Deferred Taxes

Future tax consequences of temporary differences between the carrying amounts for financial reporting purposes and the Company’s estimate of the tax bases of its assets and liabilities result in deferred tax assets and liabilities, as follows (in millions):

The valuation allowance reduces the net deferred tax assets to their net realizable value. The ultimate realization of the net deferred tax assets is dependent upon generating sufficient taxable income in future years when deferred tax assets are recoverable or are expected to reverse.

In 2025, Centrus evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus has visibility on a significant portion of revenue in the LEU segment for 2025 through 2030, primarily from its long-term sales contracts. Additionally, Centrus’ investment income forecast increased based upon increased liquidity. Centrus determined that the positive evidence of increased future investment income supported the release of the federal valuation allowance. However, because of the lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus released ($10.2) million of the valuation allowance against its federal net deferred tax assets.
In 2024, the Company evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus had visibility on a significant portion of revenue in the LEU segment for 2025 through 2026, primarily from its long-term sales contracts. Additionally, Centrus’ interest income forecast increased based upon increased liquidity. Centrus determined that the positive evidence of increased forecasted future income in the LEU segment based on existing sales backlog and supply contracts along with commodity market forward pricing indicators, and interest outlook supported the release of the federal valuation allowance. However, because of the lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus released ($16.6) million of the valuation allowance against its federal net deferred tax assets.

In 2023, the Company evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus had visibility on a significant portion of revenue in the LEU segment for 2024 through 2026, primarily from its long-term sales contracts. Centrus determined that the positive evidence of increased forecasted future income in the LEU segment based on existing sales backlog and supply contracts along with commodity market forward pricing indicators, supported the release of the federal valuation allowance. However, because of the lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus recorded a partial release of its federal valuation allowance. In the third and fourth quarters of 2023, respectively, Centrus released ($7.7) million and ($11.7) million of the valuation allowance against its federal net deferred tax assets.

The Company continues to maintain a partial valuation allowance against its remaining federal and state net deferred tax assets due to significant federal and state net operating losses and insufficient future taxable income. As of December 31, 2025, the valuation allowance against the remaining federal and state net deferred tax assets was $355.4 million.

Going forward, Centrus will continue to evaluate both positive and negative evidence that would support any further changes to the remaining federal and state valuation allowances. Such evidence in the Company’s Technical Solutions segment may include events that could have a significant impact on pre-tax income, such as signing new contracts with significantly higher or lower margins than currently forecasted, follow-on work related to the HALEU program, or abandonment of the commercial deployment of the centrifuge technology. Such evidence in our LEU segment may include renewing SWU sales contracts with existing customers and/or signing new SWU sales or purchase contracts with significantly higher or lower margins than currently forecasted. Additional evidence in the LEU segment may include potential deferrals in the timing of deliveries requested by its customers, which could impact revenue recognition timing. The impact of these and other potential positive and negative events will be weighed and evaluated to determine if the valuation allowances should be increased or decreased in the future.

The Company has federal NOLs of $505.2 million remaining, which were generated through December 31, 2017. They currently expire through 2037. In addition, the Company has federal NOL carryforwards of $131.4 million generated after December 31, 2017, that do not expire. Centrus also has state NOL carryforwards of $491.3 million, with a full valuation allowance, that currently expire through 2038.

(1) State Taxes in Maryland (greater than 50 percent) of the tax effect in this category for the calendar year ending December 31, 2025.

The effective tax rate for the year ended December 31, 2025, includes a decrease to the valuation allowance against net deferred tax assets of $10.2 million, or a change to the effective tax rate of (12%).

The effective tax rate for the year ended December 31, 2024, includes a decrease to the valuation allowance against net deferred tax assets of $16.6 million, or a change to the effective tax rate of (23%).

The effective tax rate for the year ended December 31, 2023, includes a decrease to the valuation allowance against net deferred tax assets of $31.7 million, or a change to the effective tax rate of (38%). Included in the valuation allowance decrease is the release of the valuation allowance against federal net deferred taxes of $19.4 million, or a change to the effective tax rate of (23%), as well as a release of the valuation allowance against state net deferred taxes for state rate changes of $12.3 million during the year, as a result of state law changes, or a change to the effective tax rate of (15%). There is an offsetting increase to the effective tax rate for state rate changes of $12.1 million, or a change to the effective tax rate of 15% so that the impact for the state rate changes net of the corresponding valuation allowance decrease is zero.

Uncertain Tax Positions

Accounting standards require that a tax position meet a minimum recognition threshold in order for the related tax benefit to be recognized in the financial statements. The liability for unrecognized tax benefits, included in Other Long-Term Liabilities, was $3.6 million as of December 31, 2025, and $3.4 million as of December 31, 2024. If recognized, these tax benefits would impact the effective tax rate. As a result of changes to unrecognized tax benefits, the income tax provision (state tax, net of federal benefit) increased by $0.2 million and $0.5 million during the year ended December 31, 2025 and 2024, respectively. The liability for unrecognized tax benefits in the table below relates to unrecognized state income tax benefits.
A reconciliation of the beginning and ending amount of unrecognized tax benefits follows (in millions):

Centrus and its subsidiaries file income tax returns with the U.S. government and various states and foreign jurisdictions. As of December 31, 2025, the federal, Maryland and Tennessee statutes of limitation are closed with respect to all tax years through 2021.

Centrus recognizes accrued interest related to uncertain tax positions as a component of Interest Expense. Reversals of previously accrued interest for income taxes is typically offset against interest expense, but if the amount is significant, it is reclassified to interest income in the Consolidated Statements of Operations. Centrus recognizes the increase or decrease of accrued penalties for income taxes as a component of Selling, General and Administrative in the Consolidated Statements of Operations.

The impact of accrued interest and penalties for income taxes in the Consolidated Statements of Operations was an increase to expenses of $0.3 million for the year ended December 31, 2025, and $0.3 million for the year ended December 31, 2024. Accrued interest and penalties for income taxes, included as a component of Other Long-Term Liabilities, totaled $0.8 million as of December 31, 2025, and $0.5 million as of December 31, 2024.
