Century Aluminum Company reported strong second quarter 2026 results for the quarter ended June 30, 2026. Net sales were $752.1 million, an increase of $102.9 million sequentially, driven by higher realized metal prices and aluminum shipments rising to 130,632 tonnes following the Mt. Holly expansion and the restart of Line 2 at Grundartangi.
Net income attributable to Century was $249.3 million, down $88.2 million sequentially due mainly to a prior-quarter $287.9 million gain on the sale of Hawesville. After adjusting for one-time and exceptional items, adjusted net income attributable to Century rose to $257.3 million, an $86.6 million sequential increase, and adjusted EBITDA attributable to Century grew by $95.5 million to $326.9 million, reflecting favorable metal and power prices and improved operating performance.
Liquidity at June 30, 2026 was $784.9 million, including cash and cash equivalents of $343.4 million, restricted cash of $44.8 million and $396.7 million of borrowing availability; by the end of July, cash exceeded total debt. Business highlights included completing the restart of the last 90 pots at Mt. Holly, returning Grundartangi Line 2 to near full production, and receiving a $94.3 million Section 45X refund in July. For the third quarter of 2026, the company expects adjusted EBITDA attributable to Century between $325 million and $345 million.
Century Aluminum Company reported the results of its 2026 Annual Meeting of Stockholders held on June 15, 2026. A quorum was reached, with 85,513,459 shares of common stock present or represented by proxy, representing approximately 86.39% of shares outstanding and entitled to vote.
Stockholders elected seven directors – Jarl Berntzen, Jennifer Bush, Jesse Gary, Errol Glasser, Wilhelm van Jaarsveld, Andrew Michelmore, and Tamla Olivier – each to a one-year term expiring at the 2027 annual meeting. They also ratified the appointment of Deloitte & Touche LLP as the independent registered public accounting firm for the year ending December 31, 2026.
In addition, stockholders approved, on a non-binding advisory basis, the compensation of the company’s named executive officers as described in the proxy statement, indicating support for the company’s current executive pay program.
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.
Century Aluminum Company is changing how it accounts for its 55% interest in the Jamalco joint venture, moving from proportionate consolidation to fully consolidating the Jamalco production assets with higher noncontrolling interest. This change follows SEC staff comment letters on prior filings.
The company determined this accounting change is material and concluded that its previously issued consolidated financial statements for 2023, 2024 and several interim periods should no longer be relied upon and will be restated. The change increases total assets and total equity, while gross profit is reduced by less than 10% in each affected period, but net income attributable to Century stockholders and total stockholders’ equity are unchanged.
Century Aluminum expects to report a material weakness in internal control over financial reporting in connection with these restatements. The impacts and corrected figures are to be reflected in its 2025 Form 10-K, and recent Q4 2025 unaudited results already incorporate the new accounting.
Century Aluminum Company reported fourth quarter 2025 net sales of $633.7 million and net income attributable to stockholders of $1.8 million, or $0.02 per diluted share. Adjusted net income was much higher at $128.2 million, or $1.25 per share, with Adjusted EBITDA of $170.6 million.
For full year 2025, net sales reached $2.5 billion and net income attributable to stockholders was $41.8 million, or $0.42 per diluted share. Adjusted net income rose to $253.8 million and Adjusted EBITDA to $425.1 million, both improving significantly from 2024 despite equipment failure in Iceland, hurricane impacts at Jamalco and restart costs at Mt. Holly. Liquidity at December 31, 2025 totaled $418.0 million, including cash of $134.2 million. The company highlighted a joint development agreement with Emirates Global Aluminium for a new U.S. smelter, the sale and redevelopment of the Hawesville site, a planned Mt. Holly restart, and guided first quarter 2026 Adjusted EBITDA to $215–$235 million.
