Third Quarter 2022 Results

Revenues

Worldwide revenue growth in the third quarter of 2022 compared to the third quarter of 2021 was led by an increase in revenue from organic growth of $257.7 million, or 7.5%. Acquisition revenue, net of disposition revenue, was a decrease of $32.7 million, or 1.0%, primarily reflecting the disposition of our businesses in Russia in the first quarter of 2022. The impact of foreign currency translation was a decrease of $216.6 million, or 6.3%. Reported total revenue in the third quarter of 2022 increased $8.4 million, or 0.2%.

Organic growth in the third quarter of 2022 compared to the third quarter of 2021 increased across all of our fundamental disciplines, including: 5.9% for Advertising & Media, 16.3% for Precision Marketing, 12.6% for

280 Park Avenue, New York, NY 10017. Tel (212) 415-3672

Public Relations, 11.1% for Commerce & Brand Consulting, 5.0% for Healthcare, 3.9% for Execution & Support, and 2.3% for Experiential.

Organic growth in the third quarter of 2022 compared to the third quarter of 2021 increased across our geographic markets as follows: 7.6% for the United States, 11.5% for the United Kingdom, 6.0% for the Euro Markets & Other Europe, 4.4% for Asia Pacific, 13.1% for Latin America, 7.7% for Other North America, and 12.2% for the Middle East & Africa.

Expenses

Operating expenses increased $4.0 million, or 0.1%, to $2,897.4 million compared to the third quarter of 2021.

Salary and service costs, which tend to fluctuate with changes in revenue, are comprised of salary and related costs, and third-party service costs. In total, salary and service costs increased $14.3 million, or 0.6%. Salary and related costs increased $18.8 million, or 1.1%, due primarily to the increase in organic revenue, an increase in headcount, and an increase in client-related business activities. Third-party service costs decreased $4.5 million, or 0.6%, due primarily to the disposition of our businesses in Russia in the first quarter of 2022, partially offset by an increase in organic revenue.

Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, decreased $4.5 million, or 1.6%, to $281.0 million, due to lower rent and other occupancy costs, partially offset by an increase in general office expenses resulting from the return of our workforce to the office.

SG&A expenses decreased $8.6 million, or 9.1%, to $86.4 million.

Operating Profit

Operating profit increased $4.4 million, or 0.8%, to $546.0 million compared to the third quarter of 2021. The related operating profit margin was 15.9% compared to 15.8% for the third quarter of 2021.

Interest Expense, net

Net interest expense in the third quarter of 2022 decreased $14.6 million to $29.1 million compared to the third quarter of 2021. Interest expense increased $1.3 million to $52.0 million, and interest income increased $15.9 million to $22.9 million, primarily as a result of higher interest rates on cash balances and short-term investments.

Income Taxes

Our effective tax rate of 26.1% in the third quarter of 2022 increased from 24.1% in the third quarter of 2021 primarily related to the favorable settlements of uncertain tax positions in certain jurisdictions in the prior year period.

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

Net income - Omnicom Group Inc. for the third quarter of 2022 increased $8.9 million, or 2.5%, to $364.5 million compared to the third quarter of 2021. Diluted shares outstanding decreased to 206.3 million, or 4.7%, from 215.4 million. Diluted net income per share of $1.77 increased $0.12, or 7.3%, from $1.65 per share.

EBITA

EBITA in the third quarter of 2022 increased $5.8 million, or 1.0%, to $566.1 million compared to the third quarter of 2021. The related EBITA margin increased to 16.4% from 16.3%.

Risks and Uncertainties

Global economic challenges, including the impact of the war in Ukraine, the COVID-19 pandemic, rising inflation, rising interest rates and supply-chain disruptions 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 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, 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 the disposition 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 use certain non-GAAP financial measures in describing our performance. We use EBITA (defined as earnings before interest, taxes and amortization of intangible assets) and EBITA Margin (defined as EBITA divided by revenue) as additional operating performance measures, which exclude the non-cash amortization expense of intangible assets (primarily consisting of amortization of intangible assets arising from acquisitions). We believe EBITA and EBITA Margin are useful measures for investors to evaluate the performance of our business. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Non-GAAP financial measures reported by us may not be comparable to similarly titled amounts reported by other companies.

Forward-Looking Statements
Certain statements in this press release constitute forward-looking statements, including statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, from time to time, the Company or its 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 position, or otherwise, based on current beliefs of the Company’s management as well as assumptions made by, and information currently available to, the Company’s management.

These forward-looking statements are subject to various risks and uncertainties, many of which are outside the Company’s 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: adverse economic conditions, including those caused by the the war in Ukraine; the impact of the COVID-19 pandemic; severe and sustained inflation in countries that comprise our major markets; rising interest rates; supply chain issues affecting the distribution of our clients’ products; international, national or local economic conditions that could adversely affect the Company or its clients; losses on media purchases and production costs incurred on behalf of clients; reductions in client spending, a slowdown in client payments and a deterioration or a disruption in the credit markets; the ability to attract new clients and retain existing clients in the manner anticipated; changes in client advertising, marketing and corporate communications requirements; failure to manage potential conflicts of interest between or among clients; unanticipated changes relating to competitive factors in the advertising, marketing and corporate communications industries; the ability to hire and retain key personnel; currency exchange rate fluctuations; reliance on information technology systems; changes in legislation or governmental regulations affecting the Company or its clients; risks associated with assumptions the Company makes in connection with its critical accounting estimates and legal proceedings; and the Company’s international operations, which are subject to the risks of currency repatriation restrictions, social or political conditions and regulatory environment. 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 for the year ended December 31, 2021.

16 Operating Expense Detail - Constant $ (a) Third-party service costs are expenses paid to third-party vendors incurred primarily in connection with performance obligations for our services where we have determined that we are acting as principal. These third-party expenses also include incidental costs incurred in the performance of our services including airfare, mileage, hotel and other out-of-pocket expenses. (b) In the first quarter of 2022, we recorded a pre-tax charge of $113.4 million in connection with charges arising from the effects of the war in Ukraine. (c) Constant Dollar ("C$") 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.

Forward-Looking Statements Certain statements in this presentation constitute forward-looking statements, including statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, from time to time, the Company or its 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 position, or otherwise, based on current beliefs of the Company’s management as well as assumptions made by, and information currently available to, the Company’s 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 the Company’s 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: adverse economic conditions, including those caused by the the war in Ukraine; the impact of the COVID-19 pandemic; severe and sustained inflation in countries that comprise our major markets; rising interest rates; supply chain issues affecting the distribution of our clients’ products; international, national or local economic conditions that could adversely affect the Company or its clients; losses on media purchases and production costs incurred on behalf of clients; reductions in client spending, a slowdown in client payments and a deterioration or a disruption in the credit markets; the ability to attract new clients and retain existing clients in the manner anticipated; changes in client advertising, marketing and corporate communications requirements; failure to manage potential conflicts of interest between or among clients; unanticipated changes relating to competitive factors in the advertising, marketing and corporate communications industries; the ability to hire and retain key personnel; currency exchange rate fluctuations; reliance on information technology systems; changes in legislation or governmental regulations affecting the Company or its clients; risks associated with assumptions the Company makes in connection with its critical accounting estimates and legal proceedings; and the Company’s international operations, which are subject to the risks of currency repatriation restrictions, social or political conditions and regulatory environment. 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 for the year ended December 31, 2021. Except as required under applicable law, the Company does 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 use Adjusted Operating Profit, Adjusted Operating Profit Margin, Adjusted EBITA, Adjusted EBITA Margin, Adjusted Net Interest Expense, Adjusted Income Tax Expense, Adjusted Adjusted Net Income – Omnicom Group Inc. and Adjusted Net Income per diluted share – Omnicom Group Inc. as additional operating performance measures. We believe these measures are useful in evaluating the impact of certain items on operating performance and allows for comparability between reporting periods. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP. Non-GAAP financial measures as reported by us may not be comparable to similarly titled amounts reported by other companies. We provide a reconciliation of non-GAAP measures to the comparable GAAP measures on pages 17 through 20. The Non-GAAP measures used in this presentation include the following: Free Cash Flow, 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, 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, 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, defined as operating profit before interest, taxes, depreciation and amortization of intangible assets. We believe EBITDA is a meaningful operating performance measure because the financial covenants in our credit facilities are based on EBITDA. EBITA, defined as operating profit before interest, taxes and amortization of intangible assets and EBITA margin, 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 intangible assets (primarily consisting of amortization arising from acquisitions). Accordingly, we believe they are useful measures for investors to evaluate the performance of our business. Net Debt, 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. After Tax Reported Operating Profit, defined as reported operating profit less income taxes calculated using the effective tax rate for the applicable period. Management uses after tax operating profit as a measure of after tax operating performance as it excludes the after tax effects of financing and investing activities on results of operations.
