Analysis · SBS · Energy & Transportation
The final approval needed to consolidate the subsidiary came on September 16, 2026, when EMAE shareholders voted to merge their shares into Sabesp. With the exchange ratio of 1.3195 Sabesp shares per EMAE share now locked in, dissenting EMAE shareholders have until October 19, 2026 to exercise withdrawal rights at R$18.18 per share. This removes a long-running overhang and simplifies Sabesp's corporate structure, though the withdrawal period introduces a near-term cash outflow risk if many EMAE shareholders dissent.
