Merger Yields World’s Largest Agency

$25 Billion In Annual Revenue

Omnicom has announced that it is acquiring rival holding company IPG, creating the world’s largest advertising group with more than 100,000 employees and some $25 billion in annual revenue. Omnicom owns ad agencies BBDO, DDB, TBWA, Goodby Silverstein & Partners and more, while IPG’s creative agencies include McCann, FCB, Deutsch, The Martin Agency, and MullenLowe, among others. Combined, the new Omnicom will have six global creative agency networks and a handful of regional shops.

“Through this combination, we are poised to accelerate innovation and harness the significant opportunities created by new technologies in this era of exponential change,” said John Wren, chairman and CEO of Omnicom, in a press statement. Unstated is that the deal is driven by ongoing disruption in  the advertising industry, as digital ads have trumped analog advertising channels and tech giants like Meta and Alphabet have moved into the territory once dominated by traditional agencies.

The acquisition, subject to regulatory and shareholder approvals, is expected to close in the second half of 2025. While the scale of the companies will be huge, some are skeptical as to whether the move will address client needs and demands.
