KAP AG Appoints Ralph Rumberg as Chief Transformation Officer to Accelerate Corporate Restructuring
German industrial holding company KAP AG has appointed transformation expert Ralph Rumberg to its management board to drive operational improvements and develop a sustainable profitability strategy amid dynamic market changes.

The Supervisory Board of KAP AG has appointed Ralph Rumberg to the Company's Management Board as Chief Transformation Officer for a twelve-month term. This strategic move aims to strengthen the Group's competitiveness in a dynamically changing market environment and increase the speed of implementation of the transformation process.
Rumberg's primary responsibility will be accelerating the improvement of operating performance across KAP's portfolio companies and developing a future concept that delivers sustained profitability. His appointment expands the Management Board to four members, working alongside Marten Julius, Thorsten Diel, and Stefan Deller, though the temporary appointments of Diel and Deller will conclude as scheduled on October 9, 2025.
Christian Schmitz, Chairman of KAP AG's Supervisory Board, emphasized Rumberg's qualifications, stating the company is gaining a recognized leader with proven expertise in developing and implementing sustainable transformation and strategy programs for industrial holding companies. The appointment reflects KAP's commitment to addressing market challenges through specialized leadership.
Marten Julius, Spokesman of the Management Board, noted that the company has already made progress in recent months with portfolio optimization, including streamlining processes, adapting structures, and capturing synergies. Rumberg's expertise in industrial transformations is expected to provide additional momentum to accelerate these ongoing efforts.
Rumberg brings extensive industrial sector experience, having held previous positions at BMW Motorsport, AMG Mercedes-Benz, Bosch Rexroth, and KOKI Technik. Most recently, he served six years as CEO of GESCO SE, where he successfully restructured the investment portfolio, reduced automotive sector dependence, and implemented comprehensive strategy programs.
The appointment comes as KAP AG, a listed industrial holding company focusing on upper mid-size operating companies, seeks to enhance its competitive position across its three core segments: flexible films, engineered products, and surface technologies. The company operates 19 locations across ten countries with approximately 1,600 employees.
Rumberg expressed enthusiasm for his new role, acknowledging the trust placed in him by the Supervisory Board and committing to work with the team to optimally develop KAP AG drawing on his transformation experience. The temporary nature of his twelve-month appointment suggests a focused, intensive effort to drive immediate improvements in the company's operational performance and strategic direction.
