Siemens Energy: Fusion Heat-to-Power Talks, a 40% Earnings Gap to GE Vernova, and the Buyback Running Alongside Both
Published on 10/27/2026 at 10:31 | Editorial boerse-global.de
Siemens Energy is pursuing two very different growth stories at once — one measured in decades, the other in quarterly consensus figures. On the long horizon sits a planned fusion collaboration with Japan's Kyoto Fusioneering and Mitsui, aimed at developing technology that converts heat from fusion reactors into electricity efficiently. Media reports suggest the arrangement is to be agreed during the German Chancellor's visit to Japan. That makes it a development project, not a signed contract, and certainly not a supply order.
Investors should treat the fusion angle as a technological option rather than a secured contribution to earnings. The wording matters: the cooperation "is to be agreed," which is a statement of intent, not a completed deal. The stock added 1.5% on the day, though that move alone cannot be read as a clean reaction to the fusion report — the near-term share price and the long-term technology story deserve to be weighed separately.
Bruch's Near-Term Case: Gas, Renewables, Reform
Set against the fusion plans are CEO Christian Bruch's comments on energy supply, published yesterday. Bruch called for reforms, an expansion of renewables and fast-to-deploy gas-fired power plants. He also noted that Siemens Energy invested more than EUR 1 billion in German sites between 2022 and 2025.
The two themes sit at opposite ends of the timeline. The Kyoto Fusioneering and Mitsui project concerns technology development; Bruch's demands concern policy reform and building out supply capacity now. Neither substitutes for the other.
Should investors sell immediately? Or is it worth buying Siemens Energy?
The Valuation Gap That Anchors the Bull Case
Where the second thread of the story begins is valuation. The Wall Street Journal describes Siemens Energy as a potentially overlooked play in the artificial-intelligence buildout, trading roughly 40% below GE Vernova on expected earnings. The comparison holds up because the two businesses are close cousins: both sell electrification equipment in heavy demand, both post broadly similar revenue, and both carry wind divisions with troubled histories.
Scale backs the pairing. According to BloombergNEF, Siemens Energy and GE Vernova have been the world's two largest gas turbine manufacturers by confirmed orders since 2016, with each booking orders of around 150 GW through the first half of 2026. That order book argues against judging Siemens Energy solely on the struggles of its wind business — but a cheaper multiple than a rival does not, on its own, answer how much profit and cash flow the company converts from that demand.
A Cash Flow Model That Pushes Back
A discounted cash flow valuation published today lands well below the market price, assuming cash flows decline in the years ahead. The tension with the relative-valuation argument comes down to different yardsticks: the peer comparison looks at expected earnings, while the model looks at the long-run trajectory of cash generation.
The raw inputs are strong. Media reports put free cash flow at roughly EUR 7.8 billion over the past twelve months, alongside a record order backlog of EUR 162 billion. Even so, a discount to GE Vernova can flag an opportunity without settling whether recent cash generation is durable. That question is what separates the two camps.
November 11 Is the Next Real Test
The next hard data point is scheduled for November 11, when Siemens Energy is expected to report quarterly figures. Consensus puts earnings per share at EUR 1.33, against EUR 0.190 in the prior-year quarter, on revenue of EUR 12.72 billion — growth of 21.99% from EUR 10.43 billion a year earlier.
Siemens Energy at a turning point? This analysis reveals what investors need to know now.
That is a high bar, and the expected improvement is already baked into the investment case rather than reported. Meeting it would go some way toward validating the earnings-based valuation; the more cautious cash flow model, meanwhile, warns against extrapolating a strong quarter indefinitely.
Buyback Ledger Keeps Ticking
Running in the background is the share repurchase programme. Siemens Energy bought back 1,294,334 of its own shares last week, taking the total since the programme began on September 24 to 4,513,232 shares by the end of last week. Unlike the fusion cooperation, which is still to be agreed, the buyback is already in motion — a distinction that matters more to investors than any rushed financial verdict on the development project.
