Under the umbrella of the Portfolio Companies, Siemens has bundled several units which operate independently since April 1, 2019. The nine Portfolio Companies employ around 22,500 people. In fiscal year 2018 they generated about €5 billion in revenue. The units operate agile and flexible: decentralized, with fast decision making and reaction times. This enables them to be more competitive in their respective markets with more focus on their customers. The Portfolio Companies are led by CEO Jochen Eickholt.
