Interpublic Sees Organic Net Revenue Decrease 3.6% in 1H25 as It Prepares for Its Merger with Omnicom

This IDC Market Note highlights Interpublic's (IPG's) financial results and the company's plans to merge with Omnicom. Interpublic published its 1H25 financial results on July 22, 2025, showing net revenue excluding billable expenses of 3.6% organically to $4.2 billion. IPG is heading into its projected merger with Omnicom in 4Q25, with a collection of often impressive assets - notably Acxiom and IPG Mediabrands - that will serve the expanded Omnicom well. If IPG does somehow remain independent, it will have to address issues holding back growth, notably its relative weakness in CX professional services.
