FREMONT, Calif., November 05, 2025 (Globe Newswire) – ACM Research, Inc. (“ACM”) (NASDAQ: ACMR), a leading supplier of wafer processing solutions for semiconductor and advanced wafer-level packaging applications, today reported financial results for its third quarter ended September 30, 2025.

“I am pleased to report another strong quarter for ACM. We grew revenue by 32%, and continue to innovate with world-class tools across multiple product lines. We believe the market is moving toward ACM as AI and global datacenter investments are demanding new innovative technology requirements for next generation semiconductor equipment,” said Dr. David Wang, President and Chief Executive Officer of ACM. “We are seeing broad interest in our proprietary horizontal plating technology for panel-level packaging, with plans to deliver our first system in the fourth quarter. Our high-temperature SPM platform is setting new benchmarks as our proprietary nozzle design achieves industry-best performance at 19nm particle size and below, with significantly lower maintenance and no need to clean the outer chamber. The first shipment of our KrF Track platform in the third quarter further expands our SAM into critical lithography-adjacent applications.”

Dr. Wang continued, “In September, our principal operating subsidiary, ACM Shanghai, raised approximately $623 million in net proceeds from its second capital raise on the STAR Market. We plan to deploy this capital to further accelerate development of next-generation tools, complete the Lingang mini-line, and expand production capacity to support future global demand. We have narrowed the range of our guidance for 2025 revenue, and we remain committed to achieve our $4 billion long-term revenue target.”

(1)Reconciliations to U.S. generally accepted accounting principles (“GAAP”) financial measures from non-GAAP financial measures are presented below under “Reconciliation of GAAP to Non-GAAP Financial Measures.” Non-GAAP financial measures exclude stock-based compensation and, with respect to net income (loss) attributable to ACM Research, Inc. and basic and diluted earnings per share, also exclude unrealized gain (loss) on short-term investments.

ACM has narrowed the range of its revenue guidance range for fiscal year 2025 to $875 million to $925 million, versus the prior range of $850 million to $950 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.

•Shipments. Total shipments in the third quarter of 2025 were $263.1 million, up 0.7% from the third quarter of 2024. Total shipments include deliveries for revenue in the quarter and deliveries of first tool systems awaiting customer acceptance for potential revenue in future quarters.

•ACM Shanghai Completed its Private Offering. In September 2025, ACM Shanghai issued 38,601,326 ordinary shares at RMB 116.11 per share, raising net proceeds of RMB 4.4 billion (approximately USD $623 million) after deducting offering-related expenses. As a result of the Private Offering, ACM’s equity interests in ACM Shanghai declined from 81.1% as of June 30, 2025 to 74.6% as of September 30, 2025.

•During the third quarter of 2025, ACM Shanghai paid a cash dividend for a net total of approximately RMB 264.9 million (approximately USD $36.8 million) to the stockholders of ACM Shanghai, including ACM, which owned 81.1% of the outstanding shares of ACM Shanghai at the time.

•Delivered Its First High-Throughput Ultra Lith KrF Track System to a Leading Chinese Logic Wafer Fab Customer. ACM announced the launch of its first Ultra Lith KrF track system, designed to support front-end semiconductor manufacturing. The new system expands ACM’s lithography product line and delivers high-throughput performance, advanced thermal control, and real-time process control and monitoring. The first system was shipped to a leading Chinese logic wafer fab customer in September 2025.

•Unveiled Ultra ECDP Electrochemical Deplating Tool for Compound Semiconductor Gold Etch Processes.

ACM presents non-GAAP gross margin, operating expenses, operating income, net income attributable to ACM Research, Inc. and basic and diluted earnings per share as supplemental measures to GAAP financial measures regarding ACM’s operational performance. These supplemental measures exclude the impact of stock-based compensation, which ACM does not believe is indicative of its core operating results. In addition, non-GAAP net income attributable to ACM Research, Inc. and basic and diluted earnings per share exclude the effect of stock-based compensation and unrealized gain (loss) on short-term investments, which ACM also believes are not indicative of its core operating results. A reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure is provided below under “Reconciliation of GAAP to non-GAAP Financial Measures.”

ACM believes these non-GAAP financial measures are useful to investors in assessing its operating performance. ACM uses these financial measures internally to evaluate its operating performance and for planning and forecasting of future periods. Financial analysts may focus on and publish both historical results and future projections based on the non-GAAP financial measures. ACM also believes it is in the best interests of investors for ACM to provide this non-GAAP information.

While ACM believes these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these non-GAAP financial measures. These non-GAAP financial measures may not be reported by competitors, and they may not be directly comparable to similarly titled measures of other companies due to differences in calculation methodologies. The non-GAAP financial measures are not an alternative to GAAP information and are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures. They should be used only as a supplement to GAAP information and should be considered only in conjunction with ACM’s consolidated financial statements prepared in accordance with GAAP.
