Omnicom

Ad- Grow My Agency

Depending on your location, you may be waking up to news of the 'New' Omnicom. Nearly a year after the initial announcement, Omnicom has officially completed its $13.5 billion acquisition of Interpublic Group, making it the largest advertising and marketing holding company in the world by revenue and billings.

Under the all-stock agreement, Omnicom shareholders will own 60.6% of the combined company’s shares, while IPG shareholders will hold 39.4%. The merged companies reported an estimated $26 billion in annual revenue for 2024.

The deal makes Omnicom the world's largest holding company, with revenue of $26.4 billion.


There are still several details to work out with the mega-network that controls a vast swathe of media, data, CRM and creative assets under one roof – at exactly the moment AI is rewiring how those disciplines connect. 

CMO's will also have to make some tough decisions as to whether to stay with Omnicom, considering they may now be run by a company that also services its direct competitor.


“This is a defining moment for our company and our industry,” said John Wren, Chairman and CEO of Omnicom. “With the completion of the deal, Omnicom is setting a new standard for modern marketing and sales leadership — creating stronger brands, delivering superior business outcomes, and driving sustainable growth. We’re excited about this next chapter. I want to thank our people, clients, and shareholders for the trust they have placed in us.”  

Will brands stay or go? What promises will Omnicom have to make to prevent any further client loss?
