Income Taxes

5.    Income Taxes

For the three months ended March 31, 2026 and 2025, we recorded an income tax expense of $1.8 million and $1.6 million, respectively. The change is primarily due to changes in pretax income amounts and jurisdictional mix on a year over year basis.

Our income tax expense or benefit for interim periods is determined using an estimate of our annual effective tax rate ("AETR"), adjusted for discrete items. In February 2026, the Company completed the sale of Hawesville. The sale was determined to be a discrete item that is not part of the Company’s ordinary operations and, accordingly, the related tax effects were excluded from the computation of the estimated AETR. The application of the accounting requirements for income taxes in interim periods, after consideration of our valuation allowance on domestic losses, causes a significant variation in the typical relationship between income tax expense/benefit and pretax accounting income/loss as reported on the Consolidated Statements of Operations.

As of March 31, 2026, all of Century's U.S. and certain foreign deferred tax assets, net of deferred tax liabilities, continue to be subject to a full valuation allowance.

Section 45X of the Inflation Reduction Act of 2022 ("IRA") contains a production tax credit equal to 10% of certain eligible production costs, including, without limitation, labor, energy, depreciation and amortization and overhead expenses. On October 24, 2024, the U.S. Department of the Treasury and the Internal Revenue Service issued final regulations on the production tax credit requirements under Internal Revenue Code Section 45X (the "IRA Regulations"). The IRA Regulations provide guidance on rules that taxpayers must satisfy to qualify for the IRA Section 45X tax credit. For the three months ended March 31, 2026 and 2025, the Company recognized a reduction of $25.0 million and $19.9 million in Cost of goods sold and a reduction of $0.7 million and $0.8 million in Selling, general and administrative expenses, respectively, within the Consolidated Statements of Operations.
