Sotheara Cheav, serving as Senior Vice President of Manufacturing for ACM Research (Shanghai), Inc., a subsidiary of ACM Research, Inc. (NASDAQ:ACMR), has executed a significant series of equity transactions. According to a recent filing with the U.S. Securities and Exchange Commission, Cheav sold shares valued at approximately $1.59 million and exercised stock options worth roughly $260,437. These activities took place on June 4 and 5, 2026, marking a notable liquidity event for the executive.
The sales involved a total of 18,750 shares of Class A Common Stock. The transactions were executed at prices ranging between $81.73 and $85.77 per share. Crucially, these sales were carried out under a Rule 10b5-1 trading plan. Cheav adopted this pre-arranged trading framework on March 5, 2026, which allows for the execution of trades at predetermined times regardless of subsequent market movements or non-public information.
Concurrently with the sales, Cheav exercised stock options for an identical number of shares, totaling 18,750 shares of Class A Common Stock. The exercise price for these options was $13.89 per share. The filing confirms that these options were fully vested and exercisable at the time of the transactions, indicating that the executive had met all necessary criteria to convert these options into common stock.
This insider activity unfolds against a complex backdrop for ACM Research. The company recently reported first-quarter 2026 earnings that surpassed market expectations. Earnings per share came in at $0.34, exceeding the forecasted $0.28. Revenue also outperformed projections, reaching $231.3 million against an anticipated $217.77 million. Despite these positive financial results, ACM Research announced a registered direct offering of 2.9 million shares of Class A common stock. This offering is priced at $52.00 per share and is structured under a Securities Purchase Agreement with U.S. institutional investors managed by Tekne Capital Management, LLC. The offering is expected to close soon, pending customary closing conditions, which introduces potential dilution dynamics for existing shareholders.
Market performance data indicates that ACMR shares have delivered a remarkable 209% return over the past year. However, the stock has recently pulled back to $76.29. According to InvestingPro analysis, the stock currently appears overvalued relative to its Fair Value.
