Overview

A class action lawsuit has been filed against WPP PLC (“WPP” or the “Company”) and certain of the Company’s former senior executive officers alleging violations of the federal securities laws. The Company’s common stock traded on the New York Stock Exchange (the “NYSE”) under the symbol “WPP.”

The WPP class action lawsuit was brought on behalf of all persons and entities who purchased or otherwise acquired WPP common stock between February 27, 2025, to July 8, 2025, both dates inclusive, (the “Class Period”).

WPP is a global communications company that offers advertising, media management, consultancy, public relations, as well as branding and identity services worldwide. WPP Media, formerly GroupM, media arm of WPP, which uses data analytics and newer AI technologies to create, plan, and buy integrated media campaigns for its global clients.

The lawsuit alleges that WPP and its executives misled investors about the company’s financial outlook and the true condition of its media division leading up to the 2025 fiscal year. According to the allegations, defendants repeatedly expressed confidence in WPP’s ongoing efforts to simplify and revitalize its media operations, asserting that new business wins and continued sales to existing clients would offset the loss of certain accounts. They also emphasized what they described as “cautious” guidance that supposedly accounted for broad macroeconomic uncertainty.

The lawsuit contends that these statements were materially false and misleading because WPP’s media arm was, in reality, struggling to compete effectively amid worsening macroeconomic conditions and was losing significant market share to competitors. By omitting these material facts, defendants allegedly caused WPP’s stock to trade at artificially inflated prices, misleading investors about the company’s operational stability and growth potential.

On July 9, 2025, WPP issued a trading update for the first half of 2025, revealing that the company had “seen a deterioration in performance as Q2 has progressed.” WPP attributed the decline to “continued macro uncertainty weighing on client spend” and “weaker net new business than originally anticipated,” partly due to “some distraction to the business” caused by the ongoing restructuring of its media division, GroupM. Following this disclosure, WPP’s stock price fell sharply—from $35.82 per share on July 8, 2025, to $29.34 per share on July 9, 2025, representing a one-day decline of approximately 18.1%.

The lawsuit alleges that, as a result of defendants’ misleading statements and omissions, investors suffered significant financial losses when the truth about WPP’s business challenges was revealed to the market.
