Stack step

Stack layer

Power (the chips that convert grid electricity into the low-voltage power an AI processor can use: silicon, silicon carbide and gallium nitride switches inside power supply units, rack power shelves and circuit breakers)

Status

Tightening (Infineon says it could not meet all customer requests in fiscal 2026, raised power semiconductor prices twice, and customers are now reserving capacity years ahead)

Market

Global, led by US data center operators; Infineon fabs in Dresden (Germany), Villach (Austria) and Kulim (Malaysia), backend in Bangkok and Melaka

Event date

10 Nov 2026 (fiscal 2026 results and fiscal 2027 outlook, with the press and analyst calls the same morning)

Confidence

Admitted (Infineon results release and management statements on the 10 Nov calls)

Infineon expects its sales of power chips for data centers to rise from €2.2 billion to close to €4 billion in the year to September 2027, backed by more than €10 billion of multi-year supply deals and capacity reservations, which tells us the power conversion step inside the AI rack is now being booked years ahead, the way memory and packaging already are.

## What happened?

- **The results:** On 10 November 2026 Infineon reported fiscal 2026 revenue of €16.353 billion, up 12% on the year, with a record fourth quarter of €4.706 billion and a Segment Result margin of 23.8% in that quarter. Its fiscal year ended on 30 September.
- **The data center line:** On the same day chief executive Jochen Hanebeck said revenue from power supply solutions for AI data centers rose to €1.7 billion in fiscal 2026, more than doubling again and now slightly more than 10% of group revenue. Power supplies for classical data centers added about €500 million. Infineon expects the two together to reach close to €4 billion in fiscal 2027, and says it was unable to meet all customer requests in fiscal 2026.
- **The bookings:** Hanebeck said the combined revenue volume of multi-year supply arrangements and capacity reservations, both signed and under negotiation, has now passed €10 billion. Chief financial officer Sven Schneider said these are mostly power semiconductors in silicon, silicon carbide and increasingly gallium nitride.
- **The group outlook:** Infineon forecasts fiscal 2027 revenue of about €20 billion, growth of more than 20%, with a Segment Result margin in the mid-twenties percentage range and investments of €3.0 billion to €3.5 billion.

## Why does it matter?

**The direct signal: power conversion is now a bottleneck you reserve.** Every watt an AI processor uses has to be stepped down from grid voltage several times on its way into the chip. Each step uses power switches, and as racks move toward the 800-volt direct current designs Hanebeck described on the call, the switches shift toward silicon carbide and gallium nitride. Infineon's message is that customers are no longer buying these parts quarter by quarter. They are signing multi-year arrangements and reserving capacity, which is the same move buyers made earlier for memory and advanced packaging.

**The second-order signal: the money arrives before the data hall is finished.** Power supply units and rack power shelves are bought when the servers are built, not when a campus is energised. So the order book at a power chip maker fills at the server and rack stage, often months before the hall that will house the racks has its grid connection. That is why a company like Infineon can report record data center sales while many AI campuses are still waiting on power. Our [purchase commitment explainer](https://www.sotkn.com/explained/purchase-commitment-explained/) covers why a cheque gets signed before a rack is live; this is the same logic one layer further down.

**Pricing has moved too.** Chief operating officer Ulrich Spiesshofer said Infineon raised power semiconductor prices twice in fiscal 2026, in April and July, and expects a positive price environment in fiscal 2027\. He said the shortage now reaches beyond power semiconductors into related product segments. A supplier that can raise prices while customers queue for capacity is describing a tight step, not an easy one.

**The pattern.** This matches what memory makers have said this autumn: buyers want contracted supply for 2027 and beyond. The difference is the product. Power chips are cheap per unit next to an accelerator, but there are a great many of them in every rack, and without them the accelerator does not switch on.

## What does it change?

**Near term (to the end of fiscal 2027 in September 2027):** Infineon has to deliver the step-up. Our arithmetic: moving from €2.2 billion to close to €4 billion is growth of roughly 80% in one year. Schneider gave a useful check on the call: Infineon booked about €800 million of AI revenue in the fourth quarter alone. Four quarters at that rate is about €3.2 billion before any growth, so the near-€4 billion target assumes solid rather than extreme growth from the current run rate. The question is supply, not demand. The investment plan names the bottlenecks it is paying to clear: tools for the fourth manufacturing building in Dresden, more silicon carbide capacity in Kulim, Malaysia, and the start of gallium nitride production on 300-millimetre wafers in Villach, Austria.

**Longer term (2028 and after):** the bigger wafers are the lever. Infineon said on 9 November it has processed 300-millimetre silicon carbide wafers into working power devices at Villach, using existing silicon tools, and that a 300-millimetre wafer gives 2.3 times as many chips as a 200-millimetre one. It has not given a date for volume production. If that ramp happens, the cost of the silicon carbide switches used in data center power should fall; until it does, capacity stays the constraint.

**Who carries the cost.** Infineon's own cash shows the price of keeping up. It forecasts free cash flow of about €1.8 billion in fiscal 2027, while investing €3.0 billion to €3.5 billion. Investing.com reported that analysts had expected about €2.26 billion of free cash flow. In plain terms, the supplier is spending ahead of the orders it has been promised.

**What the numbers do not tell us.** Infineon did not split the €10 billion by customer, by year or between signed and still-in-negotiation deals, and it has stopped reporting its order backlog. Schneider said the backlog would have been higher than in the previous quarter. So the €10 billion is a statement of demand intent, not a contracted revenue schedule.

## What should we watch next?

- **24 to 25 November 2026:** Infineon is listed at the Goldman Sachs European AI and Semis Symposium in London, per its financial calendar. Any update on how much of the €10 billion is signed rather than in negotiation would firm up the catalyst.
- **3 February 2027:** Infineon's first-quarter fiscal 2027 results (date marked preliminary). The company guided about €4.6 billion of revenue and stable Power Systems revenue, which it calls better than usual seasonality. A miss in Power Systems would be the first sign the supply ramp is running late.
- **Price talks:** Spiesshofer said volume and price negotiations with major customers are under way and results will be announced when they finish.
- **What would weaken the catalyst:** a slowdown in rack builds at US data center operators, which Infineon says are a good portion of its AI business; Chinese competitors gaining in Chinese data centers, which management acknowledged as a question; or the 300-millimetre ramps in Villach slipping.

## Also on the tape

- **9 Nov:** Infineon processed 300-millimetre silicon carbide wafers into working power devices at its Villach fab, with no volume production date yet (Infineon).
- **10 Nov:** The EU's AI gigafactories scheme told bidders to resubmit all tenders for technical reasons; the deadline for medium gigafactories is 6 December 2026 and for large ones the start of February 2027 (DatacenterDynamics).
- **10 Nov:** Firmus told a Tasmanian parliamentary inquiry it would run diesel generators only in emergencies, while appealing a council condition on the 276 backup generators at its Long Reach site (ABC News).
- **9 Nov:** TSMC said it remains focused on logic foundry work after a report that Nvidia asked it to make 3D DRAM (Dataconomy).

## FAQ

**What does Infineon sell into AI data centers?**  
Power semiconductors and controllers that convert and protect electricity on its way from the grid to the processor: parts for power supply units, rack power shelves, voltage regulation near the chip, and semiconductor circuit breakers. It does not make AI processors.

**Is the €10 billion already contracted?**  
No. Infineon says the figure combines agreements already signed and those still being negotiated, and it has not said how the two split.

**Why does gallium nitride matter here?**  
Gallium nitride switches handle high power in less space with lower loss, which suits the 800-volt power designs being planned for next-generation AI racks. Infineon is starting gallium nitride production on 300-millimetre wafers in Villach and works with Nvidia on gallium nitride power conversion.

**Does US opposition to data centers change the outlook?**  
Hanebeck said the debate is mostly an American topic and expects data center building to spread to other regions. Infineon did not cut its outlook for it.

**One-line takeaway:** Infineon's near-€4 billion data center power outlook and €10 billion of reservations show the power conversion step in the AI rack is now booked years ahead, and the test is whether Dresden, Kulim and Villach can ship it on time.
