Reinhausen Honored Once Again as a “Best Managed Company”
Reinhausen has been named a Best Managed Companies Award winner for the third consecutive year. At the award ceremony on May 21, 2026, at the Gesellschaftshaus Palmengarten in Frankfurt am Main, Holger Michalka and Dr. Manuel Sojer accepted the honor on behalf of the Regensburg-based family business. Presented by Deloitte Private, UBS, Frankfurter Allgemeine Zeitung, and the Federation of German Industries (BDI), the award recognizes mid-sized companies that excel across four distinct evaluation dimensions.
The Best Managed Companies Award is an international seal of quality for outstandingly managed mid-sized companies. Launched by Deloitte in Canada in the 1990s, it is now established in more than 45 countries. Winners are selected by a jury on the basis of written applications and multi-hour in-person interviews, in which the companies are assessed in depth on strategy, innovative strength, leadership culture, and financial robustness.
The award recognizes companies that take responsibility toward the market, their employees, and society, and that think long-term — even in uncertain times. Reinhausen convinced both the jury and the panel of experts in all four evaluation dimensions: strategy; productivity and innovation; culture and employee engagement; and finance and governance.
This year’s recognition comes in a significant year for Reinhausen. In 1926, Bernhard Jansen filed the patent for the high-speed resistor switch. This invention laid the foundation for the development of the on-load tap-changer, which to this day remains the basis of the company’s business model and, at the same time, a technical prerequisite for the worldwide interconnection of power grids.
“This award belongs to our employees around the world. It shows that long-term thinking and our independence as a family business pay off. Especially in our anniversary year, this is a powerful signal. It motivates us to keep advancing the energy transition with reliable solutions,” says Holger Michalka, Managing Director of Reinhausen, who accepted the award in Frankfurt.
Reinhausen sees itself as a systems provider driving the digitalization of electrical power engineering in a traditionally conservative technology environment. Through a global network of service and logistics, the company stays close to its customers worldwide.
“Best Managed Companies like Reinhausen set the standard in terms of agility and resilience: they respond quickly to multiple changes and understand transformation as a mandate to shape the future. Reinhausen acts with a confidence that provides orientation — today more than ever,” says Dr. Christine Wolter, Partner at Deloitte and Lead Deloitte Private.
