The Allegations: Robbins LLP is Investigating Allegations that PubMatic, Inc. (PUBM) Misled Investors Regarding its Business Prospects

According to the complaint, during the class period, defendants failed to disclose (1) that a top DSP buyer was shifting a significant number of clients to a new platform which evaluated inventory differently, and (2) that, as a result, PubMatic was seeing a reduction in ad spend and revenue from this top DSP buyer.

The complaint alleges that on August 11, 2025, PubMatic released its second quarter 2025 financial results, noting that the Company’s outlook reflects “a reduction in ad spend from one of [its] top DSP partners.” The Company’s Chief Executive Officer, Rajeev Goel, further revealed that a “top DSP buyer” had “shifted a significant number of clients to a new platform that evaluates inventory differently” causing significant headwinds. Goel stated, in response to the inventory valuation change, the Company would “need to do a better job . . . to prioritize across all the hundreds of billions of daily ad impressions that we have, which subset of those impressions that we send to this DSP.” On this news, PubMatic’s stock price fell $2.23, or 21.1%, to close at $8.34 per share on August 12, 2025.
