German industrial conglomerate headquartered in Munich. Siemens began dismantling its conglomerate structure under Joe Kaeser, chief executive from 2013 to 2021. In 2017 it spun out Healthineers, its medical-equipment division, as a separate listed company. It did the same with its energy arm in 2020. Its stake in Siemens Energy has since fallen to 10%. Roland Busch, Mr Kaeser's successor, wants Siemens to become a focused industrial-technology company.
The Siemens factory in Amberg, Bavaria, which makes 1,500 variants of machine controllers, produces around 20 times what it did when it opened in 1989, with approximately the same number of workers. In 2025 Siemens bought Altair, an industrial-software firm, for $10bn—its largest acquisition ever. Software now accounts for a third of sales in its industrial-automation division. In September 2025 Siemens announced a deal with German machine-makers to pool anonymised data from their hardware and build AI models for industrial use. On January 6th 2026 it expanded its partnership with Nvidia to develop, among other things, an AI-powered tool for building digital twins.
Peter Koerte, Siemens's chief technologist, has said that AI will become the "brains" of factories much as machines have become their "muscles."
When God endowed human beings with brains, He did not intend to guarantee them.
