ROCKVILLE, Md., Aug. 03, 2026 (GLOBE NEWSWIRE) -- X-Energy, Inc. (Nasdaq: XE) ("X-energy" or "the Company"), a leading developer of advanced nuclear reactors and fuel technology, and SGL Carbon ("SGL") today announced a binding agreement to double SGL's production capacity for medium-grain isotropic graphite ("NBG-18"), a specialized material central to X-energy's Xe-100 high-temperature gas-cooled reactor ("HTGR"). X-energy and SGL's (together, the "Companies") agreement would expand the supply chain for a critical long-lead material, supporting execution of X-energy's 11+ GW commercial pipeline. Under the agreement, X-energy will invest up to $8 million in milestone-based payments to support new facilities and equipment upgrades at SGL's site in Chedde, France , enabling the facility to produce graphite billets for up to 8 new Xe-100 reactors per year. SGL has concurrently agreed to expand U.S. capacity for machining of billets into graphite blocks, helping to ensure greater supply chain continuity for a safety-critical material. Full execution would double European manufacturing capacity for NBG-18 by 2030, with additional capacity investments under consideration across multiple regions to further debottleneck initial billet production. The expansion builds on a 10-year Supplier Framework Agreement established in January 2026, which included an initial three-year award...
