Outlook

ACM is providing its revenue guidance range of $650 million to $725 million for fiscal year 2024. 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 2023 were $597 million, versus $539 million in 2022. Total shipments in the fourth quarter of 2023 were $140 million, versus $197 million in the fourth quarter of 2022. Total shipments include deliveries for revenue in the quarter and deliveries of first tool systems awaiting customer acceptance for potential revenue in future quarters.
• Received Qualification for SAPS Tool from US Manufacturer. ACM announced that its SAPS cleaning tool has been qualified for revenue from a large US manufacturer in the fourth quarter of 2023. An Ultra C b backside cleaning and bevel etch tool is expected to be delivered to this customer in the second quarter of 2024.
• Proposed Private Offering. ACM’s principal operating subsidiary, ACM Research (Shanghai), Inc. (“ACM Shanghai”) (SSEC: 688082.SS), announced that it intends to offer up to 43.6 million of its ordinary shares, subject to market conditions, the approval of ACM Shanghai’s shareholders, completion of the review process by the Shanghai Stock Exchange, completion of the registration process by the China Securities Regulatory Commission, and other factors, in a private offering to qualified buyers, in compliance with the requirements of the China Securities Regulatory Commission (the “Private Offering”). The gross proceeds to ACM Shanghai of the proposed Private Offering of up to RMB 4.5 billion ($625 million) are intended to be used for research and development, capital expenditures and working capital. If consummated in full, we estimate that ACM’s equity interest in ACM Shanghai would decline from 82.1% to approximately 74.6%.
  

Full Year 2023 Financial Summary

Unless otherwise noted, the following figures refer to the full year of 2023 and comparisons are with the full year of 2022.

• Revenue was $557.7 million, up 43.4%, reflecting higher sales of single wafer cleaning, Tahoe and semi-critical cleaning equipment, electro-chemical plating (“ECP”) (front-end and packaging), furnace and other technologies, and Advance packaging (excluding ECP), and services and spares. We attribute the revenue growth to continued investments in mature process nodes by current and new mainland China-based customers amidst an ongoing target to achieve a greater share of the global semiconductor market, incremental contribution from newly introduced tools, and additional penetration of our product portfolio across our customer base.
• Gross margin was 49.5%, up from 47.2%. Non-GAAP gross margin, which excludes stock-based compensation, was 49.8%, up from 47.4%. Gross margin exceeded the range of 40% to 45% reflected in ACM’s long-term business model. The increase in gross margin was due to a favorable product mix, improved gross margins for specific product lines, and a favorable impact from currency fluctuations. 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 $180.4 million, an increase of 44.8%. Non-GAAP operating expenses, which exclude the effect of stock-based compensation, were $154.4 million, up 31.6%. Operating expenses as a percent of revenue increased to 32.3% from 32.0%. Non-GAAP operating expenses as a percent of revenue decreased to 27.7% from 30.2%.
• Operating income was $95.8 million, up from $59.0 million. Non-GAAP operating income, which excludes the effect of stock-based compensation, was $123.2 million, up from $66.8 million.
• Unrealized loss on short-term investments was $2.7 million. The loss reflects the change in market value of the investments by ACM Shanghai in short-term investments. The value is marked-to-market quarterly and is excluded in the non-GAAP financial metrics.
• Realized gain from sale of short-term investments was $9.0 million versus $1.1 million.
• Income tax expense was $19.4 million versus $16.8 million. As a result of a change in Section 174 of the U.S. Internal Revenue Code of 1986, as amended, that became effective on January 1, 2022, ACM’s effective tax rate remains elevated, due primarily to the requirement to capitalize and amortize previously deductible research and experimental expenses.
• Net income attributable to ACM Research, Inc. was $77.3 million, compared to net income of $39.3 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 $107.4 million, compared to non-GAAP net income of $54.8 million.
• Net income per diluted share attributable to ACM Research, Inc. was $1.16, compared to $0.59. Non-GAAP net income per diluted share, which excludes the effect of stock-based compensation and unrealized loss on short-term investments, was $1.63, compared to $0.83.
