To assess Iberdrola’s suitability for issuing hybrid bonds, we look at several key credit and equity factors.

**Profitability and Coverage**  
- Revenue for 2022 was €53,949 million, up from €39,114 million in 2021.  
- EBITDA rose to €13,228 million from €12,006 million.  
- Profit from operating activities increased to €7,984 million.  
- Finance costs were €3,042 million, giving strong interest coverage (EBITDA/Finance Costs ≈ 4.35x).

**Capital Structure and Leverage**  
- Total equity is €58,114 million, with €41,119 million attributable to the parent.  
- Non-current financial liabilities are €44,216 million, and current financial liabilities are €25,079 million.  
- The equity base, plus existing perpetual obligations treated as equity (shown in reserves movements), supports additional subordination layers.

**Cash Flow Strength**  
- Cash flow from operating activities is €10,443 million, well exceeding investment needs (investing cash outflows of €10,154 million were largely capex).  
- Free cash flow after dividends and interest is positive enough to service hybrid coupons.

**Regulatory and Business Profile**  
- Iberdrola is a large, regulated utility with stable cash flows, making it a typical issuer of hybrids for rating agency equity credit.

**Existing Hybrid Issuances**  
- The data shows movements in perpetual subordinated obligations (“Emision de Obligaciones Perpetuas Subordinadas” and related interest), meaning the company already has hybrid-like instruments and experience in this market.

Given the robust coverage, solid cash flow, large equity base, and positive market/regulatory profile, the company is clearly suitable.
