EDF is **highly suitable in principle** for hybrid bond issuance, despite very weak 2022 financial performance.

Key reasons:

- **Issuer type is very supportive:** EDF is a major French electricity utility with regulated and quasi-regulated infrastructure characteristics, large essential-service operations, and significant state/public-policy importance. This fits the typical hybrid issuer profile well.

- **Clear precedent and market credibility:** EDF has already issued hybrid/perpetual subordinated bonds, with first issuance in **2013** and further issuance in **2021/2022**. Existing and repeated hybrid issuance is a strong signal that the structure is accepted by investors and rating agencies for this issuer.

- **Strong rationale for hybrid capital:** 2022 was a severe stress year:
  - EBITDA/EBE turned negative: **-€5.0bn** versus **€18.0bn** in 2021.
  - Net loss was **-€18.2bn** versus profit of **€4.8bn** in 2021.
  - Operating cash flow was **-€7.4bn** versus **+€12.6bn** in 2021.
  - Capex/investment cash outflow remained very large at **€25.1bn**.
  - Financial debt/liability balances increased materially.
  - Moody’s adjusted leverage trend is explicitly **deteriorating**.
  These conditions create a strong balance-sheet and rating-headroom rationale for hybrid issuance.

- **Hybrid improves credit metrics and preserves rating headroom:** EDF’s reported S&P metrics are deeply stressed, including **S&P Net Debt / EBITDA of -8.22** and **FFO / Net Debt of -15.8%**. While negative EBITDA and FFO limit near-term metric usefulness, hybrid equity credit can still support adjusted leverage, capitalization, and rating stability versus issuing only senior debt.

- **Large ongoing funding needs:** EDF has heavy capital expenditure requirements, nuclear-related obligations, regulated network investment, and refinancing needs. Hybrid bonds are a relevant tool to fund long-duration infrastructure investment while limiting pressure on adjusted debt metrics.

- **Financial policy credibility:** Payments to perpetual subordinated bondholders continued, and EDF accessed equity and debt markets in 2022, including proceeds from borrowings and subordinated liabilities. The company’s scale, strategic importance, and past hybrid track record support institutional market access.

- **Market conditions were less favorable in 2022:** Rates and credit spreads rose materially versus 2020–2021, making hybrids more expensive. However, for EDF, the credit-supportive rationale likely outweighs the higher coupon cost.

The main weakness is that 2022 results were extremely poor, with negative earnings and operating cash flow. For an ordinary corporate issuer this could make hybrid issuance questionable. However, EDF is not a typical cyclical or speculative issuer: it is a strategic regulated/quasi-regulated utility with demonstrated hybrid market access, recurring capital needs, and a strong need to protect credit quality.

Therefore, the most appropriate assessment is:
