14Notes (a) For the twelve months ended December 31, 2024, operating expenses included $57.8 million ($42.9 million after-tax) of repositioning costs, primarily related to severance, recorded in the second quarter of 2024. Included in selling, general and administrative expenses in the fourth quarter of 2024 are acquisition transaction costs of $14.6 million ($13.1 million after-tax), related to the proposed merger with IPG. The net impact of these items reduced operating income for 2024 by $72.4 million ($56.0 million after-tax) and reduced diluted net income per share - Omnicom Group Inc. by $0.28. For the twelve months ended December 31, 2023, operating expenses included real estate operating lease impairment charges, severance and other exit costs of $191.5 million ($145.5 million after-tax) related to repositioning actions we took in the first and second quarters of 2023 to reduce our real estate requirements, rebalance our workforce, and consolidate operations in certain markets. In addition, in the second quarter of 2023, we recorded a gain of $78.8 million ($55.9 million after-tax) on the disposition of certain of our research businesses in the Execution & Support discipline. Included in the fourth quarter of 2023 within selling, general and administrative expenses are acquisition transaction costs of $14.5 million ($13.0 million after-tax), primarily related to the purchase of Flywheel Digital in January 2024. The net impact of these items reduced operating income for 2023 by $127.2 million ($102.6 million after-tax) and reduced diluted net income per share - Omnicom Group Inc. by $0.50. (b) Income tax for the twelve months ended December 31, 2024 and 2023 included impacts related to real estate and other repositioning actions and gain on disposition of subsidiary in 2023. (c) Third-party service costs include third-party supplier costs when we act as principal in providing services to our clients. (d) Third-party incidental costs primarily consist of client-related travel and incidental out-of-pocket costs, which we bill back to the client directly at our cost and which we are required to include in revenue. (e) Constant Dollar ("C$") expense is calculated by translating the current period’s local currency expense using the prior period average exchange rates to derive current period C$ expense. The foreign exchange rate impact is the difference between the current period expense in U.S. Dollars and the current period C$ expense. Financial Notes Definitions (1) 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. (2) 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 presentation on page 4. (3) Organic growth: calculated by subtracting the foreign exchange rate impact, and the acquisition revenue, net of disposition revenue components from total revenue growth. (4) See page 18 for the reconciliation of non-GAAP financial measures, which reconciles Free Cash Flow to the Net Cash Provided by Operating Activities and Net Free Cash Flow to the Net Increase (Decrease) in Cash and Cash Equivalents for the periods presented on page 10. The Free Cash Flow, Primary Uses of Cash and Net Free Cash Flow amounts presented on page 10 are non-GAAP liquidity measures. See page 22 for the definition of Net Free Cash Flow. (5) EBITA, EBITDA, and Non-GAAP Adjusted Net Income per share - Diluted are non-GAAP performance measures. Beginning with the first quarter of 2024, we define EBITA as earnings before interest, taxes, and amortization of acquired intangible assets and internally developed strategic platform assets. As a result, we reclassified the prior year periods to be consistent with the revised definition, which reduced EBITA from previously reported amounts. Non-GAAP Adjusted Net Income per share - Diluted reflects the after-tax effects of amortization of acquired intangible assets and internally developed strategic platform assets. 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 and allows for comparability of the periods presented. See page 22 for the definition of these measures and pages 19 and 21 for the reconciliation of Non-GAAP financial measures. (6) Net Debt is a non-GAAP liquidity measure. See page 22 for the definition of this measure, which is reconciled in the table on page 11. (7) Return on Invested Capital is After Tax Reported Operating Income (a non-GAAP performance measure – see page 22 for the definition of this measure and page 18 for the reconciliation of non-GAAP financial measures) divided by the average of Invested Capital at the beginning and the end of the period (book value of all long-term liabilities, including those related to operating leases, short-term interest bearing debt, the short-term liability related to operating leases plus shareholders’ equity less cash, cash equivalents, short-term investments, and operating lease right of use assets). (8) Return on Equity is Reported Net Income for the given period divided by the average of shareholders’ equity at the beginning and end of the period. (9) The Free Cash Flow amounts presented on page 16 are non-GAAP liquidity measures. See page 22 for the definition of this measure and page 18 for the reconciliation of the non-GAAP financial measures, which reconciles Free Cash Flow to the Net Cash Provided by Operating Activities for the periods presented on page 16.

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 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 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.
