Zagorski Mark 4

What Happened

• Mark Zagorski, CEO of DoubleVerify (DV), received equity awards and multiple tranches of restricted/performance stock units vested or converted in mid‑March. The filing shows a March 12, 2026 grant of 275,000 restricted stock units (RSUs), with 8.33% of that grant vesting/settling on March 15, 2026. Several other previously granted RSU/PSU tranches also converted into common stock on or about March 15.
• To cover tax withholding obligations associated with those vestings/conversions, 57,173 shares were withheld (code F) at a reported withholding price of $10.21 per share, totaling approximately $583,737. There are no reported open‑market sales for cash proceeds — the disposals in the filing are tax withholding related.

Key Details

• Transaction dates: grant on 2026‑03‑12; vesting/conversion and tax withholding occurred on/around 2026‑03‑15 (Form 4 filed 2026‑03‑16).

Context

• Transaction codes: M = exercise/conversion of derivative (here, conversion/settlement of RSUs/PSUs into common stock); F = shares withheld to satisfy tax withholding (a “sell‑to‑cover” administrative action). This is routine vesting/settlement activity rather than an open‑market sale or purchase signaling a personal trade decision.
• For retail investors: vesting and withholding are normal compensation events. The key actionable datapoint here is the tax withholding amount and that the company awarded 275,000 RSUs (with a standard quarterly vesting schedule).
