Revenue
Revenue in the third quarter of 2025 increased $154.5 million, or 4.0%, to $4,037.1 million as compared to the third quarter of 2024. Worldwide revenue growth in the third quarter of 2025 compared to the third quarter of 2024 was led by an increase in organic revenue of $102.4 million, or 2.6%. Acquisition revenue, net of disposition revenue, was not significant. The impact of foreign currency translation increased revenue by $52.4 million, or 1.4%.

Organic growth by discipline in the third quarter of 2025 compared to the third quarter of 2024 was as follows: 9.1% for Media & Advertising, 2.0% for Execution & Support, and 0.8% for Precision Marketing, partially offset by declines of 1.9% for Healthcare, 7.5% for Public Relations, 17.7% for Experiential and 16.9% for Branding & Retail Commerce.

Organic growth by region in the third quarter of 2025 compared to the third quarter of 2024 was as follows: 4.6% for the United States, 27.3% for Latin America, 3.7% for the United Kingdom, and 5.9% for the Middle East & Africa, partially offset by declines of 0.2% for Other North America, 3.7% for Asia Pacific, and 3.1% for Euro Markets & Other Europe.

Expenses
Operating expenses increased $224.5 million, or 6.8%, to $3,507.0 million in the third quarter of 2025 compared to the third quarter of 2024. Included in operating expenses in the third quarter of 2025 are $60.8 million of acquisition related costs for the pending acquisition of The Interpublic Group of Companies, Inc. (“IPG”) and $38.6 million of repositioning costs, primarily related to severance as we prepare to integrate the pending acquisition of IPG.

Salary and service costs increased $125.5 million, or 4.5%, to $2,921.5 million. 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 decreased $68.4 million, or 3.7%, to $1,778.5 million, primarily due to our prior repositioning actions and changes in our global employee mix. As a percentage of revenue, salary and related costs decreased as compared to the prior period. Third-party service costs include third-party supplier costs when we act as principal in providing services to our clients. Third-party incidental costs that are required to be included in revenue primarily consist of client-related travel and incidental out-of-pocket costs, which are billed back to the client directly at our cost. Third-party service costs increased $171.1 million, or 21.8%, to $955.6 million, primarily as a result of organic growth in our Media & Advertising and Execution & Support disciplines. Third-party incidental costs increased $22.8 million, or 13.9%, to $187.4 million, primarily as a result of organic growth.

Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, decreased $2.9 million, or 0.9%, to $322.7 million. In the third quarter of 2025, as a percentage of revenue, occupancy and other costs decreased as compared to the prior period.

SG&A expenses increased $64.0 million, or 64.3%, to $163.5 million. Included in SG&A expenses in the third quarter of 2025 are $60.8 million of cost related to the pending acquisition of IPG.

Operating Income
Operating income decreased $70.0 million, or 11.7%, to $530.1 million in the third quarter of 2025 compared to the third quarter of 2024, and the related margin decreased to 13.1% from 15.5%. Acquisition related costs and repositioning costs related to the pending acquisition of IPG decreased operating margin by 2.4 percentage points in the third quarter of 2025.

Interest Expense, net
Net interest expense in the third quarter of 2025 increased $2.8 million to $43.2 million compared to the third quarter of 2024. Interest expense decreased $6.0 million to $60.4 million. Interest income decreased $8.8 million to $17.2 million, primarily due to lower average cash balances and lower interest rates.

Income Taxes
Our effective tax rate for the third quarter of 2025 increased to 27.2% compared to 26.8% for the third quarter of 2024. The effective tax rate for 2025 increased primarily due to the non-deductibility of certain acquisition related costs in 2025.

Net Income – Omnicom Group Inc. and Diluted Net Income per Share
Net income – Omnicom Group Inc. for the third quarter of 2025 decreased $44.6 million, or 11.6%, to $341.3 million compared to the third quarter of 2024. Diluted shares outstanding for the third quarter of 2025 decreased 1.7% to 194.9 million from 198.2 million as a result of net share repurchases. Diluted net income per share of $1.75 decreased $0.20, or 10.3%, from $1.95. Non-GAAP Adjusted Net Income per Share – Diluted for the third quarter of 2025 increased $0.21, or 10.3%, to $2.24 from $2.03. Non-GAAP Adjusted Net Income per Share – Diluted for the third quarters of 2025 and 2024 excluded $15.9 million and $16.4 million, respectively, of after-tax amortization of acquired intangible assets and internally developed strategic platform assets. Non-GAAP Adjusted Net Income per Share – Diluted for the third quarter of 2025 also excluded $50.8 million of after-tax acquisition related costs and $28.4 million of after-tax repositioning costs. We present Non-GAAP Adjusted Net Income per Share – Diluted to allow for comparability with the prior year period.

EBITA
EBITA decreased $70.7 million, or 11.4%, to $551.6 million in the third quarter of 2025 compared to the third quarter of 2024, and the related margin decreased to 13.7% from 16.0%. Adjusted EBITA increased $28.7 million, or 4.6%, to $651.0 million in the third quarter of 2025 compared to the third quarter of 2024, and the related margin increased to 16.1% from 16.0%. EBITA and Adjusted EBITA excluded amortization of acquired intangible assets and internally developed strategic platform assets of $21.5 million and $22.2 million in the third quarters of 2025 and 2024, respectively. Adjusted EBITA also excluded $60.8 million of costs related to the pending acquisition of IPG and repositioning costs of $38.6 million in the third quarter of 2025.

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.

Foreign exchange rate impact: 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.

Acquisition revenue, net of disposition revenue: Acquisition revenue is calculated as if the acquisition occurred twelve months prior to the acquisition date by aggregating the comparable prior period revenue of acquisitions through the acquisition date. As a result, acquisition revenue excludes the positive or negative difference between our current period revenue subsequent to the acquisition date, and the comparable prior period revenue and the positive or negative growth after the acquisition date is attributed to organic growth. Disposition revenue is calculated as if the disposition occurred twelve months prior to the disposition date by aggregating the comparable prior period revenue of disposals through such date. The acquisition revenue and disposition revenue amounts are netted in the description above.

Organic growth: calculated by subtracting the foreign exchange rate impact component and the acquisition revenue, net of disposition revenue component from total revenue growth.

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 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 of 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. and Adjusted Net Income per share – Omnicom Group Inc. – Diluted as additional operating performance measures. 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.

risks related to environmental, social and governance goals and initiatives, including impacts from regulators and other stakeholders, and the impact of factors outside of our control on such goals and initiatives.

The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that may affect the Company’s business, including those described in Item 1A, “Risk Factors” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K and in other documents filed from time to time with the Securities and Exchange Commission.

2) Adjusted Net Income per Share – Diluted for the three and nine months ended September 30, 2025 excludes after-tax amortization of acquired intangible assets and internally developed strategic platform assets, after-tax repositioning costs, and after-tax acquisition related costs.
