Siemens Energy’s AI-Fueled Order Bonanza Faces Its Toughest Test: Can Gamesa Finally Deliver?

Siemens Energy posts record €146B backlog on AI-driven demand, but stock hinges on Gamesa's breakeven in May 12 report amid activist pressure.

The numbers coming out of Siemens Energy are staggering. The Munich-based industrial group has amassed a record €146 billion order backlog, powered by a surge in demand for gas turbines and grid technology that is directly tied to the artificial intelligence boom. Data centers, hungry for round-the-clock baseload power that renewables alone cannot guarantee, are driving a structural shift in energy procurement. The result: Siemens Energy’s order intake jumped nearly 30 percent to around €17.7 billion in the first half of its fiscal year, with Grid Technologies alone posting a 41 percent increase in orders. The operating margin hit 12.0 percent, beating market expectations, and management has raised its free cash flow target before taxes to roughly €8 billion, up from a previous corridor of €4 billion to €5 billion.

Yet for all the tailwinds in the core business, the stock’s next big move hinges on a single question: Can the troubled wind power subsidiary Siemens Gamesa finally achieve an operating breakeven? The company’s half-year report, due on May 12, will serve as the definitive test.

Gamesa’s Make-or-Break Moment

Management has explicitly tied the confirmation of its full-year guidance to Gamesa reaching an operational breakeven. The wind division’s loss has narrowed sharply, from €374 million to €46 million, but that improvement was flattered by one-off effects. The first half of the fiscal year is still expected to show red ink; a meaningful recovery in the offshore segment is supposed to deliver the turnaround in the second half. If Gamesa misses that target, the consequences could be severe — regardless of how strongly the grid and gas turbine businesses perform.

The stakes are amplified by growing activist pressure. Hedge fund Ananym Capital has built a stake in Siemens Energy and is pushing for a spin-off of the wind unit, arguing that Gamesa is dragging down the valuation of the company’s thriving core operations. Chief Executive Christian Bruch has firmly rejected that proposal, insisting the group’s strategy is to fix Gamesa from within. But if the May 12 report shows the turnaround stalling, Ananym’s call for a breakup will gain considerable weight — and could overshadow the company’s planned share buyback program of up to €6 billion through 2028.

Analysts Split as Stock Sits Below Recent Highs

The analyst community is deeply divided on Siemens Energy’s prospects. JPMorgan has raised its price target to €200 with a buy rating, while Bank of America sees fair value at €230 and Morgan Stanley at €209. Goldman Sachs is more cautious at €185. At the other end of the spectrum, the lowest price target on the street stands at just €89 — a reflection of the valuation debate surrounding a stock trading at a forward price-to-earnings ratio above 50.

The shares closed Friday at €178.10, down 0.28 percent on the day. That leaves the stock roughly 45 percent above its level at the start of the year, but still about 5 percent below the 52-week high of €188 set in late April. The stock remains well above its 200-day moving average, signaling that the broader uptrend is intact.

Negative Power Prices: An Unexpected Tailwind

One of the more paradoxical drivers of Siemens Energy’s recent success is the growing volatility in European electricity markets. In the first quarter of 2026, the number of hours with negative power prices in the EU doubled to 1,223, compared with 593 in the same period last year. Spain, Portugal and Greece saw massive surpluses from renewable generation, while Germany experienced similar dislocations in April due to forecasting errors in feed-in volumes.

This volatility makes flexible, dispatchable capacity more valuable. Siemens Energy benefits on two fronts: as a manufacturer of gas turbines that can ramp up quickly to fill gaps, and as a supplier of grid technology that helps balance supply and demand. The structural demand from AI data centers only amplifies this dynamic.

Geopolitical Risk Lurks in the Background

Not everything is rosy. Around 35 percent of Siemens Energy’s gas turbine order volume is tied to the Middle East region, introducing a geopolitical risk factor that could weigh on the stock if tensions escalate. For now, the market is focused on the May 12 report. If Gamesa delivers, the narrative shifts back to the record order book, the margin expansion, and the buyback program. If it stumbles, the activist push for a breakup will become much harder to ignore — and the €6 billion buyback promise will fade into the background.
