In the fourth quarter of 2025, shipments of primary aluminum decreased 14% sequentially, attributable to idled production at our Iceland facility due to equipment failure. Net sales for the fourth quarter of 2025 increased marginally due to higher aluminum prices and increased regional premiums.

Century reported net income attributable to Century stockholders of $1.8 million for the fourth quarter of 2025, a $13.1 million decrease sequentially primarily due to the Iceland equipment failure and costs related to recovery from Hurricane Melissa. Fourth quarter results were impacted by $126.4 million of net exceptional items, in particular $30.9 million (net of tax) related to our Iceland equipment failure, $32.6 million in share-based compensation costs, $27.6 million of unrealized losses on forward derivative contracts, $5.7 million related to the hurricane impact at Jamalco, Hawesville inventory write-down of $9.9 million, Mt. Holly restart project costs of $8.0 million and $9.8 million of lower cost or net realizable value inventory adjustment. Thus, Century reported an Adjusted net income attributable to Century stockholders of $128.2 million for the fourth quarter of 2025, a $70.3 million improvement sequentially.

Adjusted EBITDA attributable to Century stockholders for the fourth quarter of 2025 was $170.6 million. This was a sequential improvement of $69.5 million. Adjusted EBITDA improved primarily driven by favorable realized LME and regional price premiums and improved operating costs and increased volume attributable to Mt. Holly over prior quarter.

Century's liquidity position at December 31, 2025, comprised of cash and cash equivalents of $134.2 million and $283.8 million in combined borrowing availability, was $418.0 million.

For the full year 2025, shipments of primary aluminum decreased by 5% sequentially. Net sales for the full year 2025 increased by $307.6 million sequentially, primarily due to higher realized aluminum prices.

Century reported net income attributable to Century stockholders of $41.8 million for the full year 2025, a $295.0 million decrease from the full year 2024. Full year 2025 results were impacted by $213.8 million of exceptional items, in particular $62.8 million of net losses on forward derivative contracts, partially offset by $47.0 million in share-based compensation costs, $37.3 million (net of tax) related to our Iceland equipment failure, $5.7 million related to the hurricane impact at Jamalco, Hawesville inventory write-down of $9.9 million, Mt. Holly restart project costs of $8.5 million and $10.5 million lower of cost or net realizable value inventory adjustment. Thus, Century reported an Adjusted net income attributable to Century stockholders of $253.8 million for the full year 2025, a $152.4 million improvement from the full year 2024.

Adjusted EBITDA attributable to Century stockholders for the full year 2025 was $425.1 million, an improvement of $180.9 million compared to the prior year, primarily driven by higher realized aluminum prices and regional premiums.

First Quarter 2026 Outlook

The Company expects first quarter Adjusted EBITDA attributable to Century stockholders to range between $215 to $235 million based on improved metal pricing and regional premiums, partially offset by temporary higher energy costs in the United States as a result of Winter Storm Fern.

Non-GAAP Financial Measures

Adjusted net income (loss), Adjusted earnings (loss) per share and Adjusted EBITDA are non-GAAP financial measures that management uses to evaluate Century's financial performance. These non-GAAP financial measures facilitate comparisons of this period's results with prior periods on a consistent basis by excluding items that management does not believe are indicative of Century's ongoing operating performance and ability to generate cash. Management believes these non-GAAP financial measures enhance an overall understanding of Century's performance and our investors' ability to review Century's business from the same perspective as management. The tables below, under the heading "Reconciliation of Non-GAAP Financial Measures," provide a reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, Century's reported results prepared in accordance with GAAP. In addition, because not all companies use identical calculations, Adjusted net income (loss), Adjusted earnings (loss) per share and Adjusted EBITDA included in this press release may not be comparable to similarly titled measures of other companies. Investors are encouraged to review the reconciliations in conjunction with the presentation of these non-GAAP financial measures. We do not provide a reconciliation of forward-looking Adjusted EBITDA because the corresponding forward-looking GAAP financial measures is not currently available and management cannot reliably predict all the necessary components of such forward-looking GAAP measures without unreasonable effort or expense due to the inherent difficulty of forecasting and quantifying certain amounts that are necessary for such a reconciliation, including adjustments that could be made for restructuring, the variability of our tax rate, the impact of foreign currency fluctuation, and other charges reflected in our historical results. The probable significance of each of these items is high and, based on historical experience, could be material.
