Ormat's Q2 Beat Looks Real: 10.6% Revenue Growth, Raised Guidance, and One Clean Write-Off

Geothermal delivered the quarter; the write-off may have improved the quality of the numbers

Ormat's second quarter looks grounded. The company delivered 10.6% Q2 revenue growth, reporting $258.8 million in revenue and $0.43 diluted EPS, then reinforced that result by raising full-year 2026 revenue guidance to $1.15 billion to $1.2 billion. That combination suggests the first half was more than a one-quarter bump.

Why the $6.6 million storage write-off matters

The quarter also included a $6.6 million write-off tied to storage projects it decided not to pursue. Rather than masking poor pipeline quality, that charge makes the operating picture cleaner. Management is walking away from weaker storage opportunities instead of forcing them.

That distinction matters because geothermal remains the durable base, while storage is still the more discretionary part of the mix. Even with the higher outlook, Ormat only expects energy storage revenue of $140 million to $155 million for the year. The core business is still the baseload geothermal platform.

Operating drivers, not accounting tricks, explain the growth

The quarter looks credible because the growth traces back to clear operating levers.

What drove revenue

Growth came from the Blue Mountain acquisition, well field optimization at Olkaria, and reduced U.S. curtailments. That is an important mix of drivers: acquired capacity, better output from existing wells, and fewer instances of curtailed power.

Margin mix: geothermal as the base, storage as the upside

Electricity gross margin was 23.7%, while energy storage gross margin was 56.2%. The takeaway is straightforward: storage can improve the overall margin blend, but geothermal still anchors the business.

Management also highlighted that energy storage revenue nearly tripled due to high asset availability and the strategic capture of favorable merchant pricing in the PJM market. That is positive, but it does not change the larger point that geothermal remains the steadier engine.

Contract pricing is the part of the story investors should respect

One of the more constructive signals was management's comment that it is proactively renegotiating geothermal contracts well ahead of expiration to capture market pricing exceeding $100 per megawatt hour, compared to legacy rates of $86. For a business that supplies firm renewable power, that kind of pricing leverage matters more than short-term storage volatility.

Storage is improving, but the cleaner interpretation is that geothermal provides durability while storage adds upside when market conditions cooperate.

What could weaken the read

Not everything was clean. The product segment was hurt by the timing of manufacturing progress and increased construction costs for specific European projects. Management also said guidance assumes normalized merchant pricing in the second half of the year following a very strong Q2.

That leaves a simple scorecard:

• Strongest element: geothermal generation, with capacity additions and better field performance
• Positive but less predictable: energy storage, with stronger margins and better near-term pricing
• Watch item: product execution and how quickly those European project pressures ease

What investors should watch next

Ormat now has the raised full-year 2026 revenue and Adjusted EBITDA guidance and a clearer storage pipeline behind it. The next question is whether the project backlog is starting to look like future earnings rather than just future ambition.

The key numbers to watch are the 2028 portfolio target of 2.6–2.8 gigawatts and progress on EGS development. Management said EGS pilot projects at Desert Peak and Sage are scheduled to begin drilling in Q4 2026. That is the kind of tangible checkpoint investors need to see.

What would strengthen the thesis

Bulls do not need a euphoric quarter. They need evidence that the pipeline is converting into operating assets on schedule.

What would weaken the thesis

If future reports fail to show progress against those development milestones, or if product execution remains uneven, the story stays in the wait-and-see category rather than becoming a full rerating case.
