Santiago, Chile, April 10, 2024 –Sociedad Química y Minera de Chile S.A. (“SQM”, the “Company”) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) informs that its shareholder, Inversiones TLC SpA, an owner of more than 10% of the SQM’s outstanding shares with voting rights, requested to summon a new extraordinary shareholder meeting to discuss and vote on the transaction contemplated in the Memorandum of Understanding signed by SQM and the National Copper Corporation (“Codelco”) dated December 27, 2023, and modified on March 20, 2024 (the “Memorandum”).

The Company’s Board of Directors agreed to summon an extraordinary shareholder meeting for 10:00 a.m. (Chile time) on Wednesday, April 24, 2024 (the “Meeting”), to discuss the transaction contemplated in the Memorandum, in particular:

1.Management report on the status of negotiations between SQM and Codelco, particularly, whether the parties have reached agreement on the terms and conditions of the contracts that are being negotiated pursuant to the conditions set in the Memorandum, including those that were mentioned at the extraordinary shareholder meeting held on March 21, 2024.

2.Management presentation on the merits, opportunities, advantages, disadvantages and risks that the partnership with Codelco could form for SQM, as well as questions and comments from the shareholders. The viewpoints expressed by shareholders shall not possess binding authority upon the management of the Company, nor shall they discharge management from its responsibilities.

3.Discussion on the legal structure under which the partnership with Codelco would be executed, according to the status of the negotiations on the date of the Meeting, and the steps and legal requirements for its approval in accordance with the regulations of the Chilean Corporations Law and the by-laws of SQM.

Without prejudice to the request of the shareholder Inversiones TLC SpA to summon a shareholder meeting to discuss the matters indicated in letters (a), (b) and (c) above, the Company’s Board of Directors agreed not to submit to shareholders the voting of the approval of the partnership with Codelco, given that: (1) up to the current date, there is neither a partnership agreement nor a final legal structure on the transaction with Codelco to be approved; and (2) should the partnership with Codelco ultimately conforms to the terms previously consulted upon with the Chilean Financial Market Commission (Comisión para el Mercado Financiero), it would be appropriate to approve such transaction by the Company’s Board of Directors and not by the shareholders, as dictated by the Chilean Financial Market Commission in the Official Letter N°27,980 dated February 29, 2024.
