Shares of Centrus Energy opened sharply higher in pre-market trading, climbing 8.2% after the company and advanced nuclear firm Oklo disclosed a Letter of Intent (LOI) for a multi-year fuel supply arrangement. Under the LOI, Centrus would provide domestically produced high-assay low-enriched uranium - known as HALEU - sufficient to power as many as five of Oklo's planned Aurora powerhouses, with deliveries slated to begin in 2029.
The proposed supply deal is explicitly connected to Oklo's envisioned 1.2 gigawatt clean energy campus in southern Ohio. For Centrus, the agreement represents a concrete commercial commitment tied to its American Centrifuge Plant in Pike County, the focal point of the company's multibillion-dollar expansion in enrichment capacity.
Beyond the operational significance, the LOI has financial contours that bear noting. The document contemplates potential prepayments from Oklo to Centrus to underwrite fuel supply ahead of the campus construction - a payment structure similar to an arrangement Oklo previously struck with Meta. Those prepayments could provide Centrus with upfront liquidity to support early-stage production commitments.
Centrus has indicated it will rely on a combination of private financing and a previously awarded $900 million HALEU task order from the U.S. Department of Energy to fulfill its supply obligations. That mix of government-backed demand and private capital support reinforces an existing narrative among analysts that sustained, policy-driven HALEU demand could underpin the company’s long-term growth plans.
Market context highlighted that the move was company-specific. Major indexes did not provide a lift: the S&P 500 fell 1.2%, the Dow Jones Industrial Average declined 1.0%, and the Nasdaq Composite slipped 1.3% on the same trading day. The divergence underscores that Centrus’s pre-market rally was driven by the fuel supply announcement rather than broader market gains.
Oklo itself also traded higher on the news, reflecting investor interest in the developing domestic fuel supply chain for advanced nuclear technologies. For Centrus, the LOI supplies a named customer, a stated volume and a delivery timeline - turning a strategic ambition for HALEU production into an explicit commercial commitment that investors have been awaiting.
At the same time, this agreement comes against a backdrop of recent challenges for low-enriched uranium and related names, including analyst price target cuts and a first-quarter earnings miss for Centrus. The LOI functions as a tangible counterbalance to those headwinds by providing an identifiable revenue pathway tied to a named project.
Key takeaways
- Centrus announced an LOI to supply HALEU to Oklo for up to five Aurora powerhouses, with fuel deliveries planned to start in 2029.
- The deal ties Centrus’s Pike County American Centrifuge Plant to Oklo’s planned 1.2 gigawatt clean energy campus in southern Ohio and contemplates potential prepayments to support early supply.
- Centrus intends to use private capital alongside a $900 million DOE HALEU task order to meet its obligations; the announcement was company-specific amid a weaker broader market.
Risks and uncertainties
- The LOI is a preliminary agreement and not necessarily a definitive supply contract, leaving execution risk for the planned deliveries and volumes.
- Centrus continues to face headwinds that included analyst price target reductions and a recent first-quarter earnings miss, which the LOI may only partially offset.
- Financial plans rely on a mix of private capital and the previously awarded $900 million DOE task order, introducing potential funding and timing uncertainties tied to project ramp-up.
