ASP Isotopes Announces Quantum Leap Energy is Evaluating Metal Conversion Opportunities in Namibia

DALLAS, August 18, 2026 - ASP Isotopes Inc. (NASDAQ: ASPI) ("ASPI") today announced that Quantum Leap Energy LLC ("we," "QLE" or the "Company"), a wholly-owned subsidiary of ASPI dedicated to advancing innovative technologies and processes across critical segments of the fission and fusion nuclear fuel cycle, is evaluating metal conversion opportunities in Namibia.

As part of this evaluation, a public environmental and social impact assessment and consultation process has commenced for a proposed pilot-scale hydrofluorination and fluorination facility in the Walvis Bay area of Namibia. The proposed facility would be used to develop, test and demonstrate hydrofluorination and fluorination processes for metals.

In accordance with Namibian regulatory requirements, public consultation notices have been published through customary local channels, including in the Republikein, Allgemeine Zeitung, and The Namibian newspapers.

The evaluation remains at an early stage, and no final investment decision has been made. Any future development would be subject to technical, commercial, environmental and regulatory review and approvals.

About Quantum Leap Energy

Quantum Leap Energy is a development stage nuclear fuels company dedicated to advancing innovative technologies and processes across critical segments of the nuclear fuel cycle. The company focuses on uranium conversion, enrichment of uranium-235 for nuclear fuel production (HALEU, LEU+ and LEU), and isotopic separation of lithium-6 and lithium-7, as well as radioactive waste treatment technologies. Through exclusive global rights to proprietary Aerodynamic Separation Process (ASP) and laser-based Quantum Enrichment (QE) technologies, Quantum Leap Energy aims to address perceived gaps in the nuclear fuel supply chain for advanced nuclear reactors, small modular reactors, and fusion systems. The company has established strategic partnerships or commercial initiatives and relationships with industry leaders including TerraPower, Fermi America, and the South Africa Nuclear Energy Corporation (Necsa) to accelerate the commercialization of critical isotopes essential for next-generation nuclear energy systems. *The company has not applied its enrichment technologies to the enrichment of U-235, nor received permission or regulatory approval to conduct testing of our enrichment technologies on U-235, except for the activities contemplated by the services contract with Necsa.
