SEC filingOmnicom reported Q1 2026 revenue of $6.2 billion and GAAP diluted EPS of $1.35, with Non-GAAP adjusted diluted EPS of $1.90, up 11.8% year-over-year.
Omnicom's first quarter 2026 results reflect the initial impact of the transformative acquisition of Interpublic Group (IPG), which closed on November 26, 2025. Reported revenue surged to $6.2 billion from $3.7 billion a year ago, largely due to the inclusion of IPG's operations. On a pro-forma combined basis, Core Operations (excluding dispositions and held-for-sale businesses) generated $5.6 billion in revenue, up 6.7% year-over-year, with organic growth of 3.9%. The organic growth was driven by strength in Integrated Media (51.5% of Core revenue) and new client wins, partially offset by declines in Advertising and Experiential. Geographically, the United States contributed 61.4% of Core revenue, while Europe and Asia Pacific also showed solid performance.
Profitability improved significantly, with Core Operations Adjusted EBITA rising 27.3% to $833.5 million, and the margin expanding 240 basis points to 14.8%. This margin expansion was primarily attributed to cost reduction synergies from the IPG integration. On a reported GAAP basis, operating income was $646.2 million, including $97.8 million in non-GAAP adjustments (severance, repositioning, loss on dispositions, and acquisition-related costs). Adjusted EBITA (reported) reached $861.4 million, with a margin of 13.8%, flat year-over-year. Non-GAAP adjusted diluted EPS grew 11.8% to $1.90, benefiting from lower share count due to aggressive buybacks.
Management highlighted the successful launch of the Omni platform, integrating Acxiom's data and identity solutions, and noted that the company is on track to achieve its cost reduction synergy targets. The company also executed $2.8 billion in share repurchases during the quarter under a $5 billion authorization, with $2.2 billion remaining. Net debt stood at $5.7 billion as of March 31, 2026, with a pro-forma net debt to adjusted EBITDA ratio of 1.4x. Overall, the quarter demonstrates strong operational momentum and disciplined capital allocation, positioning Omnicom for enhanced profitability and earnings growth.
