NuScale Power's stock plummeted 5.02% during intraday trading on Thursday, following news of legal challenges facing the company.
The sharp decline comes as a securities class action lawsuit has been filed against NuScale Power Corp. and certain senior executives in U.S. District Court for the District of Oregon. The lawsuit alleges securities fraud tied to statements about partner ENTRA1's experience and role in commercializing NuScale's nuclear power modules.
The legal action follows a November 2025 disclosure of a $495 million payment to ENTRA1 and subsequent analyst scrutiny, which previously caused NuScale shares to fall about 12.4% over two trading days. The lawsuit claims the company made misleading statements and omissions about ENTRA1's experience and related risks to NuScale's commercialization strategy.
