ANDOVER, Mass., June 25, 2026 (GLOBE NEWSWIRE) -- MKS Inc. (NASDAQ:MKSI), a global provider of enabling technologies that transform our world, today announced the expansion of its Atotech equipment manufacturing site in Guangzhou, China.

With an investment of USD 25 million, the expansion will add approximately 323,000 square feet of manufacturing and operations space and is expected to double the site’s production capacity upon completion, which is targeted for the fourth quarter of 2027.

This investment reinforces MKS’ ongoing commitment to customers across Asia, where localized manufacturing, speed, and responsiveness are increasingly critical. The expansion is driven by sustained growth in AI-related markets — particularly in semiconductor, advanced packaging, and advanced PCB applications — where customers demand greater scale, faster turnaround, and closer technical collaboration.

The new facility expansion is designed to integrate seamlessly with existing operations, enhancing capabilities across production, final assembly, logistics, and testing and validation. Beyond increased manufacturing capacity, the site will continue to support R&D activities, while strengthening global technology collaboration with customers and original equipment manufacturers.

To support more sustainable operations, the facility will incorporate a photovoltaic power system designed to supply a significant portion of its daytime electricity demand, contributing to improved energy efficiency and long-term sustainable growth.

"Expanding our operations in Asia strengthens our ability to support customers in one of the world’s most dynamic electronics manufacturing hubs," said Dave Henry, Executive Vice President, Global Strategic Marketing and General Manager, Materials Solutions Division. "By increasing capacity, enhancing operational efficiency, and advancing innovation, we are improving responsiveness to customer demand while building a strong foundation to support the next wave of AI-driven growth globally."

"This expansion reinforces Guangzhou’s strategic role within our global manufacturing network," said Tassilo Thuene, Vice President and General Manager, Equipment Business, Materials Solutions Division. "With added capacity, enhanced testing and validation capabilities, and greater operational flexibility, we are well positioned to meet evolving customer requirements and enable the next wave of innovation in advanced electronics and AI-related applications."

The expanded facility is designed to streamline production flows, reduce complexity, shorten lead times, and improve delivery reliability. Once fully ramped, the site is expected to generate significant additional annual output, further strengthening MKS’ position in high-growth electronics markets.
