Terna S.p.A. is **Strongly Suitable** for hybrid bond issuance.

Terna is a regulated electricity transmission infrastructure operator in Italy, with characteristics that are highly compatible with the hybrid bond market: predictable regulated cash flows, very large asset base, strong capital-market access, and a substantial investment program.

Key factors supporting suitability:

- **Regulated utility / essential infrastructure profile:** Terna operates Italy’s national electricity transmission network, a natural-monopoly infrastructure business. This aligns strongly with the sectors most suitable for hybrids under the guidance: regulated utilities and infrastructure-like businesses with highly visible cash flows.

- **Stable and growing operating performance:**  
  Revenue increased from **€2.53bn in 2021 to €2.90bn in 2022**, while operating profit rose from **€1.20bn to €1.33bn**. Net profit also improved from **€791m to €858m**. This indicates resilient earnings despite a more difficult rate environment in 2022.

- **Strong cash generation:**  
  Operating cash flow increased materially to **€2.32bn in 2022**, compared with **€832m in 2021**. Even after heavy investment spending, the company has clear underlying cash-flow capacity.

- **Large capex funding rationale:**  
  Terna is capital intensive, with 2022 purchases of property, plant and equipment of about **€1.49bn** and intangible asset investment of **€212m**. Regulated grid expansion and energy-transition-related investment create a strong strategic rationale for hybrid capital as a long-term funding instrument.

- **Hybrid issuance already proven and accepted:**  
  The company issued or recognized **€989m of perpetual hybrid bonds/equity instruments** in 2022. This is a very important positive signal: Terna already has market precedent, investor familiarity, and accounting/rating-agency treatment consistent with hybrid capital.

- **Material leverage support:**  
  Total borrowings remain large, with long-term borrowings of **€8.42bn**, short-term borrowings of **€444m**, and current portions of long-term debt of **€1.91bn** at year-end 2022. Hybrid capital can provide meaningful equity credit and support adjusted leverage, which is particularly relevant given the company’s ongoing capex cycle.

- **Improved equity base:**  
  Equity increased significantly from **€4.71bn to €6.17bn**, partly due to hybrid issuance. This demonstrates that hybrids can materially strengthen the capital structure and rating headroom.

- **Investment-grade-like issuer profile:**  
  Terna’s regulated monopoly status, profitability, liquidity, and capital-market access are consistent with an investment-grade utility profile. It is not a cyclical, distressed, commodity-exposed, or speculative growth issuer.

- **Supportive ownership and strategic importance:**  
  The ultimate parent is **Cassa Depositi e Prestiti S.p.A.**, with CDP Reti as parent entity. This reinforces Terna’s strategic national infrastructure role and likely supports investor confidence.

Points to monitor:

- Interest rates rose sharply in 2022, increasing the cost of hybrid issuance versus 2020–2021. However, Terna’s business profile and investor access should mitigate this.
- The company already issued a sizeable hybrid in 2022, so additional issuance should be sized carefully to avoid overreliance on hybrid equity credit.
- Dividend distributions are meaningful, but this is common for regulated utilities and does not undermine the overall suitability given strong earnings and operating cash flow.

Overall, Terna fits the strongest hybrid issuer archetype: a large, regulated, investment-grade utility with predictable cash flows, substantial capex needs, and demonstrated access to the hybrid capital market.
