Industry Insight Report: Advertising & PR Agencies Q4-2024
In December, advertising firm Omnicom announced it would acquire rival Interpublic Group in an all-stock deal that will create the world’s largest advertising company. The two firms had a combined 2023 revenue of $25.6 billion. Omnicom said the merger will create a company providing end-to-end services across media, marketing, CRM, data, digital commerce, advertising, public relations, and branding. The deal comes as tech firms, including Google and Meta, gain larger shares of the ad market and as big tech’s generative AI efforts are expected to further encroach on traditional ad players’ creative development space. Once the deal is complete, Omnicom shareholders will hold a 60.6% stake in the combined company, and Interpublic shareholders will own 39.4%. The transaction is expected to close in the second half of 2025, and the combined company will retain the Omnicom name.
