How To Register Shares

As part of our continued efforts towards good corporate governance we encourage shareholders to exercise their voting rights at the Annual General Meeting (AGM) of Idorsia Ltd.

The registration of shares is not mandatory under Swiss law. Therefore, registered shares are not automatically registered in our Share Register.

Idorsia has mandated areg.ch to administer its Share Register. Investors wishing to register their shares are kindly asked to contact their prime custodian (e.g. your banker or broker) to request a share registration form. After completing the form, your custodian will send it to areg.ch who will then take care of the registration. The custodian will receive a confirmation directly from areg.ch once the registration has taken place.
