Dr. Christian Frank hands over CEO position to Alaaddin Aydin
Dr. Christian Frank, General Manager at Sikora GmbH, will hand over operational responsibility as CEO to Alaaddin Aydin, also General Manager, effective July 1, 2026.

Going forward, Christian Frank will focus within the General Management on the strategic development of Sikora, overseeing a smooth transition, and pursuing potential acquisitions and growth initiatives (M&A).
Upon assuming the role of CEO, Alaaddin Aydin will take over all business areas previously led by Christian Frank – such as R&D, Operations, and Finance – and will be responsible for their further development.
Holger Lieder, also a member of Sikora’s General Management, will continue to retain responsibility for Sales, Service, Marketing, and Internal Services.
In addition to this new role as CEO, Alaaddin Aydin will continue to serve in his strategic capacity as VP of Maag Germany. This will allow the perspectives of Maag and Sikora to be combined under one roof and synergies to be leveraged strategically to ensure the company’s continued success. Thorsten Thuemen will take over the day-to-day operations of Maag Germany as Managing Director effective July 1, 2026.
Following a successful transition phase, Christian Frank will leave Sikora at the end of 2027 at his own request to take on new entrepreneurial roles and challenges outside the group. With this early reorganization and the planned joint transition period, Sikora is laying the groundwork for sustaining the company’s success in the long term.
