Omnicom Plans to Merge Mediahub and Hearts & Science Into a 40-Market Network
Omnicom has announced plans to combine Mediahub and Hearts & Science into a single global media-agency network with approximately $9.1 billion in 2025 billings, though the merger is not yet complete. Several regional leaders have been named, but the network's brand identity and leadership for APAC and Latin America remain unresolved until an expected late-August launch. The consolidation is part of Omnicom's broader integration of Interpublic Group, under which it has doubled its three-year cost-synergy target to $1.5 billion.
