Goldman Sachs initiated coverage of WPP with a sell rating Wednesday morning. The stock fell 4.5% to 265.6p in London trading within hours. Publicis Groupe and Omnicom received buy ratings in the same coverage launch, the first time Goldman's European media desk has formally ranked the three holding companies against each other since the 2023 agency sector reset.
The bank's analysts argued WPP faces structural difficulty returning to meaningful organic growth, citing client concentration in categories under secular pressure and a cost base that remains elevated relative to newer competitors. Goldman set a GBp 635 twelve-month price target on WPP, below the GBp 680 consensus. Publicis and Omnicom targets were not disclosed in the initial coverage note, but the buy ratings came with language describing both as better positioned for AI-driven workflow transformation and U.S. retail media growth. WPP generated £13.1 billion in revenue for 2024, down 2.1% organically, while Publicis posted €13.9 billion with 4.8% organic growth in the same period.
The divergence matters because family offices and endowments have been rotating out of legacy European services exposure since mid-2024, and this is the first tier-one sell-side call explicitly naming WPP as the loser in a three-horse race. Publicis has spent €1.2 billion on technology acquisitions since 2022, including Epsilon and Sapient integrations that now generate 58% of group revenue through data and digital channels. Omnicom's Omni platform, launched in September 2024, has signed 120 enterprise clients in five months, most of them consumer packaged goods and pharma accounts WPP once held. WPP's comparable offering, WPP Open, has 41 disclosed clients as of March 2025, and its AI partnership with Microsoft Azure remains pilot-stage for most network agencies. The margin gap is 320 basis points between WPP's 13.2% EBITDA margin and Publicis's 16.4%, the widest since 2019.
Allocators should track WPP's Q2 earnings call in late July for any acceleration in cost reduction beyond the £300 million program announced in February. Publicis reports Q2 in mid-July; watch for U.S. retail media revenue as a percentage of Epsilon's total, which has been running near 37% and is expected to cross 40% by year-end. Omnicom's Omni platform client count will be disclosed in the August earnings deck, and any number above 150 would confirm the platform is past proof-of-concept and into scale.
Goldman's European media team has $840 million in assets under coverage and has not issued a sell rating on a top-five holding company since 2021. The WPP call is the first since that desk was rebuilt in January 2025.
