Century Aluminum restates 2023-2025 financials; changes Jamalco consolidation method
--------------------------------------------------------------------------------

- Audit Committee determines prior financials (FY23-24, interim periods 2024-2025) should no longer be relied upon due to Jamalco accounting change.
- Company will fully consolidate Jamalco JV (55%) instead of proportionate consolidation; no impact on Century net income.
- Restatement boosts total assets ~$180M and equity ~$143M (FY24); gross profit down ~$13M (FY24) and ~$4M (FY23).
- Company expects material weakness in internal controls over financial reporting due to restatement.
- Change follows SEC staff comment letters; audit committee reversed earlier immateriality conclusion on March 2, 2026.
