EXHIBIT 99.1
Quantum Leap Energy and Necsa Sign Binding Heads of Agreement to Establish Joint Venture for HALEU Production in South Africa
Joint Venture Supported by Offtake Agreements with TerraPower, Initial Regulatory Approvals, and Access to Site Infrastructure to enable QLE and Necsa to Advance Toward Commercial-Scale HALEU Production
DALLAS, October 15, 2026 (GLOBE NEWSWIRE)
-- ASP Isotopes Inc. (NASDAQ: ASPI) ("ASPI") today announced that a subsidiary of Quantum Leap Energy LLC ("QLE," the "Company" or “Quantum Leap Energy”), a wholly-owned subsidiary of ASPI, has signed a Heads of Agreement (the "Agreement") with the Nuclear Energy Corporation of South Africa SOC Limited ("Necsa"). The Agreement establishes a binding commercial framework for a joint venture between QLE and Necsa (the “Joint Venture”) to develop, finance, construct, commission, own, and operate a test bench and commercial-scale facility for the production of High-Assay Low-Enriched Uranium ("HALEU") at Necsa's Pelindaba site in South Africa.
"The world needs new, reliable and secure sources of advanced nuclear fuel, and South Africa is well placed to provide them," said Loyiso Tyabashe, Group Chief Executive Officer of Necsa. “Through this partnership with Quantum Leap Energy, Necsa will bring its decades of experience in nuclear operations, safeguards and regulatory compliance to creating a trusted new source of commercial HALEU supply.”
The Agreement marks a significant step forward in QLE's relationship with Necsa, building on the Memorandum of Understanding signed in November 2024 and the Pre-Implementation Services Contract signed in February 2026. Meaningful progress has already been made on the ground. In July 2026, QLE received approval from South Africa's Ministry of Electricity and Energy to acquire, possess, use, dispose of and transport source material and nuclear related equipment and technology to advance uranium enrichment activities at Pelindaba. At Pelindaba, a test bench facility was previously constructed, and the refurbishment of the infrastructure housing the test bench is currently underway, while engagements with the relevant authorities have commenced. Further, QLE has already secured offtake for the HALEU the Joint Venture is expected to produce through supply agreements with TerraPower, one of the world's leading advanced nuclear reactor developers.
"This agreement demonstrates real commercial progress and brings us one step closer to enrichment," said Dr. Ryno Pretorius, Chief Executive Officer of Quantum Leap Energy. “We are proud to be working alongside Necsa, whose nuclear site, infrastructure and expertise no other partner could replicate. With offtake from TerraPower already in place, we are positioned to deliver the HALEU that will fuel the next generation of nuclear reactors.”
Under the agreed principles, QLE will hold approximately 80% of the ownership interest in the Joint Venture and lead operations and the arrangement of capital. Necsa will hold approximately 20% of the Joint Venture and contribute site access, nuclear safeguards support, and licensing and regulatory support that are essential to progressing HALEU production in South Africa.
As the statutory nuclear energy institution of the Republic of South Africa, Necsa brings deep nuclear expertise, infrastructure, regulatory relationships and licensing capability to the Joint Venture. Necsa is headquartered at Pelindaba, South Africa's premier nuclear research center, home to the 20MW SAFARI-1 research reactor and the site of more than six decades of nuclear activity. The parties also intend for Necsa to enter an engineering, procurement and construction arrangement with QLE, giving the project direct access to Necsa's engineering capabilities. QLE believes that combining its proprietary enrichment technology with Necsa's established nuclear platform offers a highly efficient route to commercial HALEU production.
