| SQM S.A. 2Q2025 Earnings release |     | 2 |

In Australia, sales volumes were lower than in the first quarter, as planned. We anticipate significantly higher volumes in the second half of the year and are therefore updating our full-year 2025 sales guidance for our International Lithium Division to approximately 20,000 of LCE. The Kwinana refinery has completed construction, and achieved first product in commercial specifications in July. We expect an 18-month ramp-up period to reach nameplate capacity of 50,000 tons of lithium hydroxide (25,000 tons attributable to SQM) by the end of 2026. Gross profit (2) for the Lithium and Derivatives segment accounted for 32.4% of SQM’s consolidated gross profit for the six months ended June 30, 2025. Adjusted gross margin (3) for the Lithium and Derivatives segment for the second quarter 2025 was 21%. Specialty Plant Nutrition (SPN) Revenues from our Specialty Plant Nutrition business line for the six months ended June 30, 2025 totaled US$472.6 million, a slight increase when compared to US$468.2 million reported for the six months ended June 30, 2024. Revenues from our Specialty Plant Nutrition business line for the second quarter of 2025 totaled US$260.3 million, almost flat when compared to US$260.5 million reported for the second quarter of 2024.
