SBS: 6-K · acquisition merger
SABESP and EMAE confirmed that the withdrawal-right period for EMAE's share merger expired on October 19, 2026, with zero dissenting shareholder requests, meaning no reimbursement payments are owed.
The timetable is confirmed: EMAE shares stop trading on B3 on October 23, and on October 27, EMAE shareholders will receive 1.3195 SABESP common shares per EMAE share.
The clean withdrawal process removes a procedural risk to the merger's consummation, consolidating EMAE's water and energy assets under SABESP, with fractional shares to be auctioned on B3 after November 4.

SBS: 6-K · amendment
SABESP furnished its corporate bylaws via Form 6-K on September 22, 2026, signed by CFO and Investor Relations Officer Daniel Szlak. The document is a governance disclosure with no financial results, transactions, or operational changes.
Key governance terms include a share capital of R$ 21.5 billion divided into 3,534,409,282 common shares plus one special non-voting preferred share held exclusively by the State of Sao Paulo, which carries veto rights over the company's name, purpose, and voting limits. Any shareholder or shareholder group is capped at 30% of votes, and the special preferred share is extinguished if the State's common shareholding falls below 10%.
The bylaws also codify a mandatory 25% minimum dividend payout of net profit, a nine-member board with at least three independent directors, and a requirement that any shareholder crossing 30% of capital launch a mandatory tender offer at no less than 200% of specified reference prices. None of these provisions constitute new developments; the filing is routine.
