Definitive purchase agreements include meaningful prepayments and advances Oklo’s planned 1.2 GW Ohio campus with Meta; fuel deliveries beginning in 2029.
Secures fuel to power up to five Aurora powerhouses for multiple years, supporting initial Ohio deployments, future Aurora projects, and additional fuel for the Aurora-INL.
PIKE COUNTY, Ohio--(BUSINESS WIRE)-- Oklo Inc. (NYSE: OKLO) (“Oklo”), an advanced nuclear technology company, today announced it has signed multiple definitive, multi-year contracts with Centrus Energy Corp. (NYSE: LEU) (“Centrus”), a uranium enrichment and nuclear fuel services provider, for high-assay low-enriched uranium (HALEU). Under the agreements, Oklo will make prepayments for future HALEU deliveries to support construction of new U.S. uranium enrichment capacity with Centrus. The agreements formalize the June 2026 letter of intent between Oklo and Centrus and include enough HALEU to support up to five Aurora powerhouses for multiple years, with fuel deliveries from Centrus’ American Centrifuge Plant in Pike County, Ohio, scheduled to begin in 2029.
The HALEU purchase is supported by Meta’s prepayment for future Oklo power production and secures fuel for the first phase of Oklo’s planned 1.2 GW power campus in Ohio. Meta’s previously announced agreement with Oklo linked prepayment for power with advancement of project development. With the funding, Oklo is able to advance fuel procurement with Centrus for the planned Ohio campus, which includes multiple Oklo Aurora powerhouses; expand Ohio’s clean energy workforce; and generate new local and state tax revenues through investment in energy infrastructure.
The fuel supply marks a major step toward scaling Oklo’s power business beyond its first reactor. Building on Oklo’s allocation of recovered Experimental Breeder Reactor II (EBR-II) fuel for its first Aurora powerhouse in Idaho, the Centrus agreements secure HALEU for the first phase of the Ohio power campus, future Aurora deployments, and later refueling of the Aurora-INL.
These agreements and its prepayments will further propel Centrus’ proven centrifuge manufacturing process that recently completed and began shipping its first new centrifuge as part of its domestic uranium enrichment expansion. Centrus has further de-risked its buildout by assembling a complete, unobligated supply chain to serve both the commercial and national security markets. Centrus has now secured $5.4 billion in customer contracts and commitments to purchase LEU and HALEU from the new capacity.
“Securing fuel is essential to scaling our power business beyond our first reactor in Idaho,” said Oklo CEO and co-founder Jacob DeWitte. “These agreements support our initial Ohio deployments and provide fuel for future Aurora powerhouses. Meta’s support helps advance fuel procurement for the Ohio campus and our work to deliver new, clean, reliable power to the grid.”
“These definitive agreements demonstrate that Centrus is ideally placed to meet and support the upcoming substantial commercial demand for HALEU,” said Amir Vexler, President and Chief Executive Officer of Centrus. “Oklo’s prepayments, which add to the others we have previously received, will help fund our buildout as we scale Centrus’ proven American Centrifuge technology and qualified manufacturing processes for commercial production. Together, we are accelerating the restoration of America’s uranium enrichment leadership.”
The agreements connect three Ohio-based efforts: Centrus’ enrichment expansion in Piketon, Oklo’s planned Aurora powerhouses, and Meta’s commitment to bring new electricity and jobs in support of its Ohio operations. With Meta’s committed demand for clean energy catalyzing both the power plant buildout and the domestic fuel purchase, the effort is expected to support thousands of direct and indirect jobs at full buildout and strengthen the fuel supply chain for advanced nuclear deployment across the United States.
