Business context and reporting period
Sabesp filed this Form 6-K on October 9, 2026, reporting an October 8 joint update with EMAE to the estimated timetable for Sabesp’s merger of all EMAE shares it does not already hold. EMAE shareholders are to receive Sabesp common shares. This is a transaction update, not a financial-results filing; the filing does not provide a clear financial reporting period beyond identifying the update as being for October 2026.

Outlook, risks, and contingencies
The listed transaction dates are estimates. The filing says additional information will be disclosed as required. Tax-related procedures are specified for non-resident investors (NRIs), including deadlines to provide information concerning tax on capital gains from exercising withdrawal rights or participating in the merger. Fractional-share auctions and related payments are conditional and have no stated dates. The filing includes standard forward-looking-statement language warning that actual events and outcomes may differ from management’s expectations because of risks and changing assumptions.
