Centrus Energy and Antares Nuclear Form a Multi-Year HALEU Supply Agreement

In a significant development for the nuclear energy sector, Centrus Energy (NYSE: LEU) and Antares Nuclear have officially entered into a multi-year supply agreement focused on High-Assay Low-Enriched Uranium (HALEU). This contract, revealed on September 17, 2026, is poised to bolster the burgeoning demand for advanced nuclear fuels, particularly in support of various national security initiatives and innovative reactor technologies.

Commitment to Clean Energy and Security

The freshly inked contract stipulates that Centrus will supply HALEU to Antares starting before the end of the decade. This strategic arrangement aims to establish a robust domestic source of HALEU, integral to Antares's cutting-edge nuclear reactor projects designed for special missions, including defense and space applications. With prepayments included in the agreement, Antares is also contributing directly to expanding Centrus's HALEU production capacity.

Amir Vexler, President and CEO of Centrus, remarked, "This contract showcases the accelerating demand for HALEU and positions Centrus as a leader in meeting this crucial need. These binding orders support our expansion towards commercial-scale production, which is well underway. We're eager to facilitate Antares's growth and triumph in their respective missions."

On the other hand, Jordan Bramble, CEO and Co-Founder of Antares, highlighted the importance of a reliable fuel supply for advanced reactor developers. He stated, "This partnership grants Antares a dependable source of U.S.-origin HALEU, which is essential for the reactors we are deploying for diverse defense and space clients."

Antares's Innovative Reactor Technology

Antares is renowned for its development of compact microreactors aimed at delivering safe, reliable energy to places where conventional power solutions are unfeasible. The company's flagship Mark-0 microreactor achieved initial criticality in 2026 as part of the DOE Reactor Pilot Program. With plans to start electricity production from advanced reactors by 2027, Antares anticipates deploying its technologies at U.S. military installations by 2028, further underscoring its commitment to national security and innovation.

The Future of HALEU Production

Centrus has positioned itself at the forefront of HALEU production through its American Centrifuge Plant in Piketon, Ohio—recognized as the only licensed HALEU production site in the entire western hemisphere. Their recent multi-billion-dollar expansion is set to enhance both HALEU and Low-Enriched Uranium (LEU) production capabilities, aligning with the increasing demand for nuclear energy solutions that contribute to clean and carbon-free energy agendas.

The contract demonstrates a unique partnership in fostering U.S. national security. With Centrus's U.S.-origin enrichment technology and manufacturing supply chain, Antares obtains fuel that is adaptable for numerous national security uses. Notably, Centrus' AC100 centrifuge technology incorporates 'unobligated' enrichment potential—meaning it can operate effectively within national security frameworks.

Conclusion

As the nuclear energy landscape evolves, the collaboration between Centrus and Antares marks a significant advance in addressing urgently needed energy solutions while enhancing national security frameworks. Both companies are set to play a vital role in uplifting U.S. capabilities in clean energy production and advanced nuclear technology, paving the way for a greener and safer future.
