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

Bouygues is a large, diversified French group with significant scale: 2022 revenue was **€44.3bn**, recurring operating profit **€2.0bn**, and total equity **€13.9bn**. It has credible access to institutional capital markets and is likely perceived as an investment-grade-style issuer, supported by its size, diversification, long operating history, and public-market profile.

However, it is **not a pure regulated utility or infrastructure issuer**. The group’s business mix is largely construction, telecoms, media, and related industrial/services activities. Some segments may have infrastructure-like or recurring characteristics, but the overall group has meaningful exposure to competitive and cyclical end markets, project execution risk, working capital swings, and M&A integration risk. Therefore, its cash-flow visibility is weaker than that of a regulated utility, transport infrastructure concession, or regulated energy network.

The main argument in favor of hybrid issuance is the sharp deterioration in leverage following major acquisition activity. Net debt increased from **€0.9bn at year-end 2021 to €7.4bn at year-end 2022**, while long-term borrowings roughly doubled to **€11.6bn**. Investing cash flow was heavily negative at **€8.6bn**, including **€6.3bn** used to obtain control of subsidiaries. This gives a clear M&A/deleveraging rationale: a hybrid could help protect rating headroom by receiving partial equity credit from rating agencies and improving adjusted leverage metrics versus issuing only senior debt.

That said, operating cash generation remains positive but not exceptionally strong relative to the enlarged debt load. Operating cash flow was **€3.0bn**, down from **€3.6bn**, while capex on PPE and intangibles was **€2.6bn**, leaving limited free cash flow before dividends. Dividends to parent shareholders were **€680m**, and total dividends **€777m**, further reducing deleveraging capacity. Interest expense rose, and the 2022 rate environment was materially less favorable than prior years, increasing the cost of hybrid capital. A hybrid would likely be useful as temporary credit support rather than a core recurring funding instrument.

Overall, Bouygues has sufficient scale, market access, and a clear M&A/leverage-management rationale for hybrid issuance, but its industrial and partially cyclical profile prevents a “Strongly Suitable” assessment. It is better characterized as an opportunistic or rating-headroom-driven hybrid candidate.
