Bouygues appears **Marginally Suitable** for hybrid bond issuance.

Key considerations:

- **Business profile:** Bouygues is a large, diversified French group with activities in construction, telecoms, media, and infrastructure-related services. It is not a regulated utility or classic infrastructure issuer, but parts of its business are infrastructure-adjacent and telecom exposure provides some recurring cash-flow visibility. However, construction and contracting activities introduce cyclicality, execution risk, working-capital volatility, and margin pressure.

- **Scale and market access:** The group is very large, with 2022 revenue of about **€44.3bn**, total assets of **€60.6bn**, and equity of **€13.9bn**. This scale, its listed status, and established capital-market access support the feasibility of issuing hybrids.

- **Leverage and credit rationale:** Net debt increased sharply from **€0.9bn** to **€7.4bn**, largely reflecting acquisition activity and financing needs. S&P Net Debt / EBITDA was **3.26x**, and S&P FFO / Net Debt was **24.46%**, suggesting a BBB-type financial profile with reduced headroom. Moody’s adjusted leverage trend is described as **deteriorating**, which strengthens the rationale for hybrid capital as a way to support credit metrics and preserve rating flexibility.

- **Use-of-proceeds rationale:** The company had major investing cash outflows in 2022, including **€6.3bn** used to obtain control of subsidiaries, and financing inflows of **€5.7bn** from borrowings. This provides a credible M&A/refinancing/deleveraging rationale for hybrid issuance.

- **Cash flow and coverage:** Operating cash flow remained positive at about **€3.0bn**, but free cash flow after capex was much tighter, and dividends continued. Interest expense also rose. A hybrid could provide useful rating-equity credit, but it would also be relatively expensive subordinated capital, especially given the 2022 rise in rates and credit spreads.

- **Hybrid issuance precedent:** Bouygues had **not issued hybrid bonds in 2021 or 2022** and has **never issued hybrids**. This is a significant negative signal under the provided guidance and suggests hybrids are not a core recurring funding tool for the company. It prevents a “Strongly Suitable” assessment despite the potential rating benefit.

Overall, Bouygues has sufficient size, market access, leverage pressure, and M&A/refinancing rationale to make hybrid issuance plausible. However, its mixed industrial/infrastructure profile, lack of prior hybrid issuance, and sensitivity to market pricing make it more **opportunistic than structurally natural** as a hybrid issuer.
