#### 1.6 Dividend payable to Codelco
On May 31, 2024, SQM and Codelco signed a Joint Venture Agreement (available at: https://ir.sqm.com/news-events/information-related-to-negotiations-with-codelco ), defining the rights and obligations of the parties involved in forming an association for mining, production, and commercial activities related to the exploration and exploitation of specific CORFO-owned mining properties in the Salar de Atacama (directly or through subsidiaries or representative offices). The formation of the joint venture is subject to the fulfillment or waiver of certain conditions precedent.

As of the publication date of SQM S.A.'s first quarter 2025 financial statements, not all conditions precedent set forth in the Joint Venture Agreement have been fulfilled. This agreement establishes that if the aforementioned conditions precedent are met within the 2025 calendar year, the preferences and economic rights of the series A shares (Codelco) and series B shares (SQM S.A.) of the joint venture will become effective as of January 1, 2025. The economic rights established in the association agreement include the distribution and payment of dividends in accordance with the methodology established therein.

The dividend payable to Codelco is calculated based on its share of annual Adjusted Net Income. As outlined in the Joint Venture Agreement, Codelco's proportion corresponds to 33,500 tons of lithium carbonate equivalent over the total tons of lithium carbonate equivalent sold in the year. The joint venture also outlines how to calculate the adjusted net income. Per IFRS, no provision for this amount has been recorded in SQM S.A.'s financial statements; however, when the Joint Venture Agreement becomes effective, this amount will be deducted from consolidated net income attributable to owners of the parent of SQM S.A. and will be reclassified to income for distributed to non-controlling interests. See note 3.25, 19.5 and 20.8.
