Form 10-K for the Fiscal Year Ended December 31, 2024 Notes to the Consolidated Financial Statements Note 2. Acquisition of Jamalco, page 64

1. We note your responses to prior comments 1-3. We believe the Production Assets should be accounted for as part of the Jamalco JV. Considering your total assets would increase by approximately 9% and total equity would increase by approximately 20% as a result of accounting for the Production Assets as part of the Jamalco JV, we believe that the error is material. Please restate your financial statements accordingly. January 14, 2026 Page 2
