the Shareholders’ Meeting.
All the timings mentioned herein shall be read as Brasilia

Exceptionally, to facilitate the participation in the

As provided for in the regulations in effect, those
who do not register under the terms of this Manual until April 28, 2026, at 11:59 p.m., will not be able to participate in the
Shareholders’ Meetings.
After sending the documents requested for participation
in the Shareholders’ Meetings, the Company will analyze the Registration, and the shareholders (or their representatives, as the
case may be) will receive, through the email used for the Registration, a message informing about the approval of their registration to
participate in the AGOE or the reason for their rejection.
The shareholders (or their representatives, as the case
may be) whose Registration has been rejected will be allowed to settle the pending issue identified until 10:00 a.m., on April 30, 2026.
Once the Company validates their capacity and document
conformity after Registration, each shareholder (or their representative, as the case may be) will be accredited to participate in the
AGOE.
| | |
| 5 |  |
On the day of the Shareholders’ Meetings, each
shareholder (or their representative, as the case may be) accredited by the Company shall participate in the AGOE by accessing the Digital
Platform, selecting “Meeting” (“Assembleia”) and clicking on the button “Access Meeting” (Acessar
Assembleia), which will be available for access from 1:00 p.m. on April 30, 2026.
It will not be possible for any person to join the
Shareholders’ Meetings through the Digital Platform, regardless of previous Registration, from 2:00 p.m. on April 30, 2026.
The Company recommends that qualified shareholders (or
their representatives, as the case may be) familiarize themselves with the Digital Platform in advance, including upon consultation of
the platform access guide available, and verify the compatibility of their equipment with the use of the Digital Platform. The participant
shall access the Digital Platform using the browsers Google Chrome or Microsoft Edge to ensure a better experience.
It is also recommended that the shareholders or their
representatives (as applicable) join the AGOE at least 30 minutes in advance of the schedule start time, with the purpose of ensuring
the registration of their access and their participation in the Shareholders’ Meetings.
The shareholders who participate in the AGOE through
the Digital Platform will be considered present and signatory of the respective minutes, pursuant to article 47, § 1, of CVM Resolution
81/22. The Company reiterates that only the shareholders (or their representatives, as the case may be) who register in advance and access
the Digital Platform on the date of the Shareholders’ Meetings, in the manner and period set forth in this Manual, will be considered
present.
Additionally, the Company recommends that, during the
AGOE, participants use headphones, keep their microphones muted and their cameras turned off, except when speaking, in order to avoid
instability in the connection and improve audio quality, it being hereby permitted to the members of the presiding board of the Shareholders’
Meetings to turn off cameras and microphones, when the floor is not open to the participants.
Notwithstanding the foregoing, the Digital Platform
will provide a written and instant dialogue box for communication with the presiding board and among the participants. Shareholders, or
their representatives, who wish to take the floor to make a statement on any matter not related to the Shareholders’ Meetings agenda
must use the usual channels of contact with the Company, through the Investor Relations Department.
The Company emphasizes that it will be the sole responsibility
of the shareholders, or their representatives, to ensure the compatibility of their equipment with the use of the Digital Platform. Under
the terms of the applicable regulations, the Company will not be responsible for any operational or connection problem that the shareholders,
or their representatives, may face that makes it difficult or impossible for them to participate in the AGOE that is not under the control
of the Company, such as Internet connection instability or incompatibilities with the qualified shareholders’ equipment (or their
representative’s equipment).

The Digital Platform provided by the Company complies

simultaneous access to documents presented during the AGOE that were not previously made available; (b) the full recording of the Shareholders’
Meetings; and (c) the possibility of communication among the shareholders.

during the Shareholders’ Meetings; register the attendance and vote cast; comply with a legal order from competent authorities;

| | |
| 8 |  |
If any shareholder wishes to include proposals for candidates

by mail to Rua Dr. Renato Paes de Barros, 1017, 4th floor, ZIP Code 04530-001, São Paulo/SP, to the attention of the
Investor Relations Department (Departamento de Relações com Investidores), along with the documents concerning the

shareholder, within the terms and in the manner established in the applicable regulation.
Participation in the Shareholders’ Meeting
by shareholders who have submitted a Bulletin for Distance Vote:
After submitting the Bulletin for Distance Vote, if
the shareholder also wishes to participate in the shareholders’ meeting virtually, the shareholder must change the “Participation”
(“Participação”) field from “via Bulletin for Distance Vote” (“via Boletim de Voto
à Distância”) to “Live” (“Ao Vivo” ).
In this case, the previously submitted Bulletin for
Distance Vote shall remain valid, and the shareholder may enter and participate in the shareholders’ meeting normally. In order
for the submitted Bulletin for Distance Vote to be disregarded, the shareholder must request its disregard during the shareholders’
meeting. It is emphasized that the change of the “Participation” field to “Live” may only be made up to the final
registration deadline for participation in the shareholders’ meeting, as mentioned above.
| 2.3. | MECHANISMS FOR CONFLICT OF INTERESTS MANAGEMENT |
According to the practice recommended in the Brazilian
Code of Corporate Governance (Código Brasileiro de Governança Corporativa), the Company has mechanisms for managing
conflicts of interests in the voting submitted to the Shareholders’ Meetings.
Article 115, §1 of Law No. 6,404/76 provides that
the shareholder may not vote on the resolutions at the shareholders’ meeting that relate to the appraisal report of assets to which
the shareholder may contribute on the formation of the capital stock and to the approval of its accounts as manager, nor in any other
resolutions that might benefit the shareholder in a particular way, or in which the shareholder has a conflicting interest with the Company’s
interest.
During the AGOE, in case of allegation, by any of the
shareholders present at the meeting, of an alleged conflict of interest of another shareholder that impedes him of voting at the meeting,
or, even, in case of occurrence of another legal hypothesis of voting impediment (including, as the case may be, of participation in a
separate voting for the election of a member of the Fiscal Council), and if the shareholder himself has not declared an impediment, the
chairman or secretary of the meeting shall postpone the resolution in order to listen and receive such allegation (which shall include
the name of the shareholder in potential conflict, the matter to be resolved and the alleged existent conflict),
with the possible manifestation in contrary from the relevant shareholder, before putting the matter to a vote. The chairman of the meeting
himself may, in identifying a potential voting impediment, request clarifications on the situation from the shareholder, before putting
the matter to a vote. If an impediment is confirmed, the relevant shareholder must be immediately absent from the discussions on the matter
and abstain from voting.
| | |
| 9 |  |
If a conflict situation is identified by a shareholder
and such situation is not informed as set forth above, such shareholder must inform the Company of the situation within fifteen days as
of the date of the AGOE, so that the Management of the Company can take the appropriate measures with regard to the resolution.
Aligned with the understandings of CVM, in situations
in which the voting impediment is clear and the shareholder does not abstain from voting, the chairman of the meeting has the power to
declare such impediment, not being allowed to impede the voting in other situations, notwithstanding the legal provisions on the potential
nullity of the casted vote.
