Received ahead of schedule U.S. Nuclear Regulatory Commission ("NRC") Standard Design Approval for uprated 77 MWe design

Continued to progress Fluor's Phase 2 Front-End Engineering and Design ("FEED") study for the RoPower Doicești power plant

Maintained strong liquidity and financial position

NuScale Power Corporation (NYSE:SMR) ("NuScale", "NuScale Power" or the "Company"), the industry-leading provider of proprietary and innovative advanced small modular reactor ("SMR") nuclear technology, today announced results for the second quarter ended June 30, 2025.

"In May, NuScale was thrilled to receive Standard Design Approval from the NRC for our 77 MWe SMR design ahead of schedule, marking our second NRC design approval and enabling us to support a wider range of users," said John Hopkins, President and Chief Executive Officer of NuScale Power. "NuScale remains the only technology provider to obtain NRC design approval, positioning us well ahead of others in the market. With that distinction, as well as our partnership with ENTRA1 to commercialize our SMR technology inside ENTRA1 Energy Plants™, we are making strides toward deploying our technology. We look forward to providing safe, reliable, and sustainable energy technology for communities around the world."

Liquidity & Capital Resources

NuScale ended the second quarter with cash, cash equivalents, and short- and long-term investments of $489.9 million.

Comparison of the Three Months Ended June 30, 2025 and 2024

Revenue increased by $7.1 million to $8.1 million for the three months ended June 30, 2025, compared to $1.0 million for the three months ended June 30, 2024. Cost of sales increased by $5.4 million to $6.3 million for the three months ended June 30, 2025, compared to $0.9 million for the three months ended June 30, 2024. These increases were attributable to engineering and licensing fees, as well as services in support of RoPower's goal of deploying a power plant in Romania powered by six NuScale Power Modules™.

General and administrative expenses increased by $5.7 million to $22.5 million for the three months ended June 30, 2025, compared to $16.8 million for the three months ended June 30, 2024. This increase was primarily driven by higher business development costs associated with NuScale's transition from a research and development-based company to a commercial company, partially offset by cost optimization measures.

Other expenses decreased by $2.5 million to $10.5 million for the three months ended June 30, 2025, compared to $13.0 million for the three months ended June 30, 2024. This decrease was driven by cost optimization measures, partially offset by higher equity-based compensation costs.

Interest income increased by $3.8 million to $5.5 million for the three months ended June 30, 2025, compared to $1.7 million for the three months ended June 30, 2024. This was driven by an increase in NuScale's cash position which allowed management to invest more heavily in higher-yielding cash equivalents and investments.
