ENI S.p.A. is a large, integrated oil and gas company with substantial scale and diversified asset base, strong equity base, and solid earnings before tax in 2022 (Profit Loss Before Tax: 20.0B EUR; Profit Loss Attributable To Owners Of Parent: 13.887B EUR) alongside positive comprehensive income and robust cash generation from operations (Cash Flows From Used In Operating Activities: 17.46B). However, ENI operates in a highly commodity-driven sector (oil & gas), which introduces earnings cyclicality, commodity price exposure, and high capex needs. The company has a sizable net debt position with long-term borrowings and lease liabilities, and mixed liquidity metrics in the reported figures, though it maintains strong equity and large scale.

Regulatory/regulatory-like status: ENI is not a regulated utility; it is an integrated energy company with significant exposure to commodity cycles. The S&P-like framework provided targets regulated utilities and infrastructure-like entities as strongly suitable for hybrids due to visible cash flows. ENI’s business model lacks regulated cash-flow visibility; cash flows depend on commodity prices and market demand, which increases volatility relative to regulated utilities.

Ratings and funding rationale: ENI is investment-grade historically; by 2022, its market visibility and scale could support hybrids, but the equity and debt structure show substantial volatility in earnings and cash flow due to commodity cycles. Hybrid issuance could improve capital structure if used to support sustainable leverage headroom and reduce cost of capital, but given commodity exposure, market appetite for hybrids would depend on structural protections, covenants, and alignment with rating agency views.

From the guidelines:
- Strongly Suitable requires regulated/clear cash flows, improvement in adjusted leverage/FFO/debt, and strong financing policy credibility; plus a compelling reason (refinancing/M&A), or imminent call. ENI does not fit regulated-utility profile, and while it has strong cash generation, the lack of visible regulatory cash flow reduces the strength of a hybrid case.
- Marginally Suitable fits an industrial or infrastructure-adjacent with moderate cash-flow visibility; hybrid issuance would be opportunistic, not core; market access likely but pricing sensitive; could provide rating headroom.
- Not Suitable would apply if highly cyclical/commodity-pure-play with weak cash flow visibility or if there is no clear use of proceeds or strong rating headroom.

Given ENI’s high sensitivity to oil/gas cycles and absence of regulated cash flow certainty, plus hybrids potentially being viewed as expensive equity-like instruments for a cyclic, commodity-exposed large cap, the case seems more Marginally Suitable than Strongly Suitable. The instrument could be used opportunistically for refinancing or optimizing capital structure, but not as a core funding source with guaranteed rating headroom. Therefore: Marginally Suitable.
