WPP plc Faces Surge of Investor Litigation Amid Market Volatility

On Thursday, October 10 2025, the shares of WPP plc (LON:WPP), a leading global communications services group, fell 5.9 % to a trading low of GBP 345.90, the same price at which the stock closed the day. The decline reflected a broader sell‑off across the London Stock Exchange, with the FTSE 100 slipping 0.86 % to 9 427.47 points. Trading volume for the WPP shares dropped to 5,011,130, a 54 % decline from the session’s average volume of 10,990,854 shares.

The price collapse coincided with a flurry of legal and investor‑alert news that has brought renewed scrutiny to the company’s strategic direction. Multiple law firms have announced the initiation of shareholder class actions on behalf of investors who suffered substantial losses in the recent months. The filings target WPP’s perceived over‑promotion of its artificial‑intelligence‑driven media arm, an area the company has been emphasizing amid macro‑economic pressures.

  • Levi & Korsinsky, LLP opened a complaint on October 9, urging shareholders to act before a lead‑plaintiff deadline of December 8, 2025. The firm claims that purchasers of WPP common stock between February 27 and July 8, 2025 have incurred losses that warrant recovery.
  • Robbins Geller Rudman & Dowd LLP and Holzer & Holzer, LLC followed suit, each announcing class‑action lawsuits that aim to hold WPP accountable for misleading statements about its AI initiatives.
  • Levi & Korsinsky, LLP reiterated its call for investors to join the action on October 10, while Pr‑Inside and Law360 reported that the suit alleges WPP exaggerated the success of its AI‑focused strategy, potentially inflating the company’s valuation.

Market Context

WPP’s last closing price on October 8, 2025, stood at GBP 345.9, the same as the low reached on Thursday. This price represents the 52‑week low for the company, whereas its 52‑week high, recorded on December 8, 2024, reached GBP 903. The company’s market capitalization currently sits at approximately £3.89 billion, and its price‑to‑earnings ratio is 9.742, suggesting a valuation on the lower end of its historical range.
