Drillisch has confirmed a series of management and supervisory board appointments following its merger with 1&1 Telecommunication.
The two companies completed the deal last month, and Ralph Dommermuth (left) has been appointed CEO.
Dommermuth founded 1&1 in 1998 and has been CEO of its parent United Internet since a restructure in 2000.
He will take over the reins at Drillisch, now owned by UI due to the terms of the merger, on 1 January 2018.
Dommermuth is joined on the management board of Drillisch by 1&1 CEO Martin Witt.
Executive-Board Spokesman Vlasios Choulidis, who also serves as Director of Sales, Marketing and Customer Care, is leaving the business on 31 December.
However, he is likely to put himself forward as a candidate for the supervisory board at the next general meeting, the company said.
Meanwhile, Drillisch’s supervisory board has been boosted by the arrival of three new members.
Kurt Dobitsch, Kai-Uwe Ricke and Michael Scheeren started their new roles yesterday (16 October), and replace Susanne Rückert, Frank Rothauge and Bernd H. Schmidt, who have all resigned.
All three new arrivals are members are on the supervisory board of 1&1, while Dobitsch has also served as chairman of the supervisory board of UI.
Drillisch supervisory board Chairman Marc Brucherseifer said: "In addition to their comprehensive expertise and specific knowledge of the group, all three new members will also bring to the supervisory board of Drillisch AG their substantial previous and expert knowledge that they have gained about the corporate structure of 1 & 1 Telecommunication SE, which is particularly important for the combination of 1 & 1 Telecommunication SE and Drillisch AG."
The merger sees Drillisch become Germany’s fourth largest operator.
