SGL Carbon is a German specialty materials manufacturer selected by X-energy in a 10-year graphite supply agreement in January 2026 to supply reactor core components for the Xe-100 high-temperature gas-cooled reactor, including an initial three-year award valued at over $100 million for the first commercial deployment. Graphite is the moderator material in HTGR pebble-bed reactors and must meet stringent nuclear-grade specifications. SGL Carbon is one of the world's leading manufacturers of nuclear-grade graphite components, making it the natural supply partner for X-energy's Xe-100 commercial deployment programme.
