## Overview

ACM Research, Inc. designs and supplies capital equipment used in semiconductor manufacturing, with a focus on wet-cleaning and other front-end process tools that help chipmakers improve yield at advanced process nodes. The company also develops and sells advanced packaging tools used by wafer assembly and packaging customers. Although headquartered in Fremont, California, substantially all operations and manufacturing are conducted through its majority-owned subsidiary ACM Research (Shanghai), Inc., with a manufacturing center in Shanghai. ACM sells globally via direct sales teams and field application engineers, using a “demo-to-sales” approach that places evaluation tools at selected customers to support qualification and repeat orders.

## Customers

ACM Research sells primarily to semiconductor manufacturers and packaging houses that purchase wafer fab equipment for foundry/logic, memory (including DRAM and 3D NAND), and advanced packaging/wafer processing lines. Customers buy ACM tools to improve yield and process performance as device scaling, 3D architectures, and new materials tighten tolerances in yield-critical steps. The company’s sales model emphasizes qualification and repeatability: it places “first tools” for evaluation and then converts to repeat orders once process and contractual requirements are met. Revenue is concentrated among a small number of large chipmakers, with four customers accounting for 52.2% of revenue in 2025 (same in 2024), reflecting the industry’s concentrated buyer base.

- **Foundry / Logic / Other** (primary) — Buy wet-cleaning and front-end tools to support advanced nodes and improve yield in high-volume foundry/logic production.
- **Memory (DRAM and 3D NAND)** (primary) — Purchase cleaning and process tools tuned for 3D architectures and tight defectivity requirements in memory fabs.
- **Advanced Packaging / Wafer Processing** (secondary) — Buy advanced packaging tools to support wafer assembly and packaging process steps as packaging complexity increases.

- Foundry and logic fabs buying yield-critical front-end process tools
- Memory manufacturers (DRAM, 3D NAND) needing advanced cleaning capability
- Advanced packaging and wafer processing customers buying packaging tools
- Large, concentrated customer base drives high account-level dependency
- Customers often require tool qualification/acceptance before full rollout
- Repeat orders are important after successful first-tool evaluations

## Geography

ACM Research is incorporated in the United States and runs corporate functions from Fremont, California, but its manufacturing center has been in Shanghai since 2006 and substantially all operations are located in mainland China through ACM Shanghai. Substantially all sales in 2025–2023 were to customers outside the United States, reflecting the concentration of semiconductor manufacturing capacity in Asia. The company maintains direct sales teams in mainland China, the United States, Southeast Asia, and Europe, supported by field application engineers co-located with customers for qualification and ramp phases. This footprint creates meaningful exposure to cross-border trade rules, local regulatory requirements, and the practical challenges of enforcing U.S. legal judgments against assets and personnel located in mainland China.

- Corporate HQ in Fremont, California; strategy/finance/marketing centralized there
- Manufacturing center in Shanghai since 2006; operations largely in mainland China
- Substantially all sales are outside the United States (2025–2023)
- Direct sales presence in mainland China, U.S., Southeast Asia, and Europe
- Field application engineers support on-site qualification and fab expansions
- Cross-border compliance (import laws, taxes) is a recurring operating constraint

## Strategy

ACM Research’s strategy centers on expanding adoption of its wet-cleaning and front-end tools in yield-critical steps as semiconductor manufacturing complexity increases with scaling, 3D architectures, and advanced packaging. Commercially, the company relies on a “demo-to-sales” motion that seeds evaluation tools at selected customers and aims to convert them into repeat orders after qualification and acceptance. Operationally, it must scale manufacturing output and supply chain responsiveness during industry upturns while avoiding excess inventory and cost absorption issues if demand softens. The company also manages a dual-market structure with ACM Shanghai listed on the STAR Market, which can support local positioning and funding but adds disclosure, governance, and investor-communication complexity.

- Drive penetration of yield-critical cleaning steps at advanced process nodes
- Convert first-tool evaluations into repeat orders via demo-to-sales motion
- Expand beyond mainland China by supporting initiatives in SE Asia and Europe
- Scale production capacity in upcycles without creating excess inventory risk
- Leverage ACM Shanghai STAR listing while managing dual disclosure regimes

## Risks

ACM Research faces customer concentration risk because a small number of large chipmakers account for a substantial portion of revenue, and the total addressable customer set is limited. Its operating footprint is heavily weighted to mainland China (manufacturing and substantial assets), creating exposure to geopolitical friction, trade and import compliance, tax and repatriation constraints, and challenges enforcing U.S. judgments against overseas assets and personnel. Semiconductor capital equipment demand is cyclical; misjudging the timing of upturns/downturns can lead to lost share (if capacity is insufficient) or margin pressure and inventory write-downs (if demand weakens). The company also highlights cybersecurity and intellectual property protection risks, as tool differentiation depends on proprietary technologies (e.g., SAPS, TEBO, Tahoe, ECP, furnace) and customer trust in secure operations.

- **Customer concentration and limited number of potential customers** [high] — A small set of chipmakers drive demand; four customers were 52.2% of 2025 revenue.
- **Mainland China operating and asset concentration** [high] — Manufacturing and substantially all operations are in mainland China, raising regulatory, tax, and enforceability risks.
- **Cyclicality and capacity/inventory planning in semiconductor equipment** [high] — Upturns require rapid output increases; downturns can create excess inventory and price discounting.
- **Cybersecurity and intellectual property protection** [medium] — Threats include IP theft, fraud, extortion, and privacy/security law violations; differentiation depends on proprietary technologies.
- **Dual listing/disclosure complexity (Nasdaq vs STAR Market)** [medium] — Different accounting/disclosure regimes can lead to differing information releases and potential volatility/arbitrage.

- High customer concentration; loss of a major account can hit revenue materially
- Semiconductor capex cyclicality drives volatile demand and utilization planning
- Mainland China operating footprint increases geopolitical/regulatory exposure
- Import/export and compliance constraints can disrupt shipments and servicing
- IP theft or leakage could erode differentiation of proprietary tool platforms
- Cybersecurity incidents could disrupt operations and compromise sensitive data
- Dual U.S./STAR disclosure regimes may create investor confusion and volatility

## Accounting

Revenue recognition is sensitive to tool delivery and customer acceptance provisions: the company notes that some delivered tools are subject to customer acceptance or subsequent discretionary purchase commitment, which can shift revenue timing between periods. Inventory accounting is judgmental because many work-in-process and finished goods units are configured for specific customer orders; provisions for slow-moving inventory can materially affect gross margin and working capital. The consolidated financials include non-controlling interests because ACM Research owns less than 100% of ACM Shanghai following share sales and equity issuances, affecting net income attributable to ACM Research shareholders. Government subsidies are recognized differently depending on their nature (e.g., depreciable-asset subsidies credited over useful lives versus VAT reduction subsidies recognized in the period received), which can affect comparability of operating results across periods.

- **Revenue recognition and customer acceptance** — Quarter-to-quarter revenue volatility and backlog/acceptance sensitivity
- **Inventory valuation and provisions** — Gross margin, working capital, and potential write-downs
- **Non-controlling interests (ACM Shanghai minority holders)** — Net income attributable to ACM Research differs from consolidated net income
- **Government subsidies recognition** — Other income/operating income comparability across periods

- Revenue timing depends on delivery vs customer acceptance of tools
- Contract terms can defer revenue until contractual obligations are met
- Inventory provisions for slow-moving/configured tools affect margin and WC
- Non-controlling interests from ACM Shanghai ownership reduce attributable NI
- Government subsidies: asset-related over life vs VAT-related in period received
- Allowance for credit losses impacts receivables quality and earnings volatility
