NuScale faces securities‑fraud suits after $495M ENTRA1 payment spurs 12.4% stock drop

Multiple securities‑fraud class action complaints and investor‑notification filings surfaced March 2–3, 2026 alleging NuScale Power Corporation misled investors about the experience of a partner, ENTRA1 Energy LLC, and that the revelations materially harmed shareholders. The notices, led by law firms including Bleichmar Fonti & Auld LLP and the Law Offices of Frank R. Cruz, set an April 20, 2026 lead plaintiff deadline and point to a November 6, 2025 disclosure that triggered the market reaction.

Plaintiffs allege that NuScale and certain officers made false or misleading statements and omitted material information about ENTRA1’s qualifications while entrusting the partner with commercialization, financing and initial operations of projects using NuScale Power Modules. The complaints and summaries cite a Nov. 6 earnings disclosure in which NuScale reported general and administrative expenses of $519 million for the quarter, up from $17 million a year earlier, driven largely by a $495 million payment to ENTRA1 under a TVA agreement. The company’s quarterly net loss rose to $532 million, from $46 million in the prior year.

“On November 6, 2025, NuScale surprised investors by revealing that the company’s general and administrative expenses had ballooned more than 3,000% to $519 million during its third fiscal quarter, up from $17 million in the prior year period, due largely to NuScale’s payment of $495 million to ENTRA1 for its TVA agreement. As a result, NuScale’s quarterly net loss skyrocketed to $532 million, up from $46 million in the prior year period. During a corresponding conference call, analysts pressed NuScale’s management regarding whether ENTRA1 was sufficiently experienced to own and operate the energy generation facilities contemplated by the TVA agreement. Additionally, NuScale's CEO disclosed that the agreement between ENTRA1 and TVA contemplated as many as 72 NPMs, meaning NuScale's ...” reads a complaint summary reproduced by one aggregator.

The filings contend ENTRA1 “had never built, financed, or operated any significant projects—let alone projects in the highly technical and complicated field of nuclear power generation—during its entire operating history,” and that NuScale had placed hundreds of millions of dollars of capital and commercialization responsibility in that partner despite those alleged gaps. The alleged misstatements cover the period May 13, 2025 through November 6, 2025, and plaintiffs point to a 12.4% decline in NuScale’s stock during November 7–10, 2025 as the market reaction supporting investor harm claims.

These are allegations in plaintiff filings and law‑firm notices; they are not judicial findings. Bleichmar Fonti & Auld’s press release includes the firm’s advertising disclaimer: “Attorney advertising. Past results do not guarantee future outcomes.” The notices republished by financial aggregators also urged investors who suffered losses to consider participating in lead‑plaintiff selection.

Beyond shareholder losses, the litigation raises broader questions for communities and policymakers about the governance and oversight of small modular reactor deployment. The ENTRA1–TVA agreement, if it proceeds, contemplated as many as 72 NuScale Power Modules, a scale that would affect regional planning, local labor markets and safety oversight. Allegations that a commercial partner lacked relevant project experience could complicate financing, delay construction timelines and erode public trust in communities that may host new nuclear facilities—outcomes with tangible social equity and public health implications.

The law‑firm notices and aggregator summaries do not include responses from NuScale or ENTRA1. The litigation is in early stages, with at least one federal case captioned Truedson v. NuScale Power Corporation, et al., Case No. 3:26‑cv‑00328 in the U.S. District Court for the District of Oregon noted in filings.
