The merger was announced on December 9, 2024 and was completed November 26, 2025. It took almost a year to complete, and it’s now the world’s largest advertising holding company.
Omnicom + IPG merger and reorganization eliminatesDDB, FCB, and MullenLowe. Over the next 6 months, those 3 agencies will fold into Omnicom agencies.
BBDO absorbs FCB
TBWA absorbs:
MullenLowe
DDB
The team that services Volkswagen will be known as “Bernbach”
Adam&Eve merges into TBWA across UK, US, and Germany. Will be known as adam&eve TBWA in London.
IPG agencies (including Martin and Deutsch) move into the U.S. Advertising Collective (part of Omnicom Advertising Group).
Omnicom’s new U.S. Advertising Collective includes: Goodby, GSD&M, Martin, Deustch, Zimmerman, Lucky Generals, Merkley & Partners, and Carmichael Lynch (referred to as “a collection of smaller, creative boutiques”)
McCann remains the sole IPG global creative network. Reasons are because of established global footprint and brand awareness.
While Omnicom made significant changes to the creative side of its business, its media operations are largely untouched.
Earlier this year, IPG agencies have already cut 3200 jobs and Omnicom agencies have already cut 3000 jobs. It’s estimated that 4000 more jobs will be cut this month. The result is an 18% overall reduction of staff compared to EOY 2024.
