To assess whether Iberdrola, S.A. is suitable to issue hybrid bonds, we analyze its financial position and capital structure based on the provided data for the fiscal year ending 2022:

1.  **Profitability and Earnings Stability:** Iberdrola demonstrates strong, growing profitability with Revenue rising from 39.1 billion EUR in 2021 to 53.9 billion EUR in 2022. Operating profit grew from 7.3 billion EUR to 7.9 billion EUR, and net profit attributable to the parent reached 4.3 billion EUR. This consistent performance provides the necessary recurring cash flow to service interest payments on hybrid instruments.
2.  **Existing Capital Structure:** The company already utilizes hybrid-like instruments, as evidenced by the line items "Instrumentos De Capital Con Caracteristicas De Pasivo Financiero No Corriente" (576 million EUR) and "Emision De Obligaciones Perpetuas Subordinadas" (previous issuance of 2.7 billion EUR in 2021). The presence of these instruments in the balance sheet confirms that the company is familiar with this type of financing and considers it a viable part of its capital management strategy.
3.  **Financial Health:** With 154.6 billion EUR in assets and 58.1 billion EUR in total equity, the company maintains a solid capital base. Its ability to generate significant operating cash flows (10.4 billion EUR in 2022) indicates a strong capacity to meet the coupon obligations associated with hybrid debt.
4.  **Strategic Use of Capital:** The company is actively investing heavily in "Property Plant And Equipment" (86.3 billion EUR) and "Construction In Progress" (11.5 billion EUR). Issuing hybrid bonds is a standard practice for utility companies to fund long-term infrastructure projects while maintaining a favorable credit profile by receiving partial equity treatment from rating agencies.

Given the existing track record of issuing subordinated perpetual obligations and the stable, high-scale nature of its utility business, the company is in an excellent position to issue further hybrid bonds to optimize its capital structure.
