ACM Research Reports Second Quarter 2025 Results
 
FREMONT, Calif., August 06, 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 second quarter ended June 30, 2025.

“Our results for the first half of 2025 reflect good execution across our product portfolio and strengthen our confidence in our long-term growth opportunity in China,” said Dr. David Wang, President and Chief Executive Officer of ACM. “We see continued momentum from our SPM, Tahoe, plating and furnace tools, and we are encouraged by customer engagements across multiple new platforms including Track, PECVD, and panel-level packaging. As a result, we have raised our long-term revenue target for the mainland China market. At the same time, we are making important strides in our global expansion efforts, with several tool deliveries planned to the U.S. during the third quarter.”

Dr. Wang continued, “We recently announced major upgrades to our Ultra C wb Wet Bench cleaning tool. The technology integrates ACM’s patent-pending nitrogen bubbling technology to generate large-sized bubbles with good bubble-density uniformity and enhance the etching rate uniformity in the 3D structure across the wafer. Today, I am pleased to announce we have received repeat orders of this tool for shipment this year and next. The technology is also adaptable to our Ultra C Tahoe platform, with significant application potential for manufacturing advanced 3D NAND, 3D DRAM, and 3D logic devices​. We remain committed to deliver innovative new products to enable our customers to meet the next generation of semiconductor manufacturing challenges as demanded by the Artificial Intelligence (AI) transformation. As a multi-product company with proprietary world-class technology, we remain confident in our ability to drive long-term growth and increase market share in both China and global markets.”

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.


Outlook

ACM is maintaining its revenue guidance range of $850 million to $950 million for fiscal year 2025. 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.
 
Operating Highlights and Recent Announcements
 
Shipments. Total shipments in the second quarter of 2025 were $206.4 million, up 1.9% from the second 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.
 
Upgraded Ultra C wb Wet Bench Cleaning Tool with Patent-Pending N₂ Bubbling Technology. ACM announced major upgrades to its Ultra C wb cleaning tool, featuring a patent-pending nitrogen (N₂) bubbling technique that improves wet etching uniformity by over 50% and enhances particle removal performance for advanced-node applications.
 
Delivery of 1,500th ECP Chamber. ACM delivered an ECP tool to a customer in China, which included ACM’s 1,500th electroplating chamber shipped. This milestone highlights ACM’s continued growth in plating technology adoption and reinforces its leadership in high-performance electroplating equipment for advanced semiconductor manufacturing.
 
Second Quarter 2025 Financial Summary
 
Unless otherwise noted, the following figures refer to the second quarter of 2025 and comparisons are with the second quarter of 2024.

Revenue was $215.4 million, up 6.4%, reflecting modest growth from single wafer cleaning, Tahoe and semi-critical cleaning equipment, and higher sales of ECP (front-end and packaging), furnace and other technologies, and advanced packaging (excluding ECP), services & spares.
 
Gross margin was 48.5% versus 47.8%. Non-GAAP gross margin, which excludes stock-based compensation, was 48.7% versus 48.2%. Gross margin exceeded the high end of ACM’s long-term business model target range of 40% to 45%. ACM expects gross margin to vary from period to period due to a variety of factors, such as product mix, currency impacts and sales volume.
 
Operating expenses were $72.8 million, an increase of 22.9%. Operating expenses as a percentage of revenue increased to 33.8% from 29.2%. Non-GAAP operating expenses, which exclude the effect of stock-based compensation, were $63.4 million, up 38.8%. Non-GAAP operating expenses as a percentage of revenue increased to 29.4% from 22.5%.
 
Operating income was $31.7 million, compared to $37.6 million. Operating margin was 14.7% compared to 18.6%. Non-GAAP operating income, which excludes the effect of stock-based compensation, was $41.5 million, compared to $51.9 million. Non-GAAP operating margin, which excludes stock-based compensation, was 19.3% compared to 25.6%.
 
Unrealized gain on short-term investments was $2.7 million, compared to an unrealized gain of $1.0 million. Unrealized gain reflects the change in market value of the investments by ACM’s principal operating subsidiary, ACM Research (Shanghai), Inc. The value is marked-to-market quarterly and is excluded in the non-GAAP financial metrics.

Use of Non-GAAP Financial Measures
 
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.
