## Exhibit 99.1

**EXHIBIT 99.1**

**ASP Isotopes Inc. Enhances the Quantum Leap Energy LLC**

**(QLE) Executive Leadership Team with the Appointment of**

**Ryno Pretorius as Chief Executive Officer of QLE**

Washington, D.C., June 11, 2025 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. NASDAQ: ASPI ("ASP Isotopes" or the "Company"), an advanced materials company dedicated to the development of technology and processes for the production of isotopes for use in multiple industries, today announced the appointment of Dr. Ryno Pretorius, PhD as Chief Executive Officer of Quantum Leap Energy LLC (QLE), the Company's subsidiary that is pursuing an initiative to develop and commercialize advanced nuclear fuels, such as High Assay Low-Enriched Uranium (HALEU) and Lithium-6. Dr. Pretorius has previously served as a consultant to both ASP Isotopes and QLE.

Paul Mann will continue to serve as the chairman and CEO of ASPI and the chairman of QLE.

Dr. Pretorius has spent the last decade and a half as a practicing chemical engineer facilitating technology scale-up for multiple organizations globally. Importantly, he spent four years working for Necsa (South African Nuclear Energy Company) at Pelindaba, where he gained a comprehensive understanding of the nuclear fuel supply chain, fluorination's role in nuclear fuel production and technology scale-up. He has spent the last ten years as technical director and CEO of Free Radical Process Design, a global consulting firm specializing in the design, development and economic evaluation of engineering technologies and processes where he managed a team of chemical engineers and chemists to solve technical challenges for many companies globally. Free Radical Process Design has been one of ASP Isotopes' key consultants that has been engaged in solving chemical engineering problems associated with isotope enrichment facilities.

Dr. Pretorius has a B. Eng, B. Eng (Hons) and an M. Eng in chemical engineering from the University of Pretoria, as well as a PhD in chemical engineering from the University of Pretoria, where he specialized in fluorochemical engineering and developed a novel fluorination process in the critical materials value-chain. In addition, he also attended the postgraduate program in Data Science and Business Analytics at the University of Texas, Austin. Dr. Pretorius is registered as a Professional Engineer (Pr. Eng - Chemical Engineering) in South Africa. He is the inventor of two patented processes, the first covering electrochemical recovery of trace metals from dilute aqueous streams and in the production of heavy metal fluorides with a reduced CAPEX and OPEX process. Dr. Pretorius is an author or coauthor on a number of scientific papers and articles focussing on gas-solid chemistry, halogenation reactions, electrochemistry and fluorine production. Dr. Pretorius will be based in Austin, Texas, which is set to become the global headquarters of both ASP Isotopes and QLE following the closing of the previously announced acquisition of Renergen Limited.

"*As we prepare for the spin out of QLE, anticipated during 2H 2025, it is an important step to build out the senior leadership team of QLE in order for it to become a standalone company. We have got to know Ryno well over the past four years. His understanding of the nuclear fuel supply chain industry, as well as solving process engineering challenges is second to none and he will make an exceptional leader of our nuclear fuels focused subsidiary*", said Paul Mann, Executive Chairman and Chief Executive Officer of ASP Isotopes.

*"I am excited to join and lead QLE during this important stage of its corporate growth and beyond. Having already spent four years working with the teams at ASP Isotopes and QLE to help overcome many of the engineering challenges that their groundbreaking enrichment methods have encountered., I feel highly confident that we can bring new technologies to the world to solve a growing supply shortage of nuclear fuels and energy isotopes"* said Dr. Pretorius*.* 

As previously announced, QLE and certain of its subsidiaries has entered into a loan agreement and certain other related agreements with TerraPower, a US nuclear innovation company, related to financing support for the construction of a new uranium enrichment facility capable of producing HALEU at Pelindaba in South Africa. QLE is also in discussions with other governments and expects to build enrichment facilities in other regions, specifically the UK and the USA.

ASP Isotopes believes its proprietary Quantum Enrichment process will be able to produce HALEU at an attractive price, allowing new nuclear energy to become available at a "green discount" to carbon-intensive electricity production processes. This "green energy cost advantage" is expected to help accelerate the global adoption of new nuclear energy, with a corresponding benefit to climate goals. The Quantum Enrichment process, an isotope enrichment method under development by the Company's scientists, is a laser-based enrichment method, which it believes will have both the lowest levelized cost of HALEU production, the lowest cash operating cost of HALEU production, low capital expenditure, and efficient construction cycles. The Company's first Quantum Enrichment Facility, for the production of Ytterbium-176, completed its commissioning phase during 1H 2025 and is currently in the process of enriching commercial samples for customers, which the Company expects to ship during 3Q 2025.

HALEU will be required to enable advanced nuclear reactors, such as SMRs (small modular reactors), which are now under development for commercial and government uses, to operate in the future. Currently, there are no Western producers of HALEU in commercial quantities, and many SMR companies worldwide face substantial delays until this fuel supply issue is resolved. The Nuclear Energy Institute estimates that there may be a HALEU supply demand of approximately 3,000 metric tons by 2035. However, based on discussions with and the interest received from potential customers, the Company believes this figure may be significantly larger.

During the next 30 years, global energy consumption is expected to double. To meet 2050 climate goals, this must occur with a zero increase in carbon emissions. The advanced nuclear fuels required during the next 50 years are expected to differ significantly from those used in the last 50 years. Specifically, many small modular and advanced nuclear reactors in the future are expected to require HALEU.

**Inducement Grant**

In connection with his appointment as Chief Executive Officer of Quantum Leap Energy LLC, the Company granted Dr. Pretorius 30,000 shares of the Company's common stock. Subject to Dr. Pretorius being continuously employed by the Company or QLE through each applicable vesting date, the shares will vest in eight equal instalments over four years, with 3,750 shares on each of the six-month anniversaries of Dr. Pretorius' employment start date. This restricted stock award was approved by the Company's Compensation Committee and Board of Directors and granted under the Company's 2024 Inducement Equity Incentive Plan as an inducement material to Dr. Pretorius entering into employment with QLE, in accordance with Nasdaq Listing Rule 5635(c)(4).

**About ASP Isotopes Inc.**

ASP Isotopes Inc. is a development stage advanced materials company dedicated to the development of technology and processes to produce isotopes for use in multiple industries. The Company employs proprietary technology, the Aerodynamic Separation Process ("ASP technology"). The Company's initial focus is on producing and commercializing highly enriched isotopes for the healthcare and technology industries. The Company also plans to enrich isotopes for the nuclear energy sector using Quantum Enrichment technology that the Company is developing. The Company has isotope enrichment facilities in Pretoria, South Africa, dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes).

There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing, and Molybdenum-100, Molybdenum-98, Zinc-68, Ytterbium-176, and Nickel-64 for new, emerging healthcare applications, as well as Chlorine-37, Lithium-6, and Uranium-235 for green energy applications. We believe the ASP technology (Aerodynamic Separation Process) is ideal for enriching low and heavy atomic mass molecules. For more information, please visit <u>www.aspisotopes.com</u>.
