Omnicom's overall revenue in the first quarter of 2026 increased by USD 2.6 billion to USD 6.2 billion as compared to the first quarter of 2025, primarily due to the acquisition of IPG, which closed on 26 November 2025. The revenue also increased due to currency revenue growth. The impact of foreign currency translation increased revenue by USD 174.2 million, or 4.8%. Revenue in the first quarter of 2026 includes USD 627.2 million from dispositions and assets held for sale.

John Wren, chairperson and CEO, Omnicom, said, “Our strong first quarter performance as the new Omnicom reflects our new integrated capabilities, core portfolio operations, and successful integration activities. With the largest global media platform, proprietary data and identity capabilities, and our AI-powered Omni platform in full operation, we are uniquely equipped to help clients address an increasingly fragmented and complex marketing environment. In the quarter, we delivered solid revenue growth and double-digit growth in Non-GAAP adjusted diluted EPS. We are also on track to achieve substantial cost reduction synergies and USD 3.5 billion in share repurchases this year under our USD 5 billion authorisation. This combination of operational excellence and disciplined capital allocation positions us to deliver profitability and earnings-per-share growth that will set a new standard for our sector.”

Omnicom's revenue for its core operations (excludes businesses that have been disposed of or are held for sale) grew by USD 350.9 million (6.7%) to USD 5.6 billion in comparison to the first quarter of 2025. 

This increase came due to an increase in organic revenue of USD 206.7 million (3.9%) and an increase due to foreign currency of the balance (USD 144.2 million).

Revenue contribution by discipline as a percentage of revenue from core operations of USD 5.6 billion in the first quarter of 2026 was as follows: 

• USD 2.9 billion, or 51.5%, for integrated media
• USD 943.4 million, or 16.8%, for advertising
• USD 535.5 million, or 9.5%, for health 
• USD 659.8 million, or 11.7%, for public relations 
• USD 582.8 million, or 10.4%, for experiential and other 

The group reported USD 627.2 million revenue from dispositions and assets held for sale.
