CMS advises on the sale of Complementa AG to Zürcher Kantonalbank

Zürcher Kantonalbank acquires Complementa AG. Complementa AG has been supporting Zürcher Kantonalbank (ZKB) with investment reporting services since 2006 and has become an important partner of the bank. ZKB has taken over Complementa as of July 26, 2024. The bank is thus consolidating its important position in the area of custody services. At the same time, the takeover provides Complementa with a viable, long-term succession solution. This step ensures the smooth continuation of the often long-standing client relationships. For Complementa's clients and employees, this solution represents continuity and stability.

Heinz B. Rothacher will relinquish his role as CEO, but will continue to be represented on the Board of Directors. From September 2024, Markus Wirth, currently Head of Custody at ZKB, will become CEO of Complementa. He will continue to manage the company together with the existing management team. 

A team of CMS led by Dr Daniel Jenny (Partner) and Florian Jung (Senior Associate) provided comprehensive legal advice to the seller on the transaction. The team also included David Hürlimann (Partner, Tax), Christian Gersbach (Partner, Employment), Rafael Gruber (Trainee, Corporate/M&A) and Nadine Anwander (Trainee, Corporate/M&A).
