ENI appears suitable to issue hybrid bonds based on scale, profitability, cash generation, and balance sheet capacity.

Key positives:
- Very large issuer: total assets were €152.1bn at 2022 year-end, supporting capital markets access.
- Strong profitability in 2022: profit before tax was €22.0bn and net profit was €14.0bn, materially up from 2021.
- Strong operating cash flow: cash flow from operating activities was €17.5bn in 2022.
- Solid equity base: total equity increased to €55.2bn from €44.5bn, improving capitalization.
- Manageable leverage profile: total borrowings and lease liabilities were significant, but not excessive relative to EBITDA-like cash generation and equity. Current and noncurrent borrowings plus lease liabilities were roughly €31.9bn versus €55.2bn equity.
- Demonstrated access to subordinated/hybrid-type capital: the company previously issued perpetual subordinated bonds/equity instruments in prior years, suggesting market familiarity and structural suitability.
- Strong liquidity: cash and cash equivalents were about €10.2bn, with additional current financial assets at fair value through profit or loss of €8.3bn.

Main cautions:
- ENI operates in a cyclical and commodity-exposed sector, so earnings can be volatile, as shown by the large loss in 2020.
- Capital expenditure and shareholder distributions are substantial.
- Hybrid bonds would be useful to preserve credit metrics while funding investment or refinancing, but commodity cyclicality prevents a completely risk-free assessment.

Overall, the company’s size, profitability, cash flow, liquidity, and prior use of hybrid/perpetual instruments make it strongly suitable for hybrid bond issuance.
