Omnicom is reporting a Q1 revenue hike of +3.4%, led by “strong growth” in its its media and advertising business.

The company, whose agency networks include BBDO, DDB and TBWA, reported Q1 profit of $486.4 million, excluding acquisition costs, up 1.6% for the quarter ended March 31, 2025. The company lowered its full-year organic growth guidance, however, due to economic instability.

In Tuesday’s earnings call Q&A, the company CEO John Wren admitted to “quite a bit of uncertainty” in its business overall because of ongoing tariffs. Wren stressed that no specific client has taken action in response just yet, and he said the company is hoping for more clarity from the Trump administration going forward.

While Omnicom’s advertising, media and CRM “remains strong,” Wren conceded there are “doubts” about the events business.

Organic growth by discipline in the first quarter of 2025 compared to the first quarter of 2024 was as follows: 7.2% for media and advertising, 5.8% for precision marketing and 1.9% for execution and support. Its media strength was partially offset by declines of: 10.0% for branding and retail commerce (the latter because the branding business is linked to merger and acquisition activity), 4.5% for public relations, 3.2% for healthcare and 1.5% for experiential.

Pharma and health (15%), food and beverage (15%), auto (13%), consumer items (9%) were the top revenue sectors, followed by financial services (8%) and travel and entertainment (8%). According to Wren, Pharma and health’s slight declines were in part due to the loss of client, Pfizer, however he maintained it’s “still a very strong business.”

By geography, organic growth in Latin America led the way at 14.8%, followed by Asia Pacific (6%), the U.S. (4.6%) and European markets (1.7%). This was offset by declines of 9.3% for the Middle East and Africa, 3.6% for Other North America (which includes Canada), and 0.7% for the U.K.

Finally, regarding the IPG acquisition, Wren said it did not have any any client of any significance that it was in fear of losing because of the transaction. Potential client losses stemming from a merger between Omnicom and IPG, Wren claims, is “nonsense fed by my competitors to the trade rags.”
