To assess whether Bouygues SA is suitable to issue hybrid bonds, we evaluate its financial profile based on the provided 2022 annual report data:

1.  **Earnings Stability and Profitability:** The company demonstrates consistent profitability, with a "Profit/Loss from Operating Activities" of 1.872 billion EUR in 2022 and 1.733 billion EUR in 2021. It has generated positive cash flows from operations in both years (2.978 billion EUR in 2022; 3.576 billion EUR in 2021), indicating a stable ability to service interest payments.
2.  **Financial Position and Leverage:** While the company has seen an increase in its long-term borrowings (from 5.805 billion EUR in 2022 to 11.586 billion EUR in 2023) and Net Debt (from 941 million EUR in 2022 to 7.44 billion EUR in 2023), the company maintains a substantial equity base (13.932 billion EUR in 2023). The significant rise in goodwill and noncurrent assets suggests an expansionary phase, which often precedes capital structure optimization via hybrid debt.
3.  **Nature of Business:** As a large-scale, established "Société anonyme" with diverse revenue streams (44.322 billion EUR in 2022), Bouygues has the size and operational scale typically associated with issuers of corporate hybrid securities (which are used to manage leverage ratios while maintaining or improving credit ratings).
4.  **Credit Capacity:** The company is currently profitable and holds significant assets, making it a viable candidate for hybrid instruments, which are often used by such entities to finance large acquisitions (evidenced by the 6.269 billion EUR cash flow used in obtaining control of subsidiaries in 2022) or to manage long-term capital structure.

Given the stable profitability, strong asset base, and the recurring need for long-term financing to support its scale, the company presents a profile that is well-suited for the issuance of hybrid bonds.
