Let me quickly compute a couple of stock performance figures before writing.# Omnicom Group (OMC) — Q2 2026 Earnings Preview
This is only Omnicom's second full quarter as the "new Omnicom" following the November 26, 2025 close of the ~$13B Interpublic (IPG) acquisition. The report is less about a single EPS print and more about proving that the integration thesis — cost synergies, portfolio pruning, and a bigger, more data/media-weighted platform — is actually compounding. Management set an aggressive tone last quarter, explicitly aiming to deliver profitability and earnings-per-share growth that will set a new standard for our sector.
Because year-ago numbers are distorted by the merger, the reported growth rate is close to meaningless. The figures that matter are core-operations organic growth and adjusted EBITA margin, both of which management now reports on a combined-basis comparison.
Last quarter, revenue from core operations was $5.6 billion in the first quarter, which increased $345 million when compared to Q1 2025 revenue from core operations for the combined Omnicom and Interpublic. Organic revenue growth was 3.9%. Management reaffirmed a full-year ~4% constant-currency core organic target at its Investor Day and said it remains on track. Watch whether Q2 accelerates toward/above 4% — a re-acceleration would be an important sign that client losses from the merger aren't materializing.
By discipline in Q1: Integrated Media led the way with very strong growth in the high single digits. PR and experiential and other grew in the quarter mid-single digits. Health had positive growth and advertising was down in Q1. The advertising (creative) softness is the key watch item — management framed it partly as a mix shift toward automated production inside Integrated Media, but a second consecutive decline would draw scrutiny. Integrated Media is now the anchor of the story: Revenue from our core operations in the first quarter of 2026 for Integrated Media was approximately 52% of our revenues. And for advertising was 17% Health, 10%; PR 12%; and Experiential & Other, 10%.
The bull case rests on cost synergies flowing to the bottom line. In Q1, adjusted EBITDA margin increased 240 basis points to 14.8% as compared to the combined operations for Q1 2025, driven primarily by synergies. Management is targeting $900 million in 2026 cost reduction synergies and $1.5 billion by mid-2028, having already merged or sunset more than 20 major agency brands. Look for margin to expand again and for any raise/refinement to the synergy pace.
Omnicom is shedding roughly $3.2 billion of annual revenue, of which approximately $1 billion was disposed of in the first quarter, with the rest targeted for sale/exit "over the next several quarters." Two nuances flagged last quarter: - Management conceded the held-for-sale margins are below the ~10% earlier guided: It turns out that the margins of these businesses are probably not 10%. They're probably something less. - Proceeds are hard to model; the first big sale (Jack Morton) generated cash but management cautioned it will generate additional cash rather than materially boost net income. Progress on clearing this "noise" is a sentiment positive since it clarifies the go-forward earnings power.
This is a core part of the EPS-growth engine. Omnicom is running a $5 billion in share repurchases over the next 12 months, including a $2.5 billion accelerated share repurchase program, and had already repurchased $2.8 billion of shares through the first quarter. Management guided that share count decline approximately 11% to 12% by December 31, 2026, and that weighted average shares outstanding for the year will decline approximately 8% to 9%. The dividend was also raised (~14% to $0.80/quarter). Expect buyback pace to be a meaningful EPS tailwind in Q2.
Management was unusually pointed about the back half. On EPS growth after Q1's ~11.8%: we expect probably the quarters as they roll out are going to be higher double digits than the first quarter performance. That framing is why consensus has Q2 growth near ~29%. The risk is that expectations are now elevated — a mere in-line print may underwhelm given the setup.
OMC has been a choppy but net-positive performer since the deal closed: shares are roughly flat YTD (~+2%) at ~$82, but up ~21% off the early-February low near $68. Notably, the Q4 2025 report drove a ~15% single-day pop, showing how sensitive the stock is to integration/margin data points. The read-across from struggling peer WPP (near multi-year lows) versus a steadier Publicis frames the debate: is Omnicom's scale-plus-data model taking share, or is the whole traditional-agency complex under structural AI pressure?
A "good" quarter looks like: core organic growth at/above ~4% (with advertising stabilizing), another leg of margin expansion from synergies, continued buyback-driven share-count reduction, visible progress on dispositions, and management reiterating or nudging up the "higher double-digit" EPS-growth framing. The bar is not trivial — consensus already embeds ~29% adjusted EPS growth — so the risk skews toward "beat-and-hold" unless organic acceleration or a synergy raise gives the market something genuinely new. Given the merger noise, treat headline reported growth as cosmetic and anchor on the core-operations disclosures.
