(2)In June 2025, the Company and Spinnova Plc entered into a non-binding term sheet with the objective of terminating the corporate partnership in the joint venture Woodspin Oy. This will result in the Company disposing of its entire interest in both Woodspin Oy and Suzano Finland Oy to Spinnova Plc, for the amount of one euro each. As a result of this transaction, which is still subject to definitive formalization, the following accounting effects were recognized: (i) R$(117,848) related to the impairment of the investment and R$(15,636) related to the realization of other comprehensive income from the joint venture Woodspin Oy and (ii) R$(63,634) related to the write-off of goodwill from the associate Spinnova Plc. These impacts were recognized in the income (loss) from associates and joint ventures line item
(3)In August 2025, as part of the ongoing process of divesting its investment in Spinnova Plc, the Company entered into a Share Purchase Agreement (“SPA”) and recognized an accounting effect in the amount of R$(28,679), related to the obligation to make an additional capital contribution, as stipulated in the closing conditions of the transaction..
