Iberdrola S.A. appears **Strongly Suitable** for hybrid bond issuance.

Key reasons:

- **Highly suitable sector profile:** Iberdrola is a large integrated utility with substantial regulated and quasi-regulated electricity network, generation, and infrastructure-like activities. This gives it relatively visible cash flows compared with cyclical industrial or commodity issuers.
- **Large scale and diversification:** Total assets were about **€154.7bn** at year-end 2022, with property, plant and equipment of **€86.3bn**. Revenue increased to **€53.9bn**, EBITDA was **€13.2bn**, and operating cash flow was **€10.4bn**. The group has significant geographic and business diversification, which supports market access.
- **Investment-grade-style credit metrics but leverage relevant:** S&P net debt / EBITDA was **3.91x** and S&P FFO / net debt was **19.65%**. These are consistent with a capital-intensive BBB-area utility profile where hybrids can provide meaningful rating-agency equity credit and support leverage metrics.
- **Clear funding rationale:** Iberdrola has a very large capex program, with 2022 investing cash outflow of about **€10.2bn**, including **€6.3bn** of PP&E purchases. Hybrid capital is well suited to funding long-dated regulated/renewable infrastructure investment while preserving credit metrics.
- **Established hybrid issuer:** The company first issued hybrids in **2013** and issued hybrid bonds in **2021 or 2022**. This is a strong positive signal: hybrids are already part of its accepted capital structure and investor base.
- **Financial policy credibility:** The group has demonstrated ongoing access to debt and hybrid capital markets. It raised substantial conventional debt in 2022 and maintained sizable liquidity, including **€4.6bn** of cash and equivalents.
- **Rating-headroom benefit:** Even though Moody’s adjusted leverage trend is described as stable, the capital-intensive growth plan and elevated leverage mean hybrid issuance can still be an important recurring instrument to preserve rating headroom and avoid excessive senior debt issuance.
- **Market conditions:** 2022 rates and credit spreads were meaningfully higher than in 2020-2021, making hybrids more expensive, but for a large utility incumbent with a proven hybrid track record, investor appetite should remain comparatively strong.

Overall, Iberdrola fits the archetype of a strong hybrid issuer: large, investment-grade, regulated/utility-like, capital-intensive, with recurring funding needs and an established history of hybrid issuance.
