[{"type":"text","content":"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. DALLAS, May 26, 2026 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. (NASDAQ: ASPI) (“ASP Isotopes” or the “Company”), an advanced materials company focused on developing technologies and processes for the production of critical materials used in multiple industries, today announced that the Company has successfully restarted the first 18 stages (comprising segments one and two) of its Silicon-28 enrichment facility located in Pretoria, South Africa. The Company shipped its first samples of enriched Silicon-28 to a U.S. customer in August 2025, and independent analysis confirmed that enrichment levels tracked in line with theoretical calculations. Following customer site visits in 2H 2025, the Company began implementation of numerous modifications to non-core elements of the Silicon-28 enrichment facility, such as valves, compressors, and piping. Having implemented these planned enhancements and operated the first 18 stages of the Silicon-28 enrichment facility for over three weeks, ASPI’s engineering team believes that they have found an optimized engineering solution. These same engineering enhancements are expected to be implemented to the remaining stages of the Silicon-28 enrichment facility to enable commercial production of enriched Silicon-28 safely and efficiently. “While the core enrichment technology has been operating in line with our expectations, many of the non-core components did not operate in line with the specifications provided by the OEM suppliers,” said Heino Van-Wyk, Head of Engineering at ASP Isotopes. “The engineering team have worked tirelessly over the last nine months to correct these peripheral issues to construct a plant t...
