ACM Research Reports Second Quarter 2026 Results

FREMONT, Calif., August 07, 2026 (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, 2026.

“We delivered a strong second quarter, with revenue and shipments both increasing 36% year over year,” said Dr. David Wang, President and Chief Executive Officer of ACM. “Revenue growth was led by the ECP and advanced packaging categories, which grew 168% and 153%, respectively, reflecting the growing contribution of our broader product portfolio. During the quarter, we shipped our 2,000th ECP chamber, an important milestone that demonstrates the increasing adoption of our ECP technology in high-volume manufacturing of logic, memory and 3D packaging. We also delivered good profitability, and ended the quarter with $1.0 billion in net cash, providing significant financial strength to support our long-term growth strategy.”

Dr. Wang continued, “Customer demand as demonstrated by increased order activity provides us with good visibility for the remainder of 2026. We see 2026 as a ‘Big Year’ for new products as we proceed with customer evaluations and product ramps across multiple platforms, including SPM Cleaning, Track, PECVD and horizontal panel-level plating for advanced packaging. At the same time, we are expanding engagement with global customers and making solid progress at our Oregon facility. We are raising our full-year 2026 revenue outlook for 25% to 30% growth. We remain confident in our ability to outgrow the market through new product cycles, market share gains and increasing contributions from global markets as we execute toward our long-term revenue target of $4 billion.”

Exhibit 99.1

Outlook

ACM has raised its revenue guidance range to $1.125 billion to $1.175 billion for fiscal year 2026, from the prior range of $1.08 billion to $1.175 billion. 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 2026 were $281.5 million, up 36.4% when compared to the second quarter of 2025. Total shipments include deliveries for revenue in the quarter and deliveries of first tool systems awaiting customer acceptance for potential revenue in future quarters.

•Shipment of the 2,000th Electroplating Chamber. ACM shipped its 2,000th electroplating chamber, following shipment milestones of 500 chambers in 2022 and 1,500 chambers in 2025. The achievement underscores the continued commercial expansion and growing market recognition of ACM's electroplating solutions.

•Presented Proprietary High-Temperature SPM Cleaning Technology at SPCC 2026. ACM presented its proprietary high-temperature SPM cleaning technology at the Surface Preparation and Cleaning Conference (SPCC) 2026, showcasing particle performance of fewer than 15 particles at 15nm without requiring periodic DI water chamber cleaning. The technology is designed to improve yield and lower maintenance requirements for advanced GAA logic, DRAM and HBM applications.

•Expansion of the Ultra C Tahoe Wet Processing Platform. ACM has expanded its Ultra C Tahoe system into a multi-process wet processing platform, by adding advanced wet etch and monitor wafer reclaim applications for logic and memory manufacturing. The expanded platform has been adopted by leading semiconductor manufacturers, and the Tahoe Recycle application is running in volume production at customer facilities. This expanded Tahoe platform demonstrates the versatility of our hybrid architecture and its scalability for advanced semiconductor manufacturing. ACM will continue to drive world-class process performance and integrating environmental benefits into product development to help make advanced semiconductor manufacturing more efficient and sustainable.

•Received Orders for the Ultra ECP ap-p Tool. ACM received the first production order for one 510 × 515 mm Ultra ECP ap-p tool from an existing advanced packaging customer in mainland China, with delivery scheduled for the first half of 2027. ACM also received an evaluation order for one 310 × 310 mm tool from a new leading panel-manufacturer customer based in Asia, with delivery scheduled for the fourth quarter of 2026.

•Second Quarter 2026 Financial Summary

Unless otherwise noted, the following figures refer to the second quarter of 2026 and comparisons are with the second quarter of 2025.

•Revenue was $292.9 million, up 36.0%, primarily driven by higher sales of ECP (front-end and packaging), furnace and other technologies, and advanced packaging (excluding ECP), services & spares, partially offset by lower sales of single-wafer cleaning, Tahoe and semi-critical cleaning tools.

•Gross margin was 46.0% versus 48.5%. Non-GAAP gross margin, which excludes stock-based compensation, was 46.0% versus 48.7%. Gross margin was above the mid-point of ACM’s long-term business model target range of 42% to 48%. 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 $84.9 million, an increase of 16.6%. Operating expenses as a percentage of revenue decreased to 29.0% from 33.8%. Non-GAAP operating expenses, which exclude the effect of stock-based compensation, were $78.5 million, up 23.9%. Non-GAAP operating expenses as a percentage of revenue decreased to 26.8% from 29.4%.

•Operating income was $49.7 million, compared to $31.7 million. Operating margin was 17.0% compared to 14.7%. Non-GAAP operating income, which excludes the effect of stock-based compensation, was $56.3 million, compared to

- 2 -

Exhibit 99.1

$41.5 million. Non-GAAP operating margin, which excludes stock-based compensation, was 19.2% compared to 19.3%.

•Unrealized gain on short-term investments was $69.6 million, compared to an unrealized gain of $2.7 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.

•Income tax expense was $13.5 million, compared to $1.9 million. The change in tax expense primarily resulted from the tax effect of an increase in operating profit for the period.

•Net income attributable to ACM Research, Inc. was $89.0 million, compared to $29.8 million. Non-GAAP net income attributable to ACM Research, Inc., which excludes the effect of stock-based compensation and unrealized gain on short-term investments, was $44.5 million, compared to $37.3 million.

•Net income per diluted share attributable to ACM Research, Inc. was $1.23, compared to $0.44. Non-GAAP net income per diluted share, which excludes the effect of stock-based compensation and unrealized gain on short-term investments, was $0.61, compared to $0.55.

•Cash and cash equivalents, plus restricted cash and short-term time deposits were $1.36 billion at June 30, 2026, compared to $1.25 billion at March 31, 2026. Net cash, which excludes short-term and long-term borrowings, was $1.0 billion at June 30, 2026, compared to $924.2 million at March 31, 2026.

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

- 3 -

Exhibit 99.1

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.
