Omnicom Group Reports Third Quarter and Year-to-Date

2020 Results

NEW YORK, October 27, 2020 - Omnicom Group Inc. (NYSE: OMC) today announced net income - Omnicom Group Inc. for the third quarter of 2020 of $313.3 million compared to net income - Omnicom Group Inc. of $290.2 million in the third quarter of 2019. Diluted net income per share for the third quarter of 2020 was $1.45 per share compared to diluted net income per share of $1.32 for the third quarter of 2019.

Net income - Omnicom Group Inc. and diluted net income per share - Omnicom Group Inc. in the third quarter of 2020 included a net after-tax increase of $52.3 million and $0.24 per share, respectively, related to reimbursements and tax credits under government programs in several countries where we have operations, as discussed further below.

Primarily due to the negative effects on our revenue arising from the coronavirus disease 2019 ("COVID-19") pandemic, Omnicom’s worldwide revenue in the third quarter of 2020 decreased 11.5% to $3,206.5 million from $3,623.8 million in the third quarter of 2019. The components of the change in revenue included an increase in revenue from the positive impact of foreign currency translation of 0.5%, a decrease in acquisition revenue, net of disposition revenue of 0.3% and a decrease in revenue from negative organic growth of 11.7% when compared to the third quarter of 2019.

Organic growth in the third quarter of 2020 as compared to the third quarter of 2019 in our five fundamental disciplines was as follows: Advertising decreased 11.7%, CRM Consumer Experience decreased 19.3%, CRM Execution & Support decreased 19.4%, Public Relations decreased 3.4% and Healthcare increased 3.8%.

Across our regional markets, organic growth in the third quarter of 2020 as compared to the third quarter of 2019 was as follows: the United States decreased 11.4%, Other North America decreased 7.6%, the United Kingdom decreased 12.5%, the Euro Markets & Other Europe decreased 9.6%, Asia Pacific decreased 12.8%, Latin America decreased 22.3% and the Middle East & Africa decreased 21.4%.

 

Omnicom Group Inc.

Operating profit increased $28.1 million, or 5.9%, to $501.4 million compared to $473.3 million during the third quarter of 2019. Our operating margin for the third quarter of 2020 increased to 15.6% versus 13.1% for the third quarter of 2019.

Salary and related service costs for the third quarter of 2020 includes the reduction in operating expenses related to reimbursements and tax credits under government programs in several countries where we have operations, including the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") in the U.S., the Kurzarbeit program in Germany, and other programs in the U.K., France, Canada and other jurisdictions. The impact of these items reduced salary and related service costs and increased operating profit by $68.7 million in the third quarter of 2020.

For the third quarter of 2020, our effective income tax rate increased period-over-period to 26.7% from 26.5%.

Year-to-Date

Net income - Omnicom Group Inc. for the nine months ended September 30, 2020 decreased $376.8 million to $547.3 million compared to $924.1 million in the same period in 2019. Diluted net income per share - Omnicom Group Inc. for the nine months ended September 30, 2020 decreased $1.64 to $2.53 per share compared to $4.17 per share for the nine months ended September 30, 2019.

Net income - Omnicom Group Inc. and diluted net income per share - Omnicom Group Inc. for the nine months ended September 30, 2020 included a net after-tax decrease of $133.9 million and $0.62 per share, respectively, as a result of repositioning costs and a net loss on dispositions during the second quarter of 2020 as well as the credit related to reimbursements and tax credits under government programs in several countries where we have operations, as discussed further below.

Primarily due to the negative effects on our revenue arising from the COVID-19 pandemic in the second and third quarters of 2020, worldwide revenue for the nine months ended September 30, 2020 decreased 12.9% to $9,414.1 million from $10,812.5 million in the same period of 2019. The components of the change in revenue included a decrease in revenue from the negative impact of foreign currency translation of 0.9%, a decrease in acquisition revenue, net of disposition revenue of 0.4% and a decrease in revenue from negative organic growth of 11.7% when compared to the same period of 2019.

Omnicom Group Inc.

Organic growth for the nine months ended September 30, 2020 compared to the same period in 2019 in our five fundamental disciplines was as follows: Advertising decreased 13.2%, CRM Consumer Experience decreased 15.8%, CRM Execution & Support decreased 15.6%, Public Relations decreased 5.8% and Healthcare increased 5.3%.

Across our regional markets, organic growth for the nine months ended September 30, 2020 as compared to the same period of 2019 was as follows: the United States decreased 10.3%, Other North America decreased 12.7%, the United Kingdom decreased 11.1%, the Euro Markets & Other Europe decreased 14.4%, Asia Pacific decreased 10.2%, Latin America decreased 17.5% and the Middle East & Africa decreased 29.7%.

Operating profit decreased $491.8 million, or 33.3%, to $984.1 million from $1,475.9 million for the nine months ended September 30, 2019. Our operating margin for the nine months ended September 30, 2020 decreased to 10.5% versus 13.6% for the same period of 2019.

Operating profit for the nine months ended September 30, 2020 includes a net decrease aggregating $160.1 million due to repositioning costs recorded during the second quarter of 2020, comprised of incremental severance charges, right-of-use asset impairments and other real estate costs of $252.8 million, and a net loss on the disposition of certain subsidiaries and other charges of $25.1 million, partially offset by reimbursements and tax credits under government programs in several countries where we have operations, including the CARES Act in the U.S., the Kurzarbeit program in Germany, and other programs in the U.K., France, Canada and other jurisdictions, which reduced salary and related service costs by $117.8 million.

Our effective tax rate for the nine months ended September 30, 2020 increased period-over-period to 28.5% from 26.0%. The non-deductibility in certain jurisdictions of a portion of the repositioning costs and net loss on dispositions recorded in the second quarter of 2020 had the effect of increasing our effective tax rate for the nine months ended September 30, 2020 from 26.6% to 28.5%. In addition, in the same period of 2019, income tax expense was reduced by $10.8 million, primarily from the net favorable settlements of uncertain tax positions in certain jurisdictions. As a result, our effective rate for the nine months ended September 30, 2020 would have approximated the rate in the same period in 2019 after considering these items.

COVID-19 Business Update

The COVID-19 pandemic has significantly impacted the global economy, our business and the results of operations. Public health efforts to mitigate the impact of the pandemic include government actions such as travel restrictions, limitations on public gatherings, shelter in place orders and mandatory closures. These actions have negatively impacted many of our clients' businesses and in turn clients have reduced or plan to reduce their demand for our services. As a result, we experienced a reduction in our revenue beginning late in the first quarter of 2020, as compared to the same period in 2019. The reduction in our revenue continued during the second and third quarters of 2020 and is expected to continue for the remainder of the year. Such reductions in revenue could adversely impact our ongoing results of operations and financial position and the effects could be material.

While we expect the pandemic to affect substantially all of our clients, certain industry sectors have been affected more immediately and more significantly than others, including travel, lodging and entertainment, energy and oil and gas, non-essential retail and automotive. Clients in these industries have already acted to cut costs, including postponing or reducing marketing communication expenditures. While certain industries such as healthcare and pharmaceuticals, technology and telecommunications, financial services and consumer products have fared relatively well to date, conditions are volatile and economic uncertainty cuts across all clients, industries and geographies. Overall, while we have a diversified portfolio of service offerings, clients and geographies, demand for our services can be expected to decline as marketers reduce expenditures in the short term due to the uncertain impact of the pandemic on the global economy. During the second quarter of 2020, we realigned our agencies' cost structures, which included severance actions and furloughs to reduce the workforce, right-of-use asset impairments and other real estate costs, a net loss on the disposition of certain subsidiaries and other charges. These actions were taken to tailor their services and capabilities to changes in client demand.

As we previously reported, during the first half of 2020, we took numerous proactive steps to strengthen our liquidity and financial position that we expect will help mitigate the potential impacts of COVID-19, including:

• The amendment and extension of our $2.5 billion credit facility to February 2025,

• The suspension of our share repurchase program,

Page 4

Omnicom Group Inc.

• The issuance in February of $600 million 10-year 2.45% Senior Notes, which were used to finance the early redemption of the remaining $600 million of 4.45% Senior Notes that were due in August 2020,

• The issuance in early April of an additional $600 million 10-year 4.20% Senior Notes, and

• The completion in early April, of a $400 million 364-day revolving credit facility, which is in addition to our existing $2.5 billion revolving credit facility that expires in February 2025.

We have no long-term debt maturing until May 2022.

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.

The foreign exchange rate impact is the difference between the current period revenue in U.S. Dollars and the current period constant cur ren cy revenue. (b) Acquisition revenue, net of disposition revenue: Acquisition revenue is calculated as if the acquisition occurred twelve mont hs 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 dispos iti on revenue amounts are netted in the presentation above. (c) Organic growth: calculated by subtracting the foreign exchange rate impact, and the acquisition revenue, net of disposition r eve nue components from total revenue growth. 4 October 27, 2020

Forward - Looking Statements Certain statements in this presentation constitute forward - looking statements, including statements within the meaning of the Pr ivate Securities Litigation Reform Act of 1995. In addition, from time to time, Omnicom Group Inc. ("Omnicom" or the "Company") or its representatives have made, or may make, forward - looking statements, orally or in writin g. 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 the Company’s managem ent 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,” “sho uld,” “would,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or similar words, phrases or expressions. These forward - looking statements are sub ject 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: international, national or local economic conditions that could adversely affect the Company or its clients, including those caused by the outbreak of coronavirus dise ase 2019 (“COVID - 19”); losses on media purchases and production costs incurred on behalf of clients; reductions in client spending, a slowdown in client payments and a deterioration 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 le gis lation or governmental regulations affecting the Company or its clients; risks associated with assumptions the Company makes in connection with its cri tical 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 lis t o f 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 Ite m 1A, “Risk Factors” in Omnicom’s most recent Annual Report on Form 10 - K and other documents filed from time to time with the Securities and Exchange Commission. 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. 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 23 to 25. 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 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 cont rolled subsidiaries and stock repurchases, net of the proceeds from our stock plans, and excludes changes in operating capital and o the r 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 excludes the non - cash amortization expense of intangible assets (primarily consisting of amortizatio n arising from acquisitions). Accordingly, we believe it is a useful measure 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 th e 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. Other Information All dollar amounts are in millions except for per share figures on page s 1 and 2 a nd the net cash returned to shareholders figures on page 21.
