Interpublic Group prepares for its merger with Omnicom by cutting 3,200 jobs and vacating over 700,000 square feet of office space, as the advertising giants streamline operations ahead of a landmark $13.5 billion deal.
Interpublic Group (IPG) has undertaken significant workforce reductions and office space consolidations as it prepares for its imminent $13.5 billion merger with Omnicom Group, a deal set to create the world’s largest advertising agency by revenue. According to the company’s latest SEC filing, IPG cut approximately 3,200 jobs globally, including 800 layoffs in the third quarter of 2025 alone. Alongside these personnel changes, the holding company vacated over 700,000 square feet of office space, a move aimed at streamlining operations and reducing costs as it approaches the final stages of the merger, which is expected to close by the end of November 2025.
The restructuring initiative at IPG is part of a larger transformation programme designed to optimise expenses ahead of the merger. Industry sources indicate the process is projected to cost between $450 million and $475 million, covering severance packages, lease impairments, and related expenses. The layoffs have impacted various roles across the company, although specific positions affected have not been publicly detailed. This operational trim aligns with efforts to enhance efficiency as the two advertising giants prepare to merge their businesses, which will bring together billions in revenue and tens of thousands of employees worldwide.
Meanwhile, Omnicom Group, IPG’s merger partner, has also taken steps to pare down its workforce in anticipation of the deal. Over the course of 2024, Omnicom cut an estimated 3,000 roles, reducing its global headcount from approximately 77,900 in January 2024 to around 74,900 by the end of that year. The merger arrangement will result in Omnicom shareholders owning 60.6% of the newly combined entity, with IPG shareholders holding the remaining 39.4%, reflecting the shared ownership structure forged at the announcement of the deal in December 2024.
Omnicom’s 2024 Annual Report provides additional context, highlighting the strategic rationale and challenges associated with the merger. The report outlines expected benefits such as cost savings and operating synergies from integrating corporate functions and aligning operating practices across the two organisations. However, it also notes risks, including the complexities of harmonising operations within this larger diversified business and managing the combined workforce effectively.
The proposed combination of these two powerhouse advertising holding companies is poised to reshape the global marketing industry, consolidating their reach, client portfolios, and resources. Yet, as both IPG and Omnicom undertake significant workforce reductions and operational changes, the scale of integration required and associated costs underscore the challenges that lie ahead before the merger reaches completion.
