Revenue from Contract with Customer [Abstract]  
Revenue from Contract with Customer REVENUE AND CONTRACTS WITH CUSTOMERS
Revenue for the LEU segment is derived from the sales of the SWU component of LEU, from sales of both the SWU and uranium components, and from sales of UF6 and U3O8, to electric utility customers and other nuclear fuel related companies. Technical Solutions revenue is derived from advanced manufacturing and other technical services provided to the U.S. government and private sector customers.

LEU Segment

SWU and uranium revenue is recognized when the customer obtains control of the SWU or uranium components. The SWU component of LEU typically is sold under contracts with deliveries over several years. The Company’s agreements for natural uranium hexafluoride and uranium concentrate sales generally are shorter-term, fixed-commitment contracts. Most of the Company’s customer contracts provide for fixed purchases of SWU during a given year. Depending on the terms of specific contracts, the customer may be able to increase or decrease the quantity delivered within an agreed range.
Disaggregation of Revenue

The following table presents revenue from SWU and uranium sales disaggregated by geographical region based on the billing addresses of customers (in millions):

Technical Solutions Segment

Revenue for the Technical Solutions segment, representing the Company’s uranium enrichment, advanced manufacturing, and other technical services offered to public and private sector customers, is recognized over time as the performance obligation is satisfied or at the point in time in which each performance obligation is fully satisfied.

The Company’s work on HALEU began under the HALEU Demonstration Contract, signed with the DOE in 2019, to construct a cascade of 16 centrifuges to demonstrate production of HALEU for advanced reactors. Following the HALEU Demonstration Contract, in November 2022, the DOE awarded the HALEU Operation Contract to the Company with an initial base contract value of approximately $150.0 million in two phases through 2024, with three optional periods for up to nine additional years of production beyond the base contract. Those options are at the DOE’s sole discretion and subject to the availability of Congressional appropriations.

In November 2023, the Company announced that it made its first contractual delivery of HALEU to the DOE, completing Phase 1 of the HALEU Operation Contract. As a result of delays in obtaining 5B Cylinders DOE is contractually obligated to provide under the HALEU Operation Contract, Phase 2 of the HALEU Operation Contract was extended through June 2025, when Centrus contractually delivered 900 kilograms of HALEU UF6 to DOE, completing Phase 2. The fee for the Phase 2 period of performance that was extended beyond November 30, 2024 was not definitized and is subject to negotiation.

On June 17, 2025, the DOE issued an amendment to the HALEU Operation Contract that split the first three-year option period into a first option period of one year (“Option 1a”) and a second option period of two years (“Option 1b”). The amendment established a target cost and fee for Option 1a of approximately $99.3 million and $8.7 million, respectively, and a target cost and fee for Option 1b of $163.5 million and $15.2 million, respectively. In conjunction with the amendment, the DOE exercised Option 1a and extended the period of performance to June 30, 2026. As of March 31, 2026, Option 1a is funded for the contract value of $108.2 million.

Costs under the HALEU Operation Contract include program costs, including direct labor and materials and associated indirect costs that are classified as Cost of Sales, and an allocation of corporate costs supporting the program that are classified as Selling, General and Administrative Expenses. The HALEU Operation Contract is funded incrementally, and as of March 31, 2026, DOE is obligated for costs up to $317.0 million in the aggregate for Phase 1, Phase 2, Option 1a of Phase 3, and the additional scope work. The Company has received aggregate cash payments under the HALEU Operation Contract of $247.8 million through March 31, 2026.
The Company does not have a contractual obligation to perform work in excess of the funding provided by the DOE. If the DOE does not commit to additional costs above the existing funding, the Company may incur material additional costs or losses in future periods that could have an adverse impact on its financial condition and liquidity. The DOE owns any HALEU produced from the demonstration cascade. Pursuant to an amendment to the Company’s lease for the Piketon facility, the DOE assumed all D&D liabilities arising out of the HALEU Operation Contract.

Remaining Performance Obligations

The Company’s remaining performance obligations represent the aggregate amount of the total contract transaction price that is unsatisfied or partially unsatisfied. Performance obligations are recognized as revenue in future periods as work is performed or deliveries of SWU and uranium are made. The Company’s total remaining performance obligations were $0.8 billion and $0.6 billion as of March 31, 2026, and December 31, 2025, respectively, and extend to 2030.

The remaining performance obligations in the LEU segment, primarily related to medium and long-term contracts with fixed commitments, were approximately $0.7 billion and $0.6 billion as of March 31, 2026 and December 31, 2025, respectively, and extend to 2030. The remaining performance obligations represent the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries and include approximately $112.8 million and $131.1 million of Deferred Revenue and Advances from Customers at March 31, 2026, and December 31, 2025, respectively. The remaining performance obligations are partially based on customer estimates of the timing and size of the customers’ fuel requirements and other assumptions that are subject to change. The remaining performance obligations include estimates of selling prices, which may be subject to change. Depending on the terms of specific contracts, prices may be adjusted based on escalation using a general inflation index, published SWU price indicators prevailing at the time of delivery, and other factors, all of which are variable. The Company uses external composite forecasts of future market prices and inflation rates in its pricing estimates.

The remaining performance obligations in the Technical Solutions segment were approximately $48.1 million and $79.1 million, as of March 31, 2026, and December 31, 2025, respectively, and extend through 2026. The remaining performance obligations in Technical Solutions include both funded (services for which funding has been both authorized and appropriated by the customer) and unfunded (services for which funding has not been appropriated) amounts. The Company does not include unexercised options or potential services under indefinite-delivery, indefinite-quantity agreements in its remaining performance obligations. If any of the Company’s contracts were to be terminated, its remaining performance obligations would be reduced by the expected value of the cancelled performance obligations of such contracts.

Accounts receivable$41.8 $30.7 
* Billings under certain contracts in the Technical Solutions segment are invoiced based on approved provisional billing rates. Unbilled revenue represents the difference between actual costs incurred and invoiced amounts. The Company expects to invoice and collect the unbilled amounts after actual rates are submitted to and approved by the customer. Unbilled revenue also includes unconditional rights to payment that are not yet billable under applicable contracts due to timing of invoice processing or pending the compilation of supporting documentation.
