At the same time, we are pleased to appoint with Dimitrij Lisak an internal successor who is well prepared for the CFO responsibility."

Oliver Wyrsch, Chief Executive Officer of INFICON Holding AG, added: “I would like to sincerely thank Matthias for his leadership and impact. He has been the rock I could always rely on. Over the past year, I have worked closely with both Matthias and Dimitrij and I got the conviction that both will ensure a smooth and seamless handover.”
