Revenue from Core Operations in the third quarter of 2026 increased $407.4m, or 7.3%, to $6bn as compared to the third quarter of 2025, primarily due to organic growth of $400.8m, or 7.2%, and an increase due to foreign currency translation of $3.4m or 0.1%.
Core Operations are calculated from the consolidated revenue, adjusted operating income and adjusted EBITA of Omnicom, excluding results of businesses that have been disposed of up to the date of disposition in 2026 and businesses classified as held for sale. Amounts for 2025 are calculated on a combined basis for Omnicom and IPG.
“As we approach the first anniversary of the Interpublic acquisition, we continue to deliver the expected benefits of the combination,” says John Wren, chairman and chief executive officer of Omnicom.
“We’ve strengthened our competitive position and are on track to deliver $900m in cost-reduction synergies in 2026, resulting in stronger organic revenue growth, operating margins, and earnings per share,” says Wren.
He adds, “With our integration nearly complete and our portfolio of companies and operations streamlined, we’re focused on high-demand services and are well positioned to pursue future growth.
“We’ll continue investing in our people and agentic technology to drive measurable business outcomes for our clients.”
