Infineon Sharpens Data-Center Focus as AI Revenue Doubles and Portfolio Sheds Legacy Memory

Infineon says AI-related revenue more than doubled this fiscal year, anchored by an Eaton partnership, a new Bangkok plant and a $1.12bn Winbond deal.

Infineon's ambition in the AI power-supply arena is no longer a side bet. Management disclosed at an investor conference on October 1 that AI-related revenue has more than doubled over the course of the current fiscal year, a jump driven largely by silicon-carbide power semiconductors that sit at the heart of modern server-farm power conversion.

That disclosure landed alongside a string of operational moves that collectively sketch a company narrowing its focus. The Munich-based DAX member is betting that rising electricity demand from artificial intelligence, combined with the re-engineering of industrial power grids, will underpin demand for advanced power chips for years to come.

Eaton Tie-Up Anchors the AI Power Story

Central to the AI push is Infineon's partnership with US industrial group Eaton. Infineon supplies components for Eaton's MVSST 2.0 platform, a medium-voltage solid-state transformer system designed to convert power more efficiently inside data centers and to support DC grids running at voltages of up to 800 volts. The two companies are jointly developing solid-state transformers aimed squarely at that 800-volt DC architecture.

Infineon deepened its own capabilities in this area through the completed acquisition of Bengaluru-based C2i Semiconductors. The Indian developer's team has been folded into Infineon's Power Systems division, where it will contribute expertise in software-defined power supply for data centers. The deal closed just days ago, following an earlier announcement of the transaction.

Bangkok Fab Ramps Toward 1,000 Staff

Capacity is expanding in parallel. On October 1, Infineon opened a new backend manufacturing site in Bangkok alongside Thai Prime Minister Anutin Charnvirakul. The facility currently employs roughly 350 specialists; as the first building reaches full ramp-up, headcount there is expected to climb to about 1,000 highly skilled positions. Infineon frames the plant as a step toward making its global production network more resilient.

The company is also broadening its control-chip and sensor lineup. New additions include the XENSIV TLx49012 family of digital angle sensors for industrial and automotive use, which feature integrated self-calibration. Infineon also unveiled the PSOC Control C3 Performance Line of microcontrollers, built for real-time control and equipped with security functions based on post-quantum cryptography.

Winbond Deal Marks Exit From NOR Flash and F-RAM

Those product launches sit alongside an ongoing reshaping of the group's portfolio. Roughly three weeks ago, Winbond Electronics agreed to acquire Infineon's NOR Flash and F-RAM business in a cash transaction carrying an enterprise value of $1.12 billion. The divestment strips out peripheral operations, freeing capital and management attention for higher-margin growth areas.

Analysts have welcomed the direction. On September 30, Jefferies reaffirmed its Buy rating on the stock with a price target of EUR 96.

Micron's Outlook Lifts the Sector, Then Yields to Macro Pressure

Sentiment around the shares has been volatile. Strong quarterly results and guidance from US memory maker Micron Technology, which flagged sustained demand for AI memory chips, initially buoyed the entire European semiconductor sector and Infineon with it. Company-specific newsflow added to the interest, according to media reports.

The mood shifted as the new trading week got underway, with chip names coming under selling pressure. Market watchers pointed to broader headwinds — rising bond yields, firmer oil prices and inflation concerns in the eurozone — rather than any company-specific bad news. On Monday the stock slipped 1.2% to close at EUR 63.85. By today it was changing hands at EUR 63.19, a modest 1.0% decline on the day.

Despite the recent swings across the technology sector, Infineon shares remain up sharply for the year. The gain since January stands at 69%, reflecting heightened investor interest in the company's strategic repositioning toward data-center and industrial power.
