Hera S.p.A. is a multi-utility company operating in the regulated utilities sector (water, gas, electricity). This aligns perfectly with the "Strongly Suitable" criterion of being a regulated utility or infrastructure-like business with highly visible and stable cash flows. 

Looking at the financial metrics for the fiscal year ended December 31, 2022:
- **Leverage**: Total Debt (Financial Liabilities) is approximately €6.34 billion, while Total Equity is €3.64 billion. This results in a Debt-to-Equity ratio of around 1.74x, which indicates a moderately leveraged profile typical of the BBB area (Investment Grade).
- **FFO to Debt**: Operating Cash Flow (before working capital changes) is roughly €1.2 billion. After adjusting for interest and taxes, Funds From Operations (FFO) is estimated around €900 million. This yields an FFO-to-Debt ratio of approximately 14-15%, which sits squarely in the 'BBB' category per S&P's methodology and leaves limited headroom above the 'BB' threshold.
- **Use of Proceeds**: Hera has significant capital expenditure requirements (€709 million in 2022 for property, plant, and intangible assets) and saw a massive increase in working capital needs (especially inventories and receivables, draining €927 million in operating cash flow). The issuance of a hybrid bond would provide a material improvement to adjusted leverage, FFO/debt, and rating headroom, satisfying a strong refinancing and capex funding rationale.
- **Market Conditions**: With the 5Y swap rate at 1.726% and sub-senior spreads around 2.295% in 2022, the cost of capital for hybrids is reasonable for an IG utility, and institutional investors have strong appetite for quasi-equity instruments from stable, regulated Italian multi-utilities.

Hera needs the hybrid capital to preserve its investment-grade rating amidst rising working capital and debt, and it fits the profile of a core recurring funding instrument for a utility. Therefore, it is strongly suitable.
