Triata Capital Ltd disclosed a substantial addition of 413,000 shares in ACM during Q3, bringing its total holding to 2.0 million shares valued at approximately $78.4 million at quarter-end. This single position now represents 9.15% of the fund’s U.S. equity portfolio, making ACM its fourth-largest holding. Triata’s overall U.S. equity assets under management stood at $856.8 million across 15 reportable positions as of September 30. The move underscores the fund’s conviction in a continued upswing for specialized semiconductor equipment, particularly wet cleaning and electrochemical plating tools where ACM has demonstrated market leadership.

In Q3, ACM delivered revenue of $269 million, up 32% year-over-year, driven by robust demand for single-wafer cleaning, electrochemical plating, and advanced packaging solutions. Operating income reached nearly $29 million despite gross margins contracting to 42% from over 50% in the prior year, a shift attributed to product mix and investment in capacity expansion rather than a drop in demand. The company closed the quarter with more than $1.1 billion in cash and deposits on the balance sheet, following a $623 million capital raise by its Shanghai subsidiary on the STAR Market.

ACM has scheduled the release of its preliminary revenue range for fiscal year 2025 along with its initial 2026 revenue outlook on January 22, 2026, before U.S. markets open. The company will also participate virtually in the 28th Annual Needham Growth Conference on January 15, hosting one-on-one meetings with investors. This guidance event will provide critical benchmarks for assessing demand trends across wafer and panel processing segments, and help investors gauge the trajectory of the semiconductor equipment cycle in the year ahead.
