Revenue from Contract with Customer [Abstract] |
Revenue from Contract with Customer | REVENUE AND CONTRACTS WITH CUSTOMERS 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,
| 2024 |  | 2023 |  | 2024 |  | 2023
United States | $ | — |  |  | $ | 16.9 |  |  | $ | 86.1 |  |  | $ | 148.4 |
Foreign | 34.8 |  |  | 23.6 |  |  | 141.9 |  |  | 38.5
Revenue - SWU and uranium | $ | 34.8 |  |  | $ | 40.5 |  |  | $ | 228.0 |  |  | $ | 186.9 |
Refer to Note 13, Segment Information, for disaggregation of revenue by segment. 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 services provided to the U.S. government and its contractors. SWU and uranium revenue is recognized when the customer obtains control of the SWU or uranium components and Technical Solutions’ revenue is generally recognized over time based on direct costs incurred or the right to invoice method (in situations where the value transferred matches the Company’s billing rights) as the customer receives and consumes the benefits. Accounts Receivable

|  | (in millions)
Accounts receivable: |  |  |  |
Billed |  | $ | 10.2 |  |  | $ | 40.2 |
Unbilled * |  | 8.9 |  |  | 9.2 |
Accounts receivable |  | $ | 19.1 |  |  | $ | 49.4 |
* 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 the customer and approved. 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, 2024 |  | December 31, 2023 |  | Year-To-Date Change
Deferred revenue - current |  | $ | 189.8 |  |  | $ | 252.4 |  |  | $ | (62.6) |
Advances from customers - current |  | $ | 32.8 |  |  | $ | 30.2 |  |  | $ | 2.6 |
Advances from customers - noncurrent |  | $ | — |  |  | $ | 32.8 |  |  | $ | (32.8) |
Previously deferred sales and advances from customers recognized in revenue totaled $99.6 million and $23.6 million in the nine months ended September 30, 2024 and 2023, respectively. LEU Segment 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. Technical Solutions Segment Revenue for the Technical Solutions segment, representing the Company’s technical, manufacturing, engineering, procurement, construction, and operations services offered to public and private sector customers, is recognized over the contractual period as services are rendered. Under the 2019 HALEU Demonstration Contract, the Company constructed a cascade of 16 centrifuges to demonstrate production of HALEU for advanced reactors. The DOE agreed to reimburse 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 received aggregate cash payments under the HALEU Demonstration Contract of $171.2 million through September 30, 2024. Closeout activities on the HALEU Demonstration Contract are ongoing. The DOE elected to move the operational portion of the HALEU Demonstration Contract to a subsequent, competitively awarded contract and, on November 10, 2022, the DOE awarded the HALEU Operation Contract to the Company, and work began on December 1, 2022. The base contract value is approximately $150 million with two phases through 2024. Phase 1 included an approximately $30 million cost-share contribution from Centrus matched by approximately $30 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF 6 by no later than December 31, 2023. On October 11, 2023, the Company announced that it began enrichment operations in Piketon, Ohio. On November 7, 2023, the Company announced that it made its first delivery of HALEU to the DOE, completing Phase 1 by successfully demonstrating its HALEU production process. Phase 2 of the HALEU Operation Contract includes production of 900 kilograms per year of HALEU UF 6, as well as continued operations and maintenance. The DOE owns the HALEU produced from the demonstration cascade and Centrus is being compensated on a cost-plus-incentive-fee basis, with an expected Phase 2 contract value of approximately $90 million, subject to Congressional appropriations. The HALEU Operation Contract also gives DOE options to pay 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 obligated to provide the 5B Cylinders necessary to collect the output of the cascade, but supply chain challenges have created difficulties for DOE in securing enough 5B Cylinders for the entire production year. Centrus’ delivery of the 900 kilograms of HALEU UF 6, which it no longer can achieve by November 2024, was conditioned on the DOE’s ability to provide the 5B Cylinders on a timeline that allows for continuous production throughout Phase 2 of the contract. During time periods when 5B Cylinders are insufficient, the Company is able to continue operation of the cascade, but is not able to produce HALEU. The 9% target fee for Phase 2 of the contract was estimated to be $7.5 million based on the estimated costs for the contract and is subject to a contract minimum fee of $6.9 million. To support the DOE in mitigating the risk of further delays in delivery of 5B Cylinders, the Company received technical direction and a contract modification from the DOE to procure compliant 5B Cylinders and components. The contractual obligation to furnish compliant 5B Cylinders under the HALEU Operation Contract continues to rest with the DOE. In accordance with the HALEU Operation Contract, the Company has 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’s technical direction or contract modifications. On September 28, 2023, the DOE modified the HALEU Operation Contract to incorporate additional scope, not subject to cost-share reimbursement, for infrastructure and facility repairs, and costs associated with 5B Cylinder refurbishment, for an estimated additional contract value of $6.2 million. The DOE is currently obligated for costs up to approximately $6.2 million for the additional scope under the HALEU Operation Contract. 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. When estimates of program costs to be incurred for an integrated, construction-type contract exceed estimates of total revenue to be earned, a provision for the remaining loss on the contract is recorded to Cost of Sales in the period the loss is determined. The Company’s corporate costs supporting the program are recognized as expense as incurred over the duration of the contract term. The Company recorded an accrued loss of $21.3 million related to anticipated cost-share reimbursement under the HALEU Operation Contract in Cost of Sales in December 2022. The accrued loss on the contract was adjusted over the contract term based on actual results and remaining program cost projections through December 31, 2023. The impact to Cost of Sales in the three and nine months ended September 30, 2023 was $5.4 million and $16.7 million, respectively, for previously accrued contract losses attributable to work performed in those periods. The HALEU Operation Contract is funded incrementally, and the DOE currently is obligated for costs up to approximately $118.4 million of the $126.3 million estimated transaction price for Phase 1, Phase 2, and additional scope work. The Company has received aggregate cash payments under the HALEU Operation Contract of $95.2 million through September 30, 2024. 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 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 $1.0 billion as of September 30, 2024, and December 31, 2023, 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 $0.8 billion and $1.0 billion for September 30, 2024, and December 31, 2023, respectively, and extend to 2030. The remaining performance obligations represent the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries and includes approximately $223 million and $315 million of Deferred Revenue and Advances from Customers at September 30, 2024, and December 31, 2023, respectively. The remaining performance obligations are partially based on customer estimates of the timing and size of their 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 $18.0 million and $77.0 million, as of September 30, 2024, and December 31, 2023, respectively, and extend to 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.
