Why Siemens Is Combining Four Automation Units

Siemens plans to bring four Digital Industries units together on October 1, 2026. For manufacturing customers, the intended benefit is more coordinated access to automation equipment and support. For Siemens, the larger bet is that connecting its hardware with software, services and industrial AI will create more valuable offerings—and eventually improve returns. 92

What changes for manufacturers?

The new Automation business will combine Customer Services, Factory Automation, Motion Control and Process Automation. Rainer Brehm has been appointed to lead it. Bringing these functions under one organization is intended to reduce the need for customers to navigate separate Siemens teams when coordinating production technology and ongoing support. That simpler experience is the goal; the merger has not yet taken effect. 49

Why combine hardware, software and AI?

The commercial logic is to connect sales, technology and industrial data that have sat in separate units. Siemens wants software and AI to add value to its physical automation products, rather than treating them as disconnected offerings. Its broader objective is more flexible and productive manufacturing systems. 26

Siemens’ acquisitions of Altair and Dotmatics fit that approach by expanding its software portfolio. Industrial data is another potential advantage: Busch has emphasized the volume of data generated by factories and other operations as a resource for AI. Turning those assets into useful, integrated products will depend on execution, not simply on placing the businesses under one management structure. 735

Will the plan close Siemens’ margin gap?

Higher-value software and AI offerings could help Siemens pursue stronger margins. Reporting on the overhaul describes closing a gap with higher-margin rivals as an ambition, not an outcome. The reorganization alone cannot demonstrate that Siemens has narrowed that gap; customers would need to adopt the combined offerings and the financial benefits would need to show up over time. 25

One report also describes a planned Seattle AI hub as part of Busch’s wider push. The available sources do not establish its operating plans or quantify a narrowing valuation discount, so neither should be treated as evidence that the strategy is already paying off. 7
