Siemens Energy: The AI Infrastructure Play That Markets Haven't Priced in Yet
11.06.2026 - 20:23:05 | boerse-global.de
When investors think about artificial intelligence, they usually picture Nvidia's chips or sprawling desert data centres. A much more basic question gets overlooked: where will the electricity come from, and who will build the grids to handle it? Siemens Energy has become the answer to that question — yet the stock is still trading well off its highs, caught between record orders and lingering doubts over its wind turbine division.
The company's second fiscal quarter of 2026 told a story of explosive demand. Order intake hit €17.7 billion, a near-30% jump from a year earlier, and the book-to-bill ratio stood at 1.72. The total order backlog swelled to €154 billion. Siemens Energy is winning business faster than it can deliver, an enviable position that is rare in industrial history.
The real engine of that growth is Grid Technologies. The division, which supplies transformers, switchgear and high-voltage direct current transmission equipment, now expects revenue to expand by 25 to 27% in fiscal 2026, up from a previous forecast of 19 to 21%. Margin before special items has also been upgraded, to between 18 and 20% compared with an earlier 16 to 18%. Such a significant mid-year upgrade at the division level underscores just how tight the market for grid equipment has become. Data centres alone accounted for roughly a quarter of Grid Technologies' orders in the first quarter, and the broader push from electric vehicles, heat pumps and renewable energy is straining networks across the globe.
Gas turbines are also selling fast. Commitments already stand at 87 GW, and management expects that to hit 90 to 100 GW by year-end. The group as a whole now forecasts 14 to 16% revenue growth for 2026, up from 11 to 13%, with a margin of 10 to 12% and net income of around €4 billion. Free cash flow before tax is projected at roughly €8 billion.
Should investors sell immediately? Or is it worth buying Siemens Energy?
That cash is being put to work. Siemens Energy is in the middle of a €6 billion share buyback programme running through 2028. Since March, it has repurchased about 11.6 million shares at an average price of €157.10, meaning the first €2 billion tranche is nearly complete. It is a striking pivot for a company that just a few years ago was leaning on state guarantees.
Yet the stock remains subdued. After hitting an all-time high of around €196 in April, the shares corrected roughly 25% before staging a partial recovery. On the day covered here, they climbed 5.7% to €145.80 — a welcome bounce but still far from the peaks. The average analyst target sits near €195, implying substantial upside, and 19 out of 21 analysts rate the stock a buy. The valuation, at a price-to-earnings multiple of roughly 59, is undeniably rich and leaves little room for execution missteps.
That is where Gamesa comes back into the picture. The wind turbine subsidiary remains the company's Achilles heel. In fiscal 2026, Gamesa is expected to grow revenue by just 3 to 5% and achieve only a breakeven margin. Activist hedge fund Ananym Capital is pushing for a spin-off. CEO Christian Bruch has rejected that idea, insisting on an operational turnaround instead. The risk is that Gamesa continues to overshadow the strong results from Grid Technologies and gas turbines. If the division can at least stop being a drag, the market could start to value the structural growth story far more directly.
Siemens Energy at a turning point? This analysis reveals what investors need to know now.
The broader tension in the clean?energy sector — operational strength coexisting with share?price weakness — is especially acute for Siemens Energy. Next catalyst will come on 5 August with the third?quarter earnings release. Until then, the buyback programme and management roadshows are the primary signals. The fundamental tailwind from AI, electrification and grid modernisation has rarely been stronger. For Siemens Energy, the challenge is no longer about demand. It is about whether the market can look past Gamesa long enough to see the infrastructure giant underneath.
