FREMONT, Calif., Jan. 09, 2024 (GLOBE NEWSWIRE) — ACM Research, Inc. (“ACM”) (NASDAQ: ACMR), a leading supplier of wafer processing solutions for semiconductor and advanced wafer-level packaging applications, today has updated its full year 2023 revenue outlook to a range of $530 million to $545 million, versus a range of $520 million to $540 million as was provided in ACM’s third quarter 2023 earnings release issued on November 7, 2023.

ACM also announced that it expects revenue for the full year 2024 to be in the range of $650 million to $725 million. This expectation is based on ACM management’s current assessment of the continuing impact from international trade policy, together with various expected spending scenarios of key customers, supply chain constraints, and the timing of acceptances for first tools under evaluation in the field, among other factors.

“We expect continued growth in 2024 as we continue on our mission to become a key supplier to major semiconductor manufacturers,” said Dr. David Wang, ACM’s President and Chief Executive Officer. “We anticipate solid investments in mature node capacity by our China-based customers, and we remain committed to expanding our multi-product portfolio. We are making good progress with customers in markets beyond mainland China which we believe will begin to contribute to our business in the coming years.”

ACM plans to release its fourth quarter and full year 2023 financial results in late February 2024. The 2023 revenue outlook included in this press release is preliminary. Actual fourth quarter and full year 2023 revenue results are subject to review and audit procedures by ACM’s independent registered public accounting firm.
