Infineon Technologies (ISIN DE0006231004) announced a EUR 1.1 billion expansion of its Villach site on October 27, 2026, to build Europe's first high-volume gallium nitride power semiconductor facility on 300-millimeter wafers, according to Infineon Technologies. At Lang & Schwarz on October 28, 2026 at 9:37 a.m. CET, Infineon stock was trading at EUR 52.33, minus 0.49 percent versus the Xetra close of October 27, 2026 at EUR 52.59.

EUR 1.1 billion expands Villach

The investment will upgrade existing cleanroom facilities in Villach, Austria, with spending running through 2034. Production is scheduled to begin by the end of 2027, while the ramp-up will follow market demand, the Infineon Technologies release said.

The project has received approval for up to EUR 319 million in state aid under the European Chips Act. The formal Austrian funding commitment is expected within the stated process, so the full support remains conditional on the applicable criteria.

What does 2.3 times more chips mean?

Infineon says a 300-millimeter wafer can produce 2.3 times as many chips as a 200-millimeter wafer. That gives the project an operational angle beyond capacity: larger wafers can improve manufacturing efficiency while the company targets demand from artificial intelligence data centers, energy infrastructure, electric mobility, robotics and consumer electronics.

The investment also deepens Villach's role as a competence center for power electronics and new semiconductor materials. Infineon said the site currently employs approximately 4,800 people, a historical fiscal-year 2025 figure dated September 30, 2025.

Stock remains below its annual high

At EUR 52.33, the stock stood 41.09 percent below its EUR 88.83 52-week high and within a EUR 31.27 to EUR 88.83 range, based on the October 28, 2026 market snapshot. The next operating test is whether the new capacity can convert gallium nitride technology into volume production without weakening capital discipline.
