 Special Note Regarding Forward-Looking Statements
 This Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that are based on our management's beliefs and assumptions and on information currently available to our management. All statements other than present and historical facts and conditions contained in this Form 10-K, including statements regarding our future results of operations and financial position, business strategy, plans and our objectives for future operations, are forward-looking statements. When used in this Form 10-K, the words "anticipate," "believe," "can," "could," "estimate," "expect," "intend," "is designed to," "may," "might," "objective," "plan," "potential," "predict," "project," "seek," "should," "will," "would" or the negative of these and similar expressions identify forward-looking statements.
 You should refer to Item 1A "Risk Factors" of this Form 10-K for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Form 10-K will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame or at all. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
 You should read this Form 10-K and the documents that we reference in this Form 10-K and have filed as exhibits to this Form 10-K completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.
 This Form 10-K contains market data and industry forecasts that were obtained from industry publications. These data and forecasts involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such information. We have not independently verified any third-party information. While we believe the market position, market opportunity and market size information included in this Form 10-K is generally reliable, such information is inherently imprecise.

 Summary Risk Factors
 Investing in our securities involves a high degree of risk. You should carefully consider the risks and uncertainties described in "Item 1A. Risk Factors", which are summarized below:
 • If we fail to innovate, enhance our brand, adapt and respond effectively to rapidly changing technology, our offerings may become less competitive or obsolete. Our investments in new solutions and technologies to address new marketing goals for our clients are inherently risky and may not be successful.
 • The market in which we participate is intensely competitive, and we may not be able to compete successfully with our current or future competitors.
 • Our success depends on our ability to implement our business transformation and achieve our global business strategies.
 • The failure by Criteo AI Engine to accurately predict engagement by users and maintain the quality of our client and publisher content could result in significant costs to us, lost revenue and diminished business opportunities.
 • Third parties may implement technical restrictions that impede our access to data and revenue opportunities upon which we rely, which could materially impact our business and results of operations.
 • Our ability to generate revenue depends on our collection of significant amounts of data from various sources, which may be restricted by consumer choice, clients, publishers, browsers or other software, changes in technology, and new developments in laws, regulations and industry standards.
 • Our international operations and expansion expose us to several risks.
 • Regulatory, legislative or self-regulatory developments regarding internet or online matters could adversely affect our ability to conduct our business.
 • We may not be able to effectively integrate the businesses we acquire, which may adversely affect our ability to achieve our growth and business objectives.
 • We have substantial client concentration in certain local markets and solutions, with a limited number of clients accounting for a substantial portion of our revenues in those areas.
 • We operate in a rapidly evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful. Our historical growth rates may not be indicative of our future growth, and we may have difficulty sustaining profitability.
 • We derive a significant portion of our revenue from companies in the retail, travel and classified industries, and any downturn in these industries or any changes in regulations affecting these industries could harm our business.
 • Our future success will depend in part on our ability to expand into new industry verticals.
 • As we expand the market for our solutions, we may become more dependent on advertising agencies as intermediaries, which may adversely affect our ability to attract and retain business.
 • Our future success will depend in part on our ability to expand into new advertising channels.
 • We experience fluctuations in our results of operations due to a number of factors, which make our future results difficult to predict and could cause our operating results to fall below expectations or our guidance.
 • We face intense competition for employee talent, and if we do not retain and continue to attract highly skilled talent or retain our senior management team and other key employees, we may not be able to achieve our business objectives.
 • Our business involves the use, transmission and storage of personal data and confidential information, and the failure to properly safeguard such information could result in significant reputational harm and monetary damages.
 • Failures in the systems and infrastructure supporting our solutions and operations, including as we scale our offerings, could significantly disrupt our operations and cause us to lose clients.
 • If we are unable to protect our proprietary information or other intellectual property, our business could be adversely affected.
 • Our business may suffer if it is alleged or determined that our technology or another aspect of our business infringes the intellectual property rights of others.
 • Our inability to use software licensed from third parties, or our use of open source software under license terms that interfere with our proprietary rights, could disrupt our business.
 • The market price for the ADSs has been and may continue to be volatile or may decline regardless of our operating performance.
 • We may need additional capital in the future to meet our financial obligations and to pursue our business objectives. Additional capital may not be available on favorable terms, or at all, which could compromise our ability to meet our financial obligations and grow our business.
 • Our business could be negatively impacted by the activities of hedge funds or short sellers.
 • Our credit agreement contains, and future debt agreements may contain, restrictions that may limit our flexibility in operating our business.

 • We do not currently intend to pay dividends on our securities and, consequently, the ability to achieve a return on your investment will depend on appreciation in the price of the ADSs. In addition, French law may limit the amount of dividends we are able to distribute.
 • Our by-laws and French corporate law contain provisions that may delay or discourage a sale of the Company.
 • You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.
 • Your right as a holder of ADSs to participate in any future preferential subscription rights or to elect to receive dividends in shares may be limited, which may cause dilution to your holdings.
 • You may be subject to limitations on the transfer of your ADSs and the withdrawal of the underlying ordinary shares.
 • U.S. investors may have difficulty enforcing civil liabilities against our Company and directors and senior management.
 • The rights of shareholders in companies subject to French corporate law differ in material respects from the rights of shareholders of corporations incorporated in the U.S.
 • In periods of macroeconomic and geopolitical uncertainty beyond our control, businesses may delay or reduce their spending on advertising, which may expose us to the credit risk of some of our clients and adversely affect our business, financial condition, results of operations and/or cash flows.
 • If we fail to maintain an effective system of internal controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of the ADSs may, therefore, be adversely impacted.
 • Our failure to maintain certain tax regimes applicable to French technology companies may adversely affect our results of operations.
 • We are a multinational organization facing increasingly complex tax issues in many jurisdictions, and new taxes or laws, or revised interpretations thereof, that may negatively affect our results of operations.
 • U.S. holders of our ADSs may suffer adverse tax consequences if we are treated as a "passive foreign investment company" for U.S. federal income tax purposes.
 • If a U.S. holder is treated as owning at least 10% of our ADSs, such person may be subject to adverse U.S. federal income tax consequences.

 Item 1. Business
 History and Development of the Company
 Criteo S.A. was initially incorporated as a soci t par actions simplifi e, or S.A.S., under the laws of the French Republic on November 3, 2005, for a period of 99 years and subsequently converted to a soci t anonyme, or S.A. We are registered at the Paris Commerce and Companies Register under the number 484 786 249. Our agent for service of process in the United States ("U.S.") is National Registered Agents, Inc.
 Business Overview
 We are the global Commerce Media company that enables marketers and media owners to drive better commerce outcomes. We leverage commerce data and artificial intelligence ("AI") to connect ecommerce, digital marketing and media monetization to reach consumers throughout their shopping journey. Our vision is to bring richer experiences to every consumer by supporting a fair and open internet that enables discovery, innovation, and choice – powered by trusted and impactful advertising. Since 2018, and accelerating since 2020, we have deeply transformed the Company from a single-product to a multi-solution platform provider, diversifying our business.
 We enable brands', retailers' and media owners' growth by providing best-in-class marketing and monetization services and infrastructure on the open Internet, driving approximately $29 billion of commerce outcomes for our customers – in the form of product sales for retailers, brands and marketers and advertising revenues for media owners. We differentiate ourselves by delivering the best performing commerce audiences at scale and we deliver this value by activating commerce data in a privacy-by-design way through proprietary AI technology to reach and engage consumers in real time with highly relevant digital advertisements ("ads") based on shared characteristics across all stages of the consumer journey. Our data offers deep insights into consumer intent and purchasing habits.

 Our focus is on commerce media. As of December 31, 2023, we served approximately 18,000 clients including many of the largest and most sophisticated consumer brands, retailers, commerce companies and media owners in the world. We partner with them to capture user activity on their websites and mobile applications ("apps"), which we define as digital properties, and leverage that data to deliver superior ad performance to help marketers, brands and agencies reach their campaign objectives from top to bottom of the marketing funnel. This includes powering the retail media ecosystem as we enable brands to reach shoppers with relevant ads near the digital point of sale on retailer and marketplace websites while enabling retailers to monetize their ad inventory and add a new, high margin revenue stream. In each of the last three years, our average client retention rate, as measured on a quarterly basis, was approximately 90%.

 Demonstrating the depth and scale of our commerce data, we have exposure to $1 trillion in online sales transactions on our clients' digital properties in the year ended December 31, 2023. Based on this data and other assets, we activated over $4 billion of media spend on behalf of our clients and delivered 1.9 trillion targeted ads in the year ended December 31, 2023.

 We have established our leading market position in commerce media by focusing on three key assets that differentiate us: actionable commerce data, extensive media access, and world-class predictive AI technology. Our large dataset is uniquely focused on commerce and shoppers, our media access across our broad direct network of media owner partners provides large consumer reach as we see approximately 700 million daily active users, and our purpose-built AI technology activates this data and media to drive multiple commerce outcomes for our customers.

 Each day, we are presented with billions of opportunities to connect consumers with relevant advertising messages from our commerce and consumer brand clients in compliance with the highest privacy standards, including the General Data Protection Regulation ("GDPR") and California Consumer Privacy Act ("CCPA"). For each of these opportunities, our algorithms analyze massive volumes of shopping data to predict consumer preferences and intent, and deliver specific messaging for products or services that are likely to engage that particular consumer. The accuracy of our algorithms improves with every ad we deliver, as they incorporate new data while continuing to learn from prior interactions.

 Industry Trends

 We operate in commerce media, the fourth wave in digital advertising after display, search and social, leveraging our performance assets along with our Retail Media expertise to deliver impactful ads and reach consumers throughout their shopping journey, when they are the most willing to purchase.
 We believe the following trends are relevant in assessing our current and future business:
 Ecommerce is Booming: According to eMarketer, global retail ecommerce penetration is expected to grow to 23% in 2027, up from 19% in 2023. Ecommerce growth creates more advertising inventory in places where commerce audiences are, and it increases our ability to attract more ad spend. We are ideally positioned to complement Amazon and enable brands, agencies and retailers to activate commerce beyond Amazon, an opportunity which represents approximately 73% of consumers' online shopping1.
 First-Party Data Unlocks Huge Potential: Retailers leverage their shoppers' first-party data to drive advertising revenue. They are creating media experiences around their content assets utilizing their first-party data to curate and monetize their audiences. First-party data is also increasingly valuable in the absence of third-party identifiers.
 Budgets Shift to Retail Media: Retail Media budgets come from shopper and trade marketing budgets. Brands are taking advantage of this surge in ecommerce and accelerating the shift of their trade marketing budgets to online to address consumers at the digital point of sales, recreating in-store experiences on digital shelves. Retail Media budgets also include performance marketing dollars, and full-funnel Retail Media strategies attract brand marketing budgets as well.
 Brands, Retailers and Publishers Increasingly Depend on AdTech Partners: Changes in online identity make the environment more complex for both marketers and media owners around addressability and measurement. These changes require brands and retailers to better leverage AdTech providers to solve these problems and continue to drive performance for them. The ability for media owners, retailers, brands and agencies to identify users, create and monetize commerce audiences, and drive sales and customer loyalty, today relies on having the right technology partner, able to activate the right data in an efficient way and measure the results in a transparent way across channels.

 Addressable Market
 Starting with Retail Media, we estimate that our serviceable available market (excluding Amazon and China), or SAM, will reach $42 billion in advertising spend by 2025. We also estimate that our serviceable available market for the broader Commerce Media opportunity is expected to reach $110 billion in advertising spend by 2025.
 When including Amazon and China, the Total Addressable Market, or TAM, for Commerce Media is expected to reach $290 billion in advertising spend by 2025.2

 Criteo's Transformation and the Commerce Media Platform
 Since 2018, and accelerating since 2020, Criteo has deeply transformed itself and is now a multi-solution Commerce Media platform provider.
 The Criteo Commerce Media Platform is the only unified platform that directly connects advertisers with retailers and publishers on the open internet. We offer marketer and media owner clients a single platform for first-party data-based marketing and monetization, that provides a holistic suite of solutions, powered by AI technology and activates the world's largest set of commerce data.

 Our technology is optimized to drive trusted and impactful business outcomes efficiently and effectively for our brand, retailer and media owner clients. These include, for example, driving engagement for our clients' brand, shop, app, products and services, driving product sales, driving app installs and consumer visits, driving product consideration from targeted commerce audiences, or driving advertising revenue for media owners and retailers by monetizing their data and audiences with consumer brands.

 Our Solutions

 On the demand side, our goal is to maximize returns for advertisers by delivering impactful advertising to the right consumer across the entire shopping journey:
 • Commerce Max is a Commerce self-service Demand Side Platform ("DSP") used by brands, agencies and retailers, enabling media planning and buying on retailer and open internet inventories, all with closed-loop product-level conversion measurement.
 • Commerce Growth is a powerful, self-service performance marketing tool used by Direct-to-Consumer brands and their agencies to acquire and retain customers.

 On the supply side, we enable media owners to earn more revenue by enriching and activating their first-party data and inventory:
 • Commerce Yield is a suite of monetization solutions giving retailers and marketplaces full control to achieve maximum monetization of their digital assets through inventory and data management, packaging, and in-depth insights.
 • Commerce Grid is a Commerce Supply Side Platform ("SSP") for media owners and access from agencies through the DSP of their choice.

 Our Segments

 Criteo reports its business results as three operating and reportable segments: Marketing Solutions, Retail Media and Iponweb.

 Marketing Solutions are available through Commerce Growth to help advertisers achieve their customer acquisition and retention goals.

 Examples of potential business outcomes driven by Criteo Marketing Solutions include:
 • Discovery: creating and building brand awareness for a client's existing or new product or service, by targeting relevant high-quality consumer audiences showing intent for that particular product or service and reaching these audiences, for example, through online video ads and through Connected TV channels;
 • Choice: driving visits from new prospects on the website of our clients, or driving installations of our clients' apps by new consumers, by engaging such commerce audiences online (either on the web, in apps or on connected TV), with personalized ads offering products or services tailored to their predicted interest;
 • Purchase: driving sales for commerce clients by engaging consumers online, with personalized ads offering products or services for which they have already expressed shopping intent; or driving more sales from existing customers of our commerce clients, by accurately targeting and re-engaging these existing customers online with personalized ads offering new products or services that they have not yet purchased nor been exposed to.

 Our clients have access to an integrated self-service client interface that reduces unnecessary complexity and cost associated with manual processes of having to use multiple DSPs and sources of inventory supply.

 We also offer a managed-service approach to our larger clients, providing deep business intelligence and analytics services. Our teams of advisers aid our larger clients in setting goals for, extracting insights from, and evaluating trends and performance of their various advertising campaigns with us across multiple marketing goals, sources of inventory, advertising channels and formats, and the multiple digital devices that consumers may use.

 In Marketing Solutions, our Commerce Audiences solutions are focused on attracting more customers for our marketer clients and growing their existing customer relationships, leveraging our AI engine to engage commerce audiences with the right ad for each opportunity:
 • Increase awareness and interest in a brand, product, or services;
 • Attract new consumers to an online and/or offline store;
 • Generate leads from consumers who are in market for a brand, product or services;
 • Get more shoppers and grow sales on an online and/or offline store; and
 • Encourage consumers who purchased in the past to make additional purchases.

 For Criteo Marketing Solutions, we typically purchase inventory programmatically on a CPM basis from our direct publisher partners and Real-Time Bidding (RTB) platforms, through standard terms and conditions for the purchase of advertising inventory. This means that inventory purchased for Criteo Marketing Solutions is paid to the publisher irrespective of whether the user engages, in whatever form, with the advertisement delivered on that publisher's digital property. Pursuant to such arrangements, we purchase impressions for users that Criteo recognizes on these publishers' digital properties.

 Retail Media assists retailers in generating high-margin advertising revenues from brands and agencies looking to address multiple marketing goals with strong ROAS, and to drive sales for themselves, by monetizing their audiences through personalized ads, either on their own digital store (also called "onsite") or on media owner properties on the open Internet (also called "offsite").

 Examples of expected business outcomes driven by Criteo Retail Media include:
 • Generating advertising revenue for retailers on their online store, by providing retailers with self-service access to our technology platform for them to monetize their ad inventory, commerce data, traffic and audiences directly with consumer brands across various marketing goals;
 • Driving sales for consumer brand clients on the site of retailer partners, by connecting consumer brands and retailers and engaging consumers on the retailer's digital property with personalized ads offering specific brand products available on the retailer's digital store and for which consumers have expressed interest; and
 • Driving sales for consumer brand clients on the site of retailer partners, by connecting consumer brands and retailers and engaging consumers outside of the retailer property on the open Internet with personalized ads offering specific brand products available on the retailer's digital store and for which consumers have expressed interest.

 Our retailer and brand customers respectively manage their Retail Media revenues and budgets using a self-service interface. We charge retailers a negotiated supply-side platform fee and sometimes a technology or licensing fee, while brands pay us a negotiated demand-side platform fee. In addition, we may charge brands a managed-service fee and other fees for accessing additional insights.

 On the supply side of Retail media, Criteo's retailer monetization solution suite, Commerce Yield, provides retailers, marketplaces and commerce companies with a complete media tool set. Commerce Yield combines Criteo's former Retail Media Platform with several solutions derived from recent strategic acquisitions, including:
 • Commerce Yield Marketplace: We help monetization officers integrate marketplace tactics and formats.
 • Commerce Yield In-Store: Our in-store monetization technology provides advertisers access to a wide range of offline inventory.
 • Commerce Yield Insights: Our cutting-edge suite of insight and data tools provides digital-shelf insights to support enterprise-level retail media buys.

 On the demand side of Retail Media, Criteo's self-service demand-side platform (DSP), Commerce Max, gives brands and agencies a single point of entry to Retail Media inventory onsite and across premium publishers offsite.
 • Brands and agencies across the globe can use Commerce Max to access data and inventory across multiple retailers and marketplaces, finding valuable audiences on these sites and extending these audiences offsite.
 • This is underpinned by closed-loop measurement, enabling brands and agencies to quickly and efficiently determine the effectiveness of campaigns and optimize accordingly.

 Criteo's supply-side platform (SSP), Commerce Grid, brings additional monetization opportunities. It allows retailers to curate their first party audiences and make them available for access through all DSPs.

 Iponweb 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 third-party AdTech platforms. It mainly includes:
 • Criteo's commerce supply-side platform (SSP), Commerce Grid, which is purpose-built for agencies and publishers looking to efficiently connect media and commerce with programmatic.
 • Criteo's commerce services which provide platform customization for our most strategic enterprise and agency clients, and the BidSwitch media trading marketplace, connecting 140 demand and 130 supply partners, to broaden the distribution of commerce audiences on the open Internet.

 Our Competitive Strengths

 Criteo First-Party Media Network

 Our First-Party Media Network is a key pillar of our addressability strategy and represents the combination of our unique data and media assets. It is the powerful combination of our network of direct relationships with media owners, including retailers, together with our Buyer Index dataset focused on commerce and shoppers that powers Criteo's First-Party Media Network.

 Our First-Party Media Network enables consented data to interoperate across marketers and, media owners to engage addressable consumers on a one-to-one basis. It also acts as our Truth set to predict how commerce audiences behave and how ads will perform and convert in the same way. We believe that the amount of addressability data we operate in environments that are deprived of third-party signals will allow us to remain effective at private, safe consumer engagement, to drive the best outcomes for our clients and to capture increasingly more advertising budgets.

 Our First-Party Media Network won the 2021 Digiday Media Award for best first-party strategy.

 Our Data assets: our first-party data-based Buyer Index

 Our data assets include privacy-safe insights derived from our clients' proprietary commerce data about their own consumers, such as transaction activity on their digital properties, giving us exposure to over $1 trillion in online sales on a combined basis in 2023, representing approximately 35% of the global retail ecommerce sales excluding China3, or $2.7 billion worth of transactions per day on average.

 Through direct integration with our clients' digital properties, we obtain large volumes of consented first-party data, expressed consumer shopping intent and engagement, and transactional data at individual product or service levels, which do not rely on cross-site tracking technologies, such as third-party cookies. The information we collect is anonymized and does not enable us to personally identify any individual consumer.

 Our high quality first-party data assets help fuel the accuracy of our algorithms, which improve with the increasing quantity and quality of the data we obtain from our marketer and media owner customers and partners, as well as insights gained through our own extensive operational history. The combination of marketer data, media owner data and proprietary metadata gives us powerful insights into consumer purchasing habits that we use to price media inventory and create relevant ads to drive user engagement and impactful commerce outcomes for our clients. In addition, we seek to use as much relevant information as possible about the context and intent of a given user, collected from customers and media owner partners, to further refine our prediction accuracy.

 We believe our access to first-party commerce data validates the trust that our clients place in us and differentiates us. Most of our clients typically provide real-time access to the products or services a visitor has viewed, researched, added to their shopping cart, or bought from them, and continuously receive updated information on over 4.2 billion products or services across 3,700 product categories, including pricing, images and descriptions. Many of our clients also provide us with their customers' purchase history data in formats that preserve privacy.

 Over the years, we have built data collectives through data pooling amongst many of our marketer clients and media owner partners. The combination of these data collectives forms Criteo's Buyer Index. For each of these data collectives, we ask our clients to grant us the permission to mutualize a significant portion of their proprietary data in an anonymized way with other clients who also contribute data to this collective data pool. With Criteo's Buyer Index, we have built one of the world's largest and most open data sets focused on shoppers and their commerce activity across retailers and brands, and their activity on media owners' properties.

 The Criteo Buyer Index is comprised of the following data collectives:

 • The Identity Graph allows us to match user identifiers provided by clients and publishers across devices and environments, both online and offline. Our algorithms link user identifiers together when they are deemed to belong to the same user. Examples of user identifiers include: hashed customer logins and hashed emails, first-party and third-party cookies, app identifiers, in addition to linkages such as LiveRamp's RampID. The graph has billions of identifiers, which we believe cover approximately 700 million unique Daily Active Users globally, for whom we collect commerce data in real time. In addition, the Identity Graph allows us to leverage offline CRM data of our clients' physical stores to match it with online user profiles, based on their offline shopping history.

 • The Interest Map collects and organizes consumer intent and purchasing data across our network of commerce clients to build a comprehensive and accurate non-identifying shopper profile for all consumers on whom we have collected data. Our Interest Map applications include the Universal Catalog, which provides category and/or brand enrichment, as well as a unified view of the 4.2 billion products SKUs, across 3,700 product categories, available across the combined catalogs of our 18,000 commerce clients2. Every day, we have exposure to data on close to $3 billion in online sales on average through 82 million buyer journeys. We seek our clients' permission to use their data.

 The design and governance of Criteo's Buyer Index are based on strict and differentiated guiding principles.
 We prioritize openness by facilitating a reciprocal data exchange with our marketer and media owner clients. All contributing parties benefit from the shared dataset through our Commerce Media Platform, gaining access to cross-device user IDs and relevant Key Performance Indicators, enhancing their advertising optimization. Transparency is upheld through clear and permission-based data sharing within our data pools, ensuring mutual benefits for all participants. We maintain high levels of data security and user privacy standards for the data we handle.

 Our data collectives are designed to ensure fairness, ensuring that the value gained by each participant surpasses their individual contribution, irrespective of size.
 Consistent with our data minimization principles, our technologies only rely on categories of data that are strictly necessary for the purpose of our services. This means that the user information we collect relates primarily to purchase intent. In addition, we provide consumers with easy-to-use and easy-to-access mechanisms to control their advertising experience and opt out of receiving targeted ads we deliver. This transparent, consumer-centric, and controllable approach to privacy empowers consumers to make better-informed decisions about our use of their data.
 We also actively encourage our clients and media owner partners to provide transparent and clear information to consumers about our collection and use of data relating to the ads we deliver and monitor.
 Our Media assets: our first-party media integrations and media buying scale
 We provide our marketer clients with extensive real-time access to advertising inventory through direct relationships with thousands of media owner partners, as well as selective supply side partnerships. We define inventory as the combination of desktop web, mobile web, mobile in-app display, including social and native, online video displays, connected TV, and ad inventory on major retail ecommerce properties, including standard banners, native and sponsored product formats.
 Our publisher relationships can give us privileged access to first-party publisher data which allow us to bid on impressions without using third-party cookies or other third-party identifiers.
 Many of our direct publisher partners have granted us preferred access to portions of their inventory because of our ability to effectively monetize that inventory. For example, within Criteo Retail Media, we access inventory and first-party data from ecommerce sites that are generally not available to traditional advertising demand. We believe this inventory and data from ecommerce retailers is particularly valuable for consumer brands looking to advertise their products in a multi-brand retail environment.
 We take a variety of brand safety measures to ensure that the brand equity of our clients is preserved at all possible times. These measures include determining that each publisher's inventory meets our content requirements and those of our clients to ensure that their ads are not shown in inappropriate content categories, such as, for example, adult, violence, harassment or hate speech. In addition, we are an active member of the Coalition for Better Ads, supported by Google, and are compliant with their recommendations for user-friendly advertising formats. Criteo's AI Engine is also integrated with Oracle Contextual Intelligence, a solution providing real-time content review and page-level pre-bid classification to clients across 11 standard brand safety categories. In recognition of our efforts to combat fraud and ensure a brand safe digital ecosystem for our advertisers, Criteo has been independently certified by the Trustworthy Accountability Group for the Certification Against Fraud and the Brand Safety Certification.
 AI at Scale
 AI is core to continuously optimizing the performance of our solutions in ways that deliver effective advertising and highly personalized experiences to consumers. AI is also key to driving operational efficiency across our business.
 The Criteo AI Lab
 The Criteo AI Lab was established in 2018 and is pioneering AI innovation with 140 engineers and researchers who closely collaborate to deploy AI at scale through the Criteo AI Engine, and advance new AI technologies. The Criteo AI Lab is recognized as a center of scientific excellence for its research on Deep Learning, Generative AI, Game theory AI, Information Retrieval and Privacy Preserving Machine Learning.

 The Criteo AI Engine
 The Criteo AI Engine is our software and hardware highly scalable AI infrastructure. It leverages the Buyer Index, with the goal of maximizing consumer engagement to drive impactful business outcomes for clients through the delivery of highly relevant and personalized ads in real time. A wide variety of machine learning and deep models power the Criteo AI Engine to optimize each and every touch point on the advertising journey, all the way from media planning to shopper conversion.
 Lookalikes finder algorithms create and activate audiences built out of shopping insights derived from Criteo unique shopper data. This set of algorithms typically supports Commerce Audiences campaigns to drive new prospects to consider brands, products or services with which they have not yet engaged in the past.
 Recommendation algorithms build on top of our cutting-edge Deep KNN (Deep K-Nearest Neighbour) technology, and determine the specific products or services to include in the ad, based on shopper past interactions, or those shopper lookalikes. Deep KNN is Criteo's proprietary Vector Database technology that processes billions of products from our client product feeds.
 Dynamic Creative Optimization+ (DCO+) algorithms optimize banners layout in real time, on a per impression, per user basis. Our patented Dynamic Creative Optimization+ technology offers unlimited personalization, with up to 17 trillion visual ad variations, without the need to define ad sizes or layouts upfront, while always maintaining the consistency of our clients' brand image.
 Predictive bidding algorithms compute the fair price for each potential ad to show. It does so by predicting a user's engagement with a given ad, while optimizing toward client campaign objectives. User engagement may range from site visits, clicks, conversions, shopping basket value, specific product categories purchased, or even the gross margin of the purchased product or service that our client generates from such purchase.
 Sponsored Product placement algorithms combine recommendation and predictive bidding algorithms to determine which sponsored products to show on our Retail Media client search result pages, in response to a user's search queries.
 Our robust software infrastructure allows us to operate seamlessly at a large scale through our network of approximately 39,000 servers as of the end of 2023. The architecture and processing capabilities of this technology have been designed to match the massive computational needs and complexity of our algorithms in real time. This technology enables data synchronization, storage and analysis across a large-scale distributed computing infrastructure in multiple geographies, as well as fast data collection and retrieval using multi-layered caching infrastructure.
 Our Experimentation platform enables our Research & Development team to continuously tune our Criteo AI Engine via experimentation and A/B tests. For example, in 2023, we performed about 1,250 online A/B tests and over 100,000 offline experiments and tests. We use an online/offline testing platform to improve the capabilities and effectiveness of our prediction models by measuring the correlation of specific parameters with user engagement, usually measured by consumer visits, clicks and conversions, typically in the form of sales.
 Privacy-by-design approach. We have long established and adopted Privacy-by-design as a central element of our technology and product design and development cycles, with a strong commitment to ensuring best practices in privacy, security and safety for consumers and our marketer and media owner customers. Since 2013, we have had a designated Data Privacy Officer along with a team of privacy experts. These experts are part of our R&D and Product organizations, and consider all facets of user privacy for the design of any new technology, solution or feature of the Commerce Media Platform. They also perform ongoing Privacy Impact Assessments to monitor potential risks during the product lifecycle and proactively mitigate those risks. The Data Privacy team delivers company-wide privacy training, enforces our privacy policies and is integral to ensuring that we build the best solutions and services. We regularly review and document our internal privacy policies, amend existing policies as necessary and enforce these policies with our clients, media owner partners and vendors.

 Retail Media.
 Our Retail Media value proposition is unique in the market today. Our offering empowers brands and agencies to find valuable audiences on retailer sites using on-site sponsored and display ads but also extend these audiences off-site, across open internet inventory with unified reporting and closed-loop measurement, including product-level sales attribution. We enable brands, agencies, and multiple retailers to buy and sell retail media using a common platform, thus benefiting from meaningful network effects due to our unique position as the technology supporting a multi-retailer ecosystem, whereas most competitors in the retail media space focus on supporting siloed retailer walled gardens. Brands and their agencies use our platform to access unique inventory at meaningful scale, and retailers get access to brand marketing budgets at a scale they would not be able to access on their own. This creates a network effect where the value for clients only increases as more brand and retailer participants join the ecosystem. In addition, our deep technical integrations with retailers make us instrumental to their digital success and enable us to offer preferred or exclusive inventory to brands and agencies, as well as a superior shopper experience to consumers. We require multi-year commitments and product ads exclusivity as part of our standard retailer services agreements.
 Both our unique inventory access and increasingly deep technical integrations with other advertising technology and reporting platforms provide defensible relationships with brands and agencies. For example, our API partner program embeds our technology into ad platforms that brands and agencies already use to buy search, social, and other large platforms' ad inventory.
 Superior Insights and Measurement. We believe we have superior capabilities for Commerce Insights and measurement. Our technology provides our clients with the unique ability to measure against product sales at the product SKU level. For example, our commerce insights can bring together organic shopping data with paid media metrics for brands.
 Scaled Global Presence. We do business in 109 countries and have a direct operating presence through 29 offices in 17 countries. We have achieved this global presence by replicating and scaling our effective business model across all geographic markets. Large businesses are increasingly seeking global advertising partners able to provide comprehensive offerings that are effective across multiple geographies. We believe we can meet this demand by leveraging our scalable AI technology and global network of relationships and are well positioned to serve our clients in virtually every market in which they seek to drive trusted, impactful and measurable business results and commerce outcomes.

 Strong Financial Model. Our profitable, cash-generative financial model allows us to invest for growth while maintaining healthy profitability. Our company has a sustainable, robust profitability margin. In addition, we manage our expense base in a disciplined way, and we have a clear plan to drive operating leverage from scaling and transitioning to more self-service solutions over time, as well as optimizing our business processes.

 Our Business & Growth Opportunities
 Our mission is to power the world's marketers and media owners with trusted and impactful advertising. We enable our clients' business growth through commerce media, by providing best-in-class marketing and monetization services and driving measurable business outcomes at scale. Our vision is to bring richer experiences to every consumer by supporting a fair and open internet that enables discovery, innovation, and choice – powered by trusted and impactful advertising for the world's marketers and media owners.
 Our overarching priority is to drive sustainable and profitable growth for our business. This involves investing in the fast-growing ecommerce space and broadening our value proposition to cover all commerce media marketing goals as part of our Commerce Media Platform driving measurable business outcomes to our marketer and media owner clients.
 We are further expanding our rapidly growing retailer client base, becoming a platform of choice for agencies and brands and reinforcing our performance advantage.
 As part of our transformation, we intend to continue to leverage our existing assets to diversify and strengthen our business outside of retargeting, continue to build and expand our suite of fast-growing new solutions in Commerce Media, and build further competitive moats around our core assets.

 In fiscal year 2023, new solutions represented more than half of our total business. We are investing in the growth of these new solutions and expect them to represent more than 50% of our overall business in 2024.
 We continue to invest in building the world's leading Commerce Media Ecosystem with notable wins and valuable expansions across our partner network. Our ecosystem is a critical part of Criteo's moat and the unique value we provide to clients.
 • E-Commerce Platforms – Criteo became the first open web marketing platform available to merchants using Shopify Audiences to activate their high intent audiences alongside other major advertising platforms like Meta, Google, Pinterest, Snap, and TikTok.
 • Strategics – We have been working to extend Criteo's integrations with major platforms, beyond Shopify, and in Q4 launched our first series of Criteo audiences available in Google's DV360 buying platform.
 •1st party Data – We drove significant scale in receiving first-party customer records from clients with major CDP partners like Adobe, Klaviyo, Amperity as well as extending our partnership with data specialists like LiveRamp and Oracle.
 • Measurement & Verification – Criteo is the first platform to make Integral Ad Science's measurement technology available seamlessly to all retailers globally, supporting increased monetization from brands that rely on this standard being available.
 • Innovation – We signed a new integration to deliver in-store media with leading digital screen provider SES-Imagotag.
 • Addressability – We added four new data partnerships to our Commerce Grid supply-side platform including AirGrid by MiQ, Anonymized and Oracle's Blue Kai data, which will provide our supply-side curation business with additional dimensions for creating deals leverage by partners such as Dentsu UK. All of the partners provide solutions that are protected from the upcoming changes related to access to third-party cookies in Chrome.
 • API Accessibility – We have the largest global independent API program and expanded to 13 partners including SaaS providers, in house agency technology, and in house brand direct technology, such as Skai and Flywheel. We provide our retailers and brand clients the ability to utilize their platform of choice to drive the greatest outcomes for their business. We also continue to expand our partnerships into more regional markets including EMEA and APAC.

 We continue to have an active M&A pipeline, with a critical assessment on technologies and businesses that have the potential to accelerate our Commerce Media Platform strategy by enhancing, complementing or expanding our strategic capabilities, primarily through technology and broadening our Commerce Media capabilities across all channels. Key criteria for acquisitions include demonstrated revenue traction and a proven value proposition for clients and partners and ease of integration. We believe our entrepreneurial culture, growth opportunity, global scale, financial profile, strong brand and market position enable us to be an attractive acquirer.

 Drive Technology and Operations Excellence. We intend to continue to invest in growing our business, while driving productivity and efficiency gains through organization simplification and operational excellence across the company and maintaining healthy profitability. We believe these investments will feed the long-term sustainable growth of Criteo. Driving operational excellence through the company to self-fund for our investments involves increasing automation and the scalability of our operations. We also leverage cutting-edge technology to streamline processes and enhance operational efficiency
 Infrastructure

 Our ability to execute depends on our highly sophisticated global technology software and hardware infrastructure. As of December 31, 2023, we manage our global infrastructure of servers through a global network of data centers. Our global infrastructure is divided into three geographic areas: Americas, Asia-Pacific and EMEA, and our services are delivered through one or more data centers that support each particular area. Within large areas, the data centers are strategically placed to be close to our clients, publishers and users.
 This provides the benefit of minimizing the impact of network latency within a particular geographic area, especially for time-constrained services such as RTB.

 In addition, we replicate data across multiple data centers to maximize availability and performance. We also generally seek to distribute workload across multiple locations to avoid overloads in our systems and increase reliability through redundancy. In addition, we consider sustainability factors as we evaluate our infrastructure footprint, including prioritizing resource efficiency and clean energy to operate sustainable data centers.

 As part of our growth strategy, some of our products rely on major public cloud providers. Performance, response time and reach are driving how we manage cloud capacity.

 We use multiple-layered security controls to protect Criteo AI Engine and our data assets, including hardware- and software-based access controls for our source code and production systems, segregated networks for different components of our production systems and centralized production systems management.
 Our Clients

 On the demand side for commerce media activation, our diversified client base consists of more than 2,600 established brands and agencies, and more than 15,400 performance marketers, primarily in the retail, travel and classifieds verticals, and including some of the largest and most sophisticated commerce companies in the world.

 On the supply side for commerce media monetization, we power the Retail Media Networks of approximately 220 retailers, as media owners. We also partner with approximately 75% of the top 100 ComScore publishers in our largest markets.

 As of December 31, 2023, we had a total of approximately 18,000 clients.4 In 2023, approximately 49% of our client relationships were held directly with the client and the remaining 51% with advertising agencies or other third-parties on the Criteo Marketing Solutions side of the business, whereas 30% of our Criteo Retail Media revenue comes from agencies.

 In 2023 and 2022, our largest client represented 2.1%, and 1.9% of our revenue, respectively, and in 2023 and 2022, our largest 10 clients represented 12.3% and 9.8% of our revenue in the aggregate, respectively.

 There is no group of clients under common control or clients that are affiliates of each other constituting an aggregate amount equal to 10% or more of our consolidated revenues, the loss of which would have a material adverse effect on Criteo.

 Our clients are serviced through a combination of direct and indirect approaches, including through brand agencies for large clients, and performance agencies and resellers for midmarket clients.
 Research and Development

 We invest substantial resources in research and development to maintain our leading position in Commerce Media. Aside from the walled garden platforms, we have one of the largest R&D teams in the AdTech industry and our Criteo AI Lab pioneering innovations in computational advertising. Our engineering group is primarily located in research and development centers in France, Germany, Cyprus, Armenia, Canada and in the U.S. We expect to continue to expand our technological capabilities in the future and to invest significantly in continued research and development and new solutions. We had 1,021 employees primarily engaged in Research and Development and Product as of December 31, 2023. Research and development expenses, including expenses related to the Product group, totaled $242.3 million, $187.6 million and $151.8 million for 2023, 2022 and 2021, respectively.
 Intellectual Property
 Our intellectual property rights are a key component of our success. We rely on a combination of patent, trademark, copyright and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish, maintain and protect our proprietary rights. We generally require employees, consultants, clients, publishers, suppliers and partners to execute confidentiality agreements with us that restrict the disclosure of our intellectual property. We also generally require our employees and consultants to execute invention assignment agreements with us that protect our intellectual property rights.

 4 In the first quarter of 2023, we streamlined our client count methodology which is now based on unique billing accounts while the previous methodology included clients from whom Criteo has received a signed contract or an insertion order during the previous 12 months. The new methodology led to the consolidation of some clients accounts but does not change the underlying activity or the overall trends.

 Intellectual property laws, together with our efforts to protect our proprietary rights, provide only limited protection, and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed or misappropriated. The laws of certain countries do not protect proprietary rights to the same extent as the laws of France and the U.S. and, therefore, in certain jurisdictions, we may be unable to protect our proprietary technology.
 Agreements with our employees and consultants may also be breached, and we may not have adequate remedies to address any breach. Further, to the extent that our employees or consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights to know-how and inventions relating thereto or resulting therefrom. Finally, our trade secrets may otherwise become known or be independently discovered by competitors and unauthorized parties may attempt to copy aspects of the Criteo Commerce Media Platform or obtain and use information that we regard as proprietary.
 As of December 31, 2023, we held 30 patents issued by the U.S. Patent and Trademark Office and various foreign counterparts, and had filed three non-provisional patent applications in the U.S. and Europe. We also own and use registered and unregistered trademarks on or in connection with our products and services in numerous jurisdictions. In addition, we have also registered numerous internet domain names.
 Our industry is characterized by the existence of patents and occasional claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the technology industry have extensive patent portfolios. From time to time, third parties, including certain of these leading companies, have asserted and may assert patent, copyright, trademark and other intellectual property rights against us, our clients or our publishers. Litigation and associated expenses may be necessary to enforce our proprietary rights.

 Privacy, Data Protection and Content Control

 Legal and Regulatory

 Privacy and data protection laws play a significant role in our business. The regulatory environment for the collection and use of consumer data by advertising networks, advertisers and publishers is frequently evolving in the U.S., Europe and elsewhere. The U.S. and foreign governments have enacted, considered or are considering legislation or regulations that could significantly restrict industry participants' ability to collect, augment, analyze, use and share personal data, such as by regulating the level of consumer notice and consent required before a company can utilize cookies or other tracking technologies.

 In the U.S., at both the federal and state level, there are laws that govern activities such as the collection and use of data by companies like us. At the federal level, online advertising activities in the U.S. have primarily been subject to regulation by the Federal Trade Commission, or the FTC, which has regularly relied upon Section 5 of the Federal Trade Commission Act, or Section 5, to enforce against unfair and deceptive trade practices, including alleged violations of consumer privacy interests. Various states have also enacted legislation that governs these practices. The U.S. privacy law framework may be subject to significant evolutions in the near future both at a federal and at a state level. At a federal level, lawmakers are considering the possibility of adopting a federal privacy law and a draft bill was published in this regard in 2022 ("American Data Privacy and Protection Act"). In 2018, the State of California adopted the CCPA, which went into effect on January 1, 2020. The CCPA establishes a privacy framework for covered businesses by, among other requirements, creating an expanded definition of personal information, establishing new data privacy rights for consumers in the State of California, creating new notice obligations and new limits on the sale of personal information, and creating a statutory damages framework for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices to prevent data breaches. We and partners in our industry have been required to comply with these requirements since January 1, 2020, when the CCPA became effective. In November 2020, the voters in California passed the California Privacy Rights Act ("CPRA"), which both amends and expands the scope of the CCPA. The CPRA, which became effective on January 1, 2023, created additional privacy rights and protections for California consumers with respect to their personal information and additional obligations on businesses. We cannot predict the full effect of these laws and regulations on our business, but adapting our business to comply with them could involve substantial resources and expense, and may cause us to divert resources from other aspects of our business, all of which may adversely affect our business.

 Other states in the U.S. are quickly adopting state enacted privacy laws. Virginia, Colorado and more recently, Connecticut and Utah have passed consumer and privacy laws that differ slightly from the CCPA and CPRA. If other states follow suit, it could lead to a varied and complex regulatory landscape, which could result in material costs.

 In addition, the Criteo Commerce Media Platform reaches users throughout the world, including in Europe, Australia, Canada, South America and Asia-Pacific. As a result, some of our activities may also be subject to the laws of foreign jurisdictions. In particular, data protection laws in Europe can be more restrictive regarding the collection and use of data than those in U.S. jurisdictions.

 In the European Union (the "EU"), the two main pillars of the data protection legal framework are the Directive on Privacy and Electronic Communications (the "E-Privacy Directive") and GDPR. The E-Privacy Directive directs EU member states to ensure that accessing information on an Internet user's computer, such as through a cookie and other similar technologies, is allowed only if the Internet user has been informed about such access and given his or her consent. The Court of Justice of the EU clarified that such consent must be reflected by an affirmative act of the user, and European regulators are increasingly agitating for more robust forms of consent. These developments result in ending reliance on implied consent mechanisms that have been used to meet requirements of the E-Privacy Directive in some markets. A replacement for the E-Privacy Directive is still under discussion by EU member states to align the E-Privacy Directive to GDPR and force a harmonized approach across EU member states. It is possible that the proposed e-privacy regulation could further raise the bar for the use of cookies. However, the advancement of the legislative process for the adoption of the e-privacy regulation remains quite uncertain.

 Under GDPR, data protection authorities have the power to impose administrative fines of up to a maximum of 20 million or 4% of the data controller's or data processor's global turnover from the preceding financial year, whichever is higher.

 On October 1, 2020, the French data protection authority (the Commission Nationale de l'Informatique et des Libert s, or the "CNIL") issued the final version of its guidelines on the use of cookies and other trackers and its final recommendations on modalities for obtaining users' consent to store or read non-essential cookies and similar technologies on their devices. The recommendations provide that, when required, consent must be indicated by a clear and positive action of the data subject, such as by clicking on an "accept all" button on the first layer of the consent management platform.

 The CNIL also noted that it should be as easy to refuse consent to the use of cookies as it is to accept consent, and an equivalent to the "refuse all" button should be present on the first layer of the consent management platform. Further, the ability to withdraw consent must be readily available at all times.

 As we continue to expand into other foreign jurisdictions, we may be subject to additional laws and regulations that may affect how we conduct business.

 Self-Regulation
 In addition to complying with extensive government regulations, we voluntarily and actively participate in several trade associations and industry self-regulatory groups that promulgate best practices or codes of conduct relating to targeted advertising. For example, the Internet Advertising Bureau EU & US, the Network Advertising Initiative, the European Digital Advertising Alliance and the Digital Advertising Alliance have developed and implemented guidance for companies to provide notice and choice to users regarding targeted advertising.

 We also provide consumers with notice about our use of cookies and our collection and use of data in connection with the delivery of targeted advertising, and allow them to withdraw consent or opt out from the use of such data for the delivery of targeted advertising. In an effort to harmonize the industry's approach to internet-based advertising, these programs facilitate a user's ability to disable services of integrated providers, but also educate users on the potential benefits of online advertising, including access to free content and display of more relevant advertisements to them. The rules and policies of the self-regulatory programs that we participate in are updated from time to time and may impose additional restrictions upon us in the future.

 Criteo became one of the first companies to broadly include an "Ad Choices" link in all the advertisements we deliver, which gives users access to clear, transparent, detailed and user-friendly information about personalized advertisements and the data practices associated with the advertisements they receive. In addition, we provide consumers with an easy-to-use and easy-to-access mechanism to control their advertising experience and withdraw consent or opt out of receiving targeted advertisements we deliver.

 We believe that this transparent consumer-centric approach to privacy empowers consumers to make better-informed decisions about our use of their data. We also require our clients and publishers to provide information to consumers about our collection and use of data relating to the advertisements we deliver and monitor.

 Content Control and Brand Safety
 Criteo strives to maintain a trusted advertising ecosystem aligned with the marketing goals and the brand requirements of our marketers and media owners alike. We have rigorous supply partner guidelines in place, and we take a large variety of internal and external brand safety measures to ensure that the brand equity of our clients is protected. These measures include our partnership with industry recognized and MRC-accredited services from Oracle Advertising on web and Pixalate on app.
 To protect our clients against invalid traffic (IVT), we have built advanced engine detection and filtration systems that will discard invalid bid requests, impressions and clicks, and we do not bill advertisers for the invalid traffic. We also leverage industry compliant blocklists from the Interactive Advertising Bureau (IAB) and Trustworthy Action Group (TAG) to filter out known sources of invalid traffic and we partner with industry recognized and MRC accredited service Pixalate to supplement our pre-bid and post-bid detection and filtration capabilities of IVT.
 We are recognized for trust & safety and have been certified by the Trustworthy Accountability Group for Certification Against Fraud (CAF) and Brand Safety Certification (BSC) through an independent audit.

 Government Regulation
 Further to the laws and regulations governing privacy and data protection described above, we are subject to numerous domestic and foreign laws and regulations covering a wide variety of subject matters. New laws and regulations (or new interpretations of existing laws and regulations) may also impact our business. The costs of compliance with these laws and regulations are high and are likely to increase in the future and any failure on our part to comply with these laws may subject us to significant liabilities and other penalties. For additional information regarding a recent investigation into the Company's compliance with GDPR, please refer to Refer to Note 20, Commitments and Contingencies, in our audited consolidated financial statements included elsewhere in this Form 10-K.

 Competition
 We compete in the commerce media market and in the broader market for digital marketing and media monetization, primarily through Display Advertising. Our market is complex, rapidly evolving, highly competitive, still fragmented and yet rapidly consolidating. We face significant competition in this market, which we expect to intensify in the future, partially as a result of potential new entrants in our market, including but not limited to large well-established internet publishers and players, in particular as we continue to expand the breadth of the Criteo Commerce Media Platform. We currently compete with large, well-established companies, such as Amazon, Meta Platforms, Google, and Microsoft, pure play Demand-Side Platforms ("DSPs"), such as The Trade Desk or Google's DV360, pure play Supply-Side Platforms ("SSPs") such as Magnite, PubMatic or Google Ad Manager, and pure play retail SSPs such as Microsoft's PromoteIQ or Publicis' CitrusAd, that focus on monetizing retailers' media, as well as smaller, privately held companies. Potential competition could emerge from large enterprise marketing platforms, like Adobe Systems Inc. ("Adobe"), Oracle Corporation ("Oracle") and Salesforce.com, Inc. ("Salesforce"), or public and private companies specialized in the Marketing Technology ("MarTech") space. In addition, web browsers, and desktop and mobile operating systems developed by large software companies like Google and Apple Inc. ("Apple") can have a significant influence and impact on the way we operate.

 We believe the principal competitive factors in our industry include:
 • access to granular commerce data on a large scale;
 • technology-based ability to activate data, in particular commerce data, for multiple digital marketing and media monetization goals, along the entire consumer journey;
 • technology-based ability to generate advertisers' desired business outcomes, including, but not limited to, high return on advertising spend at scale;
 • relevance and breadth of solutions to address numerous digital marketing and media monetization goals;
 • breadth and depth of consumer reach, including in all environments and devices across the open Internet;
 • marketer and publisher control over the objectives, parameters and performance of their advertising campaigns through modular, flexible and easy-to-use tools and services available on a self-service interface;
 • measurability of the advertising spend performance, based on clear and transparent measurement metrics;
 • completeness and effectiveness of solutions across digital devices, commerce and advertising environments, platforms and operating systems, advertising channels and publisher environments;
 • transparency of pricing models, aligning with the value propositions provided to marketers;
 • openness, transparency, security and fairness of data sharing and data management practices;
 • client trust;
 • global presence;
 • client service and detailed, transparent client reporting available on a self-service basis;
 • commitment to data protection and user privacy; and
 • ease of use.
 We believe that we are well positioned in commerce media with respect to all of these factors and expect to continue to capture an increasing share of digital marketing and media monetization budgets worldwide.

 Seasonality
 Our client base consists primarily of companies in the Retail, Travel and Classifieds industries. In the digital Retail industry and the consumer brand verticals in particular, many businesses devote the largest portion of their advertising spend to the fourth quarter of the calendar year, to coincide with increased holiday spending by consumers. As a result, the concentration of advertising spend in the fourth quarter of the calendar year may be particularly pronounced. Our Retail clients typically conduct fewer advertising campaigns in the first and second quarters than they do in other quarters, while our Travel clients typically increase their travel campaigns in the first and third quarters and conduct fewer advertising campaigns in the second quarter. For Iponweb, the first and second quarters are seasonally low quarters in terms of Contribution ex-TAC, adjusted EBITDA and cash contribution, while the fourth quarter is the strongest quarter. As a result, our revenue tends to be seasonal in nature. If the seasonal fluctuations become more pronounced, our operating cash flows could fluctuate materially from period to period.

 Employees and Human Capital Management
 We have a demonstrated history of commitment to the well-being and success of our workforce, and our company is driven by our core values of "open, together and impactful".
 As of December 31, 2023, we had 3,563 employees. Our employees employed by French entities (971 employees) are covered by a collective bargaining agreement and are represented by employees through a Social and Economic Committee (Work Council) affiliated to a trade union. As part of the Social and Economic Committee, five sub-committees have been appointed: Health & Safety Committee, Economic Committee, Gender Equality Committee, Training Committee and a Housing Committee. We consider labor relations to be good and have not experienced any work stoppages, slowdowns or other serious labor problems that have materially impeded our business operations.
 Our Board, with assistance from our Compensation Committee, has oversight of and periodically reviews the Company's strategies, initiatives and programs with respect to the Company's culture, talent recruitment, development and retention and employee engagement.

 Talent Acquisition & Development
 Attracting and retaining top talent is a key objective at Criteo. We are committed to offering an environment in which employees are ensured equal job opportunities and have a chance for advancement. Our compelling employee value proposition, attractive compensation packages and vibrant culture are instrumental in our ability to attract and retain talent.
 Additionally, we strive to provide exceptional training opportunities and development programs for our employees. In 2023, approximately 30,000 training hours were delivered to our employees. To assess and improve employee retention and engagement, we periodically survey employees, and take action to address areas of employee concern. In 2023, we carried out 3 employee surveys, soliciting feedback on a wide range of topics including well-being, flexibility, and inclusion.

 Diversity, Equity & Inclusion
 As a global technology company, we believe that a diverse and inclusive culture is the cornerstone for driving creative collaboration and sustainable change across the industry. We are proud that our employees can be themselves at work and we value diversity in the workforce; as of December 31, 2023, 41% of our employees are women. As stated in our Diversity, Equity and Inclusion policy, our mission is to sustain our focus on equity, and building stronger diversity through how we hire, develop, reward, and retain all talent at Criteo. We empower our employees to impact the industry, promoting diversity, equity, and inclusion in everything we do, delivering richer experiences for all. We are proud to have gender pay parity. Our efforts to foster a diverse and inclusive workplace are led by a dedicated Diversity, Equity and Inclusion leadership team who partner through the business and leverage our seven active Employees Resource Groups ("ERGs") who engage with employees, support allyship and sponsorship to encourage community, networking and safe spaces for all diverse groups throughout Criteo. In 2023, 41% of our employees were involved in at least one of our seven ERGs.

 This work extends to our efforts to strengthen our inclusive culture and drive sustainable efforts that impact our environment and societal interests throughout and beyond Criteo.
 Health, Safety and Wellness
 Employee health, safety and wellness is a priority for Criteo. We devote time and effort across all of our locations to provide positive working conditions, work-life balance and a healthy office environment for our employees. We recognize and support employees with their work life integration and believe that flexibility is an essential element to remain engaged, efficient, and productive. We also believe in the importance of employee contribution and results, rather than focusing on where work is being completed. We foster a dynamic environment where employees are empowered to reach their highest potential.
 Total Rewards
 We are focused on offering competitive compensation and comprehensive benefit packages designed to meet the needs of our employees and reward their efforts and contributions. We seek coherence and fairness in total compensation with reference to external market comparisons, internal equity, and the relationship between management and non-management compensation. Our total compensation packages include base pay, performance-based incentives, long-term incentives such as equity awards, retirement plans, healthcare and other insurance benefits, paid time off, paid family leave, employee assistance and well-being programs among many others.

 Risks Related to Our Business and Industry

 If we fail to innovate, enhance our brand, and adapt and respond effectively to rapidly changing technology, our offerings may become less competitive or obsolete. Our investments in new solutions and technologies to address new marketing goals for our clients are inherently risky and may not be successful.

 Our industry and business are subject to rapid and frequent changes in technology, evolving client needs and the frequent introduction by our competitors of new and enhanced offerings. Our future success will depend on our ability to continuously enhance and improve our offerings to meet client needs, build our brand, scale our technology capabilities, add functionality to and improve the performance of the Criteo Commerce Media Platform, and address technological and industry advancements. If we are unable to enhance our solutions to meet market demand in a timely manner, we may not be able to maintain our existing clients or attract new clients, and our solutions may become less competitive or obsolete. Furthermore, brand promotion activities may not yield increased revenue sufficient to offset expenses or any increased revenue at all.

 Our investments in our Commerce Media Platform and new technologies are inherently risky and may not be successful. Addressing broader marketing and monetization goals, particularly customer acquisition and brand awareness, is relatively new to us, and we have had to invest substantial resources to adapt our model, pricing and organization to support this expansion. It also implies investing in new advertising channels where we do not have a long or established track record of competing successfully. If we are not successful in expanding our solutions along broader marketing goals, our results of operations could be adversely affected. Furthermore, we believe that the importance of brand recognition will increase as competition in our market increases.

 The market in which we participate is intensely competitive, and we may not be able to compete successfully with our current or future competitors.

 The market for digital advertising solutions, including specifically retail media, is highly competitive and rapidly changing, as market participants develop new technologies and offer multiple new products and services aimed at facilitating and/or capturing advertising spend. With the introduction of new technologies and the influx of new entrants to the market, including large established companies, smaller companies that we do not yet know about, or companies that do not yet exist, we expect competition to persist and intensify in the future, which could harm our ability to increase sales and maintain our profitability, including if competition increases pricing pressure.

 Large and established internet and technology companies may have the power and capital to significantly change the very nature of the digital advertising marketplaces in ways that could materially disadvantage us. Some of these companies could leverage their positions to make changes to their web browsers, mobile operating systems, platforms, exchanges, networks or other solutions or services that could be significantly harmful to our business and results of operations. Some of these companies also have significantly larger resources and capital than we do, and in many cases have advantageous competitive positions in popular products and services such as Amazon Advertising, Google Search, YouTube, Chrome, Meta Platforms, and Apple Search Ads, which they can use to their advantage. Furthermore, our competitors have invested substantial resources and capital in innovation, which could lead to technological advancements that change the competitive dynamics of our business in ways that we may not be able to predict.

 In addition to competing for advertising spend, we compete with many companies for advertising inventory, some of whom also operate their own advertising networks or exchanges from which we buy advertising inventory.
 As more companies compete for advertising impressions on advertising exchange platforms and other platforms that aggregate supply of advertising inventory, advertising inventory may become competitive and expensive, which may adversely affect our ability to acquire a consistent supply of advertising inventory and to deliver advertisements on a profitable basis. Some of the companies that we compete with, either for advertising spend or inventory, may also be our clients or affiliated with our clients or important sources of advertising inventory. Competitive pressure may incentivize such companies to cease to be our clients or cease to provide us with access to their advertising inventory.

 If this were to occur, our ability to place advertisements would be significantly impaired and our results of operations would be adversely affected. Some large retailers, which could include our own clients, may develop retail media advertising technologies in-house, and may move some of their demand to a direct sales model such that they would do some of their own sales. Competition could also hinder the success of new advertising solutions that we offer in the future.

 If any of these risks were to materialize, our ability to compete effectively could be significantly compromised and our results of operations could be harmed. Any of these developments would make it more difficult for us to sell our offerings and could result in increased pricing pressure, reduced fees and gross margins, increased sales and marketing expense and/or the loss of market share.

 Our success depends on our ability to implement our business transformation and achieve our global business strategies.

 Our business has recently undergone, and continues to undergo, a significant transformation, partially in response to major changes in the advertising technology industry driven by, but not limited to, regulations such as GDPR and restrictions on data collection and use, including those implemented by large technology companies. The components of our transformation include diversification of our services as we shift away from third-party cookies, focus on growth and investment, and certain organization adjustments and cost optimization opportunities. Our future performance and growth depend on the success of this transformation and our new business strategies, including our management team's ability to successfully implement them.

 Our ongoing transformation has resulted, and may continue to result, in changes to business priorities and operations, capital allocation priorities, operational and organizational structure, and increased demands on management. Such changes could result in short-term and one-time costs, lost clients, reduced sales volume, higher than expected restructuring costs, retention issues and loss of key personnel, workforce productivity challenges and other negative impacts on our business. We may also become subject to the risks of workforce dissatisfaction, negative publicity and business disruption in connection with these initiatives.

 Completion of our business transformation may take longer than anticipated, and, once implemented, we may not realize, in full or in part, the anticipated benefits or the realization of such benefits may be delayed. The failure to realize benefits or savings, which may be due to our inability to execute plans, delays in the implementation of the transformation and our product roadmap, global or local economic conditions, competition, changes in the advertising technology industry and the other risks described herein, could have a material adverse effect on our business, financial condition and results of operations, as well as the trading price of our securities.

 The failure by Criteo AI Engine to accurately predict engagement by users and maintain the quality of our client and publisher content could result in significant costs to us, lost revenue and diminished business opportunities.

 The effective delivery of certain of our digital advertising solutions depends on the ability of Criteo AI Engine to predict the likelihood that a consumer will engage with any given internet display advertisement with a sufficient degree of accuracy so that our clients can achieve desirable returns on their advertising spend. We historically charged our clients primarily based on a cost-per-click pricing model, and our clients only paid us when a user engaged with the advertisement, usually by clicking on it. Although we have evolved our pricing models alongside our broader suite of solutions, a large part of our revenue is still generated through cost-per-click pricing models or an equivalent.

 Many of our agreements with clients are open-ended and often do not include a spending minimum. Similarly, our contracts with publishers generally do not include long-term obligations requiring them to make their inventory available to us over long periods of time. Therefore, we need to continuously deliver satisfactory results for our clients and publishers to maintain and increase revenue, which depends partly on the optimal functioning of Criteo AI Engine.

 In addition, we have experienced significant growth in the amount and complexity of data processed by Criteo AI Engine and the number of advertising impressions we deliver. As the amount of data and number of variables processed by Criteo AI Engine increase, and the calculations that the algorithms must compute become increasingly complex, the risk of errors in the type of data collected, stored, generated or accessed also increases.

 Our client's satisfaction also depends on our ability to keep advertisements from being placed in unlawful or inappropriate content, or content that is not permitted under the terms of the applicable agreements with clients. While this depends in part on the optimal functioning of the Criteo AI Engine, as more of our clients use our self-service tools with less intervention by us, it could become more challenging to train and support such clients to use such tools and to prevent inappropriate or unlawful advertisements from being shown. Fraudulent or malicious activity, including non-human traffic, could also impair the proper functioning of Criteo AI Engine. For example, the use of bots or other automated or manual mechanisms to generate fraudulent clicks or misattribute clicks on advertisements we deliver could overstate the performance of our advertising. Due to the higher cost per 1,000 impressions paid for online video and Connected TV advertisements, the risk of fraudulent traffic may increase as we increase our purchasing of online video and Connected TV inventory.

 If we were to experience significant errors, defects, or fraudulent or malicious activity in Criteo AI Engine, including such that we are unable to keep our clients' advertisements from being placed in unlawful or inappropriate content, our solution could be impaired or stop working altogether, which could significantly impair our ability to purchase any advertising inventory and generate any revenue until the errors, defects or fraudulent or malicious activity were detected and corrected. Other negative consequences from experiencing such issues in Criteo AI Engine could include:
 • a loss of clients and publishers or a decrease in inventory purchased by clients;
 • fewer consumer visits to our client websites or mobile applications;
 • faulty inventory purchase decisions, resulting in lower profitability per impression, up to an including negative margins, for which we may need to bear the cost;
 • lower return on advertising spend for our clients;
 • lower price for the advertising inventory we can offer to publishers;
 • delivery of advertisements that are less relevant or irrelevant to users, resulting in lower click-through rates or conversion rates;
 • being blocked by internet service providers or regulators;
 • refusals to pay, demands for refunds, loss of confidence, termination of campaigns or withdrawal of future business and potential liability for damages or regulatory inquiries or lawsuits; and
 • negative publicity or harm to our reputation.

 As a result, the failure by Criteo AI Engine to accurately predict engagement of users and maintain the quality of our client and publisher content and to continue to do so over time could result in significant costs to us, lost revenue and diminished business opportunities.

 Third parties may implement technical restrictions that impede our access to data and revenue opportunities upon which we rely, which could materially impact our business and results of operations.

 A substantial portion of the data we rely on comes from our publisher partners and other third parties, including advertising exchange platforms (including supply-side platforms, or "SSPs", such as Google's Ad Manager) and retailers. Similarly, we rely on our publisher partners, advertising exchange platforms and other third parties, such as retailers, for opportunities to serve advertisements through which we generate our revenue. Our ability to successfully leverage such data and successfully generate revenue from such opportunities could be impacted by restrictions imposed by or on our publisher partners or other third parties, including restrictions on our ability to use or read cookies or other tracking features or our ability to use real-time bidding networks or other bidding networks.

 For example, in light of GDPR, some SSPs imposed restrictions on our ability to bid on opportunities to serve ads. Third-party publishers are responsible under GDPR for gathering necessary user consents and indicating to SSPs that Criteo has been approved by the applicable users. As part of their efforts to comply with their understanding of the requirements of GDPR, which are subject to interpretation, certain SSPs that run advertising exchanges have required actions from such third-party publishers with respect to such consents that appear stricter than regulations require. Similarly, SSPs and other relevant third parties may take similar actions in response to any new legislation or regulatory developments or interpretations in the future, in response to perceived user preferences, or for other reasons.

 If third parties on which we rely for data or opportunities to serve advertisements impose similar restrictions or are not able to comply with restrictions imposed by other ecosystem participants, we may lose the ability to access data, bid on opportunities, or purchase digital ad space, which could have a substantial impact on our revenue.

 Our ability to generate revenue depends on our collection of significant amounts of data from various sources, which may be restricted by consumer choice, clients, publishers, browsers or other software, changes in technology, and new developments in laws, regulations and industry standards.

 Our ability to optimize the delivery of internet advertisements for our clients depends on our ability to successfully leverage data, including data that we collect from our clients, data we receive from our publisher partners and third parties, and data from our own operating history. Using cookies and non-cookie based mechanisms, such as hashed emails, hashed customer log-ins, mobile phone numbers or mobile advertising identifiers, we collect information about the interactions of users with our clients' and publishers' digital properties (including, for example, information about the placement of advertisements and users' shopping or other interactions with our clients' websites or advertisements). Our ability to successfully leverage such data depends on our continued ability to access and use such data, which could be restricted by a number of factors, including consumer choices, restrictions imposed by counterparties (such as clients, supply sources and publishers, who may also compete with us for advertising spend and inventory), web browser developers or other software developers, changes in technology, including changes in web browser technology, increased visibility of consent or "do not track" mechanisms or "ad-blocking" software, the emergence of new opt-out signals such as "Global Privacy Control" and "Global Privacy Platform", and new developments in, or new interpretations of, laws, regulations and industry standards. These types of restrictions could materially impair the results of our operations.

 Web browser developers, such as Apple, Mozilla Foundation, Microsoft or Google, have implemented or may implement changes in browser or device functionality that impair our ability to understand the preferences of consumers, including by limiting the use of third-party cookies or other tracking technologies or data indicating or predicting consumer preferences. Today, four major web browsers — Apple's Safari, Mozilla's Firefox, Microsoft's Edge, and Samsung Internet Browser — block third-party cookies by default. Internet users can also delete cookies from their computers and mobile devices at any time. Google has announced plans to phase out support for third-party cookies in Chrome, with a one-percent deprecation of third-party cookies for Chrome users globally in the first half of 2024 and the entire phase out planned for the second half of 2024, subject to the approval of the UK Competition and Market Authority who is ensuring that Google provides an acceptable advertising targeting solution to the market to replace third-party cookies, such as Google's Privacy Sandbox initiative. Google's Privacy Sandbox would limit improper tracking through third-party cookies and replace it with certain application programming interfaces ("APIs") that would allow advertisers to receive aggregated data without using such third-party cookies. While we are one of the largest scaled partners in the Privacy Sandbox as it is being developed and tested, if the Privacy Sandbox is adopted, it could require us to make changes to how we collect information on consumer preferences. Google controls more than 60% of the browser market and has an even more dominant position in the digital advertising market. These web browser developers have significant resources at their disposal and command substantial market share, and any restrictions they impose could foreclose our ability to understand the preferences of a substantial number of consumers.
 Although we are actively in the process of moving our business away from third-party cookies towards relying more on first-party data-based and other identifiers, if we are blocked from serving advertisements to a significant portion of internet users, our business could suffer and our results of operations could be harmed.

 Similarly, Internet users are increasingly able to download free or paid "ad-blocking" software, including on mobile devices, which prevent third-party cookies from being stored on a user's computer and block advertisements from being displayed to such user. In addition, Google has introduced ad blocking software in its Chrome browser that blocks certain ads based on quality standards established under a multi-stakeholder coalition. If such a feature inadvertently or mistakenly blocks ads that are not within the established blocking standards, or if such capabilities become widely adopted and the advertising technology industry does not collaboratively develop alternative technologies, our business could be harmed. The Interactive Advertising Bureau and Digital Advertising Alliance have also developed frameworks that allow users to opt out of the "sale" of their personal information under the CCPA, in ways that stop or severely limit the ability to show targeted ads.

 In addition, search engines and other service providers that explicitly do not allow the tracking of data may be growing in popularity. If a significant number of web browser users switch to advertising-free services or platforms, our business could be materially impacted. Further, mobile devices allow users to opt out of the use of mobile device IDs for targeted advertising.

 For in-app advertising, data regarding interactions between users and devices are tracked mostly through stable, pseudonymous mobile device identifiers that are built into the device operating system with privacy controls that allow users to express a preference with respect to data collection for advertising, including to disable the identifier. These identifiers and privacy controls are defined by the developers of the mobile platforms and could be changed by the mobile platforms in a way that may negatively impact our business. For example, Apple now requires user opt-in before permitting access to Apple's unique identifier, or IDFA. This shift from enabling user opt-out to an opt-in requirement has had, and is likely to continue to have, a substantial impact on the mobile advertising ecosystem and could harm our growth in this channel.

 User privacy features of other channels of programmatic advertising, such as Connected TV or over-the-top video, are still developing. Technical or policy changes, including regulation or industry self-regulation, could harm our growth in those channels.

 The data we gather is important to the continued development and success of Criteo Shopper Graph, which is a key element of the Criteo Commerce Media Platform. If too few of our clients provide us with the permission to share their data or if our clients choose to stop sharing their data, or if regulatory or other factors inhibit or restrict us from maintaining the data collectives underlying Criteo Shopper Graph, the value of Criteo Shopper Graph could be materially diminished, which could impact the performance of our products and materially impact our business.

 In addition, our ability to collect and use data may be restricted or prevented by a number of other factors, including:
 • the failure of our, or our clients', network, hardware, or software systems;
 • our inability to grow our client and publisher base in new industry verticals and geographic markets in order to obtain the critical mass of data necessary for Criteo AI Engine to perform optimally in such new industry verticals or geographic markets;
 • malicious traffic (such as non-human traffic) that introduces "noise" in the information that we collect from clients and publishers; and
 • interruptions, failures or defects in our data collection, mining, analysis and storage systems, including due to our reliance on external third-party providers for cloud computing services and data center hosting services, in a competitive market subject to close legal and regulatory scrutiny.

 Any of the above-described limitations could also harm our business and adversely impact our future results of operations.

 Our international operations and expansion expose us to several risks.

 As of December 31, 2023, we had a direct operating presence through 29 offices located in 17 countries and did business in 109 countries. Our current global operations and future initiatives involve a variety of risks, including:
 • operational and execution risk, including localization of the product interface and systems, translation into foreign languages, adaptation for local practices, adequate coordination to onboard local clients and publishers, difficulty of maintaining our corporate culture, challenges inherent to hiring and efficiently managing employees over large geographic distances, and the increasing complexity of the organizational structure required to support expansion and operations into multiple geographies and regulatory systems;
 • insufficient, or insufficiently coordinated, demand for and supply of advertising inventory in specific geographic markets processed through Criteo AI Engine, which could impair its ability to accurately predict user engagement in that market;
 • compliance with (and liability for failure to comply with) applicable local laws and regulations, including, among other things, laws and regulations with respect to data protection and user privacy, data use, tax and withholding, labor regulations, anti-corruption, environment, consumer protection, economic sanctions, public health crises (including the outbreak of contagious disease and pandemics), spam and content, and artificial intelligence, which laws and regulations may be inconsistent across jurisdictions;
 • intensity of local competition for digital advertising budgets and internet advertising inventory;
 • changes in a specific country's or region's political or economic conditions;
 • risks related to tariffs and trade barriers, pricing structure, payment and currency, including aligning our pricing model and payment terms with local norms, higher levels of credit risk and payment fraud, difficulties in invoicing and collecting in foreign currencies and associated foreign currency exposure, restrictions on foreign ownership and investments, and difficulties in repatriating or transferring funds from or converting currencies; and

 • limited or unfavorable intellectual property protection;

 Additionally, operating in international markets also requires significant management attention and financial resources. We cannot be certain that the investment and additional resources required in establishing operations in other countries will produce desired levels of revenue or profitability.

 Because our functional currency is the euro, while our reporting currency is the U.S. dollar, we face exposure to fluctuations in foreign currency exchange rates. Foreign currency exchange risk exposure also arises from intra-company transactions and financing with subsidiaries that have a functional currency different than the euro. While we are engaging in hedging transactions to minimize the impact of uncertainty in future exchange rates on intra-company transactions and financing, we may not hedge all of our foreign currency exchange rate risk. In addition, hedging transactions carry their own risks and costs, and could expose us to additional risks that could harm our financial condition and operating results.

 Regulatory, legislative or self-regulatory developments regarding internet or online matters could adversely affect our ability to conduct our business.

 Governmental authorities around the world have enacted, considered or are considering legislation or regulations that could significantly restrict our ability to collect, process, use, transfer and pool data collected from and about consumers and devices. Trade associations and industry self-regulatory groups have also promulgated best practices and other industry standards relating to targeted advertising.

 In the European Union (the "EU"), the two main pillars of the data protection legal framework are the Directive on Privacy and Electronic Communications ("E-Privacy Directive") and the General Data Protection Regulation ("GDPR"). The E-Privacy Directive directs EU member states to ensure that accessing information on an Internet user's computer, such as through a cookie and other similar technologies, is allowed only if the Internet user has been informed about such access and given his or her consent. The Court of Justice of the EU clarified that such consent must be reflected by an affirmative act of the user in line with the requirements applicable to consent under GDPR. These developments result in ending reliance on implied consent mechanisms used to meet requirements of the E-Privacy Directive in some markets. A replacement by an E-Privacy Regulation for the E-Privacy Directive is still under discussion by EU member states to align the E-Privacy Directive to GDPR and force a harmonized approach across EU member states. The proposed E-Privacy Regulation could further impede the use of cookies. However, the advancement of the legislative process for the adoption of the E-Privacy Regulation remains quite uncertain.

 Under GDPR, data protection authorities have the power to impose administrative fines of up to a maximum of 20 million or 4% of the data controller's or data processor's total worldwide turnover from the preceding financial year. Similar sanctions would be applicable under the E-Privacy Regulation to cookie consent.

 Further, on October 1, 2020, the French data protection authority (the Commission Nationale de l'Informatique et des Libert s, or the "CNIL") issued the final version of its guidelines on the use of cookies and other trackers and its final recommendations on modalities for obtaining users' consent to store or read non-essential cookies and similar technologies on their devices. The recommendations provide that, when required, consent must be indicated by a clear and positive action of the data subject, such as by clicking on an "accept all" button on the first layer of the consent management platform. The CNIL also noted that it should be as easy to refuse consent to the use of cookies as it is to accept consent, and an equivalent "refuse all" button should be present on the first layer of the consent management platform. Further, the ability to withdraw consent must be always readily available. Companies had until March 2021 to ensure compliance with these guidelines. The CNIL has launched investigations and sanctioned companies for lack of compliance with its guidelines on cookies. The European Center for Digital Rights ("NOYB") has also filed several complaints with data protection authorities for failure to comply with GDPR requirements.

 In January 2020, the CNIL opened a formal investigation into Criteo. In June 2023, the CNIL issued its decision, which retained alleged GDPR violations but reduced the financial sanction against Criteo from the original amount of 60.0 million ($65.0 million) to 40.0 million ($44.0 million). Criteo made the required sanction payment in 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 Conseil d'Etat. Refer to Note 20. Commitments and Contingencies for more information.

 In 2018, the State of California adopted the California Consumer Privacy Act of 2018 (the "CCPA")., which went into effect on January 1, 2020, and requires covered companies to, among other things, provide new disclosures to California consumers and afford such consumers new abilities to opt out of the sale of their personal information. In November 2020, voters in California passed the California Privacy Rights Act ("CPRA"), which both amends and expands the scope of the CCPA. The CPRA, which became effective on January 1, 2023, created additional privacy rights and protections for California consumers with respect to their person information and additional obligations on businesses. We cannot predict the full effect of these laws and regulations on our business, but adapting our business to comply with them could involve substantial resources and expense, and may cause us to divert resources from other aspects of our business, all of which may adversely affect our business.

 In addition, other states in the U.S. are quickly adopting state enacted privacy laws. Virginia, Colorado and more recently, Connecticut and Utah have passed consumer and privacy laws that differ slightly from the CCPA and CPRA. If other states follow suit, it could lead to a varied and complex regulatory landscape, which could result in material costs.

 Clarifications of and changes to these existing and proposed laws, regulations, judicial interpretations and industry standards can be costly to comply with, and we may be unable to pass along those costs to our clients in the form of increased fees, which may negatively affect our operating results. Such changes can also delay or impede the development of new solutions, result in negative publicity and reputational harm, require significant management time and attention, increase our risk of non-compliance and subject us to claims or other remedies, including fines or demands that we modify or cease existing business practices, such as our ability to charge per click or the scope of clicks for which we charge. Additionally, any perception of our practices or solutions as an invasion of privacy, whether such practices or solutions are consistent with current or future regulations and industry practices, may subject us to public criticism, private class actions, reputational harm or claims by regulators, which could disrupt our business and expose us to increased liability. Finally, our legal and financial exposure often depends in part on our clients' or other third parties' adherence to and compliance with privacy laws and regulations and their use of our services in ways consistent with visitors' expectations. If our clients fail to adhere to our contracts in this regard, or a court or governmental agency determines that we have not adequately, accurately or completely described our own solutions, services and data collection, use and sharing practices in our own disclosures to consumers, then we and our clients and publisher partners may be subject to potentially adverse publicity, damages and investigation or other regulatory activity in connection with our privacy practices or those of our clients.

 Additionally, legislative and regulatory action is emerging in the areas of artificial intelligence ("AI"), which given our long history using and innovating through AI with the Criteo AI Engine, could increase costs or restrict opportunity. Compliance with existing, expanding, or new laws and regulations regarding AI may involve significant costs or require changes in products or business practices that could adversely affect our results of operations. Additionally, depending on how the final text of the EU's Artificial Intelligence Act will regulate the AI supply chain, our ability to innovate may be affected if we cannot have access to foundation models and general-purpose AI in the same manner as our non-EU competitors.

 We may not be able to effectively integrate the businesses we acquire, which may adversely affect our ability to achieve our growth and business objectives.

 We explore, on an ongoing basis, potential acquisitions of additional businesses, products, solutions, technologies or teams. If we identify an appropriate acquisition candidate, we may not be successful in negotiating the terms and/or financing of the acquisition, and our due diligence may fail to identify all of the problems, liabilities or other shortcomings or challenges of an acquired business, product, solution or technology, including issues related to intellectual property, product quality or architecture, employees or clients, cybersecurity, regulatory compliance, including tax compliance, practices or revenue recognition or other accounting practices.

 Any acquisition or investment may require us to use significant amounts of cash, incur debt, issue potentially dilutive equity securities or incur contingent liabilities or amortization of expenses, or impairment of goodwill and/or purchased long-lived assets, and restructuring charges, any of which could harm our financial condition or results. The Company has incurred and will incur significant transaction and acquisition-related costs in connection with its acquisitions, including legal, accounting, financial advisory, regulatory and other expenses. The payment of such transaction costs could adversely effect on our financial condition, results of operations or cash flows. In addition, acquisitions involve numerous risks, any of which could harm our business, including:
 • difficulties in integrating the operations, technologies, services and personnel of acquired businesses, especially if those businesses operate outside of our core competency and market;

 • the need to integrate operations across different geographies, cultures and languages and to address the economic, currency, political and regulatory risks associated with specific countries;
 • ineffectiveness, lack of scalability, or incompatibility of acquired technologies or services;
 • potential of integration of cybersecurity issues or flaws in acquired technologies;
 • potential loss of key employees of acquired businesses;
 • inability to maintain the key business relationships and the reputation of acquired businesses or products;
 • failure to successfully further develop the acquired technology to recoup our investment;
 • diverting management's attention from other business concerns;
 • liability or litigation for activities of the acquired business, including claims from terminated employees, clients, former shareholders or other third parties;
 • implementation or remediation of controls, practices, procedures and policies at acquired businesses, including the costs necessary to establish and maintain effective internal controls; and
 • increased fixed costs without corresponding offsetting growth.

 If we are unable to successfully integrate or leverage the commercial relationships of the businesses we have acquired or any business, product, solution, technology or team we acquire in the future, our business and results of operations could suffer, and we may not be able to achieve our business and growth objectives.

 We have substantial client concentration in certain local markets and solutions, with a limited number of clients accounting for a substantial portion of our revenues in those areas.

 Although our overall customer base is well-diversified, with our largest 10 clients representing 12.3% of our revenue in the aggregate in 2023, in certain of our local markets and specific solutions we derive a substantial portion of revenues from a limited number of clients. We cannot predict the future level of demand for our services and products generated by these clients, and revenues from these clients may fluctuate. Further, some of our contracts with these clients may permit them to terminate or reduce use of our products at any time (subject to notice and certain other provisions). If we fail to retain any of these clients or any of these clients terminate or reduce use of our products, if not replaced by new clients and an increase in business from existing clients, our revenues within local markets or specific solutions may be negatively impacted.

 We operate in a rapidly evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful. Our historical growth rates may not be indicative of our future growth, and we may have difficulty sustaining profitability.

 We operate in a rapidly evolving industry. Our ability to forecast our future operating results is subject to several uncertainties, including our ability to plan for and model future growth in both our business and the digital advertising market. We are subject to risks and uncertainties frequently experienced by growing companies in rapidly evolving industries, including challenges in forecasting accuracy, determining appropriate nature and levels of investments, predicting adequate future headcount, assessing appropriate returns on investments, achieving market acceptance of our existing and future offerings, managing client implementations and developing new solutions. If our assumptions regarding these uncertainties, which we regularly use and update to plan our business, are incorrect or change in reaction to changes in our markets, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations and our business could suffer.
 You should not consider our revenue growth in past periods to be indicative of our future performance. In future periods, our revenue could decline or grow more slowly than we expect. We believe the growth of our revenue depends on a number of factors, including our ability to:

 • attract new clients, and retain and expand our relationships with existing clients;
 • maintain the breadth of our media owner network and attract new publishers and media owners, including large retailers, publishers of web content, mobile applications and video and social games, in order to grow the volume and breadth of advertising inventory available to us;
 • broaden our solutions portfolio to include additional marketing and monetization goals for commerce companies and consumer brands across the open Internet, including web, apps and stores;
 • adapt our offering to meet evolving needs of businesses, including to address market trends such as (i) the continued migration of consumers from desktop to mobile and from websites to mobile applications, (ii) the increasing percentage of sales that involve multiple digital devices, (iii) the increasing retailer adoption of retail

 media monetization solutions, (iv) the growing adoption by consumers of "ad-blocking" software on web browsers on desktop and/or on mobile devices and use or consumption by consumers of advertising-free services, (v) changes in the marketplace for and supply of advertising inventory,
 (vi) changes in the overall ecosystem resulting in signal loss and (vii) changes in consumer acceptance of tracking technologies for targeted or behavioral advertising purposes;
 • maintain and increase our access to data necessary for the performance of Criteo AI Engine;
 • continuously improve the algorithms underlying Criteo AI Engine and apply state-of-the-art machine learning approaches and hardware; and
 • continue to adapt to a changing regulatory landscape governing data use, data protection, privacy matters and artificial intelligence.

 We also anticipate continuing to invest in our business to increase the scale of our Commerce Media Platform and attract more media spend. We cannot be certain that this strategy will be successful or result in increased liquidity or long-term value for our shareholders.

 We derive a significant portion of our revenue from companies in the retail, travel and classified industries, and any downturn in these industries or any changes in regulations affecting these industries could harm our business.

 A significant portion of our revenue is derived from companies in the Retail, Travel and Classifieds industries. For example, in 2023 and 2022, 77.7% and 78.5%, respectively, of our combined revenue for Criteo Marketing Solutions was derived from advertisements placed for Retail commerce businesses. Any downturn or increased competitive pressure in any of our core industries, such as retailer bankruptcies due to poor economic conditions, or other industries we may target in the future, may cause our clients to reduce their spending with us, or delay or cancel their advertising campaigns with us.

 Our future success will depend in part on our ability to expand into new industry verticals.

 As we market our offering to a wider group of consumer brands and companies outside of our historical key industry verticals of retail, travel and classifieds, among others, we will need to adapt our solutions and effectively market our value to businesses in these new industry verticals. Our successful expansion into new industry verticals will depend on various factors, including our ability to:
 • accumulate sufficient data sets relevant for those industry verticals to ensure that Criteo AI Engine has sufficient quantity and quality of information to deliver efficient and effective internet display advertisements applicable to the relevant industry;
 • design solutions that are attractive to businesses in such verticals;
 • work with clients in new industry verticals through the advertising agencies that manage their advertising budgets;
 • hire personnel with relevant industry vertical experience to lead sales and product teams;
 • provide high returns on advertising spend in such industries and maintain such high returns on advertising spend at scale; and
 • transparently measure the performance of such advertising spend based on clear, measurable metrics.

 If we are unable to successfully adapt our offering to appeal to businesses in industries other than our core verticals, or are unable to effectively market such solutions to businesses in such industries, we may not be able to achieve our growth or business objectives. Further, as we expand our client base and offering into new industry verticals, we may be unable to maintain our current client retention rates.

 As we expand the market for our solutions, we may become more dependent on advertising agencies as intermediaries, which may adversely affect our ability to attract and retain business.

 As we market our solutions, we may increasingly need advertising agencies to work with us in assisting businesses in planning and purchasing for broader marketing goals. In the last quarter of 2023, 30% of Criteo Retail Media's gross media spend and 32% of Criteo Marketing Solutions' gross media spend relied on advertising agencies.

 Overall, we believe that accessing broader advertising budgets by partnering with advertising agencies represents a significant incremental business opportunity for us, though it also may involve significant risks.

 For example, if we have an unsuccessful engagement with an advertising agency on a particular advertising campaign, we risk losing the ability to work not only for the client for whom the campaign was run, but also for other clients represented by that agency.
 Further, if our business evolves such that we are increasingly working through advertising agency intermediaries, we would have less of a direct relationship with our clients. This may drive our clients to attribute the value we provide to the advertising agency rather than to us, further limiting our ability to develop long-term relationships directly with our clients. Additionally, our clients may move from one advertising agency to another, and, accordingly, even if we have a positive relationship with an advertising agency, we may lose the underlying client's business when the client switches to a new agency.

 The presence of advertising agencies as intermediaries between us and our clients thus creates a challenge to building our own brand awareness and maintaining an affinity with our clients, who are the ultimate sources of our revenue. In the event we were to become more dependent on advertising agencies as intermediaries, this may adversely affect our ability to attract and retain business. In addition, an increased dependency on advertising agencies may harm our results of operations, because of the increased agency fees we may be required to pay and/or because of longer payment terms from agencies.

 Our future success will depend in part on our ability to expand into new advertising channels.

 We define an advertising channel as a specific advertisement medium to engage with a user or a consumer for which we currently purchase inventory through a specific source. We started delivering elements of our offering through internet display advertisements in desktop browsers. Since then, we have expanded into mobile in-browser and in-app, native display, including on social media platforms, and online video inventory.

 We may decide to broaden the spectrum of our advertising channels further, including into Social, Connected TV and Digital Out of Home, if we believe that doing so would significantly increase the value we can offer to clients. However, any future attempts to enter new advertising channels may not be successful.

 Our success in expanding into any additional advertising channels will depend on various factors, including our ability to:
 • identify additional advertising channels where our solutions could perform;
 • accumulate sufficient data sets relevant for those advertising channels to ensure that Criteo AI Engine has a sufficient quantity and quality of information to deliver relevant personalized advertisements;
 • adapt our solutions to additional advertising channels and effectively market such channels to our existing and prospective clients;
 • integrate newly developed or acquired advertising channels into our pricing and measurement models, with a clear and measurable performance attribution mechanism that works across all channels, and is consistent with our privacy standards;
 • achieve our client's expected levels of performance through the new advertising channels;
 • identify and establish acceptable business arrangements with inventory partners and platforms to access inventory of sufficient quality and quantity for these new advertising channels;
 • maintain our gross margin at a consistent level upon entering one or more additional advertising channels;
 • compete with new market participants active in these additional advertising channels; and
 • attract and retain key personnel with relevant technology and product expertise to lead the integration of additional advertising channels onto our platform, and sales and operations teams to sell and integrate additional advertising channels.

 Any decrease in the use of current advertising channels, whether due to clients losing confidence in the value or effectiveness of such channels, regulatory or technology restrictions or if we are unable to successfully adapt our solutions to additional advertising channels and effectively market such offerings to our existing and prospective clients, or if we are unable to maintain our pricing and measurement models in these additional advertising channels, may prevent us from achieving our growth or business objectives.

 We experience fluctuations in our results of operations due to a number of factors, which make our future results difficult to predict and could cause our operating results to fall below expectations or our guidance.

 Our quarterly and annual results of operations fluctuate due to a variety of factors, many of which are outside of our control. Fluctuations in our results of operations could cause our performance to fall below the expectations of analysts and investors, and adversely affect the price of our ADSs. You should not rely on our past results as an indication of our future performance. Factors that may affect our quarterly results of operations include:
 • the nature of our clients' products or services, including the seasonal nature of our clients' advertising spending;
 • lengthy implementation cycles resulting in substantial expenses incurred without any guarantee of revenue generation;
 • demand for our offering and the size, scope and timing of digital advertising campaigns;
 • for certain parts of our business, the relative lack of long-term agreements with our clients and publishers;
 • client and publisher retention rates;
 • market acceptance of our offering and future solutions and services (i) in current and new industry verticals, (ii) in new geographic markets, (iii) in new advertising channels, or (iv) for broader marketing goals;
 • the timing of large expenditures related to expansion into new solutions, new geographic markets, new industry verticals, acquisitions and/or capital projects;
 • the timing of adding support for new digital devices, platforms and operating systems;
 • the amount of inventory purchased through direct relationships with publishers versus internet advertising exchanges or networks;
 • our clients' budgeting cycles;
 • changes in the competitive dynamics of our industry, including consolidation among competitors;
 • consumers' response to our clients' advertisements, to online advertising in general and to tracking technologies for targeted or behavioral advertising purposes;
 • our ability to control costs, including our operating expenses;
 • network outages, errors in our technology or security breaches and any associated expense and collateral effects;
 • foreign currency exchange rate fluctuations, as some of our foreign sales and costs are denominated in their local currencies;
 • failure to successfully manage or integrate any acquisitions; and
 • general economic and political conditions in our domestic and international markets, including public health crises (such as the outbreak of contagious disease or pandemics) and geopolitical conflicts.

 As a result, we may have a limited ability to forecast future revenue and expenses, and our results of operations may from time to time fall below our estimates or the expectations of public market analysts and investors.

 We face intense competition for employee talent, and if we do not retain and continue to attract highly skilled talent or retain our senior management team and other key employees, we may not be able to achieve our business objectives.

 Our future success depends on our ability to continue to attract, hire, retain and motivate highly skilled employees, particularly AI experts, software engineers, product managers and other employees with the technical skills that enable us to deliver effective advertising solutions. Competition for diverse, experienced and highly skilled employees in our industry is intense, in particular in the fields of AI and data science, and we expect certain of our key competitors, who are larger than us and have access to more substantial resources, to pursue top talent on a global basis.

 Our future success also depends on the continued service of our senior management team. As a global team heading a global company, our management team must operate and collaborate across multiple physical locations and geographies, which can make coordinated management more challenging. Business transformation periods, changes in leadership and changes due to business reorganization may result in uncertainty, impact business performance and strategies, and retention of key personnel. We may be unable to attract or retain the management and highly skilled personnel who are critical to our success, which could hinder our ability to keep pace with innovation and technological change in our industry or result in harm to our key client and publisher relationships, loss of key information, expertise or proprietary knowledge and unanticipated recruitment and training costs.

 In addition, a flexible remote working environment may present operational, cybersecurity and corporate culture challenges for which we may need to adapt.

 If we are unable to continue to successfully attract and retain highly skilled talent, senior management and maintain our corporate culture, it could adversely affect our ability to compete effectively and execute on our business strategy.

 Risks Related to Data Privacy, Intellectual Property and Cybersecurity

 Our business involves the use, transmission and storage of personal data and confidential information, and the failure to properly safeguard such information could result in significant reputational harm and monetary damages.

 Our business involves the use, storage and transmission of confidential consumer, client and publisher information and personal data, including certain purchaser data, as well as proprietary software and financial, employee and operational information. Security breaches could expose us to unauthorized disclosure of this information, litigation and possible liability, as well as damage to our relationships with our clients and publishers. If our security measures are breached as a result of third-party action, employee or contractor error, malfeasance or otherwise and, as a result, someone obtains unauthorized access to such data, our reputation could be damaged, our business may suffer and we could incur significant liability.

 Our industry is prone to cyber-attacks by third parties seeking unauthorized access to our data or users' data or to disrupt our ability to provide services. As a result of our prominence, the size of our user base, and the volume of personal data on our systems, we believe that we are a particularly attractive target for such breaches and attacks. Any failure to prevent or mitigate security breaches and improper access to or disclosure of our data or user data, trade secrets and intellectual property, or information from marketers, could result in the loss or misuse of such data, which could harm our business and reputation and diminish our competitive position. In addition, computer malware/ransomware, viruses, unauthorized access or system compromises and hacking by sophisticated actors, including potential attacks from nation-state actors, have become more prevalent in our industry. Our products embed open source software. There may be vulnerabilities in open source software that may make our products susceptible to cyberattacks. We rely on cloud storage providers. There may be increased security exposure due to our use of cloud storage. Security incidents have occurred on our systems in the past, and will likely occur on our systems in the future.

 Techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target. As a result, we are unable to anticipate some of these techniques or to implement adequate preventative measures for such techniques. In addition, the perpetrators of such activity often are very sophisticated, and can include foreign governments and other parties with significant resources at their disposal.

 Cyber-attacks continue to constantly evolve in sophistication and volume, and inherently may be difficult to anticipate and detect for long periods of time. Although we have developed systems and processes that are designed to protect data, and to prevent or detect security breaches, such measures have not provided, and cannot be expected to provide, absolute security, and we may incur significant costs in protecting against and remediating cyber-attacks. We may also have to expend considerable resources on determining the nature and extent of such attacks.

 If an actual or perceived security breach occurs, the market perception of our security measures could be harmed, and we could lose both clients and revenue. Any significant violations of data privacy or other security breaches could result in the loss of business, litigation and regulatory investigations and penalties that could damage our reputation and adversely impact our results of operations and financial condition. Moreover, if a high profile security breach occurs with respect to another provider of digital advertising solutions, our clients and potential clients may lose trust in the security of providers of digital advertising in general, and Display Advertising solutions in particular, which could adversely impact our ability to retain existing clients or attract new ones.

 Additionally, third parties may attempt to fraudulently induce employees, consumers, our clients, our publishers or third-party providers into disclosing sensitive information such as user names, passwords or other information in order to gain access to our data, our clients' data or our publishers' data, which could result in significant legal and financial exposure and a loss of confidence in the security of our offering and, ultimately, harm to our future business prospects. A party who is able to compromise the security of our facilities, including our data centers or office facilities, or any device, such as a smartphone or laptop, connected to our systems could misappropriate our, our clients', our publishers' or consumers' proprietary information, or cause interruptions or malfunctions in our operations or those of our clients and/or publishers.

 We have expended significant resources to protect against such threats and to alleviate problems caused by breaches in security and may have to expend additional resources for such purposes in the future.
 Our errors and omissions insurance may be inadequate or may not be available in the future on acceptable terms, or at all. In addition, our policy may not cover any claim against us for loss of data or other indirect or consequential damages and defending a suit, regardless of its merit, could be costly and divert management's attention.

 Our efforts to address undesirable activity on our platform may also increase the risk of retaliatory attacks. As a result, we may suffer significant legal, reputational, or financial exposure, which could adversely affect our business and results of operations.

 Failures in the systems and infrastructure supporting our solutions and operations, including as we scale our offerings, could significantly disrupt our operations and cause us to lose clients.

 In addition to the optimal performance of Criteo AI Engine, our business relies on the continued and uninterrupted performance of our software and hardware infrastructures. We currently place close to five billion advertisements per day and each of those advertisements can be placed in under 100 milliseconds.

 Sustained or repeated system failures of our, or our third-party providers', software or hardware infrastructures (such as massive and sustained data center or cloud service provider outages), which interrupt our ability to deliver advertisements quickly and accurately, our ability to serve and track advertisements, our ability to process consumers' responses to those advertisements or otherwise disrupt our internal operations, could significantly reduce the attractiveness of our offering to clients and publishers, reduce our revenue or otherwise negatively impact our financial situation, impair our reputation and subject us to significant liability.

 Additionally, if, for any reason, our arrangement with one or more data centers or cloud providers is terminated, we could experience difficulties and additional expense in arranging for new facilities and support, particularly given the current competitive nature of the data centers market at a worldwide scale, which involves high demands, low offers and strong pressure from providers to increase prices and diversify their client base. Any steps we take to ensure business continuity and increase the security, reliability and redundancy of our systems supporting the Criteo technology or operations may be expensive and may not be successful in preventing system failures. Similarly, advancements in machine learning approaches and other technology may require us to upgrade or replace essential hardware (such as graphics processing units), which could involve substantial resources and could be difficult to implement.

 In addition, while we seek to maintain excess capacity to facilitate the rapid provision of new client deployments and the expansion of existing client deployments, we may need to increase data center hosting capacity, bandwidth, storage, power or other elements of our system architecture and our infrastructure as our client base and/or our traffic continues to grow. The expansion and improvement of our systems and infrastructure may require us to commit substantial financial, operational and technical resources, with no assurance that the providers will honor such requests or that our business will increase. Our existing systems may not be able to scale up in a manner satisfactory to our existing or prospective clients, and may not be adequately designed with the necessary reliability and redundancy of certain critical portions of our infrastructure to avoid performance delays or outages that could be harmful to our business. Our failure to continuously upgrade or increase the reliability and redundancy of our infrastructure to meet the demands of a growing base of global clients and publishers could adversely affect the functioning and performance of our technology and could in turn affect our results of operations.

 Finally, our systems and the systems of our third-party providers are vulnerable to damage and increased costs from a variety of sources, some of which are outside of our control, including telecommunications failures, natural disasters, terrorism, power outages, a variety of other possible outages affecting data centers, increases in the price of energy needed to power and cool data centers, a decision to close any data center or the facilities of any other third-party provider without adequate notice, and malicious human acts, including hacking, computer viruses, malware/ransomware and other security breaches. Techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target. As a result, we may be unable to anticipate some of these techniques or to implement adequate preventive measures.

 If we are unable to prevent system failures, the functioning and performance of our solutions could suffer, which in turn could interrupt our business and harm our results of operations.

 If we are unable to protect our proprietary information or other intellectual property, our business could be adversely affected.

 Our patents, trademarks, trade secrets, copyrights, and other intellectual property rights are important assets for us. Various events outside of our control pose a threat to our intellectual property rights, as well as to our products, services, and technologies.
 For example, effective intellectual property protection may not be available in every country in which we operate or intend to operate our business. Third parties may knowingly or unknowingly infringe our proprietary rights or challenge proprietary rights held by us, and our pending and future trademark and patent applications may not be approved. Although we seek to obtain patent protection for our innovations, it is possible we may not be able to protect some of these innovations in a sufficient or effective manner. Moreover, we may not have adequate patent or copyright protection for certain innovations that later turn out to be important.
 Furthermore, there is always the possibility, despite our efforts, that the scope of the protection gained will be insufficient or that an issued patent may be deemed invalid or unenforceable.

 Breaches of the security of our information system, our third-party providers' information system or other IT resources could also result in the exposure of our proprietary information. Additionally, our trade secrets may be independently developed by competitors. We cannot be certain that the steps we have taken to protect our trade secrets and proprietary information will prevent unauthorized use or reverse engineering of our trade secrets or proprietary information.

 To protect or enforce our intellectual property rights, we may initiate litigation against third parties. Any lawsuits that we initiate could be expensive, take significant time and divert management's attention from other business concerns. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially valuable. Any increase in the unauthorized use of our intellectual property may adversely affect our business, financial condition and results of operations.

 Our business may suffer if it is alleged or determined that our technology or another aspect of our business infringes the intellectual property rights of others.

 The online and mobile advertising industries are characterized by the existence of large numbers of patents, copyrights, trademarks, trade secrets and other intellectual property and proprietary rights. Our success depends, in part, upon non-infringement of intellectual property rights owned by others and being able to resolve claims of intellectual property infringement or misappropriation without major financial expenditures or adverse consequences. From time to time, we may be the subject of claims that our services, solutions and underlying technology infringe or violate the intellectual property rights of others, particularly as we expand the scope and complexity of our business.

 Regardless of whether claims that we are infringing trademarks, patents or other intellectual property rights have any merit, these claims are time-consuming and costly to evaluate and defend, and the outcome of any litigation is inherently uncertain. Some of our competitors have substantially greater resources than we do and are able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. Claims that we are infringing trademarks, patents or other intellectual property rights could subject us to significant liabilities for monetary damages, interfere with or delay our development, commercialization or provision of our offerings on acceptable terms, harm our reputation or require us to make technology or branding changes to our offerings.

 In addition, we may be exposed to claims that the content contained in advertising campaigns violates the intellectual property or other rights of third parties and although we may have the right of recourse, this may be difficult or costly to enforce. Such claims could be made directly against us or against the advertising agencies we work with, and media networks and exchanges and publishers from whom we purchase advertising inventory.
 Under our agreements with larger partners, including advertising agencies, media networks and exchanges and publishers, we may be required to indemnify such partners against claims with respect to an advertisement we served. We generally require our clients to indemnify us for any damages from any such claims. There can be no assurance, however, that our clients will have the ability to satisfy their indemnification obligations to us, and pursuing any claims for indemnification may be costly or unsuccessful. As a result, we may be required to satisfy our indemnification obligations to advertising agencies, media networks and exchanges and publishers or claims against us with our assets. This result could harm our reputation, business, financial condition and results of operations, and could impact our relationships with advertising agencies, media networks and exchanges, or clients.

 Our inability to use software licensed from third parties, or our use of open source software under license terms that interfere with our proprietary rights, could disrupt our business.

 Our technology platform and internal systems incorporate software licensed from third parties, including some software, known as open source software, which we use without charge. Although we monitor our use of open source software, the terms of many open source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and there is a risk that such licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to provide our technology offering to our clients. In the future, we could be required to seek licenses from third parties in order to continue offering our solutions, which licenses may not be available on terms that are acceptable to us, or at all.

 Alternatively, we may need to re-engineer our offering or discontinue using portions of the functionality provided by our technology. In addition, the terms of open source software licenses may require us to provide software that we develop using such software to others on unfavorable terms, such as by precluding us from charging license fees or by requiring us to disclose our source code. Any such restriction on the use of our own software, or our inability to use open source or third-party software, could result in disruptions to our business or operations, or delays in our development of future offerings or enhancements of our existing platform, which could impair our business.

 Risks Related to Ownership of Our Shares and the ADSs and the Trading of the ADSs
 The market price for the ADSs has been and may continue to be volatile or may decline regardless of our operating performance.

 The trading price of the ADSs has significantly fluctuated, and is likely to continue to fluctuate, substantially. The trading price of the ADSs depends on a number of factors, including those described in this "Risk Factors" section, many of which are beyond our control and may not be related to our operating performance. Since the ADSs were sold at our initial public offering in October 2013 at a price of $31.00 per share, the price per ADS has ranged as low as $5.89 and as high as $60.95 through December 31, 2023. The market price of the ADSs has fluctuated and may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

 • actual or anticipated fluctuations in our revenue and other results of operations;
 • the guidance we may provide to the public, any changes in this guidance or our failure to meet this guidance;
 • investor perception of risks in our industry;
 • failure of securities analysts to initiate or maintain coverage of us and our securities, changes in financial estimates by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;
 • announcements by us, our competitors or large influential technology companies of significant technical innovations or changes, acquisitions, strategic partnerships, joint ventures or capital commitments;
 • changes in operating performance and stock market valuations of advertising technology or other technology companies, or those in our industry in particular;
 • investor sentiment with respect to our competitors, business partners or industry in general;
 • price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;
 • additional ADSs being sold into the market by us or the Company's insiders;
 • media coverage of our business and financial performance;
 • developments in anticipated or new legislation or new or pending lawsuits or regulatory actions;
 • other events or factors, including those resulting from economic recessions, natural disasters or weather events, cybersecurity incidents, pandemics, war, terrorism or other catastrophic events or responses to these events; and
 • any other risks identified in this Form 10-K.

 In addition, stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, shareholders have instituted securities class action litigation following periods of market volatility. Because of the past and the potential future volatility of our stock price, we may become the target of securities litigation in the future.

 If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

 We may need additional capital in the future to meet our financial obligations and to pursue our business objectives. Additional capital may not be available on favorable terms, or at all, which could compromise our ability to meet our financial obligations and grow our business.

 We currently have a senior unsecured revolving credit facility under which we may borrow up to 407 million (or its equivalent in U.S. dollars) for general corporate purposes, including the funding of business combinations (the "General RCF"). Maturity of this facility is in September 2027. While we anticipate that our existing cash and cash equivalents and short-term investments will be sufficient to fund our operations for at least the next 12 months, we intend to continue growing our business, including through retail media, and as such, we cannot assure that we will be able to generate sufficient cash flow from operations or that future borrowings will be available under our General RCF in an amount sufficient to fund, among other things, the capital requirements of retail media, new product development, or our future working capital needs. If we may need to raise additional capital to fund operations and growth in the future or to finance acquisitions and adequate funds are not available on acceptable terms, we may be unable to fund the expansion of our research and development and sales and marketing efforts, the development of new features or enhancements to our products, increase working capital, take advantage of acquisition or other opportunities, or adequately respond to competitive pressures which could seriously harm our business and results of operations.

 Furthermore, if we raise additional funds through the issuance of additional equity securities, shareholders will experience dilution, and the new equity securities could have rights senior to those of our ordinary shares.

 Our business could be negatively impacted by the activities of hedge funds or short sellers.

 There is the risk that we may be subject, from time to time, to challenges arising from the activities of hedge funds, short sellers or similar individuals who may not have the best interests of shareholders or the Company in mind. Reports or other publications prepared and disseminated by such hedge funds or short sellers may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business, and could cause the price of our ADSs or trading volume to decline. Furthermore, responding to such activities could be costly and time-consuming and may be intended to, and may in fact, divert the attention of our board of directors and senior management from the pursuit of our business strategies and adversely affect our business.

 Our credit agreement contains, and future debt agreements may contain, restrictions that may limit our flexibility in operating our business.

 The credit agreement for the General RCF contains, and documents governing our future indebtedness may contain, numerous covenants that limit the discretion of management with respect to certain business matters. These covenants place restrictions on, among other things, our ability and the ability of our subsidiaries to incur or guarantee additional indebtedness, pay dividends, sell certain assets or engage in mergers and acquisitions, and create liens. Our credit agreement also requires, and documents governing our future indebtedness may require, us or our subsidiaries to meet certain financial ratios and tests. To the extent we draw on the General RCF or incur new debt, the debt holders have rights senior to shareholders to make claims on our assets.

 The breach of any of these covenants or noncompliance with any of these financial ratios and tests could result in an event of default under the applicable debt agreement, which, if not cured or waived, could result in acceleration of the related debt and the acceleration of debt under other instruments evidencing indebtedness that may contain cross-acceleration or cross-default provisions.

 We do not currently intend to pay dividends on our securities and, consequently, the ability to achieve a return on your investment will depend on appreciation in the price of the ADSs. In addition, French law may limit the amount of dividends we are able to distribute.

 We have never declared or paid any cash dividends on our ordinary shares and do not currently intend to do so for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth, both organic and inorganic.

 In addition, we have used a portion of our available liquidity to repurchase our shares in the past (such repurchases being limited as per French law in scope (employee incentive purposes or external growth purposes only) and in amount (notably the Company cannot hold more than 10% of its share capital at any time)), and may continue to do so from time to time in the future.

 In addition, to the extent any dividends are paid in the future, under French law, payment of such dividends may subject us to additional taxes, and the determination of whether we have been sufficiently profitable to pay dividends is made on the basis of our statutory financial statements prepared and presented in accordance with accounting principles generally accepted in France. Therefore, we may be more restricted in our ability to declare dividends than companies not based in France. Please see the section entitled "Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities-French Tax Consequences" in Item 5 of Part II in this Form 10-K for further details on such taxes and limitations.

 Finally, exchange rate fluctuations may affect the amount of euros that we are able to distribute, and the amount in U.S. dollars that our shareholders receive upon the payment of cash dividends or other distributions we declare and pay in euros, if any. These factors could harm the value of ADSs, and, in turn, the U.S. dollar proceeds that holders receive from the sale of ADSs.

 Because you are not likely to receive any dividends on your ADSs for the foreseeable future, the success of an investment in ADSs will depend upon any future appreciation in their value. Consequently, investors may need to sell all or part of their holdings of ADSs after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

 Our by-laws and French corporate law contain provisions that may delay or discourage a sale of the Company.

 Provisions contained in our by-laws and the corporate laws of France, the country in which we are incorporated, could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our shareholders. In addition, provisions of our by-laws impose various procedural and other requirements, which could make it more difficult for shareholders to effect certain corporate actions. These provisions include, but are not limited to, the following:
 • our ordinary shares are in registered form only and we must be notified of any transfer of our shares in order for such transfer to be validly registered;
 • under French law, certain investments in any entity governed by a French law relating to certain strategic industries and activities (such as data processing, transmission or storage activities) by individuals or entities not French, not resident in France or controlled by entities not French or not resident in France are subject to prior authorization of the Minister of Economy (see the section entitled "Exchange Controls & Ownership by Non-French Residents" in Item 5 to Part II in this Form 10-K);
 • provisions of French law allowing the owner of 90% of the share capital or voting rights of a public company to force out the minority shareholders following a tender offer made to all shareholders are only applicable to companies listed on a stock exchange of the EU and will therefore not be applicable to us;
 • a merger (i.e., in a French law context, a stock-for-stock exchange following which our Company would be dissolved into the acquiring entity and our shareholders would become shareholders of the acquiring entity) of our Company into a company incorporated outside of the EU would require the unanimous approval of our shareholders;
 • a merger of our Company into a company incorporated in the EU would require the approval of our board of directors as well as a two-thirds majority of the votes held by the shareholders present, represented by proxy or voting by mail at the relevant extraordinary shareholders' meeting;
 • under French law, a cash merger is treated as a share purchase and would require the consent of each participating shareholder; and
 • our shareholders have preferential subscription rights proportionally to their shareholding in our Company on the issuance by us of any additional securities for cash or a set-off of cash debts, which rights may only be waived by the extraordinary general meeting (by a two-thirds majority vote) of our shareholders or on an individual basis by each shareholder.

 You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.

 Holders of ADSs may exercise voting rights with respect to the ordinary shares represented by the ADSs only in accordance with the provisions of the deposit agreement, as amended from time to time. The deposit agreement provides that, upon receipt of notice of any meeting of holders of our ordinary shares, the depositary will fix a record date for the determination of ADS holders who shall be entitled to give instructions for the exercise of voting rights. Upon timely receipt of notice from us, if we so request, the depositary shall distribute to the holders as of the record date (1) the notice of the meeting or solicitation of consent or proxy sent by us and (2) a statement as to the manner in which instructions may be given by the holders.

 You may instruct the depositary of your ADSs to vote the ordinary shares underlying your ADSs. Otherwise, you will not be able to exercise your right to vote, unless you withdraw the ordinary shares underlying the ADSs you hold. However, you may not know about the meeting far enough in advance to withdraw those ordinary shares. If we ask for your instructions, the depositary, upon timely notice from us, will notify you of the upcoming vote and arrange to deliver our voting materials to you. We cannot guarantee you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your ordinary shares or to withdraw your ordinary shares so that you can vote them yourself.

 If the depositary does not receive timely voting instructions from you, it may give a proxy to a person designated by us to vote the ordinary shares underlying your ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote, and there may be nothing you can do if the ordinary shares underlying your ADSs are not voted as you requested.

 Your right as a holder of ADSs to participate in any future preferential subscription rights or to elect to receive dividends in shares may be limited, which may cause dilution to your holdings.

 According to French law, if we issue additional securities for cash, current shareholders will have preferential subscription rights for these securities proportionally to their shareholding in our Company unless they waive those rights at an extraordinary meeting of our shareholders (by a two-thirds majority vote) or individually by each shareholder.

 However, our ADS holders in the U.S. will not be entitled to exercise or sell such rights unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. In addition, the deposit agreement provides that the depositary will not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act or exempted from registration under the Securities Act.

 Further, if we offer holders of our ordinary shares the option to receive dividends in either cash or shares, under the deposit agreement the depositary may require satisfactory assurances from us that extending the offer to holders of ADSs does not require registration of any securities under the Securities Act before making the option available to holders of ADSs. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act.

 Accordingly, ADS holders may be unable to participate in our rights offerings or to elect to receive dividends in shares and may experience dilution in their holdings. In addition, if the depositary is unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably practicable, it will allow the rights to lapse, in which case you will receive no value for these rights.

 You may be subject to limitations on the transfer of your ADSs and the withdrawal of the underlying ordinary shares.

 Your ADSs, which may be evidenced by American Depositary Receipts, are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of your ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or governmental body, or under any provision of the deposit agreement, or for any other reason subject to your right to cancel your ADSs and withdraw the underlying ordinary shares.

 Temporary delays in the cancellation of your ADSs and your withdrawal of the underlying ordinary shares may arise because the depositary has closed its transfer books or we have closed our transfer books, the transfer of ordinary shares is blocked to permit voting at a shareholders' meeting or we are paying a dividend on our ordinary shares.

 In addition, you may not be able to cancel your ADSs and withdraw the underlying ordinary shares when you owe money for fees, taxes and similar charges and when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities.

 U.S. investors may have difficulty enforcing civil liabilities against our Company, directors and senior management.

 Certain of our directors and members of senior management, and those of certain of our subsidiaries, are non-residents of the U.S., and all or a substantial portion of our assets and the assets of such persons are located outside the U.S. As a result, it may not be possible to serve process on such persons or us in the U.S. or to enforce judgments obtained in U.S. courts against them or us based on civil liability provisions of the securities laws of the U.S. Additionally, it may be difficult to assert U.S. securities law claims in actions originally instituted outside of the U.S.

 Foreign courts may refuse to hear a U.S. securities law claim because foreign courts may not be the most appropriate forums in which to bring such a claim. Even if a foreign court agrees to hear a U.S. securities law claim, it may determine that the law of the jurisdiction in which the foreign court resides, and not U.S. law, is applicable to the claim.

 Further, if U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact, which can be a time-consuming and costly process, and procedural rules would still be governed by the law of the jurisdiction in which the foreign court resides. In particular, there is some doubt as to whether French courts would recognize and enforce certain civil liabilities under U.S. securities laws in original actions or judgments of U.S. courts based upon these civil liability provisions. In addition, damages exceeding the actual damages in actions brought in the U.S. or elsewhere, such as punitive damages, may be unenforceable in France.

 The enforceability of any judgment in France will depend on the particular facts of the case as well as the laws and treaties in effect at the time. The U.S. and France do not currently have a treaty providing for recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters; therefore, the recognition and enforcement of any such judgment would be subject to French procedural law and may not be granted.

 The rights of shareholders in companies subject to French corporate law differ in material respects from the rights of shareholders of corporations incorporated in the U.S.

 We are a French company with limited liability. Our corporate affairs are governed by our by-laws and by the laws governing companies incorporated in France. The rights of shareholders and the responsibilities of members of our board of directors are in many ways different from the rights and obligations of shareholders in companies governed by the laws of U.S. jurisdictions.
 For example, in the performance of its duties, our board of directors is required by French law to consider the interests of our Company while taking into consideration its social and environmental challenges, its shareholders, its employees and other stakeholders, rather than solely our shareholders and/or creditors. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a shareholder.

 General Risk Factors

 In periods of macroeconomic and geopolitical uncertainty, businesses may delay or reduce their spending on advertising, which may expose us to the credit risk of some of our clients and adversely affect our business, financial condition, results of operations and/or cash flows.

 Our business depends in part on worldwide economic conditions and on the overall demand for advertising and the economic health of advertisers that benefit from our platform. Global economies, including the U.S. and Europe, are being impacted by adverse economic conditions, including inflation, elevated interest rates, recessions, volatility in credit, equity and foreign exchange markets, bankruptcies and overall uncertainty with respect to the economy.

 These conditions coupled with geopolitical instability, such as the current conflicts in the Middle East and Ukraine, make it difficult for our clients and us to accurately forecast and plan future business activities, and may result in businesses reducing or delaying advertising spending in general and on a solution such as ours.

 Additionally, we are exposed to credit risks due to our financing activities and our evolving client portfolio involving credit risk from varied payment terms, which could result in further exposure if our clients are adversely affected by any such macroeconomic uncertainty. The timing of receipt of payment from our clients may impact our cash flows and working capital.

 If any such macroeconomic conditions remain uncertain, persist, spread or deteriorate further, this could continue to significantly impact, our operating results, financial condition and cash flows.

 If we fail to maintain an effective system of internal controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of the ADSs may, therefore, be adversely impacted.

 As a public company, we are required to maintain internal controls over financial reporting ("ICFR") and to report any material weaknesses in such internal control. In addition, we are required to submit a report by management to the Audit Committee and external auditors on the effectiveness of our ICFR pursuant to Section 404 of the Sarbanes-Oxley Act ("SOX") and our independent registered public accounting firm is required to attest to the effectiveness of our ICFR. If we identify material weaknesses in our ICFR, if we are unable to comply with the requirements of Section 404 of SOX in a timely manner or assert that our ICFR are effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our ICFR when required, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of ADSs may be adversely impacted, and we could become subject to investigations by the stock exchange on which our securities are listed, the SEC, or other regulatory authorities, which could require additional financial and management resources.

 Our failure to maintain certain tax regimes applicable to French technology companies may adversely affect our results of operations.

 As a French technology company, we have benefited from certain tax advantages, including, for example, a reduced tax rate in France on technology royalty income received from global subsidiaries and the French research tax credit (cr dit d'imp t recherche, or "CIR"). The French tax authority may audit these tax incentives and challenge all or part of their benefits. In such a case, we could be liable for additional corporate tax, and penalties and interest related thereto, which could have a significant impact on our results of operations and future cash flows. Furthermore, the tax laws may change, and could remove these incentives in the future or reduce their benefits.

 We are a multinational organization facing increasingly complex tax issues in many jurisdictions, and new taxes or laws, or revised interpretations thereof, that may negatively affect our results of operations.

 As a multinational organization operating in multiple jurisdictions, we are subject to taxation in several jurisdictions around the world with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have a material adverse effect on our liquidity and results of operations. For instance,,we will continue to assess the ongoing impact of Digital Services Taxes ("DST") and we closely monitor the Organization for Economic Co-operation and Development tax reforms of Pillar 1 and Pillar 2 that may remove DST (Pillar 1), or may generate additional taxes (Pillar 2).

 U.S. Holders of our ADSs may suffer adverse tax consequences if we are treated as a "passive foreign investment company" for U.S. federal income tax purposes.

 A non-U.S. corporation will be considered a "passive foreign investment company", or PFIC, for U.S. federal income tax purposes, for any taxable year if either (1) at least 75% of its gross income for such year is passive income or (2) at least 50% of the value of its assets (based on an average of the quarterly values of the assets during such year) is attributable to assets that produce or are held for the production of passive income. Passive income includes, among other things, dividends, interest, certain non-active rents and royalties, net gains from the sale or exchange of property producing such income and net foreign (non-U.S.) currency gains.

 For this purpose, cash and assets readily convertible into cash are generally categorized as passive assets, subject to a limited exception under proposed regulations in respect of working capital held in a non-interest bearing financial account for the present needs of an active trade or business to cover operating expenses reasonably expected to be paid within 90 days. Goodwill and other un-booked intangibles are taken into account and being characterized as either active or passive, as appropriate; for example, our goodwill associated with active business activity is taken into account as a non-passive asset.

 As the value of our assets for purposes of the above-mentioned PFIC asset test will generally be determined by reference to the market value of our ADSs, the determination of whether we will be or become a PFIC will depend in large part upon the market value of our ADSs, which we cannot control.

 Accordingly, fluctuations in the market price of our ADSs may cause us to become a PFIC for the current taxable year or future taxable years. The determination of whether we will be or become a PFIC will also depend, in part, upon the nature of our income and the valuation of our assets, including goodwill, which are subject to change from year to year. Moreover, as we have valued our goodwill based on the market value of our ADSs, a decrease in the price of ADSs may also result in becoming a PFIC. The composition of our income and assets may also be affected by how, and how quickly, we use our liquid assets.

 For purposes of the above-mentioned PFIC tests, we will be treated as if we held our proportionate share of the assets and received directly our proportionate share of the income of any other corporation in which we directly or indirectly own at least 25% (by value) of the shares of such corporation.

 Based on the value and composition of our assets, although not free from doubt, we do not believe we were a PFIC for the taxable year ended December 31, 2023, and we do not anticipate becoming a PFIC in the current taxable year or the foreseeable future.

 The determination of whether we are a PFIC is a fact-intensive determination that must be made on an annual basis applying principles and methodologies that are in some circumstances unclear. Since a separate factual determination as to whether we are or have become a PFIC must be made each year (after the close of such year), we cannot assure that we will not be or become a PFIC in the current year or any future taxable year.

 If we were to be classified as a PFIC for any taxable year during which a U.S. Holder5 holds our ADSs, we would continue to be treated as a PFIC with respect to that U.S. Holder for such taxable year and, unless the U.S. Holder makes certain elections, for future years even if we cease to be a PFIC. The U.S. Holder may be subject to adverse tax consequences, including (1) the treatment of all or a portion of any gain on disposition of our ADSs as ordinary income (and therefore ineligible for the preferential rates that apply to capital gains with respect to non-corporate U.S. persons), (2) the application of an interest charge with respect to such gain and on the receipt of certain dividends on our ADSs and (3) required compliance with certain reporting requirements. Each U.S. Holder is strongly urged to consult its tax advisor regarding the application of these rules and the availability of any potential elections. For further information regarding the U.S. federal income tax considerations relevant to our potential status as a PFIC, please see the section entitled "U.S. Federal Income Tax Considerations for U.S. Holders—PFIC Rules" in this Form 10-K.

 5 A U.S. Holder is (1) a legal and/or a beneficial owner of our ADSs and (2) a U.S. person for U.S. federal income tax purposes, specifically: (i) an individual who is a citizen or resident of the United States for U.S. federal income tax purposes; (ii) a corporation, or other entity treated as an association taxable as a corporation for U.S. federal income tax purposes, that is created in, or organized under the law of the United States, any state thereof or the District of Columbia; (iii) an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source or whether or not the income is effectively connected with the conduct of a U.S. trade or business; (iv) a trust, the administration of which is subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all substantial decisions of the trust; or (v) a person that has otherwise validly elected to be treated as a U.S. person under the U.S. Internal Revenue Code of 1986 (as amended).

 If a U.S. Holder is treated as owning at least 10% of our ADSs, such person may be subject to adverse U.S. federal income tax consequences.

 If a U.S. Holder is treated as owning (directly, indirectly, or constructively through attribution) at least 10% of the total value of our stock or at least 10% of the total combined voting power of all classes of our stock entitled to vote, such person may be treated as a "United States shareholder" ("U.S. Shareholder") with respect to each "controlled foreign corporation" ("CFC") in our group (if any). A non-U.S. entity treated as a corporation for U.S. tax purposes will constitute a CFC if one or more such U.S. Shareholders (generally defined as U.S. persons that—directly, indirectly, or constructively through attribution—own at least 10% of the vote or value of the entity) own in the aggregate more than 50% of the entity's total vote or value.

 If we are classified as both a CFC and a PFIC (as defined above), we generally will not be treated as a PFIC with respect to those U.S. Holders that are U.S. Shareholders during the period in which we are a CFC.

 We do not believe we are currently a CFC. However, no assurances can be given that we are not a CFC or that we will not become a CFC in the future. Because our group includes one or more U.S. corporations, certain of our non-U.S. corporate subsidiaries could be treated as CFCs (regardless of whether or not we are treated as a CFC). A U.S. Shareholder of a CFC may be required to report annually and include in its U.S. taxable income its pro rata share of "Subpart F income," "global intangible low-taxed income," and investments of earnings in U.S. property by CFCs, regardless of whether we make any distributions to our shareholders. Subpart F income generally includes dividends, interest, certain non-active rents and royalties, gains from the sale of securities and income from certain transactions with related parties, and "global intangible low-taxed income" generally consists of net income of the CFC, other than Subpart F income and certain other types of income, in excess of certain thresholds. In addition, a U.S. shareholder that realizes gain from the sale or exchange of shares in a CFC may be required to classify a portion of such gain as dividend income rather than capital gain.

 Failure to comply with such reporting requirements could result in adverse tax effects for U.S. Shareholders and potentially significant monetary penalties. An individual that is a U.S. Shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a U.S. Shareholder that is a U.S. corporation.

 The determinations of CFC status and U.S. Shareholder status are complex and includes attribution rules, the application of which are not entirely certain. We cannot provide any assurances that we will assist investors in determining whether any of our non-U.S. subsidiaries is treated as a CFC or whether any investor is a U.S. Shareholder, or that we will furnish to any U.S. Shareholders information that may be necessary to comply with the aforementioned obligations. A U.S. Holder should consult its advisors regarding the potential application of these rules to an investment in our ADSs.

 Item 1B. Unresolved Staff Comments
 We do not have any unresolved comments from the SEC staff.

 Item 1C. Cybersecurity
 Overview
 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 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.

 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 executive committees. The Governance Risk and Compliance Committee (the "GRCC"), composed of the CISO and certain members of our executive and leadership teams, 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"). The Information Security Committee (the "ISC"), a security-focused governance body including senior managers across the Company on information security activities, meets regularly to receive updates on KPIs and to review relevant standards and policies.

 As a member of both the GRCC and the ISC, 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 Standardization 27001 Information Security Management System Requirements ("ISO 27001") 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.

 Risk Management
 Our security team has several touch points within the business in order to adequately address and mitigate risks. 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 build new tools and solutions in an effort 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."

 Item 2. Properties
 Our headquarters are located in Paris, France, in an approximately 9,216 square meter facility, under a lease agreement expiring in March 2031. In addition, we had 29 offices in 17 countries as of December 31, 2023. We currently lease space in data centers from third-party hosting providers to operate our servers located in the U.S. (Texas, Virginia), France, the Netherlands, Singapore and Japan. The properties are used by each of our segments. We believe that our facilities are adequate for our current needs.

 Item 3. Legal Proceedings
 For a discussion of our legal proceedings, refer to Note. 20 Commitments and contingencies.

 Item 4. Mine Safety Disclosures
 Not applicable.

 Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
 Market Information
 Our ADSs have been listed on the Nasdaq Global Select Market ("Nasdaq") under the symbol "CRTO" since October 30, 2013. Prior to that date, there was no public trading market for ADSs or our ordinary shares.
 Holders
 As of January 31, 2024, there were 36 holders of record of our ordinary shares and 125 participants in DTC that held our ADSs. The actual number of holders is greater, and includes beneficial owners whose ADSs are held in street name by brokers and other nominees. This number of holders of record and DTC participants also does not include holders whose shares may be held in trust by other entities.
 ADS Performance Graph
 The following graph matches our cumulative five-year total shareholder return on our ADSs with the cumulative total returns of the Russell 2000 Index and the Nasdaq Internet Index. The graph tracks the performance of a $100 investment in our ADSs and in each index (with the reinvestment of all dividends) from December 31, 2018 to December 31, 2023. The returns shown are based on historical results and are not intended to suggest future performance.

 The foregoing performance graph and related information shall not be deemed "soliciting material" or to be "filed" with the SEC, nor shall such information be incorporated by reference into any future filings under the Securities Act or the Exchange Act, except to the extent we specifically incorporate it by reference into such filing.
 Dividends
 We have never declared or paid any cash dividends on our ordinary shares. We do not anticipate paying cash dividends on our equity securities in the foreseeable future and intend to retain all available funds and any future earnings to fund our growth.
 Subject to the requirements of French law and our by-laws, dividends may only be distributed from our statutory retained earnings. Dividend distributions, if any, will be made in euros and converted into U.S. dollars with respect to the ADSs, as provided in the deposit agreement. In addition, under the General RCF, we may not declare, make or pay dividends if our net debt to Adjusted EBITDA leverage ratio exceeds 2.0x.
 Purchases of Equity Securities by the Issuer and Affiliated Purchasers
 We spent $125 million on ADS repurchases in 2023, and we extended our previously authorized share repurchase program of up to $480 million of outstanding ADS to an increased amount of up to $630 million in February 2024. The following table provides certain information with respect to our purchases of our ADSs during the fourth fiscal quarter of 2023:

 (2) Average price paid per share excludes any broker commissions paid.
 Recent Sales of Unregistered Securities and Use of Proceeds
 There were no unregistered sales of equity securities during 2023.
 Exchange Controls & Ownership by Non-French Residents
 Under current French foreign exchange control regulations there are no limitations on the amount of cash payments that we may remit to residents of foreign countries. Laws and regulations concerning foreign exchange controls do, however, require that all payments or transfers of funds made by a French resident to a non-resident, such as dividend payments, be handled by an accredited intermediary. All registered banks and substantially all credit institutions in France are accredited intermediaries.

 Neither the French Commercial Code nor our by-laws presently impose any restrictions on the right of non-French residents or non-French shareholders to own and vote shares. However, (a) any non-French citizen, (b) any French citizen not residing in France, (c) any non-French entity or (d) any French entity controlled by one of the aforementioned persons or entities may have to file a declaration for statistical purposes with the Bank of France (Banque de France) within 20 working days following the date of certain direct foreign investments in us, including any purchase of our ADSs. In particular, such filings are required in connection with investments exceeding 15,000,000 that lead to the acquisition of at least 10% of our outstanding ordinary shares or voting rights or the crossing of either such 10% threshold. Violation of this filing requirement may be sanctioned by five years of imprisonment and a fine of up to twice the amount of the relevant investment. This amount may be increased fivefold if the violation is made by a legal entity.
 Further, any investment (i) by (a) an non-French citizen, (b) any French citizen not residing in France, (c) any non-French entity or (d) any French entity controlled by one of the aforementioned persons or entities, (ii) that will result in the relevant investor (a) acquiring control of any entity registered in France, (b) acquiring all or part of a business line of an entity registered in France, or (c) for non-EU or non-EEA investors crossing, directly or indirectly, alone or in concert, a 25% threshold of voting rights in an entity registered in France, and (iii) made in certain strategic industries, including activities likely to prejudice national defense interests, public policy or public security (such as cryptology, data capturing devices, data storage and IT systems) and research and development related to critical technologies (such as artificial intelligence and cybersecurity) is subject to the prior authorization of the French Ministry of Economy, which authorization may be conditioned on certain undertakings. For the purposes of (ii)(a) in the preceding sentence, ownership of at least 40% of our share capital or voting rights is regarded as a controlling interest, but a lower percentage might be held to be a controlling interest in certain circumstances depending upon factors such as the acquirer's intention, the acquirer's ability to elect directors, and financial reliance by the company on the acquirer.

 If an investment requiring the prior authorization of the French Minister of Economy is completed without such authorization having been granted, the French Minister of Economy, at its discretion, might direct the relevant investor to nonetheless (i) submit a request for authorization, (ii) have the previous situation restored at its own expense or (iii) amend the investment. The relevant investor further may be found criminally liable and may be sanctioned with a fine not to exceed the greater of the following amounts: (i) twice the amount of the relevant investment, (ii) 10% of the annual turnover before tax of the target company or (iii) 5 million (for a company) or 1 million (for a natural person).

 French Tax Consequences

 The following describes the material French income tax consequences to U.S. Holders (as defined below) of purchasing, owning and disposing of the ADSs and ordinary shares, or the Securities as in force on the date of this Form 10-K.
 This discussion does not purport to be a complete analysis or listing of all potential tax effects of the acquisition, ownership or disposition of our securities to any particular investor, and does not discuss tax considerations that arise from rules of general application or that are generally assumed to be known by investors. All of the following is subject to change. Such changes could apply retroactively and could affect the consequences described below.
 For the purposes of this discussion, the term "U.S. Holder" means a beneficial owner of securities that is (1) an individual who is not a French tax resident under French domestic rules / applicable double tax treaty provisions and who is a U.S. citizen or resident for U.S. federal income tax purposes, or (2) a U.S. domestic corporation or certain other entities created or organized in or under the laws of the U.S. or any state thereof, including the District of Columbia, or (3) otherwise subject to U.S. federal income taxation on a net income basis in respect of securities.
 If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds securities, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If a U.S. Holder is a partner in a partnership that holds securities, such holder is urged to consult its own tax adviser regarding the specific tax consequences of acquiring, owning and disposing of securities.

 This discussion applies only to investors that hold our securities as capital assets that have the U.S. dollar as their functional currency, that are entitled to treaty benefits under the "Limitation on Benefits" provision contained in the tax treaty between the Government of the U.S. and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital dated August 31, 1994, as amended by additional protocols of December 8, 2004 and January 13, 2009 ("The Treaty"), and whose ownership of the securities is not effectively connected to a permanent establishment or a fixed base in France.
 Certain U.S. Holders (including, but not limited to, U.S. expatriates, partnerships or other entities classified as partnerships for U.S. federal income tax purposes, banks, insurance companies, regulated investment companies, tax-exempt organizations, financial institutions, persons subject to the alternative minimum tax, persons who acquired the securities pursuant to the exercise of employee share options or otherwise as compensation, persons that own (directly, indirectly or by attribution) 5% or more of our voting stock or 5% or more of our outstanding share capital, dealers in securities or currencies, persons that elect to mark their securities to market for U.S. federal income tax purposes and persons holding securities as a position in a synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below.
 U.S. Holders are urged to consult their own tax advisers regarding the tax consequences of the purchase, ownership and disposition of securities in light of their particular circumstances, especially with regard to the "Limitations on Benefits" provision.
 Furthermore, specific rules apply in France with respect to French assets that are held by or in foreign trusts. These rules, among other things, provide for the inclusion of trust assets in the settlor's net assets for purpose of applying the French real estate wealth tax, for the application of French gift and inheritance tax to French assets held in trust, for a specific tax on capital on the French assets of foreign trusts not already subject to the French real estate wealth tax and for a number of French tax reporting and disclosure obligations. The following discussion does not address the French tax consequences applicable to securities held in trusts.
 If securities are held in trust, the settlor, trustee and beneficiary are urged to consult their own tax adviser regarding the specific tax consequences of acquiring, owning and disposing of securities.
 Purchasing Consequences

 Financial Transactions Tax

 Pursuant to Article 235 ter ZD of the French Tax Code ("FTC"), purchases of shares or ADSs of a French company listed on a regulated market of the European Union or an exchange formally acknowledged by the French Financial Market Authority ("AMF") are subject to a 0.3% French tax on financial transactions provided that the issuer's market capitalization exceeds 1 billion as of December 1 of the year preceding the taxation year.
 A list of companies whose market capitalization exceeds 1 billion as of December 1 of the year preceding the taxation year within the meaning of Article 235 ter ZD of the FTC is published annually by the French tax authorities. Pursuant to Regulations BOI ANNX 000467 20211229 issued on December 29, 2021, Criteo is currently not included in such list. Please note that such list may be updated from time to time, or may not be published anymore in the future. Moreover, Nasdaq, on which Criteo's ADSs are listed for trading, is not currently acknowledged by the AMF but this may change in the future. Consequently, Criteo's securities should not fall within the scope of the tax on financial transactions described above and purchasers of Criteo's securities in 2022 should not be subject to the tax on financial transactions.

 Registration Duties

 In the case where Article 235 ter ZD of the FTC is not applicable, transfers of shares which are not listed on a regulated market of the European Union or an exchange formally acknowledged by the AMF are subject to uncapped registration duties at the rate of 0.1%.

 Ownership Consequences

 Taxation of Dividends

 Dividends paid by a French corporation to non-residents of France are generally subject to French withholding tax at a rate of 25% or 12.8% for individuals. Dividends paid by a French corporation in a non-cooperative State or territory, as set out in the list referred to in Article 238-0 A of the FTC, will generally be subject to French withholding tax at a rate of 75%, except to the extent this French corporation can prove that the main purpose and effect of the distribution is not transfer such dividend income in a non-cooperative State or territory with a view to avoiding taxes. However, eligible U.S. Holders entitled to Treaty benefits under the "Limitation on Benefits" provision contained in the Treaty who are U.S. tax residents, as defined pursuant to the provisions of the Treaty may be subject to the withholding tax at a reduced rate (as described below).
 Under the Treaty, the rate of French withholding tax on dividends paid to an eligible U.S. Holder who is a U.S. tax resident as defined pursuant to the provisions of the Treaty, who is the ultimate owner of the distributed dividends, and whose ownership of the ordinary shares or ADSs is not effectively connected with a permanent establishment or fixed base that such U.S. Holder has in France, is generally reduced to 15%, or to 5% if such U.S. Holder is a corporation and owns directly or indirectly at least 10% of the share capital of the issuer, subject to certain procedural requirements discussed below.
 For U.S. Holders that are not individuals but are U.S. residents, as defined pursuant to the provisions of the Treaty, the requirements for eligibility for Treaty benefits, including the reduced 15% or 5% withholding tax rates contained in the "Limitation on Benefits" provision of the Treaty, are complicated, and certain technical changes were made to these requirements by the protocol of January 13, 2009. U.S. Holders are advised to consult their own tax advisers regarding their eligibility for Treaty benefits in light of their own particular circumstances.
 Dividends paid to an eligible U.S. Holder may immediately be subject to the reduced rates of 15% or 5% provided that such holder establishes before the date of payment that it is a U.S. resident under the Treaty by completing and providing the depositary with the applicable treaty forms (Form 5000 and Form 5001).
 Dividends paid to a U.S. Holder that has not filed the Form 5000 before the dividend payment date will be subject to French withholding tax at the rate of 12.8%, 25% in 2023, or 75% if paid in a non-cooperative State or territory (as defined in Article 238-0 A of the FTC). Such U.S. Holder may claim a refund from the French tax authorities of the amount withheld in excess of the Treaty rates of 15% or 5%, if any, provided that such holder duly completes and provides the French tax authorities with the treaty forms (Form 5000 and Form 5001) before December 31 of the second calendar year following the year during which the dividend is paid. Certain qualifying pension funds and certain other tax-exempt entities are subject to the same general filing requirements as other U.S. Holders except that they may have to supply additional documentation evidencing their entitlement to these benefits.
 Form 5000 and Form 5001, together with instructions, will be provided by the depositary to all U.S. Holders registered with the depositary. The depositary will arrange for the filing with the French Tax authorities of all such forms properly completed and executed by U.S. Holders of ordinary shares or ADSs and returned to the depositary in sufficient time so that they may be filed with the French tax authorities before the distribution in order to obtain immediately a reduced withholding tax rate.
 The withholding tax refund, if any, will not occur before January 15 of the year following the calendar year in which the related dividend was paid.
 Subject to certain conditions, corporations can obtain a full refund of the withholding tax if they are in loss-making position. In such case, the taxation is deferred and will occur if and when profits are made.
 Because the withholding tax rate applicable under French domestic law to U.S. holders who are individuals does not exceed the cap provided in the Treaty (i.e. 15%), the domestic 12.8% withholding tax rate will generally apply to dividends paid to those U.S. holders, as opposed to the rate provided under the Treaty.

 Wealth Tax

 As from January 1, 2018, French wealth tax (imp t de solidarit sur la fortune) has been replaced by the real estate wealth tax (imp t sur la fortune immobili re) which applies to French tax residents on their worldwide real estate assets and non-French tax resident individuals owning French real estate assets or rights, directly or indirectly through one or more legal entities, and whose net taxable assets amount to at least 1,300,000 euros. Generally, real estate assets allocated to an operational activity are excluded from the scope of the real estate wealth tax, depending on the structuring. Shares of an operating company holding French real estate assets in which the relevant individual holds, directly and indirectly, less than 10% of the share capital or voting rights, are also exempt from real estate wealth tax.
 The Treaty does not prevent the application of French real estate wealth tax to a U.S. Holder who would be a U.S. tax resident. However, based on the above domestic provisions and considering that Criteo SA is an operating company, the owning of ADSs or ordinary shares should not be subject to real estate wealth tax.
 Disposition

 Taxation on sale or other disposition

 Generally, under French tax law, a foreign shareholder who is not a French tax resident for French tax purposes is not subject to French tax on any capital gain from the sale, exchange, repurchase or redemption of ordinary shares or ADSs, provided that this shareholder has not held more than 25% of our dividend rights, at any time during the preceding five years, either directly or indirectly, and, as relates to individuals, alone or with relatives (as an exception, a non-resident shareholder established, domiciled or incorporated in a non-cooperative State or territory as defined in Article 238-0 A of the FTC should be subject to a 75% withholding tax in France on any such capital gain, regardless of the fraction of the dividend rights it holds).

 However, based on the Treaty, a U.S. Holder who is a U.S. tax resident for purposes of the Treaty, has no permanent establishment or fixed base in France within the meaning of the Treaty, and is entitled to Treaty benefits will only be subject to French tax on capital gain resulting from the sale of shares, units or rights in a company at least 50% of the assets of which consist of real estate located in France, or derives at least 50% of its value, directly or indirectly, from real estate located in France. Criteo SA is not expected to meet this standard. Pursuant to these provisions, capital gain resulting from the sale or other disposition of ADSs and ordinary shares should not be subject to taxation in France for this shareholder. U.S. Holders who own ordinary shares or ADSs through U.S. partnerships that are not residents for Treaty purposes are advised to consult their own tax advisors regarding their French tax treatment and their eligibility for Treaty benefits in light of their own particular circumstances.

 A U.S. Holder who owns ordinary shares or ADSs through U.S. partnerships that are not residents for Treaty purposes are advised to consult their own tax advisors regarding their French tax treatment and their eligibility for Treaty benefits in light of their own particular circumstances.

 A U.S. Holder that is not a U.S. resident for Treaty purposes or is not entitled to Treaty benefits (and in both cases is not resident, established or incorporated in a non-cooperative State or territory as defined in Article 238-0 A of the FTC) and has held more than 25% of Criteo's dividend rights at any time during the preceding five years, either directly or indirectly, and, as relates to individuals, alone or with relatives will be subject to a levy in France at the rate of (i) 25% if such U.S. Holder is a corporate body or a legal entity, or (ii) 12.8% if such U.S. Holder is an individual.

 Special rules apply to U.S. Holders who are residents of more than one country.

 Gift and Inheritance Tax

 Generally, under French tax law, the following assets are subject to gift and inheritance tax:
 • all movable or immovable property located in France or outside France when the donor or the deceased had his or her tax residence in France within the meaning of Article 4 B of the FTC;
 • movable or immovable property located in France (including French real estate assets held indirectly), when the donor or the deceased is not domiciled for tax purposes in France;

 • movable and immovable property located in France or outside France received from a donor or deceased domiciled outside France by an heir, donee or legatee who is domiciled for tax purposes in France within the meaning of Article 4 B of the FTC and has been so domiciled for at least six years during the last ten years preceding the year in which he or she receives the property.

 However, under the Convention between the Government of the U.S. and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978 (as amended by the protocol of December 8, 2004 and as amended on January 13, 2019), if the U.S. Holder is domiciled in the U.S. and is a U.S. tax resident for purposes of the Treaty, has no permanent establishment or fixed base in France within the meaning of the Treaty, and is entitled to Treaty benefits, only French real estate assets and shares, units or other interests in a company or legal entity whose assets consist, directly or through one or more other companies or legal entities, of at least 50% of real property located in France or of rights relating to such property can be subject to gift and inheritance tax.

 U.S. Federal Income Tax Considerations for U.S. Holders

 The following section is a summary of the U.S. federal income tax considerations generally applicable to U.S. Holders, as defined below, of owning and disposing of ADSs or ordinary shares.

 This section applies only to a U.S. Holder that holds ADSs or ordinary shares as capital assets (generally, property held for investment) for U.S. federal income tax purposes. This section does not address the U.S. federal estate, gift or other non-income tax considerations or any state, local or non-U.S. tax considerations relating to the ownership or disposition of ADSs or ordinary shares. In addition, it does not set forth all of the U.S. federal income tax considerations that may be relevant in light of the U.S. Holder's particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), known as the Medicare contribution tax and tax consequences applicable to U.S. Holders subject to special rules, such as:
 • certain banks and other financial institutions;
 • dealers in securities or currencies;
 • traders that elect to use a mark-to-market method of accounting;
 • persons holding ADSs or ordinary shares as part of a hedging transaction, straddle, wash sale, conversion transaction or other integrated transaction or persons entering into a constructive sale with respect to the ADSs or ordinary shares;
 • persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;
 • entities or arrangements classified as partnerships for U.S. federal income tax purposes;
 • insurance companies;
 • pension plans;
 • cooperatives;
 • regulated investment companies;
 • real estate investment trusts;
 • tax-exempt entities, including private foundations and "individual retirement accounts" or "Roth IRAs";
 • certain former U.S. citizens or long-term residents;
 • persons who acquire their ADSs or ordinary shares pursuant to any employee share option or otherwise as compensation;

 • persons required for U.S. federal income tax purposes to conform the timing of income accruals with respect to the ADSs or ordinary shares to their financial statements under Section 451(b) of the Code;
 • persons that directly, indirectly or constructively own 10% or more of our shares (by vote or value); or
 • persons holding ADSs or ordinary shares in connection with a trade or business conducted outside of the U.S.

 If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds ADSs or ordinary shares, the U.S. federal income tax treatment of a partner will depend on the status of the partner and the activities of the partnership. Partnerships holding ADSs or ordinary shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the ADSs or ordinary shares.

 Each U.S. Holder should consult its tax advisor as to the U.S. federal, state, local and non-U.S. tax considerations relevant to it with respect to the ownership and disposition of our ADSs or ordinary shares in light of its particular circumstances.

 This section is based on the Code, administrative pronouncements, judicial decisions, final Treasury regulations, and the income tax treaty between France and the U.S. (the "Treaty"), all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

 A "U.S. Holder" is a holder who, for U.S. federal income tax purposes, is a beneficial owner of ADSs or ordinary shares and who is:
 • a citizen or individual resident of the U.S.;
 • a corporation, or other entity classified as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S., any state thereof or the District of Columbia;
 • an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or
 • a trust if a court within the U.S. is able to exercise primary supervision over the administration of the trust and one or more U.S. persons has or have the authority to control all of the trust's substantial decisions, or the trust has validly elected to be treated as a domestic trust for U.S. federal income tax purposes.

 In general, it is expected that a U.S. Holder who owns ADSs will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. The remainder of this discussion assumes that a U.S. Holder of our ADSs will be treated in this manner. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.

 U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of ADSs or ordinary shares in their particular circumstances.

 Taxation of Distributions

 We do not currently expect to make distributions on our ADSs or ordinary shares. If we are not and have not been a PFIC (as discussed below in the section entitled "PFIC Rules"), in the event that we do make distributions of cash or other property, the following rules would apply. The gross amount of any distributions paid on ADSs or ordinary shares, other than certain pro rata distributions of ADSs or ordinary shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent such amount is treated as a dividend, it will generally be includible in the gross income of a U.S. Holder as dividend income on the day actually or constructively received by the U.S. Holder, in the case of ordinary shares, or by the depositary, in the case of ADSs.
 If distributions exceed our current and accumulated earnings and profits, such excess distributions will generally constitute a return of capital to the extent of the U.S. Holder's tax basis in its ADSs or ordinary shares and will result in a reduction thereof.

 To the extent such excess exceeds a U.S. Holder's tax basis in the ADSs or ordinary shares, such excess will generally be subject to tax as capital gain. Because we do not intend to determine our earnings and profits in accordance with U.S. federal income tax principles, the full amount of any distribution we pay is generally expected to be treated as a dividend for U.S. federal income tax purposes. Dividends received on our ADSs or ordinary shares will not be eligible for the dividends received deduction allowed to corporations in respect of dividends received from U.S. corporations.

 Individuals and other non-corporate U.S. Holders will be subject to tax at the lower capital gains tax rate applicable to "qualified dividend income," provided that certain conditions are satisfied, including that (1) the ADSs or ordinary shares on which the dividends are paid are readily tradable on an established securities market in the U.S., or we are eligible for the benefits of the Treaty, (2) we are neither a PFIC nor treated as such with respect to a U.S. Holder (as discussed below) for the taxable year in which the dividend is paid or the preceding taxable year, and (3) certain holding period requirements are met.

 If we are eligible for benefits under the Treaty, dividends we pay on our ADSs or ordinary shares, regardless of whether such ADSs or shares are considered readily tradable on an established securities market in the U.S., would be eligible for the reduced rates of taxation described in the preceding paragraph, provided the other conditions described above are satisfied. Further, as discussed below under "PFIC Rules", although there can be no assurance that we will or will not be considered a PFIC for any taxable year, we believe we were not a PFIC for our 2022 taxable year and we do not anticipate that we will be a PFIC in the current and future taxable years. U.S. Holders should consult their tax advisors regarding the availability of the reduced tax rate on dividends in their particular circumstances.

 For U.S. foreign tax credit purposes, dividends paid on our ADSs or ordinary shares generally will be treated as income from foreign sources and generally will constitute passive category income. The amount of any dividend income paid in euro will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into U.S. dollars at that time.

 If the foreign currency received as a dividend is converted into U.S. dollars on the date it is received, a U.S. Holder will generally not be required to recognize foreign currency gain or loss in respect of the dividend income. If the foreign currency received as a dividend is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any gain or loss realized on a subsequent conversion or other disposition of the foreign currency will be treated as U.S. source ordinary income or loss.

 Sale or Other Disposition of ADSs or Ordinary Shares

 Subject to the discussion below under "PFIC Rules", gain or loss realized on the sale or other disposition of ADSs or ordinary shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the ADSs or ordinary shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder's tax basis in the ADSs or ordinary shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. Long-term capital gain of individuals and certain other non-corporate U.S. Holders will generally be eligible for a reduced rate of taxation. The deductibility of a capital loss may be subject to limitations. Any capital gain or loss will generally be treated as U.S.-source gain or loss for U.S. foreign tax credit purposes, which will generally limit the availability of foreign tax credits.

 PFIC Rules

 Under the Code, we will be a PFIC for any taxable year in which either (i) 75% or more of our gross income consists of "passive income," or (ii) 50% or more of the average quarterly value of our assets consist of assets that produce, or are held for the production of, "passive income." For purposes of the above calculations, we will be treated as if we hold our proportionate share of the assets of, and receive directly our proportionate share of the income of, any other corporation in which we directly or indirectly own at least 25%, by value, of the shares of such corporation.

 Passive income includes, among other things, interest, dividends, certain non-active rents and royalties, net gains from the sale or exchange of property producing such income and net foreign currency gains.
 For this purpose, cash and assets readily convertible into cash are categorized as passive assets, and our goodwill and other unbooked intangibles are taken into account.
 The determination of whether we are a PFIC is a fact-intensive determination that must be made on an annual basis applying principles and methodologies that are in some circumstances unclear.

 Based on the value and composition of our assets, although not free from doubt, we do not believe we were a PFIC for the taxable year ended December 31, 2023, and we do not expect to be a PFIC in the current taxable year or the foreseeable future. Since a separate factual determination as to whether we are or have become a PFIC must be made each year (after the close of such year), we cannot assure you that we will not be or become a PFIC in the current year or any future taxable year.

 If we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, the PFIC rules discussed below generally will apply to such U.S. Holder for such taxable year, and unless the U.S. Holder makes certain elections, will apply in future years even if we cease to be a PFIC.

 If we were a PFIC for any taxable year during which a U.S. Holder held ADSs or ordinary shares (assuming such U.S. Holder has not made a timely mark-to-market or QEF election, as described below), gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of the ADSs or ordinary shares would be allocated ratably over the U.S. Holder's holding period for the ADSs or ordinary shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an additional tax based on the interest charge generally applicable to underpayments of tax would be imposed on the amount allocated to that taxable year. Further, to the extent that any distribution received by a U.S. Holder on its ADSs or ordinary shares exceeds 125% of the average of the annual distributions on the ADSs or ordinary shares received during the preceding three years or the U.S. Holder's holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above.

 If we are a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares and any of our non-U.S. affiliated entities are also PFICs, the holder will be treated as owning a proportionate amount (by value) of the shares of each such non-U.S. affiliate classified as a PFIC for purposes of the application of these rules. U.S. Holders are urged to consult their tax advisors regarding the application of the PFIC rules to any of our subsidiaries.

 A U.S. Holder can avoid certain of the adverse rules described above by making a mark-to-market election with respect to its ADSs or ordinary shares, provided that the ADSs or ordinary shares are "marketable." ADSs or ordinary shares will be marketable if they are traded in other than de minimis quantities on at least 15 days during each calendar quarter ("regularly traded") on a "qualified exchange" or other market within the meaning of applicable Treasury regulations. We expect that our ADSs, but not our ordinary shares, will continue to be listed on the Nasdaq Global Select Market, which is a qualified exchange for these purposes, but no assurances may be given in this regard. Consequently, assuming that our ADSs are regularly traded, if a U.S. Holder holds our ADSs, it is expected that the mark-to-market election would be available to such holder were we to be or become a PFIC. In addition, because, as a technical matter, a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder may continue to be subject to the PFIC rules with respect to such holder's indirect interest in any investments held by us that are treated as an equity interest in a PFIC for U.S. federal income tax purposes.

 If a U.S. Holder makes the mark-to-market election, it will recognize as ordinary income any excess of the fair market value of the ADSs or ordinary shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ADSs or ordinary shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes the election, the U.S. Holder's tax basis in the ADSs or ordinary shares will be adjusted to reflect the income or loss amounts recognized.

 Any gain recognized on the sale or other disposition of ADSs or ordinary shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes such a mark-to-market election, tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us (except that the lower applicable capital gains rate for qualified dividend income would not apply). If a U.S. Holder makes a valid mark-to-market election, and we subsequently cease to be classified as a PFIC, such U.S. Holder will not be required to take into account the mark-to-market income or loss described above during any period that we are not classified as a PFIC.

 In addition, in order to avoid the application of the foregoing rules, a U.S. person that owns shares in a PFIC for U.S. federal income tax purposes may make a "qualified electing fund" ("QEF") election with respect to such PFIC, if the PFIC provides the information necessary for such election to be made. If a U.S. person makes a QEF election with respect to a PFIC, the U.S. person will be currently taxable on its pro rata share of the PFIC's ordinary earnings and net capital gain (at ordinary income and capital gain rates, respectively) for each taxable year that the entity is classified as a PFIC and will not be required to include such amounts in income when actually distributed by the PFIC. No assurances can be given that we will provide holders with the information necessary for U.S. Holders to make a QEF election.

 In addition, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

 If a U.S. Holder owns ADSs or ordinary shares during any year in which we are a PFIC, the U.S. Holder must file annual reports, containing such information as the U.S. Department of the Treasury may require on IRS Form 8621 (or any successor form) with respect to us, with the U.S. Holder's federal income tax return for that year, unless otherwise specified in the instructions with respect to such form.

 U.S. Holders should consult their tax advisers concerning our potential PFIC status and the potential application of the PFIC rules.

 THE PRECEDING SUMMARY OF U.S. FEDERAL INCOME TAX CONSIDERATIONS IS INTENDED FOR GENERAL INFORMATION ONLY AND DOES NOT CONSTITUTE TAX ADVICE. U.S. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. TAX CONSIDERATIONS GENERALLY APPLICABLE TO THEM OF THE OWNERSHIP AND DISPOSITION OF OUR ADSs OR ORDINARY SHARES IN THEIR PARTICULAR CIRCUMSTANCES.

 Item 6. [Reserved]

 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
 The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Form 10-K.

 To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), we present Contribution ex-TAC, and Adjusted EBITDA, which are non-GAAP financial measures. We define Contribution ex-TAC as a profitability measure akin to gross profit. It is calculated by deducting traffic acquisition costs from revenue and reconciled to gross profit through the exclusion of other costs of revenue. Contribution ex-TAC is presented in the section entitled "Contribution excluding Traffic Acquisition Costs", which includes a reconciliation to its most directly comparable U.S. GAAP financial measure, Gross Profit. We define Adjusted EBITDA as our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, certain acquisition costs and a loss contingency related to a regulatory matter. Adjusted EBITDA is presented in the section entitled "Adjusted EBITDA", which includes a reconciliation to its most directly comparable U.S. GAAP financial measure, Net Income. We also present revenues, traffic acquisition costs and Contribution ex-TAC on a constant currency basis; these measures exclude the impact of foreign currency fluctuations and are computed by applying the average exchange rates for the prior year to the current year figures. A reconciliation is provided in the section entitled "Constant Currency Reconciliation".

 We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key metrics used by management in operating our business. As required by the rules of the SEC, we provide reconciliations of the non-GAAP financial measures contained in this document to the most directly comparable measures under GAAP.
 Overview
 We are a global technology company driving superior commerce outcomes for marketers and media owners through the world's leading Commerce Media Platform. We operate in commerce media, the future of digital advertising, leveraging commerce data and artificial intelligence ("AI") to connect ecommerce, digital marketing and media monetization to reach consumers throughout their shopping journey. Our vision is to bring richer experiences to every consumer by supporting a fair and open internet that enables discovery, innovation, and choice – powered by trusted and impactful advertising. We have accelerated and deeply transformed the Company from a single-product to a multi-solution platform provider, fast diversifying our business into new solutions.
 We have reported our results as three reportable segments: Marketing Solutions, Retail Media and Iponweb.
 Beginning in the first quarter of 2024 – following the completion of the integration of our Iponweb acquisition – our Chief Operating Decision Maker, who is our Chief Executive Officer ("CEO"), no longer receives disaggregated information for Iponweb. As such, we will update our segment financial reporting structure in line with how our CEO assesses performance and allocates resources. We will have two segments: Retail Media and Performance Media. Performance Media combines our former Marketing Solutions and Iponweb segments.

 Full Year 2023 financial highlights
 For the year ended December 31, 2023, revenue was $1,949.4 million, down 3% compared to the prior year, reflecting growth in Retail Media and Iponweb offset by lower revenue in Marketing Solutions. At constant currency, revenue was down 3%.

 Gross profit for the year ended December 31, 2023 increased by 9% to $863.0 million, compared to the prior year, primarily due to lower traffic acquisition costs.
 Contribution ex-TAC for the year ended December 31, 2023 increased by 10% to $1,022.6 million, compared to the prior year, driven by growth in Retail Media and Iponweb. At constant currency, Contribution ex-TAC increased by 11%. In Q4 2023, new solutions represented approximately 56% of Contribution excluding Traffic Acquisition Costs, or Contribution ex-TAC, which is a non-U.S. GAAP financial measure, compared to 47% in Q4 2022.
 Net income for the year ended December 31, 2023 increased by 402% to $54.6 million, compared to the prior year, primarily due to lower traffic acquisition costs and lower operating expenses.
 Adjusted EBITDA for the year ended December 31, 2023 increased by 13% to $301.8 million, compared to the prior year, primarily due to higher Contribution ex-TAC and planned cost reduction actions.

 Cash flow from operating activities was $224.2 million for the year ended December 31, 2023, compared to $256.0 million in the prior year.

 Trends, Opportunities and Challenges
 We believe our performance and future success depend on several factors that present significant opportunities but also pose risks and challenges, including those referred to in Part I, Item 1A.
 Develop and Scale our Commerce Media Platform
 Our future growth depends upon our ability to retain and scale our existing clients and increase the usage of our Commerce Media platform as well as adding new customers. We believe that we are in a leading position in the Commerce Media space as we have unique commerce data at scale, deep integrations with retailers, a large client base, differentiated technology and a R&D powerhouse. By unifying the Commerce Media ecosystem with a multi-retailer, multi-channel, multi-format approach and providing full funnel closed loop measurement to our clients, we believe we are well positioned to capture more ad budgets and market share.

 Business and Macroeconomic Conditions

 Global economic and geopolitical conditions have been increasingly volatile due to factors such as the conflicts in Ukraine and the Middle East, inflation, and high interest rates. The economic uncertainty resulting from these factors has negatively impacted advertising demand, consumer behavior, and to some extent our performance.

 These factors, among others, including the impact of persistent inflation, make it difficult for Criteo and our clients to accurately forecast and plan future business activities, and could cause the company's clients to reduce or delay their advertising spending or increase their cautiousness, which, in turn, could have an adverse impact on our business, financial condition and results of operations. We are monitoring these macroeconomic conditions closely and may continue to take actions in response to such conditions to the extent they adversely affect our business.
 Seasonality
 In the advertising industry, companies commonly experience seasonal fluctuations in revenue, as many marketers allocate the largest portion of their budgets to the third and fourth quarter of the calendar year in order to coincide with increased back-to-school and holiday purchasing. Historically, the fourth quarter has reflected our highest level of advertising activity for the year. We generally expect the subsequent first quarter to reflect lower activity levels, but this trend may be masked due to the growth of our business. In addition, historical seasonality may not be predictive of future results given the potential for changes in advertising buying patterns and consumer activity due to the potential impacts of the evolving macroeconomic and geopolitical conditions discussed above. We expect our revenue to continue to fluctuate based on seasonal factors that affect the advertising industry as a whole.

 Privacy Trends and Government Regulations
 We are subject to U.S. and international laws and regulations regarding privacy, data protection, digital advertising and the collection of user data. In addition, large Internet and technology companies such as Google and Apple are making their own decisions as to how to protect consumer privacy with measures resulting in signal loss, which impact the entire digital ecosystem. Google's web browser, Chrome, announced plans to deprecate support for third-party cookies in the second half of 2024, which will follow a one-percent deprecation of third-party cookies for Chrome users globally in the first quarter of 2024. These developments could cause instability in the advertising technology industry. We have developed a multi-pronged addressability strategy to enhance our resilience post third-party identifiers.

 A. Operating Results.
 Critical Accounting Policies and Estimates
 Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of revenue, assets, liabilities, costs and expenses. 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.
 An accounting policy is deemed to be critical if it requires an accounting estimate to be made on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably possible could materially impact the financial statements. We believe estimates associated with (1) gross vs net assessment in revenue recognition, (2) income taxes, including i) recognition of deferred tax assets arising from the subsidiaries projected taxable profit for future years, ii) evaluation of uncertain tax positions associated with our transfer pricing policy and iii) recognition of income tax position in respect with tax reforms recently enacted in countries we operate, (3) assumptions used in valuing long-lived assets including intangible assets, and goodwill, and (4) assumptions surrounding the recognition and valuation of contingent liabilities and losses, are critical as they are made based on assumptions about matters which are uncertain. See Note 1. Principles and Accounting Methods to our audited consolidated financial statements beginning on page F-1 for a description of our other significant accounting policies.
 Revenue Recognition - Gross vs Net Assessment
 For revenue generated from arrangements that involve purchasing inventory from media owners, there is significant judgment in evaluating whether we are the principal, and report revenue on a gross basis, or the agent, and report revenue on a net basis. In this assessment, we consider if we obtain control of the specified goods or services before they are transferred to the customer, as well as other indicators such as the determination of the party primarily responsible for fulfillment of the promised service, inventory risk, and discretion in establishing price. The assessment of whether we are considered the principal or the agent in a transaction could impact our revenue and cost of revenue recognized in the consolidated statements of income.
 For additional information regarding revenue and the assumptions used for determining our revenue recognition refer to Note 1. Principles and Accounting Methods of our financial statements.
 Income taxes
 We are subject to income taxes in France and numerous foreign jurisdictions. We record deferred taxes on all temporary differences between the financial reporting and tax bases of assets and liabilities, and on tax losses, using the liability method. 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 the deferred tax assets, which could have a significant impact on our financial results.
 We also 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 and development 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.
 Valuation of Long-lived Assets including Goodwill, and Intangible Assets
 We allocate the fair value of purchase consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill to reporting units based on the expected benefit from the business combination. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets.

 Significant estimates in valuing certain intangible assets include, but are not limited to, estimated replacement costs and future expected cash flows from acquired users, acquired technology, acquired patents, and trade names from a market participant perspective, useful lives, and discount rates. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Allocation of purchase consideration to identifiable assets and liabilities affects our amortization expense, as acquired finite-lived intangible assets are amortized over the useful life, whereas any indefinite-lived intangible assets, including goodwill, are not amortized. During the measurement period, which is not to exceed one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.

 Goodwill is tested for impairment at the reporting unit level annually or more frequently if events or changes in circumstances would more likely than not reduce the fair value of a reporting unit below its carrying value. Goodwill has been allocated to segments using a relative fair value allocation approach. As of December 31, 2023, no impairment of goodwill has been identified.
 Long-lived assets, including property and equipment and finite-lived intangible assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate from the use and eventual disposition. If such review indicates that the carrying amount of property and equipment and intangible assets is not recoverable, the carrying amount of such assets is reduced to fair value.
 Contingent Losses and Liabilities
 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 non income tax audits. These judgment and estimates are subject to change as new information becomes available.
 Components of Results of Operations
 The key elements of our results of operations include:
 Revenue
 For Marketing Solutions, we generate revenues by delivering personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. Such products are generally sold based on a cost-per-click or cost-per-impression pricing models. Revenues are recognized when an ad is clicked on or displayed to the end user as that is 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. The cost-per-click or cost-per-impression we charge to the customers, varies depending on the optimization strategy of the Criteo engine, the dynamics and performance of the market, amongst other factors. Marketing solutions revenue is primarily recognized on a gross basis as we act as a principal in the transaction.
 For Retail Media, we generate revenue by providing our platform to brands, agencies and retailers for the purchase and sale of digital advertising inventory. Generally, our revenue is based on a percentage of working media spend that runs through our platform. We earn revenue by applying a margin to the amount of working media spend that runs through the platform. The working media spend running through the platform depends on various factors, such as but not limited to, the number of customers using the platform and the budgets allocated by brands and agencies to the Criteo platform. The margin applied by Criteo to the working media spend is dependent on the market dynamics, sector and industry of the customers. Retail Media revenue is primarily recognized on a net basis, as we act as an agent in the transaction.
 We act as agent in Iponweb 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.

 Refer to Note 1. Principles and Accounting Methods of our financial statements for a description of our revenue recognition policies.
 Cost of Revenue
 Our cost of revenue 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, for the Marketing Solutions 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. For a discussion of the trends we expect to see in traffic acquisition costs, see the section entitled " - Highlights and Trends - Contribution ex-TAC" in Item 7.E -Trend Information below.
 Other Cost of Revenue. Other cost of revenue includes expenses related to third-party hosting fees, depreciation of data center equipment, the cost of 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.
 Operating Expenses
 Operating expenses consist of research and development, sales and operations, and general and administrative expenses. Salaries, bonuses, equity awards compensation, pension benefits and other personnel-related costs are the most significant components of each of these expense categories.
 Research and Development Expense. Research and development expense consists primarily of personnel-related costs for our employees working in the engine, platform, site reliability engineering, scalability, infrastructure, engineering program management, product, analytics and other teams, including salaries, bonuses, equity awards 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 that is conditional upon the level of our expenditures in research and development.
 Sales and Operations Expense. Sales and operations expense consists primarily of personnel-related costs 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, equity awards 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, and depreciation and amortization costs.
 General and Administrative Expense. General and administrative expense consists primarily of personnel costs, including salaries, bonuses, equity awards 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 and depreciation and amortization costs.
 Financial and Other Income (Expense) primarily consists of:
 • Exchange differences arising on the settlement or translation into local currency of monetary balance sheet items labeled in euros (the Company's functional currency). At December 31, 2023, our exposure to foreign currency risk was centralized at parent company level and hedged. These exchange differences in euro are then translated into U.S. dollars (the Company's reporting currency) according to the average euro/U.S. dollar exchange rate.
 • Interest received on our cash and cash equivalents and interest incurred on outstanding borrowings under our debt loan agreements and revolving credit facilities ("RCFs").
 • Other income (expense) mainly arising from gains and losses on investments.

 Provision for Income Taxes
 We are subject to potential income taxes in France, the U.S. and numerous other jurisdictions. We recognize tax liabilities based on estimates of whether additional taxes will be due. These tax liabilities are recognized when we believe that certain positions may not be fully sustained upon review by tax authorities, notwithstanding our belief that our tax return positions are supportable.
 Our effective tax rates differ from the statutory rate applicable to us primarily due to valuation allowance on deferred tax assets, differences between domestic and foreign jurisdiction tax rates, Research Tax Credit offsets, which are non-taxable items, potential tax audit provision settlements, share-based compensation expenses that are non-deductible in some jurisdictions under certain circumstances, non-tax deductible provision from the loss contingency on regulatory matter, and transfer pricing adjustments. We license access to our technology to our subsidiaries and charge a royalty fee to these subsidiaries for such access. In France, we benefit from a reduced tax rate of 10% on a large portion of this technology royalty income.

 Revenue in 2023 decreased $(67.6) million, or (3)% (or (3)% on a constant currency basis) to $2.0 billion compared to 2022.

 The year-over-year decrease in revenue was driven by lower Marketing Solutions revenue, partially offset by the increase in Retail Media and Iponweb revenue. Marketing Solutions revenue decreased (8)% (or (8)% on a constant currency basis) to $1.6 billion for 2023, reflecting decreased spend from large clients, notably on our retargeting solutions, as they adjusted their advertising budgets to the uncertain macro economic environment.
 Retail Media revenue increased 3% (or 3% on a constant currency basis) to $209.0 million for 2023, reflecting the strong performance with large retailers across the U.S. and EMEA, partially offset by the technical and transitory impact related to the client migration to the Company's platform. Criteo's platform accounted for most of Retail Media revenue for the year ended December 31, 2023, and its revenue is accounted for on a net basis. In 2022, close to 79% of Retail Media revenue was accounted for on a net basis, and as a result of this transition to a full platform business, the growth of Retail Media revenue was temporarily impacted. Reflecting the underlying economic performance, Retail Media's Contribution ex-TAC increased 26% (or 26% on a constant currency basis) in the year ended December 31, 2023, mainly driven by strength in the U.S. market.

 2022 compared to 2021

 Revenue in 2022 decreased $(237.2) million, or (11)% (or (4)% on a constant currency basis) to $2.0 billion compared to 2021. The year-over-year decrease in revenue was driven by lower Marketing Solutions revenue and the technical impact of the Retail Media transition to a full platform business, partially offset by the positive contribution from Iponweb. Marketing Solutions revenue decreased (12)% (or (5)% on a constant currency basis) to $1.8 billion for 2022, reflecting decreased spend from large clients, notably on our retargeting solutions, as they adjusted their advertising budgets to the current uncertain macro economic environment. Retail Media revenue decreased (18)% (or (16)% on a constant currency basis) to 202.3 million for 2022, as the strong performance with large retailers across the U.S. and EMEA was more than offset by the technical and transitory impact related to the ongoing client migration to the Company's platform. Criteo's platform accounted for the majority of Retail Media revenue, or close to 79% for the year ended December 31, 2022, and its revenue is accounted for on a net basis. In 2021, around 50% of Retail Media revenue was accounted for on a net basis, and as a result of this transition to a full platform business, the growth of Retail Media revenue was temporarily impacted. Reflecting the underlying economic performance, Retail Media's Contribution ex-TAC increased 29% (or 33% on a constant currency basis) in the year ended December 31, 2022, mainly driven by continued strength in Retail Media onsite, particularly in the U.S. market.

 Our revenue in the Americas region decreased $(4.0) million or (0.5)% (or (1)% on a constant currency basis) to $887.2 million for 2023 compared to 2022. This reflects negative retail trends in Marketing Solutions and the impact of recognizing revenue on a net basis for clients transitioning to the Company's platform, partially offset by the continued strong performance of Retail Media, as the platform continues to scale with consumer brands and large retailers and growing network effects of the platform.

 Our revenue in the EMEA region decreased $(34.3) million, or (5)% (or (9%) on a constant currency basis) to $672.6 million for 2023 compared to 2022. This decrease was driven by negative retail trends in Marketing Solutions, in particular in the UK and France, and the suspension of our business in Russia effective as of March 2022, partially offset by the positive performance of Retail Media across the region.

 Our revenue in the Asia-Pacific region decreased $(29.3) million, or (7)% (or increased 3% on a constant currency basis) to $390 million for 2023 compared to 2022. The increase was driven by higher spend from retail clients in the region, in particular in Thailand and South Korea.
 Additionally, $1,949 million of revenue for 2023 was negatively impacted by $8.9 million of currency fluctuations, particularly as a result of the appreciation of the Euro compared to the U.S. dollar.

 Our revenue in the Americas region decreased $(25.6) million, or (3)% (or (3)% on a constant currency basis) to $891.3 million for 2022 compared to 2021. This decrease was driven by negative retail trends, in particular with large customers across Marketing Solutions and by the impact of recognizing revenue on a net basis for clients transitioning to the Company's platform, partially offset by the continued strong performance of Retail Media, as the platform continues to scale with consumer brands and large retailers and growing network effects of the platform.

 Our revenue in the EMEA region decreased $(137.5) million, or (16)% (or (6)% on a constant currency basis) to $706.9 million for 2022 compared to 2021. This decrease was driven by the suspension of our business in Russia effective as of March 2022, and by the continued decline in retail over the year in our main Marketing Solutions markets, in particular in France, UK and Germany, partially offset by the positive performance of Retail Media across the region.
 Our revenue in the Asia-Pacific region decreased $(74.2) million, or (15)% (or (3)% on a constant currency basis) to $418.9 million for 2022 compared to 2021. The decrease was driven by reduced spend from retail clients in the region, in particular in Japan and South-Asia, partly offset by our business in India.
 Additionally, $2,017 million of revenue for 2022 was negatively impacted by $147.6 million of currency fluctuations, particularly as a result of the depreciation of the Euro, the Japanese Yen and the British pound sterling compared to the U.S. dollar.

This decrease was primarily the result of a $(161.9) million, or (15)% decrease in traffic acquisition costs (or (14)% on a constant currency basis), partially offset by a $(26.5) million, or 20% increase in other cost of revenue.
 The decrease in Marketing Solutions' traffic acquisition costs of (12)% (or (11)% decrease on a constant currency basis) related primarily to the (13)% decrease in the average CPM for inventory purchased, including lower CPMs for signal-limited environments where Criteo continues to perform, partially offset by a 1% increase in the number of impressions we purchased, reflecting our expanding relationships with existing and new publisher partners, in particular through direct connections, to support client demand for advertising campaigns.
 Traffic acquisition costs in Retail Media decreased by (86)% reflecting the technical and transitory impact related to the client migration of our platform, as we recognize revenue on a net basis.

 The increase in other cost of revenue includes an increase in hosting costs of $27.9 million and other cost of sales of $3.7 million mostly related to Iponweb offset by a decrease of $(5.1) million in depreciation of data center servers.
 Cost of revenue for 2022 decreased $(250.5) million, or (17)%, compared to 2021. This decrease was primarily the result of a $(244.7) million, or (18)% decrease in traffic acquisition costs (or (14)% on a constant currency basis), and by a $(5.8) million, or (4)% decrease in other cost of revenue.
 The decrease in Marketing Solutions' traffic acquisition costs of (13)%, related primarily to the (25)% decrease (or (14)% decrease on a constant currency basis) in the average CPM for inventory purchased, including lower CPMs for signal-limited environments where Criteo continues to perform, partially offset by a 15% increase in the number of impressions we purchased, reflecting our expanding relationships with existing and new publisher partners, in particular through direct connections, to support client demand for advertising campaigns.
 Traffic acquisition costs in Retail Media decreased by (67)% reflecting the technical and transitory impact related to the client migration of our platform, as we recognize revenue on a net basis.
 The decrease in other cost of revenue includes a $10.2 million decrease in allocated depreciation and amortization expense and a $0.2 million in data acquisition costs, partially offset by $(3.3) million increase in hosting costs, $(1.3) million increase in other cost of sales mainly due to the digital tax and proceeds from disposal of data center equipments.

 Contribution excluding Traffic Acquisition Costs
 We define Contribution excluding Traffic Acquisition Costs, "Contribution ex-TAC", as a profitability measure akin to gross profit. It is calculated by deducting traffic acquisition costs from revenue and reconciled to gross profit through the exclusion of other costs of revenue. Contribution ex-TAC is not a measure calculated in accordance with U.S. GAAP. We have included Contribution ex-TAC because it is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions. In particular, we believe that this measure can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Contribution ex-TAC provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Contribution ex-TAC has limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) other companies, including companies in our industry which have similar business arrangements, may address the impact of TAC differently; (b) other companies may report Contribution ex-TAC or similarly titled measures but calculate them differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Contribution ex-TAC alongside our other U.S. GAAP financial measures.
 The below table provides a reconciliation of Contribution ex-TAC to gross profit:

 Gross Profit increased $67.8 million, or 9% for the twelve months ended December 31, 2023 compared to the twelve months ended December 31, 2022, and Contribution ex-TAC increased $94.4 million, or 10% for the twelve months ended December 31, 2023 compared to the twelve months ended December 31, 2022. The increase in Gross Profit and Contribution ex-TAC was primarily due to the growth in Retail Media and the contribution from Iponweb. This was partially offset by a decline in Marketing Solutions.
 Gross Profit increased $13.3 million, or 2% for the twelve months ended December 31, 2022 compared to the twelve months ended December 31, 2021, and Contribution ex-TAC increased $7.4 million, or 1% for the twelve months ended December 31, 2022 compared to the twelve months ended December 31, 2021.

 Financial and Other Income for 2023 decreased by $(20.3) million, or (114)% compared to 2022. 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, the accretion of earn-out liability related to Iponweb acquisition and financial expense relating to our 407 million available Revolving Credit Facility (RCF). At December 31, 2023, 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.
 Financial and Other Income for 2022 increased by $15.8 million, or 817% compared to 2021. 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 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.

 The provision for income taxes for 2023 decreased by $(11.1) million, or (36)%, compared to 2022, due to the non deductible loss contingency related to the CNIL matter as described in Note 20.
 The annual effective tax rate for 2023 was 26.9%, compared to an annual effective tax rate of 74.1% for 2022. The annual effective tax rate differs from the statutory rates primarily due to the impact of the domestic tax deduction applicable to technology royalty income we received from our subsidiaries, differences in tax rates in foreign jurisdictions, tax loss carryforwards in certain foreign subsidiaries, non-recognition of deferred tax assets related to tax losses and temporary differences, recognition of previously unrecognized tax losses and equity awards compensation expense.
 In 2023, our income before taxes increased by $32.7 million to $74.7 million, compared to 2022, generating a $19.3 million theoretical income tax expense at a nominal standard French tax rate of 25.82%. This theoretical tax expense is impacted mainly by the following items contributing to a $20.1 million effective tax expense and a 26.9% effective tax rate: $8.8 million of net effect of share-based compensation, $2.8 million of permanent differences mainly employee costs, $0.9 million of deferred tax assets on which we recognized a valuation allowance, offset by $4.3 million tax deduction resulting from technology royalty income we received from our subsidiaries, $5.5 million resulting from the non-tax deductible provision following the loss contingency on regulatory matters (refer to Note 20), and the recognition or reversal of valuation allowance on deferred tax assets of $1.8 million. Please see Note 18 to our audited consolidated financial statements for more detailed information on the provision for income taxes.
 Amounts recognized in our Consolidated Financial Statements are calculated at the level of each subsidiary within our Consolidated Financial Statements.
 As at December 31, 2023, 2022 and 2021, the valuation allowance against net deferred income taxes amounted to $29.8 million, $31.1 million and $35.0 million, which related mainly to Criteo Corp. ($5.7 million, $5.7 million and $5.7 million, respectively), Criteo Brazil ($2.7 million, $3.3 million and $2.7 million, respectively), Criteo Ltd ($10.7 million, $8.1 million and $7.6 million, respectively), Criteo Singapore ($1.2 million, $1.5 million and $4.2 million), Criteo Pty ($2.9 million, $2.6 million and $2.7 million) and Criteo France ($5.0 million, $6.5 million and $6.2 million, respectively).

 The provision for income taxes for 2022 increased by $15.0 million, or 93%, compared to 2021, due to the non deductible loss contingency related to the CNIL matter as described in Note 20.
 The annual effective tax rate for 2022 was 74.1%, compared to an annual effective tax rate of 10.5% for 2021. The annual effective tax rate differs from the statutory rates primarily due to the impact of the domestic tax deduction applicable to technology royalty income we received from our subsidiaries, differences in tax rates in foreign jurisdictions, tax loss carryforwards in certain foreign subsidiaries, non-recognition of deferred tax assets related to tax losses and temporary differences, recognition of previously unrecognized tax losses and equity awards compensation expense.

 In 2022, our income before taxes decreased by $111.8 million to $42.1 million, compared to 2021, generating a $10.9 million theoretical income tax expense at a nominal standard French tax rate of 25.82%. This theoretical tax expense is impacted mainly by the following items contributing to a 31.2 million effective tax expense and a 74.1% effective tax rate: $1.7 million of deferred tax assets on which we recognized a valuation allowance, $16.9 million resulting from the non-tax deductible provision following the loss contingency on regulatory matters (refer to Note 20), $6.2 million of permanent differences (mainly employee costs and intercompany transactions), $1.6 million related to the French business tax, Cotisation sur la Valeur Ajout e des Entreprises, or "CVAE", and $2.9 million of net effect of share-based compensation offset by a $6.7 million tax deduction resulting from technology royalty income we received from our subsidiaries, $2.9 million Research and Development tax credit in France, and the recognition or reversal of valuation allowance on deferred tax assets of $1.3 million. Please see Note 18 to our audited consolidated financial statements for more detailed information on the provision for income taxes.
 Amounts recognized in our Consolidated Financial Statements are calculated at the level of each subsidiary within our Consolidated Financial Statements. As at 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).

 We define Adjusted EBITDA as our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, certain acquisition costs and a loss contingency related to a regulatory matter. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. We have included Adjusted EBITDA because it is a key measure used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short-term and long-term operational plans. In particular, we believe that the elimination of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, certain acquisition costs and a loss contingency related to a regulatory matter in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are: (a) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; (b) Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (c) Adjusted EBITDA does not reflect the potentially dilutive impact of equity-based compensation; (d) Adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us; and (e) other companies, including companies in our industry, may calculate Adjusted EBITDA or similarly titled measures differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider Adjusted EBITDA alongside our U.S. GAAP financial results, including net income.

 Net income increased $43.8 million, or 402% for the twelve months ended December 31, 2023 compared to the twelve months ended December 31, 2022, and Adjusted EBITDA increased $34.5 million, or 13% for the twelve months ended December 31, 2023 compared to the twelve months ended December 31, 2022. The increase in Net Income and Adjusted EBITDA was primarily due to higher Contribution ex-TAC, cost reduction actions and less income taxes, and by higher Contribution ex-TAC and cost reductions actions, respectively.

 Net income decreased $(126.8) million, or (92)% for the twelve months ended December 31, 2022 compared to the twelve months ended December 31, 2021, and Adjusted EBITDA decreased $(55.2) million, or (17)% for the twelve months ended December 31, 2022 compared to the twelve months ended December 31, 2021. The decrease in Net Income was primarily due to the CNIL penalty and increased income taxes offset by financial income. The adjusted EBITDA decrease was mainly due to our Iponweb acquisition.

 B. Liquidity and Capital Resources.
 Market Risk
 We are mainly exposed to changes of foreign currency exchange rate fluctuations.
 The functional currency of the Company is the euro, while our reporting currency is the U.S. dollar. Because we incur some of our expenses and derive revenues in currencies other than the euro, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. Foreign exchange risk exposure also arises from intra-company transactions and financing with subsidiaries that have a functional currency different than 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 statement of income, statement of comprehensive income and statement 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" in the Consolidated Statement of Changes in Equity.
 Since 2013, the Company has had a foreign currency risk management policy in place. At December 31, 2023, 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.

 Counterparty Risk
 As of December 31, 2023, we show a positive net cash position. We utilize cash pooling arrangements, reinforcing cash management centralization. Investment and financing decisions are governed by our Investment and Risk Management Policy and carried out by our internal central treasury function, ensuring investments are entered into with high credit ratings, balanced counterparties.

 Liquidity Risk
 We are mainly exposed to changes of foreign currency exchange rate fluctuations.
 Sources of Liquidity
 Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations. We have never declared or paid any cash dividends on our ordinary shares. We do not anticipate paying cash dividends on our equity securities in the foreseeable future.
 We are party to a loan agreement and several RCFs with third-party financial institutions. Our loan and RCF agreements as of December 31, 2023 are presented in the table below:

 For additional information regarding our RCF agreement, please refer to Note 11 - Financial Liabilities and Note 20 - Commitments.
 This RCF is unsecured and contain customary events of default and covenants, including compliance with a total net debt to adjusted EBITDA ratio and restrictions on the incurrence of additional indebtedness. At December 31, 2023, we were in compliance with the leverage ratio.
 We are also party to short-term credit lines and overdraft facilities with HSBC Holdings plc, LCL and BNP Paribas. We are authorized to draw up to a maximum of 21.5 million ($23.8 million) in the aggregate under those short-term credit lines and overdraft facilities. As of December 31, 2023, we had not drawn on either of these facilities. Our banks have the ability to terminate such facilities on short notice.
 Our cash and cash equivalents and restricted cash at December 31, 2023 were held for working capital and general corporate purposes, which could include acquisitions, and amounted to $411.3 million as of December 31, 2023. The $(36.9) million decrease in cash and cash equivalents compared with December 31, 2022 primarily resulted from a decrease of $(31.7) million in cash from operating activities and a $57.4 million decrease in cash used for investing activities, partially offset by an increase of $34.2 million in cash used for financing activities. In addition, the cash flows were also negatively impacted by $(5.2) million due to foreign exchange rates impact on our consolidated cash position in USD over the period. We do not enter into investments for trading or speculative purposes. Our policy is to invest any cash in excess of our immediate requirements in investments designed to preserve the principal balance and provide liquidity. Accordingly, our cash and cash equivalents are invested primarily in demand deposit accounts and term deposit accounts.
 Furthermore, Criteo had financial liquidity of approximately $837.4 million, including its cash position, short term investments, its Revolving Credit Facility and treasury shares available for acquisitions as of December 31, 2023. Overall, we believe that our current financial liquidity, combined with our expected cash-flow generation in 2023, enables financial flexibility and the meeting of all material contractual obligations.
 We have also reserved $75 million in cash (classified as Restricted cash on our Consolidated Statements of Financial Position) to fund the earn-out liability obligations, resulting from the Iponweb acquisition (refer to Note 2).
 Share Buy-back Programs
 In December 2021, we completed a $100 million share repurchase program. In 2022, we completed an additional $136 million share repurchase, and in 2023, we completed an additional $125 million share repurchase program.

 All above programs have been implemented under our multi-year authorization granted by Board of Directors. On February 1, 2024, this authorization was extended to a total amount of $630 million. Other than these repurchase programs, we intend to retain all available funds and any future earnings to fund our growth.
 Operating and Capital Expenditure Requirements
 In 2023, 2022 and 2021, our actual capital expenditures were $114.3 million, $55.8 million and $53.0 million, respectively, primarily related to the acquisition of data center and server equipment, and internal IT systems. We expect our capital expenditures to remain at, or slightly below, 5% of revenue for 2024, as we plan to continue to build, reshape and maintain additional data center equipment capacity in all regions and increase our investments supporting our new work from home policy as part of our office right sizing program.
 On March 2023, we acquired all of the outstanding shares of Brandcrush Pty Ltd. In 2022 we entered into a definitive purchase agreement which resulted in the Iponweb acquisition for $(135.5) million of cash consideration paid. In 2021 we acquired all of the outstanding shares of Doobe In Site Ltd. ("Mabaya"), financed by available cash resources.
 We believe our existing cash balances will be sufficient to meet our anticipated cash requirements through at least the next 12 months.
 Our future working capital requirements will depend on many factors, including the rate of our revenue growth, the amount and timing of our investments in personnel and capital equipment, and the timing and extent of our introduction of new products and product enhancements.
 If our cash and cash equivalents balances and cash flows from operating activities are insufficient to satisfy our liquidity requirements, we may need to raise additional funds through equity, equity-linked or debt financings to support our operations, and such financings may not be available to us on acceptable terms, or at all. We may also need to raise additional funds in the event we determine in the future to effect one or more acquisitions of businesses, technologies, assets or products.
 If we are unable to raise additional funds when needed, our operations and ability to execute our business strategy could be adversely affected. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to holders of our equity securities and could contain covenants that restrict our operations. Any additional equity financing will be dilutive to our shareholders.

 Our cash and cash equivalents at December 31, 2023 were held for working capital and general corporate purposes, which could include acquisitions. The decrease in cash and cash equivalents compared with December 31, 2022, primarily resulted from an increase of $224.2 million in cash flows from operating activities fully offset by a decrease of $(108.7) million in cash flows used for investing activities and a decrease of $(147.3) million in cash flows used for financing activities.
 Operating Activities
 Cash provided by operating activities is primarily impacted by the increase in the number of clients using our solution and by the amount of cash we invest in personnel to support the anticipated growth of our business.

 Cash provided by operating activities has typically been generated from net income and by changes in our operating assets and liabilities, particularly in the areas of accounts receivable and accounts payable and accrued expenses, adjusted for certain non-cash and non-operating expense items such as depreciation, amortization, equity awards compensation, deferred tax assets and income taxes.
 In 2023, net cash flows provided by operating activities were $224.2 million and consisted of net income of $54.6 million, $103.4 million in adjustments for non-cash and non-operating items and $66.2 million of cash flows from working capital. Adjustments for non-cash and non-operating items mainly consisted of depreciation and amortization expense of $72.3 million, equity awards compensation expense of $97.2 million, partially offset by a $(43.3) million payment of a contingent liability for regulatory matters. In 2023, our cash generated by operating activities benefited from strong working capital leverage.
 The $66.2 million increase in cash resulting from changes in working capital primarily consisted of a $(0.7) million decrease due to changes in operating lease liabilities and right of use assets, a $(8.5) million increase in other current assets (including prepaid expenses and VAT receivables) and a $(56.3) million increase in accounts receivable partially offset by a $43.8 million increase in accrued expenses such as payroll and payroll related expenses and VAT payables and a $87.9 million increase in accounts payable. The increase in accounts receivable and in accounts payable is mainly due to seasonality.
 In 2022, net cash flows provided by operating activities were $256.0 million and consisted of net income of $10.9 million, $185.0 million in adjustments for noncash and non-operating items and $60.1 million of cash flows from working capital. Adjustments for non-cash and non-operating items primarily consisted of depreciation and amortization expense of $150.3 million, equity awards compensation expense of $65.0 million, changes in deferred tax assets of $3.6 million, partially offset by $(11.0) million of accrued income taxes net of income tax paid and $(22.9) million of other non-cash and non-operating items. In 2022, our cash generated by operating activities benefited from strong working capital leverage, largely due to the impact from strong collections, in particular Iponweb, which has favorable seasonality in the fourth quarter.
 The $60.1 million increase in cash resulting from changes in working capital primarily consisted of a $0.7 million decrease due to changes in operating lease liabilities and right of use assets, a $(14.7) million increase in other current assets (including prepaid expenses and VAT receivables) and a $(41.9) million increase in accounts receivable partially offset by a $(17.9) million decrease in accrued expenses such as payroll and payroll related expenses and VAT payables and a $133.8 million increase in accounts payable mainly due to seasonality.
 In 2021, net cash flows provided by operating activities were $220.9 million and consisted of net income of $137.6 million, $124.9 million in adjustments for non-cash and non-operating items and $(41.6) million of cash flows from working capital. Adjustments for non-cash and non-operating items primarily consisted of depreciation and amortization expense of $90.9 million, equity awards compensation expense of $44.5 million, changes in deferred tax assets of $(18.6) million, $2.0 million generated on disposal of non-current assets, and by $6.0 million of accrued income taxes net of income tax paid.
 The $(41.6) million decrease in cash resulting from changes in working capital primarily consisted of a $(2.6) million decrease due to changes in operating lease liabilities and right of use assets, a $(19.7) million increase in other current assets (including prepaid expenses and VAT receivables) and a $(135.0) million increase in accounts receivable partially offset by a $33.6 million increase in accrued expenses such as payroll and payroll related expenses and VAT payables and $82.7 million increase in accounts payable.

 Investing Activities
 Our investing activities to date have consisted primarily of purchases of servers and other data-center equipment and business acquisitions.
 In 2023, net cash flows used in investing activities were $108.7 million and consisted of $114.3 million for purchases of servers and other data-center equipment and capitalized software development costs, $6.8 million payment for a business acquisition, partially offset by a $3.6 million change in other non-current financial assets resulting from investments in Marketable Securities (see Note 4), and $8.8 million in proceeds from the sale of a non consolidated investment.
 In 2022, net cash flows used in investing activities were $166.1 million and consisted of $55.8 million for purchases of servers and other data-center equipment and capitalized software development costs, $138.0 million for business acquisitions and $27.8 million change in other non-current financial assets resulting from investments in Marketable Securities (see Note 5).
 In 2021, net cash flows used in investing activities were $76.4 million and consisted of $53.0 million for purchases of servers and other data-center equipment and capitalized software development costs, $10.4 million for business acquisitions and $12.9 million change in other non-current financial assets resulting from investments in Marketable Securities (see Note 5).

 Financing Activities
 In 2023, net cash used in financing activities was $147.3 million mainly resulting from the $125.5 million impact from our share repurchase program, a $(22.0) million payout of the current portion of the earn-out liability resulting from the Iponweb Acquisition, partially offset by $1.9 million in proceeds from stock-options exercises.
 In 2022, net cash used in financing activities was $113.0 million mainly resulting from the $135.7 million impact from our share repurchase program, partially offset by $21.9 million change relating to the recognition of a positive impact of foreign exchange reevaluations net of related hedging and $1.0 million in proceeds from stock-options exercises.
 In 2021, net cash used in financing activities was $80.1 million mainly resulting from the $25.2 million proceeds from stock-options exercises and the $100.0 million impact from our share repurchase program.

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

 D. Tabular Disclosure of Contractual Obligations.
 Our principal commitments consist of non-cancelable operating leases for our various office facilities and data centers, and other contractual commitments consisting of obligations to our hosting services providers, and providers of software as a service.
 The following table discloses aggregate information about material contractual obligations and periods in which payments were due as of December 31, 2023. Future events could cause actual payments to differ from these estimates.

 Material Cash Requirements
 We currently anticipate that our available funds and cash flow from operations and financing activities will be sufficient to meet our operational cash needs and fund our share repurchase program for at least the next 12 months and thereafter for the foreseeable future. We continuously evaluate our liquidity and capital resources, including our access to external capital, to ensure we can finance our future capital requirements.
 Leases and Contractual Commitments
 Our operating lease obligations mostly include offices and data centers. Our finance lease obligations mostly include certain network infrastructure. Our restructuring efforts to sublease, early terminate or abandon several office buildings under operating leases did not materially change our operating lease obligations.
 Our contractual commitments are primarily related to our investments in network infrastructure, servers, and consumer hardware products in Reality Labs.
 Contingent Consideration
 As part of the Iponweb Acquisition that was completed in August 2022, the Sellers are entitled to contingent consideration of a maximum of $ 100.0 million, which is conditioned upon the achievement of certain revenue targets by the Iponweb business for the 2022 and 2023 fiscal years. The related earn out liability is valued and discounted using management's best estimate of the consideration that will be paid in 2024 (current portion). See Note 13 - Other Current Liabilities.
 Contingencies
 We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations. We record a liability when we believe that it is both probable that a liability has been incurred, and that 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 estimated, we disclose the possible loss in the accompanying notes to the consolidated financial statements to the extent material. Significant judgment is required to determine both probability and the estimated amount of loss. Such matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond our control. Should any of these estimates and assumptions change or prove to be incorrect, it could have a material impact on our results of operations, financial position, and cash flows.
 See 12. Leases, 13. Other Current Liabilities and Non Current Liabilities, 20. Commitments and contingencies, and 18. Income Taxes in the notes to the consolidated financial statements included in Part II, Item 8, and "Legal Proceedings" contained in Part I, Item 3 of this Form 10-K for additional information regarding leases and contractual commitments, long-term debt, taxes, and contingencies.

 E. Trend Information
 Key Metrics
 We review three key metrics to help us monitor the performance of our business and to identify trends affecting our business. These key metrics include number of clients, Contribution ex-TAC, and Adjusted EBITDA. We believe these metrics are useful to understanding the underlying trends in our business. The following table summarizes our key metrics for 2023, 2022 and 2021.

 (1) In the first quarter of 2023, we streamlined our client count methodology which is now based on unique billing accounts while the previous methodology included clients from whom Criteo has received a signed contract or an insertion order during the previous 12 months. The new methodology led to the consolidation of some clients accounts but does not change the underlying activity or the overall trends.
 Number of Clients
 We define a client to be a unique party from whom we have received a signed contract or an insertion order and for whom we have delivered an advertisement or monetized an advertising inventory during the previous 12 months. We believe this criteria best identifies clients who actively use our set of solutions. We count specific brands or divisions within the same business as distinct clients so long as those entities have separately signed insertion orders with us. In the case of some solutions within Criteo Retail Media, we count the parent company of the brands as an individual client, even if several distinct brands pertaining to the same parent company have signed separate contracts or insertion orders with us. On the other hand, we count a client who runs campaigns in multiple geographies as a single client, even though multiple insertion orders may be involved. When the insertion order is with an advertising agency, we generally consider the client on whose behalf the advertising campaign is conducted as the "client" for purposes of this calculation. In the event a client has its advertising spend with us managed by multiple agencies, that client is counted as a single client.
 We believe that our ability to increase the number of clients is an important indicator of our ability to grow revenue over time. While our client count has increased over time, this metric can also fluctuate from quarter to quarter due to the seasonal trends in advertising spend of clients and the timing and amount of revenue contribution from new clients. Therefore, there is not necessarily a direct correlation between a change in clients in a particular period and an increase or decrease in our revenue over that same period.

 We define Contribution excluding Traffic Acquisition Costs, "Contribution ex-TAC", as a profitability measure akin to gross profit. It is calculated by deducting traffic acquisition costs from revenue and reconciled to gross profit through the exclusion of other cost of revenue. Contribution ex-TAC is not a measure calculated in accordance with U.S. GAAP. Contribution ex-TAC because it is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions. In particular, we believe that this measure can provide useful measures for period-to-period comparisons of our business. Accordingly, we believe that Contribution ex-TAC provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Please see above for a discussion of the limitations of Contribution ex-TAC and a reconciliation of Contribution ex-TAC to gross profit, the most comparable U.S. GAAP measure in the Non-GAAP Financial Measures section of this filing.
 Our management views our Contribution ex-TAC as a key measure to evaluate, plan and make decisions on our business activities and sales performance. In particular, we believe this can provide a useful measure for period-to-period comparisons of our business. Accordingly, we believe that Contribution ex-TAC provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Contribution ex-TAC is not a measure calculated in accordance with U.S. GAAP. Please see above for a discussion of the limitations of Contribution ex-TAC and a reconciliation of Contribution ex-TAC to gross profit, the most comparable U.S. GAAP measure, for 2022 and 2023.
 Adjusted EBITDA represents our consolidated earnings before financial income (expense), income taxes, depreciation and amortization, adjusted to eliminate the impact of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, certain acquisition costs and a loss contingency related to a regulatory matter. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. Adjusted EBITDA is a key measure used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short-term and long-term operational plans. In particular, we believe that the elimination of equity awards compensation expense, pension service costs, certain restructuring, integration and transformation costs, certain acquisition costs and a loss contingency related to a regulatory matter in calculating Adjusted EBITDA can provide a useful measure for period-to-period comparisons of our business,
 Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations in the same manner as our management and board of directors. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP.

 Highlights and Trends
 Number of Clients
 Since our inception, we have significantly grown the number of clients with which we do business. We had approximately 18,200 clients as of December 31, 2023, down slightly compared to our client base as of December 31, 2022.
 In recent years, the expansion of our clients has been driven our global footprint and our commercial expansion in existing markets, our continued development of large clients in the Retail vertical, especially in ecommerce, our expansion of midmarket clients and our penetration into the consumer brand vertical through some of our Criteo Retail Media offerings. We expect to continue to focus our attention and investment on further growing our client base across all regions, client categories and verticals, with continued strong focus on ecommerce.

 Client Retention
 We believe our ability to retain and grow revenue from our existing clients is a useful indicator of the stability of our revenue base and the long-term value of our client relationships. Our offering, the Criteo Commerce Media Platform, is powered by AI technology and aims to cover the entire marketing funnel (Awareness, Audience Targeting, Conversion). Our technology is optimized to drive impactful business outcomes from marketing and monetization for retailers and brands. We measure our client satisfaction through our ability to retain them and the revenue they generate quarter after quarter.
 We define client retention rate as the percentage of live clients during the previous quarter that continued to be live clients during the current quarter. This metric is calculated on a quarterly basis, and for annual periods, we use an average of the quarterly metrics. We define a live client as a client whose advertising campaign has or had been generating revenue for us on any day over the relevant measurement period. In each of 2023, 2022 and 2021, our client retention rate was approximately 90%.
 Seasonality
 Our client base consists primarily of businesses in the digital Retail, Travel and Classifieds industries, which we define as commerce clients. In the digital Retail industry and the consumer brand verticals in particular, many businesses devote the largest portion of their advertising spend to the fourth quarter of the calendar year, to coincide with increased holiday spending by consumers. With respect to Criteo Retail Media and Iponweb, the concentration of advertising spend in the fourth quarter of the calendar year is particularly pronounced. Our Retail clients typically conduct fewer advertising campaigns in the first and second quarters than they do in other quarters, while our Travel clients typically increase their travel campaigns in the first and third quarters and conduct fewer advertising campaigns in the second quarter. As a result, our revenue tends to be seasonal in nature, but the impact of this seasonality has, to date, been partly offset by our significant growth and geographic expansion. If the seasonal fluctuations become more pronounced, our operating cash flows could fluctuate materially from period to period.
 Our Contribution ex-TAC for 2023 was 1,022.6 million, a 11% increase over 2022, at constant currency. This performance was mainly driven by growth in Retail Media and the contribution from Iponweb. We are focused on maximizing our Contribution ex-TAC on an absolute basis. We believe this focus builds sustainable long-term value for our business by fortifying a number of our competitive strengths, including access to digital advertising inventory, breadth and depth of data and continuous improvement of the Criteo AI Engine's performance, allowing us to deliver more relevant advertisements at scale.
 Our Adjusted EBITDA for 2023 was $301.8 million, a 13% increase over 2022. Our increase in Adjusted EBITDA for 2023 compared to 2022 was primarily the result of the 10% increase in Contribution ex-TAC over the period, partly offset by a 5% increase in our Non-GAAP operating expenses. This drove a 30% adjusted EBITDA margin in 2023. We delivered $70 million in cost savings, while continuing to invest for growth, which drove a higher Adjusted EBITDA margin as a percentage of Contribution ex-TAC compared to 2022. Going forward, we intend to continue to right size our organization and optimize our operating model while continuing investments in our multi-pronged addressability strategy and scaling Retail Media capabilities. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. Please see above for a discussion of the limitations of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, the most comparable U.S. GAAP measure.

 We are mainly exposed to changes of foreign currency exchange rate fluctuations.
 For a description of our foreign exchange risk and a sensitivity analysis of the impact of foreign currency exchange rates on our net income, please see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – B. Liquidity and Capital Resources" in this Form 10-K.

 Item 8. Financial Statements and Supplementary Data
 The information required by Item 8 is set forth on pages F-1 through F-46 of this Form 10-K.

 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
 There have been no changes in our independent registered public accounting firm, Deloitte & Associ s, or disagreements with our accountants on matters of accounting and financial disclosure.

 Item 9A. Controls and Procedures
 Evaluation of Disclosure Controls and Procedures
 Criteo carried out an evaluation as of December 31, 2023, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Disclosure controls and procedures are controls and other procedures designed to reasonably assure that information required to be disclosed in our reports filed or furnished under the Exchange Act, such as this Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.
 Disclosure controls and procedures are also designed to reasonably assure that this information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure.
 Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2023, our disclosure controls and procedures were effective to provide reasonable assurance.

 Management's Annual Report on Internal Control Over Financial Reporting
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our management assessed, with the oversight of our board of directors, the effectiveness of our internal control over financial reporting as of December 31, 2023. In making this assessment, our management used the criteria established in the Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2023. The effectiveness of the Company's internal control over financial reporting as of December 31, 2023 has been audited by Deloitte & Associ s, our independent registered public accounting firm, as stated in its attestation report, which appears on page F-2 of this Form 10-K.

 Changes in Internal Control Over Financial Reporting
 There were no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the quarter ended December 31, 2023, that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
 Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Criteo have been detected.

 These inherent limitations include the realities that judgments in decisions making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies and procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the shareholders and the Board of Directors of Criteo S.A.

 Opinion on the Financial Statements

 We have audited the accompanying consolidated statements of financial position of Criteo S.A. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

 Basis for Opinion

 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

 Critical Audit Matter

 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which is relates.

 Revenue — Refer to Note 1 to the financial statements

 Critical Audit Matter Description

 The Company's revenue from Marketing Solutions consists of delivering personalized display advertisements featuring product-level recommendations either directly to clients or to advertising agencies. Such products are generally sold based on a cost-per-click or cost-per-impression pricing models.

 Revenues for Marketing Solutions are recognized when an ad is clicked on or displayed to the end user as that is when the Company transfers control of promised services directly to the Company's clients in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those services. The cost-per-click or cost-per-impression the Company charges to the customers, varies depending on the optimization strategy of the Criteo engine, the dynamics and performance of the market, amongst other factors. Because of the nature of the Company's revenue, which is made up of a significant volume of low-dollar value transactions, sourced from multiple databases and other tools, the Company uses highly automated systems to process and record its revenue transactions.

 We identified revenue for Marketing Solutions as a critical audit matter because the Company's systems to process and record its revenue transactions are highly automated and thus required significantly more involvement and effort from our information technology (IT) internal specialist team to identify, test, and evaluate the Company's system, software applications, and automated controls.

 How the Critical Audit Matter Was Addressed in the Audit

 With the assistance of our IT specialists and Data specialists, our audit procedures related to the Company's system to process and record its revenue transactions included the following:

 • Identified the relevant applications and systems used to process revenue transactions and tested the general IT controls over these applications and systems, including testing of user access controls, change management controls, and Datacenter and Network Operations.

 • Performed testing of system interface controls and automated controls within the relevant revenue solutions, as well as the controls designed to address the occurrence, accuracy and completeness of revenue.

 • Tested internal controls within the revenue business process, including those in place to reconcile the various applications to the Company's general ledger.

 • Tested the underlying data of the revenue transactions by agreeing the events recognized in the financial statements to the source transactional systems and tested the mathematical accuracy of the recorded revenue.

 We have served as the Company's auditor since 2011.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the shareholders and the Board of Directors of Criteo S.A.

 Opinion on Internal Control over Financial Reporting

 We have audited the internal control over financial reporting of Criteo S.A. and subsidiaries (the "Company") as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 23, 2024, expressed an unqualified opinion on those financial statements.

 Basis for Opinion

 The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

 Definition and Limitations of Internal Control over Financial Reporting

 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 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
 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) 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.
 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 and nine years. 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 business climate indicate that the carrying amount of an asset may be impaired.
 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. Management determines the appropriate useful life of property, plant 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.
 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 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.
 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.
 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.
 We apply 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, we use 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. 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, 2023 an individual customer accounted for 10% or more of accounts receivable. As of December 31, 2022, no individual customer accounted for more than 10% of accounts receivable. During the years ended December 31, 2023, 2022 and 2021, 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 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 space 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 have multiple pricing models which include percentage of spend models, as well as cost-per-click, and cost-per-impression pricing models.
 Cost-per-click 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, 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, as we consider the delivery of clicks 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 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 primarily as principal in our Marketing Solutions segment 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 primarily as principal for our Criteo Marketing Solutions engagements and accordingly report the revenue earned and related costs incurred on a gross basis.
 We act primarily as agent in our 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 segment 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.
 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 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.
 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 consist primarily of purchases of impressions from publishers on a CPM basis, incurred to generate our revenues, primarily for the Marketing Solutions 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.
 For a discussion of the trends we expect to see in traffic acquisition costs, see the section entitled " - Highlights and Trends - Contribution ex-TAC" in Item 7.D -Trend Information below.
 Other Cost of Revenue. Other cost of revenue includes expenses related to third-party hosting fees, depreciation of data center equipment, the cost of 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.
 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 of $ 1.7 million, $ 7.6 million, and $ 2.5 million for the years ended December 31, 2023, 2022, and 2021, respectively.
 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 trued up based on 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.
 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, Cr dit d'Imp t 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, 2023, we have offset $ 9.5 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&D performed in the U.S. for purposes of the U.S. Research Tax Credit.
 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.
 Operating Segments
 We report our financial results based on three reportable segments: Marketing Solutions, Retail Media and Iponweb.
 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 ("CODM") in deciding how to allocate resources and assessing performance.
 Our CODM is our CEO.
 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

 Accounting Pronouncements adopted in 2023

 No standards were adapted in 2023 which had a material impact on the Company's financial statements.
 Recent Accounting Pronouncements

 In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, a final standard on improvements to 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 standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. This accounting standard is effective in the first quarter of the Company's fiscal year ended December 31, 2025. We are currently evaluating the impact of adoption on our financial disclosures.
 In November 2023, the FASB issued 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 update is required to be applied retrospectively to prior periods presented, based on the significant segment expense categories identified and disclosed in the period of adoption. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact of adoption on our financial disclosures.
 Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's Consolidated Financial Statements upon adoption.

 Note 2. Business Combinations
 Brandcrush

 On February 28, 2023, we completed the acquisition of all of the outstanding shares of Brandcrush Pty Ltd. ("Brandcrush"). The purchase price for the acquisition of shares was $ 7.1 million. The acquisition was financed by available cash resources. The transaction has been accounted for as a business combination under the acquisition method of accounting. The purchase price allocation has been completed and resulted in the recognition of intangible assets related to technology of $ 3.5 million and goodwill of $ 5.0 million. In addition, acquisition costs amounting to $ 0.7 million were fully expensed as incurred.

 On August 1, 2022 (the "Acquisition Date"), the Company entered into an amended and restated Framework Purchase Agreement (the "FPA"), 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 (the "Iponweb Acquisition").

 The purchase price, as per ASC 805, was $ 290.2 million 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. See Note 13 for further details.

 The Company transferred Treasury shares with a fair value of $ 70.2 million to Iponweb's Sellers, subject to lock-up conditions. See Note 16 for further details.

 The transaction was accounted for as a business acquisition. The purchase price allocation has been completed and resulted in recognition of $ 187.6 million of goodwill.

 Note 4. 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. For the year ended December 31st, 2023, the Company reported 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.

 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 does not review any other financial information for our three segments, other than Contribution ex-TAC.

 September 2027

 On September 27, 2022, we entered into a new Revolving Credit Facility ("RCF") with a five year tenor with a syndicate of banks which allows us to draw up to 407 million ($ 450 million).
 On November 17, 2023, we updated certain terms of our 407 million ($ 450 million) syndicated credit facility to a 407 million ($ 450 million) sustainability-linked credit facility, the framework for which was provided for in the initial credit facility agreement. Certain terms and conditions of the amended credit facility are now linked to our sustainability goals to increase the representation of women in tech roles and reduce our GHG emissions, while the rest of the credit facility agreement remains unchanged.

 We are also party to short-term credit lines and overdraft facilities with HSBC plc, BNP Paribas and LCL with an authorization to draw up to a maximum of 21.5 million ($ 23.8 million) in the aggregate under the short-term credit lines and overdraft facilities. As of December 31, 2023, we had not drawn on any of these facilities. Any loans or overdrafts under these short-term facilities bear interest based on the one month EURIBOR rate or three month EURIBOR rate. As these facilities are exclusively short-term credit and overdraft facilities, our banks have the ability to terminate such facilities on short notice.
 At December 31, 2023, no amount is drawn under the RCF.
 This revolving credit facilities is unsecured and contain customary events of default and covenants, including compliance with a total net debt to adjusted EBITDA ratio and restrictions on the incurrence of additional indebtedness. At December 31, 2023, we were in compliance with the required leverage ratio.

As of December 31, 2023, there is no unrecognized stock-based compensation expense related to unvested stock options.

 Lock up shares

 On August 1, 2022, 2,960,243 Treasury shares were transferred to the Founder (referred to as Lock Up Shares or "LUS"), as partial consideration for the Iponweb Acquisition. As these shares are subject to a lock-up period that expires in three installments on each of the first three anniversaries of the Iponweb Acquisition, unless the Founder's employment agreement is terminated under certain circumstances during the pendency of such lock-up period, they are considered as equity settled share-based payments under ASC 718 and are accounted over the three-year vesting period. The share based compensation expense is included in Research and Development expenses on the Consolidated Statement of Income. The shares were valued based on the volume weighted average price of one ADS traded on Nasdaq during the twenty ( 20) trading days immediately preceding July 28, 2022.

 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 Revolving Credit Facility (RCF). At December 31, 2023, our exposure to foreign currency risk was centralized at Criteo S.A. and hedged using foreign currency swaps or forward purchases or sales of foreign currencies.
 The $ 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 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.

 (1) Includes Section 174 expense capitalization
 Amounts recognized in our Consolidated Financial Statements are calculated at the level of each subsidiary within our Consolidated Financial Statements. As of December 31, 2023, 2022 and 2021, the valuation allowance against net deferred income taxes amounted to $ 29.8 million, $ 31.1 million and $ 35.0 million, which related mainly to Criteo Corp. ($ 5.7 million, $ 5.7 million and $ 5.7 million, respectively), Criteo Brazil ($ 2.7 million, $ 3.3 million and $ 2.7 million, respectively), Criteo Ltd ($ 10.7 million, $ 8.1 million and $ 7.6 million, respectively), Criteo Singapore ($ 1.2 million, $ 1.5 million and $ 4.2 million), Criteo Pty ($ 2.9 million, $ 2.6 million and $ 2.7 million) and Criteo France ($ 5.0 million, $ 6.5 million and $ 6.2 million, respectively).
 The Company mainly has net operating loss carryforwards in the U.S. for $ 34.5 million in various states, which begin to expire in 2031 and net operating loss carryforwards in the United Kingdom for $ 37.7 million which have no expiration date. The company has $ 5.7 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, 2023, 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.

 Uncertain Tax Positions
 The following table summarizes the activity related to our gross unrecognized tax benefits during the years ended December 31, 2023 2022 and 2021:

 The total amount of gross unrecognized tax benefits, including related interest and penalties, was $ 16.8 million as of December 31, 2023. 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.
 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

 On October 8, 2021, the Organization for Economic Co-operation and Development (OECD) announced the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting which agreed to a two-pillar solution to address tax challenges arising from digitalization of the economy. On December 20, 2021, the OECD released Pillar Two Model Rules ("Pillar Two") 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. Additional "top-up" tax will be due, either at domestic level ("Qualified Minimum Domestic Top-Up Tax", or under Pillar Two computation. Various foreign jurisdictions have already enacted Pillar Two implementation in domestic laws and some other are in the process of doing it as from 2024. We are currently evaluating the potential impacts on future periods of Pillar Two, based on domestic implementation laws already adopted, new laws to come and local administrative guidelines to be issued.

 Note 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.

 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, 2023, 2022 and 2021. Consequently all potential dilutive effects from shares are considered.
 For each period presented, a contract to issue a certain number of shares (i.e., share option, 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).

 Note 20. Commitments and contingencies
 Contractual Commitments
 We have $ 65.0 million of non-cancelable contractual commitments as of December 31, 2023, 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, 2023 (in millions):

 $

 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 Regulatory 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 Libert s (the "CNIL") opened a formal investigation in January 2020 against Criteo. In June 2023, the CNIL issued its decision, which retained alleged GDPR violations but reduced the financial sanction against Criteo from the original amount of 60.0 million ($ 65.0 million) to 40.0 million ($ 43.3 million). Criteo made the required sanction payment in 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 Conseil d'Etat.
 The 40.0 million ($ 43.3 million) penalty was applied against the previously accrued liability for loss contingency reflected in our financial statements for the period ended June 30, 2022, which amounted to 60.0 million ($ 65.0 million). Criteo issued the required sanction payment during the third quarter of 2023.

 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.

 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. 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 non current assets" on the consolidated statement of financial position.

 Note 22. Subsequent Events
 Beginning in the first quarter of 2024 – following the completion of the integration of our Iponweb acquisition – our Chief Operating Decision Maker, who is our Chief Executive Officer ("CEO"), no longer receives disaggregated information for Iponweb. As such, we will update our segment financial reporting structure in line with how our CEO assesses performance and allocates resources. We will have two segments: Retail Media and Performance Media. Performance Media combines our former Marketing Solutions and Iponweb segments.
