Brussels Greenlights €319 Million for Infineon's Villach GaN Fab as AI Power Deals Stack Up
Published on 11/09/2026 at 03:50 | Editorial boerse-global.de
Infineon has secured European Commission approval for €319 million in state aid tied to its long-term investment plan in Villach, where the German chipmaker intends to spend roughly €1.1 billion through 2034 on high-volume production of gallium nitride power semiconductors on 300-millimeter wafers. The company has pencilled in the start of production for late 2027. The subsidy is now cleared, while the investment sum and the manufacturing timeline remain part of the announced planning.
The approval lands in the middle of an unusually busy stretch for Infineon, which has spent the past week rolling out partnerships and products aimed squarely at data-centre power and software-defined vehicles.
Three-year supply lock with Vertiv
On Wednesday, Vertiv signed a three-year strategic agreement with Infineon covering the supply of power semiconductors. According to Vertiv, the deal spans silicon- and silicon-carbide-based components, which are to be used in the company's 800 VDC power supply systems, among other applications.
A day later, Infineon and SOLUM put pen to paper on a memorandum of understanding to deepen their cooperation on HVDC power supply solutions for AI data centres. Infineon said the collaboration covers interleaved DC-DC converters, battery backup units and power supplies.
Should investors sell immediately? Or is it worth buying Infineon?
The product side kept pace. On Tuesday, Infineon launched its OptiMOS-7 40 V power MOSFET portfolio, aimed at AI servers, data centres and telecommunications infrastructure — several of the very fields the company has flagged as targets for its power supply business.
Automotive push alongside Qualcomm
On the automotive front, Infineon and Qualcomm Technologies agreed on 2 November to jointly develop a microcontroller subsystem for Qualcomm's Snapdragon Ride reference platforms for central vehicle computers in software-defined cars. The work targets vehicle computing, driver assistance and AI applications inside the car.
Infineon also unveiled the AURIX RC1 family on Wednesday, pitched as a concept for real-time control in software-defined vehicles and for physical-AI applications. Samples of the new family are slated for the first half of 2027.
Goldman lifts reported stake
Investor positioning drew attention too. Goldman Sachs reported a higher aggregate holding including financial instruments of 5.65% in Infineon on 3 November, up from 4.73% previously, according to the voting rights notification. The threshold crossing named in the filing took place on 27 October.
Shares steady after sell-off
The stock stabilised on Friday following an earlier sell-off, as reported by dpa-AFX. Infineon shares rose 1.8% to close at €45.85. The news agency pointed to sector-wide worries about the financing and build-out of AI data centres in the wake of the US midterm elections.

Infineon will also present innovative and energy-efficient solutions for an increasingly intelligent and connected world at electronica 2026 in Munich, running from 10 to 13 November in Hall C3, Stand 502.
For investors, the next hard date is 10 November, when Infineon publishes its results for the fourth quarter and the 2026 financial year.
