Stockholder Proposals to be Presented at Next Annual Meeting

Our bylaws provide that for stockholder nominations to our Board of Directors or other proposals to be considered at an annual meeting of stockholders, the stockholder must give timely notice thereof in writing to the Corporate Secretary at PubMatic, Inc., 601 Marshall St., Redwood City, California 94063, Attention: Corporate Secretary.

To be timely for our 2026 annual meeting of stockholders (the “2026 Annual Meeting”), a stockholder’s notice must be delivered to or mailed and received by our Corporate Secretary at our principal executive offices not earlier than 5:00 p.m. Eastern Time on January 30, 2026 and not later than 5:00 p.m. Eastern Time on March 1, 2026. A stockholder’s notice to the Corporate Secretary must set forth, as to each matter the stockholder proposes to bring before the 2026 Annual Meeting, the information required by applicable law and our bylaws.

Stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act and intended to be presented at our 2026 Annual Meeting must be received by us not later than December 18, 2025 in order to be considered for inclusion in our proxy materials for that meeting.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires that our directors, executive officers, and persons who beneficially own more than 10% of our common stock, file reports on Forms 3, 4 and 5 with the SEC concerning their ownership of, and transactions in, our common stock.

Based solely upon a review of the reports filed with the SEC, or written representations from reporting persons, we believe that during the fiscal year ended December 31, 2024, all Section 16(a) filing requirements were satisfied on a timely basis, with the exception of Rajeev Goel, Amar Goel, Mukul Kumar, and Paulina Klimenko, who failed to timely file a Form 4 by January 30, 2024 with respect to two transactions for each of those individuals. Additionally, Rajeev Goel failed to timely file a Form 5 by June 3, 2022 with respect to four transactions.
