Veronika Bienert will become Chief Financial Officer of Siemens AG on April 1, 2026, succeeding Prof. Dr. Ralf P. Thomas. Bienert is currently responsible for the Service Portfolio of Siemens Financial Services, Siemens Real Estate, and Global Business Services. The planned change in leadership was first announced in November.
Ralf Thomas will leave the Managing Board at his own request on May 13, 2026, but will remain as a special advisor to both the Supervisory Board and the Managing Board until December 2026, when his regular term ends. He will continue as Chairman of the Supervisory Board of Siemens Healthineers AG.
Peter Koerte, currently a member of the Managing Board as well as Chief Technology Officer and Chief Strategy Officer, will take over responsibility for Smart Infrastructure from Matthias Rebellius starting July 1, 2026. Koerte will hold this new role in addition to his current duties. Matthias Rebellius has decided to step down from the Managing Board at the end of his term; he is also CEO of Siemens Smart Infrastructure.
Jim Hagemann Snabe, Chairman of the Supervisory Board of Siemens AG, commented: “With these decisions, the Supervisory Board is ensuring orderly and smooth succession planning for the Managing Board and setting the course for the next phase of our transformation into ONE Tech Company. I would like to congratulate Veronika Bienert and Peter Koerte on their new responsibilities, and I am convinced that they will continue to drive the company forward with their multifaceted experience, competence and leadership.” He added: “My special thanks go to Ralf Thomas for his active support in the selection and onboarding of his successor as well as for his clear leadership and strategic foresight, which have contributed significantly to the company’s current position of strength. I would also like to thank Matthias Rebellius for the impressive successes of Smart Infrastructure in recent years. Until the end of this fiscal year, he will continue to advance and accelerate the implementation of ONE Tech Company.”
Roland Busch, President and CEO of Siemens AG [source], said: “I would like to express my sincere thanks to Ralf Thomas – for his extraordinary achievements and the extremely good and trusting cooperation. Siemens’ impressive financial strength clearly bears his signature. In a few weeks’ time, as planned, Veronika Bienert will take over full responsibility in her new role, bringing with her the experience of an outstanding financial expert and entrepreneur. I congratulate her and look forward to the work ahead. I would also like to thank Matthias Rebellius, who has written a great success story in recent years – one that Peter Koerte will carry forward with his deep technological and strategic experience and comprehensive knowledge of the portfolio and customer landscape.”
Peter Koerte stated: “I would like to thank the Supervisory Board for the trust it has placed in me. Matthias Rebellius and the Smart Infrastructure team have set a high bar in recent years, and I look forward to build upon their successful work and contribute even further to the success of our customers through innovative, digital and forward-looking solutions.”
Following these changes, which are part of ongoing succession planning efforts by Siemens’ Supervisory Board [source], there will be five members on Siemens AG’s Managing Board instead of seven.
