Insights

Corporate Finance Strategist

ASP Isotopes' JSE dual listing strengthens its South African presence while its Renergen acquisition creates a strategic materials powerhouse.

ASP Isotopes is executing a dual-pronged geographic expansion strategy with its upcoming Johannesburg Stock Exchange listing scheduled for August 27th while simultaneously acquiring South African company Renergen. The JSE listing is particularly strategic as 97% of ASPI's employees and all operating assets are already located in South Africa, making this a natural market extension rather than a speculative venture.

The pending Renergen acquisition (approved by 99.8% of Renergen shareholders) creates substantial vertical and horizontal integration in critical materials production. The combined entity will focus on electronic gases, fluorinated products, and isotopically enriched gases – all considered strategically vital materials by Western governments.

Management projects ambitious financial targets, expecting the deal to be accretive across all key metrics by 2026 with a goal of generating over $300 million in EBITDA by 2030. This growth depends on successfully executing business strategies across isotopes, helium, and LNG sales into the South African energy market.

The transaction timing is notable – ASPI expects to complete the Renergen acquisition in Q3 2025, before spinning out QLE in the second half of 2025. While the JSE listing doesn't depend on completing the Renergen acquisition, ASPI acknowledges trading volume will likely remain limited until the acquisition closes.

This strategic move establishes ASPI as a significant player in critical materials with substantial growth potential, though actual performance will depend on successful integration and market development.

WASHINGTON, Aug. 08, 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 provided an update on its application to list on the Johannesburg Stock Exchange (“JSE”).

The JSE has approved the listing of the Company’s common stock on the Main Board of the JSE under the abbreviated name “ASPI”, share code “ISO” and international securities identification number US00218A1051, with commencement of trading expected on Wednesday, August 27, 2025. The Company will retain its primary listing on the Nasdaq Capital Market and its issued share capital will be unaffected by the secondary, or dual, listing on the JSE. The secondary listing of the Company’s common stock on the JSE is not in connection with any current capital raising effort.

On May 20, 2025, the Company announced its intention to acquire Renergen Limited (“Renergen”), pursuant to a South African scheme of arrangement, under which Renergen shareholders will receive 0.09196 new ASP Isotopes shares for each Renergen share held on the record date (“Scheme”), with the goal of creating a global critical materials company. Renergen shareholders approved the resolution relating to the approval of the Scheme (with support from 99.8% of voting shareholders) at the Renergen general meeting held on July 10, 2025. The implementation of the Scheme however remains subject to the fulfilment or, alternatively, the waiver (where permitted) of the remaining offer conditions, which the Company expects to occur during 3Q 2025. The secondary listing of the Company’s common stock on the JSE is not conditional upon the Scheme being implemented, but until such time as the Scheme is implemented, the Company expects trading in its shares on the JSE to be limited.

The combination of these two highly complementary businesses aims to create a global leader in the production of critical and strategically important materials, including electronic gases such as helium, various fluorinated products and isotopically enriched gases. The combination is expected to create a vertically and horizontally integrated supply chain with significant geographic and customer overlap with substantial synergies expected from 2026.

The transaction is expected to be highly accretive to ASPI’s revenue, EBITDA, earnings per share and cash flow per share during 2026. The goal of the combined group is to generate over $300 million in EBITDA in 2030, which is expected to be driven by a mix of isotopes, helium and LNG sales into the South African energy market, based on management’s current estimates, expectations and assumptions regarding the execution on ASP Isotopes’s and Renergen’s business strategies. The acquisition of Renergen is expected to close during 3Q 2025, prior to the spin out of QLE which is still expected to occur during 2H 2025.

Paul Mann, Chairman and CEO of ASP Isotopes said, “While our capital base has been created in the USA and Europe, the heartbeat of our company is clearly in South Africa, with 97% of our employees and all our operating assets currently being located in South Africa. We have to thank the South African people for helping us achieve all we have done over the last four years and therefore we owe it to the South African people to make our securities available on the JSE.”

Commenting on the proposed combination, Paul Mann continued: “Our acquisition of Renergen is an exciting step for ASP Isotopes. Both isotopes and helium are viewed by almost every Western government as critically and strategically important materials. The combination of these two businesses will create a company with huge strategic value and a vital part of a fragile supply chain enabling a number of industries.”

Valeo Capital Proprietary Limited has been appointed as the sole South African Corporate Advisor and JSE Sponsor for the listing.

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 www.aspisotopes.com.

Use of Projections

The financial outlook and projections, estimates and targets in this press release are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainty and contingencies, many of which are beyond ASP Isotopes’s or Renergen’s control. Such calculation cannot be predicted with reasonable certainty and without unreasonable effort because of the timing, magnitude and variables associated with the completion of the proposed transaction with Renergen. Additionally, any such calculation, at this time, would imply a degree of precision that could be confusing or misleading to investors. Neither ASP Isotopes nor Renergen’s independent auditors have audited, reviewed, compiled or performed any procedures with respect to the financial projections for purposes of inclusion in this press release, and, accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purposes of this press release. While all financial projections, estimates and targets are necessarily speculative, ASP Isotopes believes that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. The assumptions and estimates underlying the projected, expected or target results for ASP Isotopes, Renergen and the combined company are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the financial projections, estimates and targets.
