ENGIE already has a meaningful hybrid component in its capital structure: “deeply subordinated perpetual notes” were €3.393bn at Dec. 31, 2022, down from €3.767bn a year earlier. Because S&P equity credit is capped at 15% of total adjusted capital, the starting point matters: ENGIE is not beginning from zero, but it also appears materially below the cap.

Key credit considerations:

- **Business profile is relatively strong and diversified.** ENGIE is a large European multi-utility with regulated networks, renewables, flexible generation, energy management, and supply activities. This supports scale, scope, and diversification. However, its earnings are not purely low-risk regulated utility earnings; energy management, supply, commodity and derivative exposures introduce volatility.
- **2022 earnings were highly volatile.** Revenue rose sharply to €93.9bn from €57.9bn, but current operating income including operating MTM fell to €4.3bn from €6.1bn, and profit from continuing operations was negative at -€1.8bn. Net profit was only €0.39bn, helped by discontinued operations. Comprehensive income attributable to owners was negative.
- **Cash flow was stronger than net income.** Operating cash flow improved to €8.6bn from €7.3bn, and operating cash flow before working capital was €12.4bn. This gives meaningful internal funding capacity.
- **Capex and investment needs remain material.** Purchases of PP&E and intangibles were €6.4bn, consistent with a capital-intensive utility/energy-transition profile. Free operating cash flow after capex was positive but not large once dividends are considered.
- **Leverage is not extreme, but balance sheet pressure exists.** Reported borrowings were about €40.6bn at year-end 2022, versus equity of €39.3bn. Equity declined from €42.0bn to €39.3bn, while liabilities increased. Finance costs rose materially to €3.7bn from €2.1bn.
- **Refinancing needs are moderate-to-high, not transformational.** Current borrowings were €12.5bn, and 2022 debt repayments were €11.0bn, indicating active refinancing requirements. However, cash was also high at €15.6bn and ENGIE generated positive operating cash flow.
- **Hybrid cost is now materially higher than in 2020–2021.** Euro swap rates moved sharply higher in 2022, and non-financial subordinated spreads also widened. Issuing hybrids would likely increase average funding cost relative to legacy debt, although for a large IG utility the cost may still be acceptable if it protects credit metrics.
- **Existing hybrids suggest market acceptance and capital-structure rationale.** ENGIE already uses deeply subordinated perpetual notes, so incremental issuance would be a continuation of an established capital policy rather than a new or unusual instrument.

Overall, ENGIE has a **moderate but clear rationale** to use hybrids: capital-intensive energy-transition investment, elevated refinancing activity, weaker 2022 earnings, lower equity, and higher finance costs all argue for preserving rating headroom. However, the case does **not** appear severe enough for the maximum 15% or near-maximum 11.25% bucket: liquidity is strong, operating cash flow is resilient, disposals supported funding, and there is no evidence of transformational M&A or imminent downgrade risk requiring very aggressive hybrid support.

Given the existing €3.4bn hybrid base and the practical issuance constraint of up to €3bn per year, a target around the **mid-range** is most appropriate. Incremental hybrid issuance over the next 18 months would meaningfully support adjusted leverage without overusing an expensive instrument in a higher-rate environment.
