Siemens Energy’s Rally Hits a Pause Button as Grid Boom Clashes With Wind Woes

After a blistering 92 percent run over the past twelve months, Siemens Energy has hit a speed bump. The shares closed at €162.60 on Friday, down 2.73 percent on the day and 6.40 percent lower on the week. The pullback comes despite the completion of a €3bn share buyback and a flurry of strong operational data, a classic case of “buy the rumour, sell the fact.”

Investors are wrestling with two conflicting narratives. On one side, the grid-technology business is firing on all cylinders, with order books so full that the second half of fiscal 2026 is already 93 percent booked and 2027 is nearly 80 percent covered. On the other, the wind-turbine division Siemens Gamesa remains a persistent drag, and the market is growing impatient for proof that the turnaround is real.

A Buyback Done, a Partnership Locked In

Siemens Energy repurchased 12.6 million of its own shares between 4 March and 19 May 2026 at an average price of €158.50, representing roughly 1.47 percent of the share capital. The programme was ramped up from an originally planned €2bn to €3bn. Alongside the buyback, the group extended a long-term partnership with supplier Asta Energy through to 2032, with Asta investing in capacity expansions in India, China and Bosnia to secure supply chains.

The timing of the buyback’s finish, however, coincided with profit-taking. Since touching a high of €188.00 on 24 April, the stock has fallen 13.51 percent. The relative strength index of 53.1 suggests the market is cooling off rather than overheating — more a pause than a reversal.

Grid Goes Supersonic

The grid business is the clear engine of growth. Siemens Energy posted a record order backlog of roughly €154bn. Second-quarter order intake came in at €17.7bn, well ahead of the consensus estimate of €15.6bn. The US market is a standout: orders nearly doubled year-on-year to €6.94bn in the second quarter, while revenue there jumped 45.7 percent to €2.75bn.

The company plans to invest around €2bn by 2028 in a global network of transformer and switchgear plants, betting that capacity constraints in the electrical-equipment market will only tighten as grids are modernised to accommodate renewable energy. Grid Technologies is targeting an operating margin of 18 to 20 percent.

Should investors sell immediately? Or is it worth buying Siemens Energy?

Management’s full-year guidance calls for revenue growth of 14 to 16 percent and an operating profit of roughly €4bn. The free cash flow expectation was raised sharply to €8bn earlier this year.

Gamesa: The Final Piece of the Puzzle

Yet all this momentum hinges on one stubborn problem: Siemens Gamesa. Chief executive Christian Bruch has made it clear that the wind division must reach breakeven in the fourth quarter — not earlier — for the company’s annual forecast to remain intact. That is a significant nuance, because the market had hoped a third-quarter inflection was possible.

The cost of that uncertainty is visible in the cash flow statement, where free cash flow stood at minus €654m in the latest reported period. While the operating losses at Gamesa are shrinking, the unit has not yet turned the corner. “The wind business determines whether the guidance holds,” one analyst summarised.

Analysts Split on What Comes Next

The analyst community is deeply divided. JPMorgan rates the stock overweight with a €225 target, Berenberg is a buyer at €200, and Barclays sits at the opposite end with a €110 price target. Barclays analyst Vladimir Sergievskiy argued after the quarterly report that the current valuation already prices in an exceptionally favourable cycle.

That valuation debate is unlikely to be resolved soon. With volatility running near 50 percent, the shares can swing sharply on any news flow. The next major catalyst is the third-quarter earnings release on 5 August 2026. Before that, the European Central Bank’s rate decision on 11 June could provide a tailwind: lower capital costs tend to support the long-duration infrastructure contracts that underpin much of Siemens Energy’s order book.

For now, the company is between two forces. The grid division is delivering growth and visibility, but Gamesa remains a question mark. Investors who rode the 92 percent rally are taking some chips off the table, waiting for the answer to arrive this summer.
