2. How Does it Work?

• A lawsuit is initiated by one or more investors, called the “lead plaintiffs,” on behalf of a larger group of investors, or the “class”.

• The “class period” is defined as the specific timeframe during which the alleged fraudulent activity took place. Only those who bought or sold the security during this period are eligible to participate.

• A lead plaintiff is appointed to represent the class. Under the Private Securities Litigation Reform Act (PSLRA), the court will typically appoint the investor with the largest financial interest in the outcome of the case.

• The case is litigated, which may include a lengthy discovery phase for gathering evidence.

• The case can be settled or go to trial. Most class actions are resolved through settlements, which can include cash or stock paid into a common fund for the class. The lead plaintiff and class counsel approve any settlement before it is finalized.

3. What Do the Plaintiffs Have to Prove in the WPP class action lawsuit?

To succeed in a federal securities fraud class action, plaintiffs must prove several elements:

• Material misstatement or omission: The company made a false or misleading statement or failed to disclose a material fact.

• Scienter: The defendant acted with an intent to deceive, manipulate, or defraud.

• Reliance: The plaintiff relied on the misstatement or omission when buying or selling the security. For publicly traded securities, this can be proven through the “fraud-on-the-market” theory, which presumes the market price reflects all public, material information.

• Economic loss: The plaintiff suffered a financial loss.

• Loss causation: The company’s misstatement or omission directly caused the plaintiff’s loss, often demonstrated by a stock price drop after the truth is revealed in a “corrective disclosure”

6. What Are the Allegations in the WPP class action lawsuit?

WPP brands itself as a creative transformation company that provides communications, experience, commerce, and technology services.

• The WPP class action lawsuit alleges that defendants throughout the Class Period created the false impression that they possessed reliable information pertaining to WPP’s projected revenue outlook and anticipated growth while also minimizing risk from seasonality and macroeconomic fluctuations.

• In truth, according to the complaint, WPP’s optimistic reports of its potential to achieve new client bid wins and retain its existing clientele fell short of reality as WPP’s media arm was not equipped to compete effectively and had begun to lose market share to its competitors.

• The WPP class action lawsuit further alleges that on July 9, 2025, WPP published a trading update for the first half of 2025, alerting investors that WPP had allegedly “seen a deterioration in performance as Q2 has progressed,” attributing the deterioration to both “continued macro uncertainty weighing on client spend and weaker net new business than originally anticipated,” at least in part due to “some distraction to the business” as a result of the continued restructuring of WPP Media a.k.a. GroupM.

• The complaint also alleges that in a same-day press release, WPP further announced that CEO, defendant Mark Read, “will retire from the Board and as CEO on 31 December 2025.”

• On this news, the price of WPP stock fell more than 18%, according to the complaint.
