AIXTRON to expand global footprint with new plant in Malaysia

Herzogenrath, March 25, 2026 – AIXTRON SE (FSE: AIXA), a leading supplier of deposition equipment for compound semiconductors, is taking an important step to strengthen its global competitiveness. The company has decided to build a new manufacturing facility in Malaysia in order to tap into the fast growing semiconductor equipment ecosystem in South East Asia.

Strengthening global competitiveness

AIXTRON plans to manufacture some of its 100/150/200 mm products in the new plant in the Penang region, mostly to address customers in Asia. The new location will include assembly & test, engineering support and local purchasing capabilities. This will allow local assembly of some of AIXTRON’s products, and sourcing of many parts from the local supply chain of module and component makers. The modular factory design allows for future expansion with little additional investment. With the plant in Malaysia, AIXTRON is making a big step to tap one of the leading ecosystems of the semiconductor equipment industry and follows other leading global semiconductor equipment makers in terms of global footprint expansion.

Dato’ Loo Lee Lian, CEO of InvestPenang shares her excitement about the company’s expansion into Malaysia, stating, “AIXTRON’s decision to build a new facility in Penang underscores our region’s growing reputation as a premier destination for advanced technology investments. This new facility highlights Penang's attractiveness as a strategic hub for innovation and manufacturing, reflecting the company's confidence in our highly skilled workforce and favorable business environment.”

“With this step, AIXTRON is implementing a best-practice strategy of the global semiconductor supply industry and leveraging the excellently developed local ecosystem. Overall, this represents a clear growth step for us, strengthens our position in the Asian market. We remain dedicated to our European locations in Herzogenrath, Germany, and Cambridge, UK. Both locations are central pillars for research, development, and also production, especially due to many strong and specialized suppliers. The plant in Malaysia complements the strengths of the existing locations and allows to leverage “the best of both worlds” by adding access to the South East Asia supply chain. No personnel reduction is planned in Europe as a result of this”, says Dr. Felix Grawert, CEO of AIXTRON SE.

2026 financials unchanged // EUR 40 million capex for the new facility

The capex for the new site is estimated at around EUR 40 million, to be spent in H2/2026 and H1/2027. The plant is expected to start operation in the spring of 2027 with first shipments expected in the second half of 2027. The start-up costs expected in 2026 in connection with preparing for production will not affect the forecast for fiscal year 2026.
