Company overview

Company snapshot

• Centrus Energy supplies low-enriched uranium (LEU), separative work units (SWU), and technical solutions for the nuclear power industry, including engineering and manufacturing services.
• The firm generates revenue through the sale of nuclear fuel components and technical consulting, with business segments focused on LEU sales and specialized technical services.
• It serves utilities operating nuclear power plants, as well as public and private sector clients in the United States, Japan, Belgium, and international markets.

Centrus Energy is a specialized supplier of nuclear fuel and related technical services, leveraging expertise in uranium enrichment and engineering solutions for the global nuclear power sector. The company’s dual-segment structure enables it to capture value from both commodity fuel sales and higher-margin technical services. With a focus on serving regulated utilities and government entities, Centrus Energy maintains a strategic position in the nuclear supply chain, supported by a track record of technical innovation and operational reliability.

What this transaction means for investors

With demand for nuclear power increasingly tied to electrification and even AI data center growth, the strategic importance of a firm like Centrus has risen sharply, and recent results highlight steady progress. Centrus reported full-year revenue of $448.7 million in 2025, up from $442 million one year earlier, with net income of $77.8 million as margins improved across its enrichment business. Among highlights, the Department of Energy selected the firm for a $900 million high-assay low-enriched uranium (HALEU) award, subject to negotiations. And perhaps more importantly, the company now carries roughly $3.8 billion in backlog extending as far as 2040, providing over a decade of visibility.

More broadly, Granahan Investment Management’s largest holdings tilt toward software, infrastructure, and industrial technology names rather than commodity-exposed energy companies, but that doesn’t necessarily reflect any souring on the space. With recent highs being tested last quarter, as shares tumbled about 40% between October and the end of the year, trimming the position after a massive run may simply reflect portfolio discipline amid a volatile stretch.
