Hybrid bonds typically require stable profitability, strong equity, and appropriate debt capacity with some buffers. From the provided data:
- The company shows positive profit for the year with Profit Loss Attributable To Owners Of Parent 111,771,000 EUR and Comprehensive Income 209,853,000 EUR, indicating earnings stability.
- Equity stands at 1,517,534,000 EUR in 2023, with Issued Capital 667,191,000 EUR and Retained Earnings 241,987,000 EUR. Debt levels: Long-term borrowings 1,695,362,000 EUR (2023) and current borrowings 638,944,000 EUR. Total liabilities 4,934,062,000 EUR. Leverage appears moderate, but hybrid instruments require cushion for losses; there is still healthy equity base.
- Cash flows: Cash flows from operating activities 613,466,000 EUR (positive), investing and financing activities show sizable outflows, but operating cash flow supports servicing.
- No material impairment concerns indicated; impairment reversals small; tax expense manageable.

However, there is a large asset related to Transitional Gas Price Stabilization Regime Decree Law 84D2022 recognized as a liability/asset (1,000,000,000 EUR) in 2023 and 2022. This is a regulatory-related item that could affect stability and may introduce complexity and potential volatility to earnings.

Overall, given solid earnings, positive cash flow, reasonable equity cushion, and manageable dividends, but with regulatory regime exposure and significant borrowings, the company seems capable of supporting hybrid equity instruments, though not exceptionally strong. Therefore: Marginally Suitable.
