Siemens Energy (Educational): Two Tailwinds, One 22% Drawdown

Wall Street has already raised its earnings estimates for Siemens Energy (Frankfurt: ENR; US ADR: SMERY). The stock trades at 17.4x FY2028 earnings and 11.4x FY2030. The market is paying a peak-of-cycle price for a company the Street models growing every year through 2030.

That gap between price and expectations is the money we’re here to make.

One question at the end: does the same logic apply to Micron? Same logic, different risk shape.

What Siemens Energy Actually Sells

Spun out of Siemens AG in 2020, the company has four segments.

Gas Services sells heavy-duty and industrial gas turbines, plus decades of maintenance after the sale. Q3 FY26 revenue €3.76bn, margin 17.3%. This is the cash cow and the core beneficiary of AI data-center power demand.

Grid Technologies sells transformers, high-voltage switchgear and HVDC transmission equipment. Q3 revenue €3.62bn, margin 19.9%, the highest of the four. A direct play on grid build-out.

Transformation of Industry sells compressors, electrolyzers and other industrial equipment. Q3 revenue €1.53bn, margin 14.3%. The company has announced plans to carve it out and sell it.

Siemens Gamesa sells wind turbines. Q3 revenue €2.74bn, margin 2.7%. The drag on the group; it lost several billion euros over the past three years.

Four facts to anchor on:

• Backlog of €162bn, roughly 3.5 years of revenue.
• Gas turbine lead times of 3 to 4 years, up to 7 for some models.
• Service contracts averaging 17 years.
• FY26 free cash flow expected near €8bn, being returned through a €6bn buyback program.

How does it get paid on AI today when deliveries are years out? Five mechanisms:

1. Customers pay deposits and non-refundable slot reservation fees at the time of order. Cash lands now, not at delivery.
2. Revenue is recognized on a percentage-of-completion basis. Orders booked in 2026 start flowing into revenue in 2027, not at delivery in 2030.
3. Roughly 20% of Q3 gas turbine orders came directly from data centers; with Middle East projects, about half.
4. Small industrial turbines like the SGT-800 ship within two years. They are the “fast power” product for data centers.
5. Grid transformers carry 1-to-2-year lead times, giving shorter-cycle exposure to AI power demand.

Five Concepts You Need First

1. P/E and forward P/E

P/E equals share price divided by earnings per share. At €145.36 and EPS of €6.34, P/E is 22.9x. In plain terms: at today’s earnings, it takes 22.9 years to earn back what you paid.

Forward P/E uses expected earnings for a future year. Analysts forecast EPS several years out; the average of those forecasts is “Street consensus” (media shorthand for Wall Street is “the Street,” so a Street estimate is simply the consensus).

Consensus for Siemens Energy (fiscal year ends September):

• FY26 EPS €4.38, 33.2x
• FY27 €6.34, 22.9x
• FY28 €8.33, 17.4x
• FY29 €10.41, 14.0x
• FY30 €12.70, 11.4x

If the Street is right about 2030, €145 today buys a company at 11.4x 2030 earnings.

For context, Siemens AG trades at 27x. GE Vernova, the closest US peer, trades at 41x 2027 earnings and 29x 2028.

For a company still compounding earnings above 25% a year, 11x is a utility multiple (assuming you’re willing to hold for years).

2. Price = earnings × multiple

Any stock move splits into two parts: earnings changed (the company makes more or less), or the multiple changed (what the market pays per euro of earnings).

Siemens Energy has fallen 22.5% since April. Over that stretch, 2026 and 2027 estimates went up (14 of 20 brokers raised in the past 30 days). So the entire 22.5% is multiple compression: 40x 2027 earnings in April, 23x now.

Why did the multiple compress? Rates. The 10-year Bund yield rose from 2.87% at the start of the year to 3.57% in September, a 17-year high. The correlation between European equities and bond yields now sits at −70%, the strongest since the 1990s.

Higher rates make investors less willing to pay up for distant earnings, because discounting makes those future euros worth less today.

Do we need rates to stop rising? Earnings don’t; the orders are signed. The multiple does.

3. The duration gap

This is the concept the whole trade hangs on.

The disagreement between the Street and the market is not about how much Siemens Energy earns in 2027. It’s about how long the good years last.

Take a company earning 6 next year, then 8, 10 and 12. If you believe it holds 12 or keeps growing, you’ll pay 20x or more. If you believe 12 is the peak and earnings fall back to single digits, you’ll pay 10 to 12x, because you know you’re looking at peak-cycle earnings.

At €145, the stock is priced by the second investor. The market believes the 2027 and 2028 numbers but not that 2029 and 2030 can hold.

Duration, in this case, is the length of that high-earnings window.

The market assumes a short one; the Street’s models assume a long one. That’s the gap.

4. Why the market thinks this way: the 2001–02 turbine bust

This is market memory, and the strongest bear case.

From 1998 to 2001, US power deregulation led merchant developers such as Calpine, Dynegy and Enron to borrow heavily and order gas turbines in bulk, betting power prices would stay high. GE’s turbine orders peaked in 2001. In 2002, power prices collapsed, developers went bankrupt, and orders were canceled at scale. GE’s heavy-duty turbine shipments fell from 323 units in 2002 to 175 in 2003, and GE collected $1.5bn in cancellation fees. Many projects under construction were abandoned; completed plants ran at low utilization.

The market learnt three lessons:

• Turbine demand is cyclical, not permanent.
• Backlog is not revenue; it can be canceled.
• Equipment stocks peak one to two years before orders peak, because smart money leaves early.

So when investors today see record turbine orders with 7-year lead times, some don’t see a golden age. They see 2001 again. That’s why they pay 11x.

Side note: does this remind you of memory stocks like Micron? Keep reading. The Micron analysis is further down, including why the stock has stalled recently.

5. What’s different this time

In 2001 the buyers were leveraged merchant developers; today they are utilities and independent power producers with long-term data-center contracts. In 2001 orders required almost no money down; today they require non-refundable reservation fees and deposits. In 2001 demand rested on a bet that power prices would rise; today it rests on electrification, coal retirements and real load growth from AI data centers. In 2001 suppliers expanded capacity aggressively; today GE Vernova and Siemens Energy are expanding far below their backlogs (GEV has signed 116 GW against roughly 20 GW of annual capacity). In 2001 there were no long-term service contracts; today they average 17 years.

To be fair, there are similarities. The AI build-out leans more on debt each year: hyperscalers, data-center SPVs and neoclouds raised $346bn this year, double last year, and AI-linked bonds trade at wider spreads than traditional issuers. If that financing layer cracks, orders stop first. That’s why I keep roughly 20% probability on the downside scenario.

Germany’s Fiscal Turn Is the Second Tailwind

The debt brake

Germany’s constitution has carried a “debt brake” (Schuldenbremse) since 2009. It caps federal structural borrowing at 0.35% of GDP a year and effectively bars the states from borrowing at all. It made Germany one of the least indebted developed economies, and it left the country more than a decade behind on roads, bridges, rail and grid.

The March 2025 reform

After the February 2025 election, before the new Bundestag was seated, Merz used the outgoing parliament’s two-thirds majority to amend the constitution (512 votes to 206). Three changes.

First, a defense carve-out. Defense and security spending above 1% of GDP (including intelligence services and Ukraine aid) sits outside the debt brake, with no borrowing cap. German GDP is about €4.3tn, so 1% is roughly €43bn. Total 2026 defense spending is about €108bn, meaning roughly €65bn is debt-financed. The target is more than €150bn a year by 2029.

Second, a €500bn special infrastructure fund. It sits outside the debt brake, with 12 years to commit. It splits three ways: €300bn to the federal government for transport, rail, bridges, digitalization, hospitals and education; €100bn to the Climate and Transformation Fund (KTF) for hydrogen, building efficiency and grid-related subsidies; and €100bn to states and local governments (40% states, 60% municipalities).

Third, the states can now borrow, up to 0.35% of GDP combined, versus zero before.

Where the money has gone and why it’s slow

The 2026 federal budget includes €126.7bn of investment, €48.9bn of it from the special fund. But only about 12% of the fund has reached the municipal level, and municipalities carry more than half of Germany’s public investment. KfW’s October survey put the municipal investment gap at a record €231bn.

That is why German fiscal beneficiaries have diverged so sharply. Defense and federal mega-projects are already drawing money (Hochtief’s backlog is at a record). Local infrastructure money hasn’t arrived (Heidelberg Materials says the recovery in German cement demand has stalled).

Why this gives us a structural edge

Read the chain carefully. The money is on the table; the learning is on you.

1. German manufacturing PMI now sits above the US (53.9 in September).
2. The whole world worries that governments are out of money. Germany is one of the few that can raise spending at scale.
3. German fiscal beneficiaries have had earnings estimates raised 13% to 14% this year, yet the stocks are down more than 20%.
4. So you pay a low-teens P/E for a basket of companies whose earnings growth over the next 12 to 24 months matches US equities.

After several days of screening, the fiscal beneficiaries cluster in building materials, industrials and logistics equipment, mostly MDAX mid-caps, not defense names like Rheinmetall at 60x-plus.

How Siemens Energy ties in

Siemens Energy’s FY25 German revenue was €3.8bn, just 9.7% of the total. US revenue was €8.7bn, 22% of revenue and 32% of orders. The money comes from the US and the Middle East, not Germany.

German fiscal policy reaches the company through three channels, none of them fast.

Channel one: the gas power plant strategy (Kraftwerksstrategie). Germany wants to exit coal and back up intermittent wind and solar, so it plans new dispatchable gas plants. An agreement in principle with the European Commission came in January 2026, with a first tender of 12 GW. The draft law (StromVKG) was published April 27; tenders were scheduled for September and December 2026, plants online before 2031, on 15-year contracts. EU state-aid approval is still pending and the tenders are slipping. Assume 10 GW built entirely as combined-cycle plants: the turbine content is worth €3bn to €4bn, and at a 42% share of the heavy-duty market Siemens Energy would take roughly €1.5bn, under 1% of backlog, but with 15 years of service revenue attached. Orders in 2027 at the earliest; revenue from 2029.

Channel two: grid expansion. The four transmission operators (TenneT, Amprion, 50Hertz, TransnetBW) plan €360bn to €390bn of investment through 2045. TenneT Germany spent a record €10bn in 2025. Siemens Energy has an innovation partnership with all four and completed phase one in August. This money comes from regulated network tariffs, not the €500bn fund, so it doesn’t depend on fiscal politics and is already flowing.

Channel three: energy independence. The Russia-Ukraine war and the Iran conflict forced Europe to accept it needs its own generation and grid capacity. This underpins long-term demand without translating into specific orders.

Bottom line: German fiscal policy is icing for Siemens Energy, not the cake. It is still the highest-quality name in my German fiscal screen, precisely because its earnings don’t depend on the fiscal transmission working.

What Germany adds is duration. It makes 2029 to 2031 revenue more secure, and those are exactly the years the market refuses to pay for.

Where the Alpha Comes From

The Street is already ahead of management

The usual route to alpha runs: Street too conservative → company beats → analysts raise → stock rises. Buy before the upgrades.
