Omnicom chief John Wren reported a 9.3 percent tumble in Q4 revenues to $3.8B as the COVID-19 pandemic took a toll on its business. Organic growth dipped 4.9%, to $614.7M.

The PR group (Marina Maher Communications, Portland, FleishmanHillard, Cone, Porter Novelli, Mercury and Ketchum) posted a 1.9 percent drop in reported revenue to $351M and a 5.6 percent decline for the full year to $1.3B.

It was the only unit to post positive Q4 organic growth, +0.2 percent.

Advertising dropped 9.7 percent, CRM consumer experience plunged 15.8 percent, CRM executive & support fell 13.7 percent and healthcare slipped 2.0 percent.

Omnicom reported organic declines across all regions. The US was down 9.4 percent; UK, 12.4 percent; Europe, 9.2 percent; Asia Pacific, 3.9 percent; and Middle East & Africa, 36.8 percent.
