What Happened

• Steven J. Mougis, Global Chief Communications Officer of DoubleVerify (DV), received a grant of 112,500 restricted stock units (RSUs) on March 12, 2026. On March 15, 2026 multiple RSU/PSU vesting events and derivative conversions occurred, resulting in the conversion/acquisition of 47,749 underlying shares (conversion price $0).
• To satisfy tax withholding obligations, 17,220 shares were withheld/sold at $10.21 per share, generating approximately $175,816 in cash proceeds. After withholding, Mougis received a net ~30,529 shares. These disposals (code F) are tax withholdings, not open-market investment sales.

Context

• These transactions are routine vesting/conversion and tax-withholding events (derivative conversions and RSU/PSU settlements), not open-market purchases or discretionary sales. For RSUs/PSUs the shares convert one-for-one into common stock and a portion is commonly withheld to cover taxes; such withholdings should not be read as directional insider trading.
