Omnicom Group: A global leader in marketing communications, offering services across advertising, media, CRM, public relations, and healthcare. Interpublic Group (IPG): One of the world’s largest advertising holding companies, with a portfolio of creative, media, and marketing agencies.

Omnicom will acquire Interpublic in a stock-for-stock transaction. Post-closing, Omnicom and Interpublic shareholders will own 60.6% and 39.4%, respectively, of the combined entity. This creates a behemoth that offers end-to-end services for brands. This acquisition likely will lead to mergers and acquisitions in 2025 by competitors such as WPP, Publicis and Dentsu. Interestingly in the conference call discussing the transaction the presentation describes a advertising platform that encapsulates behavior,identity, and transactions in one business. Sounds familiar - hello Meta and Google.
