AIXTRON SE to expand global footprint with new plant in Malaysia

Herzogenrath, March 25, 2026 – AIXTRON SE (FSE: AIXA, ISIN DE000A0WMPJ6) today decided to expand the company's international production and supply chain structure by establishing a new production plant in Penang, Malaysia. With this measure, the company aims to access Southeast Asia’s strong semiconductor equipment ecosystem.

 A total investment of around EUR 40 million is planned for the construction of the new plant in 2026 and 2027. The new site will house assembly and testing facilities, provide engineering support, and establish local procurement capabilities.

The production ramp-up in Malaysia will take place step by step. First shipments of tools from the new plant are expected by the end of 2027. The start-up costs expected in 2026 in connection with the ramp-up of production will not affect the guidance for fiscal year 2026.

The existing European sites in Herzogenrath (Germany) and Cambridge (United Kingdom) will remain central development and production sites and will be complemented by the new site.
