NuScale Power Corporation experienced a sharp decline on Tuesday, with shares falling 7.2% to close at $10.00. The stock traded in a wide range between $9.595 and $11.08 before settling, as heavy volume of 38.9 million shares reflected heightened investor anxiety. The selloff was part of a broader market downturn, with the Nasdaq Composite dropping 0.97% and the S&P 500 slipping 0.26%, driven by renewed selling in technology stocks.
The decline in NuScale shares underscores the vulnerability of speculative nuclear energy plays to shifts in market sentiment. The company, a prominent player in the small modular reactor (SMR) space, has seen its stock become a bellwether for investor interest in nuclear power as a solution for the energy demands of artificial intelligence data centers. However, Tuesday's move suggests that optimism about the nuclear-AI trade is waning amid broader risk aversion.
Peers Mixed Amid Sector Volatility
The nuclear sector showed mixed performance on Tuesday. Oklo Inc. fell approximately 4.2%, while Nano Nuclear Energy dropped 7.4%. In contrast, BWX Technologies, a supplier to nuclear and defense markets, gained 0.7%. The divergent moves highlight the uneven nature of the nuclear trade, where companies with more established contracts and revenues fare better than those still in the development phase.
Revenue Challenges and Contract Uncertainty
NuScale's first-quarter financial results reveal the gap between its ambitions and its current performance. Revenue for the quarter was just $565,000, a steep decline from $13.4 million in the same period last year. The company attributed the drop to the absence of licensing and engineering work that had boosted results in early 2025. Net loss for the quarter stood at $46.7 million. Despite these challenges, CEO John Hopkins emphasized in May that “demand for reliable, carbon-free power has never been greater.”
The company ended the first quarter with $1.0 billion in liquidity and capital resources. However, it also established a $1 billion at-the-market (ATM) program, which allows it to issue additional shares as needed. In the first quarter, NuScale sold 3.16 million shares for $37.3 million, and after March 31, it sold another 22.36 million shares for $213.5 million, according to a regulatory filing. The ATM program could exert downward pressure on the stock if the company continues to dilute shareholders.
Growth Prospects Hinge on Binding Contracts
NuScale's future growth story centers on expanding its footprint in the U.S. and Europe. The company has a non-binding agreement with ENTRA1 and the Tennessee Valley Authority to develop up to 6 gigawatts of new nuclear capacity, contingent on securing power purchase agreements. In Romania, a proposed 460-megawatt NuScale-based plant is estimated to cost between $6 billion and $7 billion, though funding remains unresolved. The company's primary competitive advantage lies in regulatory approval: the U.S. Nuclear Regulatory Commission certified its 77-megawatt reactor design in 2025, following earlier approval of a 50-megawatt model. Hopkins has described the technology as “near-term deployable,” but noted that construction timing depends on customers.
Despite these milestones, NuScale faces significant risks. The company has warned investors that results may fall short if it cannot secure binding module contracts, if manufacturing or construction is delayed, if partners struggle with financing, or if its module power proves uncompetitive on price. These uncertainties were at the forefront of investor concerns on Tuesday.
Market Outlook: Stock Reacts to Milestones, Not Revenue
In the current environment, NuScale's stock price is driven less by quarterly revenue and more by progress toward key milestones: signing a paying customer, securing a power agreement, or demonstrating the ability to move from regulatory approval to actual construction. Without these proof points, the stock remains vulnerable to the same pressures affecting other companies reliant on future cash flows—a softer Nasdaq, rising funding costs, and investors losing patience with promises that may not materialize until the 2030s.
