The European Commission announced on November 24, 2025 that it has granted unconditional antitrust approval for Omnicom Group’s all‑stock acquisition of The Interpublic Group of Companies, Inc. (IPG). The clearance removes the last regulatory obstacle for the deal, allowing the transaction to close by the end of business on Wednesday, November 26, 2025.
The transaction values IPG at roughly $13.3 billion to $13.5 billion, with Omnicom shareholders receiving 60.6 % of the combined company and IPG shareholders 39.4 %. The combined entity will report about $25.6 billion in annual revenue and is targeting $750 million in annual cost synergies, driven by overlapping agency functions, technology platforms and back‑office consolidation.
The merger is positioned as a strategic response to the rapid rise of data‑driven and AI‑powered advertising. By combining Omnicom’s Omni and Omni AI platforms with IPG’s Acxiom data capabilities, the new company aims to offer a full‑stack, end‑to‑end marketing solution that can compete with tech giants such as Google and Meta. The deal also expands geographic reach, deepens creative and media capabilities, and creates a scale that can deliver higher pricing power and better client retention.
John Wren, Omnicom’s chairman and CEO, said the approval “is a critical step toward creating the world’s leading marketing and sales company.” Philippe Krakowsky, IPG’s CEO, added that the merger “positions us to meet the evolving needs of clients in a consumer and media landscape being transformed by technology and data.” Both executives highlighted the importance of disciplined cost management and the integration of AI tools to accelerate growth.
Analysts have responded positively, citing the deal’s potential to unlock significant synergies and strengthen the combined group’s competitive position. The FTC’s consent order, which requires viewpoint neutrality in ad placement, is a unique regulatory condition that underscores the merger’s focus on maintaining fair competition while expanding scale.
The approval also signals that the FTC’s consent order and other global regulatory reviews—completed in the U.S., U.K., India and Australia—have been satisfied. Integration challenges remain, including cultural alignment, overlapping agency brands, and the need to cut approximately 20 % of global headcount to achieve the targeted cost savings. Nonetheless, the combined entity is expected to become the largest advertising conglomerate by revenue, reshaping the industry’s competitive landscape.
