Last earnings call, Aug 7, 2026 AI summary
- What they said
- ACM Research reported Q2 2026 revenue and shipments up 36% year-over-year, with ECP and advanced packaging categories each growing over 150% YoY. The company secured panel-level horizontal plating orders from two customers across multiple regions. Net cash exceeded $1 billion globally, including ~$300M in the US following a $150M registered direct offering. H1 2026 orders surged 105% year-over-year across all product categories.
- Guidance
- Management reaffirmed 2026 growth targets, expecting shipments to grow faster than revenue across all categories. Beyond 2026, newer platforms including Track, PECVD, and horizontal panel-level plating are expected to transition from evaluation to commercialization, driving production orders.
- Risks flagged
- Key risks mentioned: component shortages and longer lead times (supply chain constraints), potential component price increases (though management currently does not expect material margin impact), timing risk around shipment qualification and revenue recognition (some tools may ship later than planned), competitive dynamics (PECVD competition, qualification hurdles for new products), and uncertainty on Hong Kong listing timing or disclosures.
