Our M&A services

Our seasoned M&A team serves both domestic and international corporations, investors and sponsors. We provide legal advice in both domestic and cross border transactions mainly in the fields of:

  • private & public M&A
  • private equity
  • venture capital
  • real estate
  • joint ventures

The way we work is based on our project leaders’ and team’s dedication to the project and its objectives, active solution-oriented contribution and up-to-date communication with the client.

Thanks to our long experience in managing and executing sell-side and buy-side M&A processes in an international framework, we have accumulated a strong understanding on how to complete deals successfully. We have a particularly strong track record in industrial investments, divestments, and carve outs in the energy, engineering, manufacturing, and industrial services sectors.

Our M&A team’s service pledge is: “One step ahead – for the good of the client.”

“As with any people business, it’s the people that make the business – and that’s most definitely the case at Procope & Hornborg. Warm, engaged, energetic, informed, driven, solution focused are all words which could describe our experience with the firm, but none of that is at the cost of a strong, supportive culture, which is very important. It is always a pleasure to work with the Procope team, knowing that we are in safe hands.”
