HALEU is the binding constraint on the entire advanced-reactor buildout and the West is structurally short of it, so Centrus Energy and ASP Isotopes are two ways to own that chokepoint. Centrus is the only US enricher that has actually delivered first-of-a-kind HALEU, over 920 kg under its DOE contract, now extended through 2026 with options for eight more years, and it is profitable at about a $3 billion market cap. ASP Isotopes is the laser-enrichment challenger scaling behind it. x.comÂ
