Note 1. Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements included herein (the "Unaudited Condensed Consolidated Financial Statements") have been prepared by Criteo S.A. pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year.

Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) revenue recognition criteria, (2) allowances for credit losses, (3) research tax credits, (4) income taxes, including i) recognition of deferred tax assets arising from the subsidiaries projected taxable profit for future years, ii) evaluation of uncertain tax positions associated with our transfer pricing policy and iii) recognition of income tax position in respect with tax reforms recently enacted in countries we operate, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill, intangible assets and right of use assets - operating lease, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

The severity, magnitude, duration and after-effects of the COVID-19 pandemic on general economic conditions increase uncertainty associated with these estimates, in particular those related to allowance for credit losses, assumptions used in the valuation of goodwill and estimates relating to income taxes.

There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, except for the update to our existing accounting policy described below:

Revenue Recognition

Principal vs Agent:

For certain customer arrangements, related to transactions using our Retail Media Platform, a new self-service solution providing transparency, measurement and control to our brand and retailer customers, we act as agent, because we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a platform fee based on a percentage of the digital advertising inventory purchased through the use of the platform. Therefore, based on these and other factors, we report the revenue earned and related costs incurred by the Retail Media Platform solution on a net basis.

Accounting Pronouncements Adopted in 2021

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes. The adoption of this new standard did not have a material impact on our consolidated financial statements.

9

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General. The purpose of this update is to modify disclosure requirements for Defined Benefit Plans. It removes requirements to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year among others. It adds disclosure requirements for the items such as an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The adoption of this new standard did not have a material impact on our consolidated financial statements.

Recent Accounting Pronouncements

Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.

Note 2. Significant Events and Transactions of the Period

Restructuring

On February 1, 2021, the Company announced a plan to restructure its workforce across functions and regions to better align with the Company's evolution. We expect the plan will be completed by the end of 2021. The Company recorded $5.2 million of restructuring charges for severance related to this plan in the period ended March 31, 2021. For the three months ended March 31, 2021, $4.0 million was included in Sales and Operations expenses, $1.1 million was included in General and Administrative expenses and $0.1 million was included in Research and Development expenses.

The following table presents the breakdown of restructuring liability as of March 31, 2021, presented as part of employees related payables on the balance sheet:

	(in thousands)
Restructuring liability - January 1, 2021	$	510

Note 3. Financial Instruments

Financial assets

The maximum exposure to credit risk at the end of each reported period is represented by the carrying amount of financial assets and summarized in the following table:

	March 31, 2021		December 31, 2020
	(in thousands)
Trade receivables, net of allowances	416,910		474,055

Other current liabilities	32,693		33,390
Financial liabilities	2,485		3,275
Total	$	510,029	$	547,453

The fair value of financial liabilities approximates the carrying amount, given the nature of the financial liabilities and the maturity of the expected cash flows.

Fair Value Measurements     

We measure the fair value of our cash equivalents and marketable securities, which include interest-bearing bank deposits, as level 2 measurements because they are valued using observable market data.

Financial assets or liabilities include derivative financial instruments used to manage our exposure to the risk of exchange rate fluctuations. These instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

Derivative Financial Instruments

Derivatives consist of foreign currency forward contracts that we use to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the local currency of a subsidiary. We recognize gains and losses on these contracts in financial income (expense), and their position on the balance sheet is based on their fair value at the end of each respective period. These instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

	March 31, 2021		December 31, 2020
	(in thousands)
Derivative Liabilities:
Included in financial liabilities - current portion	$	394	$	925

The fair value of derivative financial instruments approximates the notional amount, given the nature of the derivative financial instruments and the maturity of the expected cash flows.

Cash and Cash Equivalents

The following table presents for each reporting period, the breakdown of cash and cash equivalents:

	March 31, 2021		December 31, 2020
	(in thousands)
Cash equivalents	$	154,885	$	162,457
Cash on hand	365,175		325,554
Total cash and cash equivalents	$	520,060	$	488,011

Cash equivalents are investments in interest–bearing bank deposits which meet ASC 230—Statement of Cash flows criteria: short-term, highly liquid investments, for which the risks of changes in value are considered to be insignificant. Interest-bearing bank deposits are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

For our cash and cash equivalents, the fair value approximates the carrying amount, given the nature of the cash and cash equivalents and the maturity of the expected cash flows.

Marketable Securities

The following table presents for each reporting period, the breakdown of the fair value of marketable securities:

	March 31, 2021		December 31, 2020
	(in thousands)
Securities Available-for-sale

Securities Held-to-maturity
Term Deposits	$	22,586	$	17,271
Total	$	45,867	$	41,809

The gross unrealized gains on our marketable securities were not material as of March 31, 2021.

Term deposits are considered a level 2 financial instrument as they are measured using valuation techniques based on observable market data.

The following table classifies our marketable securities by contractual maturities:

	Held-to-maturity		Available-for-sale

Reversal of provision	3,306		2,989
Currency translation adjustment	658		490
Balance at March 31	$	(38,694)	$	(23,084)

(*) On January 1, 2020, we adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost issued by the Financial Accounting Standards Board (FASB). ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. This results in earlier recognition of credit losses. We adopted ASU 2016-13 effective January 1, 2020 with the cumulative effect of adoption recorded as an adjustment to retained earnings.

We write off accounts receivable balances once the receivables are no longer deemed collectible. During the three month period ended March 31, 2021, and March 31, 2020, the Company recovered $0.5 million, and $0.6 million, respectively, previously written off, and accounted for as a reversal of provision.

As of March 31, 2021 and December 31, 2020 no customer accounted for 10% or more of trade receivables.

Note 10. Share-Based Compensation

The board of directors has been authorized by the general meeting of the shareholders to grant employee warrants (Bons de Souscription de Parts de Créateur d’Entreprise or "BSPCEs"), share options (Options de Souscription d'Actions or "OSAs"), restricted share units ("RSUs") and non-employee warrants (Bons de Souscription d'Actions or "BSAs").

During the three months ended March 31, 2021, there was one grant of RSUs under the Employee Share Option Plan 13 as defined in Note 19 to our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

On February 25, 2021, 96,450 RSUs were granted to Criteo employees subject to continued employment and 235,850 RSUs and 235,848 PSUs were granted to members of the management subject to continued employment.

Note 11. Financial Income and Expenses

The condensed consolidated statements of income line item “Financial income (expense)” can be broken down as follows:

	Three Months Ended
	March 31, 2021		March 31, 2020
	(in thousands)
Financial income from cash equivalents	$	128	$	382
Interest and fees	(540)		(432)
Interest on debt	(417)		(380)
Fees	(123)		(52)
Foreign exchange gain (loss)	(798)		(1,628)
Other financial expense	492		1,344
Total financial expense	$	(718)	$	(334)

The $0.7 million and the $0.3 million financial expenses for the three months ended March 31, 2021 and March 31, 2020, respectively, were driven by the up-front fees amortization, the non-utilization costs and the financial expense relating to our available Revolving Credit Facility (RCF) financing and the recognition of a negative impact of foreign exchange reevaluations net of related hedging. At March 31, 2021, our exposure to foreign currency risk was centralized at Criteo S.A. and hedged using foreign currency swaps or forward purchases or sales of foreign currencies.

23

Note 12. Income Taxes

Breakdown of Income Taxes

The tax provision for interim periods is determined using an estimate of our annual effective tax rate (“AETR”), adjusted for discrete items arising in the period. To calculate our estimated AETR, we estimate our income before taxes and the related tax expense or benefit for the full fiscal year (total of expected current and deferred tax provisions), excluding the effect of significant unusual or infrequently occurring items or comprehensive income items not recognized in the statement of income. Each quarter, we update our estimate of the annual effective tax rate, and if our estimated annual tax rate does change, we make a cumulative adjustment in that quarter. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant volatility due to several factors including our ability to accurately predict our income (loss) before provision for income taxes in multiple jurisdictions and the changes in foreign exchange rates. Our effective tax rate in the future will depend on the portion of our profits earned within and outside of France.

The condensed consolidated statements of income line item “Provision for income taxes” can be broken down as follows:

	Three Months Ended
	March 31, 2021		March 31, 2020
	(in thousands)
Current income tax	$	(5,053)	$	(9,718)
Net change in deferred taxes	(4,998)		2,678
Provision for income taxes	$	(10,051)	$	(7,040)

For the three months ended March 31, 2021 and March 31, 2020, we used an annual estimated tax rate of 30% to calculate the provision for income taxes. The effective tax rate was 30% for the three months ended March 31, 2021 and 2020, respectively.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes and credits of Criteo S.A, Criteo Corp., and Criteo GmbH and Criteo K.K.

Note 13. Earnings Per Share

Basic Earnings Per Share

We calculate basic earnings per share by dividing the net income for the period attributable to shareholders of the Parent by the weighted average number of shares outstanding.

	Three Months Ended
	March 31, 2021		March 31, 2020
Net income attributable to shareholders of Criteo S.A.	$	22,406	$	15,459
Weighted average number of shares outstanding	60,741,674		61,691,001
Basic earnings per share	$	0.37	$	0.25

Diluted Earnings Per Share

We calculate diluted earnings per share by dividing the net income attributable to shareholders of the Parent by the weighted average number of shares outstanding plus any potentially dilutive shares not yet issued from share-based compensation plans (see Note 10). There were no other potentially dilutive instruments outstanding as of March 31, 2020 and March 31, 2021. Consequently, all potential dilutive effects from shares are considered.

For each period presented, a contract to issue a certain number of shares (i.e. share option, non-employee warrant, employee warrant ("BSPCE")) is assessed as potentially dilutive if it is “in the money” (i.e., the exercise or settlement price is lower than the average market price).

	Three Months Ended
	March 31, 2021		March 31, 2020
Net income attributable to shareholders of Criteo S.A.	$	22,406	$	15,459
Weighted average number of shares outstanding of Criteo S.A.	60,741,674		61,691,001
Dilutive effect of :
Restricted share awards ("RSUs")	2,972,382		264,309
Share options and BSPCE	296,071		153,786
Share warrants	67,282		16,486
Weighted average number of shares outstanding used to determine diluted earnings per share	64,077,409		62,125,582
Diluted earnings per share	$	0.35	$	0.25

The weighted average number of securities that were anti-dilutive for diluted EPS for the periods presented but which could potentially dilute EPS in the future are as follows:

	Three Months Ended
	March 31, 2021	March 31, 2020
Restricted share awards	332,300	2,241,223
Share options and BSPCE	—	—
Weighted average number of anti-dilutive securities excluded from diluted earnings per share	332,300	2,241,223

Note 14. Commitments and contingencies

Commitments

Revolving Credit Facilities "RCF", Credit Line Facilities and Bank Overdrafts     

We are party to an RCF with a syndicate of banks which allows us to draw up to €350.0 million ($410.4 million).

We are also party to short-term credit lines and overdraft facilities with HSBC plc, BNP Paribas and LCL with an authorization to draw up to a maximum of €21.5 million ($25.2 million) in the aggregate under the short-term credit lines and overdraft facilities. As of March 31, 2021, we had not drawn on any of these facilities. Any loans or overdrafts under these short-term facilities bear interest based on the one month EURIBOR rate or three month EURIBOR rate. As these facilities are exclusively short-term credit and overdraft facilities, our banks have the ability to terminate such facilities on short notice.

Recently Issued Pronouncements

See "Recently Issued Accounting Standards" under Note 1, "Summary of Significant Accounting Policies," of the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of certain accounting standards that have been issued during 2021.

Use of Non-GAAP Financial Measures

This Form 10-Q includes the following financial measures defined as non-GAAP financial measures by the SEC: Revenue ex-TAC, Adjusted EBITDA and Adjusted Net Income. 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 core geographies. Revenue ex-TAC, Revenue ex-TAC by Region 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 core business and across our core geographies. Accordingly, we believe that Revenue ex-TAC, Revenue ex-TAC by Region, 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, restructuring related and transformation costs, acquisition-related costs and deferred price consideration. Adjusted EBITDA 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- and long-term operational plans. In particular, we believe that by eliminating equity awards compensation expense, pension service costs, restructuring related and transformation costs, acquisition-related costs and deferred price consideration, Adjusted EBITDA can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA provides 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.

30

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, acquisition-related costs and deferred price consideration, and the tax impact of these adjustments. Adjusted Net Income and Adjusted Net Income per diluted share 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, acquisition-related costs and deferred price consideration and the tax impact of these adjustments, Adjusted Net Income and Adjusted Net Income per diluted share can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted Net Income and Adjusted Net Income per diluted share 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.

Please refer to the supplemental financial tables provided for a reconciliation of Revenue ex-TAC to revenue, Adjusted EBITDA to net income, and Adjusted Net Income to net income in each case, the most comparable U.S. GAAP measurement. Our use of non-GAAP financial measures 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: (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, Adjusted EBITDA, Adjusted Net Income, 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.

(3) We define Revenue ex-TAC (Traffic Acquisition Costs) as our revenue excluding traffic acquisition costs, or TAC, generated over the applicable measurement period. Revenue ex-TAC is not a measure calculated in accordance with U.S. GAAP. We have included Revenue ex-TAC in this Form 10-Q 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 TAC from revenue can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that Revenue ex-TAC 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 Revenue ex-TAC 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) 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 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 alongside our other U.S. GAAP financial results, including revenue. The following table presents a reconciliation of Revenue ex-TAC to revenue, the most directly comparable U.S. GAAP measure, for each of the periods indicated:

(4) 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, restructuring related and transformation costs, acquisition-related costs and deferred price consideration, 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 in this Form 10-Q 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, acquisition-related costs and deferred price consideration, 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 core 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 financial results, including net income. The following table presents a reconciliation of Adjusted Net Income to net income, the most directly comparable U.S. GAAP measure, for each of the periods indicated:

(5) 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, restructuring related and transformation costs, acquisition-related costs and deferred price consideration. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. We have included Adjusted EBITDA in this Form 10-Q 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 and long-term operational plans. In particular, we believe that the elimination of equity awards compensation expense, pension service costs, restructuring related and transformation costs,, acquisition-related costs and deferred price consideration in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core 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 other U.S. GAAP financial results, including net income. The following table presents a reconciliation of Adjusted EBITDA to net income, the most directly comparable U.S. GAAP measure, for each of the periods indicated:

(1) Growth at constant currency excludes the impact of foreign currency fluctuations and is computed by applying the 2020 average exchange rates for the relevant period to 2021 figures. We have included revenue at constant currency in this Form 10-Q because it is a key measure used by our management and board of directors to evaluate operating performance. Management reviews and analyzes business results excluding the effect of foreign currency translation because they believe this better represents our underlying business trends.

(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. Over time, we expect most clients using Criteo’s legacy Retail Media solutions to transition to this platform. 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.

Revenue for the three months ended March 31, 2021 increased 7% or 4% on a constant currency basis, (as defined in footnote 1 directly above) to $541.1 million, compared to the three months ended March 31, 2020.

The COVID-19 pandemic impacted our business during most of the quarter, with an estimated net negative impact on revenue of approximately $46 million for the three months ended March 31, 2021, or approximately 9 points of year-over-year growth, as some clients decided to temporarily pause or reduce their campaigns with us.

In the quarter, 81% of the year-over-year increase in revenue was driven by the higher contribution from our existing clients while 19% came from new client additions. We added 266 net new clients year-over-year across regions, while revenue from existing clients increased by 8% at constant currency over the period.

The year-over-year increase in revenue on a constant currency basis was 88% attributable to volume-based drivers of our business (increasing number of impressions delivered and clicks delivered on the advertising banners displayed), and 12% attributable to price-based drivers (increasing average price charged to advertisers).

Marketing Solutions revenue increased 3% (or decreased (0.5)% on a constant currency basis) to $483.2 million for the three months ended March 31, 2021, as increased spend from Retail clients, in particular in our retargeting solution, was partially offset by the negative impact from continued lower spend from Travel clients.

Retail Media revenue increased 72% (or 69% on a constant currency basis) to $57.9 million for the three months ended March 31, 2021, driven by strong performance with large retailers across the U.S. and EMEA, supported by continued solid trends in ecommerce shopping sustained through the COVID-19 pandemic.

Our revenue in the Americas region increased 6% (or 8% on a constant currency basis), including 6% in the U.S., to $203.9 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, driven by positive Retail trends, in particular with large customers across our retargeting and new solutions, continued strong performance of Retail Media, in particular with CPG brands and existing retailers, partially offset by continued negative impact from COVID-19 on Travel and Classifieds clients.

Our revenue in EMEA increased 12% (or 4% on a constant currency basis) to $212.1 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, driven by positive Retail trends, in particular with large customers across our retargeting and new solutions, continued strong performance of Retail Media, partially offset by continued negative impact from COVID-19 on Travel and Classifieds clients.

Our revenue in the Asia-Pacific region increased 3% (or (1)% decrease on a constant currency basis) to $125.1 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, as the continued negative impact from the COVID-19 pandemic on Travel and Classifieds more than offset the recovery of Retail accounts in the region.

Additionally, our $541.1 million of revenue for the three months ended March 31, 2021 was positively impacted by $16.7 million of currency fluctuations, particularly as a result of the depreciation of the Turkish Lira, Russian Ruble, the Brazilian real, partially offset by the appreciation of the Euro and the Japanese Yen, compared to the U.S. dollar.

(1) 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.

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.

Cost of revenue for the three months ended March 31, 2021 increased $31.2 million, or 9%, compared to the three months ended March 31, 2020. This increase was primarily the result of an increase of $30.3 million, or 10% (or 7% on a constant currency basis) in traffic acquisition costs, and an increase of $0.9 million, or 3% (or 2% on a constant currency basis) in other cost of revenue.

The increase in traffic acquisition costs on a constant currency basis related primarily to the 13% increase in the number of impressions we purchased, reflecting our expanding relationships with existing and new publisher partners, in particular through direct connections, to support client demand for advertising campaigns. This increase was partially offset by the (3)% decrease (and (3)% decrease on a constant currency basis) in the average CPM for inventory purchased. This was partly driven by the effectiveness of our Criteo Direct Bidder and direct publisher integrations, which allows us to buy quality inventory directly from large publishers and remove intermediary fees in the process.

Traffic acquisition costs in Marketing Solutions increased by 7%, driven by a 12% increase in the number of impressions we purchased, partially offset by a 5% decrease in the average CPM for inventory purchased.

Traffic acquisition costs in Retail Media increased by 51%, driven by a 53% increase in the number of impressions we purchased, partially offset by a 1% decrease in the average CPM for inventory purchased. As we recognize revenue on a net basis in all arrangements running on the Retail Media platform, we expect our Traffic acquisition costs for Retail Media to decrease over time as our clients are transitioned to the Criteo Retail Media Platform.

40

The increase in other cost of revenue includes a $1.3 million increase in allocated depreciation and amortization expense following the acquisitions of servers and other equipment used in our data centers offset by a $0.4 million decrease in other costs.

We consider Revenue ex-TAC as a key measure of our business activity. Our strategy focuses on maximizing the growth of our Revenue ex-TAC on an absolute basis over maximizing our near-term gross margin. We believe this focus builds sustainable long-term value for our business by fortifying a number of our competitive strengths, including access to advertising inventory, breadth and depth of data and continuous improvement of the Criteo Engine’s performance, allowing it to deliver more relevant advertisements at scale. As a part of this focus, we continue to invest in building relationships with direct publishers and pursuing access to leading advertising exchanges.

Our performance-based business model provides us with significant control over our level of Revenue ex-TAC margin, which we seek to optimize in order to maximize Revenue ex-TAC growth on an absolute basis in accordance with our strategic focus.

(1) We define Revenue ex-TAC as our revenue excluding traffic acquisition costs generated over the applicable measurement period. Revenue ex-TAC and Revenue, Traffic Acquisition Costs and Revenue ex-TAC by Region are not measures calculated in accordance with U.S. GAAP. We have included Revenue ex-TAC and Revenue, Traffic Acquisition Costs and Revenue ex-TAC by Region in this Form 10-Q because they are key measures used by our management and board of directors to evaluate operating performance and generate future operating plans. In particular, we believe that the elimination of TAC from revenue and review of these measures by region can provide useful measures for period-to-period comparisons of our core business. Accordingly, we believe that Revenue ex-TAC and Revenue, Traffic Acquisition Costs and Revenue ex-TAC by Region 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 Revenue ex-TAC and Revenue, Traffic Acquisition Costs and Revenue ex-TAC by Region 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 and Revenue ex-TAC by Region or similarly titled measures but define the regions 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 and Revenue ex-TAC by Region alongside our other U.S. GAAP financial results, including revenue. The above table provides a reconciliation of revenue ex-TAC by region to revenue by region. Please also refer to footnote 3 to the Other Financial and Operating Data table in "Item 2—Management's Discussion and Analysis" of this Form 10-Q for a reconciliation of revenue ex-TAC to revenue, the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP.

Constant Currency Reconciliation

Information in this Form 10-Q with respect to results presented on a constant currency basis was calculated by applying the 2020 average exchange rates for the relevant period to 2021 figures. We have included information with respect to our results presented on a constant currency basis because it is a key measure used by our management and board of directors to evaluate operating performance. Management reviews and analyzes business results excluding the effect of foreign currency translation because they believe this better represents our underlying business trends. Below is a table which reconciles the actual results presented in this section with the results presented on a constant currency basis:  

	Three Months Ended

Research and Development Expenses

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended						% change
	March 31, 2021			March 31, 2020			2021 vs 2020
	(in thousands, except percentages)
Research and development expenses	$	(31,697)		$	(37,515)		(16)%
% of revenue	(6)		%	(7)		%

Research and development expenses for the three months ended March 31, 2021, decreased $(5.8) million or (16)%, compared to the three months ended March 31, 2020. This decrease mainly relates to a decrease in headcount-related costs, and a decrease in depreciation and amortization following the full depreciation of Manage technology in 2020.

Sales and Operations Expenses

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended						% change
	March 31, 2021			March 31, 2020			2021 vs 2020
	(in thousands, except percentages)
Sales and operations expenses	$	(79,354)		$	(84,974)		(7)%
% of revenue	(15)		%	(17)		%

Sales and operations expenses for the three months ended March 31, 2021, decreased $(5.6) million or (7)%, compared to the three months ended March 31, 2020. This decrease is mainly driven by lower bad debt expense, a reduction in headcount-related costs and a lower share-based compensation expense, partially offset by an increase in facilities costs due to early termination of a lease agreement as part of the right-sizing of our real estate footprint.

44

General and Administrative Expenses

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended						% change
	March 31, 2021			March 31, 2020			2021 vs 2020
	(in thousands, except percentages)
General and administrative expenses	$	(33,428)		$	(25,915)		29%
% of revenue	(6)		%	(5)		%

General and administrative expenses for the three months ended March 31, 2021 increased $7.5 million or 29%, compared to the three months ended March 31, 2020. This increase is mainly related to an increase in third-party services as part of our on-going transformation program, a favorable one-time accounting impact in Q1 2020 which lowered the comparable basis, as well as the negative impact of our growing stock price on social charges related to people costs.

Financial Expense

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended						% change
	March 31, 2021			March 31, 2020			2021 vs 2020
	(in thousands, except percentages)
Financial expense	$	(718)		$	(334)		NM
% of revenue	(0.1)		%	(0.1)		%

Financial expense for the three months ended March 31, 2021, respectively, increased by $(0.4) million, compared to the three months ended March 31, 2020. The $0.7 million financial expense for the three months ended March 31, 2021 was driven by the up-front fees amortization, the non-utilization costs and the financial expense relating to our available Revolving Credit Facility (RCF) financing and the recognition of a negative impact of foreign exchange reevaluations net of related hedging. At March 31, 2021, our exposure to foreign currency risk was centralized at Criteo S.A. and hedged using foreign currency swaps or forward purchases or sales of foreign currencies.

45

Provision for Income Taxes

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended						% change
	March 31, 2021			March 31, 2020			2021 vs 2020
	(in thousands, except percentages)
Provision for income taxes	$	(10,051)		$	(7,040)		43%
% of revenue	(2)		%	(1)		%
Effective tax rate	30		%	30		%

For the three ended months March 31, 2021 and March 31, 2020, respectively, we used an annual estimated tax rate of 30% to calculate the provision for income taxes. The effective tax rate was 30% for both the three months ended March 31, 2021 and March 31, 2020.

Net Income

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

	Three Months Ended					% change
	March 31, 2021			March 31, 2020		2021 vs 2020
	(in thousands, except percentages)
Net income	$	23,450		16,428		43%
% of revenue	4		%	3	%

Net income for the three months ended March 31, 2021, increased $7.0 million, or 43%, compared to the three months ended March 31, 2020. This increase was the result of the factors discussed above, in particular, a $10.4 million increase in income from operations partially offset by a $(0.4) million increase in financial expense and a $(3.0) million increase in provision for income taxes compared to the three months ended March 31, 2020.

46

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operating activities. We have never declared or paid any cash dividends on our ordinary shares. We do not anticipate paying cash dividends on our equity securities in the foreseeable future. In 2018, we completed an $80 million share repurchase program. In July 2019, the Board of Directors authorized a new share repurchase program of up to $80 million of the Company’s outstanding American Depositary Shares, which we completed in February 2020. In April 2020, the Board of Directors authorized a new share repurchase program of up to $30 million of the Company's outstanding American Depositary Shares, which we completed in July 2020. In February 2021, the Board of Directors approved a new, long-term share repurchase program of up $100 million of the Company's outstanding American Depositary Shares, for which the duration is estimated to be until February, 2023. Other than these repurchase programs, we intend to retain all available funds from any future earnings to fund our growth. As discussed in Note 14 to the unaudited condensed consolidated financial statements in Item 1 to this Form 10-Q, we are party to several loan agreements and revolving credit facilities with third-party financial institutions.

Our cash and cash equivalents are invested primarily in demand deposit accounts that are currently providing only a minimal return. Our cash and cash equivalents at March 31, 2021 were held for working capital and general corporate purposes, which could include acquisitions, and amounted to $520.1 million as of March 31, 2021. The $32.0 million increase in cash and cash equivalents compared with December 31, 2020 primarily resulted from $77.4 million in cash from operating activities, partially offset by $(17.0) million in cash used for investing activities and $(3.4) million in cash used for financing activities over the period. The cash used for financing activities is mainly related to $(4.9) million cash used for the share repurchase programs. In addition, the increase in cash includes a $(24.9) million negative impact of changes in foreign exchange rates on our cash position over the period. We do not enter into investments for trading or speculative purposes. Our policy is to invest any cash in excess of our immediate requirements in investments designed to preserve the principal balance and provide liquidity. Accordingly, our cash and cash equivalents are invested primarily in demand deposit accounts that are currently providing only a minimal return.

Furthermore, the Company has immediate access to an additional €350 million from the Revolving Credit Facility, which, combined with its cash position, marketable securities and treasury shares as of March 31, 2021, provides total liquidity in excess of $1.0 billion. Overall, we believe that our current financial liquidity, combined with our expected cash-flow generation in 2021, enables financial flexibility.

Operating and Capital Expenditure Requirements

For the three months ended March 31, 2021 and 2020, our capital expenditures were $13.8 million and $11.7 million, respectively. During the three months ended March 31, 2021, these capital expenditures were primarily related to the acquisition of data center and server equipment, and IT systems. We expect our capital expenditures to remain at, or slightly above, 3% of revenue for 2021, as we plan to continue to build and maintain additional data center equipment capacity in all regions and significantly increase our redundancy capacity to strengthen our infrastructure.

We believe our existing cash balances will be sufficient to meet our anticipated cash requirements through at least the next 12 months.  

Our future working capital requirements will depend on many factors, including the rate of our revenue growth, the amount and timing of our investments in personnel and capital equipment, and the timing and extent of our introduction of new products and product enhancements.

If our cash and cash equivalents balances and cash flows from operating activities are insufficient to satisfy our liquidity requirements, we may need to raise additional funds through equity, equity-linked or debt financings to support our operations, and such financings may not be available to us on acceptable terms, or at all. We may also need to raise additional funds in the event we determine in the future to effect one or more acquisitions of businesses, technologies, assets or products.

If we are unable to raise additional funds when needed, our operations and ability to execute our business strategy could be adversely affected. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to holders of our equity securities and could contain covenants that restrict our operations. Any additional equity financing will be dilutive to our shareholders.

47

Off-Balance Sheet Arrangements

We do not have any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. We therefore believe that we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Historical Cash Flows

The following table sets forth our cash flows for the three month period ended March 31, 2021 and 2020:

	Three Months Ended
	March 31, 2021		March 31, 2020
	(in thousands)
Cash from operating activities	$	77,362	$	56,743
Cash used for investing activities	$	(17,032)	$	(10,848)
Cash used for financing activities	$	(3,416)	$	(18,761)

Operating Activities

Cash provided by operating activities is primarily impacted by the increase in the number of clients using our solution and by the amount of cash we invest in personnel to support the anticipated growth of our business. Cash provided by operating activities has typically been generated from net income and by changes in our operating assets and liabilities, particularly in the areas of accounts receivable and accounts payable and accrued expenses, adjusted for certain non-cash and non-operating items such as depreciation, amortization and share-based compensation, deferred tax assets and income taxes.

For the three months ended March 31, 2021, net cash provided by operating activities was $77.4 million and consisted of net income of $23.5 million, $30.0 million in adjustments for certain non-cash and non-operating items and changes in working capital of $23.9 million. Adjustments for certain non-operating items primarily consisted of depreciation and amortization expense of $17.2 million, equity awards compensation expense of $7.2 million, $3.9 million on disposal of non-current assets and $5.0 million changes in deferred tax assets, partially offset by a $3.4 million change in income taxes. The $23.9 million increase in cash from changes in working capital primarily consisted of a $47.2 million decrease in trade receivables, partially offset by a $5.1 million increase in other current assets including prepaid expenses and VAT receivables, a $3.1 million change in lease liabilities and right of use assets, a $10.6 million decrease in trade payables, and a $4.5 million decrease in other current liabilities such as payroll and payroll related expenses and value-added tax ("VAT") payables.

Investing Activities

Our investing activities to date have consisted primarily of purchases of servers and other data-center equipment. For the three months ended March 31, 2021, net cash used for investing activities was $17.0 million and primarily consisted of $13.8 million in capital expenditures, mainly comprised of purchases of servers and other data-center equipment and capitalized costs, and a $3.3 million change in other non-current financial assets.

Financing Activities

For the three months ended March 31, 2021, net cash used for financing activities was $3.4 million, resulting mainly from a $4.9 million payment for our share repurchase program, $0.4 million change in other financial liabilities and a $0.2 million repayment of borrowings partially offset by $2.1 million of proceeds from capital increase.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk

We are mainly exposed to foreign currency exchange rate fluctuations. There have been no material changes to our exposure to market risk during the three months ended March 31, 2021.

For a description of our foreign exchange risk, please see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - B. Liquidity and Capital Resources" in our Annual Report on Form 10-K for the year ended December 31, 2020.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Based on their evaluation as of March 31, 2021, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) were effective to provide reasonable assurance that (i) the information required to be disclosed in our reports filed or submitted under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and (ii) such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

Limitation on Effectiveness of Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Criteo have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies and procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error of fraud may occur and not be detected.

51

PART II

Item 1.    Legal Proceedings.

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, financial condition, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors.

You should carefully consider the risks described under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020. These risks and uncertainties are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. If any such risks materialize, our business, financial condition and results of operations could be materially harmed and the trading price of our American Depositary Shares could decline. These risks are not exclusive and additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. There have been no material changes to the Risk Factors described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Purchases of Equity Securities by the issuer and Affiliated Purchasers

The following table provides certain information with respect to our purchases of our ADSs during the first fiscal quarter of 2021:

Period	Total Number of Shares Purchased(1)	Average Price Paid per Share(2)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs(1)	Approximate Dollar Value of Shares That May Yet Be Purchased Under the Plans or Programs(1)

Total	149,960	$	32.87	149,960	—

(1) On February 5, 2021, Criteo's Board of Directors authorized a share repurchase program of up to $100.0 million of the Company's outstanding American Depositary Shares. The Company intends to use repurchased shares to satisfy employee equity plan vesting in lieu of issuing new shares, and potentially in connection with M&A transactions. The repurchase program commenced in March 2021 and will be concluded in March 2023.

(2) Average price paid per share excludes any broker commissions paid.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements included herein (the "Unaudited Condensed Consolidated Financial Statements") have been prepared by Criteo S.A. pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year.

Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) revenue recognition criteria, (2) allowances for credit losses, (3) research tax credits, (4) income taxes, including i) recognition of deferred tax assets arising from the subsidiaries projected taxable profit for future years, ii) evaluation of uncertain tax positions associated with our transfer pricing policy and iii) recognition of income tax position in respect with tax reforms recently enacted in countries we operate, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill, intangible assets and right of use assets - operating lease, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

The severity, magnitude, duration and after-effects of the COVID-19 pandemic on general economic conditions increase uncertainty associated with these estimates, in particular those related to allowance for credit losses, assumptions used in the valuation of goodwill and estimates relating to income taxes.

There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, except for the update to our existing accounting policy described below:

Revenue Recognition

Principal vs Agent:

For certain customer arrangements, related to transactions using our Retail Media Platform, a new self-service solution providing transparency, measurement and control to our brand and retailer customers, we act as agent, because we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a platform fee based on a percentage of the digital advertising inventory purchased through the use of the platform. Therefore, based on these and other factors, we report the revenue earned and related costs incurred by the Retail Media Platform solution on a net basis.

Accounting Pronouncements Adopted in 2021

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes. The adoption of this new standard did not have a material impact on our consolidated financial statements.

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General. The purpose of this update is to modify disclosure requirements for Defined Benefit Plans. It removes requirements to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year among others. It adds disclosure requirements for the items such as an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The adoption of this new standard did not have a material impact on our consolidated financial statements.

Recent Accounting Pronouncements

Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.

Restructuring

On February 1, 2021, the Company announced a plan to restructure its workforce across functions and regions to better align with the Company's evolution. We expect the plan will be completed by the end of 2021. The Company recorded $5.2 million of restructuring charges for severance related to this plan in the period ended March 31, 2021. For the three months ended March 31, 2021, $4.0 million was included in Sales and Operations expenses, $1.1 million was included in General and Administrative expenses and $0.1 million was included in Research and Development expenses.

The following table presents the breakdown of restructuring liability as of March 31, 2021, presented as part of employees related payables on the balance sheet:

The maximum exposure to credit risk at the end of each reported period is represented by the carrying amount of financial assets and summarized in the following table:

	March 31, 2021		December 31, 2020
	(in thousands)
Trade receivables, net of allowances	416,910		474,055

The fair value of financial liabilities approximates the carrying amount, given the nature of the financial liabilities and the maturity of the expected cash flows.

Fair Value Measurements     

We measure the fair value of our cash equivalents and marketable securities, which include interest-bearing bank deposits, as level 2 measurements because they are valued using observable market data.

Financial assets or liabilities include derivative financial instruments used to manage our exposure to the risk of exchange rate fluctuations. These instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

Derivative Financial Instruments

Derivatives consist of foreign currency forward contracts that we use to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the local currency of a subsidiary. We recognize gains and losses on these contracts in financial income (expense), and their position on the balance sheet is based on their fair value at the end of each respective period. These instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

The fair value of derivative financial instruments approximates the notional amount, given the nature of the derivative financial instruments and the maturity of the expected cash flows.

Cash and Cash Equivalents

Cash on hand	365,175		325,554
Total cash and cash equivalents	$	520,060	$	488,011

Cash equivalents are investments in interest–bearing bank deposits which meet ASC 230—Statement of Cash flows criteria: short-term, highly liquid investments, for which the risks of changes in value are considered to be insignificant. Interest-bearing bank deposits are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

For our cash and cash equivalents, the fair value approximates the carrying amount, given the nature of the cash and cash equivalents and the maturity of the expected cash flows.

(*) On January 1, 2020, we adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost issued by the Financial Accounting Standards Board (FASB). ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. This results in earlier recognition of credit losses. We adopted ASU 2016-13 effective January 1, 2020 with the cumulative effect of adoption recorded as an adjustment to retained earnings.

We write off accounts receivable balances once the receivables are no longer deemed collectible. During the three month period ended March 31, 2021, and March 31, 2020, the Company recovered $0.5 million, and $0.6 million, respectively, previously written off, and accounted for as a reversal of provision.

As of March 31, 2021 and December 31, 2020 no customer accounted for 10% or more of trade receivables.

Share-Based Compensation

The board of directors has been authorized by the general meeting of the shareholders to grant employee warrants (Bons de Souscription de Parts de Créateur d’Entreprise or "BSPCEs"), share options (Options de Souscription d'Actions or "OSAs"), restricted share units ("RSUs") and non-employee warrants (Bons de Souscription d'Actions or "BSAs").

During the three months ended March 31, 2021, there was one grant of RSUs under the Employee Share Option Plan 13 as defined in Note 19 to our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

On February 25, 2021, 96,450 RSUs were granted to Criteo employees subject to continued employment and 235,850 RSUs and 235,848 PSUs were granted to members of the management subject to continued employment.

There have been no changes in the vesting and method of valuation of the BSPCEs, OSAs, RSUs, or BSAs from what was disclosed in Note 19 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021.

The $0.7 million and the $0.3 million financial expenses for the three months ended March 31, 2021 and March 31, 2020, respectively, were driven by the up-front fees amortization, the non-utilization costs and the financial expense relating to our available Revolving Credit Facility (RCF) financing and the recognition of a negative impact of foreign exchange reevaluations net of related hedging. At March 31, 2021, our exposure to foreign currency risk was centralized at Criteo S.A. and hedged using foreign currency swaps or forward purchases or sales of foreign currencies.

Income Taxes

Breakdown of Income Taxes

The tax provision for interim periods is determined using an estimate of our annual effective tax rate (“AETR”), adjusted for discrete items arising in the period. To calculate our estimated AETR, we estimate our income before taxes and the related tax expense or benefit for the full fiscal year (total of expected current and deferred tax provisions), excluding the effect of significant unusual or infrequently occurring items or comprehensive income items not recognized in the statement of income. Each quarter, we update our estimate of the annual effective tax rate, and if our estimated annual tax rate does change, we make a cumulative adjustment in that quarter. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant volatility due to several factors including our ability to accurately predict our income (loss) before provision for income taxes in multiple jurisdictions and the changes in foreign exchange rates. Our effective tax rate in the future will depend on the portion of our profits earned within and outside of France.

The condensed consolidated statements of income line item “Provision for income taxes” can be broken down as follows:

Provision for income taxes	$	(10,051)	$	(7,040)

For the three months ended March 31, 2021 and March 31, 2020, we used an annual estimated tax rate of 30% to calculate the provision for income taxes. The effective tax rate was 30% for the three months ended March 31, 2021 and 2020, respectively.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes and credits of Criteo S.A, Criteo Corp., and Criteo GmbH and Criteo K.K

Net income attributable to shareholders of Criteo S.A.	$	22,406	$	15,459

Basic earnings per share	$	0.37	$	0.25

Diluted Earnings Per Share

We calculate diluted earnings per share by dividing the net income attributable to shareholders of the Parent by the weighted average number of shares outstanding plus any potentially dilutive shares not yet issued from share-based compensation plans (see Note 10). There were no other potentially dilutive instruments outstanding as of March 31, 2020 and March 31, 2021. Consequently, all potential dilutive effects from shares are considered.

For each period presented, a contract to issue a certain number of shares (i.e. share option, non-employee warrant, employee warrant ("BSPCE")) is assessed as potentially dilutive if it is “in the money” (i.e., the exercise or settlement price is lower than the average market price).

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited condensed consolidated financial statements included herein (the "Unaudited Condensed Consolidated Financial Statements") have been prepared by Criteo S.A. pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year.

Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) revenue recognition criteria, (2) allowances for credit losses, (3) research tax credits, (4) income taxes, including i) recognition of deferred tax assets arising from the subsidiaries projected taxable profit for future years, ii) evaluation of uncertain tax positions associated with our transfer pricing policy and iii) recognition of income tax position in respect with tax reforms recently enacted in countries we operate, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill, intangible assets and right of use assets - operating lease, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

The severity, magnitude, duration and after-effects of the COVID-19 pandemic on general economic conditions increase uncertainty associated with these estimates, in particular those related to allowance for credit losses, assumptions used in the valuation of goodwill and estimates relating to income taxes.

There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, except for the update to our existing accounting policy described below:

Revenue Recognition

Revenue Recognition

Principal vs Agent:

For certain customer arrangements, related to transactions using our Retail Media Platform, a new self-service solution providing transparency, measurement and control to our brand and retailer customers, we act as agent, because we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a platform fee based on a percentage of the digital advertising inventory purchased through the use of the platform. Therefore, based on these and other factors, we report the revenue earned and related costs incurred by the Retail Media Platform solution on a net basis.

Accounting Pronouncements Adopted in 2021 and Recent Accounting Pronouncements

Accounting Pronouncements Adopted in 2021

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes. The adoption of this new standard did not have a material impact on our consolidated financial statements.

Effective January 1, 2021, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General. The purpose of this update is to modify disclosure requirements for Defined Benefit Plans. It removes requirements to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year among others. It adds disclosure requirements for the items such as an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The adoption of this new standard did not have a material impact on our consolidated financial statements.

Recent Accounting Pronouncements

Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.

(*) On January 1, 2020, we adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost issued by the Financial Accounting Standards Board (FASB). ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. This results in earlier recognition of credit losses. We adopted ASU 2016-13 effective January 1, 2020 with the cumulative effect of adoption recorded as an adjustment to retained earnings.
