Under the umbrella of the Portfolio Companies, Siemens has bundled several units, which have been operating independently since April 1, 2019. The eight Portfolio Companies employ around 25,000 people. They currently generate approximately €5 to €6 billion in revenue. The units are agile and flexible; they are 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.
