The company’s gross margin climbed to 47.6%, exceeding its typical range, reflecting a favorable product mix, improved pricing, and beneficial RMB/USD currency movements.
While ECP, furnace, and other technologies saw a temporary 7% decline due to quarterly fluctuations, they posted strong growth for the first half and are expanding their customer base. Advanced packaging revenue also advanced, with ACMR positioning itself for further upside as AI and high-bandwidth memory trends drive packaging innovation. Operating expenses increased as ACMR invested in R&D, sales, and international expansion, but operating margin still improved to 22.4%.
- Cleaning Segment Outperformance: Cleaning tools, now covering nearly 90% of process steps, drove the bulk of growth and margin improvement.
- International Evaluation Pipeline: Tools under evaluation in the US and Europe are set to convert to revenue in late 2023 or early 2024.
- Inventory Remains Elevated: Finished goods tied up in customer evaluations weigh on working capital, but normalization is expected as supply chains ease.
ACMR’s performance is increasingly tied to China’s domestic manufacturing ambitions, but management is also laying groundwork for global diversification and next-generation product cycles.
Executive Commentary
"We achieved record revenue and EPS as our operating and industrial supply chain largely returned to a new normal following several years of COVID-related disruption. This result was driven by strong, mature node spending by our China customer, market share gain, and underpenetration of a new product, a new customer."
David Wang, CEO
"Gross margin was 47.6%, up from 42.4%. This exceeded our normal expected range of 40% to 45%. The increase in gross margin was primarily due to a favorable product mix, improved gross margins for specific product lines, and a favorable impact from fluctuations in the RMB to US dollar exchange rate."

Strategic Positioning
1. China Market Penetration and Mature Node Tailwind
ACMR is capitalizing on a strategic shift in China’s semiconductor investment toward mature nodes (28nm and above), driven by both domestic policy and EV adoption. The company’s cleaning and plating tools are now deployed at nearly all major Chinese fabs, with tier-two and tier-three customers becoming an increasing revenue source. Management expects this trend to persist as China accelerates self-sufficiency efforts.
2. Product Portfolio Diversification
Recent launches in semi-critical cleaning, bevel etcher, high-temperature furnace, and supercritical CO2 drying have expanded ACMR’s addressable market. The company now claims coverage of nearly 90% of cleaning process steps, positioning it as a one-stop solution provider for both mature and advanced nodes. Proprietary track and PECVD platforms are in customer evaluation, targeting large memory and logic opportunities for 2024 and beyond.
3. International Expansion and Customer Evaluation
ACMR is investing in facilities and service teams in Korea, the US, and Europe, aiming to convert evaluation tool placements into recurring revenue. The company’s dual R&D and manufacturing approach in China and Korea is designed to enhance flexibility and deepen relationships with global leaders like SK Hynix, while the US and European pipeline is expected to yield initial revenue in the next cycle.
4. Advanced Packaging and AI-Driven Demand
ACMR’s advanced packaging suite, including copper plating and wet etch tools, is well aligned with industry shifts toward 2.5D/3D integration and high-bandwidth memory for AI and generative AI applications. Management sees this as a structural tailwind, with active engagement across both China and international top-tier customers.
5. Capital Allocation and Operational Scale-Up
With $100 million in planned 2023 capex, ACMR is scaling its Lingang R&D and production center, expanding in Korea, and building out US demo and service capacity. The company is also deploying a dividend from its Shanghai subsidiary to fund sales, marketing, and further R&D, signaling a commitment to reinvestment and global reach.
Key Considerations
ACMR’s Q2 results underscore its ability to leverage secular trends in China while laying the foundation for global diversification and next-gen product cycles. The quarter’s context is defined by a blend of operational normalization, strategic customer wins, and product innovation, but also by persistent supply chain and order visibility challenges.
Key Considerations:
- Customer Base Broadening: Significant revenue growth is now coming from emerging tier-two and tier-three Chinese fabs, reducing reliance on a handful of large customers.
- Product Cycle Timing: Evaluation tools in the US and Europe are not expected to drive meaningful revenue until late 2023 or 2024, creating a lag in global diversification benefits.
- Inventory and Working Capital: Elevated inventory levels, especially finished goods awaiting customer acceptance, may constrain cash flow until conversion accelerates.
- Margin Volatility: While Q2 gross margin benefited from mix and FX, management maintains a cautious 40%–45% range due to product and regional variability.
- Wide Guidance Reflects Visibility Limits: Management’s broad revenue guidance band is a direct response to customer order timing, supply chain fluidity, and ongoing trade policy uncertainty.
Risks
Visibility remains limited due to ongoing supply chain constraints, customer order timing, and international trade policy impacts. ACMR’s heavy exposure to the China market heightens risk from potential regulatory or geopolitical shifts, while the timing of international revenue conversion is uncertain. Elevated inventory and a wide guidance range also signal execution and forecasting challenges, with margin sustainability dependent on mix and currency factors that may not persist.
