Omnicom owns advertising agencies and sells its people's time, its buying muscle and its data to the world's big advertisers. Since it swallowed its rival Interpublic the company is roughly twice the size it was, and the largest share of the money now comes from placing ads rather than dreaming them up. The work now is stitching two giants together, selling off the parts it does not want, and proving the joined-up machine wins accounts.

Omnicom Media
The biggest engine: planning and buying ad space for large advertisers, roughly $107B of their money placed in a year, of which only a few cents on the dollar stays with Omnicom as a fee. It grew a little over ten percent last quarter.
Competes with WPP Media (WPP) · Publicis Media (Publicis Groupe) · Dentsu media (Dentsu)
In plain English
Think of a giant buying club for ad space. Thousands of companies want to reach people on television, online and in apps; Omnicom's media agencies — OMD, PHD, UM, Initiative — decide where the ads should run and negotiate the price, buying for hundreds of clients at once so the rate beats what any one of them could get alone.
Clients pay a fee for that planning and buying. Increasingly Omnicom also buys ad space onto its own books first and resells it, keeping the difference. The money flowing through is enormous; the slice kept is small, which is why a huge new account adds only a modest amount of revenue.
Omni
The shared data-and-software spine, relaunched in January 2026 and carrying roughly 2.6 billion verified consumer identities from Acxiom. It bills nobody. Its job is to make one client hire Omnicom for media, creative and public relations at once.
Competes with Epsilon (Publicis Groupe) · Merkle (Dentsu) · Identity resolution (LiveRamp)
In plain English
Every agency in the group used to keep its own lists and its own tools. Omni is the shared one: a single set of records about who buys what, plus software that plans a campaign, places it and checks whether anything actually sold.
No client is invoiced for it. It earns its keep the way a shop's loyalty card does — the card is free, and it is the reason you come back for everything instead of splitting your basket across four shops. Management says Omni is why clients inherited from the merger stayed, and its stated first priority is software that can run campaign chores on its own.
Omnicom Advertising
The creative networks — BBDO, DDB, TBWA, McCann — that think up the ads themselves. A sixth of revenue, and the line going backwards: sales fell at a high-single-digit rate last quarter after falling the quarter before.
Competes with Ogilvy and VML (WPP) · Leo (Publicis Groupe) · Accenture Song (Accenture)
In plain English
The idea factory. When a company needs a campaign — the thought, the script, the look — it hires one of these shops and pays either a standing monthly fee or a price for the job.
This is the part under pressure. Clients are putting more of the budget into placing ads and less into making them, and there is a live question about whether AI tools eat into the fees for producing the work; the same squeeze is hitting rivals. Nobody here is betting the business on one customer: Omnicom's largest client is about two percent of revenue, handled by well over a hundred of the group's agencies.
Experiential & Other
Live events, sponsorship and sports marketing — stages, stands and deals with leagues. It grew over ten percent last quarter on World Cup work, but it is also where most of the businesses being sold off sit, and 2027 has no World Cup to match.
Competes with Publicis Live (Publicis Groupe) · IMG sponsorship (Endeavor) · Experiential units (Stagwell)
In plain English
Fan zones, trade-show stands, a brand's name on a tournament. Advertisers pay Omnicom to build and run the physical side of marketing — the stage, the booth, the arrangement with a league — and pay again for the crew who staff it. The 2026 World Cup made this the hot corner of the company last quarter.
It is also the messiest corner. Roughly half of what Omnicom is still selling off after the merger sits in this line: thin-margin work with patchy growth that management decided it did not want. So the number here shrinks by choice as much as by demand.
Omnicom Public Relations
FleishmanHillard, Weber Shandwick, Golin Ketchum and Porter Novelli — reputation, press and crisis work. About a ninth of revenue, growing at a mid-single-digit rate now that the 2025 election-cycle drag has passed.
Competes with Edelman (Edelman) · Burson (WPP) · MSL (Publicis Groupe)
In plain English
Reputation for hire. Companies pay these agencies to get talked about in the right way, and to steer the conversation when something goes wrong — a recall, a lawsuit, a bad week. Politicians and regulators are part of the audience, which is why election years move the numbers.
Fees arrive as a standing monthly charge plus project work, so this is a people-heavy business with nothing to carry and no event calendar to chase. The merger put two of the largest public-relations networks in one group, and management says that overlap will throw off more cost savings than the healthcare side does.
Omnicom Health
Marketing for drug makers — about a ninth of revenue and flat last quarter. The exposure is wider than the slice looks: pharma and health clients were the company's largest customer group, near a fifth of last quarter's revenue.
Competes with Publicis Health (Publicis Groupe) · Klick Health (Klick) · Inizio Evoke (Inizio)
In plain English
Drug advertising is a world of its own. A new medicine has to be explained to specialists at conferences, argued past the people who decide which treatments get paid for, and sometimes pitched to patients — all under strict rules on how medicines may be promoted. These agencies do that work, brand by brand, for steady monthly fees and one-off projects.
Growth has stalled; the line was flat last quarter, and it rises and falls with how many new drugs get approved and launched. The curious part is that health matters to Omnicom far more than this slice suggests, because the same pharma clients also buy media, creative and public relations from the rest of the group.
Flywheel Commerce Network
Bought in January 2024, it runs brands' selling on Amazon, Walmart and Target — product pages, the ads inside those stores, the daily fight for the top of the search results. Small, and now folded into Omni.
Competes with CitrusAd and Profitero (Publicis Groupe) · Retail-media software (Pacvue) · Retail media (Criteo)
In plain English
Shelf space, but online. When you search a big retailer's app for shampoo, the order of what you see is partly bought and partly earned. Brands hire Flywheel to work both sides: fix the product listings, bid for the sponsored slots, and watch what actually sells.
Brands pay management fees for that. Two years on it is a small line inside a much bigger company, and its Commerce Cloud has been absorbed into Omni as one pillar of the shared system rather than sold as a thing of its own — one reason it has all but vanished from the company's earnings calls.
