APP CLASS ACTION NOTICE: Glancy Prongay & Murray LLP Files Securities Fraud Lawsuit On Behalf Of AppLovin Corporation Investors

Glancy Prongay & Murray LLP (“GPM”) announces that it has filed a class action lawsuit in the United States District Court for the Northern District of California, captioned Brownback v. AppLovin Corporation, et al., Case No. 25-cv-02772, on behalf of persons and entities that purchased or otherwise acquired AppLovin Corporation (“AppLovin” or the “Company”) (NASDAQ: APP) securities between May 10, 2023 and February 25, 2025, inclusive (the “Class Period”). Plaintiff pursues claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”).

Investors are hereby notified that they have until May 5, 2025 to move the Court to serve as lead plaintiff in this action.

What Happened?

On February 26, 2025, before the market opened, Culper Research published a report alleging among other things, that AppLovin’s app segment relies on the “systematic exploitation of app permissions” to “illicitly inflate the Company’s mobile gaming results.” Culper Research further alleged AppLovin’s e-commerce program is a “rigged game” which relies on “steal[ing] attribution” for advertising from Meta to bolster the Company’s results.

Also on February 26, 2025, Fuzzy Panda Research published a report which further detailed the manner in which AppLovin’s e-commerce rigged results by “reverse engineer[ing] Meta’s targeting methods” in order to “steal” referral credits for targeting advertisers. Fuzzy Panda Research further detailed the manner in which the Company’s “impossibly high CTRs (click-thru rates) of 30-40%, 10x the industry norms” are the product of what industry experts can only describe as “Ad Fraud.”

On this news, the Company’s share price fell $46.06, or 12.2%, to close at $331.00 per share on February 26, 2025, on unusually heavy trading volume.

What Is The Lawsuit About?

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that AppLovin’s app segment relied on the systematic exploitation of fraudulent advertising practices including ‘clickjacking’ and ‘click spoofing’; (2) that AppLovin’s advertising and e-commerce program relied on intercepting and appropriating advertising attribution credit; (3) that AppLovin employed a backdoor installation scheme to force unwanted apps on customers; (4) that as a result of the foregoing, AppLovin’s revenue was falsely inflated; and (5) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

If you purchased or otherwise acquired AppLovin securities during the Class Period, you may move the Court no later than May 5, 2025 to ask the Court to appoint you as lead plaintiff.
