Oklo and Centrus Sign Definitive HALEU Contracts for Ohio Campus

Oklo said on 12 November 2026 that it has signed “multiple definitive, multi-year contracts” with Centrus Energy for high-assay low-enriched uranium, or HALEU, to supply its planned power campus in Pike County, Ohio. The companies said the agreements include prepayments, formalise a June 2026 letter of intent, and cover “enough HALEU to support up to five Aurora powerhouses for multiple years,” with deliveries from Centrus’s American Centrifuge Plant in Pike County “scheduled to begin in 2029.”

Oklo said 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.” No value was given for the Oklo–Centrus contracts themselves.

Centrus, in a Form 8-K filed the same day, said it had “signed a contract with Oklo, Inc. to supply high-assay low-enriched uranium” and attached the press release as exhibit 99.1. The 8-K body uses the singular “a contract”; the release, which both companies put out, refers to “multiple definitive, multi-year contracts.” This article reports both wordings and does not treat the 8-K’s shorthand as a different deal.

Prepayments, five Aurora units and a 2029 start

Under the agreements, Oklo said it will make prepayments for future HALEU deliveries “to support construction of new U.S. uranium enrichment capacity with Centrus.” The fuel is to come from the American Centrifuge Plant in Pike County. Oklo said Meta’s previously announced agreement “linked prepayment for power with advancement of project development,” and that with that funding it can advance fuel procurement for the planned Ohio campus.

Oklo CEO and co-founder Jacob DeWitte said: “Securing fuel is essential to scaling our power business beyond our first reactor in Idaho.” He added: “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.”

Amir Vexler, president and chief executive of Centrus, said: “These definitive agreements demonstrate that Centrus is ideally placed to meet and support the upcoming substantial commercial demand for HALEU.” In the same release, Centrus said Oklo’s prepayments “add to the others we have previously received” and will help fund its enrichment expansion.

The same release states that Centrus “has now secured $5.4 billion in customer contracts and commitments to purchase LEU and HALEU from the new capacity.” That is a company-wide figure for low-enriched uranium and HALEU contracts and commitments, not the value of the Oklo agreements, which was not disclosed.

Ohio power, Meta and other nuclear projects stay distinct

The campus described here is Oklo’s planned 1.2 GW project in Ohio, backed by a Meta power prepayment. TSN has previously reported on Meta’s Prometheus gigawatt-scale Ohio supercluster. Those are both Ohio energy stories involving Meta. Neither Oklo’s 12 November release nor Centrus’s 8-K says that the HALEU under these contracts is being bought to power Prometheus, and this article does not treat the two projects as the same site.

The fuel deal also sits in a wider US push to pair new nuclear capacity with large compute loads. TSN has covered Japan’s plan to invest in US nuclear reactors to power AI data centres and, more recently, the NRC construction permit for the Long Mott small modular reactor project in Texas. Those are separate projects, with different owners, fuels and regulators’ actions. They are useful context for why HALEU supply has become a commercial bottleneck; they are not part of this contract.

A fuel contract is not a plant that is already running

The announcement is a supply agreement, not a declaration that the Ohio campus is built or that Aurora units there are generating power. Deliveries are “scheduled to begin in 2029.” The contracts, on Oklo’s account, cover enough HALEU for up to five Aurora powerhouses for multiple years, and they formalise a letter of intent signed in June 2026. A letter of intent becoming a definitive contract is a real step. It is not the same thing as fuel already being shipped, or as a completed first reactor in Ohio.

Two wording traps are worth keeping in view. First, Oklo speaks of “multiple” contracts; Centrus’s 8-K body speaks of “a contract” and then incorporates the release. Readers should not infer a contradiction that the filings themselves do not explain. Second, the $5.4 billion figure is easy to misread as the size of this deal. It is not. It is Centrus’s own total of customer contracts and commitments for LEU and HALEU from new capacity.

Meta’s role is also easy to over-read. The companies say the HALEU purchase is supported by Meta’s prepayment for future Oklo power, and that an earlier Meta–Oklo agreement linked a power prepayment to project development. That is financial support for fuel procurement. It is not, on the disclosed facts, a statement of how much power Meta will take, at what price, or from which units, and no such figures appear in the 12 November materials.

Finally, DeWitte’s reference to scaling “beyond our first reactor in Idaho” is a company description of Oklo’s plans, not evidence that an Idaho unit is already in commercial operation, or that the Ohio campus has cleared every licensing step. The Long Mott permit, by contrast, was a specific NRC construction permit for a different project. Nothing in today’s release claims an equivalent permit for the Ohio Aurora campus.
