RILEY RICHARD T 4

What Happened
Richard T. Riley, a director of Dorman Products (DORM), had 33 shares withheld by the company to satisfy tax withholding obligations upon the vesting of restricted stock units (RSUs). The shares were valued at $116.16 each, for a total withholding value of $3,833. This withholding is treated as a disposition under Section 16 but is a routine tax-related transaction rather than an open-market sale.

Context
Tax-withholding dispositions on RSU vesting are common and do not necessarily indicate any change in the insider’s view of the company—unlike open-market purchases, they are routine administrative actions. Because this was a withholding to cover taxes (not a sale into the market), it’s primarily a payroll/tax event rather than an investment decision.
