Omnicom Group reported a net loss of $941.1 million for the fourth quarter of 2025, a significant reversal from the $448.0 million net income reported during the same period in 2024, according to results released Wednesday.
The financial results mark the first full quarterly reporting period since Omnicom completed its acquisition of Interpublic Group (IPG) on November 26, 2025. Despite a 27.9% increase in revenue to $5.5 billion, up from $4.3 billion in the fourth quarter of 2024, the integration of IPG contributed to a substantial operating loss of $977.2 million, compared to an operating income of $685.3 million in the prior year.
For the full year 2025, Omnicom recorded a net loss of $54.5 million, contrasting with a net income of $1.8 billion in 2024. Full-year revenue increased to $17.3 billion, from $13.7 billion the previous year. The company cited increased net interest expense, rising $19.5 million to $166.5 million in 2025, as a factor impacting the results, attributing the increase primarily to the IPG acquisition and the associated exchange of IPG debt for Omnicom debt.
“Since the successful closing of the Interpublic acquisition on November 26, we made key leadership and brand announcements, refreshed our enterprise growth strategy and launched the next generation of our Omni data and technology platform,” said John Wren, Chairman and Chief Executive Officer of Omnicom. The company has set a goal of achieving $1.5 billion in total cost synergies, including $900 million in 2026, following the IPG acquisition.
Omnicom’s Board has authorized a $5.0 billion share buyback, including a $2.5 billion Accelerated Share Repurchase program. Non-GAAP adjusted EBITA for the fourth quarter was $928.9 million with a 16.8% margin. For the full year, Non-GAAP adjusted EBITA reached $2.7 billion, representing a 15.6% margin.
The acquisition of IPG, valued at $25 billion, is expected to create the world’s leading marketing and sales company, leveraging Omnicom’s creative expertise and IPG’s data-driven media capabilities. The merger aims to generate $750 million in annual synergies by 2026 through geographic expansion, cross-selling, and reductions in SG&A costs via shared platforms.
Revenue for the fourth quarter was driven by Media Advertising, accounting for 60.1% of the total, followed by Precision Marketing at 10.3% and Public Relations at 9.1%. Geographically, the United States contributed 51.9% of total revenue, with additional revenue coming from Euro Markets and the Asia Pacific region.
