SQM ANNOUNCES FULL COMPLETION OF MERGER WITH CODELCO AFTER FAVOURABLE SUPREME COURT RESOLUTION

Santiago, Chile – January 27, 2025 - Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) announces that the condition precedent related to the merger by absorption (the “Merger”) of Codelco’s subsidiary, Minera Tarar SpA, into the Company’s subsidiary, SQM Salar SpA (now “Nova Andino Litio SpA”), has been resolved, allowing the previously announced transaction to take full effect.

As disclosed on December 27, 2025, the completion of the partnership between the Company and the National Copper Corporation of Chile (“Codelco”) for the mining, production, commercial, community, and environmental development of the Salar de Atacama—through the Merger of Codelco’s subsidiary, Minera Tarar SpA, into the Company’s subsidiary, SQM Salar SpA (now “Nova Andino Litio SpA”)—was subject, among other matters, to a condition subsequent. This condition required that the Supreme Court accept the appeal filed by Inversiones TLC SpA under Case No. 52,750-2025 (“Tianqi’s Appeal”) against the judgment issued by the Court of Appeals of Santiago on November 11, 2025, in Case No. 508-2024 (the “Condition Subsequent”).

On January 26, 2026, notification was given of the Supreme Court’s ruling confirming the judgment of the Court of Appeals of Santiago, thereby rejecting Tianqi’s Appeal in its entirety.

As a result of the foregoing, the Condition Subsequent to which the Merger was subject has failed, thereby confirming its completion for all legal purposes.
