U.S. Semiconductor Equipment Executive Sells Shares Worth Millions After RSU Vesting

In March and April, Teradyne, Inc. (NYSE: TER) executives and directors disclosed that, under pre-established SEC Rule 10b5-1 trading plans and their compensation structures, they either sold small amounts of stock or acquired deferred stock units (DSUs). On March 5, insider Mercedes Johnson sold approximately $187,000 (about KRW 240 million) worth of shares while still retaining several thousand shares. Regan Mills, president of the Products Test Division, recognized restricted stock unit vesting, satisfied the related tax withholding, and sold shares under a 10b5-1 plan on April 1 and 2, liquidating roughly $142,000 (about KRW 190 million) in equity, yet he continues to hold stakes worth several million dollars (tens of billions of KRW). Independent director Peter Hürbeck converted part of his quarterly cash retainer into DSUs, increasing his derivative equity through a deferred-compensation mechanism rather than an open-market transaction.

In its Q4 2025 earnings release, Teradyne reported revenues of $1.08 billion, exceeding market expectations. Fueled by a surge in AI semiconductor test demand, the company’s stock has climbed over 60% year-to-date in 2026, touching 52-week highs and drawing near all-time record prices.

Headquartered in North Reading, Massachusetts, Teradyne is a leading global provider of automated test equipment and industrial and collaborative robots for semiconductor and electronics applications. The company has been growing its robotics segment—led by subsidiaries such as Universal Robots—and plans to open a robotics operations hub in Metro Detroit, Michigan, in 2026. These initiatives position Teradyne to directly benefit from expanded manufacturing and automation investments across North America.
