ACM Research, Inc. Class A (ACMR)

Over the past six months, ACM Research's stock has experienced significant volatility. The stock has seen a substantial increase, with a 91.0% gain over the past six months and a 196.5% gain over the past year. The stock fell 16.7% on February 26, 2026, after the company reported its Q4 2025 results due to a decline in net income and gross margin. ACM Research reported strong Q1 2026 results with revenue of $231.3 million, up 34.2% year-over-year, surpassing analyst expectations, but non-GAAP diluted EPS declined. The company announced multiple advanced packaging equipment orders and completed shipments of its Ultra C vac-p panel-level advanced packaging vacuum cleaning system and wafer-level advanced packaging systems. Analyst ratings have varied, with some initiating coverage with a "Buy" rating while others downgraded the stock to "Hold" or "Sell".

Seasonality plays an increasingly important role in the market for chip manufacturing tools, impacting ACM Research's product demand. Historically, the period from November through February has been weaker due to capital equipment for chips needed for December holidays typically being in the supply chain by October, and chip makers in Asia often delay capital acquisition plans until after the Chinese New Year. The timing of new product releases also influences demand.
