Investors with Substantial Losses Have Opportunity to Lead NuScale Power Class Action Lawsuit

Robbins Geller Rudman & Dowd LLP announces class action lawsuit against NuScale Power Corporation and its executives

Feb. 23, 2026 at 1:50pm

Robbins Geller Rudman & Dowd LLP has announced a class action lawsuit against NuScale Power Corporation (NYSE: SMR) and its executives, alleging violations of the Securities Exchange Act of 1934. The lawsuit covers purchasers of NuScale's Class A common stock between May 13, 2025 and November 6, 2025, and investors have until April 20, 2026 to seek appointment as lead plaintiff.

Why it matters

The lawsuit alleges that NuScale made false and misleading statements about its commercialization partner ENTRA1 Energy LLC, which lacked significant experience in the nuclear power generation field. This raises concerns about NuScale's ability to successfully deploy its technology and execute on its partnership with the Tennessee Valley Authority.

The details

The lawsuit claims that NuScale and its executives misled investors by falsely portraying ENTRA1 as an experienced partner capable of commercializing NuScale's small modular nuclear reactor technology. In reality, ENTRA1 had no prior experience owning, financing, or operating nuclear energy generation facilities. The lawsuit also alleges that NuScale's payments to ENTRA1 for the TVA agreement, totaling $495 million in Q3 2025, contributed to a massive increase in the company's general and administrative expenses and net losses.

  • The class period covers purchases of NuScale Class A common stock between May 13, 2025 and November 6, 2025.
  • Investors have until April 20, 2026 to seek appointment as lead plaintiff in the lawsuit.
