Siemens Energy: Nuclear Training Triples as AI Funding Doubts Weigh on the Stock
Published on 10/24/2026 at 06:10 | Editorial boerse-global.de
Siemens Energy has more than tripled its training programmes for field service engineers and project managers, a build-out tied to the restart and modernisation of nuclear power plants. The move lands at an awkward moment for the share price, which closed yesterday at EUR 118.06, down 2.9% on the day. Investors now face a split-screen question: whether concrete power plant projects can offset worries about how the AI build-out gets financed.
A Staffing Signal, Not Yet an Order Book Entry
The expanded training effort, reported yesterday by Power Engineering, widens the personnel base for nuclear work. It does not by itself equal new orders or booked revenue, a distinction that matters more than usual after the recent selling. What counts for the investment case is not sentiment toward new data centres alone, but what the already-named energy projects can deliver.
Behind the training push sit specific upgrades. At Byron and Braidwood in Illinois, turbine and generator upgrades are meant to add hundreds of megawatts of capacity. Four units are being modernised at Pickering in Ontario. In Michigan, Palisades is set to return roughly 800 megawatts to the grid after about two years of work. Those are tangible projects rather than an abstract bet on rising electricity demand.
Siemens Energy is also working with Rolls-Royce on a small modular reactor and with Oklo on the Aurora microreactor. Both count as development partnerships, not realised additional earnings.
Should investors sell immediately? Or is it worth buying Siemens Energy?
The Funding Question Wall Street Is Circling
The pressure on the stock traces to a different debate. BofA strategist Sebastian Raedler sees growing reluctance to finance AI infrastructure, which feeds through to Siemens Energy via expectations for data-centre power demand. If such projects become harder to fund, the anticipated call on energy infrastructure could prove less reliable.
The warning signs are coming from the financing market itself. Firmus cancelled its planned IPO for lack of demand. CoreWeave bonds maturing in 2032 traded at yields of up to 15% at times. Raedler also flags rising financing costs and the risk of weakening pricing power as competition intensifies. None of this amounts to cancelled Siemens Energy orders, but it explains why doubts about the AI build-out reach beyond the technology sector.
A EUR 162 Billion Backstop
Set against those concerns is a substantial order book. Siemens Energy booked EUR 17.9 billion in orders in the third quarter of 2026, lifting its backlog to EUR 162 billion. That cushions the funding worries, though a large backlog documents orders already won rather than the pace of future intake — and that pace could come under closer scrutiny as investors assess the returns on big AI projects more critically.
The picture inside the business is uneven. At Gamesa, order intake in the same quarter came to about EUR 1.05 billion, down from EUR 4.89 billion a year earlier. Reading the company as a pure AI winner misses that split, just as equating a weak share price with an operational slump does.
Siemens Energy at a turning point? This analysis reveals what investors need to know now.
Two Analysts, Two Very Different Targets
Sell-side views diverge sharply. JPMorgan rates the stock "Overweight" with a price target of EUR 245, pointing to considerable expected upside without guaranteeing that execution follows. Barclays sits at the other end, with "Underweight" and a EUR 130 target. The gap between the two captures how differently the coming quarters are being read.
The November Catalyst
The next scheduled checkpoint is 11 November, when Siemens Energy reports its business figures alongside an outlook through 2027. That date could bring operating opportunities and financial expectations closer together. Until then, the case rests between two plausible outcomes: a broadening project base that justifies confidence, and persistent funding risks that overshadow it. The nuclear training news strengthens the operational side of that ledger. It does not settle the economic proof.
