Siemens Energy's Activist Heat and Wind Unit Recovery Collide Ahead of Q2 Report

Siemens Energy shares hover near record highs, but all eyes are on May 12 Q2 results as wind division Gamesa narrows losses, activist pushes breakup, and €6B buyback supports stock.

The stock has nearly doubled over the past twelve months and sits just a whisker below its all-time high of €170.86, yet the real tension at Siemens Energy is not about the share price — it’s about whether the wind division can finally deliver on its promises. With an activist investor pushing for a breakup and a €6 billion buyback programme running in the background, the stakes could hardly be higher for the May 12 second-quarter report.

Gamesa’s Loss Narrows, But the Clock Is Ticking

Siemens Gamesa remains the single biggest swing factor for the entire group. The wind turbine unit’s operating loss shrank to €46 million in the most recent quarter, a sharp improvement from the €374 million loss recorded in the same period a year earlier. That progress, however, still leaves the division far from the breakeven target CEO Christian Bruch has set for the full 2026 financial year.

The company’s internal roadmap calls for a negative first half, followed by a profitable second half, with the crucial inflection point expected in H2. Bruch has also laid out a medium-term margin target of 3 to 5 percent by 2028, with double-digit returns as the longer-term ambition. The management has been explicit: if Gamesa misses its internal timeline, the full-year guidance will take a hit.

Activist Pressure Meets Institutional Resistance

Hedge fund Ananym Capital has turned up the heat, demanding a full separation of the Gamesa business. The fund argues that a spin-off would unlock hidden value, allowing the profitable conventional energy operations to be valued on their own merits. Ananym estimates that Gamesa as a standalone entity could be worth around €10 billion within two years.

But not everyone is convinced. Major institutional shareholders including DWS, Deka Investment and Union Investment have pushed back against an immediate split, according to Reuters, preferring to give the current stabilisation plan more time to work.

Core Business Fires on All Cylinders

While the wind saga plays out, the rest of Siemens Energy is humming. Grid Technologies and Gas Services continue to deliver reliable growth, with the group already beating its own margin targets for those divisions. First-quarter revenue climbed nearly 13 percent to more than €9.6 billion.

The gas turbine business is booked solid through fiscal 2028, and orders for 2029 are filling up fast. The main bottleneck is the supply chain for blades and guide vanes — a sector-wide constraint rather than a company-specific problem. For 2026, the group plans capital expenditure of around €2.5 billion, with revenue growth forecast between 11 and 13 percent and an adjusted operating margin of 9 to 11 percent.

Tariff-related costs for the current year are estimated in the low triple-digit millions, a manageable figure given that 28 production sites in the US limit the company’s exposure to import duties.

Buyback Programme Gathers Pace

The share repurchase plan is providing structural support for the stock. Between April 13 and 19 alone, Siemens Energy bought back just over one million shares. Since the programme launched on March 4, the total repurchased stands at roughly 9.5 million shares. The first tranche is authorised for up to €2 billion, with a longer-term plan targeting buybacks of up to €6 billion by the end of 2028.

The stock changed hands at €169.16 recently, less than one percent below its record high from April 14. It has gained roughly 38 percent since the start of the year and more than 160 percent over the past twelve months. Analysts polled by FactSet expect a dividend of €1.70 per share for the current year, more than double the €0.70 paid last year.

What the May 12 Report Will Reveal

The upcoming second-quarter numbers will put Gamesa’s recovery trajectory under the microscope. Two metrics will dominate the conversation: the margin development at the wind unit and the free cash flow. If the breakeven curve holds, the activist pressure from Ananym may ease for now. If Gamesa misses its internal targets, the spin-off debate will intensify sharply.

For a stock trading near all-time highs with little valuation cushion, the room for disappointment is narrow.
