Catenaa, Monday, December 01, 2025- Omnicom will lay off more than 4,000 employees and fold several well-known advertising agency brands after its $13.5 billion acquisition of rival Interpublic Group.
The Financial Times reported on Monday, stating that the deal has turned Omnicom into the world’s largest advertising agency by revenue, leapfrogging France’s Publicis and pushing WPP into third place, re-centring the advertising industry around the “Mad Men” of New York’s Manhattan.
The combination of Omnicom and IPG, which collectively run dozens of agencies, will result in the closure of some of the industry’s most historic names.
Creative agency DDB, founded in 1949 and led by influential adman William Bernbach, and the creative marketing agency MullenLowe will be folded into Omnicom’s TBWA, company executives said in an interview with the Financial Times.
Omnicom boss John Wren said more than 4,000 jobs would be cut as part of the integration of IPG, mainly in administrative roles, but some leadership positions too.
The cuts, say Omnicom executives, should be seen against the backdrop of similar restructuring at rivals such as WPP, which is also expected to axe jobs under new boss Cindy Rose.
“There’s efficiencies, they come in the form of labour and other things,” Wren said. “But anybody that was generating revenue before December last year has a very good position with us today.”
The new round of job losses comes on top of thousands already announced by both companies since the deal was agreed last year.
IPG cut 2,400 jobs in the first half of 2025, in addition to about 4,000 jobs last year, reducing headcount to approximately 51,000. Omnicom last year reduced staff numbers by 3,000 to about 75,000.
Omicron Stock fell by over 2% on Monday morning, following the news report.
