**Reasoning**

Bouygues is a French conglomerate with construction, real‑estate, telecom (Bouygues Telecom – a challenger to the incumbent Orange) and media activities. Its business profile is therefore **industrial / partially regulated / telecom‑challenger / real‑estate**, i.e. the “marginally suitable” category in the guidelines.

Financially, the group shows:
- Net debt of €7.4 bn and a S&P‑adjusted Net‑Debt/EBITDA of **3.26** (moderate‑high leverage).  
- FFO/Net‑Debt of **0.24**, indicating a relatively low cash‑flow coverage of debt.  
- Moody's notes an **deteriorating** adjusted‑leverage trend.

These metrics are not at distress levels, but they are not comfortably investment‑grade‑strong either. A hybrid issuance could improve the leverage and coverage ratios, providing a modest rating headroom, but the benefit would be **incremental rather than material**.  

Moreover, Bouygues has **never issued a hybrid bond** and has no hybrid bond approaching a call date. The absence of a recent (or any) hybrid‑bond programme is a strong signal that the company is not a natural issuer of hybrid capital; the instrument would be **opportunistic** rather than a core funding tool.

All the above points align with the “Marginally Suitable” profile: the issuer is not highly regulated nor infrastructure‑like, the hybrid would be used for opportunistic financing (de‑leveraging, M&A, refinancing), and the rating benefit would be moderate. The company does not meet the “strongly suitable” criteria (no material rating‑preserving need, no existing hybrid to refinance, not a regulated utility or telecom incumbent) nor the “not suitable” criteria (it is not highly cyclical, distressed, or sub‑investment‑grade).

**Conclusion**

The entity is **Marginally Suitable** for a hybrid‑bond issuance.
