To determine whether IBERDROLA SA is suitable to issue hybrid bonds, we can analyze the provided financial data for the 2022 fiscal year across several critical dimensions:

1. **Size and Market Position**: IBERDROLA SA is a massive utility company, holding total assets of 154.67 billion EUR and generating revenues of 53.95 billion EUR. Companies of this scale in the utility sector generally enjoy highly stable, predictable cash flows and possess strong access to capital markets.

2. **Profitability and Cash Generation**: The company reported a robust EBITDA ("Beneficio Bruto De Explotacion Ebitda") of 13.23 billion EUR and strong positive Cash Flows from Operating Activities of 10.44 billion EUR. It also posted a strong net profit of 5.06 billion EUR. These figures indicate exceptionally healthy operational margins and the liquidity necessary to consistently cover fixed income and subordinated obligations.

3. **Leverage and Capital Structure**: The company has an equity base of 58.11 billion EUR. While it carries substantial financial debt (roughly 44.22 billion EUR in non-current and 25.08 billion EUR in current financial liabilities), this debt load is typical and manageable for a capital-intensive utility company. The strong equity base ensures that the issuance of hybrid debt would receive favorable equity credit from rating agencies without over-leveraging the balance sheet. 

4. **Precedent Transactions**: The financial statements explicitly report the prior issuance of hybrid capital, seen under "Emision De Obligaciones Perpetuas Subordinadas" (Issuance of subordinated perpetual bonds) totaling 2.74 billion EUR in the previous year, as well as the ongoing accrual and payment of interest for these instruments. This proves the company already actively and successfully utilizes hybrid bonds in its capital structure.

Given its massive scale, steady and highly reliable cash flow generation, strong profitability, and established history of issuing perpetual subordinated debt, the company represents a prime candidate for hybrid bond issuance.
