On May 28, Acm Research rose 5.35% in regular trading, trading at $93.25/share, with trading volume of $81.75 million, extending its recent strong upward trajectory.

On the news front, the company recently unveiled a major breakthrough in its high-temperature SPM cleaning technology at SPCC2026. The solution achieves particle control of fewer than 15 particles at the 15nm standard, significantly outperforming mainstream alternatives, with plans to further reduce to 13nm. This advancement is expected to support yield improvements for GAA logic devices and DRAM/HBM chips, with over 20 units scheduled for delivery in the current year.

Meanwhile, the company reported Q1 new order growth of 65% year-over-year, maintaining full-year revenue guidance. The average delivery cycle is approximately six months, positioning much of the new order intake for near-term revenue conversion. The combination of technological differentiation and robust demand continues to fuel investor optimism.
