Omnicom Acquiring Interpublic In $13B Deal Creating World’s Largest Advertising Firm

deadline.com:

Omnicom is acquiring Interpublic in an all-stock deal that will reshape the advertising and marketing sectors, creating the world’s largest ad firm.

The transaction, valued at around $13 billion, was announced Monday morning. Interpublic shares jumped 11% on the news, while Omnicom stock slid 7%, with the moves emulating the classic pattern of a merger.

Of the four major holding companies, Omnicom and Interpublic are Nos. 3 and 4, respectively, based on revenue. Only Publicis and WPP are larger.

The majors have not tried to combine since Pubicis and Omnicom announced a merger in 2013, though the proposed transaction was never completed.
