Year

"Zahn stands for high-quality products in the field of flat roof fastening technology. We are pleased to welcome the Zahn brand into the SFS family and to collaborate with its management. Thank you to the team at Walther Transaction for their professional and pleasant support throughout the due diligence process and negotiations leading up to the closing. We are very satisfied with the collaboration and the successful transaction."

Oliver Küppers

Head of Region Europe NE at SFS

Approach

Walther Transaction supported the SFS Group during the closing phase of the transaction by managing the overall process, coordinating the due diligence, and facilitating the negotiations.

Challenges

Managing an inexperienced seller with a complex family situation. Cultural differences between buyer and seller regarding the size of the companies (industrial group with €3 billion in revenue vs. small company with €8 million in revenue).

Results

Successful completion of the transaction within four months with satisfied buyer and seller. The management of Harald Zahn GmbH remains on board and is driving the integration.
