Omnicom Group Inc. reported a strong jump in fourth-quarter revenue following the completion of its acquisition of Interpublic Group, even as deal-related costs pushed the company into a net loss for the quarter.
Revenue for the three months ended December rose 27.9% year-on-year to $5.53 billion, compared with $4.32 billion in the same period last year. The growth was driven by solid organic performance and the inclusion of one month of Interpublic’s revenue after the acquisition closed on November 26, 2025.
On an adjusted basis, Omnicom posted earnings per share of $2.59. However, under GAAP accounting, the group recorded a net loss of $941.1 million, or $4.02 per share. The loss reflected acquisition-related charges, repositioning expenses, and losses tied to planned asset disposals following the Interpublic deal.
Adjusted EBITA increased 28.6% to $928.9 million, while margins improved slightly to 16.8% from 16.7% a year earlier, signaling early efficiency gains from integration efforts.
Media & Advertising remained Omnicom’s largest business segment, contributing 60.1% of quarterly revenue. Precision Marketing accounted for 10.3%, while Public Relations contributed 9.1%, underscoring the group’s diversified services mix.
Chairman and CEO John Wren said that since closing the acquisition, Omnicom has rolled out leadership and brand changes, refreshed its enterprise growth strategy, and launched the next generation of its Omni data and technology platform.
Looking ahead, Omnicom has doubled its cost synergy target to $1.5 billion, with $900 million expected in 2026. The board has also approved a $5 billion share buyback programme, including a $2.5 billion accelerated repurchase, reflecting confidence in the group’s long-term outlook.
