Ormat Technologies has priced an upsized $875 million convertible senior notes offering, increasing the originally announced $750 million transaction following strong investor demand.
The company will issue $725 million of 1.50% Series A notes and $150 million of 0.00% Series B notes, both maturing in 2031, according to the company’s pricing announcement. (see full release)
The offering follows an initial proposal announced one day earlier for $600 million Series A notes and $150 million Series B notes. (see original announcement)
Strong investor demand drives upsizing
The increase in the deal size signals robust institutional demand for Ormat’s convertible debt offering.
Convertible notes combine features of debt and equity, allowing investors to receive fixed income while retaining the option to convert into shares at a later stage. In this case, the notes carry an initial conversion price of about $140.40 per share, representing a 30% premium to the company’s share price at the time of pricing.
The terms are notable. The 1.50% coupon for the Series A notes and 0.00% for the Series B notes suggest investors were willing to accept relatively low yields in exchange for potential upside exposure to Ormat’s equity.
The company expects net proceeds of approximately $853.6 million, which will be used in part to repurchase about $285.9 million of its 2027 convertible notes, fund share buybacks, and support general corporate purposes.
Balance sheet management and growth positioning
A significant portion of the proceeds will go toward refinancing existing debt, effectively extending maturities and managing dilution.
Ormat plans to:
- Repurchase a portion of its 2.50% convertible notes due 2027
- Allocate around $25 million to share repurchases
- Use remaining funds for general corporate activities
This combination of refinancing and capital raising reflects a broader strategy to optimize the balance sheet while maintaining flexibility for future growth.
A signal for geothermal capital markets
Beyond Ormat itself, the transaction provides an important signal for the geothermal sector.
Ormat is one of the few publicly listed geothermal-focused companies with:
- A global operating portfolio
- Stable revenue streams
- Integrated capabilities across development, manufacturing, and operations
As of its latest disclosures, Ormat operates a 1,835 MW total generating portfolio, including geothermal, solar, and energy storage assets.
The successful upsizing of the offering indicates that public market investors are willing to allocate significant capital to geothermal, but primarily to companies with established track records and operating assets.
Positioning within a broader financing landscape
The deal comes at a time when geothermal financing is evolving across both public and private markets.
Recent developments include:
- Controlled Thermal Resources’ planned public listing via SPAC, implying a multi-billion-dollar valuation
- Fervo Energy’s $462 million Series E funding round to support large-scale enhanced geothermal development
These transactions reflect different financing pathways emerging in the sector:
- Public market financing for established operators like Ormat
- Private capital funding for growth-stage technology players like Fervo
- Hybrid equity stories combining geothermal with minerals or other assets, as seen with Controlled Thermal Resources
Implications for IPOs and geothermal valuations
Ormat’s financing adds an important reference point for how capital markets currently evaluate geothermal companies.
The transaction suggests that investors are prioritizing:
- Proven operating performance
- Contracted revenue streams
- Scalable platforms with diversified assets
This has implications for companies considering public listings. While investor interest in geothermal is growing, access to capital remains selective and closely tied to risk profile.
Early-stage developers and exploration-heavy projects may continue to face challenges in accessing similar financing conditions.
A maturing investment narrative for geothermal
The upsized offering reinforces a broader shift in how geothermal is viewed in financial markets.
Rather than being treated purely as a niche renewable segment, geothermal is increasingly positioned as:
- A source of firm, dispatchable power
- A complement to variable renewables
- A potential solution for growing electricity demand, including from data centres
At the same time, the Ormat transaction highlights that capital is flowing first to de-risked, scalable platforms, rather than uniformly across the sector.
