OMNICOM GROUP INC. vs WPP plc, two Advertising stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Omnicom and WPP are two of the largest advertising-agency holding companies, and both are working through a soft, depressed period. Omnicom is barely profitable this year, a 0.63% return on equity, while WPP is loss-making at a negative 6.2%, though both throw off free cash, Omnicom a strong 13.68% yield and WPP 4.61%. Omnicom pays a 3.97% dividend. Neither carries a clean earnings multiple. Omnicom runs almost no debt and WPP is debt-free on this measure. The pair prices two ad-agency giants through an industry downturn: Omnicom generates far more free cash and holds a small profit, WPP is deeper in the red, and both trade on a recovery in agency spending.
