Siemens Energy is buying €2 billion of its own stock as Siemens AG slips below 5%

Siemens Energy started buying its own stock on 24 September: up to €2 billion, capped at 50 million shares, the third tranche of a €6 billion program that can run to 31 March 2027 ¹. The stock funds employee share programs and share-based pay, or retires outright ¹⁹. Sixteen days earlier, on 8 September, Siemens AG's holding arm slipped to 4.98%, below the threshold that came with a supervisory board seat ². No filing shows the parent selling into the tranche. The record shows sequence: a seller stepping out as the company steps in as buyer.

The last board seat empties Wednesday

Matthias Rebellius leaves the supervisory board on 30 September at his own request; a Munich court has seated Pekka Lundmark, Nokia's chief executive from 2020 to 2025, from 1 October, with shareholders voting on 25 February 2027 ³. Ex-Siemens chief Joe Kaeser stays on as chair ³. The rebrand to Omterra, announced 14 July↗, retires the time-limited brand license signed at the 2020 spin-off ⁴⁶. The dividend from independence is literal: dropping the Siemens name stops roughly €300 million a year in fees to the parent ⁵⁶, about one full buyback tranche every seven years.

The orders are budget money and AI money

On 21 September, Ontario Power Generation split C$3 billion of Pickering refurbishment work; the Aecon-Siemens Energy consortium takes the C$1.3 billion turbine-generator slice, covering 14 new steam turbine rotors, overhauls of four generators with stator rewinds, and new control systems ⁷⁸. Execution begins January 2027, pending regulatory approval ⁷.

On 14 September, YTL Power and Ganda Power signed for four more SGT-9000HL gas turbines↗, taking the booked fleet to seven units and more than 5,250 MW ⁹¹¹. Nvidia-backed YTL plans to double its data-center capacity to 2.4 GW by 2030; its managing director calls energy "the foundation of the AI economy" ¹⁰¹¹.

€245 calls it structural, €100 calls it a cycle

Third-quarter orders hit a record €17.9 billion↗, the backlog €162 billion, book-to-bill 1.57; Siemens Gamesa posted its first positive quarter since fiscal 2022, €75 million of operating EBITA ¹². Nine of eleven tracked analysts say buy, targets €130 to €250 ¹². A 6.9% one-day drop on 14 September, after a GE Vernova downgrade and AI-capex doubt, showed how fast that belief reprices ¹¹.

Leon Mühlenbruch of mwb Research keeps a sell at €100 on a stock near 25 times 2027 earnings: "Even the strongest investment cycles eventually normalize" ¹³. Against the €144.06 close, €100 implies about 31% downside; the note itself claimed over 29% on its own price basis↗ ¹³⁸. Berenberg holds €205 and calls the company a structural beneficiary of government grid budgets ²; JPMorgan's €245 is the street's high ¹.

Wind break-even is a target, not a result

The pre-close call falls on 30 September↗, the day Rebellius walks out; full-year results follow on 11 November ⁸¹. Gamesa's operating break-even for fiscal 2026 is management's stated goal, not yet a result ¹²⁶.

The other leg thins at the same time: the Transformation of Industry carve-out, €5.7 billion of revenue at an 11.3% margin with 17,000 staff, hands away the division that steadied earnings against the volatile units ¹²⁶. The buyback retires shares at a price that assumes the cycle holds. The fourth quarter has to show the wind unit agrees.
