The initial redundancies represent a small portion of the workforce in Australia, with roughly a dozen roles cut locally; globally, about 4,000 redundancies are planned in this wave, under 4% of Omnicom’s staff, and a second wave in 2026 is expected to target centralised middle-office functions, notably in data, technology, and performance units, with substantial impact anticipated in the US.

The creative agency landscape is being reshaped: DDB Australia merges with Clemenger BBDO to form a single national agency, 303 MullenLowe rebrands as 303, and New Zealand entities cohere under McCann Group NZ, accompanied by leadership changes.

Notable leadership exits include IPG Mediabrands CEO Mark Coad, APAC chief Leigh Terry, chief investment officer Lucy Formosa Morgan, CFO John Clements, and Mediabrands Content Studio MD Harry Preston.

Omnicom has completed the first wave of redundancies and leadership reshuffles tied to the IPG Mediabrands takeover, with some decisions made before full consultation with IPG staff.

Across the Asia-Pacific region, Omnicom dominates leadership appointments, with about 85% of country heads and 90% of APAC leadership coming from Omnicom, while Japan remains led by IPG executives in key roles.

In Australia, Omnicom Media remains the dominant force and is consolidating brands, while several IPG Mediabrands leaders transition into new Omnicom roles and a number of IPG Mediabrands executives depart.

The integration aims for cultural clarity, a unified operating model, and transparent communication to drive client-focused integration and growth, while acknowledging inevitable redundancies and organizational shifts.

The takeover accelerates consolidation across Australia and Asia-Pacific, with Omnicom driving the momentum and shaping leadership appointments to favor its executives.

Omnicom Media brands are largely retained with no immediate plan to shrink the brand portfolio; speculation about Hearts & Science folding into UM is denied, and a full-year window is expected before any major media-brand structure changes.
