Sarah Glickman, Chief Financial Officer, said, "We are raising our financial guidance for the full year 2021 in light of our third quarter outperformance and continued business momentum carrying into the fourth quarter.

Revenue, Revenue ex-TAC and Gross Profit

Revenue increased by 8% year-over-year in Q3 2021, or 8% at constant currency, to $509 million (Q3 2020: $470 million). Revenue ex-TAC in the third quarter increased 13% year-over-year, or 14% at constant currency, to $211 million (Q3 2020: $186 million). Revenue ex-TAC as a percentage of revenue, or Revenue ex-TAC margin, was 41% (Q3 2020: 40%), up 200 basis points year-over-year, largely driven by Retail Media and the acceleration of our client transition to the Retail Media Platform.

•Marketing Solutions revenue grew 11% (or 12% at constant currency) and Marketing Solutions revenue ex-TAC grew 8% (or 8% at constant currency), driven by healthy demand from Retail clients, both on our retargeting and audience targeting solutions, partially offset by anticipated identity and privacy changes.

•Retail Media revenue decreased 14% (or 15% at constant currency) reflecting the impact related to the ongoing client migration to our Retail Media Platform ("RMP"). Retail Media revenue ex-TAC increased 65% (or 65% on a constant currency basis), driven by continued strength in Retail Media onsite, new client integrations and growing network effects of the RMP.

•In the Americas, Revenue was flat year-over-year, or flat at constant currency, to $204 million and represented 40% of total Revenue. Revenue ex-TAC increased 19% year-over-year, or 18% at constant currency, to $88 million and represented 42% of total Revenue ex-TAC.

•In Asia-Pacific, Revenue increased 18% year-over-year, or 21% at constant currency, to $116 million and represented 23% of total Revenue. Revenue ex-TAC increased 13% year-over-year, or 15% at constant currency, to $47 million and represented 22% of total Revenue ex-TAC.

Gross profit increased by 16% year-over-year in Q3 2021, or 16% at constant currency, to $176 million (Q3 2020: $151 million).

Net Income and Adjusted Net Income

Net income grew 358% to $24 million in Q3 2021 (Q3 2020: $5 million). Net income margin as a percentage of revenue was 5% (Q3 2020: 1%).

Adjusted EBITDA and Operating Expenses

Adjusted EBITDA increased 38% year-over-year, or 37% at constant currency, to $68 million (Q3 2020: $49 million), driven by the Revenue ex-TAC performance over the period and effective cost management balanced with growth investments.

Business Outlook

The following forward-looking statements reflect Criteo’s expectations as of November 3, 2021.

Fiscal year 2021 guidance:

•We raise our Revenue ex-TAC growth outlook to approximately +10% at constant-currency.

•We raise our Adjusted EBITDA margin outlook to approximately 35% of Revenue ex-TAC.

Fourth quarter 2021 guidance:

•We expect Revenue ex-TAC between $271 million and $274 million, or year-over-year growth at constant-currency of +8% to +9%.

•We expect Adjusted EBITDA between $107 million and $110 million, or an Adjusted EBITDA margin of 39% to 40%.

The above guidance for the fourth quarter and fiscal year ending December 31, 2021 assumes the following exchange rates for the main currencies impacting our business: a U.S. dollar-euro rate of 0.839, a U.S. dollar-Japanese Yen rate of 109, a U.S. dollar-British pound rate of 0.717, a U.S. dollar-Korean Won rate of 1,144 and a U.S. dollar-Brazilian real rate of 5.34.

The above guidance assumes no acquisitions are completed during the fourth quarter and fiscal year ended December 31, 2021.

Reconciliation of Revenue ex-TAC and Adjusted EBITDA guidance to the closest corresponding U.S. GAAP measures is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures; in particular, the measures and effects of equity awards compensation expense specific to equity compensation awards that are directly impacted by unpredictable fluctuations in our share price. The variability of the above charges could potentially have a significant impact on our future U.S. GAAP financial results

Extension of Share Repurchase Authorization from $100 million to $175 million

Criteo continues to execute on its strategic plan and Company transformation, investing in the growth of the business and leveraging its strong balance sheet position.

Criteo today announces that the board of directors has authorized the extension of its current share repurchase program of up to $100 million of the Company’s outstanding American Depositary Shares to an increased amount of up to $175 million. The Company intends to use repurchased shares under this extended program to satisfy employee equity obligations in lieu of issuing new shares, which would limit future dilution for its shareholders, as well as to fund potential acquisitions in the future.

Under the terms of the authorization, the stock purchases may be made from time to time on the NASDAQ Global Select Market in compliance with applicable state and federal securities laws and applicable provisions of French corporate law. The timing and amounts of any purchases will be based on market conditions and other factors including price, regulatory requirements and capital availability, as determined by Criteo’s management team. The program does not require the purchase of any minimum number of shares and may be suspended, modified or discontinued at any time without prior notice.

Non-GAAP Financial Measures

This press release and its attachments include the following financial measures defined as non-GAAP financial measures by the U.S. Securities and Exchange Commission ("SEC"): Revenue ex-TAC, Revenue ex-TAC by Region, Revenue ex-TAC by Solution, Revenue ex-TAC margin, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted diluted EPS, Free Cash Flow and Non-GAAP Operating Expenses. These measures are not calculated in accordance with U.S. GAAP.

Revenue ex-TAC is our revenue excluding Traffic Acquisition Costs ("TAC") generated over the applicable measurement period and Revenue ex-TAC by Region reflects our Revenue ex-TAC by our geographies. Revenue ex-TAC, Revenue ex-TAC by Region, Revenue ex-TAC by Solution, and Revenue ex-TAC margin are key measures used by our management and board of directors to evaluate our operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of TAC from revenue can provide a useful measure for period-to-period comparisons of our business and across our geographies.

Accordingly, we believe that Revenue ex-TAC, Revenue ex-TAC by Region, Revenue ex-TAC by Solution and Revenue ex-TAC margin provide useful information to investors and the market generally in understanding and evaluating our operating results in the same manner as our management and board of directors.

Adjusted EBITDA is our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs and restructuring related and transformation costs.

Adjusted EBITDA and Adjusted EBITDA margin are key measures used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. In particular, we believe that by eliminating equity awards compensation expense, pension service costs and restructuring related and transformation costs, Adjusted EBITDA and Adjusted EBITDA margin can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors and the market generally in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Adjusted Net Income is our net income adjusted to eliminate the impact of equity awards compensation expense, amortization of acquisition-related intangible assets, restructuring related and transformation costs and the tax impact of these adjustments. Adjusted Net Income and Adjusted diluted EPS are key measures used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital.

In particular, we believe that by eliminating equity awards compensation expense, amortization of acquisition-related intangible assets, restructuring related and transformation costs and the tax impact of these adjustments, Adjusted Net Income and Adjusted diluted EPS can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted Net Income and Adjusted diluted EPS provide useful information to investors and the market generally in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Free Cash Flow is defined as cash flow from operating activities less acquisition of intangible assets, property, plant and equipment and change in accounts payable related to intangible assets, property, plant and equipment. Free Cash Flow Conversion is defined as free cash flow divided by Adjusted EBITDA. Free Cash Flow and Free Cash Flow Conversion are key measures used by our management and board of directors to evaluate the Company's ability to generate cash. Accordingly, we believe that Free Cash Flow and Free Cash Flow Conversion permit a more complete and comprehensive analysis of our available cash flows.

Non-GAAP Operating Expenses are our consolidated operating expenses adjusted to eliminate the impact of depreciation and amortization, equity awards compensation expense, pension service costs, and restructuring related and transformation costs. The Company uses Non-GAAP Operating Expenses to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short-term and long-term operational plans, and to assess and measure our financial performance and the ability of our operations to generate cash. We believe Non-GAAP Operating Expenses reflects our ongoing operating expenses in a manner that allows for meaningful period-to-period comparisons and analysis of trends in our business. As a result, we believe that Non-GAAP Operating Expenses provides useful information to investors in understanding and evaluating our core operating performance and trends in the same manner as our management and in comparing financial results across periods. In addition, Non-GAAP Operating Expenses is a key component in calculating Adjusted EBITDA, which is one of the key measures the Company uses to provide its quarterly and annual business outlook to the investment community.

Please refer to the supplemental financial tables provided in the appendix of this press release for a reconciliation of Revenue ex-TAC to revenue, Revenue ex-TAC by Region to revenue by region, Revenue ex-TAC by Solution to revenue by solution, Adjusted EBITDA to net income, Adjusted Net Income to net income, Free Cash Flow to cash flow from operating activities, and Non-GAAP Operating Expenses to operating expenses, in each case, the most comparable U.S. GAAP measure. Our use of non-GAAP financial measures has limitations as an analytical tool, and you should not consider such non-GAAP measures in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: 1) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; and 2) other companies may report Revenue ex-TAC, Revenue ex-TAC by Region, Revenue ex-TAC by Solution, Adjusted EBITDA, Adjusted Net Income, Free Cash Flow, Non-GAAP Operating Expenses or similarly titled measures but calculate them differently or over different regions, which reduces their usefulness as comparative measures. Because of these and other limitations, you should consider these measures alongside our U.S. GAAP financial results, including revenue and net income.

(1) We define Revenue ex-TAC as our revenue excluding traffic acquisition costs generated over the applicable measurement period. Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution are not measures calculated in accordance with U.S. GAAP. We have included Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution because they are key measures used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of TAC from revenue and review of these measures by region and solution can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region, and Revenue ex-TAC by Solution provide useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution has limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; (b) other companies may report Revenue, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution, or similarly titled measures but define the regions, and product families differently, which reduces their effectiveness as a comparative measure; and (c) other companies may report Revenue ex-TAC or similarly titled measures but calculate them differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Revenue ex-TAC and Revenue, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution alongside our other U.S. GAAP financial results, including revenue. The above tables provide a reconciliation of Revenue ex-TAC to revenue, Revenue ex-TAC by Region to revenue by region and Revenue ex-TAC by Solution to revenue by solution.

(2) Criteo operates as one operating segment. From January 1, 2021 we have disaggregated revenues between Marketing Solutions and Retail Media. A strategic building block of Criteo’s Commerce Media Platform, the Retail Media Platform, introduced in June 2020, is a self-service solution providing transparency, measurement and control to brands and retailers. In all arrangements running on this platform, Criteo recognizes revenue on a net basis, whereas revenue from arrangements running on legacy Retail Media solutions are accounted for on a gross basis. We expect most clients using Criteo’s legacy Retail Media solutions to transition to this platform by the second half of 2022. As new clients onboard and existing clients transition to the Retail Media Platform, Revenue may decline but Revenue ex-TAC margin will increase. Revenue ex-TAC will not be impacted by this transition.

(1) For the Nine Months Ended September 30, 2020, the Company recognized an accelerated amortization expense for Manage technology due to a revised useful life in 2019 ($4.0 million in Research and development).

(2) For the Three Months and the Nine Months Ended September 2021, and September 2020, respectively, the Company recognized restructuring related and transformation costs following its new organizational structure implemented to support its Commerce Media Platform strategy:

	Three Months Ended				Nine Months Ended

For the three months ended and the nine months ended September 30, 2021 and September 30, 2020, respectively, the cash outflows related to restructuring related and transformation costs were $4.4 million and $ 6.2 million, and $20.9 million and $13.0 million respectively, and were mainly comprised of payroll costs, broker and termination penalties related to real-estate facilities and other consulting fees.

(3) We define Adjusted EBITDA as our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs, acquisition-related costs and restructuring related and transformation costs. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. We have included Adjusted EBITDA because it is a key measure used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short-term and long-term operational plans. In particular, we believe that the elimination of equity awards compensation expense, pension service costs, and restructuring related and transformation costs in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; (b) Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (c) Adjusted EBITDA does not reflect the potentially dilutive impact of equity-based compensation; (d) Adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us; and (e) other companies, including companies in our industry, may calculate Adjusted EBITDA or similarly titled measures differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Adjusted EBITDA alongside our U.S. GAAP financial results, including net income.

The Company uses Non-GAAP Operating Expenses to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short-term and long-term operational plans, and to assess and measure our financial performance and the ability of our operations to generate cash. We believe Non-GAAP Operating Expenses reflects our ongoing operating expenses in a manner that allows for meaningful period-to-period comparisons and analysis of trends in our business. As a result, we believe that Non-GAAP Operating Expenses provides useful information to investors in understanding and evaluating our core operating performance and trends in the same manner as our management and in comparing financial results across periods. In addition, Non-GAAP Operating Expenses is a key component in calculating Adjusted EBITDA, which is one of the key measures we use to provide our quarterly and annual business outlook to the investment community.

(1) For the Nine Months Ended September 30, 2020, the Company recognized an accelerated amortization expense for Manage technology due to a revised useful life in 2019 ($4.0 million in Research and development).

(2) We define Adjusted Net Income as our net income adjusted to eliminate the impact of equity awards compensation expense, amortization of acquisition-related intangible assets, acquisition-related costs, restructuring related and transformation costs, and the tax impact of the foregoing adjustments. Adjusted Net Income is not a measure calculated in accordance with U.S. GAAP. We have included Adjusted Net Income because it is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of equity awards compensation expense, amortization of acquisition-related intangible assets, restructuring related and transformation costs and the tax impact of the foregoing adjustments in calculating Adjusted Net Income can provide a useful measure for period-to-period comparisons of our business. Accordingly, we believe that Adjusted Net Income provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Adjusted Net Income has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) Adjusted Net Income does not reflect the potentially dilutive impact of equity-based compensation or the impact of certain acquisition-related costs; and (b) other companies, including companies in our industry, may calculate Adjusted Net Income or similarly titled measures differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Adjusted Net Income alongside our other U.S. GAAP-based financial results, including net income.

Management reviews and analyzes business results excluding the effect of foreign currency translation because they believe this better represents our underlying business trends. The table above reconciles the actual results presented in this section with the results presented on a constant currency basis.

(1) We define Revenue ex-TAC as our revenue excluding traffic acquisition costs generated over the applicable measurement period. Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution are not measures calculated in accordance with U.S. GAAP. We have included Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution because they are key measures used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of TAC from revenue and review of these measures by region and solution can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region, and Revenue ex-TAC by Solution provide useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Revenue ex-TAC, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution has limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; (b) other companies may report Revenue, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution, or similarly titled measures but define the regions, and product families differently, which reduces their effectiveness as a comparative measure; and (c) other companies may report Revenue ex-TAC or similarly titled measures but calculate them differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Revenue ex-TAC and Revenue, Traffic Acquisition Costs, Revenue ex-TAC by Region and Revenue ex-TAC by Solution alongside our other U.S. GAAP financial results, including revenue. The above tables provide a reconciliation of Revenue ex-TAC to revenue, Revenue ex-TAC by Region to revenue by region and Revenue ex-TAC by Solution to revenue by solution.

(2) Criteo operates as one operating segment. From January 1, 2021 we have disaggregated revenues between Marketing Solutions and Retail Media. A strategic building block of Criteo’s Commerce Media Platform, the Retail Media Platform, introduced in June 2020, is a self-service solution providing transparency, measurement and control to brands and retailers. In all arrangements running on this platform, Criteo recognizes revenue on a net basis, whereas revenue from arrangements running on legacy Retail Media solutions are accounted for on a gross basis. We expect most clients using Criteo’s legacy Retail Media solutions to transition to this platform by the second half of 2022. As new clients onboard and existing clients transition to the Retail Media Platform, Revenue may decline but Revenue ex-TAC margin will increase. Revenue ex-TAC will not be impacted by this transition.
