A class action lawsuit alleging securities fraud has been filed against small modular reactor company NuScale Power. The legal challenge centers on claims that the firm failed to properly inform investors about the operational background of a key marketing partner. Affected shareholders have a deadline in April to join the case.
Shareholder Deadline and Market Impact
The significant legal uncertainty is having a pronounced effect on the company’s market valuation. Last Friday, NuScale’s stock closed at $11.67, marking a new 52-week low. This price represents a dramatic decline of approximately 78% from its peak in October 2025, highlighting a severe erosion of investor confidence.
For shareholders considering legal action, a critical date is approaching. Claims must be filed by April 20, 2026, for investors to seek lead plaintiff status in the proceedings. The court’s interpretation of whether NuScale’s disclosures during the relevant period were materially misleading will be pivotal to the case’s outcome. This lawsuit represents a significant test for the company’s past partnership and marketing strategies.
Should investors sell immediately? Or is it worth buying Nuscale Power?
Core Allegations: Partner Qualifications in Question
Filed in a U.S. District Court in Oregon, the suit pertains to investors who purchased the company’s shares between May and November 2025. The allegations focus specifically on NuScale’s collaboration with a partner identified as ENTRA1 Energy.
Plaintiffs contend that NuScale omitted or misrepresented crucial information regarding this partner’s qualifications. The company is accused of not disclosing that ENTRA1 Energy lacked any substantial experience in financing, owning, or operating nuclear power facilities. In the highly specialized and capital-intensive nuclear energy sector, the operational competence of strategic partners is a fundamental component for both the economic viability and the safety assurance of any project. The lawsuit suggests this alleged lack of transparency is a serious breach of disclosure obligations to the market.
