Brewer, Attorneys & Counselors announce industry expert in Foster v. WPP, Nick Manning, published an analysis related to the lawsuit, which is currently pending in New York Supreme Court. The analysis is available on Mr. Manning's LinkedIn.

Mr. Manning is the founder of Encyclomedia International and Non-Executive Chairman of Media Marketing Compliance (MMC), and previously served as Chief Strategy Officer at Ebiquity and co-founded Manning Gottlieb OMD.

The case (Supreme Court of the State of New York, County of New York, Index No: 659721/2025) was brought by Richard Foster, a 17-year veteran of GroupM, WPP's media buying arm. Mr. Foster served as global CEO of Motion Content Group. Mr. Foster alleges that WPP terminated his employment in retaliation for raising internal concerns about the company's handling of advertising rebates and discounts — specifically, that those amounts were not being passed along to clients, and instead constituted an undisclosed profit center he estimates at nearly $1 billion in 2024. WPP has not responded publicly to Mr. Manning's report as of this advisory.

Brewer, Attorneys & Counselors retained Mr. Manning as an expert witness on behalf of Mr. Foster. His analysis examines court documents, including materials related to an internal project referred to as "Project Claridges," which are cited in connection with the media trading practices described in Mr. Foster's internal report. The analysis also addresses the potential implications of those practices for WPP's recently announced "Elevate 28" strategy.

"Nick Manning's analysis is directed to Mr. Foster's report to those in the C-Suite — regarding WPP's media trading practices and their alleged impact on clients," said William A. Brewer III, partner at Brewer, Attorneys & Counselors and lead counsel to Mr. Foster.

"Richard Foster raised concerns internally about media trading practices, at considerable personal risk. Mr. Manning's work provides expert context to the court record," Mr. Brewer added.
