In the past decade, mergers and acquisitions among advertising agencies have been particularly active during economic downturns.

However, marketing and advertising have stalled under the overregulation of the Biden administration.

That’s now changing, and marketing and advertising are hot again.

Large companies are on a marketing and advertising hunt. If the deal goes through, Omnicon and IPG will become the largest ad agency in the world.

1) Here are the key details regarding Omnicon’s acquisition of Interpublic Group:

  • Transaction Details: Omnicon is acquiring Interpublic Group in a $13.3 billion all-stock deal. IPG shareholders will receive 0.344 shares of Omnicon for each IPG share they own. Upon completion, Omnicon shareholders will own 60.6% of the combined entity, while IPG shareholders will hold 39.4%.
  • Timeline: The deal is expected to close in the second half of 2025, pending shareholder approval, regulatory clearance, and other conditions.
  • Combined Scale: The merger will create the largest advertising agency globally, with over 100,000 employees and projected annual revenue exceeding $25.6 billion.
  • Strategic Goals: The merger aims to strengthen competitiveness against Big Tech and AI-driven advertising tools by combining complementary data, technology platforms, and geographic reach. It’s projected to generate $750 million in annual cost synergies.
  • Clients: Some of their clients include Amazon, AT&T, PepsiCo, Unilever, and Volkswagen.
  • Market Reaction: IPG shares surged 10–15% after the announcement, while Omnicon shares dropped 4–6%, reflecting mixed investor sentiment about the integration challenges and market dynamics.
