#### 30 EVENTS AFTER THE REPORTING PERIOD
30.1 Tariffs on exports to the United States of America

In April 2025, the United States government announced the implementation of an import tariff program with country-specific rates, starting from a minimum rate of 10%. In July 2025, a 50% tariff was announced on products imported from Brazil, effective as of August 2025.

In the context of the Company’s operations, exports of pulp remain exempt from this additional tariff, according to official information released by U.S. trade authorities. However, certain products within the paper portfolio were included under the 50% tariff scope.

Despite the partial inclusion of the paper segment, the Company has limited commercial exposure to the U.S. market. Based on the assessments performed through the date of approval of these financial statements, no material impacts were identified on the Company’s financial performance or cash generation.

#### 30.2 Exchange of biological asset
On August 6, 2025, the Company signed an agreement with Eldorado Brasil Celulose S.A. (“Eldorado”) for the exchange of a biological asset corresponding to 18 million cubic meters of standing timber located in the state of Mato Grosso do Sul.

The transaction involves the exchange of standing timber (biological asset), suitable for the pulp production process. Eldorado will transfer the agreed volume of currently mature standing timber to be harvested by Suzano between the projected years of 2025 and 2027. In return, Suzano will deliver an equivalent volume of currently immature standing timber to be harvested by Eldorado between the projected years of 2028 and 203
