NuScale Power's Epic Decline: The $57 Collapse and What's Driving It

NuScale Power (NYSE: SMR), once the darling of the nuclear energy sector, experienced a stunning reversal in early 2026. The small modular reactor (SMR) developer’s stock, which peaked at $57.42 on October 16, 2025, has since cratered to approximately $13—representing a gut-wrenching 77% loss for investors who bought at the all-time high. Market analysts, including perspectives from industry observers, are now wrestling with a critical question: Is this a buying opportunity or a warning signal?

Several factors converged to trigger this sharp downturn. The first major headwind arrived in October 2025, when widespread concerns about an artificial intelligence bubble gripped Wall Street. Since NuScale positioned itself as a power solution for AI-hungry data centers through its SMR technology, the pessimism surrounding AI’s profit potential directly hammered the nuclear energy company. Comparable players like Oklo and Nano Nuclear Energy experienced similar sell-offs during the same sentiment shift.

The Earnings Shock and Share Dilution Blow

The damage intensified in November when NuScale released third-quarter financial results that missed Wall Street’s expectations by a substantial margin. Analysts had penciled in an earnings-per-share loss of $0.11, but the company instead reported a staggering $1.85 loss per share. The misfire spooked already-nervous investors.

Things got worse in December. NuScale received shareholder authorization to double its outstanding shares from 332 million to 662 million—a classic dilution warning that typically pressures stock valuations. Then came the knockout punch: Fluor, one of NuScale’s largest institutional supporters and a strategic partner, announced plans to completely exit its position in the company. The cumulative bad news created a perfect storm of negative sentiment.

A Glimmer of Hope: The Romanian Connection

Despite the relentless headwinds, not everything points downward. A potentially transformational development emerged in February 2026 when shareholders of Romanian nuclear operator Nuclearelectrica approved a Final Investment Decision to construct an SMR facility using NuScale’s technology. The project, designed to deploy six 77-megawatt modules, is targeting commercial operation by 2033.

This represents NuScale’s first concrete pathway toward generating meaningful revenue. However, as market observers point out, asking investors to wait seven years for commercialization presents a significant challenge—especially when the company continues burning cash and reporting substantial losses. For a speculative play with execution risk and timeline uncertainty, patience is a luxury many shareholders simply cannot afford.

The Investment Dilemma: Risk Versus Opportunity

NuScale remains a quintessential speculative stock, best suited for investors with a demonstrated tolerance for extreme volatility and multi-year holding periods. The company still needs to secure additional firm contracts to validate its business model and shore up investor confidence. Conservative investors seeking nuclear energy exposure would likely find better shelter through nuclear-focused exchange-traded funds (ETFs), which offer diversification without single-company concentration risk.

The path forward hinges entirely on execution. If NuScale can convert the Romanian project into a revenue stream and attract additional customers for its modular reactor technology, the current stock price could ultimately represent an attractive entry point. Conversely, if project delays, cost overruns, or competitive pressures mount, further disappointment awaits shareholders. For now, the small modular reactor pioneer sits at a crossroads—with 2026 shaping up as a critical year for validating its turnaround narrative.
