Insights
Braskem plans a digital EGM to overhaul bylaws and governance.
Braskem S.A. is convening an Extraordinary General Meeting on May 28, 2026 to comprehensively revise its bylaws. The changes are linked to a new shareholders’ agreement and focus on clarifying articles, realigning governance rules, and incorporating key board committees into the bylaws.
The agenda also proposes synchronizing the Executive Board’s term with the Board of Directors’ two-year mandate starting from the April 29, 2026 AGM election, plus electing directors and replacing Fiscal Council members. These steps formalize governance arrangements following previously disclosed shareholding transactions.
The meeting will be held exclusively via Webex, with participation through remote voting ballots or the digital platform. A 5% minimum shareholding is required to request multiple voting for board elections. Actual impact will depend on how shareholders vote on the proposed bylaw reforms and board slate.

GUIDE TO USING THE WEBEX PLATFORM FOR ACCESS AND PARTICIPATION
The Company clarifies that the Digital Webex Platform was chosen to carry out the Shareholders Meeting because it fulfills the requirements provided for in art. 28 Paragraph 1 of CVM Resolution 81, as it allows Shareholders the opportunity to express themselves and have simultaneous access to documents that have not been previously presented and that are presented during the Meeting. In addition, the Digital Platform allows full recording of the Meeting, as well as communication between participants, through the option “Chat” on the platform (see how to use this function in item 2.3 below).
Therefore, the Company makes the instructions below available to its Shareholders to serve as a guide / manual for using the Digital Platform on the day of the Meeting, in order to facilitate the participation of all those involved in the event.
Introductory Information

The access to the Meeting via the Digital Platform will be restricted to shareholders or their representatives / attorneys-in-fact (“Participants”), members of the Company, and other persons whose presence is mandatory under the law or applicable regulation. The links to access the Digital Platform, containing the individual invitations, will be sent to the e-mail addresses that made the access request. Only one individual invitation will be sent per Participant.
The Company hereby informs that it will not authorize the participation in the Meeting of any Participant who has not requested the access link within the period indicated above, as well as for the Participants who request the link, but did so without presenting the necessary participation documents within the period above.
Participants who are accredited within the period indicated above undertake, as of now, to: (i) make use of individual invitations only and only for participation in the Meeting; (ii) not to transfer or disclose, in whole or in part, the individual invitations to a third party, whether a shareholder or not, the invitation being very personal and non-transferable; and (iii) do not record or reproduce, in whole or in part, nor transfer, to a third party, whether he is a shareholder or not, the content or any information obtained on the Digital Platform during the Meeting.

The manifestation will be exercised when the organizer of the event releases the audio of the requesting Participant. Likewise, the “Chat” function may also be used for communication among the Participants.
Responsibilities and Rights
Braskem will not be responsible for connection problems that the Participants may face and other situations beyond the Company's control, such as instability in the internet connection or incompatibility of the Digital Platform with the Participant's equipment.
