ASP Isotopes Inc. (ASPI) disclosed on July 21, 2026, that it has issued a press release announcing a research agreement with the Texas A&M Engineering Experiment Station, known as TEES. The agreement is intended to advance and de-risk the commercial production of high-purity uranium hexafluoride, or UF₆, which the company described as a critical feedstock used in the existing nuclear fuel enrichment supply chain. The filing was made under Item 7.01, Regulation FD Disclosure, meaning the company furnished the announcement to broadly disclose the development to investors. The press release itself was attached as Exhibit 99.1. The company did not report a securities issuance, financing, merger, acquisition, executive change, insider transaction, or other share-based corporate action in this 8-K. No share counts, transaction prices, option terms, vesting schedules, insider ownership changes, or transaction codes were included because the filing concerns a research collaboration rather than a purchase or sale of securities. The practical significance is that ASP Isotopes is signaling a step toward technical validation and commercialization of UF₆ production, a material relevant to nuclear fuel enrichment infrastructure. The company also noted that the information in Item 7.01 and the accompanying press release is being “furnished” rather than formally “filed” for liability purposes under the Securities Exchange Act, and that the press release contains forward-looking statements covered by the Private Securities Litigation Reform Act safe harbor. The report was signed on behalf of ASP Isotopes by Donald G. Ainscow, Executive Vice President, General Counsel and Secretary.
