Siemens Energy's Data Center Bonanza Yields 5GW of Orders, but €1bn Buyback Must Battle Profit-Takers

Siemens Energy shares slide 15% in a month as profit-taking hits, but record orders from data centres and a €1bn buyback back the long-term uptrend.

Investors have been taking money off the table at Siemens Energy, handing the stock its deepest monthly slide in more than a year even as the company launches a €1bn share repurchase and flags an explosion of demand from hyperscale data centres. The shares slipped to €157.92 on Friday, down 0.88%, bringing the 30-day decline to 14.96%. The sell-off comes despite a year-to-date gain of 28.60% and a 12-month advance of 79.05%, a rally that market participants attribute to routine profit-taking after such a powerful run.

The pullback has dragged the relative strength index to 39.7 — a reading that signals cooling but not panic. Crucially, the long-term uptrend remains intact, with the stock trading above its 200-day moving average even as it has dipped below the shorter-term averages.

Data centres provide the spark

While the share price has faltered, the underlying business is humming. Siemens Energy used the Datacloud Global Congress in Cannes this week to position itself as the go?to partner for the world's largest cloud operators — Amazon Web Services, Microsoft and Google — all scrambling to secure enough power for their artificial?intelligence workloads.

The numbers are striking. A quarter of all orders in the Gas Services division now come from data?centre projects. In the fiscal second quarter alone, Siemens Energy locked in contracts representing 5 gigawatts of capacity. The technology group's Grid Technologies unit, which integrates battery storage through its Fluence joint venture and supplies transformers, is providing the hardware needed to stabilise intermittent renewable power for AI server farms.

Goldman Sachs has taken notice, adding Siemens Energy to its "European Conviction List" and calling the company a "structural winner" from both the energy transition and the AI boom. The bank's analysts expect the operating result in 2030 to come in roughly 10% above the current market consensus.

€1bn buyback: not a magic bullet

The new €1bn share repurchase tranche that began on 4 June will run at most until 30 September. It is the second instalment of a programme that could see Siemens Energy buy back up to €6bn of its own stock by the end of fiscal 2028. The shares will be used either for employee compensation and staff programmes or for cancellation.

But the buyback is no simple lever to pull. A mandated bank decides the timing of purchases, and Siemens Energy can only intervene by suspending or restarting the mandate within legal limits. The purchase price cannot exceed the Xetra opening price by more than 10%, nor fall below it by more than 20%. Daily volumes are capped at 25% of the average traded turnover over the preceding 20 trading days. So while the programme will absorb some supply, it cannot substitute for broad market support.

Record backlog and strong guidance

The buyback is hardly happening in a vacuum. Siemens Energy posted order intake of €17.749bn in the fiscal second quarter, a book?to?bill ratio of 1.72 and a record backlog of €154bn. The operating result before special items jumped to €1.164bn and net income reached €835m, while pre?tax free cash flow hit €1.975bn.

Management expects comparable revenue growth of 14–16% for the current fiscal year, an operating margin before special items of 10–12%, net income of around €4bn and pre?tax free cash flow of roughly €8bn. Half of the backlog still needs to be converted into higher margins, and the wind turbine business Siemens Gamesa remains a turnaround case. Even so, the booming grid and gas turbine operations are driving profitability.

Roadshow to address the margin question

This week the management team is fanning out across European financial centres for a roadshow. The central question from investors: how quickly can the €154bn order book translate into fatter margins? The next quarterly results, due on 5 August, will provide the first real answer. Until then, the buyback reports — which Siemens Energy must disclose no later than seven trading days after execution — will offer the most visible gauge of whether management's firepower is enough to steady the stock.
