Century Aluminum Co. filings document the regulatory record of a Nasdaq-listed primary aluminum producer, including earnings-related Form 8-K reports, annual meeting proxy materials and material-event disclosures. The filings cover operating results, aluminum shipments, liquidity, non-GAAP measures, common stock registration details and governance matters presented to shareholders.
Recent disclosures also address accounting treatment for the Jamalco Production Assets, related non-reliance and late-filing notices, and material agreements involving subsidiary asset sales. The filing record ties these items to Century's aluminum operations, consolidation policies, board oversight, capital structure and public-company reporting obligations.
Century Aluminum reported a sharp turnaround in Q1 2026, earning net income of $327.0 million, up from $22.4 million a year earlier. Net sales edged up to $649.2 million from $633.9 million, helped by higher London Metal Exchange prices and much stronger U.S. regional premiums.
Results were boosted by a $287.9 million gain on the sale of the idled Hawesville smelter and a $33.0 million gain on insurance proceeds tied to the Grundartangi transformer failure, partly offset by a $65.3 million net loss on derivatives. Basic EPS rose to $3.41 from $0.30.
Cash, cash equivalents and restricted cash increased to $333.6 million from $135.6 million at year-end, aided by $200.0 million Hawesville sale proceeds, while total debt was stable at $545.9 million, including 2.75% convertible notes due 2028 and 6.875% senior secured notes due 2032. Century also benefits from Section 45X production tax credits, which reduced Q1 2026 cost of goods sold and SG&A by $25.7 million.
Century Aluminum Company reported a sharply stronger first quarter 2026, driven by a major asset sale and better underlying performance. Net sales were $649.2 million, up $15.5 million from Q4 2025, as higher realized aluminum prices more than offset lower shipments.
Net income attributable to Century jumped to $337.5 million, or $3.23 diluted EPS, versus $0.02 in the prior quarter, largely due to a $287.9 million gain on the sale of Hawesville and a $33.0 million gain on Iceland insurance proceeds. Adjusted net income rose to $170.7 million and adjusted EPS to $1.63, while adjusted EBITDA attributable to Century increased to $231.4 million from $170.6 million. Liquidity was $611.0 million as of March 31, 2026, and the company expects Q2 2026 adjusted EBITDA between $315 million and $335 million.
