Variable consideration to Codelco

During the year ended December 31, 2025, we recorded $142 million of income (2024 – $44 million of expense) related to changes in the carrying value of the financial liability for the preferential dividend stream from QBSA to Codelco. The financial liability was previously owed to Empresa Nacional de Minería (ENAMI) but is now owed to Codelco, subsequent to Codelco’s acquisition of ENAMI’s interest in QBSA during 2024. As at December 31, 2025, the carrying value of this financial liability, which is measured at amortized cost, is $402 million (2024 – $548 million) (Note 26). This financial liability is significantly affected by copper prices, the interest rate on the subordinated loans provided by us and SMM/SC to QBSA, operating cost estimates and capital expenditure estimates, which all affect the timing of when QBSA repays the loans. The fair value of the financial liability is approximated by its carrying value, and is considered a Level 3 fair value measurement with significant unobservable inputs in the fair value hierarchy (Note 33).
