To assess the suitability of Veolia Environnement for issuing hybrid bonds based on the provided 2022 annual report data, we consider several key financial metrics:

1.  **Capital Structure & Hybrid Track Record:** The company already maintains a significant volume of "Titres Super Subordonnes ADuree Indeterminee" (Deeply Subordinated Securities), which grew from 2,460,700,000 EUR (2022-01-01) to 3,496,300,000 EUR (2023-01-01). This confirms the company has an established framework and successfully utilizes hybrid instruments as part of its capital management strategy.
2.  **Profitability:** The company demonstrates positive and growing profitability, with "Profit Loss" increasing from 554,900,000 EUR in the 2021-2022 period to 997,600,000 EUR in the 2022-2023 period. "Profit Loss Attributable To Owners Of Parent" also showed a strong increase from 404,300,000 EUR to 715,800,000 EUR.
3.  **Operating Cash Flow:** There is a robust generation of operating cash flow, with "Cash Flows From Used In Operating Activities" rising from 3,147,200,000 EUR to 4,148,200,000 EUR, providing a solid cushion to cover the coupon payments associated with hybrid debt.
4.  **Equity Strength:** Total equity increased from 12,770,000,000 EUR to 14,866,900,000 EUR, indicating a strengthening balance sheet despite the expansion of its asset base.
5.  **Market Presence:** As a large-scale, established French "Société anonyme" with significant revenue (42,885,300,000 EUR), Veolia possesses the financial scale and the demonstrated history of managing complex capital structures (including the integration of Suez) required to issue hybrid bonds.

Given the existing successful utilization of hybrid securities, positive earnings trajectory, and strong cash flow generation, the company is well-positioned to issue additional hybrid debt.
