Infineon Expands GaN and AI Power Network as Intel's Soft Guidance Weighs on Chip Stocks

Published on 11/01/2026 at 14:41 | Editorial boerse-global.de

Infineon fell 4.5% amid a semiconductor selloff triggered by Intel's weak Q4 2026 guidance, as the company opened a Warstein lab and deepened NVIDIA ties.

Infineon's shares fell 4.5% on Friday, caught in a broad retreat across semiconductor equities after Intel's downbeat outlook and fresh concerns over AI spending rattled the sector. According to Reuters, the selloff swept through technology names in the US and Asia as well as European chipmakers, with Infineon explicitly among those hit.

The trigger was Intel's guidance for the fourth quarter of 2026: revenue of USD 15 to 16 billion, against analyst expectations of USD 17.1 billion, according to media reports. Those same reports pointed to worries about the AI investments of major cloud companies following Amazon's results as an additional drag on sentiment.

Warstein Lab Building Opens

Away from the market turmoil, Infineon opened a new office and laboratory building in Warstein on Wednesday, designed to house around 350 employees. The new structure includes roughly 1,200 square metres of laboratory space. The site expansion sits alongside several announced projects in power semiconductors and applications for AI data centres.

Should investors sell immediately? Or is it worth buying Infineon?

Villach Bet on 300-Millimetre GaN

At the Austrian site in Villach, Infineon plans to invest around EUR 1.1 billion through 2034 to establish what it describes as the world's first high-volume manufacturing of GaN power semiconductors on 300-millimetre wafers. Production is scheduled to begin by the end of 2027. Company statements indicate EUR 319 million in funding is earmarked for the project under the European Chips Act.

NVIDIA Ties Deepen

On 21 October, Infineon and NVIDIA broadened their collaboration to GaN-based power conversion systems intended for 800-volt DC architectures in AI data centres. The partnership centres on the power supply for those facilities.

Young companies are another focus. On 22 October, UnternehmerTUM Accelerator, Microsoft, Infineon and NVIDIA jointly launched the Physical AI Growth Lab. The free, non-equity programme targets European start-ups in Physical AI, robotics and industrial AI, and runs from January to April 2027. Infineon is one of four partners behind the initiative.

Analyst Move and Results Date

Susquehanna reaffirmed its positive rating on Infineon on 21 October, though analyst Christopher Rolland cut his price target to EUR 85 from EUR 100. Infineon has provisionally scheduled 10 November for the release of its fourth-quarter and full-year 2026 results.
