Planted Area by Crop (hectares) Following the conclusion of grain planting, the total planted area decreased by 2 % compared to the initial estimate . This variation primarily reflects a reduction in soybean and second - crop bean acreage, resulting from strategic and budgetary adjustments . Production per product (tons) Following the review of the crop mix and adjustments to planted areas, the outlook for the 2025 / 26 crop year remains positive, despite irregular rainfall at the start of the cycle, which later stabilized and has supported strong production levels .

‘2 The sugarcane harvest was completed in November, with 1 . 7 million metric tons of sugarcane, corresponding to 67 . 55 tons of cane per hectare (TCH) . For the 2026 sugarcane crop, we estimate production of 2 . 1 million metric tons, with TCH of 79 . 51 , reflecting the renewal of the fields and the normalization of production conditions . Performance fell short of expectations, primarily due to the advanced age of the sugarcane fields, which amplified the impact of high temperatures during crop formation and water deficits during crop development . Additionally, frost events in Brotas (SP), pest outbreaks in Mato Grosso, and a fire in September that affected part of São José Farm further contributed to the decline in productivity during the period . Cattle raising We projected 11,637 head of cattle, distributed across 8,649 hectares of active pastureland in Brazil and Paraguay. Production cost (R$/ha) It is worth noting that the estimates are hypothetical data and do not constitute a promise of performance .
