A2A S.p.A. is a multi-utility operating in Italy, providing essential infrastructure services in the power, gas, and water sectors. This positions the company squarely in the "Regulated Utilities" category, which is a prime candidate for hybrid bonds due to highly visible and stable cash flows. 

Looking at the financial metrics for the fiscal year ended December 31, 2022, A2A shows an EBITDA of €1.505 billion and a total debt (proxied by other noncurrent and current financial liabilities) of approximately €6.889 billion. This implies a gross leverage ratio of around 4.6x and an FFO-to-Debt ratio in the low-to-mid 20s percentage range. These metrics are broadly indicative of a 'BBB' category Investment Grade profile, which is the sweet spot for hybrid issuance. 

The company has significant refinancing and capex funding needs. In 2022, proceeds from borrowings were €4.339 billion against repayments of €2.779 billion, while capital expenditure on property, plant, and equipment, and intangible assets reached €1.24 billion. Hybrid bonds would provide an effective tool to manage this funding requirement while materially improving adjusted leverage and FFO/debt metrics, thus preserving or improving its rating headroom. 

Additionally, A2A's track record of paying consistent dividends (€302 million in 2022) demonstrates a strong commitment to shareholder returns and a stable financial policy, which aligns well with the equity-like characteristics required by hybrid bond investors. Because it is a regulated utility with an IG profile and active financing/capex needs, a hybrid bond would serve as a core recurring funding instrument rather than an opportunistic or desperate measure.
