Fervo Energy (FRVO) Q3 2026 earnings review
Fervo starts first power plant, and Google signs huge contract
Fervo Energy, a developer of underground geothermal power plants, turned on its first commercial unit and locked in a major customer contract. Chief executive Tim Latimer announced a 396-megawatt agreement with Google that lifted contracted backlog by 65% to $11.9 billion, while the first 33-megawatt unit at Cape Station started commercial operation ahead of its fourth-quarter target. Management cut its second-half capital spending plan by $150 million after third-quarter spending of $257 million fell below what the old plan pointed to, though fourth-quarter spending still rises to about $475 million by our math.
| Contracted revenue backlog | $11.9B +65% from last quarter ($7.2B) |
|---|---|
| Contracted capacity | 1,054 MW +60% from last quarter (658 MW) |
| Q3 capital spending | $256.7M +13% from last quarter |
| Second-half capital spending outlook | Cut $150M middle of the range: $725M vs $875M prior |
⚖️ Verdict: 🟢 Bullish
The story got better because two major execution risks eased in the same quarter: the first utility-scale power plant started commercial operation ahead of schedule, and the non-binding Google framework converted into a binding 15-year contract with a 600-megawatt data center option. One caution: the company still withholds well-level temperature and flow data, and project-level partners absorbed all $30 million of the quarter's tax credit benefit, leaving common shareholders with a net loss.
The question now is whether the underground wells at Cape Station hold their heat and flow rates over a full year of commercial operation without needing costly extra drilling. If the rock stays hot, the $5,500 per kilowatt cost target for the Google phase holds; if it cools quickly, extra wells will drain the post-IPO cash cushion. Full-year revenue from the first three units and well data in the annual filing will tell.
🐂 Bull Case
Google Deal Expands Backlog by 65%
Fervo builds enhanced geothermal plants that pump water through hot underground rock to generate electricity. Contracted backlog, the total revenue locked in under signed power purchase agreements (PPAs), had stayed unchanged at $7.2 billion last quarter. Chief executive Tim Latimer announced what he called the "largest enhanced geothermal power purchase agreement to date" with Google, ending the pause in new contracts.
- New Google contract: 396 megawatts over 15 years across GeoBlocks 4 through 11, starting mid-2028
- Total contracted capacity: 1,054 megawatts worth $11.9 billion, up 60.2% in megawatts and 65.3% in dollars from last quarter
- Implied contract price: about $98 per megawatt-hour by our math, assuming 92.5% plant availability
- Expansion option: 600 megawatts that could "directly power a potential regional data center in Beaver County, Utah"
This agreement matters because it turns an earlier non-binding framework with Google into guaranteed take-or-pay revenue for Cape Station's second phase. The 600-megawatt option also creates a clear path for behind-the-meter delivery, where power goes straight to a data center without waiting on congested utility power lines.
What to watch: whether Google exercises the 600-megawatt Utah data center option under the state's direct-to-load framework. A signed agreement would lock in the capacity needed for the geothermal developer's 2030 installation target.
First Cape Station Unit Starts Commercial Operation Early
"In the third quarter, Cape Station achieved a major milestone, reaching first power and contractual commercial operation," chief executive Tim Latimer said. The power producer had previously targeted the fourth quarter for first electricity from GeoBlock 1, its first 33-megawatt power unit in Utah. Instead, it declared commercial operation on September 30, ahead of its contractual deadline.
Commissioning the remaining two units of Phase I is also moving on schedule. GeoBlock 2 has connected to the power grid and is exporting test electricity, while GeoBlock 3 has finished mechanical construction and is in cold testing. Both 33-megawatt units remain on track to reach commercial operation by January 1, 2027, bringing total operating capacity from 36 megawatts today to about 102 megawatts.
Starting the first unit on time eases the risk of construction delays at the company's first utility-scale project. It also unlocked a $29.9 million tax credit benefit this quarter and keeps fourth-quarter revenue on plan.
What to watch: fourth-quarter electricity sales in the full-year report, the first full quarter of revenue from GeoBlock 1. Steady revenue above $3 million would confirm that the plant runs at its expected commercial output.
Deeper Wells Nearly Double Cape Station Resource Estimate
Fervo drills horizontal wells into hot rock using its 3.0 well design, which reaches deeper underground and uses wider pipes than its first phase. An independent study by consulting firm DeGolyer and MacNaughton raised Cape Station's estimated power potential to 8.4 gigawatts, nearly double the previous 4.3-gigawatt estimate. That helped lift the early development pipeline by 12.6% from last quarter to 54.7 gigawatts across 670,000 acres.
Construction on the 400-megawatt second phase, now called Cape Google 400, is advancing on the ground and underground. Drilling for those eight power units is 18% complete, up from about 10% last quarter, while the first 50-megawatt turbines passed factory testing. Management still targets an installed cost of $5,500 per kilowatt for this phase, down from $7,000 per kilowatt on Phase I.
What to watch: the subsurface drilling completion percentage for Cape Google 400 in next quarter's update. Reaching 30% or more by year-end would show the rigs can finish the wellfield well ahead of the mid-2028 startup.
🐻 Bear Case
Public Data Still Cannot Verify Underground Well Performance
Fervo stated that its first 33-megawatt unit at Cape Station is "operating in line with expectations for production and power delivered" under its customer contract. However, the press release provides no well-level figures for water flow rates, underground rock temperature decline, water loss, or seismic activity.
Moreover, the developer declared commercial operation on September 30, the final day of the quarter. That means GeoBlock 1 had less than six weeks of commercial operation before this report, which is too short to test how fast the underground rock cools over time. Meanwhile, the company transferred $514.3 million from construction into active property, plant and equipment, noting that Phase I remains on its $7,000 per kilowatt budget.
This gap matters because enhanced geothermal returns depend on how long underground fractures stay hot before requiring extra makeup wells. Without public flow and temperature numbers, investors must take management's word that the reservoir is holding up.
What to watch: well-level flow and temperature data in the upcoming quarterly filing or after the November 19 investor site tour. Continued silence once all three Phase I units run in early 2027 would keep reservoir depletion as the primary risk.
Project Partners Take First Claim on Cape Station Profits
Fervo funded part of Cape Station Phase I by selling preferred project stakes, listed on the balance sheet as redeemable noncontrolling interests. This quarter the company reported total net income of $11.7 million, only because GeoBlock 1's startup triggered a one-time $29.9 million tax credit benefit and interest rate swaps added an $11.8 million non-cash gain. Without those two one-offs, the company lost $30.1 million by our math.
Even with the tax benefit, common shareholders saw a net loss of $20.8 million, or $0.07 per share. Project partners absorbed $31.2 million of net income through their redeemable noncontrolling interests, pushing their balance sheet claim up 17.4% from last quarter to $219.5 million. Because these project-level investors have priority rights to Cape Phase I cash flows and tax benefits, early plant profits do not reach the parent company.
What to watch: the income allocated to redeemable noncontrolling interests in the fourth quarter when GeoBlocks 2 and 3 finish commissioning. Another large allocation would show that project-level payouts will absorb most of Phase I's early earnings.
Second-Half Spending Cut Pushes Construction Bills Into Next Year
Capital expenditures, the cash spent on drilling wells and building power plants, reached $256.7 million in the third quarter, up 13.3% from the second quarter. That was 41.3% below the $437.5 million quarterly pace implied by our math from the company's prior second-half plan. In response, management cut its second-half capital spending outlook by $150 million at the middle of the range, to $700 million to $750 million.
The company said construction efficiencies allowed some Cape Google 400 spending to happen "later in the construction cycle, with no change to expected commercial operation dates or total expected investment". Because total project cost did not drop, the $150 million is deferred into 2027 rather than saved, and fourth-quarter spending must still jump 85% at the middle of the range to $475 million.
What to watch: full-year 2027 capital spending plans when management issues next year's budget. A step-up above $1.8 billion would confirm that deferred 2026 bills are stacking onto next year's cash burn.
Risks this quarter didn't answer
Four standing concerns from our prior analysis received no new numbers in the third-quarter press release.
- 2027 grid curtailment: management held its 2027 revenue outlook unchanged without stating how many months power line limits will cap Cape Phase I output.
- Phase II permitting: the release gave no update on how many of the remaining 97 permits for Cape Google 400 have been approved.
- Tax credit financing rules: no disclosure on whether the $29.9 million tax benefit satisfies the Project Granite loan thresholds.
- Founder voting control: 7.8 million Class B shares with 40 votes each still give the founders control over 287.1 million Class A shares.
👓 Other Themes
Federal Grants Back Appraisal Drilling in Two States
The U.S. Department of Energy selected the geothermal developer for two potential grant awards totaling about $20.0 million to help fund new appraisal wells in Idaho and Nevada. While the grants depend on final government agreements and represent less than atenth of one quarter's capital budget, they lower the cost of testing early-stage land outside Utah as fourth-quarter appraisal drilling begins.
💲 Other KPIs
Overhead costs rose 43.5% from last quarter andnearly fivefold from $8.1 million a year ago. Management cited higher stock-based pay, public company expenses, and new hires. Because the first power unit only started on the last day of the quarter, this overhead expansion pushed the operating loss to $43.7 million, up from $28.7 million in the second quarter.
Unrestricted cashplus $11.0 million of restricted cash fell 9.0% from $2.12 billion last quarter as the company funded Cape Station construction. Total debt rose 32.0% from $228.4 million in the second quarter as the developer drew down its project loan facility. By our math, net cash stands at $1.61 billion, enough to cover roughly three quarters of the planned fourth-quarter spending rate.
Net property, plant and equipment jumped 88.1% from $793.2 million at the end of 2025. When GeoBlock 1 entered service on September 30, the company moved $514.3 million out of construction-in-process into active plant assets. That figure includes shared wellfield infrastructure and financing costs that will also serve GeoBlocks 2 and 3.
🔮 Guidance
New. The plan calls for $475 million of capital spending at the middle of the range, an 85.0% jump from the third quarter's $256.7 million as drilling and surface work ramp up on Cape Google 400 and the final Phase I units.
Cut. Management lowered the second-half range by $150 million, or 17.1% at the middle of the range, after third-quarter spending came in at $256.7 million. By our math, that puts full-year 2026 capital spending at $1.12 billion and leaves a $248.5 million first-quarter 2027 residual under the older $1.2 billion rolling budget. Total project investment is unchanged, so the unspent $150 million shifts into future periods.
Unchanged. The company kept its fourth-quarter and 2027 revenue plans where they were, noting that the fourth quarter will mark the first full quarter of electricity sales from Cape Station GeoBlock 1. Holding the 2027 outlook means the previously flagged grid curtailment risk for next year has neither worsened nor cleared.
❓ Key Questions
Will Fervo publish well flow and temperature decline data?
GeoBlock 1 is now in commercial operation, and management plans an investor tour on November 19 with no new disclosures. Without well-level flow rates and temperature trends, investors cannot verify whether the underground reservoir is performing on plan.
How much does the Google deal shift 2027 capital spending?
Deferring $150 million of second-half 2026 capital spending without lowering total project costs means those bills move into 2027 or 2028. Investors need the 2027 budget to see how fast the $1.9 billion cash balance will be spent.
When will project partners' priority claim on Phase I end?
Redeemable noncontrolling interests absorbed $31.2 million of income in the third quarter, leaving a loss for common shareholders despite a $29.9 million tax credit benefit. Clarifying how much of 2027's $60–80 million revenue stays with project partners is essential.
What is the timeline for Google's 600-megawatt expansion option?
The 600-megawatt behind-the-meter option in Beaver County would be the first project under the 3-gigawatt Google framework and would bypass grid congestion. Management did not state when Google must decide on the option.
