Century Aluminum Company files a comprehensive annual report that restates prior financial statements after changing how it consolidates its 55% Jamalco joint venture; the restatement does not change net income attributable to Century stockholders. The company reports 2025 aluminum production of 638,000 tonnes versus 770,000 tonnes of capacity and discloses an adverse opinion on internal control over financial reporting.
Century highlights a new joint development agreement with Emirates Global Aluminium to build a 750,000‑tonne‑per‑year primary aluminum smelter in Inola, Oklahoma, where Century will own 40%. It also completed the $200 million sale of its idled Hawesville, Kentucky site for cash and a 6.8% minority interest in a planned data center project, and notes a transformer failure that has temporarily cut output at its Grundartangi, Iceland smelter by about two‑thirds. Customer concentration remains high, with Glencore accounting for 54% of 2025 sales and owning 36.4% of Century’s common stock.
