Successful transactions create blooming businesses that grow and increase their profitability.

Mergers and acquisitions are essential in order to create a healthy and competitive business environment. The buyer gets access to new technology, expertise or a new industrial or geographic market, while the seller can focus on developing its core business or reallocate its investment. Successful transactions create blooming businesses that grow and increase their profitability.

We have expertise within all areas that may be affected by a transaction. We regularly lead the largest M&A projects in the market, using our own developed project management model and the newest cutting-edge technology to improve processes and deliver exceptional results to the clients.


Thommessen advises both large, medium-sized and small companies across all industries, private equity firms, family offices and investment banks. We are involved in strategic considerations, negotiations, signing and implementation of a wide range of domestic and cross-border mergers and acquisitions.
