ASP Isotopes to list on JSE, ships first Silicon-28 samples, to host investor call.

ASP Isotopes will host an investor access event on August 26, 2025, in Pretoria, South Africa. The company expects to list on the Johannesburg Stock Exchange on August 27, 2025, and has shipped its first enriched Silicon-28 samples to a US-based customer. The management team will also feature on a RedChip Investor call on August 28, 2025.

ASP Isotopes Inc. (NASDAQ: ASPI) will host an investor access event on August 26, 2025, in Pretoria, South Africa, ahead of its anticipated secondary listing on the Johannesburg Stock Exchange (JSE) on August 27, 2025. The company has made significant strides in its commercial production of isotopes, including the shipment of its first enriched Silicon-28 samples to a US-based customer. The management team will also feature on a RedChip Investor call on August 28, 2025.

ASP Isotopes has been actively progressing with its isotope production facilities. The company has shipped its first Silicon-28 samples to a US customer and expects to complete Ytterbium-176 enrichment in August 2025. The Ytterbium facility has achieved a 52x enrichment factor, though there is a 3-4 week delay in transitioning to semi-continuous processing due to supply chain issues. The Carbon-14/12 facility is now producing 99.99% enriched Carbon-12, with first commercial delivery expected in September 2025. Additionally, ASP Isotopes continues to progress on two major corporate initiatives: the planned spin-out of Quantum Leap Enrichment (QLE) in H2 2025 and the anticipated closure of the Renergen acquisition in Q3 2025.

ASP Isotopes demonstrates commercial production progress across multiple isotopes with strategic international expansion via JSE listing. This press release showcases significant operational milestones across ASP Isotopes' portfolio of specialized isotope production facilities. The company has successfully shipped its first samples of enriched Silicon-28 to a US customer, marking a critical commercialization step for a material believed essential for next-generation quantum computing and advanced semiconductors. The ability to produce highly enriched Silicon-28 addresses two crucial semiconductor challenges - quantum decoherence and thermal management - as it's both spin-free and can potentially conduct heat 150% more efficiently than natural silicon.

The company's Ytterbium-176 production has achieved impressive 92.4% enrichment with an enrichment factor of 52, exceeding their target of 50. While they've experienced a 3-4 week delay in transitioning to semi-continuous processing due to supply chain issues, they're still on track for commercial shipments in August. This demonstrates technical proficiency in isotope separation but reveals some vulnerability to supply chain disruptions.

The Carbon isotope facility shows strategic flexibility by pivoting to Carbon-12 production (99.99% enrichment) due to stronger market demand and feedstock delays for Carbon-14 production. This adaptability to market conditions is particularly valuable in the specialized isotopes sector. Their expansion into Nickel-64, Gadolinium-160, and Zinc-68 enrichment, accelerated based on performance data from their first Quantum Enrichment facility, indicates confidence in their technological approach.

The impending JSE listing, while not a capital-raising event, suggests strategic positioning to attract South African investment, potentially leveraging local connections for their Pretoria facilities. The scheduled spinoff of Quantum Leap Enrichment and pending Renergen acquisition further indicate an active corporate development strategy focused on expanding their specialized materials portfolio.
