Wendell P. Weeks, Chairman, CEO and President of Corning Inc. (GLW), has maintained a consistently one-sided insider trading pattern over the past year, with all 52 reported transactions involving sales or compensation-related events and zero open-market purchases. The most recent activity, filed June 9, 2026, shows a $18.6 million open-market sale of GLW shares alongside a $2.7 million option exercise, continuing a trend of monetizing equity rather than accumulating it. That sale follows a $21.4 million disposition on February 26, 2026, also paired with an option exercise worth $3.7 million. Across all filings, Weeks has sold approximately $50.4 million in stock, with no corresponding buy-side conviction trades recorded.
The transaction mix is dominated by GLW, though a single Amazon (AMZN) option exercise on February 15, 2026, appears in the record. Most of the GLW activity consists of routine corporate actions: grants (code A), option exercises (code M), shares withheld for taxes (code F), and gifts (code G) with no cash value. The two most recent open-market sales, however, represent genuine discretionary dispositions totaling roughly $40 million. The largest single event was a $27.9 million tax-withholding transaction on April 15, 2026, which is automatic and not a market decision. The overall pattern shows a seller with no recent purchases, consistent with a long-tenured executive diversifying concentrated equity holdings rather than signaling fresh conviction in the stock.
