Gimbel Lisa 4

What Happened

• Lisa Gimbel, PubMatic's Chief Accounting Officer, had 3,765 restricted stock units (RSUs) vest/convert into shares on May 15, 2026 (1,395 + 773 + 802 + 795 = 3,765 shares; conversion price $0.00).
• Following the vesting, 2,863 shares were sold in an open-market/block sale on May 18, 2026 at a weighted-average price of $9.89, generating proceeds of about $28,319. The sale was executed to satisfy tax-withholding obligations (a "sell-to-cover").
• Net newly acquired shares retained after the sell-to-cover were 902 shares (3,765 vested minus 2,863 sold).

Context

• These entries reflect RSU vesting and a routine sell-to-cover tax withholding, not an independent open-market purchase or a discretionary sell for investment reasons. The RSUs were converted at no cash cost and some of the resulting shares were sold immediately to pay taxes.
• Sell-to-cover transactions are common when equity awards vest and do not necessarily signal the insider’s view on the company’s stock.
