Revenue

Revenue in the first quarter of 2026 increased $2.6 billion to $6.2 billion as compared to the first quarter of 2025, primarily due to the acquisition of IPG, which closed on November 26, 2025, and constant currency revenue growth. The impact of foreign currency translation increased revenue by $174.2 million, or 4.8%. Revenue in the first quarter of 2026 includes $627.2 million from dispositions and assets held for sale.

Expenses

Operating expenses increased $2.4 billion to $5.6 billion in the first quarter of 2026 compared to the first quarter of 2025, primarily due to the acquisition of IPG. Included in operating expenses in the first quarter of 2026 are $59.4 million of integration and transaction costs related to the acquisition of IPG, $4.1 million of repositioning costs, and $34.3 million of loss on planned dispositions following the closing of the IPG acquisition.

Salary and service costs increased $1.9 billion to $4.6 billion, primarily due to the IPG acquisition and constant currency revenue growth. These costs tend to fluctuate with changes in revenue and are comprised of salary and related costs, which include employee compensation and benefits costs and freelance labor, third-party service costs, and third-party incidental costs. Salary and related costs increased $1.3 billion to $3.1 billion. Third-party service costs increased $568.9 million to $1.4 billion, primarily due to growth in our Integrated Media discipline and the effects of including a full quarter of IPG costs. Third-party incidental costs increased $43.3 million to $212.3 million, primarily due to revenue growth and the acquisition of IPG.

Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, increased $212.7 million to $527.3 million, primarily due to the acquisition of IPG.

SG&A expenses increased $106.6 million to $224.5 million, primarily due to the acquisition of IPG. Included in SG&A expenses in the first quarter of 2026 are $59.4 million of integration and transaction costs related to the acquisition of IPG.

Operating Income

Operating income increased $193.6 million to $646.2 million in the first quarter of 2026 compared to the first quarter of 2025, primarily as a result of the IPG acquisition, partially offset by costs primarily related to the integration of IPG.

Interest Expense, net

Net interest expense in the first quarter of 2026 increased $42.6 million to $72.0 million compared to the first quarter of 2025, primarily due to debt assumed as part of the IPG acquisition and the refinancing activities in the first quarter of 2026. Interest expense increased $59.9 million to $119.0 million. Interest income increased $17.3 million to $47.0 million.

Income Taxes

Our effective tax rate for the first quarter of 2026 was 26.9% compared to 28.5% for the first quarter of 2025. The effective tax rate for 2026 reflects the impacts of the lower tax benefit associated with integration costs, severance and repositioning charges related to the acquisition of IPG. Excluding these items, our Non-GAAP adjusted effective tax rate for the first quarter of 2026 was 26.0% compared to 26.7% for the first quarter of 2025.

Net Income – Omnicom Group Inc. and Diluted Net Income per Share

Net income - Omnicom Group Inc. for the first quarter of 2026 increased $117.5 million to $405.2 million compared to the first quarter of 2025. Weighted-average diluted shares outstanding for the first quarter of 2026 increased to 299.2 million from 198.3 million, primarily as a result of shares issued for the IPG acquisition, partially offset by net share repurchases, including shares purchased pursuant to the accelerated stock repurchase agreement. Diluted net income per share of $1.35 decreased by $0.10 from $1.45 in the prior year period.

Non-GAAP Adjusted Net Income per Share - Diluted for the first quarter of 2026 increased $0.20, or 11.8%, to $1.90 from $1.70. Non-GAAP Adjusted Net Income per Share - Diluted for the first quarters of 2026 and 2025 excluded $86.9 million and $16.1 million, respectively, of after-tax amortization expense. Non-GAAP Adjusted Net Income per Share - Diluted for the first quarter of 2026 also excluded $46.7 million of after-tax integration and transaction costs, $3.1 million of after-tax severance and repositioning costs and $27.8 million of loss on dispositions. In 2025, Non-GAAP Adjusted Net Income per Share - Diluted excluded $32.7 million of costs related to the acquisition of IPG. We present Non-GAAP Adjusted Net Income per Share - Diluted to allow for comparability with the prior year period.

EBITA

EBITA increased $289.2 million to $763.6 million in the first quarter of 2026 compared to the first quarter of 2025 and, in both periods, it included impacts from assets subsequently disposed of or currently held for sale. Adjusted EBITA increased $353.2 million, or 69.5%, to $861.4 million in the first quarter of 2026 compared to the first quarter of 2025, and the related margin stayed flat at 13.8%. EBITA and Adjusted EBITA excluded amortization expense of $117.4 million and $21.8 million in the first quarters of 2026 and 2025, respectively. Adjusted EBITA also excluded $59.4 million of costs related to the integration of IPG, severance and repositioning costs of $4.1 million, and a loss on dispositions of $34.3 million in the first quarter of 2026. Adjusted EBITA in the first quarter of 2025 also excluded $33.8 million of costs related to the acquisition of IPG.

Risks and Uncertainties

Global economic conditions and disruptions, including geopolitical events, international hostilities, acts of terrorism, public health crises, inflation or stagflation, tariffs and other trade barriers, central bank interest rate policies in countries that comprise our major markets, labor and supply chain issues affecting the distribution of our clients' products, or a disruption in the credit markets could cause economic uncertainty and volatility. The impact of these issues on our business will vary by geographic market and discipline. We monitor economic conditions and disruptions closely, as well as client revenue levels and other factors. In response to reductions in revenue, we can take actions to align our cost structure with changes in client demand and manage our working capital. However, there can be no assurance as to the effectiveness of our efforts to mitigate any impact of the current and future adverse economic conditions and disruptions, reductions in client revenue, changes in client creditworthiness and other developments.

Definitions - Components of Revenue Change

We use certain terms in describing the components of the change in revenue above.

Core Operations: Revenue from Core Operations excludes businesses that have been disposed of or are classified as held for sale. Amounts for 2025 are calculated on a combined basis for Omnicom and IPG.

Organic growth: calculated by subtracting the foreign exchange rate impact from total revenue growth, which is equal to the current period revenue from Core Operations minus the prior period revenue from Core Operations.

Foreign exchange rate impact on core operations: calculated by translating the current period's local currency revenue using the prior period average exchange rates to derive current period constant currency revenue. The foreign exchange rate impact is the difference between the current period revenue in U.S. Dollars and the current period constant currency revenue.

Percentage change: Calculated by dividing the individual component amount by the prior period Core Operations revenue base.

Conference Call

Omnicom will host a conference call to review its financial results on April 28, 2026 starting at 4:30 p.m. Eastern Time. A live webcast of the call, along with the related slide presentation, will be available at Omnicom's investor relations website, investor.omc.com, and a webcast replay will be made available after the call concludes.

Non-GAAP Financial Measures

We present financial measures determined in accordance with generally accepted accounting principles in the United States ("GAAP") and adjustments to the GAAP presentation ("Non-GAAP"), which we believe are meaningful for understanding our performance. We believe these measures are useful in evaluating the impact of certain items on operating performance and allow for comparability between reporting periods. We define EBITA as earnings before interest, taxes, and amortization, principally of acquired intangible assets and internally developed strategic platform assets, and EBITA margin is defined as EBITA divided by revenue. We use EBITA and EBITA margin as additional operating performance measures, which exclude the non-cash amortization expense principally from acquired intangible assets and internally developed strategic platform assets. We also use Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted EBITA, Adjusted EBITA Margin, Adjusted Income Tax Expense, Adjusted Net Income – Omnicom Group Inc., Adjusted Net Income per share – Omnicom Group Inc. - Diluted, and organic growth as additional operating performance measures. For 2025, we also used Combined Adjusted EBITA, which was calculated using the combined adjusted EBITA of Omnicom and IPG. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in accordance with GAAP. Non-GAAP financial measures as reported by us may not be comparable to similarly titled amounts reported by other companies.

1)	See Note 3 on page 13.
2)	Adjusted Net Income per Share - Diluted for the three months ended March 31, 2026 excludes after-tax amortization expense principally from acquired intangible assets and internally developed strategic platform assets, after-tax severance and repositioning costs, after-tax loss on disposition of subsidiaries and after-tax integration costs related to the acquisition of IPG. We believe these measures are useful in evaluating the impact of these items on operating performance and allow for comparability between reporting periods. Adjusted Net Income per Share - Diluted for the three months ended March 31, 2025 excludes after-tax amortization expense principally from acquired intangible assets and internally developed strategic platform assets and after-tax integration costs related to the acquisition of IPG.
3)	Weighted-average diluted shares for the three months ended March 31, 2026 and 2025 were 299.2 million and 198.3 million, respectively. The above tables reconcile the Non-GAAP financial measures of Non-GAAP Operating Income - Adjusted, Non-GAAP Net Income-Omnicom Group Inc. - Adjusted and Non-GAAP Adjusted Net Income per Share - Diluted to the GAAP financial measures of Operating Income, Net Income - Omnicom Group Inc. and Net Income per Share - Diluted. Management believes these Non-GAAP measures are useful for investors to evaluate the comparability of the performance of our business year to year.
