On June 23, ACM Research fell 7.73% in regular trading, trading at $99.565/share, with turnover of $38.07 million. The decline came amid a broad selloff across the semiconductor equipment sector, erasing gains the stock had posted earlier in the week.

Within the Semiconductor Equipment sector where ACM Research belongs, individual stocks declined sharply. Among peers, Applied Materials fell 7.94%, ASML Holding fell 6.52%, Lam Research fell 8.91%, KLA-Tencor fell 8.55%, and Teradyne fell 8.53%. The sector-wide weakness stands in contrast to the prior week's positive sentiment, when SEMI data showing record quarterly global semiconductor equipment shipments of $36.55 billion — a 14% year-over-year increase driven by AI-related investment — had lifted equipment names broadly.

ACM Research develops, manufactures, and sells single-wafer wet cleaning equipment for integrated chip manufacturing worldwide, with products spanning advanced cleaning, electrochemical plating, and PECVD systems serving global wafer fabrication and advanced packaging customers.
