For the quarter ended 31 December, total revenue reached $5.5 billion, up 27.9% from the same period a year earlier, boosted in part by one month of IPG’s operations.

Media and advertising remained the largest contributor, accounting for around 60% of Q4 revenue, while precision marketing represented 10.3% and public relations 9.1%.

Despite strong top-line growth, Omnicom elected not to disclose organic revenue figures in its quarterly presentation.

CFO Phil Angelastro estimated that Q4 organic growth, based on historical standards and excluding planned dispositions, would have been approximately 4%.

The company also doubled its expected merger-related cost savings, up from $750 million.

CEO John Wren outlined the primary sources of the $1.5 billion target: $1 billion from labour cost reductions, $240 million from real estate consolidation, and $260 million from operational synergies in general administration, IT, procurement, and other functions.

The plan includes streamlining agency structures, eliminating duplicative roles, and accelerating outsourcing and offshoring initiatives.

Wren noted the expanded use of automation and artificial intelligence to improve operational efficiency and service delivery.

“Across every area of our business, we are evaluating and deploying automation and AI to improve how we service our clients and run our operations,” he said.

As part of its integration, Omnicom plans to divest or exit non-strategic businesses generating roughly $700 million in annual revenue.

While the move reinforces cost discipline, it raises questions about employee impact following prior layoffs and adjustments to benefits.

Wren reported largely positive client feedback regarding the merger, stating that enthusiasm for the combined company’s positioning has been widespread.

“Across the board, it’s far better than I fully expected,” he said, noting minimal negativity within the organisation.
