NuScale Power Corp (NYSE:SMR), a developer of small modular nuclear reactor technology, reported its fourth quarter and full-year 2025 financial results after the market close on Wednesday. The figures revealed a company still deep in its investment and commercialization phase, with financial performance falling short of analyst expectations and the stock trading lower in after-hours activity.
Earnings and Revenue Versus Estimates
The company's quarterly results significantly missed Wall Street's forecasts on both the top and bottom lines. For the fourth quarter of 2025, NuScale reported revenue of $1.81 million, a stark contrast to the analyst consensus estimate of $8.65 million. The earnings picture was similarly challenging, with the company posting a non-GAAP loss per share of $0.80, far wider than the estimated loss of $0.13 per share.
The full-year 2025 results underscore the scale of the company's current pre-revenue development status. NuScale reported annual revenue of $31.5 million, a decrease from $37.0 million in 2024. The net loss attributable to Class A common stockholders for the year was $355.8 million, or $2.17 per share, compared to a loss of $136.6 million, or $1.47 per share, in the prior year.
Key Financial Misses for Q4 2025:
- Revenue: Reported $1.81M vs. Estimate $8.65M
- EPS: Reported -$0.80 vs. Estimate -$0.13
Market Reaction
Investors reacted negatively to the earnings miss and the widening losses. In after-hours trading following the release, NuScale's stock declined approximately 3.8%. This extends a period of weakness for the shares, which are down roughly 35% over the past month. The immediate market reaction reflects disappointment with the pace of revenue generation and the substantial ongoing costs associated with bringing its first-of-a-kind technology to market.
Press Release Highlights and Strategic Focus
Beyond the raw financial numbers, the earnings press release emphasized operational and strategic milestones, framing 2025 as a "breakthrough year." President and CEO John Hopkins highlighted the company's position as the only SMR technology with U.S. Nuclear Regulatory Commission design approval for its uprated 77 MWe module.
The most significant announcements centered on commercialization progress:
- A non-binding agreement was announced between NuScale's partner ENTRA1 and the Tennessee Valley Authority (TVA) to explore deploying up to 6 gigawatts of NuScale SMR capacity.
- The company released a study validating the use of its reactors for industrial process heat applications, potentially opening a new market.
- Management stated its primary 2026 focus will be on technology commercialization and readiness for manufacturing its first Power Module.
Financially, the company bolstered its balance sheet significantly. NuScale ended the year with $1.3 billion in cash, cash equivalents, and investments, up from $447 million at the end of 2024. This increase was primarily due to raising $750 million in gross proceeds through an at-the-market (ATM) equity offering in the fourth quarter. This war chest is intended to fund the lengthy and capital-intensive path to first revenue from reactor sales.
Looking Ahead: Analyst Estimates for 2026
With the company in a development stage, analyst estimates for the coming year project continued losses as spending likely remains high. For the full year 2026, the current consensus estimates a loss per share of approximately $0.78 on sales of around $133.9 million. For the upcoming first quarter of 2026, analysts are forecasting a loss of about $0.13 per share on revenue of $24.3 million. The company did not provide formal financial guidance in its release to compare against these projections.
Conclusion
NuScale Power's latest earnings report paints a clear picture of a company at a critical juncture. While it has achieved important regulatory and partnership milestones that solidify its "first mover" status in the advanced nuclear arena, the financials reflect the immense cost and time required to translate technology into commercial sales. The significant miss on quarterly estimates and the sharp increase in annual net loss—driven largely by a $507.4 million milestone payment to partner ENTRA1—appear to have dampened investor enthusiasm in the near term. The market's reaction suggests that patience is being tested, and attention will now turn to the company's ability to convert its strong liquidity position and strategic agreements into tangible revenue contracts in the year ahead.
