To assess the suitability of Acciona S.A. for the issuance of hybrid bonds, we evaluate the company's business profile and financial position based on the provided 2022 annual report data and the provided methodology.

**Business Profile:**
Acciona is a conglomerate focused on sustainable infrastructure, renewable energy, and water services. These sectors (particularly regulated utilities, renewables, and infrastructure) typically exhibit the long-term, stable, and visible cash flows characteristic of "infrastructure-like" businesses. The company’s focus on energy transition and essential services aligns with the "Strongly Suitable" profile for hybrid capital, as these sectors are capital-intensive and often require a mix of equity-like and debt-like financing to maintain credit ratings while funding significant growth.

**Financial Position:**
*   **Revenue and Profitability:** Acciona has shown strong growth, with revenue increasing significantly (from 8.1B EUR in 2021 to 11.2B EUR in 2022) and operating profit (EBIT) rising from 829M EUR to 1.33B EUR.
*   **Leverage and Debt:** While the company has substantial non-current financial liabilities and debt (total non-current liabilities increased from 7.1B EUR to 8.5B EUR), it also maintains a strong equity base (6.3B EUR in 2023). 
*   **Rationale:** As an infrastructure and renewable energy company, Acciona faces large, long-term capital expenditure requirements. Hybrid bonds are a well-recognized instrument in this sector to optimize the capital structure, provide rating headroom, and support large project pipelines without fully diluting existing shareholders. The company's scale and importance in the energy sector support its ability to access institutional capital markets for complex instruments like hybrids.

**Assessment:**
Acciona fits the criteria for "Strongly Suitable" because it operates in essential infrastructure/energy sectors with visible, long-term cash flows, and it is a capital-intensive business where hybrid issuance can materially provide the necessary rating headroom to pursue its investment strategy while maintaining a robust investment-grade credit profile. The capital intensity inherent in its business model (renewables and infrastructure) makes hybrid instruments a strategic tool for balancing growth and financial leverage.
