NuScale Power Faces Mounting Legal Pressure and Financial Strain

NuScale Power confronts securities fraud lawsuits and a massive Q4 loss after costs surged over 3000%, driven by a $495M partner payment. Shares hit a 52-week low.

NuScale Power Corporation finds itself navigating a perfect storm of legal challenges and disappointing financial results. The company, a developer of modular nuclear reactor technology, is confronting multiple class-action lawsuits alleging securities fraud. These legal actions center on NuScale's commercial partnership with ENTRA1 Energy, with plaintiffs claiming investors were misled about the partner's nuclear sector experience and associated risks.

Financial Performance Misses the Mark

The company's recent fourth-quarter 2025 earnings report failed to reassure the market. NuScale posted a significant loss per share of $0.80, starkly missing analyst expectations for a $0.10 loss. Revenue also came in well below forecasts, reaching only $1.81 million against projections of $8.76 million. This underwhelming performance has prompted several prominent financial institutions, including Goldman Sachs, Citigroup, and UBS, to revise their price targets downward. Reports also indicate that major shareholder Fluor has reduced its stake in the company.

Soaring Costs Trigger Legal Scrutiny

The catalyst for the current legal predicament emerged from a November 2025 disclosure. NuScale reported a dramatic surge in its general and administrative expenses, which ballooned to $519 million. This figure represents an increase of over 3,000% compared to the previous year. A substantial payment of $495 million to partner ENTRA1 accounted for the bulk of this cost explosion. Consequently, the quarterly loss widened to $532 million, severely shaking investor confidence.

The stock's performance reflects this growing uncertainty. Shares closed at $10.30 on Friday, marking a new 52-week low. This price represents a staggering decline of approximately 80% from the stock's peak above $53 in October 2025. In the latest trading session alone, the share price fell a further 6.28%.

Operational and Financial Hurdles Persist

Amid these challenges, NuScale continues to point to the ongoing certification process for its small modular reactor designs by the U.S. Nuclear Regulatory Commission. However, investor attention has shifted decisively toward the company's financial stability. High cash-burn rates and the potential for shareholder dilution from a planned increase in authorized shares are adding to the negative sentiment.

Investors affected by the alleged securities fraud have until April 20, 2026, to file as lead plaintiffs in the class-action proceedings. For the coming months, the twin issues of legally dissecting the ENTRA1 partnership and stabilizing the company's balance sheet are set to dominate the narrative for NuScale Power.
