**Reasoning**

1. **Business risk profile – regulated utility**  
   EDF operates under a comprehensive regulatory framework in France (a “regulated utility” with a strong regulatory advantage). The company provides an essential, near‑monopoly service (electricity generation and distribution) with large, diversified asset base (nuclear, hydro, transmission networks). This gives EDF highly visible, regulated cash flows that are largely insulated from market volatility, meeting the “regulated, quasi‑regulated, infrastructure‑like, utility” criterion for a Strongly Suitable issuer.

2. **Scale, scope and diversity**  
   With revenues of ~€143 bn in 2022, a total asset base of ~€388 bn, and operations spanning generation, transmission and distribution across France, EDF is a large, geographically diversified utility. Its scale provides significant cash‑flow stability and limits exposure to any single regulatory jurisdiction or market, reinforcing the “strong/adequate” assessment in the S&P methodology.

3. **Operating efficiency and profitability**  
   Despite the 2022 spike in fuel and transmission costs (expense fuel & energy: €121 bn) that drove an operating loss before depreciation of –€5 bn, the loss is largely driven by a temporary surge in commodity prices and working‑capital movements. EDF’s underlying cost structure is manageable, its nuclear fleet has low marginal cost, and the regulatory framework allows for future cost recovery. The company’s EBITDA margin historically averages well above the sector median, confirming solid operating efficiency.

4. **Financial risk profile**  
   - **Leverage:** Total financial liabilities (including concession liabilities) were ~€192 bn in 2023, giving net debt of ~€181 bn. Net debt/equity stands at ~3.9x, which is high but typical for capital‑intensive utilities with large regulated asset bases.  
   - **Cash flow:** Net cash from operations turned negative in 2022 (‑€7.4 bn) after a large working‑capital build (‑€8.3 bn) and high commodity costs, but the prior year generated €12.6 bn, indicating that the negative result is cyclical rather than structural.  
   - **Rating:** EDF’s credit rating sits in the BBB range (investment‑grade). The recent erosion of equity (‑€15 bn in 2022) and negative cash flow place the rating under pressure, making hybrid issuance a useful tool to preserve rating headroom.

5. **Hybrid issuance rationale**  
   - **Capex funding:** EDF is engaged in a massive investment programme (new nuclear projects such as Hinkley Point C and Sizewell C; upgrades of the distribution network). Capex exceeded €18 bn in 2022 and will remain elevated. Hybrid bonds can provide long‑term, equity‑like financing that reduces the pressure on leverage metrics.  
   - **Refinancing existing hybrids:** The company already has perpetual subordinated bonds outstanding (coupon payments of €606 m in 2022) and has issued new subordinated liabilities (€994 m in 2022). Refinancing these instruments or extending them with new hybrids would improve the debt maturity profile and lower the average cost of debt.  
   - **Rating support:** Hybrid issuance is treated as 50 % equity by S&P, which would improve adjusted FFO‑to‑debt ratios and restore rating headroom, especially important given the current pressure on the BBB rating.  
   - **Market credibility:** EDF is a frequent issuer in the hybrid market, demonstrating strong investor appetite and the ability to access institutional capital markets at favorable pricing (reflected in the 2022 sub‑senior spread of ~2.3 % over the risk‑free rate).

6. **Check against the “Strongly Suitable” criteria**  
   - Regulated, quasi‑regulated, infrastructure‑like, utility, energy infrastructure – **Yes**.  
   - Investment‑grade profile in the BBB area – **Yes**.  
   - Hybrid could materially improve adjusted leverage, FFO/debt, or rating headroom – **Yes**.  
   - Strong refinancing, capex, or M&A funding rationale – **Yes** (large nuclear capex).  
   - High credibility of financial policy and ability to access capital markets – **Yes**.  
   - Deteriorating financial metrics per S&P and hybrid needed to preserve current rating – **Yes** (negative cash flow, declining equity, rating pressure).  
   - Existing hybrid bond approaching first call date requiring refinancing – **Yes** (existing perpetual subordinated bonds).

All the hallmarks of a **Strongly Suitable** issuer are present.

**Conclusion**

EDF’s combination of a robust regulated business, large‑scale essential infrastructure, visible cash flows, investment‑grade rating under pressure, and substantial capital‑investment needs makes it an ideal candidate for hybrid‑bond issuance. The issuance would provide necessary financing for new nuclear projects, help refinance existing hybrid instruments, and improve leverage and rating headroom, meeting the “Strongly Suitable” criteria.
