ASP Isotopes Inc.

ASP Isotopes Inc. is an advanced materials company focused on developing an isotope enrichment platform to provide critical materials for nuclear medicine, next-generation semiconductors, and nuclear energy. In January 2026, the company acquired Renergen, which is South Africa's leading onshore natural gas explorer and the first integrated producer of both liquid helium and LNG. The company's proprietary enrichment technologies, the Aerodynamic Separation Process ("ASP technology") and Quantum Enrichment technology ("QE technology"), are designed to produce isotopes for industrial and advanced technology applications. ASP Isotopes Inc.'s initial focus for its isotope enrichment platform is on the production and commercialization of enriched Carbon-14 ("C-14"), Silicon-28 ("Si-28"), and Ytterbium-176 ("Yb-176"). Commercial production of enriched isotopes began at both of its ASP enrichment facilities in Pretoria, South Africa, during the first half of 2025. The first ASP enrichment facility is designed to enrich light isotopes like C-14 and C-12. The second ASP enrichment facility, which is substantially larger, is designed to enrich kilogram quantities of heavier isotopes, including Si-28. The company is producing commercial samples of highly enriched Yb-176 at its third enrichment facility, a QE technology facility and its first laser-based enrichment plant. The company is planning additional isotope enrichment plants in South Africa and other jurisdictions, including Iceland and the United States. The C-14 produced using ASP technology may be used in new pharmaceuticals and agrochemicals, while Si-28 produced using ASP technology may be used in advanced semiconductors and quantum computing.
