Omnicom Group shook up the advertising world in December by announcing its plan to buy rival Interpublic Group of Cos. in a deal that would create the world’s largest agency holding company.
The pending deal, expected to close in the second half of 2025, would combine two companies with a total revenue of $25.6 billion in 2023, surpassing WPP’s $18.5 billion. The all-stock deal is expected to generate $750 million in annual cost synergies, which means layoffs are likely. For now, the proposed entity would bring together more than 100,000 employees.
