FREMONT, Calif., May 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 first quarter ended March 31, 2026.

"We are off to a solid start in 2026, with revenue of $231 million, up 34% year-over-year, and shipments of $241 million, up 54% year-over-year. Growth in the quarter was driven by strong performance in ECP and advanced packaging applications, reflecting increasing customer adoption of our differentiated technologies in high performance applications," said Dr. David Wang, President and Chief Executive Officer of ACM. "This quarter, at Semicon China, we announced the ACM Planetary Family, a unified portfolio that reflects ACM's status as a global, multi-product company, serving a broad range of semiconductor manufacturing steps."

Dr. Wang continued, "We expect 2026 to be a big year for new products at ACM. Our R&D over the past 5 years, together with our internal Lingang mini-line, is paying off with industry-leading offerings across several product categories enabling our global customers to solve their evolving production challenges. We expect incremental revenue contribution from Tahoe, single-wafer SPM and vertical furnace, and increased evaluations in our panel-level horizontal plating, low-pressure panel-level flux cleaning, track, and PECVD platforms. We are also taking additional steps to expand our capabilities in global markets, including the proposed Hong Kong listing of ACM Research (Shanghai), Inc., ACM's principal operating subsidiary ("ACM Shanghai") and the ramp-up of our Oregon facility later this year."

"We are maintaining our 2026 revenue outlook for 21%-30% growth, supported by new product cycles, market share gains, and increasing engagement from global customers," Dr. Wang concluded, "Our business has momentum, our strategy is working, and we remain firmly committed to delivering world-class innovative solutions to meet current and future requirements across a broad and expanding global customer base."

Outlook

ACM is maintaining its revenue guidance range of $1.08 billion to $1.175 billion for fiscal year 2026. 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 first quarter of 2026 were $240.7 million, versus $156.7 million in the first quarter of 2025, up 53.6%. Total shipments include deliveries of repeat tools and deliveries of first tools awaiting customer acceptance for potential revenue recognition in future quarters.

Shipped First PECVD SiCN System. ACM announced that it has shipped its first plasma-enhanced chemical vapor deposition (PECVD) silicon carbonitride (SiCN) system to a leading semiconductor manufacturer. As part of the Saturn Series within the ACM Planetary Family, the system met customer-defined process specifications in ACM's Lingang lab and has been delivered to the customer site for final validation. Targeting advanced back-end-of-line (BEOL) requirements, the system further expands ACM's capabilities in advanced packaging applications.

Shipment of Advanced Packaging Equipment to Leading Global Customers. ACM completed, on schedule, shipments of its Ultra C vac-p panel-level advanced packaging vacuum cleaning system to a leading global semiconductor packaging manufacturer outside mainland China, and of its wafer-level advanced packaging systems to a leading OSAT customer in Singapore.

Introduced ACM Planetary Family™ Product Portfolio Structure. ACM launched a unified, process‑based portfolio structure, the ACM Planetary Family, organizing its products into eight distinct families aligned with key semiconductor manufacturing steps, collectively referred to as the Eight Planets series.

Sale of Shares of ACM Shanghai. On February 6, 2026, ACM completed the sale of approximately 4.8 million shares of ACM Shanghai, at a price of RMB160.00 per share (approximately $23.05 per share based on the exchange rate in effect on the date of the sale), generating approximately $110 million in gross proceeds and approximately $86 million net of taxes.

ACM Shanghai Proposed H share listing in Hong Kong. On April 17, 2026, ACM Shanghai, announced a proposed issuance of overseas listed H shares and an application for a secondary listing on the Hong Kong Stock Exchange. The initiative is intended to strengthen ACM Shanghai's capital base, enhance competitiveness, attract and retain talent, and further expand its international market presence.

First Quarter 2026 Financial Summary

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

Revenue was $231.3 million, up 34.2%, reflecting growth from ECP (front-end and packaging), furnace and other technologies, and advanced packaging (excluding ECP), services & spares.

Gross margin was 46.4% versus 47.9%. Non-GAAP gross margin, which excludes stock-based compensation, was 46.5% versus 48.2%. 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 $71.1 million, an increase of 25.2%. Operating expenses as a percentage of revenue decreased to 30.7% from 32.9%. Non-GAAP operating expenses, which exclude the effect of stock-based compensation, were $65.8 million, up 38.5%. Non-GAAP operating expenses as a percentage of revenue increased to 28.4% from 27.6%.

Operating income was $36.2 million, up 40.3% compared to $25.8 million. Operating margin was 15.6% compared to 15.0%. Non-GAAP operating income, which excludes the effect of stock-based compensation, was $41.8 million, up 17.4% compared to $35.6 million. Non-GAAP operating margin, which excludes stock-based compensation, was 18.1% compared to 20.7%.

Unrealized loss on short-term investments was $1.4 million, compared to an unrealized loss of $1.1 million. Unrealized loss reflects the change in market value of the investments by ACM Shanghai. The value is marked-to-market quarterly and is excluded in the non-GAAP financial metrics.

Income tax expense was $3.8 million, compared to $2.2 million.

Net income attributable to ACM Research, Inc. was $17.3 million, compared to $20.4 million. Non-GAAP net income attributable to ACM Research, Inc., which excludes the effect of stock-based compensation and unrealized loss on short-term investments, was $24.3 million, compared to $31.3 million.

Net income per diluted share attributable to ACM Research, Inc. was $0.24, compared to $0.30. Non-GAAP net income per diluted share, which excludes the effect of stock-based compensation and unrealized loss on short-term investments, was $0.34, compared to $0.46.

Cash and cash equivalents, plus restricted cash and short-term time deposits were $1.25 billion at March 31, 2026, compared to $1.13 billion at December 31, 2025. Net cash, which excludes short-term and long-term borrowings, was $924.2 million at March 31, 2026, versus $844.5 million at December 31, 2025.

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.
