Shareholders must instruct their custodian bank to register them as shareholders in the share register with voting rights by sending an application for registration to DDM Holding AG, c/o SIX SAG AG, Share Register, Baslerstrasse 90, CH-4601 Olten, Switzerland.

Please note that the registration process may take time and must be completed by the Record Date. To ensure their registration in time for the AGM, shareholders are therefore kindly invited to issue instructions to their custodian bank as soon as possible.
