Staff comment: We have considered your response to prior comment 1.

Accordingly, we continue to believe that your previously issued consolidated financial statements are materially misstated and, therefore, should be restated. letter →

Company response: to Comment 1 Requested by Century Aluminum Company Pursuant to 17 C.F.R. 200.83 [CENX – 2] February 17, 2026 Also identified were disclosure only misstatements within our inventories and variable interest entity footnotes in our 2024 Form 10-K. The Company has concluded that these errors, individually and when aggregated with the impact from consolidation of the Production Assets are not material to the periods presented, and do not cause the financial statements taken as a whole to be materially misstated.
