The news: Agency holding companies are navigating a changing market. H1 results showed a widening gap in company performance, with Publicis and Omnicom delivering stronger growth as they leaned into integrated, AI-first approaches, while Dentsu and WPP remained focused on restructuring and profitability.

• Omnicom’s H1 revenues hit $12.8 billion, up from $7.7 billion in H1 2025.
• Publicis’ H1 organic net revenues grew 4.7% to €7.2 billion ($8.1 billion).
• Japan-based holdco Dentsu reported H1 net revenue growth of 3.7% to ¥583.1 billion ($3.8 billion), with organic growth of just 0.3%.
• Havas’ H1 revenues grew 0.6% to €1.42 billion ($1.6 billion).
• WPP’s H1 revenues fell -4.4% YoY, the only negative growth out of the listed holdcos, but an improvement from a -7.8% loss a year earlier.

Behind the numbers: Holdcos are using different levers—from AI and acquisitions to restructuring and consolidation—to build broader, more efficient agency models.

• Omnicom extended its growth streak, helped in part by its late-2025 IPG acquisition, with success also coming from its integrated media solution that spans media buying, commerce services, data analytics, and content automation. This offering accounted for 52.5% of Omnicom’s core operations revenues, showing how bundled services have become central to the holdco model.
• AI innovation and strategic acquisitions fueled Publicis’ H1 performance, with AI solutions accounting for 87% of Q2 net revenues. That suggests AI is becoming embedded in the holdco's core revenue model, rather than being a standalone capability.
• Dentsu is taking a more defensive approach, combining investment in technology, data, AI, and media operations with job cuts and a goal of having “no markets operating at a loss” by the end of 2027. Its planned “AI-native operating model” shows that restructuring and AI adoption are increasingly intertwined.
• Havas’ H1 earnings suggested that future growth will depend in part on expanding its agency portfolio. The holdco made acquisitions across sports, experiential marketing, and social media to build a broader portfolio of capabilities.
• WPP’s Elevate28 turnaround plan helped narrow the company’s losses, with the phased strategy kicking off in Q2 through WPP Commerce. The newly merged team brings together the company’s media, creative, production, and enterprise solutions.

Why it matters: The earnings point to an agency landscape where the holdcos best positioned to compete will be those that can turn a broad range of capabilities into simpler client relationships and more efficient delivery.

Those strategies also address persistent operational challenges within agencies: 44.1% of agency professionals worldwide struggle with inefficient processes, while 40.4% cite siloed and disconnected systems, per Basis.

Implications for marketers: H1 results suggest that holdcos that can simplify and automate complex processes will be better positioned to compete, aided by strategic acquisitions, AI investment, and broader capabilities. For marketers, that could mean less complexity in managing agency relationships, faster access to specialized capabilities, and more efficient delivery across increasingly fragmented marketing needs.
