In December 2024, Law 15.079/2024 was published, establishing the Additional Social Contribution on Net Income (CSLL) in the process of adapting Brazilian legislation to the GloBE rules, whose application comes into effect as of January 1, 2025. The main impact is the need to adapt compliance structures and the calculation of any additional CSLL (Top-up Tax).

The Company reaffirms its commitment to tax compliance and is already taking the necessary actions to ensure the proper implementation of the new rule in Brazil, in line with global best practices and current legislation.

The Company also continually assesses legislative developments in the jurisdictions in which it operates in order to map potential effects on its operations.

(1) Refers to the acquisition and merger of 100% of the share capital of the companies Timber VII and Timber XX (note 1.2.6).

The calculation of fair value of the biological assets is determined using unobservable data, therefore it falls under Level 3 in the hierarchy set forth in IFRS 13 - Measurement of Fair Value.

In our model, the assumptions regarding the average annual growth rate (IMA) and average gross selling price of eucalyptus are particularly sensitive. Any increase or decrease in these assumptions could lead to significant gains or losses in the fair value measurement.
