Omnicom acquires Interpublic Group: 'Now is the perfect time'

Omnicom has confirmed its acquisition of The Interpublic Group of Companies, Inc.

On Monday, the board of directors for the holding companies unanimously approved a definitive agreement pursuant to which Omnicom will acquire Interpublic in a stock-for-stock transaction.

The acquisition of Interpublic will make the combined holding companies the industry’s deepest bench of marketing talent, and the broadest and most innovative services and products.

Agencies under Interpublic include Initiative, Kinesso, Magna, McCann, Mediahub, R/GA and UM. These add to Omnicom's current stable of Hearts & Science, OMD, PHD, BBDO, TBWA and Flywheel.

The new Omnicom will have over 100,000 expert practitioners. The company will deliver end-to-end services across media, precision marketing, CRM, data, digital commerce, advertising, healthcare, public relations and branding.

The executive leadership of the business sees John Wren remain chairman and CEO of Omnicom. Phil Angelastro will remain EVP & CFO of Omnicom. Philippe Krakowsky and Daryl Simm will serve as co-presidents and COOs of Omnicom.

Krakowsky will also be co-chair of the Integration Committee post-merger. Three current members of the Interpublic Board of Directors, including Krakowsky, will be welcomed to the Omnicom board of directors.

"This strategic acquisition creates significant value for both sets of shareholders by combining world-class, highly complementary data and technology platforms enabling new offerings to better serve our clients and drive growth,” said Wren.

"Through this combination, we are poised to accelerate innovation and harness the significant opportunities created by new technologies in this era of exponential change. Now is the perfect time to bring together our technologies, capabilities, talent and geographic footprints to bring clients superior, data-driven outcomes. We are excited to welcome Philippe and the entire Interpublic team to the Omnicom family."

"This combination represents a tremendous strategic opportunity for our stakeholders, amplifying our investments in platform capabilities and talent as part of a more expansive network," said Philippe Krakowsky, Interpublic’s CEO.

"Our two companies have highly complementary offerings, geographic presence and cultures. We also share a foundational belief in the power of ideas, enabled by technology and data.

"By joining Omnicom, we are creating a uniquely comprehensive portfolio of services that will make us the most powerful marketing and sales partner in a world that’s changing at speed. We look forward to working with John and the entire Omnicom team," Krakowsky added.

The agreement will see Interpublic shareholders receive 0.344 Omnicom shares for each share of Interpublic common stock they own. Following the close of the transaction, Omnicom shareholders will own 60.6% of the combined company, and Interpublic shareholders will own 39.4% on a fully diluted basis. The transaction is expected to generate annual cost synergies of $750 million.

The stock-for-stock transaction is expected to be tax-free to both Omnicom and Interpublic shareholders and is expected to close in the second half of 2025, subject to Omnicom and Interpublic shareholder approvals, required regulatory approvals, and other customary conditions.
