Hybrid bonds (deeply subordinated securities) suitability depends on capital structure, flexibility, leverage, credit metrics, and regulatory treatment. From data:

- The company has prior issues of deeply subordinated securities with positive activity: 2021-2022 shows entries for "Deeply Subordinated Securities" under equity movements and related instruments in 2022-2023. In 2022-01-01 to 2023-01-01 there are entries: "Contribution Of Hybrid Debt Suez SA" with Deeply Subordinated Securities Member Member 1623900000 EUR and corresponding Equity increase 1623900000 EUR; "Payment Of Hybrid Debt Deeply Subordinated Securities" with -500000000 EUR issued? It shows complex interactions including issuance and repayments. This indicates they have issued hybrid instruments previously.

- However, the equity structure shows large negative Consolidated Reserves/Retained Earnings (2023: -4082600000 EUR) and high equity attributable to owners of parent (2023: 12254700000 EUR). Noncontrolling interests 2612200000. There is substantial leverage: Noncurrent Liabilities 29233500000 EUR vs Equity 14866900000 EUR (2023). Debt levels appear high but hybrids could be used to optimize capital structure.

- They have experience with complex financial instruments and have engaged in issuance and repayment of deeply subordinated securities, suggesting familiarity and capability to manage hybrid instruments.

- Dividends per share and distributions exist; not directly impact hybrid suitability.

Overall, information suggests they have previously issued deeply subordinated securities and thus have some track record. Yet current leverage is high; may be marginally suitable rather than strongly suitable due to high leverage and large liabilities; but given prior experience with hybrids, and involvement in Suez acquisition context. I would say Marginally Suitable.
