Corporate and Mergers & Acquisitions

Praised by Chambers for its «excellent track record acting on high-profile public takeovers and private equity transactions», Lenz & Staehelin enjoys a leading position in domestic and cross-border private and public M&A transactions, and has been party to many of Switzerland’s most important corporate deals. Around 70 partners and associates form the country’s strongest Corporate and M&A practice group.

In addition to advising on corporate law in general, the group also has ample experience in structuring complex cross-border and domestic M&A transactions and working with private equity investments. We also rank among the key players in the highly sophisticated field of public tender offers.

Besides advising on many of the major transforming deals in Switzerland, we regularly act as counsel on smaller transactions.


Lenz & Staehelin’s Competition law group is one of the largest in Switzerland. It is one of only very few firms in the country with the resources to handle the most complex mandates. Clients come to us for advice on the complete range of antitrust/competition, regulatory and trade issues spanning merger control and joint ventures, restrictive practices, market dominance, cartel investigations and related litigation, market/sectoral investigations, competition litigation, licensing and distribution, intellectual property, liberalization, public procurement and trade/WTO matters.

Lenz & Staehelin regularly advises clients in many different industries, including the media, telecommunications, automobile, FMCG, pharmaceutical, industrial, energy, healthcare, technology and luxury sectors. In addition, we also advise financial institutions on both the antitrust/competition aspects of corporate deals as well as in contentious matters in courts throughout Switzerland. We represent clients in particular before the Swiss Competition Commission, the Swiss Price Supervisory Office and in civil litigation in cantonal and federal courts in Switzerland.
