Siemens Energy: Buyback Tally Grows as Naftogaz Talks and Fusion Bet Add New Subplots

Siemens Energy buyback hits 2,122,004 shares; DZ Bank lifts fair value to EUR 157 with Hold. Q4 results and 2026/27 outlook due November 11.

Siemens Energy has been busy on several fronts at once, and investors now face a familiar task: separating what has actually happened from what might. A mandatory disclosure published yesterday confirmed fresh purchases under the company's ongoing share buyback, while a pair of recent announcements — one in Ukraine, one in fusion technology — sketch out possible future business without yet delivering signed orders.

The buyback is no longer a promise

Last week alone, Siemens Energy picked up 936,589 of its own shares. Since the program launched on September 24, cumulative purchases had reached 2,122,004 shares as of last Sunday. Those filings document execution, not intention — but they say nothing about operating performance or the shape of any upcoming guidance. For anyone valuing the stock, capital measures and business expectations have to be weighed on separate scales.

DZ Bank lifts its fair value, keeps its distance

On Thursday, DZ Bank analyst Alexander Hauenstein raised his fair value for Siemens Energy from EUR 128 to EUR 157 while reaffirming a "Hold" rating. The sharply higher price target, in other words, did not come with a buy recommendation.

Hauenstein's reasoning points toward the upcoming earnings release. He anticipates a slight beat of the 2025/26 annual forecast and rising medium-term targets, while expecting the 2026/27 outlook to land roughly in line with consensus. That distinction matters: for the fiscal year just ended, the analyst sees room above company guidance; for the new year's outlook, he assumes no positive surprise relative to average market expectations. These are his projections — not reported results, and not a confirmed company forecast.

November 11 is the next test

Siemens Energy will publish fourth-quarter and full-year 2025/26 results on November 11, 2026, alongside its outlook for 2026/27. That date bundles together precisely the questions Hauenstein's valuation hinges on.

Separately, a possible sale of the "Transformation of Industry" division remains in play. Bloomberg reported financing packages of up to EUR 7 billion for potential buyers in connection with the topic covered roughly a week ago. CVC, EQT and Bain Capital were said to be examining bids; no completed sale has been announced.

Naftogaz: a memorandum, not a purchase order

On the deal front, Naftogaz and Siemens Energy signed a memorandum of understanding on October 5 covering energy security, protection of critical infrastructure and the modernization of underground gas storage, plus possible power generation projects. That scope reaches beyond any single procurement decision.

According to Reuters, Naftogaz is weighing the purchase of five gas turbine compressor units — a consideration that makes a potential commercial angle tangible, though it does not amount to a binding order. The distinction is decisive for how the news should be read. The memorandum describes fields of possible cooperation, not secured revenue. Investors should treat neither the mooted generation projects nor the contemplated procurement as closed business. The announcement opens perspectives; it does not yet evidence commercial execution.

A stake in fusion development

A second engagement concerns fusion technology. Type One Energy closed a Series B financing round of USD 200 million on October 6, with Siemens Energy Ventures participating alongside other investors. Type One Energy intends to use the proceeds for its fusion technology and Project Infinity.

For Siemens Energy, this is a stake in a development financing round. The figure cited is the total volume of the round, not Siemens Energy Ventures' contribution. The two announcements therefore differ in their economic message: Naftogaz concerns possible future procurement and joint projects, while the Type One Energy round is complete, with the funds earmarked for further technology development. Neither translates into revenue Siemens Energy has already booked.

What is proven, what is still expected

The documented progress sits with the buyback. Higher business targets and a possible divestment remain on the expectations side of the ledger. The November 11 release will show how much of that Siemens Energy can back up with its own numbers and a fresh outlook — and at Naftogaz, the decisive next step remains implementation of the contemplated procurement.
