Gerresheimer CEO Dietmar Siemssen will step down after profit warnings and regulatory scrutiny. Uwe Roehrhoff named interim CEO.
(Reuters) -Medical equipment maker Gerresheimer is parting with its chief executive Dietmar Siemssen at the end of the month, the company said on Tuesday.
Siemssen will step down as CEO on October 31 by mutual agreement with the supervisory board, according to a statement, which did not give a reason for his departure.
The decision follows several profit warnings, the launch of an investigation by Germany's financial regulator over suspected accounting rule violations and a halving of the share's value since January.
Uwe Roehrhoff has been appointed interim CEO effective November 1, the statement said.
A Gerresheimer spokesperson told Reuters that the company had started the search for a new CEO, and that Roehrhoff would stay in his position for "as long as it takes".
Roehrhoff, a Gerresheimer veteran, already served as CEO from 2010 to 2017 and held various management positions in the company from 1991 to 2017.
His appointment follows a series of changes in Gerresheimer's management board in recent months.
The company announced in September Wolf Lehmann as new CFO and in August Achim Schalk as new head of its moulded glass, tubular glass and syringe systems business units.

A supervisory board is a body of elected or appointed members that oversees the activities of a company, ensuring that the company is managed in accordance with its goals and legal obligations.
A profit warning is a notification issued by a company to inform investors that its earnings will be lower than expected, often due to unfavorable market conditions or operational challenges.
