2. **Financial Strength:** The company has a solid equity base of 4.467 billion EUR as of the end of 2022. Its ability to generate substantial cash from operating activities (1.26 billion EUR) demonstrates operational health.
3. **Capital Structure:** A2A S.p.A. maintains a diverse capital structure, including issued capital, reserves, and non-controlling interests. It has access to financial markets, evidenced by its significant borrowing activities and repayment history.
4. **Business Profile:** As a major utility company (with ownership by the Municipalities of Milan and Brescia), it provides essential services, which typically implies stable, long-term cash flows that are attractive for hybrid bondholders who look for credit stability.
5. **Hybrid Suitability:** Hybrid bonds (often treated as equity for accounting/rating purposes under certain conditions) are well-suited for capital-intensive utility companies looking to optimize their balance sheet while maintaining or improving their credit metrics. Given A2A's stable operational history, size, and consistent profitability, it possesses the characteristics typically required by issuers of hybrid debt.
