The news: Omnicom’s first earnings report since closing its acquisition of Interpublic Group offers an early look at the scale of the combined company—and the integration work ahead.

Revenue growth reflects deal-driven expansion, while management is emphasizing cost discipline and structural consolidation to drive returns.

• Q4 2025 revenues reached $5.5 billion, up 27.9% YoY, reflecting the late-November close of the IPG acquisition.
• Full-year revenues totaled $17.3 billion, up 10.1% from 2024, with one month of IPG results included.
• CFO Phil Angelastro said organic growth for retained businesses was about 4% in Q4, excluding roughly $2.5 billion in revenues from assets slated for divestiture and $700 million tied to minority-stake reductions.
• Management doubled its cost-savings target to $1.5 billion over 30 months, with about $900 million expected in 2026; roughly $1 billion will come from future job cuts, with the remainder from operational streamlining and real estate consolidation.

Why it matters: The results highlight a broader industry tension: Holdco scale is increasing, but revenue growth is lagging behind media expansion.

• Since 2023, overall growth in media ad spending has outpaced average holding company revenue growth; media is projected to rise 8.6% in 2025 while holding company revenues decline 1.2%, per our forecast and company earnings reports.
• Consolidation accelerated from 2023 to 2025, culminating in the Omnicom–IPG merger. Other transactions include WPP’s acquisition of New Commercial Arts and Publicis’ formation of Leo.
