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 UF 6 and U 3 O 8, 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):
| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
United States | $ | 34.1 |  |  | $ | — |  |  | $ | 142.5 |  |  | $ | 86.1 |
Foreign | 10.7 |  |  | 34.8 |  |  | 79.3 |  |  | 141.9
Revenue - SWU and uranium | $ | 44.8 |  |  | $ | 34.8 |  |  | $ | 221.8 |  |  | $ | 228.0 |
Refer to Note 13, Segment Information, for disaggregation of revenue by segment. 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. The DOE reimbursed the Company for 80% of its costs incurred in performing the contract. The DOE has funded the contract up to $173.0 million with a period of performance that ended November 30, 2022. The Company recorded revenue up to the funded amount of $173.0 million and has received aggregate cash payments under the HALEU Demonstration Contract of $171.2 million through September 30, 2025. Closeout activities on the HALEU Demonstration Contract are ongoing. On November 10, 2022, the DOE awarded the HALEU Operation Contract to the Company with a base contract value of approximately $150.0 million in two phases through 2024. Phase 1 included an approximately $30.0 million cost-share contribution from Centrus matched by approximately $30.0 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF 6. On November 7, 2023, the Company announced that it made its first contractual delivery of HALEU to the DOE, completing Phase 1. During November 2023, the Company transitioned to Phase 2 of the HALEU Operation Contract, which included production of 900 kilograms of HALEU UF 6 for one production year, as well as continued operations and maintenance of the cascade. Phase 2 included an initial contract value of approximately $90.0 million and compensation on a cost-plus-incentive-fee-basis. The DOE owns any HALEU produced from the demonstration cascade. The HALEU Operation Contract also gives DOE the ability to exercise three optional periods to contract for up to nine additional years of production from the cascade beyond the base contract; those options are at the DOE’s sole discretion and subject to the availability of Congressional appropriations. 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. Under the HALEU Operation Contract, DOE is contractually obligated to provide the 5B Cylinders necessary to collect the output of the cascade, but supply chain challenges created difficulties for DOE in securing enough 5B Cylinders for the entire Phase 2 production year. During time periods when 5B Cylinders were insufficient, the Company was not able to produce HALEU as it did not have 5B Cylinders to store the enriched uranium. Due to these delays, Centrus was unable to achieve contractual delivery of the 900 kilograms of HALEU UF 6 by November 2024, which was the date set for the end of Phase 2 performance. On November 5, 2024, the HALEU Operation Contract was modified to extend the Phase 2 period of performance to June 30, 2025, which allowed the Company to produce and contractually deliver the Phase 2 production target of 900 kilograms of HALEU to DOE. On August 20, 2025, the DOE modified the HALEU Operation contract to further extend the Phase 2 period of performance through October 31, 2025 to allow the Company to complete outstanding change orders. As of September 30, 2025, the total Phase 2 contract value and funded value is $170.1 million. 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. Additionally, the Amendment acknowledges that the estimated cost associated with Option 1b is insufficient to support full performance due to known cost increases since award of the HALEU Operation Contract and indicates that the Company will need to submit a revised cost proposal for review and negotiation prior to DOE’s consideration of Option 1b. In conjunction with the amendment, the DOE exercised Option 1a and extended the period of performance to June 30, 2026. As of September 30, 2025, Option 1a is funded for the contract value of $108.2 million. Under the HALEU Operation Contract, the Company submitted several change order requests for work being performed on infrastructure, facility repairs, and 5B Cylinders. The additional work is being performed under the DOE Contracting Officer’s approval or contract modifications. On September 28, 2023, the DOE modified the HALEU Operation Contract to incorporate additional scope for infrastructure and facility repairs, and costs associated with 5B Cylinder refurbishment, for an estimated additional contract value of $5.8 million, without a cost-share provision. DOE is now obligated for costs up to the contract value of $8.8 million for the additional scope work. 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 September 30, 2025, DOE is obligated for costs up to $316.2 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 $195.4 million through September 30, 2025. 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. 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 $0.7 billion and $0.8 billion as of September 30, 2025, and December 31, 2024, 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 $0.6 billion and $0.7 billion as of September 30, 2025 and December 31, 2024, 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 $154.8 million and $216.4 million of Deferred Revenue and Advances from Customers at September 30, 2025, and December 31, 2024, respectively. T he 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. T he 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. T he 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 $98.7 million and $28.0 million, as of September 30, 2025, and December 31, 2024, 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 The following table presents the components of accounts receivable (in millions):
|  | September 30, 2025 |  | December 31, 2024
Accounts receivable: |  |  |  |
Billed |  | $ | 44.1 |  |  | $ | 69.8 |
Unbilled * |  | 16.6 |  |  | 10.2 |
Accounts receivable |  | $ | 60.7 |  |  | $ | 80.0 |
* 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.
Contract Liabilities The following table presents changes in contract liability balances (in millions):
|  | September 30, 2025 |  | December 31, 2024 |  | Year-To-Date Change
Deferred revenue - current |  | $ | 154.8 |  |  | $ | 183.6 |  |  | $ | (28.8) |
Advances from customers - current |  | $ | — |  |  | $ | 32.8 |  |  | $ | (32.8) |
Previously deferred sales and advances from customers recognized in revenue totaled $68.5 million and $99.6 million in the nine months ended September 30, 2025 and 2024, respectively.
