X-energy, Centrus Sign HALEU Supply Agreement for Xe-100 Advanced Small Modular Reactor Development

* Definitive Agreement for Long-Term Supply of High-Assay, Low-Enriched Uranium (“HALEU”) * Advances Commercialization for HALEU Enrichment and TRISO Fuel Fabrication ROCKVILLE, Md., Aug. 06, 2026 (GLOBE NEWSWIRE) -- X-Energy, Inc. (Nasdaq: XE) (“X-energy” or “the Company”), a leading developer of advanced nuclear reactors and fuel technology, and Centrus Energy Corp. (NYSE: LEU) (“Centrus”), a trusted supplier of nuclear fuel, services and technology, today announced a definitive agreement for Centrus to provide X-energy with enrichment services for Low-Enriched Uranium (“LEU”) and High-Assay Low-Enriched Uranium (“HALEU”). At full execution, the agreement meaningfully de-risks X-energy's Xe-100 project pipeline and would secure HALEU to support a portion of the initial fuel needs of X-energy’s 11.5 GW commercial pipeline.

The partnership combines the capabilities of the first two U.S. Nuclear Regulatory Commission-licensed HALEU fuel facilities in U.S. history, advancing commercialization of next-generation nuclear fuels across concurrent segments of the domestic fuel cycle. HALEU enriched by Centrus at the American Centrifuge Plant in Piketon, Ohio will be supplied to X-energy's fuel subsidiary TRISO-X, LLC (“TRISO-X”) for the fabrication of TRISO-X coated particle fuel at its fuel fabrication campus in Oak Ridge, Tennessee.
