ACM Research shares jumped early in trading, rising 14.0% in the pre-open session after management released second-quarter results that substantially exceeded analyst expectations on the top and bottom lines. The company reported earnings per share of $0.61, versus a consensus estimate of $0.42, and revenue of $292.92 million, topping the $269.24 million forecast.
The quarterly results reflected robust year-over-year momentum: revenue and shipments each increased 36% compared with the same period a year earlier. Within the quarter, two product groups stood out. The ECP product line expanded 168% year over year, while advanced packaging products increased 153% year over year, signaling that ACM’s portfolio is contributing beyond its traditional cleaning tools.
Operational milestones accompanied the revenue gains. ACM said it shipped its 2,000th ECP chamber during the quarter, an indicator of growing adoption of the company’s ECP technology in high-volume chip manufacturing. Management also adjusted full-year guidance by raising the lower end of its 2026 revenue forecast to a range of $1.125 billion to $1.175 billion.
Balance sheet strength was highlighted in the release: ACM ended the quarter with $1.0 billion in net cash. The combination of an outsized earnings beat, accelerating sales in higher-value product segments, a raised guidance floor and a strong cash position contributed to the sizable pre-market move in the stock.
The broader U.S. market provided a modestly favorable backdrop but did not drive the magnitude of ACM’s move. On the same trading day, the NASDAQ rose 0.6%, the S&P 500 gained 0.3%, and the Dow Jones edged up 0.1%.
Investor interest in semiconductor equipment remains elevated amid continued demand for AI-capable chips, and ACM’s China-focused exposure to advanced packaging and logic manufacturing has kept it on analysts’ radars. The company entered the results announcement with prior price target increases from Morgan Stanley and Roth Capital already supporting a constructive analyst view.
Despite the rally, ACM shares remained notably below their 52-week high of $127.19, and market participants treated the earnings release as a potential re-rating event rather than a new peak in the stock’s valuation. Taken together, the quarter’s beats on earnings and revenue, strong unit growth in targeted product lines, the guidance adjustment and the cash position provided the fundamental justification for the early session surge.
Clear summary: ACM Research reported Q2 EPS of $0.61 and revenue of $292.92 million, both beating estimates, with 36% year-over-year growth in revenue and shipments. ECP and advanced packaging sales accelerated sharply, management raised the lower end of full-year 2026 revenue guidance to $1.125 billion to $1.175 billion, and the company closed the quarter with $1.0 billion in net cash, prompting a 14.0% pre-market rise in the stock.
