During the second quarter of 2025, both sales volumes and revenues held steady compared to the same period last year, reflecting resilient demand across our specialty crop markets in South America, Mexico, the United States, and Spain. Prices remained strong, supported by robust potassium chloride pricing and sustained demand for potassium nitrate in key agricultural regions. We expect these market conditions to continue during the second half of the year, thus expecting relatively stable prices and volumes for the rest of the year. Gross profit (2) for SPN segment accounted for 12.7% of SQM’s consolidated gross profit for the six months ended June 30, 2025. Adjusted gross margin (3) for the SPN segment for the second quarter 2025 was 17%.
