Shareholders' Committee

For the owners of GG, it is of major interest to ensure the essential characteristics of a family-owned company: long-term company policy with short decision-making processes.

For this reason, the Shareholders' Committee (GSA for short) was established with 8 representatives of the shareholders. They are the first point of contact for the management to discuss strategic issues, to make quick decisions and to prepare resolutions for the shareholders' meeting. Niki Griller was elected as chairman and Dominik Jacquelin as deputy.
