Totaling over 37,800 sq.-ft, the addition of the K-1580 Building complements LIST’s growing real estate portfolio and footprint, building on its existing 206-Acre “LIST Island” land parcel, and State-of-the-Art Test Demonstration Facility at K-1330, located at the historic K-25 Enrichment Site of East Tennessee’s Technology Park Heritage Center.
Oak Ridge, Tennessee, Aug. 12, 2026 (GLOBE NEWSWIRE) — LIS Technologies Inc. (“LIST” or “the Company”), a developer of proprietary advanced laser technology and the only USA-origin and patented laser uranium enrichment company, is pleased to announce that it has expanded its presence in Oak Ridge, Tennessee’s historic Heritage Center and K-25 Enrichment Site with the acquisition of the K-1580 Building, a prominent, newly-renovated, three-level, 37,803 square-foot facility, for a total of $6.2 million.

“We are delighted to continue growing our base of operations in Oak Ridge, Tennessee, or what I call the Silicon Valley of Nuclear,” said Jay Yu, Executive Chairman and CEO of LIS Technologies Inc. “The acquisition of the K-1580 building marks the beginning of a new chapter for LIST. Additionally, it underscores our drive and ability to rapidly expand and utilize our proprietary and patented laser uranium enrichment technology across a full spectrum of potential applications, including medical and stable isotopes and nuclear fuel cycle applications. We plan to scale operations further in complementary segments as we position the Company to meet our long-term growth goals.”
The K-1580 Building, located on 150 Americus Way in East Tennessee’s Technology Park Heritage Center, expands LIST’s presence on the footprint of the former K-25 gaseous diffusion plant, a cornerstone of the Manhattan Project. K-1580 will act as a complementary facility to LIST’s existing leased State-of-the-Art Test Demonstration Facility located at the adjacent K-1330 Building. The acquisition and build out of the K-1580 facility will enable LIST to, amongst other developments, actively engage in the production of key stable and medical isotopes, expanding its product offering beyond enriched nuclear fuel, and establishing a firmer foundation for long-term growth by addressing multiple industry segments.

K-1580 will host LIST’s Medical Isotopes and Stable Isotope production capabilities. Hospitals rely on a robust supply of precursor -stable and enriched- isotopes to produce the medical isotopes used in diagnostics as well as disease treatment. Similarly, stable isotopes are becoming increasingly critical to advanced electronics and quantum technologies, enhancing thermal management, enabling higher performance, efficiency, and reliability in advanced processor applications. K-1580’s multiple floors are expected to provide a foundation for growth in additional segments as well.
“Besides a Pilot Plant for our SMILE (Stable and Medical Isotope Laser Enrichment) program, the K-1580 building will also serve to further expand our supplementary business operations,” said Christo Liebenberg, President and Co-Founder of LIS Technologies Inc. “It will provide office space for over 100 additional employees and be home to our Pilot Plant for UF6 Deconversion. The building will also serve to industrialize some of the critical components needed for our laser enrichment of uranium program. The proximity to our K-1330 building will ensure that our team has direct, easy access to both facilities as we continue to shape the future of the nation’s laser enrichment capabilities.”
“The addition of the K-1580 Building provides expanded laboratory space to support the development of Phase II uranium enrichment capabilities at scale within a prototypical operating environment,” said Lloyd Jollay, Chief Operating Officer of LIS Technologies Inc. “The facility also offers dedicated laboratory space for investigating UF6 deconversion processes. Integrating deconversion capabilities with uranium enrichment will create a more comprehensive fuel cycle solution and address key needs expressed by a number of advanced reactor developers.”
The CRISLA-3G laser isotope separation technology being developed by LIST has been determined to meet all elements required for Technology Readiness Level 4 (TRL-4), conforming to the Department of Energy guide DOE G 413.3-4A. The technology has already matured to approximately 75% TRL-5, with excellent progress also towards TRL-6. LIST’s laser-based isotope separation technology is designed to potentially deliver greater efficiency, improved scalability, and a reduced facility footprint compared with conventional methods.
