Cancellation of publicly held syngenta shares

Syngenta has today announced that the Appellate Court Basel-City (Appellationsgericht Basel-Stadt) has cancelled all publicly held registered shares of Syngenta AG.

Following the delisting of the Syngenta shares from the SIX Swiss Exchange, holders of cancelled shares will be paid a cash compensation in the amount of USD 465 for each cancelled share. This amount corresponds to the offer price that had been paid by CNAC Saturn (NL) B.V. in its public tender offer for all publicly held registered shares of Syngenta AG.

SIX Exchange Regulation had already approved the delisting of the Syngenta shares from SIX Swiss Exchange on October 26, 2017, subject to the decision of the Appellate Court.

The official announcement of the delisting and the last trading day will be published by Syngenta as required by applicable rules.
