**Business profile and cash‑flow visibility**  
ENGIE operates a mix of regulated electricity‑ and gas‑distribution networks (which benefit from transparent, predictable tariff‑setting and cost‑recovery mechanisms) and large‑scale renewable‑ and conventional‑power‑generation assets. The regulated activities provide highly visible, contract‑type cash flows, while the generation portfolio – although exposed to merchant risk – is diversified across fuels, geographies and contract structures. This combination is characteristic of an “energy‑infrastructure” issuer that the guidelines treat as strongly suitable for hybrid issuance.

**Credit rating and leverage**  
ENGIE carries an investment‑grade rating in the BBB area (typically BBB+ from S&P). Its balance‑sheet metrics are moderate:  
- Net debt ≈ €25 bn (total borrowings ≈ €40.6 bn less cash ≈ €15.6 bn)  
- EBITDA ≈ €9.5 bn (operating income ≈ €4.3 bn plus D&A ≈ €5.2 bn) → Net‑debt/EBITDA ≈ 2.6×  
- Funds from operations (CFO + interest paid) ≈ €9.4 bn → FFO / total debt ≈ 23 %  

These ratios sit comfortably within the BBB‑category tolerances, but the 2022 profit decline (net profit ≈ €0.4 bn vs. €3.8 bn in 2021) signals pressure on earnings. A hybrid instrument would be counted as equity by rating agencies, providing an immediate boost to equity‑credit‑adjusted leverage and preserving rating headroom.

**Hybrid‑bond rationale**  
ENGIE already has “Deeply Subordinated Perpetual Notes” (≈ €3.4 bn at end‑2023) classified in equity, representing existing hybrid debt. The notes are being gradually repurchased, suggesting upcoming refinancing needs. Issuing new hybrid bonds would:  
1. Refinance the maturing hybrid layer, extending the maturity profile and avoiding a lump‑sum repayment.  
2. Improve adjusted leverage (FFO/debt, net‑debt/EBITDA) because hybrids receive 50 % equity credit in S&P’s capital structure.  
3. Provide a cost‑efficient alternative to equity issuance, especially in a rising‑rate environment where hybrid spreads remain attractive for investment‑grade issuers.  

Thus, the hybrid issuance is not opportunistic; it is a core element of ENGIE’s liability‑management strategy.

**Conclusion**  
ENGIE’s regulated‑utility backbone, investment‑grade rating, moderate leverage, strong cash‑flow generation and clear refinancing/liability‑management rationale satisfy the “Strongly Suitable” criteria for hybrid‑bond issuance.
