychological support (all not related to the plant). The reskilling program created reached 24 persons and the entrepreneurship scholarship reached 45 entrepreneurs with 36 business projects that may create 22 jobs and it is still ongoing on sines. 33 social entities received material from the dismantled plant worth more than 330k€; and 11 local ONG received from the Fund created to support the region, EDP Solidária Sines, a total of 141,000€ benefiting more than 3000 people. And in Spain, the program EDP SUMA+, structures the engagement of social and environmental landscapes, supporting local communities in Aboño, Soto de Ribera, Los Barrios and Puente Nuevo, four projects endorse communities into entrepreneurship, school and technical education and further quality building within common facilities, through ENTAMA, Tech Camps, EDP Partners and EDP + CERCA. 

130 Part I Integrated Annual Report 2023 Performance | Sustainability Also in the APAC region, EDP has been implementing the local stakeholder approach new policy, reinforcing the Community engagement strategies. In North Singapore, deploying solar DG on the Pulau Ubin island was a visible incentive into the walking the talk approach, since there was no business interest in the region, but rather on implementing the energy transition as a flagship locally, since Ubin is a deeply respected natural sanctuary... but had a power grid fed by diesel fuel generators, now partially transformed into solar DG: the enhanced microgrid system is powered by 328 kWp of solar energy, equipped with a 1 MWh vanadium flow redox battery energy storage system, creating an electrical ecosystem that powers the island with non-intermittent renewable energy, capable of meeting at least 95% of the key business and residential needs. Today, more than 30 households and businesses enjoy 24/7 non-intermittent renewable energy, thereby reducing the island's reliance on diesel by more than 100,000 litres per annum, avoiding 268,000 kg of CO2 emissions. With the use of solar power, it also stabilizes the electricity pricing for residents, as they are no longer subjected to the price fluctuations of diesel. Also in Vietname the strategy to a just transition is rooted on seeding a solid educational bases to the whole population on operation areas – and this was why EDPR invested on a powerful transformation on the education facilities and tools for populations around operation areas (Xuan Thien Thuan Bac and Xuan Thien Ninh Thuan Solar farms play a crucial role on the transition, aligned with the approved master plan (PDP-7), these projects boast a total capacity of 255MWp.).The back to school operation covered over one thousand households, also endorsing economically fragile families, and further developing local institutional relations with the authorities. This long-term investment on education, deeply knowing the population and transparently engaging, was part of EDPR’s recognition as the first project worth of a Fast Infra Label Assessment. EDP worked closely with the European Union institutions into fasten the policy making, the funds and the acts protecting the energy transition. A just transition can only be achieved with the close involvement of all stakeholders at the European, national, or local levels. To ensure that social impacts are reduced or even avoided in all locations where thermal power plants previously existed, EDP has been committed to adapting these facilities to new technologies, particularly in the creation of Hydrogen and Storage Hubs, especially in Spain (Aboño, Soto de Ribera and Los Barrios) and in Portugal (Sines). To make these technologies a reality, in 2023, EDP has been closely collaborating with several entities to secure European funding. Some successful initiatives have been acknowledged as pioneering, thus empowering local communities with future economic perspectives, as in the Aboño H2 project (remarkable synergies among different funding programs); Los Barrios (IPSEI and Pioneros recognition); Soto de Ribera (Pioneros’ Recognition, Soto 2 now being decomissioned) The Sines project in Portugal has received recognition from the European Commission by being awarded through the competitive Innovation Fund. Pulau Ubin “Since 2013, the Pulau Ubin micro-grid has provided more than 30 of the island's residents and businesses with a more reliable, cleaner and affordable electricity supply, while also being a living lab for innovative, clean energy solutions. Through a research and development grant, the Energy Market Authority (EMA) of Singapore has supported the enhancement of the Pulau Ubin micro-grid with a Solar Green Roof and Energy Storage System. These enhancements could potentially help the micro-grid meet 90% of the daily electricity demand in the main village using solar power, while regulating ambient temperatures and increasing the efficiency of rooftop solar deployments. The test-bedding of these innovations in a micro-grid will provide useful learnings for mainland applications and support Singapore’s journey towards a more sustainable energy future.” Violet Chen, Director (Industry Ecosystem Development), Energy Market Authority of 

131 Part I Integrated Annual Report 2023 Performance | Sustainability This work is being constantly updated, following the new projects in the pipeline by EDP and the new programs launched at national and European levels. Throughout 2023, EDP promoted its constant engagement with European Institutional stakeholders, sector associations and peers in order to promote enabling policies to deliver the just transition projects stated previously. Renewable hydrogen has been one of the key topics of advocacy activities, considering its potential in the transformation and conversion of coal power plants’ areas into green hubs. EDP has co-signed and/or supported, within its membership in associations, a series of letters calling for the definition of a regulatory framework for renewable hydrogen that truly ensures the contribution to the decarbonization of hard to abate sectors and support the execution of projects: • Letter to the European Council and Parliament on the Delegated Act for RFNBOs • Letter on the urgent Adoption of the Renewable Hydrogen Directive • Letter to EU Finance Ministers in order to call for an EU approach to the financing of renewable hydrogen 

132 Part I Integrated Annual Report 2023 Management Report | Innovation Capital The island’s reliance on diesel will also be reduced by nearly 100,000 liters per annum, avoiding 268,000 kg of CO 2 emissions. Differentiating factors: Vanadium flow batteries are ideal for this application of long duration energy storage as they can operate continuously for over 20 years without degradation. It is also a significantly safer technology compared to lithium-ion batteries as they are not flammable, making them ideal for remote applications such as on islands like Pulau Ubin. These unique features of the VRB ESS set it apart from other battery storage systems. The Solar Green Roof helps to regulate the ambient temperature surrounding the solar panels, optimising the efficiency of the panels by up to 4%. The Future: There are potential plans to extend this micro- grid solution to areas outside of Pulau Ubin’s Main Village. This could have a significant impact on the sustainability of other areas in Singapore and contribute to the broader national goal of environmental stewardship and energy security. The learnings from the Pulau Ubin Green Micro-grid project can also be applied across other hard-to-electrify areas in the APAC region. The project marks another landmark for Singapore to be a reference for energy transition in the region –what EDPR seeks to lead– while contributing to EDPR’s solar and storage capacity as well as net zero targets. Link for more information. Pulau Ubin Green Micro-grid Transitioning from diesel reliance to clean, renewable solar energy. Our approach: EDP Renewables APAC, with the support of Singapore’s Energy Market Authority and National Parks Board, has enhanced the micro-grid on Pulau Ubin island in Singapore. The enhanced micro- grid now includes a Solar Green Roof with a 328 kilowatt-peak (kWp) solar photovoltaic system together with a 1 Megawatt-hour (MWh) Vanadium Redox Flow Battery (VRB) Energy Storage System (ESS). More than 30 households and businesses will benefit from this enhanced micro-grid. Country: Singapore 

133 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.9.3. Respect for local and indigenous communities To keep on track with the Paris Agreement of limiting the global average temperature to 1,5˚C, the effort required from the energy transition is immense. The infrastructure required will continue to take over new territories and their population – who may never have seen this type of massive construction and abrupt landscape change before. The paths needed to engage with these communities are urgent and need to bring shared value to the local quality of life. Businesses must endorse the new economy’s people-positive culture, committed to respect human rights as climate change is tackled. Installed clean energy must triple by 2030, but it will only grow consistently if we assure community support: EDP approved its new Local Stakeholder Engagement Policy, with an extensive list of Procedures compulsory throughout the group. The premise is to map and deeply engage with the communities before starting a new project, and to deeply diagnose, through independent external studies, the real impacts business will have on the new energy landscape. It’s the safest path to build shared value, supporting communities before construction begins and earning a social license to operate. A preventive identification of risks and knowledge of the local stakeholders will frankly diminish the chances of deep crisis further ahead. This new approach was developed under the lighthouse project for ESG at the EDP group, called “Community Gate Keeper”. Under this umbrella, all local Stakeholder teams now have a common SharePoint to share best practice and lessons learned. Quarterly meetings are held to improve their Community Rights protection tools. Community Gate Keeper monitors the group’s activity towards local populations and reports regularly to the EBD and the GSB on impact achieved or avoided. Tackling these new community challenges, EDPR has implemented a proactive approach that emphasizes effective communication, transparency, and community engagement. Listening to the concerns of local communities and addressing them in a timely and meaningful manner is a priority. The CRC, “Community Relations Coordinator” figure was created in North America for EDP to be close to any situation needed to address throughout the region. This project, implemented in 2023 and bringing locally respected society figures to work closely with EDPR, has been most welcome locally and has become a strong facilitator for local relations and developments. Still, some flags were shown and are being addressed as follow: • In North America, community opposed the construction of the Rolling Uplands Wind Farm, and a deep dive engaged impact study is ongoing before any further decisions are taken. A previous community concern raised with the Misenheimer Solar Park has been surpassed and is now under the construction phase, strongly aligned with the local authorities. In Wisconsin, two townships required restrictive ordinances on the Marathon Wind Farm, opposed by EDPR. • In Brazil, the Northeast region EDPR won its first project in the state of Paraíba and a preventive social diagnosis was carried out in advance, aiming to plan the social and communication actions to be carried out in these communities. As a result, the departments of Environment, Social and Public Affairs & Community Relations drew up an action plan to be executed through-out 2023, which included initiatives addressing: • education and improvement of school environment, catering for almost 500 students in the municipal educational network • cultural events throughout the year, with theater plays and movies in public spaces • sports events throughout the year designed to promote socio-emotional benefits of sport • development of rural enterprise to inject economic dynamism into socioeconomically deprived regions, through technology involving agroecological production, combating drought, water security and food supply safety • development of a social project to train young people for the job market • creation of a narrative aligned and coordinated with the rest of the industry through the largest industry body, Abeeolica, and • preparation of a differentiated communication plan for the region. A whistleblowing channel is in place and by the end of 2023 no major issues have been reported. Monthly meetings have also been held with communities since May 2023, which have gone off without a hitch. The surroundings of São Manoel Hydroelectric Power Station are historically inhabited by the Kayabi, Munduruku and Apiaká ethnic groups, made up of around 1,400 people living in 19 villages on the banks of the Teles Pires River. Built in June 2014 and operating since May 2018, mitigation measures and environmental compensation are still ongoing for the benefit of these peoples, respecting the specificities/particularities of each indigenous people. 17 programs, approved by FUNAI, aim to improve the quality of life of these communities. The monitoring of these programs is made by a Management Council 

134 Part I Integrated Annual Report 2023 Performance | Sustainability created with representatives from the company, FUNAI and each of the indigenous communities involved. The execution is prioritized around actions linked to subsistence activities. During 2023, regarding infrastructures, the following works were executed and delivered in 2023: • Basic Indigenous Health Unit (UBS-I) Bom Futuro Village, Munduruku people • Basic Indigenous Health Unit (UBS-I) Papagaio Village, Munduruku people • Casa de Farinha (Siqueirinha Village), Kayabi People • Meeting Shed, Community Kitchen and Photovoltaic Energy System (Kururuzinho Vil- lage), Kayabi People • Photovoltaic Energy System (Teles Pires Village), Munduruku People • Meeting Shed and Photovoltaic Energy System (Bom Futuro Village), Munduruku People Another action that continued in 2023 was the maintenance of the granting of higher and technical level scholarships, within the scope of the Program for the Strengthening of Indigenous Organizations, all 39 scholarships were awarded. So far, eight students are trained in the area of health, nine professionals with courses completed in the area of education and already work in the classroom as teachers, three graduated in the area of Law, another three graduated in Business Management and one in the area of forest engineering. The established procedures in place ensured that, throughout 2023, as in previous years, the EDP group was not subject to accusations or suspicions of violations of fundamental human and labour rights. However, occasional occurrences, which were neither structural nor recurrent, were recorded and dealt with, often related to individual behaviours, and translated into individual complaints that were endorsed and solved within the framework of the ethical process and, when justified, gave rise to corrective measures, penalties or reinforcement of procedures. Additionally, the EDP IMPULSA programme was created by EDPR in Brazil with the objective of supporting the professional development and employability of people in the communities where the company operates. Following a social diagnosis performed with the collaboration of the local government, a high unemployment rate was identified among young adults who lacked basic training to find employment in the region. Scholarships for vocational training courses were offer to residents and over 120 students received training on High Voltage Building Electrician, Industrial Sewing Machine Operator, Bricklayer, and Motorcycle Maintenance Mechanic. Keeping engaged with communities But it is not just in operation areas that EDP feels responsible for a healthy society: the work aims on promoting the wellbeing and development of society as a whole, focusing on the people who contribute to the success of the company’s business and how society may benefit from it. During 2023, it is worth highlighting what was achieved in La Guajira (Colombia). With the goal of improving the lives of the most vulnerable people, the donation of 100,000 COP helped 700 families (about 3,150 people) affected by the winter cold wave. This donation mitigated some basic needs through the delivery of non-perishable food kits were delivered in Uriba, Maicao, and Albania. In Greece, one of the company’s various initiatives is the collaboration with the cleaning of Lokron beach, located in the Malesina region near Livadi and Erinia wind farms. By organizing and participating in beach clean-up activities, EDPR has helped preserve the beauty of Lokron beach and protect its ecosystem. 

135 Part I Integrated Annual Report 2023 Management Report | Social capital EDPR considers prior consultation to be a mechanism that assists in listening to the needs and realities of local communities, as well as guaranteeing their right to participation. Differentiator factor: With that in mind, the field teams have sought to think ahead and strengthen their relationship with the communities through educational activities in which they can combine their ancestral knowledge with the opportunities that come with working alongside the private sector. One such example of this are the educational spaces and workshops on environmental issues that have been implemented in La Guarija. What lies ahead: The company will continue to ensure that best practices in prior consultation are carried out to promote the path towards intercultural understanding and to recognize a human and ethnic right. Link for more information. Prior consultations A mechanism that guarantees the listening and free participation of the communities in Colombia. Our approach: Prior consultation is a fundamental right of indigenous peoples and other ethnic groups before deciding on actions that affect the self-determination of peoples, either by legislative and/or administrative measures or the implementation of projects, works or activities within their territories. The parameters for prior consultations were defined by Ruling SU-039/97 and they seek to protect the cultural, social and economic integrity of these communities and guarantee their right to participation. In the Sierra Nevada de Santa Marta, EDPR considered the specific governance system and environmental conservation values of the four peoples in the local communities. They initiated a prior consultation with these communities, which is estimated to last three months. The engagement between EDPR and these communities has been positive, and there are plans for meetings and tours to be held. In La Guajira, Colombia, EDPR conducted environmental education workshops with the ethnic communities in the area of influence of the Beta wind farm. These workshops facilitated outreach with the communities, allowed for the exchange of knowledge, and helped EDPR to better understand how the communities perceive the project, ultimately identifying opportunities for improvement. Country: Colombia 

136 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.10. Human rights 3.4.10.1. Respect and advocate for human rights EDP has in place a Human Right’s Policy based on the international frameworks defined by the United Nations and the International Labour Organization. Within the framework of the United Nations, EDP follows the principles of the "International Bill of Human Rights", as well as the different instruments to protect vulnerable people and groups. In addition, fundamental labour rights are enshrined in eight International Labour Organization conventions, covering namely the freedom of association and the effective recognition of the right to collective bargaining; the elimination of all forms of forced or compulsory labour; the effective abolition of child labour; and the elimination of discrimination in respect of employment and occupation. From a management approach perspective, the following topics are addressed under this Policy: • Non discrimination • Integration and Inclusion • Freedom of association and collective bargains • Abolition of forced labour • Abolition of child labour • Equal pay, remuneration and work environment • Rest and family life conciliation • Health and Safety environment • Environmental protection and impact on the land • Data protection EDP has a common and global approach to ensure the respect of human and labour rights along its value chain, implementing policies, processes and measures to ensure the protection of these rights. The company's main objective is to avoid abuses of human rights both in its own activities and along its supply chain; ensure a safe and healthy environment for its direct and indirect employees, promote a just and ecological transition, and ensure an activity aligned with the needs and expectations of local communities. The purpose of this chapter is to clarify conceps and scope of action and serve as an index to support readers better understand where specific chapters disclosing human rights practices are detailed along this Report. The chapters in which human rights management is addressed are specified below, with the organisation's stakeholder engagement process being considered as a starting point, as it is essential to understand the needs and expectations of EDP’s stakeholders in order to be able to manage the risks related to human rights that may arise along the value chain. 

137 Part I Integrated Annual Report 2023 Performance | Sustainability Governance The previous mentioned approach requires the involvement of several departments within the organization, each of them playing a key role in ensuring that all necessary practices are put in place. At the highest level, human rights governance follows the sustainability governance. The General and Supervisory Board of Directors is the body ultimately responsible for overseeing human and labour rights, through its Corporate Governance and Sustainability Committee, which has the highest responsibility to oversee all Sustainability aspects. At the executive level, the Executive Board of Directors is supported by a sustainability team that coordinates and consolidates and monitors performance and initiatives carried out by all the operational departments involved. Among the teams involved in the process are ethics, compliance, procurement, health and safety, environment and people management. Stakeholder engagement process The protection of human and labour rights starts with an effective stakeholder management. Depending on the stakeholder, a series of processes and means of engagement are established to respond to the particular needs and manage any impact (positive or negative) that the company may have. This engagement is central to risk identification and used to prioritse action. Please refer to stakeholder management for more information on the process and consider the materiality process to better understand the overall identification of material topics. To guarantee compliance with human rights’ internal policy, EDP diferenciantes its approach among direct and indirect stakeholder groups. Direct group includes the ones closely related to the company's value chain, such as: suppliers; employees and contractors; and local and indigenous communities. Indirect stakeholders are those who have an influence on EDP's activity and determine how the company's issues and priorities are addressed. This latest one include: civil society and governments; investors and shareholders; and customers, consumers and offtakers. Risk Analysis and Human rights Materiality The materiality process carried out by the company identifies human and labour rights as one of the material categories for EDP's direct and indirect stakeholders. Please refer to the Materiality chapter of this report for more information. The human and labour rights protection continues with risks assessment. This exercise is carried out by assessing the country risk, the local risk and the specific risk of each activity and equipment, according to the nature of the project, informed by the sector's risk map. Depending on whether we are considering new investments, the creation or modification of infrastructures, contracting suppliers and other counterparties, or operations with customers and employee management, specific risk control and mitigation measures are implemented (additional information can be found in previous Human Rights reports published by EDP in 2021 and 2022). EDP faces indirect risks of failure to respect fundamental labour rights, relating to the extraction and production of the equipment necessary for the value chain of manufacturers of electrical technologies. These risks occur several levels upstream of the direct suppliers and focus on internationally identified regions. Please refer to EDP’s 2022 Human and Labour Rights Report for more information regarding other potential human and labour rights risks that could occur in the value chain. Due diligence process Policies and Codes of Conduct The human rights due diligence process begins with the company's public commitments and codes of conduct, which are the starting point for ensuring the respect of human rights throughout the value chain. These policies and codes apply to a wide range of stakeholders working directly or indirectly for EDP. The commitments are set out in the Human and Labour Rights Policy updated in 2021, aligned with EDP’s Code of Ethics, principles and commitments. Additionally, EDP has a set of specific policies and codes addressing concrete issues under the human and labour rights framework, listed below. The Human and Labour Rights Policy covers the EDP group worldwide. It identifies the references, standards and international conventions to which it is subject, establishes the strategic principles, specifies the principles for action, assigns responsibilities, determines obligations and management bodies. The Policy details operational commitments, its workings, complaint and communication channels, reporting and training obligations and 

138 Part I Integrated Annual Report 2023 Performance | Sustainability extends obligations to suppliers. In particular, the Policy sets out Due Diligence procedures, implementing the Ruggie and OECD methodology, and anticipating the EU Due Diligence directive. Tools and Management Systems To adequately implement the Human and Labour Rights Policy, EDP has a set of tools in place. Any stakeholder group can use the Speak Up Channel that the company makes publicly available. Issues are handled anonymously to ensure that there is no conflict with the whistleblower. In addition, the company has an Integrity Due Diligence (IDD) process to identify integrity-related disputes or potential human rights abuses on business partners. Additional information on the Speak Up Channel outputs, please consult Operational and ESG indicators and the Ethics Ombudsperson Report 2023. To manage potential risks in the supply chain, the company has a Sustainable Procurement Protocol that serves as a guide for the integration of sustainability aspects in purchasing and to define the criticality of suppliers. This protocol is framed by the Sustainable Procurement Policy and complemented by the Supplier Code of Conduct. Additionally, is complemented by specific actions such as screening of suppliers in terms of human rights, mechanisms to know the traceability of components or other tools that make up the EDP due diligence process in the supply chain. More information on human rights management in the supply chain can be found in Supply Chain. Regarding health and safety management of employees and contractors in operations, EDP’s Corporate Safety Management System (CSMS), in alignment with ISO 45:001, is certified by LRQA, and additional information is detailed both in Health and safety and EDP’s Health and Safety report. The CSMS frames the guiding procedures for companies at local level, which may follow directly CSMS or have their own operational SMS system. Regarding to human capital, EDP has internal policies and procedures that seek to promote equality and non-discrimination, the recruitment and retention of talent and the reconciliation of work and personal life. In addition, for each country in which the company operates, it has systems in place to ensure compliance with regulations regarding collective bargaining agreements and workers' rights. Please refer to Own Workforce for more information on human capital management. Furthermore, EDP approved its new Local Stakeholder Engagement Policy, with an extensive list of Procedures compulsory throughout the group. The main goal is to assure the full Human Rights legislations respect, under the terms set out in the EDP group's current internal regulations. For aditional in information on this subject, please refer to Affected Communities. Championing human rights programme Framed by its Social Investment Policy, EDP prioritizes social inclusion programs, particularly aimed at vulnerable communities, for skill development and energy inclusion. This is in line with the B4SI methodology, and the global priorities of the United Nations as expressed in the Sustainable Development Goals. The focus is on combating energy poverty and implementing energy access programs for populations not connected to electricity grids. For more information on these programs please refer to Affected Communities. Moving Forward 2024 will continue to be a demanding year, with an action plan mostly focused on the following issues: • Supply chain traceability and human rights management practices improvements, due to the challenge of getting into the tier+1 • Local communities, with the roll-out program of the new Local engagement Policy approved in 2023 • Local employment, by implementing the just transition process for phasing out coal with the development of "green hubs". This local reinvestment, mainly in Spain, includes hydrogen pilot projects, storage projects and other solutions to make the system more flexible • Health and Safety with the PlayitSafe Program development.

140 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.11. Energy consumers and end-users EDP has been expanding its commercial activities and currently has a presence in several European countries and Brazil. With a portfolio increasingly aligned with the energy transition, EDP offers its residential and business customers a range of products and services, spanning from energy supply to solutions in energy efficiency, electric mobility, and decentralized solar energy. In Iberia, the regulatory framework defines the separation of distribution (regulated market), supply (liberalised and regulated market) and supply in the regulated market. While, in Portugal, EDP operates in the three activities through independent companies, in Spain it is present in distribution (regulated market) and supply (liberalised market). In Brazil, in the states of São Paulo and Espírito Santo, EDP operates in the regulated market, in distribution and supply, as well as in supply in the liberalized market. In the current market context, there are several events and trends that put pressure on service quality and challenge the commercial relationship with customers, of which we highlight the following: • the volatility in the energy markets that forces adjustments in price and contractual conditions and the search for solutions that favour price stability and predictability • the priority to decarbonise and adapt to climate change, through continuous technological, digital and legislative innovation • new regulatory dynamics and customer behaviours • the growing importance of energy services compared to the traditional business of selling energy As a result, transformation dynamics in the market context are changing the classic segmentation of customers, widening their diversity and expanding business opportunities and challenges. In this area, we continue to see a growing focus on trends towards the energy rating of buildings, the acceleration of electric mobility, self-consumption and energy communities, and the increase in the divide between customers with the capacity to invest in energy efficiency and customers in the state of energy poverty. The EDP group maintained its commitment to accelerating investment in commercial innovation by diversifying its portfolio of services and markets to ensure a highly satisfying customer experience through its commercial services, and excellence in the quality of the commercial relationship. Commitments that are part of the EDP’s values and culture and translated into quantitative strategic objectives. 3.4.11.1. Promoting sustainable consumption Aligned with the group’s ambition to be a global leader in the energy transition, EDP has been expanding its commercial portfolio to offer products and services that empower consumers to contribute to a more sustainable planet. Efficient equipment To achieve carbon neutrality, it is critical not only to electrify consumption, but also to consume energy in a more conscious manner. In 2023, EDP added a particularly innovative product to its portfolio – a solar water heater, in partnership with Mixergy, that enables savings of up to 60% on the water heating bill. Resorting to artificial intelligence, this equipment adapts to the consumption patterns of the household, heating only the necessary water when energy is more affordable, and doing so five times faster. Additionally, the equipment also harnesses surplus solar energy to heat water for free and use later. Decentralized solar energy This clean and virtually inexhaustible source of energy allows customers to be active participants in the energy transition while reducing exposure to electricity price fluctuations and, therefore, accessing significant savings on the energy bill. EDP offers solutions that allow customers to maximize the investment and benefits of the solar installation, including a consumption monitoring system and the option to install a storage battery so that customers can not only consume their solar energy during the day but also store it for later use. For the business sector, EDP develops customized offers to accommodate the unique needs of each business, with a focus on the as-a-service model, in which EDP takes on the entire investment and is responsible for the installation, operation, and maintenance of the solar plant. 2023 was also another year of growth for Solar Neighbourhoods, renewable energy communities that are democratizing access to solar energy. In these neighbourhoods, producers make their space available for the installation of solar panels, and the energy produced is shared among the community's neighbours. 

141 Part I Integrated Annual Report 2023 Performance | Sustainability Electric mobility EDP is present throughout the entire journey of electric vehicle users, from research to the use of charging solutions at home and in public spaces. In addition to information initiatives and integrated offerings for private charging, EDP has significantly expanded its public charging network, surpassing the 4,500 contracted charging points in the Iberian Peninsula in 2023. EDP is focused on developing charging solutions for all use cases and in 2023 launched a new product for corporate fleets, which currently represent about 80% of the electric vehicles sold in Portugal. The EDP Charge Fleet card aims to simplify the adoption of electric mobility by allowing a company to allocate a direct credit to each employee, which can be used for charging on the street, at work, and at home. In a pioneering solution for the Portuguese market, an EV driver has access to a single tool that allows them to charge the electric vehicle according to their needs. This solution is integrated into the ecosystem of solutions for companies, which also includes the installation of chargers for private spaces, a digital portal where fleet managers can manage chargers, analyse consumption, allocate credits, among other features, as well as the EDP Charge App, where each employee has access to innovative features such as home reimbursement and integrated payment management. 3.4.11.2. Customer satisfaction The EDP group has made the commitment to maintain a customer satisfaction level of over 85%. This objective is monitored through customer satisfaction in their interactions with the company, the number of complaints, and through satisfaction questionnaires carried out periodically. In Portugal, in the liberalised market, a satisfaction level of 92% was achieved, an increase on the previous year. The NPS (Net Promoter Score) of the liberalised market, which measures the degree of customer recommendation in relation to the company, was 28% in B2C segment and 27% in B2B. In the regulated market, satisfaction levels reached 88%. In Brazil, the main indicator used to measure customer satisfaction is the Quality Satisfaction Index (ISQP), obtained through the ABRADEE Residential Survey. In 2023, there has been an improvement in the ranking (EDP São Paulo 76% and EDP Espírito Santo 75%). In Spain, the B2B segment recorded an average satisfaction rate of 7.6 (on a scale of zero to ten). 3.4.11.3. Complaint and claim management The EDP group continuously invests in the development of channels and means of handling complaints and grievances, as well as improving customer experience. In addition to facilitating conventional means of service, alternative solutions to those provided by law are made available, such as the Customer Ombudsman, the Ethics Ombudsman (see Ethics) and participation in citizenship initiatives, such as the Complaints Portal. In Portugal, EDP has a Customer Ombudsman, an independent body whose role is to assess customer complaints in cases where they are not satisfied with the responses obtained from the standard system.

142 Part I Integrated Annual Report 2023 Performance | Sustainability In Portugal, in the liberalised market, despite the continuation of a context of high volatility in the market, the energy supply segment recorded a significant reduction in the volume of complaints (-7p.p. compared to 2022), reaching the lowest value ever recorded. This result is mainly due to the greater robustness of business cycle processes and a less severe winter that resulted in fewer incidences of power failure and/or losses. Regarding solar energy, there was a reduction in the volume of claims, despite a significant increase in installations. This was due to the continuous improvement of sales, installation and after-sales procedures and evolutions in the performance of the smart meter replacement process and settlement activation. As for electro mobility, due to the context of strong growth of this activity, there was a natural increase in the volume of complaints, although not significant when compared with the installed number of recharging stations and CEME cards. In B2B energy in Spain, as in Portugal, the year was marked by the continuation of a very volatile context in the energy market, but the stabilization of the regulatory context compared to the changes that were implemented during the year of 2022, led to a sharp drop in the number of complaints.

Energy prices In the Iberian Peninsula, energy supply is free, and consumers can contract it with any supply company. In Portugal, and according to ERSE, in September 2023, the liberalized market represented around 86% of total customers and approximately 94% of consumption, and the regulated market tariff is expected to be abolished at the end of 2025. Until then, liberalized market Normal Low Voltage electricity customers have the right to access a scheme equivalent to regulated tariffs and may return to the regulated market if their supplier does not provide this equivalent scheme. The average reference price tariffs for end user in Portugal, in 2023, was mostly composed of energy and supply costs (113%), as a result of the high level of electricity prices in wholesale markets, with the costs of energy policy not being a cost but a revenue of ≈-29% of total value and use of networks representing ≈17% of the total value. In Spain, on September 2022, the liberalized market accounted for 70.8% of total customers, corresponding to 98.4% in the SME segment, 98.6% in industrial segments and 69.9% of customers in the domestic segment. Domestic prices in Spain, from June 2023 onwards, included a component of energy policy costs of around 11% of the final tariff, while the energy and network use components represented, respectively, 60% and 29% of the total. In Brazil, in September 2023, the liberalized market represented more than 37% of the country's total electricity consumption, with a total of 36,329 customers. Since January 2021, consumers with contracted power equal to or greater than 1,500 kW can buy energy from any source as liberalized consumers, with this threshold being reduced to 1,000 kW in January 2022 and to 500 kW in January 2023, under the terms of the Ordinance 465/2019, from the Ministry of Mines and Energy (MME). In September 2022, MME Ordinance 50/2022 was published, which allows high voltage consumers to purchase electricity from any supplier from January 2024. In the same month, a Public Consultation was opened with a proposal for an Ordinance containing the schedule for opening the low voltage market starting from 2026, with predicted total opening by 2028, including residential and rural customers. With regard to the breakdown of the price of electricity, energy and supply costs constitute about 50% of the costs invoiced to the customer, with the costs of using the networks (transmission and distribution) and energy policy corresponding to around 39% and 11%, respectively.

Country: Portugal 

144 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.11.5. Quality of service Improving the quality of the technical service provided to customers is one of E-REDES' main goals as a distribution network operator. E-REDES maintains a process for rigorously monitoring the quality of the technical service, allowing for the adoption of mitigating measures whenever justified. At the same time, complementary checks and analyses are carried out at customer delivery points, in accordance with regulatory provisions. These procedures are designed to help optimise the maintenance and operation of the distribution network, with a focus on improving the quality of service provided. In 2023, the quality of service, particularly with regard to continuity of service and the quality of electricity, remained high as a result of the commitment of the technical teams, in a joint effort between E-REDES and the service providers, and of management measures, new investments and cooperation and dialogue with stakeholders. In Portugal, the good performance of the distribution network has been helped by specific investments and maintenance plans for network assets, as well as modernisation and automation projects for the HV, MV and LV networks carried out over the last decade. The main continuity of service indicators have stabilised in recent years, confirming a general trend that reflects the good performance of E-REDES in improving the quality of technical service in electricity distribution. In 2023, the distribution network was subjected to several extraordinary weather events in various parts of mainland Portugal, including the storm at the beginning of the year on 1 January, the Babet depression on 17 October, the Aline depression on 19 October, the Bernard depression on 22 October, the Ciarán depression between 1 and 2 November and the Domingos depression on 4 November, which had a major impact on electricity infrastructure. E-REDES developed an effective response to the events mentioned above, in order to minimise their impact on the quality of service for customers in the affected areas, having alerted its entire operational structure with the activation of the POAC-RD (Distribution Network Operational Crisis Action Plan), resulting in the reinforcement of E-REDES teams, the contact centre (handling fault reports) and its external service providers and the reinforcement of the allocation of vehicles, generators and other specialised equipment. E-REDES España, for the third consecutive year, stands out as a leading company in terms of security and quality of supply, as a result of the investment made above all in digitalising the network so that it becomes totally intelligent, and in operational efficiency. E-REDES España also obtained AENOR certification in Business Continuity according to the ISO 22301 standard. This is a very important milestone, as it is the first company in the electricity sector in Spain to obtain the ENAC 1 seal on its certificate, as it focuses business continuity on distribution processes (operation, maintenance, and management of communications with its customers in the event of a breakdown). ENAC accompanied the certification audit with the aim of extending AENOR's accreditation to the "25 - Electricity generation and distribution" sector, which also ended up materialising. This success was possible thanks to the strong involvement and support of the Board of Directors and the efforts of the team made up of employees from the Networks area and the DCNySF structure area. In Brazil in 2023, the indicators of distributors EDP São Paulo and EDP Espírito Santo remained below the regulatory limits established by ANEEL, mainly due to improvement actions and preventive maintenance. Distributors count on specific projects to improve quality indexes and are focused on remedying recurrent cuts, the improvement of internal processes and the acquisition of new technologies. In the last year, the indicators of Equivalent Duration of Interruption per Consumer Unit (DEC) and Equivalent Frequency of interruption per Consumer Unit (FEC) recorded in both São Paulo and Espírito Santo was consistently better than the limits defined by the regulator and lower than that observed in 2022. 3.4.11.6. Safety of products and services The safety of products and services sold by EDP represents a fundamental aspect for the sustainability of the business. Risk prevention and control of all activities and equipment is an essential organisational requirement, committed to at the highest level and adhered to by the entire group. Within the scope of energy services in EDP's portfolio, there is a set of promoted practices that foster safety for products and services, namely: • promotion of online simulators that allow solutions to be customised and sized according to each client's needs. In these offers, prior visits are made to adjust the solution and ensure that all additional interventions are considered • steps are taken to ensure that the legal compliance of all services and products is met in accordance with the regulations in force • training and supervision of all installation teams as well as the inclusion of instructions for use and safety rules made available to all customers 

145 Part I Integrated Annual Report 2023 Performance | Sustainability • specific studies for safety analyses of the structure of buildings and of accessory equipment, enabling safety risks to be mitigated or even eliminated, for continuous improvement • regular inspection of assets, according to their function, type and regulation, to ensure their safe operation during their life cycle. 3.4.11.7. Social inclusion of consumers and end-users Vulnerable customers Quality of life and well-being are directly dependent on access to energy and, in particular, to high quality electrical energy at affordable prices. In an increasingly technological and digital society, ensuring that everyone can enjoy this essential asset is a challenge that the EDP group places at the centre of its business strategy, for which it has established quantitative objectives (more details at www.edp.com) and a commitment to contribute to the targets of the United Nations sustainable development goals (SDG 7). EDP’s approach to customer energy vulnerability is based on three pillars: Commercial Commitments EDP scrupulously applies the service guarantees specified by regulation and which aim to protect priority customers from interruptions in the supply of energy. Priority customers are informed individually about supply interruptions that are subject to prior notice, with the minimum adequate prior notice, and have priority in the restoration of service in the event of breakdowns. Priority clients are health services, security forces, firefighters, civil protection, maritime and air safety, and penitentiary facilities. Similarly, for customers with special needs, with limited vision, hearing or oral communication or olfactory deficit, EDP adapts its information and communication systems and guarantees the same levels of quality of service and rights available to other customers. EDP also provides the “Safe Invoice” service, which covers situations of involuntary unemployment, temporary incapacity for work or total and permanent disability. Energy Poverty Energy poverty translates into the financial inability to maintain thermal comfort conditions within homes - temperatures between 18˚ and 21˚C in winter, and 19˚ and 23˚C in summer \- according to the World Health Organization. This can lead to chronic illnesses and other respiratory and cardiovascular complications or even death. The structural causes of energy poverty are poor energy performance of the housing stock and the inability of unemployed and poor families to invest in improving the energy efficiency of their homes. The social impacts of energy poverty are also well-known: deepening structural poverty and social exclusion, with significant impacts on public health. The International Energy Agency estimates that around two billion people around the world suffer from energy poverty and data from the EU Energy Poverty Observatory indicates that the estimated number of energy poor citizens in the European Union ranges between 50 and 125 million of people. EDP argues that support for energy poor customers should be directed at solving the structural problem, fundamentally through the implementation of energy efficiency measures and the adoption of preventive measures to avoid power being cut off in response to non-payment. In line with the European Commission's guidelines, the group also advocates that this type of measure should be financed, preferably by the State, as an obligation of the Social State, or alternatively supported by other consumers as a national solidarity measure. In Portugal, since 2010, legislation has provided for the application of a social tariff for electricity and natural gas, which translates into a discount granted to economically vulnerable customers on the access tariff. The process to access the social tariff was facilitated in 2016, with the expansion of eligibility criteria and its automatic allocation. Financing of the social tariff is ensured, in the case of natural gas, by the transmission network operator, distribution network operators and natural gas suppliers. Regarding electricity, the financing of the social tariff was borne by electricity generators not covered by guaranteed remuneration schemes. However, Decree Law 104/2023, of November 17th, 

146 Part I Integrated Annual Report 2023 Performance | Sustainability expanded the number of financing entities, now covering not only generators, but also electricity suppliers and consumers who buy directly on the wholesale market, without suppliers’ intermediation. In the process of defining the tariffs for 2023, the Energy Services Regulatory Authority estimated a number of beneficiaries of the social electricity tariff in Portugal of around 853 thousand customers, with a discount equivalent to 33.8% of the gross price of the transitory regulated market tariffs, corresponding to €129 million. In turn, it estimated around 51 thousand beneficiaries of the natural gas social tariff in mainland Portugal, with a discount equivalent to 31.2% of the final customers invoice, corresponding to a value of 2.4 million euros. In December 2023, the number of beneficiaries of the social tariff in EDP's customer portfolio amounted to approximately 500 thousand customers for electricity and 19 thousand for gas. The amount supported by EDP, in 2023, in relation to the social electricity and gas tariff was 73 million euros and 2 thousand euros, respectively. In Spain, the social tariff has been implemented since 2009, covering, however, only electricity customers. The mechanism currently in force distinguishes three categories of social tariff beneficiaries, depending on their income level: vulnerable customers, with a 25% discount, severely vulnerable customers, with a 40% discount, and customers at risk of exclusion, with a 100% discount. However, as a result of the publication of Decree-Law 18/2022, of 18 October, vulnerable customers and severely vulnerable customers saw their discounts increased to 65% and 80%, respectively, during 2023. The discounts in question apply to the fixed term and to a maximum energy consumption. The social tariff is not granted automatically and must be requested and renewed periodically by the customer, if they meet the eligibility conditions, in particular, income-related criteria. Following the sale of the B2C commercial business to Total in December 2020, there are no social tariff beneficiaries in the customer portfolio of EDP's suppliers in Spain. From the beginning of 2022, the financing of the social tariff discount is assumed by all agents of the electricity sector value chain as a proportion of their turnover, following the decision of the Spanish Supreme Court, which considered the previous model discriminatory because it only applied to electricity suppliers. The sum financed by the EDP group, in 2023, amounts to €16.2 million. In Brazil, the Social Tariff was implemented in 2002 and consists of a benefit created by the Federal Government applicable to low-income families. This is a discount on the tariff applicable to the residential class of the electricity distributors, which can vary between 10%, 40% and 65%, according to the consumption of each residence, up to a maximum of 220 kWh/month. Indigenous and quilombola families who meet the specified requirements benefit, in turn, from a 100% discount up to a consumption limit of 50 kWh/month. In December 2023, EDP's two energy distribution companies had approximately 625 thousand customers in the social tariff. ANEEL provides monthly databases with the information necessary for distributors to cross-check the information, so that if a customer is identified as falling within the social tariff criteria, the benefit will be granted automatically. However, the EDP group’s contribution to protecting vulnerable customers is not limited to the promotion of the social tariff and compliance with legal obligations. Voluntarily, through its Social Investment Policy, EDP also develops programmes to combat energy poverty. To address this problem, EDP develops and supports projects in several countries focusing on the implementation of energy efficiency measures. The solutions adopted can be passive (thermal insulation, windows, doors) or involve the installation of more efficient equipment (household appliances, LED lighting) or even self-consumption solar panels. EDP also promotes energy literacy through training on behaviours that promote energy savings in everyday life. These projects allow reducing the energy bills of families and NGOs who have difficulty maintaining thermal comfort in their homes and modifying their consumption habits, contributing to the improvement of their living conditions. The theme of social investment projects developed and supported by EDP to mitigate energy poverty and promote access to energy is addressed in greater detail in the Social Investment Report of the EDP group. Access to Energy This third axis is aimed at promoting access to energy for populations without connection to electricity networks, either through investments in companies with this theme in mind, such as SolarWorks in Mozambique and Rensource in Nigeria, or through the provision of an annual financing fund for sustainable clean energy projects in the areas of education, health, water and agriculture, business and community in countries with low electrification rates. 

147 Part I Integrated Annual Report 2023 Management Report | Strategy Strong track record in 17 markets and a commitment to invest €2.5 billion by 2026 to install an additional 4 GWp in solar projects. Differentiator factor: EDP's partnership with Klepierre showcases the integration of sustainable energy solutions in commercial spaces, contributing to significant energy savings and environmental benefits. EDP's global presence and expertise in solar DG, combined with Klepierre's commitment to sustainability, create a powerful synergy that drives positive impact. What lies ahead: Solar DG segment is rapidly growing will be key to EDP as it is expected to represent close to 50% of all new market solar additions globally in the coming years. Link for more information. EDP's Solar DG Strategy and Klepierre Partnership Promoting Solar DG solutions through corporate Partnerships. Our approach: The company has installed 1.6 GWp of solar DG capacity worldwide, with a focus on residential and business clients. EDP's strong track record and dedicated teams have deployed 127 thousand installations across Europe, Asia Pacific, North America, and Brazil. The company is set to expand its solar DG presence significantly in Europe, the US, APAC, and Brazil, with key corporate partnerships driving growth. One of the examples is the partnership with Klepierre with an investment €2 million to install photovoltaic panels in three of its shopping centers in Madrid: La Gavia, Plenilunio, and Príncipe Pío. This initiative is a significant step in Klepierre's Act For Good® strategy, demonstrating its commitment to sustainability and environmental responsibility.

148 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.12. Business conduct 3.4.12.1. Ethics Ethics Office (ETH) and Ethics Ombudsperson activity in 2023 The activity of the Ethics Office (ETH) in 2023 continued to be based on the design, management, and implementation of Ethics Programs, as it has been since 2019. The ongoing program, "Making Ethics Real," aims to reinforce the perspective of the importance of practicing an "ethics of substance" in addition to the already established structural framework. The main objectives of the program include integrating ethics into the company's daily operations and aligning the corporate ethics policy across the entire EDP group. Specific initiatives in 2023 included stabilizing the whistleblowing management model, which now applies to EDP SA, EDP Renewables, and EDP Spain; launching the 2023 Ethical Environment Questionnaire; and initiating a project to create a methodology for identifying and evaluating ethical risks. Continuing from previous years, ethics training and communication were key activities in 2023, with ongoing training sessions from 2022 and a new initiative to reinforce the Speak Up culture. Notably, in-person training sessions were held for approximately 420 middle managers under the title "Approaching Ethics" and "Lead Now" sessions were conducted for 50 new managers. Online training on "Ethical Risks in Business," initiated in 2021, reached 64 mid-level managers in the Generation area, with an overall session completion rate of 77%. To ensure the dissemination of ethical culture, various internal channels published content throughout the year emphasizing the importance of ethics at EDP. This included a global celebration of Ethics Day in October and monthly publication of short videos related to the various topics of the Code of Ethics, known as "The Energy of Ethics." In 2023, EDP maintained specialized partnerships that have complemented their work for years, including collaboration with AESE through the existing Ethics Chair, which has supported executive training for over ten years, and with Católica Porto Business School for another benchmarking study aimed at obtaining information on how companies are addressing and emphasizing key ethics management topics. Efforts to reinforce employees' trust in the whistleblowing process, following a clear recommendation from the 2021 Ethics Survey, continued through various training and communication initiatives, resulting in a significant overall increase in the 2023 survey results. The management of potentially ethical contacts, the responsibility of the Ethics Ombudsperson, continued in 2023 within the new whistleblowing management model shared with the Compliance & Internal Controls Global Unit regarding legislative and/or integrity-related issues. Contacts deemed potentially ethical after investigation are reviewed by the Ethics Commission, which issues appropriate opinions and informs the parties involved. The Ethics Ombudsperson, with the support of the Ethics Office, also supported the activities of the Ethics Committees of EDP SA and EDP Renewables and participated in the meetings of the EDP Brazil Ethics Committee. Specifically in 2023, the Ethics Ombudsperson prepared quarterly status reports on the 2023 Annual Ethics Plan, as well as Management of Whistleblowing Scorecards throughout the year. In 2023, the biannual Ethics survey was administered to the entire EDP population, recording a response rate of 41%, which was 4 percentage points higher than the previous survey and revealed slightly improved overall results. However, it notably showed a significant increase of 13 percentage points in better understanding the whistleblowing. 3.4.12.2. Compliance The EDP group is committed to carrying out its activity in strict compliance with the legislation and regulations, as well as to act in a responsible and oriented way by the highest standards of ethics and integrity, maintaining the idea of establishing Compliance as a strategic part of the company’s corporate culture. This commitment applies to all EDP R entities and to their administrators, employees and contractors who act on their behalf. In this sense, EDP assumes a zero tolerance Compliance policy regarding any non- compliance with the applicable legal and regulatory requirements, especially regarding bribery, corruption or money laundering. To put this commitment into practice, EDP has implemented a Compliance Management System Implemented, under the coordination of the Compliance & Internal Control Global Unit (C&IC), which is aligned with the best international practices, namely with the ISO Standard 37301:2021 - Compliance Management Systems - and with the COSO 

149 Part I Integrated Annual Report 2023 Performance | Sustainability (Committee of Sponsoring Organizations of the Treadway Commission) reference of risk management, internal control and fraud prevention (Fraud Risk Management). The Compliance Management System is essentially based on nine components, which can be framed in three levels of action (as illustrated). Compliance Management System This System is developed at the group level, allowing the harmonization of Compliance management guidelines and methodologies throughout the organization and to different regulatory scopes, covering all activities, businesses, and geographies. Whenever necessary corporate guidelines are specified by business units in order to meet their respective particularities. Through the work developed over the years, EDP currently has different mechanisms, such as a specific governance model, specific policies and procedures, periodic training/awareness initiatives and monitoring and reporting instruments that enable the identification of situations to consider from continuous improvement perspective, responding to internal and external challenges. The EDP group also provides several whistleblowing channels, some global and others specific to certain matters or with a specific scope by company, country or subgroup, whose management is ensured by independent and impartial areas. The Compliance Management System integrates specific programs (SCPs) depending on the risks affecting the group namely: (1) Integrity/Anti-corruption; (2) Prevention of Money Laundering; (3) Personal Data Protection; (4) Prevention of Criminal Risks; (5) Internal Control System for Financial Reporting; (6) Competition; (7) Separation of Activities; (8) Environment; (9) Health and Safety. The Compliance Management System, as well as the respective SCPs, are continuously monitored by the C&IC and periodically subject to internal audits, in accordance with the annual activity plan of the Internal Audit Department or subcontracted to third-parties, and external audits, which may result in the identification of opportunities for improvement, considered for the purpose of improving the Compliance management. Also, from a continuous improvement perspective, a Compliance Survey is conducted every 2 years for all group employees, from all Business Units and geographies, with the aim of assessing their perception and positioning regarding Compliance matters, including their knowledge about the application of the existing Compliance mechanisms in the group. The last Compliance Survey was conducted in 2022, resulting in the development of an action plan that provided for the reinforcement of awareness and training actions. Also aiming at the improvement of the group's Compliance Management System, an annual self-assessment survey is carried out with all Compliance function employees and an evaluation survey by their main interlocutors. 

150 Part I Integrated Annual Report 2023 Performance | Sustainability Integrity, anti-bribery and corruption This Specific Compliance Program has as its central axis the Integrity Policy, which defines the commitments, general principles of action, and duties of the entities of the group, its employees, contractors, and business partners, regarding the prevention of illicit acts. This Policy complements the set of existing norms and compliance mechanisms at both the corporate level (including the Supplier Code of Conduct, the Code of Conduct for Senior Management and Senior Financial Officers, the Related Party Transactions Policy, and the Social Investment Policy, in addition to the group's own Code of Ethics and the available whistleblowing channels), and in the group companies, particularly the prevention and control models of criminal liability previously implemented by EDP España and EDP Renováveis and the Compliance program for the prevention of corruption at EDP Energias do Brasil (which include a significant set of specific Compliance policies and procedures). The group’s Integrity Policy is approved by the Executive Board of Directors, periodically reviewed (last review conducted in 2023), made available to all employees - being a mandatory reading document, with registration of acknowledgement - and is available on the EDP website. This Policy reinforces the zero-tolerance policy regarding corruption or bribery practices, clarifies the prohibition of facilitation payments, and details the principles related to the prevention of conflicts of interest, donations and sponsorships, contributions to political parties, prevention of money laundering and combating the financing of terrorism, as well as guidelines regarding the performance of integrity due diligence of third parties, the relationship with politically exposed persons (PEPs), the acceptance and allocation of offers and invitations to events, and the monitoring of international sanctions. As to whistleblowing, the Integrity Policy reinforces the principle of non-retaliation, listing the different available channels at the internal and external levels, and addresses the process of investigating potential non-compliance situations and identifying and implementing any corrective actions. 3 For calculating this indicator, in 2023, EDP considers the number of third parties analyzed, regardless of the number of times each of them has been subject to analysis. 4 Portugal and Spain data are presented jointly because the operationalization of respective DDIs is centralized. In the operationalization of this SCP in 2023, the following stands out: • The analysis of 5,181 third parties (2022: 6,317), as part of the Integrity Due Diligence (IDD) procedure. 3 4 Integrity due diligence (# of analyzed transactions) The principles and guidelines set out in the Integrity Policy are embodied in specific internal procedures: • the Third-Party Integrity Due Diligence Procedure, namely suppliers, business partners/counterparties, beneficiaries of sponsorship/ donations, employee applicants and other third parties, evaluating the various integrity risks (if necessary, using specialized external consultants), foresees the analysis of possible existing legal proceedings, adverse news, involvement with PEPs, inclusion in sanctions lists, situations of conflict of interest, etc. The analysis carried out results in the assignment of a rating and the issuance of an opinion that includes specific recommendations regarding the approval of the transaction, the adequacy of its contractual conditions, and the monitoring of the contract's execution • the Procedure for relations with PEPs provides for specific rules of action, foreseeing the need to record and communicate certain types of interaction • the Procedure for offers and invitations to events defines rules of action and thresholds for its award and acceptance, as well as review and approval mechanisms • the procedure for the attribution of donations and sponsorships, requires an integrity due diligence of the respective beneficiaries as well as the monitoring of the actual application of the support granted • the conflict-of-interests management procedure establishes rules that guarantee impartiality and transparency in decision-making and to prevent misconduct or inappropriate behaviour • the Complaint Management Procedure defines the principles of action and rules to be followed in the management of complaints received and in the investigation process, involving five phases: preliminary analysis, documentary investigation, interviews, investigation, and the release of a final report. 2,486 1,871 824 Iberia Brazil EDP Renováveis 

151 Part I Integrated Annual Report 2023 Performance | Sustainability • The conclusion of the analysis of 54 cases (2022: 14) related to corruption and bribery - 7 carried over from 2022 and 69 new ones received in 2023 - reported through the different whistleblowing channels made available by the EDP group. Of these, two were considered substantiated, being related to the improper performance of service providers, with whom the contractual relationship was consequently terminated. • The development of training and awareness-raising actions to ensure the strengthening of the compliance and integrity culture, complemented by specific initiatives developed locally according to identified needs, namely: • global training on the Speak Up whistleblowing channels and on the Complaints Management Procedure • monthly global publication of the Compliance Golden Rules, raising awareness of the main principles of different compliance areas, including specific topics related with the Integrity procedures • communication campaigns to disseminate integrity topics as the celebration of the Compliance Officer Day, the Compliance Day and Anti-Corruption Day. In this context, a total of 15,300 participations (2022: 25,637) were recorded in the various sessions made available, corresponding to a total of 5,770 training hours (2022: 7,445 hours). In terms of continuous improvement, the following initiatives stand out throughout 2023: • development and publication of the Corruption Risks Prevention Plan (covering all EDP companies in Portugal subject to this legal regime) under the terms of the General • Framework for the Prevention of Corruption • review and update of internal regulations on Integrity, considering changes in context and continuous adherence to best practices • automation of some of the existing control mechanisms • strengthening the monitoring of the application of the implemented procedures. The corruption risk assessment carried out by the group covers all its operations, being the EDP Integrity Specific Compliance Program certified in accordance with the requirements of ISO 37001 Standard - Anti-Corruption Management Systems, at EDP Energias de Portugal S.A., EDP España, EDP Renováveis and EDP Energias do Brasil. Prevention of money laundering The structuring of the Specific Compliance Program for the Prevention of Money Laundering and Combating Terrorism Financing is based on the specific internal regulations implemented by each of the obliged entities as well as on a transversal procedure regarding the reporting of suspicious transactions. Additionally, and in accordance with legal requirements, the obliged entities have designated a Responsible for Normative Compliance, whose activity is articulated with the governance model defined within the scope of this program and provide a specific channel for the reporting of complaints in this area. In this context, in 2023, no complaints were received nor were any suspicious operations identified at the group level. Throughout the year, compliance with the applicable legal requirements was ensured, with emphasis on compliance with counterparty identification and diligence duties regarding counterparties with whom EDP obliged entities establish business relationships and/or occasional transactions. Personal data protection Th strict respect for privacy and protection of all its stakeholders is assumed by EDP as a commitment to be followed in its activity, throughout the value chain. In this context, the Specific Personal Data Protection Program is one of the main global programs of EDP's Compliance Management System. This commitment is reflected in the group's Data Protection Policy, approved by the EDP?s Executive Board of Directors, according to which such commitment is ensured by observing the following principles which guarantees compliance based on observance of the following principles: (1) Lawfulness and purpose; (2) Transparency and Loyalty; (3) Proportionality; (4) Monitoring; (5) Privacy from the very start; (6) Responsibility and (7) Safety. These principles are embodied in the different global data protection norms and procedures that address in particular: • the privacy by design processes • the risk assessments of processing activities and data protection impact assessments 

152 Part I Integrated Annual Report 2023 Performance | Sustainability • the management of processors • the process of responding to the exercise of data protection rights • the management of personal data breaches. These global procedures are complemented by specific procedures and controls defined at the level of each Business Unit for the entire life cycle of processing activities, according to their respective exposure to personal data protection risks. In their relationship with customers and other data subjects, the group companies provide information on the data processing carried out, either by themselves or by their processors, namely through the Privacy Policies available on their respective sites or informative disclaimers provided in contractual clauses or data collection forms. In these documents, the EDP group entities identify, among other aspects, the purposes for which they process the data, the respective grounds for lawfulness, retention periods, if applicable, whether the data is shared with other parties, as well as provide the contacts of the entity responsible for data processing and the contacts of the respective Data Protection Officer (DPO), through which data subjects can exercise their rights regarding personal data protection, request information or clarifications about their data and submit complaints. The management of this Specific Compliance Program is based on a specific governance model, based on the Compliance Management System, which establishes the responsibilities and the paradigm of relationship between the different stakeholders, with the coordination of the Compliance & Internal Control Global Unit, specific teams responsible for promoting the dissemination, knowledge, training, and implementation of the Compliance program in their respective areas of activity, and with the Internal Audit Global Unit, in the third line of defence, conducting specific audit work to verify the adequacy and effectiveness of the control mechanisms implemented. Whenever legally required, this Governance Model also includes a DPO. Regarding incidents with personal data, in 2023, the EDP group entities: • received a total of 614 Customer complaints (2022: 324); and • notified the respective control authorities of two breaches of Customers' personal data in Portugal (2022: 3) and one in Spain (2022: 2) Of these, were also communicated to data subjects, two data subjects in Portugal (2022: 1) and zero in Spain (2022: 0). Under the Personal Data Protection Compliance Program, a total of 9,183 participations were registered in the sessions provided in 2023, corresponding to a total of 3,965 training hours (2022: 11,619 employees/4,374 hours). In this context, the launch of the "The World of Data Protection" global learning stands out, with the objective of refreshing basic concepts, principles, and obligations regarding personal data protection. With regard to ongoing improvement initiatives developed in 2023, the following stand out: • the approval and dissemination of the revised and updated internal regulations. This revision aimed mainly at their updating, better systematization, clarification, and streamlining of procedures • the face-to-face training sessions with key interlocutors on the new procedures implemented in the revision of the regulations, also aiming at reinforcing topics whose maturity was intended to be strengthened • the continuous improvement of the Personal Data Protection Program Management Tool, highlighting the revision of the templates of some assessments with the aim of simplifying it and deepening its filling instructions. Prevention of criminal risks The Prevention of Criminal Risks Program was implemented, in a first phase, in the companies based in Spain (including a specific program at EDP Renováveis), following different reforms of criminal legislation in this country, which introduced and deepened the concept of criminal liability of legal persons with respect to certain offenses, also defining the requirements to be considered in the implementation of compliance models. The Compliance programs implemented in this context at EDP, meanwhile extended to other geographies with similar legal frameworks, provide the organization with a RECEIVED DIRECTLY FROM THE CLIENT REFERRED BY THE CONTROL AUTHORITY EDP COMMERCIAL CHANNELS DPO OTHER CHANNELS DPO Portugal 537 32 40 4 Spain 0 0 0 1 Brazil 0 0 0 0 

153 Part I Integrated Annual Report 2023 Performance | Sustainability management system that includes supervision and control measures to prevent the occurrence of crimes or mitigate the risk of their occurrence, mainly related to prevention corruption, bribery and other similar offenses (benefiting of synergies with other global Compliance programs such as the Integrity Compliance Program). EDP España and EDP Renováveis Compliance Programs regarding the Prevention of Criminal Risks are certified according to the UNE 19601:2017 Standard - Criminal Compliance Management Systems, certifications awarded by independent entities. Fair competition practices EDP promotes strict compliance with Competition rules, based on the commitments assumed in its Code of Ethics, its Integrity Policy, its Commitment to Healthy Competition and its Competition-related Specific Compliance Programme. Approved at the end of 2019, and transversal to all EDP group companies operating in Portugal, the Specific Compliance Programme for Competition Legal Obligations (SCP) aims to ensure strict compliance with national and EU competition legislation. For this purpose, it includes a set of specific tools, namely: • Competition Manual, which explains the basic concepts of Competition, the applicable rules, the impact of non-compliance, as well as the rules of conduct that all EDP group employees are obliged to comply with and enforce • Norm and Governance Model, which establish the relationship model, duties, and responsibilities of the various participants who act within the scope of the SCP • controls to mitigate competition risks, with periodic monitoring of compliance by the heads of the different business units, with the support of SCP Promoter • competition checklist and standard clause, to support the conclusion of contracts and/or agreements with suppliers, contractors, partners, and other entities • internal policies, standards, and procedures specific to the activities of EDP group companies, outlining the fundamental principles to be ensured in terms of Competition • specific training courses on Competition issues for EDP group employees, in particular the “100% Compliant – the Competition Game” e-learning course, which is part of EDP’s new employee onboarding programme, and the “Competition Quiz” e-learning course, both available to all employees in Portugal and with very high access and completion rates since their launch, and more recently a specific Competition module was included in a mandatory training for external service providers; and • other resources to raise awareness and publicize Competition issues, such as the Competition email to clarify doubts and support employees in implementing SCP, and communications aimed at employees who represent EDP in business associations, outlining the main rules of conduct. Every six months, since its implementation in 2020, the SCP is scrutinized, together with the different business units and other stakeholders, and evidence of their actions in accordance with the Competition rules is presented and validated. Improvements to the SCP are also identified and proposed, with a view to continuous improvement, which has made it possible to strengthen the EDP group’s compliance culture in the field of Competition. The year of 2023 was no exception and was marked by: • alteration and creation of new controls for the GEM Platform (the group's energy management platform), and inclusion of SU Eletricidade (electricity supplier of last resort) in the SCP, with the creation of specific controls for monitoring • on-site training on Competition Compliance, for a wide range of EDP Comercial (the group’s company that supplies in the liberalized market) employees, with a practical focus, adjusted to EDP Comercial's day-to-day business; and • approval by the EBD of the manual of procedures to be adopted in the event of on-site inspections, namely by Competition Authorities (OS 13/2023/CAE of 25 July), and subsequent training actions carried out by the Competition & Energy Policy and Legal & Governance departments. At present, two legal proceedings of a competition law nature are ongoing: • in the first case, EDP, S.A. and EDP Comercial were charged by the Portuguese Competition Authority (AdC) with entering an alleged non-compete agreement with Sonae MC - Modelo Continente. This decision was appealed before the Portuguese Competition, Regulation and Supervision Court (TCRS), which reduced the fines by 10%, to EUR 2.6 million and EUR 23.2 million, respectively. This TCRS decision was appealed before the Lisbon Court of Appeal (TRL) which, in April 2021, had ordered that the case be adjourned and referred to the Court of Justice of the European Union (CJEU) for a preliminary ruling. The CJEU handed down its judgement in October 2023. This court’s position is not binding and refers some points specifically to the TRL, which will now have to assess and hand down its judgement on the appeal against the TCRS judgement of September 2020. The decision is pending. • in the second case, EDP Produção was accused by the AdC of allegedly abusing its dominant position in the secondary regulation band market, with a fine of 48 million euros being imposed, and EDP Produção appealed against the AdC's decision to the 

154 Part I Integrated Annual Report 2023 Performance | Sustainability TCRS. This court upheld the conviction of EDP Produção, which appealed this sentence to the TRL. In a judgement handed down in September 2023, the TRL partially rejected the appeal filed by EDP Produção, confirming the TCRS judgement, although it upheld the appeal regarding the reduction in the amount of the fine imposed on EDP Produção, reducing it to 40 million euros. Faced with this decision, in October 2023 EDP Produção filed an application with the TRL arguing that the judgement had been flawed in a number of ways and filed a request to appeal to the Constitutional Court, raising the unconstitutionalities argued throughout the process. In December 2023, the TRL rejected the invalidations invoked by EDP Produção, and EDP Produção submitted a request for clarification of part of the judgement. A decision is pending on this request for clarification, as well as a decision by the Constitutional Court on the admissibility of the appeal and notification to submit written arguments. Nonetheless, in the context of this case, EDP Produção has already been legally obliged to pay the fine to which it was condemned by AdC even before the judgement and final decision of the TCRS. Following this case, the Ius Omnibus Association filed a popular action, anchored in the AdC's decision, claiming the payment of compensation to all consumers in Portugal who were allegedly harmed. This case is suspended until a final decision is taken in the administrative offence case brought by AdC. • EDP is fully convinced that, in both cases, no offence was committed. • it should be noted that a similar approach to preventing and mitigating practices that restrict competition is being implemented for the remaining countries, without prejudice to the codes and manuals already in place. Internal Control System for Financial Reporting (ICFR) EDP, within the scope of its financial reporting obligations, has an Internal Control System for Financial Reporting (ICFR), consisting of a model for the evaluation and mitigation of financial reporting risks, through the monitoring of the execution of control activities and the identification of potential improvement actions and their implementation. The EDP group's ICFR was developed and implemented based on the criteria established by the internal control regulatory framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO 2013") in relation to business processes and overall controls, and by the Control Objectives for Information and related Technologies ("COBIT") in relation to general information technology controls. In 2023, the ICFR mapped and monitored a total of 3510 controls that contribute to mitigating the risks in Financial Reporting, including those of fraud and information systems. Annually, the ICFR is audited by an external independent entity, and since 2010 it has been considered, in all materially relevant aspects, an appropriate and effective internal control system and is certified by the external auditor without conditions and comments. 3.4.12.3. Responsible political involvement Representation of interest EDP group institutional engagement and external affairs are managed in accordance with legal requirements and in line with the principles of action established in the Code of Ethics, Integrity Policy and other internal provisions of the company governing its relations with stakeholders, in particular those of integrity, transparency and responsible political involvement. 2023 was the year for the implementation of the new Policy of Representation of Interest, implementing its Principles for responsible political involvement: It prohibits any contribution or association of the EDP brand to political parties, candidates, political campaigns/candidacies or to related people or entities. This covers the direct or indirect delivery of goods or provision of services on behalf of, or representing, EDP. It also includes the prohibition on using EDP resources for actions related to political processes. None of the group’s companies have made monetary contributions or contributions in kind to political parties, although permitted in some of the legal regimes in countries where the EDP group operates. Nevertheless, EDP participates in public decision-making processes, and engages in activities with various national, European and international institutions, with a view to conveying to public bodies their legitimate interests and/or those of the sector, which it considers worthy of consideration within the scope of legislative processes. These activities include: 1\. Awareness of specialized people and institutions EDP Renewables undertakes awareness activities for specialized individuals and institutions according to local legislation. In addition, in accordance with US law, and at the request of US employees, EDP Renewables North America (EDPR NA) provides duly regulated mechanisms for the participation of employees in political processes and has established a policy action committee (PAC) called "EDPR NA PAC". The EDPR NA PAC is funded entirely by 

155 Part I Integrated Annual Report 2023 Performance | Sustainability voluntary personal monetary contributions made by members of the PAC, who are employees, according to US law. Decisions on which political campaigns to support are made with the approval of the PAC's Board of Directors, whose members are elected PAC members, also in accordance with US law. The activities representing the interests of EDPR mainly involve the following awareness- raising initiatives, presented below which exclude the amounts under EDPR NA PAC. • Contributions to America Energy Action activities EDP Renewables North America contributes to the activities of America Energy Action, a social welfare organization established under Section 501(c) (4) of the US Federal Internal Revenue Code. This type of organization can legally participate in political activities by defending or opposing candidates for public office. However, these kinds of activities must be absolutely independent of specific candidates or campaigns: they can be undertaken for ideas, concepts or public interests. • Contributions to Non-Governmental Organizations (NGOs) EDP Renewables North America works with a number of organizations with social or environmental objectives, pursuing goals aligned with support for decarbonization and the transition to a low carbon economy. This type of organization can support a candidate with its own funds, but its communications cannot be coordinated by a political party, campaign, or candidate. • Procurement of lobbying services EDP Renewables North America has lobbying consultants operating with the US Government and in some US states. These political consultants are prohibited from making contributions to candidates or political parties and campaigns on behalf of EDPR NA, to ensure that their activities never violate the prohibition on making political contributions, established with the EDP group. 2\. Participation in the main European or international Sectoral or Industrial Associations During 2023 EDP sought to raise awareness among the various stakeholders in the context of the European institutions (European Council, European Parliament and European Commission) on a number of issues central to sustainability in the field of energy, either proactively or as part of public consultations, leveraging on the advocacy activities of associations. The long-endured Energy Crisis aroused by the eastern war inflicted by Russia led to an acceleration in the EU commitments to the sustainable transition and the phase-out from fossil-fuels, a final definition of a number of legislative files within the fit for 55 Package as well as of the Electricity Market Design , reinforcing EDP group’s participation within the main European sectoral associations, in particular Eurelectric, WindEurope, Solar Power Europe, EASE, ChargeUp Europe, European Distribution System Operators (E.DSO) or the European Federation of Energy Traders (EFET). At the same time, to promote the development of the energy sector, its sustainability and efficiency, EDP strengthened alliances with similar parties to establish macro platforms for joint public positions that reflect the vision of the sector as a whole vis-à-vis the major decarbonization commitments undertaken internationally. In this context, we’re highlighting the renewable hydrogen implementation efforts: • Letter to the European Council and Parliament on the Delegated Act for RFNBOs • Letter on the urgent Adoption of the Renewable Hydrogen Directive • Letter to EU Finance Ministers in order to call for an EU approach to the financing of renewable hydrogen and of course the multiple contacts with decision-makers in different institutions seeking to contribute to opinion-forming and communicating the company’s views on such wide-ranging and decisive issues as the Market Design, Permitting, European Funds, and Biodiversity. Membership and activity undertaken in global associations such as: • the World Economic Forum, where its first year as partner was deeply engaged on the world paths to netZero, also engaging in cyber security; grids and storage; the World Business Council for Sustainable Development group (WBCSD) • or at European level such as Eurelectric • or yet at national level, in the different geographical areas, such as the Portuguese Association of Electricity Sector Companies (Elecpor), the Spanish Association of Electric Energy Companies (Aelec), The Brazilian Association for the electrical grid (Abradee) , The North American Solar Energy Industry Association, The American Energy Action, and others, clearly identify the shared and constructive path that the EDP group continues to build, advocating sound climate action, world sustainability and security, all aligned with EDP’s Human and Labour Rights Policy. 

156 Part I Integrated Annual Report 2023 Performance | Sustainability Advocacy to combat climate change: The persistent advocacy in all representations of the Climate positioning, following the Paris Agreement as stated throughout EDP’s policies and public commitments, is mapped in the group’s Strategy, mirroring the transparent, scrutinized, and constructive positioning of the EDP group's growth. In 2023 EDP publicly updated its UN Energy Compact “All green Energy by 2030” restating its commitments to 100% renewable energy by 2030 and coal free by 2025, while promoting access to energy and decarbonizing its value chain with the commitment to be Net Zero by 2040. EDP joined the WEF based CEO Climate Leaders Alliance a CEOs led initiative across sectors scaling ambition on climate action to encourage policy makers to support bold climate action by setting ambitious targets, taking collective action, reducing own emissions, and inspiring others to do the same. Ahead of UNFCCC COP28 in Dubai EDP signed COP28 Open letter where members of the CEO Climate Leaders Alliance call for policy changes that can drive outsized impact and subscribed the policy letter and campaign calling for fossil fuel phase out “Fossil to Clean” mobilized by the We Mean Business Coalition (WMBC) and supporting partners aiming to send a clear message that businesses are taking action to accelerate the deployment of clean technologies and reduce emissions – and that business can go even further with bold political leadership at COP28 and beyond. It was also towards COP28 that EDP supported the Global Renewables Alliance positioning, that deeply impacted COP’s themes pushing Renewables on the Energy transition. The preparation of Davos Annual Meeting in themes like Cybersecurity or Solving for net zero through industrial Clusters, or yet the Hydrogen Acceleration, built up to behaviour and positioning commitments among energy utilities in all of these fronts, fulfilling the corporate strategy on leading the energy transition, by creating superior value on a path aligned with the ambition of the Paris Agreement. The 2023 commitment towards a NetZero planet can be identified at the 70% of the TOP10 Interest Representation being relevant and involved work on Climate position Organizations, through an investment of 2.140 k€. From our selected TOP10 representations of interest, 94% of the work was taken through Business or Sectoral Associations, and none through lobbying. 3\. The direct or indirect Involvement of employees appointed/designated for this purpose At European level, the transparency of lobbying activities carried out by appointed lobbyists is ensured through the publication of their activities in the European Union Transparency Register, a public register in which organizations representing specific interests in the European Union register and provide up-to-date information on these interests. Internally, EDP group has developed a Stakeholder Relationship Policy, with the definition of principles and guidelines for interaction with strategic groups, in particular Employees and Politically Exposed Persons and, based on four guiding commitments: Understand, Communicate, Trust and Collaborate. There is also an internal compliance platform for registration with PEP; another to record actions and contacts established (TRUST) and a shared map of EDP's external representations in society, the “Impact Map”, that centralizes all external representation at EDP, defining which is Representation of Interest and of what kind. This tool was formalized and made a managing procedure by the Interest Representation Policy mentioned above (June 2023). Value of the activities of representation of interests For the year 2023, the costs of representation of interests were under 6.8 million euros and were deeply related to the decarbonization of the economy, electric mobility, energy efficiency and security of supply. Reinforcing the facing of a long-endured energy crisis was a strategic focus, bringing Renewable Energies as key to guarantee Independence. The focus of advocacy work with the main national energy sector associations (UNESA, Eurelectric, American Wind Energy Association and TDA), above all, dwelt with the European Green Deal and market design, the National Climate and Energy Plans of the member states and biodiversity as a whole.

157 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.12.4. Tax transparency The fiscal footprint of EDP Group EDP Group is a utility present in 4 regional hubs, whose value chain includes the activities of generation, transmission and distribution and supply of energy. These activities trigger various types of taxes, levies and financial contributions which, when considered as a whole, determine the level of taxation to which the EDP Group is subject. Of all the phases in the EDP value chain, its energy production activity is the one that contributes most significantly to the payment of taxes and other contributions. Global contribution of the EDP group In 2023, EDP Group’s global tax contribution to the public revenues of the countries where it is present amounted to approximately 2.9 billion euros, of which 0.9 billion euros correspond to own taxes and contributions borne (paid) by the EDP Group and circa 2 billion euros of taxes collected (contributions to the States on behalf of other economic agents), as shown in the following charts. Taxes borne (paid) by EDP Group, by geographical area 28% 24% 19% 9% 6% 5% 4% 5% Spain Brazil Portugal Italy United States Poland Romania Other €0.9 billion in 2023

On the other hand, considering the taxes incurred by EDP Group, the most relevant amount (41%) concerns to corporate income tax, followed by specific taxation on the energy sector (including the windfall tax paid in Spain, Romania, Italy and Poland) (22%), and, finally, social security contributions borne by companies (17%). Regarding corporate income tax rates, the nominal tax rates in the main countries in which EDP Group operates range between 16% in Romania and 31.5% in Portugal, adding municipal and state surtaxes to the nominal rate in the case of companies located in Portugal. In Portugal, the taxes borne (paid) in 2023 amounted to 180 million euros, emphasizing the weight of corporate income taxes amounting to 74 million euros, as well as social security contributions borne by the companies amounting to 78 million euros. In Spain, the taxes borne (paid) in 2023 amounted to 258 million euros, where the specific taxation on the energy sector should has the highest weight amounting to 116 million euros, followed by corporate income taxes that amounted to 88 million euros. 41% 22% 17% 9% 9% 2% Corporate income tax Energy taxes Social Security contributions Property tax Non-deductible VAT and similar Other taxes €0.9 billion in 2023 51% 28% 19% 2% Portugal Brazil Spain Others €2 billion in 2023 34% 4% 38% 17% 7% Consumption Tax Social Security Contributions Payable by Workers Withholding tax (third-party income) Energy taxes Other €2 billion in 2023

161 Part I Integrated Annual Report 2023 Performance | Sustainability Specific taxation on the energy sector in 2023 The specific taxation on the energy sector carries significant weight within the EDP Group. In 2023, the EDP Group incurred taxes of this nature amounting to 206 million euros, as shown in the following graph. Indeed, in the year 2023, several European countries maintained or enforced the so-called "windfall taxes", which originated from Council Regulation (EU) 2022/1854 of October 6, 2022, establishing emergency intervention measures at the European Union level to address high energy prices. These measures included, among others, the introduction of price cap mechanisms for market revenues obtained by electricity producers from, essentially, renewable energy, and a temporary solidarity contribution applicable exclusively to companies active in the crude oil, natural gas, coal and refining sectors. Although the rules contained in this Regulation are aimed to create standardized measures in the European Union in response to the energy prices rise, certain countries where the EDP group is present have introduced unilateral measures, giving rise to the payment of windfall taxes in Spain, Romania, Italy, and Poland. While EDP fully acknowledges that the existing emergency situation required for extraordinary measures, the Company also considers that (i) the principle of not taxing unrealized extra-profits should always prevail and (ii) the compatibility with existing, legitimately implemented, risk management strategies, needs to be ensured. These requirements are necessary to avoid harming producers that do not actually benefit from the current high electricity prices, due to having hedged, individually or at Group level, their revenues, against fluctuations in the wholesale electricity market. These financial hedges follow the Company’s established low risk strategy to secure long term revenues and to remove electricity prices volatility on the company’s earnings. For these reasons, EDP will pursue all legal actions at its disposal in order to challenge the legality of these measures. The introduction of this tax in Spain resulted in the payment of 48 million euros by the EDP Group in 2023, making this country bear the highest level of energy taxation, representing about 57% of the total amount paid by the entire EDP Group. At the same time, there was a very significant decrease in the value of energy taxes paid in Portugal and Romania. In the case of Portugal, the reduction in terms of taxes paid was mainly due to (i) the suspension of the mechanism to restore competitive balance between electricity producers operating on Portuguese territory and electricity producers operating in Spain (known as clawback), (ii) the postponement of the collection of the amount corresponding to the social tariff for 2023 (which will be collected at the beginning of 2024, as stated in ERSE Directive 1-2024 of January 9, 2024), and (iii) the decision not to pay the CESE, whose constitutionality is being legally challenged by the EDP Group. In the case of Romania, the amount of tax paid decreased by approximately 69 million euros, as from March 2023, because the requirements for the application of the windfall tax in that country were no longer met. 11% 56% 13% 13% 7% Portugal Spain Romania Italy Other €206 million in 2023 

162 Part I Integrated Annual Report 2023 Performance | Sustainability 3.4.13. Innovation and digital transformation 3.4.13.1. Transforming our business DGU’s mission for business transformation EDP's Digital Global Unit (DGU) has the mission to shape a global technological strategy and vision for the organization, transforming how the business delivers value by seamlessly integrating digital technology. DGU plays a key role in managing the complexities of energy systems, focusing on three priorities to accelerate digital and technology adoption: (1) consolidate business proximity for a global digital operation; (2) enhanced data and digital ambition, ensuring a group- wide digital strategy, and increasing digital maturity; and (3) ensure a high-quality and secure digital ecosystem. In 2023, DGU concentrated on strengthening data fundamentals and adopting emerging technologies, contributing to EDP's digital ambition by democratizing AI adoption and advancing data analytics. These efforts set a strong foundation for furthering EDP's digital goals, promoting disruption, maximizing value, accelerating Data & AI adoption, and expanding digital practices across the organization. Digital strategy as driver to energy transition The digital strategy is paramount in partnering with the business to tackle key challenges and generate value. Digital transformation is an enabler and accelerator for EDP to lead the energy transition across all its operations. Building on the ambitious goals outlined in the 2021-25 strategic plan, EDP has set even more ambitious digital KPI´s for the 2023-26 period. This decision is driven by positive forecasts and the significance of measuring the Digital contribution. As of 2023, certain Digital KPI´s are heading well towards the targets set for 2026, as per: DGU and digital transformation To accelerate digital transformation EDP has committed to invest a total of ~€2 billion Digital TOTEX in 2023-26 to meet the targets for the period: • 85% energy assets with advanced analytics • 100% businesses with artificial intelligence • 95% processes digitalized. EDP's digital transformation extends across all businesses and geographies, to digitize processes, tools, and the ecosystem for enhanced agility and efficiency. This inclusive journey involves active participation not only from EDP's people but also from partners and suppliers, all contributing significantly to the desired digital acceleration at EDP. EDP´s digital transformation journey is powered by four strategic priorities: • a Global DGU, closer to business • focus on a people-centric organization • push on digital-first culture • excel in delivery and cyber. During the year, ~200 digital and technology projects were managed with cross-business and geographies impact.

163 Part I Integrated Annual Report 2023 Performance | Sustainability Global DGU, closer to business DGU continued its journey to become a truly global team, with global functions, hubs, and teams to deliver value and increase proximity across the value chain. In 2023, several strategic projects were implemented to improve communication between digital and business teams, pursuing high business-value solutions with increased synergies and simplification: • DGU Now: Initiated a program to reshape DGU's organizational model. This involves redefining DGU's operating model, governance mechanisms, operational models for hubs, and people strategy. The goal being to enhance alignment across Global functions, platforms, and hubs, strategically positioning digital at the core of EDP’s overall strategy • Digital Roadmap: A Digital Roadmap from 23 to 26’ was created seeking to have an aligned digital vision, focused on higher business value and engaging the organization toward the digital transformation • Agile Squads: allocation of dedicated global resources to work close to business units, ensuring continuous alignment with the business throughout the development of new solutions, driving delivery speed and quality • Reference Architectures: defined a set of reference architectures to allow the business to have higher flexibility and faster development in adding new products/services and introducing innovations, with reduced costs and lower architecture disruption. In 2023, the focus was on Client Solutions, Data & AI Strategy and Governance, Generative AI, Integration, Master Data Management and Monitorization reference architectures. Focus on a people-centric organization EDP’s vision is to create a global human-centred organization and acquire and train talent with new and upgraded skills for critical roles. To enable the organization’s readiness to adopt a more digital mindset, EDP has taken action to place people at the heart of the transformation, by investing in the development of digital skills of its people at all professional levels: • GenAI workshops: held of a series of workshop sessions to push GenAI democratization across the group, reaching EDP’s Top Management (+50 participants) and the Digital Global Community (+800 participants) • Training & Certifications: achieved a maximum number of certifications in a year at EDP, with a total of +500 certifications, most being delivered in critical technologies for the future (e.g., Cloud and Data) • Leadership Training: DGU launched a training program for leaders to cascade down through their teams at all levels, to introduce the DGU new operating model and ways of working, aligned with the group´s Global People Development Strategy. Push on digital-first culture EDP invested in creating a digital organizational culture and mindset, both by (1) promoting digital awareness and maturity across the company’s leadership, with immersive training programs including top management involvement, and (2) developing and improving the key data & AI foundations to accelerate digital impact, with the implementation of new data lakes/hubs and new analytics solutions. In 2023, the main highlights were: • Digital2Leaders: boosted digital culture across top management, by pushing digital awareness and establishing a common lexicon • Digital Global Community: virtual community that promotes collaboration and knowledge on digital technologies and methodologies (e.g.: Agile, Blockchain, Cyberse- curity, Data & AI, High Tech…), currently with almost ~2,000 members • IoT Platform: significant push of IoT Use Cases implementation and cross-pollination, with three global references in production • Data & AI Governance: defined a global strategy to guardrail AI ramp-up at EDP and implement data governance across geographies and platforms • GenAI Program: defined the golden rules for deployment of Generative AI solutions and created a pipeline of priority use cases to implement in 2023-24, with +five initiatives undergoing implementation 

164 Part I Integrated Annual Report 2023 Performance | Sustainability • Open Data Portal: implemented a portal that allows main stakeholders (e.g., universities, municipalities, energy producers and developers) to have regular and organized access to data, to deliver value to society and foster innovation. Excel in delivery and cyber In 2023, EDP has made significant progress in ensuring that its landscape is future-proof, through the implementation of (1) a multi-cloud strategy, with the gradual migration of apps to cloud, (2) parallel initiatives to optimize cloud storage, and (3) a secure ecosystem, with a robust response system to block or resolve any cyber threats. Main highlights in 2023 include: • Strategic Tech Partnerships: consolidated partnerships with a pool of tier-1 global strategic tech partners to build cutting-edge solutions, to power tech evolution and modernization of the application landscape • Simplifica Program: implemented S/4HANA in Brazil, following a greenfield implementation strategy which covered~80 companies of the group and impacted 100% of the business processes and interfaces with business systems • All Cloud Program: continued the journey to achieve a future-proof multi-cloud architecture and generate flexibility, scalability and application management autonomy. By the end of 2023 EDP had migrated +80% of all apps to the cloud • All Cyber – Defend EDP as one: building a cybersecure organization ensuring a global and robust threat monitoring and response processes. The program has acted on three domains: (1) definition of cybersecurity organizational model (i.e., roles, processes, governance), (2) creation of a framework to ensure documentation and information security, and (3) establishment of global cybersecurity metrics and KPIs. 3.4.13.2. Development of innovative technologies Overview Innovation has long been a traditional investment priority for EDP, with EDP Inovação (EDPI) as the key promoter for innovation within the group. It was established in 2007 with the objective of creating an autonomous entity responsible for internal innovation activities as well as fostering stronger links with the entrepreneurial ecosystem. EDP's innovation operating model is based on a fast adopter logic with a well-defined purpose of accelerating new businesses with impact and promoting the rapid adoption of innovative solutions to lead the energy transition. It seeks to solve the energy transition problems through the integration of new technologies, processes, and products, as well as innovative business models in EDP´s business to enhance competitiveness and create value for stakeholders. EDPI follows an Open Innovation philosophy that engages and promotes adoption through three innovation paths that act in parallel and complementary to one another, fed by a transversal sourcing process, namely: internal delivery (innovation portfolio developed internally), external partnerships through the open innovation ecosystem (start-ups, corporates, universities, among others), and external investments through EDP Ventures. Innovation strategy to be delivered thoughout three innovation avenues These innovation avenues are supported by the right funding and investment, coordination, and expertise development to ensure EDP is at the forefront of market trends and innovation. EDPI also ensures the development and management of the infrastructure to disseminate innovation culture and best practices across the organization, fostering both entrepreneurship and intrapreneurship. EDPI focuses on seven (+one) innovation domains aligned with corporate strategy and market trends, which positions EDP along the energy industry value chain. • Renewable energies, their integration and flexibility, to help EDP achieve its renewable energy targets • Networks, an enabler of the energy transition • Distributed energy systems that support B2B and B2C customers in developing their distributed generation solutions 

165 Part I Integrated Annual Report 2023 Performance | Sustainability • Green hydrogen to support the energy transition in sectors whose activity is preponderantly dependent on carbon-emitting solutions • Energy storage and flexibility, which tests new storage technologies, flexibility management • Sustainable mobility, which supports EDP customers in their transition to electric mobility and provides associated services • Decarbonisation of energy uses, which supports EDP customers' decarbonisation efforts by developing new solutions and speeding up their adoption Moreover, EDPI continuously searches for new solutions. The “Open Box” domain creates space for ideas/projects to be developed that do not fit rigidly into any of the other domains. 2023 in summary After defining the structure in 2021 and consolidating the innovation model in 2022, the year 2023 was marked by the execution of the defined strategy. EDP Innovation aligned and prioritized its areas of opportunity in their respective domains, focusing the team and reinforcing it to expand opportunities throughout the innovation funnel. In 2023, the editions of Free Electrons and Energy Starter in Dublin, Sydney, Mumbai, Houston, Lisbon, and Santander stood out, along with the significant presence of EDP teams at the Web Summit, bringing EDP's innovation and message to the largest global conference of Innovation and Technology in both Rio de Janeiro and Lisbon. In the investment scenario, the year was particularly exciting, with new companies in the portfolio totalling approximately €14 million in investment. 

166 Part I Integrated Annual Report 2023 Performance | Sustainability Internal delivery This year marked the second year of the current internal incubation process, in which a portfolio was developed from internal sources (although it was explored both internally and externally). This method was supported by a funnel approach, aiming to mitigate the risk of opportunity to expand solutions and businesses, aligned with EDP's strategy and priorities. In 2023, ten new emerging business opportunities were submitted to the global innovation decision committee for evaluation, totalling 30 since the implementation of the current Innovation model. Among these 30 opportunities, 21 were chosen based on their innovative merit and competition for resources among them. Of these, nine were discontinued in the Validation phase and four in the Construction phase, while the remaining seventeen impactful projects are currently in progress. We concluded the year 2023 with eight projects in the construction phase. Below are some of the projects in the funnel: • In the validate phase: • The Scale up O&M project aims to automate the operation and maintenance processes of solar parks, particularly in activities such as aerial inspections, vegetation cutting, and panel cleaning. The main goal is to improve overall solar production and reduce the OPEX of solar plants. • In the build phase: • The Going Net Zero project – with the objective to help C&I customers to decarbonize by a digital platform able to offer fully automatized one fits all emissions assessment and reporting with advisory-based service, able to prescribe detailed reduction plans. • The Automating PVs Installation project – with the objective to incorporate advanced solutions to automate critical construction tasks of utility-scale solar PV power plants. Relevant cost savings can be achieved by a mindset shift of the installation process from construction to manufacturing. All these 21 EBOs involved nine different EDP business units and more than 100 people across geographies. Open ecosystem In 2023, we carried out Open Innovation programs, such as Free Electrons (founded by EDP, now in its seventh edition, with a total of over 4,000 startup applications and over 80 million dollars in investment) and Energy Starter programs, executed in multiple geographies, as well as conducting pilot projects with startups. Currently, we have a total of 19 pilots resulting from programs promoted by EDP Innovation and three commercial rollouts approved by EDP with startups from previous editions. Among the various programs in which EDP was involved in 2023, such as AWS Clean Energy Accelerator, DeepTech Alliance, SOL Energy Transition, and SOL Mobility, over 1,200 startups were evaluated, and over 100 meetings were held to explore opportunities with startups. • In 2023, three in-person events of the Free Electrons program were held in Dublin, Sydney, and Mumbai. In this edition, we had the participation of over 60 EDP employees and received over 750 startup applications, with the selection of a group of 15 startups. • Throughout the year, the Energy Starter program was restructured in line with the recent innovation model and business strategy of EDPI, comprising three verticals: Networks, Renewables, Green Hydrogen, and Customer Solutions. The program featured in- person events in Houston, Lisbon, and Santander, with 28 startups selected for the three tracks of the program. The program also included an Open Day in Lisbon, involving over 170 participants from the local innovation ecosystem and over 600 who attended online.

Ventures Increasingly focused on strategic investments to meet the renewable energy generation goals of the EDP group. In 2022, EDP Ventures altered its investment strategy, shifting from a minimum ticket size of 250,000 euros to 1 million euros to a higher range of 1 million euros to 10 million euros. • In 2023, we invested 14 million euros, reaching a total accumulated investment of 70 million euros. • We added four new companies to our portfolio: • Terabase: developed Terafab, the world's first automated field factory for large- scale solar construction • Mixergy: developed an intelligent water heater that uses artificial intelligence to significantly improve efficiency and costs, acting as a residential battery • Captura: developed a carbon dioxide removal (CDR) system based on the natural capacity of ocean CO2 absorption • Splight: a platform that implements AI solutions to optimize the integration of Renewable Energy Sources (RES) into any type of grid • We successfully completed the divestment of four companies from our portfolio, achieving a total of nine successful divestments. The Total Contract Value between EDP and portfolio companies in 2023 was 20 million euros, with a total accumulated value of over 115 million euros and 39 active companies in the portfolio. • We had new additions to the team, and currently, over 30% of our team is composed of female professionals. The work of EDP Ventures did not go unnoticed; it was recognized as Corporate Startup Stars by Mind the Bridge/ICC, due to its strategically impactful investments in the EDP group. Additionally, we were ranked as the 8 th largest global investor in Renewable Energies in the Pitchbook ranking from 2018-2022, and our managing partner, Luis Manuel, was included in the "Top 100 Powerlist" of the Global Corporate Venturing ranking. Innovation enablement and expertise In 2022, there was a significant dissemination of the culture of innovation throughout the organization: EDPI initiatives reached 830 FTE of internal audience (with 15% participation in more than one initiative) and over 1,482 colleagues from 29 business areas and 22 different countries through our online Global Innovation Community. Below are some of the highlights for 2023: • The 2023 Innovation Immersion Program in Singapore had 17 participants from 13 business areas and five geographies, representing our most diverse group to date. The program included 22 networking sessions, generated 305 learning opportunities, and 81 qualified business leads. It stood out for its emphasis on communication, with the team dedicating resources to its promotion. For 2024, the team is considering a new innovation hub, possibly in the APAC region or the United States. • The Global Innovation Community, with its over 900 subscribers from 15 countries and 22 business areas. In 2023, it hosted 26 live sessions. Since its launch in February 2022, we have had the participation of over 1,500 attendees. • Participation in the Web Summit conference (Rio de Janeiro and Lisbon) driving the culture of innovation throughout the organization. At Web Summit Rio 2023, EDP had a delegation of 49 colleagues from EDP Brazil and 9 business areas. At Web Summit Lisbon 2023, we brought over 134 colleagues, and EDP focused on seeking promising startups and showcased six major projects at its booth. We identified 522 opportunities in 65 technologies, representing a 160% increase since 2022. Our showcased projects gained significant visibility, reaching over 3,500 participants, and generating approximately 1,500 qualified leads. Additionally, we held two talks on the Web Summit stages. We now look forward to the next edition in Rio, Latin America. • The Groundbreakers team brought together 110 colleagues from 13 business areas and the five EDP innovation hubs at the second in-person meeting of the Global Innovation Team. • The first edition of the "The Spiral" program, a tool to strengthen the culture of innovation and internal entrepreneurship. In this edition, we received over 60 registrations, selected ten finalists, and saw a high level of engagement from the organization. • The "Somos Play" program, an intrapreneurship program that takes place in Brazil, had seven projects implemented by the organization. • Innovation Learning Experience (ILE), a global learning program in collaboration with EDPU that provides a distinct experience, valuing participants who effectively apply their learning in innovation projects at EDP.

Creation of a long-term value We address the path of sustainability by facilitating the long-term investment in companies. This means to channel the capital into sustainable assets. Since 2004, with the join to the UN Global Compact (UNGC) and the approvement of EDP group’s Principles of sustainable Development, EDP has announced publicly the commitment to carry on its business while seeking a balance between the economic, environmental, and social aspects of the company’s activity and pursuing an approach that incorporates the priorities of their stakeholders. In 2023, the economic value generated by EDP was 18,296 million euros, compared to 22,661 million euros in 2022. This value includes turnover and other income. In 2023, 84% of the Generated Economic Value (GEV) was distributed in a total amount of 15,368 million euros. The aggregated economic value (AEV), the difference between the GEV and the Distributed Economic Value (DEV) corresponds to the remaining 16% and includes retained earnings and non-payable costs. Economic value generated (€M) 3.4.14.2. EDP ESG performance assessment During 2023, EDP has carried on the efforts of providing ESG data (qualitative and quantitative) to several ESG analysts as a tool for managing risk because the company's long-term success depends on its sustainability performance. The company's commitment to sustainable practices continues to be revisited by analysts (climate change, policy commitments, worker safety, diversity, governance and other ESG factors), based on each in-house methodology. This explains why scores, ratings and/or level of risk obtained based on different ESG performance indicators, such as GHG emissions or violations against the UN Global Compact (UNGC) used by the different analysts are not comparable with each other. It should also be noted that the group has responded to questionnaires that grant recognition in the areas of climate change and water management (CDP Climate Change and CDP Water Security), in sustainability (S&P Global CSA) and in ethics (Ethisphere Institute). Additionally, some of the group's subsidiaries provided answers to particular assessment surveys: ECOVADIS - EDP Renováveis, EDP Comercial e EDP Espanha. 2,136 2,285 2,928 14,344 20,375 15,368 16,480 22,661 18,296 2021 2022 2023 Distributed Economic Value Accumulated Economic Value

Facts & figures of sustainable finance Since the 2030 Agenda for Sustainable Development and the historic signature of the Paris Agreement, there have been made important progress in the battle against climate change and towards a greener, more resilient, more inclusive global economy. Sustainable finance has the potential redirect the funds to climate action, transition to a climate-neutral economy and towards an environmentally sustainable economy, namely a circular, zero pollution, nature-positive economy and sustainable use of water and marine resources. The European Commission's regulatory framework supports this path through three main instruments: the taxonomy regulation (available at the link), the regulation of EU benchmarks for the climate transition and EU benchmarks aligned with the Paris Agreement (available at the link) and the regulation of the issuance of green bonds (available at the link). Figure Financing the transition to a sustainable economy (Adapted from the recommendations from European Union) According the last report of the Global Sustainable Investment Alliance – GSIA Report 2022 (available through the link) the global sustainable investment reached USD30.3 trillion in six major markets (Europe; United States; Canada; Australia; Japan and New Zealand)-. That amount, which excludes the US owing to methodological adjustments, corresponds to a 20% increase in sustainable investments (from 18 trillion US dollars in 2020 to 22 trillion US dollars). In Europe, there are 38% (or 42% in 2020) sustainable investments out of the total global assets under management. The decrease is a result of increased scrutiny brought about by European regulations, including the SFDR (available at the link) on the disclosure of sustainability-related information in the financial services sector. Investors The “Glasgow Financial alliance for Net Zero (GFANZ)” established in November 2021, which assembled a few of the world’s most powerful financial institutions to fight global warming, by pledging to bring loan and investment portfolios to net-zero by 2050 and currently made up of 675 members from more than 50 countries, has continued to develop its work in 8 main sectors: Net-Zero Asset Owner Alliance (NZAOA); Net-Zero Asset Managers Initiative (NZAM); Paris Aligned Asset Owners (PAAO); Net-Zero Banking Alliance (NZBA); Net-Zero Insurance Alliance (NZIA); Net Zero Financial Service Providers Alliance (NZFSPA); Net Zero Investment Consultants Initiative (NZICI); The Venture Climate Alliance (VCA). However, as the year unfolded, sustainable finance had to stave off a backlash against ESG policies. At the end of 2022, Vanguard group, the world’s second-largest asset manager and a major index investor, pulled out the GFANZ, saying it aims “provide the clarity our investors desire about the role of index funds and about how we think about material risks, including climate-related risks.” Regulators The first report of financial disclosures about the corporate sector's shareholding climate for monetary policy purposes, following the measures announced in 2022 (the purchase of corporate bonds and the pandemic emergency purchase programme according to a climate score based on three factors: backward-looking emissions (issuers’ past emissions), forward-looking targets (issuer’s ambitious decarbonization targets) and climate disclosures (issuers’ reporting of greenhouse gas emissions: scope one, two and three), was released by the European Central Bank (ECB) in 2023 and may be accessed via this link. Within the European regulatory framework, the following facts are critical for sustainable financing in 2023: January 2023 \- coming into force of the sustainability reporting directive (CSRD available on the link). This regulation replaces the Directive 2014/95/EU on reporting non-financial information. Large listed companies are required to report under the new ESRS (European Sustainability Reporting Standards, available on the link). They are part of the first group of 

173 Part I Integrated Annual Report 2023 Performance | Sustainability users of the CSRD. They will have reporting requirements for the 2024 fiscal year starting in 2025.June 2023 - amendments to the 2020 Taxonomy regulation (available at the link): a) the introduction of technical assessment criteria to determine under which conditions an economic activity qualifies as contributing substantially to the sustainable use and protection of water and marine resources, to the transition to a circular economy, to the prevention and control of pollution or to the protection and restoration of biodiversity and ecosystems, and to establish whether that economic activity does not significantly undermine the fulfilment of any of the other environmental objectives; b) amendments to regulation 2021/2078 on compliance with Article 8 of the Treaty on the Functioning of the European Union. June 2023 \- changes to the environmental taxonomy's regulation as a result of establishing additional technical screening criteria for determining the conditions under which certain economic activities qualify as contributing substantially to climate change mitigation or climate change adaptation (link). November 2023\- publication of the EU Green Bond Standard Regulation in the Official Journal of the European Union (available on the following link) December 2023 – publication in the Official Journal of the European Union the sustainability European reporting standards (available here) EDP Impact of ESG performance measurement EDP has demonstrated its expertise in ESG matters and its knowledge to reply to investors who follow active and passive investment approaches. Additionally, regarding the financing component, the group has responded to requests from investors, who are increasingly demanding in terms of mitigating the risks inherent in ESG factors. EDP Sustainable Finance Considering that EDP must comply with the sustainability reporting mandate and report sustainability in 2025 for the fiscal year 2024, the company feels the significant pressure in terms of set up an Internal Control System for Sustainability Reporting (SCIRS). While it is not currently required, there are advantages to it, such as: a) ensuring the validity, completeness, and accuracy of the sustainability information reported; and b) ensuring the transparency and confidence of the processes used to produce, process, and communicate the information for reporting. EDP therefore concluded the year with the development of a project that would ensure that it has the key elements of the Internal Control System on Sustainability Information (SCIRS) in place by 2024 in order to better anticipate and prepare for the implementation of the regulation. Within the framework of the taxonomy regulation, EDP has been disclosing the key performance indicators since 2019. There is an individual report available on the following link which provides the 2023 turnover, capital expenditure, and operating costs of its economic activities that are aligned with the EU taxonomy. In March 2023, EDP updated its 2022 Green Finance Framework to reflect the changed scope and the new decarbonisation strategy. Apart from EDP, EDP Finance BV, EDP - Servicios Financieros España, S.A.U. was also a part of the 2023 framework. You can found the new framework on the following here. The framework is aligned with the Green Bond Principles 2021 (GBP), as administered by ICMA, and Green Loan Principles 2023 (GLP), as administered by Loan Market Association (LMA), Asia Pacific Loan Association (APLMA) and Loan Syndications and Trading Association (LSTA). In addition, it is also aligned with the EU taxonomy. The framework is supported by a second-party review from Sustainalytics which you can find here. The proceeds of the issued green finance instruments are used to finance and/or refinance new and/or existing wind and solar assets of EDP Renováveis (EDPR). Eligible assets include wind and solar assets available on the EDP R’s balance sheet, as well as the acquisitions of companies and equity participations in entities on the sector of wind and solar energy production. As of 31 December 2023, EDP sustainable finance instruments (the first was in 2018) represent 58% of our total nominal debt. The objective of EDP is to maintain its sustainable finance model. The Reports on the allocation and impact of Green Finance and sustainability-linked loan include information about the use of resources, projects selection and impacts, and also about the sustainability-linked loans. The information about the green finance is audited by an external party. More details consult the Annex 9 of the Integrated Report 2023.

Includes only stationary emissions. 2 Based on global emission factors of each geography. 3 From 2023 onwards, CO2e emissions associated with distribution grid losses will be calculated on the basis of technical losses, as recommended by the GHG Protocol 4 Based in the suppliers’ emission factors. 5 Methodological review conducted in 2021. The 2020 figures were adjusted based on the new methodology, but the calculations were not audited for that year. The 2020 figure includes 1.4 ktCO2e from category 15 (investments). 6 Emissions that would have occurred if the electricity generated by renewable energy sources were produced by thermal power plants. For each country, it is obtained by multiplying the net renewable production by the emission factor of that country's thermal power plant mix 7 In 2021, the loss indicator was changed to consider the energy input in the grid, and not the output (as until 2020), according to the expectation that the regulator will incorporate this change in the next regulatory period, to align with common practice in other countries (namely Spain and Brazil). 8 Reviewed and harmonized methodology for all geographies, applied since 2015. Excludes Consumption Efficiency Promotion Plan (PPEC) projects. The 2017 values have been revised for consistency with the harmonized savings calculation method. 9 Consider only the category "Use of sold products" of GHG Protocol Corporate Value Chain (Scope 3).

Integrated Annual Report 2023 Financial Statements and Notes 

1\. Economic activity of EDP Group EDP - Energias de Portugal, S.A. (hereinafter referred to as EDP), currently with head office in Lisbon, Avenida 24 de Julho 12 and with its shares listed on the Euronext Lisbon stock exchange, results from the transformation of Electricidade de Portugal, E.P., incorporated in 1976 following the nationalization and consequent merger of the main companies in the electricity sector in Portugal. During 1994, as established by Decree- laws 7/91 and 131/94, the EDP Group (EDP Group or Group) was set up following the split of EDP, which led to a number of directly or indirectly wholly owned subsidiaries of EDP. The Group’s businesses are currently focused on the generation, transmission, distribution and supply of electricity and supply of gas. Additionally, the Group also operates in related areas such as engineering, laboratory tests, professional training, energy services and property management. EDP Group operates essentially in the European (Portugal, Spain, France, Poland, Romania, Italy, Belgium, United Kingdom, Greece, Germany and Netherlands), American (Brazil, Colombia and North America) and Southeast Asia energy sectors. 

2\. Accounting policies a) Basis of presentation 

The accompanying consolidated and company financial statements of EDP - Energias de Portugal, S.A. reflect the results of the company's operations and its subsidiaries (EDP Group or Group) and the Group's interest in its joint ventures and associated companies, for the periods ended on 31 December 2023 and 2022 and EDP S.A.'s Executive Board of Directors approved them on 29 February 2024. The financial statements are presented in thousand Euros, rounded to the nearest thousand. 

In accordance with Regulation (EC) 1606/2002 of the European Council and Parliament, of 19 July 2002, as transposed into Portuguese legislation through Decree-law 35/2005 of 17 February 2005, with changes updated by the Decree-law 158/2009 of 13 July and Decree-law 98/2015 of 2 June, the company's financial statements and the Group's consolidated financial statements are prepared in accordance with International Financial Reporting Standards (IFRS), as endorsed by the European Union (E.U). IFRS comprise accounting standards issued by the International Accounting Standards Board (IASB) as well as interpretations issued by the International Financial Reporting Interpretations Committee (IFRIC) and their predecessor bodies. The EDP Group's consolidated and company financial statements for the years ended 31 December 2023 and 2022 were prepared in accordance with IFRS as adopted by the E.U. and effective since 1 January 2023. 

Taking into account the amendments to IAS 1, effective on 1 January 2023, regarding the disclosure of accounting policies, the Group reviewed the information disclosed in this note and made the changes deemed relevant. 

The accounting policies described in this note have been applied consistently by all the Group companies and in all periods presented in the consolidated and company financial statements. The new standards and interpretations recently issued but not yet effective and that the Group has not yet applied on its consolidated financial statements, are detailed in note 3. 

The financial statements have been prepared on a going concern basis and under the historical cost convention, modified by the application of the fair value accounting to derivative financial instruments, financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income. Assets and liabilities that are hedged under hedge accounting are stated at fair value in respect of the hedged risk. Non-current assets and disposal groups held for sale are stated at the lower of carrying amount and fair value less costs to sell. Liabilities for defined benefit plans are recognised at the present value of the obligation net of plan assets fair value. 

The preparation of financial statements in accordance with IFRS requires the Board of Directors to make judgments, estimates and assumptions that affect the application of the accounting policies and of the reported amounts of assets, liabilities, income and expenses. The estimates and related assumptions are based on historical experience and other factors considered reasonable in accordance with the circumstances, the results of which form the basis for making judgments regarding the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The areas involving the highest degree of judgment or complexity, or for which the assumptions and estimates are considered significant, are disclosed in note 4 - Critical accounting estimates and judgments in preparing the financial statements. 

As at 31 December 2023, following the Strategic Plan Update 2023-2026, the Executive Board of Directors reorganized the business segments in order to be aligned with this new view, with effect from 1 January 2023. Despite of this change in the composition of the segments, EDP Group has not identified any significant changes in key assumptions used in impairment tests performed in the end of 2022, which could indicate that an asset may be impaired. 

b) Basis of consolidation 

The accompanying consolidated financial statements reflect the assets, liabilities and results of EDP, S.A. and its subsidiaries (Group or EDP Group) and the equity and results attributable to the Group, through the investments in associates and jointly controlled entities. 

244 

Integrated Annual Report 2023 Financial Statements and Notes 

Accumulated losses in entities where the Group exercises control are attributed to non-controlling interests in the corresponding proportions held, implying that the Group can recognise negative non-controlling interests. 

On a step acquisition process resulting in the acquisition of control the revaluation of any interest previously held is booked against the income statement when goodwill is calculated. On a partial disposal resulting in loss of control over a subsidiary, any participation retained is revalued at market value on the sale date and the gain or loss resulting from this revaluation is booked against the income statement, as well as any gain or loss resulting from the disposal. 

The consolidated financial statements include the Group's attributable share of total reserves and profits or losses of entities where the Group exercises joint control with other partners (joint ventures) and entities where the Group exercises significant influence (associates), included under the equity method. When the Group’s share of losses exceeds its interest in a joint venture, its carrying amount is reduced to zero and recognition of further losses is discontinued, except to the extent that the Group has a legal or contractual obligation to cover such losses on behalf of that entity. 

Investments in subsidiaries, joint ventures and associates (company level) Investments in subsidiaries, joint ventures and associates not classified as held for sale or not included in a disposal group which is classified as held for sale are accounted for at cost in the company's financial statements, and are subject to periodic impairment tests, whenever indication exists that certain financial investment may be impaired. 

Business combinations Business combinations are accounted for using the acquisition method as at the acquisition date, which is the date on which control is transferred to the Group. Control is the power to govern the financial and operating policies of an entity, obtaining benefits and being exposed to the risks from its activities. In assessing control, the Group takes into consideration potential voting rights that currently are exercisable. The consideration transferred does not include amounts related to the settlement of pre-existing relationships. Such amounts are generally recognised in profit or loss. Costs directly attributable to the acquisition of a business, other than those associated with the issue of debt or equity securities, are booked directly in the consolidated income statement. Any contingent consideration payable is recognised at fair value at the acquisition date. If the contingent consideration is classified as equity, it is not remeasured and settlement is accounted for within equity. Otherwise, subsequent changes to the fair value of the contingent consideration are recognised in profit or loss. 

In accordance with IFRS 3 - Business Combinations, if the initial purchase price allocation of assets and liabilities acquired is identified as provisional, in the subsequent 12 months after the business combination transaction, the legal acquirer should make the final allocation of the purchase price related to the fair value of the assets and liabilities acquired. These adjustments with impact on the amount of goodwill determined and booked in previous periods, originate a restatement of the comparative information, which is reflected on the statement of financial position, with effect from the date of the business combination transaction. The entire positive goodwill resulting from acquisitions is recognised as an asset and recorded at acquisition cost, and is not subject to amortisation. Negative goodwill arising on an acquisition is recognised directly in the income statement in the period when the business combination occurs. 

The recoverable amount of the goodwill is assessed annually, regardless of the existence of any impairment triggers. Impairment losses are recognised in the income statement. 

Goodwill is not adjustable due to changes in the initial estimate of the contingent considerations and the difference is booked in the income statement. The EDP Group recognises the non-controlling interests at fair value including the portion of goodwill attributable to the non-controlling 

interests. 

Business combinations achieved in stages In a business combination achieved in stages, on the date of obtaining control, the excess of the aggregate of (i) the consideration transferred; (ii) the amount of any non-controlling interest recognised in the acquiree; and (iii) the fair value of the previously held equity interest in the acquired business; over the net of amounts of the identifiable assets acquired and liabilities assumed, is recognised as goodwill. 

245 

Integrated Annual Report 2023 Financial Statements and Notes 

On the other hand, if the difference i negative, after evaluating the consideration transferred, of the amount of any non-controlling interest recognised in the acquiree and the fair value of the previously held equity interest in the acquired business, over the net value of the identifiable assets acquired and liabilities assumed, it is recognised in the income statement in the caption Other income. Additionally, the Group reclassifies the deferred amounts in other comprehensive income relating to the previously held equity interest to the income statement or consolidated reserves, according to their nature. 

Purchases of non-controlling interests and dilution In acquisitions (dilutions not resulting in a loss of control) of non-controlling interests, the difference between the fair value of the non-controlling interests acquired and the consideration paid, is accounted against reserves. The acquisitions of non-controlling interests through written put options related with investments in subsidiaries held by non-controlling interests, are recorded as a liability for the fair value of the amount payable, against non-controlling interests. The fair value of the liability is determined based on the contractual price which may be fixed or variable. In case of a variable price, the changes in the liability are recognised against the income statement as well as the effect of the financial discount of the liability (unwinding). 

Acquisition of assets out of the scope of IFRS 3 In order to assess whether an acquisition of an asset or a group of assets is a business, EDP identifies the elements in the acquired entity (inputs, processes and outputs), assesses the capability to create outputs (it should have at a minimum, an input and a substantive process to be assessed as a business) and, finally, assesses the capability of market participants to continuing to create outputs (conducting the activities as a business). In the case of an integrated set of activities that is in an early-stage of development and has not started to generate outputs, EDP considers other factors to determine whether it constitutes a business, such as if: (i) planned principal activities have begun; (ii) employees, intellectual property, and other inputs and processes are present; (iii) a plan to produce outputs is being pursued; and/or (iv) access to customers who will purchase the outputs can be obtained. Generally, an early-stage entity that has employees capable of developing an output will be considered a business. Therefore, in application of the above, EDP concludes that IFRS 3 is not applicable when there are no outputs at the acquisition date due to an early-stage of development, and the acquired process(es) cannot be considered substantive. Thus, the acquisition of an asset or a group of assets that does not fulfil the conditions to be considered a business is classified as an acquisition of a company out of scope of IFRS 3. 

Investments in foreign operations 

The financial statements of the foreign subsidiaries, joint ventures and associates of the Group are prepared using their functional currency, defined as the currency of the primary economic environment in which they operate. In the consolidation process, the assets and liabilities of foreign subsidiaries are translated into Euros at the official exchange rate at the balance sheet date. 

Regarding the investments in foreign operations that are consolidated using the full consolidation method and equity method, the exchange differences between the amount of equity expressed in Euros at the beginning of the period and the amount translated at the official exchange rates at the end of the period, on a consolidated basis, are booked against reserves. 

Foreign currency goodwill arising on the acquisition of these investments is remeasured at the official exchange rate at the balance sheet date directly against reserves. 

The income and expenses of foreign subsidiaries are translated into Euros at the approximate exchange rates at the dates of the transactions. Exchange differences from the translation into Euros of the net profit for the period, arising from the differences between the rates used in the income statement and those prevailing at the balance sheet date are recognised in reserves. On disposal of a foreign subsidiary, the related exchange differences previously recognised in reserves, are accounted for in the income statement. 

Balances and transactions eliminated on consolidation Inter-company balances and transactions, including any unrealised gains and losses on transactions between Group companies, are eliminated in preparing the consolidated financial statements. Unrealised gains and losses arising on transactions with joint ventures and associates are eliminated to the extent of the Group's interest in those entities. 

c) Foreign currency transactions Foreign currency transactions are translated at the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currency are translated into Euros at the exchange rates at the balance sheet date. These exchange differences arising on translation are recognised in the income statement as financial results. 

246 

Integrated Annual Report 2023 Financial Statements and Notes 

Foreign currency non-monetary assets and liabilities accounted for at historical cost are translated using the exchange rates at the dates of the transactions. Foreign currency non-monetary assets and liabilities stated at fair value are translated into Euros at the exchange rates at the dates the fair value was determined. 

d) Derivative financial instruments and hedge accounting 

Derivative financial instruments are recognised on the trade date at fair value. Subsequently, the fair value of derivative financial instruments is remeasured on a regular basis, being the gains or losses on re-measurement recognised directly in the income statement, except for derivatives designated as cash flow hedging instruments. Recognition, in the income statement, of the resulting gains and losses on re-measurement of hedging derivatives depends on the hedge model used. 

The fair value of derivative financial instruments corresponds to their market value, if available, or to quotes indicated by external entities through the use of valuation techniques accepted by the market, which are compared in each date of report to fair values available in common financial information platforms, namely Bloomberg and Reuters. 

Hedge accounting The Group uses financial instruments to hedge interest rate risk, exchange rate risk and price risk resulting from its operational and financing activities. Derivatives not qualified for hedge accounting under IFRS 9 are accounted for as trading instruments. Hedging derivatives are recorded at fair value, being the gains and losses recognised in accordance with the hedge accounting model applied by the Group. Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with any changes in the fair value of the hedged assets and liabilities or group of hedged assets and liabilities that are attributable to the hedged risk. For cross currency interest rate swaps, the currency basis spread is excluded from the hedge designation, but considered as a hedging cost in other comprehensive income, in cost of hedging reserve. When the hedging relationship ceases to comply with the requirements for hedge accounting, the accumulated gains or losses concerning the fair value of the risk being hedged are amortised over the residual period to maturity of the hedged item. Cash flow hedge Changes in the fair value of derivatives qualified as cash flow hedges are recognised in reserves. The cumulative gains or losses recognised in reserves are reclassified to the income statement when the hedged item affects the income statement. When a hedging relation of a future transaction is discontinued, if the transaction is still expected to take place, the changes in the fair value of derivative recognised in reserves remain recognised in reserves until the future hedged transaction occurs. When the future transaction is no longer expected to occur, the cumulative gains or losses recognised in reserves are recorded immediately in the income statement. Net investment hedge The net investment hedge model is applied on a consolidated basis to investments in subsidiaries in foreign currencies. This model allows that the exchange differences recognised in the currency translation reserve to be offset by the foreign exchange differences in foreign currency loans or currency derivatives contracted, recognised in Currency translation reserve - Net investment hedge. For cross currency interest rate swaps, the cross currency basis spread and forward points are not designated into the hedge relationship, but deferred as a hedging cost in other comprehensive income, in Currency translation reserve - Net investment hedge - Cost of hedging, and recognized in profit or loss over the period of the hedge. The ineffective portion of the hedging relationship is recognised in the income statement. The accumulated foreign exchange gains and losses regarding the net investment and the related hedging instrument recognised in equity are transferred to the income statement when the foreign currency subsidiary is sold, as part of the gain or loss resulting from the disposal. Effectiveness The Group performs prospective tests at the inception date and at each balance sheet date, in order to demonstrate its effectiveness, showing that any adjustments to the fair value of the hedged item attributable to the risk being hedged are offset by adjustments to the fair value of the hedging instrument. Any ineffectiveness is recognised in the income statement when it occurs. 

247 

Integrated Annual Report 2023 Financial Statements and Notes 

e) Debtors and Other assets Financial assets 

EDP Group classifies its financial assets, at the initial recognition, based on the business model for managing the financial assets ("business model test") and their contractual cash flow characteristics ("SPPI test"). Financial assets are not reclassified subsequent to their initial recognition. However, if the Company changes its business model for managing financial assets, it will classify newly originated or newly purchased financial assets under the new business model, but will keep the classification of existing assets under the previous businessmodel. 

Purchases and sales of financial assets are recognised on the trade date, which is the date on which the Group commits to purchase or sell these financial assets. 

Financial assets are derecognised when: (i) the Group contractual rights to receive their future cash flows have expired, (ii) the Group has transferred substantially the risks and rewards of ownership, or (iii) although retaining some, but not substantially all the risks and rewards of ownership, the Group has transferred control over the assets. If a factoring transaction results in the transfer of substantially all risks and benefits associated with the assets, the Group proceeds to derecognize the transferred financial assets and recognizes the difference between the carrying amount and the amount received in the income statement (non-recourse factoring). 

Financial assets at amortised cost Financial assets included within this category are initially recognised at fair value and subsequently measured at amortised cost. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains/(losses) together with foreign exchange gains and losses. Impairment losses are presented as separate line item in the statement of profit or loss. Loans and trade receivables are generally held to collect contractual cash flows and are expected to give rise to cash flows representing solely payments of principal and interest, thus they meet the criteria for amortised cost measurement. Financial assets measured at fair value through other comprehensive income (FVOCI) Financial assets included within this category are initially recognised and subsequently measured at fair value, with the changes in the carrying amount booked in other comprehensive income, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses, which are recognised in profit and loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in other comprehensive income is reclassified to profit or loss. 

Financial assets measured at fair value through profit or loss (FVTPL) Financial assets that do not meet the criteria to be classified under the previously referred categories, are classified at fair value through profit or loss. Regardless of the business model assessment, EDP Group can elect to classify a financial asset at fair value through profit or loss if doing so reduces or eliminates a measurement or recognition inconsistency (“accounting mismatch”). 

Impairment losses EDP Group recognises an impairment loss based on the Expected Credit Loss (ECL) model, before the objective evidence of a loss event from past actions. This model is the basis for the recognition of impairment losses on held financial assets that are measured at amortised cost or at fair value through other comprehensive income (which includes cash and cash equivalents, trade receivables, loans and debt securities). The impairment methodology applied depends on whether there has been a significant increase in credit risk since initial recognition. If the credit risk on a financial asset does not increase significantly since its initial recognition, EDP Group measures the loss allowance for that financial asset at an amount equal to 12-month expected credit losses. If the credit risk increases significantly since its initial recognition, EDP Group measures the loss allowance for that financial asset at an amount equal to lifetime expected credit losses. Regardless of the above, a significant increase in credit risk is presumed if there is an objective evidence that the financial asset is impaired, including if there is observable data that comes to the attention of the holder of the asset about the following loss events, among others: significant financial difficulty of the issuer or obligor; restructuring of an amount due to the Group in terms that it would not consider otherwise; a breach of contract, such as a default or delinquency in interest or principal payments; or it becoming probable that the borrower will enter bankruptcy or other financial reorganisation. 

248 

Integrated Annual Report 2023 Financial Statements and Notes 

As soon as the loss event occurs, the impairment allowance would be allocated directly to financial asset affected, that is, the asset’s carrying amount is reduced and the amount of the loss is recognised in profit or loss. If, in a subsequent period, the amount of the impairment loss decreases, the previously recognised impairment loss is reversed in profit or loss, if the decrease can be related objectively to an event occurring after the impairment loss was recognised. 

Trade receivables and contract assets EDP Group applies the simplified approach and records lifetime expected credit losses on all trade receivables and contract assets, including those with a significant financing component. The estimated ECL are calculated based on actual credit loss experience over a period that, per business and type of customers, is considered statistically relevant and representative of the specific characteristics of the underlying credit risk. When applicable, EDP Group estimated the ECL rates separately for corporates and individuals. Considering the particularities of each business, exposures are segmented based on common credit risk characteristics such as credit risk grade, geographic region and/or industry - for corporates; and type of product purchased - for individuals, as applicable. Actual credit loss experience is adjusted by scalar factors to reflect differences between economic conditions during the period over which historical data was collect, current conditions and EDP Group's view of economic conditions over the expected lives of the receivables. Other receivables For receivable assets related to regulatory assets, loans, financial entities and State carried at amortised cost and FVOCI, EDP Group performs an analysis based on the general approach. On making its assessment, the company has to make assumptions about risk of default and expected loss rates, which requires judgement. The inputs used for risk assessment and for calculation of the loss allowances for financial assets includes: (i) credit ratings (as far as available) from external credit rating companies such as Standard and Poors, Moody’s and Fitch; (ii) significant changes in the expected performance and behaviour of the borrower, including changes in the payment status of borrowers in the Group and changes in the operating results of the borrower; (iii) public market data, namely on probabilities of default and loss given default expectations; and (iv) macroeconomic information (such as market interest rates or growth rates). 

Leases – Lessor perspective At the commencement date, EDP Group, as a lessor, classifies each of its lease as either an operating lease or a finance lease. A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to ownership of an underlying asset. Otherwise, the lease is classified as an operating lease. Therefore, at the commencement date, the Group recognises: (i) assets held under a finance lease in its statement of financial position and present them as a receivable at an amount equal to the net investment in the lease. (ii) lease payments from operating leases as income on either a straight‐line basis or another systematic basis (if that basis is more representative of the pattern in which benefit from the use of the underlying asset is diminished). The assets subject to operating leases are presented in its statement of financial position according to the nature of the underlying asset. 

f) Trade payables and other liabilities 

Financial liabilities 

The Group recognises financial liabilities at the issuance date (trade date): (i) initially at fair value less transaction costs; and (ii) subsequently at amortised cost, using the effective interest method. All financial liabilities are booked at amortised cost, with the exception of the financial liabilities hedged at fair value hedge, which are stated at fair value on risk component that is being hedged. 

EDP Group derecognises a financial liability (or a part of a financial liability) from its statement of financial position when, and only when, the obligation specified in the contract is discharged, cancelled or expired. An exchange between an existing borrower and lender of debt instruments with substantially different terms is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. Similarly, a substantial modification of the terms of an existing financial liability, or a part of it, is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The difference between the carrying amount of a financial liability (or part of a financial liability) extinguished or transferred to another party and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognised in profit or loss. 

Lease liabilities Lease liabilities on the commencement date are measured by the Group based on the present value of the future payments of that lease contracts, discounted using EDP Group's incremental borrowing rate for each portfolio of leases identified. The variable lease payments that do not depend in an index or a rate are not included in the measurement of the lease liabilities, nor the right-of- use asset being recognised as cost in the period when they occur. 

249 

Integrated Annual Report 2023 Financial Statements and Notes 

Number of years 

EDP Group determines the lease term as the non‐cancellable period of a lease, together with both: (i) periods covered by an option to extend the lease, if the lessee is reasonably certain to exercise that option; and (ii) periods covered by an option to terminate the lease, if the lessee is reasonably certain not to exercise that option. EDP Group applies the recognition exemption provided by IFRS 16 for the leases which lease term is 12 months or less, or that are for a low-value asset. After the commencement date, the lease liabilities are increased to reflect interest on the liability and reduced to reflect the lease payments made. EDP Group remeasures the lease liabilities, and adjusts the corresponding right-of-use assets, by discounting the revised lease payments, using an unchanged discount rate, if either: i) there is a change in future lease payments resulting from a change in an index or a rate used to determine those payments; or ii) there is a change in the amounts expected to be payable under a residual value guarantee. If there is a lease modification that do not qualifies to be accounted as a separate lease, EDP Group remeasures the lease liabilities and adjusts the corresponding right-of-use assets, by discounting the revised lease payments, using a revised discount rate at the effective date of the modification. 

g) Equity instruments 

Equity instruments issued 

Costs directly attributable to the issuance of equity instruments are recognised in equity, as a deduction to the amount issued. Amounts paid or received relating to sales or acquisitions of equity instruments are recognised in equity, net of transaction costs. 

Distributions related to equity instruments are deducted from equity, as dividends, when declared. Preference shares issued by the Group are considered as an equity instrument when there is no contractual obligation to redeem the shares and dividends are paid at the discretion of the Group. Preference shares issued by subsidiaries, classified as equity instruments and held by third parties, are recognised as non-controlling interests. 

Equity instruments held EDP Group classifies the equity instruments that are held for trading at fair value to profit or loss. For all other equity instruments, management has the ability to make an irrevocable election on initial recognition, on an instrument-by- instrument basis, to present changes in fair value in other comprehensive income. If this election is made, all fair value changes, excluding dividends that are a return on investment, will be included in other comprehensive income. There is no recycling of amounts from other comprehensive income to profit and loss (for example, on sale of an equity investment) being, at that time, transferred to retained earnings. 

h) Property, plant and equipment Property, plant and equipment is stated at acquisition cost less accumulated depreciation and impairment losses. 

Subsequent costs are recognised as Property, plant and equipment only when it is probable that future economic benefits associated with the item will flow to the Group. Repair and maintenance costs are charged in the income statement as incurred, according to the accrual principle. 

The Group carries out impairment tests whenever events or circumstances may indicate that the book value of an asset exceeds its recoverable amount, being any impairment recognised in the income statement. 

Land is not depreciated. Depreciation of tangible assets is calculated on a straight-line basis over their estimated useful lives, as follows: Buildings and other constructions 8 to 50 Plant and machinery: \- Hydroelectric generation 30 to 75 \- Thermoelectric generation 25 to 45 \- Renewable generation 20 to 35 \- Electricity distribution 10 to 40 \- Other plant and machinery 4 to 25 Transport equipment 4 to 25 Office equipment and tools 2 to 16 Other property, plant and equipment 3 to 50 

250 

Integrated Annual Report 2023 Financial Statements and Notes 

The Group reviews the estimate of the useful life of assets whenever a change in the expected economic benefits flowing from the assets occurs as well as when the technical use planned for the assets differs from previous estimates. Changes occurring in the depreciation charge for the year are accounted prospectively. 

Capitalisation of borrowing costs and other directly attributable costs Borrowing costs that are directly attributable to the acquisition or construction of assets are capitalised as part of the cost of these assets. The amount of interest costs eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on those assets. The capitalisation rate corresponds to the weighted average of the borrowing costs applicable to the outstanding borrowings during the period. The capitalisation of borrowing costs begins when expenditure for the assets is being incurred, borrowing costs have been incurred and activities necessary to prepare all or part of the assets for their intended use or sale are in progress. Capitalisation ceases when substantially all the activities necessary to prepare the qualifying assets for their intended use or sale are completed. Other expenses directly attributable to the acquisition and construction of the assets, such as cost of consumed materials and personnel costs, are also capitalised as part of the cost of the assets. 

Investment government grants Investment government grants are initially booked as Trade payables and other liabilities from commercial activities - Non-Current only when there is reasonable certainty that the grant will be received and that the Group will fulfil the grant term conditions. Grants that compensate the Group for expenses incurred are booked in the income statement on a linear basis, on the same period in which the expenses are incurred. Grants that compensate the Group for the acquisition of assets are recognised in the income statement over the related assets useful life. 

Transfers of assets from customers Transfers of assets from customers concession arrangement and out of the scope of IFRIC 12 are related to payments of performance obligations fulfilled over the useful life of the underlying asset. Accordingly, when they are received from the customers, they are booked as liabilities instead of revenue. The assets are recognised by the estimated construction cost and are depreciated over their useful lives. The liabilities are recognised as revenue based on the corresponding useful life of the underlying asset. 

i) Intangible assets The Group's intangible assets are booked at acquisition cost less accumulated amortisation and impairment losses. 

The Group performs impairment tests whenever events or circumstances may indicate that the book value of the asset exceeds its recoverable amount, being any impairment recognised in the income statement. 

Acquisition and development of software The costs of purchasing software and the costs incurred by the Group to implement it are capitalised and amortised on a straight-line basis over the expected useful life of the asset. 

Costs incurred by the Group directly related to the development of software, that are expected to generate economic benefits beyond one year, are recognised as intangible assets. Such costs include employee costs directly associated to the project and are amortised on a straight-line basis over its estimated useful life. 

Software maintenance costs are charged to the income statement when incurred.

Concession rights on distribution of electricity The concession rights on distribution of electricity in Brazil are recorded as intangible assets and amortised on a straight-line basis over the concessions period, not exceeding 30 years. Concession rights to use the public hydric domain Portuguese concession rights to use the public hydric domain are booked as intangible assets and depreciated on a straight-line basis over the concession period, which does not exceed 74 years. EDP Group records as concession rights the financial compensations for the use of public domain assets, whenever these compensations are paid and for all the Group subsidiaries. The accounting policy related to intangible assets assigned to concessions in the scope of IFRIC 12 is described in z), Group concession activities. Concession rights on generation of electricity The concession rights on generation of electricity in Brazil are recorded as intangible assets and amortised on a straight-line basis over the concession period. 

251 

Integrated Annual Report 2023 Financial Statements and Notes 

Industrial property and other rights Industrial property and other rights are amortised on a straight-line basis over the estimated useful life of the assets, not exceeding 6 years. 

j) Right-of-use assets EDP Group presents the information related to lease contracts in the caption Right-of-use assets, in a separate line in the Statement of Financial Position. These assets are accounted for at cost less accumulated depreciation and impairment losses. The cost of these assets comprises the initial costs and the initial measurement of the lease liabilities, deducted from the prepaid amounts and any incentives received. Depreciation of right-of-use assets is calculated on a straight-line basis over their estimated useful lives, considering the lease contract terms. If EDP Group remeasures the lease liability (see f)), the corresponding right-of-use assets are adjusted accordingly. 

k) Investment property The Group classifies as investment property, property held for capital appreciation and/or for rental purposes. Investment property is recognised initially at acquisition or production cost, including directly attributable transaction costs, and is subsequently measured at cost less accumulated depreciation and any impairment losses. Subsequent expenditures on investment property are only added to the cost of the asset when it is probable that additional future economic benefits will arise when compared to initial recognition. Investment property is depreciated on a straight-line basis over the estimated useful life of the assets (between 8 and 50 years).

l) Inventories Inventories are measured at the lower of acquisition cost and net realisable value. The cost of inventories includes purchases, conversion and other costs incurred in bringing the inventories to their present location and condition. The net realisable value is the estimated selling price in the ordinary course of business less the estimated selling costs. The cost of inventories is determined by using the weighted average cost method. 

CO2 Licenses held by the Group for trade purposes are booked as inventories and measured at fair value, at each balance sheet date, against the income statement. 

The Group holds Guarantees of Origin (GOs) as part of its generation and commercialization activities, which are recognised as Inventories and valued at the weighted average cost. The green certificates are considered government support in accordance with IAS 20 and are accounted for under the caption "Revenues and cost of Energy Sales and Services and Other". The unsold certificates are recognised as Inventories in accordance with IAS 2. 

m) Employee benefits Pensions Some EDP Group companies grant post-employment benefits to employees under defined benefit and defined contribution plans, namely pension plans that grant complementary retirement benefits for age and early retirement pensions. Defined benefit plans In Portugal, the defined benefit plan is assured by (i) a closed pension fund managed by an external entity, covering responsibilities with benefits that are complementary to those provided under the Social Security System (namely retirement and early retirement pensions); and (ii) by a complementary specific provision, recognised in the statement of financial position. Benefits are generally determined and assigned through the combination of one or more factors, such as age, years of service and the relevant base retribution (pensionable salary). The responsibilities for early retirement are not covered by the fund’s assets, being adequately provisioned through a specific provision. In Spain, the defined benefit plan is partially covered by insurance policies, and complemented by a specific provision, recognised at the balance sheet. Benefits are generally determined and assigned through the combination of one or more factors, such as age, years of service and the relevant base retribution (pensionable salary). 

252 

Integrated Annual Report 2023 Financial Statements and Notes 

In Brazil, EDP São Paulo and EDP Espírito Santo have defined benefit plans managed by a closed complementary welfare entity, external to EDP Group, covering responsibilities associated with retirement and early retirement pensions, according to factors such as age, years of service and the relevant base retribution. In the pension plans in Brazil, the surplus amount of the assets fund generally can not be reimbursed to the company, since there are very strict rules on the amount that can be recovered, therefore the asset amount to be recognised is greatly reduced. The Group’s pension liability for each plan is calculated by independent experts annually, for each plan, at the balance sheet date, using the projected unit credit method. The discount rate used in the calculation is determined based on market interest rates of high quality corporate bonds denominated in the currency in which the benefits will be paid and that have similar maturity to the related pension liability. Actuarial gains and losses presented in consolidated statement of comprehensive income comprise: (i) the actuarial gains and losses resulting from increases or decreases in the present value of the defined benefit obligation because of changes in actuarial assumptions and experience adjustments; (ii) the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset); and (iii) any change in the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability (asset). The increase in past service costs arising from early retirements (retirements before the normal retirement age) or plan amendments is recognised in the income statement when incurred. The Group recognises as operational results, in the income statement, current and past service costs. Net interest on the net defined benefit liability (asset) is recognised in financial results. The assets of the plan comply with the recognition criteria established by IFRIC 14 - IAS 19 and the minimum funding requirements established by law or by contract. Defined contribution plans Some Group companies in Portugal, Spain and Brazil have defined contribution social benefit plans that complement those granted by the Social Security System, under which they pay an annual contribution to the plans, calculated in accordance with the rules established in each plan. These contributions represent a percentage of the fixed and variable remuneration of the employees included in this plan and are accounted for as cost for the period in which they are due. Other benefits granted - Defined Benefit Type Some EDP Group companies provide medical benefits under which employees and immediate eligible family members have favourable conditions in medical assistance and health care services, namely: \- Concerning EDP Group companies in Portugal, through the provision of medical assistance that is complementary to the one provided under the National Health System, provided using infrastructures owned and managed internally; \- Concerning EDP Group companies in Spain and Brazil, through the share of costs in eligible medical and health expenses, in an external agreed network. In Portugal, the medical benefit and death benefits plan is assured by (i) a closed fund managed by an external entity, created in December 2016, and (ii) a complementary specific provision, recognised in EDP Group company’s statement of financial position. In Spain, the medical care and death subsidy benefits plan is partially covered by insurance policies, and complemented by a specific provision, booked in EDP Group company’s statement of financial position. In Brazil, the liability is being covered by provisions booked in EDP Group company’s statement of financial position. Measurement and recognition of the medical benefits liabilities are similar to the defined benefit pension plans liabilities, explained above. In addition, EDP Group grants other benefits, supporting charges arising from responsibilities for disability benefit’s complements, survival benefits, life insurance, antiquity and retirement benefits, power tariff discounts, among others. These responsibilities are fully covered by a provision. Benefits included in each Plan for Portugal and Brazil are detailed in EDP’s Collective Labor Agreement, published in the Labor Bulletin of 8 October 2014 and in the website of the Plan management entity Enerprev (www.enerprev.com.br), respectively. 

n) Provisions Provisions are recognised when: (i) the Group has a present legal, contractual or constructive obligation; (ii) it is probable that settlement will be required in the future; and (iii) a reliable estimate of the obligation can be made. 

253 

Integrated Annual Report 2023 Financial Statements and Notes 

Provisions for dismantling and decommissioning in electric power plants The Group accounts for provisions for dismantling and decommissioning of assets at the end of the assets’ useful life when there is a legal, contractual or constructive obligation. Therefore, such provisions have been booked for the electric power plants to cover the cost of restoring the location and land to their original condition. The provisions are calculated at the present amount of the expected future liability and are accounted for as part of the cost of the related property, plant and equipment being depreciated on a straight-line basis over the useful life of those assets. Decommissioning and dismantling provisions are remeasured on an annual basis based on the best estimate of the settlement amount. The unwinding of the discount at each balance sheet date is charged to the income statement. 

o) Recognition of revenue from contracts with customers EDP Group recognises revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services, as provided in the 5 steps methodology introduced by IFRS 15, namely: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations; and (v) recognise revenue when (or as) the entity satisfies a performance obligation. Revenue in EDP Group arises from sales of Energy and accesses, Revenue from assets assigned to concessions and Other. Energy and accesses 

Revenue in EDP Group arises essentially from electricity generation, distribution and transmission of electricity and supply of energy (electricity and gas). Additionally, it should be noted that, in energy distribution and supply activities, there is a tariff adjustment mechanism through which gains or losses of a certain year are recognised in the period to which they relate and recovered in the future year’s tariffs – Tariff Adjustments (see w)). 

Revenue related to the sale of energy and access tariffs to energy distribution network is measured at fair value of the consideration received or receivable, net of value added tax, rebates and discounts and after elimination of intra-group sales, being recognised at a point in time when control of the asset is transferred to the customer, generally on delivery of the energy. 

The energy distribution is a regulated activity, which is remunerated through tariffs set by each country Regulatory Body (Entidade Reguladora dos Serviços Energéticos (ERSE) in Portugal, Comisión Nacional de Energía (CNE) in Spain and Agência Nacional de Energia Elétrica (ANEEL) in Brazil). In Portugal and Spain, revenue arises mainly from the sale of access tariffs, as well as from the recovery, from the commercialisation entities, of the costs related to the global management activity of the system. In Brazil, revenue results from the electricity sales to final consumers, in the regulated market, based on the tariffs determined by ANEEL, which are included the use of the distribution and transport system tariff, among other components. The energy supply is carried out in regulated and non-regulated markets. In non-regulated market, revenue is recognised based on commercial agreements. In regulated market, revenue is recognised according to the tariffs determined by each country Regulatory Body. 

Revenue recognition includes two components: (i) energy sales already invoiced, based on actual consumption readings and/or in estimated consumption based on the historical data of each consumer; and (ii) estimates of energy supplied and not yet invoiced (energy into energy meter). Differences between estimated and actual amounts are recorded in subsequent periods. For pluriannual contracts with customers for energy sales including a termination clause determined based on the estimated consumption and contractual set prices, revenue is recognised based on the "Input Method". Under this method, revenue is recognised according to the percentage of the contract execution and the corresponding contractual margin. The margin is reviewed annually, on a contract-by-contract basis, based on the updating of estimated energy supply volumes until the end of the contract. EDP Group also sells products and services as a part of an integrated commercial offer ("bundled"). In a bundled sale arrangement, the Group accounts the sale of each product and/or service separately if they are distinct, that is, if the product or service is separately identifiable in the context of the integrated offer and the customer benefits from it. The consideration paid is allocated between the goods or services separately identifiable based on their relative stand-alone selling prices. The stand-alone selling price is determined based on EDP Group price lists on goods or services sold separately or, if they are not listed, based on the market valuation approach. EDP Group recognises the revenue related with services rendered over time given that the customer simultaneously receives and consumes the benefits provided. In what concerns variable transaction prices, EDP Group only recognises revenue when it is highly probable that there will not be any significant reversal of the recognised revenue, when it becomes certain. 

254 

Integrated Annual Report 2023 Financial Statements and Notes 

EDP Group considers the facts and circumstances when analysing the terms of each contract with customers, applying the requirements that determine the recognition and measurement of revenue in a harmonized manner, when considering contracts with the same characteristics and in similar circumstances. Revenue from assets assigned to concessions In Portugal and Brazil, the distribution and transmission activities are subject to public service concession arrangements, as detailed in z). Contract assets and liabilities EDP Group presents a contract liability if the Group has an obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. EDP Group presents a contract asset if the Group has a right to consideration that is conditional on something other than the passage of time. This is common when the Group has transferred goods or services to a customer usually before invoicing and the payment is due, excluding any amounts presented as a Trade receivables (unconditional rights to consideration). 

Incremental costs of obtaining a contract EDP Group establishes certain contracts with third parties for the promotion (sale) of energy and related services. These third parties act as sales agents and are paid through sales commissions. The Group recognises incremental costs of obtaining contracts with customers as an asset if the entity expects to recover these costs over the respective contracts. The costs incurred by an entity to obtain a contract with a customer are considered as incremental costs whenever it is clear that the entity would not incur these costs if the contract had not been obtained (for example, a sales commission). Therefore, EDP Group understands that the incremental costs to obtain a contract are eligible for capitalisation, accounting for a contract asset under the caption Debtors and other assets of commercial activities - Non-current. This asset shall be recognised in the income statement as amortisation, on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. Considering the analysis carried out on the set of goods and services provided by the EDP Group to which these commissions relate, the useful life allocated to them varies between 6 and 8 years. 

p) Financial results 

Financial results include interest costs on borrowings; interest income on funds invested; the financial expenses (unwinding) related to the discount of the employee benefits liabilities, provisions, institutional partnership in North America and lease liabilities; dividend income; foreign exchange gains and losses; realised gains and losses; changes in fair value of derivative financial instruments related to financing activity classified by the Group, within IFRS 9, as held for trading and consequently measured at fair value through profit or loss; and changes in the fair value of hedged risks, when applicable. 

Interest is recognised in the income statement on an accrual basis. Dividend income is recognised on the date the right to receive is established. 

q) Income tax Income tax recognised in the income statement includes current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case it is also recognised in equity. Deferred taxes arising from the revaluation of assets (debt instruments) measured at fair value through other comprehensive income and cash flow hedge derivatives recognised in equity are recognised in the income statement in the period the results that originated the deferred taxes are recognised. Current tax is the tax expected to be paid on the taxable income for the period, using tax rates enacted at the balance sheet date and any adjustment to tax payable in respect of previous years. Deferred taxes are calculated in accordance with the balance sheet liability method, considering temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax basis, using the tax rates enacted or substantively enacted at the balance sheet date for each jurisdiction and that are expected to be applied when the temporary differences are reversed. Deferred tax liabilities are recognised for all taxable temporary differences except for: goodwill not deductible for tax purposes; differences arising on initial recognition of assets and liabilities that affect neither accounting nor taxable profit; and differences relating to investments in subsidiaries, to the extent that these will probably not be reversed in the future. Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available to absorb deductible temporary differences for taxation purposes. 

255 

Integrated Annual Report 2023 Financial Statements and Notes 

Following the amendments made to IAS 12 - Deferred tax related to assets and liabilities arising from a Single Transaction, effective on 1 January 2023, the EDP Group proceeded with the breakdown of deferred tax assets and deferred tax liabilities related with: i) assets under right of use and lease liabilities; and ii) provisions for dismantling and decommissioning and corresponding tangible fixed assets; where and whenever these amounts are not deductible until the payment date. The compensation between deferred tax assets and liabilities is performed at each subsidiary, and therefore the consolidated financial statements reflect in its assets the total of the deferred tax of subsidiaries that have deferred tax assets and in its liabilities the total of the deferred tax of subsidiaries that have deferred tax liabilities. The Group offsets the deferred tax assets and liabilities if, and only if: (i) the entity has a legally enforceable right to offset current tax assets against current tax liabilities; and (ii) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in future periods in which deferred tax liabilities or assets are expected to be settled or recovered. When accounting for interest and penalties related to income taxes, EDP Group considers whether a particular amount payable or receivable is, in its nature, a taxable income and, if so, applies IAS 12 to this amount. Otherwise, IAS 37 is applied. Regarding the IFRIC 23 related to IAS 12 – Income tax, when there is uncertainty over income tax treatments, EDP Group measures its current or deferred tax asset or liability applying the requirements in IAS 12. Additionally, the Group analyses all the pending litigations or disputes with tax authorities regarding income tax and records the best estimation related to contingencies and litigations whenever necessary. 

r) Earnings per share Basic earnings per share are calculated by dividing the consolidated and the company net profit attributable to the equity holders of EDP, S.A. by the weighted average number of ordinary shares outstanding during the period, excluding the average number of shares held by the Group and by EDP, S.A., respectively. For the diluted earnings per share calculation, the weighted average number of ordinary shares outstanding is adjusted to consider conversion of all dilutive potential ordinary shares, such as convertible debt and stock options granted to employees. The dilution effect corresponds to a decrease in earnings per share resulting from the assumption that the convertible instruments are converted or the options granted are exercised. 

s) Share based payments Stock options remuneration programs enable the Group's employees to acquire parent company shares. The exercise price of the options is calculated based on the listed price of the shares at the grant date. The fair value of the options granted, determined at the grant date, is recognised in the income statement against equity during the vesting period, based on their market value calculated at the grant date. In case the option is exercised, the Group acquires shares in the market to grant them to employees. Shareholders of EDP Brasil structured and implemented a Share based Compensation Policy, which began in June 2016. The referred policy comprises two types of programs to be granted to certain employees (incentive and retention programs), being the eligible beneficiaries and assignment requirements subject to the conditions established. Following the successful completion of the Public Tender Offer auction to EDP Brasil in the third quarter of 2023, the stock options remuneration program has been terminated. 

t) Non-current assets held for sale and discontinued operations Non-current assets or groups of non-current assets held for sale (groups of assets and related liabilities that include at least one non-current asset) are classified as held for sale when their carrying amounts will be recovered mainly through sale, the assets or groups of assets are available for immediate sale and its sale is highly probable. Prior to their classification as held for sale, the measurement of all non-current assets and all assets and liabilities included in a disposal group, is adjusted in accordance with the applicable IFRS standards. Subsequently, these assets or disposal groups are measured at the lowest between their carrying amount and fair value less costs to sell. 

256 

Integrated Annual Report 2023 Financial Statements and Notes 

u) Cash and cash equivalents Cash and cash equivalents include balances with maturity of less than three months from the contract date, including cash and deposits in banks. This caption also includes other short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and specific demand deposits in relation to institutional partnerships that are funds required to be held in escrow sufficient to pay the remaining construction related costs of projects in institutional equity partnerships. On a company basis, EDP S.A. classifies as Cash and cash equivalents the current account balances with Group companies formalized through Cash Pooling Agreements (Group's financial system). 

v) Operating segments The Group presents the operating segments based on internal management information (see note 51). 

w) Tariff adjustments Classification and measurement of regulatory assets, which qualify as financial assets in EDP Group’s financial statements, is analysed based on the business model used in the management of the assets and the characteristics of the contractual cash flows (see e)). In this sense, deviations and tariff deficits exclusively recovered or returned through electricity and gas tariffs, applicable to customers in subsequent periods, are recognised at amortised cost. On the other hand, deviations or deficits that can be recovered, either through electricity rates (receipt of capital and interest) or through sales with recourse to third parties (bilateral contracts or securitization operations) are recognised at fair value through comprehensive income. This classification results from the existing history of sales to third parties and from the management's perspective regarding the existing assets. The sale to third parties results from the Decree-Law 165/2008 of 21 August, which allows regulated companies in Portugal to transfer, in whole or in part, the right to receive tariff deviations or deficits through electricity tariffs. In regulated activities, the regulator establishes, through the tariff adjustment mechanism, the criteria to recognise gains or losses of one period in future periods. The tariff adjustments and deficits accounted for in the EDP Group financial statements represent the difference between the amounts invoiced by the regulated companies (based on the applicable tariffs published by the respective Regulator) and the regulated revenue calculated based on actual costs. The assets or liabilities resulting from the tariff adjustments and deficits are recovered or returned through the electricity and gas tariffs charged to customers in subsequent periods. Following the existing regulatory legislation, the regulated operators of the electric and gas sectors have the unconditional right to recover the tariff adjustments and deficits, therefore EDP Group recognizes under the income statement caption Revenues from energy sales and services and other – Energy and access, the effects resulting from the recognition of tariff adjustments and deficits, against the captions Debtors and other assets from commercial activities and Trade payables and other liabilities from commercial activities. 

x) CO2 Licenses and greenhouse gas emissions 

The Group holds CO2 Licenses in order to deal with gas emissions resulting from its operational activity and Licenses for trading. The CO2 and gas emissions Licenses held for its own use are booked as intangible assets at the acquisition cost. CO2 licenses consumption is recorded in accordance with the weighted average price of the CO2 and gas emissions Licenses held for consumption in that year. 

The Licenses held by the Group for trading purposes are booked under Inventories (see l)). 

y) Statement of Cash Flow The Statement of Cash Flow is presented under the indirect method, by which gross cash flows from operating, financing and investing activities are disclosed. The Group classifies cash flows related to interest and dividends paid as financing activities and interest and dividends received as investing activities. 

z) Group concession activities in the scope of IFRIC 12 EDP Group applies IFRIC 12 to the public-private concession contracts in which the public entity controls or regulates the services rendered through the utilisation of certain infrastructure as well as the price for such services and also controls any significant residual interest in the infrastructure. The infrastructures allocated to concessions are not recognised by the operator as property, plant and equipment or as financial leases, as the operator does not control the assets. These infrastructures are recognised according to one of the following accounting models, depending on the type of remuneration commitment of the operator assumed by the grantor within the terms of the contract: 

257 

Integrated Annual Report 2023 Financial Statements and Notes 

Financial Asset Model This model is applicable when the operator has an unconditional right to receive certain monetary amounts regardless of the level of use of the infrastructure within the concession and results in a financial asset recognition, booked at amortised cost. Intangible Asset Model This model is applicable when the operator, within the concession, is remunerated on the basis of the level of use of the infrastructure (demand risk) and results in an intangible asset recognition. Mixed Model This model is applicable when the concession includes simultaneously guaranteed remuneration and remuneration based on the level of use of the infrastructure within the concession. Intangible assets within concessions are amortised over their respective useful lives during the concession period. The Group carries out impairment tests to the intangible assets within concessions whenever events or circumstances may indicate that the book value of an asset exceeds its recoverable amount, being any impairment recognised in the income statement. Grants received from customers related to assets within concessions are delivered to the Group on a definitive basis, and, therefore, are not reimbursable. These grants are deducted from the value of the assets allocated to each concession. The concession contracts that currently exist in EDP Group are mainly based in the Intangible Asset Model, namely in the electricity special regime production concessions (PRE) in Portugal and in the Mixed Model, namely in the electricity distribution concessions in Portugal and in Brazil. 

aa) Institutional partnerships in North America The Group has entered in several partnerships with institutional investors in North America (EDPR NA), through operating agreements with limited liability companies that apportion the cash flows generated by the wind farms between the investors and the Company and allocates the tax benefits, which include Production Tax Credits (PTCs), Investment Tax Credits (ITC) and accelerated depreciation, largely to the investor. The institutional investors purchase their minority partnership interests for an upfront cash payment with an agreed targeted internal rate of return over the period that the tax credits are generated. This anticipated return is computed based on the total anticipated benefit that the institutional investors will receive and includes the value of PTC’s / ITC's, allocated taxable income or loss and cash distributions received. The control and management of these wind farms are a responsibility of EDP Group and they are fully consolidated in these financial statements. The financial instruments held by the institutional investors issued by the partnerships represent compound financial instruments as they contain characteristics of both financial liabilities and equity. The Group has determined that at the funding dates, the fair values of the original proceeds is equal to the fair values of the liabilities at that time and no value was assigned to the equity component. Subsequently, these liabilities are measured at amortized cost. This liability is reduced by the value of tax benefits provided and cash distributions made to the institutional investors during the contracted period. The value of the tax benefits delivered, primarily accelerated depreciation and ITC are recognised as Income from institutional partnerships on a pro-rata basis over the 5-year recapture period. The value of the PTC's delivered are recorded as generated. This liability is increased by an interest accrual that is based on the outstanding liability balance and the targeted internal rate of return agreed. After the flip date, the institutional investor retains a non-significant interest for the duration of the structure. This non-controlling interest is entitled to distributions ranging from 2.5% to 10% and taxable income allocations ranging from 5% to 10%. EDPR NA has an option to purchase the institutional investor’s residual interest at fair market value during a defined period following the flip date. Post flip non-controlling interests is the portion of equity that is ascribed to the institutional investor in the institutional equity partnership at flip date. This amount is reclassified from the total equity attributable to the Parent to non-controlling interests caption in the period in which the flip date takes place. ab) Disposal of assets under Asset Rotation strategy The Asset rotation strategy allows EDP Group to crystallize the value of a project by selling with loss of control, and reinvesting the proceeds in another projects, targeting greater growth. Typically, the developer retain the role of O&M supplier. The gains on disposals under this strategy are recognised in the caption Other income.

3\. Recent accounting standards and interpretations issued Standards, amendments and interpretations issued effective for the Group The amendments to standards already issued and effective that the Group applied in the preparation of its financial statements, can be analysed as follows: ● IAS 12 (Amended) - Deferred tax related to assets and liabilities arising from a Single Transaction The IASB amended IAS 12, "Income taxes", in order to clarify the recognition of deferred tax on particular transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. The amendments target the recognition of deferred tax in respect of: \- Right-of-use assets and lease liabilities; and \- Provision for dismantling, decommissioning and the corresponding tangible fixed assets. As part of the adoption of these amendments, effective on 1 January 2023, the EDP Group proceeded with the breakdown of deferred tax assets and deferred tax liabilities related with: i) assets under right of use and lease liabilities; and ii) provisions for dismantling and decommissioning and corresponding tangible fixed assets, where and whenever these amounts are not deductible until the payment date. Thus, on 31 December 2023, the impacts of this amendment are disclosed in note 25. ● IFRS 17 - Insurance Contracts (and amendments related to initial application and comparative information) In preparation of the adoption of IFRS 17, effective as of 1 January 2023, the EDP Group carried out an analysis of the contracts of the subsidiary Energia RE - Sociedade Cativa de Resseguro. From the analysis performed, it was concluded that all contracts are eligible, and thus classified, within the Premium Allocation Approach (simplified model) measurement method provided for in IFRS 17. Thus, no material accounting impacts were determined for the EDP Group resulting from the adoption of IFRS 17, in replacement of IFRS 4. The amendments that have been issued and that are already effective and that the Group has applied on its financial statements, with no significant impacts, are the following: ● IAS 1 (Amended) - Disclosure of Accounting Policies; ● IAS 8 (Amended) - Definition of Accounting Estimates; and ● IAS 12 (Amended) - International Tax Reform: Pillar 2 Model Rules (see note 15). Standards, amendments and interpretations issued but not yet effective for the Group The standards, amendments and interpretations issued but not yet effective for the Group (whose effective application date has not yet occurred or, despite their effective dates of application, they have not yet been endorsed by the EU), for which no significant impact is expected, are the following: ● IAS 1 (Amended) - Classification of Liabilities as Current or Non-current; ● IAS 1 (Amended) - Non-current Liabilities with Covenants; ● IFRS 16 (Amended) - Lease liability in a sale and leaseback; ● IAS 21 (Amended) - The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability; and ● IAS 7 and IFRS 7 (Amended) - Supplier Finance Arrangements. 

4\. Critical accounting estimates and judgements in preparing the financial statements IFRS requires the use of judgement and the making of estimates in the decision process regarding certain accounting treatments, with impact in total assets, liabilities, equity, costs and income. The actual effects may differ from these estimates and judgements, namely in relation to the effect of actual costs and income. The main accounting estimates and judgements used in applying the accounting policies are discussed in this note in order to improve the understanding of how its application affects the Group’s reported results and disclosures. A broader description of the accounting policies employed by the Group is disclosed in note 2 - Accounting policies. Considering that in many cases there are alternatives to the accounting treatment adopted by EDP Group, the reported results could differ if a different treatment was chosen. The Executive Board of Directors believes that the choices made are appropriate and that the financial statements present fairly the Group operations in all material respects.

Integrated Annual Report 2023 Financial Statements and Notes 

Financial asset related with infrastructure concession contracts in Portugal The caption “Amounts receivable from concessions - IFRIC 12”, refers to the financial assets receivable by EDP Group companies that operate infrastructures under concession contracts, and arises from the unconditional right to receive this amount regardless of the utilisation level of the infrastructures covered by the concession. In these companies is included E-Redes – Distribuição de Eletricidade, S.A. as the National Distribution Network (RND) concessionaire, which comprises the medium and high voltage network (MT and HT), and low voltage distribution networks (LT), being these concessions exercised exclusively through public service concession contracts. The RND’s operation, which is part of the HT and MT, is carried out through a public service concessions’ attribution, by the Portuguese State. On the other hand, the right to distribute low voltage electricity is attributed to the Portuguese mainland municipalities. The legislation that establishes the basis of each concession sets up that the ownership or possession of the goods assigned to these concessions revert to the concessionaires at the end of their respective concessions. They also establish that in return for the assets returned to grantors, whether State or municipalities, compensation corresponding to the assets’ book value assigned to the concession, net of amortisations, financial contributions and non-refundable subsidies will be paid. Therefore, the assets’ estimated residual value at the end of each concession constitutes a financial asset, and the remaining fair value component of the concession assets is an intangible asset to be amortised over its useful life. Hence, the end date of each concession is one of the main assumptions to determine the amount of the financial and intangible assets. In May 2017 Law 31/2017 was approved, which lays down the principles and general rules concerning the organisation of public tendering procedures for the awarding, by contract, of the municipal LT concessions’ operation in the Portuguese mainland. This Law foresee the simultaneous launch, in 2019, of public tender procedures for all municipalities that do not opt for direct management of the electricity distribution activity. However, the new Decree-Law 15/22, of January 2022, determined the automatic extension, without the need for further terms, of the current concession contracts for electricity distribution networks in BT, including those that had already reached their term, until the effective entry into operation of a new contractor, following the tenders for the attribution of BT concessions that will be held in the future. Decree 397/2023, of 28 November 2023, defined the standard pieces of the public tender procedure for the allocation of low-voltage electricity distribution concessions, namely the procedure program, the standard terms of reference, and the standard concession contract. The initiative to initiate the tender processes is transferred to the municipalities, and there is no date provided in the legislation for their execution or additional involvement by the Government. Although the published Decree does not provide information regarding the delimitation of areas for the tenders, the Government issued a statement on 29 November 2023, indicating that in April 2023, the National Association of Portuguese Municipalities expressed a preference for a territorial area covering the entire mainland territory, "having this option been integrated into the procedure", according with the aforementioned statement. In this context, at this date it is not yet possible to predict the end date of the low voltage concession contracts currently in force, so an annual extension of contracts that have already reached the originally planned end date is assumed. Thus, with reference to 31 December 2023, the financial asset and the intangible asset related to the concessions whose contracts have not yet ended were determined based on the respective expiry dates and, for the remaining concessions, the financial asset and the intangible asset are determined assuming the validity of the contracts until 31 December of the year following the year in question. Measurement criteria of the concession financial receivables under IFRIC 12 in Brazil In 2012, the Provisional Measure 579/12 was published in Brazil, meanwhile converted into Law 12.783/13, which determines that the amount of the indemnisation payable to the distribution companies regarding the assets not amortised or depreciated at the end of each concession, should be determined based in the methodology of the Value of Replacement as New (VNR). The indemnisation amount variation is booked against Revenues from energy sales and services and other. This amount corresponds to the difference between the residual value determined based on the value of replacement as new and the residual value determined based on the historical cost. ANEEL reviews the VNR, through the valuation report of the Regulatory Remuneration Base, every three years for EDP Espírito Santo and every four years for EDP São Paulo, as established in the concession contracts. Within these periods the distribution companies use their best estimate for the VNR. The use of different assumptions could result in different values of financial assets, with the consequent impact in the Statement of Financial Position (see note 27). Impairment of long term assets and Goodwill Impairment tests are performed whenever there is a trigger that the recoverable amount of property, plant and equipment and intangible assets is less than the corresponding net book value of the assets. 

260 

Integrated Annual Report 2023 Financial Statements and Notes 

On an annual basis, the Group reviews the assumptions used to assess the existence of impairment in goodwill resulting from acquisitions of shares in subsidiaries. The assumptions used are sensitive to changes in macroeconomic indicators and business assumptions used by management. The investments in subsidiaries, on a company basis, and in associates are reviewed when circumstances indicate the existence of impairment. Considering the uncertainties regarding the recoverable amount of property, plant and equipment, intangible assets and goodwill as they are based on the best information available, changes in the assumptions could result in changes on the determination of the amount of impairment and, consequently, in results (see notes 12 and 20). Measurement of the fair value of financial instruments Fair values are based on listed market prices, if available. Otherwise, fair value is determined either by the price of similar recent transactions under market conditions, or determined by external entities, or based on valuation methodologies, supported by discounting future cash flows techniques, considering market conditions, time value, yield curves and volatility factors. These methodologies may require the use of assumptions or judgements in determining fair values. Consequently, the use of different methodologies and different assumptions or judgements in applying a particular model, could generate different financial results from those reported. Classification of financial instruments Financial instruments’ classification as debt or equity requires judgement in the interpretation of contractual clauses and in the evaluation of the existence of a contractual obligation to deliver cash or other financial assets. Review of the useful life of the assets The Group reviews annually the reasonability of the useful lives attributed to the assets, that are the base to the corresponding depreciation rates. When applicable, the Group changes, prospectively, the asset's useful life and, subsequently, the depreciation rates of the period based on such review. Useful lives of generation assets - Hydro independent generator in Brazil The hydro generation assets in Brazil for independent generators are amortised during their estimated useful lives, considering the existing facts and circumstances at the date of preparation of the financial statements. This includes, among other issues, EDP's best expectations of the useful lives of such assets, which are consistent with the useful lives defined by ANEEL, the respective contractual residual indemnification values at the end of each concession period, as well as related technical and legal opinions. The remaining period of amortisation and the indemnification values at the end of the concessions may be influenced by changes in the regulatory legal framework in Brazil (see note 17). Lease contracts The Group recognises right-of-use assets and lease liabilities, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Group assesses whether: i) the contract involves the use of an identified asset; ii) it has the right to obtain substantially all of the economic benefits from the use of the asset throughout the period of use; and iii) it has the right to direct the use of the asset. EDP Group uses judgement on its assessment, namely concerning the termination and extension contract options and the determination of the incremental borrowing rate to be applied for each portfolio of leases identified (see notes 18 and 40). Tariff adjustments Portugal Tariff adjustments in Portugal represent the difference between costs and income of the National Electricity, estimated at the beginning of each period for purposes of calculating the tariff, and the actual costs and income of the System established at the end of each period. The tariff adjustments assets or liabilities are recovered or returned through electricity and gas tariffs to customers in subsequent periods. 

261 

Integrated Annual Report 2023 Financial Statements and Notes 

Decree-Law 237-B/2006 of 19 December, and Decree-Law 165/2008 of 21 August, recognised an unconditional right of the operators of the electricity sector to recover the tariff adjustments and related interest expenses, notwithstanding the form of the future payment or situations of insolvency and cessation of operations. Additionally, the legislation allows the transfer to third parties of the right to receive tariff adjustments. Therefore, under this legislation, regulated companies may provide to third parties, in whole or in part, the right to receive the tariff adjustments through the electricity tariffs. In accordance with the accounting policy in force, the EDP Group books under the caption Revenues from energy sales and services and other - Electricity and network access, the effects of the recognition of tariff adjustments in the electricity sector, against Debtors and other assets from commercial activities and Trade payables and other liabilities from commercial activities. Brazil On 25 November 2014, ANEEL made addendums to the concession contracts with electric distribution companies to reduce significant uncertainties regarding to the recognition and realization of regulatory assets/liabilities that existed since 2010, when the IFRS were adopted in Brazil. As a consequence, the CPC ("Comitê de Pronunciamentos Contábeis") issued on 28 November 2014, the OCPC 08 (Recognition of Certain Assets and Liabilities in Accounting and Financial Reports of Electric Distribution) which determines how to treat these regulatory assets/liabilities in the financial statements. Therefore, on 10 December 2014, EDP Brasil signed the Fourth and Fifth Addendum to the Concession Agreement, where it was established that, in the case of concession termination, the outstanding balances of any failure of payment or reimbursement by the tariff (assets and liabilities), will be considered on the indemnity calculation, based on the regulator pre-established regulations. EDP Group considers, based on the issued legislation (Portugal and Brazil), that the requirements for the recognition of tariff deficits as receivables and payables against the income statement of the period have been satisfied (see notes 7, 27 and 39). Revenue recognition Energy sales revenue is recognised when the monthly energy invoices are issued, based on actual meter readings or estimated consumption based on the historical data of each consumer. Revenue relating to energy to be invoiced, regarding consumption up to the balance sheet date but not measured, is booked based on estimates that take into consideration factors such as consumption in prior periods and analysis relating to the energy balance of the operations. The use of different estimates and assumptions could affect the Group’s revenue and, consequently, its reported results (see note 7). Income taxes The Group is subject to income taxes in several jurisdictions. Certain interpretations and assumptions are required in determining the global amount of income tax. There are several transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. It is the Group's understanding that, in general, the tax treatment follows the accounting treatment, and therefore, no significant tax adjustments have been made to the accounting records arising from the implementation of the new standards. Different interpretations and assumptions could result in a different level of income taxes, current and deferred, recognised in the period (see note 15). Pensions and other employee benefits Determining pension and other employee benefits liabilities requires the use of assumptions, including actuarial projections, estimated rates of return on investments, discount rates and pension and salary growth and other factors that can impact the cost and liability of pension plans, medical plans and other benefits. Changes in the assumptions could materially affect the amounts determined (see note 36). Provisions for dismantling and decommissioning of power generation units EDP considers to exist legal, contractual or constructive obligations to dismantle and decommission property, plant and equipment assets allocated to electricity generation operations. The Group records provisions in accordance with existing obligations to cover the present value of the estimated cost to restore the locations and land where the electricity generation units are located. EDP Group provisions include the calculation of the present value of the expected future liabilities. The use of different assumptions and judgement from those referred could lead to different financial results and depreciations than those considered (see note 37). Entities included in the consolidation perimeter In order to determine which entities must be included in the consolidation perimeter, EDP Group evaluates whether it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee ("de facto" control). This evaluation requires the use of judgement and assumptions. 

262 

Integrated Annual Report 2023 Financial Statements and Notes 

Other assumptions and judgements could lead to a different consolidation perimeter of the Group, with direct impact on the consolidated financial statements (see note 6). Business combination Under IFRS 3 (Business Combination) in a business combination, the acquirer shall recognise and measure in the consolidated financial statements the assets acquired and liabilities assumed at fair value at the acquisition date. The difference between the purchase price and the fair value of the assets and liabilities acquired leads to the recognition of goodwill or a gain from a purchase at a low price (bargain purchase). The fair value determination of the assets acquired and liabilities assumed is carried out internally or by independent external evaluators, using the discounted cash flows method, using the replacement cost or other fair value determination techniques, which rely on the use of assumptions including macroeconomic indicators such as inflation rates, interest rates, exchange rates, discount rates, sale and purchase prices of energy, cost of raw materials, production estimates and business projections. The determination of the fair value and, consequently, of goodwill or gain from a bargain purchase is subject to numerous assumptions and judgments and therefore changes could result in different impacts on results. Fair value measurement of contingent consideration Contingent consideration from a business combination or a sale of a financial investment is measured at fair value at the acquisition date as part of the business combination or at the date of the sale in the event of a sale of a financial investment. This contingent consideration is subsequently remeasured at fair value at each report date. Fair value is based on discounted cash flows. The main assumptions consider the probability of achieving each objective and the discount factor, corresponding to the best estimates of management at each report date. Changes in assumptions could have significant impact on the values of contingent assets and liabilities recognised in the financial statements (see notes 28 and 40). Acquisition of assets out of the scope of IFRS 3 In order to assess whether an acquisition of an asset or a group of assets is a business, the Group identifies the elements in the acquired entity (inputs, processes and outputs), assesses the capability to create outputs and, finally, assesses the capability of market participants to continuing to create outputs. The Group concludes that IFRS 3 is not applicable when there are no outputs at the acquisition date due to an early-stage of development, and the acquired process(es) cannot be considered substantive. Thus, the acquisition of an asset or a group of assets that does not fulfill the conditions to be considered a business is classified as an acquisition of a company out of scope of IFRS 3. Contractual stability compensation - CMEC The approval in 2004 of the Decree-Law 240/2004, of 27 December, determined the early Power Purchase Agreements (PPA) extinction, and the adoption of a contractual stability compensation (CMEC), which EDP Produção entered into after signing the Contractual stability on 27 January 2005, approved by the competent Government member (Order 4672/2005, of 4 March). This mechanism includes three types of compensation: initial compensation, annual adjustment (or revisibility) and final adjustment. The last two types of compensation are relevant for this purpose. i) Contractual stability compensation – Annual revisibility mechanism During period I (2007/2017) of the contractual stability compensation mechanism, there was a correction on an annual basis, resulting from positive or negative deviations between the estimates made for the initial stability compensation calculation and actual amounts arising from an efficient performance, using the "Valorágua" model, as established in the Decree-Law 240/2004. In 2014, Dispatch 4694/2014 of 1 April 2014, amended the procedures to be followed in the calculation of the annual revisibility regarding the consideration of revenues obtained in the system services market (secondary regulation band) by the power plants covered by the CMEC mechanism. Revisibility amounts for the years 2007 to 2014 were determined and approved by the Member of the Government responsible for the energy sector, and were contested by EDP Produção: a) As regards the approval of the 2011 and 2012 revisibilities, the fact that it did not consider the costs incurred with the social tariff in the calculation of the revisibilities; and b) As regards the approval of the 2014 revisibility, the fact that it did not take into account in the calculation of the revisibility the costs incurred with the social tariff and CESE. Regarding the revisibility to the years 2011 and 2012, the Administrative Court dismissed, in different occasions, the special administrative actions brought by EDP Produção, not recognizing these costs with the financing of the Social Tariff for the determination of the amount of the annual adjustment of CMEC relating to 2011 and 2012. EDP Produção, not agreeing with these decisions, filed an Appeal for both years. 

263 

Integrated Annual Report 2023 Financial Statements and Notes 

The annual revisibility of 2015 was approved by the Government member responsible for the energy sector in 20 October 2020 in the amount of 62.7 million Euros, after deducting an amount of 72.9 million Euros related to the alleged overcompensation of CMEC, due to their participation in the ancillary services market, in the period between 2009 and the first quarter of 2014 (see section Ancillary Services). EDP Produção challenged the order for ratifying the annual revisibility for the year 2015 on 19 January 2021, as it did not agree with the assumption of overcompensation within the scope of its performance in the system services market, between 2009 and 2014 and, consequently, do not agree with the deduction of the underlying value (72.9 million Euros) in that revisibility. It should also be noted that EDP Produção has already contested the imposition of a fine by the Competition Authority on matters of the same scope. The challenge also covered the non- consideration of the Social Tariff and CESE amounts paid by the centrals operating under the CMEC regime and also the non-approval of the annual revisibilities from 2016 to 2017, which still await the respective approval by the Government member responsible for the area of energy. ii) Contractual stability compensation – Final Adjustment The CMEC’s Final Adjustment is calculated in accordance with number 7 of article 3rd and Annex IV of Decree-Law 240/2004, of 27 December. The State budget for 2017 (Law 42/2016 of 28 December) determined, in its article 170, that the final adjustment amount is determined and based on a study prepared and presented by ERSE. This entity had the technical support of EDP Produção and REN (Work Team), legally enforced. Accordingly, the technical group EDP/REN has presented to ERSE its report on the CMEC final adjustment calculation, which was achieved by strictly following the calculation methodology described in Decree-Law 240/2004, of 27 December. This calculation, performed by the technical group EDP/REN was presented to ERSE and comes to a range of amounts between 256.5 and 271 million Euros. At the end of September 2017, ERSE has also presented to the Government its report on the calculation of the CMEC final adjustment, reaching an amount of 154 million Euros, which was provisionally considered in the document of Tariffs and Prices for 2018. In the Financial statements as at 31 December 2017, EDP Group has included its best estimate of the CMEC final adjustment, by recognising an asset in the amount of 256.5 million Euros against deferred income, based on the methodology established for this purpose in Decrew-Law 240/2004, of 27 December, and in the legal opinions obtained in the meantime on this understanding. On 3 May 2018, EDP was notified (through a DGEG’s letter from 25 April 2018) that the CMEC final adjustment had been officially approved, according to ERSE’s proposal, in the amount of 154 million Euros. EDP reflected this reality in its financial statements as of 31 December 2018, recognising a provision by the difference in the final adjustment amounts already recognised in the Group's revenues. On 31 December 2023 EDP maintains the provision in its accounts (see note 37). Considering that the administrative act contained in the Dispatch of approval of the SSE of 25 April 2018 lacks technical, economic and legal basis, and that, in particular, it does not apply the calculation methodology contained in Decree-Law 240/2004, of 27 December, and which would lead to the determination of an amount close to the one determined by the technical group, on 3 September 2018, EDP Produção has legally contested it. "Clawback" - Portuguese regulatory mechanism to ensure the competitive balance in the wholesale electricity market, in particular Iberian Following some tax changes occurred in Spain, which affected electricity generators operating in this country, Decree-Law 74/2013, of 4 June, was approved in Portugal, which aimed to rebalance the competition between electricity generators operating in Portugal and other players operating in Europe. Pursuant to relate diploma and its regulations, in order to restore such balance, the power plants operating on a market regime situated in Portugal, which were not covered by the PPA or CMEC regime, should pay to the System an amount per MWh produced. The amount payable should consider, on one hand, an estimate of the impact that the off-market events in the European Union (such as the above-mentioned tax changes in Spain) would have in pool prices, and on the other hand, the existence of national extra-market events that affect the competitiveness of electricity generators operating in Portuguese territory. Consequently, a net competition advantage would allegedly arise to generators operating in Portugal. Under this mechanism regulation – commonly known as clawback – Social tariff and CESE were determined by Dispatch 11566-A/2015, of 3 October, as off-market events that should be considered as competitive disadvantages of generators operating in Portugal. Dispatch 7557-A/2017, of 25 August, superseded Dispatch 11566-A/2015 (which defined the variables for the computation formula of the amount to be paid by each of the power-generating plants under Decree-Law 74/2013, of 4 June, for each injected MWh). It states that ERSE, after consulting DGEG, should present proposals for a new definition of the variables, as well as reference terms for the new study. 

264 

Integrated Annual Report 2023 Financial Statements and Notes 

Subsequently, the Dispatch 9371/2017, of 24 October, partially nulled the Dispatch 11566-A/2015, in relation to the decisions presented under its numbers 11 and 12 (the deduction of social tariff and CESE costs in the unit price). ERSE was asked to consider in 2018 UGS tariff, the recovery, in benefit of the consumers, of the amounts allegedly unproperly included in previous years’ tariffs (2016 and 2017). Dispatch 9955/2017, of 17 November, defines a new amount for the estimate of the off-market events’ impact in EU, which is -4.75 €/MWh, with retroactive effects as at August 24. Following these Dispatches, the document of prices and tariffs for 2018 has included a clawback amount of around 90 million Euros to be returned to tariffs, which includes power plants operating under CMEC and estimated generation. Based on its interpretation of the Law, as well as on legal opinions obtained, EDP Produção considers that the Decree-Law 74/2013, of 4 of June, aims to re-establish a situation of competition balance between generators operating in Portugal and their peers operating in other European countries, which means to consider as off-market events all the taxes and contributions that fall only over generators located outside of Portugal (particularly in Spain), as well as all the taxes and contributions that fall only over generators located in Portugal. Consequently, in the EDP Produção’s understanding, supported by legal opinions, Dispatch 9371/2017 and 9955/2017 have completely distorted the clawback mechanism, having filed its legal action in January 2018. In the Financial statements as at 31 December 2018, EDP Group has included the clawback amount as calculated by EDP Produção, regarding the legislation in place in each period, namely Decree-Law 74/2013, of 4 of June, Order 225/2015, Ordinance 9371/2017 and Dispatch 9955/2017. It is important to notice that this mechanism is not applicable to power plants in 2018 still operating under CMEC regime. However, this situation was subsequently changed and disputed by EDP Produção, as mentioned below. On 5 October 2018, the Spanish legislature, by the sixth and seventh additional lines on Article 21 of Royal Decree-Law 15/2018, suspended the 7% tax on electricity generation approved in 2012 for a period of six months, from the beginning of October 2018 to the end of March 2019. This tax suspension corresponds to the suspension of the off-market event verified within the European Union, which is considered in the clawback calculation. Following the temporary suspension of the tax on electricity generation in Spain: \- Order 895/2019 of 23 January, establishing the suspension of the "Clawback" was approved for a period of 6 months as from 1 October 2018; \- The Tariff and Price Document for 2019, published on 17 December 2018, estimates a Clawback value of € 4.18/MWh, to be applied after the end of the suspension period (more specifically from 6 April 2019); \- ERSE informed EDP Produção that any clawback invoicing relating to the referred suspension period should be deleted or cancelled; and \- The State Budget Law for 2019 provided that "the Government shall, until the end of the first quarter of 2019, review the regulatory mechanism designed to ensure the balance of competition in the wholesale electricity market in Portugal, provided for under DL 74/2013, of 4 June, adapting it to the new rules of the Iberian Electricity Market, with the aim of creating harmonized regulatory mechanisms that reinforce competition and protect consumers". On 1 April 2019, the suspension of the tax on the generation of electric energy in Spain was terminated, and it became effective again. From that moment, the "clawback" invoiced to EDP Produção was resumed, based on a value of 4.75€/MWh. On 9 August 2019, Decree-Law 104/2019 was published, which makes the first amendment to Decree-Law 74/2013, of 4 June, by changing the scope of the clawback mechanism. Previously, “electricity producers under the ordinary regime and other producers not covered by the guaranteed remuneration regime" were subject to clawback. With the publication of this diploma, the CMEC centrals are now included in the scope of the clawback. Considering that this scope contradicts the Decree Law 240/2004, of 27 of December, EDP Produção proceeded to its challenge. The same Decree-Law introduced the possibility to define CIT (corporate income tax) – advanced payment, and on 26 September 2019 was published the Order 8521/2019, which set the amounts of advanced payment related to the clawback mechanism at 2.71€/MWh for coal-fired power plants and 4.18€/MWh for other power plants. In the Tariff and Price Document for 2020, published on 16 December 2019, ERSE considered the unit values defined in Dispatch 8521/2019, correcting only the value applicable to coal to 1.23 €/MWh, due to the increase in the ISP tax percentage and CO2 addition planned for 2020. EDP Produção presented on 10 March of 2020 an action seeking a declaration of nullity or annulment of that administrative act by ERSE. On 27 December 2019, Dispatch 12424-A/2019 was published, which identifies as national extra-market events to be considered in the Study to be prepared by ERSE until April 2020 (with reference to 2019) under the Clawback mechanism, the taxation of petroleum and energy products used in the generation of electricity (ISP), CESE and the Social Electricity Tariff.

Integrated Annual Report 2023 Financial Statements and Notes 

On 30 June 2020, Dispatch 6740/2020 was published by the Secretary State of Energy (SEAE) which establishes the CIT (corporate income tax) – advanced payment to be applied in 2020 to electric power producers covered by the "Clawback" mechanism. The value of CIT – advanced payment for the year 2020 is set at € 2.24/MWh for plants that are not subject to extra market internal events, that is, only to some renewable energy producers in the market with the exception of the power generation centers included in the scope of internal extra-market events identified. On 22 October 2020, Dispatch 10177/2020, issued by the SEAE Office, was published, which determines the final compensation of the “Clawback” for the year 2019, considering the ISP regime as the only internal off-market event within the National Electrical System (SEN), thus determining a value of € 2.24/MWh for hydro, gas and PRE on the market and 0.68€/MWh for coal power plants. This determination is not consistent with that contained in Dispatch 12424-A/2019, of 27 December, which identifies ISP, CESE and Social Tariff as internal off-market events for 2019. EDP Produção challenged Order 10177/2020 on 22 January 2021. On 25 June 2021, the Spanish legislator, within the scope for the adoption of urgent measures regarding energy taxation due to the high prices verified in the MIBEL, published the Royal Decree-Law 12/2021, which, among others, proceeds the suspension of the 7% tax on the generation of electricity, approved in 2012, for a period between 1 July and 30 September 2021 (3 months), and with effects on the determination of the “Clawback”. Following Royal Decree-Law 17/2021, the Spanish legislator has once again suspended the 7% tax on electricity generation for another 3 months, between 1 October and 31 December 2021. Following the temporary suspension of the tax on the generation of electricity in Spain, Dispatch 6398-A/2021, of 29 June, was published, which established the suspension of the “Clawback” in the period between 1 July 2021 and 30 September 2021, and Order 9975/2021, of 14 October, which determines the suspension of this mechanism between 1 October and 31 December 2021. On 14 October 2021, Order 9974/2021, of the SEAE Office, was published, which determines the final compensation of the "Clawback" for the year 2020, considering as the only extra-market event within the National Electric System the regime of ISP (noting that it is consistent with the Dispatch that approved the final value for the year 2019), resulting in the following “Clawback” values: 3.64€/MWh for hydro plants and Special Regime generation (PRE) in the market; 3.42€/MWh for CCGTs; and 2.16€/MWh for coal plants. This determination is not coherent with the goals and rationale underlying the “Clawback” mechanism, as it does not admit the Social Tariff and CESE as internal extramarket events. EDP Produção challenged Order 9974/2021 on 14 January 2022. The Spanish legislator suspended again the 7% tax on electricity generation for another 6 months, through Royal Decree-Ley 29/2021, of 21 December (for the period between 1 January and 31 March 2022) and Royal Decree-Ley 6/2022, of 29 March (for the period between 1 April and 30 June 2022). Following this temporary suspension of the tax on electricity generation in Spain, Order 1322/2022 of 1 February was published, which established the suspension of the “Clawback” between 1 January and 31 March 2022, and Order 6287/2022, of 19 May, which extended this suspension until 30 June 2022. More recently, the Spanish legislator, due to the maintenance of high prices in the MIBEL resulting, above all, from the Russia-Ukraine conflict, resumed the suspension of the 7% tax on electricity generation until the end of 2022, through the Royal Decree-Ley 11/2022, of 25 June, and Order 9838/2022, of 9 August, determined the suspension of the “Clawback” for the period between 1 July and 31 December 2022 in Portugal. In the year 2023 the tax on generation in Spain is suspended, in accordance with Royal Decree-Ley 20/2022 of 27 December. In Portugal, Order 5748/2023, of 22 May, of the Secretary of State for Energy and Climate, also suspended the “Clawback” during the year 2023. On 25 January 2024, Dispatch 976/2024 determined the final compensation for the "Clawback" related to the year 2021, based on scenario A of the ERSE study from April 2022. This scenario considers the ISP regime as the only internal off-market event to the National Electricity System (SEN), thus establishing a value of 7.10 €/MWh for hydroelectric, wind, and solar power plants in the market, and a null value for CCGT, as they did not exceed the exemption threshold of 2000 hours of use of their installed capacity. However, in addition to this value not considering all internal off-market events (CESE, Social Tariff, and G-Charge), the Dispatch is not in line with the advance payments applied in 2021, resulting from Dispatch 6740/2020, which set a null value for power plants that support the Social Tariff and CESE. The cost for the EDP Group associated with the publication of Dispatch 976/2024 has already been recorded in the accounts in 2021 and 2022. Social Tariff Scheme EDP Group filed a request to the European Commission whether the compliance of the Social Tariff funding mechanism, which is fully supported by ordinary regime generators, complies with the rules and principles of European Union law. The European Commission has recognized the discriminatory nature of the social tariff funding mechanism in Portugal and has informed that it will maintain surveillance over its evolution, particularly in the context of tariff revisions for 2023.

On 17 November 2023, Decree-Law 104/2023 was published in the Official Gazette, amending the financing model of the social tariff established in Decree-Law 15/2022. The amendment includes, in addition to the producers, the suppliers and other agents in the consumption function as the financing entities for the costs of the social tariff. The allocation of the associated costs is carried out in two phases, with the allocation being made first by activity, followed by the agents within each activity. On 9 January 2024, Directive 1/2024 approved the allocation of costs for the social tariff from 1 January to 17 November 2023, as well as the adjustments from 2018 to 2022. Regarding the allocation of costs from 18 November to 31 December 2023, and for the year 2024, ERSE published a public consultation on 23 January 2024, which also considers the operational procedures of the new social tariff financing mechanism. From 2011 to 2022, EDP has incurred a cost of over 530 million Euros due to the social tariff. Regarding 2023, the EDP Group will have to pay around 77 million Euros. Ancillary Services i) Secondary regulation band service On 3 September 2018 the Autoridade da Concorrência (AdC) adopted a Note of Illegality, under which it intended to attribute to EDP Produção a behaviour of abuse of a dominant position in the secondary regulation band service. AdC claimed that EDP Produção restricted the offer of a segment of the Electricity System (the secondary regulation band or teleregulation service) between January 2009 and December 2013, limiting the capacity offer of its plants under CMEC regime to benefit market power plants, in order to benefit twice, to the detriment of consumers. On 28 November 2018, EDP Produção exercised its right to be heard and to defend itself in relation to the wrongful act was imputed and the sanctions it could incur, that is, it responded to the Note of Illegality. On 18 September 2019, AdC informed EDP Produção of its decision to condemn, imposing a fine of 48 million Euros, for alleged abuse of dominant position in the secondary regulation band market in mainland Portugal between January 2009 and December 2013. According to AdC, EDP Produção would have manipulated its offer of tele-regulation service or secondary regulation band, limiting the capacity offer of its CMEC power plants to offer it through its market power plants, benefiting in two ways: \- Highest compensation paid to CMEC plants (annual revisability), as their lower participation in the provision of secondary regulation band service would be below what would be expected (according to competitive market criteria); and \- The increase of the market price of the secondary bandwidth service, as a result of the limited supply by CMEC plants, favouring market- based power plants. On 30 October 2019, EDP Produção filed an appeal against this decision before the Competition, Regulation and Supervision Court (TCRS), awaiting the AdC's counter-allegations. On 20 May 2020, EDP Produção was notified of an order from TCRS, which, among other things, admitted its Appeal of Judicial Contestation, establishing a purely return effect and determining the payment of the fine imposed within 20 days. In this context, EDP Produção submitted requests, invoking supervening facts to demonstrate the considerable damage associated with a putative payment of the fine, and arguing defects in the decision that determined the attribution of a merely devolutive effect to the Judicial Challenge Appeal. However, despite EDP Produção's well-founded convictions about the possibility of providing a bank guarantee or bond, instead of paying the fine, the TCRS ended up determining the payment of the fine, which occurred on 20 October 2021. The trial started in September 2021 and on 10 August 2022, the TCRS confirmed the AdC's decision, maintaining the fine of 48 million Euros to EDP Produção for alleged abuse of dominant position. EDP Produção filed an appeal against the aforementioned decision to the Lisbon Court of Appeal (TRL) on 30 September 2022. On 30 June 2023, an oral hearing was held at the aforementioned Court, which dealt only with legal aspects. By judgment rendered on 25 September 2023, TRL partially rejected the appeal filed by EDP Produção, confirming the sentence of TCRS that had convicted it, and also judged the appeal to be valid regarding the reduction of the fine amount. Consequently, TRL decided to reduce the fine imposed on EDP Produção from 48 million Euros to 40 million Euros. Given this decision, on 2 October 2023, EDP Produção filed a request with TRL to argue various issues in the ruling issued by the said court. On 9 October 2023, a request for an appeal to the Constitutional Court was filed, raising the unconstitutionality issues that had been raised by EDP Produção throughout the process and fulfilling the legal requirements necessary for the case to be sent to that jurisdiction. By judgment of 6 December 2023, the TRL dismissed the invalidities invoked by EDP Produção, and on 14 December 2023, EDP Produção submitted a request for clarification of part of the mentioned judgment. On 22 January 2024, the TRL deemed the request for correction of the judgment issued on 6 December 2023, as unfounded. On 5 February 2024, EDP Produção lodged an appeal to the Constitutional Court against the aforementioned TRL judgment that dismissed the request for clarification of part of the judgment of 6 December 2023. The decisions of the Constitutional Court regarding the admissibility of the appeals filed by EDP Produção and notification for the submission of written arguments are awaited. Nevertheless, in the context of this process, EDP Produção has already been judicially obliged to pay the fine to which it was sentenced by the AdC, even before the trial and the final decision of the TCRS.

Integrated Annual Report 2023 Financial Statements and Notes 

The EDP Group still considers that EDP Produção did not abuse any dominant position, having acted strictly in accordance with the legal framework in force. In the context of this process, on 29 September 2021, EDP Produção was cited in a class action filed by Associação IUS Omnibus based on the alleged abuse of dominant position in the secondary regulation band market between the beginning of 2009 and the end of 2013, requesting, in representation of consumers allegedly harmed, a compensation in the amount of 94.8 million euros, as estimated by AdC in the scope of process PRC/2016/05. EDP Produção has already presented its defense within the legal deadline established for that purpose. A rulling was issued in which the court decided, among other things, to suspend the proceedings until a final decision is made in the administrative offense case 309/19.0YUSTR. By rulling on 23 March 2023, adopted following an appeal filled by EDP Produção, TRL confirmed the decision to suspend the proceedings. EDP Produção filed a common appeal and, alternatively, an exceptional review appeal with the Supreme Court of Justice, and this court dismissed the appeals by ruling on 15 September 2023. ii) CMEC's revisibility overcompensation On 20 October 2020, EDP Produção became aware, by letter sent by DGEG, of the dispatch of the SEAE regarding the approval of the revisibility for the year 2015, which is deducted in the amount of 72.9 million Euros, relating to the alleged overcompensation. In this respect, the EDP Group has registered a provision in the amount of 72.9 million Euros, and carried out a judicial appeal against the order of SEAE at the Administrative Court of the Lisbon Circle at 19 January 2021. Innovative Features On 9 July 2018, EDP has been notified, within the scope of a stakeholder hearing promoted by the DGEG, to present its opinion on the possibility of DGEG proposing to the Secretary of State for Energy an amount associated with the alleged "innovative features" introduced in CMEC regime regarding PPA, to a maximum amount of 357.9 million Euros. According to DGEG, this amount shall be associated with the lack of legal scope for tests on the availability of the CMEC plants (285 million Euros) and the ancillary services, mentioned above (72.9 million Euros). On 26 September 2018, EDP Produção was notified of the Order of the SEE of 29 August, which considers as an "innovative features" the topic "procedures for calculating the verified availability coefficient", quantified at 285 million Euros. This Order refers to the alleged lack of legal forecast of availability tests of CMEC plants. Considering that the Order in question lacks technical, economic and legal basis, on 8 October 2018 EDP Produção has submitted an administrative appeal. Subsequently, EDP Produção received a letter from ERSE dated 12 November 2018 and became aware of the Order of the SEE of 4 October, which, following the Order of 29 August, declared the annulment of the annual adjustments in the part in which they considered the alleged "innovative features" concerning the procedures for calculating the coefficient of availability. In the Tariff and Price Document for 2019, ERSE considered the refund of an amount of 90 million Euros for a portion of the 285 million Euros referred to, expecting that the remaining portion will be paid for a number of years that allow the CMEC to have zero tariff impact by including the 86.5 million Euros in the tariffs of 2020, 86.5 million Euros in tariffs of 2021 and 21.9 million Euros in 2022. Without having received any response to the gracious complaint filed on 1 February 2019, EDP Produção challenged in court the Orders of 29 August and 4 October and the Tariff and Price Document for 2019. Although the EDP Group considers that there were no innovative features weighted in CMEC adjustments, this aspect was reflected in these financial statements as of 31 December 2018, by recognising a provision of 285 million Euros. In between 2019 and 2022, EDP made several payments, thus using the entire provision by 31 December 2022. Hydro power plants of Fridão and Alvito On 17 December 2008, EDP Produção and the Portuguese State signed the Contract for the Implementation of the National Program for High Hydroelectric Potential Power Plants (PNBEPH) regarding the Hydro Power Plants of Fridão (AHF) and Alvito (AHA), with the payment, by EDP Produção of 231,700 thousand Euros. Of this amount, 217,798 thousand Euros relates to the exclusive right to explore the AHF during the concession period. EDP Produção followed up on the procedures for the implementation of these projects, having, in the case of the AHF, obtained a Favourable Environmental Impact Declaration and an Environmental Compliance Report of the Execution Project (RECAPE). On 22 October 2013, EDP Produção requested to the Minister of the Environment, Land Management and Energy, based on a change of circumstances, to postpone the signing of the concession contract for the AHF. This request was formally rejected on 2 May 2014, and the terms of the concession contract, were subsequently negotiated between EDP Produção and the Portuguese Environmental Agency (APA) and a specific date for the respective signature for 30 September 2015, which was revoked by the Government without rescheduling a new date.

Integrated Annual Report 2023 Financial Statements and Notes 

In 2016, following the beginning of the XXI Constitutional Government, the Government Program provided the reassessment of the PNBEPH. In this context, it was suspended, for three years, the execution of the Contract for the implementation of the AHF, as well as was agreed the annulment of the implementation Contract regarding AHA, through a Memorandum of Understanding signed on 5 December 2016, concluded by an agreement between the Portuguese State and EDP Produção on 11 April 2017. On 16 April 2019 EDP Produção received, by email, an official letter from the Ministry of the Environment and Energy Transition, dated 11 April 2019, informing the State's conclusion that there is no need for implementation of AHF to meet national targets for energy production from renewable sources and for reducing the emission of Greenhouse Gases, as well as "that the State does not find any reason to inhibit the construction of the Fridão Hydro Power Plant". Simultaneously, the Minister of the Environment and Energy Transition announced at the National Assembly, in a hearing at the Environment, Land-use Planning, Decentralization, Local Power and Housing Committee, that the State's decision was not to build the AHF and that "the State will always comply with the contract but believes there are no reasons for any repayment of the amount that was given to the State ten years ago". It acknowledged, however, that there was no agreement with EDP on this matter. EDP Produção notified the Portuguese State to clarify that at no time did EDP express its intention to not proceed with the construction of power plants and to return all the investment already made, including the consideration paid on the provisional award, and, as well, to compensate it for other losses and damages resulting from the non-compliance, to be settled in a timely manner. The Group reclassified these Assets under construction to Other debtors and other assets and valued them in accordance with the principles defined in IFRS 9 (see note 28). On 24 January 2020, EDP Produção initiated an arbitration process against the State in which it claimed its rights. The arbitration hearing sessions took place during the month of April 2021 and in July 2021 the closing arguments were presented. In July 2022, the competent Arbitration Decision was handed down, obliging the State to refund to EDP Produção the aforementioned amount of 217,798 thousand Euros, which concerns the exclusive right to explore the AHF during the concession period. The other requests by EDP Produção and the State were dismissed. On 7 October 2022, the Portuguese State filed an appeal against the aforementioned Arbitration decision and EDP Produção presented its counter-claims on the 11 November 2022. On the 15 December 2022, the Supreme Administrative Court delivered the Judgment admitting the review appeal filed by the Portuguese State. In view of the decision of the Supreme Administrative Court to admit the State's appeal, EDP Produção filed an appeal with the Constitutional Court, that was admitted, and EDP Produção presented the respective allegations in March 2023 and the State the respective counter- allegations. Recognizing the impact of the decision that the Constitutional Court will adopt, on 5 May 2023, the Supreme Administrative Court issued an order suspending the instance until the result of that appeal is known. By judgment issued on 10 October 2023, the Constitutional Court did not deem unconstitutional the provision of article 185-A, paragraph 3, subparagraph b) of the CPTA, and consequently, dismissed the appeal of EDP Produção mentioned above, confirming the decision of the Supreme Administrative Court to admit the appeal for review. On 7 December 2023, EDP Produção was notified of the judgment issued by the Supreme Administrative Court, which dismissed the appeal and upheld the arbitral decision condemning the State to reimburse EDP Produção the amount of 217,798 thousand Euros. In parallel, on 13 December 2022, EDP Produção submitted an application for the execution of the aforementioned Arbitral Decision, demanding the payment of the amount for which the Portuguese State was condemned. The said application was admitted, and on 13 February 2023, the Ministry of Environment and Climate Action opposed the execution, specifically requesting the citation of the Public Prosecutor, as the representative of the Portuguese State. After being cited, the Public Prosecutor presented its opposition on 24 April 2023. EDP Produção submitted its Reply on 4 May 2023. By order of 24 July 2023, the Lisbon Administrative Court determined the suspension of the enforcement proceedings until a decision was made in the appeal filed before the Supreme Administrative Court. On 27 September 2023, EDP Produção lodged an appeal to the Central Administrative Court of the aforementioned order. In light of the aforementioned judgment issued by the Supreme Administrative Court, which dismissed the appeal and upheld the arbitral decision condemning the State to reimburse EDP Produção the amount of 217,798 thousand Euros, EDP Produção requested, on 13 December 2023, the continuation of the proceedings within the enforcement process, and on 7 February 2024, the Lisbon Administrative Court ordered the notification of the executed entities to come and inform the court, within 20 days, whether the decision issued on 14 July 2022, by the Arbitration Court has already been executed. Sale of the portfolio of Hydroelectric Projects The project for the sale of the portfolio of Hydroelectric Projects located in the Douro basin falls within the scope of EDP's strategic plan for 2019 2022, as presented to the market in March 2019 and reinforced with EDP's Strategic Plan for 2021-2025 presented in February 2021, in particular within the scope of the strategy of portfolio balancing and capital reallocation, as a way to finance new investments, particularly in renewable energy, including in Portugal.

The transaction was concluded on 16 December 2020, through the sale of the entire share capital of the company Camirengia Hidroelétricos S.A. (“Camirengia”), by its sole shareholder, EDP - Energias de Portugal, S.A. ("EDP"), to the company Movhera - Hidroeléctricas do Norte, S.A. (previously known as Águas profundas, S.A., company incorporated in Portugal and therefore resident for tax purposes in Portugal, owned by the consortium formed by GDF International SAS, from ENGIE Group, by 40%, Mirova S.A. by 35% and Predica Prevoyance Dialogue du Credit Agricole, S.A. in 25%). The company Camirengia was incorporated under the simple demerger of EDP - Gestão da Produção de Energia, S.A. ("EDP Produção"), under which a complex set of items was carved-out from this company, comprising not only the titles of use of the hydric resources related to the portfolio mentioned above, but also by a multiplicity of assets, liabilities, resources and contractual positions associated and necessary for the development of the exploration activity. From a strictly operational, regulatory, technical and legal point of view, the demerger was the only viable and feasible option to proceed with the detachment of the portfolio, considering its size and complexity. In this sense, EDP followed the only model, the demerger and the subsequent sale of shares, that guaranteed the continuity of operations and the maintenance of all the commitments (including environmental nature and towards the municipalities) necessary for the portfolio normal operation and also to respond to the need of the buyer of acquiring a functional and autonomous company that would ensure the operation of all activity, without disruption, immediately after the sale - which was also required by the regulator. On the other hand, the contractual model used in the implementation of the transaction is fully in line with market standards. After its conclusion, the transaction was subject to media attention, based on the assumption that it constitutes a transfer of concessions and that, therefore, would be subject to Stamp Duty (under paragraph 27.2 of the Stamp Duty General Table). In EDP's view, that assumption is not at all applicable, and Stamp Duty is not due, as the transaction did not entail a transfer of concessions, but rather a demerger followed by the sale of the entire share capital of a company (Camirengia) holding the patrimonial assets assigned to the portfolio, operations that are not subject to Stamp Duty. In this context, on 16 March 2021, the President of the EDP Executive Board of Directors was requested to attend the Environment, Energy and Spatial Planning Commission of the Portuguese Parliament, in order to address the abovementioned transaction, where EDP had the opportunity to clarify all questions addressed by the Members present. In addition, on 1 April 2021, that Commission sent EDP a request for information and questions about the transaction. On 15 April, EDP, committed to contribute to the swift, full and definitive clarification of the questions that were presented, sent to the Portuguese Parliament answers to all the questions raised, and made available all the requested documentation, despite its private and confidential nature, as a testament to the collaborative, transparent and good faith attitude with which EDP has been guiding its relationship with the State and its institutions. In this spirit of collaboration, transparency and good faith in its relationship with the State and its institutions, EDP proactively contacted the Tax Authority, making itself available to clarify the tax aspects of the operation. On 6 July 2021, EDP became aware that DCIAP is investigating the sale of the Douro portfolio, with searches carried out at the premises of EDP and EDP Produção. During the diligence, and basing its action on a cooperative posture, all cooperation and assistance was provided to the authorities. EDP scrupulously fulfils all of its obligations, including tax obligations, adopting very strict practices in the technical framework of all issues, having made this transaction under the tax framework applicable, assessing the tax rules in force on the date of the transaction, a framework that was also subject to validation by Opinions requested from reputable tax experts. 

5\. Financial risk management policies The military conflicts between Russia and Ukraine, which began on 24 February 2022, and between Israel and Hamas, which began on 7 October 2023, are having several impacts, namely in the financial markets, due to the volatility they entail, the uncertainty they carry, in a time when Central Banks are starting to announce the end of the tightening cycle and potential rate cuts, as a sign that inflation may now be controlled. The Group regularly monitors the financial markets evolution and the market variables to which it has exposure, seeking to mitigate that exposure by maintaining a mix of interest rate with a high percentage of fixed rate, maintaining prudent levels of foreign exchange hedging, choosing carefully its main counterparties favoring high ratings and high levels of liquidity (cash and available credit lines). The Group has adjusted its Financial Risk Management Policies incorporating worst case scenarios sufficiently conservative, therefore adequate to the Group profile. However, given that the duration of the conflicts and their global impacts are still unknown, the Group continues to monitor the risks, seeking to anticipate and manage possible additional impacts not currently contemplated.

Exchange-rate and interest rate risk management Financial risk management The EDP Group’s business is exposed to a variety of financial risks, including the effect of changes in market prices, foreign exchange and interest rates. The Group’s exposure to financial risks arises essentially from its debt portfolio, its investments and from the volatility of commodity prices, resulting in interest and exchange rate exposures as well as commodity market price exposure. The status and evolution of the financial markets are analysed on an on-going basis in accordance with the Group’s risk management policy. The management of financial risks of EDP, S.A. and other EDP Group entities is undertaken centrally by EDP, S.A., in accordance with policies approved by the Executive Board of Directors. The Financial, the Energy Management and the Risk Management Departments identify, evaluate and submit to the Board, for approval, hedging mechanisms appropriate to each exposure. The Executive Board of Directors is responsible for the definition of general risk management principles and the establishment of exposure limits. As for the subsidiaries of EDP Energias do Brasil, the management of the financial risks inherent to the variation of interest rates, exchange rates and commodities is carried out locally, according to the rules set by EDP Energias do Brasil's Management and aligned with the principles/policies set by EDP Group for this geographical area. Exchange-rate risk management EDP Group operates in different geographies, therefore becoming exposed to exchange rate risk in US Dollar (USD), Brazilian Real (BRL), Polish Zloty (PLN), Romanian Leu (RON), Canadian Dollar (CAD), Pound Sterling (GBP), Hungarian Forint (HUF), Colombian Pesos (COP), Singapore Dollar (SGD) and other asian currencies. Currently, these exposures result essentially from investments of EDP Group in wind parks (and solar) in the USA, Poland, Romania, Canada, United Kingdom, Hungary, Colombia and Singapore. The exposure to Brazilian Real results essentially from investments of EDP Group in EDP Energias do Brasil and EDP Renováveis Brasil. The majority of these investments were financed with debt contracted in the respective local currency which allows to mitigate the exchange rate risk related to these assets, and such financing is complemented, in certain cases, with derivative financial instruments to hedge exchange-rate risk on net investment. The policy implemented by the EDP Group consists of undertaking derivative financial instruments to hedge exchange rate risk with similar terms to those of the hedged asset or liability. The operations are revalued and monitored throughout their useful lives and, periodically, their effectiveness in controlling and hedging the risk that gave rise to them is assessed. Investments in the Brazilian subsidiaries of EDP Energias do Brasil, whose net assets expressed in Brazilian Real expose EDP Group to the exchange rate risk from its conversion to Euros, are monitored through analysis of the evolution of the BRL/EUR exchange rate. In the hedge relationships, the main source of ineffectiveness is the effect of the counterparties’ and the Group’s own credit risk on the fair value of the forward foreign exchange contracts and cross currency interest rate swaps, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in exchange rates. Sensitivity analysis - exchange rate Regarding the financial instruments that result in an exchange rate risk exposure, a fluctuation of 10% in the EUR/USD exchange rate, as at 31 December 2023 and 2022, would lead to an increase/(decrease) in the EDP Group results and/or equity as follows: Dec 2023 Dec 2022 Profit or loss Equity Profit or loss Equity Thousand Euros +10% -10% +10% -10% +10% -10% +10% -10% USD 1,166 -1,425 -19,352 23,653 9,696 -11,851 -65,279 79,785 This analysis assumes that all other variables, namely interest rates, remain unchanged. Interest rate risk management The aim of the interest rate risk management policies is to manage the impact on financial charges, from contracted debt, related to the exposure to interest rate risk from market fluctuations. In the floating rate financing context, the EDP Group enters, when considered appropriate, into interest rate derivative financial instruments to hedge the cash flows associated with future interest payments, which have the effect of converting floating interest rate loans into fixed interest rate loans. Long-term debt engaged at fixed rates is, when appropriate, converted into floating rate debt through interest rate derivative financial instruments designed to level them to current and expected market conditions.

Integrated Annual Report 2023 Financial Statements and Notes 

All the operations are undertaken on liabilities in the EDP Group’s debt portfolio and mainly involve perfect hedges, resulting in a high level of correlation between changes in fair value of the hedging instrument and changes in fair value of the interest rate risk or future cash flows. In the hedge relationships, the main source of ineffectiveness is the effect of the counterparty’s and the Group’s own credit risk on the fair value of the interest rate swaps, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in interest rates. The EDP Group has a portfolio of interest rate derivatives with maturities up to 17 years. The Group’s Financial Department undertakes sensitivity analysis of the fair value of financial instruments to interest rate fluctuations. As at 31 December 2023, after the hedging effect of the derivatives 79% of the Group's liabilities are at fixed rate. In 2022, the EDP Group also entered into forward-starting interest rate swaps, in EUR and USD, in order to pre-hedge its exposure to the risk of interest rates increasing until the expected refinancing date of its outstanding debt, for the following 2 years. Throught 2023, the pre-hedges in EUR were fully executed and the pre-hedges in USD were settled due to the changes in the internal policy, regarding the net investment hedge ratios. Sensitivity analysis - Interest rates (excluding the Brazilian operations) Based on the Group's debt portfolio, except for Brazil, and the related derivative financial instruments used to hedge the related interest rate risk, a 100 basis points change in the reference interest rates at 31 December 2023 and 2022 would lead to an increase/(decrease) in the EDP Group results and/or equity as follows: Dec 2023 Profit or loss Equity Thousand Euros 100 bp increase 100 bp decrease 100 bp increase 100 bp decrease Cash flow effect: Hedged debt -10,103 10,103 \- \- Unhedged debt -3,814 3,814 \- \- Fair value effect: Cash flow hedging derivatives \- \- 28,164 -28,164 Trading derivatives (accounting perspective) 18 -18 \- \- -13,899 13,899 28,164 -28,164 Dec 2022 Profit or loss Equity Thousand Euros 100 bp increase 100 bp decrease 100 bp increase 100 bp decrease Cash flow effect: Hedged debt -10,103 10,103 \- \- Unhedged debt -8,844 8,844 \- \- Fair value effect: Cash flow hedging derivatives \- \- 11,268 -11,268 Trading derivatives (accounting perspective) 68 -68 \- \- -18,879 18,879 11,268 -11,268 This analysis assumes that all other variables, namely exchange rates, remain unchanged. Brazil - Exchange and interest rate risk management Stress tests and sensitivity analysis are carried out for purposes of risk management in the Brazilian subsidiaries. Through these two tools, the financial impact in different market scenarios is monitored. For sensitivity analysis, the exposure of portfolio of operations is evaluated through 25% and 50% changes in the main risk factors, currency and interest rates, and the scenario with the highest probability of occurrence is presented (25%). The stress test is performed on the fair value of the operations and uses as premise the interest rate curve projections of the Brazilian basic macroeconomic scenario. Brazil - Sensitivity analysis - exchange rate Two Brazilian subsidiaries are mainly exposed to the USD/BRL exchange rate, arising from USD debt for which the exposure is completely offset by cross currency interest rate swaps.

Counterparty credit risk management EDP Group’s policy in terms of counterparty risk on financial transactions (see note 2 e)) is managed through an analysis of the technical capacity, competitiveness, credit rating and exposure to each counterparty, avoiding significant concentrations of credit risk. Counterparties in derivative financial instruments are institutions with high credit rating so the risk of counterparty default is not considered to be significant. Therefore, guarantees and other collaterals are not typically required for these transactions. EDP Group has documented its financial operations in accordance with international standards. Derivative financial instruments are mainly contracted under ISDA Master Agreements. The amount receivable from customers is mainly generated by operations in Portugal, Spain and Brazil, with a diversified customer base, both geographically and in terms of segments (business clients, private and public sector) and size (Supply companies, Business to Business (B2B) and Business to Consumer (B2C)). EDP Group is present in several countries and continents, structured in 4 regional hubs: Europe, Asia-Pacific, North America and South America. It has more than 9.2 million customers in the electricity and gas sectors, and usually the contractual relationship with the counterparty tends to be long-lasting. The maximum exposure to customer credit risk by counterparty type is detailed as follows: Thousand Euros Dec 2023 Dec 2022 Corporate and private sector: Supply companies 8,654 200 B2B 391,800 496,804 B2C 480,672 425,163 Other 562,336 556,939 1,443,462 1,479,106 Public sector: Debt with payment agreement 418 1,375 Debt without payment agreement 53,799 160,197 54,217 161,572 1,497,679 1,640,678 Trade receivables by geographical market for the Group EDP, is as follows: Dec 2023 Thousand Euros Portugal Spain Brazil USA Other Group Corporate and private sector 644,426 269,146 401,556 27,902 100,432 1,443,462 Public sector 32,806 2,177 18,785 \- 449 54,217 677,232 271,323 420,341 27,902 100,881 1,497,679 Thousand Euros Portugal Spain Dec 2022 Brazil USA Other Group Corporate and private sector 669,995 315,698 374,164 27,248 92,001 1,479,106 Public sector 34,223 112,988 13,909 \- 452 161,572 704,218 428,686 388,073 27,248 92,453 1,640,678 The amounts receivable from supply companies are concentrated mainly in Portugal, Brazil and EDP Renováveis Group, as follows: \- In Portugal, these counterparties present a significantly reduced days sales outstanding, about 20 days, and these entities are subject to the sector regulation that establishes collaterals to reduce credit risk. The collateral provided is updated based on the average of the last quarter monthly sales, which reinforces a low risk profile; \- In Brazil, it refers mainly to: (i) the amounts from sale of electricity to wholesale dealers and supply companies, (ii) accounts receivable relating to energy traded in the Electric Energy Trading Chamber - CCEE; and (iii) charges for the electricity network access;

\- In EDPR EU (Europe) & Latin America platform, main customers are utilities and regulated entities in the different countries. Credit risk is not significant due to the limited average collection period for customer balances and the quality of its debtors. Additional counter-party risk comes from the countries with renewables incentives, which it is usually treated as regulatory risk; \- In EDPR NA (North America) platform, main customers are regulated utility companies and regional market agents in the US. As it occurs in Europe, credit risk is not significant due to the limited average collection period for customer balances and the quality of the debtors. However, the exposure due to the mark-to-market of long term contracts may be significant; and \- In EDPR APAC (Asia-Pacific) platform, the Group’s main customers are Distributed Generation offtakers and regulated entities in the different markets, namely in Singapore and Vietnam. As it occurs in the other platforms, credit risk from trade receivables is not significant due to same reasons. However, counter-party risk comes from countries with renewables incentives through regulated tariffs, which it is usually treated as regulatory risk. Exposure in all markets EDPR operates is managed by a detailed assessment of the counter-party before signing any long term agreement and by a requirement of collaterals when financial soundness of the counterparty deteriorates. Regarding the remaining receivables from companies and individual customers, resulting from the current activity of EDP Group, the credit risk is essentially the result of customers defaults, whose exposure is limited to the supply made until the possible date of supply disruption. A very criterious credit risk analysis made for new costumers, the large number of customers and their diversity in terms of sectors of activity, as well as the realization of non-recourse factoring operations, are some of the main factors that mitigate the concentration of counterparty credit risk. Amounts receivable from public sector customers include amounts receivable from renegotiated debt with payment agreements, which, as the counterparty is a public entity and has already recognised the debt through payment protocols, present a lower risk. These amounts also include debt without payment agreements arising from the normal power supply activity similar to that described for the corporate and individual sector. In accordance with accounting policies - note 2 e), impairment losses are determined using the simplified approach precluded in IFRS 9, based on life time expected losses. Regarding third-party receivables generated by the Group’s day-to-day business, the credit risk arises essentially from customers default, whose exposure is limited to the Low Tension Electricity supplied with usual delays in payments. The very criterious credit risk analysis made for new costumers, as well as the large number of customers and their diversity in terms of sectors of activity are some of the main factors that mitigate the concentration of counterparty credit risk. EDP Group believes that the amount that best represents the Group's exposure to credit risk corresponds to the carrying amount of customers and of Contract assets related to energy sales net of the impairment losses recognised. The Group believes that the credit quality of these receivables is adequate and that no significant impaired credits exist that have not been recognised as such and provided for. As at 31 December 2023, in accordance with the methodology for determining impairment losses on amounts receivable from the electric sector, no impairment loss has been booked. The risk levels for amounts receivable from the electric sector have been considered to be the same as the country risk levels for Brazil, Portugal and Spain, which have high credit ratings. The maximum exposure to credit risk of Contract assets related to energy sales and Amounts receivable from the electric sector is as follows: Thousand Euros Dec 2023 Dec 2022 Contract assets related to energy sales: Amounts receivable from the electric sector: Amounts receivable from tariff adjustments - Electricity (see note 27) 401,702 483,217 Amounts receivable relating to CMEC (see note 27) 576,511 603,475 Amounts receivable from concessions - IFRIC 12 (see note 27) 1,695,957 1,966,939 2,674,170 3,053,631 3,931,352 4,503,591 

Liquidity risk management The EDP Group undertakes management of liquidity risk through the engagement and maintenance of credit lines and financing facilities, with a firm underwriting commitment with international reliable financial institutions, as well as term deposits, allowing immediate access to funds. These credit lines are used to complement and backup national and international commercial paper programmes, allowing the EDP Group’s short-term financing sources to be diversified (see note 35). Considering the military conflicts, the Group assessed the potential impacts on additional liquidity needs, having concluded that the current Liquidity Risk Management Policy remains adequate.

Energy market risk management Energy market risk management (excluding the Brazilian operations) Since 2022, following the strategic decision of implementing in the EDP Group a new platform management model, Energy market risk management is done through the Global Energy Management platform (GEM). GEM acts as an interface between the Generation and Renewable platforms and the Clientes platform, ensuring access to energy markets as a way of optimizing the group's risk positions across different geographies, being the preferred interlocutor in the energy markets. Managing the merchant energy as single portfolio seeks to capture the benefits resulting from the integrated management of the diversified portfolio, achieving an aggregate view of market risk, maximizing knowledge and operation synergies in the market. GEM's main functions are to optimize and manage the risks associated with the Group's position, resulting from the equilibrium between the production of its traditional and renewable assets and the needs of clients, by using short and long term, physical and financial energy markets. The portfolio is managed through the engagement of operations with financial and physical settlement on the forward/future energy markets. The objective of these operations is to reduce volatility of the financial impact resulting from the managed positions and to benefit from arbitration or positioning within the trading limits approved by the Executive Board of Directors. The activity is therefore subject to a series of variables which are identified and classified based on their common uncertainty characteristics (or risk). Such risks include market price evolution, volume, and shape risk as well as credit risk of the counterparties. The financial instruments traded mainly include energy commodities swaps and futures, for which, in the hedge relationships, the main source of ineffectiveness are: (i) the effect of the counterparty’s and the Group’s own credit risk on the fair value of the financial derivatives, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in market prices and (ii) the timing of the hedged transactions, that may differ from the settlement of the hedging instrument. Monitoring the risks includes their quantification in terms of positions at risk which can be adjusted through market operations. This quantification is made by using specific models that value positions to determine the maximum loss that can be incurred, with a given probability and a determined time frame. Risks are managed in accordance with the strategies defined by the Executive Board of Directors, which are subject to a periodic review based on the evolution of the operations, to change the profile of the positions and adjust them to the established management objectives. Risks are monitored by means of a series of actions involving daily monitoring of different risk indicators, of the operations grouped in the systems and the prudence limits defined by management area and risk component, as well as regular backtesting and supplementary validation of the models and assumptions used. This monitoring not only ensures the effectiveness of the strategies implemented, but also provides elements to enable initiatives to be taken to correct them, if necessary.

Dec 2022 Dec 2023 As of September 2023, the most important risk indicator is the Margin@Risk metric, which is a parametric calculation of the Value@Risk that gives visibility on individual risk elements of the Portfolio and different timeframe granularities but at the same time it provides the aggregated overall metric that considers diversification effect. The distribution by business segments is as follows: Margin@Risk distribution for next 24 months by business segment Thousand Euros Dec 2023 Dec 2022 Business Electricity Portfolio Trading 2,996 50,399 Electricity Trading + Hedging 606,061 425,008 Gas Hedging 101,693 622,867 Diversification effect -121,245 -116,768 589,505 981,506 Regarding credit risk, it is noteworthy that derivative financial instruments are traded both in market exchanges and through bilateral contracts (Over-the-counter – OTC). As per futures, forward derivatives traded in centralized market exchanges, given the requirements for the trading entities, namely margin deposits as collateral, credit risk is mostly mitigated and therefore excluded from exposure detailed below. As per derivative financial instruments contracted OTC, the quantification of exposure considers the amount and type of transaction (e.g. swap or forward), the rating of the counterparty risk that depends on the probability of default and the expected value of credit to recover, which varies depending on the guarantees received or the existence of netting agreements. The EDP Group's exposure to credit risk rating is as follows: Dec 2023 Dec 2022 Credit risk rating (S&P) A+ to A- 16.38% 25.09% BBB+ to BBB- 56.74% 47.47% No rating assigned 26.88% 27.44% 100.00% 100.00% Brazil - Energy market risk management Arising from the energy trading activity in Brazil, EDP Trading Comercialização e Serviços de Energia, S.A. and EDP Smart Energia Lda. are exposed to market price risk associated with future commitments, resulting from bilateral contracts for the purchase and sale of energy. At reporting date, the result of future commitment contracts is determined as the differential, for each maturity term, between the prices of the bilateral contracts for the purchase and sale of energy and their mark-to-market valuation using forward price curves. The result of future commitment contracts presents volatility associated with energy price fluctuation, generating market price risk. The management of market price risk is carried out through the determination and daily monitoring of the risk respecting the limits approved by the Management of EDP Brazil, and framed within the Risk Management Policy of the EDP Group, for the purchase and sale of energy using a methodology established in the Energy Risk Policy. The methodology adopted is a VaR (Value@Risk) with 95% confidence that considers a forward curve of market prices, the exposure of the portfolio (difference between purchase and sell) and the volatility and liquidity observed in the free market for each period. For sensitivity analysis, the exposure of portfolio of operations is evaluated through 25% and 50% changes in the forward curve of market energy prices. Below shows the scenario with the highest probability of occurrence (25%). Differences Settlement Price - PLD -14,014 12,644 -4,251 3,561

Following the capital increase, EDP kept the same 720,191,372 shares of EDP Renováveis that it previously held, and its stake in EDPR and its subsidiaries was diluted from 74.98% to 71.20%. On 4 April 2023, the Annual General Shareholders’s Meeting of EDP Renováveis S.A. approved for 2022 profits distribution through a scrip dividend to be executed as a share capital increase, through the issuance of new ordinary shares, with a par value of 5 Euros, without share premium.

EDP S.A., as per the intention communicated on 27 February 2023, opted to receive EDPR shares under this Programme, increasing its stake to 71.27% and holding 729,793,922 shares in EDP Renováveis. This changes in EDPR's participation resulted in a global gain of 381,579 thousand Euros. As a current operation with non-controlling interests and therefore with no loss of control, this gain was recorded in equity (see Consolidated Statements of Changes in Equity, notes 33 and 34); ● In the second quarter, EDP Ventures, S.A. reduced its stake in the joint venture ARQUILED - Proj. Iluminação, S.A. in 32.1%, maintaining a 17.8% financial interest in the company, which is recognized as an Equity Instrument at Fair Value through Profit or Loss.

("EDP Brasil"), representing 31.86% of its share capital, following the result of the Public Tender Offer ("Offer") auction, having reached the quorum for "Novo Mercado" Delisting. Therefore the necessary measures were taken for EDP Brasil's Registration Conversion and delisting of its shares from "Bolsa de Valores B3". Additionally, on 25 July 2023, and as communicated to the market on 26 July 2023, as a result of the acquisitions carried out in the context of the EDP’s obligation to extend the possibility of sale to those shareholders who did not sell on the Offer's auction during the subsequent three- month period, EDP’s aggregate shareholding in EDP Brasil’s share capital reached 538,259,059 common shares, representing approximately 92.62% of the total common shares issued by EDP Brasil. Therefore, and considering the total number of treasury shares (2.51%), EDP Brasil's outstanding shares came to represent less than 5% of the total common shares issued, reaching the threshold that allowed for the compulsory acquisition of the remaining outstanding shares, under the terms of the Offer notice.

Amortisation and impairment are as follows: Thousand Euros Group Dec 2023 Dec 2022 Compa Dec 2023 ny Dec 2022 Depreciation/impairment of Property, plant and equipment (see note 17) 1,376,625 1,371,272 6,158 6,156 Depreciation/impairment of Right of use asset (see note 18) 117,376 113,380 5,824 5,219 Amortisation/impairment of Intangible assets (see note 19) 564,685 514,968 23,840 19,359 Impairment of Non-Current assets held for sale (see note 42) 148,334 \- \- \- 2,207,020 1,999,620 35,822 30,734 Amortisation/impairment of Investment property (see note 24) 287 289 3,718 4,225 2,207,307 1,999,909 39,540 34,959 Compensation of depreciation Partially-funded property, plant and equipment (see note 39) -29,287 -28,579 \- \- Amortisation of Incremental costs of obtaining contracts with customers 7,966 7,677 \- \- Impairment of Goodwill (see note 20) 4,598 \- \- \- 2,190,584 1,979,007 39,540 34,959 

During 2023, due to the revision of market assumptions (in mainly, commodity prices and energy sales prices), the discount rates as well as the entry of renewable energy capacity, the Group carried out a review of its future estimates of value by carrying out impairment tests for some of the production assets. In the impairment tests carried out, EDP's energy transition strategy, namely the strategic goal of being "coal free" by 2025, was also considered, with a significant impact on the tests performed on the thermal generation assets (see note 49). The above impairment tests carried out led to the recording of the following impairments on assets in Portugal: 35,291 thousand Euros in the Lares combined cycle thermoelectric power plant, 51,321 thousand Euros in the Ribatejo combined cycle thermoelectric power plant and 22,074 thousans Euros in Greenvouga. Additionally, were also impairments in Colombia in the assets under construction at the wind farms of Eolos Energia and Ventos de Norte due to the delay in the start of operations (178,329 thousand Euros) and impairments were reversed in Romania in the amount of 37,797 thousand Euros(see note 17).

Integrated Annual Report 2023 Financial Statements and Notes 

The discount rates after taxes used reflect the best estimate of the specific risks of each cash generating unit, presenting the following variation bands: 2023 2022 Europe (EUR) 4,4% - 8,2% 3,7% - 4,8% North America (USD) 6,4%-8,2% 5,7% - 7,1% Brazil (BRL) 9,3% - 11,3% 7,9% - 9,6% Colombia (COP) 11% 9,3% APAC (SGD) 6,1% - 6,3% n.a. In the scope of impairment tests on these assets, sensitivity analyzes were performed on key variables, namely discount rates. An increase of +0.5% in the discount rate would determine an additional impairment of approximately: 5,485 thousand Euros in Lares, 6,712 thousand Euros in Ribatejo, 14,822 thousand Euros in Greenvouga and 46,425 thousand Euros in Eolos Energia wind farms and Ventos del Norte in Colombia. Additionally, given the changes in market conditions, impairments amounting to 4,206 thousand in the coal-fired power plant in Spain in Los barrios and 28,982 thousand in the coal-fired power plant in Soto3 were performed (see note 17). 

13\. Other non recurring income and expenses (Company basis) On 1 February 2023, EDP S.A. entered into a transfer ("trespasse") agreement with EDP GEM Portugal, S.A. (EDP GEM) with the aim of transferring its energy management business unit. This transfer of activity results from the global vision of energy management that the EDP Group has been developing which includes the transfer to EDP GEM of all assets, liabilities and contractual positions that make up that business unit, as well as its employees and associated means necessary to carry out its activity. The total amount of the operation was 1,169,510 thousand Euros. On the transaction date, the book value of the net assets transferred under this contract was 228,858 thousand Euros and a gain of 940,653 thousand Euros was recorded. As a result of this agreement, EDP S.A. transfers its energy management activity, so with reference to 1 February 2023, all existing cash flow hedges (related to foreign exchange, purchase and sale of electricity, gas and CO2) have been discontinued, reclassifying the cash flow reserve in the negative amount of 1,014,219 thousand Euros to profit or loss, since the underlying transactions subject to hedging were transferred to EDP GEM under the terms of the transfer agreement, and as such will not occur at EDP S.A. The operationalization of this transfer occurs through the assignment of EDP S.A's contractual positions in favor of EDP GEM, with a back-to- back mechanism also foreseen for contractual positions whose assignment requires the fulfillment of formalities by third parties unrelated to EDP S.A., until such formalities are fulfilled. During this period, EDP GEM undertakes to assume all the risks and benefits associated with those positions, assuming EDP S.A. as an agent in relation to the rights and obligations that emerge from them. Since the transfer of the energy management business unit is a specific and unique transaction within the scope of the individual financial statements of EDP S.A., it was considered that the result generated should be presented separately in the operating results of EDP, S.A. On the same day and pursuant to this agreement, EDP S.A., the sole shareholder of EDP GEM, approved the provision of supplementary pecuniary capital contributions under the applicable rules for additional contributions, in the global amount of 1,000,000 thousand Euros (see note 21). 286

14\. Financial income and expenses 

Financial income and expenses, for the Group, are as follows: 

Thousand Euros Group Dec 2023 Dec 2022 Financial income Interest income from bank deposits and other investments 133,522 80,689 Interest from derivative financial instruments 72,521 33,600 Interest income on tariff deficit: \- Portugal - Electricity (see note 27) 37,166 111 \- Brazil - Electricity (see note 39) 6,257 16,664 Other interest income 87,809 65,002 Derivative financial instruments 288,965 223,328 Foreign exchange gains 283,784 353,572 CMEC: \- Interest on the initial CMEC 20,404 23,950 \- Financial effect considered in the calculation 6,667 7,147 Other financial income 42,403 38,937 979,498 843,000 Financial expenses Interest expense on financial debt 836,313 705,812 Bonds buyback 4,802 \- Capitalised borrowing costs: \- Assigned to concessions (see note 7) -6,355 -4,442 \- Other (see note 17) -131,176 -41,405 Interest from derivative financial instruments 211,419 134,765 Interest expense on tariff deficit: \- Portugal - Electricity (see note 27) 2,306 4,484 \- Brazil - Electricity (see note 39) 9,253 16,079 Other interest expense 38,182 40,063 Derivative financial instruments 465,797 259,167 Foreign exchange losses 161,920 356,958 CMEC 3,006 5,231 Unwinding of discounted liabilities 138,191 140,955 Unwinding of lease liabilities (see note 40) 47,718 46,146 Net interest on the net pensions plan liability (see note 36) 9,610 5,132 Net interest on the medical liabilities and other benefits (see note 36) 20,029 14,985 Other financial expenses 78,679 69,290 1,889,694 1,753,220 Financial income/(expenses) -910,196 -910,220 

Capitalised borrowing costs includes the interest capitalised in assets under construction according to Group accounting policy (see note 2 h)). Regarding the rate applicable to borrowing costs related with tangible/intangible assets under construction that is used in the determination of the amount of borrowing costs eligible for capitalisation (see notes 17 and 19), it varies depending on business unit, the country and currency, since EDP Group incorporates in its scope of consolidation a significant number of subsidiaries in several geographies with different currencies. Therefore, for the most representative geographies, the funding rates, in use in 2023, ranged from 1.52% to 4.63% in Portugal, from 1.05% to 4.69% in Spain and from 2.28% to 8.22% in North America, depending on related assets under construction and related financing. 

The costs related to the Unwinding of discounted liabilities refer essentially to: (i) the unwinding of the provision for dismantling and decommissioning of production assets in the amount of 16,804 thousand Euros (31 December 2022: 6,609 thousand Euros) (see note 37); (ii) the implied financial return in institutional partnerships of 81,058 thousand Euros (31 December 2022: 96,955 thousand Euros) (see note 38); and (iii) the financial expenses related to the discount of the liability associated to the concessions of Alqueva/Pedrógão, Investco and Enerpeixe of 12,230 thousand Euros (31 December 2022: 20,700 thousand Euros). The Derivative financial instruments caption includes income and expenses related with financial assets and liabilities measured at fair value through profit and loss, while the remaining captions of financial income and expenses arise from financial instruments are registered at amortised cost, based on the effective interest rate method. The caption Other financial income includes the sale of the electricity tariff deficit of 2024 that generated a gain, after deducting all transactional expenses, in the amount of 13,306 thousand Euros (see note 27).

Financial income and expenses, for the Company, are as follows: Thousand Euros Compa Dec 2023 ny Dec 2022 Financial income Interest income from loans to subsidiaries and related parties (see note 45) 130,328 36,156 Interest from derivative financial instruments 191,577 106,745 Derivative financial instruments 510,795 444,047 Income from equity investments (see note 45) 930,118 1,003,733 Reversal of impairments on equity investments and shareholders loans 26,630 \- Other financial income 24,961 59,747 1,814,409 1,650,428 Financial expenses Interest expense on financial debt 297,618 194,411 Bonds Buyback 4,802 17,882 Interest from derivative financial instruments 199,873 119,570 Derivative financial instruments 487,327 425,300 Unwinding of lease liabilities 5,733 5,874 Impairment on equity investments and shareholders loans 5,888 26,630 Other financial expenses 48,441 69,058 1,049,682 858,725 Financial income/(expenses) 764,727 791,703 On January 2023, EDP S.A. has repurchased an amount of 672,800 thousand Euros from the issue "EUR1.000.000.000 Fixed to Reset Rate Subordinated Notes due 2079", recognising a cost of 4,802 thousand Euros, on a consolidated and individual basis. The caption Other financial income includes 5,397 thousand Euros related to nominal interests from bonds issued by EDP Finance B.V., repurchased by EDP S.A. (see notes 28 and 45). The effective interest of these instruments amounts to 1,291 thousand Euros (includes the recognition in profit or loss of premium and transaction costs associated with the buyback transaction by the effective interest rate method). The fluctuation on Other financial income and expenses, on an individual basis, is mainly explained by the impact of the foreign exchange of the American Dollars. 

15\. Income tax The following note includes an analysis on the reconciliation between the theoretical and the effective income tax rate applicable at an individual level and at the level of the EDP Group, on a consolidated basis. In general terms, this analysis aims to quantify the impact of the income tax, recognised in the income statement, which includes both current and deferred tax. As the EDP Group prepares and discloses its financial statements in accordance with IFRS, an alignment between the accounting of income tax expense or income and the corresponding cash flow is not mandatory. Accordingly, this analysis does not represent the income tax paid or received by the EDP Group for the correspondent reporting period. The overall tax contribution borne by EDP Group (which includes comments on the contributions paid to the respective states where the Group operates), as well as other relevant information (such as EDP Group's tax footprint, specific taxation over energy sector and procedures to control and manage adverse tax exposures), are disclosed on this annual Integrated Report. The general principles concerning EDP Group's mission and tax policy are also addressed in the same report as well as on its website (www.edp.com). This document also describes the key principles with respect to the transfer pricing policy applicable to EDP Group, under which the Group's policy is to abide within the international rules, guidelines and best practices applicable in the various geographies where it operates. It should be noted that, as a multinational group, EDP Group fully complies with the annual obligation of communication and report, which results from the transposition into the Portuguese domestic Law of the disposals of Action 13 of the Base Erosion and Profit Shifting (named Country-by Country Reporting), as a part of a set of measures adopted by OECD and G20 countries to enhance transparency for tax administrations. Furthermore, this obligation is fulfilled in Portugal by the parent company, within the deadlines foreseen by law.

Integrated Annual Report 2023 Financial Statements and Notes 

Main features of the tax systems of the countries in which EDP Group operates The statutory corporate income tax rates applicable in the main countries in which EDP Group operates are as follows: Dec 2023 Dec 2022 Europe: Portugal 21% - 31.5% 21% - 31.5% Spain 24% - 25% 24% - 25% Netherlands 19% - 25.8% 15% - 25.8% France 25% 25% Italy 24% - 28.8% 24% - 28.8% Poland 19% 19% Romania 16% 16% Greece 22% 22% Asia Singapore 17% 17% Vietnam 20% 20% America: Brazil 34% 34% Colombia 35% 35% United States of America 24.91% 24.91% Canada 23% - 26.5% 23% - 26.5% Mexico 30% 30% EDP Group companies are taxed, whenever possible, on a Group consolidated basis as allowed by the tax legislation of the respective countries. As per the applicable legislation, in general terms, the corporate income tax for a fiscal year may be subject to review and reassessment by the tax authorities during a limited period of time. In Portugal, this period is 4 years, or, if tax losses or credits have been used, the number of years that such tax losses or credits may be carried forward. In Spain, the general period is 4 years, in the Netherlands and in Brazil it is 5 years and in the USA it is 3 years. In other key jurisdictions, the statute of limitation period ranges between 2 and 12 years. Tax losses generated in each year are also subject to the tax authorities' review and reassessment and may be carried forward and set off against income over a time period and limits established in each jurisdiction. In Portugal, Spain, USA, Brazil and the Netherlands, tax losses may be carried forward indefinitely. Moreover, in the Netherlands the tax losses of a given year may be used to recover current tax of the previous year with limitations. However, the deduction of tax losses in Portugal, Spain, the Netherlands, USA and Brazil may be limited to a percentage of the taxable income of each period or is subject to other limitations. EDP Group companies may, in accordance with the law, benefit from certain tax benefits or incentives in specific conditions, namely the Production Tax Credit in North America, which represent an extra source of revenue per unit of electricity, over the first 10 years of the asset’s life. Wind and Solar facilities that achieve commercial operations by 2022 or later qualify for the application of the Production Tax Credits ($2.75/KWh being adjusted for inflation in subsequent years). Alternatively, EDP Group companies can, instead of the production tax credit, choose to benefit from the Investment Tax Credit which avails solar and wind projects to a credit based upon its capital expenditures. This credit amount equates to 30% for projects that achieve commercial operations by 2022 or later. Additionally, this credit can increase to 40% or 50% dependent on the i) the use of domestic made equipment and/or ii) locating a project in an economically depressed area or an area that once had a traditional energy facility. Relevant events for EDP Group in 2023 On 22 December 2022, European Union adopted Directive 2022/2523 (Pillar 2), on ensuring a global minimum level of taxation for multinational enterprise groups and large-scale domestic groups in the Union. These rules aim to ensure that multinational enterprises that operate in EU pay an effective minimum rate of tax of 15% on their profits, regardless of the country in which those profits are generated. The directive should have been transposed by Member States by 31 December 2023. Taking into account the preliminary analysis carried out and EDP Group´s consolidated revenues, it is expected that the Group will be subject to this tax regulation. Portugal did not comply with the transposition deadlines, although it is expected that such transposition occurs during 2024. However, assuming that the transposition will strictly follow the Directive, no top-up tax is expected to be paid by EDP Group. In the countries where EDP Group carries out its activities and where the Pillar 2 rules were already enacted, we expect the safe harbours will apply and therefore no additional tax will be due.

The caption Accounting/fiscal differences on the recognition/derecognition of assets mainly includes the impact related to the non-taxation of capital gains resulting from the sale of a set of wind farms in Europe (see note 6). The caption Different tax rates (includes state surcharge) and CIT rate changes mainly refer to the difference between the tax rates applicable in the countries in which the EDP Group operates as compared to the tax rate used as reference for the theoretical income tax expense calculation. The caption Taxable differences attributable to non-controlling interests (North America) include the effect inherent in the attribution of taxable income to non-controllable interests in EDPR Group in the USA, as determined by the tax legislation of that geography.

Integrated Annual Report 2023 Financial Statements and Notes 16\. Extraordinary contribution to the energy sector (CESE) Law 83-C/2013, of the State Budget 2014 ("Lei do Orçamento de Estado 2014"), approved by the Portuguese Government on 31 December 2013, introduced CESE, with the objective of financing mechanisms that promote the energy sector systemic sustainability, through the establishment of a fund which aims to contribute for the reduction of tariff debt and to finance social and environmental policies in the energy sector. This contribution focuses generally on the economic operators that develop the following activities: (i) generation, transmission or distribution of electricity; (ii) transportation, distribution, storage or wholesale supply of natural gas; and (iii) refining, treatment, storage, transportation, distribution and wholesale supply of crude oil and oil products. CESE is calculated based on the companies’ net assets as at 1 January, which comply, cumulatively, to: (i) property, plant and equipment; (ii) intangible assets, except industrial property elements; and (iii) financial assets assigned to concessions or licensed activities. In the case of regulated activities, CESE focuses on the value of regulated assets if it is higher than the value of those assets. The general rate is 0.85%. However, in case of natural gas combined cycle power plants with an annual utilization equivalent of installed capacity equal or higher to 1,500 hours and lower than 3,000 hours, is expected a reduced rate of 0.565%. Nevertheless, this rate could be 0.285% in case the annual utilization of installed capacity is lower than 1,500 hours. The CESE system has been successively extended and is now valid for 2023 through Law nº 24-D/2022 of 30 December. EDP has paid 558,205 thousand Euros relating to CESE so far. As at 31 December 2023, the Group booked under the caption Extraordinary contribution to the energy sector (CESE) in the Consolidated Income Statement, the amount of 49,365 thousand Euros (31 December 2022: 51,534 thousand Euros), having chosen not to make the respective payment.

Ltd. and its subsidiaries (see note 6). The Decreases/Regularisations include the impact of the sale of an onshore wind generation portfolio in Spain, in the amount of 53,888 thousand Euros (see note 6), as well as adjustments resulting from business combinations carried out over the last 12 months and whose assessment to determine the fair value of assets and liabilities is still ongoing. Additionally, include the amount of 2,830 thousand Euros referring to the reclassification of goodwill related to a solar portfolio in North America to non-current assets held for sale (see note 42). 

Goodwill impairment test analysis – EDP Group The recoverable amount of the goodwill in subsidiaries is assessed annually, as at 30 September, independently of the existence of any indicators of impairment. The recoverable amount of assets correponds to the higher of their fair value less costs to sell and the value in use of the assets, calculated using valuation methodologies supported by discounted cash flow techniques, considering market conditions, the time value of money and the business risks. Any impairment losses are recognised in the income statement for the period. Following the Strategic Plan Update 2023-2026, announced in the last 2 March 2023, the Executive Board of Directors reorganized the business segments in order to be aligned with this new view, with effect from 1 January 2023 (see note 51). EDP Group segments based on which the Group monitors its activity are as follows: • Renewables, Clients & Energy Management - corresponds to the activity of generation of electricity from renewable sources, mainly hydro, wind and solar. This segment also includes the following activities: generation of electricity from non-renewable sources, mainly coal and gas, electricity and gas supply, including last resort suppliers, and related energy solutions services to clients; and energy management businesses responsible for management of purchases and sales of energy in Iberian and Brazilian markets, and also for the related hedging transactions; and • Networks - corresponds to the electricity distribution and transmission activity, including regulated energy retailers; For the purposes of these tests, the EDP Group has defined a set of assumptions to determine the recoverable amount of the main investments by each cash generating unit, being presented by aggregation in each business units after the impairment tests carried out at each subgroup/cash generating unit. Goodwill impairment test analysis – Renewables, Clients & Energy Management The future cash flows are based on the useful life of wind farms, solar and hydro assets. This projection also considers long-term energy sales contracts and long-term energy price estimates, for assets with market exposure. The main assumptions on which impairment tests are based are as follows: \- Regarding the production of wind and solar energy, the “net capacity factors” used for each cash-generating unit consider: (i) the installed capacity and the forecast resulting from the studies on the occurrence of wind in the long term; and (ii) that regulatory mechanisms in almost all geographies determine the production and priority of energy dispatch whenever weather conditions permit; 

295 

Integrated Annual Report 2023 Financial Statements and Notes 

\- Regarding hydro production, the “net capacity factors” used for each cash-generating unit consider: (i) the installed capacity and the forecast for hydraulic production; and (ii) that the regulatory mechanisms in each geography; \- Energy remuneration: the approved or contracted remunerations were considered in the event of long-term energy sales contracts for the total or partial useful life of the assets or remunerations determined by the regulatory framework in force in each geography. In the remaining cases, the long-term market price curves projected by the Group were used based on past experience and internal models built on the basis of external information sources; \- Operating costs: the land and maintenance contracts in force were used. The other operating costs were projected consistently based on the experience acquired, on the Budget approved for the next year and taking into account internal analysis models; \- Terminal value: considered as a 15% of the initial investment in each wind farm, considering inflation; and \- Discount rate: the discount rates used are post-tax and reflect EDP Group’s best estimate of the risks specific to each CGU (see note 12). Impairment tests were performed taking into account the regulatory changes in each country known at the end 2023. The impairment tests carried out on Goodwill did not lead to any impairment registration in 2023. Goodwill impairment test analysis – Networks The cash flow projection assumes the extent of the concessions related to the electricity distribution business in Brazil. In the case of the concession in Spain, it is perpetual. These cash flows are estimated considering the volume of production and expected consumption, installed capacity, the evolution forecast of the tariff and the energy purchase / sale agreements. The discount rates after taxes used are disclosed in Note 12. The main assumptions used to project cash flows are as follows: \- Investment costs: the best available estimates of the investments to be made were used to ensure regular use of current assets, as well as those resulting from legislative changes; \- Regarding operating costs, the projections made considered the current operating costs projected based on the historical experience acquired, in the Budget approved for the next year and taking into account internal models of analysis; \- The most recent remuneration rates proposed by ANEEL and CNMC ("Comisión Nacional de los Mercados y la Competencia") were considered, applying the updating mechanisms as provided for in the regulation; \- The projections for the electricity distribution businesses are based on long-term estimates of the various assumptions considered in the analysis; and \- The terminal value of the distribution assets corresponds to the present value of the net assets at the end of the concession ("Net Regulatory Asset Base”). Sensitivity analyzes were carried out on the results of the impairment tests carried out, namely at discount rates. The results of the sensitivity analyzes carried out conclude that an increase of 50 basis points in the different discount rates, does not determine the existence of signs of impairment in "goodwill" or concession rights.

During the third quarter, EDP Gestão de Produção de Energia, S.A. carried out a capital reduction in the amount of 2,734,350 thousand Euros. The remaining variation in the caption Investments in subsidiaries results from capital increases made in some investees, namely, in E-Redes - Distribuição de Eletricidade, S.A. (1,959,581 thousand Euros), EDP International Investments and Services, S.L. (876,846 thousand Euros), and EDP GEM Portugal, S.A (1,000,000 thousand Euros), as well as from the reversal of impairment recorded in EDP GEM Portugal, S.A. (see note 14). In the context of impairment tests carried out at EDP Group, the financial investments held by EDP, S.A. in subsidiaries are reviewed, based on the higher of the value in use and the fair value less costs related to the sale. The main assumptions considered in the valuation models of the main financial holdings in Portugal of EDP, S.A. are as follows: \- The discount rates used reflect the best estimate regarding the specific risks associated to each subsidiary activity within a range between 4.7% and 6.4% (2022: between 3.7% and 5.8%); \- For the activities subject to regulation, the remunerations currently in force and/or approved were considered, applying the updating mechanisms as provided for in the regulation, and incorporates the expectation of renewal of the concessions currently in force and the best estimate of CAPEX and the future regulatory framework; \- Fuel prices (brent, gas, coal and CO2 licenses) and electricity prices forecast were defined considering market expectations for future prices and the application of internal models for building price curves, taking into account the regulatory framework in force and the best expectation regarding its future evolution. Regarding fuel prices, the prices and clauses established in long-term supply contracts, including gas purchase contracts, were also considered. Production assets were valued from a portfolio management perspective, without prejudice to an individual analysis as to recoverability, based on the estimate of the evolution of the market share; \- The production estimates were based on an average hydrological year over the projection period for the hydroelectric plants, the estimated evolution of demand, market share projections and current installed and under construction capacity, as well as the best estimate of the plants to be decommission in the projection period; \- Additionally, other system costs are considered, such as: ISP and CO2 addition fee, CESE and other income; and \- The operating costs considered were based on extrapolations from current operating costs based on the knowledge acquired in each activity. The impairment tests mentioned above did not result in the recording of any impairment in 2023. The assumptions used in the valuation models of EDP S.A.'s financial holdings in other geographies, as well as the respective sensitivity analyses are described in note 20. 297

Brazil Increase Decrease Spain Increase Decrease Decrease Increase Thousand Euros Portugal Following the decision and implementation of the autonomisation of the Medical Plan and Death Subsidy Plan in Portugal, EDP Group has made contributions of 5,585 thousand Euros in 2023 (31 December 2022: 34,560 thousand Euros). We noticed that as of 31 December 2022 and 2023, the liabilities for Death Subsidy Plan in Portugal were fully financed. Therefore, in the following years, until the end of 2027 and in the scenario where the liabilities associated with the Medical Plan are not 100% financed, the Group estimates to make additional contributions in the approximate total amount of 44,676 thousand Euros, in line with the financing plan approved by Insurance and Pension Funds Supervisory Authority (ASF) (see note 45). The Pension Plans in Portugal, Spain and Brazil are subject to several risks, in which are included the risk of changes in market rates (which impacts the discount rate and the fixed rate of return rate on assets), the risk of changes on the expected lifetime of plan participants, the risk of changes on the pension increase rate and the risk of changes on the social security pension increase, to which are made the following sensitivity analysis for the liabilities at the end of the period: Discount rate (0.5% movement) -26,477 28,473 -132 122 -11,441 12,419 Mortality (increase of 1 year in expected lifetime of plan participants) 30,970 \- 4,724 The solvency level of the fund for the financing of pension plan liabilities in Portugal may vary not only from the risks described above, but also from the performance of the different classes of assets that comprise it. Considering the nature of the defined benefit of the plan and despite the fund's low risk profile (mostly composed of fixed income assets), the joint materialization of adverse risks (including those above referred) may lead to the need for additional contributions to the fund. The medical care and other benefits Plans in Portugal, Spain and Brazil are subject to several risks, in which are included the risk of changes in market rates (which impacts the discount rate and the fixed rate of return rate on assets), the risk of changes in the health care costs and the risk of changes on the expected lifetime of plan participants, to which are made the following sensitivity analysis for the liabilities at the end of the period: Thousand Euros Portugal Increase Decrease Increase Spain Decrease Increase Brazil Decrease Discount rate (0.5% movement) -36,701 40,509 -2,935 9,491 -8,814 5,911 Health care cost trend (0.5% movement) 12,465 -11,527 \- \- \- \- Mortality (increase of 1 year in expected lifetime of plan participants) 12,851 \- 4,521 The level of solvency of the fund for the financing of post-employment medical care liabilities in Portugal may vary not only from the risks described above, but also from the performance of the different classes of assets that comprise it. Considering the nature of the defined benefit of the plan and despite the fund's low risk profile (mostly composed of fixed income assets), the joint materialization of adverse risks (including those above referred) may lead to changes in the financing plan approved by ASF.

Provision for legal and labour matters and other contingencies includes provisions for litigation in progress and other labour contingencies, which are related essentially with: i) Requests for the refund of tariff increases paid by industrial consumers of the brazilian subsidiaries EDP São Paulo and EDP Espírito Santo in the amount of 20,773 thousand Euros (31 December 2022: 17,181 thousand Euros). These requests result from the application of Administrative Orders DNAEE no. 38 of 27 February 1986 and no. 45 of 4 March 1986 - Plano Cruzado, effective from March to November 1986; ii) The remaining legal litigations correspond mainly to indemnities for damages allegedly suffered in consequence of interruption of electricity supply, power accidents and fires. Provisions for customer guarantees under current operations include essentially provisions for commercial losses.

Provisions for dismantling and decommissioning includes : (i) 40,161 thousand Euros of the dismantling Trillo nuclear power plant; (ii) 294,730 thousand Euros of the dismantling of wind and solar farms (replacement of sites and land in its original state), mainly, in Europe (116,758 thousand Euros), North America (133,033 thousand Euros), Asia-Pacific (40,330 thousand Euros) and Brazil (4,609 thousand Euros); and (iii) 172,918 thousand Euros of the dismantling and environmental requalification of thermal electro-producing centers in Spain (101,620 thousand Euros) and Portugal (71,298 thousand Euros). As part of its energy transition strategy, the Group has been progressing in the dismantling and reconversion of its coal-fired power plants. This commitment is evidenced by the ongoing process at the Sines coal-fired power plant in Portugal, which is already being dismantled and has plans to convert into hydrogen. In this regard, a request was also made during the year 2023 for authorisation from the Spanish electricity system operator (Red Eléctrica) to close the Aboño I coal-fired power plant, as well as the remaining EDP coal-fired power plants in Spain (Soto 3 and Los Barrios). EDP has been investing in the adaptation of these facilities in Spain (Abono, Soto, and Los Barrios) to new technologies, specifically in the creation of Hydrogen and Storage Hubs (see note 49). These provisions were calculated based on the present value of future liabilities and recorded against an increase in the respective tangible fixed assets, which are amortized over the average useful life of these assets. The calculation of these provisions was based on the following discount and inflation rates: Europe North America Brazil Asia-Pacific Discount Rate [2.74% - 7.09%] [3.85% - 11.34%] [11.73% - 11.83%] [1.43% - 5.12%] Inflation Rate [1.96% - 6.07%] [2.01% - 3.95%] [3.62% - 4.50%] [1.31% - 3.68%] Provision for other liabilities and charges The BOE 223/2017 published during the third quarter of 2017 opened the hearing process of the Order of the Minister of Energy, Tourism and Digital Agenda of 13 September, introducing "lesividad" declaration procedure for the public interest Order IET/980/2016, of 10 June, which established the remuneration of electricity distribution companies until 2016. Thus, the remuneration that has been determined has allegedly been higher than that due for the year 2016. Until the "lesividad" procedure is finitely resolved, the remuneration of the distribution activity for the years 2016, 2017, 2018 and 2019 is considered provisional. With reference to 31 December 2020, EDP España recorded an accumulated provision of 93,105 thousand Euros corresponding to the potential effect of "lesividad" for the financial years 2016, 2017, 2018, 2019 and 2020. Since 2016, EDP España, like other companies in the sector, have been in place with legal proceedings to resolve the “lesividad” procedure. At the same time, companies initiated processes to determine the real value of assets subject to remuneration and proceeded with the reformulation and deposit of their annual accounts from 2014 to 2020, ending this process during 2021. Although no new liquidation or a new regulation has been issued, the companies consider that, in accordance with the order 481/2020 of the Supreme Court, the reformulated and deposited annual accounts must be considered for the calculation of the remuneration. Thus, in 2021, EDP España updated the provision for the “lesividad” procedure for the years 2016 to 2020, reversing it by approximately 47 million Euros. On 1 June 2022, order TED/490/2022, of 31 May, was published in BOE 130/2022, which executes the judgment of the Federal Supreme Court in relation to the declaration of "lesividad" to the public interest of the Order IET/980/2016, of 10 June. The remuneration approved by the Ministry of Ecological Transition and the Demographic Challenge in the referred Order did not take into account the accounts reformulated by the distribution companies, resulting in a notable decrease in their remuneration compared to the expected and accounted values corresponding to a correct execution of the sentence. Subsequently, the "Comisión Nacional de los Mercados y la Competencia" (CNMC) settled the payment obligations arising from the "lesividad" referring to the years 2016, 2017, 2018, 2019, 2020 and 2022 in the Provisional Agreement 5/2022 (partially corresponding to the year 2022) approved by the CNMC on 14 July 2022 and those corresponding to the 2021 financial year in the “2021 Definitive Settlement of regulated activities in the electricity sector”, approved by the CNMC on 4 November 2022. The distribution companies of the EDP Group filed lawsuits against order TED/490/2022 and against the Final Settlement of 2021, in order to obtain the collection of amounts due from a correct execution of the judgment. Before the publication of order TED/490/2022, the provisions corresponding to the expected impact of the execution of the sentence amounted to approximately 47 million Euros. After its publication, the existing provisions were used for this purpose, with the Group recording a receivable in assets, awaiting the decision of the respective lawsuits filed against order TED/490/2022. During 2023, the legal proceedings opened against the order TED/490/2022 by the EDP Group continued to evolve as expected, with a favourable decision being received for Viesgo Distribución Eléctrica on 17 January 2024. In the case of Hidrocantábrico Distribución Eléctrica, the vote and judgment are scheduled for 9 April 2024. The amount expected to be received for the period 2016-2022 amounts to 72 million Euros, with an additional amount of about 9 million Euros for the financial year 2023.

On 3 May 2018, it has come to EDP’s knowledge (through a DGEG’s letter) that the CMEC final adjustment had been officially approved, according to ERSE’s proposal, in the amount of 154 million Euros. EDP reflected this reality in its financial statements as of 31 December 2018, recognising a provision by the difference in the final adjustment amounts already recognised in the Group's revenues. On 31 December 2023 EDP maintains the provision in its accounts (see note 4). On 26 September 2018, DGEG notified EDP about a dispatch issued by the Secretary of State for Energy (SSE) on 29 August 2018, which quantifies at 285 million Euros the alleged overcompensation of EDP related to the calculation of the real availability factor of the plants under the CMEC regime. EDP reflected this in the financial statements as at 31 December 2018, through a provision of the same amount. As at 31 December 2023 this provision has been fully utilized (see note 4). 

In their ordinary course of business, EDP Group subsidiaries are involved in several litigations and contingencies (of possible risk) of administrative, civil, tax, labour and other natures. These legal, arbitration or other actions, involve customers, suppliers, employees and administrative authorities. In EDP Group and its legal advisors' opinion, the risk of a loss in these actions is not probable, and the outcome will not affect on a material way its consolidated financial position. The processes whose losses were considered as possible, do not require the recognition of provisions and are periodically reassessed. The detail of possible contingencies is analised as follows: Thousand Euros Group Dec 2023 Dec 2022 Compa Dec 2023 ny Dec 2022 Administrative and Civil 396,009 325,437 330 336 Fiscal 862,930 773,643 10,732 13,321 Other 115,572 125,107 2,791 2,791 1,374,511 1,224,187 13,853 16,448 The events and possible contingencies more relevant in Portugal, are as follows: i) On 29 July 2016, the Portuguese Competition Authority (AdC) has notified EDP S.A. and EDP Comercial, S.A. with a notice for alleged violation of competition laws, regarding the process of the commercial campaign done in partnership with Modelo Continente, designated as "Plano EDP Continente". This was an occasional campaign, limited to two years, which was one of several campaigns usually performed by several other market agents. On 5 May 2017, EDP S.A. and EDP Comercial, S.A. received AdC final decision which applied a fee of 2,900 thousand Euros to EDP S.A. and 25,800 thousand Euros to EDP Comercial. EDP Group is convinced that this campaign has brought real benefits to consumers and competition in markets and that no transgression has been committed. The companies filed their appeal on 19 June 2017 to TCRS. By this court was determined a court hearing that EDP and EDP Comercial would provide security in the amount of 50% of the fine imposed on them by the AdC, and on 19 June 2020, EDP and EDP Comercial provided surety bond and surety in the amounts of 1,450 thousand Euros and 12,900 thousand Euros, respectively. On 30 September 2020, a judgment was issued by the TCRS, which maintained the conviction of the two companies of the EDP Group, as well as Sonae Group's Companies, having also reduced fines by 10%. Fines were determined at 2,610 thousand Euros and 23,220 thousand Euros for EDP and EDP Comercial, respectively. On 30 October 2020, EDP and EDP Comercial appealed the condemnatory sentence handed down by the TCRS, to the Lisbon Court of Appeal. On 6 April 2021, the parties were notified of the judgment handed down by the Court of Appeal of Lisbon, through which it decreed the suspension of the proceedings and the preliminary referral of the case to the Court of Justice of the European Union, under the foreseen mechanism Article 267(b) of the Treaty on the Functioning of the European Union. The case was filed at the Registry of the Court of Justice on 26 May 2021, with written observations having been submitted by the parties on the questions referred by the Lisbon Court of Appeal. Following the oral trial hearing at the Court of Justice of the European Union held on 9 November 2022, EDP and EDP Comercial were notified on 2 March 2023 of the Advocate General's conclusions. The judgment of the Court of Justice of the European Union was delivered on 26 October 2023, following the referral questions raised by the Lisbon Court of Appeal, referring the decision on some of the questions to the latter. On 19 February, the Lisbon Court of Appeal issued a judgment confirming the TCRS's sentence. EDP and EDP Comercial are currently analyzing the aforementioned judgment and the possible forms of reaction;

ii) On 3 September 2018, the Portuguese Competition Authority (AdC) notified EDP Produção with a Statement of Objections, under which EDP Produção is accused of abuse of a dominant position in the secondary regulation band market (a part of the ancillary services market). AdC claims that EDP Produção has deliberately limited the participation of CMEC plants in the secondary regulation market between 2009 and 2014, benefitting its non-CMEC power plants. The alleged benefit, to the detriment of consumers, would be twofold: receiving higher compensation under CMEC annual adjustment regime; profiting from higher market prices in said market. AdC has estimated that the alleged practice of EDP Produção has generated damages to the national electricity system and to consumers of around 140 million Euros. AdC pointed out that the adoption of a Statement of Objections did not determine the result of the investigation, which began in September 2016 and is still in course. On 28 November 2018, EDP Produção presented to AdC its facts about the accusation. On 18 September 2019, AdC has notified EDP Produção of an alleged infraction to competition rules. This contingency was estimated with a value of 48 million Euros and its graduation was assessed as possible (see note 4). On 30 October 2019, EDP Produção presented an appeal against this decision to the TCRS. On 20 May 2020, EDP Produção was notified of a decision by the TCRS, which, among other things, admitted its Judicial Challenge Appeal, establishing a purely return effect and determining the payment of the fine imposed within 20 days. In this regard, EDP Produção submitted requests, invoking supervening facts for the demonstration of considerable damage, and arguing defects in the decision that determined the attribution of a mere devolution effect to the Judicial Challenge Appeal. On 16 July 2020, EDP was notified of an order which implied the existence of substantial losses if the fine was paid in advance. Thus, the payment order was therefore suspended. However, on 12 October 2020, EDP Produção was notified of the appeal filed by the Public Prosecutor's Office, at the Lisbon Court of Appeal, against the TCRS order of 16 July 2020, and considered the existence of considerable damage in the early payment of the fine and suspended the payment order. On 18 November 2020, EDP Produção was notified of a decision by the Lisbon Court of Appeal, granting the appeal presented by the Public Prosecutor and, consequently, revoking the order of TCRS of 16 July 2020. EDP Produção appealed this judgment to the Constitutional Court on 30 November 2020. On 22 February 2021, EDP Produção was notified of the decision of the Constitutional Court in the sense of not knowing the object of the appeal. The case was returned to the TCRS to establish the effect of the appeal filed, to determine whether EDP Produção must pay a fine or provide a guarantee. By order of the same day, the TCRS has scheduled the trial hearing for 27 September, 7, 11 and 25 October, 4, 8, 18, 22 November and 2 and 6 December 2021. On 16 September 2021, the TCRS issued an order that demanded the payment of the fine. Despite having lodged an appeal against this order, on 20 October 2021 EDP Produção paid the amount under appeal, and is waiting for a decision on the appeals submitted. The trial hearing, which began in October 2021, continued with several inquiries until the end of March 2022, with closing arguments taking place on 6 July 2022. On 10 August 2022, the TCRS delivered a judgement, through which it confirmed the conviction of EDP Produção and the imposition of a fine of 48 million Euros, which had already been paid. On 30 September 2022, EDP Produção filed an appeal against the aforementioned decision to the Lisbon Court of Appeal. This was followed by the filing of counter-claims by the AdC and the Public Prosecutor's Office. On 30 June 2023, the trial hearing was held before the Lisbon Court of Appeal. On 25 September 2023, the Lisbon Court of Appeal partially rejected the appeal filed by EDP Produção, confirming the conviction of the TCRS, and also ruled in favor of reducing the fine amount from 48 million Euros to 40 million Euros. On 2 October 2023, EDP Produção filed a request with the Lisbon Court of Appeal to challenge the flaws in the ruling. On 9 October 2023, a request for an appeal was submitted to the Constitutional Court, raising the unconstitutionalities alleged by EDP Produção throughout the process. A decision from the Constitutional Court is awaited on the admissibility of the appeal and notification to present written arguments against the decision of the Lisbon Court of Appeal. By a judgment of 6 December 2023, the Lisbon Court of Appeal rejected the invalidities invoked by EDP Produção and the latter, as a result, on 14 December 2023, submitted a request for clarification of part of the judgment delivered by the Lisbon Court of Appeal. On 22 January 2024, the Lisbon Court of Appeal dismissed EDP Produção's request for correction of the aforementioned judgment delivered on 6 December 2023. On 5 February 2024, EDP Produção filed an appeal with the Constitutional Court against this judgment of the Lisbon Court of Appeal, which dismissed the aforementioned request for clarification of part of the judgment of 6 December 2023. The decisions of the Constitutional Court on the admissibility of the two appeals and the notification to submit written arguments are awaited. Nevertheless, as previously mentioned, in the context of this Proceeding, EDP Produção has already been judicially obliged to pay the fine to which it was sentenced by the AdC even before the judgment and the final decision of the TCRS. Still in the context of this process, on 29 September 2021, EDP Produção was cited in the class action filed by the IUS Omnibus Association based on the alleged abusive behavior of dominant market position in the secondary regulation band market between the beginning of 2009 and the end of 2013, requesting, on behalf of the allegedly harmed consumers, compensation in the amount of 94.8 million Euros, according to one of the estimates of the AdC within the scope of the PRC/2016/05 process. EDP Produção submitted its respective response within the established legal deadline. An order was issued in which the court decided, among other things, to suspend the proceedings until a final decision is made in the administrative offense case no. 309/19.0YUSTR. By judgment of 23 March 2023, adopted following an appeal by EDP Produção, the Lisbon Court of Appeal confirmed the decision to suspend the proceedings. EDP Produção filed a common appeal and an exceptional appeal to the Supreme Court of Justice, which dismissed the appeals by judgment of 15 September 2023.

iii) On 19 July 2021, Celulose Beira Industrial, SA (CELBI), submitted to SU Eletricidade, SA a constitutional request of an Arbitral Tribunal, regarding a conviction of a payment of the energy produced by it under special production in cogeneration, and its interest, since April 2020 (date on which, in accordance with the law and the understanding of DGEG and followed by SU Eletricidade, CELBI has moved to the transitional remuneration scheme provided for in DL No. 23/2010 and Ordinance No. 140/2012), and throughout the term of operation of its Cogeneration Center (which it estimates to be at least 25 years), i.e. at least until 24 March 2035 (supporting this understanding in the fact that the 2002 Remuneration Scheme does not establish any period); or, in the alternative, until 24 March 2030 (claiming that you are entitled to be remunerated under the 2002 Remuneration Scheme for a further 120 months (10 years) from March 2020); or, in the alternative, until November 2020 (claiming that the transition to the 2012 Remuneration Scheme should only take place six months after the effective knowledge of the communication sent by the SRB); or, in the alternative, until August 2020 (in the alternative claiming that the transition from CELBI's remuneration scheme would operate from the beginning of the month following the date of the audit report certifying primary energy savings, which means the transition would operate from August 2020 because the audit report is from July 2020). The overall value of the application amounts to 6,839 thousand Euros and has been classified as possible risk. In October 2021, SU Eletricidade filed a challenge. In February 2022, Procedural Decision No. 1 was issued, by which the Arbitral Tribunal considered itself competent to adjudicate the dispute between the parties, which was challenged by SU Eletricidade through annulment action filed in March 2022, currently pending at the Central Administrative Court, the pleadings phase having elapsed. In April 2022, the preparatory hearing was held, which was intended in particular to discuss previous questions raised as well as to the fixing of the list of the facts not at issue and the themes of the evidence. In June 2022, the parties filed a joint application alleging supervening facts. The trial hearing took place on 13, 14 and 15 September 2022 and, on 5 of December 2022, the parties presented the respective final written arguments. On 30 January 2023, the parties were notified of the arbitral award, which partially upheld one of the claims filed by CELBI (corresponding to 11.75% of them). On 31 March 2023, SU Eletricidade filed an action to annul the arbitral award at the South Administrative Central Court. The possible contingencies more relevant in Brazil, are as follows: i) Investco is involved in a legal action of a civil nature mostly related with indemnity claims resulting from the filling of the hydroelectric reservoir, in the amount of 15,895 thousand Euros (31 December 2022: 23,365 thousand Euros); ii) There is a public civil action filed against EDP São Paulo and EDP Espírito Santo by ADIC – Associação de Defesa dos Interesses Colectivos, claiming a compensation arising from a tariff readjustment on part A from 43 concessionaires. The estimated value attributable to EDP São Paulo and EDP Espirito Santo amounts to 91,618 thousand Euros (31 December 2022: 74,402 thousand Euros); iii) EDP São Paulo is a party to a lawsuit related to the COFINS (Contribution for social security financing) from 1993 to 1995 in joinder with AES Eletropaulo, where is discussed the application of the tax amnesty introduced by the Provisional Measures paragraphs 1858-6 and 1858-8, granted to taxpayers who did not collect COFINS, considering it improper. In the trial of 2nd Instance, was partially confirmed the right to amnesty, and applied the Decree-Law 1,025/69, which established the payment of procedural costs in favour of the National Treasury. From this decision, an appeal was presented, which holds trial. The updated amount as at 31 December 2023 is 15,165 thousand Euros (31 December 2022: 14,058 thousand Euros); iv) EDP São Paulo and EDP Espírito Santo have administrative and judicial actions regarding tax compensations not ratified by the Brazilian Federal Revenue Bureau, which: (i) are protected by judicially recognised credits (IRPJ - Corporate tax income and CSLL - Social Contribution on net profits) and (ii) that result from tax contributions in 2001 of IRPJ, CSLL, PIS (Social integration programme) and COFINS considered to be excessive as a consequence of the application of "Parecer COSIT 26/2002" (Extraordinary Tariff Adjustment - RTE) published by the Brazilian Tax Authorities. According to this opinion, the amounts resulting from tariffs updated under RTE should be recognised and taxed only as of 2002. During 2021 there was a reduction in the amount due to the success obtained in one of the administrative proceedings, cancelling the debt collection. As at 31 December 2023, the updated values amount to 23,158 thousand Euros (31 December 2022: 19,736 thousand Euros); v) Lajeado has a judicial tax action initiated by the Brazilian Tax Authorities in 2014 aimed at collecting tax contributions (IRPJ and CSLL) resulting from the disallowance of expenses regarding goodwill arising from a business combination (acquisition). As at 31 December 2023, this contingency amounts to 12.951 thousand Euros (31 December 2022: 27,388 thousand Euros). In 2023, there was a reduction in the contingency amount, due to a favorable decision that canceled the fine and closed the discussion at the administrative level, in addition to the exclusion of the statutory fine with the related interest and charges, related to the judicial discussion. Currently, the judgment in the judicial sphere is awaited for the remaining amounts.

Finally, even if EDP Group classifies its risk as remote, it is important to identify the following litigation: i) On 27 October 2009 and 5 January 2010, the EDP Group received two tax settlements regarding 2005 and 2006 taxable income for the EDP tax Group, which included an adjustment of 591 million Euros regarding its subsidiary, EDP Internacional SGPS, related to the tax treatment considered by the EDP Group in relation to a capital loss generated with the liquidation of a subsidiary, whose main assets consisted of investments in operating subsidiaries in Brazil, namely EDP Espírito Santo and Enersul. As at 31 December 2023, the amount of this tax contingency amounts to 326 million Euros (31 December 2022: 315 million Euros). Considering the analysis made, the technical advice received and a favourable binding opinion obtained from the tax authorities in relation to the nature of the transaction occurred in the year of the assessment, the EDP Group considers as remote the risk associated with this matter. Under this analysis, the capital loss is tax deductible for income tax purposes as established in article 75 no. 2 of the Corporate Income Tax Code ("Código do IRC") based on the wording of the law in force at that date (existing article 81). Given the above, and considering that the EDP Group’s tax procedures comply with applicable Portuguese tax legislation at the date of the events, the Group is currently using all available legal means to contest these additional settlements. Thus, following the implied rejection of the hierarchical appeal, EDP presented a judicial claim, on 6 June 2012. In November 2018, EDP Group was notified with a decision in favour. The Treasury filed an appeal on that decision. 

38\. Institutional partnerships in North America The caption Institutional partnerships in North America is as follows: Thousand Euros Group Dec 2023 Dec 2022 Deferred income related to benefits provided 769,191 798,363 Liabilities arising from institutional partnerships 1,419,054 1,413,799 2,188,245 2,212,162 Subsidiaries in North America recognises under this caption the receipts of institutional investors associated with wind and solar projects. This liability is reduced by the amount of tax benefits provided and payments made to the institutional investors during the period.

As at 31 December 2023, EDP Group holds contracts for the purchase and sale of commodities traded on futures exchange market, namely Chicago Mercantile Exchange, Intercontinental Exchange, European Energy Exchange and OMIP, whose fair value of the contracted operations is settled on a daily basis, and therefore it is not included in the Statement of Financial Position. The notional of these futures contracts amounts to 3,666,585 thousand Euros with maturities ranged between 2024 and 2033 (31 December 2022: 4,246,301 thousand Euros), and the fair value held in EDP Group results and cash flow hedge reserves related to these operations are a negative amount of 34,388 thousand Euros and a positive amount of 50,263 thousand Euros, respectively (31 December 2022: negative amount of 102,517 thousand Euros and positive amount of 280,621 thousand Euros). The financial risk management of EDP S.A. and other entities of the Group is centrally carried out by EDP S.A., and in terms of commodity price risk management by EDP GEM (notes 5 and 12). On this basis, EDP S.A. and EDP GEM contract derivative financial instruments to hedge individual business risks and those of the EDP Group companies, performing intermediation for these entities in the negotiation and contracting. The fair value of the derivative financial instruments at Company level is as follows: Dec 2023 Dec 2022 Thousand Euros Assets Liabilities Assets Liabilities Cash flow hedge Interest rate swaps \- \- 92,527 -57,498 Swaps related to gas commodity \- \- -187,698 -1,260,430 Electricity swaps \- \- 438,952 -142,417 Currency forwards (includes commodities forwards) \- \- 60,352 8,382 Trading Interest rate swaps 31,371 -30,472 36,637 -35,203 Cross-currency interest rate swaps 124,439 -161,995 165,562 -217,572 Commodity swaps 1,257,441 -1,257,441 3,143,029 -3,186,752 Currency forwards 85,132 -85,117 189,713 -189,713 Commodity forwards 12,888 -12,888 33,618 -92,557 Currency forwards associated to commodities 50,705 -50,705 67,896 -31,872 On an individual basis, the changes that occurred are essentially justified by the transfer of the energy management activity on 1 February 2023 to EDP GEM Portugal, S.A. (see note 13). During the application of hedge accounting with pre-existing derivatives, the value of the Currency forwards associated to commodities has a positive value that corresponds to the variation in the fair value of the instruments since the date of designation, while the contracts as a whole they represent a liability; The asset value of Swaps related to gas commodities has a negative value that corresponds to the change in the fair value of the instruments since the designation date, while the contracts as a whole represent an asset. The fair value of derivative financial instruments is booked in Other debtors and other assets (see note 28) and Other liabilities and other payables (see note 40), according to its nature.

Integrated Annual Report 2023 Financial Statements and Notes 

Fair value of derivative financial instruments is based on listed market prices, whenever available, or on valuations determined through valuation models that use variables observable on the market. Therefore, according to IFRS 13 requirements, the fair value of the derivative financial instruments is classified as of level 2 (see note 46) and no changes of level were made during this period.

46\. Fair value of financial assets and liabilities Fair value of financial instruments is based, whenever available, on listed market prices. Otherwise, fair value is determined through quotations supplied by third parties or through the use of generally accepted valuation models, which are based on cash flow discounting techniques and option valuation models. These models use market data which impacts the financial instruments, namely yield curves, exchange rates and volatility indicators, including credit risk. Market data is available on stock exchanges and/or financial information platforms such as Bloomberg and Reuters. 

The fair value of financial assets and liabilities is as follows: Dec 2023 Dec 2022 Carrying Fair value Difference Carrying Fair value Difference Thousand Euros amount amount Assets Equity instruments at fair value 204,752 204,752 \- 216,418 216,418 \- Investment property 25,344 25,344 \- 27,294 27,294 \- Debtors/other assets from commercial activities 8,543,596 8,543,596 \- 8,660,346 8,660,346 \- Other debtors and other assets Derivative financial instruments 1,117,525 1,117,525 \- 2,575,698 2,575,698 \- Loans to related parties - OW FS 429,098 323,143 -105,955 184,644 138,864 -45,780 Other 1,529,086 1,529,086 \- 2,535,963 2,535,963 \- Collateral deposits/financial debt 70,731 70,731 \- 53,101 53,101 \- Cash and cash equivalents 3,372,432 3,372,432 \- 4,900,205 4,900,205 \- 15,292,564 15,186,609 -105,955 19,153,669 19,107,889 -45,780 Liabilities Financial debt 20,632,691 20,291,137 -341,554 20,022,473 18,938,885 -1,083,588 Trade payables/other liabilities from commercial activities Suppliers and accruals 3,861,352 3,861,352 \- 3,805,467 3,805,467 \- Other 4 054 217 4,054,217 \- 6 011 957 6,011,957 \- Institutional partnerships 2,188,245 2,188,245 \- 2,212,162 2,212,162 \- Other liabilities and other payables Derivative financial instruments 1,871,967 1,871,967 \- 5,753,706 5,753,706 \- Other 2,798,775 2,798,775 \- 3,006,683 3,006,683 \- 35,407,247 35,065,693 -341,554 40,812,448 39,728,860 -1,083,588 

Given that EDP Group’s financial assets and liabilities, recognised at amortised cost, are predominantly short-term, changes in fair value were not considered. Fair value of EDP Group’s financial debt was determined considering current market, namely listed price (level 1). The market value of financial debt, when no listed market prices are available, is calculated based on the discounted cash flows at market interest rates at the balance sheet date, increased by the best estimate, at the same date, of market conditions applicable to Group's debt. Loans to related parties - OW FS regards long-term maturity loans granted to OW FS Offshore, S.A. (see note 28). These loans bear interest at market rates, which are fixed or with reference rate indexed, such as Euribor and SOFR, plus a market spread. Given the long-term maturity, for fixed rate loans fair value has been calculated based on the discounted cash flows at market interest rates at the balance sheet date.

Integrated Annual Report 2023 Financial Statements and Notes 

According to IFRS 13 requirements, EDP Group established the way it obtains the fair value of its financial assets and liabilities. The levels used are defined as follows: Thousand Euros Level 1 Dec 2023 Level 2 Level 3 Level 1 Dec 2022 Level 2 Level 3 Financial assets Equity instruments at fair value through Other comprehensive income (note 23) 14,400 91,610 22,521 24,714 83,062 31,494 Profit or loss (note 23) \- \- 76,221 \- \- 77,148 Tariff deficit at fair value through other comprehensive income (note 27) \- 114,008 \- \- 1,164 \- Amounts receivable from concessions-IFRIC 12 at fair value through profit or loss (note 27) \- 1,365,311 \- \- 1,012,104 \- Investment property (note 24) \- 25,344 \- \- 27,294 \- Derivative financial instruments (note 43) \- 1,117,525 \- \- 2,575,698 \- 14,400 2,713,798 98,742 24,714 3,699,322 108,642 Financial liabilities Derivative financial instruments (note 43) \- 1,871,967 \- \- 5,753,706 \- \- 1,871,967 \- \- 5,753,706 \- The market value of the amounts of tariff deficit at fair value through other comprehensive income is calculated based on the cash flows associated with these assets, discounted at rates which, at the balance sheet date, better reflect the assets risk considering the average term of the assets. The amounts receivable from concessions - IFRIC 12 at fair value through profit or loss are valued based in the methodology of the Value of Replacement as New (VNR). This method requires that each asset is valued, at current prices, for all the expenses needed for its replacement by equivalent asset that performs the same services and has the same capacity as the existing asset. The valuation for each asset is based on (i) Data Bank of Referential Prices - which is defined in the Tariff Adjustment Procedures - PRORET; or (ii) Data Bank of Prices from the Distribution company - which is formed based on the company's own information; or (iii) Referential Budget – that corresponds to the calculation by comparison of market data, relating to other assets with similar characteristics. ANEEL reviews the VNR, through the valuation report of the Regulatory Remuneration Base, every three years for EDP Espírito Santo and every four years for EDP São Paulo, as established in the concession contracts. The market value of investment properties is based on assessments using current market practices: the comparative method, in cases where there is an active and comparable market, the income method, through discounted cash flows and the cost method, which considers the market value of the land and the construction costs. The movement in financial assets and liabilities included in Level 3 is as follows: At fair value through other Thousand Euros comprehen- sive income profit or loss Balance at beginning of period 31,494 77,148 Change in fair value (see note 23) -10,023 -6,516 Acquisitions 1,313 6,849 Disposals -285 -1,300 Other changes 22 40 Balance at the end of the period 22,521 76,221 The assumptions used in the determination of Equity Instruments at Fair Value are described in note 23, as required by IFRS 13.

Under current and future socioeconomic trends and practices followed by the EDP Group regarding to environmental sustainability, the group accounts for provisions to cover the costs of dismantling, decommissioning, restoring and decontaminating land where electric power plants are located, of 71,298 thousand Euros and 101,620 thousand Euros for thermoelectric power plants located in Portugal and Spain, respectively. Regarding the liability to dismantle and restore the land where solar and wind farms are located to its original condition, as at 31 December 2023, the provisions amount to 294,730 thousand Euros. Additionally, the provision to dismantle the Trillo nuclear power plant amounts to 40,161 thousand Euros (see notes 2 n) and 37). 

Environmental income recognised in 2023 relates to the sale of environmental waste of 3,158 thousand Euros (31 December 2022: 7,015 thousand Euros) and the sale of by-products of 2,829 thousand Euros (31 December 2022: 1,101 thousand Euros). EDP’s prioritization of investment in renewable generation started in 2006, through the anticipation of major trends in the energy market and the support to the vision of a society capable of reducing CO2 emissions, by replacing thermal with renewable energy, decentralizing generation, promoting smart grids and energy storage, and encouraging the demand for renewable electricity. More recently, under the recent Updated Strategic Plan 2023-2026, EDP reinforced its ambition even further to reach Net Zero by 2040 by including our Scope 3 emissions in our targets. With a new baseline year set for 2020, EDP aims to reach net-zero greenhouse emissions across the value chain by 2040, with ambitious mid-term targets by 2030. These targets have been approved by SBTi under the Net Zero Standard. Considering the risks related to climate change and the commitments established under the Paris Agreement, EDP Group has decided, since 2019, to achieve science-based targets. The last updated occurred in 2022, with a baseline year set for 2020, EDP aims to reach net-zero emissions across the value chain by 2040, with ambitious mid-term targets by 2030. The overall goal is to reduce 90% of scope 1, 2 and 3 emissions by 2040 vs. 2020 with near term targets by 2030. These targets have been approved by SBTi under the Net Zero Standard, in early 2023\. The reflect of these commitments in terms of its impact on assets, liabilities and profit and loss are explicit in the notes to the EDP consolidated and company financial statements. These climate commitments were recorded in EDP’s Climate Transition Plan, which was approved by a majority of votes (99,73%) in the last General Meetings of shareholders held in April 2023. The proceeds of green bonds, green loans, and sustainability-linked loans contribute substantially to the implementation of EDP’s Climate Transition Plan and to reach our objectives of becoming To be coal-free by 2025, carbon neutral by 2030, and net zero by 2040. In the end of 2023, sustainable finance amounted to €18.5 billion: (1) €11.1 billion in green bonds; (2) €6.7 billion in sustainability-linked loans and (3) 0.7 billions in green loans, which represented 58% of the nominal debt. 361

50\. Investigation process about CMEC and DPH Following the enactment of an EU legislation package regarding the construction of the Internal Energy Market, aimed at, among others, promoting the liberalization of the electricity sector, the existence of long-term Power Purchase Agreements (“Contratos de Produção de Energia” – CAE), and the Portuguese legal framework involving a “single buyer”, ceased to be compatible with EU law. Accordingly, Decree-Law no. 240/2004, of 27 December, was enacted in the context of the liberalization of the Portuguese energy sector, establishing the early termination of the CAEs entered into in 1996 and, at the same time, approving the methodology to be used in accomplishing said termination, as well as the compensation due to energy producers in that respect. This methodology was subjected to the European Commission’s (EC) prior approval, expressed in the Decision concerning State aid N161/2004, which deemed it effective and strictly necessary. Additionally, the enactment of the aforementioned Decree-Law by the Portuguese Government was object of a legislative authorization, granted by the Portuguese Parliament. In that context, and according to the approved methodology, EDP and REN - Rede Eléctrica Nacional, S.A. (REN) signed the CAE early termination agreements in 2005, their entry into force having taken place on 1 July 2007, after being amended earlier that same year. Both termination agreements were ratified by the member of the Portuguese Government responsible for the energy sector. Pursuant to the provisions of the 2005 CAE termination agreements, on 8 March 2008 the Portuguese Government, REN and EDP Produção entered into a number of concession agreements formalizing EDP’s right of use over the Public Hydro Domain (“Domínio Público Hídrico” – DPH) until the end of the operational life of the hydroelectric plants subject to the so-called Costs for the Maintenance of the Contractual Balance mechanism (“Custos de Manutenção do Equilíbrio Contratual“ – CMEC). Decree-Law 226-A/2007, of 31 May, introduced a new obligation to EDP, unforeseen in the 2004 legislation or in the 2005 termination agreements, which consisted in the payment by EDP of an amount concerning the “economic and financial balance” of each power plant. Pursuant to this legal framework, and following assessments carried out by two independent financial institutions appointed by the Government, EDP Produção was ordered to pay EUR 759 million, as consideration for the extension of its right of use over the DPH. This included approximately EUR 55 million due for the Hydro Resources Tax. In 2012, the EC and Portuguese authorities (the Central Department of Criminal Investigation and Prosecution, a part of the Public Prosecutor’s Office – “Departamento Central de Investigação e Ação Penal”, DCIAP) received complaints regarding (i) the methodology adopted for the early termination of the CAEs and the implementation of the CMEC mechanism and; (ii) EDP’s right of use over the DPH.

So far as the complaint received by the EC is concerned, this institution addressed a clarification request to the Portuguese Government over the early termination of the CAEs, and its replacement by the CMEC framework. The EC decided, in September 2013, that the compensation attributed to EDP Produção in the context of the early termination of the CAEs did not exceed the amount required to reimburse the investment costs meant to be recovered throughout the operational life of the assets in question. Furthermore, it certified that the execution of the CMEC framework respected the terms that were notified to the EC, and approved, in 2004\. Accordingly, the EC has at this stage concluded its investigation regarding the early termination of the CAEs. Having found no evidence of non-compliance with the framework in force in Portugal (approved by the EC itself in 2004) or at the EU level, it decided not to pursue an in- depth investigation on the matter. Simultaneously, in September 2013, the EC decided to undertake an in-depth investigation exclusively in respect of the right of use over the DPH matter. These in-depth investigation proceedings over EDP’s right of use over the DPH were formally concluded in May 2017, with the EC having decided that the consideration paid by EDP was in line with market conditions. It further concluded that the financial methodology followed to determine the price to be paid by EDP for the right of use over the DPH was appropriate and resulted in a fair market price, expressly adding that the accusations that such price (759 million euros) had been underappreciated were baseless, and resulted from an inaccurate financial calculation methodology. In 2 June 2017, EDP was made aware of the investigation being carried out by the DCIAP since 2012 regarding the amounts due to EDP for the early termination of the CAEs and the right of use over the DPH. On that date, the authorities carried out a search in EDP’s offices, as well as REN’s (as network operator) and a consultant. At that time, DCIAP informed, by way of a public press release, that investigations were ongoing, and the alleged facts could amount to active and passive corruption, and economic participation in business deals. The DCIAP further informed, in said press release, that some members of EDP’s Executive Board of Directors, as well as former directors who executed the relevant agreements, were suspects in that investigation. On 6 July 2020, a measure of constraint to suspend the exercise of functions in EDP’s Executive Board of Directors was proposed by the Public Prosecutor’s Office, and applied by the court, to António Mexia and João Manso Neto (then Chairman and member of the board, respectively), while the investigation remained in the inquiry stage. On the same day, the General and Supervisory Board and the Executive Board of Directors resolved to appoint then Chief Financial Officer Miguel Stilwell de Andrade as interim Chairman, for the duration of the impediment of the current Chairman of the Executive Board of Directors, in addition to his functions at the time. On 13 July 2020, and as in due course disclosed to the market (https://www.edp.com/sites/default/files/2020- 07/20200713_Notifica%C3%A7%C3%A3o%20do%20DCIAP_EN_0.pdf ), EDP was notified by the Portuguese Authorities to appoint a legal representative to appear at the DCIAP for questioning and constitution of EDP as defendant, for the facts related to the hiring by EDP Group of the father of the then Secretary of State Artur Trindade. Such diligence has already occurred and EDP was named as a defendant in the context of such judicial procedure and is now waiting for further developments of the procedure. On 30 November 2020, and as communicated to the market on that same date, EDP received formal notices of both suspended members of the Executive Board of Directors, informing of their unavailability to be re-appointed to serve in EDP’s corporate bodies for the 2021-2023 term of office. On 19 January 2021, an Extraordinary General Shareholders’ Meeting was held, and a new management team was appointed to the Executive Board of Directors, for the 2021-2023 triennium. EDP reaffirms that no irregularities exist regarding the matters at hand and believes the amounts due by the early termination of the CAEs and the proceedings regarding the DPH, in particular the amounts paid, were fair and according to market conditions. EDP remains determined in the pursuit of its corporate purpose and in the fulfilment of its clients, shareholders, employees, and remaining stakeholders’ highest expectations. EDP is committed to the accomplishment of its strategic goals, and no impact to its consolidated financial statements is expected to arise as a consequence of the above. Regarding the judicial procedure, it is still under investigation and till the present date there are no relevant developments regarding the reason that uphold EDP as a defendant.

390 Part III Integrated Annual Report 2023 Corporate Governance Report PART I Information on Ownership Structure, Organisation and Corporate Governance A. Ownership Structure I. Capital Structure 1\.

(Company or EDP) is of €4,184,021,624 and is fully paid up, according to Article 4 of EDP's Articles of Association, being represented by 4,184,021,624 ordinary shares, which have a face value of 1 Euro each. The geographical and investor type breakdown of the EDP shareholder structure on 31 December 2023 was as follows: Source: Interbolsa 2\.

391 Part III Integrated Annual Report 2023 Corporate Governance Report 4\. Change of company control EDP has not entered into any significant agreements that come into force, are amended or terminate in the event of a change in control of the Company following a takeover bid, except for normal market practice in terms of debt issuance. In fact, EDP is usually a party in financing agreements and issuer of bonds that include change of control clauses, which are typical set forth in such agreements and securities and are necessary for the completion of transactions, not considering that its existence is likely to harm the economic interest in the transfer of EDP shares, nor the free assessment by shareholders of the directors' performance. In addition, with regard to any measures adopted that determine payments or the assumption of charges by the Company in the event of a change in the composition of the management body, apart from the situations set out in the Remuneration Report, there are no contracts in force at EDP that provide for payments in the event of dismissal or termination by agreement of the duties of a director, nor any other measures that determine the assumption of charges by EDP in the event of a change in the composition of the management body. 5\. Defensive measures EDP has not taken any measures to prevent takeover bids that would put the interests of the Company and its shareholders at risk. The supplementary rules on this matter remain thus in force. In this regard, it is important to note that, pursuant to Article 14 (3) of EDP's current Articles of Association, votes cast by a shareholder on his own behalf or representing another will not be considered if they exceed 25% of all the votes corresponding to the share capital. Although EDP's Articles of Association impose this limitation on the exercise of voting rights, this limitation is not a measure to prevent successful takeover bids. In fact, the inability of the limitation on voting rights to prevent the success of a takeover bid is the result of EDP's current capital structure and of the compliance of the deliberative quorum of two-thirds of the votes cast, which is set out in EDP's Articles of Association for an amendment to the company agreement on this matter with Article 182 - A (2) of the Portuguese Securities Code. No defensive measures have been taken aimed at or resulting in serious erosion of EDP's assets in the event of transfer of control of the company or a change in the composition of the Executive Board of Directors, thereby prejudicing the free transferability of the shares and free appraisal by the shareholders of the performance of the members of the Executive Board of Directors. 6\. Shareholder agreements According to the Article 7 of EDP's Articles of Association, shareholder agreements regarding the Company must be communicated in full to the Executive Board of Directors and the General and Supervisory Board by the shareholders that have signed them in the 30 (thirty) days following their conclusion. According to information provided to the Company by the shareholders, the Executive Board of Directors is aware of the existence of a single shareholder agreement, which was entered into on 11 April 2007 by Parpública, Caixa Geral de Depósitos, S.A. ("CGD") and Société Nationale pour la Recherche, la Production, Le Transport, La Transformation et la Commercialisation des Hydrocarbures ("Sonatrach"). Although Parpública has sold its shareholdings in EDP's share capital and CGD and Sonatrach do not own a qualifying shareholding in EDP's share capital, according to information at EDP's disposal this does not represent automatic cessation of the effects of the shareholder agreement. EDP has not been informed of any agreement to revoke or amend the said shareholder agreement. In 2021, EDP and Sonatrach agreed to terminate the partnership entered into in 2007, under which EDP assumed full control of the combined cycle natural gas plant, Soto 4, in Spain, with an installed capacity of 426MW, through the acquisition of 25% stake held by Sonatrach, and terminates the commercial relations with Sonatrach that were associated with this partnership. II. Shareholdings and Bonds Owned 7\. Qualifying holdings Pursuant to Article 29-H of Portuguese Securities Code, we are providing the following information on qualifying holdings owned by EDP shareholders as at 31 December 2023 and attributable voting rights in accordance with Article 20 (1) of the Portuguese Securities Code.

Special powers of the managing body with regard to decisions to increase share capital The Executive Board of Directors has the powers enshrined in the law and Articles of Association to perform its duties, which are indicated in detail in item 21. In what concerns the approval of decisions on share capital increases, and according to Article 4 (3) of the Articles of Association, the Executive Board of Directors has the power to approve one or more share capital increases up to an aggregate limit of 10% of the current share capital via the issuance of shares to be subscribed by new entries in cash, in accordance with the issuance terms and conditions that it defines. The draft decision must be submitted to the General and Supervisory Board subject to a two-thirds voting majority of the respective members. By resolution of the General Shareholders’ Meeting of 14 April 2021, an autonomous author- isation was introduced in Article 4(4) of the Articles of Association, granting the Executive Board of Directors the possibility of increasing the share capital, one or more times, by an amount corresponding to a maximum of 10% of the share capital at that date (not cumula- tive with the limit of the authorisation provided for in Article 4(3) of the Articles of Association). This gives the company the flexibility to benefit from favourable market con- ditions for a capital increase at any given time; Under this authorisation, the market was informed on 3 March 2023, that the Executive Board of Directors concluded the accelerated bookbuilding process and approved the in- crease in EDP's share capital from €3,965,681,012 to €4,184,021,624, through the issue of 218,340,612 shares at a unit price of €4.58. This share capital increase without sharehold- ers' pre-emptive rights was registered with the Commercial Registry Office on 3 March 

398 Part III Integrated Annual Report 2023 Corporate Governance Report 2023\. The respective shares were placed with certain investors in accordance with an ac- celerated bookbuilding process, also concluded on 3 March 2023. In this context, pursuant to article 4(3) and (4) of EDP's Articles of Association, the General Meeting held on 12 April 2023 resolved to renew the authorisation granted to the Executive Board of Directors to: (i) increase EDP's share capital by up to 10% of the current share cap- ital through the issue of shares to be subscribed by new cash contributions, on one or more occasions, for a period of 5 years from the date of the General Meeting, under terms and conditions to be defined, subject to prior approval by the General and Supervisory Board by a two-thirds majority, allowing, in particular, to resolve under the provisions of Article 6(2) of the Articles of Association, the issue of ordinary shares or securities convertible into or exchangeable for shares representing EDP's share capital and (ii) increase the share cap- ital, one or more times, until 14 April 2026, by an amount corresponding to a maximum of 10% of the current share capital, through the issue of shares, to be paid up in cash and sub- scribed by qualified investors using accelerated bookbuilding procedure(s), in accordance with the terms and conditions of the issue defined by it, provided that the issue price is not less than (a) 95 per cent of the weighted average share price on Euronext Lisbon on the date the price is set, or (b) 95 per cent of the weighted average share price on Euronext Lis- bon in the maximum period of ten days ending on the said date the price is set, and the resolution proposal must be submitted for prior approval by the General and Supervisory Board by a two-thirds majority. It should be noted that, under the provisions of Article 4(5) of EDP's Articles of Association, the authorisations granted to the Executive Board of Directors under the terms of para- graphs 3 and 4 of the said article are not cumulative, in the sense that any shares issued under one of these authorisations will be subject to the maximum limit of the other, and that, therefore, in the use of either or both authorisations, the Executive Board of Directors may not approve share capital increases that exceed 10% of the current share capital. During the aforementioned 2023 General Shareholders’ Meeting, it was also decided to suppress shareholders' pre-emptive rights in capital increases to be decided by the Exec- utive Board of Directors in EDP capital increase(s) carried out through accelerated bookbuild procedures until 14 April 2026 and with a maximum limit of 10% of the current share capital, as provided for in Article 4(4) of the Articles of Association (not cumulative with the limit of the authorisation provided for in Article 4(3) of the Articles of Association). 10\. Significant business relationships between owners of qualifying holdings and the Company In pursuit of its activity and regardless of its relevance, EDP conducts business with and enters into transactions under normal market conditions for similar operations with several entities, beyond which are included qualified shareholders of EDP or companies related to those. Thus, with reference to the 2023 exercise, it should be pointed out the performance of the following operations between companies of EDP Group and owners of qualifying holdings in EDP’s share capital: • The EDP Group, through EDP Clientes, S.A., provided electricity and gas supply services as well as the installation of solar panels to Cementos Tutela Veguín, totalling approxi- mately 50.1 million euros (Cementos Tutela Veguín is a subsidiary of the Masaveu Group, which in turn owns 55.9% of Oppidum Capital, S.L.); • Additionally, the EDP Group, through the company EDP Comercial - Comercialização de Energia, S.A., agreed with the company Exus Management Partners to supply equip- ment and carry out work relating to the interconnection of two photovoltaic plants to the Public Service Electricity Grid, worth approximately 1.7 million euros (Exus Management Partners is a subsidiary of the Masaveu Group, which in turn owns 55.9% of the com- pany Oppidum Capital, S.L); • As disclosed to the market on 27 October 2023, EDP España, S.A.U. entered into a part- nership with Corporación Masaveu, S.A. through the sale of a 50% stake in the Aboño power plant, reflecting an enterprise value of around 350 million euros and an equity value of 60 million euros for 100% of the asset (Corporación Masaveu is a subsidiary of the Masaveu Group, which in turn owns 55.9% of the company Oppidum Capital, S.L); • As disclosed to the market on 29 December 2023, EDP, through its subsidiary EDP Ren- ováveis, S.A., agreed to buy the respective minority stakes of 49% in wind portfolios in Portugal, Poland, and Italy, for a total amount of 0.57 billion euros; • As disclosed to the market on 29 December 2023, EDP signed a sale and purchase agreement for a 50% stake in Energia Asia Consultoria, Lda. with China Three Gorges for a total expected consideration of around 100 million euros, subject to adjustments until the transaction is finalised. 

399 Part III Integrated Annual Report 2023 Corporate Governance Report As for the surrounding governance guidelines, on July 29, 2010, the General and Supervisory Board approved the first version of the “Regulation on Conflicts of Interest and Transactions with Related Parties”, which was subject to review during 2015. On 17 May 2010, the Executive Board of Directors approved the rules on identification, in-house reporting and procedure in the event of conflicts of interest applicable to all EDP Group employees who play a decisive role in transactions with related parties. In the Company’s constant quest to adopt best practices, it has been promoting the revision of internal regulations governing conflicts of interest and business between related parties, and in May 2023 the latest update of the Policy on Transactions with Related Parties came into force, and is available for consultation at EDP’s website Transactions with Related Parties Policy | edp.com. The General and Supervisory Board noted that regarding 2023, in view of the cases analysed and the information provided by the Executive Board of Directors, that no evidence was found that the potential conflicts of interest underlying the transactions made by EDP may have been settled contrary to the interests of the Company. The Financial Matters Committee/Audit Committee is responsible for supervising enforcement of the aforementioned policy and reports on its work to the General and Supervisory Board.

B) Exercise of Voting Rights 12\. Restrictions on Voting Rights Pursuant to Article 14 (2) of EDP's Articles of Association, each share corresponds to one vote. The Company does not issue shares with special plural voting rights. According to Article 14 (9) of EDP’s Articles of Association, the holders of rights representing shares under ADR (American Depositary Receipt) programs may instruct the respective depositary bank in order to see their voting rights exercised or, alternatively, grant proxy to a representative designated by EDP for such purpose, in compliance with applicable legal or statutory provisions; the depository contract should regulate terms and ways for exercising the voting rights, as well as for cases in which such instructions do not exist. According to Article 14 (10) of the Articles of Association, EDP's shareholders can only participate and vote at the General Meeting, personally or through a representative, if on the date of registration, 00:00 hours (GMT) of the fifth day of trading prior to that of the General Meeting, it owns shares corresponding to, under the Law and the Articles of Association, at least one vote.

401 Part III Integrated Annual Report 2023 Corporate Governance Report EDP shareholders may exercise their right to vote by correspondence, postal or electronic, on each of the items on the agenda by means of a communication addressed to the Chairman of the Board of the General Meeting, as provided for in number 6 and number 11 of article 14 of the Articles of Association.

Shareholders can find the necessary forms for postal or electronic votes at EDP's website . EDP has taken several measures to encourage shareholders to exercise their voting rights, such as elimination of financial obstacles that may affect their exercise. These measures include: • general circulation of the notice of meeting of the General Meeting with an express indication of the channels available for the exercise of voting rights and in publications at CMVM website and EDP’s website, in the Justice Ministry and in the Interbolsa Platform (My Interbolsa) and in the NYSE Euronext Lisbon newsletter; • payment of the costs of issuing declarations of ownership of shares for all shareholders who participate in the General Meeting. As per EDP’s Articles of Association, votes cast by a shareholder in his own name or as a representative of another exceeding 25% (twenty-five percent) of all the votes representing the share capital are not considered. This limitation applies to all decisions of the General Meeting, including those for which the law or EDP's Articles of Association provide for a qualified majority of the Company's share capital. Pursuant to Article 14 (4) of EDP’s Articles of Association, votes for which, under Article 20 (1) of the Securities Code or any legal rule that amends or replaces it, he is responsible will be considered cast by the same shareholder. Pursuant to Article 15 (2) and (3) of the Articles of Association, EDP's shareholders are obliged to provide the Executive Board of Directors, in writing and in a complete, objective, clear, truthful form, and in a manner acceptable to the board, all information that it requests from them on facts concerning them and related to Article 20 (1) of the Securities Code. Noncompliance with this obligation shall result in prevention of the exercise of voting rights pertaining to the shares owned by the shareholder in question. If the limitation on the counting of votes affects a number of shareholders, it will operate in proportion to the ordinary shares owned by each one (Article 14 (5) of the Articles of Association). Furthermore, pursuant to Article 20 (1) of the Portuguese Securities Code, or any legal rule that amends or replaces it, shareholders who become owners of a shareholding of 5% (five percent) or more of the voting rights or share capital, must inform the Executive Board of Directors thereof within five business days of the date on which ownership occurred. They cannot exercise their voting rights until they have made this communication (Article 15 (1) of EDP's Articles of Association). 13\. Maximum percentage of voting rights that can be exercised by a single shareholder or shareholders that are related in some of the relations of Article 20 (1) See item 12. 14\. Decisions of shareholders who, under the Articles of Association, can only be made by a qualified majority other than those provided for by law Decisions by the General Meeting are taken by a majority of votes cast, unless the law or the Articles of Association require a qualified majority (Article 11 (3) of the Articles of Association). Article 10 (1) of the Articles of Association defines the performance of functions in any corporate body is incompatible with: • the status of a legal person that is a competitor of EDP or a company in a control or group relation with EDP; • the status of a legal person or an individual related to a legal person that is a competitor of EDP; • the exercise of functions, of any nature or for any reason whatsoever, notably by appointment to a corporate office, by employment contract or by services provision agreement, at a legal person that is a competitor of EDP or at a legal person related to a legal person that is a competitor of EDP; • the appointment, even if only in fact, for a corporate body member by a competing legal person or a person, natural or legal, related to a legal person competing with EDP. Nevertheless, Article 10 (4) defines that the incompatibilities set forth in the foregoing paragraphs may also not apply to the performance of functions as a member of the general 

402 Part III Integrated Annual Report 2023 Corporate Governance Report and supervisory board, to the extent permitted by law, subject to authorization given by prior resolution, with the favour of two thirds of the votes cast at the elective general shareholders’ meeting. The competition relation must be expressly referred to and precisely identified in the appointment proposal, and the authorization resolution may be subject to conditions, notably to a holding of no more than 10% of EDP’s share capital. It should also be highlighted that, according to Article 10 (10) of EDP’s Articles of Association, it should not be deemed to be a competitor of EDP the legal person shareholder that individually holds at least 20% of the share capital of EDP, and that, directly or through a legal person which is in a domain relationship with it, enters into and maintains a medium or long term strategic partnership of business cooperation in the activities of generation, distribution or supply of electricity or natural gas, approved in accordance with legal and statutory provisions, with prior favourable opinion of the General and Supervisory Board. In all other cases, the deliberative quorum set out in Article 383 (2) of the Portuguese Companies Code applies. II. Management and Supervision A) Composition 15\. Corporate governance model EDP's governance structure is a dual model one and consists of the General Meeting, Executive Board of Directors, General and Supervisory Board and the Statutory Auditor. The separation of management and supervision roles is embodied in an Executive Board of Directors, which is responsible for the management of the Company’s business, and a General and Supervisory Board, the highest supervisory body. The division of competences, inherent to such model, between the Executive Board of Directors and the General and Supervisory Board, has been assuring an effective management of the Company, benefitted by a constant and attentive supervision. The dual model of corporate governance in place at EDP since July 2006 has allowed for an effective separation of the Company’s supervision and management in pursuit of the goals and interests of EDP and its shareholders, employees, and other stakeholders, thereby contributing to achieving the degree of trust and transparency necessary for its adequate functioning and optimization. It is also important to note that this governance model has proven to be adequate to the size and shareholder structure of the Company, allowing for constant supervision both by the reference shareholders and by the independent members, through the respective intervention in the General and Supervisory Board. Considering the transversal competences of the General and Supervisory Board and the specificities of the activities of the four Specialized Committees, the integration of members of the General and Supervisory Board and of the Executive Board of Directors of EDP should, according to the Selection Procedure of the members of the General and Supervisory Board and of the Executive Board of Directors, ensure diverse skills, professional experiences, diversity of knowledge, gender and cultures, taking into account the specificities of the Company's business. Along with the concern for the individual adequacy of each member, it is also sought that the composition of the governing bodies and corporate bodies demonstrate a collective adequacy, bringing together the professional and personal skills necessary for the proper performance of the functions of each body of EDP. Likewise, in determining the respective number of members, the size of the Company, the complexity of its activity and its geographical dispersion are considered, in addition to the costs and the desirable speed of operation of the administration. According to Article 11 (2) (b) of the Articles of Association, it is the responsibility of the General Meeting of EDP to elect and dismiss the members of the Executive Board of Directors and the General and Supervisory Board, as well as their Chairmen and Vice- Chairmen, if any, and the Statutory Auditors, based on a proposal by the General and Supervisory Board (or by delegation to the Financial Matters Committee/Audit Committee). The General Meeting also appoints the members of the Environment and Sustainability Board, on proposal of the Executive Board of Directors, and Remuneration Committee of the General Meeting. For a better understanding of EDP's corporate governance, EDP's website allows shareholders and the general public to view the up-to-date Articles of Association in Portuguese and English, the Internal Regulation of the Executive Board of Directors, General and Supervisory Board and its committees, documents that have been modified in order to accommodate best practices, notably the principles and recommendations set forth by the Corporate Governance Code issued by the Portuguese Institute for Corporate Governance. Worth noting also that EDP has since 2010 a Corporate Governance Manual, whose primary objective consists of registering and sharing the provisions of the Executive Board of Directors and of General and Supervisory Board regarding best practices recommendations applicable to EDP on corporate governance. The Manual has a dynamic nature. It should therefore continue to be revised periodically, considering the contributions of all interested parties in the continuous development of EDP’s governance model. 

403 Part III Integrated Annual Report 2023 Corporate Governance Report The Manual for the Corporate Governance of EDP is available to shareholders and general public at its website: Corporate Governance Manual | edp.com. In what concerns prevention and fighting against harassment at work, and complementing the commitments already taken on by EDP in its Code of Ethics, available at EDP’s website, the Good Conduct Code for the Prevention and Fight Against Harassment at Work entered into force as of 21 November 2017 and it is applicable to all EDP Group’s employees. According to this Code, other service providers and suppliers are explicitly required to uphold or adhere to the principles established, in accordance with their obligations under qualification procedures or current contracts. In this regard, during 2022, a new channel for reporting complaints was created, available at EDP's website - Speak Up EDP Channel\- and on the other websites of the applicable EDP Group companies. Additionally, the Integrity Policy approved by the Executive Board of Directors has implemented the mandatory execution to all EDP Group companies as well as to its employees, service providers acting on its behalf, in strict compliance with the legal framework applicable in geographies where the Group is present which aim to avoid unlawful conducts, in particular those associated with the practice of corruption acts, money laundering and terrorism financing. EDP Group is committed to promote an exempt, honest, integrated, professional, and fair action and requires that its employees and contracted third parties behave in accordance with such commitment, complying with the legislation and regulation in force. The EDP Group Companies has implemented and has disseminated prevention, detection, and control measures towards any form of corruption, prevarication, conduct on conflict of interest, influence peddling, money laundering, terrorism financing and other illegal acts. In this regard, the EDP Group Companies may adopt more demanding additional measures, according to local needs, always ensuring the compliance with the local applicable legislation. Additionally, the Compliance & Internal Control which independence is guaranteed through the reporting to the Executive Board of Directors and to the General and Supervisory Board/Financial Matters Committee/Audit Committee of EDP is responsible to biennially review this Policy or whenever any relevant legislative change occurs, submitting those amendments to the Executive Board of Directors for approval. The Integrity Policy of EDP Group was revised in 2023 and is available at EDP’s website: EDP Integrity Policy | edp.com. EDP intends to continue to assume a precursor and excellence role about the promotion of best government practices, in the hope that this initiative may also contribute to enrich the debate on these matters in the general context of the organization and functioning of public limited companies, particularly in Portugal. 16\. Articles of Association rules on procedural and material requirements for the appointment and replacement of members of the Executive Board of Directors and General and Supervisory Board It is the role of the General Meeting to elect and remove members of the Executive Board of Directors and the General and Supervisory Board, including their chairmen.

In the event of permanent absence of any of the members of the General and Supervisory Board, the substitutes on the list submitted to the General Meeting must be summoned by the Chairman of this Board to replace him/her, following the order on the list. Pursuant to Article 21 (5) of EDP's Articles of Association, the substitutes on the list must all be independent. If there are no substitutes, they will be elected by the General Shareholders’ Meeting. 17\. Composition of the Board of Directors, Executive Board of Directors and General and Supervisory Board The shareholders elected, at the Extraordinary General Shareholders’ Meeting held on 19 January 2021, the members of the Executive Board of Directors for the three-year mandate 2021-2023.

Independent members of the Executive Board of Directors and General and Supervisory Board EDP's Articles of Association (Article 9 (1), Article 10 (1), Article 11 (2) (d), Article 21 (4), Article 22 (1) (a), Article 23 and Article 27) and the Internal Regulation of the General and Supervisory Board (Article 8), both available on its website: Articles of Association and Internal Regulation of the General and Supervisory Board, lay down the rules on independence and incompatibilities for members of any of the Company's corporate bodies. The criteria of independence set out in EDP's Articles of Association are in line with those laid down in 414 (5) of the Companies Code and determine that independence means an absence of direct or indirect relations with the Company or one of its bodies and an absence of any circumstances that might affect impartiality of analyses or decisions, e.g. because the people in question own or are acting on behalf of owners of a qualifying shareholding of 2% (two percent) or more of the share capital of EDP or have been re- elected for more than two terms of office continuously or intermittently. Pursuant to Article 9 (1) of EDP's Articles of Association, independence is “absence of direct or indirect relations with the Company or one of its bodies and an absence of any circumstances that might affect impartiality of analyses or decisions, e.g., because the people in question own or are acting on behalf of owners of a qualifying shareholding of 2% (two percent) or more of the share capital of EDP or have been re-elected for more than two continuous or intermittent mandates". In view of the need to clarify the aforementioned Article 414 (5) of the Company Code, as there are diverging legal opinions, Associação de Emitentes de Valores Cotados em Mercado (“AEM”) requested an opinion from the CMVM , whose opinion was that the capacity as independent is only lost if, “on the basis of the criterion of number of terms of office, in a situation likely to affect his/her impartiality in analyses or decisions if the members of the supervisory bodies of public limited companies, having been elected for a first term of office and re-elected continuously or intermittently for a second and third term, are re-elected (for the third time, therefore) for a fourth term of office.” Pursuant to its Internal Regulation, the General and Supervisory Board has in place a specific procedure regarding compliance with a large number of rules on incompatibilities and independence applicable to positions on this board (Articles 7 and 8 of the General and Supervisory Board Internal Regulation). This procedure includes the following aspects: • acceptance of a position as member of the General and Supervisory Board is subject to a written statement setting out specifically (i) the inexistence of any incompatibility under the law or Articles of Association; (ii) compliance with the independence requirements set out in its Internal Regulation, if the person has been elected as an independent member; (iii) the members' obligation to report to the Chairman of the General and Supervisory Board or, for the Chairman, directly to the board any subsequent event that might generate incompatibility or loss of independence; 

407 Part III Integrated Annual Report 2023 Corporate Governance Report • every year, the members of the General and Supervisory Board must renew their statements as to the inexistence of incompatibility and, if applicable, the compliance with the independence requirements. Also, every year, the General and Supervisory Board conducts a general assessment of compliance with the rules of incompatibility and independence by its members. At the same time, the Internal Regulation of the General and Supervisory Board (article 8) has broadened the independence criteria applicable to its members, going beyond the provisions of Article 414 (5) of the Companies Code and Article 9 of EDP's Articles of Association, and so people who directly or through their spouse or relative or similar in a straight line and to the collateral third degree, inclusive, are in one of the following situations cannot have independent status: • being holder, director, having contractual ties or acting on behalf or on the account of owners of a qualifying shareholding of 2% (two percent) or more of the share capital or voting rights in EDP or the same percentage in a company of which it is a subsidiary; • being a holder, director, having contractual ties or acting on behalf or on the account of owners of a qualifying shareholding of 2% (two percent) or more of the share capital or voting rights in a company that is a competitor of EDP; • having been re-elected for more than two consecutive or non-consecutive terms of office; • having exercised for twelve years, on a consecutive or non-consecutive basis, functions in any corporate body of the Company exception made to, from the end of its functions in any body and its new appointment, at least a three-year period has elapsed; • having, in the last three years, provided services or had a significant commercial relation with the Company or one of its Subsidiaries; and, • being a remuneration beneficiary paid by the Company or one of its Subsidiaries other than the remuneration deriving from the execution of its functions as a member of the General and Supervisory Board. The rules of independence covering members of the General and Supervisory Board are particularly important regarding the following requirements: • the board must consist of a majority of independent members (Article 434 (4) and Article 414 (5) and (6) of the Companies Code and Article 21 (4) of EDP's Articles of Association); • the Financial Matters Committee/Audit Committee is composed, at least by, three independent members of the General and Supervisory Board (Article 23 (2) of EDP Articles of Association and Article 3 (1) of the Financial Matters Committee/Audit Committee’s Internal Regulation); • the Remuneration Committee of the General and Supervisory Board must comprise a majority of independent members (Article 27 (1) of the Articles of Association and Article 28 (b) of the General and Supervisory Board's Internal Regulation); • the United States of America (USA) Business Affairs Monitoring Committee must be composed mainly of independent members (Article 3 (1) of the Internal Regulation of the Business Monitoring Committee in the United States of America); • the Corporate Governance and Sustainability Committee must be composed mainly of independent members (Article 3 (1) of the Internal Regulation of the Corporate Governance and Sustainability Committee. In compliance with the above procedure, at the start of their terms of office, the members of the General and Supervisory Board stated that they were not in any of the situations of incompatibility set out in the Companies Code (Article 414-A (1) (a) to (e), (g) and (h) (ex vi Article 434 (4)) and Article 437 (1)) or under Article 10 (1) of the Articles of Association and, where applicable, that they complied with the independence requirements of the Internal Regulation of the General and Supervisory Board and the Articles of Association of EDP (article 9 (1), article 11 (2) (d) and article 21 (4)) . Of the incompatibility situations for the exercise of the role of member of the General and Supervisory Board, pursuant to the Article 414-A of the Companies’ Code, it is considered the exercise of functions of administration or supervisory in five companies. Therefore, one may not be elected or designated a member of the General and Supervisory Board if holds office of administrator or supervisor in five companies. At the end of 2023, the members of the General and Supervisory Board renewed their statements on incompatibilities and on independence. The above statements are available to the public at EDP's website at General and Supervisory Board Incompatibility Statements. The independent members of the General and Supervisory Board are shown in the chart in Item 17 above.

430 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance II. Whistleblowing 49\. Whistleblowing policy and channels The EDP Group has long pursued principles of trust and transparency regarding the way it develops its activity and relates to all its stakeholders, making its options clear in this matter, both through the Code of Ethics, created in 2005, and through the Integrity Policy. These principles of trust and transparency naturally includes channels for reporting alleged unethical and/or illegal behaviour, which all stakeholders can use whenever they consider that the company's ethical and integrity principles may be at risk. In 2022, following the entry into force of Law no. 93/2021, of December 20, which transposed Directive (EU) 2019/1937 of the European Parliament and of the Council, of October 23, 2019, on the protection of persons who report violations of European Union law, and which established the legal obligation to define and implement a reporting channel for any legal person that has 50 or more employees, or who carry out certain activities provided for in the aforementioned Directive, EDP reviewed and updated the channels previously made available, its complaint management process, the procedures resulting from it and the technological support for the reporting channels. In compliance with the new legislation, specific reporting channels were also created (hereinafter “Speak Up” Channels) for each obliged EDP Group company. In this context, the previously existing EDP Ethics channels and the channel for communication of irregularities to the Financial Matters Committee/Audit Committee (FMC/AUDC) of the General and Supervisory Board, were consolidated in the new EDP “Speak up” channel. In this sense, in 2023, 38 (thirty-eight) complaints (in Portugal and Spain) were analysed and closed by the EDP Ethics Committee, of which 31 (thirty one) reported in 2023 and 7 (seven) carried over from 2022. It should be noted that 9 (nine) complaints, out of a total of 40 (forty) reported in 2023, were carried over to 2024. Of the complaints received by EDP's Ethics Committee in 2023, the most reported types were "Employee", "Employee Welfare", "Corruption and Bribery" and "Personal Data Protection and Privacy".Of all the complaints closed in 2023, eight (8) were considered "well-founded", of which four (4) related to "Personal Data Protection and Privacy", two (2) to "Employee Welfare", one (1) to "Diversity and Inclusion" and one (1) to "Harassment". For all the cases analysed by EDP's Ethics Committee, a set of 33 (thirty-three) action measures were proposed, relating to Training, Revision or Improvement of Procedures, Disciplinary actions, among others. The entire complaint management process follows, at each stage, essential guiding principles such as independence, impartiality and objectivity in the analysis and treatment of registered cases, along with the guarantee of absolute confidentiality. Complaints can also be reported anonymously, being guaranteed, notwithstanding this condition, the possibility of interaction with the whistle-blower, as deemed necessary. EDP ensures the protection and non-discrimination of whistle-blowers who make their communications or complaints, in good faith and in a well-founded manner, even if the facts reported are not precise or do not give rise to any disciplinary or judicial proceedings. Any acts of reprimand or retaliation, directly or indirectly motivated by a complaint, causing any damage to the complainants, are not accepted. EDP provides access to the Speak Up channels, through its website, as well as to the respective Whistleblowing Management Regulation, that can be read at: Whistleblowing Management Regulation Speak Up | edp.com More detailed information on EDP's whistleblowing management process can be found in the "Ethics and Compliance" chapter of the Sustainability section of the Management Report and its annexes, as well as in the Annual Report of the Ethics Ombudsman, available on the Company's website. III. Internal Control and Risk Management 50\. People, bodies, or committees responsible for internal audits or implementation of internal control systems The EDP Group's Compliance Management System, aligned with the risk management model, is founded on an internal control system based on the “three lines of defence”, in order to properly identify and manage the risks arising from the activity, under the terms of which: • The First line of defence (Business): has, among others, the responsibility for the daily and proactive management of compliance risks, in line with the established regulations. The top management of each functional, business or support unit and all its employees are part of it. • The Second line of defence (Compliance): it has, among others, the responsibility of ensuring business support in the identification, analysis, evaluation, mitigation, and monitoring of risk, as well as challenging and questioning the potential risks that may arise. The main responsibles are the Compliance & Internal Control Global Unit, 

431 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance supported by the Compliance Departments of EDP España, EDP Energias do Brasil and EDP Renováveis, and a network of Compliance Partners, Compliance Business Partners and the Local SCIRF (Internal Control over Financial Reporting System) Managers. • The Third line of defence (Internal Audit): it has, among others, the responsibility for carrying out independent audits to the Compliance Management System. These audits may also be carried out by independent external entities with recognized capacity for that purpose. As defined, this model allows the rationalization of resources and efforts, promotes coordination between functions and the homogenization of language connecting all Business Units/Departments through a common infrastructure, sharing the same information systems and processes, and promoting the effective implementation of compliance mechanisms at the different levels of the organization. The compliance function's mission is therefore to promote a culture of compliance and integrity, by identifying relevant compliance risks and by disseminating and coordinating the implementation of mechanisms that promote compliance, providing proactive and systematic advice to the entire organization. The Compliance & Internal Control’s activity is essentially based on four pillars, namely: • identification analysis and assessment of compliance risks; • promotion and coordination of the implementation of policies, procedures, and other control mechanisms, in order to mitigate the identified compliance risks; • monitoring of procedures and other compliance mechanisms adopted, in order to assess the maintenance of their adequacy and effectiveness; • periodic reporting to the Executive Board of Directors and the Financial Matters Committee/Audit Committee of the most relevant topics that may represent a significant risk for the Group. The Compliance & Internal Control also has as main responsibilities to contribute to the continuous improvement of risk management processes associated, in an external plan, with legal and regulatory compliance and, in an internal plan, with compliance with the internal regulations and procedures in force, also ensuring the implementation of the Internal Control over for Financial Reporting System (SCIRF). In the performance of its duties, the Compliance & Internal Control reports hierarchically to the Chairman of the Executive Board of Directors and functionally to the General and Supervisory Board, through its Financial Matters Committee/Audit Committee. For its part, the Executive Board of Directors establishes a culture of tone at the top in Compliance matters, approving, disseminating, and ensuring the implementation of EDP's Compliance Management System in line with the Group's strategic objectives. The General and Supervisory Board, through the Financial Matters Committee/Audit Committee, monitors and supervises the implementation of the referred compliance culture and approves the business plan of the Compliance & Internal Control’s activity plan, also ensuring the follow-up of the respective execution. The Group's Compliance Management System, approved by the Executive Board of Directors and by the Financial Matters Committee/Audit Committee, is formalized through EDP’s Compliance Standard, updated in 2022, and is aligned with best international practices, as detailed in the Management Report, Performance, Sustainability, Future- Proof Organisation, Ethics and Compliance, with EDP having obtained the respective certification namely with the references of ISO 37301:2021 Compliance Management Systems – Requirements with guidance for use. This system demonstrates the EDP group’s commitment to ensure (i) an adequate identification, assessment, and management of compliance risks, in order to minimize the risk of sanctions, namely financial and possible operational and reputational impacts, and (ii) the confidence of its stakeholders, reinforcing the competitiveness of the EDP Group. The Compliance Management System allows for the harmonization of guidelines and methodologies for compliance management, across the organization and different regulatory scopes, ensuring alignment with other internal policies and procedures, seeking the continuous improvement of the activities developed. Based on the defined governance model, the EDP Group's Compliance Management Sys- tem develops from a risk assessment, which is reviewed periodically or whenever there are material changes in the legal and regulatory context or in the organizational context, and that allows the identification of the legal requirements and others compliance obligations or of the most relevant normative scopes for the organization, resulting in the structuring and development of different Specific Compliance Programs, through a process that goes through different sequential phases: (i) planning, (ii) conceptual structuring and design, (iii) support for implementation; (iv) monitoring of implementation and (v) ongoing mainte- nance and continuous improvement. 

432 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance At the Specific Compliance Program level, following the methodological approach of the Group’s Compliance Management System and as a function of specific risks identification and assessment, policies, procedures, and other compliance mechanisms are developed, through which the fundamental principles in compliance management are formalized and detailed control rules and mechanisms implemented, reflecting on the activities developed internally or by third parties on behalf of EDP, and which are key elements for the dissemination of a culture of compliance across the Group. Another fundamental element for the development of Specific Compliance Programs is the training and awareness actions carried out both at the transversal group level and at a specific to certain Business Units or regulatory scope level. The compliance function ensures the follow-up and monitoring of the development, operation, and implementation of Specific Compliance Programs, it reports on its activities to the Executive Board of Directors and the General and Supervisory Board, though its Financial Matters Committee/Audit Committee. For its part, and in accordance with the respective annual activity plan, the Internal Audit function conducts specific audit work, addressing compliance topics. In addition, the Compliance Management System and some Specific compliance programs are also subject to independent external review. The results of the monitoring and any recommendations issued by internal and / or external auditing are considered for the purpose of improving compliance management, in a perspective of continuous improvement. For more information on the development of the main CSPs, see the "Ethics and Compliance" section of the sustainability section of the Management Report (Performance, Sustainability, Future-Proof Organisation). From the established governance model, and with the objective of identifying, assessing, monitoring, and controlling the risks to which the EDP Group is exposed, in addition to the Compliance & Internal Control, the Risk and the Internal Audit – Corporate Global Units also play an important role. The Risk – Corporate Global Unit is primarily responsible for coordinating risk assessment studies for the Group, with the aim of supporting the Executive Board of Directors in their control and mitigation and providing integrated risk-return analyses, as presented the respective chapter, which activity is detailed in items 52 to 54 of this Annual Report. In turn, internal audit, formalised in the EDP Group's Basic Internal Audit Standard, revised in 2021, is an objective and independent activity, of guarantee and advisory, aimed at adding value and improving operations of EDP Group, assisting the organization in pursuing its objectives, through a systematic and disciplined approach in assessing and improving the effectiveness of risk management, control, and governance procedures. The internal audit function has the mission of increasing and protecting the value of EDP, providing assurance, advisory and insight, covering several fields of action. The EDP Group's internal audit is a corporate function performed by the Internal Audit Global Unit, which has a double dependency, on the one hand administrative structure of the Executive Board of Directors and, on the other, functional of the General and Supervisory Board, to which reports the respective exercise. The EDP Group's Internal Audit are present in Portugal, Spain, the United States of America, Brazil and Singapore, depending functionally on Internal Audit. In addition to conducting operational and regulatory audits to Business Units in Portugal and auditing information systems at the Iberian level, Internal Audit Global Unit main duties are to propose audit policies and objectives, in accordance with the law and with the best international practices, ensuring the harmonization of internal audit methods, processes and manuals and with a view to implementing the respective support tools, establishing and managing the systematic planning of internal audits at the Group level. Regarding the areas that make up the Internal Audit Global Unit, although each area has (operational and regulatory audits and information systems audits) its specific duties, multidisciplinary and the growing interaction between the operational audit and information systems audit teams (with an Iberian scope) have allowed synergies in the analysis of information and data extracted from computer systems to support business processes and, therefore, a better quality of the conclusions obtained, a closer proximity to the business and an increasing monitoring of the degree of evolution of the projects most relevant. On the other hand, Internal Audit Global Unit commitment to quality and the continuous improvement of the processes and activities it carries out led to the creation of the Quality and Continuous Improvement Office at Internal Audit, which, in a fundamentally methodological aspect, ensures an internal service with a view to increasing value added in relation to the internal audit activity in the EDP Group. The Internal Audit Departments, as well as all professionals assigned to this function, govern their performance by the Fundamental Principles for the Practice of Internal 

433 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance Auditing, the Code of Ethics and the International Standards for the Professional Practice of Internal Auditing approved by The Institute of Internal Auditors (IIA). EDP Group has internal auditors experienced in several areas (e.g., finance, accounting, legal, information systems), with a deep knowledge of the Group, allowing a multipurpose and transversal analysis of the issues in question and of the activities carried out. In addition to specific training and experience in the area, the employees assigned to the information systems audit area know the systems implemented in the Group and follow market trends, allowing them to obtain a broad view of the systems and processes with the greatest technological risk. and of greater relevance for the different Business Units. The internal audit activities are developed based on plans aligned with the objectives and mission of the function, in which the audit works that comprise them have as main inputs the consultation with the government bodies and the alignment with the Group's Strategic Plan and with the sustainability objectives, the prioritization of processes based on the risk analysis carried out by Internal Audit, the interactions with the statutory auditor throughout the year and the consideration of topics of interest that it has identified in the scope of the SCIRF audit and the financial audit, international trends and best practices in matters of internal audit, and the identification and assessment of the control environment existing in the various lines of defence that affect each process, in a perspective of Combined Assurance. Internal Audit Global Unit lines of activity are the analysis of the effectiveness and efficiency of operations, reliability, and integrity of information, both financial and operational, compliance with internal procedures and standards, compliance with external standards, auditing of information systems and integrity of assets. The changing macroeconomic, social, and political context, as well as the growing technological transformations and the news and changes that have been affecting the energy sector in general and the EDP Group in particular have forced a constant adaptation of the internal audit activity in order to maintain an ability to respond adequately to the challenges ahead, aiming to maximize the added value that this activity can and should offer to its stakeholders. Internal Audit Global Unit has been monitoring the extent and development of the Group's activity in new markets, business lines and geographies, incorporating in its business plan, actions aimed at evaluating and reinforcing the existing internal control environment. The continuous auditing model has evolved consistently, consolidating the methodology, continuing existing audits, implementing new audits to evaluate different business areas, some with real-time analysis, with a set of new indicators and automation of communication exceptions to the audited entity at the time they are detected. It is a robust monitoring and evaluation model, very relevant for the automatic processing of a high volume of data, allowing to obtain efficiency gains in terms of internal control and in the prevention and detection of irregularities. Within the scope of information systems audits, actions have been carried out covering several areas of high criticality, considering, in particular, the digitization program underway at the EDP Group, which has been a lever for strengthening and growing business processes, the increase in processes/activities analysed by continuous auditing and the expansion of routine automation in order to speed up the monitoring of the Group's information systems. In recent years, the existing competencies in the field of information systems and data analytics have been strengthened by recruiting employees who are specialists in these matters in an internal audit perspective, complementing the profiles already existing in the information systems and operational audit teams. The relationship with the various stakeholders is developed, mainly, through periodic meetings with the Financial Matters Committee/Audit Committee and the members of the Executive Board of Directors, interactions with the Business Units, both at the level of the Boards of Directors and with those in charge of the audited areas, interactions with other areas of the Group, such as risk, sustainability, legal advice, human resources, regulation, strategy, management control, compliance, information systems, in order to identify risk areas and to ensure the update on the various matters of the organization. Internal Audit Global Unit carries out, annually, a process of self-assessment of the Group's internal audit activity, which consists of a reflection and analysis on the structure, composition, skills, relationship, reports, methodologies, DAI procedures and work carried out throughout the year, among others, and includes a global conclusion expressed by the responsible person of Internal Audit's activity in line with the best practices of the function. On the other hand, Internal Audit Global Unit activity and performance is evaluated annually by the Financial Matters Committee/Audit Committee based, among others, on the analysis of the interaction that the Commission develops throughout the year with DAI and on the analysis of information and documentation made available by it regarding the process of its self-assessment. Internal Audit Global Unit activity has been subject to external evaluations since 2010 by the IIA (every 5 years, as established in the International Standards for the Professional 

434 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance Practice of Internal Auditing) and, since that date, the opinion of the evaluation teams has been that the internal audit activity "Generally Complies" with the International Standards for the Professional Practice of Internal Auditing and the IIA Code of Ethics, this qualification being the highest granted by the IIA. The last external evaluation took place in 2020, in all locations where the internal audit function is developed, with the aim of obtaining joint independent certification, with the opinion issued in the external evaluation reports being that the internal audit activity “generally complies” with the Standards and Code of Ethics issued by the IIA in all locations (Portugal, Spain, United States and Brazil), in all its aspects (government, personnel, management and procedures). It is also worth mentioning, and in line with the information described above, the competence of the General and Supervisory Board, which, under legal terms, permanently monitors and evaluates the internal procedures related to accounting and auditing matters, as well as the effectiveness of the risk, the internal control and the compliance management system. This competence is attributed to the Financial Matters Committee / Audit Committee, which is responsible, among other tasks, for permanently monitoring and supervising: (i) financial matters and accounting practices; (ii) internal audit practices and procedures; (iii) the internal mechanisms and procedures of the Internal Control over Financial Reporting System (SCIRF); (iv) matters relating to the risk management and control system; (v) the activities and mechanisms of the compliance management system and (vi) the activity and independence of the company’s Statutory Auditor. 51\. Description of hierarchical and/or functional dependency on other company bodies or committees In the performance of their duties, the Internal Audit Global Unit administratively reports to the Executive Board of Directors and functionally reports to the General and Supervisory Board that supervises its activity through the Financial Matters Committee/Audit Committee. On the other hand, the Compliance & Internal Control Global Unit reports hierarchically to the Executive Board of Directors, and functionally to the General and Supervisory Board through the Financial Matters Committee/Audit Committee. The Risk Global Unit reports hierarchically to the Executive Board of Directors, without prejudice to the permanent monitoring, by the Financial Matters Committee/Audit Committee, of risk-related matters, as described in item 52 below. 52\. Other company areas with risk control duties The risk management is an integral part of the common practices of business management, and it is the responsibility of all, from the Executive Board of Directors right down to the individual staff member. Each one is responsible for knowing the risks existing in their area of intervention and for managing them in accordance with their role, expertise, and delegated responsibilities. The EDP Group manages its meaningful risks in a portfolio approach, optimizing the risk/ return trade-off transversely across its business areas, aiming to create value and to stand out in the markets where it operates. The EDP Group also works towards a permanent progress of its risk management processes in order to reflect the evolution of its needs and to maintain its alignment with international risk management best practices. The integration of risk management in the most relevant business and decision-making processes is promoted as part of i) strategic development, ii) investment decisions, iii) business plan and iv) operations management, with the purpose of ensuring stability in results and optimize its response to changes in context and opportunities. The risk management process is structured around 3 lines of defence (business operation, risk management/ compliance and internal and external auditing), each led independently and ensuring an adequate level of segregation relative to one another. The functions of risk identification, analysis, evaluation, treatment, and monitoring are followed by a set of bodies with clearly established roles and responsibilities, typified by Group policies that are approved and ratified by the competent bodies of the Group. Below are brief descriptions of these bodies, complemented by the responsibilities available on the EDP website: EDP Risk Governance Model | edp.com: • The General and Supervisory Board, in particular the Financial Matters Committee/ Audit Committee, is responsible for permanently monitoring the effectiveness of the risk management system, namely in terms of risk identification, assessment, control and management and assessing the degree of internal compliance with the Company's risk management system, continuously monitoring its performance and effectiveness, in articulation with the Executive Board of Directors, namely the risk control policies, the identification of key risk indicators (KRI) and the integrated risk evaluation methodologies, and must evaluate and issue its opinion on the EDP Group's strategic guidelines and corporate risk management policy, prior to their final approval by the Executive Board of Directors. The Financial Matters Committee/Audit Committee defines in its annual planning sessions dedicated to risk management issues, in order to 

435 Part III Integrated Annual Report 2023 Corporate Governance Report | Information on Ownership Structure, Organisation and Corporate Governance monitor the evolution of the Group's main exposures and key risk indicators, as well as addressing issues related to financial, strategic, ESG, business and operational risks. • The Executive Board of Directors is ultimately responsible for the decision, supervision and control of risk management, and is responsible for setting the EDP Group's management objectives and policies. In addition to sharing the responsibilities defined for the Boards of Directors, it is also responsible for defining the Risk Appetite set out in the Business Plan, defining the EDP Group's risk policies (in particular, the respective exposure limits by risk category) and for allocating resources in accordance with the risk-return profile of the various options available. • Risk Global Unit headed by the Chief Risk Officer, performs a function that is independent from the conduct of business, and supports the Executive Board of Directors at the level of the second line of defense. Its mission is to promote an integrated vision of the EDP Group's risk, ensuring the alignment of risk policies and limits with the appetite defined for the Group, and coordinating risk-return studies at Group level, in order to support the EBD in monitoring and mitigating the main risks. • The risk-owners of the Business Units and Corporate Global Units act as the first line of defence in the risk governance model, being all the business managers who assume risk in their day-to-day activities and act in accordance with the defined risk strategies. • Local structures for risk management (risk-officers) assume a key role on operationalizing risk management, typically under the direct hierarchical dependence of the respective Board of Directors, with functional coordination with the Group's Chief Risk-Officer, acting in a segregated manner and independent from business operation. In large and/ or particularly complex Business Units local replicas of risk management corporate structure exist, articulated with the Risk. Furthermore, there are several regular forums for the discussion, analysis, and issue of opinions on risk-related topics: • The main objective of the EDP Group’s Risk Committee is to support the decisions of the Executive Board of Directors in the identification, analysis, evaluation, treatment and monitoring of risk. This Committee, which reports to the Executive Board of Directors, meets periodically and, whenever necessary, extraordinarily, preferably at least quarterly. The Committee is composed of the Group's main decision-makers and risk managers (members of the Executive Board of Directors, key corporate areas and members with responsibility for risk management of the main platforms/geographies who are members of the Audit Committee). • The Individual Risk Committees are created and conducted at the Group's Business Unit level when the degree of complexity of risk management justifies it, assuming a structure replicated from the Group's Risk Committee. These committees are typically coordinated by the respective risk-officer and include members of the Board of Directors, key areas of the Business Unit, as well as a member of the Risk - Corporate Global Unit, to ensure alignment at the Group level. 53\. The main types of risks to which the company is exposed in its business The EDP Group's risk taxonomy aggregates, from an integrated perspective and in a common language, the various risk mappings existing at the level of the Group's various Business Units, and is structured around four major families: strategic & ESG, business, financial and operational. The figure below shows the risk categories to which EDP is exposed. For additional information and details on the various risks to which EDP is subject, which fall into the above categories, please consult EDP's website: EDP's Risk Taxonomy | edp.com

Company mechanisms for monitoring transactions with related parties As part of the qualitative reinforcement of governance practices, and since 2009, EDP and, in particular, the General and Supervisory Board, has been promoting the revision of the internal regulations governing transactions with related parties, given the constant search to adopt the best practices by the Company. To this end, internal regulations that regulate conflicts of interest and business between related parties were reviewed, and, in 2023, the Policy on Transactions with Related Parties was revised, available for consultation on the EDP website: Transactions with Related Parties Policy | edp.com. The Financial Matters Committee/Audit Committee is responsible for issuing a reasoned opinion on matters subject to a prior opinion by the General and Supervisory Board, which concern transactions between related parties, supported, whenever applicable, by reasoned opinions from the Risk and Compliance Departments, which must be made known to the General and Supervisory Board. 90\. Transactions that underwent controls in the year Attentive to the current reporting obligations, the Executive Board of Directors, during 2023,sent information on transactions with related parties to the General and Supervisory Board and/or the Financial Matters Committee/Audit Committee. The following transactions are included in this report: • EDP Group, through EDP Clientes, S.A. provided electricity and gas supply services as well as the installation of solar panels to the company Cementos Tutela Veguín in the amount of approximately 50.1 million Euros (Cementos Tutela Veguín is a subsidiary of the Group Masaveu, which, in turn, holds 55.9% of the company Oppidum Capital, SL); • Additionally, the EDP Group, through the company EDP Comercial - Comercialização de Energia, S.A., agreed with the company Exus Management Partners to supply equipment and carry out work relating to the interconnection of two photovoltaic plants to the Public Service Electricity Grid, worth approximately 1.7 million euros (Exus Management Partners is a subsidiary of the Masaveu Group, which in turn owns 55.9% of the company Oppidum Capital, S.L); • As disclosed to the market on 27 October 2023, EDP España, S.A.U. entered into a partnership with Corporación Masaveu, S.A. through the sale of a 50% stake in the Aboño power plant, reflecting an enterprise value of around 350 million euros and an equity value of 60 million euros for 100% of the asset (Corporación Masaveu is a sub- sidiary of the Masaveu Group, which in turn owns 55.9% of the company Oppidum Capital, S.L); • As disclosed to the market on 29 December 2023, EDP, through its subsidiary EDP Renováveis, S.A., agreed with ACE Investment Fund I LP and ACE Investment Fund II LP, majority-owned by China Three Gorges, to purchase the respective minority stakes of 49% in wind portfolios in Portugal, Poland and Italy, for a total amount of 0.57 billion euros. • As disclosed to the market on 29 December 2023, EDP signed a sale and purchase agreement for a 50% stake in Energia Asia Consultoria, Lda. with China Three Gorges for a total expected consideration of around 100 million euros, subject to ad- justments until the transaction is finalised. The General and Supervisory Board noted that, with basis on the cases analysed and information provided by the Executive Board of Directors for 2023, there was no evidence that the potential conflict of interests in EDP operations were resolved contrarily to the Company’s interests. At the same time, it is important to highlight Article 17(2) of EDP Articles of Association, that defines a number of matters subject to prior opinion from the General and Supervisory Board. This corporate body has competences to set the parameters for measuring the economic or strategic value of the operations that must be submitted for its opinion, and these were updated by the referred Board on the 13 May 2021. In this context, in 2023 eleven investment/divestment operations were submitted for the prior opinion of the General and Supervisory Board, with an average value of more than 350 million euros, as well as six financing operations, with an average value of approximately 1.4 billion euros, with three of these investment/divestment operations underlying a transaction with a related party. Regarding the use of the expedited mechanism for issuing a prior opinion, two operations were submitted to the General and Supervisory Board for financing reasons, with an average value of approximately 930 million euros, and five operations regarding investments or divestments, with an approximate average amount of 430 million Euros. The issue of senior green debt securities totalling 1,350 million Euros was the largest value transaction, approved under this mechanism during 2023. 

444 Part III Integrated Annual Report 2023 Corporate Governance Report Also in this context, during the 2023 financial year, eight operations were submitted to the United States of America Business Affairs Monitoring Committee for a prior opinion, with an average value of 250 million dollars, with the maximum value of which was 435 million dollars. Regarding the issuance of a prior opinion by an expedited mechanism, one operation was submitted to the United States of America Business Affairs Monitoring Committee, with a of 400 million dollars. Regarding transactions analysed by the United States of America Business Affairs Monitoring Committee, none of them had a related party transaction underlying them. 91\. Procedures and criteria applicable to the supervisory body's prior assessment of transactions between the company and holders of qualifying shareholdings or entities related to them in any way The rules in force applicable to the issuance of a prior opinion and to the expedited mechanisms of opinion in urgent cases of the General and Supervisory Board were updated on 13 May 2021, as well as the procedures for communication and provision of clarifications between that corporate body and the Executive Board of Directors. The Articles of Association of EDP also establish that the General and Supervisory Board should set the parameters for measuring the economic or strategic value of the operations that must be submitted to it for an opinion, as well as establish expedited mechanisms for issuing an opinion in urgent cases or when the nature of the matter justifies it and the situations in which exemption from issuing such an opinion is permitted (Article 21 (7)). In fact, the expedited mechanism for issuing an opinion by the General and Supervisory Board can only occur in situations of exceptional urgency or when the nature of the matter justifies it, as set out in the EDP’s Articles of Association and the Internal Regulations of the General and Supervision (Article 15(5)). With reference to prior opinion mechanism, General and Supervisory Board of EDP established a set of demanding rules regarding the conclusion of business between related parties, aimed at preventing situations of conflict of interests. In this context, it is important to highlight the provisions of the Transaction with Related Parties Policy – reviewed in May 2023 - regarding the procedures and criteria applicable to the intervention of the supervisory body for prior assessment of the business purposes to be carried out between the Company and holders of qualifying holdings or entities that are in any relationship with them. In particular, in legal transactions or de facto situations between related parties that are likely to give rise to a conflict of interest between the parties involved, relevant to the pursuit of EDP's interest, together with the request for a prior opinion from the General and Supervisory Board or its waiver, the Executive Board of Directors must provide the following information: • Summary description of the operations and the responsibilities taken up by the parties; • Outline of the procedures used to select the counterparty, i.e., whether the operation was based on a call for tenders/market consultation procedure or direct contract award; • In the event of direct contract award, the reasons for this decision; • In cases of calls for tenders/market consultation procedures, the type of contact established with the potential interested parties and the identity of those parties; • In case of competitive tenders, the details of the different tenders and the criteria used for selection; • The parameter used to check whether the transaction was performed under “normal market conditions for similar operations”; • Measures adopted to prevent, mitigate risks, or solve potential conflicts of interests, namely the issuing of fairness opinions by independent entities prior to taking a decision regarding the performance of a Transaction with a Related Party; • Indication, if applicable, of the multi-annual nature of the operation, in which case the initial date of the award/contract must be reported, as well as the date on which the supplies and/or services are provided. With respect to legal business or cases that exist between related parties that are likely to give rise to a conflict of interests between those involved, which could impact the interests of EDP, these should be subject to a preliminary opinion from the General and Supervisory Board: • if the Financial Matters Committee/Audit Committee can meet before the General and Supervisory Board meeting, an opinion from this Committee should be requested, which should be presented to the General and Supervisory Board for decision- making purposes; • if it is not possible for the Financial Matters Committee/Audit Committee to meet, the assessment of the potential conflict of interests must be made directly by the General and Supervisory Board within its decision-making authority.

That policy also establishes that proposals for the election of members of the General and Supervisory Board and the Executive Board of Directors must be submitted to the General Shareholders’ Meeting, duly substantiated with regard to the candidate's profile and the role they will fulfil, so that shareholders can verify the suitability of the candidates' profile, knowledge, and CV, considering the duties to be performed. The criteria include (i) promoting equal rights and opportunities in the face of diversity, (ii) valuing diversity, particularly in terms of age, gender, geographical origin, qualifications, skills, and experience, (iii) promoting an increase in the number of members of the under-represented gender and (iv) avoiding potential conflicts of interest. This selection policy also sets out the competences that the members of the Executive Board of Directors and the General and Supervisory Board must possess, among which the following stand out: (i) technical and professional skills appropriate to the position, (ii) integrity, ethics and professional and personal values, (iii) sufficient knowledge of the legal, regulatory and statutory rules applicable to their duties and to the Company, (iv) sufficient availability to fulfil their legal and statutory duties, (v) fulfilment of the independence requirements demanded by law and the articles of association, (vi) commitment to the provisions of the Company's codes, policies and Internal Regulations, (vii) commitment to complying with best corporate governance practices, (viii) skills and experience in company management, risk management and supervision appropriate to the position and (ix) knowledge of the industry and experience in the sector. In particular, with regard to gender diversity, it is necessarily accommodated by virtue of compliance with Law 62/2017, of 1 August, on the balanced representation of women and men in the management and supervisory bodies of entities in the public business sector and companies listed on the stock exchange. EDP also has a diversity policy which establishes (i) the commitment to promote mutual respect and equal opportunities in the face of diversity, (ii) the recognition of differences as a source of strengthening human potential Item 11 | Items 15 to 17 | Items 30 to 33 | Annex I 

448 Part III Integrated Annual Report 2023 Corporate Governance Report REOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION and valuing diversity in the organisation, management and strategy, and (iii) the adoption of positive discrimination and awareness-raising measures internally, but also in the community, with a view to the effective implementation and effectiveness of the diversity policy. At the EDP Extraordinary Annual General Shareholders’ Meeting held on 19 January 2021, the members of the Executive Board of Directors were elected for the three-year period 2021-2023, and at the EDP Annual General Shareholders’ Meeting held on 12 April 2023, a member of the Executive Board of Directors was elected for the remainder of the current three-year period 2021-2023, with the current representation of this body being 40%, ensuring greater compliance with the provisions of the applicable legislation. At the Annual General Shareholders’ Meeting held on 14 April 2021, the members of the General and Supervisory Board were elected, and the current representation of this body is also higher than that provided for in the applicable legislation. According to EDP's current Gender Equality Plan, updated for the 2023-2024 period, available on EDP's website and at www.cmvm.pt, gender equality is of civilisational importance, as a corollary of equal rights, freedoms, guarantees, opportunities and recognition between men and women, also allowing skills and knowledge to be enhanced by including everyone, promoting a better working environment and motivation and, consequently, higher levels of productivity and talent retention. II.2.2. The management [II.2.2. (1)] and supervisory bodies [II.2.2. (2)] and their internal committees [II.2.2. (3)] are governed by regulations – notably regarding the exercise of their powers, chairmanship, the frequency of meetings, operation, and the duties framework of their members – fully disclosed on the website of the company, whereby minutes [II.2.2.(4)]/[II.2.2.(5)]/[II.2.2.(6)] of the respective meetings shall be drawn up. ADOPTED The General and Supervisory Board, the Executive Board of Directors, the Financial Matters Committee/Audit Committee (FMC/AUDC), the Corporate Governance and Sustainability Committee (CGSS), the Remunerations Committee (RCMC) and the United States of America Business Affairs Monitoring Committee (CAN) have specific Internal Regulations that establish its functioning (in particular the exercise of the respective duties, chairmanship, periodicity of meetings, functioning, duties of their members and duty to draft detailed minutes of the respective meetings).

ADOPTED [II.2.3.(1)] Governing Bodies [II.2.3.(2)] The information on this sub-recommendation can be found separately in EDP’s Integrated Annual Report and in the Annual Report of the General and Supervisory Board, both published on EDP’s website. Item 59 | Annex V II.2.4. The companies adopt a whistle-blowing policy that specifies the main rules and procedures to be followed for each communication [II.2.4.(1)] and an internal reporting channel that also includes access for non-employees, as set forth in the applicable law [II.2.4.(2)]. ADOPTED Since 2006, EDP has had a policy for reporting irregularities [II.2.4.(1)]. In 2022, and following the entry into force of Law no. 93/2021, of 20 December, which transposes Directive (EU) 2019/1937, EDP reformulated its whistleblowing channels [II.2.4.(2)], with a view to structuring an Integrated Whistleblowing Management System. To this end, EDP adopted a technological platform common to all whistleblowing channels, which safeguards the segregation of information for each channel. Also in 2022, EDP approved the Speak Up Whistleblower Management Regulation, which establishes the mechanisms and procedures for receiving, retaining, and processing reports received by the Company on allegedly unethical behaviour that does not comply with the law and internal regulations in force. Under the terms of these regulations, reports, which can be made by interested parties from any EDP Group company (including non-employees), are treated as confidential information by all those who receive information about the facts reported, and the anonymity of the whistleblower is ensured if they so request. For more information, see: Speak Up Channels and Whistleblowing Management Regulation Speak Up. In recent years, the Integrity Policy, as well as the other compliance procedures and mechanisms associated with the Specific Integrity Compliance Programme, have been the subject of internal training for employees, and have also been published internally for consultation on EDP's internal communication channels. As part of the structuring of the Specific Compliance Programme to Combat Money Laundering and Terrorist Financing, specific internal regulations, and a transversal procedure for reporting suspicious transactions were also implemented by the obliged entities. In 2022, this whistleblowing channel, which has been in place since 2006, was restructured for reporting potential irregularities in financial matters, and a specific communication channel was also made available for potential irregularities related to anti-money laundering and anti-terrorist financing violations, currently included in the Speak Up Channels mentioned above. In 2023, internal training and awareness- raising activities were also carried out regarding the Speak Up Channels and the procedures implemented for managing and handling complaints. For more information: Channel for reporting irregularities related to Money Laundering or Terrorist Financing. Item 15 | Item 49 | Item 50 to 55 II.2.5. The companies have specialised committees for matters of corporate governance [II.2.5.(1)], remuneration [II.2.5.(2)], appointments of members of the corporate bodies [II.2.5.(3)] and performance assessment [II.2.5.(4)], separately or cumulatively. If the Remuneration Committee provided for in Article 399 of the Portuguese Commercial Companies Code has been set up, the present Recommendation can be complied with by assigning to said committee, if not prohibited by law, powers in the above matters. ADOPTED [II.2.5 (4)] The Remuneration Committee elected by the General Meeting (CVEN GSM) is responsible for submitting a proposal for the remuneration policy of the members of the General and Supervisory Board, the members of the Board of the General Meeting, the Statutory Auditor and the members of the Environment and Sustainability Board. One of the guiding principles of CVEN GSM 's activity is the definition of a simple, clear, transparent policy in line with EDP's culture, so that remuneration practices can be based on uniform, consistent, fair, and balanced criteria. Within this framework, the remuneration policy proposed by CVEN GSM aims to ensure levels of homogeneity and stability that are compatible not only with the necessary cohesion of the governing bodies and organisations, but also and above all with their non-executive nature, and it is not considered desirable to award variable remuneration that is necessarily conditional on the performance of the respective members. In this context, it is considered appropriate to defend the - growing - differentiation between the remuneration treatment of directors with executive duties, on the one hand, and that of other members of other corporate bodies, namely supervisory and supervisory bodies, on the other. As such, and in line with the provisions of the applicable legislation, the fixed remuneration safeguards the distance between the exercise of supervisory and/or oversight duties and the risk inherent in the business activity, as well as the fundamental independence within the scope of impartial and effective supervision and/or oversight. This differentiating treatment is even reflected in the IPCG Code itself, specifically under the terms of the Principle of Chapter VI. In this instance, the assessment of the performance of members of governing bodies other than the members of the Executive Board of Directors, the General and Supervisory Board and the Specialised Committees is carried out in a different way, and solid mechanisms of checks and balances and internal control are sufficient for this purpose. In this sense, as there are, in addition to the shareholder prerogative at the Annual General Shareholders’ Meeting, internal mechanisms of an instrumental nature to assess, at first hand and with in- depth knowledge, the performance of the members of the governing bodies, there are no benefits to establishing an additional mechanism to assess the individual performance of each of the members of EDP's governing bodies. In this regard, the performance assessment mechanisms are duly safeguarded, namely through the assessment and self-assessment process of the General and Supervisory Board, certified by a specialised external entity, including the Chairman of the Board of the General Meeting of Shareholders, and the assessment process of the Statutory Auditor by the FMC/CAUD. Considering that the Remuneration Policy proposed by CVEN GSM only proposes to provide for the remuneration - always of a fixed nature - of the aforementioned bodies and corporate bodies and that the Company has established effective and resilient internal evaluation and control mechanisms to assess the individual performance of each member, including their contribution to the way in which the body operates and the relationship between the various bodies of the Company, this sub-recommendation [II.2.5(4)] should be considered as explain equivalent to adoption. [II.2.5.(2)] The company also has a Remuneration Committee of the General and Supervisory Board, which is responsible for preparing and proposing the policy and corporate objectives for setting the remuneration of the Chairman of the Executive Board of Directors and the Directors, Item 21 | Item 29 | Remunerations Report | Annual Report of the General and Supervi- sory Board 

450 Part III Integrated Annual Report 2023 Corporate Governance Report REOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION as well as setting the respective remuneration, monitoring and evaluating their performance for the purposes of determining variable remuneration and also monitoring the disclosure of external information on the remuneration and remuneration policy of the Executive Board of Directors, namely the Remuneration Report, as established in the respective Internal Regulations. [II.2.5. (1)] With regard to corporate governance, the General and Supervisory Board also has a Corporate Governance and Sustainability Committee, which is responsible for analysing this issue. [II.2.5 (3)] As provided for in Article 14(1)(h) of the respective Internal Regulations, the General and Supervisory Board is responsible for "monitoring the definition of criteria and competences required in the structures and internal bodies of the Company or the Group or convenient to observe and their repercussions on the respective composition, as well as drawing up succession plans." In addition, pursuant to article 28 (c) (vi) of the Internal Regulations of the General and Supervisory Board and article 12 (1) (r) of the Internal Regulations of the Corporate Governance and Sustainability Committee, the Corporate Governance and Sustainability Committee is the specialised committee responsible for monitoring matters relating to succession plans. The Corporate Governance and Sustainability Committee is the specialised committee entrusted with monitoring matters relating to succession plans, namely monitoring the preparation, in coordination with the Executive Board of Directors, of succession plans for the structures and internal bodies of the Company, Subsidiaries and other entities in relation to which the Company has the right to appoint the members of the governing bodies. This analysis should cover all the key positions that are most instrumental in the fulfilment of the Strategic Plan, which should be previously identified by the Executive Board of Directors and submitted to this Committee. Relations between Corporate Bodies II.3.1. The Articles of Association or equivalent means adopted by the company set out the mechanisms to ensure that, within the limits of the applicable laws, the members of the management and supervisory bodies have permanent access to all necessary information to assess the performance, situation and development prospects of the company, including, specifically, the minutes of the meetings, the documentation supporting the decisions taken, the convening notices and the archive of the meetings of the executive management body, without prejudice to access to any other documents or persons who may be requested to provide clarification. ADOPTED EDP's Articles of Association expressly state that the different bodies of the Company must, to the extent of their respective competences, create the necessary conditions for harmonious, articulated, and informed action in the performance of their duties, and mechanisms for reporting and sharing information have been implemented, as mentioned in relation to recommendation II.1.1. In addition, the Internal Regulations of the Executive Board of Directors, the General and Supervisory Board and the various Committees contain provisions establishing the need to report, namely to the supervisory body, information on the annual plan of activities of meetings, resolutions, and minutes. The recommendation is also included in Article 5 of the Internal Regulations of the Executive Board of Directors. Currently, EDP also has an internal instrument that allows it to systematise the principles of action and the rules to be observed in the interaction of the Executive Board of Directors with the General and Supervisory Board, in development of the legal framework, the Articles of Association and the Regulations that deal with these matters. Items 21 to 45 II.3.2. Each body and committee of the company ensures, in a timely and adequate manner, the interorganic flow of information required for the exercise of the legal and statutory powers of each of the other bodies and committees. ADOPTED All the Internal Regulations establish reporting and information-sharing mechanisms. In particular, the portal's role in sharing information between the General and Supervisory Board, its committees and the Executive Board of Directors should be emphasised. With regard to regulations, the following should be highlighted: \- Articles of Association: Article 22 (1) (l); \- Internal Regulation of the Executive Board of Directors: Articles 5 (1) (e) and 10 (4); \- Internal Regulation of the General and Supervisory Board: Article 5 (c) and (e), and Article 11 (1) (a); Article 14 and Article 17; \- Internal Regulation of the Financial Matters/Audit Committee: Article 5 (1) (f), Article 10 (1) (a) and Article 13; \- Internal Regulation of the Remuneration Committee: Article 5 (1) (d); Article 10 (1) (a) and (2); \- Internal Regulation of the Corporate Governance and Sustainability Committee: Article 5 (e); Article 10 (1) (a), (2), and (3) (c); Articles 12 and 13; \- Internal Regulation of the United States of America (USA) Business Affairs Monitoring Committee: Article 5 (d); article 9 (1) (a). Items 21 to 45 Conflicts of Interest II.4.1. By internal regulation or an equivalent hereof, the members of the management and supervisory bodies and of the internal committees shall be obliged to inform the respective body or committee whenever there are any facts that may constitute or give rise to a conflict between their interests and the interest of the company. ADOPTED Since 17 May 2010, EDP has implemented rules for identifying internal reporting and acting in the event of a conflict of interest, applicable to all EDP Group employees who have a decision-making role in transactions with related parties. In 2021, and with the revision of internal regulations, the Transaction with Related Parties Policy came into force, which aims to establish the general principles of action and reporting in order to identify, prevent, detect, and resolve situations of conflicts of interest in the context of Transactions with Related Parties, which was revised in May 2023. In addition, it aims to contribute to the promotion of ethics and integrity in the development of the business of EDP and other compa- nies and/or entities that make up the EDP Group, ensuring compliance with legislation and established principles and rules. The Internal Regulations of EDP's governing bodies or committees also contain a provision according to which the members of these bodies and committees must inform the respective body or committee of facts that may constitute or give rise to a conflict between their interests and the corporate interest. Conflicts of interest are reported whenever there are facts that may constitute or give rise to them and are not limited to the deliberative context. All the Internal Regulations of the governing bodies and Specialised Committees include a specific provision on the conduct to be adopted by a member of the respective body or committee who is in a situation of actual or apparent conflict of interest, as well as a duty to provide information and clarification. The respective articles that specifically address this recommendation are as follows: \- Internal Regulation GSB: Article 10 \- Internal Regulation EBD: Article 6 \- Internal Regulation FMC/AUDC: Article 9 \- Internal Regulation REMC: Article 9 \- Internal Regulation CGSS: Article 9 \- Internal Regulation CAN: Article 8 Item 10 | Item 18 | Item 20 | Item 21 | Item 91 II.4.2. The company adopts procedures to ensure that the conflicted member does not interfere in the decision-making process, without prejudice to the duty to provide information and clarification requested by the body, committee or respective members. ADOPTED Item 10 | Item 18 | Item 20 | Item 21 | Item 91 

451 Part III Integrated Annual Report 2023 Corporate Governance Report REOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION Transactions with Related Parties II.5.1. The management body discloses, in the corporate governance report or by other publicly available means, the internal procedure for verification of transactions with related parties. ADOPTED In this regard, in addition to the provisions of the applicable legislation and the Articles of Association, there is an internal regulation on conflicts of interest and business between related parties, revised in May 2023 - the Related Party Transactions Policy - which can be consulted on EDP's website. Under the terms of the Articles of Association and the legislation in force, the Executive Board of Directors is responsible for the management of the Company and, for the purposes of transactions with related parties, the following are considered to be decision-makers: (i) the members of the governing bodies of EDP and its Subsidiaries; (ii) EDP employees in job grades 20 to 25, regardless of the EDP Group company with which they have a contractual relationship or perform duties; (iii) whenever the decision-maker defined in (ii) identifies, as decision-makers, other EDP Group employees, with a job grade lower than 20, to whom it has attributed identical competences; and (iv) whenever the Executive Board of Directors expressly qualifies EDP Group employees as decision-makers, indicating the respective scope of activity and delegation of competences. All decision-makers must therefore report any information deemed relevant on transactions carried out or to be carried out with related parties, namely with controlled companies or with the decision-makers themselves. The Related Party Transactions Policy also identifies deals of significant importance, specifying the type and scope of deals subject to prior authorisation. In addition, Article 17(2) of EDP's Articles of Association refers to a set of matters that are subject to the prior favourable opinion of the General and Supervisory Board, which must set the parameters for measuring the economic or strategic value of the operations that must be submitted to it for an opinion, particularly with regard to acquisitions and disposals of assets, rights or holdings of significant economic value, under the terms of Article 21(7) of EDP's Articles of Association and Article 15 of the Internal Regulations of the General and Supervisory Board. It is the responsibility of the General and Supervisory Board, within the scope of its assessment of EDP's annual and interim management report and considering the work carried out by the Financial Matters Committee/Audit Committee, to analyse and issue an opinion on the relevant business concluded between these parties. Effectively, EDP has a Specialised Committee of the General and Supervisory Board, the Financial Matters Committee / Audit Committee, with the power to assess business with related parties. Its Internal Regulations make it clear that the final decision rests with the General and Supervisory Board, in accordance with Article 12(1)(i) and (j). In addition, the Corporate Governance and Sustainability Committee is responsible for monitoring and supervising the systems for assessing and resolving conflicts of interest, particularly with regard to the company's relations with shareholders, by analysing the proposals for remedies for situations reported to it by the Financial Matters Committee/Audit Committee (Article 2(1)(d) of its Internal Regulations). EDP also has a set of rules regarding the issuing of a prior opinion by the General and Supervisory Board, as well as the procedures for communication and the provision of clarifications between the General and Supervisory Board and the Executive Board of Directors. In addition, the Executive Board of Directors must, no later than 20 (twenty) days after the end of each quarter, inform the General and Supervisory Board of all transactions that constitute relevant situations, and the elements that must be included in this information are referred to in the respective policy (in accordance with Article 22(1)(l) of the Articles of Association and Article 14(1)(k) of the Internal Regulations of the General and Supervisory Board). The intervention of the General and Supervisory Board in the assessment of this type of transaction is always preceded by the analysis and scrutiny of the Executive Board of Directors. Also under the terms of the Internal Regulations in force on this matter, the General and Supervisory Board and, more specifically, the Financial Matters Committee/Audit Committee, analyse all transactions between EDP and controlled companies with a value equal to or greater than: (i) 75 million Euros, in the case of shareholder loans and loans; (ii) 75 million Euros, in the case of acquisition, sale, marketing or supply of electricity or natural gas, as well as related services and products and (iii) 5 million Euros in all other cases. Item 10 | Items 89 to 92 CHAPTER III - SHAREHOLDERS AND GENERAL MEETING III.1. The company does not set an excessively large number of shares to be entitled to one vote [III.1. (1)] and informs in the corporate governance report of its choice whenever each share does not carry one vote [III.1. (2)]. ADOPTED [III.1.(1)] Article 14(1) and (2) of EDP's Articles of Association state that each share corresponds to one vote and that all shareholders with voting rights may participate in general meetings provided that they hold such rights on the date of registration. [III.1. (2)] – Not applicable. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 III.2. The company that has issued special plural voting rights shares identifies, in its corporate governance report, the matters that, pursuant to the company’s Articles of Association, are excluded from the scope of plural voting. NOT APPLICABLE The Company does not issue shares with special plural voting rights. Item 12 III.3. The company does not adopt mechanisms that hinder the passing of resolutions by its shareholders, specifically fixing a quorum for resolutions greater than that foreseen by law. ADOPTED The Article 11(3) of EDP's Articles of Association establishes that the decisions of the Annual General Shareholders’ Meeting shall be taken by a majority of the votes cast, unless a legal or statutory provision requires a qualified majority. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 III.4. The company implements adequate means for shareholders to participate in the general meeting without being present in person, in proportion to its size. ADOPTED Although EDP has always strived to maximise shareholder participation in general meetings, as such involvement provides direc t interaction with stake holders and thus constitutes a positive factor for proximity to the shareholder structure, for the efficient functioning of the Company and for the achievement of its corporate purpose, the Covid-19 pandemic context has inevitably changed this understanding. Since EDP held three Annual General Shareholders’ Meeting in a State of Emergency context, on 16 April 2020, 19 January 2021 and 14 April 2021, it was necessary to implement procedures for them to be held by telematic means, according to the respective notices available at General Meetings | edp.com. The constitutive quorum for the three aforementioned General Meetings was 67.3% for the April 2020 Annual General Shareholders’ Meeting, 73.9068% for the January 2021 Extraordinary Annual General Shareholders’ Meeting and 74.415% for the April 2021 Annual General Shareholders’ Meeting. For the exceptional reasons explained above, the form of voting corresponded exclusively to voting by 

452 Part III Integrated Annual Report 2023 Corporate Governance Report REOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION correspondence, either by post or electronically, under the terms of article 384, paragraphs 8 and 9 of the Companies Code, article 22 of the Securities Code, and under the terms of article 14, paragraphs 6 and 8 of EDP's Articles of Association. The fact that the Annual General Shareholders’ Meeting were held exclusively by telematic means meant that all shareholders registered and duly authorised to participate in the Annual General Shareholders’ Meetings had access to live video and audio broadcasts of the meetings. To this end, a link was sent the day before the Annual General Shareholders’ Meetings to the email address provided when the shareholder or their representative expressed their intention to attend the Annual General Shareholders’ Meetings, so that they could access a digital platform. In addition to the possibility of asking questions in writing via the digital platform about the topics on the Agenda that they wished to be answered at the me eting, held by telematic means, under the terms of article 290 of the Companies Code, shareholders were given the opportunity to ask questions in writing up to two (2) days before the respective dates of the Annual General Shareholders’ Meetings. For the Extraordinary Annual General Shareholders’ Meeting of 19 January 2021, the Annual General Shareholders’ Meeting of 14 April 2021, the Annual General Shareholders’ Meeting of 6 April 2022 and the General Meeting of 12 April 2023, and in order to ensure full clarification for shareholders prior to exercising their voting rights, and without prejudice to the timely availability of documents relating to the Items on the Agenda and the prerogative conferred above, shareholders were given the opportunity to ask questions, under the right to information provided for in art icle 290 of the Commercial Companies Code. The shareholders were given the opportunity to ask questions, under the right to information provided for in article 290 of the Commercial Companies Code, up to 8 (eight) days before the Annual General Shareholders’ Meeting, so that any questions they had prior to exercising their voting rights could be fully clarified. At the Annual General Shareholders’ Meetings of 6 April 2022 and 12 April 2023, EDP implemented a hybrid model, giving shareholders the option of attending the Annual General Shareholders’ Meeting in person or by telematic means. III.5. The company also implements adequate means for the exercise of voting rights without being present in person, including by correspondence and electronically. ADOPTED If, on the one hand, EDP's Articles of Association make it possible to exercise postal voting by letter (article 14, paragraph 6), on the other hand, they allow and determine the procedure for exercising postal voting rights, including by electronic means, in accordance with requirements that ensure their authenticity (article 14, paragraphs 6 to 8). As provided for in the notice of the Annual General Shareholders’ Meetings held on 12 April 2023, the right to vote may be exercised in one of the following ways: (i) advance electronic vote, or (ii) postal vote, or (iii) electronic vote during the Annual General Shareholders’ Meetings (telematic assistance) or (iv) in-person vote during the Annual General Shareholders’ Meetings. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 III.6. The Articles of Association of the company that provide for the restriction of the number of votes that may be held or exercised by one single shareholder, either individually or jointly with other shareholders, shall also foresee that, at least every five years, the general meeting shall resolve on the amendment or maintenance of such statutory provision – without quorum requirements greater than that provided for by law – and that in said resolution, all votes issued are to be counted, without applying said restriction. NOT ADOPTED Given the company's current shareholder structure, this recommendation has no practical applicability. However, in recent years, the issue of the statutory limitation on voting rights has already been considered by EDP's General Meeting three times, the last of which took place on 24 April 2019\. The shareholders have thus been called upon to give their opinion on the limitation of the number of votes, and there has been significant support for maintaining the existence of the limitation and reflection on adjusting the relevant ceiling for counting voting rights, precisely in the direction of a progressive increase in this level. The company's shareholder dynamics have thus proved to be perfectly in tune with the direction advocated in the Recommendation and sufficiently capable of pursuing its objectives, dispensing with rigid formulas for the statutory provision of this revision, which has even fostered particularly intense shareholder scrutiny of this clause, without constituting an impediment to the regular functioning of the corporate control market. These circumstances confirm that the voting cap does not prevent the relevant involvement of shareholders in EDP's corporate governance, and it is true that there were 3 resolutions at the General Meeting, from 2011 to 2019, related to this statutory limitation. In effect, the limitation on the number of votes provided for in Article 14 of the Articles of Association reflects the express will of EDP's shareholders through resolutions in defence of the Company's specific interests. In effect, the limitation on the number of votes provided for in Article 14 of the Articles of Association reflects the express will of EDP's shareholders through resolutions of the General Meeting, in defence of the Company's specific interests: (i) the change in the aforementioned limit from 5% to 20% was approved by the shareholders at the General Meeting of 25 August 2011, in which 72.25% of the share capital was held and the approval was carried out by a majority of 94.16% of the votes cast; (ii) the subsequent increase to the current 25% was approved at the General Meeting of 20 February 2012, in which 71.51% of the share capital was held and approval was given by a majority of 89.65% of the votes cast; and (iii) the unsealing of the Articles of Association, in which 64.29% of the share capital was held and this change was rejected by a majority of the votes cast, with 56.61% voting against. III.7. The company does not adopt any measures that require payments or the assumption of costs by the company in the event of change of control or change in the composition of the management body and which are likely to damage the economic interest in the transfer of shares and the free assessment by shareholders of the performance of the Directors. ADOPTED As provided for in EDP's Corporate Governance Manual, there are no known measures that have the effect of jeopardising the free transferability of shares and the free assessment by shareholders of the performance of the members of the management body. Likewise, EDP has not entered into any significant agreements that come into force, are amended or terminate in the event of a change of control of the Company following a takeover bid, with the exception of normal market practice with regard to the issue of debt. In fact, EDP is usually a party to financing contracts and issuers of bonds that include change of control clauses, which are typical of such contracts and securities and appear to be necessary for the realisation of the transactions, and their existence is not considered likely to harm the economic interest in the transfer of EDP's shares, nor the free assessment by shareholders of the performance of directors. In addition, with regard to any measures adopted that determine payments or the assumption of charges by the Company in the event of a change in the composition of the management body, apart from the situations set out in the Remuneration Report, there are no contracts in force at EDP that provide for payments in the event of dismissal or termination by agreement of the duties of a director, nor any other measures that determine payments or the assumption of charges by EDP in the event of a change in the composition of the management body.

454 Part III Integrated Annual Report 2023 Corporate Governance Report REOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION V.1. With due regard for the competences conferred to it by law, the supervisory body takes cognisance of the strategic guidelines [V.1. (1)] and evaluates and renders an opinion on the risk policy, prior to its final approval by the administration body [V.1. (2)]. ADOPTED Within the scope of the corporate governance model in force at EDP, the General and Supervisory Board also has a particularly important competence. In fact, although it does not have management powers, under the terms of Article 442(1) of the Companies Code, Article 17(2) of the Articles of Association establishes that the approval of EDP's strategic plan and the carrying out, by EDP or by companies controlled by EDP, of the following operations are subject to the prior favourable opinion of this corporate body (also in accordance with Article 15 of the Internal Regulations of the General and Supervisory Board): (i) acquisitions and disposals of assets, rights or shareholdings of significant economic value; (ii) contracting of financing of significant value; (iii) opening or closing of establishments or important parts of establishments and important extensions or reductions in activity; (iv) other businesses or operations of significant economic or strategic value; (v) establishment or termination of strategic partnerships or other forms of lasting co-operation; (vi) demerger, merger or transformation projects; and (vii) amendments to the Articles of Association, including the change of registered office and capital increase, when these are at the initiative of the Executive Board of Directors. In addition, the General and Supervisory Board, within the scope of its competences, takes cognisance of the Company's strategic lines, in accordance with the provisions of articles 14, no. 1 and 17, no. 9 of its Internal Regulations. It is also worth mentioning the specific competences of the Financial Matters Committee/Audit Committee in relation to financial matters and accounting practices, internal auditing practices and procedures, the mechanisms and internal procedures of the Internal Control System for Financial Reporting (SCIRF), matters relating to the risk management and control system, the activities and mechanisms of the compliance management system and the activity and independence of the Statutory Auditor/Firm of Statutory Auditors. The Financial Matters Committee/Audit Committee is responsible for monitoring, on an ongoing basis, the assessment of internal procedures relating to the effectiveness of the risk management system, internal control and internal audit systems, and must assess and comment on the EDP Group's strategic guidelines [V.1. (1)] and corporate risk management policy prior to their final approval by the Executive Board of Directors [V.1. (2)], under the terms of Article 12.2 i) of the FMC/CAUD Internal Regulations. The General and Supervisory Board is also involved in the EDP Group's Business Plan, implicitly ensuring alignment between management and shareholders with regard to the Group's risk appetite. The General and Supervisory Board is also regularly informed of key risk indicators in line with performance metrics, which allow it to monitor the evolution of the company's risk profile. Item 21 | Item 24 | Item 29 | Items 49 to 55 V.2. The number of members of the supervisory body [V.2. (1)] and of the financial matters committee [V.2. (2)] should be adequate in relation to the size of the company and the complexity of the risks inherent to its activity, but sufficient to ensure the efficiency of the tasks entrusted to them, and this adequacy judgement should be included in the corporate governance report. ADOPTED [V.2 (1)] The General and Supervisory Board is made up of a minimum of 9 members, but always more than the number of directors, pursuant to Article 21(1) of the Articles of Association. [V.2 (2)] In turn, the Financial Matters Committee/Audit Committee will be made up of a minimum of 3 independent members in accordance with article 3 of the Internal Regulations of the Financial Matters Committee/Audit Committee, which in both cases is entirely proportional to the characteristics of the Company. Item 15 | 17 | Item 21 | Item 29 CHAPTER VI - PERFORMANCE ASSESSMENT, REMUNERATION AND APPOINTMENTS Annual Performance Assessment VI.1.1. The management body – or committee with relevant powers, composed of a majority of non-executive members – evaluates its performance on an annual basis [VI.1.1. (1)], as well as the performance of the executive committee [VI.1.1. (2)], of the executive directors and of the company committees [VI.1.1. (3)], taking into account the compliance with the strategic plan of the company and of the budget, the risk management, its internal functioning and the contribution of each member to that end, and the relationship between the bodies and committees of the company. ADOPTED [VI.1.1.(1)] Under the terms of Article 5(4) of the Internal Regulations of the Executive Board of Directors, the Chairman of this Board must ensure the adoption of appropriate mechanisms for the annual assessment of the functioning of the Executive Board of Directors and the performance of each of its members. It should be reiterated that, in fulfilment of the above, EDP has voluntarily set up a formal and objective process for evaluating the activity of the Executive Board of Directors, which makes it possible to assess the degree of compliance with the measures adopted. This is a distinctive practice adopted by the General and Supervisory Board, which is in line with the assessment criteria of the Dow Jones Sustainability Index and corresponds to the recognition of the continued endeavour for excellence in corporate governance practices that the General and Supervisory Board and the Executive Board of Directors have been developing. It should be noted that this entire assessment process, namely the content, format of the questionnaire and the respective conclusions, was analysed and certified by an external consultant. At the beginning of each year, the members of the General and Supervisory Board are invited to fill in a questionnaire during an interview, in order to gauge their personal perception of the performance of the Executive Board of Directors. This questionnaire analyses the following dimensions: (i) composition and organisation; (ii) the performance of the Executive Board of Directors in its activity; (iii) the relationship between the Executive Board of Directors and the General and Supervisory Board; (iv) the relationship between the Executive Board of Directors and other interlocutors. The purpose of the questionnaire is to provide an objective basis for reflection, which can be used by the General and Supervisory Board for the purposes of drawing up the evaluation opinion of the Executive Board of Directors, which is then presented to EDP's shareholders for a vote. This evaluation can be found in the Annual Report of the General and Supervisory Board - Statement on the Evaluation Process of EDP's Executive Board of Directors. Item 21 | Item 24 e 25 | Item 27 | Item 29 | Item 52 | Item 54 | Remuneration Report Remunerations VI.2.1.

In turn, the Remuneration Report identifies the amounts of all the Company's charges related to the duties of the governing bodies and respective specialised committees of the Company in the financial year in question, based on the Remuneration Policy approved for the term in question. Item 29 | Items 69 to 88 | Remuneration Report VI.2.4.

Within the budget constraints of the company, the remuneration committee may freely decide to hire, on behalf of the company, consultancy services that are necessary or convenient for the performance of its duties. ADOPTED Both the Remuneration Committee of the General and Supervisory Board and the Remuneration Committee appointed by the General Shareholders' Meeting freely decide on the hiring by the Company of consultancy services that are necessary or convenient for the performance of their duties, and this prerogative is provided for in article 4.6 of the Internal Regulations of the Remuneration Committee of the General and Supervisory Board and in articles 4.4 and 4.5 of the Internal Regulations of the Remuneration Committee appointed by the General Shareholders' Meeting.

Item 29 | Item 67 | Remuneration Report VI.2.6. The remuneration committee ensures that such services are provided independently. ADOPTED In accordance with Article 4 (5) of its Internal Regulations, the Remuneration Committee of the General and Supervisory Board ensures that consultancy services on remuneration matters are provided independently and that the respective providers will not be contracted to provide any other services to the Company itself or to others in a controlling or group relationship with it without the express authorisation of this Specialised Committee. In accordance with Article 4(5) of its Internal Regulations, the Remuneration Committee appointed by the General Meeting ensures that consultancy services on remuneration matters are provided independently and that the respective providers will not be contracted to provide any other services to the Company itself or to others in a control or group relationship with it without the express authorisation of the Committee. Item 29 | Remuneration Report VI.2.7. The providers of said services are not hired by the company itself or by any company controlled by or in group relationship with the company, for the provision of any other services related to the competencies of the remuneration committee, without the express authorisation of the committee. ADOPTED Item 29 | Remuneration Report VI.2.8. In view of the alignment of interests between the company and the executive directors, a part of their remuneration has a variable nature that reflects the sustained performance of the company and does not encourage excessive risk-taking. ADOPTED The fulfilment of this recommendation can be found in Item 69 of this chapter and in the Remuneration Report (Part IV). Items 69 and 70 | Remuneration Report VI.2.9. A significant part of the variable component is partially deferred over time, for a period of no less than three years, and is linked to the confirmation of the sustainability of performance, in terms defined in the remuneration policy of the company.

The company promotes, in the terms it deems adequate, but in a manner susceptible of demonstration, that the proposals for the appointment of members of the corporate bodies are accompanied by grounds regarding the suitability of each of the candidates for the function to be performed. ADOPTED The Selection Policy for members of the General and Supervisory Board and the Executive Board of Directors in force, in line with best practice, aims to establish transparent and objective selection processes. The appointment of the members of the General and Supervisory Board and the Executive Board of Directors - although this is the responsibility of the General Meeting - is the result of an objective and transparent selection process that assesses the suitability of the candidates, individually and collectively, considering the legal and statutory competences of these governing bodies. Within the scope of the selection process, the integration of diverse skills, professional experience, diversity of knowledge, gender and cultures must be ensured, taking into account the specificities of the Company's business. The proposals for electing the members of the General and Supervisory Board and the Executive Board of Directors must be submitted to the General Meeting, duly substantiated, so that the shareholders can verify the suitability of the candidates' profile, knowledge and CV for the duties they are to fulfil. It is also worth highlighting the competences specifically provided for in the Internal Regulations of the Corporate Governance and Sustainability Committee, which give it the power to monitor, in coordination with the Executive Board of Directors, the definition of selection criteria, the establishment of the competences necessary for the structures and internal bodies of the Company, the Subsidiaries, as well as other entities in relation to which the Company has the right to appoint the members of the governing bodies, and their repercussions on the respective composition, in conjunction with EDP's Selection Policy and the criteria enshrined therein of merit, suitability for the position and diversity.

ADOPTED In 2023, EDP began the process of preparing the Company for sustainability reporting under Directive (EU) 2022/2464 of the European Parlia- ment and of the Council of 14 December 2022 - Corporate Sustainability Reporting Directive (CSRD). EDP began implementing an Internal Control System for Sustainability Information, promoting the interdisciplinary involvement of various organisational units in order to have a for- malised control system to prevent future risks and detect existing gaps. Although EDP has had a sustainability governance model for several decades, in 2006, with the adoption of a dual governance model, the General and Supervisory Board was set up to monitor and supervise EDP's management, as well as a specialised committee - the Corporate Governance and Sustainability Committee - with the mission of permanently monitoring and supervising matters relating to sustainability in all its dimensions. Although EDP has had a sustainability governance model for several decades, in 2006, with the adoption of a dual governance model, the General and Supervisory Board was set up to monitor and supervise EDP's management, as well as a specialised committee - the Corporate Governance and Sustainability Committee - with the mission of perma- nently monitoring and supervising matters relating to sustainability in all its dimensions. Therefore, under the terms of article 12.1 d) of the respective Internal Regulations, it is the responsibility of the Corporate Governance and Sustainability Committee to support and monitor the definition of sustainability policies and strategies, and their scope and extension to the social, economic and environmental aspects of the com- pany, as well as their implementation, making any recommendations deemed appropriate to the General and Supervisory Board and the Executive Board of Directors. In turn, the Executive Board of Directors is supported in the management of its activities by the Sustainability Cor- porate Global Unit and the Sustainability Committee, whose main duties are to (i) share information and discuss the implications of the main legislative packages on sustainability, (ii) share the evolution of the Group's ESG performance indicators and the respective benchmarks, (iii) discuss and issue an opinion on the development and updating of the sustainability policies of the Group's companies, (iv) discuss and issue an opinion on the annual action plans, as well as on the objectives and targets to be achieved by the EDP Group and (v) monitor the development of the approved action plans and the activities of the sustainability management structures of the EDP Group's companies. Sustainability in the EDP Group is organised with the aim of establishing close communication between the corporate structure and the functional structures, enhancing the flow of information and the operationalisation of its strategy, and its organisation is described on the respective corporate website. Item 21 | Items 50 to 55 | Management Report in the sustainability section VII.8. The company reports on how climate change is considered within the organisation and how it takes into account the analysis of climate risk in the decision-making processes. ADOPTED The Annual General Shareholders’ Meeting of EDP of 12 April 2023 considered the Climate Transition Plan, through which the Company commits to achieving Net-Zero by 2040, reducing its CO2 emissions by 90% in absolute terms compared to the base year 2020, including scopes 1, 2 and 3, based on the description of climate metrics and targets, the global climate governance in place and the identification of strategic levers to align implementation with global climate commitments. On a quarterly basis, EDP informs the market and the general public about the progress of this plan for key CO2 indicators through its ESG Report and, annually, in the Integrated Report with a broader stakeholder approach. The monitoring of the objectives is carried out and disclosed in the Management Report, Sustainability section (climate change and promotion of renewable energies), and the monitoring of the implementation of the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) is described in the climate risk management section. The climate transition is intrinsic to EDP's business, with an internal governance model established to ensure a resilient climate strategy, its effective implementation and a monitoring system capable of tracking performance efficiently. In this regard, the General and Supervisory Board supervises the implementation of EDP's Climate Strategy through its Corporate Governance and Sustainability Committee, which is responsible for discussing ESG topics between three and four times a year, with Climate being at the top of this agenda. The remuneration policy for the members of the Executive Board of Directors, proposed by the Remuneration Committee of the General and Supervisory Board and approved by the General Meeting at least every four years, establishes a fixed component and a variable component, the latter including ESG key performance indicators (KPIs), including the Climate KPI, which are aligned with the Company's current Business Plan and are applicable for the 2021-2023 term of office, including, namely, EDP's performance in the Dow Jones Sustainability Index, the CO2 intensity reduction target, the installed renewable energy capacity, aligned with public commitments, and the performance of the Bloomberg Gender Diversity Index. The Executive Board of Directors plays a central role in approving the EDP Group's Business Plan, as well as in its execution, forecasting the decarbonisation path, supported by a global risk management process aligned with different climate scenarios. Before approval, the sustainability strategy is prepared by the Sustainability Corporate Global Unit, supported by the Risk and Energy Planning Departments. In addition, with the involvement of the main Business Units, the Sustainability Committee discusses the proposed sustainability strategy before it is approved. To highlight the role and impact of EDP's climate strategy, a Net Zero Acceleration Programme (NZAP) was created as part of the Climate Transition Plan. Management Report in the sustainability section | Annual Report of the General and Supervisory Board VII.9. The company informs in the corporate governance report on the manner in which artificial intelligence mechanisms have been used as a decision-making tool by the corporate bodies. ADOPTED EDP does not have an automatic advisory mechanism for decision-making by the governing bodies. Nevertheless, it should be noted that the company takes advantage of data, analytics and artificial intelligence practices applied in various aspects of its activity: (i) business and services for final customers, (ii) optimisation and technical decision support for the assets that EDP manages, (iii) management support decisions based Management Report in the sustainability section

The company remains committed to closely monitoring the evolution of the artificial intelligence market, as well as emerging trends in the use of artificial intelligence in decision-making processes. EDP is committed to maintaining a proactive stance, closely monitoring technological innovations and developments in this field. This is realised through multidisciplinary teams comprising technology, business, ethics, legal and compliance experts. It should also be noted that EDP approved, in 2023, the Policy for the Use of Generative Artificial Intelligence (AI) Applications in the EDP Group, with the main objective of establishing a set of guidelines to be followed in the use of AI applications for professional use, based on principles applicable to all users, with a view to guaranteeing the safe, compatible and reliable use of these applications.

494 Part IV Integrated Annual Report 2023 Remunerations Report This Remuneration Report aims to provide a comprehensive and integrated description of the remuneration earned by the members of the governing bodies and bodies of EDP – Energias de Portugal, SA (“EDP” or “Company”), including all benefits, regardless of the respective form, attributed or due during the 2023 financial year. As provided for in the EDP Articles of Association, the remuneration of the members of the governing bodies is fixed by a Remuneration Committee appointed by the General Meeting, with the exception of the remuneration of the members of the Board of Directors Executive Board, which is set by a Remuneration Committee appointed by the General and Supervisory Board. Until the changes resulting from the General Meeting held on 14 April 2021, these Committees submitted annually to the General Shareholders’ Meeting a declaration on the remuneration policy of the members of the governing bodies, pursuant to the provisions of paragraph 1 of article 2 of Law no. 28/2009, of 19 June. With the entry into force of Law no. 50/2020, of 25 August, which transposed Directive (EU) no. 2017/828 of the European Parliament and of the Council of 17 May 2017, the Remuneration Committee is responsible to submit to the Company's General Shareholders’ Meeting a proposal for a Remuneration Policy for the Members of the Governing Bodies. Following the General Meeting held on 14 April 2021, the proposal for the conformation of EDP's Articles of Association was approved the proposal of the Remuneration Policy for the members of the governing bodies submitted by the Remuneration Committee appointed by the General Meeting, the proposed Remuneration Policy of the members of the Executive Board of Directors, which was submitted by the Remuneration Committee appointed by the General and Supervisory Board, by respectively 98.69% and 98.58% of the votes cast. On 12 April 2023, EDP’s General Meeting considered the Remuneration Report under the item on the approval of the Integrated Annual Report, which was approved by the majority of votes cast (98.35% in favour). 1 For more information, see previous Remuneration Reports of EDP as well as the Remuneration Policy Statement submitted to the General Shareholders’ Meeting from April 16 th 2020 A. Remuneration policy applicable to members of the Executive Board of Directors approved by the Remuneration Committee appointed by the General and Supervisory Board Procedures for adopting the policy Until the General Shareholders’ Meeting held on 14 April 2021, the definition of the remuneration policy for the members of the management body was defined by the Remuneration Committee appointed by the General and Supervisory Board, which established a fixed component and a variable component. Regarding the variable component, this Committee established the remuneration to be awarded to the directors, seeking to ensure that it reflected the performance of each of the members of the Executive Board of Directors in each year of the mandate (annual variable remuneration), as well as their performance for the entire term of office, by setting a variable component consistent with maximizing EDP's long-term performance (multi-annual variable remuneration). The remuneration policy was revised annually 1 and, with the same periodicity, was subject to the General Shareholders’ Meeting appreciation. At the General Shareholders’ Meeting held on 14 April 2021 approved the proposed Remuneration 2 Policy for the members of the Executive Board of Directors, drawn up and submitted by the Remuneration Committee appointed by the General and Supervisory Board. As stated in the Remuneration Policy for the members of the Executive Board of Directors, drawn up under the terms of Law no. 50/2020, of 25 August and considering the Corporate Governance Code of the Portuguese Institute of Corporate Governance (IPCG) adopted by EDP, the Remuneration Committee of the General and Supervisory Board considered that it was appropriate to review the Remuneration Policy of the Executive Board of Directors in view of the start of the mandate of a new Executive Board of Directors, the approval of a new business plan and the feedback received from analysts and investors on the remuneration system of the Executive Board of Directors. The proposal for the Remuneration Policy of EDP's Executive Board of Directors resulting from this review was submitted and approved at EDP's General Shareholders’ Meeting of 14 April 2021. The policy review work that gave rise to the proposal presented to the General Shareholders’ Meeting was also based on the conclusions of a study requested by the 2 For more information, see: Remuneration Policy approved at the General Shareholders Meeting of April 14th 2021 

495 Part IV Integrated Annual Report 2023 Remunerations Report Remuneration Committee of the General and Supervisory Board and carried out by an independent consultant, as well as on the advice obtained by the aforementioned Committee in relation to corporate governance matters, good international practices and, in general, the matter of remuneration policy as an instrument to promote the business strategy and the long-term and sustainability interests of EDP, provided by a law firm, based on a benchmark analysis of the remuneration model, both qualitative and quantitative, of companies in the PSI 20 Index and comparable companies in the international electricity sector. In the proposed Executive Board of Directors' Remuneration Policy, the evolution of the remuneration system for directors and other EDP employees, the reduction in the number of members of the Executive Board of Directors, with the functional reorganization of that Board and consequent increase in responsibilities resulting therefrom, in particular for the global lower remuneration level of the Executive Board of Directors, also taking into account the reasonable expectations of its members, elected in January 2021, regarding the remuneration model and its adequacy and competitiveness. The consideration of employment conditions and the remuneration model for EDP's workers and the economic and financial situation in the country and worldwide also contributed to this end. In fact, the consideration of these elements advised that, on that occasion, and without prejudice to the reduction in the number of levels of fixed remuneration of the members of the Executive Board of Directors, as described below, no further review of the fixed component of the remuneration should be carried out. of the members of the Executive Board of Directors, with the impact that such an option has on the other components of the remuneration, although from the point of view of analysing the functions of the current five members of the Executive Board of Directors and the sector benchmark, such a review could prove to be appropriate. EDP, as the apex of a responsible multinational business group (“Group”) has a solid governing culture that ensures the management, monitoring, control, and supervision of the risks that the Group, its shareholders, employees, customers and, in general, all its stakeholders face, including those arising from the remuneration systems it adopts. EDP adopts remuneration practices transversal to the Group, consistent and based on common principles, which comply with the regulations applicable in the jurisdictions where it carries out its activity. EDP's remuneration systems, including those of the Executive Board of Directors, are defined to promote a culture of merit and high performance that ensures that people and teams are recognized, encouraged and rewarded according to their responsibility, availability, loyalty and competence placed at the service of EDP, guaranteeing action in line with the long-term interests of shareholders and its stakeholders and the promotion of sustainable performance by EDP aligned with ESG (Environment, Social and Governance) objectives. The proposal for the Remuneration Policy for the members of the Executive Board of Directors was also aimed at simplification, transparency, and clarity, favouring a complete understanding of the framework of principles and rules that constitute it, which are applied by the Remuneration Committee of the General Board and Supervision. Definition, review, and renewal of the Policy The definition of the remuneration policy of the Executive Board of Directors is submitted for approval by the General Meeting of EDP, at the proposal of the Remuneration Committee of the General and Supervisory Board. Changes to the Internal Regulations of the Remuneration Committee of the General and Supervisory Board include the process of reviewing and applying the Remuneration Policy of the Executive Board of Directors, in accordance with the following principles: • the Remuneration Committee of the General and Supervisory Board meets at least once a semester in order to monitor the situation of EDP in relevant matters for the purposes of determining and fixing the variable remuneration of the Chairman of the Executive Board of Directors and the other Directors and for the analysis of relevant information that may justify the consideration of adjustments to the application of the Remuneration Policy, proceeding as necessary and convenient to the hearing of the Financial Matters Committee/Audit Committee and the Corporate Governance and Sustainability Committee of the General and Supervisory Board, of the Executive Board of Directors or any of EDP’s corporate body in terms of compliance, risk management and Human Resources; • the definition and possible proposals for reviewing the Remuneration Policy are based on the articulation of EDP's long-term objectives, measured according to its strategic plan at any given moment, on the conclusions of comparative remuneration studies with national listed companies and with peers’ foreign sectors and in an articulation of principles with the remuneration plan of other workers and employees of EDP; • on an annual basis, the Remuneration Committee of the General and Supervisory Board will assess the opinions expressed by shareholders and analysts on EDP's Remuneration Policy or on the Remunerations Report; • the Remuneration Committee of the General and Supervisory Board may hire the consultants and external support necessary to carry out studies on comparative remuneration and best corporate governance practices within the scope of 

496 Part IV Integrated Annual Report 2023 Remunerations Report remuneration policies for directors, assessing their independence conditions to the provision of services that may be requested. Without prejudice to (extraordinary) revision proposals, the Remuneration Committee of the General and Supervisory Board should, at least at the end of each term of office, when assessing compliance with the objectives set for the term in question, specifically analyse and decide on a reasoned basis, on the opportunity to propose the revision/update (ordinary) of the Remuneration Policy in any of its components, in order to ensure, at all times and with adequate agility, the fulfilment of the objective of the remuneration policy of retention and attraction of talent. The review of the base remuneration must also imply the weighting, according to benchmark criteria, of the total remuneration model practiced by comparable companies, in order to always ensure that the remuneration model of the members of the Executive Board of Directors of EDP remains balanced, fair, and competitive. Whenever a remuneration policy is proposed for reviewed, all relevant changes introduced will be described and how these changes reflect the votes and opinions expressed by shareholders on the remuneration policy, as well as the remuneration reports issued based on the aforementioned policy. Principles and General Characteristics The Remuneration Policy of the Executive Board of Directors of EDP aims to comply with the applicable legislation, also in terms of its content, under the terms of Article 26-C of the Securities Code, the IPCG Corporate Governance Code adopted by EDP and good international practices, being mutatis mutandis coherent and consistent with the remuneration policy and remuneration practices applied to Group employees. Regardless of the functions performed in companies of the Group, namely at EDP Renováveis, in accordance with the Remuneration policy of the members of the Executive Board of Directors, the members of this Board do not receive any remuneration or benefit from any other company of the Group, being exclusively remunerated through EDP. The remuneration of the members of the Executive Board of Directors must be aligned with the interests of shareholders, be focused on the creation of long-term value and be compatible with adequate and rigorous risk management, thus contributing to the Company's strategy, to its long-term values and interests and for its sustainability. Total remuneration and the remuneration model, in general, must be competitive, aligned with the practices of the international electricity sector and the market, facilitating the attraction and retention of talent, and the commitment to the company's challenges and ambitions. The competitiveness of the remuneration model/system of the Executive Board of Directors must be regularly and periodically assessed, namely through the analysis of the functions performed and benchmark exercises to be carried out with the support of independent entities, which is assumed to be done with a minimum triennial frequency, corresponding to the duration of the term-of-office of the Executive Board of Directors. The Executive Board of Directors' Remuneration Policy ensures a (fixed) base remuneration, the payment of which is not dependent on performance evaluation, which must be fair, competitive, and sufficiently relevant in relation to the total remuneration, in order to allow greater flexibility in the conformation of the variable component of the remuneration. The Remuneration Policy of the Executive Board of Directors comprises a variable remuneration, with an annual component, and a multi-annual component, with the nature of reward/incentive appropriate to the individual and collective performance of the members of the Executive Board of Directors and the promotion of good conduct, considering EDP's short- and long-term, financial, and non-financial objectives that are achieved, and the way in which they were achieved (pay for performance). The annual variable component is linked to financial and non-financial objectives established in accordance with EDP's Annual Budget, measured annually, with an impact on the year and subject to evaluation and consequent repercussion in the following years, being paid in cash. The annual variable remuneration must be determined after the approval of EDP's accounts at the Annual General Meeting each year, by reference to the previous year/period of annual performance. The payment of the annual variable remuneration is partially deferred. The multi-annual variable component is linked to the quantitative and qualitative objectives of EDP's Business Plan, the fulfilment of which will be evaluated at the end of a period of three years, with the respective payment subject to partial deferral. The multi- annual variable remuneration is paid exclusively in shares representing the share capital of EDP (“EDP Shares”). 

497 Part IV Integrated Annual Report 2023 Remunerations Report The determination of the variable annual and multi-annual remuneration of the members of the Executive Board of Directors in accordance with the Remuneration Policy is the responsibility of the Remuneration Committee of the General and Supervisory Board. The payment of the variable remuneration is subject to the permanence of the member of the Executive Board of Directors at EDP until the end of the annual or three-year period of relevant performance, without prejudice to the provisions of the Remuneration Policy. In the event that EDP or members of the Executive Board of Directors are responsible, by shareholders or third parties, for intentional unlawful acts of management, the annual and multiannual variable remuneration of the directors in question may, by decision of the Remuneration Committee of the General and Supervisory Board, be suspended or not awarded, until such claims are determined and, in case they are considered valid, the variable remuneration paid during the period of practice of the facts, overdue, or to be awarded, will be reimbursed, retained or not awarded for compensation for damages caused up to the full amount thereof (malus and clawback clauses). In assessing the annual and multi-annual performance of the members of the Executive Board of Directors and determining the amount of the variable remuneration due to them, the Remuneration Committee of the General and Supervisory Board may take into account exceptional circumstances affecting EDP, caused by decisions of a political or administrative nature beyond the control of the members of the Executive Board of Directors, which have an impact on EDP's performance and level of achievement of objectives, neutralizing their impacts on annual and multi-annual performance metrics, provided that it ensures that, in case of reversal of the decisions of a political or administrative nature in question, by means of an arbitration, judicial or arbitration procedure, the members of the Executive Board of Directors will also not benefit from the effects of such reversal decision. Likewise, the Remuneration Committee of the General and Supervisory Board may consider other exceptional conjunctural and exogenous circumstances that EDP is faced with, which have an impact on the Company's performance and the level of achievement of objectives set for its members. of the Executive Board of Directors, adjusting or justifiably adopting appropriate solutions to neutralize, for the benefit of EDP or the members of the Executive Board of Directors, as the case may be, in whole or in part, the impact of said consequences on annual and multi- annual performance metrics. In addition to some of the benefits provided to EDP employees, which the members of the Executive Board of Directors also benefit from, the members of this Board must also benefit, by virtue of the duties performed and in accordance with market practices and EDP's culture from a set of additional benefits, of a non-financial nature. As with EDP employees and in accordance with the legislation and Article 27(1) of EDP's Articles of Association, the Company must provide directors with a supplementary retirement pension due to old age or disability or, in its place, and in accordance with the practice consistently followed by the company, a retirement savings plan or equivalent instrument, namely a unit linked capitalization insurance. The Financial Matters Committee/Audit Committee and the Corporate Governance and Sustainability Committee of the General and Supervisory Board shall, together with the Remuneration Committee of the General and Supervisory Board and at its request, monitor the adequacy and application of the Policy of Remuneration of the Executive Board of Directors and other documents, namely of a regulatory nature that develop it, with a view to ensuring its compliance with the legislation and internal policies and risk culture of EDP, as well as evaluating its effects on the appetite for risk and how such effects are managed. The Remuneration Committee of the General and Supervisory Board ensures certification, by an independent entity, of the application of performance metrics in accordance with the approved Remuneration Policy. Without prejudice to a proposal for an extraordinary review during the term of office according to benchmark criteria, the Remuneration Policy will be valid for a period of three years (2021-2023) and will be the subject of a proposal for renewal or revision to be submitted to the General Meeting of EDP to be held in 2024. EDP’s Executive Board of Directors Members do not enter into contracts, either with the Company or with third parties, the effect of which is to mitigate the risk associated with the variability of the remuneration determined for them by the Company. Apart from the situations described in this Remuneration Report, there are no contracts in force at EDP that foreseeing payments in the event of dismissal or termination by agreement of the directors' duties. Components of the remuneration of the members of the Executive Board of Directors Fixed Component – Base Remuneration The base remuneration of the members of the Executive Board of Directors must be aligned with the base remuneration practiced by a group of companies comparable with Executive Board of Directors, of the national market (PSI 20 Index) and of the international electricity 

498 Part IV Integrated Annual Report 2023 Remunerations Report sector, in terms of size, market capitalization, risk profile, relevance and geographic implantation, also considering, at all times, the complexity of the functions performed, the remuneration conditions of EDP workers and the non-increase of the average remuneration gap of the market between workers and managers. Considering the reduction in the number of members of the Executive Board of Directors and the organizational / functional review of this structure with the consequent increase in responsibilities resulting therefrom, in particular the lower remuneration level of the Executive Board of Directors, the current Remuneration Policy has eliminated a remuneration level in the EBD, reducing, compared to the previous Remuneration Policy , from three to two, the levels of remuneration of the members of this Board, under the following terms: a. Annual base remuneration of the CEO: 800,000.00 Euros; and b. Annual base remuneration of the other members of the Executive Board of Directors: 560,000.00 Euros. The base remuneration of the members of the Executive Board of Directors is paid in 14 monthly instalments. Variable remuneration The variable remuneration of the members of the Executive Board of Directors is based on the success of the short and long-term performance of EDP, pursuant to the budget and business plan in effect, considering the performance of that Board and the individual performance of each member of the Executive Board of Directors, determined based on parameters of a financial and non-financial nature, individual and collective, absolute, and relative, in the terms indicated below. Annual Component The maximum annual variable remuneration may not be higher than 80% of the base remuneration in force in the year to which the referred annual variable remuneration refers, being determined, and falling due, after the approval of accounts for the year to which it relates. The annual variable remuneration has the nature of an incentive / performance bonus linked to short-term financial and non-financial objectives (linked to the business plan and budget), analysed annually, with a reflection on the year under evaluation and possible repercussions in the following years, being paid in cash. The amount of the annual performance bonus will be determined within three months after the approval of EDP's accounts at the Annual General Shareholders Meeting each year, by reference to the previous annual performance financial year/period. The annual variable component is limited to 80% of the base remuneration in force in the year to which the referred annual variable remuneration refers, being attributed according to the following parameters, calculated linearly: • If the performance reaches less than 85% of the defined objectives, there is no place for the attribution of an annual variable component; • If the performance achieved is between 85% and 95% of the defined objectives, an amount within the range of 10% and 25% of the fixed reference remuneration of each EBD member is due; • If the performance achieved is between 95% and 100% of the defined objectives, an amount within the range of 25% and 52.5% of the fixed reference remuneration of each EBD member is due; • If the performance achieved is between 100% and 110% of the defined objectives, an amount within the range of 52.5% and 80% of the fixed reference remuneration of each EBD member is due; • If the performance achieved reaches more than 110% of the objectives set, the amount corresponding to 80% of the reference fixed remuneration of each EBD member is due.

B. Remuneration policy applicable to members of the Governing Bodies approved by the Remuneration Committee elected by the General Meeting The Remuneration Committee elected by the General Meeting takes into account, for the purposes of the proposed remuneration policy for the members of the General and Supervisory Board, the Board of the General Meeting and the Statutory Auditor, the duties performed, the fixed nature of the remuneration, as well as the mandatory rules on their determination, in particular the provisions of number 2 of article 440 of the Commercial Companies Code, which explains the criteria for determining the remuneration of the General and Supervisory Board, in article 374-A of the Commercial Companies Code, in article 60 of Decree-Law no. 224/2008, of 20 November, on the remuneration of the Statutory Auditor. It is therefore incumbent upon the Remuneration Committee elected at the General Meeting to set the remuneration of the members of the following governing bodies: Board of the General Meeting, Chairman and members of the General and Supervisory Board, Statutory Auditor and the Environment and Sustainability Board. The Financial Matters Committee/Audit Committee is treated together with the other Specialized Committees of the General and Supervisory Board. Considering the competence of the Remuneration Committee elected at the General Meeting it only promotes the definition of fixed remunerations, so the legal determinations and others relating to variable remuneration, with their various dimensions, are not applicable here, without prejudice to the necessary alignment with the principles that shape EDP’s remuneration policies and, in particular, reflected in the EDP Business Plan for the period 2021-2025. Procedures for adopting the policy In the definition of the Remuneration Policy, proposals are made to ensure that remuneration is adequate, contribute to the business strategy and sustainability of EDP and reflect the risk profile and the long-term objectives and interests of EDP, showing still complying with legal norms, principles, and relevant national and international recommendations. The Remuneration Committee elected by the General Shareholders’ Meeting is also attentive to market references, following benchmark studies carried out in due course. Also in defining this policy, the Remuneration Committee elected by the General Meeting maintains interactions both with members of the relevant governing bodies and with the Company's stakeholders. As is the case of the Executive Board of Directors, the General and Supervisory Board and its Specialized Committees, the Remuneration Committee elected by the General Shareholders’ Meeting develops mechanisms for the prevention and management of conflicts of interest, under the terms set out in article 10 of the EDP Articles of Association, observing the following essential rules: i. When a member of the Remuneration Committee is in a situation of actual or apparent conflict of interest in a decision to be taken by this body, he must previously inform the Committee of the facts that may constitute or give rise to a conflict between his interests and the Social. ii. In the situation referred to in the previous number, the member of the Remuneration Committee must abstain from participating and voting at the meeting in which the topic is discussed and voted on, without prejudice to the duty to provide information and clarifications that the Committee or the respective members ask you. 

511 Part IV Integrated Annual Report 2023 Remunerations Report It should also be noted that, under the statutory terms, the Remuneration Committee elected by the General Meeting is composed of a majority of independent members. General Definition and Characterization When defining the remuneration policy presented by the Remuneration Committee and approved at the General Meeting, held on 14 April 2021, the following factors were considered: i. There is a renewal of the governing bodies with some depth, with the decrease in the number of members of the General Supervisory Board being highlighted; ii. Experience has shown that the functions are increasingly demanding and complex, which requires greater availability of this body, and it should be noted that, in 2020, instead of the eleven annual meetings that were usually held, there were nineteen; iii. The remuneration of the governing bodies, with the exception of the remuneration of the Chairman of the General Supervisory Board, has not changed since 2009, and in that year there was a reduction in relation to the 2006/2008 term of office; iv. Remuneration must also consider market comparables and be sufficiently attractive and adjusted to the responsibilities of the functions; v. The current remuneration of the members of the General Supervisory Board is, for the reasons mentioned above, well below market comparables, namely in the sector in which EDP operates. The proposed Remuneration Policy for the Members of the Governing Bodies aims to comply with the applicable legal provisions, and incorporate the corporate governance guidelines set out in the IPCG Corporate Governance Code adopted by the Company, framing within the guidelines that have been defined by the Company's reference shareholders, which are formulated in accordance with the aforementioned applicable rules and recommendations and with the best practices existing in the sector. It should be noted, as already mentioned, that the proposal for the Remuneration Policy for the Members of the Governing Bodies has a necessarily limited and reduced scope, since the definition of the remuneration policy for the members of the Executive Board of Directors is in charge of the Remuneration of the General and Supervisory Board. Therefore, are not within scope of the proposed Remuneration Policy does not include any variable remuneration to directors, remuneration based on shares or any other remuneration complement, a matter that is the responsibility of the Remuneration Committee of the General and Supervisory Board. For this reason, several legal provisions, concerning the referred matters, notably, those set forth in Article 26-C (3) (4) of the Portuguese Securities Code. Principles underlying the remuneration policy of the members of the Governing Bodies (excluding that of the Executive Board of Directors) The Remuneration Committee elected by the General Shareholder’s Meeting defined the remuneration policy for the members of the General and Supervisory Board, having as a guiding principles that it should be simple, transparent, moderate, and take into account the complexity and responsibility of the duties and the Company's economic situation, as well as being competitive and equitable, in order to guarantee the purpose of creating value for shareholders and other stakeholders. The Remuneration Committee elected by the General Shareholders’ Meeting based its decisions on remuneration policy on the following main guiding principles: i. Definition of a simple, clear, understandable, transparent policy in line with EDP's culture, so that the remuneration practice can be based on uniform, consistent, fair, and balanced criteria. ii. Definition of a policy consistent with effective risk management and control, to avoid excessive exposure to risk and conflicts of interest and seeking consistency with the Company's long-term objectives and values. iii. Evaluation and encouragement of a judicious action in which merit must be duly rewarded, ensuring levels of homogeneity compatible with the necessary cohesion of the General Supervisory Board, while also considering the economic and financial situation of the company and the country, even though EDP operates on a global scale. iv. Alignment of the remuneration of the various members of the governing bodies by companies with the highest market capitalization and European counterparts, naturally adapted to the Portuguese market. v. The most recent recommendations issued by the European Union and the Securities Market Commission. vi. Alignment of remuneration with the specific responsibilities inherent to the position in question. vii. Alignment of remuneration with the time required to spend in each position. 

512 Part IV Integrated Annual Report 2023 Remunerations Report viii. Simplification of the remuneration policy. Structure of the remuneration policy for the members of the Governing Bodies (excluding that of the Executive Board of Directors) Based on these criteria and considering the challenges that the Company intends to pursue during the term of office 2021-2023, the Remuneration Committee elected by the General Meeting decided that the following guidelines should apply: • A distinction must be maintained between the remuneration attributed to the members of the General Supervisory Board and those fixed to the members of the Executive Board of Directors, with the former not being allocated a variable remuneration component or any other remuneration supplement. • The performance with merit and the complexity of the functions performed by the members of each body must be considered, so that the cohesion, stability, and development of the Society are not jeopardized. • Regarding the Chairman of the General Supervisory Board, it must be considered that the functions require great availability and include a strong component of institutional representation. He may also chair the Financial Matters Committee/Audit Committee, without additional remuneration. • If the chairmanship of the Financial Matters Committee/ Audit Committee is assigned to another member of the General Supervisory Board, other than its Chairman, he/she must have a compatible remuneration, depending on the responsibility of the position and the requirement of availability. • In any case, the Chairman of the General Supervisory Board, or the Chairman of the Financial Matters Committee/Audit Committee, if they are separate persons, may not accumulate any other remuneration in relation to the basis assigned to them. • It is also important to differentiate the performance of other specific functions, within the scope of the General Supervisory Board, namely the participation of members of the General Supervisory Board in other committees, as well as the functions performed in these committees. • Finally, it should be considered that, historically, the remuneration of the Chairman of the Board of the General Meeting is similar to the remuneration attributed to the Chairman of a Committee. For this reason, the remuneration of the Chairman of the Board is aligned accordingly, and his inherent membership of the position of Member of the General Supervisory Board is also considered. C. Specifics applicable to the remuneration of the members of the General and Supervisory Board In compliance with the provisions of article 440 of the Commercial Companies Code, the remuneration of the members of the General and Supervisory Board is of a fixed nature, considering the duties performed. The remuneration policy currently in force was approved at the General Shareholders’ Meeting held on 14 April 2021. The remuneration of the Chairman of the General and Supervisory Board was set considering, namely, the necessary availability for the performance of his duties as well as the important component of institutional representation required. The remuneration of the Chairman of the General and Supervisory Board also includes the costs associated with the use of the vehicle and its driver. Remuneration limits Accordingly, and considering the aforementioned, the Remuneration Committee elected by the General Shareholders’ Meeting submitted to the shareholders the proposal for the gross remuneration of the members of the governing bodies identified below, for the financial year that began on 14 April 2021 and until the term of office, under the terms that follow: GENERAL AND SUPERVISORY BOARD ANNUAL REMUNERATION CHAIRMAN OF THE GENERAL AND SUPERVISORY BOARD: EUR. 515,000.00 Member of the General and Supervisory Board: EUR. 70,000.00 Financial Matters Commission/Audit committee: the following values add to the base remuneration

GRI Standards reporting principles Reporting quality Balance The content of the Report considers both the most positive facts of the year and those less positive when materially relevant. Comparability The information reported covers a four-year time series in the material topics indicators relevant to the EDP group's business (2.2. Materiality) and enables a comparative analysis of the company's performance. Transparency An online glossary is provided in Annex 7. Glossary. helping to understand some of the technical terms used. In addition to the publications in pdf, a web version is also available, facilitating navigation through the different contents. Accuracy The scope of the Report is explained, as well as the consolidation criteria. All exceptions and changes to criteria are duly identified and highlighted. The definitions and descriptions of the calculation methodologies of the main indicators employed are available online, in the glossary. Timeliness The Report has an annual frequency and covers the calendar year 2023. Reliability The internal process verification is described in this page, under ‘Internal and external assurance’. External verification is an additional guarantee of the reliability of the content, regarding the indicators included in GRI Table. Content principles Sustainability context Within the framework of the defined strategy, EDP fosters a corporate culture of permanent demand for excellence in sustainability. The group's sustainability performance is globally reported based on the consolidation criteria defined and described in the next point. Regarding the subsidiary companies, the group defines a clear strategy for continuous improvement of its performance, supported by the internal process of identifying the year's material issues and emerging trends in the sector, always considering the local conditions in which it operates. Regarding the jointly controlled companies, the group positively influences its performance and highlights the major initiatives of the year throughout the Report, when materially relevant. In the supply chain, the approach is management, and the material issues are published. In this context, the group advocates a relationship supported in trust, collaboration and shared value creation (3.4.7. Supply chain). Finally, on the customer side, EDP has a growth strategy supported by an increasingly clean supply, contributing to higher energy efficiency through decarbonization solutions (3.4.1. Climate change | Decarbonizing the world). Consolidation criteria The consolidation criteria of non-financial information are as follows: • in the subsidiary companies where the group exercises control, the performance of companies is reported at 100% • in jointly controlled companies and where the group exercises significant influence, the operational, environmental and social information is published, given its relevance to the group. 

521 Part V Integrated Annual Report 2023 Annexes | Annex 2. Reporting principles A list with the companies and the respective consolidation method is available in Part II – Financial statements and notes. Included in this list is the company Iberenergia, S.A.U. in which the group has a 100% holding and which is consolidated by the full consolidation method. This company owns 15.5% of Trillo Nuclear Power Plant and as EDP is a minority shareholder it does not exercise operational control or have the power to make financial decisions, through the limited percentage it owns of this power plant. Given this, EDP does not report on operational, environmental and social information regarding this plant in its Integrated Annual Report. However, information on its performance can be consulted at www.cnat.es. Materiality In terms of sustainability management and performance reporting, the EDP Group periodically identifies key themes and trends with the potential to impact the value creation for the company in the short, medium and long term. The material issues encompass both financial and non-financial dimensions, namely those of the economic, environmental and social dimensions that may influence, or be influenced by, different EDP stakeholders. The materiality analysis assesses and prioritises the relevance of an issue for EDP and its stakeholders. This analysis involves periodic reviews of stakeholders expectations, providing insights to support the organisation's decision-making and strategy development processes. For a comprehensive understanding of the EDP group's internal methodology in determining Materiality, along with a detailed list of topics, refer to the EDP group's Materiality Process Report at www.edp.com. Verification according to AA1000 (2018) Material topics 2.2 Materiality) are identified within the framework defined by AA1000 AP (2018), ensuring the identification of critical stakeholders; integrating their expectations into the corporate and operational strategy and seeking to respond appropriately to their expectations. As in previous years, EDP was subject to verification of compliance with AA1000 AP (2018) in 2023 by the auditors, PwC, specifically in the principles of inclusion, materiality, response and impact. Inclusion of stakeholders The principle of inclusion envisages that stakeholders are consulted, that their expectations and concerns are known and are incorporated into the decision-making process. Periodically, interaction initiatives are promoted with different segments of the company's stakeholders, while there are also dedicated communication channels devoted to specific segments. Response and Integrity EDP undertook commitments and delineated Action plans for material themes, replying strategically to the main stakeholders' expectations. The Objectives and Goals are listed in 2.4. Strategic priorities, and in 2.2. Materiality is the group's materiality matrix for 2023, whose themes are developed throughout the document. Internal and external assurance The overall coordination of the process of preparing the EDP Sustainability Report is the responsibility of the Sustainability Department. The contents are subsequently viewed and approved by the Executive Board of Directors. The external verification of sustainability content, carried out by PricewaterhouseCoopers & Associados - Sociedade de Revisores Oficiais de Contas, Lda. has the external verification level "Limited" for a set of indicators according to the GRI Table.

525 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency Annex 5. Tax transparency Tax mission and strategy The EDP Group believes it has both an ethical and civic obligation to contribute to the funding of essential government functions in the countries where the Group operates. As such, the Group manages its tax matters by adhering to the best tax practices, maintaining transparency, efficiency, and responsibility in tax payments, in strict accordance with the applicable legislation, while mitigating significant risks and avoiding needless disputes, and ensuring value creation for shareholders. The EDP Group's fiscal strategy is based on five main pillars: 1\. Compliance with Tax Laws and Regulations The Group conducts its fiscal responsibilities with diligence and professionalism, in alignment with the EDP Group Tax Mission, guided by the following principles: • implements the options which are most appropriate to the business and to the shareholders, in faithful compliance with the spirit and letter of the Law • pays the taxes that are due in all the countries where it carries out its activity • adopts the arm’s length principle, in the context of applicable international rules, guidelines and best practice on transfer pricing in the light of Organization for Economic Cooperation and Development (OECD) guidelines, and to this extent it has implemented an internal transfer pricing policy based on three main principles: • the terms and conditions of all EDP intra-group transactions are determined taking into consideration the inherent economic rational, the risks assumed and the functions performed by each party, in order to settle a price aligned with what is usually agreed between independent parties in comparable transactions • EDP fully complies with OECD Documentation Guidelines regarding intra-group transactions and takes into consideration the specific requirements of the internal legislation of each jurisdiction where the Group develops its activity • therefore, EDP transfer pricing Policy does not constitute an instrument for tax planning and / or tax evasion at EDP Group • adopts tax practices based on principles of economic relevance and commonly accepted business practices • discloses true and complete information concerning relevant transactions; and, • seeks to defend its legitimate interests by administrative means and, when appropriate, judicially, when the payment of any taxes, contributions and levies reasonably raises doubts regarding its legality. 2\. Ethical Tax Practices The EDP Group conducts all the tax affairs with integrity, responsibility, and a dedication to the highest ethical standards. Its approach involves a through and prudent interpretation of the prevailing tax laws governing its transactions, often with the support of legal experts and external advisors. When necessary and feasible, the Group seeks the opinion of local tax authorities to ensure that its actions are strictly aligned with the applicable legislation. This commitment to ethical tax practices not only ensures the Group full compliance with tax laws but also upholds its responsibility in contributing positively to the communities and societies in which the Group carries out its activity. 3\. Full collaboration with Tax Authorities The EDP Group is committed to maintain a relationship with the Tax Authorities of the countries where it operates based on principles of trust, good faith, transparency, cooperation and reciprocity, aiming to facilitate the application of the Law and to minimize litigation, despite the legitimate disputes that may arise with such authorities concerning the interpretation of applicable legal provisions. 4\. Risk Management The companies of the EDP Group shall adopt the control mechanisms necessary to ensure compliance with the tax laws and regulations, as well as the principles and good practices set forth in the EDP Group’s Tax Policy, as part of proper business management. The companies shall also use proper and sufficiently qualified human and material resources for such purposes, as well as technology to maximize the quality and accuracy of data to support tax management activities and the filing of related tax returns and forms. 

526 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency The tax risk management and control process begins with the identification and classification of the risks to which the EDP Group may be subject. In this sense, the EDP Group continuously assesses the tax risks and uncertainties, conducting regular exercises in order to identify, quantify and monitor risks that arise from external events with potential material impact. The EDP Group identifies the risks to which it is exposed based on the following classification: • compliance risk, associated with a potential failure to comply with tax obligations in a timely and complete manner • technical analysis risk, that may lead to potentially less appropriate tax decision- making, particularly in contexts where there is uncertainty in tax treatment • communication risk, associated with the possibility of an inadequate communication flow between internal tax teams and other corporate areas (e.g., business units) or external entities (e.g., Tax Authorities); and • reputational risk, related to the misinterpretation, by the stakeholders, of financial and tax information disclosed. In addition, the EDP Group has implemented a risk management policy with the goal of identifying, quantifying, managing, monitoring and mitigating, among others, the tax risks, namely the risk of materialization of the tax contingencies. EDP Group, through a specialized team, continuously monitors the processes associated with tax risks and contingencies (related and not related to ongoing litigation), in close cooperation with the respective Business Units, corporate legal services and external lawyers and advisors, with a bi-annual report of their evolution to the General and Supervisory Board of the EDP Group. Accountability for the tax Policy and its Supervision The EDP Group's Executive Board of Directors is involved in the decision-making process of the relevant operations, being its tax impact, if any, analysed and, documented as it may constitute an important element for the final decision, in order to ensure long-term value creation for shareholders. EDP also has a Financial Matters Committee/Audit Committee, whose main mission, upon delegation of the General and Supervisory Board, includes the permanent monitoring and supervision of any matters related to the internal control system over financial information and the risk management process, including its fiscal aspects. 5\. Transparency The EDP Group considers transparency a core principle of its fiscal function, particularly through: • Not using opaque structures or operating in jurisdictions lacking a substantial economic connection to its operations. The EDP Group does not establish subsidiaries in territories considered to be non-cooperating in accordance with Portuguese legislation and / or with the OECD standards; and, • Disclosure of tax information in accordance with the best international tax practices and accountability standards. This commitment aims to offer stakeholders a comprehensive view of the Group's contributions to the economies where it operates, emphasizing transparency and solidifying its position as a responsible and ethical participant in the global business community. • To this end, the EDP Group presents key tax information in both its financial statements and Sustainability chapter of its annual integrated report, guaranteeing clarity, usefulness, and accuracy in the information provided. In addition, it should be noted that the EDP Group, as a multinational group, fully complies with the annual communication and reporting obligations arising from the implementation of the provisions of Action 13 of the Base Erosion and Profit Shifting project (known as Country-by Country Reporting), which is part of a plan to strengthen transparency for tax administrations and that was adopted by the OECD and G20 countries. This obligation is fulfilled in Portugal by the parent company, in accordance with the established legal deadlines. Also, within the Framework of the OECD Pillar 2 - which aims to ensure a minimum overall effective taxation of 15% in each jurisdiction where the multinational groups have a presence - EU Directive 2022/2523 was published on 14 December 2022, which came into force the day following its publication in the Official Journal of the EU and should have been transposed by Member States by 31 December 2023. Taking into account the preliminary analysis carried out and EDP Group´s consolidated revenues, it is expected that the Group will be subject to this tax regulation. Portugal did not comply with the transposition deadlines, although it is expected that such transposition occurs during 2024. However, assuming that the transposition will strictly follow the Directive, no top-up tax is expected to be paid by EDP Group. 

527 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency In the countries where EDP Group carries out its activities and where the Pillar 2 rules were already enacted, we expect the safe harbours will apply and therefore no additional tax will be due. The fiscal footprint of EDP Group EDP Group is a utility present in 4 regional hubs, whose value chain includes the activities of generation, transmission and distribution and supply of energy. These activities trigger various types of taxes, levies and financial contributions which, when considered as a whole, determine the level of taxation to which the EDP Group is subject. Of all the stages in the EDP’s value chain, its energy generation activity is the one that contributes most significantly to the payment of taxes and other contributions. 

528 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency Global contribution of the EDP group In 2023, EDP Group’s global tax contribution to the public revenues of the countries where it is present amounted to approximately 2.9 billion euros, of which 0.9 billion euros correspond to own taxes and contributions borne (paid) by the EDP Group and circa 2 billion euros of taxes collected (contributions to the States on behalf of other economic agents), as shown in the following charts. Taxes borne (paid) by the EDP group, by the geographical area Taxes borne (paid) by the EDP group, by the type of contribution Taxes collected by the EDP Group and delivered to the states (burden of Other agents), by geographical area Taxes collected by the EDP group and delivered to the states (burden of Other agents), by type of contribution 51% 28% 19% 2% Portugal Brazil Spain Others €2 billion in 2023 34% 4% 38% 17% 7% Consumption Tax Social Security Contributions Payable by Workers Withholding tax (third-party income) Energy taxes Other €2 billion in 2023 28% 24% 19% 9% 6% 5% 4% 5% Spain Brazil Portugal Italy United States Poland Romania Other €0.9 billion in 2023 41% 22% 17% 9% 9% 2% Corporate income tax Energy taxes Social Security contributions Property tax Non-deductible VAT and similar Other taxes €0.9 billion in 2023 

529 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency Regarding the taxes borne by EDP Group, Spain is the country with the highest tax contribution in 2023, accounting for 28% of total taxes borne by EDP Group. On the other hand, considering the taxes incurred by EDP Group, the most relevant amount (41%) concerns to corporate income tax, followed by specific taxation on the energy sector (including the windfall tax paid in Spain, Romania, Italy and Poland) (22%), and, finally, social security contributions borne by companies (17%). Regarding corporate income tax rates, the nominal tax rates in the main countries in which EDP Group operates range between 16% in Romania and 31.5% in Portugal, adding municipal and state surtaxes to the nominal rate in the case of companies located in Portugal. In Portugal, the taxes borne (paid) in 2023 amounted to 180 million euros, emphasizing the weight of corporate income taxes amounting to 74 million euros, as well as social security contributions borne by the companies amounting to 78 million euros. In Spain, the taxes borne (paid) in 2023 amounted to 258 million euros, where the specific taxation on the energy sector should has the highest weight amounting to 116 million euros, followed by corporate income taxes that amounted to 88 million euros. Taxes collected by EDP Group and delivered to the States where it carries out its activity (burden of other agents) amounted to circa 2 billion euros in 2023, mostly related to the collection of consumption taxes (e.g. VAT) and withholding taxes on income.

531 Part V Integrated Annual Report 2023 Annexes | Annex 5. Tax transparency Specific taxation for the energy sector in 2023 The specific taxation on the energy sector carries significant weight within the EDP Group. In 2023, the EDP Group incurred taxes of this nature amounting to 206 million euros, as shown in the following graph. Indeed, in the year 2023, several European countries maintained or enforced the so-called "windfall taxes", which originated from Council Regulation (EU) 2022/1854 of October 6, 2022, establishing emergency intervention measures at the European Union level to address high energy prices. These measures included, among others, the introduction of price cap mechanisms for market revenues obtained by electricity producers from, essentially, renewable energy, and a temporary solidarity contribution applicable exclusively to companies active in the crude oil, natural gas, coal and refining sectors. Although the rules contained in this Regulation are aimed to create standardized measures in the European Union in response to the energy prices rise, certain countries where the EDP group is present have introduced unilateral measures, giving rise to the payment of windfall taxes in Spain, Romania, Italy, and Poland. While EDP fully acknowledges that the existing emergency situation required for extraordinary measures, the Company also considers that (i) the principle of not taxing unrealized extra-profits should always prevail and (ii) the compatibility with existing, legitimately implemented, risk management strategies, needs to be ensured. These requirements are necessary to avoid harming producers that do not actually benefit from the current high electricity prices, due to having hedged, individually or at Group level, their revenues, against fluctuations in the wholesale electricity market. These financial hedges follow the Company’s established low risk strategy to secure long term revenues and to remove electricity prices volatility on the company’s earnings. For these reasons, EDP will pursue all legal actions at its disposal in order to challenge the legality of these measures. The introduction of this tax in Spain resulted in the payment of 48 million euros by the EDP Group in 2023, making this country bear the highest level of energy taxation, representing about 57% of the total amount paid by the entire EDP Group. At the same time, there was a very significant decrease in the value of energy taxes paid in Portugal and Romania. In the case of Portugal, the reduction in terms of taxes paid was mainly due to (i) the suspension of the mechanism to restore competitive balance between electricity producers operating on Portuguese territory and electricity producers operating in Spain (known as clawback), (ii) the postponement of the collection of the amount corresponding to the social tariff for 2023 (which will be collected at the beginning of 2024, as stated in ERSE Directive 1-2024 of January 9, 2024), and (iii) the decision not to pay the CESE, whose constitutionality is being legally challenged by the EDP Group. In the case of Romania, the amount of tax paid decreased by approximately 69 million euros, as from March 2023, because the requirements for the application of the windfall tax in that country were no longer met. 11% 56% 13% 13% 7% Portugal Spain Romania Italy Other €206 million in 2023

583 Part V Integrated Annual Report 2023 Annexes | Annex 9. Reports on the allocation and impact of green finance and sustainability-linked loans Annex 9. Reports on the allocation and impact of green finance and sustainability-linked loans Sustainable financing Alignment with the SDG Objectives KPIs 2023 Target 2026 Sustainable financing 58% 60% In the end of 2023, sustainable finance amounted to €18.5 billion: (1) €11.1 billion in green bonds; (2) €6.7 billion in sustainability-linked loans and (3) 0.7 billion in green loans. The green financing (green bonds and loans) represented 58% of the nominal debt. EDP has a target to have 60% of its funding from sustainable sources by 2026. Our Green Bonds and green loans and sustainability-linked loans have promoted a greater alignment of the company’s financial policy with our sustainability strategy, while increasing market awareness for this topic. EDP’s sustainable financing has contributed heavily towards UN Sustainable Development Goal SDG 7: affordable and clean energy and SDG 13: climate action. Alignment with sustainability strategy EDP’s prioritization of investment in renewable generation started in 2006, through the anticipation of major trends in the energy market and the support to the vision of a society capable of reducing CO2 emissions, by replacing thermal with renewable energy, decentralizing generation, promoting smart grids and energy storage, and encouraging the demand for renewable electricity. Recognizing the climate emergency, EDP was one of the front runners undertaking the United Nation’s challenge during the Climate Summit in New York in 2019. EDP is committed to reduce emissions and to align its business strategy with the aim to limit global temperature raise to 1.5°C. Ramping up that commitment, EDP incorporated, in its Updated Strategic Plan 2021-2025, the ambitious goals to be coal free by 2025 and carbon neutral by 2030, supported by a strong investment in the acceleration of renewables installed capacity, smart grids, and decarbonized services for our customers. In the updated Business Plan for 2023-2026, EDP continued to lead the decarbonization of the energy sector by further reinforcing its investments in renewables with a €25 Bn energy transition CAPEX plan and with annual gross additions of 4.5 GW to reach an ambitious target of 50GW renewable additions for 2021-2030, while continuing its fast adoption of innovative solutions. EDP reinforced its ambition even further to reach Net Zero by 2040 by including the Scope 3 emissions in its targets. With a new baseline year set for 2020, EDP aims to reach net-zero greenhouse emissions across the value chain by 2040, with ambitious mid-term targets by 2030. These targets have been approved by SBTi under the Net Zero Standard. These climate commitments were recorded in EDP’s Climate Transition Plan ( details here), which was approved by a majority of votes (99,73%) in the General Meeting of shareholders held in April 2023. The proceeds of green bonds, green loans, and sustainability-linked loans contribute substantially to the implementation of EDP’s Climate Transition Plan and to reach our objectives of becoming coal-free by 2025 and net zero by 2040.Bonds and green loans are aligned with the taxonomy. For more details on the CAPEX indicator aligned with the Taxonomy, please refer to EDP's 2023 Taxonomy Report (here). The scope of the Taxonomy report includes the assets of subsidiary companies where the Group exercises control as of 31 December 2023. It should be noted that the amount of green debt is not accounted for in the CAPEX indicator aligned with the Taxonomy, because the use of proceeds, according to EDP's Framework for green financing, is intended to be used exclusively to (re)finance, in part or in full, new or existing eligible assets of EDP Renováveis and not CAPEX. Thus, there is no double counting. 

584 Part V Integrated Annual Report 2023 Annexes | Annex 9. Reports on the allocation and impact of green finance and sustainability-linked loans Green bonds and loans As part of EDP's strategy and to promote greater alignment of its financial policy with its sustainability strategy, in October 2018, the group (through EDP Finance BV) issued its first green bond, amounting to €600 million (senior debt). Since then, and until the end of 2023, EDP has issued approximately €11.8 billion in green bonds: eleven senior debt issuances, two of which in US dollars, and six subordinated debt issuances (hybrid). At the end of 2023, €11.1 billion green bonds will remain outstanding, partially replacing a 2019 green emission with the most recent hybrid emission. Additionally, EDP signed its first green corporate loan in 2023, for a total of €0.7 billion (one billion Singapore dollars). In September 2023, EDP updated its 2022 Green Finance Framework to reflect the changed scope and the new decarbonisation strategy. It includes the green financing instruments (for example, green bonds or green loans) issued by EDP, EDP finance BV, EDP \- Servicios Financieros España, S.A.U and EDP Renováveis and its subsidiaries and project companies to finance or refinance wind (onshore and offshore) and solar (PV and CSP) eligible assets and projects. These assets and projects will be included in the portfolio at the current IFRS balance sheet value. Eligible Green Assets will also include acquisitions of companies and equity participations in entities substantially active in wind and solar activities. EDP’s green finance framework is aligned with the International Capital Market Association’s (ICMA) Green Bond Principles 2021, the Loan Market Association’s (LMA) Green Loan Principles 2023 (GLP), as administered by LMA, Asia Pacific Loan Association (APLMA) and Loan Syndications and Trading Association (LSTA). The eligible assets and projects financed and refinanced will contribute towards the climate change mitigation objective of the EU Taxonomy. The framework is supported by a second- party review (SPO) from Sustainalytics. This report is part of the commitment to report on an annual and portfolio basis to investors on how the funding was allocated. The data presented here is externally verified. The details about the several issuances and the information included in this report is also available at EDP’s website (under the fixed income section). The impact indicators are the following: 1. Installed capacity of renewable (MW); 2. Net production of renewable (MWh) and 3. CO2 avoided emissions (tCO2), which corresponds to emissions that would have occurred if the renewable energy generated had been Green Bonds Issued over the period 2018-2023 €11.8B EDP’s Green Finance Framework EDP published an updated Green Finance Framework in September2023 Green Finance Framework SPO Sustainalytics is the opinion that the Framework’s two eligible activities fully align with the applicable Technical Screening Criteria in the EU Taxonomy and align with the Do No Significant Harm Criteria (fully for two and partially for climate change adaptation and biodiversity). The Framework is compliant with the EU Taxonomy’s Minimum Safeguards. 

585 Part V Integrated Annual Report 2023 Annexes | Annex 9. Reports on the allocation and impact of green finance and sustainability-linked loans produced by thermopower plants. It is the sum of CO2 avoided in each geography where EDP operates. For each geography, the renewable production (wind and solar) is multiplied by the emission factor of the country's thermoelectric mix. Approximately €11.7 billion issued in green bonds and loans between 2018 and 2023 were fully allocated by 31 December 2023, with 4.0 billion euros being allocated to new projects wind and solar that came into operation between 2018 and 2023, 5.8 billion euros being allocated to existing projects and 1.9 billion to equity participations and acquisitions. It should be noted that the amount of green funding allocated to new projects corresponds to wind and solar farms that have begun operating at the year of the date of issuance of the respective green bonds. The green funding allocated corresponds to the net proceeds of the issuances, calculated by extracting the upfront fees paid to arrangers from the gross proceeds. All EDP green issuances are aligned with EDP’s sustainability strategy, as part of EDP’s Strategic Agenda and Business Plan 2023-2026, with the proceeds being used to support its objectives to increase renewable capacity (coal-free by 2025 and 100% by 2030), and to reduce our scope 1 and 2 specific emissions by 77% by 2026 and 95% by 2030, using 2020 as base year, approved by SBTi in 2023, under the Net Zero Standard. EDP has committed to achieving Net Zero by 2040, reducing, in absolute terms, its CO2 emissions by 90%, against 2020 base year, including Scopes 1, 2 and 3. The impact of the portfolio was 12.9 GW of renewable energy capacity, 26.7 TWh of annual renewable energy production and the avoidance of 15.1 MtCO2 of emissions. These impact metrics are consolidated at a portfolio level. It should be noted that, since 2022, following the publication of our 2022 Green Finance Framework, green proceeds can be allocated to acquisitions of companies and equity participations in entities substantially active in wind and solar, which do not have impact KPIs associated, namely installed capacity (MW), production (GWh) and GHG emissions avoided (tCO2). In terms of geographical split, 64% of the projects financed with green proceeds are in the United States (43%), Singapore (11%) and Spain (11%). A minority of projects is in the United Kingdom (5%), Portugal (5%), Poland (5%), Romania (5%), Brazil (5%), Italy (3%), France (3%), and Mexico (3%). With negligible weight are projects in the geographies of Chile, Greece, Belgium, Taiwan, China, Canada, Vietnam, and the Netherlands. The following paragraphs report relevant information for investors on the application of EDP group's green bonds and loans proceeds and on the environmental benefits resulting from them.

Management of the funds obtained The net balance of the funds obtained through the emission of green bonds follows a portfolio approach. The resources shall be used to (re-)finance eligible green projects (wind and solar). Eligible green assets will also include acquisitions of companies and equity participations in entities substantially active in wind and solar. Until the net balance of the finds obtained from green bonds emissions has been fully assigned, EDP will invest the unassigned funds to the portfolio of eligible projects, in treasury liquidity or in the repayment/purchasing of existing debt, according to its own criteria. Net proceeds are expected to be fully allocated within 24 months from the issue date. Report on the application of the funds obtained The report is made based on the following indicators: • portfolio value of eligible projects • net balance of unused resources • quantity and percentage of new projects and existing projects Report on the impacts of the funds obtained The report is made based on the following indicators: • Installed capacity (MW) • CO2 Emissions avoided (tCO2) • Generation of renewable energy (MWh) Note: The CO2 emissions avoided correspond to the emissions that would have occurred if the electricity generated by renewable sources had been produced by thermal power stations. For each country, this is obtained by multiplying the net renewable generation by the emission factor for thermally generated electricity in the country.

595 Part V Integrated Annual Report 2023 Annexes | Annex 9. Reports on the allocation and impact of green finance and sustainability-linked loans Sustainability – linked loans The year of 2022 was marked by EDP’s first sustainability-linked Revolving Credit Facility (RCF) of €3.7 billion (RCF 2022), aligned with the Sustainability-linked Loan Principles from the Loan Market Association. EDP is at the front of the energy transition with ambitious commitments to achieve 100% renewables generation by 2030, and to become coal free by 2025 and carbon neutral by 2030. The KPIs are presented below. They are included in EDP’s executive board of directors’ remuneration scheme. • KPI #1 (RCF 2022): Percentage reduction of total Scope 1 and 2 GHG emissions per TWh produced by the group compared 2015 levels. Targets are aligned with 2025 public commitment to reduce by 70% and 2030 target to reduce by 98% by 2030, under the Business Plan 2021-2025, approved by SBTi with a decarbonisation path of 1.5⁰C. Scope 1 and 2 GHG emissions reduced in 2023 by 49.7% compared to 2022, which corresponds a reduction of 78% against the 2015 emissions. Emissions intensity (scope 1+2) reduction (%), compared to 2015 (RCF 2022) In 2023, EDP refinanced its second sustainability-linked RCF of €3.0 billion (RCF 2023), in line with the principles of the Loan Market Association's sustainability-linked loans. The KPIs are identical to those of the RCF 2022. However, the targets have been updated in line with the updated business plan for 2023-2026 and public commitments. The base year for KPI #1 has been changed from 2015 to 2020. • KPI #1 (RCF 2023): Percentage reduction of total Scope 1 and 2 GHG emissions per TWh produced by the group compared 2020 levels. Targets are aligned with the Business Plan 2023-2026 and public commitments to reduce 77% by 2026 and reduce 95% by 2030 and approved by SBTi under the Net Zero Standard. GHG emissions reduced in 2023 by 49.7% compared to 2022, which corresponds a reduction of 49% against the 2020 emissions. Emissions intensity (scope 1+2) reduction (%), compared to 2020 (RCF 2023) -22.5 -4.6 -26.4 -36.4 -56.9 -51.2 -55.6 -77.7 2016 2017 2018 2019 2020 2021 2022 2023 12.3 2.0 -48.7 2021 2022 2023
