ICON (ICLR) Director John Climax Sells Shares to Cover Taxes After RSU Vest

What Happened
John Climax, a director of ICON plc (ICLR), had restricted share units vest and convert into 1,732 ordinary shares on Aug 10, 2026. Following that conversion, he sold 841 shares in open-market transactions on Aug 11 for total gross proceeds of approximately $138,168 to satisfy tax-withholding obligations. The filing also shows a grant of 1,324 restricted share units on Aug 10, 2026 that are scheduled to vest on May 22, 2027. These transactions appear to be routine (sale to cover taxes) rather than a discretionary sell signal.
