AI Semiconductor Equipment CEO Sells Millions in Shares Amid Option Exercise

On May 15, Gregory Stephen Smith, CEO of U.S. automated semiconductor test‐equipment maker Teradyne, Inc. (Nasdaq: TER), exercised all of his outstanding stock options and concurrently sold a portion of his shares, disclosing transactions totaling about $2.9 million (roughly KRW 4 billion). On the same day, board member Marilyn Matz sold a small block of shares valued at approximately $270,000 (around KRW 400 million). Then, between May 21 and 22, Shannon John Poulin, president of Teradyne’s Semiconductor Test Division, exercised stock options, sold shares, and processed share withholdings to cover taxes and the option exercise price.

All of these insider trades were executed under pre‐arranged Rule 10b5-1 trading plans.

In its Q1 2026 earnings released at the end of April, Teradyne reported record quarterly revenue of $1.282 billion and diluted earnings per share of $2.53, noting that roughly 70% of its sales were driven by AI‐related demand.

Teradyne’s share price has trended upward on expectations of growing demand for AI semiconductor testing, boosting its market capitalization to about $60 billion (around KRW 80 trillion).

Headquartered in North Reading, Massachusetts, Teradyne supplies wafer, package and system-level test solutions to leading global semiconductor firms such as Samsung Electronics, Intel and Qualcomm. Founded in 1960, the company has grown into a premier name in semiconductor test equipment and also operates a robotics business that includes collaborative robots and autonomous mobile robots.
