WPP plc (NYSE: WPP)
WPP and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws.
On July 9, 2025, the Company published a trading update for the first half of 2025, disclosing that it had allegedly “seen a deterioration in performance as Q2 has progressed” due to both “continued macro uncertainty weighing on client spend and weaker net new business than originally anticipated,” as well as “some distraction to the business” as a result of the continued restructuring of WPP Media a.k.a. GroupM. The Company further disclosed that its CEO “will retire from the Board and as CEO on 31 December 2025.”
On this news, the price of WPP’s shares fell from a closing price of $35.82 per share on July 8, 2025 to $29.34 per share on July 9, 2025, a decline of about 18.1% in the span of just a single day.
The first-filed case is Marty v. WPP plc, 25-cv-08365. A subsequent case, Teamsters Local 456 Annuity Fund v. WPP plc, 25-cv-09930, expanded the class period.
