**Reasoning**

ENGIE is a large, diversified energy‑utility group with a mix of regulated network businesses and power‑generation activities. Its credit profile is investment‑grade (BBB range) and the key S&P leverage metrics for 2022 (Net Debt/EBITDA ≈ 3.25× and FFO/Net Debt ≈ 24.8 %) are in line with typical utility ratios. Moody's notes an improving leverage trend, indicating that the company’s credit quality is stable rather than deteriorating.

Key factors supporting a “Strongly Suitable” rating for hybrid‑bond issuance:

1. **Business profile** – The company operates essential, infrastructure‑type assets (electricity and gas networks, renewables) with highly visible, regulated cash flows, which meets the “regulated, quasi‑regulated, infrastructure‑like, utility” criterion for strong suitability.

2. **Investment‑grade status** – ENGIE sits in the BBB area, a typical sweet‑spot for hybrid issuance that can be treated as equity‑like capital while retaining a solid rating.

3. **Existing hybrid‑bond program** – ENGIE has already issued hybrid bonds (first issuance in 2014) and continued issuance in 2021‑2022, demonstrating market acceptance and an established framework for such instruments.

4. **Funding rationale** – The group has material capex needs (energy transition, renewable build‑out) and a large, well‑balanced debt maturity profile. Hybrid issuance would provide cost‑effective financing, improve adjusted leverage (Net Debt/EBITDA) and increase rating headroom, matching the “Strong refinancing, capex, or M&A funding rationale” condition.

5. **Cash‑flow generation** – Operating cash flow for 2022 was €8.6 bn, well above the level needed to service hybrid coupons and to maintain financial flexibility.

6. **Market context** – The euro‑denominated hybrid‑bond market (iBoxx EUR Non‑Fin IG sub‑senior delta ≈ 0.2) offers attractive pricing for investment‑grade issuers, and ENGIE’s credit metrics support access to that market.

No major counter‑indications exist: the company is not in a highly cyclical commodity pure‑play, nor is it distressed; its metrics are not deteriorating, and the hybrid issuance would not be perceived merely as expensive sub‑ordinated debt.

**Conclusion**

ENGIE meets the criteria for a strongly suitable candidate for hybrid‑bond issuance: it has an investment‑grade BBB profile, a long‑standing hybrid‑bond program, visible regulated cash flows, clear funding needs, and the financial flexibility to use hybrid capital effectively. Therefore, the entity is **Strongly Suitable** to issue hybrid bonds.
