Penang, July 30, 2020 – Ultra Clean Holdings, Inc. (NASDAQ: UCTT) today announced its expansion into Malaysia and will be setting up a manufacturing facility in the Batu Kawan Industrial Park, Pulau Pinang.

In welcoming UCT’s announcement, the Right Honourable Chief Minister of Penang, Chow Kon Yeow said, “The State government would like to express our deepest appreciation for UCT in choosing Penang for this latest expansion. This is a milestone in Penang’s industry transformation journey and evidence of how major strategic investments translate into technology and economic growth opportunities.”

Leasehold improvements to UCT’s 300,000 square foot facility should begin late in the third quarter this year.
