Suzano reiterates that it is committed to its responsibility to continue supplying Brazil and the world with cellulose, paper, and sanitary papers, essential raw materials or critical items for the hospital, pharmaceutical, food, and personal hygiene network, among others because it believes that it's only good for the Company if it's good for the world.

Note that documents in English and Spanish are exempt from free translation.

Further guidance on how to Register for Attendance can be found in the Digital Platform Manual, available at https://help.atlasagm.com/hc/pt-br.

Once the representation documents sent in accordance with the above terms are in order, the Company will authorize the Shareholder’s Attendance Registration. The shareholders who requested to participate by videoconference though the Digital Platform will be able to access the Annual General Meeting (AGM) in the 'Overview' tab of the Digital Platform on the date of the meeting.

In the event of the need for supplementary documentation and/or additional clarifications with respect to the documents sent for the purposes of the Attendance Registration, the shareholder will receive the request to supplement the Attendance Registration on the Digital Platform via the e-mail address informed in the Attendance Registration.

According to article 6, third paragraph, of RCVM 81/22, the Company clarifies that, if the shareholder do not make the Attendance registration, under the terms established above, by and including April 23, 2025, or if the requests for additional documentation and/or additional clarifications referred to in the previous paragraph are not met to attest to the regularity of the shareholder's representation, it will not be possible for the shareholder to attend in the AGM through the Digital platform.

The Company also highlights that the Digital Platform Attendance Registration is unique and non-transferable, with the shareholder (or their respective proxy or representative, as applicable) assuming full responsibility for the possession and confidentiality of the information and guidelines transmitted to them by the Company under this Manual.

The Company also requests that, on the day of the AGM, qualified shareholders access the Digital Platform at least 30 minutes before the scheduled meeting time, to allow the validation of access and attendance of all shareholders. Access to the AGM will not be permitted after meeting has begun.

To access the Digital Platform, you need a device with a camera and audio that can be enabled. If there is any access difficulty to the Digital Platform, the shareholder must contact via Chat of the Platform.

Finally, the Company clarifies that it is not and will not be liable for any operational or connection problems of the shareholder, as well as for any other problems external to the Company that may make it difficult or impossible for the shareholder to attend the AGM through the Digital Platform.

As provided in articles 30 et seq. of RCVM 81/22, the Company's shareholders may also vote at the AGM through distance voting, to be formalized through the Distance Voting Ballot (“Ballot”), available on the Company’s website (www.suzano.com.br/ri), in the Documents delivered to the CVM - 2025 Meeting area, and also on the CVM websites (www.cvm.gov.br) and B3 (http://www.b3.com.br).

(i) through the transmission of instructions for completing the Ballot to the respective custodian of each shareholder, in accordance with the procedures established by them and the documents and information required by them;

(ii) by transmitting the instructions for completing the Ballot to the central depositary, directly through the electronic system made available by B3, through the Investor Area (available at https://www.investidor.b3.com.br/), in the “Services” section, under “Open Meetings”;

(iii) through the transmission of instructions for completing the Ballot to the financial institution contracted by the Company to provide securities recordkeeping services, in the case of shares that are not deposited in a central depository, in accordance with the procedures established and the documents and information required by it; or

(iv) directly to the Company, by completing and signing the Ballot on the Digital Platform (via link https://atlasagm.com), pursuant to article 28 of RCVM 81/22, after completing the Attendance Registration and presenting the other representation documents and proof of ownership indicated in item (1) above.

Additional instructions for filling in and digitally signing the Ballot through the Platform can be found in the “Guide for voters”, available in the “Help” section of the Digital Platform website (via link https://atlasagm.com).

Voting instructions must be received by the custodian agent, the bookkeeper, the central depositary or the Company no later than four (4) days before the date of the AGM, i.e., up to and including April 21, 2025.

After the term for distance voting, that is, April 21, 2025 (inclusive), shareholders will no longer be able to change the voting instructions sent, except in the AGM itself, via attendance through the Digital Platform, when they may specifically request the disregard of voting instructions sent by Ballot before the respective matter is submitted to a vote.

The Company's Management strongly encourages shareholders to make special use of this method of voting, even giving preference to the options referred to in items (i) and (ii) above (i.e., transmission of the BVD to the custodian agent, central depositary or bookkeeper). If the option adopted is to send the BVD directly to the Company, the Management reinforces the need to Registration Attendance in order to send the BVD through the Digital Platform.
