As reported by the Financial Times, Omnicom will also be cutting more than 4,000 jobs and closing several advertising agencies as part of an immediate restructuring following its merger with IPG.
Omnicom announced executive leadership changes on 1 December 2025, following the completion of its acquisition of Interpublic (IPG) on 26 November 2025.
The newly combined Omnicom aims to bring together an integrated portfolio of capabilities supported by Omni, its intelligence platform. According to the company, these capabilities are designed to address clients’ growth priorities and provide five strategic advantages across modern marketing and sales. These stated advantages include:
- Media ecosystem: Omnicom stated that with its media network, supported by Acxiom RealID™ and ID-less solutions, this ecosystem is designed to unify paid, owned, earned, and commerce channels to improve value, precision, and measurable growth in a privacy-first environment.
- Influential content: The company said it will use generative AI to combine creativity with data-driven insights to enable personalised content at scale through its broad agency portfolio.
- Connected commerce: Omnicom reports that it will integrate commerce intelligence and capabilities across marketplaces to link marketing investment with sales performance, aiming to accelerate omnichannel growth and ROI.
- Enterprise generative AI capability: The combined entity noted that it now has expanded resources to build on Omnicom’s existing partnerships with leading AI model providers. This means the company is in a position to support efforts to redesign clients’ marketing operations for greater speed, intelligence, and growth.
- Identity leadership: Supported by the next generation of Omni and Acxiom RealID™, the company highlighted that it will provide a privacy-first understanding of audiences worldwide without relying on third-party cookies.
According to an article by the Financial Times, the company is said to be cutting more than 4,000 jobs and shutting several of its advertising agency brands as part of an immediate restructuring following the merger with IPG.
Per the article, Omnicom CEO John Wren said the restructuring will impact administrative functions as well as selected leadership roles. The latest round of job cuts follows thousands already announced by both Omnicom and IPG since the deal was agreed in 2024.
At IPG, according to Financial Times, 2,400 jobs were eliminated in the first half of 2025, on top of about 4,000 cuts the previous year, bringing its headcount to roughly 51,000. Omnicom also reduced its workforce by 3,000 over the same period, bringing its total to about 75,000 employees.
HRO has reached out to Omnicom for a statement and will update the article once a response is received.
