Industrial automation & power · data-center power engine (Smart Infrastructure)
Siemens AG
Europe's largest industrial group spans factory automation (Digital Industries), power infrastructure (Smart Infrastructure) and rail (Mobility), but this node's crux is that the center of gravity of profit has moved from automation to power — AI-data-center power demand lifted transformer/switchgear demand and pushed Smart Infrastructure's margin to 19.6%, while the traditional leader Digital Industries was pressed by destocking to a 14.9% margin (from 18.9%). FY2025 (ended Sep 2025) revenue €78.9bn (+4%) and net income €10.4bn (+16%) set a record for a third straight year. In parallel, separating Energy (~10% residual) and Healthineers (deconsolidation planned) to simplify toward the industrial core, while widening its high-margin software axis via EDA and Altair, is the re-rating axis.

Revenue from
- Smart Infrastructure customers (data centers, grid, utilities) High confidence· Revenue 23 EUR_bn · FY2025 ended Sep2025
As AI data centers devour power, Smart Infrastructure has become Siemens' profit engine — FY2025 revenue €23.0bn (+8%), profit €4.5bn, a 19.6% margin (+2.3pp), the group's best profitability. It supplies transformers, switchgear, distribution and building tech to hyperscalers and utilities but does not disclose customer names, so they stay anonymous. Demand running ahead of capacity — a supplier-favored phase — is what drove the margin.Mentions EN JPMorgan·UBS (via ad-hoc-news) Published Jun 30, 2026: Siemens gets fresh analyst targets — JPMorgan OW €345, UBS Buy €310Confirms KO AI Times (KR) Published Mar 1, 2026: AI data-center buildout reshapes power infrastructure — Siemens 800V DC solutionConfirms EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025) - Digital Industries customers (factory automation, industrial software) High confidence· Revenue 17.8 EUR_bn · FY2025 ended Sep2025
Once Siemens' crown, factory automation was pressed by a destocking cycle — FY2025 revenue -4% and margin falling from 18.9% to 14.9%. But orders turned up +8%, and software — EDA (chip design), PLM, simulation (Altair, Dotmatics acquisitions) — is the structural growth axis inside the hardware weakness.

Rail rolling stock, signaling, infrastructure and services delivered FY2025 revenue of €12.4bn (+9%), but at an 8.8% margin — the thinnest in the group. A long-cycle, low-margin business whose orders swing hard on large-project timing (a -45% order quarter against a prior-year spike); a stable backlog gives revenue visibility while profitability stays structurally low.Confirms EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025)
Pays to
- Power-equipment materials (copper, electrical steel, insulation, components) Medium confidence
The cost of transformers, switchgear and distribution boards sits in copper, electrical steel (grain-oriented silicon steel), insulation and castings — in a data-center-driven demand surge, the supply and price of these materials govern Smart Infrastructure's margin and lead times, and grain-oriented electrical steel is globally tight.Mentions EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025) - Automation electronics & semiconductors (external procurement) Medium confidence
Siemens buys the semiconductors and electronic components that go into automation hardware (PLCs, drives, controllers) — it sits upstream of the chip-design ecosystem via its own EDA software yet depends externally on the chips for its own products, so component availability acts directly on Digital Industries' lead times and cost.Mentions EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025)
Investments
- Siemens EDA (semiconductor design software subsidiary) High confidence· ownership 100%
The electronic design automation (EDA) subsidiary secured via the 2017 Mentor Graphics acquisition and a core of Digital Industries Software — one of the EDA big three behind Cadence and Synopsys. For Siemens it is a high-margin, structurally growing software holding decoupled from the automation-hardware cycle, and with Altair and Dotmatics it widens industrial-software/AI leadership.Confirms EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025) - Siemens Healthineers (~69%, deconsolidation planned) High confidence· ownership 69%
Siemens consolidated its medical-imaging/diagnostics subsidiary Healthineers at ~69% at FY2025-end (revenue €23.4bn), but in November 2025 announced it will spin off 30% to shareholders to deconsolidate and, over the medium term, cut the holding to a minority/financial asset — after Energy, the final act of a portfolio simplification concentrating on the industrial core (automation, infrastructure, mobility).Confirms EN Siemens AG Published Nov 13, 2025: Siemens Earnings Release Q4 FY2025 (year ended Sep 30, 2025) - Siemens Energy (~10% residual stake) High confidence· ownership 10%
A financial-asset stake of ~10% in Siemens Energy (spun off in 2020; further tranches transferred to Siemens' pension trust) — as Energy's stock soared on grid and AI power demand, the residual stake is worth ~€25bn. Siemens is gradually monetizing it to redeploy capital into the core and shareholder returns, a symbol of portfolio simplification.

Siemens' thesis is 'a shift of axis from the automation crown to the power engine, plus portfolio simplification.' AI-data-center power demand turned Smart Infrastructure into a 19.6%-margin profit engine, while Digital Industries was pressed by automation destocking but is supported by an +8% order rebound and EDA/PLM/Altair software growth. FY2025 net income of €10.4bn (record for a third straight year) and a 1.12 book-to-bill give revenue visibility. The company is separating Energy (~10%, ~€25bn) and Healthineers (~69%, deconsolidation planned) to redeploy capital into the core and returns — this simplification is the catalyst to unwind the conglomerate discount. Risks are a delayed automation recovery and material bottlenecks (e.g., electrical steel) at Smart Infrastructure. In the graph the ripple runs AI capex → data-center power (Smart Infrastructure, parallel to Schneider, ABB, Eaton) → upstream materials (copper, electrical steel), and into chip design via subsidiary Siemens EDA (fabless/foundry customers such as TSMC and Nvidia).
