Robbins Geller Rudman & Dowd LLP has filed a class action lawsuit against NuScale Power Corporation (NYSE: SMR), alleging the company failed to disclose that it had entrusted its core NPM commercialization to an entity, ENTRA1 Energy LLC, that lacked significant prior experience in the highly technical field of nuclear power generation.

Why it matters

The lawsuit claims NuScale's reliance on ENTRA1 as an exclusive commercialization partner exposed the company to material risks of failure, delays, and other setbacks in bringing its small modular nuclear reactor technology to market. This could have significant implications for NuScale's growth and ability to execute on its partnership with the Tennessee Valley Authority.

The details

The lawsuit alleges that throughout the class period from May 13, 2025 to November 6, 2025, NuScale and its executives made false and/or misleading statements about ENTRA1's experience and qualifications, when in fact ENTRA1 had never built, financed, or operated any significant projects in the nuclear power generation field. The lawsuit further claims that NuScale's $495 million payment to ENTRA1 for the TVA agreement caused NuScale's general and administrative expenses to balloon over 3,000% in Q3 2025, leading to a $532 million quarterly net loss.

  • The class period runs from May 13, 2025 to November 6, 2025.
  • Investors have until April 20, 2026 to seek appointment as lead plaintiff.
