The supervisory board chairs of German publicly traded companies possess deep knowledge of their companies and industries. At the same time, Egon Zehnder’s 2026 DAX Chair Analysis shows that many chairs follow similar career paths and share similar qualifications and demographic profiles. Germany’s supervisory board chairs bring deep industry and corporate experience to the table—but homogeneity, long tenures, and proximity to day-to-day operations raise governance questions and lack fresh perspectives. Oversight requires more than just experience.
The chairs of DAX supervisory boards have a wealth of experience but often share similar biographical characteristics: 91 percent are men, 82 percent are German, and the average age is 65. Egon Zehnder’s 2026 DAX Chair Analysis thus makes it clear that, on the one hand, these boards benefit from a high degree of continuity and industry knowledge. On the other hand, greater diversity, international perspectives, and broader board experience could further strengthen the supervisory boards’ future viability.
In August, the executive search specialists at Egon Zehnder examined the career paths of 160 board chair appointments at companies listed on the DAX 40, MDAX, and SDAX. The study focused on the question of what experience today’s DAX board chairs bring to the table and how well this experience prepares them for the role of supervisory board chair.
The result: DAX chairs often know their companies and the industry inside and out. 63 percent of the supervisory board chairs examined already had a connection to the company before assuming the role: Most served as regular members of the supervisory board, while a minority held an operational leadership role. Very few are familiar with the company they now oversee from a management perspective.
Eighteen percent of the chairs had already held an operational role in the same company before assuming the chairmanship. Six percent also had a connection through a previous supervisory board appointment. Particularly when transitioning from management to the supervisory board, the question of sufficient institutional distance arises: Of the chairs who previously held an operational role in the company, only 34 percent observed the so-called “cooling-off” period. 66 percent assumed their supervisory board seat before the recommended two-year waiting period had expired. Fifty-five percent of board chairs bring relevant industry experience to the table. This is particularly true for the SDAX. No wonder: A majority never changed industries even once during their careers as executives, and 26 percent even spent their entire careers at the same company.
This proximity to day-to-day operations can be an enormous advantage. After all, it means there is a wealth of practical knowledge available, especially when you consider that DAX board chairs are, on average, 65 years old. However, with regard to effective governance and the separation of powers between the Executive Board and the Supervisory Board, such proximity also carries risks.
There is another indicator that points to challenges in the area of governance: Supervisory Board chairs who were previously members of the board have served an average of 11.9 years. This is very close to the 12-year maximum recommended by the German Corporate Governance Code, which is intended to ensure the board’s independence.
Business administration graduates make up the clear majority of DAX chairpersons. 89 percent have general management experience; specialized roles such as sales (29 percent), finance (28 percent), or strategy (27 percent) appear less frequently on their résumés.
As many as 53 percent of DAX supervisory board chairs had previously served as CEOs. However, this management experience is often very national in scope. 43 percent of the chairs have spent their entire executive careers exclusively in Germany; as expected, the supervisory board chairs in the DAX 40 are the most internationally experienced.
Diversity at the top of DAX boards leaves room for improvement: Only 9 percent of DAX supervisory board chairs are women (though the figure is 13 percent in the DAX 40); 82 percent of supervisory board chairs are German, and 13 percent are from Europe. The analysis found that non-Germans tend to have more well-rounded profiles. Such chairs tend to have worked in more industries and at more companies than their German counterparts, and they are more likely to have earned an MBA.
An analysis conducted by Egon Zehnder of 160 résumés of supervisory board chairs in the DAX shows that the demographic profile of these chairs is homogeneous. The majority are male executives with a background in business administration and limited international experience who are in the later stages of their careers. In short: They know their companies and the industry well. Their experience can provide stability. However, a lack of diversity becomes a problem when it narrows debates within the board to just a few like-minded perspectives. Given the challenges facing the German economy, this could pose a risk.
