To assess suitability for issuing hybrid bonds, I’ll examine key credit metrics implied by the data:  
- **Leverage**: Total equity (including non-controlling interests) at end-2022 is €58.1 bn vs. total assets €154.7 bn. Net financial debt (gross financial liabilities minus cash) is substantial.  
- **Profitability & coverage**: EBITDA of €13.2 bn provides strong coverage of interest costs (finance costs €3.0 bn), giving an EBITDA interest cover over 4x.  
- **Cash flow**: Operating cash flow is robust at €10.4 bn, comfortably exceeding investing outflows (€10.2 bn) and providing room for dividends and debt service.  
- **Capital intensity**: High capex (€6.3 bn in PP&E alone) suggests ongoing need for flexible funding, suited to hybrid instruments.  
- **Equity base**: Solid equity cushion reduces risk for subordinated instruments.  
- **Hybrid precedent**: The company already has perpetual subordinated obligations, indicating market acceptance.

Given strong cash generation, manageable leverage, and precedent, Iberdrola S.A. appears well-positioned for hybrid bond issuance.
