# Sony alleges WPP ran a 'global crime scheme' in media rebate scandal Advertising giant WPP faces lawsuit over claims it improperly managed client rebates worldwide. - **Source:** [Business Insider](https://www.businessinsider.com) - **Published:** 2026-08-14 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/a9b91da3-700f-4076-8bd2-52eadfef1eb3 ## Sony's explosive allegations An independent investigation commissioned by Sony alleges WPP diverted media rebates for its own profit instead of clients. A 2025 report presented to WPP accused the company of operating a 'global crime scheme' across markets including China. The research revealed WPP used client spending to negotiate rebate deals with media owners through intermediary brokers. ## $1.5 billion in questionable profits Plaintiff and former executive Richard Foster claims GroupM improperly managed $1.5-2 billion in rebate profits over five years. In China during 2024, $110 million was reportedly returned to clients while $350 million remained in WPP's 'future utilization' pool. These funds allegedly bypassed audits and were used to subsidize ad inventory costs. ## Current legal status WPP calls the lawsuit 'baseless' and is pushing for dismissal. The company argues Foster's amended complaint aims to salvage the case. Foster counters that Sony's findings corroborate his whistleblowing and seeks $100M in damages. The ex-executive emphasizes he rejected a seven-figure silence agreement about undisclosed rebate practices. ## The ad industry's dark side Undisclosed media rebates can create legal issues, especially in markets like China that rely on broker networks. The 'principal media' model—where agencies buy discounted inventory to resell—fuels debate. Critics highlight conflict risks when agencies prioritize owned inventory over client goals. In the US, this model reportedly accounts for 5-15% of major brand activities. ## China corruption links WPP's China operations previously faced legal troubles—former GroupM China CIO Di Fei received a life sentence for bribery. Sony's claims draw support from a Chinese criminal trial and interviews with ex-executives. WPP rebranded GroupM as WPP Media last year amid these challenges, signaling strategic shifts in its troubled markets. ## Supported by internal documents Sony's allegations cite contract language, financial reports, internal emails about rebate amounts, and tracking system documentation. One slide shows WPP's 'later utilization' rebate pool, while another labels the practice a 'fraud scheme' in China and other markets. These materials reportedly came from criminal proceedings and executive interviews. ## What industry experts say Consulting firm Madison and Wall estimates principal media represents single-digit or low-double-digit percentages of US agency activities. Critics warn agencies may steer clients toward owned inventory rather than optimal options. Foster's attorney stresses every agency must answer: 'Are your profits derived from loyal client service?' ## Potential global repercussions The lawsuit poses major risks for WPP, which manages tens of billions in ad spend. Claims of prioritizing profits over client interests could intensify transparency demands industry-wide. Loss of trust from key partners like Sony may impact WPP's global operations and stock value long-term, especially if similar practices emerge elsewhere. ## Sources covering this story - https://www.businessinsider.com/lawsuit-alleges-sony-investigation-into-wpp-rebates-2026-8 — --- _Summary written by Brifing from the original reporting.
