A class action lawsuit was filed on behalf of investors who purchased NuScale Class A shares between May 13, 2025 and November 6, 2025. The complaint alleges NuScale misled investors about the capabilities and experience of its commercialization partner ENTRA1. It also alleges the company did not disclose risks tied to relying on ENTRA1 for commercialization, distribution, and deployment of its reactor modules. NuScale reported general and administrative expenses of USD 519 million for its third fiscal quarter, including a USD 495 million payment to ENTRA1 related to its TVA agreement. After the disclosure, NuScale shares fell more than 12% over two trading days, and later dropped to a low of USD 17 per share by November 21, 2025.
