With her extensive financial expertise, Claudia Schmitt has shaped the financial management of the Group and has prudently steered Siltronic’s financial stability following several years of substantial growth investments. The Executive Board team is navigating the current economic challenges with foresight and has strengthened the company’s resilience through targeted cost and liquidity measures. I am very pleased to continue our trusted collaboration with this exceptionally well-coordinated team.”

Dr. Michael Heckmeier commented: “I am grateful to the Supervisory Board for the trust they have placed in me. Together with my Executive Board team and our highly motivated employees, we will continue to drive Siltronic AG’s successful development – with a clear focus on preparing for the next phase of growth.” Claudia Schmitt added: “I too am very much looking forward to contributing to Siltronic AG’s strong financial performance and value creation for another five years.”
