### Notes to the Consolidated Interim Financial Statements

#### March 31, 2025
The Chilean IRS has not issued a settlement for differences on specific mining tax with respect to the 2024 tax year (2023 business year). If the Chilean IRS uses criteria similar to that used in previous years, then it may issue settlements in the future covering this year. The Company's estimate for the amount that could be settled by the SII, corresponding to the business year 2023 and as of March 2025 amounts to MMUS$184.2 (net of first category tax), excluding interest and penalties.

On December 19, 2024, the SII issued settlements Nos. 79-97 which re-determined the mandatory monthly provisional payments for the specific tax on mining activity related to SQM Salar's lithium exploitation for the periods from January to September 2024. The total amount was MMUS$78.3, including a penalty and interest of MMUS$25.3. SQM Salar challenged these settlements through a voluntary administrative reconsideration, which is pending resolution. As of the reporting date, the amount related to interest and penalties totaled MMUS$26.6.
