Centrus Energy and Oklo Sign Nuclear Fuel Agreement, Shares Rise

Centrus Energy (LEU) and Oklo Inc. (OKLO) announced on June 18, 2026 a Letter of Intent under which Centrus will supply enough high-assay low-enriched uranium (HALEU) to fuel up to five Aurora powerhouses for multiple years, with deliveries scheduled to begin in 2029 . The agreement is tied to Oklo's planned 1.2 GW Clean Energy Campus in southern Ohio, one of the most ambitious commercial advanced nuclear projects announced in the United States to date. Centrus Energy shares rose approximately 8.21% on the news.

The HALEU fuel is earmarked to come from Centrus's American Centrifuge Plant in Pike County, Ohio, the only domestic HALEU enrichment facility operating under a U.S. Department of Energy demonstration program. That domestic sourcing is a central element of the deal's strategic rationale: supplying advanced reactor fuel without dependence on foreign enrichers. The LOI contemplates potential prepayments from Oklo to Centrus to support fuel supply during the multi-year campus buildout, with a definitive supply agreement to be negotiated in a subsequent phase .

Oklo Co-founder and CEO Jacob DeWitte stated the agreement aligns three core pillars of advanced nuclear deployment: power generation, fuel supply, and customer demand. Centrus President and CEO Amir Vexler framed the deal as helping establish a new U.S. advanced nuclear energy hub in the region. The project could bring over 700 construction jobs during the multi-year deployment and 40 to 50 permanent positions per powerhouse, with Centrus's own expansion adding an estimated 1,000 construction jobs and 300 operating roles in Ohio .

The deal reflects a broader acceleration in domestic HALEU contracting as advanced reactor developers seek to lock in fuel before commercial-scale enrichment capacity comes fully online. Centrus currently produces HALEU under a DOE contract and is working toward expanding commercial production capacity. For investors, the key execution risks remain the timeline: Aurora powerhouse construction, NRC licensing milestones, and Centrus's ability to scale enrichment output on schedule. The LOI is non-binding, and a definitive agreement has not yet been signed, meaning near-term revenue recognition is limited.
