Omnicom acquisition of Interpublic Group made official
Omnicom’s acquisition of Interpublic Group has been unanimously approved by Board directors at both companies, with a definitive agreement made this week.
Under the terms of the agreement, for each Interpublic common stock they own, Interpublic shareholders will receive 0.344 Omnicom shares. Following the close of the transaction, Omnicom shareholders will own 60.6% of the combined business, and Interpublic shareholders will own 39.4%, on a fully diluted basis.
The transaction is expected to generate annual cost synergies of $750 million. The combined company will retain the Omnicom name and trade under the OMC ticker symbol on the New York stock exchange.
The stock-for-stock transaction is expected to be tax-free to both Omnicom and Interpublic shareholders and is expected to close in the second half of 2025, subject to shareholder approvals, required regulatory approvals, and other customary conditions.
