Changes in management at components subsidiary Tridonic
Dornbirn, Austria – Changes are taking place in the management team of the Zumtobel Group's components business (Tridonic brand): Tridonic CEO Walter Ziegler and COO Rüdiger Kofahl are to leave the company at the end of January. For an interim period, the Chairman of the Management Board of Zumtobel AG, Harald Sommerer, will be taking charge of the management of Tridonic in addition to his role as Group CEO, working closely with Tridonic CFO Werner Blum. Executive search measures are being initiated to fill the two vacancies.

Walter Ziegler joined the Group in 1989 as Managing Director of Tridonic's German sales company and in 1997 assumed the role of Tridonic CEO. Under his leadership, Tridonic advanced to become one of the world's leading suppliers of lighting components. Rüdiger Kofahl has been Tridonic COO since 2007, responsible for Production, Quality Management, Supply Chain, Logistics and Product Development.

"We owe a great debt of gratitude to Walter Ziegler for his outstanding achievements and great personal commitment. During his 22 years with the Tridonic company he has made a great contribution to the international establishment and expansion of our components business. Our thanks also go to Rüdiger Kofahl for his achievements in developing a global, flexible production network, establishing standardised production processes and improving our patent position," commented Zumtobel Group CEO Harald Sommerer.

"In view of the technology shift to LEDs, Tridonic is today facing some major strategic decisions. Based on its excellent customer relations, broad product portfolio and technological expertise, we can see great potential for Tridonic to strengthen its position as innovation leader in this dynamic market environment. In future, the corporate knowledge base in the areas of semiconductor technology and electronics will be more important than ever. So the technology shift is having a substantial impact on all key business processes, as well as on the requirement profile facing top management," said Sommerer, explaining the management changes.

Tridonic GmbH & Co KG is a wholly-owned subsidiary of Zumtobel AG. In the components segment, Group sales in the 2010/11 financial year totalled EUR 437.3 million.
