ASP Isotopes has previously announced that it has signed three commercial contracts for the supply of enriched Silicon-28 to U.S.-based customers, and expects to make initial commercial shipments of enriched Silicon-28 in Q3 2026.

The first 18 stages (comprising segments one and two) of the Silicon-28 enrichment facility have now successfully operated for over three weeks at target enrichment levels.

Engineering modifications made over the past nine months addressed non-core components, including valves and compressors; these same engineering enhancements are expected to be implemented to the remaining stages of the enrichment facility to enable commercial production of enriched Silicon-28.
