NEW YORK, USA – Omnicom today announced the successful completion of its acquisition of The Interpublic Group of Companies, Inc. following receipt of all necessary regulatory approvals and satisfaction of the other closing conditions. The combination creates the world’s leading marketing and sales company built for intelligent growth in the next era.
The new Omnicom unites the industry’s most comprehensive and connected portfolio of capabilities, all powered by Omni, its advanced intelligence platform. It reimagines how data, creativity, and technology combine with exceptional talent to help clients address their most critical growth priorities.
“This is a defining moment for our company and our industry,” said John Wren, Chairman and CEO of Omnicom. “With the completion of the deal, Omnicom is setting a new standard for modern marketing and sales leadership — creating stronger brands, delivering superior business outcomes, and driving sustainable growth. We’re excited about this next chapter. I want to thank our people, clients, and shareholders for the trust they have placed in us.”
Under the terms of the agreement, Interpublic shareholders received 0.344 Omnicom shares for each share of Interpublic common stock they owned. Legacy Omnicom shareholders own approximately 60.6% of the combined company and legacy Interpublic shareholders own approximately 39.4%, on a fully diluted basis. The combined company, with a pro forma combined revenue in excess of $25 billion, will trade under the OMC ticker symbol on the New York Stock Exchange.
As previously announced, John remains Chairman & CEO, Phil Angelastro remains EVP & CFO, and Philippe Krakowsky and Daryl Simm serve as Co-Presidents and COOs. Philippe, Patrick Moore and E. Lee Wyatt Jr. have also joined the Omnicom Board of Directors. The company’s full leadership team will be announced on December 1, 2025.
Omnicom’s $13.5 billion acquisition of IPG resets the global advertising landscape, putting the world’s largest agency group in play and raising expectations for more connected, accountable client solutions. With expanded strength in data, media, and technology, the combined company sets a new competitive baseline that others will need to meet. Holding companies are now being pushed to function as cohesive technology-driven networks, signaling a fresh wave of consolidation and a sharper, more modern definition of what full-service means today.
