Siemens Energy said on 11 November that its order backlog reached a record €164 billion at the end of fiscal 2026, up 18.2% from €138 billion, according to its results release and earnings release. It plans to repurchase additionally up to €9 billion of its own shares through the end of fiscal 2030. That comes on top of the programme on its buyback page: up to €6 billion by the end of fiscal 2028.
By our arithmetic the backlog equals 3.7 years of the €44.2 billion of fiscal 2026 revenue. The gas turbine and service unit, Gas Services, holds €74 billion of it, or 5.1 years of its own €14.5 billion revenue, by the same arithmetic. A Wall St Engine post put the shares up 7% on the day; Yahoo Finance data for the Xetra listing showed €128.44 at 08:51 UTC against a €119.84 previous close, up 7.2% by our arithmetic.
Business Pill · Backlog
An evergreen Business Engineer explainer on backlog, revenue that is signed but not yet earned. It teaches the general idea only and does not discuss Siemens Energy.
The key insight: As we read it, Siemens Energy’s record €164 billion backlog leans on its gas unit: Gas Services holds €74 billion, or 5.1 years of its fiscal 2026 revenue by our arithmetic, and the company plans up to €9 billion more in buybacks through fiscal 2030 on top of a €6 billion programme.
The fiscal year ended on 30 September. The company says orders rose 18.8% on a comparable basis to €68.1 billion and revenue 15.5% to €44.2 billion, a book-to-bill ratio of 1.54. Profit before Special items more than doubled to €5,486 million from €2,355 million, a margin of 12.4% against 6.0% a year earlier.
Gas Services drove the order book. The release says its orders rose 45.9% to €32.8 billion, while Grid Technologies grew orders 14.5% to €24.0 billion. Orders in the United States rose 70.8% to €27.7 billion at group level, about 41% of the group total by our arithmetic.
Free cash flow pre tax nearly doubled to €8,799 million, and the release says customer advance payments, including reservation fees, also contributed. Net income was €4,129 million, against €1,685 million. Siemens Gamesa, the wind unit, reached break-even with Profit before Special items of €8 million, against negative €1.4 billion a year earlier.
The company proposes a dividend of €2.30 a share, against €0.70 for fiscal 2025, and says shareholder returns for fiscal 2026, including buybacks, total €5 billion. The earnings release puts the buyback during the year at €3.1 billion. The buyback page says the third tranche of the €6 billion programme, up to €2 billion, started on 24 September 2026.
Siemens Energy order backlog at 30 September 2026 against fiscal 2026 revenue, by segment, from the Earnings Release Q4 FY 2026 of 11 November 2026: Gas Services EUR74 billion vs EUR14.5 billion, Grid Technologies EUR52 billion vs EUR14.1 billion, Siemens Gamesa EUR31 billion vs EUR10.6 billion, Transformation of Industry EUR8 billion vs EUR5.8 billion. Years of revenue are our arithmetic.
What Was Posted on X
Siemens Energy +7% as power demand from AI data centers and broader electrification boosts orders for gas turbines and grid equipment.
It targets 12%-14% annual revenuegrowth through 2030 and 20%-22% profit margins, up from 12.4% in FY26.
It announced €9B more in buybacks.
Profit before special items more than doubled to €5.5B in FY26, while its order backlog reached a record €164B, up 18.2% YoY.
The new buyback comes on top of an existing €6B program.
CEO Christian Bruch pushed back on AI bubble concerns, noting that less than 10% of Siemens Energy’s backlog is tied to data centers, with demand extending well beyond the AI buildout.
Wall St Engine, a market news account, posted at 08:23 UTC on 11 November that Siemens Energy shares were up 7% and summarised the results: the 2030 targets, the extra EUR9 billion of buybacks on top of an existing EUR6 billion programme, and the record EUR164 billion backlog. It is the only source we have for its account of chief executive Christian Bruch saying that less than 10% of the backlog is tied to data centers; we did not find that figure in the company documents we read.
The 2027 and 2030 Targets
For fiscal 2027 the company says it expects comparable revenuegrowth of 14% to 16%, a Profit margin before Special items of 14% to 16%, net income of around €5 billion and free cash flow pre tax of around €10 billion. Reuters reported that a company-provided poll had put the 2027 margin at 14.7%.
For fiscal 2030 the release gives compound annual comparable revenuegrowth of 12% to 14% from fiscal 2026 and a Profit margin before Special items of 20% to 22%. The earnings release assumes Gas Services grows revenue 24% to 26% in fiscal 2027 at an 18% to 20% margin, and Grid Technologies 22% to 24% at 21% to 23%.
The outlook names data centres directly: “The build-out of data centers to support the adoption of artificial intelligence is likely to lead to further investment in power generation capacity and grid infrastructure, especially in North America.” Chief executive Christian Bruch said in the release: “We delivered on our commitments: We met all raised guidance targets, significantly increased earnings and achieved break-even in our wind business.”
Profit margin before Special items by segment, fiscal 2026 actual against the midpoint of the fiscal 2027 guidance range, from Siemens Energy’s Earnings Release Q4 FY 2026 of 11 November 2026. Midpoints are our arithmetic; the group targets 20% to 22% for fiscal 2030.
Our Numbers
Measured against fiscal 2026 revenue, the segment backlogs differ widely, by our arithmetic: Gas Services €74 billion is 5.1 years of revenue, Grid Technologies €52 billion is 3.7 years, Siemens Gamesa €31 billion is 2.9 years and Transformation of Industry €8 billion is 1.4 years. Gas Services booked €32.8 billion of orders against €14.5 billion of revenue, a ratio of 2.26.
The two buyback programmes add up to €15 billion, about 1.7 times fiscal 2026 free cash flow pre tax of €8.8 billion, by our arithmetic. The new €9 billion is an upper limit through fiscal 2030, not a commitment to spend it all.
Wall St Engine also wrote that Bruch said less than 10% of the backlog is tied to data centers. We did not find that figure in the release or the earnings release we read. If it holds, it caps the data-centre part of the €164 billion at under €16.4 billion, by our arithmetic, so most of the record order book rests on other demand.
For scale, our count of 14 AI data centers above 250 MW of IT power, published earlier today, and our reading of EIA data on US power sales growth, where the commercial sector that includes data centres took 64% of the growth, show where the AI share of this demand sits.
The Structural Read
As we read the cash flow line, customers are funding part of the build: the release says customer advance payments, including reservation fees, contributed to free cash flow pre tax of €8,799 million, and the two buyback programmes total €15 billion, about 1.7 times that figure by our arithmetic.
As we read the outlook, the release ties data centres mainly to North America, where orders rose 70.8% to €27.7 billion. The passages we read do not split those orders or the backlog by customer type, which is why the relayed under-10% data-centre figure cannot be checked against them.
Siemens Energy, Earnings Release Q4 FY 2026, 11 November 2026
“The gas turbine market is expected to remain robust, supported by data centers, government programs for grid stability and coal phase-out, as well as industrial growth”
Three Implications
FOR SHAREHOLDERS The company proposes a dividend of €2.30 a share, against €0.70 for fiscal 2025, and plans to repurchase additionally up to €9 billion of shares through fiscal 2030.
FOR GAS TURBINE BUYERS Gas Services ended the year with a €74 billion backlog, and the earnings release assumes its revenue grows 24% to 26% in fiscal 2027.
FOR THE WIND UNIT Siemens Gamesa reached break-even in fiscal 2026, and the earnings release assumes a 0% to 2% margin and revenue change of negative 3% to negative 1% in fiscal 2027.
The framework argues: “The structural bottleneck isn’t computing, it’s electrons.”
As we read it, Siemens Energy’s results show the supplier side of that bottleneck: a record €164 billion order book, with US orders up 70.8%. The framework predates these results and does not discuss Siemens Energy.
What Is Not Established
The data-centre share comes from a market news account’s summary of Bruch’s remarks, not from the company documents we read, and we could not check its wording against a transcript. The release does not split the backlog by customer type in the passages we read.
The fiscal 2030 figures are targets and the €9 billion is an upper limit. Segment backlogs are rounded to whole billions in the earnings release and do not add exactly to the group figure. The share prices are delayed market data from a third-party feed, not an official close.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Siemens Energy ended fiscal 2026 with a record €164 billion backlog, up 18.2%, and plans up to €9 billion more in buybacks through fiscal 2030 on top of its €6 billion programme. By our arithmetic, its gas unit’s €74 billion backlog is 5.1 years of that unit’s revenue, and the €15 billion of buybacks is 1.7 times a year of free cash flow pre tax.

A note on sourcing. The results, targets, segment figures and the buyback plan come from Siemens Energy’s press release and its Earnings Release Q4 FY 2026, both of 11 November 2026, and the up to €6 billion programme from its Share Buyback 2026 page. We also read Reuters’ report via AOL’s syndication and the Wall St Engine post on X, which is the only source for the data-centre share of the backlog.
