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 filed on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 1, 2019. 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 doubtful accounts, (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 of the tax reform in France voted in December 2018, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill and intangible assets, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

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, 2018, except for the accounting pronouncements adopted below.

Accounting Pronouncements adopted in 2019

Effective January 1, 2019, we have adopted the Financial Accounting Standards Board, ("FASB") Accounting Standards Update ("ASU") 842 No. 2016-02, Leases (Topic 842) (ASU 2016-02), which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet for operating leases with terms of more than 12 months, in addition to those currently recorded. In August 2018, the FASB issued ASU 2018-11, Target Improvements to ASC 842, which included an option not to restate comparative periods in transition and use the effective date of ASC 842, Leases, as the date of the initial application of transition, which we elected. Prior periods have not been adjusted and continue to be accounted for in accordance with ASC 840. As a result of adopting ASU 842, we recognized total operating lease liabilities of $223.5 million and operating right-of-use assets of $204.3 million as of January 1, 2019. The adoption of ASC 842 had an immaterial impact on our condensed consolidated statements of income and our condensed consolidated statement of cash flows for the three month period ended March 31, 2019. Refer to Note 8. Leases, for additional information and required disclosures.

Effective January 1, 2019, we have adopted ASU 2018 - 07, Improvements to Non-Employee Sharebased Payment Accounting. The amendments in this ASU expands Topic 718 to include share base payments for goods or services to non employees. The adoption of ASU 2018-07 did not have a material impact on our financial position or results of operations.

8

Recently Issued Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-04 Goodwill and Other (Topic 350). ASU 2017-04 simplifies the subsequent measurement of goodwill and reduces the cost and complexity of evaluating goodwill for impairment. It eliminates the need for entities to calculate the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under this amendment, an entity will perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value. This update will be effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on our financial position or results of operations.

In August 2017, the FASB issued ASU 2017-12 Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12was issued with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements as well as to simplify the application of hedge accounting guidance in current GAAP. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2017-12 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 2018 - 13, Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirement for Fair Value Measurement. This ASU modifies disclosure requirements for Fair Value including 1) removing existing disclosure requirements such as reasons for transfers from 1 to 2 level, policy of timing of transfers 2) modifying existing disclosure requirements, such as a rollforward of level 3 assets, investments in entities that calculate net asset value, and the measurement uncertainty disclosure 3) Adds additional disclosures such as changes in unrealized gains and losses in OCI, and the range and weight of significant unobservable inputs. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2018-13 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 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. We intend to adopt the standard on the effective date of January 1, 2021. The adoption of ASU 2018-14 is not expected to have a material impact on our financial position or results of operations but may have an impact on our disclosures.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal Use Software - Customer’s Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU was issued to clarify the accounting for implementation costs incurred for SaaS agreements. Previously the guidance only referred to development of internal use software and the accounting for SaaS agreements was not clarified. This ASU states that the implementation costs should be capitalized. The ASU will be effective for periods after December 15, 2019. We are currently evaluating the impact on our financial position, results of operations, and statement of cash flows.

Note 2. Significant Events and Transactions of the Period

Change in estimated useful life of servers and other data center equipment

On January 1, 2019 we revised our estimate of the useful life of all servers and other equipment used in our data centers from 3 to 5 years. This change in estimate was determined based on a revised commissioning plan which extends the period equipment is used to 5 years prior to disposal. This resulted in an increase in income from operations of $10.8 million, increase net income of $9.2 million, or $0.14 per share, from that which would have been reported had the previous expected useful life of 3 years been used.

Share repurchase program

On October 25, 2018 Criteo's Board of Directors authorized a share repurchase program of up to $80.0 million of the Company’s outstanding American Depositary Shares. As of December 31, 2018, 3.5 million shares were held as treasury shares.

On February 8, 2019, the Board of Directors authorized the reduction of capital resulting in the formal retirement of 1.6 million treasury shares. As of March 31, 2019, we have 1.7 million treasury shares remaining which may be used primarily to satisfy the company's obligations under its employee equity plans upon RSU vestings in lieu of issuing new shares.

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:

	December 31, 2018		March 31, 2019
	(in thousands)
Trade receivables, net of allowance	473,901		386,792
Other taxes	53,338		56,828
Other current assets	22,816		24,737
Non-current financial assets	20,460		20,331

Credit Risk

We maintain an allowance for estimated credit losses. During the period ended March 31, 2019 and the year ended December 31, 2018, our net change in allowance for doubtful accounts was $0.7 million and $5.1 million, respectively.

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

Trade Receivables

Credit risk is defined as an unexpected loss in cash and earnings if the client is unable to pay its obligations in due time. We perform internal ongoing credit risk evaluations of our clients. When a possible risk exposure is identified, we require prepayments.

As of December 31, 2018 and March 31, 2019, no customer accounted for 10% or more of trade receivables.

Financial Liabilities

Other current liabilities	47,115		37,256
Financial liabilities	3,508		3,882
Total	$	597,469	$	508,712

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

We are party to several loan agreements and a revolving credit facility, or RCF, with third-party financial institutions. There have been no significant changes from what was disclosed in Note 13 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Fair Value Measurements     

We measure the fair value of our cash equivalents, 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.

	December 31, 2018		March 31, 2019
	(in thousands)
Derivative Assets:
Included in other current assets	$	1,703	$	—
Derivative Liabilities:
Included in financial liabilities - current portion	$	—	$	603

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

Cash and Cash Equivalents

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.

Note 8. Leases

On January 1, 2019, we adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) which requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet.

We have adopted Topic 842 effective January 1, 2019 on a modified retrospective basis and elected not to restate comparative periods. We chose to use certain practical expedients offered by the standard including:

• We did not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases, or the initial direct costs for any existing leases.

• We do not recognize a lease liability or right of use asset for leases with a term of 12 months or less, and

• We used hindsight in determining the lease term.

We lease space under non-cancellable operating leases for our offices as well as our data centers. Our office leases typically include free rent periods or rent escalation periods, and may also include leasehold improvement incentives. Leases for data centers may also include free rent periods or rent escalation periods. These leases typically do not include residual value guarantees. Both office and data center leases may contain both lease components (rent) and non-lease components (maintenance, electrical costs, and other service charges). Non-lease components are accounted for separately.

Both office and data center leases typically contain options to renew, and/or early terminate. We have evaluated management's expectations for these options as of March 31, 2019. Options have been included in the lease term if management has determined it is reasonably certain it will be exercised.

Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate at lease commencement to determine the present value of future payments. We have a centralized treasury function, and the majority of our leases are negotiated and signed by representatives of Criteo SA. As such, the incremental borrowing rate of Criteo SA is used for all of our contracts. It is then adjusted in consideration of the currency of the lease and the lease term as of the lease commencement date.

Lease expense is recognized for minimum lease payments on a straight-line basis over the lease term. Variable costs are expensed in the period incurred. Variable expenses include changes in indexation. Leases for data centers may have variable costs based on electrical usage.

The components of lease expense are as follows:

	Three Months Ended
	March 31, 2019
	Offices			Data Centers		Total
	(in thousands)
Lease expense	$	8,340		$	5,187	$	13,527

Sublease income	(1,076		)	—		(1,076		)
Total operating lease expense	$	8,189		$	5,831	$	14,020

	(in thousands)
Cash paid for amounts included in the measurement of lease liabilities
Cash flow for operating activities	$	(13,964	)
Right of use assets obtained in exchange for new operating lease liabilities	$	10,926

17

As of March 31, 2019, we have additional operating leases, primarily for offices, that have not yet commenced which will result in additional operating lease liabilities and right of use assets of approximately $14.0 million. These operating leases will commence between 2019 and 2020.

For periods prior to January 1, 2019, we accounted for our lease commitments in accordance with ASC 840. We recognized rent expense for leases on a straight-line basis over the life of the lease. For the three months ended March 31, 2018, we recognized expense for office leases of $9.7 million and data centers costs of $12.3 million. The rent expense recognized in prior periods included amounts which are now considered non-lease components such as maintenance services and electricity charges.

Reduction of London office space

We evaluate our right of use assets for impairment. As of March 31, 2019, management has implemented a plan to reduce the occupied space of the London Office. In accordance with ASC 842, we have reviewed the right-of-use asset due to the London Office lease for impairment resulting in a $1.9 million impairment charge for the three months ended March 31, 2019. This charge was recognized in Sales and Operations expenses in our condensed consolidated statement of income.

Note 9. Revenue

Revenue Recognition

We sell personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. Historically, the Criteo model has focused solely on converting our clients' website visitors into customers, enabling us to charge our clients only when users engage with an ad we deliver, usually by clicking on it. More recently, we have expanded our solutions to address a broader range of marketing goals for our clients.

We offer two families of solutions to our commerce and brand clients:

• Criteo Marketing Solutions allow commerce companies to address multiple marketing goals by engaging their consumers with personalized ads across the web, mobile and offline store environments.

• Criteo Retail Media solutions allow retailers to generate advertising revenues from consumer brands, and/or to drive sales for themselves, by monetizing their data and audiences through personalized ads, either on their own digital property or on the open Internet, that address multiple marketing goals.

In conjunction with expanding our solutions, we have also started expanding our pricing models to now include a combination of cost-per-install and cost-per-impression for selected new solutions, in addition to cost-per-click.

We recognize revenues when we transfer control of promised services directly to our clients or to advertising agencies, which we collectively refer to as our clients, in an amount that reflects the consideration to which we expect to be entitled to in exchange for those services.

For campaigns priced on a cost-per-click and cost-per-install basis, we bill our clients when a user clicks on an advertisement we deliver or installs an application by clicking on an advertisement we delivered, respectively. For these pricing models, we recognize revenue when a user clicks on an advertisement or installs an application.     

For campaigns priced on a cost-per-impression basis, we bill our clients based on the number of times an advertisement is displayed to a user. For this pricing model, we recognize revenue when an advertisement is displayed.

We act as principal in our arrangements because (i) we control the advertising inventory (spaces on websites) before it is transferred to our clients; (ii) we bear sole responsibility for fulfillment of the advertising promise and inventory risks and (iii) we have full discretion in establishing prices. Therefore, based on these factors, we report revenue earned and the related costs incurred on a gross basis.

Disaggregation of revenue

The following tables disclose our consolidated revenue for each geographical area for each of the reported periods. Revenue by geographical area is based on the location of advertisers’ campaigns.

The following table presents our revenues disaggregated by geographical area:

	Americas		EMEA		Asia-Pacific		Total
For the three months ended	(in thousands)
March 31, 2018	$	212,695	$	222,611	$	128,858	$	564,164
March 31, 2019	$	217,993	$	209,643	$	130,487	$	558,123

Excluding our historical solution for driving Conversion through Criteo Marketing Solutions (formerly called Criteo Dynamic Retargeting), no individual solution accounted for more than 10% of total consolidated revenue for the periods presented.

19

Customer Credit Notes

We offer credit notes to certain customers as a form of incentive, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and they are recognized as a reduction of revenue. We believe that there will not be significant changes to our estimates of variable consideration.

Deferred Revenues

We record deferred revenues when cash payments are received or due in advance of our performance. Our payment terms vary depending on the service or the type of customer. For certain customers, we require payment before the services are delivered.

Practical Expedients

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and operating expenses.

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, 2019, there was one grant of RSUs under the Employee Share Option Plan 11 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, 2018.

• On March 1, 2019, 202,180 RSUs were granted to Criteo employees 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, 2018, filed with the SEC on March 1, 2019.

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, 2018			March 31, 2019
	(in thousands)
Financial income from cash equivalents	$	225		$	177
Interest and fees	(556		)	(523		)
Interest on debt	(487		)	(430		)
Fees	(69		)	(93		)
Foreign exchange gain (loss)	(972		)	(1,598		)
Other financial expense	(22		)	(30		)
Total financial income (expense)	$	(1,325	)	$	(1,974	)

The $2.0 million financial expense for the three months ended March 31, 2019 was driven by the non-utilization costs incurred as part of our available RCF financing and the recognition of negative impact of foreign exchange reevaluations net of related hedging. At March 31, 2019, 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.

The $1.3 million financial expense for the three months ended March 31, 2018 was driven by the non-utilization costs incurred as part of our available RCF financing and hedging costs related to an intra-group position between Criteo S.A. and its U.S. subsidiary in the context of the funding of the HookLogic acquisition.

Note 12. Income Taxes

Breakdown of Income Taxes

Our tax provision for interim periods is determined using an estimate of our annual effective tax rate (“AETR”), adjusted for discrete items arising in that quarter. 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, 2018			March 31, 2019
	(in thousands)
Current income tax	$	(15,532	)	$	(15,934	)
Net change in deferred taxes	3,146			5,916
Provision for income taxes	$	(12,386	)	$	(10,018	)

For the three months ended March 31, 2018 and 2019, we used an annual estimated tax rate of 37% and 30%, respectively, to calculate the provision for income taxes. The effective tax rate was 37% and 32% for the three months ended March 31, 2018 and 2019, respectively. The difference between the annual estimated tax rate and the effective tax rate for three months ended March 31, 2019 was due to the tax impact of discrete items such as share-based compensation in the United States. Discrete items were immaterial for the three months ended March 31, 2018 resulting in no difference between the annual estimated tax rate and the effective tax rate.

For the three months ended March 31, 2019, our estimated effective tax rate includes in particular our preliminary estimates for the tax reform in France voted in December 2018. For the three months ended March 31, 2018, our estimated annual effective tax rate included our preliminary estimates for the impact of the U.S. Tax Cuts and Jobs Act (the "Tax Act") which was enacted on December 22, 2017 and introduces significant changes to U.S. income tax law. Effective in 2018, the Tax Act reduces the U.S. federal income tax rate from 35% to 21% and creates new taxes on certain related-party payments, referred to as a base erosion anti-avoidance tax, or “BEAT”. Our estimates are preliminary, and our effective tax rate may be impacted as more information becomes available regarding the tax reform.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes and credits of Criteo GMBH, Criteo do Brasil LTDA, and Criteo B.V.. The current tax liabilities refers mainly to the net corporate tax payables of Criteo K.K.

Ongoing tax inspection in the United States

On September 27, 2017, we received a draft notice of proposed adjustment "NOPA" from the Internal Revenue Service ("IRS") audit of Criteo Corp. for the year ended December 31, 2014, confirmed by the definitive notice dated February 8, 2018. Although we disagree with the IRS's position and are currently contesting this issue, the ultimate resolution of this litigation is uncertain and, if resolved in a manner unfavorable to us, could result in an additional federal tax liability of an estimated maximum aggregate amount of approximately $15.0 million, excluding related fees, interest and penalties.

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, 2018		March 31, 2019
Net income attributable to shareholders of Criteo S.A.	$	19,809	$	19,120
Weighted average number of shares outstanding	66,160,375		64,336,777
Basic earnings per share	$	0.30	$	0.30

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, 2018 and 2019. 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 ("BSA"), restricted share unit ("RSU") or 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, 2018		March 31, 2019
Net income attributable to shareholders of Criteo S.A.	$	19,809	$	19,120
Weighted average number of shares outstanding of Criteo S.A.	66,160,375		64,336,777
Dilutive effect of :
Restricted share awards ("RSUs")	865,039		1,317,350
Share options and BSPCE	407,806		336,647
Share warrants	36,518		50,522
Weighted average number of shares outstanding used to determine diluted earnings per share	67,469,738		66,041,296
Diluted earnings per share	$	0.29	$	0.29

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, 2018	March 31, 2019
Restricted share awards	1,901,128	482,152
Share options and BSPCE	—	65,500
Weighted average number of anti-dilutive securities excluded from diluted earnings per share	1,901,128	547,652

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and the audited consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission, or "SEC", on March 1, 2019.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations," included in our Annual Report filed on Form 10-K for the year ended December 31, 2018, except for the adoption of ASC 842 as of January 1, 2019. Please refer to Note 1,"Summary of Significant Accounting Policies," of the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of the changes in accounting policies due to the adoption of this standard.

On January 1, 2019 we have revised our estimate of the useful life of all servers and other equipment used in our data centers from 3 to 5 years. This change in estimate was determined based on a revised commissioning plan which extends the period equipment is used to 5 years prior to disposal. This resulted in an increase in income from operations of $10.8 million, increase net income of $9.2 million, or $0.14 per share, from that which would have been reported had the previous expected useful life of 3 years been used.

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 2019.

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 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 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.

28

Adjusted Net Income is our net income adjusted to eliminate the impact of equity awards compensation expense, amortization of acquisition-related intangible assets, restructuring 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 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.

⁽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 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.

⁽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 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.

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.

⁽¹⁾ Growth at constant currency excludes the impact of foreign currency fluctuations and is computed by applying the 2018 average exchange rates for the relevant period to 2019 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.

Revenue for the three months ended March 31, 2019decreased to $558.1 million, decreasing by (1)% (or increasing by 3% on a constant currency basis, as defined in footnote 1 directly above), compared to the three months ended March 31, 2018. Revenue from new clients contributed 59.8% to the year-over-year revenue growth at constant currency, while revenue from existing clients contributed 40.2%. We added 845 net new clients across regions and client sizes over the period, a lower volume than the prior period, primarily driven by our increased focus on higher-value midmarket clients until we roll out our self-service onboarding module to address smaller midmarket prospects. Revenue from existing clients grew over 2% at constant currency over the period, largely driven by the broader adoption of our new solutions addressing new marketing goals as well as Criteo Retail Media.

The year-over-year increase at constant currency was the result of our growth across all regions. Revenue in the Americas region increased2% (or 4% on a constant currency basis, including 5% in the U.S.) to $218.0 million for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. Growth was driven by increased spend from existing clients using our Criteo Marketing Solutions to address new marketing goals, particularly Consideration, the acceleration of our midmarket business driven by larger midmarket clients, continued good traction in our Criteo Retail Media business in the U.S., as well as improving performance in Brazil.

35

Revenue in EMEA decreased(6)% (or increased 3% on a constant currency basis) to $209.6 million for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. This increase at constant currency was largely driven by accelerated growth in our midmarket business, as well as the positive traction of our Criteo Marketing Solutions, particularly to address the Consideration marketing goal, partly offset by a continued short-term headwind related to GDPR implementation across the region.

Revenue in the Asia-Pacific region increased1% (or 4% on a constant currency basis) to $130.5 million for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. This increase was the result of strong growth in Korea, driven by both existing large customers and midmarket customers, increased spend from large existing clients in Japan, offset by a slow-down in new client acquisition in Japan and slower business in India and South-East Asia.

Additionally, our $558.1 million of revenue for the three months ended March 31, 2019 was negatively impacted by $24.0 million as a result of changes in foreign currency against the U.S. dollar compared to the three months ended March 31, 2018.

The year-over-year growth in revenue on a constant currency basis is entirely attributable to an increased number of clicks delivered on the advertising banners displayed by us as well as the increased number of impressions delivered by us.

Cost of Revenue

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019
	(in thousands, except percentages)
Traffic acquisition costs	$	(323,746	)	$	(322,429	)	(0.4)%
Other cost of revenue	$	(30,059	)	$	(26,045	)	(13)%

% of revenue	(63		)%	(62		)%
Gross profit %	37		%	38		%

Cost of revenue for the three months ended March 31, 2019decreased$(5.3) million, or (2)%, compared to the three months ended March 31, 2018. This decrease was primarily the result of a decrease of $(1.3) million, or (0.4)% (or an increase of 4% on a constant currency basis), in traffic acquisition costs and a $(4.0) million, or (13)% (or (11)% on a constant currency basis), decrease in other cost of revenue.

The increase in traffic acquisition costs related primarily to an increase of 7% in the number of impressions we purchased, reflecting our expanding relationships with existing and new publisher partners to support the growth in our client demand for advertising campaigns. Over the period, the average cost per thousand impressions (or "CPM"), decreased by (6.6)% (or (2.6)% on a constant currency basis), driven by a combination of factors, including the effectiveness of our Criteo Direct Bidder, which allows us to buy quality inventory directly from large publishers in the web and in apps, and remove intermediary fees in the process, as well as the growing share of in-app inventory in our business, which has inventory costs that tend to be slightly lower on average than that in the web browser environment.

The decrease in other cost of revenue includes a $6.1 million decrease in allocated depreciation and amortization expense following the changes in our estimation of the useful life of the servers and other equipment used in our datacenters from 3 to 5 years, partially offset by a $1.3 million increase in hosting costs, and a net $0.8 million increase in other costs including the provision for the expected Digital Tax in France and Italy ($1.4 million).

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.

36

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.

Revenue, Traffic Acquisition Costs and Revenue ex-TAC by Region

The following table sets forth our revenue, traffic acquisition costs and Revenue ex-TAC by geographic region, including the Americas (North and South America), Europe, Middle East and Africa, or EMEA, and Asia-Pacific.

⁽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 2018 average exchange rates for the relevant period to 2019 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:

Research and Development Expenses

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019
	(in thousands, except percentages)
Research and development expenses	$	(45,318	)	$	(46,577	)	3%
% of revenue	(8		)%	(8		)%

Research and development expenses for the three months ended March 31, 2019increased$1.3 million, or 3%, compared to the three months ended March 31, 2018. This increase mainly related to an increase in amortization of acquisition-related intangible assets and consulting fees, partially offset by an increase in the French Research Tax Credit.

Sales and Operations Expenses

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019

Sales and operations expenses	$	(95,649	)	$	(95,909	)	0.3%
% of revenue	(17		)%	(17		)%

Sales and operations expenses for the three months ended March 31, 2019increased$0.3 million, or 0.3%, compared to the three months ended March 31, 2018. This increase mainly related to an impairment charge for our London office lease, an increase in headcount-related costs, partially offset by a decrease in bad debt expense and operating taxes.

General and Administrative Expenses

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019
	(in thousands, except percentages)
General and administrative expenses	$	(34,591	)	$	(33,770	)	(2)%
% of revenue	(6		)%	(6		)%

General and administrative expenses for the three months ended March 31, 2019decreased$(0.8) million, or (2)%, compared to the three months ended March 31, 2018. This decrease was the result of a lower equity compensation expense, partially offset by the proceeds from disposal of the HookLogic travel business in March 31, 2018, and an increase in consulting fees for process optimization projects.

Financial Income (Expense)

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019
	(in thousands,  except percentages)
Financial income (expense)	$	(1,325	)	$	(1,974	)	49%
% of revenue	(0.2		)%	(0.4		)%

The Financial expense for the three months ended March 31, 2019 increased by $0.6 million, or 49%, compared to the three months ended March 31, 2018. The $2.0 million financial expense for the three months ended March 31, 2019 was driven by the non-utilization costs incurred as part of 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, 2019, 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.

The $1.3 million financial expense for the three months ended March 31, 2018 was driven by the non-utilization costs incurred as part of our available RCF financing and hedging costs related to an intra-group position between Criteo S.A. and its U.S. subsidiary in the context of the funding of the HookLogic acquisition.

Provision for Income Taxes

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended						% change
	March 31, 2018			March 31, 2019			2018 vs 2019
	(in thousands, except percentages)
Provision for income taxes	$	(12,386	)	$	(10,018	)	(19)%
% of revenue	(2		)%	(2		)%
Effective tax rate	37		%	32		%

For the three months ended March 31, 2018 and March 31, 2019, we used an annual estimated tax rate of 37% and 30% respectively to calculate the provision for income taxes. The effective tax rate was 37% and 32% for the three months ended March 31, 2018 and 2019, respectively. The difference between the annual estimated tax rate and the effective tax rate for three months ended March 31, 2019 was due to the tax impact of discrete items such as share-based compensation in the United States. Discrete items were immaterial for the three months ended March 31, 2018 resulting in no difference between the annual estimated tax rate and the effective tax rate.

Net Income

Three months ended March 31, 2019 compared to the three months ended March 31, 2018

	Three Months Ended					% change
	March 31, 2018			March 31, 2019		2018 vs 2019
	(in thousands,  except percentages)
Net income	$	21,090		21,401		1%
% of revenue	4		%	4	%

Net income for the three months ended March 31, 2019increased$0.3 million, or 1%, compared to the three months ended March 31, 2018. This increase was the result of the factors discussed above, in particular, a $1.4 million decrease in income from operations and a $0.6 million increase in financial expense offset by a $2.3 million decrease in provision for income taxes compared to the three months ended March 31, 2018.

41

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 and intend to retain all available funds and any future earnings to fund our growth. As discussed in Note 3 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, 2019 were held for working capital and general corporate purposes, which could include acquisitions, and amounted to $395.8 million as of March 31, 2019. The $31.3 million increase in cash and cash equivalents compared with December 31, 2018 primarily resulted from $67.2 million in cash from operating activities, partially offset by a $29.0 million in cash used for investing activities and $0.2 million used for financing activities over the period. The cash used for investing activities is mainly related to $23.7 million in capital expenditures and a $5.4 million following a business acquisition that was not material to our consolidated financial statements. The cash used for financing activities is primarily related to $0.2 million of repayment of borrowings. In addition, the increase in cash includes a $6.6 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.

Operating and Capital Expenditure Requirements

For the three months ended March 31, 2018 and 2019, our capital expenditures were $32.6 million and $23.7 million, respectively. In 2019, 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 the level of approximately 5% of revenue for 2019, 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.

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.

42

Historical Cash Flows

The following table sets forth our cash flows for the three month period ended March 31, 2018 and 2019 :

	Three Months Ended
	March 31, 2018			March 31, 2019
	(in thousands)
Cash from operating activities	$	84,527		$	67,220
Cash used in investing activities	$	(43,490	)	$	(29,041	)
Cash from (used for) financing activities	$	16,773		$	(191	)

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 and infrastructure 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, 2019, net cash provided by operating activities was $67.2 million and consisted of net income of $21.4 million, $42.9 million in adjustments for certain non-cash and non-operating items and changes in working capital of $20.8 million partially offset by $17.9 million of income taxes paid during the first three months of 2019. Adjustments for certain operating items primarily consisted of depreciation and amortization expense of $19.6 million, equity awards compensation expense of $13.9 million, $15.9 million of accrued income taxes partially offset by $0.7 million for other items and by $5.9 million of changes in deferred tax assets. The $20.8 million increase in cash from changes in working capital primarily consisted of a $86.0 million decrease in trade receivables, a $2.4 million increase in other current liabilities such as payroll and payroll related expenses and value-added tax ("VAT") payables, partially offset by a $58.5 million decrease in trade payables, a $6.0 million increase in other current assets including prepaid expenses and VAT receivables, and a $3.2 million decrease in change of lease liabilities and right of use assets.

Investing Activities

Our investing activities to date have consisted primarily of purchases of property and equipment and business acquisitions.

For the three months ended March 31, 2019, net cash used in investing activities was $29.0 million and consisted of $23.7 million for purchases of property and equipment and a $5.4 million payment following a business acquisition that was not material to our consolidated financial statements.

Financing Activities

For the three months ended March 31, 2019, net cash used for financing activities was $0.2 million resulting from repayment of borrowings.

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 first three months ended period March 31, 2019.

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, 2018.

A 10% increase or decrease of the Pound Sterling, the Euro, the Japanese yen or the Brazilian real against the U.S. dollar would have impacted the Condensed Consolidated Statements of Income as follows:

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Based on their evaluation as of March 31, 2019, 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.

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.

45

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 below and under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018. 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 ADSs 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, 2018.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

In these notes, Criteo S.A. is referred to as the "Parent" company and together with its subsidiaries, collectively, as "Criteo," the "Company," the "Group," or "we".

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 filed on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 1, 2019. 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 doubtful accounts, (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 of the tax reform in France voted in December 2018, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill and intangible assets, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

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, 2018, except for the accounting pronouncements adopted below.

Accounting Pronouncements adopted in 2019

Effective January 1, 2019, we have adopted the Financial Accounting Standards Board, ("FASB") Accounting Standards Update ("ASU") 842 No. 2016-02, Leases (Topic 842) (ASU 2016-02), which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet for operating leases with terms of more than 12 months, in addition to those currently recorded. In August 2018, the FASB issued ASU 2018-11, Target Improvements to ASC 842, which included an option not to restate comparative periods in transition and use the effective date of ASC 842, Leases, as the date of the initial application of transition, which we elected. Prior periods have not been adjusted and continue to be accounted for in accordance with ASC 840. As a result of adopting ASU 842, we recognized total operating lease liabilities of $223.5 million and operating right-of-use assets of $204.3 million as of January 1, 2019. The adoption of ASC 842 had an immaterial impact on our condensed consolidated statements of income and our condensed consolidated statement of cash flows for the three month period ended March 31, 2019. Refer to Note 8. Leases, for additional information and required disclosures.

Effective January 1, 2019, we have adopted ASU 2018 - 07, Improvements to Non-Employee Sharebased Payment Accounting. The amendments in this ASU expands Topic 718 to include share base payments for goods or services to non employees. The adoption of ASU 2018-07 did not have a material impact on our financial position or results of operations.

Recently Issued Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-04 Goodwill and Other (Topic 350). ASU 2017-04 simplifies the subsequent measurement of goodwill and reduces the cost and complexity of evaluating goodwill for impairment. It eliminates the need for entities to calculate the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under this amendment, an entity will perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value. This update will be effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on our financial position or results of operations.

In August 2017, the FASB issued ASU 2017-12 Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12was issued with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements as well as to simplify the application of hedge accounting guidance in current GAAP. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2017-12 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 2018 - 13, Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirement for Fair Value Measurement. This ASU modifies disclosure requirements for Fair Value including 1) removing existing disclosure requirements such as reasons for transfers from 1 to 2 level, policy of timing of transfers 2) modifying existing disclosure requirements, such as a rollforward of level 3 assets, investments in entities that calculate net asset value, and the measurement uncertainty disclosure 3) Adds additional disclosures such as changes in unrealized gains and losses in OCI, and the range and weight of significant unobservable inputs. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2018-13 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 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. We intend to adopt the standard on the effective date of January 1, 2021. The adoption of ASU 2018-14 is not expected to have a material impact on our financial position or results of operations but may have an impact on our disclosures.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal Use Software - Customer’s Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU was issued to clarify the accounting for implementation costs incurred for SaaS agreements. Previously the guidance only referred to development of internal use software and the accounting for SaaS agreements was not clarified. This ASU states that the implementation costs should be capitalized. The ASU will be effective for periods after December 15, 2019. We are currently evaluating the impact on our financial position, results of operations, and statement of cash flows.

Significant Events and Transactions of the Period

Change in estimated useful life of servers and other data center equipment

On January 1, 2019 we revised our estimate of the useful life of all servers and other equipment used in our data centers from 3 to 5 years. This change in estimate was determined based on a revised commissioning plan which extends the period equipment is used to 5 years prior to disposal. This resulted in an increase in income from operations of $10.8 million, increase net income of $9.2 million, or $0.14 per share, from that which would have been reported had the previous expected useful life of 3 years been used.

Share repurchase program

On October 25, 2018 Criteo's Board of Directors authorized a share repurchase program of up to $80.0 million of the Company’s outstanding American Depositary Shares. As of December 31, 2018, 3.5 million shares were held as treasury shares.

On February 8, 2019, the Board of Directors authorized the reduction of capital resulting in the formal retirement of 1.6 million treasury shares. As of March 31, 2019, we have 1.7 million treasury shares remaining which may be used primarily to satisfy the company's obligations under its employee equity plans upon RSU vestings in lieu of issuing new shares.

Credit Risk

We maintain an allowance for estimated credit losses. During the period ended March 31, 2019 and the year ended December 31, 2018, our net change in allowance for doubtful accounts was $0.7 million and $5.1 million, respectively.

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

Trade Receivables

Credit risk is defined as an unexpected loss in cash and earnings if the client is unable to pay its obligations in due time. We perform internal ongoing credit risk evaluations of our clients. When a possible risk exposure is identified, we require prepayments.

As of December 31, 2018 and March 31, 2019, no customer accounted for 10% or more of trade receivables.

We are party to several loan agreements and a revolving credit facility, or RCF, with third-party financial institutions. There have been no significant changes from what was disclosed in Note 13 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Fair Value Measurements     

We measure the fair value of our cash equivalents, 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.

Leases [Abstract]

Leases

Leases

On January 1, 2019, we adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) which requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet.

We have adopted Topic 842 effective January 1, 2019 on a modified retrospective basis and elected not to restate comparative periods. We chose to use certain practical expedients offered by the standard including:

• We did not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases, or the initial direct costs for any existing leases.

• We do not recognize a lease liability or right of use asset for leases with a term of 12 months or less, and

• We used hindsight in determining the lease term.

We lease space under non-cancellable operating leases for our offices as well as our data centers. Our office leases typically include free rent periods or rent escalation periods, and may also include leasehold improvement incentives. Leases for data centers may also include free rent periods or rent escalation periods. These leases typically do not include residual value guarantees. Both office and data center leases may contain both lease components (rent) and non-lease components (maintenance, electrical costs, and other service charges). Non-lease components are accounted for separately.

Both office and data center leases typically contain options to renew, and/or early terminate. We have evaluated management's expectations for these options as of March 31, 2019. Options have been included in the lease term if management has determined it is reasonably certain it will be exercised.

Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate at lease commencement to determine the present value of future payments. We have a centralized treasury function, and the majority of our leases are negotiated and signed by representatives of Criteo SA. As such, the incremental borrowing rate of Criteo SA is used for all of our contracts. It is then adjusted in consideration of the currency of the lease and the lease term as of the lease commencement date.

Lease expense is recognized for minimum lease payments on a straight-line basis over the lease term. Variable costs are expensed in the period incurred. Variable expenses include changes in indexation. Leases for data centers may have variable costs based on electrical usage.

The components of lease expense are as follows:

	Three Months Ended

As of March 31, 2019, we have additional operating leases, primarily for offices, that have not yet commenced which will result in additional operating lease liabilities and right of use assets of approximately $14.0 million. These operating leases will commence between 2019 and 2020.

For periods prior to January 1, 2019, we accounted for our lease commitments in accordance with ASC 840. We recognized rent expense for leases on a straight-line basis over the life of the lease. For the three months ended March 31, 2018, we recognized expense for office leases of $9.7 million and data centers costs of $12.3 million. The rent expense recognized in prior periods included amounts which are now considered non-lease components such as maintenance services and electricity charges.

Reduction of London office space

We evaluate our right of use assets for impairment. As of March 31, 2019, management has implemented a plan to reduce the occupied space of the London Office. In accordance with ASC 842, we have reviewed the right-of-use asset due to the London Office lease for impairment resulting in a $1.9 million impairment charge for the three months ended March 31, 2019. This charge was recognized in Sales and Operations expenses in our condensed consolidated statement of income.

Revenue Recognition

We sell personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. Historically, the Criteo model has focused solely on converting our clients' website visitors into customers, enabling us to charge our clients only when users engage with an ad we deliver, usually by clicking on it. More recently, we have expanded our solutions to address a broader range of marketing goals for our clients.

We offer two families of solutions to our commerce and brand clients:

• Criteo Marketing Solutions allow commerce companies to address multiple marketing goals by engaging their consumers with personalized ads across the web, mobile and offline store environments.

• Criteo Retail Media solutions allow retailers to generate advertising revenues from consumer brands, and/or to drive sales for themselves, by monetizing their data and audiences through personalized ads, either on their own digital property or on the open Internet, that address multiple marketing goals.

In conjunction with expanding our solutions, we have also started expanding our pricing models to now include a combination of cost-per-install and cost-per-impression for selected new solutions, in addition to cost-per-click.

We recognize revenues when we transfer control of promised services directly to our clients or to advertising agencies, which we collectively refer to as our clients, in an amount that reflects the consideration to which we expect to be entitled to in exchange for those services.

For campaigns priced on a cost-per-click and cost-per-install basis, we bill our clients when a user clicks on an advertisement we deliver or installs an application by clicking on an advertisement we delivered, respectively. For these pricing models, we recognize revenue when a user clicks on an advertisement or installs an application.     

For campaigns priced on a cost-per-impression basis, we bill our clients based on the number of times an advertisement is displayed to a user. For this pricing model, we recognize revenue when an advertisement is displayed.

We act as principal in our arrangements because (i) we control the advertising inventory (spaces on websites) before it is transferred to our clients; (ii) we bear sole responsibility for fulfillment of the advertising promise and inventory risks and (iii) we have full discretion in establishing prices. Therefore, based on these factors, we report revenue earned and the related costs incurred on a gross basis.

Disaggregation of revenue

The following tables disclose our consolidated revenue for each geographical area for each of the reported periods. Revenue by geographical area is based on the location of advertisers’ campaigns.

The following table presents our revenues disaggregated by geographical area:

	Americas		EMEA		Asia-Pacific		Total
For the three months ended	(in thousands)
March 31, 2018	$	212,695	$	222,611	$	128,858	$	564,164
March 31, 2019	$	217,993	$	209,643	$	130,487	$	558,123

Excluding our historical solution for driving Conversion through Criteo Marketing Solutions (formerly called Criteo Dynamic Retargeting), no individual solution accounted for more than 10% of total consolidated revenue for the periods presented.

Customer Credit Notes

We offer credit notes to certain customers as a form of incentive, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and they are recognized as a reduction of revenue. We believe that there will not be significant changes to our estimates of variable consideration.

Deferred Revenues

We record deferred revenues when cash payments are received or due in advance of our performance. Our payment terms vary depending on the service or the type of customer. For certain customers, we require payment before the services are delivered.

Practical Expedients

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and operating expenses.

Total financial income (expense)	$	(1,325	)	$	(1,974	)

The $2.0 million financial expense for the three months ended March 31, 2019 was driven by the non-utilization costs incurred as part of our available RCF financing and the recognition of negative impact of foreign exchange reevaluations net of related hedging. At March 31, 2019, 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.

The $1.3 million financial expense for the three months ended March 31, 2018 was driven by the non-utilization costs incurred as part of our available RCF financing and hedging costs related to an intra-group position between Criteo S.A. and its U.S. subsidiary in the context of the funding of the HookLogic acquisition.

Income Taxes

Income Taxes

Breakdown of Income Taxes

Our tax provision for interim periods is determined using an estimate of our annual effective tax rate (“AETR”), adjusted for discrete items arising in that quarter. 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, 2018			March 31, 2019
	(in thousands)
Current income tax	$	(15,532	)	$	(15,934	)
Net change in deferred taxes	3,146			5,916
Provision for income taxes	$	(12,386	)	$	(10,018	)

For the three months ended March 31, 2018 and 2019, we used an annual estimated tax rate of 37% and 30%, respectively, to calculate the provision for income taxes. The effective tax rate was 37% and 32% for the three months ended March 31, 2018 and 2019, respectively. The difference between the annual estimated tax rate and the effective tax rate for three months ended March 31, 2019 was due to the tax impact of discrete items such as share-based compensation in the United States. Discrete items were immaterial for the three months ended March 31, 2018 resulting in no difference between the annual estimated tax rate and the effective tax rate.

For the three months ended March 31, 2019, our estimated effective tax rate includes in particular our preliminary estimates for the tax reform in France voted in December 2018. For the three months ended March 31, 2018, our estimated annual effective tax rate included our preliminary estimates for the impact of the U.S. Tax Cuts and Jobs Act (the "Tax Act") which was enacted on December 22, 2017 and introduces significant changes to U.S. income tax law. Effective in 2018, the Tax Act reduces the U.S. federal income tax rate from 35% to 21% and creates new taxes on certain related-party payments, referred to as a base erosion anti-avoidance tax, or “BEAT”. Our estimates are preliminary, and our effective tax rate may be impacted as more information becomes available regarding the tax reform.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes and credits of Criteo GMBH, Criteo do Brasil LTDA, and Criteo B.V.. The current tax liabilities refers mainly to the net corporate tax payables of Criteo K.K.

Ongoing tax inspection in the United States

On September 27, 2017, we received a draft notice of proposed adjustment "NOPA" from the Internal Revenue Service ("IRS") audit of Criteo Corp. for the year ended December 31, 2014, confirmed by the definitive notice dated February 8, 2018. Although we disagree with the IRS's position and are currently contesting this issue, the ultimate resolution of this litigation is uncertain and, if resolved in a manner unfavorable to us, could result in an additional federal tax liability of an estimated maximum aggregate amount of approximately $15.0 million, excluding related fees, interest and penalties.

Earnings Per Share

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, 2018		March 31, 2019
Net income attributable to shareholders of Criteo S.A.	$	19,809	$	19,120
Weighted average number of shares outstanding	66,160,375		64,336,777
Basic earnings per share	$	0.30	$	0.30

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, 2018 and 2019. 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 ("BSA"), restricted share unit ("RSU") or 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).

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2019

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 filed on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 1, 2019. 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 doubtful accounts, (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 of the tax reform in France voted in December 2018, (5) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (6) assumptions used in the valuation of goodwill and intangible assets, and (7) assumptions used in the valuation model to determine the fair value of share-based compensation plan.

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, 2018, except for the accounting pronouncements adopted below

Recently Issued Accounting Standards

Accounting Pronouncements adopted in 2019

Effective January 1, 2019, we have adopted the Financial Accounting Standards Board, ("FASB") Accounting Standards Update ("ASU") 842 No. 2016-02, Leases (Topic 842) (ASU 2016-02), which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet for operating leases with terms of more than 12 months, in addition to those currently recorded. In August 2018, the FASB issued ASU 2018-11, Target Improvements to ASC 842, which included an option not to restate comparative periods in transition and use the effective date of ASC 842, Leases, as the date of the initial application of transition, which we elected. Prior periods have not been adjusted and continue to be accounted for in accordance with ASC 840. As a result of adopting ASU 842, we recognized total operating lease liabilities of $223.5 million and operating right-of-use assets of $204.3 million as of January 1, 2019. The adoption of ASC 842 had an immaterial impact on our condensed consolidated statements of income and our condensed consolidated statement of cash flows for the three month period ended March 31, 2019. Refer to Note 8. Leases, for additional information and required disclosures.

Effective January 1, 2019, we have adopted ASU 2018 - 07, Improvements to Non-Employee Sharebased Payment Accounting. The amendments in this ASU expands Topic 718 to include share base payments for goods or services to non employees. The adoption of ASU 2018-07 did not have a material impact on our financial position or results of operations.

Recently Issued Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-04 Goodwill and Other (Topic 350). ASU 2017-04 simplifies the subsequent measurement of goodwill and reduces the cost and complexity of evaluating goodwill for impairment. It eliminates the need for entities to calculate the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under this amendment, an entity will perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value. This update will be effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on our financial position or results of operations.

In August 2017, the FASB issued ASU 2017-12 Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12was issued with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements as well as to simplify the application of hedge accounting guidance in current GAAP. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2017-12 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 2018 - 13, Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirement for Fair Value Measurement. This ASU modifies disclosure requirements for Fair Value including 1) removing existing disclosure requirements such as reasons for transfers from 1 to 2 level, policy of timing of transfers 2) modifying existing disclosure requirements, such as a rollforward of level 3 assets, investments in entities that calculate net asset value, and the measurement uncertainty disclosure 3) Adds additional disclosures such as changes in unrealized gains and losses in OCI, and the range and weight of significant unobservable inputs. We intend to adopt the standard on the effective date of January 1, 2020. The adoption of ASU 2018-13 is not expected to have a material impact on our financial position or results of operations.

In August 2018, the FASB issued ASU 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. We intend to adopt the standard on the effective date of January 1, 2021. The adoption of ASU 2018-14 is not expected to have a material impact on our financial position or results of operations but may have an impact on our disclosures.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal Use Software - Customer’s Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU was issued to clarify the accounting for implementation costs incurred for SaaS agreements. Previously the guidance only referred to development of internal use software and the accounting for SaaS agreements was not clarified. This ASU states that the implementation costs should be capitalized. The ASU will be effective for periods after December 15, 2019. We are currently evaluating the impact on our financial position, results of operations, and statement of cash flows.

Revenue

Excluding our historical solution for driving Conversion through Criteo Marketing Solutions (formerly called Criteo Dynamic Retargeting), no individual solution accounted for more than 10% of total consolidated revenue for the periods presented.

Customer Credit Notes

We offer credit notes to certain customers as a form of incentive, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and they are recognized as a reduction of revenue. We believe that there will not be significant changes to our estimates of variable consideration.

Deferred Revenues

We record deferred revenues when cash payments are received or due in advance of our performance. Our payment terms vary depending on the service or the type of customer. For certain customers, we require payment before the services are delivered.

Practical Expedients

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and operating expenses.

Revenue Recognition

We sell personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. Historically, the Criteo model has focused solely on converting our clients' website visitors into customers, enabling us to charge our clients only when users engage with an ad we deliver, usually by clicking on it. More recently, we have expanded our solutions to address a broader range of marketing goals for our clients.

We offer two families of solutions to our commerce and brand clients:

• Criteo Marketing Solutions allow commerce companies to address multiple marketing goals by engaging their consumers with personalized ads across the web, mobile and offline store environments.

• Criteo Retail Media solutions allow retailers to generate advertising revenues from consumer brands, and/or to drive sales for themselves, by monetizing their data and audiences through personalized ads, either on their own digital property or on the open Internet, that address multiple marketing goals.

In conjunction with expanding our solutions, we have also started expanding our pricing models to now include a combination of cost-per-install and cost-per-impression for selected new solutions, in addition to cost-per-click.

We recognize revenues when we transfer control of promised services directly to our clients or to advertising agencies, which we collectively refer to as our clients, in an amount that reflects the consideration to which we expect to be entitled to in exchange for those services.

For campaigns priced on a cost-per-click and cost-per-install basis, we bill our clients when a user clicks on an advertisement we deliver or installs an application by clicking on an advertisement we delivered, respectively. For these pricing models, we recognize revenue when a user clicks on an advertisement or installs an application.     

For campaigns priced on a cost-per-impression basis, we bill our clients based on the number of times an advertisement is displayed to a user. For this pricing model, we recognize revenue when an advertisement is displayed.

We act as principal in our arrangements because (i) we control the advertising inventory (spaces on websites) before it is transferred to our clients; (ii) we bear sole responsibility for fulfillment of the advertising promise and inventory risks and (iii) we have full discretion in establishing prices. Therefore, based on these factors, we report revenue earned and the related costs incurred on a gross basis.
