OMNICOM GROUP INC. (OMC)

Omnicom is a strategic holding company that operates through global networks, connected capabilities and specialized agencies to deliver marketing, sales, communications and commerce services to many of the world's largest companies. Its offerings support client objectives in media, content, commerce, generative AI and branding communications. On November 26, 2025, Omnicom completed its merger with The Interpublic Group of Companies (IPG), which became a wholly owned subsidiary. Legacy Omnicom shareholders own about 60.6% of the combined company and legacy IPG shareholders about 39.4%. Omnicom was the accounting acquirer, so IPG's results are included only from the closing date. Omnicom's common stock trades on the NYSE under "OMC."

The business is organized into four global networks: Omnicom Advertising (BBDO, TBWA, McCann and the Advertising Collective brands), Omnicom Media (OMD, PHD, Hearts & Sciences, UM, Acxiom, Initiative and Mediahub), the DAS Group of Companies (including Omnicom Precision Marketing, MRM and Omnicom Health/IPG Health), and the Communications Consultancy Network (FleishmanHillard, Ketchum, Golin and Weber Shandwick). Services span media and advertising, precision marketing, public relations, healthcare, branding and retail commerce, experiential marketing, and execution and support. They include media planning and buying, creative and content production, data analytics, CRM, e-commerce, crisis communications, field marketing and sports and event marketing. All agencies are supported by Omni, a proprietary marketing intelligence platform that includes Acxiom, Interact and Flywheel Commerce Cloud, identity and data management, and generative AI tools. A next-generation version was unveiled in January 2026.

Omnicom's clients operate in virtually every sector, and no industry accounted for more than 15% of 2025 revenue. The largest client represented 2.4% of revenue and was served by about 144 agencies. The 100 largest clients made up about 54% of revenue and were each served by roughly 55 agencies on average. Revenue is generally balanced between the United States and international markets, and the geographic markets are the Americas, Europe, the Middle East and Africa, and Asia-Pacific. Revenue is typically lower in the first and third quarters and higher in the second and fourth. Demand depends on client marketing spending, which is sensitive to global economic conditions.

The company uses a client-centric matrix structure in which multiple agencies collaborate through Client Success Leaders and the Global Growth Team. It grows by expanding services to existing clients, entering new markets, winning new clients and making selective acquisitions. Omnicom is headquartered in New York, New York. At December 31, 2025 it employed about 120,000 people worldwide, including 55,300 in the Americas, 38,000 in EMEA and 26,700 in Asia-Pacific, with about 37,700 in the United States. It is subject to various federal, state, local and foreign laws and regulations, which have not had a material effect on its business. In connection with the merger, Omnicom exchanged about 94% of IPG's senior notes for $2.76 billion of new Omnicom notes.
