National plaintiffs' law firm Berger Montague PC has filed a class action lawsuit against NuScale Power Corporation (NYSE: SMR) 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, and its commercialization strategy.

Why it matters

The lawsuit claims that NuScale's commercialization strategy was exposed to undisclosed risks of failure, delays, regulatory challenges, and other setbacks. The revelation of these issues on November 6, 2025 caused NuScale's stock price to decline more than 12% over the following two trading days.

The details

The lawsuit alleges that during the Class Period, NuScale made false and/or misleading statements and/or failed to disclose that: (i) NuScale's exclusive commercialization partner, ENTRA1 Energy LLC, had no meaningful experience in owning, financing, or operating nuclear power projects; (ii) the purported experience and qualifications attributed to ENTRA1 actually referred to principals of the Habboush Group, a distinct entity without significant nuclear energy experience; and (iii) NuScale's commercialization strategy was exposed to undisclosed risks of failure, delays, regulatory challenges, and other setbacks.

  • The Class Period is from May 13, 2025 through November 6, 2025.
  • The investor deadline to inquire about joining the lawsuit is April 20, 2026.
