Overview
We are an advanced materials company dedicated to the development of a differentiated isotope enrichment platform to strengthen global supply chain access to critical materials used in nuclear medicine, next-generation semiconductors, and nuclear energy. Our proprietary enrichment technologies, the Aerodynamic Separation Process (“ASP technology”) and QE technology, are designed to enable the production of isotopes for a range of industrial and advanced technology applications. Our initial focus is on the production and commercialization of enriched Carbon-14 (“C-14”), Silicon-28 (“Si-28”) and Ytterbium-176 (“Yb-176”).
We commenced commercial production of enriched isotopes at both of our ASP enrichment facilities located in Pretoria, South Africa during the first half of 2025. However, we have not generated any revenue from the sale of our enriched isotopes as of June 30, 2026. Our first ASP enrichment facility is designed to enrich light isotopes, such as C-14 and C-12. The second ASP enrichment facility, which is substantially larger than the first, should have the potential to enrich kilogram quantities of relatively heavier isotopes, including but not limited to Si-28. Depending on the timing and the quality of the feedstock received from our customer, we are targeting initial commercial shipments of enriched C-14 in the second half of 2026. We are targeting initial commercial shipments of enriched Si-28 in the second half of 2026. We have also completed the commissioning phase of our third enrichment facility, a QE technology facility, which is our first laser-based enrichment plant. We are targeting initial commercial shipments of Yb-176 in the second half of 2026.
In addition, we have started planning additional isotope enrichment plants both in South Africa and in other jurisdictions, including Iceland and the United States. We believe the C-14 we may produce using the ASP technology could be used in the development of new pharmaceuticals and agrochemicals. We believe the Si-28 we may produce using the ASP technology may be used to create advanced semiconductors and in quantum computing. We believe the Yb-176 we may produce using the QE technology may be used to create radiotherapeutics that treat various forms of oncology. We are considering the future development of the ASP technology for the separation of Zinc-68 and Xenon-129/136 for potential use in the healthcare end market, Germanium 70/72/74 for potential use in the semiconductor end market, and Chlorine -37 for potential use in the nuclear energy end market. We are also considering the future development of QE technology for the separation of Nickel-64, Gadolinium-160, Ytterbium-171, Lithium-6 and Lithium-7.
QLE, our subsidiary, is currently pursuing an initiative to apply our enrichment technologies to the enrichment of Uranium-235 (“U-235”) in South Africa. We believe that the U-235 QLE may produce has the potential to be commercialized as a nuclear fuel component for use in the new generation of high-assay low-enriched uranium (“HALEU”)-fueled small modular reactors that are now under development for commercial and government uses. In furtherance of our uranium enrichment initiative in South Africa, we have entered into certain definitive agreements with TerraPower, LLC (“TerraPower”), including a term loan subject to conditions to support construction of a new uranium enrichment facility at Pelindaba, South Africa and supply agreements for the future supply of HALEU to TerraPower, as a customer. In addition, QLE’s South African subsidiary has entered into a Pre-Implementation Services Contract Agreement (“Services Contract”) with The South African Nuclear Energy Corporation (“Necsa”), a South African state-owned company responsible for undertaking and promoting research and development in the field of nuclear energy and radiation sciences, pursuant to which Necsa has agreed to provide to QLE’s South African subsidiary certain facilities, infrastructure, utilities and services related to the siting, design, construction, commission and operation of an enrichment facility on the Necsa site in Pelindaba. In the period since our inception to date, we have not applied our 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. Our expectation that QLE’s initiative to apply our enrichment technologies to the enrichment of U-235 could be successful is based upon research conducted by certain of our scientists prior to joining the company, as well as the demonstrated effectiveness of QE technology on Yb-176.
We acquired Renergen in January 2026 and issued 14,270,000 Consideration Shares in connection with this acquisition. Renergen is South Africa’s leading onshore natural gas explorer and the first integrated producer of both liquid helium and LNG, both of which are produced from the natural gas reserve base that underpins Renergen’s Virginia Gas Project. The Virginia Gas Project includes (i) the liquefaction of natural gas into LNG, (ii) the separation of helium from natural gas, and (iii) the further liquefaction of helium into 99.999% pure liquid helium. This liquefaction and separation takes place at Renergen’s Virginia Gas Plant. Renergen’s principal asset is its 94.5% equity ownership in Tetra4, which holds an onshore petroleum production right and is the entity developing the Virginia Gas Project.
QLE entered into the Securities Exchange Agreement with a third party, effective as of March 29, 2026, which resulted in the deconsolidation of Skyline (Note 21). QLE retained approximately 8.6% percent of the outstanding Class A common and preferred shares of Skyline immediately following deconsolidation.
Our Subsidiaries and Segments
We operate principally through our subsidiaries. ASP Isotopes Guernsey Limited (the holding company for our subsidiaries in the Cayman Islands, South Africa, Iceland and the United Kingdom) is focused on the development and commercialization of high-value, low-volume isotopes for highly specialized end markets (such as C-14, Si-28, and Yb-176). ASP Isotopes UK Ltd is the owner of our
37
technology.
QLE. In September 2023, we formed QLE, which also has subsidiaries in the United Kingdom (Quantum Leap Energy Limited) and South Africa (Quantum Leap Energy (Pty) Limited), to focus on the development and commercialization of advanced nuclear fuels, such as HALEU and Lithium-6. QLE’s direct wholly owned subsidiary QLE UK, has its operations in the United Kingdom. QLE UK’s direct wholly owned subsidiary, QLE South Africa, has its operations in South Africa. QLE also formed QLE SPE Borrower, as a wholly owned subsidiary to act as a special purpose borrower for a loan transaction with TerraPower, a US nuclear innovation company. The QLE SPE Borrower has formed a subsidiary in South Africa to act as the project company for a proposed new uranium enrichment facility at Pelindaba, South Africa.
QLE’s mission is to address perceived gaps in the nuclear fuel cycle, promote safe nuclear power, and enhance the sustainability of the nuclear fuel cycle for advanced nuclear reactors and fusion systems, as well as the existing nuclear fleet. We believe that many advanced nuclear reactors, including SMRs, will rely on fuels with higher uranium enrichment levels, specifically HALEU, which we intend to produce. QLE also intends to produce high-isotopic purity fuel feedstock, such as Lithium-6, for fusion reactors, and by extension, Lithium-7 for Light Water Reactor control. These fuels may enable greater efficiency, compact reactor footprints, and lengthened operational cycles between refueling. Given the flexible nature of our enrichment technology and integrated value chain approach, QLE also intends to make available LEU+ to the existing fleet of nuclear reactors currently running on LEU, thus enabling existing reactors to lengthen the time between refueling, cut costs and boost power output.
As previously announced, our board of directors intends to pursue the separation of our Nuclear Fuels business and Specialist Isotopes and Related Services business in two independent companies. The regulatory landscape and supply chain for nuclear fuel production differs significantly from that of medical isotopes, hence we and QLE have different business models and we believe that both companies would benefit if QLE is independently managed and financed. We plan to effect the separation through a listing of QLE in a transaction that results in QLE existing as a separate public company with shares listed on a U.S. national securities exchange and a portion of QLE’s common equity being distributed to our stockholders as of a to-be-determined future record date. While we currently believe that a listing of QLE as a separate public company is the most likely separation transaction, our board of directors remains committed to maximizing shareholder value creation, and will continue to evaluate other options for separation to maximize shareholder value.
We entered into a number of agreements with QLE, including a License Agreement, pursuant to which QLE has licensed from us the rights to technologies and methods used to separate U-235 and Lithium-6 (including but not limited to the QE and ASP technologies) in exchange for a perpetual royalty in the amount of 10% of all future QLE revenues, and an EPC Services Framework Agreement, pursuant to which we will provide services for the engineering, procurement and construction of one or more turnkey U-235 and Lithium-6 enrichment facilities in locations to be identified by QLE and owned or leased by QLE, and commissioning, start-up and test services for each such facility, subject to the receipt of all applicable regulatory approvals, permits, licenses, authorizations, registrations, certificates, consents, orders, variances

We are targeting initial commercial shipments of enriched C-14 in mid-2026. We are targeting initial commercial shipments of enriched Si-28 during the second quarter of 2026. We have also completed the commissioning phase and are producing commercial samples of highly enriched Yb-176 at our third enrichment facility, a QE technology facility, which is our first laser-based enrichment plant. We are targeting initial commercial shipments of Yb-176 in mid-2026 or the third quarter of 2026.
In addition, we have started planning additional isotope enrichment plants both in South Africa and in other jurisdictions, including Iceland and the United States. We believe the C-14 we may produce using the ASP technology could be used in the development of new pharmaceuticals and agrochemicals.

QLE acquired a controlling interest in Skyline in August 2025. Skyline is a holding company, and its operations are conducted through its wholly owned operating subsidiary, Kin Chiu Engineering Limited. Operations primarily consist of construction activities which include public civil engineering works, such as road and drainage works, in Hong Kong. Skyline mostly undertakes civil engineering works in the role as a subcontractor but is fully qualified to undertake such works in the capacity of a main contractor. QLE intends to pursue opportunities to acquire assets in the critical materials supply chain.
We acquired Renergen in January 2026. Renergen is South Africa’s leading onshore natural gas explorer and the first integrated producer of both liquid helium and LNG, both of which are produced from the natural gas reserve base that underpins Renergen’s Virginia Gas Project. The Virginia Gas Project includes (i) the liquefaction of natural gas into LNG, (ii) the separation of helium from natural gas, and (iii) the further liquefaction of helium into 99.999% pure liquid helium. This liquefaction and

separation takes place at Renergen’s Virginia Gas Plant. Renergen’s principal asset is its 94.5% equity ownership in Tetra4, which holds an onshore petroleum production right and is the entity developing the Virginia Gas Project.
Our Subsidiaries and Segments
We operate principally through our subsidiaries. ASP Isotopes Guernsey Limited (the holding company for our subsidiaries in the Cayman Islands, South Africa, Iceland and the United Kingdom) is focused on the development and commercialization of high-value, low-volume isotopes for highly specialized end markets (such as C-14, Mo-100, and Si-28). ASP Isotopes UK Ltd is the owner of our technology.
Beginning in 2024, primarily as a result of increased business activities of our subsidiary, QLE, we had two operating segments: (i) nuclear fuels, and (ii) specialist isotopes and related services. Beginning in August 2025, primarily as a result of the acquisition of Skyline, we have three operating segments: (i) nuclear fuels, (ii) specialist isotopes and related services, and (iii) construction services.
QLE. In September 2023, we formed QLE, which also has subsidiaries in the United Kingdom (Quantum Leap Energy Limited) and South Africa (Quantum Leap Energy (Pty) Limited), to focus on the development and commercialization of advanced nuclear fuels, such as HALEU and Lithium-6. QLE’s direct wholly owned subsidiary QLE UK, has its operations in the United Kingdom. QLE UK’s direct wholly owned subsidiary, QLE South Africa, has its operations in South Africa. QLE also formed QLE SPE Borrower, as a wholly owned subsidiary to act as a special purpose borrower for a loan transaction with TerraPower, a US nuclear innovation company. The QLE SPE Borrower has formed a subsidiary in South Africa to act as the project company for a proposed new uranium enrichment facility at Pelindaba, South Africa.
QLE’s mission is to address perceived gaps in the nuclear fuel cycle, promote safe nuclear power, and enhance the sustainability of the nuclear fuel cycle for advanced nuclear reactors and fusion systems, as well as the existing nuclear fleet. We believe that many advanced nuclear reactors, including SMRs, will rely on fuels with higher uranium enrichment levels, specifically HALEU, which we intend to produce. QLE also intends to produce high-isotopic purity fuel feedstock, such as Lithium-6, for fusion reactors, and by extension, Lithium-7 for Light Water Reactor control. These fuels may enable greater efficiency, compact reactor footprints, and lengthened operational cycles between refueling. Given the flexible nature of our enrichment technology and integrated value chain approach, QLE also intends to make available LEU+ to the existing fleet of nuclear reactors currently running on LEU, thus enabling existing reactors to lengthen the time between refueling, cut costs and boost power output.
As previously announced, our board of directors intends to pursue the separation of our Nuclear Fuels business and Specialist Isotopes and Related Services business in two independent companies. The regulatory landscape and supply chain for nuclear fuel production differs significantly from that of medical isotopes, hence we and QLE have different business models and we believe that both companies would benefit if QLE is independently managed and financed. We plan to effect the separation through a listing of QLE in a transaction that results in QLE existing as a separate public company with shares listed on a U.S. national securities exchange and a portion of QLE’s common equity being distributed to our stockholders as of a to-be-determined future record date. Although no assurance can be given, our goal is to list QLE on such exchange, subject to market conditions, obtaining applicable approvals and consents, and complying with applicable rules and regulations and public market trading and listing requirements. In November 2025, we announced that QLE had confidentially submitted a draft registration statement on Form S-1 to the SEC relating to the proposed initial public offering of QLE’s Class A common stock. While we currently expect that a listing of QLE as a separate public company is the most likely separation transaction, our board of directors remains committed to maximizing shareholder value creation, and will continue to evaluate other options for separation to maximize shareholder value.
We entered into a number of agreements with QLE, including a License Agreement, pursuant to which QLE has licensed from us the rights to technologies and methods used to separate U-235 and Lithium-6 (including but not limited to the QE and ASP technologies) in exchange for a perpetual royalty in the amount of 10% of all future QLE revenues, and an EPC Services Framework Agreement, pursuant to which we will provide services for the engineering, procurement and construction of one or more turnkey U-235 and Lithium-6 enrichment facilities in locations to be identified by QLE and owned or leased by QLE, and commissioning, start-up and test services for each such facility, subject to the receipt of all applicable regulatory approvals, permits, licenses, authorizations, registrations, certificates, consents, orders, variances and similar rights.
PET Labs. We have a 51% ownership stake in PET Labs, a South African radiopharmaceutical operations company focused on the production of fluorinated radioisotopes and active pharmaceutical ingredients, through which we entered the downstream medical isotope production and distribution market.
