Agency Report 2026: Omnicom Tops Rankings After Merger
Ad Age’s 2026 Agency Report shows Omnicom reclaimed the No. 1 agency ranking after acquiring Interpublic Group of Cos., highlighting consolidation at the top of the industry. The report also signals a broader shift: legacy holding companies now hold a smaller share of top-25 agency revenue even as Omnicom rose to the top. Related coverage called out AI hype and reflected client-side moves such as Procter & Gamble’s emphasis on a human-plus-AI approach and a modular agency model.
Omnicom Plans Major Cuts to Boost Post-Merger Synergies
Omnicom reported its full-year 2025 results — its first financial disclosure since completing the acquisition of Interpublic Group — but metrics are limited because Omnicom only owned IPG businesses for the final month. CEO John Wren said the merger’s annual run‑rate synergies are now expected to reach $1.5 billion over 30 months (up from $750 million), with roughly $1 billion from labour-cost reductions and $500 million from structural streamlining including outsourcing and offshoring. CFO Philip Angelastro flagged facility management, shared services and technology as likely areas affected. Omnicom has identified moves to reduce stakes in smaller markets (~$700 million) and plans sales/exits of non-strategic operations representing about $2.5 billion in annual revenue (around $800 million already sold/exited). The group expects media to represent a mid‑50s share of revenue and creative just under 20%. Executives say AI is expanding output and testing scale but is not currently expected to directly reduce headcount, though client savings and remuneration models may change.
Omnicom Stock Rises Amid IPG Sell-Off, Weak Q2 Ads
Omnicom reported roughly $6.6 billion in combined Q2 revenue and a jump in net income to $585 million, even as advertising revenue declined low single digits. Investors reacted positively after Omnicom outlined a program to sell off lower-growth IPG agencies and absorb selected assets, a strategy the company says will improve operating margins. Executives also addressed growth in "principal media" — agencies buying media inventory directly and passing it through — noting a material increase in third-party service costs tied to pass-through activity. The Q&A included questions from analysts about whether recent profit gains are sustainable beyond one-time benefits from dispositions.
