Fervo Energy seeks up to $7.37 billion valuation in larger IPO

Fervo Energy moved to the center of the clean-power market on Monday, seeking up to a $7.37 billion valuation in an upsized U.S. initial public offering that would test whether geothermal can command the same investor enthusiasm once reserved for solar and wind. The Houston-based developer now plans to raise as much as $1.82 billion by selling 70 million shares at $25 to $26 each.

The larger deal signals stronger demand than Fervo first expected and gives investors a fresh way to price one of the most capital-intensive corners of the energy transition. Fervo, founded in 2017, has built its pitch around adapting shale-era horizontal drilling and fiber-optic sensing to geothermal power, a model designed to make round-the-clock carbon-free electricity more scalable and competitive. Its IPO filing was first submitted to the U.S. Securities and Exchange Commission on April 17, 2026, and updated on May 4, May 8 and May 11.

At the heart of the offering is Cape Station, Fervo’s flagship project in Beaver County, Utah. The company says the development is designed for 500 megawatts and that Phase I remains on track to deliver power by late 2026, reaching about 100 megawatts of operating capacity by early 2027. Phase II is targeted for 2028. Fervo says Cape Station could create more than 200 temporary construction jobs and 15 to 30 permanent on-site jobs, with the project benefiting from existing transmission infrastructure near Milford, Utah.

The company is also leaning on high-profile commercial validation. Google said in November 2023 that its geothermal project with Fervo was operational and delivering carbon-free electricity to the grid serving Google’s Nevada data centers. In June 2024, Google and NV Energy sought approval for a Clean Transition Tariff tied to Fervo’s 115-megawatt Corsac Station enhanced geothermal project, underscoring how the company’s technology is being tied to data-center demand and new utility buying structures.

Fervo entered 2026 with momentum after announcing an oversubscribed $462 million Series E on December 10, 2025, led by B Capital. In that deal, Fervo said Cape Station would provide 100 megawatts beginning in 2026 and another 400 megawatts by 2028, while B Capital’s Jeff Johnson said surging AI and electrification demand requires scalable always-on power. A Stanford-hosted paper last year also said Fervo’s first eight horizontal enhanced-geothermal wells showed significant performance improvements.

The IPO will help determine whether investors see Fervo as a genuine utility-scale power developer, or as a premium clean-tech story still asking markets to underwrite a technology that must prove it can scale. For geothermal, the answer could decide whether the sector finally breaks out of climate promise and into mainstream infrastructure finance.
