Naturgy Energy Group appears to be a good hybrid-bond candidate, but the case is not unequivocally “strong” based on the data provided.

Key positives for hybrid suitability:

- Utility / energy infrastructure profile: Naturgy is a large integrated gas and power utility, with substantial regulated or infrastructure-like activities. This supports relatively visible cash flows compared with cyclical industrial or commodity pure-play issuers.
- Large scale and market access: Revenue was about €34.0bn in 2022, EBITDA about €5.0bn, total assets about €40.4bn, and cash was close to €4.0bn. This scale and liquidity indicate strong access to institutional capital markets.
- Solid operating recovery in 2022: EBITDA increased to €4.95bn from €3.53bn, operating profit rose to €3.08bn from €2.10bn, and net profit attributable to the parent increased to €1.65bn from €1.21bn.
- Strong cash generation: Operating cash flow improved materially to €4.24bn from €1.00bn, comfortably covering capex of about €1.69bn and supporting positive free cash flow before shareholder distributions.
- Hybrid bonds could provide rating/leverage support: Financial debt is meaningful, with noncurrent financial liabilities of €14.0bn and current financial liabilities of €2.3bn. A hybrid with partial equity treatment could improve adjusted debt metrics and rating headroom, especially given the capital-intensive utility profile.

Key constraints:

- Metrics are improving rather than deteriorating: Equity increased to €10.0bn from €8.9bn, EBITDA rose strongly, and operating cash flow improved significantly. This reduces the urgency for a hybrid as a rating-preservation tool.
- Leverage is manageable: Gross financial liabilities of about €16.3bn against EBITDA of €5.0bn implies gross debt/EBITDA around 3.3x before cash; net of €4.0bn cash, leverage looks closer to 2.5x. This is compatible with an investment-grade utility profile and does not indicate acute stress.
- High shareholder distributions: Dividends and equity-related cash outflows were significant, with €1.5bn paid in dividends/remuneration and €503m used for share acquisitions. Investors may view hybrid issuance less favorably if proceeds indirectly support distributions rather than capex, refinancing, or balance-sheet strengthening.
- Mixed business risk: Naturgy is not a pure low-risk regulated network utility. It has exposure to gas, power, commodity procurement, derivatives, and unregulated activities, which raises earnings and working-capital volatility relative to the strongest regulated utilities.
- Market conditions worsened in 2022: Euro swap rates rose sharply, with 5-year swaps averaging 1.73% and 10-year swaps 1.93%, while subordinated nonfinancial IG spreads also widened. Hybrid issuance would therefore be materially more expensive than in 2020-2021.

Overall assessment:

Naturgy has many characteristics that support hybrid issuance: utility status, large scale, investment-grade-like profile, visible cash flows, meaningful capital structure needs, and credible market access. However, the financial profile improved materially in 2022, liquidity is strong, and there is no clear evidence of urgent refinancing pressure, an approaching hybrid call, or deteriorating credit metrics requiring hybrid equity credit to preserve the rating. Therefore, hybrid issuance would likely be credible and useful, but more as an opportunistic balance-sheet/rating-headroom instrument than as a clearly necessary or strongly compelling funding tool.
