[Form 4] PubMatic, Inc. Insider Trading Activity

Rhea-AI Filing Summary

PubMatic, Inc. (PUBM) – Form 4 insider transaction

Chairman & Chief Innovation Officer Amar K. Goel reported the automatic conversion (code M) of 12,437 Class A shares on 07/01/2025 following the vesting of several restricted-stock-unit (RSU) grants. To cover the associated tax-withholding obligations, Goel executed a "sell-to-cover" sale of 4,417 shares on 07/02/2025 at a weighted-average price of $12.56 per share (price range: $12.23-$12.71). After these transactions, the insider directly owns 20,516 Class A shares and retains sizable unvested RSU positions (aggregate lines show 5,985; 12,180; 41,687; and 45,433 units outstanding).

The filing reflects routine equity-compensation vesting and tax settlement rather than discretionary open-market selling. No new options or derivative instruments were issued, and the insider remains a significant equity holder.

Positive

• Net share increase: Insider’s direct holdings rose to approximately 20,516 shares despite tax-related sales, maintaining ownership alignment.
• Sizable unvested RSUs signal continued long-term incentive alignment and retention of key executive.

Negative

• Share sale: 4,417 shares sold at $12.56 could be viewed as slight selling pressure, though purpose is tax withholding.

Insights

Corporate Governance Expert

TL;DR: Routine RSU vesting; small tax sale, neutral impact.

The mix of code M (RSU settlement) and code S (sell-to-cover) is typical for equity-compensated executives. Goel’s net share balance rose by roughly 8,000 shares even after the tax sale, preserving alignment with outside shareholders. The transaction represents less than 0.1 % of PubMatic’s diluted share count, so market impact is negligible. Absence of discretionary selling or option exercises above market price suggests no directional signal on valuation. Overall, the filing is administrative and neutral for investors.
