Philadelphia, Pennsylvania--(Newsfile Corp. - February 24, 2026) - National plaintiffs' law firm Berger Montague PC announces that a class action lawsuit has been filed against NuScale Power Corporation (NYSE: SMR) ("NuScale" or the "Company") on behalf of investors who purchased or otherwise acquired NuScale securities during the period from May 13, 2025 through November 6, 2025 (the "Class Period").

Investor Deadline: Investors who purchased NuScale securities during the Class Period may, no later than April 20, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.

Headquartered in Corvallis, Oregon, NuScale designs and deploys small modular nuclear reactors, providing innovative nuclear energy solutions globally.

The Complaint alleges that NuScale misled investors regarding its commercialization and deployment strategy for its NuScale Power Module ("NPM") technology. Defendants allegedly touted ENTRA1 Energy LLC as an exclusive commercialization partner for NPMs, despite the fact that ENTRA1 had no prior experience owning, financing, or operating nuclear power projects.

According to the lawsuit, the truth emerged on November 6, 2025, when NuScale revealed that third-quarter general and administrative expenses had surged to $519 million for the quarter - more than 3,000% higher than the prior year period - largely due to a $495 million milestone payment to ENTRA1, and that net losses had risen to $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 Class A shares dropped more than 12% over two trading sessions, from a closing price of $32.46 per share on November 6, 2025 to a close of $28.43 per share on November 10.
