Opinion

SIDNEY HSU, Case No. 25-cv-07067-JSC

Plaintiff, ORDER RE: MOTION TO DISMISS v. Re: Dkt. No. 39 PUBMATIC, INC., RAJEEV K. GOEL, and STEVEN PANTELICK, Defendants.

Plaintiff brings this putative class action against PubMatic, Inc. (“PubMatic”) and its Chief Executive Officer Rajeev K. Goel and Chief Financial Officer Steven Pantelick (“Individual Defendants”) for making false and misleading statements. (Dkt. No. 38.)1 Pending before the Court is Defendants’ motion to dismiss. (Dkt. No. 39.) Having considered the parties’ submissions, the Court concludes oral argument is not required, see N.D. Cal. Civ. L.R. 7-1(b), VACATES the July 31, 2026 oral argument, and GRANTS Defendants’ motion to dismiss. Plaintiff’s complaint does not adequately identify the challenged statements or allege facts that support an inference as to why each challenged statement is false or misleading, and Plaintiff does not allege facts which create a strong inference of Defendants’ scienter. I. AMENDED COMPLAINT ALLEGATIONS “PubMatic is a technology company that enables real time programmatic advertising transactions for advertisers, agencies, and demand side platforms (‘DSPs’).” (Dkt. No. 38 ¶ 2.) According to PubMatic, “its integrated technology platform empowers content creators (which it refers to as ‘publishers’) across the Internet to maximize monetization of their advertising inventory” and “provides control and technology to buyers, which includes advertisers, agencies, agency trading desks, and DSPs.” (Id. ¶ 25.) On August 11, 2025, PubMatic issued a press release announcing its financial results for the fiscal quarter ended June 30, 2025, in which Mr. Pantelick stated PubMatic’s “outlook includes a reduction in ad spend from one of [its] top DSP partners.” (Id. ¶ 45.) In an earnings call that day, Mr. Goel revealed “beginning in July, we saw a headwind emerge from a top DSP buyer, which recently shifted a significant number of clients to a new platform that evaluates inventory differently.” (Id. ¶ 46.) According to Mr. Goel, PubMatic “saw this notable drop in spend in July, and then [] s[aw] that stabilize in August.” (Id.) When asked whether “the platform shift that [he was] talking about has been going on for some time,” Mr. Goel responded he could not “speak to exactly what was their timeline or all the history of changes that they made,” but PubMatic “certainly saw an uptick or significant increase of this activity from the DSP causing the drop in spend in July.” (Id. ¶ 47.) “On this news, PubMatic’s stock price fell $2.23, or 21.1%, to close at $8.34 per share on August 12, 2025.” (Id. ¶ 48.) A. False Statements and Misrepresentations In (1) a February 27, 2025 press release announcing financial results for the fiscal quarter and full year ended December 31, 2024, (id. ¶ 29); (2) a February 27, 2025 SEC Form 10-K for Fiscal Year 2024, (id. ¶¶ 30-32); (3) a May 8, 2025 press release regarding financial results for the fiscal quarter ending March 31, 2025, (id. ¶ 33); and (4) its May 8, 2025 SEC Form 10-Q disclosing financial results for the fiscal quarter ending March 31, 2025, (id. ¶¶ 34-35), PubMatic made “materially false and misleading” statements which “failed to disclose material adverse facts about the Company’s business, operations, and prospects.” (Id. ¶ 36.) “Specifically, Defendants failed to disclose to investors: (1) that a top DSP buyer was shifting a significant number of clients to a new platform which evaluated inventory differently; (2) that, as a result, PubMatic was seeing a reduction in ad spend and revenue from this top DSP buyer; and (3) that, as a result of the were materially misleading and/or lacked a reasonable basis.” (Id. ¶ 36.) The Complaint bolds and italicizes several specific statements, including: (1) February 27, 2025 press release:

Revenue growth in the year more than doubled over 2023, driven by strength in CTV, emerging revenue streams, and marquee customers choosing PubMatic to build and scale their ad business. (Id. ¶ 29.) (2) SEC Form 10-K for Fiscal Year 2024:
