Siemens Shares Scale Record Peak as Infrastructure Orders and Leadership Shuffle Reshape the Narrative

Siemens shares rise 2% to €278.60 as Smart Infrastructure orders surge 35% to record €7.5B, with new leadership and NVIDIA partnership driving AI data center growth.

Siemens stock hit a fresh 52-week high of €278.60 on Monday, climbing 2.01%, as investors digested a quarterly performance that pairs booming infrastructure and software orders with a key leadership change in the division responsible for intelligent power distribution. The equity has now advanced 15.65% since the start of the year and 29.73% over the past twelve months.

The rally rests on a foundation of heavy demand. Comparable order intake surged 18% to €24.1 billion in the latest quarter, outstripping revenue growth of 6% to €19.8 billion. That dynamic pushed the book-to-bill ratio to 1.22 and swelled the order backlog to €124 billion, giving the industrial conglomerate exceptional visibility into the coming quarters. Under the hood, the industrial business generated €3.0 billion in earnings with a 15.4% margin, while group free cash flow reached €1.7 billion and net profit came in at €2.2 billion.

The standout story was Smart Infrastructure, where comparable orders jumped 35% to €7.5 billion — a quarterly record. Electrification and Electrical Products drove the surge, fueled by large contracts from data center and semiconductor clients, especially in the United States. That unit now has fresh leadership: Markus Grabmeier took over the Business Unit Electrical Products on June 1, 2026, succeeding Andreas Matthé, who is retiring at the end of September after 15 years at the helm. The timing is strategic, as demand for efficient energy infrastructure accelerates alongside the AI boom.

Siemens is doubling down on that opportunity. Together with NVIDIA and Fluence, it has developed a reference architecture for AI data centers, tailored to NVIDIA's DSX Vera Rubin AI factory. The design covers the entire electrical path from grid connection to rack interface, with a total capacity of 136 MW and an IT load of 100 MW. Fluence contributes battery storage to boost flexibility. The aim is to offer hyperscalers and cloud providers standardized, high-efficiency blueprints — a formula that could translate into further blockbuster orders for the Electrical Products unit under Grabmeier.

Digital Industries also delivered. Comparable order intake rose 12% to €4.8 billion, and revenue climbed 8%. The software business grew 14% to €1.6 billion, while segment earnings surged 35% to €857 million, yielding an 18.5% margin. The Siemens Xcelerator portfolio and recent software acquisitions underpinned the first-half digital growth of 19%.

Not every division is humming. Mobility booked a 41% jump in orders to €5.3 billion, but revenue slipped slightly below the prior-year level to €3.0 billion. Segment earnings dropped 28% to €208 million, compressing the margin to 6.9%. Siemens pointed to US tariffs and delayed call-offs from large rail infrastructure contracts as the culprits. The company has trimmed its revenue growth forecast for Mobility to 5-7%, while keeping the margin guidance at 8-10%.

On the capital markets front, Siemens bought back 278,209 of its own shares between May 25 and May 31, 2026. Since the program started in February 2024, total repurchases have exceeded 27.6 million shares — a clear vote of confidence from management.

Looking ahead, the group reaffirmed its full-year targets: comparable revenue growth of 6-8%, a book-to-bill above 1, and earnings per share before purchase price allocation effects of €10.70 to €11.10. Digital Industries now expects 7-10% growth, and Smart Infrastructure 8-10%. With the stock at a record high, the burden of proof falls squarely on execution. Siemens must convert its €124 billion order mountain into margins and cash flow — and ensure that Mobility does not become a permanent drag on the story.
