(the “ Company ”), Omnicom Group Inc. (“ Omnicom ”), and John D. Wren entered into an amended and restated employment agreement (the “ Employment Agreement ”) pursuant to which Mr. Wren’s term as Chairman and Chief Executive Officer (“ CEO ”) of Omnicom will continue through December 31, 2028 (the “ Renewal Term ”). During the Renewal Term, Mr. Wren is expected to continue to focus on ensuring the future, long-term success of Omnicom and advancing key strategic initiatives, including completion of the pending acquisition of The Interpublic Group of Companies, Inc. (“ IPG ”), the successful integration of IPG following completion, and the continued transformation of Omnicom’s business in this new era of marketing. Mr. Wren is also expected to continue to focus during the Renewal Term on succession planning, working with Omnicom’s Lead Independent Director and Board of Directors (the “ Board ”) to identify his successor as CEO to ensure a smooth succession process. At the end of the Renewal Term, Mr. Wren will step down as CEO but will remain employed as Executive Chairman of the Board while he remains on the Board.   Pursuant to the Employment Agreement, Mr. Wren’s employment may only be terminated prior to the end of the Renewal Term by the Company for cause (within the meaning of the Omnicom Senior Executive Restrictive Covenant and Retention Plan), due to death, or pursuant to Mr. Wren’s resignation for any reason.   Under the terms of the Employment Agreement, Mr. Wren’s annual base salary will be reduced from $1 million to $1.00 effective June 1, 2025. On May 12, 2025, Mr. Wren was granted a stock option to purchase 4,000,000 shares of Omnicom common stock at a per share exercise price equal to the per share closing price of Omnicom common stock on the date of grant. Such option is scheduled to vest pro-rata over the Renewal Term. Pursuant to the Employment Agreement, Mr. Wren will not be entitled to receive any additional incentive compensation during the Renewal Term.   Mr. Wren has successfully led Omnicom as CEO since 1997, and he remains committed to working during the Renewal Term to mark three highly successful decades in the role. Mr. Wren’s agreement to receive an at-risk equity award in lieu of other compensation aligns Mr. Wren’s incentives directly with the interests of Omnicom’s shareholders as his future compensation will be tied entirely to the future performance of Omnicom.   The foregoing description of the Employment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Employment Agreement, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.   Safe Harbor Statement for Forward-Looking Statements   This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
