National plaintiffs' law firm Berger Montague PC has announced a class action lawsuit against NuScale Power Corporation on behalf of investors who purchased or acquired NuScale securities during the period from May 13, 2025 through November 6, 2025. The lawsuit alleges that NuScale made false and/or misleading statements about its exclusive commercialization partner ENTRA1 Energy LLC, which had no meaningful experience in owning, financing, or operating nuclear power projects.

Why it matters

The lawsuit highlights concerns about NuScale's commercialization strategy and the risks it faced in terms of potential failures, delays, regulatory challenges, and other setbacks. The significant surge in NuScale's general and administrative expenses and net loss in the third fiscal quarter of 2025 further underscores the issues the company was facing.

The details

The lawsuit alleges that during the Class Period, NuScale made false and/or misleading statements about its exclusive commercialization partner ENTRA1 Energy LLC, claiming it had experience in owning, financing, and operating nuclear power projects, when in fact the purported experience and qualifications attributed to ENTRA1 actually referred to principals of the Habboush Group, a distinct entity without significant nuclear energy experience. The truth was revealed on November 6, 2025, when NuScale disclosed that its general and administrative expenses had surged more than 3,000% to $519 million for the third fiscal quarter, primarily due to a $495 million payment to ENTRA1 under an agreement with the Tennessee Valley Authority, and that its net loss skyrocketed to $532 million for the quarter.

  • The class action lawsuit was filed on behalf of investors who purchased or acquired NuScale securities during the period from May 13, 2025 through November 6, 2025.
  • Investors who purchased NuScale securities during the Class Period may, no later than April 20, 2026, seek to be appointed as a lead plaintiff representative of the class.
