Press Release: TIC Holding Schweiz / Winterberg acquire TransGeo AG
TIC Holding Schweiz AG, a buy‑build‑and‑technologize platform financed by Winterberg Investment X and managed by Winterberg Advisory GmbH, has acquired TransGeo AG, headquartered in Gümlingen near Bern, Switzerland.
Baar, Switzerland – September 2025
TransGeo AG, based in Gümlingen near Bern, an accredited testing laboratory in construction materials testing and advisory services, became—effective retroactively as of 1 January 2025—a member of TIC Holding Schweiz AG. The company will continue to operate as an independent testing laboratory within TIC Holding Schweiz. This step broadens TransGeo’s base and enables it to further expand its areas of activity. It also provides an optimal succession solution for the previous majority shareholder, chairman of the board and chief executive officer, Christian Wyss.
Going forward, Christian Wyss will focus on his duties on the board of directors and ensure that operational management is handed over to long‑standing employee Folco Giacomini by the end of 2026. This process will also be supported by long‑standing employee and board member Dagmar Riesen. As the new chairman of the board, Fabian Kröher—also chairman of TIC Holding Schweiz and a Partner at Winterberg—will champion an entrepreneurial culture and the adoption of the latest technologies in construction materials testing across all corporate functions to drive sustainable, continuous development.
Commenting on the transaction, Christian Wyss said: “I believe that with these measures we have found an optimal solution for all stakeholders. We look forward to continuing our long‑standing and successful collaboration with our corporate clients and partners—nothing changes for them: all familiar points of contact remain in place and our examinations will continue to be performed with the highest reliability. Personally, I am very pleased that TransGeo can continue to develop successfully as an independent company, and I will keep supporting this with my full commitment.”
Fabian Kröher added: “With TransGeo, we have found the perfect addition to TIC Holding Schweiz AG in the field of construction materials testing. The company enjoys an excellent reputation; it is valued not only for its accredited testing, but also for its competent advice on geological issues, and it maintains very strong customer relationships. We are delighted to support the company’s further development together with the entire team within TIC Holding Schweiz.”
Winterberg is actively seeking add‑on acquisitions in Switzerland in the sector of accredited testing and calibration services—particularly in the areas of construction and infrastructure as well as in industrial metrology and testing. To this end, Winterberg is in active discussions with a number of additional companies.
