A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than October 20, 2025. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually litigate securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm achieved the largest ever securities class action settlement against a Chinese Company at the time. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.

DETAILS OF THE CASE: According to the lawsuit, throughout the Class Period, defendants made false and misleading statements and/or failed to disclose that: (1) a top demand side platform ("DSP") buyer was shifting a significant number of clients to a new platform which evaluated inventory differently; (2) as a result, PubMatic was seeing a reduction in ad spend and revenue from this top DSP buyer; and (3) as a result of the foregoing, defendants' positive statements about PubMatic's business, operations, and prospects were materially misleading and/or lacked a reasonable basis. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
