Omnicom Group has announced plans to exit approximately $2.5 billion in annual revenue from non-core businesses over the next 12 months, as part of its broader portfolio restructuring following the acquisition of Interpublic Group (IPG).

Speaking during the company’s fourth-quarter earnings call, CEO John Wren confirmed that Omnicom has already divested businesses generating more than $800 million in annual revenue. The remaining exits are expected to be completed within a year. Additionally, the group will transition from majority to minority ownership in select smaller markets contributing roughly $700 million in annual revenue, which are no longer aligned with its long-term strategic priorities.

Following the IPG integration, Omnicom has doubled its targeted annual run-rate synergies to $1.5 billion over 30 months. Of this, approximately $900 million is projected to be realized in 2026, driven primarily by labour cost efficiencies and structural simplification. The company is also ramping up investments in automation and artificial intelligence to enhance operational productivity and client solutions.

For Q4 FY26, Omnicom reported revenue of $5.53 billion, supported by organic growth and early contributions from IPG. The quarter also saw new or expanded mandates from global clients including American Express, Bayer, Mercedes-Benz and NatWest Group, reinforcing momentum as the company sharpens its strategic focus.
