Ronald Sauser will head the M&A group, joined by Fabian Denneborg, Lars Frölich and Marco Hirsiger. Stefan Rösch-Rütsche was Sauser's predecessor. Rösch-Rütsche took over the lead for TAS (transaction advisory services) as a whole in Switzerland, the firm told this publication.

The appointment comes at a time when there continues to be growth potential among M&A areas in Switzerland. In the wealth management arena, there have been a number of cases of Swiss banks buying or selling businesses and this market, among others, is expected to see continued consolidation.

Sauser was formerly chief executive of Leonardo & Co, the investment bank. His appointment is effective from the start of February.
