To determine whether VERBUND AG is suitable to issue hybrid bonds, we evaluate its financial profile, industry characteristics, and debt capacity based on the provided 2022 annual report data.

1. **Industry & Business Model**: 
   VERBUND AG is a large utility company (as evidenced by its "Revenue From Sale Of Electricity" of €8.75 billion and "Grid Revenue" of €1.31 billion). Utilities are generally prime candidates for hybrid bond issuance because they have stable, predictable cash flows and high capital expenditure (CAPEX) requirements. Hybrid bonds help them fund these large infrastructure projects while maintaining their senior credit ratings.

2. **Profitability and Cash Flow**:
   The company exhibits massive profitability with an EBITDA of €3.16 billion and a Net Profit of €1.95 billion for 2022. Operating cash flows are exceptionally strong at €2.02 billion, which comfortably supports its investing activities (cash outflow of €1.59 billion). This healthy free cash flow generation provides strong assurance to subordinated bondholders.

3. **Leverage and Solvency**:
   Looking at the company's debt position for the end of 2022 (2023-01-01), the Noncurrent Financial Liabilities are €2.84 billion and Current Financial Liabilities are €1.11 billion, totaling roughly €3.95 billion in interest-bearing debt. With an EBITDA of €3.16 billion, the Debt-to-EBITDA ratio is approximately 1.25x. This is extremely low leverage for a capital-intensive utility company. Furthermore, the company's total equity stands at €8.32 billion against total assets of €19.16 billion, representing a robust equity ratio of over 43%.

4. **Interest Coverage**:
   With an EBITDA of €3.16 billion and interest expenses of just €101.7 million, VERBUND AG's interest coverage ratio is over 31x. This indicates an overwhelming ability to service its existing debt obligations, making the addition of hybrid (subordinated) debt easily manageable.

**Conclusion**:
VERBUND AG features low leverage, exceptional interest coverage, a massive and stable equity base, and operates in a defensive, cash-generative sector (utilities). Investors would have an extremely high appetite for subordinated debt from an issuer with such a pristine balance sheet. The company is in a prime position to issue hybrid bonds should it wish to optimize its capital structure or fund further expansions while preserving senior debt capacity.
