REVENUE CHANGE Core Operations Notes: (1) 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. (2) 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. (3) 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. (4) The percentage change is calculated by dividing the individual component amount by the prior period Core Operations revenue base.

11 NOTES (a) For the three months ended March 31, 2026, operating expenses included $4.1 million ($3.1 million after-tax) of repositioning costs, primarily related to severance actions in connection with the merger (the "Merger") with IPG and $34.3 million ($27.8 million after-tax) of losses on dispositions of certain businesses in connection with the Merger. In addition, included in selling, general and administrative expenses for the three months ended March 31, 2026 are integration and transaction costs related to the acquisition of IPG of $59.4 million ($46.7 million after-tax). The net impact of these items reduced operating income for the three months ended March 31, 2026 by $97.8 million ($77.6 million after-tax), which reduced diluted net income per share - Omnicom Group Inc. by $0.26. Included in selling, general and administrative expenses for the three months ended March 31, 2025 are acquisition-related expenses of $33.8 million ($32.7 million after-tax) in connection with the Merger with IPG, which reduced diluted net income per share - Omnicom Group Inc. by $0.17. (b) Our effective tax rate for the first quarter of 2026 was 26.9% compared to 28.5% for the first quarter of 2025.Income tax expense for the three months ended March 31, 2026 included impacts of the severance and other repositioning costs, losses on dispositions of certain business and integration and acquisition-related costs. Income tax expense for the three months ended March 31, 2025 included impacts related to real estate and other repositioning costs. (c) Third-party service costs include third-party supplier costs when we act as principal in providing services to our clients. (d) Third-party incidental costs primarily consist of client-related travel and incidental out-of-pocket costs, which we bill back to the client directly at our cost and which we are required to include in revenue. Financial Notes Definitions (1) Core operations, net of dispositions and held for sale: calculated from the combined revenue, adjusted operating income and adjusted EBITA of the Company, excluding 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. (2) 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. (3) 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. (4) The percentage change is calculated by dividing the individual component amount by the prior period Core Operations revenue base.

The call will be archived on the internet at http://investor.omc.com Forward-Looking Statements Certain statements in this document contain forward-looking statements, including statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. In addition, from time to time, we or our representatives have made, or may make, forward-looking statements, orally or in writing. These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of management as well as assumptions made by, and information currently available to management. Forward-looking statements may be accompanied by words such as “aim”, “anticipate”, “believe”, “plan”, “could”, “should”, “would”, “estimate”, “expect”, “forecast”, “future”, “guidance”, “intend”, “may”, “will”, “possible”, “potential”, “predict”, “project” or similar words, phrases or expressions. These forward-looking statements are subject to various risks and uncertainties, many of which are outside of our control. Therefore, you should not place undue reliance on such statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include: risks relating to the completed merger (the “Merger”) between us and The Interpublic Group of Companies, Inc. ("IPG"), including risks related to the integration of IPG’s business, such as, among others: uncertainties associated with retaining key management and other employees; potential disruptions to client, vendor, and business partner relationships; the risk that integration activities may be more time-consuming, complex, or costly than expected; the possibility that anticipated synergies, efficiencies, and other benefits of the Merger may not be realized, or may be realized more slowly than anticipated; and risks associated with managing a larger, more complex combined organization and effectively integrating systems, processes, operations, and cultures; adverse economic conditions, 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; international, national or local economic conditions that could adversely affect us or our clients; reductions in client spending, a slowdown in client payments or a deterioration or disruption in the credit markets; the ability to attract new clients and retain existing clients in the manner anticipated; changes in client marketing and communications services requirements; failure to manage potential conflicts of interest between or among clients; unanticipated changes related to competitive factors in the marketing and communications services industries; unanticipated changes to, or an inability to hire and retain, key personnel; currency exchange rate fluctuations; reliance on information technology systems and risks related to cybersecurity incidents; effective management of the risks, challenges and efficiencies presented by utilizing artificial intelligence, or AI, technologies and related partnerships in our business, and their use by our competitors; failure to adapt to technological developments; our liquidity, long-term financing needs, credit ratings and access to capital markets; changes in legislation or governmental regulations affecting us or our clients; losses on media purchases and production costs incurred on behalf of clients; risks associated with assumptions we make in connection with our acquisitions, critical accounting estimates and legal proceedings; Our international operations, which are subject to the risks of currency repatriation restrictions, social or political conditions and an evolving regulatory environment in high-growth markets and developing countries; risks related to our 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; changes in tax rates, tax laws, regulations or interpretations, or adverse outcomes of tax audits or proceedings; and other business, financial, operational and legal risks and uncertainties detailed from time to time in our filings with the Securities and Exchange Commission ("SEC"). The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that may affect our 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-Kand in other documents filed from time to time with the SEC. Except as required under applicable law, we do not assume any obligation to update these forward-looking statements. 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. EBITA is defined as earnings before interest, income taxes, and amortization, principally from 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 diluted share – Omnicom Group Inc. as additional operating performance measures. Free Cash Flow is defined as net income plus depreciation, amortization, share based compensation expense plus/(less) other items to reconcile to net cash (used in) provided by operating activities. We believe Free Cash Flow is a useful measure of liquidity to evaluate our ability to generate excess cash from our operations. Primary Uses of Cash is defined as dividends to common shareholders, dividends paid to non-controlling interest shareholders, capital expenditures, cash paid on acquisitions, payments for additional interest in controlled subsidiaries and stock repurchases, net of the proceeds from our stock plans, and excludes changes in operating capital and other investing and financing activities, including commercial paper issuances and redemptions used to fund working capital changes. We believe this liquidity measure is useful in identifying the significant uses of our cash. Net Free Cash Flow is defined as Free Cash Flow less the Primary Uses of Cash. Net Free Cash Flow is one of the metrics used by us to assess our sources and uses of cash and was derived from our consolidated statements of cash flows. We believe that this liquidity measure is meaningful for understanding our primary sources and primary uses of that cash flow. EBITDA is defined as earnings before interest, taxes, depreciation and amortization of intangible assets. Net Debt is defined as total debt less cash, cash equivalents and short-term investments. We believe net debt, together with the comparable GAAP measures, reflects one of the liquidity metrics used by us to assess our cash management. 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.
