5 years (current)
Key Decisions & Impact
Busch, who holds a doctorate in physics, joined Siemens in 1994 and rose through corporate research and development, automotive technology, process management, and corporate strategy roles before succeeding Joe Kaeser as CEO in 2021. He has continued Siemens' software-driven strategy, overseeing the roughly $10 billion Altair Engineering acquisition in 2025 to deepen the company's simulation and AI-design capabilities.
Legacy
Under Busch, Siemens grew FY2025 revenue to EUR78.914 billion (up from EUR74.882 billion in FY2023) while continuing to shift the company's profit mix toward higher-margin industrial software. Under his leadership Siemens has also expanded partnerships in industrial AI, positioning the Xcelerator software platform as a foundation for AI-driven factory and infrastructure design. He has also overseen Siemens' continued exposure to China, a market that remains simultaneously one of the company's largest revenue sources and a source of geopolitical risk given rising trade tensions between China and Western economies during his tenure. He has framed Siemens long-term strategy around being a technology partner for both the energy transition and industrial digitalization simultaneously, rather than choosing between the two priorities.
