Siemens Energy’s €158 Billion Rally Hinges on a Single Question: Can Gamesa Keep Up?

Siemens Energy surges with €17.75B orders and doubled cash flow target, but wind unit Gamesa's path to break-even by 2026 remains critical for sustained momentum.

The numbers coming out of Siemens Energy this spring are the kind that reshape an entire sector. A quarterly order intake of €17.75 billion. A free cash flow target nearly doubled to €8 billion. A market capitalisation that has swelled to €158 billion, making it Germany’s third-most-valuable listed company behind only SAP and Volkswagen. The stock closed Friday at €188.00, matching its 52-week high and extending a year-to-date gain of roughly 53%.

Yet for all the euphoria, a single unresolved question hangs over the narrative: Can Siemens Gamesa finally stop being a drag on the group?

The Grid Machine Keeps Grinding

The engine behind this historic run is unmistakable. Grid Technologies, the division sitting at the heart of the artificial intelligence infrastructure boom, is forecast to deliver 25 to 27 percent revenue growth this fiscal year with an operating margin of 18 to 20 percent. Gas Services is running close behind, with orders climbing 32 percent in the second quarter. Together, these two businesses are absorbing the insatiable electricity demand from data centres powering AI workloads.

The management’s revised guidance for fiscal 2026 reflects that momentum. Comparable revenue growth is now seen at 14 to 16 percent, up from the previous 11 to 13 percent range. Net income is expected to land at roughly €4 billion. The free cash flow before taxes projection of around €8 billion represents a dramatic upgrade from the earlier €4 billion to €5 billion target.

Analysts have responded in kind. Deutsche Bank lifted its price target to €195, while JPMorgan and RBC both set theirs at €200. All three maintain buy ratings, arguing that structural tailwinds outweigh any temporary currency headwinds.

Gamesa: Still Healing, But Healing

The wind turbine subsidiary has been the group’s persistent headache, but the latest numbers offer genuine cause for optimism. Siemens Gamesa’s operating loss narrowed to €44 million in the second quarter, down sharply from €249 million a year earlier and well ahead of the €74 million loss analysts had pencilled in. Management is sticking to its target of reaching operational break-even by the end of fiscal 2026.

That timeline is critical. The entire growth story — the cash flow explosion, the record order book, the share buyback programme — rests on the assumption that Gamesa stops bleeding. If it does, the group’s credibility is reinforced. If it doesn’t, the doubters gain ammunition.

The activist investor Ananym Capital is already pushing for a full separation of Gamesa, arguing that the profitable core businesses would unlock their true value without the drag. So far, institutional shareholders including DWS and Union Investment are backing management’s approach. But the pressure will only intensify if the May 12 full-year report shows any stumbles.

Buybacks and Backlash

Siemens Energy is deploying its growing cash pile aggressively. A €2 billion share buyback programme launched on March 4 is running through September 2026, with nearly 9.5 million shares already repurchased. That is the first tranche of a larger plan that could return up to €6 billion to shareholders by the end of 2028.

The activist campaign adds a layer of tension. Ananym Capital wants faster action, while the board is pursuing a more gradual path. The May 12 report will be the next battleground, as the full quarterly figures must confirm the preliminary numbers across all segments — and the cash flow forecast must hold.

Tariff Risks Look Manageable

One potential cloud on the horizon is US import tariffs, but Siemens Energy appears well insulated. With 28 production sites in the United States, the company can absorb most of the impact. Management expects tariff-related additional costs in fiscal 2026 to be in the low triple-digit millions — a manageable figure given the scale of the business.

What May 12 Will Reveal

The full second-quarter report on May 12 is the next major inflection point. Investors will be watching for three things: confirmation of the cash flow guidance, the trajectory of Gamesa’s recovery, and any updates on the buyback pace. The preliminary numbers have set the bar high. Now the market needs to see them backed up by detailed segment data.

For Siemens Energy, the rally has been extraordinary. But the story is not yet complete. The grid business is firing on all cylinders, the cash pile is growing, and the wind division is finally showing signs of life. Whether that is enough to sustain the current valuation — or whether Gamesa will once again become the anchor — is the question that will define the next chapter.
