Marketing agency core organic revenue growth measures growth in agency core-operations revenue after removing foreign-currency effects under Omnicom's issuer-defined methodology.
Omnicom reported 6.1% organic growth in Core Operations revenue for the second quarter of 2026. Core Operations revenue was $5.995B, compared with $5.592B for the combined prior-year base.
Organic growth sits inside a post-merger core perimeter
Omnicom defines Core Operations by excluding businesses disposed of or classified as held for sale, while the 2025 comparison uses combined Omnicom and IPG results.
That makes the growth rate specific to the post-merger reporting perimeter.
Organic growth is not discipline mix
The aggregate rate combines very different service lines and geographies.
Compare it with Integrated Media revenue mix and core adjusted EBITA margin.
