Omnicom agrees to merge with IPG; each IPG share converts to 0.344 Omnicom shares
On December 8, 2024, Omnicom agreed to merge with The Interpublic Group of Companies (IPG) in a deal where IPG survives as a wholly owned Omnicom subsidiary. Each share of IPG common stock would convert into 0.344 shares of Omnicom common stock, with cash paid for fractional shares and certain IPG equity awards settled in cash. Completion depends on stockholder approvals from both companies, antitrust and foreign investment clearances, and other conditions, so IPG and Omnicom shareholders face a deal that is not yet final.
Key points
- Each IPG common share converts into 0.344 Omnicom common shares at the Effective Time.
- Omnicom would pay IPG $676 million if the Merger Agreement is terminated over an Omnicom board recommendation change or willful non-solicitation breach; IPG would pay Omnicom $439 million in the parallel cases.
- Philippe Krakowsky, IPG's chief executive, would become Omnicom Co-President and Co-Chief Operating Officer, and three IPG-designated directors would join the Omnicom board.
- The merger must close by December 8, 2025, which may be extended to June 8, 2026 if certain regulatory approvals are not obtained.
