Lenz & Staehelin‘s corporate and M&A practice sets itself apart with its capabilities in both public M&A and private equity transactions. The firm is the first port of call for a number of international private equity funds and strategic buyers. Tino Gaberthüel and Andreas Rötheli jointly oversee the team. Gaberthüel draws on over two decades of experience in both private and public M&A, while Rötheli regularly counsels institutional clients on M&A and real estate deals, also tackling complex LBOs. Simone Ehrsam is active on cross-border mandates, and Matthias Wolf is trusted by listed companies, handling acquisitions and corporate restructurings on their behalf.
