Omnicom Media has been named the best-performing global media group in the latest Network Diagnostics report by the Research Company Evaluating the Media Agency Industry (RECMA). It is the only group to top the rankings simultaneously across North America, Europe Middle East and Africa (EMEA), Asia Pacific and Latin America.

HAVAS Media Network, Publicis Groupe, dentsu and WPP followed in that order to complete the top five.

RECMA’s bi-annual Diagnostics report is widely regarded as one of the most rigorous assessments of media agency performance. It evaluates approximately 700 agencies across 45 markets using 19 KPIs. The methodology goes beyond billings and new business wins. It also scores client portfolio stability, digital and data resources, and consistency across geographies.

Omnicom Media was awarded the Dominant profile — the report’s highest distinction — in 19 markets. That is more than any other media group across all four regions.

Scale Meeting Quality

Omnicom Media was formally created in December 2025 through the integration of Omnicom Media Group and IPG Mediabrands. It currently holds approximately 30 per cent of industry billings volume. In the RECMA report, it captured roughly 32.4 per cent of quali-share in EMEA alone — about 50 per cent higher than the second-ranked group in that region.

Four of the top ten best-performing individual media agencies were Omnicom Media brands. OMD ranked first for the eleventh consecutive report. PHD, Initiative and UM also featured in the top ten.

CEO Florian Adamski said the results validate the group’s founding logic. “The goal was never to simply be the biggest,” he said, “but to use that scale intelligently to design the leading growth ecosystem for our clients.”

Strong First 100 Days

The ranking lands as Omnicom Media marks its first 100 days as a combined entity. In that period, the group secured first-mover data partnerships with Amazon, Google, Meta, Roku, Pinterest and Walmart. Also, it also facilitated more than 30 clients’ participation in the launch of ChatGPT ads and reported $5 billion in new business wins, retentions and expansions.

Recent client additions include Delta, Dyson and streaming platform SkyShowtime.

OMD separately ranked first by billings volume in RECMA’s July 2025 activity analysis, recording close to $35.6 billion in total billings, outperforming its nearest competitor by $4.4 billion with year-on-year growth of over 9.5 per cent.
