We close deals - Carlsquare advises Aéro Solutions SAS on the sale to DPE portfolio company Massenberg

Aéro Solutions (Oberhausen/Saint Dizier/Haarlem) joins the Massenberg Group (Essen). With the second acquisition within one year, the Massenberg Group complements its portfolio of building maintenance with the attractive service of repairing natural draft and cell cooling towers and thus is driving forward the international expansion with locations in France, BeNeLux and Eastern Europe.

Founded in 2013, Aéro Solutions is one of the leading specialist companies in Europe for demanding maintenance work on cooling towers in the energy and industrial sectors, with around 30 employees. Sebastian Thielkes, founder and CEO of Aéro Solutions, will continue to manage the company and shape the strong growth of previous years into the future.

Massenberg and Aéro Solutions, both industry leading experts in their market segments, complement each other perfectly with their services: With Aéro Solutions, the Massenberg Group is expanding its service portfolio to include the repair of natural draft and cell cooling towers, thus offering its customers in Germany and France even more expertise from a single source. As a result of the transaction, the Massenberg Group is growing to more than 450 employees at 15 locations in three countries and remains on course for expansion.

Sebastian Thielkes adds: “We had a good feeling about the merger right from the start and are very much looking forward to working together with Massenberg. It is also a great sign to our employees: Aéro Solutions is now taking the next step in its business development and can continue the growth of the past with a strong partner. Carlsquare has supported us in this process with its high level of market expertise within a structured process and has identified the perfect partner with DPE and Massenberg”.

The growth investor DPE, which focuses on medium-sized businesses, had acquired a stake in Massenberg in June 2019 together with Heiner Stahl, CEO of the Massenberg Group. The declared goal: to create a leading group of companies through organic growth, acquisitions and partnerships in the highly fragmented building maintenance sector and to actively promote the consolidation process in the market by acquiring additional specialists such as Aéro Solutions and regional market companions.

Mark Suderow, Investment Director at DPE, adds: “DPE publicly stated months ago that we will continue to invest in growth during Covid-19. We stand by that. A cross-border transaction at this point in time is of course a special treat and an enormous success for the management. We will continue to follow this path consistently and look forward to further discussions with entrepreneurs from the industry”.

Carlsquare acted as exclusive financial advisor to Aéro Solutions.
