At its recent meeting, the Supervisory Board of Siemens AG made decisions regarding the future composition of the Managing Board. These decisions ensure continuity and stability in central management functions and set the course for the next phase in the company’s transformation into ONE Tech Company.
Veronika Bienert, member of the Managing Board, will assume the role of Chief Financial Officer from Prof. Dr. Ralf P. Thomas in addition to her previous duties as of April 1, 2026. That a change would take place at the top of the finance organization was already announced in November. Veronika Bienert is currently responsible for the Service Portfolio of Siemens Financial Services, Siemens Real Estate and Global Business Services. Ralf Thomas will, at his own request, leave the Management Board at the end of May 13, 2026, and will serve as special advisor to the Supervisory Board and the Managing Board until the end of his regular term of office in December 2026. His role as Chairman of the Supervisory Board of Siemens Healthineers AG remains unaffected.
Peter Koerte, member of the Managing Board as well as Chief Technology Officer and Chief Strategy Officer of Siemens AG, will assume responsibility on the Managing Board for Smart Infrastructure from Matthias Rebellius as of July 1, 2026, in addition to his current functions. Matthias Rebellius, member of the Managing Board of Siemens AG and CEO of Siemens Smart Infrastructure, will, at his own request, step down from the Managing Board at the end of his term.
“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,” said Jim Hagemann Snabe, Chairman of the Supervisory Board of Siemens AG. “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,” Snabe continued.
Roland Busch, President and CEO of Siemens AG, says: “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 says: “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.”
With the departure of Matthias Rebellius and Ralf Thomas from the Managing Board of Siemens AG, the Board of Managing Directors will be reduced from seven to five Managing Board members.
