Omnicom Completes Acquisition of Interpublic, Forming the World’s Leading Marketing and Sales Company, Built for Intelligent Growth in the Next Era : Omnicom announced the successful completion of its acquisition of The Interpublic Group of Companies, Inc. (IPG), marking a historic moment in the global marketing and communications industry. With all regulatory approvals secured and closing conditions satisfied, the merger cements Omnicom’s position as the world’s leading marketing and sales company, engineered for intelligent growth in a rapidly evolving landscape.
The combined entity brings together the industry’s most extensive and connected portfolio of capabilities, seamlessly integrated through Omni—Omnicom’s advanced intelligence platform. By uniting data, creativity and technology with world-class talent, the new Omnicom aims to help global clients accelerate growth, strengthen brand equity and outperform in competitive markets.
“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.”
A Transformational Combination
Under the terms of the agreement, Interpublic shareholders received 0.344 Omnicom shares for each Interpublic common stock they held. Following the merger, legacy Omnicom shareholders hold approximately 60.6% of the combined company, while legacy Interpublic shareholders own about 39.4%, on a fully diluted basis.
The newly combined company, with pro forma annual revenue exceeding $25 billion, will continue to trade under the ticker symbol OMC on the New York Stock Exchange.
This strategic consolidation creates a new global benchmark for integrated marketing services. Omnicom’s already robust ecosystem now expands further with IPG’s celebrated agencies such as McCann Worldgroup, FCB, MullenLowe Group, Mediabrands, R/GA, Huge, Weber Shandwick, and Golin — enhancing the company’s capabilities across creative, media, digital transformation, public relations, health communications, and experiential marketing.
IPG’s Legacy Strengthens the New Omnicom
Founded in 1930, the Interpublic Group (IPG) has long been recognized as one of the “Big Four” global advertising and marketing holding companies. IPG built a reputation for excellence in creativity, integrated communications, and data-driven marketing solutions. The group has won numerous international awards across its agency networks and has played a pivotal role in shaping modern advertising strategies for global brands.
IPG’s strengths in digital transformation, purpose-driven campaigns, health marketing, and media innovation will significantly enhance the capabilities of the combined organization. The addition of IPG’s talent, insights, and cutting-edge platforms deepens Omnicom’s ability to offer end-to-end, intelligence-powered solutions for clients navigating the next era of marketing.
Leadership Continuity Ensures Stability
As previously announced:
- John Wren remains Chairman & CEO
- Phil Angelastro continues as EVP & CFO
- Philippe Krakowsky (former IPG CEO) and Daryl Simm will serve as Co-Presidents and COOs
Additionally, Philippe Krakowsky, Patrick Moore, and E. Lee Wyatt Jr. have joined Omnicom’s Board of Directors, ensuring IPG’s strategic perspective is represented at the highest level.
Omnicom has confirmed that the company’s full leadership team will be revealed on December 1, 2025, signaling a renewed era of consolidated excellence and unified global strategy.
A New Era for Global Marketing and Communications
With this merger, Omnicom becomes the most integrated and future-ready marketing and sales organization in the world. The company’s Connected Capabilities — spanning media, commerce, precision marketing, advertising, production, health, public relations, branding, experiential and data analytics — now benefit from the expanded reach and expertise of IPG’s globally trusted brands.
The combined teams will focus on empowering clients to tackle their most critical growth priorities, from digital acceleration and customer experience transformation to omni-channel creativity and performance-driven marketing.
