TLDR
Omnicom plans to cut 15,000 roles globally by the end of 2026, one in eight of its combined 120,000-person workforce. The reductions target duplicate back-office functions and sit on top of more than 8,000 roles already shed before the deal closed.
KEY TAKEAWAYS
One in eight jobs gone by Christmas
Omnicom Group plans to eliminate 15,000 positions by the end of 2026 as it absorbs Interpublic Group, the $13.5 billion acquisition that closed on 26 November 2025 and made Omnicom the world's largest marketing holding company. The combined entity employed approximately 120,000 people as at 31 December 2025, so the planned cuts amount to roughly one in every eight staff members.[1]
The reductions are concentrated in overlapping back-office and support functions across both legacy businesses. They sit separately from the $786 million restructuring charge Omnicom had already disclosed in its financial statements.
The savings timetable
At Omnicom's Investor Day on 12 March 2026, CFO Philip Angelastro outlined the programme. Angelastro said the synergy target is $1.5 billion in cost reductions by mid-2028, with $900 million of that falling in 2026 and $1.3 billion by end of 2027.[2] CEO John Wren kept it shorter: Wren said the company is confident it will hit the expected cost reductions in 2026.[2]
Omnicom's board doubled the total cost synergy target to $1.5 billion when it reported full-year 2025 results in February.[4] The mechanisms include offshoring, automation and real-estate consolidation alongside the headcount reductions. That $900 million 2026 target works out to roughly $60,000 in annualised savings per role cut, assuming the 15,000 reductions land evenly across the year.
The cuts before the cuts
The 15,000 figure is the new number, but it lands on top of a toll that was already steep. During 2024, while regulators reviewed the merger, Omnicom cut more than 3,000 roles and IPG reduced its headcount by 2,300, according to filings submitted to the US Federal Trade Commission in June 2025.[3] Add those pre-merger losses to the 15,000 planned and the combined toll across both companies exceeds 20,000 roles.
That makes this the largest single headcount reduction programme in advertising holding-company history, at least by the numbers on record. WPP's restructuring between 2018 and 2020 shed around 6,000 roles globally over two years, for comparison.
What it means for Australia and New Zealand
The Australian Competition and Consumer Commission cleared the Omnicom-IPG merger for the local market, and Omnicom has said it expects minimal immediate impact on ANZ operations. ANZ offices will participate in the efficiency programme, but the company has not disclosed a specific headcount figure for the region.
Both Omnicom and IPG run substantial operations in Australia across media buying, creative, PR and specialist agencies serving major domestic and multinational advertisers. When account teams shrink, service continuity becomes a practical question for clients, not just a structural one for the holding company.
Omnicom has been careful to say the reductions target duplicate administrative and support functions rather than creative or client-facing roles. Whether that distinction holds as the programme runs through 2026 is the number worth watching. Omnicom's next earnings call will provide the first hard update on progress against the $900 million 2026 savings target.
