NuScale Power Faces Class Action Over Commercialization Partner Misrepresentation Claims

Securities litigation firm Kessler Topaz Meltzer & Check filed a class action in the U.S. District Court for the District of Oregon against NuScale Power Corporation (NYSE: SMR), alleging the company misled investors about the track record of its exclusive commercialization partner, ENTRA1 Energy LLC, during a six-month window when SMR shares climbed on a series of headline-grabbing partnership announcements.

The case, captioned Truedson v. NuScale Power Corporation, No. 3:26-cv-00328, covers statements made between May 13, 2025 and November 6, 2025. The complaint alleges NuScale failed to disclose that ENTRA1 had never built, financed, or operated any significant energy project during its entire operating history, let alone a project in the technically complex field of nuclear power generation. The complaint goes further, alleging that the experience and qualifications NuScale attributed to ENTRA1 actually belonged to principals of the Habboush Group, a separate entity with no meaningful nuclear track record.

The reckoning arrived on November 6, 2025, when NuScale's Q3 earnings revealed that general and administrative expenses had surged more than 3,000 percent to $519 million, up from $17 million in the same quarter a year earlier. The driver: a $495 million payment to ENTRA1 tied to the TVA Partnership Milestones Agreement, a deal NuScale had promoted as the largest SMR deployment program in U.S. history. The company's quarterly net loss ballooned to $532 million from $46 million. SMR shares fell $5.45, roughly 14.4 percent, in a single session.

That TVA agreement, announced September 2, 2025, called for ENTRA1 to develop and own six nuclear energy plants across TVA's seven-state territory, supplying up to 6 gigawatts of baseload power using NuScale Power Modules. The complaint alleges ENTRA1 held exclusive rights over commercialization, distribution, and deployment of NuScale's technology, and that the Partnership Milestones Agreement carried potential milestone payments exceeding $3 billion in total.

For SMR observers trying to read this lawsuit, the April 20 lead-plaintiff deadline is a procedural milestone, not a verdict. It marks the window for investors who suffered losses during the class period to petition the court to represent other shareholders. A court then appoints a lead plaintiff, typically the investor with the largest documented losses. From there, the case moves into briefing on motions to dismiss, and then potentially discovery. Most securities class actions settle; dismissal at the pleading stage is also common, particularly where forward-looking statements carried cautionary language.

Watch NuScale's 10-K and 10-Q filings for any revised disclosure language around ENTRA1's role, qualifications, and the structure of the Partnership Milestones Agreement. A material amendment to that deal, or disclosure of a replacement commercialization partner, would be a genuine signal rather than legal noise. Conversely, a motion to dismiss granted in NuScale's favor would remove a significant near-term overhang on project finance and offtake negotiations.

The case crystallizes a structural tension now facing every publicly traded advanced nuclear developer: the commercialization promises that attract capital are precisely the forward-looking statements that create litigation exposure when a partner's track record doesn't match the pitch.
