A securities fraud class action lawsuit has been filed against NuScale Power Corporation (NYSE: SMR) on behalf of those who purchased or acquired NuScale Class A common stock between May 13, 2025, and November 6, 2025. The lawsuit alleges that NuScale made false and/or misleading statements and/or failed to disclose material information about its commercialization strategy and the experience of its partner, ENTRA1 Energy LLC.

Why it matters

The lawsuit alleges that NuScale entrusted its commercialization, distribution, and deployment of its nuclear power technology to an entity that lacked significant prior experience in the field, exposing the company to material risks of failure, delays, and other negative setbacks.

The details

The complaint alleges that throughout the Class Period, NuScale made false and/or misleading statements and/or failed to disclose that: (1) ENTRA1 Energy LLC had never built, financed, or operated any significant projects in the highly technical and complicated field of nuclear power generation; (2) NuScale had entrusted its commercialization, distribution, and deployment of its NuScale Power Module and hundreds of millions of dollars of NuScale capital to an entity that lacked any significant prior experience owning, financing, or operating nuclear energy generation facilities; and (3) the purported experience and qualifications attributed to ENTRA1 by NuScale in fact referred to the purported experience and qualifications of the principals of the Habboush Group, a distinct entity without significant experience in the field of nuclear power generation.

  • The Class Period is from May 13, 2025, through November 6, 2025.
  • The deadline for investors to file for lead plaintiff status is April 20, 2026.
