Portnoy Law Firm has initiated a class action lawsuit against NuScale Power Corporation on behalf of shareholders who purchased the company's securities between May 13, 2025 and November 6, 2025. The litigation alleges that NuScale made materially false statements regarding its commercialization partner ENTRA1's qualifications and experience in nuclear power generation, while allegedly failing to disclose associated risks to investors.
The lawsuit was prompted by NuScale's disclosure of a $495 million payment to ENTRA1 alongside a $532 million net loss for the quarter. Following the announcement, NuScale's stock price declined more than 12% over a two-day period. The filing claims investors were not adequately informed about the nature and extent of risks related to the partnership prior to these developments.
The class action represents a significant development for NuScale, which has been pursuing commercialization of small modular reactor technology. The lawsuit raises questions about the adequacy of disclosures surrounding strategic partnerships and their associated financial commitments. Investors who held NuScale securities during the specified period may be eligible to participate in the class action.
