#### Other long-term benefits
The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees.

Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as not funded .

Benefit payment conditions

The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system 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”.

#### 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 March 31, 2025, and December 31, 2024, the value of assets associated with the SQM NA pension plan amounts to ThUS$5,266, respectively.
