WPP Investors Urged to Seek Lead Role in Securities Suit as Dec. 8 Deadline Nears

Overview

• Multiple shareholder-rights firms, including Glancy Prongay & Murray, DJS Law Group, The Schall Law Firm and The Law Offices of Frank R. Cruz, issued new notices on Nov. 20–21.
• The putative class covers purchases from Feb. 27, 2025 through July 8, 2025, with a Dec. 8, 2025 deadline to seek appointment as lead plaintiff.
• The complaint asserts violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 based on alleged misstatements about revenue forecasting, new client wins and retention.
• Filings also allege weaknesses at WPP’s media arm (formerly GroupM), including loss of market share and distraction from restructuring efforts.
• WPP’s July 9, 2025 update reported deteriorating Q2 performance, after which the stock fell about 18% to $29.34, a move plaintiffs cite as evidence of investor harm; the case remains un-certified.
