ACM Research's 'big year' arrives: panel-level plating orders and a 105% order surge flip the growth narrative

After a 2025 of cleaning softness and shipment declines, June-quarter orders doubled as ACM validated its five-year panel-level plating bet.

From shipment trough to order inflection

A year ago, ACM Research was explaining away a nasty slide: cleaning revenue was declining YoY, full-year shipments were set to fall for the first time in years, and an inventory write-down had dragged margins below its own target band. CFO Mark McKechnie admitted on the November 2025 call that “the full year would be down year-on-year, and that is different than what we had expected.” — Mark McKechnie, CFO · 2025-11-05 The June 2026 quarter is the sharp rebuttal. Revenue hit $292.9M, up 36% YoY, shipments matched at 36% — and the most telling number of all: production orders rose 105% in the first half. Management raised the low end of the full-year guide to a $1.125B–$1.175B range ($25–30% growth) and reiterated that shipments would outpace revenue. The catch-up is driven by exactly the products that were missing last year: SPM single-wafer tools (a third of the cleaning market ACM had barely touched) and the electroplating franchise, where the 2,000th chamber shipped in the quarter — a cadence of 500 (2022) → 1,500 (2025) → 2,000 (2026). Underneath it all, the economics changed: larger chip size and rising interconnect layer counts add copper steps, and high-bandwidth memory stacking multiplies them further.

The panel bet lands a first-mover order

The headline event of the quarter is panel-level plating. David Wang announced two orders — a production tool for a Mainland China customer and an evaluation system for a new customer in Asia — for horizontal plating of glass/silicon panels:

I'm pleased to announce that we have received order from 2 advanced packaging customers for our panel-level horizontal plating tool addressing both 510 x 515-millimeter and 310 x 310-millimeter panel size... We believe ACM will be among the first company to deliver horizontal panel level plating system to multiple customers across multiple regions.
David Wang, Chief Executive Officer · 2026-08-07

This validates a five-year bet ACM made when it "predicted a shift from wafer level to panel-level packaging more than 5 years ago." On the February call, Wang had staked the claim that “We are the first one in the world so far doing horizontal plating” — David Wang, CEO · 2026-02-26 — a position he argues is the key differentiator for the square-format, large-chip size future of AI packaging. The broad order book growth is encouraging, but it is this PLP proof-of-order that moves the stock narrative from "potential" to "validated."

Riding the AI wave, with China as the engine

The 105% order surge is broad-based, but the structural driver is the China WFE thesis. Citing a third-party Frost & Sullivan report, management sees the Mainland China market exceeding $50B in 2025 and growing past $80B by 2029. The bull case is that ACM can outgrow China WFE on the strength of new products (SPM, furnace, PECVD, Track) coming out of evaluation. Wang framed it bluntly in Q&A: cleaning now consumes 5–7% of fab spend but is expanding, copper plating is "almost $1.5 billion already" and growing with HBM and backside power — and “this panel market also demand a lot of plating tool, too.” — David Wang, Chief Executive Officer · 2026-08-07 Global validation is starting to show too: close to a dozen tools went to Singapore in H1 (a foundry plus a packaging house), the Oregon demo center is on track, and the $150M registered direct offering in May built a ~$300M U.S. war chest. Wang framed the balance sheet as the credibility money for global customers: “Obviously, with this cash preparation, it show our determination, also our confidence... our long-term goal is still $1.5 billion for the revenue outside China.” — David Wang, Chief Executive Officer · 2026-08-07

Execution risk in Q3–Q4

The setup is the best in two years, but management is guiding to a back-half-heavy 57–58% of revenue, and component shortages — a sector tape theme — could dent the shipment beat. Wang acknowledged delivery lead times are stretching: “there's a little bit constraint for supply there” — David Wang, Chief Executive Officer · 2026-08-07 — mitigated by deliberate raw-material stockpiling. Gross margin held at 46.0% with the 42–48% target range restated. The financial context is a company spending into the opportunity: R&D rose 33% YoY to 13.9% of sales in Q2, guided to 16–18% for the year, and the balance sheet is loaded for the build — net cash is above $1B even as free cash flow runs negative in growth mode (Q2 FCF was −$6.4M, with CapEx guided to ~$175M). The near-term risk is real — new Track platform and PECVD revenue only kicks in after year-end qualification — but the order book is the first hard evidence that the multi-product, global story ACM has been selling for five years is finally converting into backlog, and soon into revenue.
