Centrus Energy ( LEU 3.23%) is one of the few U.S. companies licensed to sell low-enriched uranium (LEU), the fuel used in most commercial nuclear reactors. It's also the only publicly listed U.S. company that produces high-assay, low-enriched uranium (HALEU) for advanced nuclear reactors. That makes it a linchpin of the nuclear energy market.
