In the fourth quarter of 2023, shipments of primary aluminum increased 1% sequentially. Net sales for the fourth quarter of 2023 decreased by 6% sequentially due to lower realized aluminum prices.

Century reported net income attributable to Century stockholders of $30.0 million for the fourth quarter of 2023, a $72.0 million improvement sequentially primarily attributed to the recognition of the full year Inflation Reduction Act Advanced Manufacturing credit in the period and the change in net income (loss) provided by forward and derivative contracts, partially offset by the change from recognized income tax benefit to income tax expense. Fourth quarter results were impacted by $9.2 million of net exceptional items, in particular $7.4 million related to the power equipment failure at Jamalco, $2.9

million of unrealized losses on forward derivative contracts (net of tax) and $1.3 million increase in share-based compensation costs driven by market inputs, partially offset by $3.0 million of lower cost or net realizable value adjustment (net of tax). Thus, Century reported an adjusted net income of $40.0 million for the fourth quarter of 2023, a $53.8 million improvement sequentially.

Adjusted EBITDA attributable to Century stockholders for the fourth quarter of 2023 was $57.1 million. This was an improvement of $47.8 million from the third quarter as a result of the recognition of the Inflation Reduction Act Advanced Manufacturing credit in the period, partially offset by additional operating expenses in the period and lower realized aluminum prices sequentially.

Century's liquidity position at December 31, 2023, comprised of cash and cash equivalents of $88.8 million and $223.7 million in combined borrowing availability, was $312.5 million, an increase of $6.7 million from the third quarter of 2023.

For the full year 2023, shipments of primary aluminum decreased by 9% sequentially. Net sales for the full year 2023 decreased by $591.9 million sequentially, primarily due to lower realized aluminum prices in addition to the lower volume of shipments.

Century reported a net loss attributable to Century stockholders of $43.1 million for the full year 2023, a $29.0 million decline from the full year 2022, driven primarily by the change in net income (loss) provided by forward and derivative contracts, partially offset by recognition of the full year Inflation Reduction Act Advanced Manufacturing credit and the non-recurring of prior year one time impairment charge. Full year 2023 results were negatively impacted by $73.8 million of exceptional items, in particular $68.3 million of net losses on forward derivative contracts (net of tax), $16.7 million related to the power equipment failure at Jamalco, $9.0 million in curtailment costs related to the Hawesville plant and $6.6 million increase in share-based compensation costs driven by market inputs, partially offset by $26.2 million lower of cost or net realizable value adjustment (net of tax). Thus, Century reported an adjusted net income of $30.7 million, a $5.1 million improvement from the full year 2022.

Adjusted EBITDA attributable to Century stockholders for the full year 2023 was $120.0 million, a decrease of $23.8 million compared to the prior year, primarily driven lower shipment volume and lower realized aluminum prices.

"Century’s businesses performed well despite dynamic conditions in 2023, posting $120 million of Adjusted EBITDA for the year and advancing several strategic priorities, including our acquisition of a controlling interest in the Jamalco alumina refinery,” said Century President and CEO Jesse Gary.

“As we enter 2024, we remain focused first and foremost on the safety of our employees and improving the communities in which we operate,” continued Mr. Gary. “We are also very encouraged by the recently announced Inflation Reduction Act Advanced Manufacturing Credits and the opportunities that this program will create for our US operations. We remain focused on executing our long-term capital programs, including completion of our Grundartangi casthouse project, and continue to operate the business in a disciplined manner during this volatile market environment."

First Quarter 2024 Outlook

The company expects first quarter Adjusted EBITDA to range between $5 to $15 million based on improved raw material costs offset by lower value added product premiums.

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.
