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 NuScale securities during the period from May 13, 2025 through November 6, 2025. The lawsuit alleges that NuScale misled investors about its commercialization and deployment strategy for its NuScale Power Module (NPM) technology, including touting ENTRA1 Energy LLC as an exclusive commercialization partner despite ENTRA1's lack of experience in nuclear power projects.

Why it matters

The lawsuit alleges that NuScale's misleading statements about its commercialization strategy and partnership with ENTRA1 Energy led to a significant drop in the company's stock price when the truth emerged. This case highlights the importance of transparency and accurate disclosures for publicly traded companies, especially those in the emerging nuclear energy technology sector.

The details

According to the lawsuit, NuScale revealed on November 6, 2025 that its third-quarter general and administrative expenses had surged to $519 million, largely due to a $495 million milestone payment to ENTRA1. The company also reported net losses of $532 million. During a conference call, CEO John L. Hopkins confirmed that milestone payments under an agreement with the Tennessee Valley Authority could potentially exceed $3 billion. Following these disclosures, NuScale's Class A shares dropped more than 12% over two trading sessions.

  • The class period is from May 13, 2025 through November 6, 2025.
  • The investor deadline to seek lead plaintiff status is April 20, 2026.
