NuScale Power Corporation faces a securities fraud class action lawsuit in the U.S. District Court for the District of Oregon (Case No. 3:26-cv-00328) over alleged misrepresentations about ENTRA1 Energy LLC’s experience and qualifications in managing a critical $495 million Tennessee Valley Authority agreement.
The lawsuit alleges that NuScale made false and misleading statements to investors about ENTRA1’s capabilities—despite the company being a 3-year-old entity that has never built, financed, or operated any nuclear power project. On November 6, 2025, when NuScale disclosed massive, previously undisclosed expenses and losses, the stock price collapsed by 14.4% in a single trading day, with broader declines exceeding 70% over subsequent weeks.

What Is the NuScale Securities Fraud Case About?
The NuScale securities fraud lawsuit centers on a fundamental mismatch between what the company told investors and what was true about its business partner. NuScale allegedly made false and misleading statements regarding ENTRA1 Energy LLC’s experience, qualifications, and ability to execute a major contract with the Tennessee Valley Authority. The complaint alleges that NuScale did not disclose—or actively concealed—the fact that ENTRA1 is a newly formed company with no track record in building, financing, or operating nuclear power facilities.
For context, this is similar to a commercial construction company entrusting a billion-dollar project to a startup contractor without disclosing that the contractor has never completed a major project. The lawsuit covers a class period from May 13, 2025, through November 6, 2025. This period encompasses the time when NuScale was publicly making statements about its strategic partnership with ENTRA1 while allegedly omitting material facts about ENTRA1’s inexperience and the associated risks to the company’s business plan.
The ENTRA1 Controversy and Undisclosed Risk
According to a Guggenheim securities analysis referenced in court filings, ENTRA1 “has never built, financed or operated anything.” This assessment underscores the core breach of disclosure—NuScale entrusted $495 million in capital and the execution of a major TVA agreement to a company with zero operational history in the nuclear power sector. For investors relying on NuScale’s representations, this revelation represents a critical gap between the risk profile they believed they were exposed to and the actual risk.
The lack of disclosure regarding ENTRA1’s inexperience in nuclear power—an industry with stringent regulatory, technical, and operational requirements—is particularly significant. Unlike industries where new entrants can more easily participate, nuclear power requires specialized expertise, regulatory approval, and a demonstrated track record. By not disclosing ENTRA1’s lack of nuclear experience, NuScale allegedly misled investors about the viability of its commercial strategy and the safety of capital being deployed.
The Financial Red Flags and Stock Collapse
The financial impact of this case is stark and immediate. On November 5, 2025, NuScale’s stock closed at $37.91 per share. The very next day, November 6, 2025, when the company disclosed quarterly results and information about ENTRA1, the stock dropped to $32.46—a loss of $5.45 per share, or 14.4%, in a single trading session.
This sudden decline is typical of class action securities fraud cases, where material misstatements suddenly come to light and shareholders realize they have been harmed. More broadly, the stock price had climbed above $57 during the class period but fell to $17 by November 10, 2025—representing a total decline of over 70% in less than a week. What triggered this collapse was the November 6, 2025 disclosure of Q3 2025 financial results showing a net loss of $532 million and, most alarmingly, general and administrative (G&A) expenses of $519 million, compared to just $17 million in the prior year. This represents a 3,000%+ increase in G&A expenses—a red flag that investors claim should have been disclosed earlier and more transparently regarding its connection to the ENTRA1 arrangement.
Who Are the Named Defendants?
The lawsuit names both NuScale Power Corporation and two individual officers with personal liability: John L. Hopkins, who has served as Chief Executive Officer since December 2012, and Robert Ramsey Hamady, who became Chief Financial Officer in August 2023. The complaint also identifies Fluor Corporation as an entity allegedly involved in the matter.
John Hopkins’ long tenure at NuScale (over 13 years as CEO) means he was in a position to know about ENTRA1’s background and capabilities; similarly, Robert Hamady, as CFO, would have visibility into the financial commitments and the due diligence (or lack thereof) underlying the ENTRA1 partnership. When executives are named personally in securities fraud cases, it signals that plaintiffs believe the individuals had knowledge of the misstatements or recklessly disregarded red flags. CFOs in particular are held to a high standard regarding financial disclosures and material risks to the company’s financial condition.
The Legal Claims and Securities Law Violations
The lawsuit asserts multiple violations of federal securities law. Specifically, the complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as well as violations of SEC Rule 10b-5. These provisions make it unlawful to make untrue statements of material fact or to omit material facts necessary to make statements not misleading, in connection with the purchase or sale of securities.
A material fact is one that a reasonable investor would consider important in deciding whether to buy, hold, or sell a security. The ENTRA1 partnership—involving $495 million in capital and serving as a cornerstone of NuScale’s commercialization strategy—clearly qualifies. By failing to disclose ENTRA1’s lack of nuclear power experience and operational track record, NuScale’s executives allegedly violated these fundamental securities law provisions.
Important Deadlines for Investors
The lead plaintiff filing deadline for this lawsuit is April 20, 2026. This deadline is critical for any investor who purchased NuScale stock during the class period (May 13, 2025 – November 6, 2025) and incurred losses. To qualify as a lead plaintiff, an investor typically must have purchased a significant amount of stock and be willing to serve in a representative capacity.
Missing this deadline can affect an investor’s ability to participate in the case or receive recovery. Investors should gather documentation of their purchases and losses during the class period and consult with an attorney who specializes in securities litigation to understand their options and whether they may qualify as a lead plaintiff. Even if an investor does not become the lead plaintiff, they may still be part of the class and eligible for recovery.
Broader Implications for Small Modular Reactor (SMR) Industry
NuScale’s case carries implications beyond the company itself. NuScale is one of the leading developers of Small Modular Reactors (SMRs), which have been touted as a potential clean energy solution. The financial and reputational damage from this lawsuit may impact not only NuScale’s ability to secure financing and partnerships but also investor confidence in the broader SMR industry.
When a major player in an emerging sector faces fraud allegations, it can dampen investment and regulatory enthusiasm across the industry. However, it is important to note that securities fraud claims against one company do not invalidate the technology or commercial potential of SMRs generally. Rather, this case highlights the critical importance of transparent due diligence and honest disclosure when companies partner with newer or less-established entities to execute major contracts.
