NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Criteo S.A. is a global technology company specialized in digital performance marketing. We strive to deliver post-click sales to our advertiser clients at scale and according to the client's targeted return on investment. 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". The Company uses its proprietary predictive software algorithms coupled with its deep insights into expressed consumer intent and purchasing habits to price and deliver highly relevant and personalized performance advertisements to consumers in real time.

Note 1. Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements included herein 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, 2016, filed with the SEC on March 1, 2017. 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) the recognition of revenue and particularly the determination as to whether revenue should be reported on a gross or a net basis; (2) the evaluation of our trade receivables and the recognition of a valuation allowance for doubtful accounts; (3) the recognition and measurement of goodwill and intangible assets and particularly costs capitalized in relation to our customized internal-use software; (4) the measurement of share-based compensation and (5) the tax provision determination and particularly the estimate of our annual effective tax rate based on applicable tax rates.

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, 2016 that have had a material impact on our unaudited condensed consolidated financial statements and related notes.

Accounting Pronouncements adopted in 2017

From January 1, 2017, we adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting issued by the Financial Accounting Standards Board (FASB), which among other items, simplifies certain aspects of the accounting for share-based payment transactions to employees. The new standard particularly requires excess tax benefits and tax deficiencies to be recorded in the statements of income as a component of the provision for income taxes when stock awards vest or are settled. The effective date is January 1, 2017. Upon adoption, a cumulative effect of $10.0 million of this change has been recognized through retained earnings. The adoption of the standard also resulted in a current year tax expense of $1.4 million which previously would have been recognized in the current period in additional paid-in capital.

6

Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) ("ASU 2017-01") the purpose of which is to change the definition of a business to assist entities in evaluating when a set of transferred assets and activities is a business. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of ASU 2017-01 is not expected to have a material impact on our financial position or results of operations.

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 March 2017, FASB issued ASU 2017-07 Compensation-Retirements Benefits (Topic 715). ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendments in ASU 2017-07 improve the consistency, transparency, and usefulness of financial information to users that have communicated that the service cost component generally is analyzed differently from the other components of net benefit cost. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-07 is not expected to have a material impact on our financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09 Compensation - Stock Compensation (Topic 718). ASU 2017-09 was issued to provide clarity and reduce diversity in practice and complexity when applying the guidance in Topic 718 to a change in terms or conditions of a share based payment award. The amendments are effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted and should be applied prospectively to an award modified on or after the adoption date. To date, Criteo has not yet had any modifications of its share-based awards. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-09 is not expected to have a material impact on our financial position or results of operations.

Note 2. Significant Events and Transactions of the Period

Restructuring of our China Operations

In May 2017, the Company announced it would no longer continue to serve the domestic market in China and would refocus its China operations entirely on the export business.

For the three months and six months ended June 30, 2017, $2.5 million was included in Other Cost of Revenue, $0.7 million in Sales and Operations expenses, and $0.1 million was included in General and Administrative expenses.

The following table summarizes restructuring activities as of June 30, 2017 included in other current liabilities on the balance sheet:

Note 3. Financial Instruments

Credit Risk

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, 2016		June 30, 2017
Cash and cash equivalents	$	270,317	$	308,185
Trade receivables, net of allowance	397,244		370,052
Other taxes	52,942		46,514
Other current assets	19,340		28,270
Non-current financial assets	17,029		18,824
Total	$	756,872	$	771,845

As of December 31, 2016 and June 30, 2017, no customer accounted for 10% or more of trade receivables.

We perform ongoing credit evaluations of our customers and do not require collateral. We maintain an allowance for estimated credit losses. During the twelve-month period ended December 31, 2016 and the six-month period ended June 30, 2017, our allowance for doubtful accounts increased by $5.4 million and $3.1 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.

Fair Value Measurements     

We measure the fair value of our cash equivalents, which include money market funds and interest bearing deposits, as level 1 and level 2 measurements because they are valued using quoted market prices and observable market data, respectively.

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.

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.

For each period presented, the aging of trade receivables and allowances for potential losses is as follows:

	December 31, 2016									June 30, 2017

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.

Cash and Cash Equivalents

Cash and cash equivalents include investments in money market funds and 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. Money market funds are considered level 1 financial instruments as they are valued using quoted market prices. Interest-bearing bank deposits are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

Note 6. Intangible assets

The changes in intangible assets since December 31, 2016 mainly relate to purchase accounting adjustments to technology and customer relationships following the finalization of the Monsieur Drive purchase price allocation as well as the preliminary purchase price allocation for HookLogic in which technology and customer relationships were identified as intangible assets. A change in this preliminary valuation may also impact the income tax related accounts. The amounts shown below may change in the near term as management continues to assess the fair value of acquired assets and liabilities within the twelve-month purchase price allocation period.

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"), free shares/restricted share units ("RSUs") and non-employee warrants (Bons de Souscription d'Actions or "BSAs").

During the six months ended June 30, 2017, there were three grants of RSUs and one grant of OSAs under the Employee Share Option Plan 9 and one grant of BSAs under the Plan F, 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, 2016.

• On March 1, 2017, 231,460 RSUs were granted to Criteo employees subject to continued employment and 10,825 BSAs were granted to a board member subject to continued engagement on the board of directors.

• On April 27, 2017, 139,386 RSUs were granted to Criteo employees subject to continued employment.

• On June 27, 2017, 135,500 RSUs were granted to senior management subject to achievement of internal performance objectives and continued employment. Based on the assumptions known as of June 30, 2016, we determined share-based compensation expense by applying the probability of performance objectives completion. In addition, on June 27, 2017, 896,586 RSUs and 355,010 OSAs 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, 2016, filed with the SEC on March 1, 2017.

The $2.1 million financial expense for the three months ended June 30, 2017 was driven by the hedging cost 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 in November 2016 and the non-utilization fees incurred as part of our available RCF financing. The $0.1 million financial expense for the three months ended June 30, 2016 was mainly the result of a neutral impact of foreign exchange reevaluations and related hedging together with the recognition of the fees related to the revolving credit facility entered into in September 2015 (as amended in March 2017).

Total financial income (expense)	$	(1,412	)	$	(4,427	)

The $4.4 million financial expense for the six months ended June 30, 2017 was driven by the interest accrued as a result of the $75 million drawn on the revolving credit facility entered into in September 2015 (as amended in March 2017) and the hedging cost related to an intra-group position between Criteo S.A. and its U.S. subsidiary, both in the context of the funding of the HookLogic acquisition in November 2016, as well as the non-utilization fees incurred as part of our available RCF financing. The $1.4 million financial expense for the six months ended June 30, 2016 was mainly a result of the recognition of the negative impact of foreign exchange reevaluations and related hedging recorded during the first quarter, together with the fees related to the revolving credit facility entered into in September 2015 (as amended in March 2017).

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 changes, 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:

	Six Months Ended
	June 30, 2016			June 30, 2017
	(in thousands)
Current income tax	$	(16,818	)	$	(20,271	)
France	(8,172		)	(7,289		)
International	(8,646		)	(12,982		)
Net change in deferred taxes	4,424			12,405
France	4,216			(944		)
International	208			13,349
Provision for income taxes	$	(12,394	)	$	(7,866	)

For the six months ended June 30, 2016 and 2017, we utilized an annual estimated tax rate of 28% and 30% respectively to calculate the provision for income taxes. The effective tax rate was 28% and 26% for the six months ended June 30, 2016 and 2017, respectively. The difference between the annual estimated tax rate and the effective tax rate for six months ended June 30, 2017 is due to the tax impact of discrete items such as share-based compensation in the United States.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes by Criteo S.A., Criteo Corp. and Criteo Brazil. The current tax liabilities refers mainly to the net corporate tax payables of Criteo Italy, Criteo K.K. and Criteo Deutschland.

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.

Weighted average number of shares outstanding	63,246,785		65,027,985		62,928,221		64,611,237
Basic earnings per share	$	0.19	$	0.09	$	0.47	$	0.28

19

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 June 30, 2016 and 2017. 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 non-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).

Note 14. Commitments and contingencies

Commitments

Leases

We are party to various contractual commitments mainly related to our offices as well as hosting services. There have been no significant changes in future payment obligations for these contractual commitments from what was disclosed in Note 23 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. Certain of these arrangements have free rent periods or escalating rent payment provisions, and we recognize rent expense under such arrangements on a straight-line basis.

Rent expenses relating to our offices totaled $7.6 million and $8.6 million for the three-month period ended June 30, 2016 and 2017, respectively and $15.0 million and $17.4 million for the six-month period ended June 30, 2016 and 2017, respectively.

Hosting costs totaled $10.5 million and $17.1 million for the three-month period ended June 30, 2016 and 2017, respectively and $19.8 million and $31.0 million for the six-month period ended June 30, 2016 and 2017, respectively.

Revolving Credit Facilities, Credit Line Facilities and Bank Overdrafts

As mentioned in Note 9, we are party to two RCFs including one with HSBC for which we can draw up to RMB 50.0 million ($7.4 million) and one with a syndicate of banks which allow us to draw up to €350.0 million ($399.4 million), further to the amendment signed in March 2017 increasing the facility amount from €250.0 million to €350.0 million and extending the term of the contract from 2020 to 2022. As of June 30, 2017, RMB 30.0 million ($4.4 million), and €0.0 million ($0.0 million), respectively, were drawn on the RCFs.

Both of these credit facilities are unsecured and contain customary events of default but do not contain any affirmative, financial or negative covenants, with the exception of the €350.0 million ($399.4 million) RCF which contains covenants, including compliance with a total net debt to adjusted EBITDA ratio and restrictions on incurring additional indebtedness. As of June 30, 2017, we were in compliance with the required leverage ratio.

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, 2016, filed with the Securities and Exchange Commission, or "SEC", on March 1, 2017.

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, 2016.

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 2017.

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.

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.

24

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.

Our use of Revenue ex-TAC has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; (b) other companies may report Revenue ex-TAC or similarly titled measures but calculate them differently, which reduces their usefulness as a comparative measure.

⁽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. We have included Adjusted Net Income in this Form 10-Q because it is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of equity awards compensation expense, amortization of acquisition-related intangible assets, restructuring costs, acquisition-related costs and deferred price consideration, and the tax impact of the foregoing adjustments in calculating Adjusted Net Income can provide a useful measure for period-to-period comparisons of our core business.

Our use of Adjusted Net Income has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) Adjusted Net Income does not reflect the potentially dilutive impact of equity-based compensation or the impact of certain acquisition related costs; and (b) other companies, including companies in our industry, may calculate Adjusted Net Income or similarly titled measures differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Adjusted Net Income alongside our other U.S. GAAP financial results, including net income.

⁽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 2016 average exchange rates for the relevant period to 2017 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 June 30, 2017increased to $542.0 million, growing 33.1% (or 35.3% on a constant currency basis), compared to the three months ended June 30, 2016. Revenue from new clients contributed 55.8% to the year-over-year revenue growth, while revenue from existing clients contributed 44.2% to the year-over-year revenue growth. This increase in revenue was primarily driven by continued innovation across devices, our broader and improved access to publisher inventory, and the addition of close to 4,500 net new clients across regions, sizes and products. Technology improvements and broader inventory reach helped generate more revenue from existing clients at constant currency. Our ability to convert and maintain a large portion of our clients to uncapped budgets was a key driver of the increase in revenue per existing client across large and midmarket clients.

The year-over-year increase was the result of our growth across all regions. Revenue in the Americas region increased46.6% (or 45.8% on a constant currency basis) to $229.4 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016, and the region remained the largest contributor to our global growth. We had good success in client additions in retail and travel as well as in newer verticals like finance and media. Revenue in EMEA increased24.6% (or 29.5% on a constant currency basis) to $191.7 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016. Our largest Western European markets again experienced double-digit growth. Business with existing Tier 1 and midmarket clients was particularly strong, especially with the largest of our clients in the region. The addition of Tier 1 and midmarket clients remained a significant driver across all markets. Revenue in the Asia-Pacific region increased25.0% (or 27.5% on a constant currency basis) to $120.9 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016. Japan grew strongly again across Tier 1 and midmarket, in particular with respect to top clients. Growth in South East Asia remained strong, largely driven by a buoyant in-app business across all markets.

    Additionally, our $542.0 million of revenue for the three months ended June 30, 2017 was negatively impacted by $8.9 million as a result of changes in foreign currency against the U.S. dollar compared to the three months ended June 30, 2016.

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

Our revenue depends on our ability to access and leverage user data. Notably, Apple recently announced the launch of its Intelligent Tracking Prevention feature, or ITP, as part of a new version of the Safari browser expected to be released in September 2017. This feature will make it more difficult for third-party providers like us to access data on Safari users. While we have a proven track-record of adapting quickly and effectively to business and technological changes, this change may affect our ability to access and leverage user data, which could adversely affect our revenue.

We signed up new Tier 1 and midmarket clients across the region and saw our new product initiatives, like CRM onboarding and store-to-web retargeting campaigns, drive higher-level discussions with clients. Revenue in EMEA increased21.5% (or 26.9% on a

32

constant currency basis) to $380.8 million for the six months ended June 30, 2017 compared to the six months ended June 30, 2016. Large Western European markets continued to post solid double-digit growth, with strong performance across Tier 1 and midmarket accounts.

Japan continued to post solid growth, in particular with our largest clients, and growth in South-East Asia remained strong across the various markets.

Additionally, our $1,058.7 million of revenue for the six months ended June 30, 2017 was negatively impacted by $12.6 million as a result of changes in foreign currency against the U.S. dollar compared to the six months ended June 30, 2016.

% of revenue	(64.2		)%	(65.5		)%
Gross profit %	35.8		%	34.5		%

Cost of revenue for the three months ended June 30, 2017increased$93.7 million, or 35.9%, compared to the three months ended June 30, 2016. This increase was primarily the result of an increase of $81.2 million, or 33.7% (or 35.8% on a constant currency basis), in traffic acquisition costs and a $12.5 million, or 61.8% (or 64.8% on a constant currency basis), increase in other cost of revenue.

The increase in traffic acquisition costs related primarily to an increase of 41% in the number of impressions we purchased, driven by both publishers with whom we have direct relationships, including the Criteo Publisher Marketplace, and the main real-time bidding exchanges, both global and local. Over the period, the average cost per thousand impressions (or "CPM") decreased by 5.4% (or 3.8% on a constant currency basis).

The year-over year growth in traffic acquisition costs was the result of our strong growth across all geographies. Traffic acquisition costs in the Americas region increased 50.5% (or 50.0% on a constant currency basis) to $145.3 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016, as our purchases of impressions from the main real-time bidding exchanges increased and we maintained strong direct relationships with large premium publishers. Traffic acquisition costs in EMEA increased 22.8% (or 28.0% on a constant currency basis) to $106.6 million for the three months ended June 30, 2017 compared to the three months ended June 30, 2016, as our purchases of impressions from both large publishers with whom we have direct relationships and the main real-time bidding exchanges increased across several markets in the region.

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

The $0.1 million financial expense for the three months ended June 30, 2016 was mainly the result of a neutral impact of foreign exchange reevaluations and related hedging together with the recognition of the fees related to the revolving credit facility entered into in September 2015 (as amended in March 2017).

Net income for the six months ended June 30, 2017 decreased$9.8 million, or (30.9)%, compared to the six months ended June 30, 2016. This decrease was the result of the factors discussed above, in particular, a $11.3 million decrease in income from operations and a $3.0 million increase in financial expense, partially offset by a $4.5 million decrease in provision for income taxes compared to the three months ended June 30, 2016.

⁽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 2016 average exchange rates for the relevant period to 2017 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:

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operating activities. We also benefited to a much lesser extent from the proceeds of the exercise of share options and warrants and expect to continue to do so in the future, as such securities are exercised by holders. 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 9 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 and money market funds that are currently providing only a minimal return. Our cash and cash equivalents at June 30, 2017 were held for working capital and general corporate purposes, which could include acquisitions, and amounted to $308.2 million as of June 30, 2017. The $37.9 million increase in cash and cash equivalents compared with December 31, 2016 primarily resulted from $104.7 million in cash from operating activities. This was offset by $52.9 million used for investing activities and $53.0 million of cash used for financing activities over the period. The cash used for investing activities is mainly related to $55.3 million in capital expenditures. The cash used for financing activities is primarily related to the payment of the $75 million drawn on the RCF for the acquisition of HookLogic offset by $24.5 million from the exercise of stock options. In addition, the increase in cash includes a $39.1 million positive 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 and money market funds that are currently providing only a minimal return.

Operating and Capital Expenditure Requirements

For the six months ended June 30, 2016 and 2017, our capital expenditures were $34.5 million and $55.3 million, respectively, primarily related to the acquisition of data center and server equipment as well as furnishing and leasehold improvements of new offices. 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.

41

Historical Cash Flows

The following table sets forth our cash flows for the six month period ended June 30, 2016 and 2017:

	Six Months Ended
	June 30, 2016			June 30, 2017
	(in thousands)
Cash from operating activities	$	38,181		$	104,729
Cash used in investing activities	$	(38,993	)	$	(52,935	)
Cash used for financing activities	$	13,022		$	(53,049	)

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 operating items such as depreciation, amortization and share-based compensation, deferred tax assets and income taxes.

For the six months ended June 30, 2017, net cash provided by operating activities was $104.7 million and consisted of net income of $22.0 million, $84.4 million in adjustments for certain operating items and changes in working capital of $25.8 million partially offset by $27.5 million of income taxes paid during the first six months of 2017. Adjustments for certain operating items primarily consisted of depreciation and amortization expense of $46.7 million, equity awards compensation expense of $29.9 million and $20.3 million of accrued income taxes, partially offset by $12.4 million of changes in deferred tax assets. The $25.8 million increase in cash from changes in working capital primarily consisted of a $36.2 million decrease in trade receivables, a $13.3 million increase in other current liabilities such as payroll and payroll related expenses and VAT payables, and a $2.6 million decrease in other current assets including prepaid expenses and value-added tax ("VAT") receivables. This was partially offset by a $26.3 million decrease in trade payables.

Investing Activities

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

For the six months ended June 30, 2017, net cash used in investing activities was $52.9 million and consisted of $55.3 million for purchases of property and equipment partially offset by $1.3 million for various lease deposits and $1.1 million in payments for acquired business due to a change in the purchase price for HookLogic.

Financing Activities

For the six months ended June 30, 2017, net cash used for financing activities was $53.0 million resulting from $79.2 million in repayment of borrowings (mainly due to the repayment of the $75.0 million drawn on the RCF) partially offset by $24.5 million of share option exercises, $1.5 million of additional borrowings on the Chinese RCF, and $0.3 million of other financial liabilities.

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 six months of 2017.

For a description of our foreign exchange risk, please see "Item 7. Management's Discussion and Analysis of Financial Condition ans Results of Operations - B. Liquidity and Capital Resources" in our Annual Report on Form 10-K for the year ended December 31, 2016.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Based on their evaluation as of June 30, 2017, 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.

44

PART II

Item 1.    Legal Proceedings.

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

Item 1A. Risk Factors.

You should carefully consider the risks described under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016. 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, 2016.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Criteo S.A. is a global technology company specialized in digital performance marketing. We strive to deliver post-click sales to our advertiser clients at scale and according to the client's targeted return on investment. 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". The Company uses its proprietary predictive software algorithms coupled with its deep insights into expressed consumer intent and purchasing habits to price and deliver highly relevant and personalized performance advertisements to consumers in real time.

Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements included herein 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, 2016, filed with the SEC on March 1, 2017. 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) the recognition of revenue and particularly the determination as to whether revenue should be reported on a gross or a net basis; (2) the evaluation of our trade receivables and the recognition of a valuation allowance for doubtful accounts; (3) the recognition and measurement of goodwill and intangible assets and particularly costs capitalized in relation to our customized internal-use software; (4) the measurement of share-based compensation and (5) the tax provision determination and particularly the estimate of our annual effective tax rate based on applicable tax rates.

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, 2016 that have had a material impact on our unaudited condensed consolidated financial statements and related notes.

Accounting Pronouncements adopted in 2017

From January 1, 2017, we adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting issued by the Financial Accounting Standards Board (FASB), which among other items, simplifies certain aspects of the accounting for share-based payment transactions to employees. The new standard particularly requires excess tax benefits and tax deficiencies to be recorded in the statements of income as a component of the provision for income taxes when stock awards vest or are settled. The effective date is January 1, 2017. Upon adoption, a cumulative effect of $10.0 million of this change has been recognized through retained earnings. The adoption of the standard also resulted in a current year tax expense of $1.4 million which previously would have been recognized in the current period in additional paid-in capital.

Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) ("ASU 2017-01") the purpose of which is to change the definition of a business to assist entities in evaluating when a set of transferred assets and activities is a business. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of ASU 2017-01 is not expected to have a material impact on our financial position or results of operations.

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 March 2017, FASB issued ASU 2017-07 Compensation-Retirements Benefits (Topic 715). ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendments in ASU 2017-07 improve the consistency, transparency, and usefulness of financial information to users that have communicated that the service cost component generally is analyzed differently from the other components of net benefit cost. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-07 is not expected to have a material impact on our financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09 Compensation - Stock Compensation (Topic 718). ASU 2017-09 was issued to provide clarity and reduce diversity in practice and complexity when applying the guidance in Topic 718 to a change in terms or conditions of a share based payment award. The amendments are effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted and should be applied prospectively to an award modified on or after the adoption date. To date, Criteo has not yet had any modifications of its share-based awards. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-09 is not expected to have a material impact on our financial position or results of operations.

Fair Value Disclosures [Abstract]

Financial Instruments

Credit Risk

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, 2016		June 30, 2017
Cash and cash equivalents	$	270,317	$	308,185
Trade receivables, net of allowance	397,244		370,052
Other taxes	52,942		46,514
Other current assets	19,340		28,270
Non-current financial assets	17,029		18,824
Total	$	756,872	$	771,845

As of December 31, 2016 and June 30, 2017, no customer accounted for 10% or more of trade receivables.

We perform ongoing credit evaluations of our customers and do not require collateral. We maintain an allowance for estimated credit losses. During the twelve-month period ended December 31, 2016 and the six-month period ended June 30, 2017, our allowance for doubtful accounts increased by $5.4 million and $3.1 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.

Fair Value Measurements     

We measure the fair value of our cash equivalents, which include money market funds and interest bearing deposits, as level 1 and level 2 measurements because they are valued using quoted market prices and observable market data, respectively.

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.

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.

For each period presented, the aging of trade receivables and allowances for potential losses is as follows:

	December 31, 2016									June 30, 2017

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.

Cash and Cash Equivalents

Cash and cash equivalents include investments in money market funds and 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. Money market funds are considered level 1 financial instruments as they are valued using quoted market prices. Interest-bearing bank deposits are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.

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"), free shares/restricted share units ("RSUs") and non-employee warrants (Bons de Souscription d'Actions or "BSAs").

During the six months ended June 30, 2017, there were three grants of RSUs and one grant of OSAs under the Employee Share Option Plan 9 and one grant of BSAs under the Plan F, 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, 2016.

• On March 1, 2017, 231,460 RSUs were granted to Criteo employees subject to continued employment and 10,825 BSAs were granted to a board member subject to continued engagement on the board of directors.

• On April 27, 2017, 139,386 RSUs were granted to Criteo employees subject to continued employment.

• On June 27, 2017, 135,500 RSUs were granted to senior management subject to achievement of internal performance objectives and continued employment. Based on the assumptions known as of June 30, 2016, we determined share-based compensation expense by applying the probability of performance objectives completion. In addition, on June 27, 2017, 896,586 RSUs and 355,010 OSAs 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, 2016, filed with the SEC on March 1, 2017.

Financial Income and Expenses

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

	Three Months Ended
	June 30, 2016			June 30, 2017
	(in thousands)
Financial income from cash equivalents	$	482		$	202
Interest and fees	(612		)	(656		)

Foreign exchange gain (loss)	41			(1,625		)
Other financial expense	(5		)	(15		)
Total financial income (expense)	$	(94	)	$	(2,094	)

The $2.1 million financial expense for the three months ended June 30, 2017 was driven by the hedging cost 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 in November 2016 and the non-utilization fees incurred as part of our available RCF financing. The $0.1 million financial expense for the three months ended June 30, 2016 was mainly the result of a neutral impact of foreign exchange reevaluations and related hedging together with the recognition of the fees related to the revolving credit facility entered into in September 2015 (as amended in March 2017).

Total financial income (expense)	$	(1,412	)	$	(4,427	)

The $4.4 million financial expense for the six months ended June 30, 2017 was driven by the interest accrued as a result of the $75 million drawn on the revolving credit facility entered into in September 2015 (as amended in March 2017) and the hedging cost related to an intra-group position between Criteo S.A. and its U.S. subsidiary, both in the context of the funding of the HookLogic acquisition in November 2016, as well as the non-utilization fees incurred as part of our available RCF financing. The $1.4 million financial expense for the six months ended June 30, 2016 was mainly a result of the recognition of the negative impact of foreign exchange reevaluations and related hedging recorded during the first quarter, together with the fees related to the revolving credit facility entered into in September 2015 (as amended in March 2017).

Income Tax Disclosure [Abstract]

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 changes, 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:

	Six Months Ended
	June 30, 2016			June 30, 2017
	(in thousands)
Current income tax	$	(16,818	)	$	(20,271	)

International	(8,646		)	(12,982		)
Net change in deferred taxes	4,424			12,405
France	4,216			(944		)
International	208			13,349
Provision for income taxes	$	(12,394	)	$	(7,866	)

For the six months ended June 30, 2016 and 2017, we utilized an annual estimated tax rate of 28% and 30% respectively to calculate the provision for income taxes. The effective tax rate was 28% and 26% for the six months ended June 30, 2016 and 2017, respectively. The difference between the annual estimated tax rate and the effective tax rate for six months ended June 30, 2017 is due to the tax impact of discrete items such as share-based compensation in the United States.

Current tax assets and liabilities

The total amount of current tax assets consists mainly of prepayments of income taxes by Criteo S.A., Criteo Corp. and Criteo Brazil. The current tax liabilities refers mainly to the net corporate tax payables of Criteo Italy, Criteo K.K. and Criteo Deutschland.

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 June 30, 2016 and 2017. 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 non-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).

Leases

We are party to various contractual commitments mainly related to our offices as well as hosting services. There have been no significant changes in future payment obligations for these contractual commitments from what was disclosed in Note 23 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. Certain of these arrangements have free rent periods or escalating rent payment provisions, and we recognize rent expense under such arrangements on a straight-line basis.

Rent expenses relating to our offices totaled $7.6 million and $8.6 million for the three-month period ended June 30, 2016 and 2017, respectively and $15.0 million and $17.4 million for the six-month period ended June 30, 2016 and 2017, respectively.

Hosting costs totaled $10.5 million and $17.1 million for the three-month period ended June 30, 2016 and 2017, respectively and $19.8 million and $31.0 million for the six-month period ended June 30, 2016 and 2017, respectively.

Revolving Credit Facilities, Credit Line Facilities and Bank Overdrafts

As mentioned in Note 9, we are party to two RCFs including one with HSBC for which we can draw up to RMB 50.0 million ($7.4 million) and one with a syndicate of banks which allow us to draw up to €350.0 million ($399.4 million), further to the amendment signed in March 2017 increasing the facility amount from €250.0 million to €350.0 million and extending the term of the contract from 2020 to 2022. As of June 30, 2017, RMB 30.0 million ($4.4 million), and €0.0 million ($0.0 million), respectively, were drawn on the RCFs.

Both of these credit facilities are unsecured and contain customary events of default but do not contain any affirmative, financial or negative covenants, with the exception of the €350.0 million ($399.4 million) RCF which contains covenants, including compliance with a total net debt to adjusted EBITDA ratio and restrictions on incurring additional indebtedness. As of June 30, 2017, we were in compliance with the required leverage ratio.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited condensed consolidated financial statements included herein 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, 2016, filed with the SEC on March 1, 2017. 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.

Use of Estimates

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) the recognition of revenue and particularly the determination as to whether revenue should be reported on a gross or a net basis; (2) the evaluation of our trade receivables and the recognition of a valuation allowance for doubtful accounts; (3) the recognition and measurement of goodwill and intangible assets and particularly costs capitalized in relation to our customized internal-use software; (4) the measurement of share-based compensation and (5) the tax provision determination and particularly the estimate of our annual effective tax rate based on applicable tax rates.

Recently Issued Accounting Standards

Accounting Pronouncements adopted in 2017

From January 1, 2017, we adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting issued by the Financial Accounting Standards Board (FASB), which among other items, simplifies certain aspects of the accounting for share-based payment transactions to employees. The new standard particularly requires excess tax benefits and tax deficiencies to be recorded in the statements of income as a component of the provision for income taxes when stock awards vest or are settled. The effective date is January 1, 2017. Upon adoption, a cumulative effect of $10.0 million of this change has been recognized through retained earnings. The adoption of the standard also resulted in a current year tax expense of $1.4 million which previously would have been recognized in the current period in additional paid-in capital.

Accounting Pronouncements not yet adopted

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) ("ASU 2017-01") the purpose of which is to change the definition of a business to assist entities in evaluating when a set of transferred assets and activities is a business. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of ASU 2017-01 is not expected to have a material impact on our financial position or results of operations.

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 March 2017, FASB issued ASU 2017-07 Compensation-Retirements Benefits (Topic 715). ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendments in ASU 2017-07 improve the consistency, transparency, and usefulness of financial information to users that have communicated that the service cost component generally is analyzed differently from the other components of net benefit cost. This update will be effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-07 is not expected to have a material impact on our financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09 Compensation - Stock Compensation (Topic 718). ASU 2017-09 was issued to provide clarity and reduce diversity in practice and complexity when applying the guidance in Topic 718 to a change in terms or conditions of a share based payment award. The amendments are effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted and should be applied prospectively to an award modified on or after the adoption date. To date, Criteo has not yet had any modifications of its share-based awards. We intend to adopt the standard on the effective date of January 1, 2018. The adoption of ASU 2017-09 is not expected to have a material impact on our financial position or results of operations.
