SQM INFORMS REVISED ACCOUNTING TREATMENT FOR LITHIUM MINING TAX

Santiago, Chile. April 29, 2024.- Sociedad Química y Minera de Chile S.A. ("SQM" or the "Company") (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) informs the following information:

In relation to the matter reported in the press release (hecho esencial) dated April 7, 2024, today the Company's Board of Directors has reviewed the accounting treatment of the tax claims the Company has with the Chilean Internal Revenue Service (“Servicio de Impuestos Internos” or “SII”) as a result of the erroneous application by the SII of the specific tax on mining activities for the exploitation of lithium, as disclosed in note 21.3 of the most recent financial statements filed by the Company with the Chilean Financial Market Commission (“Comisión para el Mercado Financiero” or “CMF”).

As a result of this review, the financial statements that the Company has filed on the Form 20-F with the Securities and Exchange Commission in the United States (the “20-F”) include differences with respect to the last financial statements issued in Chile, as set forth below in an accounting reconciliation between the consolidated financial statements of the Company filed with the CMF on February 28, 2024, and the financial statements filed on the 20-F.

This adjustment will also be reflected in the Company's consolidated financial statements for the period ended March 31, 2024.

Furthermore, due to the timing difference between the filing of the latest financial statements (together with the integrated annual report) in Chile and the filing of the 20-F, as well as the market disclosure criteria required by the external auditors, the Company’s Board of Directors has agreed to update the contingencies notes to the consolidated financial statements and the risk factor on the compliance standards and investigations applicable to the Company on the 20-F.
