CORVALLIS, Ore.--(BUSINESS WIRE)--May 7, 2026-- 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 first quarter ended March 31, 2026.

“The demand for reliable, carbon-free power has never been greater, and NuScale is the only SMR technology provider with a U.S. Nuclear Regulatory Commission (“NRC”) approved design, an established supply chain and NPM components currently in production for commercial use to meet this essential need. We ended the first quarter with $1 billion in liquidity, expanded our supply chain partnership with Framatome and saw continued progress on the TVA program. We are building the infrastructure that this pivotal moment requires,” said John Hopkins, NuScale President and Chief Executive Officer.

Liquidity & Capital Resources

• Ended the first quarter of 2026 with cash, cash equivalents, and short- and long-term investments of $1.0 billion.

Financial Update

• Revenue and cost of sales decreased by $12.8 million and $5.8 million, respectively, during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to the revenue recognized from the RoPower technology license agreement (“TLA”) completed during the first three months of 2025 as well as the work associated with the Fluor’s 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 $3.7 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily as a result of $5.7 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 $1.9 million in lower regulatory costs as we received SDA approval in May 2025.

• General and administrative expenses (“G&A”) increased $1.6 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to $1.4 million of higher compensation costs due to increased headcount and $1.1 million of higher organizational costs, partially offset by $1.1 million of lower accounting and legal fees now that the initial costs associated with becoming a large accelerated filer have passed.

• Other expenses increased $10.0 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, 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 $5.6 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily as a result of the Company’s stronger cash position and higher investments in cash equivalents, short-term investments and longer-term investments.
