Lee Kang Jyh

Lee Kang Jyh, CEO of Photronics, Inc. (PLAB), has demonstrated a consistent pattern of selling company shares over the past two years, with no recent purchases recorded in SEC filings. Since January 2025, Lee has executed 21 sales totaling approximately $7.03 million, with transactions ranging from $203,000 to $770,600. The most recent disposals occurred in March 2026, including a $204,000 sale on March 26 and a $390,000 transaction three days prior. Earlier in 2026, Lee conducted a concentrated series of sales between January 2 and January 16, unloading shares worth over $2.3 million across eight separate filings. The transactions show a clear divestment trend, with only two small acquisitions—$53,750 and $227,000—recorded alongside sales in December 2025 and March 2026, likely representing option exercises. All activity has been confined to PLAB, where Lee holds an executive position. The selling pace intensified in early 2026, with multiple disposals per week during January, before tapering slightly in March. Notably, the largest single sale occurred on December 12, 2025, when Lee liquidated $770,600 worth of shares. The absence of any buys since 2025 suggests a sustained reduction in Lee's stake in the semiconductor photomask manufacturer.
