Omnicom’s third-quarter growth beats expectations, but margin falls short: Barclays cuts earnings forecasts

Why did third-quarter growth and profit diverge?

Omnicom’s core business posted organic revenue growth of 7.2% in the third quarter, above the Bloomberg consensus of 4.4%; this measure excludes weaker businesses held for sale. Total company revenue fell 1.7% year on year to 6.423 billion dollars, still above market expectations.
The adjusted EBITA margin was 17.6%, below the consensus of 18.5%; adjusted earnings per share were 2.73 dollars, broadly in line with the consensus of 2.72 dollars.
Integrated media accounted for approximately 53% of core business revenue and grew organically by more than 10%; advertising revenue declined by a mid-single-digit percentage. Barclays estimates that World Cup-related experiential business lifted quarterly organic growth by approximately 1.5 percentage points, while the company expects that business to stop growing in the fourth quarter.

Barclays forecasts organic growth of 5.5% in core business gross revenue in 2026, but its model puts organic net revenue growth at approximately 1.5% after costs passed through to third parties. The bank believes the gap has widened from approximately 2 percentage points in recent years to approximately 4 percentage points, potentially reflecting Interpublic’s media-buying practices moving closer to Omnicom’s.
The company expects to achieve 900 million dollars in cost synergies in 2026, with 75%–80% converting into EBITA growth and margin improvement. By Barclays’ calculations, core business EBITA was approximately 3.49 billion dollars in 2025; adding those synergies brings it close to the bank’s 2026 forecast of 4.224 billion dollars, leaving little additional profit contribution from revenue growth.
The bank believes slower net revenue growth helps explain this: if the synergy conversion rate reaches 75%, incremental revenue after pass-through costs and foreign-exchange gains would need to generate an incremental EBITA margin of approximately 11%, below the core business margin of 15.3% in 2025.

The company raised its 2026 organic revenue growth guidance for the continuing core business from 4.5%–5.0% to approximately 5.0%. Barclays raised its own forecast from 4.7% to 5.5% and expects fourth-quarter growth of 4.8%.
Alongside the higher growth forecast, Barclays cut its adjusted earnings-per-share forecast for 2026 by 6.3% to 10.30 dollars and its 2027 forecast by 8.9% to 10.99 dollars, citing a greater drag from divestitures and less conversion of synergy benefits into profit.
The businesses held for sale represented approximately 3.6 billion dollars in prior-year annualized revenue and had an adjusted EBITA margin of approximately 11%–12% last year; the company aims to complete the transactions by the end of 2026, although some may be delayed until early 2027.

Barclays cut its forecast for the overall adjusted EBITA margin in 2028 from 19.5% to 17.9%; on a comparable basis, that forecast remains above Publicis’s 15.6%. The company’s three-year cost synergy target is 1.5 billion dollars, approximately two-thirds of which comes from personnel cost reductions.
The stock trades at approximately 8 times Barclays’ 2026 earnings forecast, but the bank believes uncertainty remains over medium-term margins, further divestitures and AI’s impact on agency fees. Barclays maintained its Equal Weight rating and cut its price target from 88 dollars to 87 dollars.
