Nearly a year after first announcing the deal, Omnicom has completed its acquisition of The Interpublic Group of Companies following receipt of all necessary regulatory approvals and satisfaction of the other closing conditions.
Omnicom’s portfolio spans media agencies such as OMD and PHD, along with creative networks including DDB, BBDO, and TBWA. IPG’s roster includes FCB, MullenLowe, Initiative, and UM.
Together, the merged company will also hold significant PR strength, with firms such as Weber Shandwick, Golin, FleishmanHillard, Ketchum, and Porter Novelli.
Details on how the two holding companies’ brands will be structured going forward have not yet been announced.
“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.”
As previously announced, John Wren will remain Chairman and CEO, Phil Angelastro will continue as EVP and CFO, and Philippe Krakowsky and Daryl Simm will serve as Co-Presidents and COOs. Krakowsky, 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.
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.
