What is the largest German mechanical engineering company in 2025?

What is the Highest-Revenue German Mechanical Engineering Company in 2025?

Short and clear: Siemens. The technology group headquartered in Berlin and Munich is, with its industrial core business (automation, digitalization, electrification, mobility, and medical technology), according to the available figures and ResearchGermany’s market research, the largest German machinery company.

To put the scale into perspective: Siemens generated €75.93 billion in revenue in fiscal year 2024 (continuing operations). Already in 2023, reported group revenue stood at €92.305 billion. This places Siemens clearly ahead of other major German machinery players.

Why Siemens Leads

Although Siemens is a conglomerate, the largest revenue blocks come from segments central to mechanical engineering: Digital Industries (automation & industrial software), Smart Infrastructure (electrification & building technology), Mobility (railway technology), as well as the majority-owned Siemens Healthineers. This breadth and depth make Siemens in 2025 the highest-revenue industrial provider with a direct mechanical engineering focus.

• Siemens (continuing operations) 2024: €75.93 billion revenue
• Siemens Group 2023: €92.305 billion revenue

Comparison: Selected German Mechanical Engineering Companies (Revenue 2023)

The gap is clear in direct comparison. The following companies are among the relevant machinery players in Germany – but their 2023 revenues are significantly below Siemens.

• KION GROUP AG (forklifts & warehouse technology): €11.434 billion
• ANDRITZ Schuler GmbH (forming technology/presses; ANDRITZ Group): €8.660 billion
• GEA Group (food & process machinery): €5.469 billion
• Exyte GmbH (cleanroom/high-tech manufacturing): €5.042 billion

Classification: “Machinery” vs. Conglomerate

Siemens is not a “pure” single-segment machinery company, but a broadly diversified industrial group. This very structure, however, is highly relevant in mechanical engineering:

• Automation & Software: From PLC to PLM/EDA – decisive for engineering speed and factory productivity.
• Electrification & Building/Grids: Power distribution, protection and switching technology, building software – essential for factories, data centers, and test facilities.
• Mobility: Rolling stock, signaling technology, and services – indirectly important for production and logistics infrastructure.
• Medical Technology: Mechatronics and high-tech manufacturing expertise with stable, industry-based value chains.

Outlook 2025: Machinery-Relevant Drivers in the Siemens Group

The 2024 segment reports outline what will matter in 2025: software remains a growth driver, automation normalizes over the course of the year, electrification and data centers remain strong, and mobility benefits from continued high demand.

• Digital Industries: Software grew double digits; automation in H1 2025 still in inventory reduction, recovery expected from H2 (order backlog DI at end FY24: €9 billion, ~€6 billion of which for 2025).
• Smart Infrastructure: 2024 revenue €21.368 billion; strong demand from power distribution/data centers, robust outlook for 2025.
• Mobility: 2024 revenue €11.420 billion; high order backlog (€48 billion, ~€11 billion for 2025) ensures visibility.
• Siemens Healthineers: 2024 revenue €22.362 billion; stable industrial cash and technology contributor.

Conclusion

Based on the available revenue and segment data, Siemens remains in 2025 the highest-revenue German mechanical engineering company – understood as an industrial anchor with the business areas relevant to mechanical engineering. Pure machinery specialists such as KION, GEA, Exyte, or ANDRITZ Schuler are significantly lower in terms of revenue.
