The close cooperation between the Supervisory Board and the Management Board is part of our success.
The Supervisory Board supports GK's Management Board in its leadership, management and strategy tasks, as well as providing advice. In addition, the Supervisory Board monitors the Management Board to ensure compliance with all applicable laws, as well as our articles of association and rules of procedure. The Supervisory Board is therefore involved in all decisions that are of fundamental importance to GK Software.
The Supervisory Board at GK Software SE is comprised of three members in line with the articles of association. Provided that the annual shareholders’ meeting does not decide differently, the members of the Supervisory Board are elected for a period until the end of the annual shareholders’ meeting, which decides to approve their actions for the fourth business year after the start of their time in office.
