Investors who purchased NuScale Power Corporation (NYSE: SMR) Class A common stock between May 13, 2025 and November 6, 2025 have until April 20, 2026 to seek appointment as lead plaintiff in a class action lawsuit against NuScale, its top executives, and Fluor Corporation. The lawsuit alleges the defendants made false and misleading statements about NuScale's commercialization partnership with ENTRA1 Energy LLC, which lacked significant experience in the nuclear power industry.

Why it matters

The lawsuit alleges that NuScale's reliance on ENTRA1, an entity with no prior experience in nuclear power generation, exposed the company to significant undisclosed risks in its commercialization strategy. The revelations about NuScale's ballooning expenses and payments to ENTRA1 caused a significant drop in the company's stock price, impacting investors.

The details

The class action lawsuit, captioned Truedson v. NuScale Power Corporation, alleges that NuScale, its top executives, and Fluor Corporation violated the Securities Exchange Act of 1934. Prior to the class period, NuScale had claimed its partnership with ENTRA1 would allow it to take its small modular nuclear reactor technology from development to deployment. However, the lawsuit alleges that ENTRA1 had no significant prior experience in owning, financing, or operating nuclear energy generation facilities, contrary to NuScale's representations. On November 6, 2025, NuScale revealed that its general and administrative expenses had ballooned more than 3,000% due largely to payments to ENTRA1 for its agreement with the Tennessee Valley Authority, causing a significant drop in NuScale's stock price.

  • The class period is from May 13, 2025 to November 6, 2025, both dates inclusive.
  • Investors have until April 20, 2026 to seek appointment as lead plaintiff in the class action lawsuit.
