ACM Research is a technology company specializing in advanced cleaning and plating equipment for the semiconductor industry. The company leverages proprietary technologies to address the complex requirements of leading-edge chip fabrication, supporting customers worldwide in enhancing manufacturing efficiency and yield. Its competitive advantage lies in innovative solutions that enable precise wafer cleaning and plating for both 2D and 3D semiconductor devices.
Foolish Take
Adding aggressively amid a staggering stock run suggests conviction that the story is still early, as opposed to crowded. ACM Research sits in a very specific part of the semiconductor value chain where incremental process complexity drives outsized demand for specialized tools, even when headline chip spending cools.
The fundamentals back that up. In the third quarter, ACM grew revenue 32% year over year to $269 million, driven by strength in single-wafer cleaning, electrochemical plating, and advanced packaging. Gross margin fell to 42% from over 50% a year ago, but that decline reflects mix and expansion costs instead of demand erosion. Operating income still came in at nearly $29 million, and the company exited the quarter with over $1.1 billion in cash and deposits after its Shanghai subsidiary raised roughly $623 million on the STAR Market.
More broadly this fund’s top holdings skew heavily toward China-linked internet and infrastructure names, so positioning ACM as a top-five holding fits a broader bet on domestic semiconductor buildout rather than global consumer electronics cycles.
