Siemens Energy: The AI Infrastructure Play That’s Also a Breakup Story

Siemens Energy stock gains 78% in 12 months as record backlog from grid decarbonization and AI demand fuels growth; planned spin-off of industrial division may unlock value, while wind unit Gamesa nears break-even.

For a company that two years ago was synonymous with writedowns and a listing wind-turbine business, Siemens Energy has done more than recover — it has repositioned itself at the sharp end of two megatrends at once. The decarbonisation of power grids and the ballooning electricity needs of artificial intelligence are feeding a record order backlog that now gives the DAX-listed group years of visibility. That fundamental shift, rather than a single news item, explains why the stock has added roughly 78 percent over the past twelve months and is up 33.44 percent since January.

Yet the recent run has not been smooth. After hitting an April high of €195.54, the shares pulled back more than 16 percent, and the last 30 days have seen a 10 percent decline. Thursday’s 3.38 percent gain to €163.86 snapped a soft patch and rekindled attention on a strategic move that could unlock further value: the planned spin-off of the “Transformation of Industry” division, which houses compressors, steam turbines and conventional industrial equipment.

The market’s immediate reaction — an advance that put Siemens Energy at the top of the DAX leaderboard — reflects a belief that the conglomerate discount that has long dogged the stock may finally be closing. Analysts at JPMorgan, Jefferies and Deutsche Bank have all struck a positive tone, arguing that a tighter focus on grid technology and gas-turbine services would give investors the “pure play” exposure they have been asking for. The spin-off, still under review, is a clear signal that management intends to concentrate capital where demand is hottest: the infrastructure that underpins both the energy transition and the data-centre boom.

A growing slice of new orders now comes directly from projects tied to digital infrastructure expansion, particularly in the United States. Gas turbines — used as backup for intermittent renewables and as stabilisers for power-hungry AI clusters — are driving a cycle that extends well beyond traditional energy policy. At the same time, a small but symbolic partnership with the start-up Ucaneo on direct air capture technology shows the company is also planting flags in the longer-term carbon-removal market, even if the near-term balance-sheet impact is negligible.

The stubborn problem child remains Siemens Gamesa, the wind-turbine subsidiary that has bled billions and damaged credibility. Activist investors have pushed for a full separation, but the company has so far resisted. Yet there are growing signs that the offshore wind division is approaching break-even. If Gamesa stabilises, the risk discount that has dragged on the entire group valuation could begin to lift. That would allow the core grid and gas businesses to command the multiple they arguably deserve.

None of this removes the headline risks. Geopolitical uncertainty and policy shifts remain real, and a 55 percent annualised volatility figure reminds holders that this is not a stock for quiet nights. The 50-day moving average sits at €168.89, still above the current price, while the 200-day average at €139.67 confirms the long-term uptrend is intact. Whether the shares can retest the April peak depends on how cleanly the spin-off proceeds and whether the wind division can deliver on its turnaround promise.

For now, the narrative has changed. Siemens Energy is no longer a turnaround story — it is an infrastructure enabler riding the convergence of electrification and artificial intelligence. The next chapter will be written when the spin-off plan takes concrete shape and Gamesa proves it can finally stop being the hole in the hull.
