SCHEDULE 13D

SCHEDULE 13D

This Statement on Schedule 13D relates to the shares of Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock”), of ACM Research, Inc., a Delaware corporation (the “Company”). The address of the Company's principal executive offices 42307 Osgood Road, Suite I, Fremont, CA 94539.

The shares of Class A Common Stock reported herein as being beneficially owned by each Reporting Person were acquired by such Reporting Person pursuant to transactions consummated prior to the Company’s initial public offering (the “IPO”) and the March Stock Dividend (as defined below). Neither Reporting Person has acquired any shares of Class A Common Stock since the closing of the IPO, other than as a result of the March Stock Dividend.

The shares of Class A Common Stock beneficially owned by SHSTVC, other than those acquired pursuant to the March Stock Dividend, were acquired upon the conversion (in connection with the closing of the IPO) of shares (the “Series E Shares”) of the Company’s Series E convertible preferred stock, par value $0.0001. SHSTVC acquired the Series E Shares prior to the IPO in connection with SHSTVC’s disposition to the Company of its equity interests in ACM Research (Shanghai), Inc. (“ACM Shanghai”), an operating subsidiary of the Company (“ACM Shanghai”). The parties to such transaction valued the equity interest in ACM Shanghai at approximately $5,800,000 in connection with such transaction.

The shares of Class A Common Stock beneficially owned by PDSTVC, other than those acquired pursuant to the March Stock Dividend, were acquired by Pudong Science and Technology (Cayman) Co., Ltd. (“PST”), an indirect wholly-owned subsidiary of PDSTVC, in September 2017 in connection its disposition of its equity interests in ACM Shanghai to the Company. The parties to such transaction valued such shares of Class A Common Stock at $7.50 per share in connection with such transaction.

On March 23, 2022, the Company paid a stock dividend of two shares of Class A Common Stock for each share of outstanding Class A Common Stock (the “March Stock Dividend”) to holders of record, including the Reporting Persons, of such Class A Common Stock.

The information set forth in Items 3 and 6 is incorporated herein by reference.

The Reporting Persons have acquired the shares reported herein for investment purposes.

Yinan Xiang, an employee of an affiliate of SHSTVC, serves on the board of directors of the Company (the “Board”). Ms. Xiang replaced Xiao Xing (a former member of the Board) who was nominated to the Board as SHSTVC’s designee pursuant to a voting agreement that is no longer in effect. At the time of such replacement SHSTVC did not have, and SHSTVC does not currently have, a contractual right to designate or nominate a director of the Company.

Depending on various factors and subject to the obligations described herein, the Reporting Persons may take such actions with respect to their investments in the Company as they deem appropriate, including, without limitation, (i) acquiring additional shares of Class A Common Stock, directly or indirectly, in the open market or in private transactions on such terms and at such times as it deems appropriate, (ii) selling some or all of their beneficial or economic holdings, (iii) engaging in hedging or similar transactions with respect to the securities relating to the Company and/or (iv) otherwise changing their intention with respect to any and all matters referred to in this Item 4 of Schedule 13D.

Each of the Reporting Persons is a member of a “group” for purposes of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the other Reporting Person as a result of the Coordination Agreement (as defined in Item 6 below). Such group beneficially owns, in the aggregate 6,797,238 shares of Class A Common Stock, or approximately 12.39% of the outstanding shares of Class A Common Stock.
