Second Quarter 2026 Highlights

NuScale’s exclusive global strategic partner, ENTRA1 Energy ("ENTRA1"), continues to advance discussions with the Tennessee Valley Authority ("TVA") toward a definitive power purchase agreement for potentially the largest nuclear power deployment program in U.S. history

NuScale is working with S.N. Nuclearelectrica S.A. ("Nuclearelectrica") and RoPower Nuclear ("RoPower") to satisfy conditions attached to Nuclearelectrica shareholders’ vote to advance the RoPower project in Doicești, Romania, which would deploy six NuScale Power Modules^TM ("NPMs") at a former coal plant site and represents the most advanced SMR effort in Europe

NuScale awarded Paragon, a leading supplier of safety-related products, a contract to complete final design development of the Highly Integrated Protection System ("HIPS") for the NuScale Power Module – a critical milestone in the Company's supply chain readiness

NuScale ended the second quarter with a strong liquidity position of $1.9 billion in cash, cash equivalents and short- and long-term investments to support near-term commercial readiness

NuScale Power Corporation (NYSE:SMR) ("NuScale", "NuScale Power" or the "Company"), the industry-leading provider of proprietary and innovative advanced SMR nuclear technology, today announced results for the quarter ended June 30, 2026.

"As demand for clean, reliable power grows more urgent by the day, the question for off-takers is no longer whether to go with nuclear — it is which technology can actually deliver, and when," said John Hopkins, NuScale President and Chief Executive Officer. "At NuScale, we have spent years doing the work that makes near-term deployment possible, and that work is now substantially complete. We hold the only U.S. Nuclear Regulatory Commission design certification in the SMR industry, our technology runs on fuel that is proven and available today, and we have built a supply chain of more than 60 specialized partners with over 30 agreements already executed. No one is better positioned to deliver carbon-free, 24/7 power on the shortest possible timeline."

Liquidity & Capital Resources

Ended the second quarter of 2026 with cash, cash equivalents, and short- and long-term investments of $1.9 billion.

Financial Update

Revenue and cost of sales decreased by $8.0 million and $6.0 million, respectively, during the three months ended June 30, 2026, as compared to the same period in the prior year, primarily due to the revenue recognized from the work associated with the Fluor Front-End Engineering and Design ("FEED") Phase 2 engineering services in support of the RoPower project, which was completed in late 2025, with no comparable activity in 2026.

Research and development ("R&D") expenses increased $6.6 million during the three months ended June 30, 2026, as compared to the same period in the prior year, primarily as a result of $7.1 million higher costs associated with the Company’s increased activities to advance the technological readiness and design maturity of our NPM components, partially offset by $0.6 million in lower regulatory costs as we received SDA approval in May 2025.

General and administrative expenses ("G&A") increased $4.4 million during the three months ended June 30, 2026, as compared to the same period in the prior year, primarily due to $1.2 million of higher personnel and equity-based compensation costs due to increased headcount and $3.9 million of higher organizational costs, partially offset by $1.0 million of lower legal fees now that the initial costs associated with becoming a large accelerated filer have passed.

Other expenses increased $8.0 million during the three months ended June 30, 2026, as compared to the same period in the prior year, primarily due to (a) the Company’s engineers and project personnel working on fewer commercial projects than in the prior year, resulting in the lower allocation to cost of sales described above and (b) higher other compensation costs incurred as we have ramped up the resources supporting supply chain readiness and the delivery of future commercial projects.

Investment income increased $8.5 million during the three months ended June 30, 2026, as compared to the same period in the prior year, primarily as a result of the Company’s stronger cash position and higher investments in cash equivalents, short-term investments and long-term investments.
