Honestly, there is no mature unit-economics story to evaluate yet — revenue is nominal, so "unit economics" here has to mean project-level and drilling-level economics, not gross margin on a real P&L. Full-year 2025 revenue was $138,000 against a $57.8 million net loss, and Q1 2026 revenue was $61,000 against a $31.8 million net loss; there is no meaningful revenue base to compute a margin trend from, and it would be misleading to describe one.
The real unit-economics lever the report tracks is cost per kilowatt of installed capacity. Phase II is guided toward about $5,500 per kilowatt, moving toward a long-term target of $3,000 per kilowatt, and the July 8 Sawtooth 7 well matched Fervo's fastest Phase I drilling pace despite being deeper and hotter — evidence the learning curve is compounding in the right direction. Because PPA pricing is contracted and largely fixed, a falling cost curve is the main mechanism by which project-level returns improve as the company scales; this is a drilling-cost story, not a demand-elasticity or pricing-power story.
Capital intensity, however, is rising in absolute dollar terms even as per-unit costs improve, and both are true at once. Construction-in-process reached $972.0 million at March 31, 2026, Q1 2026 capex alone was $172.8 million, and management has guided to roughly $1.2 billion of capex from Q2 2026 through Q1 2027, with Phase II needing about $2.2 billion more through 2028. Essentially all available capital — the $280.8 million of cash on hand at March 31 plus roughly $2.043 billion of net IPO proceeds, undrawn Mercuria facilities, and about $294.6 million under Project Granite — is being deployed into growth capex: GeoCluster development, land expansion, working capital, and operating expenses, not debt service or shareholder returns. The March 2026 $421.4 million non-recourse project-financing package is itself capital being drawn down for Phase I construction, and management intends a large share of Phase II's $2.2 billion need to come from project-level debt rather than corporate cash — a funding plan, not yet a funding fact.
