Summary of Significant Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation and Principles of Consolidation The Consolidated Financial Statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary Enrichment Corp., and its other subsidiaries, were prepared in conformity with U.S. GAAP. Certain prior year amounts have been reclassified for consistency with the current year presentation. All material intercompany transactions have been eliminated.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts presented and disclosed in the Consolidated Financial Statements. Significant estimates and judgments include, but are not limited to, revenue and related costs, asset valuations, pension and postretirement health and life benefit costs and obligations, the tax bases of assets and liabilities, the future recoverability of deferred tax assets, and determination of the valuation allowance for deferred tax assets. Actual results may differ from such estimates, and estimates may change if the underlying conditions or assumptions change.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include short-term or highly liquid assets with original maturities of three months or less.
Inventory, Policy [Policy Text Block]	Inventories and Inventories Owed to Customers and Suppliers LEU consists of two components: SWU and UF6. SWU is a standard unit of measurement that represents the effort required to transform a given amount of natural uranium into two components: enriched uranium having a higher percentage of U235 and depleted uranium having a lower percentage of U235. The SWU contained in LEU is calculated using an industry standard formula based on the physics of enrichment. The amount of enrichment deemed to be contained in LEU under this formula is commonly referred to as its SWU component and the quantity of UF6 deemed to be used in the production of LEU under this formula is referred to as its uranium or “feed” component. SWU and uranium inventory costs are determined using the average cost method. SWU and uranium purchase costs include shipping costs when applicable. Inventories of SWU and uranium are valued at the lower of cost or NRV. NRV is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The estimated selling price for SWU and uranium is based on the pricing terms of contracts in the Company’s backlog, and, for uranium not under contract, the estimated selling price is based primarily on published price indicators at the balance sheet date. Inventories owed to customers and suppliers, included in current liabilities, consist primarily of SWU and uranium inventories owed to fabricators. Fabricators process LEU into fuel for use in nuclear reactors. As delivery obligations under actual customer orders arise, Centrus typically satisfies these obligations by arranging for the transfer to the customer of title to the specified quantity of LEU at the fabricator. Centrus’ balances of SWU and uranium may vary over time based on the timing of customer orders and Centrus’ delivery of LEU. Balances can be positive or negative based on Centrus’ contractual agreements with the fabricators. In cases where the transfer of title of LEU from Centrus to the customer results in quantities of SWU and uranium being owed by Centrus to the fabricator, the amounts of SWU and uranium owed to fabricators are satisfied as future deliveries of LEU to fabricators are made.
Income Tax, Policy [Policy Text Block]	Deferred Taxes Centrus follows the asset and liability approach to account for deferred taxes. Deferred tax assets and liabilities are recognized for the anticipated future tax consequences of temporary differences between the balance sheet carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are based on income tax rates in effect for the years in which temporary differences are expected to reverse. The effect on deferred taxes of a change in income tax rates is recognized in income when the change in rates is enacted in the law. A valuation allowance is provided if it is more likely than not that all, or some portion, of the deferred tax assets may not be realized.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment Property, plant and equipment are recorded at acquisition cost. Leasehold improvements and machinery and equipment are depreciated on a straight-line basis over the shorter of the useful life of the assets or the lease term, if applicable. Refer also to Carrying Value of Long-Lived Assets below.
Intangible Assets, Policy [Policy Text Block]	Intangible Assets Centrus has intangible assets resulting from fresh start accounting as a result of emergence from Chapter 11 bankruptcy on September 30, 2014. The identifiable intangible assets relate to the sales backlog and customer relationships. The backlog intangible asset is amortized as the backlog valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized using the straight-line method over the estimated average useful life of 15 years, with 3 ¾ years of scheduled amortization remaining. Refer also to Carrying Value of Long-Lived Assets below. Carrying Value of Long-Lived Assets The Company evaluates the carrying values of property, plant and equipment and identifiable intangible assets when events or changes in business circumstances indicate that the carrying amount of asset, or asset group, may not be fully recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset, or asset group, exceeds its fair value.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Financial Instruments and Fair Value Measurement Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, consideration is given to the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability. Pursuant to accounting standards, Centrus’ 0% Convertible Notes due August 2032 and 2.25% Convertible Notes due November 2030 are recorded at face value and carrying value respectively, and the fair value is disclosed. Centrus’ 8.25% Notes due February 2027 were recorded at face value and carrying value respectively, and the fair value as of December 31, 2024 is disclosed. The 8.25% Notes were redeemed on March 26, 2025. The estimated fair value of the 0% Convertible Notes, 2.25% Convertible Notes and 8.25% Notes are based on bid/ask quotes as of or near the balance sheet date. Debt issuance costs are deferred and amortized over the life of the instrument. The balance sheet carrying amounts for accounts receivable, accounts payable and accrued liabilities, and payables under inventory purchase agreements approximate fair value because of the short-term nature of the instruments.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Credit Risk Credit risk could result from the possibility of a customer failing to perform or pay according to the terms of a contract. Extension of credit is based on an evaluation of each customer’s financial condition. Centrus regularly monitors credit risk exposure and takes steps intended to mitigate the likelihood of such exposure resulting in a loss.
Segment Reporting, Policy [Policy Text Block]	Segments Centrus operates two business segments: LEU, which supplies various components of nuclear fuel to commercial customers from our global network of suppliers, and Technical Solutions, which provides advanced uranium enrichment for the nuclear industry and the U.S. government and advanced manufacturing and other technical services to government and private sector customers and advanced uranium enrichment for the nuclear industry and the U.S. government.
Revenue Recognition, Policy	Revenue The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue for product and service sales is recognized when or as the Company transfers control of the promised products or services to the customer. Revenue is measured at the transaction price, which is based on the amount of consideration that the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price will include estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. SWU and Uranium Revenue Revenue for the Company’s LEU segment is derived from sales of the SWU component of LEU, sales of both the SWU and uranium components of LEU, sales of conversion credits, and sales of UF6 and U3O8. Contracts with customers are primarily medium and long-term, fixed-commitment, contracts under which its customers are obligated to purchase a specified quantity of the SWU component of LEU or the SWU and uranium components of LEU. The Company’s contracts for UF6 and U3O8 are generally shorter-term, fixed-commitment contracts. Revenue is recognized at the time the customer obtains control of the LEU or uranium. Customers generally obtain control of LEU at nuclear fuel fabricators. Centrus ships LEU to nuclear fuel fabricators for scheduled or anticipated orders from utility customers. Based on customer orders, Centrus arranges for the transfer of title of LEU from Centrus to the customer for the specified quantity of LEU at the fuel fabricator. Each such delivery to a customer is accounted for as a distinct performance obligation under a contract, and a contract may call for multiple deliveries over a number of periods. The contract’s transaction price is allocated to each performance obligation based on the observable standalone selling price of each distinct delivery of SWU or uranium. For certain contracts the customers may elect not to take control of the LEU or uranium and Centrus may have the right to enforce payment under the terms of the contractual agreement. The revenue recognition for these contracts is assessed when it occurs. Utility customers in general have the option to defer receipt of uranium products purchased from the Company beyond the contractual sale period. In such cases, title to SWU and/or uranium components are transferred to the customer and a performance obligation for Centrus is created and a receivable is recorded. Cash is collected for the receivable under normal credit terms. The performance obligation is represented as deferred revenue in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet and the customer-titled product is classified as Deferred Costs Associated with Deferred Revenue on the Consolidated Balance Sheet. Risk of loss remains with Centrus until the customer obtains control of the uranium product. The recognition of revenue and related cost of sales occurs at the point in time at which the customer obtains control of SWU or uranium and risk of loss of the product transfers to the customer, which may occur beyond one year. The timing of the transfer of control, subject to notice period requirements, is at the option of the customer. As such, deferred costs and deferred revenue are classified within current assets and current liabilities, respectively. On occasion, the Company will accept payment in the form of uranium. Revenue from the sale of SWU under such contracts is recognized at the time transfer of control of LEU occurs and is based on the fair value of the uranium at contract inception or, as the quantity of uranium is finalized, if variable. Amounts billed to customers for handling costs are included in sales. Handling costs are accounted for as a fulfillment cost and are included in cost of sales. The Company does not have shipping costs associated with outbound freight after control over a product has transferred to a customer. The Company’s contracts with customers do not provide for significant payment terms or financing components. Technical Solutions Revenue The Company generally recognizes revenue for performance obligations to provide services over time based on costs incurred or the right to invoice method (in cases where the value transferred matches the Company’s billing rights), as the customer receives and consumes the benefits. For performance obligations in which control does not continuously transfer to the customer, the Company recognizes revenue at the point in time in which each performance obligation is fully satisfied. This coincides with the point in time the customer obtains control of the product or service, which typically occurs upon customer acceptance or receipt of the product or service, given that the Company maintains control of the product or service until that point. For performance obligation to deliver products with continuous transfer of control to the customer, the Company uses the cost-to-cost input method of progress because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of direct costs incurred to date to the total estimated direct costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Revenue for the Technical Solutions segment, which provides advanced uranium enrichment for the nuclear industry and the U.S. government and advanced manufacturing and other technical services to government and private sector customers is generally recognized over the contractual period as services are rendered. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer. For public sector contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit and assume control of any work in progress. The Company’s government and private sector contracts generally contain contractual termination clauses or entitle the Company to payments for work performed to date for goods and services that do not have an alternative use. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. A contract may contain one or more performance obligations. Two or more promises to transfer goods or services to a customer may be considered a single performance obligation if the goods or services are highly interdependent or highly interrelated such that utility of the promised goods or services to the customer includes integration services provided by the Company. The Company determines the transaction price for each contract based on the consideration it expects to receive for the products or services being provided under the contract. If transaction prices are not stated in the contract for each performance obligation, contractual prices are allocated to performance obligations based on estimated relative standalone selling prices of the promised services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount the Company would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). The Company's contracts with the U.S. government are subject to the FAR and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in the Company’s contracts with the U.S. government are typically equal to the selling price stated in the contract. The Company does not contemplate future modifications, including unexercised options, until they become legally enforceable. Contracts may be subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, the Company considers whether to account for the modification as an adjustment to the existing contract or as a separate contract. Use of the cost-to-cost method requires the Company to make reasonably dependable estimates of costs at completion associated with the design, manufacture and delivery of products and services in order to calculate revenue. Significant judgment is used to estimate total revenue and costs at completion, particularly in the assumptions related to internal labor hours and third-party services for which a vendor invoice or quote is not yet available. As a significant change in one or more estimates could affect the profitability of the Company’s contracts, the Company reviews and updates its contract-related estimates regularly. Adjustments in estimated profits/losses are recognized under the cumulative catch-up method. Under this method, the impact of the adjustments is recognized in the period the adjustment is recognized. When estimates of total costs at completion for such an integrated, construction type contract exceed total estimates of revenue to be earned on a performance obligation related to complex equipment or related services, a provision for the remaining loss on the performance obligation is recognized in the period the loss is determined. The Company applied the practical expedient in paragraph ASC 606-10-50-14 and does not disclose the value of remaining performance obligations under service contracts having original expected terms of one year or less. The timing of revenue recognition may differ from the timing of invoicing to customers. Progress on satisfying performance obligations under contracts with customers and the related billings and cash collections are recorded on the Consolidated Balance Sheet as contract assets or contract liabilities. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. Unbilled receivables are included in Accounts Receivable on the Consolidated Balance Sheet and arise when the timing of cash collected from customers differs from the timing of revenue recognition. In the Technical Solutions segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. These assets are reported on the Consolidated Balance Sheet on a contact-by-contract basis at the end of each reporting period. Those assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. To the extent billings to the customer precede the recognition of Technical Solutions revenue, the Company recognizes a liability included in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet.
Advanced Technology Costs, Policy [Policy Text Block]	Advanced Technology Costs American Centrifuge and related expenses that are outside of the Company’s customer contracts are included in Advanced Technology Costs.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension and Postretirement Health and Life Benefit Plans The Company provides retirement benefits to certain employees and retirees under defined benefit pension plans and a postretirement health and life benefit plan. The valuation of benefit obligations and costs is based on provisions of the plans and actuarial assumptions that involve judgments and estimates. Plan assets and benefit obligations are remeasured each year as of the balance sheet date, or when lump sum payments exceed certain levels, resulting in differences between actual and projected results. The Company has elected to recognize these actuarial gains and losses immediately in the statement of operations to provide transparency regarding the impacts of changes in plan assets and benefit obligations. Executive Severance Plan The Company provides severance benefits to certain covered executives, which may also include continuation of certain insurance benefits, under an Executive Severance Plan (the “Severance Plan”). The benefits payable under the Severance Plan are based on salary level, amongst other variables. As the severance expenses are part of an on-going benefit arrangement, the Company recognizes the expense when payment of the severance is probable and can be reasonably estimated in accordance with ASC 712, Compensation — Nonretirement Postemployment Benefits.
Stock-based Compensation, Policy [Policy Text Block]	Equity-Based Compensation Centrus has an equity-based compensation plan which authorizes the issuance of common stock to the Company’s employees, officers, directors, and other individuals providing services to the Company or its affiliates in the form of stock options, SARs, restricted stock units (“RSU”), restricted stock, notional stock units, performance awards, dividend equivalent rights, and other equity-based awards, as well as cash-based awards. Equity-based compensation cost for options, restricted stock, and other equity-settled awards are measured at the grant date based on the fair value of the award. The cost is recognized over the requisite service period on a straight-line basis over the vesting period. Equity-based compensation cost for awards likely to be settled with cash payments is recognized over the requisite service period and accrued as a liability and re-measured each reporting period based on the trading price of the Company’s common stock. The Company recognizes forfeitures as they occur. New Accounting Standards Recently Adopted Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This pronouncement is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and early adoption is permitted. Based on the Company’s review, it does not have a material impact on its Consolidated Financial Statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes, to improve the transparency of income tax disclosures, primarily through requiring consistent categories and greater disaggregation in the rate reconciliation and requiring disaggregation of income taxes paid by jurisdiction. This pronouncement is effective for fiscal years beginning after December 15, 2024 and early adoption is permitted. Based on the Company’s review, it does not have a material impact on its Consolidated Financial Statements. Accounting Standards Effective in Future Periods In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. This pronouncement is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and early adoption is permitted. The Company is evaluating the impact this will have on its Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832), Accounting for Government Grants Received by Business Entities, to establish authoritative guidance on the accounting for government grants received by business entities. The amendments in this pronouncement establish the accounting for a government grant received by a business entity, including guidance for (1) a grant related to an asset and (2) a grant related to income. A grant related to an asset is a government grant, or part of a government grant, that is conditioned on the purchase, construction, or acquisition of an asset (for example, a long-lived asset or inventory). A grant related to income is a government grant, or part of a government grant, other than a grant related to an asset (for example, a grant that reimburses a business entity for operating expenses). This pronouncement is effective for annual reporting periods beginning after December 15, 2028, and for interim periods within those annual periods, and early adoption is permitted. The Company is evaluating the impact this will have on its Consolidated Financial Statements.

Summary of Significant Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation and Principles of Consolidation

The Consolidated Financial Statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary Enrichment Corp., and its other subsidiaries, were prepared in conformity with U.S. GAAP. Certain prior year amounts have been reclassified for consistency with the current year presentation. All material intercompany transactions have been eliminated.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts presented and disclosed in the Consolidated Financial Statements. Significant estimates and judgments include, but are not limited to, revenue and related costs, asset valuations, pension and postretirement health and life benefit costs and obligations, the tax bases of assets and liabilities, the future recoverability of deferred tax assets, and determination of the valuation allowance for deferred tax assets. Actual results may differ from such estimates, and estimates may change if the underlying conditions or assumptions change.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include short-term or highly liquid assets with original maturities of three months or less.

Inventory, Policy [Policy Text Block]

Inventories and Inventories Owed to Customers and Suppliers

LEU consists of two components: SWU and UF6. SWU is a standard unit of measurement that represents the effort required to transform a given amount of natural uranium into two components: enriched uranium having a higher percentage of U235 and depleted uranium having a lower percentage of U235. The SWU contained in LEU is calculated using an industry standard formula based on the physics of enrichment. The amount of enrichment deemed to be contained in LEU under this formula is commonly referred to as its SWU component and the quantity of UF6 deemed to be used in the production of LEU under this formula is referred to as its uranium or “feed” component.

SWU and uranium inventory costs are determined using the average cost method. SWU and uranium purchase costs include shipping costs when applicable. Inventories of SWU and uranium are valued at the lower of cost or NRV. NRV is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The estimated selling price for SWU and uranium is based on the pricing terms of contracts in the Company’s backlog, and, for uranium not under contract, the estimated selling price is based primarily on published price indicators at the balance sheet date.

Inventories owed to customers and suppliers, included in current liabilities, consist primarily of SWU and uranium inventories owed to fabricators. Fabricators process LEU into fuel for use in nuclear reactors. As delivery obligations under actual customer orders arise, Centrus typically satisfies these obligations by arranging for the transfer to the customer of title to the specified quantity of LEU at the fabricator. Centrus’ balances of SWU and uranium may vary over time based on the timing of customer orders and Centrus’ delivery of LEU. Balances can be positive or negative based on Centrus’ contractual agreements with the fabricators. In cases where the transfer of title of LEU from Centrus to the customer results in quantities of SWU and uranium being owed by Centrus to the fabricator, the amounts of SWU and uranium owed to fabricators are satisfied as future deliveries of LEU to fabricators are made.

Income Tax, Policy [Policy Text Block]

Deferred Taxes

Centrus follows the asset and liability approach to account for deferred taxes. Deferred tax assets and liabilities are recognized for the anticipated future tax consequences of temporary differences between the balance sheet carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are based on income tax rates in effect for the years in which temporary differences are expected to reverse. The effect on deferred taxes of a change in income tax rates is recognized in income when the change in rates is enacted in the law. A valuation allowance is provided if it is more likely than not that all, or some portion, of the deferred tax assets may not be realized.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment

Property, plant and equipment are recorded at acquisition cost. Leasehold improvements and machinery and equipment are depreciated on a straight-line basis over the shorter of the useful life of the assets or the lease term, if applicable. Refer also to Carrying Value of Long-Lived Assets below.

Intangible Assets, Policy [Policy Text Block]

Intangible Assets

Centrus has intangible assets resulting from fresh start accounting as a result of emergence from Chapter 11 bankruptcy on September 30, 2014. The identifiable intangible assets relate to the sales backlog and customer relationships. The backlog intangible asset is amortized as the backlog valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized using the straight-line method over the estimated average useful life of 15 years, with 3 ¾ years of scheduled amortization remaining. Refer also to Carrying Value of Long-Lived Assets below.

Carrying Value of Long-Lived Assets

The Company evaluates the carrying values of property, plant and equipment and identifiable intangible assets when events or changes in business circumstances indicate that the carrying amount of asset, or asset group, may not be fully recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset, or asset group, exceeds its fair value.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Financial Instruments and Fair Value Measurement

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, consideration is given to the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability.

Pursuant to accounting standards, Centrus’ 0% Convertible Notes due August 2032 and 2.25% Convertible Notes due November 2030 are recorded at face value and carrying value respectively, and the fair value is disclosed. Centrus’ 8.25% Notes due February 2027 were recorded at face value and carrying value respectively, and the fair value as of December 31, 2024 is disclosed. The 8.25% Notes were redeemed on March 26, 2025. The estimated fair value of the 0% Convertible Notes, 2.25% Convertible Notes and 8.25% Notes are based on bid/ask quotes as of or near the balance sheet date. Debt issuance costs are deferred and amortized over the life of the instrument.

The balance sheet carrying amounts for accounts receivable, accounts payable and accrued liabilities, and payables under inventory purchase agreements approximate fair value because of the short-term nature of the instruments.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Credit Risk

Credit risk could result from the possibility of a customer failing to perform or pay according to the terms of a contract. Extension of credit is based on an evaluation of each customer’s financial condition. Centrus regularly monitors credit risk exposure and takes steps intended to mitigate the likelihood of such exposure resulting in a loss.

Segment Reporting, Policy [Policy Text Block]

Segments

Centrus operates two business segments: LEU, which supplies various components of nuclear fuel to commercial customers from our global network of suppliers, and Technical Solutions, which provides advanced uranium enrichment for the nuclear industry and the U.S. government and advanced manufacturing and other technical services to government and private sector customers and advanced uranium enrichment for the nuclear industry and the U.S. government.

Revenue Recognition, Policy

Revenue

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue for product and service sales is recognized when or as the Company transfers control of the promised products or services to the customer. Revenue is measured at the transaction price, which is based on the amount of consideration that the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price will include estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur.

SWU and Uranium Revenue

Revenue for the Company’s LEU segment is derived from sales of the SWU component of LEU, sales of both the SWU and uranium components of LEU, sales of conversion credits, and sales of UF6 and U3O8. Contracts with customers are primarily medium and long-term, fixed-commitment, contracts under which its customers are obligated to purchase a specified quantity of the SWU component of LEU or the SWU and uranium components of LEU. The Company’s contracts for UF6 and U3O8 are generally shorter-term, fixed-commitment contracts.

Revenue is recognized at the time the customer obtains control of the LEU or uranium. Customers generally obtain control of LEU at nuclear fuel fabricators. Centrus ships LEU to nuclear fuel fabricators for scheduled or anticipated orders from utility customers. Based on customer orders, Centrus arranges for the transfer of title of LEU from Centrus to the customer for the specified quantity of LEU at the fuel fabricator. Each such delivery to a customer is accounted for as a distinct performance obligation under a contract, and a contract may call for multiple deliveries over a number of periods. The contract’s transaction price is allocated to each performance obligation based on the observable standalone selling price of each distinct delivery of SWU or uranium. For certain contracts the customers may elect not to take control of the LEU or uranium and Centrus may have the right to enforce payment under the terms of the contractual agreement. The revenue recognition for these contracts is assessed when it occurs.

Utility customers in general have the option to defer receipt of uranium products purchased from the Company beyond the contractual sale period. In such cases, title to SWU and/or uranium components are transferred to the customer and a performance obligation for Centrus is created and a receivable is recorded. Cash is collected for the receivable under normal credit terms. The performance obligation is represented as deferred revenue in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet and the customer-titled product is classified as Deferred Costs Associated with Deferred Revenue on the Consolidated Balance Sheet. Risk of loss remains with Centrus until the customer obtains control of the uranium product. The recognition of revenue and related cost of sales occurs at the point in time at which the customer obtains control of SWU or uranium and risk of loss of the product transfers to the customer, which may occur beyond one year. The timing of the transfer of control, subject to notice period requirements, is at the option of the customer. As such, deferred costs and deferred revenue are classified within current assets and current liabilities, respectively.

On occasion, the Company will accept payment in the form of uranium. Revenue from the sale of SWU under such contracts is recognized at the time transfer of control of LEU occurs and is based on the fair value of the uranium at contract inception or, as the quantity of uranium is finalized, if variable.

Amounts billed to customers for handling costs are included in sales. Handling costs are accounted for as a fulfillment cost and are included in cost of sales. The Company does not have shipping costs associated with outbound freight after control over a product has transferred to a customer. The Company’s contracts with customers do not provide for significant payment terms or financing components.

Technical Solutions Revenue

The Company generally recognizes revenue for performance obligations to provide services over time based on costs incurred or the right to invoice method (in cases where the value transferred matches the Company’s billing rights), as the customer receives and consumes the benefits. For performance obligations in which control does not continuously transfer to the customer, the Company recognizes revenue at the point in time in which each performance obligation is fully satisfied. This coincides with the point in time the customer obtains control of the product or service, which typically occurs upon customer acceptance or receipt of the product or service, given that the Company maintains control of the product or service until that point.

For performance obligation to deliver products with continuous transfer of control to the customer, the Company uses the cost-to-cost input method of progress because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of direct costs incurred to date to the total estimated direct costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

Revenue for the Technical Solutions segment, which provides advanced uranium enrichment for the nuclear industry and the U.S. government and advanced manufacturing and other technical services to government and private sector customers is generally recognized over the contractual period as services are rendered. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer. For public sector contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit and assume control of any work in progress. The Company’s government and private sector contracts generally contain contractual termination clauses or entitle the Company to payments for work performed to date for goods and services that do not have an alternative use. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. A contract may contain one or more performance obligations. Two or more promises to transfer goods or services to a customer may be considered a single performance obligation if the goods or services are highly interdependent or highly interrelated such that utility of the promised goods or services to the customer includes integration services provided by the Company.

The Company determines the transaction price for each contract based on the consideration it expects to receive for the products or services being provided under the contract. If transaction prices are not stated in the contract for each performance obligation, contractual prices are allocated to performance obligations based on estimated relative standalone selling prices of the promised services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount the Company would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). The Company's contracts with the U.S. government are subject to the FAR and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in the Company’s contracts with the U.S. government are typically equal to the selling price stated in the contract. The Company does not contemplate future modifications, including unexercised options, until they become legally enforceable. Contracts may be subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, the Company considers whether to account for the modification as an adjustment to the existing contract or as a separate contract.

Use of the cost-to-cost method requires the Company to make reasonably dependable estimates of costs at completion associated with the design, manufacture and delivery of products and services in order to calculate revenue. Significant judgment is used to estimate total revenue and costs at completion, particularly in the assumptions related to internal labor hours and third-party services for which a vendor invoice or quote is not yet available. As a significant change in one or more estimates could affect the profitability of the Company’s contracts, the Company reviews and updates its contract-related estimates regularly. Adjustments in estimated profits/losses are recognized under the cumulative catch-up method. Under this method, the impact of the adjustments is recognized in the period the adjustment is recognized. When estimates of total costs at completion for such an integrated, construction type contract exceed total estimates of revenue to be earned on a performance obligation related to complex equipment or related services, a provision for the remaining loss on the performance obligation is recognized in the period the loss is determined.

The Company applied the practical expedient in paragraph ASC 606-10-50-14 and does not disclose the value of remaining performance obligations under service contracts having original expected terms of one year or less.

The timing of revenue recognition may differ from the timing of invoicing to customers. Progress on satisfying performance obligations under contracts with customers and the related billings and cash collections are recorded on the Consolidated Balance Sheet as contract assets or contract liabilities. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period.

Unbilled receivables are included in Accounts Receivable on the Consolidated Balance Sheet and arise when the timing of cash collected from customers differs from the timing of revenue recognition. In the Technical Solutions segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. These assets are reported on the Consolidated Balance Sheet on a contact-by-contract basis at the end of each reporting period. Those assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. To the extent billings to the customer precede the recognition of Technical Solutions revenue, the Company recognizes a liability included in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet.

Advanced Technology Costs, Policy [Policy Text Block]

Advanced Technology Costs

American Centrifuge and related expenses that are outside of the Company’s customer contracts are included in Advanced Technology Costs.

Pension and Other Postretirement Plans, Policy [Policy Text Block]

Pension and Postretirement Health and Life Benefit Plans

The Company provides retirement benefits to certain employees and retirees under defined benefit pension plans and a postretirement health and life benefit plan. The valuation of benefit obligations and costs is based on provisions of the plans and actuarial assumptions that involve judgments and estimates. Plan assets and benefit obligations are remeasured each year as of the balance sheet date, or when lump sum payments exceed certain levels, resulting in differences between actual and projected results. The Company has elected to recognize these actuarial gains and losses immediately in the statement of operations to provide transparency regarding the impacts of changes in plan assets and benefit obligations.

Executive Severance Plan

The Company provides severance benefits to certain covered executives, which may also include continuation of certain insurance benefits, under an Executive Severance Plan (the “Severance Plan”). The benefits payable under the Severance Plan are based on salary level, amongst other variables. As the severance expenses are part of an on-going benefit arrangement, the Company recognizes the expense when payment of the severance is probable and can be reasonably estimated in accordance with ASC 712, Compensation — Nonretirement Postemployment Benefits.

Stock-based Compensation, Policy [Policy Text Block]

Equity-Based Compensation

Centrus has an equity-based compensation plan which authorizes the issuance of common stock to the Company’s employees, officers, directors, and other individuals providing services to the Company or its affiliates in the form of stock options, SARs, restricted stock units (“RSU”), restricted stock, notional stock units, performance awards, dividend equivalent rights, and other equity-based awards, as well as cash-based awards.

Equity-based compensation cost for options, restricted stock, and other equity-settled awards are measured at the grant date based on the fair value of the award. The cost is recognized over the requisite service period on a straight-line basis over the vesting period.

Equity-based compensation cost for awards likely to be settled with cash payments is recognized over the requisite service period and accrued as a liability and re-measured each reporting period based on the trading price of the Company’s common stock.

The Company recognizes forfeitures as they occur.

New Accounting Standards

Recently Adopted Accounting Standards

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This pronouncement is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and early adoption is permitted. Based on the Company’s review, it does not have a material impact on its Consolidated Financial Statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes, to improve the transparency of income tax disclosures, primarily through requiring consistent categories and greater disaggregation in the rate reconciliation and requiring disaggregation of income taxes paid by jurisdiction. This pronouncement is effective for fiscal years beginning after December 15, 2024 and early adoption is permitted. Based on the Company’s review, it does not have a material impact on its Consolidated Financial Statements.

Accounting Standards Effective in Future Periods

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. This pronouncement is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and early adoption is permitted. The Company is evaluating the impact this will have on its Consolidated Financial Statements.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832), Accounting for Government Grants Received by Business Entities, to establish authoritative guidance on the accounting for government grants received by business entities. The amendments in this pronouncement establish the accounting for a government grant received by a business entity, including guidance for (1) a grant related to an asset and (2) a grant related to income. A grant related to an asset is a government grant, or part of a government grant, that is conditioned on the purchase, construction, or acquisition of an asset (for example, a long-lived asset or inventory). A grant related to income is a government grant, or part of a government grant, other than a grant related to an asset (for example, a grant that reimburses a business entity for operating expenses). This pronouncement is effective for annual reporting periods beginning after December 15, 2028, and for interim periods within those annual periods, and early adoption is permitted. The Company is evaluating the impact this will have on its Consolidated Financial Statements.
