Siemens Energy Charts Solo Course as Omterra Split and Board Overhaul Redraw the Map
Published on 09/26/2026 at 21:10 | Editorial boerse-global.de
Siemens Energy is entering the final stretch of its divorce from Siemens AG, and the terms of the separation are now coming into focus. With the Munich parent's stake having slipped below the 5% threshold, the energy technology group has lost its contractual right to a supervisory board seat — a shift that triggered a reshuffle of the control panel on Thursday.
Matthias Rebellius will step down from the board on September 30 at his own request. Pekka Lundmark, the former Nokia chief executive, is set to take his place effective October 1, with a formal election slated for the annual shareholder meeting on February 25, 2027. For the company, the change amounts to greater latitude on strategic decisions — and it severs the last of the close personnel ties to the former parent.
A New Name and a Leaner Portfolio
Management reportedly intends to rebrand as Omterra from the end of 2026. Dropping the legacy name would eliminate annual licensing fees of roughly EUR 300 million, further unwinding the remaining links from the spin-off.
The corporate overhaul extends well beyond branding. About a month ago, the supervisory board approved the carve-out of the Transformation of Industry division, which generates around EUR 5.7 billion in revenue and employs 17,000 people. The plan calls for deconsolidation through external investors or a capital markets transaction, with Siemens Energy retaining a substantial minority stake. The segment posted an 11.3% margin in fiscal 2025 and is viewed as highly profitable, so a partial sale or eventual IPO could unlock considerable value.
Market observers read the portfolio cleanup as a necessary move to safeguard profitability and steer resources toward higher-growth areas. At the same time, the remaining group forfeits a dependable earnings engine that has historically offset its more volatile operations.
Should investors sell immediately? Or is it worth buying Siemens Energy?
Nuclear Order Book Gets a Boost
On the operational front, a consortium of Aecon and Siemens Energy Canada landed a major contract in Canada on Monday. The Pickering nuclear plant modernization in Ontario carries a total volume of CAD 1.3 billion, equivalent to about EUR 800 million. Siemens Energy's share covers generator overhauls, the delivery of 14 steam turbine rotors and modern control technology — a reminder of the group's entrenched position in conventional power and plant engineering, which continues to throw off reliable revenue.
Offshore wind is contributing its own momentum. The Borkum Riffgrund 3 wind farm in the North Sea entered full commercial operation at the end of August, featuring 83 SG 11.0-200 DD turbines from Siemens Gamesa and a combined capacity of 913 megawatts.
The Wind Unit's Make-or-Break Year
The central question for the capital market is whether the recovery in wind power will hold. The rehabilitation of Siemens Gamesa sat at the heart of the group's crisis for years, as quality defects and project delays racked up billions in losses. The wind division reported a positive quarterly result more than a month ago for the first time since fiscal 2022, yet the full-year test still lies ahead. Reaching break-even for the entire fiscal 2026 remains management's stated goal, and clearing that hurdle would remove the group's single largest uncertainty.
A record order backlog of EUR 162 billion, booked as of June 30, provides ballast. The key for investors is that these orders are executed at solid margins and without costly rework. Third-quarter revenue climbed 17.47% to EUR 11.45 billion, with earnings per share of EUR 1.28 — evidence that demand for grid technology and conventional power infrastructure remains robust.
Risks Lurk in Long-Dated Projects
Serious risks persist, chiefly in the long timelines of complex infrastructure work. Major contracts for offshore grid connections, including high-voltage components, can run until the end of 2034. Supply bottlenecks, inflation or technical complications can generate substantial extra costs over such extended horizons.
The stock has also priced in plenty of good news. Siemens Energy shares have gained 20% since the start of the year and closed Friday at EUR 144.06. Setbacks on large projects or manufacturing delays could quickly translate into tangible disappointment. Analyst consensus points to an average price target of EUR 194.80, according to media reports on Wednesday.
A Clear Fork in the Road
For investors, the situation boils down to a straightforward decision point. As long as Siemens Energy stays on track toward its targeted break-even in wind for fiscal 2026, the case for a re-rating holds. Should the division unexpectedly slip back into the red in the final quarter, market confidence would likely take a heavy hit. Until the coming annual results clarify how sturdy the operating foundation really is, the newly won independence and sharpened portfolio at least give the company clear contours for its next chapter.
