The Thesis
ACM Research is a semiconductor equipment company that makes specialized cleaning tools used to build advanced computer chips. The company generated $0.90 billion in revenue for the full 2025 fiscal year, representing 15% growth over the prior year. The recent launch of the ACM Planetary Family marks the structural shift from a niche cleaning tool provider into a multi product platform across furnace, plating, and chemical vapor deposition technologies.
The bet here comes down to four specific things.
In our view, there is meaningful upside still ahead, driven by how fast the company is expanding its product portfolio into new parts of the chipmaking process. We think the market is underestimating the value of the company’s massive net cash position and its ability to gain share from larger global rivals. The case for owning this only gets stronger if the new product families show accelerating adoption in the next few quarters. For long term investors, this is one of the more direct ways to own the growth of advanced chip manufacturing.
Numbers at a Glance
What does it do?
ACM Research is a growth business that earns money by designing and selling high performance equipment used to clean and process silicon wafers during chip manufacturing. The process of making a computer chip involves hundreds of steps, and any tiny particle of dust can ruin the whole wafer. ACM Research sells tools that use proprietary megasonic waves to shake off these particles without damaging the delicate chip structures. The company makes money through the initial sale of these multi million dollar machines and then collects recurring revenue from providing spare parts and maintenance services.
Where does revenue come from?
The vast majority of revenue comes from the sale of single wafer cleaning and advanced packaging equipment. These systems include the Ultra C series for cleaning and ECP tools for electroplating. While the company is headquartered in California, almost all of its physical manufacturing and customer base is currently located in China.
Revenue Breakdown
Revenue by Geography
Who are its customers?
ACM Research serves leading semiconductor manufacturers and outsourced assembly firms including a major global packaging manufacturer and a top tier OSAT customer in Singapore. While the company does not disclose a total customer count, it reported $231.3 million in revenue in the most recent quarter. Shipments grew to $240.7 million in early 2026, which represents the total value of equipment sent to customers for testing and final purchase. Management highlighted that growth is increasingly coming from customers outside of mainland China as they ramp up production in Singapore and the United States.
What gives it staying power?
The company’s staying power comes from its proprietary SAPS and TEBO cleaning technologies that competitors cannot easily replicate. These methods allow for uniform cleaning of 3D chip structures that are extremely fragile. Because chipmakers design their entire production lines around these specific tools, the switching costs for a customer to change suppliers are very high.
Where is it headed?
The company is making a major strategic bet on expanding its product lineup to cover eight distinct families of semiconductor equipment. This "Planetary Family" strategy aims to turn the company into a one stop shop for multiple steps of the manufacturing process. If this works, it will triple the total addressable market for the company’s tools and reduce its dependence on the cleaning segment alone.
ACM Research is seeing strong revenue acceleration, with Q1 2026 sales jumping 34% to $231 million. This growth is outpacing the 15% revenue increase seen during the full 2025 fiscal year. The acceleration suggests that the company is successfully gaining market share as customers adopt its new product categories.
Cash quality is currently under pressure as the company builds inventory and invests in new manufacturing facilities. Free cash flow was negative $0.07 billion in 2025 despite the company being profitable on an earnings basis. This gap is common for growing equipment makers that must spend heavily on parts and factories before they can ship and collect payment for their machines.
The balance sheet is exceptionally strong with a net cash position of $924.2 million as of March 2026. This massive cash pile provides a significant safety net and allows the company to fund its global expansion without needing to take on expensive debt. Total cash and restricted cash reached $1.25 billion following a successful share sale by the company's Shanghai subsidiary.
ACM Research is a financially robust growth business with a massive cash cushion that is currently sacrificing short term cash flow for long term scale.
Shipments reached $240.7 million in the first quarter of 2026, representing a massive 54% increase over the prior year. This figure is a leading indicator because shipments today typically turn into recognized revenue in three to nine months. The growth is coming from both the core cleaning business and newer plating and packaging tools.
Gross margins fell to 46.4% in the latest quarter compared to 47.9% in the prior year. The decline is driven by a shift in product mix as the company sells more of its newer, lower margin tools to gain a foothold with new customers. If margins continue to trend lower, it could signal that the company is losing pricing power or facing tougher competition.
The semiconductor equipment market is roughly $100 billion today and is on track to exceed $150 billion by 2028 as global chip demand scales. Pricing power is structural because chipmakers value yield and reliability over the initial cost of a machine. ACM Research stands as a fast growing challenger in this market, currently holding a small but expanding share of the global cleaning segment. While the giants dominate high volume production, the company's specialized technology has allowed it to carve out a profitable and defensible niche.
The semiconductor equipment market is concentrated and rationally structured, with a few large players controlling the majority of the market. High barriers to entry exist because new tools require years of joint development and testing with chip manufacturers.
Screen Holdings(7735.T) is the most dangerous threat because it holds the largest market share in cleaning and has deep financial resources to defend its position. Tokyo Electron(8035.T) and Lam Research(LRCX) threaten the company by offering bundled deals that make it difficult for a single product supplier to break into new factories.
ACM Research is clearly gaining share, evidenced by its 34% revenue growth which is significantly higher than the overall industry growth rate. The company is successfully displacing incumbents in the high growth advanced packaging and cleaning segments.
The primary source of protection is the company’s proprietary IP, specifically its SAPS and TEBO cleaning technologies. These patented methods use megasonic waves to clean wafers more effectively than traditional spraying methods used by rivals. The company’s 46% gross margin proves that customers are willing to pay a premium for this performance edge.
The combination of 46% gross margins and a 54% jump in shipments proves that the technology advantage is real and translating into market demand. However, the TTM ROIC of 4.4% suggests that the business is still in a heavy investment phase and has not yet reached the efficiency of its mature peers. The numbers suggest a real technological moat that is still being scaled into a broader business advantage.
The moat is strengthening as the company expands its "Planetary Family" of products to increase customer switching costs.
Revenue grew 34% in Q1 2026 while shipments increased 54% year-over-year.
Generated $110 million from a subsidiary share sale to fund global expansion.
Founder CEO Hui Wang remains the principal leader and visionary for the company.
Capital Allocation Track Record
Hui Wang has delivered exceptional growth by focusing on high-end technology that solves specific production problems for chipmakers. The decision to build a massive cash cushion of $924 million through smart subsidiary financing significantly de-risks the company's aggressive global expansion plans. Management has shown a consistent ability to meet or exceed its revenue targets while successfully navigating a complex international trade environment.
