Notes:
(1) Non-GAAP measure; see reconciliation of GAAP to non-GAAP financial measures.

Century reported net income attributable to Century stockholders of $47.7 million for the fourth quarter of 2024, a $0.4 million improvement sequentially primarily attributed to a nonrecurring benefit from a force majeure settlement, recovery from Hurricane Beryl, and improved realized metal prices and regional premiums offset by the one-time IRA 45X adjustment for final regulations published in the third quarter. Fourth quarter results were impacted by $0.7 million of net exceptional items, in particular $5.8 million of unrealized losses on forward derivative contracts (net of tax), more than offset by $5.3 million in share-based compensation costs and $2.0 million of lower cost or net realizable value inventory adjustment (net of tax). Thus, Century reported an adjusted net income of $45.9 million for the fourth quarter of 2024, a $14.1 million change sequentially.

Century reported net income attributable to Century stockholders of $339.4 million for the full year 2024, a $382.5 million improvement from the full year 2023. Full year 2024 results were impacted by $217.5 million of exceptional items, in particular recognition of the bargain purchase gain from the Jamalco acquisition of $245.9 million, $5.5 million of net losses on forward derivative contracts (net of tax), $6.4 million lower of cost or net realizable value inventory adjustment (net of tax), partially offset by $15.5 million in share-based compensation costs, $4.7 million related to the power equipment failure at Jamalco and $6.9 million related to the hurricane impact at Jamalco. Thus, Century reported an adjusted net income of $104.0 million, a $73.3 million improvement from the full year 2023.

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.
