NuScale Power: Cash Burn Threatens Timeline for SMR Stock

NuScale Power's stock has climbed this year on expectations that small modular reactors will drive a nuclear revival. The company reported $9 million in first-quarter revenue, mostly from Department of Energy cost-sharing agreements. Its quarterly cash burn has averaged $85 million over the past year, according to its latest SEC filing. At that rate, NuScale has roughly 18 months of runway without additional funding. No utility has signed a binding power purchase agreement for its first commercial reactor project in Idaho.

The lead project depends on a firm order from the Utah Associated Municipal Power Systems, a group that already scaled back its initial commitment. NuScale's design won NRC approval in 2023. A final design certification is still pending. That certification is due in the third quarter of 2026. If it slips, NuScale may need to revise its project schedule again. The company has already delayed expected commercialization from 2029 to 2030 in earlier updates.

The 2023 NRC approval was a safety review. The final design certification is a separate step that allows utilities to reference the design in their license applications. Without it, project financing remains theoretical.

The cash runway is sensitive to any timeline extension. If the NRC decision slips by six months, the runway shrinks to about 12 months. A one-year delay would force NuScale to raise capital before construction begins. The company completed a $50 million at-the-market equity offering in 2025. Another round would dilute existing holders.

A Seeking Alpha contributor who is long SMR argued the nuclear renaissance theme will play out over years. The contributor's disclosure shows a beneficial long position in the stock. NuScale's own filings sketch a tighter road. The company has limited revenue and a project timeline that has slipped before. The contributor's thesis focused on long-term potential without addressing near-term liquidity constraints.

Rival developers are moving faster. TerraPower, backed by Bill Gates and the Department of Energy, received a $2 billion cost-share award for its Natrium demonstration plant in Wyoming. Construction is expected to start before NuScale's first project breaks ground. X-energy raised $500 million in Series C financing in 2025 led by existing backers. Both companies have pursued different reactor designs and regulatory paths. Each could claim first-mover status if NuScale's timeline slips further.

The next concrete marker is the NRC's final design approval, expected in the third quarter of 2026. That date will determine whether NuScale can hold its project timeline or needs another revision. The company's own filings acknowledge that construction start depends on that milestone.

What would reduce the risk is a signed power purchase agreement with any utility, ideally backed by a DOE loan guarantee or an Inflation Reduction Act tax-credit commitment. What would worsen it is a prolonged NRC review or a competitor winning a binding contract first. Until then, the cash burn continues without a new PPA. The third-quarter NRC decision will determine whether the project timeline holds or slips again.
