Omnicom has announced the successful completion of its acquisition of The Interpublic Group of Companies, following the receipt of all required regulatory approvals and fulfilment of closing conditions. The consolidation has created a unified marketing and sales company positioned as the world’s largest in its category.
The combined organisation has brought together a wide-ranging portfolio of capabilities, powered by Omni, the company’s intelligence platform. The integration has reimagined how data, creativity and technology work alongside talent to support clients’ growth priorities.
