Corporate governance analyst

Digital EGM to vote on board seat and bylaw updates.

Braskem plans an exclusively digital EGM on November 13, 2025. Items include a board replacement tied to appointments by Novonor and NSP Investimentos and multiple bylaw amendments covering corporate purpose wording, board election procedures, and approval thresholds.

Amending article 26 could recalibrate decision thresholds and permit the Board to maintain or adjust them, while removing subsidiary auditor selection from Board responsibilities. These are structural governance changes, not operating results.

The Management Proposal and remote ballot are available via CVM, company, and B3 sites. Shareholders must submit participation documents by November 11, 2025 to access the Webex platform.
