mdexx Holding GmbH

As a stand-alone company the mdexx group develops and produces transformers, power supplies, throttles and filters, as well as axial and radial ventilators, especially for the rail sector but also for the medical technology sector. In 2016 CGS Management, a Swiss private equity firm, sold off the former business division of Siemens AG – 100% of the shares were acquired by Quantum Capital Partners.

The new investors identified growth and upside potential for the company with its nearly 500 emloyees in Germany, Czech Republic, and China. Attracting third party customers besides Siemens and addressing operational inefficiencies brought about a quick turnaround for mdexx.
