Executive summary

• Net revenue reached R$4.95 billion in 1Q26, up 2% year-over-year, driven by a 12% increase in sales volume across all business segments despite macroeconomic volatility and a stronger Brazilian real impacting export revenues.

• Adjusted EBITDA was R$1.67 billion, down 10% year-over-year, reflecting the impact of scheduled maintenance stoppages and currency appreciation, partially offset by higher sales volumes.

• Net loss of R$497 million in 1Q26, compared to net income of R$446 million in 1Q25, mainly due to lower EBITDA, negative fair value variation of biological assets, and higher financial expenses.
