The statements of financial position of consolidated entities having a functional currency different from the U.S. dollar are translated into U.S. dollars at the closing exchange rate (spot exchange rate at the statement of financial position date) and the statements of income, statements of comprehensive income and statements of cash flow of such consolidated entities are translated at the average period to date exchange rate. The resulting translation adjustments are included in equity under the caption “Accumulated other comprehensive income (loss)” in the Consolidated Statements of Changes in Shareholders' Equity. Conversion of Foreign Currency Transactions Foreign currency transactions are converted to U.S. dollars at the rate of exchange applicable on the transaction date. At period-end, foreign currency monetary assets and liabilities are converted at the rate of exchange prevailing on that date. The resulting exchange gains or losses are recorded in the Consolidated Statements of Income in “Other financial income (expense)” with the exception of exchange differences arising from monetary items that form part of the reporting entity’s net investment in a foreign operation which are recognized in other comprehensive income (loss); they will be recognized in profit or loss on disposal of the net investment. Use of Estimates The preparation of our Consolidated Financial Statements requires the use of estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenue and expenses during the period. We base our estimates and assumptions on historical experience and other factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (1) gross vs net assessment in revenue recognition (2) allowances for credit losses, (3) income taxes, (4) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (5) assumptions used in the valuation of goodwill, intangible assets and leases, (6) assumptions used in the valuation model to determine the fair value of share-based compensation plan, (7) assumptions surrounding the recognition and valuation of contingent liabilities and losses. Business combinations We include the results of operations of the businesses that we acquire as of the acquisition date. We allocate the purchase price of our acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. Intangible Assets Acquired intangible assets are accounted for at acquisition cost, less accumulated amortization. Acquired intangible assets are composed of technology and customer relationships amortized on a straight-line basis over their estimated useful lives comprised between three Intangible assets also include costs to develop software to be used solely to meet internal needs and cloud based applications used to deliver our services. We capitalize development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended. Amortization of these costs begins when assets are placed in service and is calculated on a straight-line basis over the assets’ useful lives, generally estimated at three years. Cloud computing arrangements (“CCAs”), such as software as a service and other hosting arrangements, are evaluated for capitalized implementation costs in a similar manner as capitalized software development costs. If a CCA includes a software license, the software license element of the arrangement is accounted for in a manner consistent with the acquisition of other software licenses. If a CCA does not include a software license, the service element of the arrangement is accounted for as a service contract. The Company capitalizes certain implementation costs for its CCAs that are service contracts, which are included in other current assets. The Company amortizes capitalized implementation costs in a CCA over the life of the service contract. Property, Plant and Equipment Property, plant and equipment are accounted for at acquisition cost less cumulative depreciation and any impairment loss. Depreciation is calculated on a straight-line basis over the assets’ estimated useful lives as follows: Servers........................................................................................................... 5 years over the life of the warranty Furniture and IT equipments............................................................................................................... 3 to 5 years Leasehold improvements are depreciated over their useful life or over the lease term, whichever is shorter. Impairment of Assets Goodwill and Intangible Assets Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives. The Company evaluates the estimated remaining useful lives of purchased intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as three single reporting units and has selected December 31 as the date to perform its annual impairment test. Goodwill has been allocated to these three segments using a relative fair value allocation approach. In the impairment assessment of its goodwill, the Company performs an impairment test, which involves assumptions regarding estimated future cash flows to be derived from the Company. The estimated future cash flows are used to derive the fair value of the reporting unit, which is then compared to its net book value, including goodwill . If these estimates or their related assumptions change in the future, the Company may be required to record impairment on these assets. If the net book value exceeds its implied fair value, then the Company would be required to recognize an impairment loss in the Consolidated Statement of Income. Acquired intangible assets are accounted for at acquisition cost less cumulative amortization and any impairment loss. Acquired intangible assets are amortized over their estimated useful lives of three Property, Plant and Equipment and Impairment of Long-lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful life is no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with an asset are less than the carrying amount of the asset, an impairment loss is recorded to write the asset down to its estimated fair value. Fair value is estimated based on discounted future cash flows. Leases We lease space under non-cancellable operating leases for our offices and data centers. Our office leases typically include rent free periods and rent escalation periods, and may also include leasehold improvement incentives. Leases for data centers may also include rent free periods and rent escalation periods. 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. Our leases typically contain options to renew, and/or early terminate the lease. Options have been included in the lease term if management has determined it is reasonably certain that they will be exercised, at lease commencement. 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 include changes in indexation and are expensed in the period incurred. We chose to use certain practical expedients upon adaption of ASC 842 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. Financial Assets and Liabilities, Excluding Derivative Financial Instruments Financial assets, excluding cash and cash equivalents, consist exclusively of loans and receivables. Loans and receivables are non-derivative financial assets with a payment, which is fixed or can be determined, not listed on an active market. They are included in current assets, except those that mature more than twelve months after the reporting date. Loans are measured at amortized cost using the effective interest method. The recoverable amount of loans and advances is estimated whenever there is an indication that the asset may be impaired and at least on each reporting date. If the recoverable amount is lower than the carrying amount, an impairment loss is recognized in the Consolidated Statements of Income. Financial liabilities are initially recorded at their fair value at the transaction date. Subsequently they are measured at amortized cost using the effective interest method. The Company carries the accounts receivable at original invoiced amount less an allowance for any potential uncollectible amounts. Receivables are presented on a gross basis and are not netted against the payments we are required to make to advertising inventory publishers. Management makes estimates of expected credit trends for the allowance for credit losses based on, among other factors, a past history of collections, current credit conditions, the aging of the receivables, past history of write downs, credit quality of our customers, current economic conditions, and reasonable and supportable forecasts of future economic conditions. A receivable is considered past due if we have not received payments based on agreed-upon terms. A higher default rate than estimated or a deterioration in our clients’ creditworthiness could have an adverse impact on our future results. Allowances for credit losses on trade receivables are recorded in “sales and operations expenses” in our Consolidated Statements of Income. We generally do not require any security or collateral to support our receivables. Derivative financial instruments We buy and sell derivative financial instruments in order to manage and reduce our exposure to the risk of exchange rate fluctuations. We deal only with major financial institutions. Financial instruments may only be classified as hedges when we can demonstrate and document the effectiveness of the hedging relationship at inception and throughout the life of the hedge. Generally, our derivatives are not designated as hedging instruments and mainly consist of forward buying 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, as well as the related costs in the financial income (expense), net, along with the foreign currency gains and losses on monetary assets and liabilities. We report the cash impact of the settlement of hedging derivatives in cash from (used for) financing activities in the consolidated statements of cash flows. This results in the cash flows from derivative instruments to be classified in the same category as the underlying cash flows. Derivatives are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data. Fair value measurements Financial instruments are presented in three categories based on a hierarchical method used to determine their fair value : (i) level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities; (ii) level 2: fair value calculated using valuation techniques based on observable market data such as prices of similar assets and liabilities or parameters quoted in an active market; (iii) level 3: fair value calculated using valuation techniques based wholly or partially on unobservable inputs such as prices in an active market or a valuation based on multiples for unlisted companies. Cash, Cash Equivalents and Marketable Securities Cash includes cash on deposit with banks and highly liquid investments such as demand deposits with banks. Cash equivalents include short-term, highly liquid investments, with a remaining maturity at the date of purchase of three months or less for which the risk of changes in value is considered to be insignificant. Highly liquid term deposits therefore meet the definition of cash equivalents. We hold investments in marketable securities, consisting mainly of term deposits with banks, not meeting the cash equivalents definition. We classify marketable securities as either available-for-sale or held-to-maturity investments, depending on whether we have the positive intent and ability to hold the term deposits to maturity. Our available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) in stockholders' equity. Our held-to-maturity investments are carried at amortized cost, and are subject to impairment assessments. Interest income generated from held-to-maturity investments is recorded as financial income. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company’s cash and cash equivalents are held and foreign exchange contracts are transacted with major financial institutions that the Company's management has assessed to be of high credit quality. The Company has not experienced any losses in such accounts. The Company mitigates its credit risk with respect to accounts receivable by performing credit evaluations and monitoring agencies' and advertisers' accounts receivable balances. As of December 31, 2022 and 2021 no customer accounted for 10% or more of accounts receivable. During the years ended December 31, 2022, 2021 and 2020, no single customer represented 10% or more of revenue. Employee Benefits Depending on the laws and practices of the countries in which we operate, employees may be entitled to compensation when they retire or to a pension following their retirement. For state-managed plans and other defined contribution plans, we recognize them as expenses when they become payable, our commitment being limited to our contributions. The liability with respect to defined benefit plans is estimated using the following main assumptions: • discount rate; • future salary increases; • employee turnover; and • mortality tables. Service costs are recognized in profit or loss and are allocated by function. Actuarial gains and losses are recognized in other comprehensive income and subsequently amortized into the income statement over a specified period, which is generally the expected average remaining service period of the employees participating in the plan. Actuarial gains and losses arise as a result of changes in actuarial assumptions or experience adjustments (differences between the previous actuarial assumptions and what has actually occurred). Contingencies An estimated loss from a loss contingency is recognized if the following two conditions are met: • information available before the financial statements are issued indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements; • the amount of loss can be reasonably estimated. With respect to litigation, claims and non income tax risks, that may result in a provision to be recognized, we exercise significant judgment in measuring and recognizing provisions or determining exposure to contingent liabilities that are related to pending litigation, other outstanding claims and tax audits. These judgment and estimates are subject to change as new information becomes available. Revenue Recognition We sell personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. We have multiple pricing models which include percentage of spend models in addition to cost-per-click, cost-per-install and cost-per-impression pricing models. Cost-per-click, cost-per-install and cost-per-impression pricing models We recognize revenues when we transfer control of promised services directly to 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, 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, as we consider the delivery of clicks or installs our performance obligation. 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 as we consider the display of advertisements our performance obligation. Percentage of spend models Criteo's Platform enables the buying and selling of retail media with an end-to-end, self-service platform geared toward our brand, agency and retailer customers and is priced using a percentage of spend model. We generate revenues when we provide a platform for the purchase and sale of retail media digital advertising inventory. The platform connects sellers and buyers of retail media inventory, in an online marketplace. Retailers provide advertising inventory to the platform and brands and agencies bid on the retailers digital advertising inventory. Winning bids can create advertising, or paid impressions, which retailers display to their website visitors. The total volume of spending between buyers and sellers on the Company's platform is referred to as working media spend. We charge both the brands and agencies and retailers a contractual fee, based on a percentage of working media spend, for the use of our platform. We recognize revenue when an ad is displayed or clicked on. Criteo's Iponweb solutions offer an online trading platform through which supply partners can submit bid requests for media that they wish to sell, and demand partners can submit bids for media that they wish to buy through the operations of a dynamic, real-time exchange whereby media is sold to demand partners whose bids are selected by supply partners. We generate revenues by charging demand or supply a percentage of total media spend traded through our solutions. We recognize revenue when an ad is displayed or clicked on. Agent vs Principal When a third-party is involved in the delivery of our services to the client, through the supply of digital advertising inventory, we assess whether we act as principal or agent in the arrangement. The assessment is based on the degree we control the specified services at any time before they are transferred to the customer. The determination of whether we are acting as principal or agent requires judgment. We act as principal in our Criteo Marketing Solutions arrangements because (i) we control the advertising inventory before it is transferred to our clients; (ii) we bear sole responsibility in fulfillment of the advertising promise and bear inventory risks and (iii) we have full discretion in establishing prices. Therefore, based on these and other factors, we have determined that we act as principal for our Criteo Marketing Solutions engagements and accordingly report the revenue earned and related costs incurred on a gross basis. We act either as principal or as agent in our Criteo Retail Media segment. For the arrangements related to transactions using our legacy Retail Media solutions, we consider that we act as principal, as we exercise significant control over the client’s advertising campaign. For arrangements related to transactions using our Platform, a self-service solution providing transparency, measurement and control to our brand, agency and retailer customers, we act as agent, because we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a platform fee based on a percentage of the digital advertising inventory purchased through the use of the platform. Therefore, we report the revenue earned and related costs incurred by the Platform solution on a net basis. We act as agent in Iponweb provided solutions as we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a fee based on a percentage of the digital advertising inventory traded through our solutions. Therefore, we report the revenue earned and related costs incurred by the Iponweb solutions on a net basis. 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. Cost of Revenue Our cost of revenue primarily includes traffic acquisition costs and other cost of revenue. Traffic Acquisition Costs . Traffic acquisition costs consist primarily of purchases of impressions from publishers on a CPM basis. We purchase impressions directly from publishers or third-party intermediaries, such as advertisement exchanges. We recognize cost of revenue on a publisher by publisher basis as incurred. Costs owed to publishers but not yet paid are recorded in our Consolidated Statements of Financial Position as trade payables. For legacy solutions within Criteo Retail Media, we pay for the inventory of our retailer partners on a revenue sharing basis, effectively paying the retailers a portion of the click-based revenue generated by user clicks on the sponsored products advertisements or impressions on the commerce display advertisements displaying the products of our consumer brand clients. For Retail Media Platform solutions, revenue is recognized on a net basis, and there are no associated Traffic Acquisition Costs. For solutions within Iponweb, revenue is recognized on a net basis, and there are no associated Traffic Acquisition Costs. Other Cost of Revenue . Other cost of revenue includes expenses related to third-party hosting fees, depreciation of data center equipment, data purchased from third parties and digital taxes. The Company does not build or operate its own data centers and none of its Research and Development employments are dedicated to revenue generating activities. As a result, we do not include the costs of such personnel in other cost of revenue. Share-Based Compensation Shares, employee share options and employee and non-employee warrants are primarily awarded to our employees or directors. These awards are measured at their fair value on the date of grant. The fair value is calculated with the most relevant formula regarding the settlement and the conditions of each plan. The fair value is recorded in personnel expenses (allocated by function in the Consolidated Statements of Income) on a straight-line basis over each milestone composing the vesting period with a corresponding increase in shareholders’ equity. At each closing date, we re-examine the number of options likely to become exercisable. If applicable, the impact of the review of the estimate is recognized in the Consolidated Statements of Income with a corresponding adjustment in equity. Income Taxes Income taxes are accounted for under the asset and liability method of accounting. Deferred taxes are recorded on all temporary differences between the financial reporting and tax bases of assets and liabilities, and on tax losses, using the liability method. Differences are defined as temporary when they are expected to reverse within a foreseeable future. We may only recognize deferred tax assets on net operating losses if, based on the projected taxable incomes within the next three years, we determine that it is probable that future taxable profit will be available against which the unused tax losses and tax credits can be utilized. As a result, the measurement of deferred income tax assets is reduced, if necessary, by a valuation allowance for any tax benefits which are not expected to be realized. If future taxable profits are considerably different from those forecasted that support recording deferred tax assets, we will have to revise downwards or upwards the amount of deferred tax assets, which would have a significant impact on our financial results. Tax assets and liabilities are not discounted. Amounts recognized in the Consolidated Financial Statements are calculated at the level of each tax entity included in the consolidation scope. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The French Research Tax Credit, Crédit d’Impôt Recherche (“CIR”), is a French tax incentive to stimulate research and development (“R&D”). Generally, the CIR offsets the income tax to be paid and the remaining portion (if any) can be refunded at the end of a three-fiscal year period. The CIR is calculated based on the claimed volume of eligible R&D expenditures by us. As a result, the CIR is presented as a deduction to “research and development expenses” in the Consolidated Statements of Income, as the CIR is not within the scope of ASC 740. We have exclusively claimed R&D performed in France for purposes of the CIR. As of December 31, 2022, we have offset $14.7 million of CIR tax credits against “research and development expenses” in our Consolidated Statements of Income. The U.S. Research Tax Credit is a U.S. tax credit to incentivize research and development activities in the U.S. Qualifying R&D expenses generating a tax credit which may be used to offset future taxable income once all net operating losses and foreign tax credits have been used. It is not refundable and as such, considered in the scope of ASC 740 as a component of income tax expense. We have exclusively claimed R&

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations On August 1, 2022, the Company, Iponweb Holding Limited, Exezars Limited (a subsidiary of Iponweb Holding Limited and collectively with Iponweb Holding Limited, the “Sellers”), Mr. Ljubisa Bogunovic, in his capacity as trustee of the “IW General Management Trust” and Mr. Boris Mouzykantskii, founder and Chief Executive Officer of Iponweb Holding Limited (the “Founder”) entered into an amended and restated Framework Purchase Agreement (the “FPA”), amending and restating the previously disclosed framework purchase agreement, dated December 22, 2021, which provided for the acquisition of the business of Iponweb Holding Limited (the "Iponweb business"), a market-leading AdTech company with world-class media trading capabilities, by the Company (the “Iponweb Acquisition”). This business combination is composed of an asset purchase of Iponweb intellectual property and other intangible rights and a share purchase of 100% of the share capital and voting rights of nine Iponweb operational legal entities. Purchase price. The purchase price, as per ASC 805, was $290.2 million (subject to approval and finalization of post-close purchase price adjustments) for the Iponweb business, out of which $61.2 million represents the fair value of the contingent consideration. This contingent consideration is payable in cash to the Sellers in an amount up to $100 million, conditioned upon the achievement of certain net revenue targets by the Iponweb business for the 2022 and 2023 fiscal years. Separate compensation arrangement. The Company transferred Treasury shares with a fair value of $70.2 million to Iponweb's Sellers, subject to lock-up conditions. As these shares are subject to a lock-up period that expires in three installments on each of the first three the $70.2 million fair value was not included in the purchase price consideration above and will be accounted for separately from the business combination as a stock compensation expense. See Note 15 for further discussion. Financing. The acquisition was financed by available cash resources, and in connection with the Acquisition, the Company drew down €50.0 million ($51.1 million) for a one-month period on its then-current revolving credit facility (repaid prior to the quarter-immediately proceeding the acquisition) to provide additional liquidity. Assets acquired and liabilities assumed. The transaction was accounted for as a business acquisition. We have completed the preliminary purchase price allocation and we expect to finalize this analysis within one year from the Acquisition Date. On the Acquisition Date, assets acquired and liabilities assumed by major asset class before purchase price allocation are as follow: Estimated fair values (in millions) Cash and cash equivalents $ 93.3 Trade receivables 100.7 Other current assets 1.1 Technology 90.2 Customer relationships 7.2 Other non-current assets 59.0 Trade Payables (191.5) Other current liabilities (3.1) Other non-current liabilities (54.3) Net assets acquired $ 102.6 Developed technology represents the estimated fair value of the features underlying the Iponweb products as well as the platform providing services to Iponweb customers. Customer relationships represent the estimated fair value of the underlying relationships with Iponweb customers, including the fair value of unbilled and unrecognized contracts yet to be fulfilled. The estimated useful lives of technologies acquired and customer relationships are four In the Iponweb business's opening balance sheet, Criteo recognized a $17.6 million liability related to the Iponweb business's uncertain tax positions in accordance with ASC 740. The Company also recognized a $33.7 million provision in connection with the Iponweb business, accounted for under ASC 450 Contingencies. As part of the Acquisition, the Sellers agreed to indemnify Criteo for losses related to certain liabilities, up to an amount of $50.0 million. As such, we have recognized an indemnification asset of $50.0 million which is recorded as part of "Other non-current assets" on the consolidated statement of financial position. Preliminary goodwill. The Company is assessing the fair value estimate of assets acquired and liabilities assumed as part of the Iponweb Acquisition, based on facts and circumstances that existed as of the Acquisition Date. This measurement period will not exceed one year from the Acquisition Date. The excess of the purchase price over the fair value of net assets acquired is allocated to goodwill. The preliminary goodwill of $187.6 million is primarily attributable to synergies expected to be realized from leveraging our technological capabilities and from the existence of an assembled workforce. Our fair value estimate of assets acquired and liabilities assumed is pending the completion of certain items including the final determination of the purchase price. Accordingly, there could be adjustments to our consolidated financial statements, including changes in our amortization expense related to the valuation of intangible assets and their respective useful lives, among other adjustments. Acquisition costs. Acquisition related costs of $1.1 million and $12.58 million were recorded within general and administrative expenses on the consolidated statements of comprehensive income for the three and twelve months ended December 31, 2022, respectively. Impact on profit and loss. The Company's consolidated statements of operations for the twelve months ended December 31, 2022 includes Iponweb's revenues of $52.2 million and pretax income (loss) of $2.9 million for the period from the Acquisition Date to December 31, 2022. On a pro-forma basis, assuming the Acquisition occurred on January 1, 2021, Criteo's consolidated pro-forma revenue and net income or loss would have been as follows: Pro Forma Consolidated Statement of Operations Data Three Months Ended Twelve months ended December 31, 2022 December 31, 2021 December 31, 2022 December 31, 2021 (in thousands) Revenue $ 565,565 $ 685,396 $ 2,078,109 $ 2,356,377 Net Income (loss) 15,400 69,820 (2,502) $ 117,012 The historical consolidated financial information has been adjusted in the pro forma combined financial statements to give the effect to pro forma events that are directly attributable to the business combination and are reasonably estimable. The pro forma information is for informational purposes only and is not indicative of the results of operations that would have been achieved if the Acquisition had taken place at the beginning the Company's fiscal year 2021.

Segment Reporting [Abstract]
Segment information	Segment information Reportable segments The Company reports segment information based on the "management" approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company's reportable segments. As a result of the Iponweb Acquisition, the Company reassessed its operating and reportable segments in accordance with ASC 280, Segment Reporting. Effective August 1, 2022, the Company reports its results of operations through the following three segments: Marketing Solutions, Retail Media and Iponweb. – Marketing Solutions: This segment allows commerce companies to address multiple marketing goals by engaging their consumers with personalized ads across the web, mobile and offline store environments. – Retail Media: This segment allows 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. – Iponweb: This segment specializes in building real-time advertising technology and trading infrastructure, delivering advanced media buying, selling, and packaging capabilities for media owners, agencies, performance advertisers, and 3rd-party ad tech platforms. Segment operating results, Contribution ex-TAC, is Criteo's segment profitability measure and reflects our gross profit plus other costs of revenue.

ASU 2016- 13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. This results in earlier recognition of credit losses. We adopted ASU 2016-13 effective January 1, 2020 with the cumulative effect of adoption recorded as an adjustment to retained earnings (note 1). We write off accounts receivable balances once the receivables are no longer deemed collectible. During the twelve month period ended December 31, 2022, the Company recovered $3.2 million, previously reserved for, and accounted for this as a reversal of provision. Increase due to acquisition includes $(4.7) million related to the Iponweb acquisition. 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 or impair Customer credit. As of December 31, 2022 and 2021, no customer accounted for 10% or more of trade receivables.

This was partially offset by the $4.7 million accretion of earn-out liability related to Iponweb acquisition. Other impacts come from the foreign exchange reevaluations net of related hedging of our operations, income from cash and cash equivalent, and the financial expense relating to our €407 million available Revolving Credit Facility (RCF) up-front fees amortization and non-utilization costs. At December 31, 2022, 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.

As of December 31, 2022, 2021 and 2020, the valuation allowance against net deferred income taxes amounted to $31.1 million, $35.0 million and $37.3 million, which related mainly to Criteo Corp. ($5.7 million, $5.7 million and $13.3 million, respectively), Criteo Brazil ($3.3 million, $2.7 million and $2.8 million, respectively), Criteo Ltd ($8.1 million, $7.6 million and $7.4 million, respectively), Criteo China ($1.1 million, $3.3 million and $3.3 million, respectively), Criteo Singapore ($1.5 million, $4.2 million and $3.3 million), Criteo Pty ($2.6 million, $2.7 million and $2.8 million) and Criteo France ($6.5 million, $6.2 million and $1.0 million, respectively). The Company mainly has net operating loss carryforwards in the U.S. for $51.0 million in various states, which begin to expire in 2034 and net operating loss carryforwards in the United Kingdom for $40.1 million which have no expiration date. The company has $5.8 million of state R&D tax credits which can be carry-forward indefinitely. Utilization of our net operating loss and tax credit carryforwards in the US may be subject to annual limitations due to the ownership change limitations provided by the IRS Code 382 and similar state provisions. Such annual limitations could result in the expiration of the net operating loss and tax credit carryforwards before their utilization. As of December 31, 2022, we have not provided deferred taxes on unremitted earnings related to foreign subsidiaries. We intend to continue to reinvest these foreign earnings indefinitely and do not expect to incur any significant taxes related to such amounts. Ongoing tax audits As a multinational corporation, we are subject to regular review and audit by U.S. federal and state, and foreign tax authorities. Significant uncertainties exist with respect to the amount of our tax liabilities, including those arising from potential challenges with certain positions we have taken. Any unfavorable outcome of such a review or audit could have an adverse impact on our tax rate. Tax years ending on or after December 31, 2020 are subject to examination in France, and tax years ending on or after December 31, 2020 are subject to examination in the US. Uncertain Tax Positions The following table summarizes the activity related to our gross unrecognized tax benefits during the years ended December 31, 2022 2021 and 2020: Year Ended December 31, 2022 2021 2020 (in thousands) Beginning balance of unrecognized tax benefits $ — $ — $ — Increases related to current year tax positions $ 13,315 — — Ending balance of unrecognized tax benefits (excluding interest and penalties) $ 13,315 — — Interest and penalties associated with unrecognized tax benefits $ 4,665 — — Ending balance of unrecognized tax benefits (including interest and penalties) $ 17,980 — — The total amount of gross unrecognized tax benefits, including related interest and penalties, was $18.0 million as of December 31, 2022. All of the unrecognized tax benefits are considered non-current. Our policy is to recognize interest and penalties associated with tax matters as part of the income tax provision and include accrued interest and penalties with the related income tax liability on our consolidated balance sheet. During the year ended December 31, 2022, interest expense recorded related to uncertain tax positions was $0.4 million Our Uncertain Tax Positions relate to the acquisition of Iponweb. For more information regarding the acquisitions and UTP items please refer to Note 2 Business Combinations. The income taxes we pay are subject to review by taxing jurisdictions globally. Our estimate of the potential outcome of any uncertain tax position is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. We believe that our estimate has adequately provided for these matters. However, our future results may include adjustments to estimates in the period the audits are resolved, which may impact our effective tax rate.

Earnings Per Share [Abstract]
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. Year Ended December 31, 2022 2021 2020 (in thousands, except share data) Net income attributable to shareholders of Criteo S.A. $ 8,952 $ 134,456 $ 71,679 Weighted average number of shares outstanding (note 14) 60,004,707 60,717,446 60,876,480 Basic earnings per share $ 0.15 $ 2.21 $ 1.18 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 20). There were no other potentially dilutive instruments outstanding as of December 31, 2022, 2021 and 2020. 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, share warrant, restricted share award or BSPCE contracts) is assessed as potentially dilutive, if it is “in the money” (i.e., the exercise or settlement price is inferior to the average market price). Year Ended December 31, 2022 2021 2020 (in thousands, except share data) Net income attributable to shareholders of Criteo S.A. $ 8,952 $ 134,456 $ 71,679 Weighted average number of shares outstanding of Criteo S.A. 60,004,707 60,717,446 60,876,480 Dilutive effect of : Restricted share awards 2,554,516 3,061,807 796,609 Share options and BSPCE 117,934 341,971 133,177 Share warrants 83,040 110,413 12,327 Weighted average number of shares outstanding used to determine diluted earnings per share 62,760,197 64,231,637 61,818,593 Diluted earnings per share $ 0.14 $ 2.09 $ 1.16 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: Year Ended December 31, 2022 2021 2020 Restricted share awards 172,758 312,413 1,726,506 Share options and BSPCE — — 70,257 Share warrants — — — Weighted average number of anti-dilutive securities excluded from diluted earnings per share 172,758 312,413 1,796,763

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Purchase Obligations As of December 31, 2022, we had $64.3 million of other non-cancellable contractual obligations, primarily related to software licenses, maintenance and $0.7 million bandwidth for our servers. Contingencies 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, results of operations, financial condition 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. The amount of the provisions represents management’s latest estimate of the expected impact. Regulatory Matters As previously reported in our Annual Report on Form 10-K for the year ended December 31, 2021, in November 2018, Privacy International filed a complaint with certain data protection authorities, including France's Commission Nationale de l'Informatique et des Libertés ("CNIL"), against Criteo and a number of other similarly situated advertising technology companies, arguing that certain of these companies' practices were not in compliance with the European Union's General Data Protection Regulation ("GDPR"). In January 2020, CNIL opened a formal investigation into Criteo in response to this complaint, and on June 23, 2021, CNIL notified the Company of the appointment of an investigator (rapporteur) for the ongoing investigation. The investigation also covers another complaint against Criteo received in November 2018 by CNIL from the European Center for Digital Rights ("NOYB"). On August 3, 2022, the assigned rapporteur issued a report that claimed certain GDPR violations, in particular relating to the Company’s contractual relationships with its advertisers and publishers with respect to consent collection oversight. The report includes a proposed financial sanction against the Company of €60.0 million ($63.9 million).Under the CNIL sanction procedures, Criteo has the right to respond in writing to the report, both with respect to the GDPR findings and the value of the sanction, following which there will be a formal hearing before the CNIL Sanction Committee. The CNIL Sanction Committee will then issue a draft decision that will be submitted for consultation to other European data protection authorities as part of the cooperation mechanism mandated by GDPR. Any final decision, including regarding potential financial penalties, will likely not occur until 2023. Pursuant to U.S. GAAP, we establish accruals for specific legal proceedings when it is considered probable that a loss has been incurred and the amount of the loss can be reasonably estimated, and these accruals are reviewed and adjusted each quarter based on the information available at that time. Given the receipt of this report, which included a proposed sanction penalty of €60.0 million ($63.9 million), we have accounted for the proposed penalty as a provision for a loss contingency, which is reflected in our financial statements for the period ended as of December 31, 2022 as general and administrative expenses. Such amount could be lower or higher based on the final resolution and merits of the claims made in the report. Non income tax risks

Functional Currency and Translation of Financial Statements in Foreign Currency and Conversion of Foreign Currency Transactions	Functional Currency and Translation of Financial Statements in Foreign Currency The Consolidated Financial Statements are presented in U.S. dollars, which differs from the functional currency of the Parent, being the Euro. The statements of financial position of consolidated entities having a functional currency different from the U.S. dollar are translated into U.S. dollars at the closing exchange rate (spot exchange rate at the statement of financial position date) and the statements of income, statements of comprehensive income and statements of cash flow of such consolidated entities are translated at the average period to date exchange rate. The resulting translation adjustments are included in equity under the caption “Accumulated other comprehensive income (loss)” in the Consolidated Statements of Changes in Shareholders' Equity. Conversion of Foreign Currency Transactions Foreign currency transactions are converted to U.S. dollars at the rate of exchange applicable on the transaction date. At period-end, foreign currency monetary assets and liabilities are converted at the rate of exchange prevailing on that date. The resulting exchange gains or losses are recorded in the Consolidated Statements of Income in “Other financial income (expense)” with the exception of exchange differences arising from monetary items that form part of the reporting entity’s net investment in a foreign operation which are recognized in other comprehensive income (loss); they will be recognized in profit or loss on disposal of the net investment.
Use of Estimates	Use of Estimates The preparation of our Consolidated Financial Statements requires the use of estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenue and expenses during the period. We base our estimates and assumptions on historical experience and other factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (1) gross vs net assessment in revenue recognition (2) allowances for credit losses, (3) income taxes, (4) assumptions used in valuing acquired assets and assumed liabilities in business combinations, (5) assumptions used in the valuation of goodwill, intangible assets and leases, (6) assumptions used in the valuation model to determine the fair value of share-based compensation plan, (7) assumptions surrounding the recognition and valuation of contingent liabilities and losses.
Business combinations	Business combinations We include the results of operations of the businesses that we acquire as of the acquisition date. We allocate the purchase price of our acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Intangible Assets	Intangible Assets Acquired intangible assets are accounted for at acquisition cost, less accumulated amortization. Acquired intangible assets are composed of technology and customer relationships amortized on a straight-line basis over their estimated useful lives comprised between three Intangible assets also include costs to develop software to be used solely to meet internal needs and cloud based applications used to deliver our services. We capitalize development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the function intended. Amortization of these costs begins when assets are placed in service and is calculated on a straight-line basis over the assets’ useful lives, generally estimated at three years.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are accounted for at acquisition cost less cumulative depreciation and any impairment loss. Depreciation is calculated on a straight-line basis over the assets’ estimated useful lives as follows: Servers........................................................................................................... 5 years over the life of the warranty Furniture and IT equipments............................................................................................................... 3 to 5 years
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives. The Company evaluates the estimated remaining useful lives of purchased intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as three single reporting units and has selected December 31 as the date to perform its annual impairment test. Goodwill has been allocated to these three segments using a relative fair value allocation approach. In the impairment assessment of its goodwill, the Company performs an impairment test, which involves assumptions regarding estimated future cash flows to be derived from the Company. The estimated future cash flows are used to derive the fair value of the reporting unit, which is then compared to its net book value, including goodwill . If these estimates or their related assumptions change in the future, the Company may be required to record impairment on these assets. If the net book value exceeds its implied fair value, then the Company would be required to recognize an impairment loss in the Consolidated Statement of Income. Acquired intangible assets are accounted for at acquisition cost less cumulative amortization and any impairment loss. Acquired intangible assets are amortized over their estimated useful lives of three
Property, Plant and Equipment and Impairment of Long-Lived Assets	Property, Plant and Equipment and Impairment of Long-lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful life is no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with an asset are less than the carrying amount of the asset, an impairment loss is recorded to write the asset down to its estimated fair value. Fair value is estimated based on discounted future cash flows.
Leases	Leases We lease space under non-cancellable operating leases for our offices and data centers. Our office leases typically include rent free periods and rent escalation periods, and may also include leasehold improvement incentives. Leases for data centers may also include rent free periods and rent escalation periods. 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. Our leases typically contain options to renew, and/or early terminate the lease. Options have been included in the lease term if management has determined it is reasonably certain that they will be exercised, at lease commencement. 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 include changes in indexation and are expensed in the period incurred. We chose to use certain practical expedients upon adaption of ASC 842 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.
Financial Assets and Liabilities, Excluding Derivative Financial Instruments	Financial Assets and Liabilities, Excluding Derivative Financial Instruments Financial assets, excluding cash and cash equivalents, consist exclusively of loans and receivables. Loans and receivables are non-derivative financial assets with a payment, which is fixed or can be determined, not listed on an active market. They are included in current assets, except those that mature more than twelve months after the reporting date. Loans are measured at amortized cost using the effective interest method. The recoverable amount of loans and advances is estimated whenever there is an indication that the asset may be impaired and at least on each reporting date. If the recoverable amount is lower than the carrying amount, an impairment loss is recognized in the Consolidated Statements of Income. Financial liabilities are initially recorded at their fair value at the transaction date. Subsequently they are measured at amortized cost using the effective interest method.
Derivative financial instruments	Derivative financial instruments We buy and sell derivative financial instruments in order to manage and reduce our exposure to the risk of exchange rate fluctuations. We deal only with major financial institutions. Financial instruments may only be classified as hedges when we can demonstrate and document the effectiveness of the hedging relationship at inception and throughout the life of the hedge. Generally, our derivatives are not designated as hedging instruments and mainly consist of forward buying 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, as well as the related costs in the financial income (expense), net, along with the foreign currency gains and losses on monetary assets and liabilities. We report the cash impact of the settlement of hedging derivatives in cash from (used for) financing activities in the consolidated statements of cash flows. This results in the cash flows from derivative instruments to be classified in the same category as the underlying cash flows. Derivatives are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.
Fair value measurements	Fair value measurementsFinancial instruments are presented in three categories based on a hierarchical method used to determine their fair value : (i) level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities; (ii) level 2: fair value calculated using valuation techniques based on observable market data such as prices of similar assets and liabilities or parameters quoted in an active market; (iii) level 3: fair value calculated using valuation techniques based wholly or partially on unobservable inputs such as prices in an active market or a valuation based on multiples for unlisted companies.
Cash, Cash Equivalents and Marketable Securities	Cash, Cash Equivalents and Marketable Securities Cash includes cash on deposit with banks and highly liquid investments such as demand deposits with banks. Cash equivalents include short-term, highly liquid investments, with a remaining maturity at the date of purchase of three months or less for which the risk of changes in value is considered to be insignificant. Highly liquid term deposits therefore meet the definition of cash equivalents. We hold investments in marketable securities, consisting mainly of term deposits with banks, not meeting the cash equivalents definition. We classify marketable securities as either available-for-sale or held-to-maturity investments, depending on whether we have the positive intent and ability to hold the term deposits to maturity. Our available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) in stockholders' equity.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company’s cash and cash equivalents are held and foreign exchange contracts are transacted with major financial institutions that the Company's management has assessed to be of high credit quality. The Company has not experienced any losses in such accounts. The Company mitigates its credit risk with respect to accounts receivable by performing credit evaluations and monitoring agencies' and advertisers' accounts receivable balances. As of December 31, 2022 and 2021 no customer accounted for 10% or more of accounts receivable. During the years ended December 31, 2022, 2021 and 2020, no single customer represented 10% or more of revenue.
Employee Benefits	Employee Benefits Depending on the laws and practices of the countries in which we operate, employees may be entitled to compensation when they retire or to a pension following their retirement. For state-managed plans and other defined contribution plans, we recognize them as expenses when they become payable, our commitment being limited to our contributions. The liability with respect to defined benefit plans is estimated using the following main assumptions: • discount rate; • future salary increases; • employee turnover; and • mortality tables. Service costs are recognized in profit or loss and are allocated by function.
Contingencies	Contingencies An estimated loss from a loss contingency is recognized if the following two conditions are met: • information available before the financial statements are issued indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements; • the amount of loss can be reasonably estimated.
Revenue Recognition and Cost of Revenue	Revenue Recognition We sell personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. We have multiple pricing models which include percentage of spend models in addition to cost-per-click, cost-per-install and cost-per-impression pricing models. Cost-per-click, cost-per-install and cost-per-impression pricing models We recognize revenues when we transfer control of promised services directly to 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, 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, as we consider the delivery of clicks or installs our performance obligation. 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 as we consider the display of advertisements our performance obligation. Percentage of spend models Criteo's Platform enables the buying and selling of retail media with an end-to-end, self-service platform geared toward our brand, agency and retailer customers and is priced using a percentage of spend model. We generate revenues when we provide a platform for the purchase and sale of retail media digital advertising inventory. The platform connects sellers and buyers of retail media inventory, in an online marketplace. Retailers provide advertising inventory to the platform and brands and agencies bid on the retailers digital advertising inventory. Winning bids can create advertising, or paid impressions, which retailers display to their website visitors. The total volume of spending between buyers and sellers on the Company's platform is referred to as working media spend. We charge both the brands and agencies and retailers a contractual fee, based on a percentage of working media spend, for the use of our platform. We recognize revenue when an ad is displayed or clicked on. Criteo's Iponweb solutions offer an online trading platform through which supply partners can submit bid requests for media that they wish to sell, and demand partners can submit bids for media that they wish to buy through the operations of a dynamic, real-time exchange whereby media is sold to demand partners whose bids are selected by supply partners. We generate revenues by charging demand or supply a percentage of total media spend traded through our solutions. We recognize revenue when an ad is displayed or clicked on. Agent vs Principal When a third-party is involved in the delivery of our services to the client, through the supply of digital advertising inventory, we assess whether we act as principal or agent in the arrangement. The assessment is based on the degree we control the specified services at any time before they are transferred to the customer. The determination of whether we are acting as principal or agent requires judgment. We act as principal in our Criteo Marketing Solutions arrangements because (i) we control the advertising inventory before it is transferred to our clients; (ii) we bear sole responsibility in fulfillment of the advertising promise and bear inventory risks and (iii) we have full discretion in establishing prices. Therefore, based on these and other factors, we have determined that we act as principal for our Criteo Marketing Solutions engagements and accordingly report the revenue earned and related costs incurred on a gross basis. We act either as principal or as agent in our Criteo Retail Media segment. For the arrangements related to transactions using our legacy Retail Media solutions, we consider that we act as principal, as we exercise significant control over the client’s advertising campaign. For arrangements related to transactions using our Platform, a self-service solution providing transparency, measurement and control to our brand, agency and retailer customers, we act as agent, because we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a platform fee based on a percentage of the digital advertising inventory purchased through the use of the platform. Therefore, we report the revenue earned and related costs incurred by the Platform solution on a net basis. We act as agent in Iponweb provided solutions as we (i) do not control the advertising inventory before it is transferred to our clients, (ii) do not have inventory risks because we do not purchase the inventory upfront and (iii) have limited discretion in establishing prices as we charge a fee based on a percentage of the digital advertising inventory traded through our solutions. Therefore, we report the revenue earned and related costs incurred by the Iponweb solutions on a net basis. 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. Cost of Revenue Our cost of revenue primarily includes traffic acquisition costs and other cost of revenue. Traffic Acquisition Costs . Traffic acquisition costs consist primarily of purchases of impressions from publishers on a CPM basis. We purchase impressions directly from publishers or third-party intermediaries, such as advertisement exchanges. We recognize cost of revenue on a publisher by publisher basis as incurred. Costs owed to publishers but not yet paid are recorded in our Consolidated Statements of Financial Position as trade payables. For legacy solutions within Criteo Retail Media, we pay for the inventory of our retailer partners on a revenue sharing basis, effectively paying the retailers a portion of the click-based revenue generated by user clicks on the sponsored products advertisements or impressions on the commerce display advertisements displaying the products of our consumer brand clients. For Retail Media Platform solutions, revenue is recognized on a net basis, and there are no associated Traffic Acquisition Costs. For solutions within Iponweb, revenue is recognized on a net basis, and there are no associated Traffic Acquisition Costs. Other Cost of Revenue . Other cost of revenue includes expenses related to third-party hosting fees, depreciation of data center equipment, data purchased from third parties and digital taxes. The Company does not build or operate its own data centers and none of its Research and Development employments are dedicated to revenue generating activities. As a result, we do not include the costs of such personnel in other cost of revenue.
Share-Based Compensation	Share-Based Compensation Shares, employee share options and employee and non-employee warrants are primarily awarded to our employees or directors. These awards are measured at their fair value on the date of grant. The fair value is calculated with the most relevant formula regarding the settlement and the conditions of each plan. The fair value is recorded in personnel expenses (allocated by function in the Consolidated Statements of Income) on a straight-line basis over each milestone composing the vesting period with a corresponding increase in shareholders’ equity. At each closing date, we re-examine the number of options likely to become exercisable. If applicable, the impact of the review of the estimate is recognized in the Consolidated Statements of Income with a corresponding adjustment in equity.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method of accounting. Deferred taxes are recorded on all temporary differences between the financial reporting and tax bases of assets and liabilities, and on tax losses, using the liability method. Differences are defined as temporary when they are expected to reverse within a foreseeable future. We may only recognize deferred tax assets on net operating losses if, based on the projected taxable incomes within the next three years, we determine that it is probable that future taxable profit will be available against which the unused tax losses and tax credits can be utilized. As a result, the measurement of deferred income tax assets is reduced, if necessary, by a valuation allowance for any tax benefits which are not expected to be realized. If future taxable profits are considerably different from those forecasted that support recording deferred tax assets, we will have to revise downwards or upwards the amount of deferred tax assets, which would have a significant impact on our financial results. Tax assets and liabilities are not discounted. Amounts recognized in the Consolidated Financial Statements are calculated at the level of each tax entity included in the consolidation scope. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The French Research Tax Credit, Crédit d’Impôt Recherche (“CIR”), is a French tax incentive to stimulate research and development (“R&D”). Generally, the CIR offsets the income tax to be paid and the remaining portion (if any) can be refunded at the end of a three-fiscal year period. The CIR is calculated based on the claimed volume of eligible R&D expenditures by us. As a result, the CIR is presented as a deduction to “research and development expenses” in the Consolidated Statements of Income, as the CIR is not within the scope of ASC 740. We have exclusively claimed R&D performed in France for purposes of the CIR. As of December 31, 2022, we have offset $14.7 million of CIR tax credits against “research and development expenses” in our Consolidated Statements of Income.
Uncertain Tax Positions	Uncertain Tax Positions We recognize tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. These uncertain tax positions include our estimates for transfer pricing that have been developed based upon analyses of appropriate arms-length prices. Similarly, our estimates related to uncertain tax positions concerning research tax credits are based on an assessment of whether our available documentation corroborating the nature of our activities supporting the tax credits will be sufficient. Although we believe that we have adequately reserved for our uncertain tax positions (including net interest and penalties), we can provide no assurance that the final tax outcome of these matters will not be materially different. We make adjustments to these reserves in accordance with the income tax accounting guidance when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made, and could have a material impact on our financial condition and operating results.
Operating Segments	Operating Segments Segment information reported is built on the basis of internal management data used for performance analysis of businesses and for the allocation of resources (management approach). An operating segment is a component of the Company for which separate financial information is available that is evaluated regularly by our Chief Operating Decision Maker in deciding how to allocate resources and assessing performance. Our chief operating decision-maker is our CEO. The CEO reviews Contribution ex-TAC, primarily at a family of solutions level, for the purposes of allocating resources and evaluating financial performance. Contribution ex-TAC is Criteo's profitability measure and reflects the Company's gross profit plus other costs of revenue.
Earnings Per Share	Earnings Per Share Basic earnings per share (“EPS”) are calculated by dividing the net income attributable to shareholders of the Parent by the weighted average number of shares outstanding. The weighted average number of shares outstanding is calculated according to movements in share capital. In addition, we calculate diluted earnings per share by dividing the net income attributable to shareholders of the Parent company, Criteo S.A. by the weighted average number of shares outstanding plus any potentially dilutive shares not yet issued.
Accounting Pronouncements Adopted in 2022 and Recent Accounting Pronouncements	Accounting Pronouncements adopted in 2022 Effective January 1, 2022, we have adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") Government Assistance (Topic 832): Disclosure by Business Entities about Government Assistance (ASU 2021-10), which improves the transparency of government assistance received by most business entities by requiring the disclosure of: (1) the types of government assistance received; (2) the accounting for such assistance; and (3) the effect of the assistance on a business entity's financial statements. The impacts on our annual consolidated financial statements are limited as a result of adoption of this standard. Recent Accounting Pronouncements Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.

ASU 2016- 13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. This results in earlier recognition of credit losses. We adopted ASU 2016-13 effective January 1, 2020 with the cumulative effect of adoption recorded as an adjustment to retained earnings (note 1).
