Business Highlights

Completed restart of last 90 pots at Mt. Holly
Returned Line 2 at Grundartangi to near full production
New Jamalco power generation turbine (TG4) online in August
Received 2025 45X refund totaling $94.3 million in July
As of the end of July, Century cash exceeded total debt
Net sales for the second quarter ended June 30, 2026 increased by $102.9 million sequentially primarily driven by an increase in realized metal prices and higher shipments attributable to increased production from the Mt. Holly expansion and restart of Line 2 at Grundartangi during the quarter.
Century reported Net income attributable to Century of $249.3 million for the second quarter of 2026, a $88.2 million decrease sequentially. The decrease in net earnings during the second quarter of 2026 was primarily attributable to the one-time gain on sale of Hawesville of $287.9 million in the first quarter, offset by favorable realized LME and regional premium prices, and an increase in gain on insurance proceeds related to Iceland equipment failure of $7.1 million and favorable power price realization due to improved weather conditions in the United States, partially offset by unfavorable raw material price realization.
Second quarter results were also impacted by $8.0 million of net exceptional items, in particular, $61.3 million related to equipment failures in Iceland, net of tax; $38.9 million of unrealized gains on derivative instruments, net of tax; $2.5 million of share-based compensation and Mt. Holly expansion project expenses of $10.7 million. Therefore, Century reported an Adjusted net income attributable to Century of $257.3 million for the second quarter of 2026, a $86.6 million increase sequentially.
Adjusted EBITDA attributable to Century for the second quarter of 2026 was $326.9 million. This was an increase of $95.5 million from the prior quarter, mainly from favorable realized metal prices, sales mix and operating expenses, favorable power price, partially offset by unfavorable raw material price realization.
Century's liquidity position at June 30, 2026 was $784.9 million, comprised of cash and cash equivalents of $343.4 million, restricted cash of $44.8 million, and $396.7 million in combined borrowing availability.
Third Quarter 2026 Outlook
The Company expects third quarter Adjusted EBITDA attributable to Century to range between $325 million to $345 million.

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.
