Hybrid bonds require an issuer to have strong, stable cash flows, robust equity, healthy interest coverage, and manageable leverage to support the additional debt-like obligation while maintaining equity credit.  
Looking at VERBUND AG’s data:

- **Revenue and profitability:** Revenue more than doubled from ~€4.8B in 2021 to ~€10.3B in 2022. EBITDA grew from ~€1.58B to ~€3.16B. Net profit attributable to owners more than doubled to ~€1.72B.
- **Interest coverage:** Interest expense increased from ~€78M to ~€102M, but operating profit is ~€2.63B, giving extremely comfortable coverage (over 25x in 2022).
- **Cash flow:** Operating cash flow improved dramatically from ~€98M to ~€2.02B, showing strong cash generation capacity.
- **Balance sheet:** Total equity increased from ~€6.36B to ~€8.32B. Noncurrent financial liabilities increased, but equity is larger than total noncurrent liabilities.
- **Volatility risk:** There is significant volatility in OCI from cash flow hedges, which could affect equity quality, but the underlying profitability and cash flow remain strong.
- **Dividends:** They maintain a significant dividend payout, but retained earnings still grew strongly.

Overall, the company demonstrates strong credit metrics, robust earnings, and healthy cash flows necessary to service hybrid capital.
