Siemens Energy Courts Data Center Boom at Cannes as Buyback and Backlog Bolster Recovery

Siemens Energy pitches scalable power systems at Datacloud Congress, reports record backlog and €3.6B shareholder returns, stock bounces from 10% dip.

Siemens Energy is taking its data center pitch to the French Riviera this week, marking a strategic push into one of the fastest-growing demand drivers for grid and gas turbine technology. The Munich-based group is the patron sponsor of the Datacloud Global Congress 2026 in Cannes, a three-day event running from 2 to 4 June that draws more than 6,000 industry executives, roughly 70% of them at C-level, VP or director level. Under the slogan “Let’s energize data centers,” the company is showcasing its ability to deliver scalable power systems at a time when the AI boom and hyperscaler expansion are driving a structural surge in electricity consumption.

The congress appearance comes as Siemens Energy’s stock tries to shake off a recent pullback. After three consecutive losing days that wiped roughly 10% from the share price — from just above €174 to below €164 — the equity rebounded on Monday, gaining 1.81% to close at €165.54. That leaves it just shy of its 50-day moving average of €167.65 but comfortably above the 200-day line of €133.82. No fresh corporate announcement accompanied the bounce; a vague analyst comment, cited in a market report, may have helped sentiment, but the move looks primarily technical in nature.

The underlying operational story, however, remains robust. In the second quarter of fiscal 2026, Siemens Energy posted order intake of €17.7 billion, a book-to-bill ratio of 1.72, and a record order backlog of €154 billion. Adjusted earnings before special items rose to €1.164 billion from €906 million a year earlier, while net profit climbed to €835 million. The Grid Technologies division, which lifted its full-year revenue growth forecast to 25-27% with an operating margin target of 18-20%, was the standout performer. Gas Services also contributed strongly, and the group now expects comparable revenue growth of 14-16% for the full year, an adjusted margin of 10-12%, net profit of around €4 billion, and free cash flow before taxes of roughly €8 billion.

Adding to the positive cash story, Siemens Energy has accelerated its share buyback programme. The first tranche, which ran from 4 March to 19 May, saw the company repurchase exactly 12.6 million shares — 1.465% of issued capital — at an average price of €158.50. Originally set at €2 billion, the programme was upsized by up to €1 billion thanks to strong cash generation, bringing total shareholder distributions for the current fiscal year to €3.6 billion. Looking further ahead, Siemens Energy plans to return around €10 billion to shareholders by 2028, with €6 billion earmarked for buybacks.

The stock still has ground to recover. Despite a year-to-date gain of nearly 35%, it trades about 12% below its April 52-week high of €188. The next major catalyst is the third-quarter earnings report on 5 August, when the market will assess whether Grid Technologies and Gas Services can sustain their record pace of order conversion. With a backlog of €154 billion and a high-profile marketing push in Cannes, the company is positioning itself as the go-to energy partner for the data center revolution — but the autumn numbers will need to deliver the hard results to back up the narrative.
