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, 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 The preparation of our Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure 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. Actual results could differ from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (1) revenue recognition (2) income taxes, (3) assumptions used in the valuation of long-lived assets including intangible assets, and goodwill, (4) assumptions surrounding the recognition and valuation of contingent liabilities and losses. In January 2025, we completed an assessment of the useful lives of our servers and network equipment, resulting in a change in the estimated useful life of certain servers and network equipment from five to six years . This change in accounting estimate will be effective beginning fiscal year 2025. Operating Segments We report our financial results based on two reportable segments: Retail Media and Performance Media. The reported segment information is based on internal management data used for business performance analysis and resource allocation, following the 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 ("CODM") in deciding how to allocate resources and assessing performance. Beginning in 2024, as a result of the integration of the Iponweb acquisition, the Company has changed its segment reporting structure to two reportable segments: Retail Media and Performance Media, which combines our former Marketing Solutions and Iponweb segments, to align with a change in how the CODM, our Chief Executive Officer (CEO), allocates resources and assesses performance. As such, prior period segment results and related disclosures have been conformed to reflect the Company’s current reportable segments. This change did not impact our results of operations, financial position, or cash flows. Refer to Note 4 for further discussion. 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. Internally Developed Software and Software as a Service Intangible assets 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 i ntended. Amortization of these costs begins when the assets are placed in service and is calculated on a straight-line basis over their lives, generally estimated at three years . Internally developed software and software in progress are periodically reviewed for impairment. Internally developed software deemed no longer in use due to replacements or strategic business decisions are assessed for impairment. The fair value is determined using a future cash flow model. Projects no longer deemed probable of completion are recorded to impairment expense in the period the project is identified as no longer probable of completion. Impairment losses are recorded as Research and Development expense in the Consolidated Statement of Income. Cloud computing arrangements (“CCAs”), such as software as a service ("SaaS") 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 and Equipment Property 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. Management determines the appropriate useful life of property and equipment when those assets are initially recognized and it is routinely reviewed. Our current estimate of useful lives represents the best estimate based on current facts and circumstances, but may differ from the actual useful lives due to changes to our business operations, changes in the planned use of assets, and technological advancements. When we change the estimated useful life assumption for any asset, the remaining carrying amount of the asset is accounted for prospectively and depreciated or amortized over the revised estimated useful life. The estimated useful lives of property and equipment are described below: Servers....................................................................................................................................................... 5 years Furniture and IT equipments............................................................................................................... 3 to 5 years Leasehold improvements are depreciated over their useful life or over the lease term, whichever is shorter. 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. Goodwill and Acquired 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 two reporting units. Goodwill has been allocated to these two reporting units using a relative fair value allocation approach. In 2024 , the Company voluntarily changed its goodwill and indefinite-lived intangible asset annual impairment test date from December 31 to October 1. Refer to Note 10 for further information. In the impairment assessment of its goodwill, the Company performs an impairment test, which involves assumptions regarding estimated future cash flows of 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 to nine years on a straight- line method. Intangible assets are reviewed for impairment whenever events or changes in circumstances such as, but not limited to, significant declines in revenue, earnings or cash flows or material adverse changes in the financial and economic environment indicate that the carrying amount of an asset may be impaired. Leases The Company leases space under noncancellable operating leases for offices and data centers. 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. 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 the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement to determine the present value of future payments. 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. Accounts Receivable 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. The Company applies Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost that an entity does not expect to collect over the asset's contractual life, considering past events, current conditions, and reasonable and supportable forecasts of future economic conditions. For accounts receivable measured at amortized cost, the Company uses aging analysis, and probability of default methods to evaluating and estimating the expected credit losses. A receivable is considered past due if we have not received payments based on agreed-upon terms. Allowances for credit losses on trade receivables are recorded in “Sales and operations expenses” in the Consolidated Statements of Income. The Company generally does not require any security or collateral to support its receivables. Derivative financial instruments The Company buys and sells derivative financial instruments in order to manage and reduce exposure to the risk of exchange rate fluctuations. The Company only deals 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, derivatives are not designated as hedging instruments and mainly consist of forward buying contracts that are use to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the local currency of a subsidiary. The Company recognizes 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. The cash impact of the settlement of hedging derivatives in cash from (used for) financing activities is reported 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. Derivative instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data. Fair value measurements Fair value is defined as the market price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To determine the fair value measurements for assets and liabilities which are required to be recorded at fair value, observable inputs are given preference over unobservable inputs. Fair value measurements are based on the following hierarchy, which prioritizes the inputs used to measure fair value into three levels: • Level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities • 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 • 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 and cash equivalents are comprised of cash on deposit with banks, money market funds and other highly liquid investments such as demand deposits with banks for which the carrying value approximates fair value due to their short-term nature. Cash equivalents include short-term, highly liquid investments, with a remaining maturity at the date of purchase of three months or less, or with a maturity of more than three months that can be early withdrawn without significant penalty or foregoing of interest, for which the risk of changes in value is considered to be insignificant. 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, marketable securities and accounts receivable. The Company’s cash, cash equivalents and marketable securities 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. During the years ended December 31, 2024 , 2023 and 2022 , no individual 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 We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. Certain of these matters might include speculative claims for substantial or indeterminate amounts of damages. With respect to these matters, asserted and unasserted, we evaluate the associated developments on a regular basis and accrue a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. If we determine there is a reasonable possibility that we may incur a loss and the loss or range of loss can be reasonably estimated, we disclose the possible loss in the accompanying notes to the consolidated financial statements to the extent material. We review the developments in our contingencies that could affect the amount of the provisions that have been previously recorded, and the matters and related reasonably possible losses disclosed. Revenue Recognition We sell personalized digital display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. We also provide technology to retailers and other companies in the ad-tech industry which enables them to monetize on their advertising properties, or connect them to other players in the ad-tech industry. Revenue is recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We determine revenue recognition by applying the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; • Recognition of revenue when, or as, we satisfy a performance obligations. 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. Our pricing models include click and impression based pricing, and percentage of spend based pricing. Click and impression based pricing model For campaigns priced on a click or an impression basis, we bill our clients when a user clicks on an advertisement or an advertisement is displayed to a user. For these pricing models, we recognize revenue when a user clicks on an advertisement or an advertisement is displayed, as we consider the delivery of clicks or displays our performance obligation. Percentage of spend model Criteo offers an online trading platform through which brands, agencies, retailers, and supplier can buy and sell digital advertising inventory. Our platform connects sellers and buyers of media inventory in an online marketplace where suppliers provide advertising inventory to the platform and brands and agencies can submit bid requests on digital advertising inventory. The total volume of spending between buyers and sellers on the Company's platform is referred to as working media spend. We charge a fee based on a percentage of working media spend, for the use of our platform. We recognize revenues when customers buy and sell digital advertising inventory through our platform.We also generate revenue through providing additional professional services to our customers, such as billing and administrative services, campaign management, and other transactional services. For performance obligations satisfied over time, we recognize revenue based on a percentage of completion model measured by the outputs transferred to the customer. Principal versus Agent Considerations 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 based on the degree we control the specified services before they are transferred to the customer. To determine whether we are acting as a principal or an agent we assess whether (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. If we determine that we control the service before transferring it to the customer, we conclude we act as principal and accordingly report the revenue earned and related costs incurred on a gross basis. For all other contracts where we do not control the service before transferring to the end customer, we act as an agent and accordingly report the revenue net of related costs incurred. The determination of whether we are acting as principal or agent requires judgment. In our Performance Media segment, we may act as principal or agent depending on the nature of the contract. In our Retail Media segment we act primarily as agent in our Retail Media segment Rebates and Incentives Criteo offers rebates and incentives to certain customers that could be either fixed or variable. Fixed incentives may represent payments to a customer directly related to entering into an agreement, which are capitalized and amortized over the expected life of the agreement on a straight-line basis. Variable rebates and incentives are calculated based on expected amount to be provided to customers and they are recognized as a reduction of revenue. We calculate these amounts based upon estimated customer performance, such as volume thresholds, and the terms of the related business agreements. Contract Assets and Liabilities We record contract liabilities 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. . We record contract assets when we do not yet have unconditional rights to payment. Contract assets and liabilities are presented on a net basis at the contract level. 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. C ost of Revenue Our cost of revenue primarily includes traffic acquisition costs and other cost of revenue. Traffic acquisition costs consist primarily of purchases of impressions from publishers on a CPM basis, incurred to generate our revenues, primarily for the Performance Media segment. 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. Other Cost of Revenue includes expenses related to depreciation of data center equipment, lease cost of data centers, cost of data purchased from third parties, digital taxes, and third-party hosting fees. 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 revenu e. Operating Expenses The Company categorizes its operating expenses into three functional categories: research and development, sales and operations, and general and administrative expenses. Research and development expenses consist primarily of headcount-related expenses for our employees working in the engine, platform, site reliability engineering, scalability, infrastructure, engineering program management, product, analytics and other teams, including salaries, bonuses, share-based compensation and other personnel related costs. Also included are non-personnel costs such as subcontracting, consulting and professional fees to third-party development resources, allocated overhead, including internal IT and depreciation and amortization costs. These expenses are partially offset by the French research tax credit (CIR) that is conditional upon the level of our expenditures in research and development. 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. It is deducted from "Research and development expenses" in the Consolidated Statements of Income. As of December 31, 2024 , 2023 , and 2022 , we recorde d $7.2 million , $9.5 million , and $14.7 million of CIR tax credits against these expenses. Sales and operations expenses consist primarily of headcount-related expenses for our employees working in our sales, account strategy, sales operations, publisher business development, analytics, marketing, technical solutions, creative services and other teams, including salaries, bonuses, share-based compensation, and other personnel-related costs. Additional expenses in this category include travel and entertainment, marketing and promotional events, marketing activities, provisions for doubtful accounts, subcontracting, consulting and professional fees paid to third parties, allocated overhead, including internal IT costs. General and administrative expenses consist primarily of headcount-related expenses, including salaries, bonuses, share-based compensation, pension benefits and other personnel-related costs for our administrative, legal, information technology, human resources, facilities and finance teams. Additional expenses included in this category include travel-related expenses, subcontracting and professional fees, audit fees, tax services and legal fees, as well as insurance and other corporate expenses, along with allocated overhead, including internal IT costs. Advertising and Promotional Expenses Advertising costs are expensed when incurred and are included in marketing and sales expenses on the consolidated statements of income. We incurred advertising expenses o f $1.9 million , $1.7 million , and $7.6 million for the years ended December 31, 2024 , 2023 , and 2022 , respectiv ely. Share-Based Compensation Share-based compensation expense consists of the company's restricted stock units (RSUs), and performance stock units (PSUs) expense and Lock Up Shares "LUS" expense. RSUs and PSUs granted to employees are measured based on the grant-date fair value. The PSUs expense is updated to reflect the Company’s expectatio

Segment Reporting [Abstract]
Segment information	4. Segment information 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. Beginning in the first quarter of 2024, the Company reports its results of operations through the following two segments: Retail Media and Performance Media. – 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. – Performance Media: This segment encompasses commerce activation, monetization, and AdTech services including our media trading marketplace . The Company's CODM allocates resources to and assesses the performance of each operating segment using information about Contribution ex-TAC, which is Criteo's segment profitability measure and reflects our gross profit plus other costs of revenue The CODM only reviews revenues and corresponding TAC for each segment, and does not regularly review any other expense nor financial information for our two segments. T he following table shows revenue by reportable segment : Year Ended December 31, 2024 2023 2022 (in thousands) Retail Media $ 258,303 $ 209,007 $ 202,317 Performance Media 1,674,986 1,740,438 1,814,686 Total Revenue $ 1,933,289 $ 1,949,445 $ 2,017,003 The following table shows TAC by reportable segment: Year Ended December 31, 2024 2023 2022 (in thousands) Retail Media $ 4,457 $ 5,547 $ 40,957 Performance Media 807,349 921,292 1,047,822 Total Traffic Acquisition Cost $ 811,806 $ 926,839 $ 1,088,779 The following table shows Contribution ex-TAC by reportable segment and its reconciliation to the Company’s Consolidated Statements of Operation: Year Ended December 31, 2024 2023 2022 (in thousands) Contribution ex-TAC Retail Media $ 253,846 $ 203,460 $ 161,360 Performance Media 867,637 819,146 766,864 $ 1,121,483 $ 1,022,606 $ 928,224 Other costs of sales 138,512 159,562 133,024 Gross profit $ 982,971 $ 863,044 $ 795,200 Operating expenses Research and development expenses 279,341 242,289 187,596 Sales and operations expenses 376,090 406,012 377,996 General and administrative expenses 176,138 137,525 205,330 Total Operating expenses $ 831,569 $ 785,826 $ 770,922 Income from operations $ 151,402 $ 77,218 $ 24,278 Financial and Other Income (Expense) 3,095 (2,490) 17,783 Income before tax $ 154,497 $ 74,728 $ 42,061 21.

Refer to Note 2 for further discussion. In 2024, the Company voluntarily changed its goodwill annual impairment test date from December 31 to October 1, as it results in better alignment with the Company’s strategic business planning. The voluntary change in accounting principle related to the annual test date did not delay, accelerate or avoid an impairment charge. Retrospective application of this accounting change to prior periods is impracticable as the Company is unable to objectively determine, without the use of hindsight, the significant assumptions and estimates that would be used in those earlier periods. Accordingly, the change is applied prospectively. We conducted our goodwill and indefinite-lived intangible asset impairment testing as of October 1, 2024 and no im pairment has been identified.

The $(2.5) million financial and other expense for the period ended December 31, 2023 was mainly driven by proceeds from disposal of non consolidated investments fully offset by the recognition of a negative impact of foreign exchange, including end of year non-cash marked to market, the accretion of earn-out liability related to Iponweb acquisition and financial expense relating to our €407 million available RCF. The $17.8 million financial and other income for the period ended December 31, 2022 was mainly driven by the positive impact of foreign exchange derivatives entered-into to secure the cash consideration of the Iponweb acquisition. 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 RCF up-front fees amortization and non-utilization costs.

As of December 31, 2024 , 2023 and 2022 , the valuation allowance against net deferred income taxes amounted to $27.6 million , $29.8 million and $31.1 million , which related mainly to Criteo Corp. ( $5.9 million , $5.7 million and $5.7 million , respectively), Criteo Brazil ( $— million , $2.7 million and $3.3 million , respectively), Criteo Ltd ( $9.3 million , $10.7 million and $8.1 million , respectively), Criteo Singapore ( $— million , $1.2 million and $1.5 million , respectively), Criteo Australia Pty ( $2.9 million , $2.9 million and $2.6 million , respectively) and Criteo France ( $8.7 million , $5.0 million and $6.5 million , respectively). The Company mainly ha s net operating loss carryforwar ds in the U.S. for $26.3 million in various states, which begin to expire in 2031 and net operating loss carryforwards in the United Kingdom for $35.4 million , which have no expiration date. The company has $5.9 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, 2024 , 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 French, U.S. federal and state, and other 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. Uncertain Tax Positions The following table summarizes the activity related to our gross unrecognized tax benefits during the years ended December 31, 2024 , 2023 and 2022 : Year Ended December 31, 2024 2023 2022 (in thousands) Beginning balance of unrecognized tax benefits $ 12,229 $ 13,315 $ — Increases (Decreases) related to current year tax positions 199 (1,086) 13,315 Ending balance of unrecognized tax benefits (excluding interest and penalties) 12,428 12,229 13,315 Interest and penalties associated with unrecognized tax benefits 5,589 4,556 4,665 Ending balance of unrecognized tax benefits (including interest and penalties) $ 18,017 $ 16,785 $ 17,980 The total amount of gross unrecognized tax benefits, including related interest and penalties, was $18.0 million as of December 31, 2024 . All of the unrecognized tax benefits are considered noncurrent. 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. Pillar Two In December 2021, the Organization for Economic Cooperation and Development (OECD) released Pillar Two Model Rules defining the global minimum tax, which calls for the taxation of a minimum rate of 15% for multinational companies with consolidated revenue above €750 million. Numerous jurisdictions have enacted or are in the process of enacting legislation to adopt a minimum effective tax rate. As of December 31, 2024 , the adoption of Pillar Two resulted in an impact of $3.0 million recognized in Provision for income taxes within the Consolidated Statement of Operations . The Company will continue to assess the ongoing impact of Pillar Two as additional guidance becomes available.

Earnings Per Share	19. 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, 2024 2023 2022 (in thousands, except share data) Net income attributable to shareholders of Criteo S.A. $ 111,571 $ 53,259 $ 8,952 Weighted average number of shares outstanding ( Note 15 ) 54,817,136 56,170,658 60,004,707 Basic earnings per share $ 2.04 $ 0.95 $ 0.15 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 15 ). There were no other potentially dilutive instruments outstanding as of December 31, 2024 , 2023 and 2022 . 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, or restricted share award) 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, 2024 2023 2022 (in thousands, except share data) Net income attributable to shareholders of Criteo S.A. $ 111,571 $ 53,259 $ 8,952 Weighted average number of shares outstanding of Criteo S.A. 54,817,136 56,170,658 60,004,707 Dilutive effect of : Restricted share awards ("RSUs") 2,904,711 2,643,129 2,554,516 Lock-up shares ("LUSs") 711,941 1,261,947 — Share options and BSPCE 112,491 104,294 117,934 Share warrants 59,250 51,599 83,040 Weighted average number of shares outstanding used to determine diluted earnings per share 58,605,529 60,231,627 62,760,198 Diluted earnings per share $ 1.90 $ 0.88 $ 0.14 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, 2024 2023 2022 Restricted share awards 236,039 348,675 172,758 Share options and BSPCE — — — Weighted average number of anti-dilutive securities excluded from diluted earnings per share 236,039 348,675 172,758

Commitments and contingencies	20. Commitments and contingencies Contractual Commitments We have $76.8 million of non-cancelable contractual commitments as of December 31, 2024 , which are primarily related to software licenses, maintenance and bandwidth for our servers. The following is a schedule, by years, of non-cancelable contractual commitments as of December 31, 2024 : Total (in thousands) 2025 $ 58,027 2026 17,782 2027 946 Total $ 76,755 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. Legal and R egulatory Matters Following a complaint from Privacy International against a number of advertising technology companies with certain data protection authorities, including in France, France's Commission Nationale de l'Informatique et des Libertés (the "CNIL") opened a formal investigation in January 2020 against Criteo. In June 2023, the CNIL issued its decision, which retained alleged European Union's General Data Protection Regulation ("GDPR") violations but reduced the financial sanction against Criteo from the original amount of €60 million ( $64.2 million ) to €40 million ( $43.3 million ). Criteo issued the required sanction payment during the third quarter of 2023. The decision relates to past matters and does not include any obligation for Criteo to change its current practices. Criteo has appealed this decision before the French Council of State (Conseil d’Etat). We are party to a claim (Doe v. GoodRx Holdings, Inc. et al. in the U.S. District Court for the Northern District of California), alleging violations of various state and federal laws. We intend to vigorously defend our position, but we are unable to predict the potential outcome at this time. Non income tax risks We have recorded a $31.9 million provision related to certain non income tax items accounted for under ASC 450 Contingencies . These risks were identified and recognized as part of the Iponweb Acquisition in 2022. We have recorded an indemnification asset in the full amount of the provision as the Company is indemnified against certain tax liabilities under the purchase agreement for the Iponweb Acquisition. The indemnification asset is recorded as part of "Other noncurrent assets" on the consolidated statement of financial position.

Segment Reporting [Abstract]
Disaggregation of Revenue and Noncurrent Assets	4. Segment information 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. Beginning in the first quarter of 2024, the Company reports its results of operations through the following two segments: Retail Media and Performance Media. – 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. – Performance Media: This segment encompasses commerce activation, monetization, and AdTech services including our media trading marketplace . The Company's CODM allocates resources to and assesses the performance of each operating segment using information about Contribution ex-TAC, which is Criteo's segment profitability measure and reflects our gross profit plus other costs of revenue The CODM only reviews revenues and corresponding TAC for each segment, and does not regularly review any other expense nor financial information for our two segments.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Criteo recognizes the critical importance of maintaining the safety and security of our systems and data and has a holistic process for overseeing and managing cybersecurity and related risks. Our security program is led by our Chief Information Security Officer (“CISO”) , who reports directly to our Chief Technology Officer (“CTO”), who is responsible for managing cybersecurity risks as well as protecting our products, networks and systems. Our CISO has extensive information technology and program management experience and has served many years in our corporate information security organization. Our CISO manages our security organization, which is composed of dedicated teams of experts in security engineering, incident response, compliance, and software development. Risk Management Our security team has several touch points within the business in order to adequately address and mitigate risks. For instance, the team provides mandatory cybersecurity awareness training for all employees and a recurring phishing campaign. Our technical security teams use a combination of threat intelligence tools, defensive tools and proactive testing to detect vulnerabilities and respond. Our technical security teams also invest in building new tools and integrating solutions to improve our security posture on an ongoing basis. Our security compliance teams perform third-party risk assessments , respond to client inquiries about security, help the business to manage our security controls, and translate our external requirements into policies, standards, and actions for the rest of our business. Various parts of our team also participate in risks assessments during project kick-offs. With regards to third-party risk assessments, our process involves assessing how third parties interact and connect with our information systems and our data, assessing the security of the third-party (including through questionnaires), and obtaining independent proofs of security (including via security certification and/or penetration tests) depending on the associated level of risk, as evaluated by our team. Our procurement teams also run checks to ensure vendors are not sanctioned or otherwise identified as potentially corrupt. The process of assessing, identifying and managing cybersecurity related risks is integrated into our overall ERM via a dedicated Information Security Risk Management program that is focused on cybersecurity risk and run by our security compliance team. Risks that are identified through our security processes go through a process of analysis, prioritization, treatment and monitoring. During the lifecycle of cybersecurity specific risks, risk owners, working alongside the security compliance team, are assigned to develop risk mitigation plans, which are followed by the team until a risk is sufficiently mitigated or resolved, at which point such risk reaches a monitoring state. Cybersecurity risks are aggregated into strategic business risks and incorporated into the ERM program. Cybersecurity Incidents While we have experienced cybersecurity incidents in the past, there have been none to date which have materially affected, or are reasonably likely to materially affect, the Company, our financial position, results of operations and/or cash flows. We continue to invest in the cybersecurity and resiliency of our networks and to enhance our internal controls and processes, which are designed to help protect our systems and infrastructure, and the information they contain. For more information regarding the risks we face from cybersecurity threats, please see “Item 1A. Risk Factors – Risks Related to Data Privacy, Intellectual Property and Cybersecurity.”

Cybersecurity Risk Board of Directors Oversight [Text Block]	Governance Our Board of Directors is primarily responsible for the oversight of our risk management activities and has delegated to the Audit Committee the responsibility to assist in this task. The Audit Committee regularly reviews and discusses with management and, as appropriate, the Company’s auditors, the Company’s guidelines and policies with respect to risk assessment and risk management, including the Company’s data privacy and cybersecurity risk exposures and the steps taken to monitor and manage those exposures. The CISO helps maintain a comprehensive security program that serves as a governance framework for information security at Criteo, supports the business goals of the company and details, across problem spaces and security core functions, the various initiatives, their scope, the associated risks and weaknesses, the roadmap and the current progress. Criteo assesses and manages its cybersecurity risks in part through an executive committee referred to as t he Governance Risk and Compliance Committee (the “GRCC”). The GRCC is composed of the CISO and certain members of our executive and leadership teams, and meets several times a year to discuss strategic information security matters including the security program, major risks and incidents and significant key performance indicators (“KPIs”). As a member of the GRCC, the CISO briefs the Audit Committee on the information security program, major risks and any cybersecurity incidents, typically at least annually. Additionally, cybersecurity risks are reported to the Board of Directors, at least annually, as part of Criteo’s enterprise risk mapping (“ERM”) program. Quality Control of Security To help ensure that our security program functions in line with industry expectations, Criteo invests in identifying and remediating gaps in our security posture. To accomplish this, we use a mix of our internal expertise and external third- party expertise, as needed, to audit ourselves against industry standards, such as the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, International Organization for Standardization 27001 Information Security Management System Requirements (“ISO27001”) and the American Institute of Certified Public Accountants’ Service Organization Control Type 2 (“AICPA SOC 2”). Various parts of our business maintain independently assessed security certifications, and we also run certification programs to expand the scope of our existing security certifications .

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, 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 in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure 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. Actual results could differ from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (1) revenue recognition (2) income taxes, (3) assumptions used in the valuation of long-lived assets including intangible assets, and goodwill, (4) assumptions surrounding the recognition and valuation of contingent liabilities and losses. In January 2025, we completed an assessment of the useful lives of our servers and network equipment, resulting in a change in the estimated useful life of certain servers and network equipment from five to six years . This change in accounting estimate will be effective beginning fiscal year 2025.
Operating Segments	Operating Segments We report our financial results based on two reportable segments: Retail Media and Performance Media. The reported segment information is based on internal management data used for business performance analysis and resource allocation, following the 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 ("CODM") in deciding how to allocate resources and assessing performance. Beginning in 2024, as a result of the integration of the Iponweb acquisition, the Company has changed its segment reporting structure to two reportable segments: Retail Media and Performance Media, which combines our former Marketing Solutions and Iponweb segments, to align with a change in how the CODM, our Chief Executive Officer (CEO), allocates resources and assesses performance. As such, prior period segment results and related disclosures have been conformed to reflect the Company’s current reportable segments. This change did not impact our results of operations, financial position, or cash flows. Refer to Note 4 for further discussion.
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.
Internally Developed Software and Software as a Service	Internally Developed Software and Software as a Service Intangible assets 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 i ntended. Amortization of these costs begins when the assets are placed in service and is calculated on a straight-line basis over their lives, generally estimated at three years . Internally developed software and software in progress are periodically reviewed for impairment. Internally developed software deemed no longer in use due to replacements or strategic business decisions are assessed for impairment. The fair value is determined using a future cash flow model. Projects no longer deemed probable of completion are recorded to impairment expense in the period the project is identified as no longer probable of completion. Impairment losses are recorded as Research and Development expense in the Consolidated Statement of Income. Cloud computing arrangements (“CCAs”), such as software as a service ("SaaS") 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 and Equipment	Property and Equipment Property 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. Management determines the appropriate useful life of property and equipment when those assets are initially recognized and it is routinely reviewed. Our current estimate of useful lives represents the best estimate based on current facts and circumstances, but may differ from the actual useful lives due to changes to our business operations, changes in the planned use of assets, and technological advancements. When we change the estimated useful life assumption for any asset, the remaining carrying amount of the asset is accounted for prospectively and depreciated or amortized over the revised estimated useful life. The estimated useful lives of property and equipment are described below: Servers....................................................................................................................................................... 5 years Furniture and IT equipments............................................................................................................... 3 to 5 years Leasehold improvements are depreciated over their useful life or over the lease term, whichever is shorter. 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.
Goodwill and Acquired Intangible Assets	Goodwill and Acquired 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 two reporting units. Goodwill has been allocated to these two reporting units using a relative fair value allocation approach. In 2024 , the Company voluntarily changed its goodwill and indefinite-lived intangible asset annual impairment test date from December 31 to October 1. Refer to Note 10 for further information. In the impairment assessment of its goodwill, the Company performs an impairment test, which involves assumptions regarding estimated future cash flows of 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 to nine years on a straight- line method. Intangible assets are reviewed for impairment whenever events or changes in circumstances such as, but not limited to, significant declines in revenue, earnings or cash flows or material adverse changes in the financial and economic environment indicate that the carrying amount of an asset may be impaired.
Leases	Leases The Company leases space under noncancellable operating leases for offices and data centers. 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. 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 the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement to determine the present value of future payments. 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.
Accounts Receivables	Accounts Receivable 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. The Company applies Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost that an entity does not expect to collect over the asset's contractual life, considering past events, current conditions, and reasonable and supportable forecasts of future economic conditions. For accounts receivable measured at amortized cost, the Company uses aging analysis, and probability of default methods to evaluating and estimating the expected credit losses. A receivable is considered past due if we have not received payments based on agreed-upon terms. Allowances for credit losses on trade receivables are recorded in “Sales and operations expenses” in the Consolidated Statements of Income. The Company generally does not require any security or collateral to support its receivables.
Derivative financial instruments	Derivative financial instruments The Company buys and sells derivative financial instruments in order to manage and reduce exposure to the risk of exchange rate fluctuations. The Company only deals 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, derivatives are not designated as hedging instruments and mainly consist of forward buying contracts that are use to hedge intercompany transactions and other monetary assets or liabilities denominated in currencies other than the local currency of a subsidiary. The Company recognizes 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. The cash impact of the settlement of hedging derivatives in cash from (used for) financing activities is reported 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. Derivative instruments are considered level 2 financial instruments as they are measured using valuation techniques based on observable market data.
Fair value measurements	Fair value measurements Fair value is defined as the market price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To determine the fair value measurements for assets and liabilities which are required to be recorded at fair value, observable inputs are given preference over unobservable inputs. Fair value measurements are based on the following hierarchy, which prioritizes the inputs used to measure fair value into three levels: • Level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities • 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 • 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 and cash equivalents are comprised of cash on deposit with banks, money market funds and other highly liquid investments such as demand deposits with banks for which the carrying value approximates fair value due to their short-term nature. Cash equivalents include short-term, highly liquid investments, with a remaining maturity at the date of purchase of three months or less, or with a maturity of more than three months that can be early withdrawn without significant penalty or foregoing of interest, for which the risk of changes in value is considered to be insignificant. 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	Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. The Company’s cash, cash equivalents and marketable securities 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. During the years ended December 31, 2024 , 2023 and 2022 , no individual 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. 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	Contingencies We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. Certain of these matters might include speculative claims for substantial or indeterminate amounts of damages. With respect to these matters, asserted and unasserted, we evaluate the associated developments on a regular basis and accrue a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. If we determine there is a reasonable possibility that we may incur a loss and the loss or range of loss can be reasonably estimated, we disclose the possible loss in the accompanying notes to the consolidated financial statements to the extent material. We review the developments in our contingencies that could affect the amount of the provisions that have been previously recorded, and the matters and related reasonably possible losses disclosed.
Revenue Recognition and Cost of Revenue	Revenue Recognition We sell personalized digital display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. We also provide technology to retailers and other companies in the ad-tech industry which enables them to monetize on their advertising properties, or connect them to other players in the ad-tech industry. Revenue is recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We determine revenue recognition by applying the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; • Recognition of revenue when, or as, we satisfy a performance obligations. 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. Our pricing models include click and impression based pricing, and percentage of spend based pricing. Click and impression based pricing model For campaigns priced on a click or an impression basis, we bill our clients when a user clicks on an advertisement or an advertisement is displayed to a user. For these pricing models, we recognize revenue when a user clicks on an advertisement or an advertisement is displayed, as we consider the delivery of clicks or displays our performance obligation. Percentage of spend model Criteo offers an online trading platform through which brands, agencies, retailers, and supplier can buy and sell digital advertising inventory. Our platform connects sellers and buyers of media inventory in an online marketplace where suppliers provide advertising inventory to the platform and brands and agencies can submit bid requests on digital advertising inventory. The total volume of spending between buyers and sellers on the Company's platform is referred to as working media spend. We charge a fee based on a percentage of working media spend, for the use of our platform. We recognize revenues when customers buy and sell digital advertising inventory through our platform.We also generate revenue through providing additional professional services to our customers, such as billing and administrative services, campaign management, and other transactional services. For performance obligations satisfied over time, we recognize revenue based on a percentage of completion model measured by the outputs transferred to the customer. Principal versus Agent Considerations 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 based on the degree we control the specified services before they are transferred to the customer. To determine whether we are acting as a principal or an agent we assess whether (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. If we determine that we control the service before transferring it to the customer, we conclude we act as principal and accordingly report the revenue earned and related costs incurred on a gross basis. For all other contracts where we do not control the service before transferring to the end customer, we act as an agent and accordingly report the revenue net of related costs incurred. The determination of whether we are acting as principal or agent requires judgment. In our Performance Media segment, we may act as principal or agent depending on the nature of the contract. In our Retail Media segment we act primarily as agent in our Retail Media segment Rebates and Incentives Criteo offers rebates and incentives to certain customers that could be either fixed or variable. Fixed incentives may represent payments to a customer directly related to entering into an agreement, which are capitalized and amortized over the expected life of the agreement on a straight-line basis. Variable rebates and incentives are calculated based on expected amount to be provided to customers and they are recognized as a reduction of revenue. We calculate these amounts based upon estimated customer performance, such as volume thresholds, and the terms of the related business agreements. Contract Assets and Liabilities We record contract liabilities 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. . We record contract assets when we do not yet have unconditional rights to payment. Contract assets and liabilities are presented on a net basis at the contract level. 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. C ost of Revenue Our cost of revenue primarily includes traffic acquisition costs and other cost of revenue. Traffic acquisition costs consist primarily of purchases of impressions from publishers on a CPM basis, incurred to generate our revenues, primarily for the Performance Media segment. 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. Other Cost of Revenue includes expenses related to depreciation of data center equipment, lease cost of data centers, cost of data purchased from third parties, digital taxes, and third-party hosting fees. 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 revenu e. Operating Expenses The Company categorizes its operating expenses into three functional categories: research and development, sales and operations, and general and administrative expenses. Research and development expenses consist primarily of headcount-related expenses for our employees working in the engine, platform, site reliability engineering, scalability, infrastructure, engineering program management, product, analytics and other teams, including salaries, bonuses, share-based compensation and other personnel related costs. Also included are non-personnel costs such as subcontracting, consulting and professional fees to third-party development resources, allocated overhead, including internal IT and depreciation and amortization costs. These expenses are partially offset by the French research tax credit (CIR) that is conditional upon the level of our expenditures in research and development. 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. It is deducted from "Research and development expenses" in the Consolidated Statements of Income. As of December 31, 2024 , 2023 , and 2022 , we recorde d $7.2 million , $9.5 million , and $14.7 million of CIR tax credits against these expenses. Sales and operations expenses consist primarily of headcount-related expenses for our employees working in our sales, account strategy, sales operations, publisher business development, analytics, marketing, technical solutions, creative services and other teams, including salaries, bonuses, share-based compensation, and other personnel-related costs. Additional expenses in this category include travel and entertainment, marketing and promotional events, marketing activities, provisions for doubtful accounts, subcontracting, consulting and professional fees paid to third parties, allocated overhead, including internal IT costs. General and administrative expenses consist primarily of headcount-related expenses, including salaries, bonuses, share-based compensation, pension benefits and other personnel-related costs for our administrative, legal, information technology, human resources, facilities and finance teams. Additional expenses included in this category include travel-related expenses, subcontracting and professional fees, audit fees, tax services and legal fees, as well as insurance and other corporate expenses, along with allocated overhead, including internal IT costs. Advertising and Promotional Expenses Advertising costs are expensed when incurred and are included in marketing and sales expenses on the consolidated statements of income. We incurred advertising expenses o f $1.9 million , $1.7 million , and $7.6 million for the years ended December 31, 2024 , 2023 , and 2022 , respectiv ely.
Share-Based Compensation	Share-Based Compensation Share-based compensation expense consists of the company's restricted stock units (RSUs), and performance stock units (PSUs) expense and Lock Up Shares "LUS" expense. RSUs and PSUs granted to employees are measured based on the grant-date fair value. The PSUs expense is updated to reflect the Company’s expectation of the likelihood of meeting the performance conditions of the granted instrument. In general, our RSUs and PSUs vest over a service period of four years . LUS were issued to Iponweb seller as partial consideration for the Iponweb Acquisition. Share-based compensation expense is generally recognized based on the straight-line basis over the requisite service period. We account for forfeitures as they occur.
Financial and Other Income (Expense)	Financial and Other Income (Expense) Financial and other income (expense) consists of investment gains and losses, foreign currency exchange differences, and interest income and expenses.
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 an 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 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&D performed in the U.S. for purposes of the U.S. Research Tax Credit.
Uncertain Tax Positions	Uncertain Tax Positions We record uncertain tax positions on the basis of a two-step process in which determinations are made (i) whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with a tax authority. We recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in our consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.
Earnings Per Share	Earnings Per Share Basic earnings per share (“EPS”) is 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. When the statement of income presents a loss position, basic net loss is the same as diluted net loss per share as the inclusion of all potential shares of common stock outstanding would be anti-dilutive.
Reclassification	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. In 2024, the Company changed the presentation of value-added tax ("VAT") receivables and payables within Other taxes in the Consolidated Statement of Financial Position from a gross to a net presentation. VAT receivables are netted with VAT payables within the same jurisdiction when there is a legal right to offset and the Company has the intent to settle on a net basis. For the fiscal year ended December 31, 2023, this change resulted in a reclassification of $40.4 million betwe en Other Taxes Receivables and Other Taxes Payable. The reclassification had no impact on net income, comprehensive income, or shareholders’ equity.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) Issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The ASU requires that an entity disclose significant segment expenses impacting profit and loss that are regularly provided to the CODM. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which improves the transparency of income tax disclosures. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The new standard is effective for annual periods beginning after December 15, 2024. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income— Expense Disaggregation Disclosures, which requires disaggregated disclosure of income statement expenses. This standard is effective for annual periods beginning after December 15, 2026, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
