The law firm of Robbins Geller Rudman & Dowd LLP has filed a class action lawsuit against NuScale Power Corporation (NYSE: SMR) on behalf of investors who purchased NuScale Class A common stock between May 13, 2025 and November 6, 2025. The lawsuit alleges that NuScale and its executives made false and misleading statements about its commercialization partner ENTRA1 Energy LLC, which lacked significant experience in the nuclear power industry.

Why it matters

This lawsuit highlights the risks investors face when companies make exaggerated claims about their business partnerships and growth prospects. The allegations raise concerns about NuScale's ability to successfully commercialize its small modular nuclear reactor technology and the due diligence it conducted on its key commercialization partner.

The details

The lawsuit alleges that NuScale claimed ENTRA1 would allow it to take its nuclear reactor technology from development to deployment, but ENTRA1 had never built, financed, or operated any significant projects in the nuclear power industry. The lawsuit further alleges that NuScale's payments to ENTRA1 for a deal with the Tennessee Valley Authority ballooned its general and administrative expenses by over 3,000% in Q3 2025, leading to a massive $532 million quarterly net loss.

  • 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.
