General Matter
General Matter is a haleu facility operated by General Matter in United States. Its capacity is not publicly disclosed.
One of the four companies the DOE selected in October 2024 to supply HALEU, and awarded a ten-year indefinite-delivery contract in January 2026. It was a recently registered California company at the time of selection with no operating history in enrichment. Recorded here because a quarter of the American HALEU strategy rests on it and almost nothing about it is on the public record.
