Robbins LLP has filed a securities fraud class action lawsuit on behalf of investors who purchased NuScale Power Corporation (NYSE: SMR) Class A shares between May 13, 2025 and November 6, 2025. The lawsuit alleges that NuScale misled investors about the experience and capabilities of its commercialization partner, ENTRA1 Energy LLC, which had never built, financed, or operated any significant projects in the nuclear power generation field.

Why it matters

The lawsuit highlights concerns about NuScale's commercialization strategy and the risks it faced in entrusting its technology deployment to a partner with limited relevant experience. The significant financial losses suffered by investors as NuScale's stock price plummeted following the revelations about ENTRA1 underscore the importance of companies providing accurate and complete information to the market.

The details

According to the complaint, NuScale claimed that its partnership with ENTRA1 would allow the company to take its small modular nuclear reactor technology from development to deployment. However, the lawsuit alleges that during ENTRA1's entire operating history, it had never built, financed, or operated any significant project, let alone one in the nuclear power generation field. The complaint further alleges that NuScale failed to disclose these material facts to investors, exposing the company's commercialization strategy to significant undisclosed risks.

  • The class period runs from May 13, 2025 to November 6, 2025.
  • On November 6, 2025, NuScale revealed that its general and administrative expenses had ballooned more than 3,000% due largely to a $495 million payment to ENTRA1.
  • NuScale's stock price declined more than 12% over the following two trading days and continued to fall, reaching a low of $17 per share by November 21, 2025 - over 70% below the class period high.
