The law firm of Robbins Geller Rudman & Dowd LLP has announced a securities class action lawsuit against NuScale Power Corporation (NYSE: SMR) and certain executives, alleging violations of the Securities Exchange Act of 1934. Investors who purchased NuScale Class A common stock between May 13, 2025 and November 6, 2025 have until April 20, 2026 to seek appointment as lead plaintiff in the lawsuit.

Why it matters

The lawsuit alleges that NuScale misled investors about the experience and qualifications of its exclusive commercialization partner, ENTRA1 Energy LLC, which lacked significant prior experience in the nuclear power generation industry. This exposed NuScale's commercialization strategy to material risks of failure, delays, and other setbacks.

The details

The lawsuit claims that NuScale and its executives made false and/or misleading statements about ENTRA1's capabilities, when in fact ENTRA1 had never built, financed, or operated any significant projects in the nuclear power field. NuScale's reliance on ENTRA1 as an exclusive partner appeared to be validated when ENTRA1 and the Tennessee Valley Authority (TVA) announced an agreement to develop power plants providing up to six gigawatts of new nuclear power. However, the lawsuit alleges this agreement exposed NuScale to over $3 billion in potential milestone payments to ENTRA1, an entity lacking the necessary experience.

  • 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.

What they’re saying

“During the corresponding conference call, analysts pressed NuScale management regarding whether ENTRA1 was sufficiently experienced to own and operate the energy generation facilities contemplated by the TVA agreement. NuScale's CEO, defendant John L. Hopkins, further revealed during the call that the agreement between ENTRA1 and TVA contemplated as many as 72 NPMs, meaning NuScale's milestone payments to ENTRA1 could potentially exceed more than $3 billion.”
