What Happened
Shelagh Glaser, a director of PubMatic, was granted 15,811 restricted stock units (RSUs) on May 30, 2025. The RSUs were awarded with a $0 purchase price (derivative award) and represent a contingent right to receive one share of PubMatic Class A common stock per RSU upon settlement.

Key Details

• Transaction date: 2025-05-30; Type: Award/Grant (code A); Amount: 15,811 RSUs; Price: $0.00.
• These RSUs are derivatives that convert to Class A common stock upon settlement; no immediate cash changed hands.
• Vesting: RSUs vest in full on the earliest of (a) first anniversary of grant, (b) immediately prior to the Company’s 2026 annual meeting, (c) Reporting Person’s death or disability, or (d) a change in control.
• Deferral: Ms. Glaser elected to defer settlement until the earliest of (i) third anniversary of the grant, (ii) death/disability, (iii) change in control, or (iv) separation of service.
• RSUs do not expire; they either vest or are canceled prior to vesting.
• Shares owned after the transaction: not specified in the Form 4.
• Filing timeliness: The Form 4 was filed on 2026-04-14 for a 2025-05-30 grant — this is a late filing (delayed public disclosure).

Context
This was a compensation award (not an open-market purchase or sale). RSUs are a common form of equity compensation for directors and become actual shares only upon vesting/settlement; because Ms. Glaser elected to defer settlement, she will not receive stock immediately unless a listed vesting/settlement event occurs. The late filing means the market received delayed disclosure of this insider grant.
