FREMONT, Calif., Aug. 17, 2021 (GLOBE NEWSWIRE) -- ACM Research, Inc. (ACM) (NASDAQ: ACMR), a leading supplier of wafer cleaning technologies for advanced semiconductor devices, today is providing an update on the status of the proposed initial public offering (the STAR Market IPO) and listing of shares of ACMs operating subsidiary ACM Research (Shanghai), Inc.

The China Securities Regulatory Commission (CSRC) has indicated that ACM Shanghai has received approval for its STAR Market IPO registration and will soon enter the issuance process for the STAR Market IPO.

We are confident that the STAR Market listing, combined with the continued listing of ACMs Class A common stock on the Nasdaq Global Market, can accelerate our mission to become a global player in the semiconductor equipment industry.
