ASP Isotopes Inc. Announces Proposed Secondary Listing on the Johannesburg Stock Exchange

WASHINGTON , April 24, 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, is pleased to announce the proposed secondary listing of the Company’s common stock by way of introduction on the Main Board of the Johannesburg Stock Exchange (“JSE”).   The Company’s common stock will continue to be listed and traded on the Nasdaq Capital Market.

ASPI’s history and technology is firmly rooted in South Africa and has been developed over four years by the Company’s highly skilled South African team members. Furthermore, ASPI has three plants in Pretoria where it is refining the commercial production of Carbon-14 (“C-14”), Silicon-28 (“Si-28”) and Ytterbium-176 (“Yb-176”) to be used across the pharmaceutical, medical, quantum computing and semiconductor industries.

ASPI believes that admission to trading of its shares on the JSE will be beneficial to the Company and its stakeholders as it will enhance liquidity for shareholders, diversify the Company’s shareholder base and position ASPI for growth, by providing access to another deep capital market.

Given ASPI’s South African footprint, its specialised and disruptive technologies, its strong management team, size of markets and global demand for ASPI’s products and its anticipated near-term production capacity, the Company expects strong interest and support for a JSE listing from South African institutional investors.

The listing of ASPI on the JSE is expected to be by way of introduction and to become effective later this year, subject to the necessary regulatory approvals in South Africa.

Paul Mann, Chairman and CEO of ASP Isotopes and CEO of QLE said, “While our investor base has been created in the USA and Europe, the beating heart of our company is clearly currently in South Africa, with 97% of our employees and all our operating assets being located in South Africa. We have to thank our South African staff, service providers and regulators for helping us achieve all we have done over the last four years and therefore we owe it to South Africa to make our securities available to the local community.”

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