Planted Area by Crop (hectares) Due to weather conditions, we concluded the 24 / 25 crop year with a 3 % reduction in total planted area compared to the initial estimate, which mainly affected soybean, cotton, and bean crops . Part of the area was shifted to corn, taking advantage of the more attractive price environment for this crop . For the 25 / 26 crop year, we estimate maintaining the planted area at 172 , 610 hectares, in line with the 24 / 25 crop . Even with the sale of farms, we will keep the total planted area unchanged thanks to the incorporation of a new lease in Mato Grosso and the entry into production of recently converted areas . Production per product (tons) The production of grains and cotton was 9% below the initial estimate, as a result of three main factors: (i) reduction in the planted area; (ii) adverse weather events that impacted the production cycle; and (iii) operational challenges during crop development.

Sugar cane 2024 Harvest 2025 Harvest Change 2025 Harvest Change Sugarcane Harvest Year Result In April, we started harvesting the new sugarcane crop . Until June 30 , 2025 , 585 . 4 thousand tons were harvested, with TCH of 75 . 06 . The performance of the crop was below the expected due to a set of factors : high average age of the sugarcane field, above - average temperatures in crop formation, water deficit during the period of greater plant development and occurrence of frost in Brotas/SP . In addition, we had an incidence of disease in Mato Grosso . Given this scenario, we updated our estimates and projected a production of 1 . 9 million tons, with TCH of 71 . 53 . Cattle raising With the sale of Fazenda Preferência in June 2025, we updated our cattle raising estimates by adjusting both area and herd. Production cost (R$/ha) It is worth noting that the estimates are hypothetical data and do not constitute a promise of performance .
