[Form 4] PubMatic, Inc. Insider Trading Activity

Rhea-AI Filing Summary

PubMatic, Inc. (PUBM) – Form 4 insider filing (07/03/2025)

General Counsel & Secretary Andrew Woods reported routine equity activity tied to restricted stock unit (RSU) vesting:

• 11,496 Class A shares were acquired on 07/01/2025 through automatic RSU settlement (transaction code M) at $0 cost.
• 4,084 shares were immediately sold on 07/02/2025 at a weighted-average $12.5633 to cover statutory tax-withholding obligations via a “sell-to-cover” arrangement.
• Post-transactions, Woods’ direct ownership stands at 44,130 Class A shares; he also retains unvested RSUs representing the right to acquire an additional 100,000-plus shares across four award buckets (20,195; 7,505; 33,967; 39,333 units).

The filing reflects scheduled vesting under previously granted equity awards rather than discretionary buying or selling. No new option grants, open-market purchases, or substantive disposals were disclosed.

Positive

• Net increase of 7,412 directly held shares after tax-related sale indicates insider maintains and grows equity stake.
• Large unvested RSU balance (≈100k shares) keeps management incentives aligned with long-term shareholder value.

Negative

• 4,084 shares sold (though for withholding) could be perceived as minor insider selling signal.

Insights

Senior Securities Analyst

TL;DR: Routine RSU vesting; minimal sell-to-cover; neutral impact.

Woods’ Form 4 shows standard quarterly RSU vesting. The 4,084-share sale is tax-driven and represents <0.1% of PubMatic’s average daily volume, signalling no shift in sentiment. Retained ownership rises by roughly 7,400 net shares, and sizable unvested RSU inventory aligns incentives with shareholders. Absent discretionary selling or new equity grants, the filing is considered operationally neutral and offers limited investment signal.
