 as established in Decree Law 3,500 of 1980. Methodology The determination of the defined benefit obligation is made under the requirements of IAS 19 “Employee benefits”. 18.4 Post-employment benefit obligations Our subsidiary SQM NA, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities. For workers under contract, since 2003, SQM NA offers benefits related to pension plans based on the 401-K system to its employees, which does not generate obligations for the Company. As of September 30, 2025, and December 31, 2024, the value of assets associated with the SQM NA pension plan amounts to ThUS$5,266, respectively.
