ACM Research: Panel-Level Plating Orders Arrive as Order Book Doubles and China WFE Estimate Jumps to $50 Billion
Q2 2026 earnings call, August 7, 2026
ACM Research delivered a quarter that validated a bet the company placed more than five years ago, and management used the call to show investors that the wager is now paying off in the form of actual purchase orders. Revenue came in at $292.9 million, up 36% year-over-year, with shipments of $281.5 million, also up 36%. The bigger signal, however, was in the order book: first-half 2026 orders rose 105% year-over-year, a figure CEO David Wang described as evidence of "real demand and also a large backlog."
Panel-Level Plating Moves From Thesis to Orders
The single most important disclosure on the call was that ACM has now received actual orders for its horizontal panel-level plating tool, addressing both 510mm x 515mm and 310mm x 310mm panel formats. One order is a production order from an existing Mainland China customer, and the second is an evaluation system for a new customer in Asia. Wang called this "an important milestone for what we believe could become a significant long-term growth opportunity," and management believes ACM will be among the first companies to deliver horizontal panel-level plating systems to multiple customers across multiple regions. This matters because panel-level packaging is increasingly viewed across the industry as the likely solution for next-generation AI chips, HBM stacks, and large reticle-exceeding designs, where wafer-level packaging is hitting practical limits. Wang noted the company is positioned for both the larger Intel-championed panel format and the TSMC-led approach, calling the panel opportunity "very, very hard" competitively but one where ACM has prepared for both camps. Management was unable to give a firm timeline for conversion of the evaluation system into a repeat order, but framed the next 6 to 12 months as the window where visibility should improve.
China WFE Market Estimate Revised Sharply Higher
ACM raised its serviceable addressable market assumptions this quarter using updated data from Frost & Sullivan's Global and China Semiconductor Equipment Market Research report. The China wafer fab equipment market is now estimated to exceed $50 billion in 2025, growing to more than $80 billion by 2029, while the global WFE market is pegged above $140 billion in 2025 and above $200 billion by 2029. That translated into a $1 billion increase to ACM's own global SAM estimate, now around $22 billion. Importantly, the company left its long-term revenue target of $4 billion unchanged, still split roughly $2.5 billion from Mainland China and $1.5 billion from the global market outside China, implying management sees the higher market ceiling as room to grow into rather than an immediate reason to raise targets.
SPM Cleaning Tool Ramp Is the Next Product Cycle to Watch
Cleaning revenue actually declined 14% year-over-year to $133 million, or 45% of sales, a figure that on its face looks concerning given cleaning has historically been ACM's core franchise. Management was direct about the reason: the single-wafer SPM tool, which addresses roughly one-third of the total cleaning market, has generated almost no revenue to date despite the company having shipped a handful of units in the first half and targeting more than 20 shipments by year-end. CFO Mark McKechnie noted that "SPM will be reflected first in our shipments, followed by revenue contribution in later quarters," meaning the cleaning segment's current softness is a timing issue tied to customer qualification cycles rather than share loss. Investors should watch for cleaning revenue to inflect as repeat orders begin flowing once qualifications complete.
ECP and Advanced Packaging Are Now Driving the Business
The growth story this quarter was unambiguously plating and packaging. ECP, furnace and other technology revenue grew 168% year-over-year to $128.5 million, 44% of sales, while advanced packaging revenue (excluding ECP) grew 153% to $31.4 million, or 10.7% of sales. During the quarter ACM shipped its 2,000th electroplating chamber, up from 1,500 in 2025 and 500 in 2022, a cadence that shows the installed base is scaling quickly. Wang noted management projected copper plating would become a $1.5 billion market roughly four to five years ago when "nobody really believed it," and that estimate has now essentially been realized, with additional tailwinds coming from backside power delivery and HBM DRAM stacking driving more copper process steps per device.
Customer Concentration Is Improving
ACM's customer base broadened meaningfully. In the first half of 2026, only one customer represented more than 10% of revenue, at 12.7%, compared with three 10%-plus customers representing nearly 50% of revenue in the first half of 2025. McKechnie called the reduced concentration "positive as it represents a broadening of our customer base," a data point that should ease investor concerns about reliance on any single Chinese fab customer.
Balance Sheet Built as War Chest for Global Expansion
ACM ended the quarter with $1.36 billion in gross cash and $1.0 billion in net cash, including roughly $300 million held on the U.S. balance sheet following a $150 million registered direct offering completed in May. Management was explicit that this capital is earmarked to fund expansion in the U.S., Taiwan, Singapore and Europe, and to give global customers confidence that ACM can support production orders once they materialize. McKechnie said there are no near-term plans to sell down the company's stake in ACM Shanghai to fund this expansion. The company's Oregon facility is on track to open a demo center later this year, and management reiterated a target of more than 20 tools installed outside Mainland China across roughly 10 customers in 5 countries by year-end.
New Platforms Approaching Commercialization
Management provided updates on three newer platforms it expects to transition from evaluation to commercial orders. The PECVD platform, built on a proprietary one-chamber, three-track architecture, shipped a second tool to a new customer in the first quarter, with qualification anticipated by year-end. The track platform is progressing through customer evaluation with production qualification also expected by year-end. Wang said the company anticipates becoming a leading local supplier for track systems in China, while acknowledging PECVD is "quite competitive" but that ACM's platform addresses "certain special big market requirements."
Guidance Raised Modestly, Supply Constraints Flagged
ACM raised the low end of its full-year 2026 revenue guidance to a range of $1.125 billion to $1.175 billion, up from a prior range of $1.08 billion to $1.175 billion, implying 25% to 30% year-over-year growth. Management flagged component shortages as a mild risk to shipment timing, noting delivery lead times that were previously four months have in some cases stretched to six months, though pricing from key suppliers has not increased materially. The company said it had stocked up on raw materials in anticipation of a heavy 2026, which is helping mitigate the impact, and reiterated its 42% to 48% long-term gross margin target with no expected pressure from input costs. Full-year capital expenditure guidance was maintained at approximately $175 million, with Lingang's second production building set to open later this year, bringing combined capacity across both buildings to support up to $3 billion in annual output.
