DoubleVerify (DV) CEO Mark Zagorski Exercises Awards, Sells Shares

What Happened
Mark Zagorski, CEO of DoubleVerify (DV), had multiple restricted/performance stock units convert into common shares on September 15, 2026. A total of 60,819 shares were issued to him via conversion/exercise (derivative transactions, code M) at a $0 exercise price. To satisfy tax withholding obligations (code F), 31,051 of those shares were withheld/treated as disposed at $13.50 each, generating proceeds/withholding value of about $419,190. No cash exercise price was paid — these were award settlements and associated tax-withholdings rather than open-market purchases.

Context
These transactions reflect awards vesting/settling (RSUs/PSUs converting one-for-one into common stock) with shares withheld to cover tax obligations — a routine, non-open-market settlement that is common for executives receiving equity compensation. Codes: M = exercise/conversion of derivative (award vest/settle), F = payment of exercise price or tax liability (share withholding). This is not an open-market sale by the executive for investment reasons, but rather internal settlement and tax withholding tied to vested awards.
