US EditionOmnicom Closes $13B IPG Deal, Uniting Rivals in Industry-Shaping Acquisition
The $9 billion all-stock acquisition merges Omnicom and Interpublic, creating an ad giant with $25 billion annual revenue and plans for 20,000 job cuts, analysts say.
- On Wednesday, Omnicom Group completed its $9 billion all-stock acquisition of Interpublic Group of Companies, creating the largest advertising holding company by revenue after regulatory approvals.
- Company executives argued consolidation was motivated by a belief that being bigger is the best strategy, while Omnicom Group and Interpublic Group sought cost cuts and better media deals amid pressures from consultancies, private-equity-backed networks and in-housing efforts.
- Financial disclosures show the combined firm will post $25.6 billion in revenue, adjusted EBITDA of $3.9 billion, free cash flow of $3.3 billion, with legacy Omnicom Group shareholders owning 60.6% and Interpublic Group shareholders 39.4%, and the transaction expects $750 million in synergies.
- Analysts warn the merger could lead to 20,000 job cuts, with IPG and Omnicom employees already losing 3,200 and 3,000 roles this year, while the Federal Trade Commission imposed a consent decree limiting ad coordination.
- Omnicom plans to reveal its full leadership team on December 1, 2025, and industry analysts anticipate further ad-agency consolidation as the global advertising market tops $1 trillion in 2025.
