Exhibit 99.01

ACM Research Reports Fourth Quarter and Fiscal Year 2024 Results

FREMONT, Calif., February 26, 2025 (Globe Newswire) – ACM Research, Inc. (“ACM”) (NASDAQ: ACMR), a leading supplier of wafer processing solutions for semiconductor and advanced packaging applications, today reported financial results for its fourth quarter and fiscal year ended December 31, 2024.

“2024 was a year of strong execution for ACM. We expanded our product portfolio and broadened the addressable markets we serve,” said ACM’s President and Chief Executive Officer, Dr. David Wang. “We grew revenue by 40% and total shipments by 63%. We gained additional market share by capitalizing on product cycles and deepening engagements with key customers, demonstrating the strength of our multi-product portfolio. Our operating profit increased by 57.6%, and we generated  $152 million in cash flow from operations.”

Dr. Wang continued, “In the fourth quarter, we achieved two major operational milestones. First, we achieved process qualification of our Thermal and Plasma-Enhanced ALD furnace tools at two semiconductor customers in mainland China. Second, we commenced initial operations at our Lingang production facility, and we are on track to transition additional capacity to Lingang as we progress through the year.”

Dr. Wang concluded, “Looking ahead to 2025, we remain focused on expanding our business with incremental revenue contribution from Tahoe, SPM, and Furnace, additional customer evaluations for both Track and PECVD, increasing localization in China, and contributions from our expanding global footprint. Regarding the addition of our subsidiaries to the U.S. Entity List, we believe the impact on the ability of ACM Research (Shanghai) to produce tools will be manageable, and that we can continue to support our global customer base.”

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. We have updated our long-term business model to a gross margin target range of 42% to 48%, versus the prior range of 40% to 45%.

Operating Highlights and Recent Announcements

•	Shipments. Total shipments in 2024 were $973 million, up 63.1%. Total shipments in the fourth quarter of 2024 were $264 million, versus $140 million in the fourth quarter of 2023. Total shipments include deliveries<br> for revenue in the quarter and deliveries of first tool systems awaiting customer acceptance for potential revenue in future quarters.
•	Thermal and Plasma-Enhanced ALD furnace tools achieved process qualification. ACM announced the achievement of process qualification of its Ultra Fn A Plasma-Enhanced Atomic Layer Deposition (PEALD) and Thermal Atomic Layer Deposition (Thermal ALD) Furnace<br> tools at two mainland China semiconductor customers.

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.

Reconciliation of GAAP to Non-GAAP Financial Measures

As described under “Use of Non-GAAP Financial Measures” above, 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, each of which excludes stock-based compensation (“SBC”) from the equivalent GAAP financial line items. In addition, non-GAAP net income attributable to ACM Research, Inc., and basic and diluted earnings per share exclude unrealized gain (loss) on short-term investments. The following tables reconcile gross margin, operating expenses, operating income, net income attributable to ACM Research, Inc., and basic and diluted earnings per share to the related non-GAAP financial measures:
