Fervo Energy Company Class A common stock143% improvement in drilling rates and 70% reduction in drilling time at Cape Station, with Gen 3.0 design reaching hotter rock and longer laterals, lowering capital intensity and improving unit economics.

Fervo Energy shares rose 14.1% on Thursday after the company reported a 143% improvement in drilling rates at its Cape Station geothermal development. The Sawtooth 7 well reached a measured depth of 19,448 feet with a 7,500-foot lateral in just 21 days, a 70% reduction in drilling time compared to its first commercial horizontal well. The well uses Fervo's more complex Generation 3.0 design, reaching hotter 460°F rock with longer laterals and larger casing while matching the 21-day timeline of the simpler Phase I design. Shorter drilling times can lower capital intensity and help Fervo move closer to its target of reducing installed costs from an expected $5,500 per kilowatt at Cape Phase II toward $3,000 per kilowatt over time. CEO Tim Latimer said the momentum from initial Phase II drilling supports expectations that the 3.0 well design will produce substantially more megawatts per well and significantly improve the unit economics of future GeoBlocks.
