July 1, 2021

Stuttgart/Munich, June 29, 2021 – BANSBACH GmbH, one of Germany’s large medium-sized auditing and tax consulting firms headquartered in Stuttgart, today (Tuesday) acquired the majority shareholding of the Munich-based O&R group.

The merger of the company groups will create an auditing and consulting firm with combined revenues of around EUR 50 million and more than 400 employees. O&R will keep its brand and become a member, and wholly owned subsidiary, of the BANSBACH group. Both firms are also members of Kreston Global, a global network of medium-sized auditing and tax consulting firms.

The merger is the next step in BANSBACH’s strategy to expand its footprint as an integrated consulting firm throughout southern Germany. The BANSBACH group is now expanding its presence into Bavaria for the first time, in addition to Baden-Wuerttemberg, Hesse, Saxony and Thuringia. The merger also strengthens its expertise in these areas and also further expands its teams around the core competencies of auditing and tax consulting.

“We are very pleased that this strategic step will allow us to continue our expansion in southern Germany and strengthen our consulting expertise”, said BANSBACH’s managing partner and president-in-office of the German Chamber of Public Accountants, Gerhard Ziegler.

“This merger represents a strategically important milestone for the continued successful development of the O&R group”, commented Dieter Heidemann, Partner and Chairman of the Board of the O&R group.
