Siemens Energy: €3 Billion Buyback Surge Masks the Activist Pressure on Gamesa

Siemens Energy accelerates €3B buyback as activist presses for wind-turbine spin-off; strong grid and gas-turbine cash flows fund returns, but Gamesa turnaround is critical.

Siemens Energy has reignited its share buyback programme with a fresh €1 billion tranche, but the headline-grabbing capital returns mask an unresolved tension that could shape the company’s future. Activist investor Ananym is pushing for a spin-off of the wind-turbine arm Siemens Gamesa, and while large institutional holders such as DWS and Union Investment have so far backed management’s strategy, the margin for error is shrinking.

The first buyback leg, covering €2 billion worth of stock, was wrapped up in just 77 trading days — three months ahead of schedule. Between 4 March and 19 May, Siemens Energy purchased 12.6 million of its own shares at an average price of €158.50 apiece. That pace was fuelled by an operating cash flow that has far exceeded expectations. In the second quarter, free cash flow before taxes surged 42% to €1.98 billion, prompting the board to pull forward a future tranche and lift this year’s total buyback budget from €2 billion to €3 billion.

Adding in the dividend paid out in March, total shareholder distributions for the 2026 fiscal year are set to reach about €3.6 billion. The repurchased stock will either be funnelled into employee programmes or cancelled. Cancellation would provide a permanent boost to earnings per share, a move that tends to reward long-term holders. Looking further ahead, Siemens Energy has pledged to return €10 billion to shareholders by 2028, with €6 billion of that coming through buybacks.

The strong cash generation behind this largesse stems from a core business that is firing on all cylinders. Revenue in the second quarter climbed to €10.3 billion, and earnings per share rose to €0.89 from €0.50 a year earlier. Management has raised its full-year guidance for comparable sales growth to between 14% and 16%. The main drivers are power grids and gas turbines, capitalising on demand from the artificial-intelligence boom and a wave of energy-hungry data centres. The order backlog now stands at €154 billion, stretching well into the 2030s.

Yet the market’s favourite topic remains Gamesa, the wind division that has weighed on group profitability for years. Encouragingly, its quarterly loss narrowed to €46 million from €374 million in the same period last year. Restructuring is making headway, but it is not complete. Management has set a target of reaching breakeven this year, and the stock’s recent strength suggests investors are giving the company the benefit of the doubt. Should Gamesa miss that target, however, activist pressure for a separation will intensify. The risk profile is asymmetric: robust grid and service numbers can support the overall result, but they cannot offset fresh quality setbacks at the turbine business.

The strong narrative has not come cheap. Siemens Energy shares traded at €182.42, barely 3% below their 52-week high of €188. The stock has roughly doubled over the past twelve months and gained nearly 49% since the start of 2026. At these levels, the trailing price-to-earnings ratio of 67.4x sits far above the peer average of 38.4x and the European electrical-engineering sector multiple of 29.5x. For the rally to sustain, the company must convert its €154 billion order book into profitable revenue and, above all, demonstrate that Gamesa can stand on its own.

The next major checkpoint arrives on 5 August, when Siemens Energy publishes its third-quarter results. That day will show whether the cash-flow momentum continues and, more critically, whether Gamesa is on track to break even. For now, the buyback machine is running at full throttle, but the activist question remains open.
