Siemens Energy’s Record Run Faces a Make-or-Break Moment on May 12

Siemens Energy stock doubles to €188, but May 12 Q2 results will test wind unit Gamesa's turnaround and AI-driven grid growth amid analyst upgrades.

The stock has more than doubled since January, the market cap has swelled to €158 billion, and the company now ranks as Germany’s third-most-valuable listed business. Yet for all the euphoria surrounding Siemens Energy, the next big test arrives in less than two weeks.

On May 12, the group will publish its full second-quarter results. The preliminary numbers have already set a high bar: a cash flow forecast of roughly €8 billion for the full year—nearly double the original target—and a wind division that narrowed its operating loss more sharply than analysts expected. The question is whether Siemens Gamesa can sustain that improvement and whether the broader growth story holds up under scrutiny.

Deutsche Bank Pushes the Bull Case Further

The latest analyst upgrade came from Deutsche Bank Research, which lifted its price target from €180 to €195 while maintaining a buy rating. The bank cited sustained demand in grid infrastructure and improving profitability prospects as the key drivers.

That puts Deutsche Bank at the top end of the analyst spectrum. Goldman Sachs also recommends buying the stock, though with a more conservative target of €185. At the other extreme, Barclays remains the standout skeptic with an “Equal Weight” rating and a €100 target—a gap of roughly €88 from the current share price of €188.

GE Vernova’s Numbers Validate the Thesis

The rally has been reinforced by results from US competitor GE Vernova, which reported first-quarter free cash flow of $4.8 billion—more than it generated in the entire 2025 fiscal year. The company also raised its 2026 revenue guidance to between $44.5 billion and $45.5 billion.

For Siemens Energy, the message is clear: the global push to modernize power grids is no short-term phenomenon. Both companies are riding a structural wave of rising investment in energy infrastructure, a trend turbocharged by the AI boom.

AI’s Insatiable Appetite for Power

The energy demands of data centers have become the central growth engine for Siemens Energy’s Grid Technologies division. OpenAI alone is reportedly planning to build up to 30 gigawatts of capacity by 2030. Transformers and complex grid connections—core products of this division—are in short supply and high demand.

Grid Technologies is expected to deliver 25 to 27 percent revenue growth this fiscal year, with an operating margin of 18 to 20 percent. The stock currently trades about 18 percent above its 50-day moving average, with a relative strength index of 61—technically elevated but not yet in overbought territory.

Gamesa: The Lingering Risk

The entire growth narrative, however, hinges on one unresolved weak spot: Siemens Gamesa. The wind unit posted an operating loss of €44 million in the second quarter, a sharp improvement from the €249 million loss a year earlier and better than the €74 million loss analysts had expected. Management remains committed to reaching break-even by the end of fiscal 2026.

That hasn’t silenced the critics. Activist investor Ananym Capital is pushing for a full spin-off of Gamesa, arguing that the profitable core businesses would unlock their true value without the drag. Major institutional shareholders such as DWS and Union Investment have so far backed management’s strategy.

Buybacks and Tariff Risks

The company is actively buying back its own shares. The program, which started on March 4 and runs through September, covers up to €2 billion. In the week of April 13 to 19 alone, Siemens Energy purchased just over one million shares. Since the program began, nearly 9.5 million shares have been repurchased. This is the first tranche of a larger plan that aims to return up to €6 billion to shareholders by the end of 2028.

Potential headwinds from US import tariffs appear manageable. With 28 production sites in the United States, Siemens Energy can absorb most of the impact. Management expects tariff-related additional costs in the low triple-digit million-euro range for 2026.

What the May Report Must Deliver

When the full quarterly report lands on May 12, it needs to confirm the preliminary figures across all segments. The cash flow forecast of around €8 billion must hold, and Gamesa must show it can keep pace rather than become a brake on the entire outlook. The resistance zone between €191 and €195 will be the next technical test—and the next chapter in a story that has already made Siemens Energy one of the most remarkable performers in the DAX.
