Siemens Energy Closes the Siemens Chapter as Buyback and Wind Bottleneck Define the Next Test

Siemens Energy replaces departing board member Rebellius with ex-Nokia CEO Lundmark and launches a EUR 2 billion buyback as wind unit delays persist.

Siemens Energy has quietly severed the last personnel thread tying it to its former parent. Matthias Rebellius will step down from the supervisory board on 30 September 2026, ending a tenure that began in 2020 and overlapped with his departure from the managing board of Siemens AG. Because the former parent's stake has now slipped below five percent, Siemens AG no longer holds any contractual right to a board seat.

Acting on a request from the executive board, the Munich district court appointed Pekka Lundmark as his replacement effective 1 October 2026. Joe Kaeser stays on as supervisory board chairman. Shareholders will get their formal vote on the appointment at the annual general meeting on 25 February 2027.

Lundmark ran Nokia as chief executive from 2020 to 2025, giving him a background in global technology and infrastructure markets that maps onto the grid stabilization and network expansion work now central to Siemens Energy's agenda. His arrival signals a shift away from the administrative unwinding of the spin-off and toward a standalone identity built around connected power and data infrastructure.

A two-billion-euro signal to the market

The boardroom change landed alongside a far louder message. Siemens Energy launched the third tranche of its share buyback program, with plans to repurchase up to EUR 2 billion of its own stock by the end of March 2027, capped at 50 million shares. Some of the stock will feed employee programs; the remainder could be retired.

The equity traded at EUR 143.88 on the day, a modest gain of 0.3 percent. Since the start of the year the shares have added 20 percent, a run that already prices in much of the company's restored footing. A buyback of this scale reads as an unambiguous statement: the existential restructuring phase is considered finished internally, and liquidity now stretches to nine-figure returns of capital.

The bottleneck is not in the order book

For all the financial confidence on display, the operational reality is more sober. Marc Becker, who heads the offshore wind unit at subsidiary Siemens Gamesa, flagged a serious investment gap in European wind. Offshore projects totaling 48 gigawatts of awarded capacity across Europe are still waiting on final investment decisions. In Germany alone, permits for 16 gigawatts sit idle.

That delay cuts twice for Siemens Energy. Until utilities sign off on final financing, reserved manufacturing capacity cannot be converted into profitable deliveries. The company's traditional grid infrastructure and gas turbine businesses continue to benefit from global demand, but renewable execution is stuck between political intent and actual construction starts.

What the bulls are counting on

Optimists point to electrification trends they see as irreversible. Beyond his network and B2B technology work at Nokia, Lundmark brings strategic depth that fits the challenges of stabilizing and expanding grids worldwide. The full retreat of the former parent also frees the company from historical constraints — Siemens Energy can now pursue acquisitions, partnerships and capital measures without deferring to its old owner.

Should European governments speed up permitting and improve financing conditions, the pent-up project pipeline could unlock quickly. A green light for the blocked 48 gigawatts in Europe would hand Siemens Gamesa, as one of the leading equipment suppliers, years of high-volume orders. Combined with stable margins in the grid business, that would create substantial leverage for future profitability.

Idle capacity and the gap to the record high

The risks are just as concrete. If final investment decisions stall for an extended period, production sites face costly underutilization — offshore manufacturing cannot adjust lead times and capacity at short notice without generating significant fixed costs. Persistent cost pressure and uncertain interest rates add to the strain. If utilities have to renegotiate their calculations because of high financing costs, margins at equipment makers come under renewed pressure.

The chart reflects that drag. At EUR 143.80, the stock sits roughly 26 percent below its 52-week high of EUR 195.38, reached in April 2026. Unless management fully restores confidence in the long-term profitability of the wind unit, a valuation discount to peers is likely to persist.

The signals to watch

The setup now hinges on a clear sequence of markers. As long as demand in grids and gas turbine technology underpins earnings power, Siemens Energy has a solid base. But if the offshore business tips back into a renewed phase of strain through further delays on the European 48-gigawatt projects, analyst confidence could fray quickly.

The next concrete milestone arrives with the turn of the month, when Lundmark formally takes his supervisory board seat on 1 October 2026. Between now and the shareholder vote on 25 February 2027, the market will scrutinize every political step on European offshore tenders.
