Holders of record of ADSs as of close of business on Monday, April 27, 2026, U.S. Eastern Time (the “ADS Record Date”, together with the Shares Record Date, the “Record Dates”) will be able to instruct the Depositary, as the holder of record of Shares (through a nominee) represented by the ADSs, how to vote the Shares represented by such ADSs. Such voting instructions may be given only in respect of a number of ADSs representing an integral number of Shares.
