Siemens AG enters the new trading week with a powerful one-two punch. Its energy subsidiary just nearly doubled quarterly profit and lifted full-year guidance, while the parent company deepened its collaboration with Taiwan Semiconductor Manufacturing Co. on next-generation chip design tools. The stock, which closed Friday at €243.10, has already gained nearly 15% over the past 30 days — and analysts expect the momentum to accelerate.
Energy Unit Delivers a Blowout Quarter
Siemens Energy posted a preliminary net profit of €1.11 billion for its second fiscal quarter, up sharply from €615 million in the same period last year. The outperformance prompted a significant upward revision to the company’s 2026 outlook. Comparable revenue growth is now expected to land between 14% and 16%, compared with the prior forecast of 11% to 13%. The operating margin before special items was raised to a range of 10% to 12%.
The surge is being driven by a structural shift in demand. Gas turbines and grid technologies are benefiting enormously from the buildout of AI data centers in the United States, where electricity consumption is soaring. Since Siemens AG holds a major stake in the energy arm, the operational strength flows directly into the parent’s valuation.
Meanwhile, Siemens Gamesa, the struggling wind power subsidiary, narrowed its loss to a preliminary €44 million from €249 million a year earlier. While not yet a full turnaround, the trajectory is improving.
A Deepening Bet on Chip Design AI
On April 22, Siemens announced an expansion of its partnership with TSMC that goes well beyond routine certification updates. The agreement covers new qualifications for TSMC’s most advanced process technologies, including the 3-nanometer, 2-nanometer, A16, and A14 nodes. Siemens’ Calibre nmPlatform software and Solido simulation suite are now certified for these cutting-edge processes, which are critical for analog, mixed-signal, and RF designs that rely on precise SPICE simulation.
TSMC made clear in its first-quarter report that AI demand will outstrip semiconductor supply for at least two more years. In this environment of scarcity, having certified electronic design automation tools for the latest nodes positions Siemens closer to the bottleneck — and therefore closer to chip customers’ design decisions.
The most strategically ambitious element is Siemens’ Fuse EDA AI system, an agent-based platform designed to autonomously orchestrate semiconductor design workflows. Siemens describes it as domain-specific, tailored to EDA processes rather than a generic AI tool. This is backed by the acquisition of Canopus AI, completed in early January, whose machine-learning technology improves wafer fabrication simulations by measuring edge-placement errors more precisely.
Should investors sell immediately? Or is it worth buying Siemens?
The collaboration also extends into silicon photonics, with Siemens now supporting design and verification of TSMC’s Compact Universal Photonic Engine.
At TSMC’s Technology Symposium 2026, all three major EDA vendors — Siemens, Synopsys, and Cadence — showcased expanded foundry partnerships. Siemens is the smallest of the three by revenue, but market observers say it is pursuing the most aggressive AI architecture strategy.
Finnish Rail Milestone and US Leadership Change
On the mobility side, Siemens completed a landmark order that dates back to 2014. The company delivered the 80th and final Vectron locomotive to Finland’s VR Group — the largest single order ever placed for the platform at the time, and the first deployment on Finland’s broad-gauge network. Siemens Mobility confirmed all units were delivered within the agreed timeframe.
In a personnel move that underscores the importance of the North American market, Mesut Eken will take over as CFO of Siemens USA on August 1. A nearly three-decade veteran of the conglomerate, he most recently led the Motion Control unit.
Broader Context: AI Offensive and Structural Change
The TSMC announcement fits into Siemens’ wider push into industrial AI, which was on full display at Hannover Messe 2026. The company showcased AI solutions spanning the entire value chain, from digital twins to autonomous workflows.
Separately, the conglomerate is preparing to spin off its stake in Siemens Healthineers, with shareholders set to vote on the plan at the annual general meeting in February 2027.
The stock currently trades about 21% above its 12-month low from April 2025. Comparable order intake grew 10% in the first quarter of 2026, and the book-to-bill ratio stood at 1.11 — a clear signal that demand continues to outstrip current delivery capacity.
