[6-K] CHEMICAL & MINING CO OF CHILE INC Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Sociedad Química y Minera de Chile S.A. (SQM) is providing unaudited consolidated interim financial statements for the nine months ended September 30, 2025 as an exhibit to this report. These interim figures are prepared on the same basis as the audited consolidated financial statements included in the company’s Annual Report on Form 20-F for the year ended December 31, 2024.

The interim statements differ from the Spanish-language interim financial statements filed in Chile mainly in how income tax expense related to the specific tax on mining activity in Chile is recognized. In Chile, this tax expense had been applied to 2024 interim periods, while in the Form 20-F financial statements it had been recognized in the 2023 fiscal year.
