ACCC approves aquisition of IPG by Omnicom Group

Omnicom (OMC) and Interpublic (IPG) have announced that the Australia Competition and Consumer Commission (ACCC) has granted clearance for Omnicom’s pending acquisition of Interpublic.

With this approval, 14 out of the 18 required antitrust approvals for the transaction have now been received. Both companies stated they remain on schedule to complete the acquisition in the second half of 2025.

According to the involved companies, the merger is intended to combine their marketing capabilities and is expected to bring changes to service offerings for clients and shareholders.

Other key approvals have come from China, India, Japan, Brazil, Egypt, Singapore, Columbia and Saudi Arabia. Major markets like the United States, the European Union, and the United Kingdom are still in the review phase. The merger has also received approval in New Zealand.

According to media reports, this merger is said to create the world's largest integrated communications group, generating approximately $26 billion in annual revenue. In India, the combined entity will become the second-largest advertising and marketing communications firm.

Omnicom had announced its plan to acquire IPG in an all-stock transaction in December 2024.
