Insights

Sabesp follows Brazilian control-sale rules with a priced tender for EMAE minorities.

Sabesp has requested registration of a mandatory-style tender offer for up to 3,695,800 EMAE common shares after acquiring control. The offer targets remaining minority holders, excluding shares already held by Sabesp or in treasury, and is tied to Brazilian corporate law requirements on control transfers.

The offer price of R$49.46 per share is set at 80% of the R$61.83 per-share value used in the control sale that closed on January 21, 2026. The filing clarifies that both 11,009,550 common and 29,950 preferred EMAE shares were included in the original R$682,643,113.65 transaction amount.

The consideration will be indexed by the SELIC rate from the control-closing date to the tender settlement date, which aligns the economic terms over time. Actual impact on Sabesp and EMAE’s free float will depend on how many of the up to 3,695,800 eligible shares are tendered once the offer period and detailed notice are in place.
