ACMR Q4 2025: New Product Ramp Targets 25% Growth Amid Margin Headwinds
ACMR’s Q4 capped a year of double-digit growth, but operating leverage was pressured by competitive pricing and heavy R&D investment. The company’s 2026 outlook hinges on a broad new product cycle, with international expansion and advanced packaging tools set to drive the next phase. Investors should monitor gross margin recovery and execution on global customer wins as the company pursues its $4 billion revenue target.
Summary
- Product Cycle Inflection: 2026 will see a significant revenue contribution from new cleaning and advanced packaging platforms.
- Margin Compression Persists: Competitive pricing and sustained R&D investment continue to weigh on operating leverage.
- International Expansion Accelerates: Global customer wins and strategic capacity buildout position ACMR for broader market share gains.
Performance Analysis
ACMR delivered 15% full-year revenue growth, outpacing a flat China wafer fab equipment (WFE) market and underscoring the company’s resilience in a challenging environment. Core cleaning tools, which comprised 69% of total revenue, grew 8%, while advanced packaging surged 45%, now representing 8% of the business. However, gross margin fell below the long-term range, landing at 41% in Q4 and 44.5% for the year, pressured by mix shift toward lower-margin semi-critical products and elevated inventory provisions.
Operating margin contracted sharply year-over-year, as R&D intensity rose to 16% of sales and SG&A costs climbed to support global expansion. Net cash position was fortified by strategic equity sales in ACM Shanghai, providing ample funding for R&D and global capacity initiatives. Management expects gross margins to remain at the lower end of the target range in early 2026, with improvement dependent on successful ramp of new products.
- Segment Outperformance: Advanced packaging and non-cleaning categories delivered outsized growth, reflecting customer adoption of new process tools.
- Inventory Build: Finished goods and raw materials increased, reflecting proactive supply chain management and tools under customer evaluation.
- Customer Concentration: Four customers accounted for over half of 2025 revenue, a persistent dynamic in semiconductor capital equipment markets.
The company’s ability to convert technical progress into commercial wins outside China will be crucial for sustaining top-line momentum and restoring margin leverage.
Executive Commentary
"We made a lot of progress with new product platforms, and we strengthen our position in China and globally. Investment in AI and data center infrastructure is reshaping the global semiconductor demand, shifting capital toward advanced logic, memory, and advanced packaging. The industry is looking to key supplier for new technology, many of which have not yet been invented."
Dr. David Wong, CEO
"Gross margins were down 8.8 percentage points year-over-year on a quarterly basis. This was due to product mix and margin pressure concentrated in a few semi-critical products, which contributed about five points to the headwind, and a higher level of inventory provisions that contributed about four points negative impact. As David noted, we expect the lower gross margins to be temporary."

Strategic Positioning
1. New Product Ramp and Portfolio Expansion
2026 marks a pivotal product cycle for ACMR, with SPM cleaning, supercritical CO2 dry, and advanced packaging tools expected to drive incremental growth. Management highlighted proprietary nozzle and etching technologies that address high-value process steps, aiming for best-in-class performance and customer uptime. The company estimates its cleaning portfolio will cover 100% of addressable applications by year-end, positioning it for share gains as customers migrate to advanced nodes.
2. International Market Penetration
Recent wins with Singapore, North American, and global packaging customers validate ACMR’s technology outside of China. The company shipped its first single wafer cleaning tools to a Singapore foundry and secured multiple panel-level packaging orders from global players, with deliveries scheduled through 2026. Expansion into Korea, Taiwan, and the U.S. is underway, supported by a new Oregon facility for local evaluation and production, mitigating tariff risks and enhancing customer proximity.
3. Capacity and Capital Structure
Lingang production and R&D center is now the primary manufacturing hub, with capacity for up to $3 billion in annual output. The mini-line accelerates internal validation and customer collaboration, compressing R&D and qualification cycles. Proceeds from ACM Shanghai equity sales are earmarked for R&D, manufacturing expansion, and global channel development, giving ACMR flexibility to fund growth without near-term capital constraints.
4. Competitive Dynamics and IP Moat
China’s capital equipment market is seeing a surge of local entrants, but ACMR’s deep IP portfolio and differentiated technology are its main defenses. Management is confident that customer demand for world-class performance will favor ACMR’s solutions, especially as global customers face process challenges in AI and advanced packaging. The company’s ability to defend pricing and maintain margin will be tested as competition intensifies.
Key Considerations
ACMR’s 2025 performance reflects the early innings of a broader product and geographic expansion, but margin volatility and customer concentration remain central watchpoints. The company’s strategic bets on innovation and global reach are set against a backdrop of intensifying competition and shifting industry capital allocation.
Key Considerations:
- Product Mix Sensitivity: Margin recovery depends on successful ramp and commercial adoption of higher-margin new products in 2026 and beyond.
- Global Execution Risk: Expansion in the U.S., Singapore, and Taiwan requires robust local support, customer engagement, and supply chain adaptation.
- R&D and OpEx Discipline: Sustained high R&D spend is necessary for innovation, but operating leverage needs to improve as revenue scales.
- Customer Concentration: Reliance on a handful of large customers exposes ACMR to abrupt demand shifts or project delays.
Risks
Margin compression could persist if competitive pricing, especially in China, erodes the benefits of new product introductions. Customer concentration and project timing create volatility in shipments and revenue recognition. Global expansion exposes ACMR to geopolitical, regulatory, and tariff risks, particularly as it builds U.S. manufacturing and sales channels. The company’s ability to defend its IP and maintain technical leadership will be tested as new entrants target similar process segments.
Forward Outlook
For Q1 2026, ACMR expects:
- Revenue mix to be front-loaded, with Q1 contributing 18% to 20% of full-year sales
- Gross margin at the lower end of the 42% to 48% target range in H1, with improvement in H2 as new products ramp
For full-year 2026, management reiterated guidance:
- Revenue of $1.08 billion to $1.175 billion, implying 25% growth at the midpoint
Management cited several drivers for the outlook:
- Strong customer interest in new cleaning, plating, and panel-level packaging tools
