Omnicom's businesses grew 7.2 per cent organically in the third quarter of 2026, the fastest pace since it bought Interpublic, and adjusted earnings rose 22 per cent to $2.73 a share, the company said in its third-quarter earnings release on 22 October. Reported revenue rose 59 per cent to $6.42 billion, which is mostly the merger.
The deal closed on 26 November 2025. The growth number is the one investors were waiting for. The balance sheet is where the cost of the year shows.
Is the merged company actually growing?
Yes, on the company's own measure, and faster each quarter. Omnicom reports "core operations," which strip out businesses it has sold or plans to sell and compare against a combined Omnicom-plus-Interpublic figure for 2025. On that basis revenue was $6.01 billion, up 7.3 per cent, with organic growth of $400.8 million, or 7.2 per cent. Its investor presentation shows organic growth of 3.9 per cent in the first quarter and 6.1 per cent in the second. For nine months it is 5.8 per cent.

Integrated media, the buying and planning of advertising, is 53 per cent of core revenue at $3.2 billion. The United States is 60 per cent. The company does not break organic growth out by discipline or region, so it is not possible from the filings to say which units are carrying the number.
John Wren, chairman and chief executive, said in the release that Omnicom is "on track to deliver $900 million in cost-reduction synergies in 2026" and is "well positioned to pursue future growth." The margin improvement is consistent with that. The release attributes it to cost synergies and business performance, and does not say how much of the $900 million has been booked so far.
What did the merger cost this quarter?
About $125 million in charges, plus the price of carrying more debt. Repositioning costs, mainly real estate and exit charges, were $84.7 million, and integration and transaction costs were $40.4 million. Amortization of acquired intangibles rose to $120.1 million from $21.5 million. Net interest expense rose $61.0 million to $104.2 million, which the release attributes to Interpublic's debt and a refinancing in the first quarter. A $106.8 million gain on selling a subsidiary offset most of the charges.
Where did the buyback money come from?
Partly from borrowing. Omnicom repurchased $3.21 billion of stock in the first nine months, against $312.1 million a year earlier, under a $5 billion authorization the board approved in February. About $2.5 billion of that was an accelerated repurchase that settled in May, according to the Form 10-Q. Stand-alone free cash flow for the nine months was $2.35 billion. By this publication's arithmetic, buybacks alone exceeded it by $857 million, before $703.3 million of dividends.
Net debt was $6.22 billion at 30 September, up from $2.89 billion a year earlier. In March Omnicom sold $1.7 billion of dollar bonds due 2029, 2033 and 2036 and €600 million of notes due 2034, and used part of the proceeds to repay $1.4 billion of notes due this year.
The leverage ratio depends on which earnings you use. On trailing reported EBITDA, which includes Interpublic for only part of the period, net debt is 2.9 times earnings, against 1.2 times a year ago. On pro forma adjusted EBITDA, which counts a full year of both companies, it is 1.4 times, the presentation shows. The second figure is the fairer description of the combined business. The first is what a lender looking at reported numbers would see until the merger is a full year old.
The buyback has a plain purpose. Omnicom paid for Interpublic in stock, and the diluted share count rose 41 per cent. Buying shares back offsets some of that dilution. That is our reading; the company does not describe the program that way.
Details to note
The portfolio clean-up is "substantially complete," the presentation says, with a few disposals still to close and $413.9 million of proceeds from assets held for sale this year. Businesses sold or held for sale brought in $412.1 million of revenue in the quarter, which is why reported and core figures differ.
No client is large. The biggest was 1.8 per cent of revenue over the past twelve months and the top 100 were 52.7 per cent, the 10-Q says. The filing also says "Generative AI and agentic AI have, and we believe will continue to have, a significant impact" on how its services are delivered, a risk for a business paid partly for labor as automated buying spreads among advertisers.
The release and presentation contain no formal financial guidance.
What to watch
The fourth quarter brings the first reported comparison that includes Interpublic in the prior year, for the five weeks after the November 2025 closing. If organic growth holds above 6 per cent once synergy savings stop flattering the margin comparison, the merger is working on its own terms. If net debt keeps rising while buybacks continue, the test becomes whether the board slows repurchases in 2027.
