Rhea-AI Filing Summary

Interpublic Group of Companies, Inc. (IPG) director Jorge Benitez reported the disposition of 20,940 shares of IPG common stock on 11/26/2025. The shares were transferred as part of a merger in which EXT Subsidiary Inc. merged with and into IPG, with IPG surviving as a wholly owned subsidiary of Omnicom Group Inc.

In addition, each outstanding IPG restricted stock award was converted into an Omnicom restricted stock award based on the same 0.344 exchange ratio, while keeping the original vesting and other terms.

Insights

M&A and equity compensation analyst

IPG’s merger into Omnicom converts common and restricted shares into Omnicom stock using a 0.344 exchange ratio.

The filing shows an IPG director disposing of 20,940 IPG shares due to a completed merger. IPG becomes a wholly owned subsidiary of Omnicom Group Inc., and IPG common stock is replaced by Omnicom common stock, so the director’s IPG holdings move out of the standalone public float.

Each IPG share is converted into the right to receive 0.344 Omnicom shares plus cash for fractional shares, setting a clear equity exchange mechanic. Outstanding IPG restricted stock awards are similarly converted into Omnicom restricted stock awards at the same ratio, while retaining their prior terms and conditions, which helps maintain continuity of incentives for the holder within the new corporate structure.
