CGS sells majority stake in Stürtz to capiton

Berlin / Neustadt (Wied) / Pfäffikon SZ, 26. Juli 2021

CGS completes the first exit from the current CGS IV Fund and sells Stürtz Group to German investor capiton. Stürtz has been very successful since CGS came on board in 2017 and has significantly expanded its international presence. The strong growth path is set to continue with capiton as new majority owner.

Stürtz Group, headquartered in Neustadt (Wied), Germany, is a leading manufacturer of machinery and automated solutions for the PVC window production industry. Together with the management team, CGS has pursued an internationalization strategy in recent years with a consistent focus on own sales activities. The company’s market share in the USA has increased markedly and it has expanded its leading position. New branches have been established in Poland, Romania and China to provide direct and local comprehensive sales and maintenance services to customers in the main markets. The product range was also enlarged to include machines for aluminum window production. This has brought substantial overall growth.

Today Stürtz is optimally positioned with an innovative product program, its own control and software solutions and a global service network, to profit from the ongoing trend towards more automated solutions with direct customer support.

Rolf Lanz, Managing Partner at CGS, explained: “We are pleased to have found an experienced investor in capiton as the new owner of Stürtz, thus enabling us to ensure continuity both for employees and customers.” Jonas Bumbacher, Investment Director at CGS, added: “We are very proud of how Stürtz has developed with us. With annual growth of around 10%, many new jobs were created and profitability improved at the same time. Stürtz is now very well-positioned to continue the success story of recent years.”

Christoph Karbenk, Partner at capiton added: “We are glad to welcome Stürtz to the capiton portfolio and we are truly excited to accelerate its international expansion in collaboration with the entire Stürtz team.”

Jörg Breuer, CEO of Stürtz commented: “Development has been highly dynamic in recent years, we achieved a lot thanks to the reliable cooperation with CGS. Now we are looking forward to developing our brand further on a global scale with capiton and continuing the path of growth.”

The transaction remains subject to approval from competition authorities. Sellers and buyers have agreed not to disclose the financial terms of the transaction.
