Business Highlights

Net sales of $649.2 million increased sequentially
Achieved adjusted EBITDA attributable to Century of $231.4 million
Received insurance proceeds totaling $83 million to date related to Iceland equipment failure
Initiated expansion of last 90 pots at Mt. Holly and restart of Line 2 at Grundartangi in April 2026

Net sales for the first quarter ended March 31, 2026 increased by $15.5 million sequentially primarily driven by an increase in realized metal prices, despite lower shipments following the first full quarter of Iceland line 2 equipment failure in late October 2025 and lower third-party alumina sales.

Century reported Net income attributable to Century of $337.5 million for the first quarter of 2026, a $335.7 million increase sequentially. The increase in net earnings during the first quarter of 2026 was primarily attributable to a one-time gain on sale of Hawesville of $287.9 million, a gain on insurance proceeds related to Iceland equipment failure of $33.0 million, favorable realized LME and regional premium prices, partially offset by unfavorable power price realization due to extreme winter weather in the United States and unfavorable raw material price realization.

First quarter results were also impacted by $166.8 million of net exceptional items, in particular, the gains described above; $48.1 million of unrealized losses on derivative instruments, net of tax; $60.0 million related to equipment failures in Iceland, net of tax; $5.9 million related to the impact of Hurricane Melissa on Jamalco's operations; $13.3 million in emergency energy charges related to extreme winter weather at Mt. Holly; $9.4 million of share-based compensation; Mt. Holly expansion project expenses of $7.5 million and Hawesville inventory write-down of $3.3 million. Therefore, Century reported an Adjusted net income attributable to Century of $170.7 million for the first quarter of 2026, a $42.5 million increase sequentially.

Adjusted EBITDA attributable to Century for the first quarter of 2026 was $231.4 million. This was an increase of $60.8 million from the prior quarter, mainly from favorable realized metal prices, sales mix and operating expenses, partially offset by unfavorable power price and raw material price realization.

Century's liquidity position at March 31, 2026 was $611.0 million, comprised of cash and cash equivalents of $244.1 million, restricted cash proceeds from the sale of Hawesville of $88.1 million, and $278.8 million in combined borrowing availability.

Second Quarter 2026 Outlook

The Company expects second quarter Adjusted EBITDA to range between $315 to $335 million primarily driven by higher realized LME and regional premiums and the expansion at Mt. Holly.

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.
