Supervisory Board appoints Claudia Schmitt as CFO of Siltronic AG to succeed Rainer Irle

Munich, March 30, 2023 – Claudia Schmitt will become the new CFO of Siltronic AG effective July 1, 2023. This was decided by the Supervisory Board at its meeting today. She succeeds Rainer Irle (53), who has been CFO of Siltronic AG since 2013 and will leave the company at his own request. Claudia Schmitt (51) will initially be appointed for three years.

"We are very pleased to introduce Claudia Schmitt as an experienced successor to Rainer Irle from Siltronic's own ranks," said Dr. Tobias Ohler, Chairman of the Supervisory Board of Siltronic AG. "Claudia Schmitt has already contributed to Siltronic's profitable growth for more than 13 years and has many years of extensive financial experience for her new Executive Board role. Most recently, she was Head of Controlling and Treasury at Siltronic AG."

"We would like to thank Rainer Irle very much for his excellent work at Siltronic. Over the past 10 years, he has made a significant contribution to the company's growth and, among other things, supported Siltronic AG's successful IPO in 2015," Tobias Ohler continued.

"With Claudia Schmitt, an excellent choice was made as successor to my Executive Board colleague Rainer Irle. I have appreciated working with her for many years as a brilliant colleague and could not imagine a better successor," said Dr. Christoph von Plotho, CEO of Siltronic AG.
