- VERBUND AG is a regulated electricity utility in Austria with extensive asset base and regulated cash flows, high visibility of earnings, and large-scale infrastructure-like operations. 
- S&P/Moody’s indicators provided: S&P Net Debt/EBITDA 1.6 in 2022 (solid but not excessive), FFO/debt 0.5174 (stable but not very high), Moody’s adjusted leverage trend deteriorating (negative signal). These suggest a reasonable but not pristine credit profile; hybrid instruments could help improve leverage headroom if used prudently.
- The company has not previously issued hybrid bonds (stated: no previous hybrids), which is a negative signal under the guideline that no prior issuance/origin suggests Not Suitable or at most Marginally Suitable. However, utility status and regulatory cash flows can support suitability if used for refinancing/ capex funding and to maintain rating headroom.
- Market backdrop: long-term rates in 2020-2022 show rising swap curves; however, for a regulated utility, hybrids can be attractive for funding needs if rating impact is favorable.

Assessment:
- Strengths for Strongly Suitable: regulated utility with high visibility, potential to improve leverage and funding for capex; credible access to institutional markets; infrastructure-like business model.
- Weaknesses/uncertainties: No prior hybrid issuance (counts against strongly suitable; typical guidance says absence is a strong signal Not Suitable or Marginally Suitable). Also rating metrics show a deteriorating leverage trend and FFO/debt around 0.52 which is modest; hybrids would be used to improve headroom but may not dramatically transform credit unless used aggressively.
- Given the combination: Regulatory visibility supports suitability, but lack of history with hybrids and deteriorating leverage trend push toward Marginally Suitable rather than Strongly Suitable.

Conclusion: Marginally Suitable.
