Fluor Corporation has significantly reduced its investment in NuScale Power Corporation, selling a substantial block of shares valued at approximately $150 million. According to a filing with the Securities and Exchange Commission, Fluor transferred 12.9 million shares of NuScale's Class A stock to Citibank, N.A. at a price of $11.6293 per share on April 15, 2026.
The transaction lowers Fluor's reported ownership in the advanced nuclear reactor company to 13.5 million shares, representing a 3.9% stake in the combined Class A and Class B stock. This move pushes Fluor's holding below the 5% threshold, which relieves the engineering and construction firm from future Schedule 13D disclosure requirements related to its NuScale position.
Despite the sizable divestment by a long-term strategic partner, NuScale's stock experienced a notable rally. Shares closed at $12.65 on Friday, April 18, 2026, marking a gain of roughly 10.8%. Trading volume was exceptionally heavy, with nearly 67.1 million shares changing hands, indicating strong investor interest.
This sale is part of Fluor's ongoing strategy to monetize its investment in NuScale. In February, the company informed investors it had already realized $1.35 billion from selling 71 million NuScale shares and was working to exit its remaining 40 million shares, a process it expects to complete during the second quarter of 2026. The latest transaction stems from an agreement established in November between Fluor and NuScale to convert and sell Fluor's final stake.
NuScale specializes in small modular reactor (SMR) technology. Its NuScale Power Module is designed to generate 77 megawatts of electricity, with the capability to combine up to twelve modules for a total output of 924 megawatts. The company achieved a significant regulatory milestone in May 2025 when the U.S. Nuclear Regulatory Commission approved its 77-megawatt reactor design.
The broader advanced nuclear sector saw mixed activity. Shares of developer Oklo finished Friday's session up approximately 4.0%, while Nano Nuclear Energy advanced around 5.5%. The sector remains in focus as traders weigh rising global power demand against persistent concerns over project financing, construction delays, and potential equity dilution.
For NuScale, the path forward hinges on securing firm customer commitments and arranging project financing at costs acceptable to utilities and large industrial customers. The company faced a setback in 2023 when a flagship U.S. SMR project with a Utah municipal power group was canceled due to escalating costs, despite having secured federal funding.
NuScale is scheduled to provide its next business update on May 7, 2026, after the market closes. The first-quarter 2026 earnings call will offer investors fresh details on the company's cash position, recent commercial developments, and the status of its project pipeline following Fluor's reduced involvement.
