RISK FACTORS

You should carefully consider the risks described below before making an investment decision. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition or results of operations could be materially and adversely affected by any of these risks. The trading price and value of our Class A ordinary shares could decline due to any of these risks, and you may lose all or part of your investment. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus.

RISKS RELATED TO OUR BUSINESS AND INDUSTRY

The markets for our solution suites are rapidly evolving and may decline or experience limited growth.

The industry in which we operate is characterized by rapid technological change, new features, tools, solutions and strategies, evolving legal and regulatory requirements, changing customer needs and a dynamic competitive market. Our future success will depend in large part on the continued growth of our markets and our ability to improve and expand our solutions to respond quickly and effectively to this growth.

The opportunities provided by apps, mobile gaming, mobile advertising and other engagement touchpoints in mobile devices are still relatively new, and our customers, who include mobile game and app developers, advertising networks, telecom operators and OEMs, may not recognize the need for, or benefits of, some or all of our solution suites. Moreover, they may decide to adopt alternative products and services to satisfy some portion of their business needs.

If we fail to deliver timely releases of our products that are ready for use, release a new version, service, tool or update, or respond to new offerings by our competitors, or if new technologies emerge that are able to deliver competitive products more efficiently, more conveniently or more securely than our products, then our position in our markets could be harmed, and we could lose customers, which would adversely affect our business and results of operations.

Further, we must be able to keep pace with rapid regulatory changes in order to compete successfully in our markets. Our revenue growth depends on our ability to respond to frequently changing data protection regulations, policies and user demands and expectations, which will require us to incur additional costs to implement. The regulatory landscape in this industry is rapidly shifting, and we may become subject to new regulations that restrict our operations or materially and adversely affect our business, financial condition, and results of operations. For more information on our risks related to regulatory changes, see “—Risks Related to Regulation—We are subject to rapidly changing and increasingly stringent laws, contractual obligations and industry standards relating to privacy, data protection, data security and the protection of children. The restrictions and costs imposed by these requirements, or our actual or perceived failure to comply with them, could harm our business.”

Our ability to succeed within the markets that our solution suites address and continue to be profitable in the future depends upon a number of factors, including the cost, performance and perceived value associated with our individual products and solutions. Significant time, resources and expertise are required in order to build the technology that can deliver automated, high-quality user growth and monetization, while meeting user expectations for tailored experiences and relevant advertising. The trust and reputation we have built with our customers, who leverage our business platform to better scale and monetize their apps and further engage with their users, must constantly

28

be maintained with technological improvements, operational excellence and the ability to predict and adapt to the needs of our customers. If we fail to maintain that trust and reputation, our ability to grow our business may be materially and adversely impacted.

The markets for our solution suites could fail to grow significantly or there could be a reduction in demand for our products or solutions as a result of a lack of customer acceptance, technological challenges, competing products and services, decreases in spending by current and prospective customers, weakening economic conditions and other causes. If our markets do not continue to experience growth or if the demand for our products and solutions decreases, then we may not be as profitable as we have been in the past, and our business, financial condition and results of operations could be materially and adversely affected.

We rely on operating system providers and app stores to support our platform, and any disruption, deterioration or change in their services, policies, practices, guidelines and/or terms of service could have a material adverse effect on our reputation, business, financial condition and results of operations.

The success of our platform depends upon the effective operation of certain mobile operating systems, networks and standards that are run by operating system providers and app stores (which we collectively refer to as “Providers”). We do not control these Providers and as a result, we are subject to risks and uncertainties related to the actions taken, or not taken, by these Providers. We largely utilize Android-based and iOS-based technology, and in some cases, these Providers include companies that we also regard as our competitors.

The Providers that control these operating systems frequently introduce new technology, and from time to time, they may introduce new operating systems or modify existing ones. Further, we and our customers are also subject to the policies, practices, guidelines, certifications and terms of service of Providers’ platforms on which we and our customers create, run and monetize applications and content. These policies, guidelines and terms of service govern the promotion, distribution, content and operation generally of applications and content available through such Providers. Each Provider has broad discretion to change and interpret its terms of service, guidelines and policies, and those changes may have an adverse effect on us or our customers’ ability to use our platform. A Provider may also change its fee structure, add fees associated with access to and use of its platform or app store, alter how customers are able to advertise and monetize on their platform, change how the personal or other information of its users is made available to application developers on their platform, limit the use of personal information and other data for advertising purposes or restrict how users can share information on their platform or across other platforms. If we or our customers were to violate a Provider’s terms of service, guidelines, certifications or policies, or if a Provider believes that we or our customers have violated, its terms of service, guidelines, certifications or policies, then that Provider could limit or discontinue our or our customers’ access to its platform or app store. In some cases, these requirements may not be clear and our interpretation of the requirements may not align with the interpretation of the Provider, which could lead to inconsistent enforcement of these terms of service or policies against us or our customers and could also result in the Provider limiting or discontinuing access to its platform or app store. If our platform was unable to work effectively on these operating systems, either because of technological constraints or because the Provider impairs our ability to operate on their platform, this would have a material adverse effect on our business, financial condition and results of operations.

We also utilize operating systems from Providers to enable certain of our business operations, including our organization email services, and we expect that we will continue to rely on these systems going forward. Our reliance on operating systems reduces our control over quality of service and exposes us to potential service outages. If any problems occur with these operating systems, it may

29

cause errors or poor quality communications with our platform, and we could encounter difficulty identifying the source of the problems. The occurrence of errors or poor quality communications with our platform, whether caused by our platform or an operating system platform, may result in the loss of our existing customers or the delay of adoption of our products by potential customers and may materially and adversely affect our business, financial condition and results of operations.

Providers, such as Apple or Google, could also change their technical requirements, guidelines or policies in a manner that materially and adversely impacts the way in which we or our customers collect, use and share data from user devices, including restricting our ability to use or read device identifiers, other tracking features or other device data. Our ability to provide our customers with our user growth and monetization solutions relies on access to and collection of certain data, including resettable device identifiers and interactions with advertisements served by our monetization solutions for purposes such as serving advertisements, limiting the number of advertisements served to a specific device, detecting and preventing advertisement fraud, creating reports for customers, providing support to customers and measuring the effectiveness of advertisements. Without such data, we may not be able to serve such advertisements effectively, provide our products and solutions to customers, improve our products and solutions and remain competitive. There also is the risk that a Provider could limit or discontinue our access to its platform or app store if it establishes more favorable relationships with one or more of our competitors or it determines that it is in their business interests to do so, and we would have no recourse against any such Provider, which could have a material adverse effect on our business, financial condition and results of operations.

Further, at any time, these Providers can change their policies on how our customers or we operate on their platform or in their app stores by, for example, applying content moderation for apps and advertising or imposing technical or code requirements. Actions by Providers may affect the manner in which we or our customers collect, use and share data from user devices, which could have a material adverse effect on our and our customers’ businesses. In addition, if any of our customers have apps removed from app stores as a result of their use of our products, we may be forced to change our individual products, solution suites, practices or business, and we could be exposed to legal risk and lose customers.

For example, from April 26, 2021, Apple requires apps using its mobile operating system, iOS, to affirmatively (on an opt-in basis) obtain a user’s permission to “track them across apps or websites owned by other companies,” including for accessing their device’s advertising identifier. In June 2020, Apple announced that these changes would occur, and it was expected they would occur on or about this time. In anticipation of these changes, we invested resources, and may be required to invest additional resources, in order to implement certain changes in our data collection and use practices.

The effect of these changes will depend on various factors, including our ability to measure the effectiveness of ads, and the reaction by the industry to these changes, and may result in a material adverse effect on our business, financial condition and results of operations. We will have no recourse against Apple if these changes negatively impact our business, and we can provide no reassurance that other Providers, such as Google, which uses a similar advertising identifier, will not adopt similar measures in the future.

If any Providers, including either Android or iOS stop providing us with access to their platform or infrastructure, fail to provide reliable access, cease operations, modify or introduce new systems or otherwise terminate services, the delay caused by qualifying and switching to other operating systems could be time consuming and costly and could materially and adversely affect our business, financial condition and results of operations. Any limitation on or discontinuation of our or our customers’ access to any Provider’s platform or app store could materially and adversely affect our business, financial condition, results of operations or otherwise require us to change the way we conduct our business.

30

The markets in which we operate are competitive, and if we do not compete effectively, our business, financial condition and results of operations could be harmed.

The markets in which we operate are highly competitive. A significant number of companies have developed or are developing products and solutions that currently, or in the future may, compete with some or all of our individual products or solution suites. As we look to market and sell our solution suites and individual products to potential customers who use our existing products, we must convince their internal stakeholders that our solution suites are superior and/or more cost-effective to their current products and solutions.

We primarily compete with other technology platforms and digital content monetization services. Broadly, our competitors include well-established technology platforms that vary in size and compete with us primarily with their mobile monetization, growth and user acquisition solutions and services.

These competitors include Google Admob, Facebook Audience Network, Unity Software, MoPub by Twitter, AppLovin and Digital Turbine. We believe that our ability to compete effectively for customers depends upon many factors, including, but not limited to: providing a comprehensive set of solutions; increasing the volume depth of and ability to leverage data and analytics, while respecting privacy restrictions; the pace and quality of innovation; providing high-quality solution capabilities, including performance, scalability, security and reliability; effective advertising solutions; ability to drive business value for customers; strong brand reputation and recognition; ease of deployment, implementation and use of solutions; optimized price-performance benefits; and the quality of service and customer satisfaction. Our inability to compete favorably with respect to these factors could materially and adversely impact our business.

Our competitors vary in size and in the breadth and scope of the products or services offered. Some of our competitors and potential competitors have greater name recognition, longer operating histories, more established customer relationships, larger marketing budgets and greater financial and operational resources than we do. Further, other potential competitors not currently offering competing products or services may expand their offerings to compete with our products or solution suites or enter the markets through acquisitions, partnerships or strategic relationships. Certain competitors may choose to limit working with us, or cease working with us completely with respect to certain products or solution suites that we offer now or in the future, if such competitors provide competing products or solutions. In addition, our current and potential competitors may establish, or may have already established, cooperative relationships among themselves or with our customers or other third parties that may further enhance their resources and offerings in our addressable markets. Our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards and customer requirements. An existing competitor or new entrant could introduce new technology that is perceived to be easier to use or otherwise favorable to ours, which could reduce demand for our solution suites or individual products.

Further, some of our competitors may be acquired by other larger enterprises and or may make acquisitions, or enter into partnerships or other strategic relationships, that may provide more comprehensive offerings than they individually had offered, or may achieve greater economies of scale than us.

In addition to platform and technology competition, we face pricing competition. Some of our competitors offer competing products, which may be on more favorable terms, and has resulted in, and may continue to result in, pricing pressures. In addition, some of our competitors may offer more favorable payment terms to our customers compared to what we currently offer. We cannot assure you that we will not be forced to engage in price-cutting or revenue limiting initiatives, change payment terms or increase our advertising and other expenses to attract and retain customers in response to competitive pressures.

31

For all of these reasons, we may not be able to compete successfully against our current or future competitors, which could result in the failure of our solutions to continue to achieve or maintain customer and market acceptance, which would harm our business, financial condition and results of operations.

Our quarterly results of operations may fluctuate for a variety of reasons, and these fluctuations make it difficult for us to forecast our future results of operations and could result in our failure to meet our operating plan or the expectations of investors or analysts for any period.

Our results of operations have fluctuated in the past and are expected to fluctuate in the future due to a variety of factors, many of which are outside of our control. As a result, our past results may not be indicative of our future performance. In particular, our sales cycle can last several months for certain clients, and this sales cycle can be even longer, less predictable and more resource-intensive for larger enterprise customers. As a result, the timing of individual sales can be difficult to predict. In some cases, sales have occurred in a quarter subsequent to those we anticipated, or have not occurred at all, which can significantly impact our quarterly results and make it more difficult to meet market expectations.

In addition, our results of operations will continue to vary as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

32

Any of the above factors, individually or in the aggregate, may result in significant fluctuations in our financial and other operating results from period to period. These fluctuations make it difficult for us to forecast our future results of operations and could result in our failure to meet our operating plan or the expectations of investors or analysts for any period. As a result, you should not rely on our results or growth for any prior quarterly or annual periods as any indication of our future results or growth, and you should consider and evaluate our prospects in light of the risks and uncertainties frequently encountered by growing companies in rapidly-evolving markets. If we fail to meet such expectations for these or other reasons, the market price of our ordinary shares could fall substantially, and we could face costly lawsuits, including securities class action suits.

If we fail to maintain and enhance our brand, our ability to expand our customer base will be impaired, and our business, financial condition and results of operations may suffer.

We believe that maintaining and enhancing our brand reputation is important to expand sales of our products and solution suites to new and existing customers. We also believe that the importance of brand recognition will increase as competition in our markets increases. Successfully maintaining and enhancing our brand will depend largely on the effectiveness of our marketing efforts, our ability to offer reliable products that continue to meet the needs and preferences of our customers at competitive prices, our ability to maintain our customers’ trust, our ability to continue to develop new functionality to address a wide variety of customers’ needs and our ability to successfully differentiate our products from those of our competitors. Our brand promotion activities may not generate customer awareness or yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incur in building our brand.

Our brand and reputation could also be impacted by the types of content that developers publish using our platform. While we have processes in place to review the content that is published by developers, there can be no assurance that the content posted will follow the rules and not be deemed offensive or controversial, which could adversely affect our brand and reputation if the content was associated with us and our platform. We also rely on Providers, such as Google and Apple, to conduct reviews of the apps that are published on their respective app stores in accordance with the terms of use for their stores. If we or any such Provider fail to prevent any such offensive content, or if the content conflicts with our company values, our reputation may be negatively impacted.

Further, our brand may be impacted by things that are outside of our control, such as the actions taken by others in our industry or by independent third-parties, such as researchers, journalists, self-regulatory bodies and consumer groups, that could impact our industry as a whole. Researchers or consumer groups might undertake studies that cover our industry or our activity, as has occurred in the past, and such studies may result in negative publicity, or other actions taken by third parties that could damage our reputation or brand. Further, we conducted the Spin-Off (as defined below) of the assets of our Desktop business, and there can be no assurance that our brand would not suffer harm as a result of any claims that may arise in connection with the business that was spun off. If we fail to successfully promote and maintain our brand, our business, financial condition and results of operations may suffer.

33

Our business depends on our ability to retain and expand our existing customer relationships and attract new customers.

An important component of our future success is to retain and expand our relationships with existing customers and attract new customers. In order for us to maintain or improve our results of operations, it is important that we maintain positive relationships with our existing customers and that they are satisfied with the products and services we provide. We invest in targeted sales and account-based marketing efforts to identify opportunities to grow the use of our solution suites and products within and across our customer base, and we implement customer service strategies to identify opportunities to increase and sustain our customer base. We currently have a strong customer base within the mobile gaming markets, but are aiming to expand in both our current markets and new markets and there can be no assurance that our efforts will be successful. Further, there is ongoing customer consolidation and concentration within our markets, which could impair our ability to expand the customer base of our platform.

Our customer retention rates may decline or fluctuate as a result of a number of factors, some of which may be outside our control, such as the performance and perceived value associated with our platform, including their perception of our continued development of products that are important to them, the business strength or weakness of our customers, the success of our customers’ games and apps and their ability to monetize, the entry and success of competitive products and overall general economic conditions in the geographic regions in which we operate. However, our efforts may not be successful despite the resources we devote to them, and our customers may choose to switch to one of our competitors or choose to replace our products with similar technology that the customer creates internally.

Our telecom operator customers use our Aura solution suite to manage the device experience for their users, which helps them to manage both third-party and owned and operated services. To perform these services, we rely on the policies and procedures of telecom operators and OEMs and should those change, there could be an adverse impact on our products. For example, certain device OEMs have started to move towards issuing a single SKU, which may limit the functionality or create technical limitations on preloaded software or customizable features on such devices, based on criteria determined by the OEM. For instance, if an OEM determines that it will only support the installation of preloads following the completion of a device’s initial setup, we would only be able to provide the onboarding experience after the initial setup experience was completed and not as an integral part of the setup experience, resulting in less installs, which would affect our revenues. There can be no assurance that if more device OEMs choose to issue single SKUs in their devices, that we will be able to maintain the functionality that we provide to our Aura customers, which could adversely affect our business, financial condition and results of operations.

Similarly, our sales efforts could be adversely impacted if customers and their users perceive that features incorporated into competitive platforms or their own technologies reduce the relevance or attractiveness of our solution suites. Gaming companies may choose to invest significant efforts in their own internally-generated technologies and replace certain of our products with their own technologies unless they perceive our solution suites as offering significant incremental long-term benefits. Any decrease in user satisfaction with our platform or customer support would also harm our brand and word-of-mouth referrals, which, in turn, would hamper our ability to attract new customers. It is also an important part of our strategy to expand our customers’ use of our platform by cross-selling our products and solution suites. While we believe there are significant cross-selling opportunities between our solution suites and products, we cannot be sure that our efforts will be successful.

Our customers range from large global enterprises to mid-sized, small and independent businesses and individuals, and as such, our agreements with each customer type vary in length and

34

terms. Many of our agreements allow customers to terminate the agreement at their convenience and do not provide for minimum usage or guaranteed scale. There can be no assurance that we will be able to successfully negotiate new agreements with these customers when the existing agreements end.

If we do not retain our existing customers, attract new customers or if our customers do not expand their use of our platform and purchase additional solutions from us, our revenue may not increase or may decline and our business, financial condition and results of operations may be harmed.

We rely on our customers that contribute more than $100,000 of annual revenue, and sales to these customers require a stronger sales team as compared to other customers.

One of the factors affecting our growth and financial performance is the continued use of our solution suites by customers contributing more than $100,000 of annual revenue. As of June 30, 2021, these 309 customers represented 94% of our total revenue. While we believe that our relationships with these customers are strong, there can be no assurance that we will be able to maintain or expand these existing relationships, which could have a material adverse effect on our business, financial condition and results of operations.

In order to increase the adoption of our products and solution suites by customers that we believe can contribute more than $100,000 of revenue over a 12-month period and to expand into new industries where potential customers are typically large organizations, we rely on our direct sales team. Although our direct sales team is working to expand into industries beyond gaming we have relatively limited experience selling our solutions in industries outside gaming apps, and there can be no assurance that our direct sales team will be effective in attracting customers in industries beyond gaming in line with our growth strategies.

In addition, sales to large customers involve risks that may not be present or that are present to a lesser extent with sales to smaller customers, such as longer sales cycles that average between four and six months but can extend up to twelve months for certain of our customers, more complex customer requirements, substantial upfront sales costs and less predictability in completing some of our sales. For example, large customers may require considerable time to evaluate and test our solutions and those of our competitors prior to making a decision or may have specific compliance and product requirements that we may not meet. A number of factors influence the length and variability of our sales cycle, including the competitive nature of evaluation and approval processes, extensive tests and review of our technology capabilities, examination of our data security measurements and adherence with security requirements. As a result, the length of our sales cycle, from identification of the opportunity to deal closure, may vary significantly from customer to customer, with sales to large customers typically taking longer to complete. Moreover, larger customers often begin to deploy our solution suites on a limited basis, but nevertheless may demand development and integration services, which increase our upfront investment in the sales effort with no guarantee that these customers will deploy our solutions widely enough across their organization to justify our substantial upfront investment. If we fail to increase adoption of our solutions by larger customers, our growth could be impaired.

If we do not successfully and efficiently manage our current and potential future growth, our business, financial condition and results of operations could be harmed.

In recent years, we have significantly grown the scale of our business, and the growth and expansion of our business places significant strain on our management and our operational and financial resources. As usage of our platform grows, we will need to devote additional resources to

35

improving its capabilities, features and functionality, and scaling our business, IT, financial, operating and administrative systems. There can be no assurance that we will appropriately allocate our resources in a manner that results in increased revenue or other growth in our business. Any failure of or delay in these efforts could result in impaired performance and reduced customer satisfaction, resulting in decreased sales to new customers or lower dollar-based net expansion rates (as defined in “ironSource’s Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Metrics and Non-GAAP Financial Metrics”), which would hurt our revenue growth and our reputation. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknown factors that may result in losses in future periods. Even if we are successful in our expansion efforts, they will be expensive and complex and require the dedication of significant management time and attention. We may also suffer inefficiencies or service disruptions as a result of our efforts to scale our internal infrastructure. We cannot be sure that the expansion of and improvements to our internal infrastructure will be effectively implemented on a timely basis, if at all, and such failures could harm our business, financial condition and results of operations.

Our business growth is dependent upon the continued growth of the App Economy and the increased usage of smartphones, tablets and other connected devices.

Our business growth depends on the continued proliferation of mobile connected devices, such as smartphones and tablets, which can connect to the Internet over a cellular, wireless or other network, as well as the increased consumption of content through those devices. Consumer usage of these mobile connected devices may be inhibited for a number of reasons, such as:

In particular, the increased usage of smartphones, tablets and other mobile connected devices is dependent upon user sentiment and the increased availability of such devices. Public opinion towards mobile connected devices and other similar technological advancements is rapidly evolving, and as such, our industries have faced criticism in the past. We cannot be certain that the public will continue to support new technologies, such as app-based gaming and advertising. If we lose public interest and support for mobile gaming and apps, it could have a material adverse effect on our business, financial condition and results of operation.

We saw a moderate increase in demand for certain of our products and solution suites following the implementation of shelter-in-place orders, as we believe these restrictions provided individuals more time to spend online and higher levels of user engagement within the mobile ecosystem. Although we are seeing an increase in time that users spend playing games, which results in more engagement with ads and has led to an increase in the use of our platform, there can be no assurance that this increase will continue once global shelter-in-place restrictions are lifted and the COVID-19 pandemic has subsided. Furthermore, while our financial condition and results of operations were not negatively impacted by the COVID-19 pandemic, its impact on our future growth and our results of operations is unknown, and we are unable to accurately predict any future impacts. There can be no assurance that the increases we have seen this year will continue over time whether during or after the COVID-19 pandemic.

36

In addition, the Internet infrastructure that we and our customers rely on in any particular geographic area may be unable to support the demands placed upon it, which could interfere with the speed and availability of our platform. As a result, we could lose customers if the infrastructure is unable to support our platform or solution suites, which could have a material adverse effect on our business, financial condition and results of operations.

For any of these reasons, users of mobile connected devices may limit the amount of time they spend on these devices and the number of applications or amount of content they download on these devices. If user adoption of mobile connected devices and user consumption of content on those devices do not continue to grow, our total addressable market size may be significantly limited, which could compromise our ability to increase our revenue and our ability to become profitable.

If we are unable to further expand into the wider App Economy or if our solutions for industries beyond gaming fail to achieve market acceptance, our growth and operating results could be adversely affected, and we may be required to reconsider our growth strategy.

Our growth strategy is based, in part, on expanding into industries that go beyond mobile gaming apps into the broader App Economy. These industries are still in the early stages of development, and it is uncertain whether these types of apps will provide the opportunities for expansion that we currently expect, as well as how rapidly these opportunities may materialize, if at all.

Our success in expanding into these industries will depend, to a substantial extent, on our ability to scale our business to tailor our existing solution suites and products to these different types of apps, provide new and improve existing products to our new and existing customers and enable these customers to further monetize their apps across the ecosystem. Market acceptance of our solution suites and products for new customers outside of mobile gaming may not grow as we expect as a result of a number of factors, including the cost, performance and perceived value associated with our products and our ability to adapt to the differing sales and marketing requirements appropriate to most effectively address these industries. In addition, our ability to achieve widespread adoption of our products by new customers in industries beyond gaming may be affected by the entry and success of competitive products, including from larger competitors with greater resources that have historically addressed these industries with legacy products, and accordingly, have more brand recognition in these industries. If our products do not achieve widespread adoption in these other markets, our ability to grow our revenue may suffer.

We are dependent on the success of the gaming and mobile app ecosystem. Adverse events relating to this ecosystem, including events related to our customers or their apps, could have a negative impact on our business.

We are dependent on the success of the gaming and mobile app ecosystems to sustain and increase our business, including the success of our customers and their apps. Our customers are game and app developers, advertising networks, telecom operators, OEMs and others who use our solution suites to control their advertisements, publish their apps and games and monetize and generate growth of use of their apps and increase engagement with their users. As a result, our success depends in part on the gaming and mobile app ecosystem, which includes our current and potential new customers creating new apps and then using our products to market, sell and scale their apps, and then continue to use our products to further grow and monetize their apps as their apps continue to gain popularity. If a significant amount of our customers’ marketing and advertising efforts are unsuccessful or if a large amount of our customers experience a decrease in demand for their apps, our revenue could be reduced. The gaming and mobile app ecosystem is characterized by intense competition, rapid technological change and economic uncertainty and, as such, there is no guarantee that any of our customers’ apps will gain any meaningful traction with users. In addition,

37

some of our solution suites are more reliant on certain customers and their ability to continue to use our solutions to engage with their users. While our large and diverse customer portfolio has helped to reduce the fluctuations in our revenue as a whole, we cannot assure you that the size and diversification of our customer portfolio will sufficiently mitigate this risk. If our customers fail to market and monetize their apps or devices using our solutions, and we are not able to maintain a diversified portfolio of customers, our business, financial condition and results of operations may be materially and adversely affected.

Our business is subject to risks generally associated with the mobile gaming industry.

81.6% of our 2020 revenue was derived from customers in the mobile gaming industry, and we rely to a significant extent on the health of the mobile gaming industry and the success of our customers’ games to maintain and increase our revenue. Accordingly, we are especially susceptible to market conditions and risks associated with the mobile gaming industry, including the popularity, price and timing of release of games, changes in consumer demographics, the availability and popularity of other forms of entertainment and public tastes and preferences, all of which are difficult to predict and are beyond our control. In order to be successful, our customers must also develop effective marketing strategies for games; expand and enhance games after their initial release; attract experienced game designers, product managers and engineers; and adapt to an increasingly diverse set of mobile devices, including various operating systems and specifications, limited bandwidth, and varying processing power and screen sizes.

In addition, users may view games as a discretionary purchase. Although in periods of economic downturn time spent on gaming typically increases, if we experience a prolonged downturn as a result of the effects of COVID-19 or otherwise, users may reduce their discretionary spending on games, and our customers, in turn, may see an adverse effect on their business and reduce their usage of or lower their spending on our solution suites, which would adversely impact our revenue and financial condition. Economic conditions that negatively impact discretionary consumer spending, including inflation, slower growth, unemployment levels, tax rates, interest rates, energy prices, declining consumer confidence, recession and other macroeconomic conditions, including those resulting from COVID-19 and from geopolitical issues and uncertainty, could have a material adverse impact on our business, financial condition and results of operations.

If we or our competitors fail to detect or prevent fraud on our respective platforms, or malware intrusion into the systems or devices of customers and their users, customers could lose confidence in our or our competitors’ platforms, and we could face legal claims that could materially and adversely affect our reputation, business, financial condition and results of operations.

We and our competitors may be subject to fraudulent or malicious activities undertaken by persons or third parties seeking to use our or our competitors’ platforms for improper purposes. For example, someone may attempt to divert or artificially inflate mobile apps users’ actions recorded in our platform or to disrupt or manipulate the operation of the systems and devices of our customers and their users in order to misappropriate information, generate fraudulent billings or stage cyberattacks or for other illicit purposes. Bad actors may also introduce malware through our or our competitors’ platforms in order to commandeer or gain access to information of our customers or partners. For example, sophisticated bot-nets and other complex forms of “click fraud” might be used to generate fraudulent impressions and divert advertising revenue from the legitimate apps of our customers.

We may also be subject to fraud and other types of malicious activity by competitors for the purpose of manipulating the allocation of advertising budgets across our, or our competitors’ platforms. If we fail to detect such activity, this could divert advertising revenue from us to our competitors. We

38

use third-party tools and proprietary technology to identify non-human traffic and malware, and we may reduce or terminate relationships with customers or partners that we find to be engaging in any such activities, which could adversely affect our revenue and harm our relationships with our other customers or partners. Although we continuously assess the quality and performance of advertising on customers’ digital media properties, it may be difficult to detect fraudulent or malicious activity, and we rely on our own and third-party tools, as well as the controls of our customers. Further, perpetrators of fraudulent impressions and malware frequently change their tactics and may become more sophisticated over time, requiring both us and our competitors or others in our industry to improve processes for assessing the quality of customers’ inventory and controlling fraudulent activity. If we or our competitors fail to detect or prevent fraudulent or malicious activity of this sort, our reputation, or the broader reputation of our industry, could be damaged, and our customers may contest payment, demand refunds or fail to give us future business, or we could face legal claims from our customers. Even if we are not directly involved in fraud or malicious activity, any sustained failures of others in our industry to adequately detect and prevent fraud could materially and adversely affect the industry and its reputation, which would have a material adverse effect on our business, financial condition and results of operations.

If we or our third-party service providers experience a security breach or unauthorized parties otherwise obtain access to our customers’ data, our data or our platform, then our platform may be perceived as not secure, and our reputation may be harmed, our business operations may be disrupted, demand for our solution suites may be reduced and we may incur significant liabilities.

Operating our business platform involves the collection, storage and transmission of proprietary and confidential information, including personal information of our employees, customers and users of our customers’ products, our proprietary and confidential information and the confidential information we receive from our partners, customers and users. Our internal computer systems and those of our current and any future strategic collaborators, vendors and other contractors or consultants are vulnerable to damage from cyber-attacks, computer viruses, unauthorized access, natural disasters, cybersecurity threats, terrorism, war, telecommunication, and electrical failures. The security measures we take to protect this information may be breached as a result of cyber-attacks, computer malware, viruses, unauthorized access, natural disasters, cybersecurity threats, terrorism, war, telecommunication, electrical failures, social engineering (including, but not limited to, spear phishing and ransomware attacks), hacking and other efforts by individuals or groups of hackers and sophisticated organizations, including state-sponsored organizations or nation-states, organized crime, other criminal enterprises, individual actors and/or advanced persistent threat groups. In addition, we may experience intrusions on our physical premises by any of these threat actors.

Cyber incidents have become more prevalent in recent years and been increasing in sophistication and frequency. Incidents may include third parties attempting to gain access to employee or customer data using stolen or inferred credentials, computer malware, viruses, spamming, phishing attacks, ransomware, card skimming code and other deliberate attacks and attempts to gain unauthorized access. Because the techniques used by computer programmers who may attempt to penetrate and sabotage our network security or our website change frequently and may not be recognized until launched against a target, we may be unable to anticipate these techniques.

For example, attempts by malicious actors to frequently induce our personnel into disclosing usernames, passwords or other information that can be used to access our systems have increased and could be successful. Our security measures could also be compromised by personnel, theft or errors or be insufficient to prevent harm resulting from security vulnerabilities in software or systems on which we rely. Such incidents may occur in the future, resulting in unauthorized, unlawful or inappropriate access to, inability to access, disclosure of or loss of the sensitive, proprietary and

39

confidential information that we handle. Security incidents could also damage our IT systems and our ability to make the financial reports and other public disclosures required of public companies.

We rely on third-party service providers to provide critical services that help us maintain, develop and deliver our solutions and operate our business. In the course of providing their services, these providers may support or operate critical business systems for us or store or process personal information and any of the same proprietary and confidential information that we handle. These service providers may not have adequate security measures and could experience a security incident that compromises the confidentiality, integrity or availability of the systems they operate for us or the information they process on our behalf. Such occurrences could materially and adversely affect our business to the same degree as if we had experienced these occurrences directly, and we may not have recourse, or have limited recourse, from the responsible third-party service providers for the resulting liability we incur.

Because there are many different cybercrime and hacking techniques and such techniques continue to evolve, we may be unable to anticipate attempted security breaches, react in a timely manner or implement adequate preventative measures. While we have developed and implemented systems and processes designed to protect the integrity, confidentiality and security of our customers’ and their users’ confidential and personal information under our control, we cannot guarantee that any security measures that we or our third-party service providers have implemented will be effective against current or future security threats. A security breach or other security incident, or the perception that one has occurred, could result in a loss of customer confidence in the security of our platform and damage to our reputation and brand, loss or unavailability of data which we may not be able to effectively restore, reduce demand for our products, disrupt normal business operations, require us to incur material costs to investigate and remedy the incident, recover data if possible, and prevent recurrence, expose us to litigation, regulatory enforcement action, fines, penalties and damages and materially and adversely affect our business, financial condition and results of operations. These risks are likely to increase as we continue to grow and process, store and transmit an increasingly large volume of data.

We have contractual and legal obligations to notify relevant stakeholders of security breaches. Most jurisdictions have enacted laws requiring companies to notify individuals, regulatory authorities and others of security breaches involving certain types of data. In addition, our agreements with certain customers and third-party partners may require us to notify them in the event of a security breach. Such mandatory disclosures are costly, could lead to negative publicity and may cause our customers to lose confidence in the effectiveness of our security measures.

A security breach could lead to claims by our customers, their users or other relevant parties that we have failed to comply with contractual obligations to implement specified security measures. As a result, we could be subject to legal action or our customers could end their relationships with us. We cannot assure you that the limitations of liability in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages. Pursuant to the California Consumer Privacy Act (the “CCPA”) (and the forthcoming California Privacy Rights Act (the “CPRA”)), if we experience a security breach, California consumers could bring a private right of action claiming the breach was the result of our violation of the duty to implement and maintain reasonable security procedures and practices, which could be costly and cause reputational harm. Similarly, there is an increasing risk of class actions in the United Kingdom and Europe. Security breaches could also result in enforcement actions by government or regulatory authorities alleging that we have violated laws that require us to maintain reasonable security measures and comply with mandatory disclosure requirements.

While we do have coverage for cybersecurity attacks, we cannot be certain that our insurance coverage will be adequate for data security liabilities actually incurred, will cover any indemnification

40

claims against us relating to any incident, will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could adversely affect our reputation, business, financial condition and results of operations.

In addition, we continue to expend significant costs to seek to protect our platform and to introduce additional security features for our customers, and we expect to continue to have to expend significant costs in the future. For example, some of our products are SOC 2 compliant, in order to meet the standards that our telecom operator customers require to prevent a security breach, and we may be requested by clients in the future to obtain SOC 2 compliance for additional products. Any increase in these costs will adversely affect our business, financial condition and results of operations.

Interruptions, performance problems or defects associated with our platform could diminish our brand, subject us to liability and may materially and adversely affect our business, financial condition and results of operations.

Our reputation and ability to attract and retain customers and grow our business depends in part on our ability to operate our platform at high levels of reliability, scalability and performance, including the ability of our existing and potential customers to access our platform at any time and within an acceptable amount of time. Interruptions in the performance of our solution suites or any of our individual products, whether due to system failures, computer viruses or physical or electronic break-ins, could affect the availability of our solution suites, our data or any of our individual products. We may experience disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, introductions of new functionality, human or software errors, capacity constraints due to an overwhelming number of customers accessing our platform simultaneously, denial of service attacks or other security-related incidents.

It may become increasingly difficult to maintain and improve our performance, especially during peak usage times and as our customer base grows and our platform becomes more complex. If our platform is unavailable or if our customers are unable to access our products within a reasonable amount of time or at all, we may experience a loss of customers, lost or delayed market acceptance of our solution suites, delays in payment to us by customers, injury to our reputation and brand, legal claims against us, significant costs of remedying these problems, significant costs of compensating customers to maintain our relationships and the diversion of our resources. In particular, certain of our customers, such as our telecom operator customers, rely on our platform to provide services to their users, and if there was any interruption, disruption, security breach or similar event, this could have a negative effect on our telecom operator customers’ reputations with their users, which would materially harm our relationships with these customers and could lead to us losing some, or all, of these customers, which would have a material adverse effect on our business, financial condition and results of operations. In addition, to the extent that we do not effectively address capacity constraints, upgrade our systems as needed and continually develop our technology and network architecture to accommodate actual and anticipated changes in technology, our business, financial condition and results of operations, as well as our reputation, may be materially and adversely affected.

Further, the technology underlying our platform is inherently complex and may contain material defects or errors, particularly when new products are first introduced or when new features or capabilities are released. We have from time to time found defects or errors in our platform, and new defects or errors in our existing products or new products may be detected in the future by us or our users. We cannot assure you that our existing products and new products will not contain defects. Any such defects could result in loss of revenue and loss of customer confidence in our platform, even if

41

only one of our products contained defects. Any real or perceived errors, failures, vulnerabilities or bugs in our solution suites or individual products could result in negative publicity or lead to data security, access, retention or other performance issues, all of which could harm our business. The costs incurred in correcting such defects or errors may be substantial and could harm our business. Moreover, the harm to our reputation and legal liability related to such defects or errors may be substantial and could similarly harm our business. If any of the foregoing occurred, it could have a material adverse effect on our business, financial condition and results of operations.

We rely on the performance of, and we face stark competition for, highly skilled personnel, including our management, other key employees and qualified employees, and the loss of one or more of such personnel or of a significant number of our team members or the inability to attract and retain executives and qualified employees we need to support our operations and growth, could harm our business.

Our success and future growth depend upon the continued services of our management team and other key employees. In particular, the founders who are members of our leadership team are critical to our overall management, as well as the continued development of our solutions, our culture and our strategic direction. From time to time, there may be changes in our management team resulting from the hiring or departure of executives and key employees, which could disrupt our business. We also are dependent on the continued service of our existing engineering team because of the complexity of our platform. We may terminate any employee’s employment at any time, with or without cause, and any employee may resign at any time, with or without cause, subject only to the notice periods prescribed by their respective agreements if done without cause. The loss of one or more members of our senior management or key employees could harm our business, and we may not be able to find adequate replacements. We cannot ensure that we will be able to retain the services of any members of our senior management or key employees.

In addition, to execute our growth plan, we must attract and retain highly qualified personnel. We have had difficulty quickly filling certain open positions in the past, and we expect to have significant future hiring needs. Competition is intense, particularly in Israel and other areas in which we have offices, for data scientists, engineers experienced in designing and developing cloud-based platform products, research and development specialists and experienced sales professionals. In order to continue to access top talent, we will likely continue to grow our footprint of office locations, which may add to the complexity and costs of our business operations. From time to time, we have experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or we have breached their legal obligations, resulting in a diversion of our time and resources. In addition, prospective and existing employees often consider the value of the equity awards they receive in connection with their employment. If the perceived value of our equity awards declines, experiences significant volatility or increases such that prospective employees believe there is limited upside to the value of our equity awards, it may adversely affect our ability to recruit and retain key employees. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects would be harmed.

We generally enter into non-competition agreements with our employees. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. We may be unable to enforce these agreements under the laws of the jurisdictions in which our employees work, and it may be difficult for us to restrict our competitors from benefiting from the expertise our former employees developed while working for us. For example, Israeli labor courts have required employers seeking to enforce non-compete undertakings of a former

42

employee to demonstrate that the competitive activities of the former employee will harm one of a limited number of material interests of the employer that have been recognized by the courts, such as the protection of a company’s trade secrets or other intellectual property.

Our corporate culture has contributed to our success and, if we are unable to maintain it as we grow, our business, financial condition and results of operations could be harmed.

We have experienced and may continue to experience rapid expansion in the number of our employees. We believe our corporate culture has been a key element of our success. However, as our organization grows, it may be difficult to maintain our culture, which could reduce our ability to innovate and operate effectively. The failure to maintain the key aspects of our culture as our organization grows could result in decreased employee satisfaction, increased difficulty in attracting top talent, increased turnover and could compromise the quality of our customer service, all of which are important to our success and to the effective execution of our business strategy. In the event we are unable to maintain our corporate culture as we grow to scale, our business, financial condition and results of operations could be materially and adversely affected.

We rely upon third-party data centers and providers of cloud-based infrastructure to host our platform. Any disruption in the operations of these third-party providers, limitations on capacity or interference with our use could materially and adversely affect our business, financial condition and results of operations.

We currently serve our customers from data centers in the United States and Ireland and other locations worldwide, which are operated by a third-party cloud hosting provider. We use various third-party cloud hosting providers, such as Amazon Web Services (“AWS”), to provide cloud infrastructure for our platform. Our platform relies on the operations of this infrastructure. Customers need to be able to access, send requests and receive communication from our platform at any time, without interruption or degradation of performance, and we provide some customers with service-level commitments with respect to uptime. In addition, our platform depends on the ability of these data centers and cloud infrastructure to allow for our customers’ configuration, architecture, features and interconnection specifications and to secure the information stored in these data centers. Any limitation on the capacity of our data centers or cloud infrastructure could impede our ability to onboard new customers or expand the usage of our existing customers, host our platform or serve our customers, which could materially and adversely affect our business, financial condition and results of operations. In addition, any incident affecting our data centers or cloud infrastructure that may be caused by cyber-attacks, natural disasters, fire, flood, severe storm, earthquake, power loss, outbreaks of contagious diseases, telecommunications failures, terrorist or other attacks and other similar events beyond our control could negatively affect the cloud-based portion of our platform. A prolonged service disruption affecting our data centers or cloud-based services for any of the foregoing reasons would negatively impact our ability to serve our customers and could damage our reputation with current and potential customers, expose us to liability, cause us to lose customers or incur additional costs under our customer and partner agreements or otherwise harm our business. We may also incur significant costs for using alternative providers or taking other actions in preparation for, or in response to, events that damage the third-party hosting services we use.

In the event that our service agreements relating to our data centers or cloud infrastructure are terminated or there is a lapse of service, elimination of services or features that we utilize, interruption of internet service provider connectivity or damage to such facilities, we could experience interruptions in access to our platform, loss of revenue from revenue-share and usage-based solutions, as well as significant delays and additional expense in arranging or creating new facilities and services or re-architecting our platform for deployment on a different data center provider or cloud infrastructure service provider, which could materially and adversely affect our business, financial condition and results of operations.

43

Health epidemics, including the current COVID-19 pandemic, could in the future have an adverse impact on our business, operations and the markets and communities in which we, our partners and customers operate.

Our business and operations could be materially and adversely affected by health epidemics, including the current COVID-19 pandemic, impacting the markets and communities in which we and our customers operate. The COVID-19 pandemic has caused, and continues to cause, significant business and financial markets disruption worldwide, and there is significant uncertainty around the duration of this disruption on a global level, as well as the ongoing effects on our business.

We saw a moderate increase in demand for certain of our products and solution suites following the implementation of shelter-in-place orders. There can be no assurance that this increase will continue over time whether during or after the COVID-19 pandemic. While our financial condition and results of operations were not negatively impacted by the COVID-19 pandemic, the full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted, and we may be unable to accurately forecast our revenue or financial results.

Further, as certain of our customers experience downturns or uncertainty in their own business operations or revenue resulting from the spread of COVID-19, they may decrease or delay their spending, request pricing concessions or seek renegotiations of their contracts and decrease their use of our products, any of which could have a material adverse effect on us. The COVID-19 pandemic has resulted in a dramatic increase in unemployment that could lead to users having less discretionary income to spend on games, which could have a negative impact on the mobile app industry. In addition, we may experience customer losses, including due to bankruptcy or our customers ceasing operations, which may result in an inability to collect receivables from these parties. A decline in revenue or the collectability of our receivables could harm our business.

In addition, as the Israeli and other governments around the world imposed shelter-in-place and other restrictive measures, we transitioned many of our employees to remote working arrangements and temporarily closed our offices in Israel, the United States, China and other jurisdictions as required by applicable local authorities from time to time. We have gradually reopened certain of our offices in accordance with the lifting of certain shelter-in-place measures and in accordance with measures that provide additional safeguards that we believe are in the best interests of our employees and customers. While our employees have been gradually allowed to return to our offices in accordance with the applicable local laws, we also have provided the flexibility to our employees to continue to work remotely as the COVID-19 pandemic wears on. We implemented further safeguards in the interest of the health and safety of our employees and customers, and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers and partners. Although our employees have continued to perform well despite working remotely, there is no guarantee that we will continue to be as effective while working remotely because our team is dispersed, employees may have less capacity to work due to increased personal obligations (such as childcare, eldercare or caring for family members who become sick), may become sick themselves and be unable to work or may be otherwise negatively affected, mentally or physically, by the COVID-19 pandemic and prolonged social distancing. Decreased effectiveness and availability of our team could adversely affect our results due to slowdowns in our sales cycles and recruiting efforts, delays in our entry into customer contracts, delays in addressing performance issues, delays in product development, delays and inefficiencies among various operational aspects of our business, including our financial organization, or other decreases in productivity that could seriously harm our business.

Furthermore, we may decide to postpone or cancel planned investments in our business in response to changes in our business as a result of the spread of COVID-19, which may impact our

44

ability to attract and retain customers and our rate of innovation, either of which could harm our business. In addition, our facilities’ needs could evolve based on continuing changes and impact on work environments as a result of the COVID-19 pandemic, and we may not be able to alter our contractual commitments to accommodate such changes, which could cause us to incur additional costs or otherwise harm our business. More generally, the COVID-19 pandemic has materially and adversely affected economies and financial markets globally, which could decrease technology spending and materially and adversely affect demand for our platform.

The global impact of the COVID-19 pandemic continues to rapidly evolve, and we will continue to monitor the situation and the effects on our business and operations closely. We do not yet know the full extent of potential impacts on our business, operations or the global economy as a whole, particularly if the COVID-19 pandemic and related public health measures persist for an extended period of time. Given the uncertainty, we cannot reasonably estimate the impact on our future results of operations, cash flows or financial condition. While the spread of COVID-19 may eventually be contained or mitigated, there is no guarantee that a future outbreak of this or any other widespread epidemics will not occur, or that the global economy will recover, either of which could harm our business.

If our customers do not obtain necessary and requisite consents from users for us to process their personal data, we could be subject to fines and liability.

Because we do not have direct relationships with users of some of our products, we rely on our customers to obtain the consent of the user on our behalf to process their data, and to implement any notice or choice mechanisms required under applicable laws, but if our customers do not follow this process (and in any event, as the legal requirements in this area continue to evolve and develop), we could be subject to fines and liability. We may not have adequate insurance or contractual indemnity arrangements to protect us against any such claims and losses.

The estimates of our market opportunity and forecasts of market growth included in this prospectus may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business could fail to grow at a similar rate, if at all.

The estimates of our market opportunity and forecasts of market growth included in this prospectus may prove to be inaccurate. Market opportunity estimates and growth forecasts included in this prospectus, including those we have generated ourselves, are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The variables that affect the calculation of our market opportunity are also subject to change over time.

Our expectations regarding potential future market opportunities are subject to even greater uncertainty. For example, our expectations regarding future market opportunities depend, among other things, on the extent to which we are able to develop new products and features that expand the applicability of our individual products and/or our solution suites. In addition, our expectations regarding future market opportunities are subject to uncertainties. Our ability to address those opportunities will depend on our developing solutions that are responsive to those particular industries’ and customers’ needs.

In addition, any expansion in our markets depends on a number of factors, including the cost, performance and perceived value associated with our products and those of our competitors. Even if the markets in which we compete meet the size estimates and growth forecasted in this prospectus, our business could fail to achieve a substantial share of these markets or grow at a similar rate, if at all. Our growth is subject to many risks and uncertainties. Accordingly, the estimates of market opportunity or forecasts of market growth included in this prospectus should not be taken as indicative of our future growth.

The recent Spin-Off of the assets of our Desktop business from ironSource Ltd. may give rise to potential liabilities for us in the event of a breach of our or our shareholders’ obligations under the agreements related to the Spin-Off or tax liabilities caused by the Spin-Off.

On December 31, 2020, we completed the spin-off of the assets of our Desktop business to TypeA Holdings Ltd., a newly formed company incorporated under the laws of Israel, (the “Spin-Off”) which is owned by our shareholders on a pro rata basis as of the date of the Spin-Off. The Spin-Off was effected through an asset transfer agreement in which each party undertook certain obligations with respect to tax caused by the Spin-Off and other liabilities of the other party. In connection with the Spin-Off, we obtained a ruling from the Israeli Tax Authority in accordance with Section 104B(f) of the Israeli Income Tax Ordinance (New Version), 5721 – 1961 (the “Ordinance”), in which the Israeli Tax Authority agreed that the transfer of the assets of our Desktop business to TypeA is not taxable to us as of the date of transfer (collectively, the “Spin-Off Ruling”). The Spin-Off Ruling is subject to our and our shareholders’ compliance with Section 104B(f) of the Ordinance, which includes a requirement that shareholders of ironSource Ltd. as of the date of the Spin-Off continue to hold at least 25% of the share capital of each of ironSource Ltd. and TypeA until December 31, 2022 (the “25% Requirement”). The 25% Requirement may be breached if, either as a result of transfers of shares by our shareholders of record as of the Spin-Off, or as a result of issuances of new shares by ironSource Ltd. or TypeA, our shareholders of record as of the spin-off hold less than 25% of our or TypeA’s share capital. Certain of our shareholders holding together approximately 81.7% of our ordinary shares pre-Business Combination (based on our outstanding share capital immediately prior to the Business Combination) entered into a lock-up agreement restricting each such shareholder from transferring more than 50% of its shares in ironSource Ltd. or TypeA immediately after the Spin-Off until December 31, 2022 (the “Spin-Off Lockup”).

Under the terms of the Spin-Off Lockup, our shareholders that entered into the Spin-Off Lockup are permitted to transfer shares that exceed the 50% restriction contained in the Spin-Off Lockup in ironSource Ltd. or TypeA if they receive written consent from Tomer Bar-Zeev, in his capacity as a shareholder, and App Investments S.á.r.l. (the “CVC Vehicle”). Since we are not a party to the Spin-Off Lockup, we would not be able to prevent our shareholders from violating the terms of the 25% Requirement if they received consent to transfer their shares in excess of the 50% restriction. Should any shareholder obtain consent to transfer shares that exceed the 50% restriction, this could violate the terms of the 25% Requirement and subject us and our shareholders of record as of the date of the Spin-Off to a significant tax liability.

We cannot be certain that the applicable shareholders will comply with the Spin-Off Lockup or that the 25% Requirement will be otherwise complied with. In the event that either we or our shareholders of record as of the Spin-Off fail to comply with the Spin-Off Ruling, including the 25% Requirement, we may be subject to a significant tax liability arising from the Spin-Off, which would adversely affect our results of operations. Similarly, despite the Spin-Off, we may still be liable for events and circumstances occurring prior to the Spin-Off, which may have an adverse impact on our business, financial condition and results of operations.

Indemnity provisions in various agreements to which we are a party potentially expose us to substantial liability for infringement, misappropriation or other violation of intellectual property rights, data protection and other losses.

Our agreements with our customers and other third parties may include indemnification provisions under which we agree to indemnify or otherwise be liable to them for losses suffered or incurred as a result of claims of infringement, misappropriation or other violation of intellectual property rights, data protection or other data rights, damages caused by us to property or persons, or other liabilities relating to or arising from our software, technology, platform, our acts or omissions under

46

such agreements or other contractual obligations. Some of our agreements, and renewals of such agreements, provide for uncapped liability or incorporate carve outs for certain obligations and some indemnity provisions survive termination or expiration of the applicable agreement. Large indemnity payments would harm our business, financial condition and results of operations. Although we attempt to contractually limit our liability with respect to such indemnity obligations, in some cases, the liability is not limited given other strategic facets of the relationship and we may still incur substantial liability related to such agreements, and we may be required to cease providing certain functions or features on our platform as a result of any such claims. Even if we succeed in contractually limiting our liability, such limitations may not always be enforceable. Any dispute with a customer or other third party with respect to such obligations could have adverse effects on our relationship with such customer or other third party and other existing or prospective customers, reduce demand for our platform and materially and adversely affect our business, financial condition and results of operations. In addition, although we carry general liability insurance, our insurance may not be adequate to indemnify us for all liability that may be imposed on us or otherwise protect us from liabilities or damages with respect to claims, including clams on such matters as alleged compromises of customer data, which may be substantial. Any such coverage may not continue to be available to us on acceptable terms or at all.

Acquisitions, strategic investments, partnerships and alliances could be difficult to identify, pose integration challenges, divert the attention of management, disrupt our business, dilute shareholder value and adversely affect our business, financial condition and results of operations.

We operate in a highly competitive environment for mergers and acquisitions. We have in the past, and may in the future, seek to acquire or invest in businesses, joint ventures or technologies that we believe could complement or expand our platform, enhance our technical capabilities or otherwise offer growth opportunities. Although the significant majority of our revenue growth has been organic, we have completed several acquisitions since the year ended December 31, 2011, including the acquisition of Soomla Inc. in January 2021, and the acquisition of Luna Labs Limited in February 2021, among others, to further our goal of expanding our platform and abilities. Any such acquisition or investment may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable opportunities, whether or not the transactions are completed, and may result in unforeseen operating difficulties and expenditures. In particular, we may encounter difficulties assimilating or integrating the businesses, technologies, data, solutions, personnel or operations of any acquired companies, particularly if the key personnel of an acquired company choose not to work for us or face cultural challenges integrating with our company, or if their software or technology is not easily adapted to work with our platform, or we have difficulty retaining the customers of any acquired business due to changes in ownership, management or otherwise.

We could also face risks related to liability for activities of the acquired company as conducted before the acquisition, including intellectual property infringement claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities and litigation or other claims in connection with the acquired company, including claims from terminated employees, customers, users, former shareholders or other third parties, and our efforts to limit such liabilities could be unsuccessful. These transactions may also disrupt our business, divert our resources and require significant management attention that would otherwise be available for development of our existing business. Any such transactions that we are able to complete may not result in any synergies or other benefits we had expected to achieve, which could result in impairment charges that could be substantial. In addition, we may not be able to find and identify desirable acquisition targets or business opportunities or be successful in entering into an agreement with any particular strategic partner. These transactions could also result in dilutive issuances of equity securities or the incurrence of debt, contingent liabilities, amortization expenses, incremental operating expenses or the impairment of goodwill, any of which could materially and adversely affect our results of operations. Any such dilutive issuances of equity securities

47

may also draw us closer to violating the 25% Requirement for us or our shareholders as of the Spin-Off under the Spin-Off Ruling (see “—The recent Spin-Off of the assets of our Desktop business from ironSource Ltd. may give rise to potential liabilities for us in the event of a breach of our or our shareholders’ obligations under the agreements related to the Spin-Off or tax liabilities caused by the Spin-Off.”). In addition, if the resulting business from such a transaction fails to meet our expectations, our business, financial condition and results of operations may be materially and adversely affected or we may be exposed to unknown risks or liabilities.

Our operations are global in scope, creating a variety of operational and regulatory challenges.

Our operations are global in scope, with operations in Israel, the United States, the United Kingdom, China, South Korea, Japan, and India, in addition to a sales presence and customers in multiple other countries. We are continuing to adapt to and develop strategies to address global markets, but we cannot assure you that such efforts will be successful. We expect that our global activities will continue to grow for the foreseeable future as we continue to pursue opportunities in existing and new global industries, which will require the dedication of management attention and financial resources.

Our current and future global business and operations involve a variety of risks, including:

48

If we invest substantial time and resources to further expand our operations and are unable to do so successfully and in a timely manner, our business and results of operations will suffer.

We rely on our current understanding of regional regulatory requirements pertaining to the marketing, advertising and promotion of our solution suites, and any material change in such regulations, or a finding that we did not properly understand such regulations, may materially and adversely impact our business, financial condition and results of operations.

Some portions of our business rely extensively on marketing, advertising and promoting our individual products and solution suites requiring us to have an understanding of the local laws and regulations governing our business. In the event that we have relied on inaccurate information or advice, and engage in marketing, advertising or promotional activities that are not permitted, we may be subject to penalties, restricted from engaging in further activities or altogether prohibited from offering our solutions in a particular territory, all or any of which will adversely impact our business, financial condition and results of operations.

We may require additional capital to support the growth of our business, and this capital might not be available on acceptable terms, if at all.

While we have been profitable in the past, we cannot be certain that our operations will continue to generate sufficient cash to fully fund our ongoing operations or the growth of our business. We intend to continue to make investments to support our business and may require additional funds to respond to business challenges, including the need to develop new solutions or enhance our existing solutions, enhance our operating infrastructure, expand globally and acquire complementary businesses and technologies. Additional financing may not be available on terms favorable to us, if at all. In particular, the current COVID-19 pandemic has caused disruption in the global financial markets, which may reduce our ability to access capital and negatively affect our liquidity in the future. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could harm our business, financial condition and results or operations. We have entered into a credit facility with Silicon Valley Bank (the “Credit Agreement”) as the issuing lender together with other lenders, and these lenders’ rights will be senior to the rights of our shareholders. If

49

we incur any additional debt, the debt holders would have rights senior to holders of shares to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends on our shares. Furthermore, if we issue additional equity securities, our shareholders will experience dilution, and the new equity securities could have rights senior to those of our Class A ordinary shares. Because our decision to issue securities in the future will depend on numerous considerations, including factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future issuances of debt or equity securities. As a result, our shareholders bear the risk that future issuances of debt or equity securities may reduce the value of our Class A ordinary shares and dilute their interests. Our inability to obtain adequate financing on terms satisfactory to us when we require it could significantly limit our ability to continue to support our business growth, respond to business challenges, expand our operations or otherwise capitalize on our business opportunities due to lack of sufficient capital. Even if we are able to raise such capital, we cannot assure you that it will enable us to achieve better operating results or grow our business.

Fluctuations in currency exchange rates could harm our operating results and financial condition.

We offer our solution suites to customers globally and have operations in Israel, the United States, the United Kingdom, China, South Korea, Japan and India. Although the majority of our cash generated from revenue is denominated in U.S. dollars, most of our operating expenses are incurred in Israel and denominated in Israeli New Shekels (“NIS”). As a result, our consolidated U.S. dollar financial statements are subject to fluctuations due to changes in exchange rates as our operating expenses are translated from NIS into U.S. dollars. In particular, for the last two years ended December 31, 2020, there has been a significant decrease in the value of the U.S. dollar relative to the NIS, with the representative exchange rate having dropped from NIS 3.748 per U.S. dollar on December 31, 2018 to NIS 3.456 per U.S. dollar on December 31, 2019 to NIS 3.215 per U.S. dollar on December 31, 2020. If this trend continues, it could increase the U.S. dollar amount of our operating expenses significantly. Our financial results are also subject to changes in exchange rates that impact the settlement of transactions in non-local currencies. Because we conduct business in currencies other than U.S. dollars but report our results of operations in U.S. dollars, we also face remeasurement exposure to fluctuations in currency exchange rates, which could hinder our ability to predict our future results and earnings and could materially and adversely impact our financial condition and results of operations. To date, we have not engaged in currency hedging activities to limit the risk of exchange fluctuations and, as a result, our business, financial condition and results of operations could be materially and adversely affected by such fluctuations.

Seasonality may cause fluctuations in our sales and results of operations.

Our quarterly results of operations may vary significantly as a result of seasonal fluctuations during periods such as holidays, during which users spend increased time on entertainment, including games and mobile applications, which increases our customers’ usage of our advertising network and other solutions and may impact our revenue. We may also experience fluctuations due to factors that may be outside of our control that drive usage up or down. While we believe that this seasonality has affected and will continue to affect our quarterly results, our rapid growth has largely masked seasonal trends to date.

Our insurance may not provide adequate levels of coverage against claims or we may be unable to find insurance with sufficient coverage at a reasonable cost.

We believe that we maintain insurance customary for businesses of our size and type. However, there are types of losses we may incur that cannot be insured against or that we believe are not economically reasonable to insure. Moreover, if we do not make policy payments on a timely basis, we

50

could lose our insurance coverage, or if a loss is incurred that exceeds policy limits, our insurance provider could refuse to cover our claims, which could result in increased costs. If we are unable to make claims on our insurance, then we may be liable for any such claims, which could cause us to incur significant liabilities.

Further, insurance has become more expensive and difficult to find due to changes in the insurance market as well as the COVID-19 pandemic. Although we believe that we have adequate coverage, if we lose our insurance coverage and are unable to find similar coverage elsewhere or if rates continue to increase, it may have an adverse impact on our business, financial condition and results of operations.

Any legal proceedings, investigations or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome.

We are and may in the future become subject to legal proceedings, investigations and claims, including claims that arise in the ordinary course of business, such as claims brought by our customers or partners in connection with commercial disputes, claims by users, claims or investigations brought by regulators or employment claims made by our current or former employees.

We are not currently a party to any pending or, to our knowledge, threatened litigation that will have a significant effect on our financial position or profitability. Any litigation, investigation or claim, whether meritorious or not, could harm our reputation, will increase our costs and may divert management’s attention, time and resources, which may in turn harm our business, financial condition and results of operations. Insurance might not cover such claims, might not provide sufficient payments to cover all the costs to resolve one or more such claims, and might not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipated costs, potentially harming our business, financial position and results of operations.

Our business could be disrupted by catastrophic events.

Occurrence of any catastrophic event, including a global pandemic like the ongoing COVID-19 pandemic, earthquake, fire, flood, tsunami or other weather event, power loss, telecommunications failure, software or hardware malfunction, cyber-attack, war or terrorist attack, explosion or pandemic could impact our business. Our insurance coverage may not compensate us for losses that may occur in the event of an earthquake or other significant natural disaster. If any disaster were to occur, our ability to operate our business at our facilities could be impaired and we could incur significant losses, require substantial recovery time and experience significant expenditures in order to resume operations. If we are unable to develop adequate plans to ensure that our business functions continue to operate during and after a disaster and to execute successfully on those plans in the event of a disaster or emergency, our business would be harmed.

Our global operations may subject us to potential adverse tax consequences.

Our corporate structure and associated transfer pricing policies contemplate future growth in global markets, and consider the functions, risks and assets of the various entities involved in intercompany transactions. The amount of taxes we pay in different jurisdictions may depend on the application of the tax laws of the various jurisdictions, including Israel and the United States, to our global business activities, changes in tax rates, new or revised interpretations of existing tax laws and policies and our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. New or revised tax laws may also impact the amount of taxes we pay in different jurisdictions; for example, possible new standards could be introduced by authorities in the countries in which we operate that place greater emphasis on customer or end-user locations or

51

markets, may potentially result in increased tax liabilities. Furthermore, the tax authorities of jurisdictions in which we operate may challenge our methodologies for pricing intercompany transactions or disagree with our determinations as to the income or expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations. Our financial statements may fail to reflect adequate reserves to cover such a contingency.

Our Credit Agreement contains financial covenants and other restrictions on our actions that may limit our operational flexibility or otherwise adversely affect our results of operations.

The terms of our Credit Agreement include a number of covenants that limit our ability to, among other things, incur additional indebtedness, grant liens, merge or consolidate with other companies or sell substantially all of our assets, pay dividends and make certain distributions, each subject to important and significant exceptions and limitations. On June 29, 2021, the Company, as borrower, and certain of its subsidiaries, as guarantors, entered into a Credit Agreement (the “Credit Agreement”) with certain lenders from time party thereto (the “Lenders”) and Silicon Valley Bank, as administrative agent (the “Agent”) and L/C issuer, pursuant to which the Lenders extended to the Company a five- year senior secured revolving credit facility in an initial aggregate principal amount of up to $350.0 million, with the right, subject to certain conditions, to incur additional revolving commitments and/or incremental term loans in an amount not to exceed the sum of (i) $150.0 million plus (ii) additional amounts so long as the consolidated secured leverage ratio, on a pro forma basis after giving effect to such increase or incurrence, is no greater than or equal to 2.25:1.00.

The Credit Agreement will be secured by, substantially all of the assets of the Company and its material subsidiaries, and the equity interests therein. The terms of the Credit Agreement may restrict our current and future operations and could adversely affect our ability to finance our future operations or capital needs. In addition, complying with these covenants may make it more difficult for us to successfully execute our business strategy and compete against companies which are not subject to such restrictions.

A failure by us to comply with the covenants specified in the Credit Agreement, could result in an event of default under the agreement, which would give the lenders the right to terminate their commitments to provide additional loans under our revolving credit facility and to declare all borrowings outstanding, together with accrued and unpaid interest and fees, to be immediately due and payable. If the debt under our the Credit Agreement, were to be accelerated, we may not have sufficient cash or be able to borrow sufficient funds to refinance the debt or sell sufficient assets to repay the debt, which could immediately materially and adversely affect our business, cash flows, results of operations and financial condition.

RISKS RELATED TO REGULATION

We are subject to rapidly changing and increasingly stringent laws, contractual obligations and industry standards relating to privacy, data protection, data security and the protection of children. The restrictions and costs imposed by these requirements, or our actual or perceived failure to comply with them, could harm our business.

Our platform relies on our ability to collect, use and share information of customers, users and others. These activities are regulated by a variety of federal, state, local and international privacy, data protection and data security laws and regulations, which have become increasingly stringent in recent years.

52

Most jurisdictions in which we or our customers operate have adopted, or are in the process of adopting, privacy, data protection and data security laws. In this regard, it is important to highlight the General Data Protection Regulation 2016/679 (“GDPR”), which went into effect in May 2018. The GDPR regulates the collection, control, processing, sharing, disclosure and other use of data relating to personal data. Further to the UK’s exit from the EU on January 31, 2020, the GDPR ceased to apply in the UK at the end of the transition period on December 31, 2020. However, as of January 1, 2021, the UK’s European Union (Withdrawal) Act 2018 incorporated the GDPR (as it existed on December 31, 2020, but subject to certain UK specific amendments) into UK law (referred to as the “UK GDPR”). The UK GDPR and the UK Data Protection Act 2018 set out the UK’s data protection regime, which is independent from but aligned to the GDPR. The GDPR, UK GDPR and national implementing legislation in European Economic Area (“EEA”) member states and the UK, impose a strict data protection compliance regime including:

We are subject to the supervision of local data protection authorities in those EEA and UK jurisdictions where we are established or otherwise subject to the GDPR and the UK GDPR. Fines for certain breaches of the GDPR are significant, including fines up to the greater of €20 million or 4% of global turnover. In addition to the foregoing, a breach of the GDPR and the UK GDPR could result in regulatory investigations, reputational damage, orders to cease or change our processing of data, enforcement notices or assessment notices for a compulsory audit. We may also face civil claims including representative actions and other class action type litigation (where individuals have suffered harm), potentially amounting to significant compensation or damages liabilities, as well as associated costs, diversion of internal resources, and reputational harm.

The UK GDPR mirrors the fines under the GDPR including fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. These changes will lead to additional costs and increase our overall risk exposure.

53

As described in “—We are subject to laws and regulations worldwide, many of which are unsettled and still developing and which could increase our costs or materially and adversely affect our business,” recent decisions by the Court of Justice of the European Union, recent guidance from European data protection authorities and a new proposed ePrivacy Regulation, may further restrict our use of online tracking technologies which our solutions rely on. We have, at times, been subject to enquiries about our compliance with the GDPR, and we may also be subject to such enquiries and complaints in the future.

U.S. privacy and data security laws are also complex and changing rapidly. Many states have enacted laws regulating the online collection, use and disclosure of personal information and requiring companies implement reasonable data security measures. Laws in all states and U.S. territories also require businesses to notify affected individuals, governmental entities and/or credit reporting agencies of the occurrence of certain security breaches affecting personal information. These laws are not consistent, and compliance with them in the event of a widespread data breach is complex and costly.

States have also begun to introduce more comprehensive privacy legislation. For example, California enacted the CCPA, which took effect on January 1, 2020 and became enforceable by the California Attorney General on July 1, 2020. The CCPA creates new individual privacy rights for California consumers (as defined in the law) and places increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of sale of their personal information, and receive detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action may increase the likelihood of, and risks associated with data breach litigation. In addition to increasing our compliance costs and potential liability, the CCPA created restrictions on “sales” of personal information that may restrict the disclosure of personal information for advertising purposes. Our advertising business relies, in part, on such disclosure and could be materially and adversely affected by the CCPA’s restrictions.

We will also be subject to the forthcoming CPRA, which was passed into law on November 3, 2020 but will not take substantial effect until January 1, 2023. The CPRA imposes additional obligations on companies covered by the legislation and will significantly modify the CCPA, including by expanding consumers’ rights with respect to certain sensitive personal information, such as increasing regulation on online advertising and particularly cross-context behavioral advertising. The CPRA also creates a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA. The CPRA potentially results in further uncertainty and requires us to incur additional costs and expenses in an effort to comply.

Certain other state laws impose similar privacy obligations. We also expect that more states may enact legislation similar to the CCPA, which provides consumers with new privacy rights and increases the privacy and security obligations of entities handling certain personal information of such consumers. The CCPA has prompted a number of proposals for a new federal and state-level privacy legislation. Such proposed legislation, if enacted, may add additional complexity, variation in requirements, restrictions and potential legal risk, require additional investment of resources in compliance programs, impact strategies and the availability of previously useful data and could result in increased compliance costs and/or changes in business practices and policies.

Additionally, in August 2021, the National People’s Congress of the People’s Republic of China adopted the Personal Information Protection Law (“PIPL”), which will take effect on November 1, 2021. The PIPL introduces protections and obligations with respect to the handling of personal information that are similar to those imposed by the GDPR and marks the introduction of a comprehensive system for the protection of personal information in China. We cannot yet determine the impact that the PIPL

54

may have on our business; however, we may incur expenses in complying with any new obligations, we could be subject to significant fines if we are found to not comply with the PIPL and we may be required to make certain changes in our business operations and product and services development as they relate to China.

Data privacy legislation restricts the cross-border transfer of personal data and some countries introduced data localization into their laws. Specifically, the GDPR, the UK GDPR and other European and UK data protection laws generally prohibit the transfer of personal data from the EEA, the UK and Switzerland, to the United States and most other countries unless the transfer is to an entity established in a country deemed to be provide adequate protection (such as Israel) or the parties to the transfer have implemented specific safeguards to protect the transferred personal data. Where we transfer personal data outside the EEA or the UK to a country that is not deemed to be “adequate,” we ensure we comply with applicable laws including where we can rely on derogations (e.g. where the transfer is necessary for the performance of a contract) or we may put in place standard contractual clauses. We have previously also relied on relevant third parties’ Privacy Shield certifications.

Recent legal developments in the EU have created complexity and uncertainty regarding transfers of personal data from the EEA to the United States. Most recently, on July 16, 2020, in a case known as Schrems II, the Court of Justice of the European Union (“CJEU”) invalidated the EU-US Privacy Shield Framework (“Privacy Shield”) under which personal data could be transferred from the EEA to U.S. entities who had self-certified under the Privacy Shield scheme. While the CJEU upheld the adequacy of the standard contractual clauses (a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism, and potential alternative to the Privacy Shield), it made clear that reliance on them alone may not necessarily be sufficient in all circumstances. Use of the standard contractual clauses must now be assessed on a case-by-case basis taking into account the legal regime applicable in the destination country, in particular applicable surveillance laws and rights of individuals and additional measures and/or contractual provisions may need to be put in place, however, the nature of these additional measures is currently uncertain. The CJEU went on to state that if a competent supervisory authority believes that the standard contractual clauses cannot be complied with in the destination country and the required level of protection cannot be secured by other means, such supervisory authority is under an obligation to suspend or prohibit that transfer. Partly as a result of the CJEU decision, the European Commission has published revised standard contractual clauses for data transfers from the EEA: the revised clauses must be used for relevant new data transfers from September 27, 2021; existing standard contractual clauses arrangements must be migrated to the revised clauses by December 27, 2022. There is some uncertainty around whether the revised clauses can be used for all types of data transfers, particularly whether they can be relied on for data transfers to non-EEA entities subject to the GDPR. The revised standard contractual clauses apply only to the transfer of personal data outside of the EEA and not the UK; the UK’s Information Commissioner’s Office launched a public consultation on its draft revised data transfers mechanisms in August 2021, and we are monitoring the outcome of this.

There are few viable alternatives to the Standard Contractual Clauses, and the law in this area remains dynamic. These recent developments will require us to review and may require us to amend the legal mechanisms by which we make and/or receive personal data transfers to/in the United States. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, where the revised standard contractual clauses must be implemented, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we provide our solutions, the geographical location or segregation of our relevant systems and operations, may reduce demand for our solutions from companies subject to EU or UK data protection laws and could materially and adversely affect our financial results.

55

Additionally, other countries outside of the EU have enacted or are considering enacting similar cross-border data transfer restrictions and laws requiring local data residency, which could increase the cost and complexity of delivering our solutions and operating our business.

In addition, we are also subject to the Israeli Privacy Protection Law 5741-1981 (the “PPL”), and its regulations, including the Israeli Privacy Protection Regulations (Data Security) 2017 (the “Data Security Regulations”), which came into effect in Israel in May 2018 and impose obligations with respect to the manner personal data is processed, maintained, transferred, disclosed, accessed and secured, as well as the guidelines of the Israeli Privacy Protection Authority. In this respect, the Data Security Regulations may require us to adjust our data protection and data security practices, information security measures, certain organizational procedures, applicable positions (such as an information security manager) and other technical and organizational security measures. Failure to comply with the PPL, its regulations and guidelines issued by the Israeli Privacy Protection Authority, may expose us to administrative fines, civil claims (including class actions) and in certain cases criminal liability. Current pending legislation may result in a change of the current enforcement measures and sanctions. The Israeli Privacy Protection Authority may initiate administrative inspection proceedings from time to time without any suspicion of any particular breach of the PPL, as the Israeli Privacy Protection Authority has done in the past with respect to dozens of Israeli companies in various business sectors. In addition, to the extent that any administrative supervision procedure is initiated by the Israeli Privacy Protection Authority that reveals certain irregularities with respect to our compliance with the PPL, we may need to take certain remedial actions to rectify such irregularities, which may increase our costs, but may also be exposed to administrative fines, civil claims (including class actions) and in certain cases, criminal liability.

Children’s privacy has been a focus of recent enforcement activity under longstanding privacy laws as well as privacy and data protection laws enacted in recent years. EU and UK regulators focus, among other things, on the processing of personal data relating to children, with increased enforcement pending as well as additional guidance. The Federal Trade Commission and state attorneys general have, in recent years, increased enforcement of the Children’s Online Privacy Protection Act (“COPPA”), which requires companies to obtain parental consent before collecting personal information from children under the age of 13 for purposes not permitted by COPPA. COPPA also sets forth, among other things, a number of restrictions related to what information may be collected with respect to children under the age of 13. In addition, the GDPR and UK GDPR address the processing of children’s personal data, and specifically require that if processing of personal data of individuals is based on such individuals’ consent, and such individuals are children under the age of 13 to 16 (depending on the specific legislation of the UK or each EU member state), parental consent must be obtained. In addition, the U.K.’s Information Commissioner’s Office enacted the Age Appropriate Design Code (“Children’s Code”), which became enforceable on September 2, 2021, and imposes various obligations relating to the processing of children’s data. In addition, the CCPA requires companies to obtain the consent of children in California under 16 (or parental consent for children under 13) before selling their personal information. We have been subject to claims related to the privacy of minors predicated on COPPA and other privacy laws, and we may in the future face claims under COPPA, the GDPR, the UK GDPR, the Children’s Code, the CCPA or other laws relating to children’s privacy.

Apart from the requirements of privacy, data protection and data security laws, we have obligations relating to privacy, data protection and data security under our published policies and documentation, contracts and applicable industry standards. Although we endeavor to comply with these obligations, we may have failed to do so in the past and may be subject to allegations that we have failed to do so or have otherwise processed data improperly. We could be subject to enforcement

56

action or litigation alleging that our methods of data collection or our other data processing practices violate our published policies, federal or state laws prohibiting unfair or deceptive business practices or other privacy laws.

In response to the increasing restrictions of global privacy and data security laws, our customers have sought and may continue to seek increasingly stringent contractual assurances regarding our handling of personal information, and may adopt internal policies that limit their use of our platform. In addition, privacy advocates and industry groups have regularly proposed, and may propose in the future, self-regulatory standards upon which we may be legally or contractually bound. If we fail to comply with these contractual obligations or standards, we may face substantial contractual liability or fines.

Various jurisdictions around the world continue to propose new laws that regulate the privacy and/or security of certain types of personal data. Complying with these laws, if enacted, would require significant resources and leave us vulnerable to possible fines and penalties if we are unable to comply. Our obligations under privacy and data security laws, our contracts and applicable industry standards (including requirements by operating system platforms or app stores) are increasing, becoming more complex and changing rapidly, which has increased and may continue to increase the cost and effort required to comply with them. The privacy and data security compliance challenges we and our customers face in the EU, the UK, the United States and other jurisdictions may also limit our ability to operate, or offer certain product features, in those jurisdictions, which could reduce demand for our solutions from customers subject to their laws. We may also be required to adapt our solutions in order to comply with changing regulations. Despite our efforts, we may not be successful in achieving compliance with these rapidly-evolving requirements. We could be perceived to be in non-compliance with applicable privacy laws, especially when acquiring new companies and before we have completed our gap analysis and remediation. Any actual or perceived non-compliance could result in litigation and proceedings against us by governmental entities, customers, individuals or others; fines and civil, criminal or administrative penalties for us or company officials; obligations to cease offering or to substantially modify our solutions in ways that make them less effective in certain jurisdictions; negative publicity; harm to our brand and reputation and reduced overall demand for our solutions or reduced revenue. Such occurrences could materially and adversely affect our business, financial condition and results of operations.

We are subject to laws and regulations worldwide, many of which are unsettled and still developing and which could increase our costs or materially and adversely affect our business.

We are subject to a variety of laws internationally that affect our business, including laws regarding consumer protection, advertising, electronic marketing, protection of minors, data protection and privacy, data localization requirements, online services, anti-competition, labor, real estate, taxation, intellectual property ownership and infringement, tax, export and national security, tariffs, anti-corruption and telecommunications, all of which are continuously evolving and developing. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting and compliance with laws, regulations and similar requirements may be burdensome and expensive. Laws and regulations may be inconsistent from jurisdiction to jurisdiction, which may increase the cost of compliance and doing business. Any such costs, which may rise in the future as a result of changes in these laws and regulations or in their interpretation, could make any of our solutions less attractive to our customers or cause us to change or limit our ability to sell our solutions. We have policies and procedures designed to ensure compliance with applicable laws and regulations, but we cannot assure you that our employees, contractors or agents will not violate such laws and regulations or our policies and procedures.

57

In particular, as a result of the global and advertising technology focused nature of our business, we are potentially subject to a number of laws and regulations that affect the offering of certain types of content, such as that which depicts violence, many of which are ambiguous, still evolving and could be interpreted in ways that could harm our business or expose us to liability. In addition, there are ongoing academic, political and regulatory discussions in the United States, the EU, the UK, Australia and other jurisdictions regarding whether certain game mechanisms, such as “loot boxes,” and game genres should be subject to a higher level or different type of regulation than other game genres or mechanics to protect consumers, in particular minors and persons susceptible to addiction, and, if so, what such regulation should include. For example, in December 2017, Apple updated its terms of service to require publishers of applications that include loot boxes to disclose the odds of receiving each type of item within each loot box to customers prior to purchase. Google similarly updated its terms of service in May 2019. In the event that Apple, Google, or any other Provider changes its developer terms of service to include more onerous requirements or if any Provider were to prohibit the use of loot boxes, or similar monetization products, in games distributed in apps, our customers would be required to redesign the economies of their affected games, which would harm our customers and could negatively impact our revenue.

Further, new regulation by the U.S. federal government and its agencies, such as the Federal Trade Commission, U.S. states and state agencies or foreign jurisdictions, interpretations of such regulations and enforcement actions by federal and state agencies which may vary significantly across jurisdictions, could require that certain game content, including advertising, be modified or removed from games, increase the costs of operating our solutions or our customer’s games and apps, impact user engagement and thus the functionality and effectiveness of our solutions or otherwise harm our business performance.

It is difficult to predict how existing or new laws may be applied. If we become liable, directly or indirectly, under these laws or regulations, we could be harmed, and we may be forced to implement new measures to reduce our exposure to this liability. This may require us to expend substantial resources or to modify our solutions, which would harm our business, financial condition and results of operations. In addition, the increased attention focused upon liability issues as a result of lawsuits and legislative proposals could harm our reputation or otherwise impact the growth of our business. Any costs incurred as a result of this potential liability could harm our business, financial condition or results of operations.

In addition, in the EU, Directive 2002/58/EC (as amended by Directive 2009/136/EC), commonly referred to as the ePrivacy Directive, directs EU member states to ensure that accessing information stored on an Internet user’s computer or device, such as device identifiers and other similar technologies, is allowed only if the user has been informed about such access and, depending on the nature of the technology, given his or her consent. The ePrivacy Directive has generally been given effect to by national laws in the EU (“EU ePrivacy Laws”). A recent ruling by the CJEU clarified that such consent must be reflected by an affirmative act of the user, and EU and UK regulators are increasingly focusing on compliance with requirements in the online digital advertising ecosystem, as evidenced by recent announcements of significant fines relating to the use of cookies. The GDPR also imposes further conditions on obtaining valid consent, which applies to the processing of personal data. A replacement for the ePrivacy Directive is currently under discussion by EU member states to complement and bring electronic communication services in line with the GDPR and force a harmonized approach across EU member states. Like the GDPR, the proposed ePrivacy Regulation has extra-territorial application as it applies to businesses established outside the EU who provide publicly available electronic communications services to, or gather data from the devices of, users in the EU. Though still subject to debate, the proposed ePrivacy Regulation may further raise the bar for the collection of device identifiers, and the fines and penalties for breach may be significant. We may be required to, or otherwise may determine that it is advisable to, make significant changes in our business operations and platform to obtain user opt-in for the collection of device identifiers or develop

58

or obtain additional tools and technologies to compensate for a lack of device identifiers, in compliance with the ePrivacy Directive. In addition, further to the UK’s exit from the EU on December 31, 2021, access to a user’s technical information (as described above in this paragraph) will be subject to local UK laws (i.e. The Privacy and Electronic Communications Regulations 2003 (“PECR”)). Also, the UK has implemented laws around the collection of user technical information under the UK GDPR which are closely aligned with EU privacy laws.

As the collection and use of data for digital advertising has received media attention over the past several years, some government regulators, such as the U.S. Federal Trade Commission, and privacy advocates have suggested creating a “Do Not Track” standard that would allow Internet users to express a preference, independent of cookie settings in their browser, not to have their online browsing activities tracked. “Do Not Track” has seen renewed emphasis since passage of the CCPA as its regulations contemplate browser-based or similar “Do Not Sell” signals. If a “Do Not Track,” “Do Not Sell” or similar control is adopted by many Internet users or if a “Do Not Track” standard is imposed by state, federal or foreign legislation, or is agreed upon by standard setting groups, we may have to change our business practices, our clients may reduce their use of our platform, and our business, financial condition and results of operations could be materially and adversely affected. Additionally, once the CPRA is in effect, if consumers increase their usage of “Do Not Sell” signals, this would reduce our ability to use their data for certain advertising purposes, and as a result our clients may reduce their use of our platform, and our business, financial condition and results of operations could be materially and adversely affected.

Increased transparency into the collection and use of data for digital advertising introduced both through features in devices and regulatory requirements, such as the GDPR, UK GDPR, the CCPA and EU ePrivacy laws and the UK’s PECR, as well as compliance with such requirements, may create operational burdens to implement and may lead more users to block the collection and use of data about them.

It is also possible that a number of laws and regulations may be adopted or construed to apply to us or our customers in the United States and elsewhere that could restrict the online and mobile industries, including user privacy, advertising, taxation, content suitability, copyright, distribution and antitrust, and our solutions or components thereof may be deemed or perceived illegal or unfair practices. Furthermore, the growth and development of in-app advertisement and mobile monetization strategies may prompt calls for more stringent consumer protection laws that may impose additional burdens on companies such as us and our customers conducting business through the Internet and mobile devices. We anticipate that scrutiny and regulation of our industry will increase and we will be required to devote legal and other resources to addressing such regulation. For example, existing laws or new laws regarding the marketing of in-app purchases, labeling of free-to-play games or regulation of currency, banking institutions, unclaimed property or money transmission may be interpreted to cover games made with, or utilizing, our solutions and the revenue that we receive from our solutions. If that were to occur, we may be required to seek licenses, authorizations or approvals from relevant regulators, the granting of which may be dependent on us meeting certain capital and other requirements, and we may be subject to additional regulation and oversight, all of which could significantly increase our operating costs.

In addition, any failure or perceived failure by us to comply with any laws, regulatory requirements, legal obligations, or policies relating to privacy, data protection, data security, or consumer protection may result in governmental investigations or enforcement actions, litigation, claims, or public statements against us by consumer advocacy groups, or others, and could result in significant liability and otherwise materially and adversely affect our reputation and business. The cost of compliance with, and other burdens imposed by, the laws, regulations, other obligations, and policies that are applicable to the businesses of our users may limit the adoption and use of, and

59

reduce the demand for, our solutions. Additionally, if third parties we work with violate applicable laws, regulations or contractual obligations, such violations may put our users’ data at risk, could result in governmental investigations or enforcement actions, fines, litigation, claims, or public statements against us by consumer advocacy groups or others, and could result in significant liability and otherwise materially and adversely affect our reputation and business. Further, public scrutiny of, or complaints about, technology companies or their data handling or data protection practices, even if unrelated to our business, industry or operations, may lead to increased scrutiny of technology companies, including us, and may cause government agencies to enact additional regulatory requirements, or to modify their enforcement or investigation activities, which may increase our costs and risks. Any of the foregoing could materially and adversely affect our business, financial condition and results of operations.

Further, governmental agencies in any of the countries in which we, our customers or users are located, such as China, could choose to block access to or require a license for our platform, any of our solutions, our website, our customers’ mobile applications, third-party operating system platforms and app stores that we depend upon to operate our solutions or the Internet generally for a number of reasons, including security, confidentiality or regulatory concerns. Users generally need to access the Internet and also platforms, such as the Apple App Store and the Google Play Store, to play games published or operated using our solutions. In addition, companies may adopt policies that prohibit their employees from accessing our solutions that users need in order to play games created or operated using our platform. If companies or governmental entities block, limit or otherwise restrict customers from accessing our solutions or users from playing games published or advertised on our platform, our business could be negatively impacted, our customers’ users could decline or grow more slowly, and our financial condition and results of operations could be materially and adversely affected.

Adapting to these and similar changes has in the past and may in the future require significant time, resources and expense, which may lessen the growth of mobile apps and gaming, as well as increase our costs of operation or limit our ability to operate or expand our business. Failure to comply with the applicable regulatory requirements could also result in regulatory investigations, reputational damage, orders to cease or change our processing of data, enforcement notices or assessment notices for a compulsory audit. We may also face civil claims including representative actions and other class action type litigation (where individuals have suffered harm), potentially amounting to significant compensation or damages liabilities, as well as associated costs, diversion of internal resources and reputational harm, any of which could materially and adversely affect our business, financial condition and results of operations.

We are subject to anti-corruption, anti-bribery, anti-money laundering, economic and trade sanctions and similar laws, and non-compliance with such laws can subject us to criminal or civil liability and harm our business, financial condition and results of operations.

We may be subject to certain economic and trade sanctions laws and regulations, export control and import laws and regulations, including those that are administered by the U.S. Department of Treasury’s Office of Foreign Assets Control (“OFAC”), the U.S. Department of State, the U.S. Department of Commerce, the United Nations Security Council and other relevant governmental authorities.

We are also subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), the United Kingdom Bribery Act 2010, Chapter 9 (sub-chapter 5) of the Israeli Penal Law, 57373-1977, the Israeli Prohibition on Money Laundering Law, 5760-2000 and other anti-bribery laws in countries in which we conduct our activities. These laws generally prohibit companies, their employees and third-party intermediaries from authorizing, promising, offering, providing, soliciting or accepting, directly or indirectly, improper payments or benefits to or from any person whether in the public or private sector.

60

In addition, the FCPA’s accounting provisions require us to maintain accurate books and records and a system of internal accounting controls. We have policies, procedures, systems, and controls designed to promote compliance with applicable anti-corruption laws.

As we increase our global sales and business, we may engage with business partners and third-party intermediaries to market our solutions and obtain necessary permits, licenses and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not authorize such activities.

Our customers may have users in countries that are subject to U.S. economic sanctions laws and regulations administered by OFAC, the Israeli Trade with the Enemy Ordinance, 1939 and sanction laws of the EU and other applicable jurisdictions, which may prohibit the sale of products or provision of services to embargoed jurisdictions (“Sanctioned Countries”) or sanctioned parties. We have taken steps to avoid having customers in Sanctioned Countries and have implemented various control mechanisms designed to prevent unauthorized dealings with Sanctioned Countries or sanctioned parties going forward. Although we have taken precautions to prevent our solutions from being provided, deployed or used in violation of sanctions laws, due to the remote nature of our solutions and the potential for manipulation using VPNs, we cannot assure you that our policies and procedures relating to sanctions compliance will prevent any violations in the future. If we are found to be in violation of any applicable sanctions regulations, it can result in significant fines or penalties and possible incarceration for responsible employees and managers, as well as reputational harm and loss of business.

Despite our compliance efforts and activities, there can be no assurance that our employees or representatives will comply with the relevant laws and we may be held responsible. Non-compliance with anti-corruption, anti-money laundering, export control, economic and trade sanctions and other trade laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas or investigations are initiated, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition and results of operations could be materially harmed. Responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In addition, regulatory authorities may seek to hold us liable for successor liability for violations committed by companies in which we invest or that we acquire. As a general matter, enforcement actions and sanctions could harm our business, financial condition and results of operations.

Our amended and restated articles of association provide that unless we consent to an alternate forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any claims arising under the Securities Act, which may limit the ability of our shareholders to initiate litigation against us or increase the cost thereof.

Our amended and restated articles of association provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any claims arising under the Securities Act. Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions, and accordingly, both state and federal courts have jurisdiction to entertain such claims. While the federal

61

forum provision in our amended and restated articles does not restrict the ability of our shareholders to bring claims under the Securities Act, we recognize that it may limit shareholders’ ability to bring a claim in the judicial forum that they find favorable and may increase certain litigation costs, which may discourage the filing of claims under the Securities Act against the Company, its directors and officers. However, the enforceability of similar forum provisions (including exclusive federal forum provisions for actions, suits or proceedings asserting a cause of action arising under the Securities Act) in other companies’ organizational documents has been challenged in legal proceedings, and there is uncertainty as to whether courts would enforce the exclusive forum provisions in our amended and restated articles of association. If a court were to find the choice of forum provision contained in our amended and restated articles of association to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially adversely affect our business, financial condition and results of operations.

RISKS RELATED TO INTELLECTUAL PROPERTY MATTERS

If we fail to adequately maintain, protect or enforce our intellectual property rights, our competitive position could be impaired and we may lose valuable assets, generate reduced revenue, and incur costly litigation to protect our rights.

Our success is dependent, in part, upon protecting our intellectual property rights, including those in our proprietary know-how and technology. We rely on a combination of copyrights, trade secret and other intellectual property laws as well as contractual restrictions to establish and protect our intellectual property rights. While it is our policy to protect and defend our rights to our intellectual property, we cannot predict whether steps taken by us will be adequate to prevent infringement, misappropriation or other violation of our intellectual property rights.

While software and other of our proprietary works may be protected under copyright law, we have not registered any copyrights in these works, and instead, primarily rely on protecting our software as a trade secret. In order to bring a copyright infringement lawsuit in the United States, the copyright must be registered. Accordingly, the remedies and damages available to us for unauthorized use of our software may be limited.

Policing unauthorized use of our know-how, technology and intellectual property is difficult, costly, time-consuming and may not be effective. Third parties may knowingly or unknowingly infringe our proprietary rights. In addition, third parties may challenge proprietary rights held by us, and our pending and future trademark and patent applications may not be approved. These claims may result in restrictions on our use of our intellectual property or the conduct of our business. In any of these cases, we may be required to expend significant time and expense to prevent infringement or to enforce our rights.

Although we attempt to protect our intellectual property, technology and confidential information by entering into confidentiality and invention assignment agreements with our employees and consultants and entering into confidentiality agreements with the parties with whom we share our confidential information, these agreements may not effectively grant all necessary rights to any inventions that may have been developed by the employees or consultants party thereto, and may not be effective in controlling access to and distribution of our solutions or technology, and our confidential information or provide an adequate remedy in the event of unauthorized use of our solutions or technology or unauthorized access, use or disclosure of our confidential information. Some of the provisions of our agreements that protect us against unauthorized use, copying, transfer, and disclosure of our solutions, may be unenforceable under the laws of certain jurisdictions and foreign countries. Further, these agreements do not prevent our competitors from independently developing technologies that are substantially equivalent or superior to ours. We cannot guarantee that others will

62

not independently develop technology with the same or similar functions to any proprietary technology we rely on to conduct our business and differentiate ourselves from our competitors. Unauthorized parties may also attempt to copy or obtain and use our technology to develop applications with the same functionality as our solutions. Any unauthorized disclosure or use of our trade secrets or other confidential proprietary information could make it more expensive to do business, thereby harming our operating results.

Circumstances outside our control could also pose a threat to our intellectual property rights. For example, effective intellectual property protection may not be available in the United States or other countries from which our product offerings or platforms are accessible. Changes in the law or adverse court rulings may also negatively affect our ability to prevent others from using our technology. In addition, changes in the law or adverse court rulings in countries where we have outsourced research and development centers may affect our intellectual property rights, including with respect to ownership, distribution and use of such intellectual property.

Any significant impairment of our intellectual property rights could harm our business or our ability to compete. Furthermore, if we are unable to protect our proprietary rights or prevent unauthorized use, infringement or misappropriation by third parties, the value of our brand and other intangible assets may be diminished, and competitors may be able to more effectively mimic our offerings and service. We may be required to incur significant expenses in registering, monitoring and protecting our intellectual property rights. Any litigation could result in significant expense to us, including the diversion of management’s time, and may not ultimately be resolved in our favor. Any of these events could seriously harm our business.

We may become subject to intellectual property disputes, which are costly and may subject us to significant liability and increased costs of doing business.

There is considerable intellectual property development and enforcement activity in our industry. We expect that app developers in our industry will increasingly be subject to infringement claims as the number of competitors grows and the functionality of platforms, products and services in different industries overlap. Our future success depends in part on not infringing upon or misappropriating the intellectual property rights of others. There is a risk that our operations, platform or individual solutions, whether created in-house or purchased from time to time through mergers or acquisitions, may infringe or otherwise violate, or be alleged to infringe or otherwise violate, the intellectual property rights of third parties. If we were subject to a claim of infringement, regardless of the merit of the claim or our defenses, the claim could:

Any of the foregoing could materially and adversely affect our business, prospects, financial condition and results of operations.

63

Our platform contains third-party open source software components, which may pose particular risks to our proprietary software, technologies and solutions in a manner that could negatively affect our business.

Our platform contains software modules by third-party authors that are publicly available under “open source” licenses, and we expect to use open source software in the future. We have engaged a third-party software solution to assist with managing our use of open source software, including tracking the use of open source in our platform, monitoring license compliance and compliance with our open source policy. However, we could still be subjected to claims of infringement and other possible action. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide support, warranties, indemnification or other contractual protections regarding infringement claims or the quality of the code. To the extent that our platform depends upon the successful operation of open source software, any undetected errors or defects in this open source software could prevent the deployment or impair the functionality of our platform, delay introductions of new solutions, result in a failure of any of our solutions and injure our reputation. For example, undetected errors or defects in open source software could render it vulnerable to breaches or security attacks, and, in conjunction, make our systems more vulnerable to data breaches. In addition, the public availability of such software may make it easier for others to compromise our platform.

Some open source licenses contain requirements that we make available source code for modifications or derivative works we create based upon the type of open source software we use, or grant other licenses to our intellectual property. If we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. While our open source policy and third-party software solution are meant to prevent such misuse, there can be no assurance that such incidents would not occur. This would allow our competitors to create similar offerings with lower development effort and time and ultimately could result in a loss of our competitive advantages. Alternatively, to avoid the public release of the affected portions of our source code, we could be required to expend substantial time and resources to re-engineer some or all of our software.

Although we monitor our use of open source software to avoid subjecting our platform to conditions we do not intend, there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to provide or distribute our solutions. From time to time, there have been claims challenging the ownership of open source software against companies that incorporate open source software into their products or platforms. As a result, we could be subject to lawsuits by parties claiming ownership of what we believe to be open source software. Moreover, we cannot assure you that our processes for controlling our use of open source software in our platform will be effective. If we are held to have breached or failed to fully comply with all the terms and conditions of an open source software license, we could face infringement or other liability, or be required to seek costly licenses from third parties to continue providing our solutions on terms that are not economically feasible, to re-engineer our solutions, to discontinue or delay the provision of our solutions if re-engineering could not be accomplished on a timely basis or to make generally available, in source code form, our proprietary code, any of which could materially and adversely affect our business, financial condition and results of operations.

RISKS RELATED TO OUR CLASS A ORDINARY SHARES AND THIS OFFERING

Sales of a substantial number of our securities in the public market by the Selling Securityholders and/or by our existing securityholders could cause the price of our ordinary shares to fall.

The Selling Securityholders can sell, under this prospectus, up to 102,869,375 Class A ordinary shares constituting approximately 10.1% of our issued and outstanding ordinary shares. Sales of a

64

substantial number of Class A ordinary shares in the public market by the Selling Securityholders and/ or by our other existing securityholders, or the perception that those sales might occur, could depress the market price of our ordinary shares and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our Class A ordinary shares.

The price of our Class A ordinary shares may be volatile, and the value of our Class A ordinary shares may decline.

We cannot predict the prices at which our Class A ordinary shares will trade. The market price of our Class A ordinary shares may fluctuate substantially and may be lower than the current market price. In addition, the trading price of our Class A ordinary shares is likely to be volatile and could be subject to fluctuations in response to various factors, some of which are beyond our control. These fluctuations could cause you to lose all or part of your investment in our Class A ordinary shares as you might be unable to sell your shares at or above the price you paid. Factors that could cause fluctuations in the trading price of our Class A ordinary shares include the following:

Broad market and industry fluctuations, as well as general economic, political, regulatory and market conditions, may also negatively impact the market price of our Class A ordinary shares. In addition, technology stocks have historically experienced high levels of volatility. In the past,

65

companies who have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future, which could result in substantial expenses and divert our management’s attention.

An active public trading market may not develop or be sustained for our Class A ordinary shares.

An active public trading market for our Class A ordinary shares may not develop or, if developed, it may not be sustained. The lack of an active market may impair your ability to sell your Class A ordinary shares at the time you wish to sell them or at a price that you consider reasonable. The lack of an active market may also reduce the fair value of your Class A ordinary shares. An inactive market may also impair our ability to raise capital to continue to fund operations by selling Class A ordinary shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

The dual class structure of our ordinary shares may adversely affect the trading market for our Class A ordinary shares.

We cannot predict whether our dual class structure will result in a lower or more volatile market price of our Class A ordinary shares or in adverse publicity or other adverse consequences. For example, certain index providers have announced restrictions on including companies with dual class or multi-class share structures in certain of their indexes. In July 2017, S&P Dow Jones and FTSE Russell announced changes to their eligibility criteria for the inclusion of shares of public companies on certain indices, including the Russell 2000, the S&P 500, the S&P MidCap 400 and the S&P SmallCap 600, to exclude companies with multiple classes of shares from being added to these indices. Beginning in 2017, MSCI, a leading stock index provider, opened public consultations on their treatment of no-vote and multi-class structures and temporarily barred new multi-class listings from certain of its indices; however, in October 2018, MSCI announced its decision to include equity securities “with unequal voting structures” in its indices and to launch a new index that specifically includes voting rights in its eligibility criteria. As a result, our dual class capital structure would make us ineligible for inclusion in any of these indices, and mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track these indices will not be investing in our Class A ordinary shares. These policies are still fairly new and it is as of yet unclear what effect, if any, they will have on the valuations of publicly traded companies excluded from the indices, but it is possible that they may depress these valuations compared to those of other similar companies that are included. Furthermore, we cannot assure you that other stock indices will not take a similar approach to S&P Dow Jones or FTSE Russell in the future. Exclusion from indices could make our Class A ordinary shares less attractive to investors and, as a result, the market price of our Class A ordinary shares could be adversely affected.

The dual class structure of our ordinary shares has the effect of concentrating voting power with our management and other pre-listing shareholders, which will limit your ability to influence the outcome of important transactions, including a change in control.

Our Class B ordinary shares have five votes per share, and our Class A ordinary shares have one vote per share. Members of our management collectively hold approximately 28% of the voting power of our outstanding ordinary shares, and our other shareholders that pre-existed the public listing (“pre-listing shareholders”) collectively hold approximately 62% of the voting power of our outstanding ordinary shares. Accordingly, although there are no voting agreements among members of our management or between them and other shareholders, our management and other pre-listing shareholders together hold all of our issued and outstanding Class B ordinary shares and therefore, individually or together, are able to significantly influence matters submitted to our shareholders for approval, including the election of directors, amendments of our organizational documents and any

66

merger or other major corporate transactions that require shareholder approval. Our management and other pre-listing shareholders, individually or together, may vote in a way with which you disagree and which may be adverse to your interests. This concentrated voting power may have the effect of delaying, preventing or deterring a change in control of our Company, could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might ultimately adversely affect the market price of our Class A ordinary shares. Future transfers by the holders of Class B ordinary shares will result in those shares converting into Class A ordinary shares, subject to limited exceptions. For information about our dual class structure, see “Description of Share Capital and Articles of Association.”

If we do not meet the expectations of equity research analysts, if they do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our Class A ordinary shares, the price of our Class A ordinary shares could decline.

The trading market for our Class A ordinary shares will rely in part on the research and reports that equity research analysts publish about us and our business. The analysts’ estimates are based upon their own opinions and are often different from our estimates or expectations. If our results of operations are below the estimates or expectations of public market analysts and investors, the price of our Class A ordinary shares could decline. Moreover, the price of our Class A ordinary shares could decline if one or more securities analysts downgrade our Class A ordinary shares or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Our issuance of additional share capital in connection with financings, acquisitions, investments, our equity incentive plans or otherwise will dilute all other shareholders.

We expect to issue additional share capital in the future that will result in dilution to all other shareholders. We expect to grant equity awards to employees and directors under our equity incentive plans. We may also raise capital through equity financings in the future. As part of our business strategy, we may acquire or make investments in companies, solutions or technologies and issue equity securities to pay for any such acquisition or investment. Any such issuances of additional share capital may cause shareholders to experience significant dilution of their ownership interests and the per share value of our Class A ordinary shares to decline.

We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our Class A ordinary shares.

We do not intend to pay any cash dividends in the foreseeable future, and any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, you may need to rely on sales of our Class A ordinary shares after price appreciation, which may never occur, as the only way to realize any future gains on your investment.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting and disclosure requirements applicable to emerging growth companies will make our Class A ordinary shares less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act (“Section 404”), reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder

67

approval of any golden parachute payments not previously approved. Pursuant to Section 107 of the JOBS Act, as an emerging growth company, we have elected to use the extended transition period to enable us to comply with certain new or revised accounting standards.

We will remain an emerging growth company until the earliest of: (1) the last day of the fiscal year following the fifth anniversary of the closing of the Business Combination; (2) the last day of the first fiscal year in which our annual gross revenue is $1.07 billion or more; (3) the date on which we have, during the previous rolling three-year period, issued more than $1 billion in non-convertible debt securities; and (4) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates.

We cannot predict if investors will find our Class A ordinary shares less attractive if we choose to rely on these exemptions. If some investors find our Class A ordinary shares less attractive as a result, there may be a less active trading market for our Class A ordinary shares, and our share price may be more volatile.

We are a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company.

We report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (1) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (2) the sections of the Exchange Act requiring insiders to file public reports of their share ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (3) the rules under the Exchange Act requiring the filing with the U.S. Securities and Exchange Commission (the “SEC”) of quarterly reports on Form 10-Q containing unaudited financial and other specified information, although we are subject to Israeli laws and regulations with regard to certain of these matters and intend to furnish certain comparable quarterly information on Form 6-K. In addition, foreign private issuers are not required to file their annual report on Form 20-F until 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year and U.S. domestic issuers that are large accelerated filers are required to file their annual report on Form 10-K within 60 days after the end of each fiscal year. As a result of all of the above, you may not have the same protections afforded to shareholders of a company that is not a foreign private issuer.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses.

As discussed above, we are a foreign private issuer, and therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter, and, accordingly, the next determination will be made with respect to us on June 30, 2022. In the future, we would lose our foreign private issuer status if (1) more than 50% of our outstanding voting securities are owned by U.S. residents and (2) a majority of our directors or executive officers are U.S. citizens or residents, or we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. If we lose our foreign private issuer status, we will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms, which are more detailed and extensive than the forms available to a foreign private issuer. We will also have to mandatorily comply with U.S. federal proxy requirements,

68

and our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, we will lose our ability to rely upon exemptions from certain corporate governance requirements under the listing rules of the NYSE. As a U.S. listed public company that is not a foreign private issuer, we will incur significant additional legal, accounting and other expenses that we will not incur as a foreign private issuer.

As we are a “foreign private issuer” and intend to follow certain home country corporate governance practices, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all NYSE corporate governance requirements.

As a foreign private issuer, we have the option to follow certain home country corporate governance practices rather than those of NYSE, provided that we disclose the requirements we are not following and describe the home country practices we are following. We intend to rely on this “foreign private issuer exemption” with respect to NYSE rules for shareholder meeting quorums and shareholder approval requirements. We may in the future elect to follow home country practices with regard to other matters. As a result, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all NYSE corporate governance requirements.

We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to compliance with our public company responsibilities and corporate governance practices.

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company, which we expect to further increase after we are no longer an “emerging growth company.” The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the NYSE, and other applicable securities rules and regulations impose various requirements on public companies. Our management and other personnel are not experienced in managing a public company and will be required to devote a substantial amount of time to compliance with these requirements. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. We cannot predict or estimate the amount of additional costs we will incur as a public company or the specific timing of such costs.

As a result of being a public company, we are obligated to develop and maintain proper and effective internal controls over financial reporting, and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in our company and, as a result, the value of our Class A ordinary shares.

We will be required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting as of the end of the fiscal year that coincides with the filing of our second annual report on Form 20-F. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. In addition, our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting in our first annual report required to be filed with the SEC following the date we are no longer an “emerging growth company.”

Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. In addition, changes in accounting principles or interpretations could also challenge our internal controls and require that we establish new business processes, systems and controls to accommodate such changes. Additionally, if these new systems, controls or

69

standards and the associated process changes do not give rise to the benefits that we expect or do not operate as intended, it could materially and adversely affect our financial reporting systems and processes, our ability to produce timely and accurate financial reports or the effectiveness of internal control over financial reporting. Moreover, our business may be harmed if we experience problems with any new systems and controls that result in delays in their implementation or increased costs to correct any post-implementation issues that may arise.

During the evaluation and testing process of our internal controls, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to certify that our internal control over financial reporting is effective. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our Class A ordinary shares could decline, and we could be subject to sanctions or investigations by the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

The growth and expansion of our business places a continuous, significant strain on our operational and financial resources. Further growth of our operations to support our customer base, our platform, solutions and our internal controls and procedures may not be adequate to support our operations. As we continue to grow, we may not be able to successfully implement requisite improvements to these systems, controls and processes, such as system access and change. The growth and expansion of our business places a continuous, significant strain on our operational and financial resources. Further growth of our operations to support our customer base, our information technology systems and our internal controls and procedures may not be adequate to support our operations. As we continue to grow, we may not be able to successfully implement requisite improvements to these systems, controls and processes, such as system access and change management controls, in a timely or efficient manner. Our failure to improve our systems and processes, or their failure to operate in the intended manner, whether as a result of the growth of our business or otherwise, may result in our inability to accurately forecast our revenue and expenses, or to prevent certain losses. Moreover, the failure of our systems and processes could undermine our ability to provide accurate, timely and reliable reports on our financial and operating results and could impact the effectiveness of our internal control over financial reporting. In addition, our systems and processes may not prevent or detect all errors, omissions or fraud.

If a United States person is treated as owning at least 10% by vote or value of our shares, such holder may be subject to adverse U.S. federal income tax consequences.

Because our group consists of one or more U.S. subsidiaries, certain of our non-U.S. subsidiaries will be treated as “controlled foreign corporations,” (“CFCs”) as such term is defined in Section 957 of the Code, regardless of whether or not we are treated as a CFC. If a United States person (as defined in Section 7701(a)(30) of the Code) is treated as owning (directly, indirectly, or constructively) at least 10% of the total combined voting power of all classes of our shares entitled to vote or at least 10% of the total value of shares of all classes of our shares, such person may be treated as a “United States shareholder” with respect to each CFC in our group (if any), which may subject such person to adverse U.S. federal income tax consequences. Specifically, a United States shareholder of a CFC may be required to annually report and include in its U.S. taxable income its pro rata share of such CFC’s “Subpart F income,” “global intangible low-taxed income” and investments in U.S. property, whether or

70

not we make any distributions of profits or income of such CFC to such United States shareholder. If you are treated as a United States shareholder of a CFC, failure to comply with applicable reporting obligations may subject you to significant monetary penalties and may extend the statute of limitations with respect to such shareholder’s U.S. federal income tax return for the year for which reporting was due. Additionally a United States shareholder of a CFC that is an individual would generally be denied certain tax deductions or foreign tax credits in respect of its income that may otherwise be allowable to a United States shareholder that is a U.S. corporation. We cannot provide any assurances that we will assist holders of our shares in determining whether we or any of our non-U.S. subsidiaries are treated as CFCs or whether any holder of the Class A ordinary shares is treated as a United States shareholder with respect to any such CFC, nor do we expect to furnish to any United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations. The U.S. Internal Revenue Service has provided limited guidance regarding the circumstances in which investors may rely on publicly available information to comply with their reporting and taxpaying obligations with respect to CFCs. A United States investor should consult its advisors regarding the potential application of these rules to an investment in our Class A ordinary shares.

If we or any of our subsidiaries are characterized as a PFIC for U.S. federal income tax purposes, U.S. Holders may suffer adverse U.S. federal income tax consequences.

A non-U.S. corporation generally will be treated as a PFIC for U.S. federal income tax purposes, in 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 (generally 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. Based on the 2020 composition of the income, assets and operations of us and our subsidiaries, we do not believe we will be treated as a PFIC for the current taxable year, however there can be no assurances in this regard or any assurances that we will not be treated as a PFIC in any future taxable year. Moreover, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you that the IRS will not take a contrary position or that a court will not sustain such a challenge by the IRS.

Whether we or any of our subsidiaries are a PFIC for any taxable year is a factual determination that depends on, among other things, the composition of our income and assets, our market value and the market value of our subsidiaries’ shares and assets. Changes in our composition, the composition of our income or the composition of any of our subsidiaries assets may cause us to be or become a PFIC for the current or subsequent taxable years. Whether we are treated as a PFIC for U.S. federal income tax purposes is a factual determination that must be made annually at the close of each taxable year and, thus, is subject to significant uncertainty.

If we are a PFIC for any taxable year, a U.S. Holder of our ordinary shares may be subject to adverse tax consequences and may incur certain information reporting obligations. For a further discussion, see “Certain Material U.S. Federal Income Tax Considerations—U.S. Holders—Passive Foreign Investment Company Rules.” U.S. Holders of our ordinary shares are strongly encouraged to consult their own advisors regarding the potential application of these rules to us and the ownership of our ordinary shares.

RISKS RELATED TO OUR INCORPORATION AND LOCATION IN ISRAEL

Conditions in Israel could materially and adversely affect our business.

Many of our employees, including our founders and certain members of our management team, operate from our headquarters that is located in Tel Aviv, Israel. In addition, a number of our officers and directors are residents of Israel. Accordingly, political, economic and military conditions in Israel

71

and the surrounding region may directly affect our business and operations. Recently, there has been an unprecedented degree of political instability in Israel, with four sets of elections for the Israeli parliament, or Knesset, in a two-year period. While a new government was formed in June 2021, there is no guarantee that it will last for a significant portion of its full four-year term and provide political stability. On the military front, in recent years, Israel has been engaged in sporadic armed conflicts with Hamas, an Islamist terrorist group that controls the Gaza Strip, with Hezbollah, an Islamist terrorist group that controls large portions of southern Lebanon, and with Iranian-backed military forces in Syria. In addition, Iran has threatened to attack Israel and may be developing nuclear weapons. Some of these hostilities were accompanied by missiles being fired from the Gaza Strip, Lebanon and Syria against civilian targets in various parts of Israel, including areas in which our employees are located, which negatively affected business conditions in Israel. Any hostilities involving Israel, regional political instability or the interruption or curtailment of trade between Israel and its trading partners could materially and adversely affect our operations and results of operations.

Our commercial insurance does not cover losses that may occur as a result of events associated with war and terrorism. Although the Israeli government currently covers the reinstatement value of property damage and certain direct and indirect damages that are caused by terrorist attacks or acts of war, such coverage would likely be limited, may not be applicable to our business (either due to the geographic location of our offices or the type of business that we operate) and may not reinstate our loss of revenue or economic losses more generally. Furthermore, we cannot assure you that this government coverage will be maintained or that it will sufficiently cover our potential damages. Any losses or damages incurred by us could have a material adverse effect on our business, financial condition and results of operations.

Further, in the past, the State of Israel and Israeli companies have been subjected to economic boycotts. Several countries still restrict business with the State of Israel and with Israeli companies. These restrictive laws and policies may have an adverse impact on the expansion of our business, financial condition and/or our results of operations. In addition, a campaign of boycotts, divestment and sanctions has been undertaken against Israel, which could also materially and adversely impact our business.

In addition, many Israeli citizens are obligated to perform several days, and in some cases more, of annual military reserve duty each year until they reach the age of 40 (or older, for reservists who are military officers or who have certain occupations) and, in the event of a military conflict, may be called to active duty. In response to increases in terrorist activity, there have been periods of significant call-ups of military reservists. It is possible that there will be military reserve duty call-ups in the future. Our operations could be disrupted by such call-ups, particularly if such call-ups include the call-up of members of our management. Such disruption could materially and adversely affect our business, financial condition and results of operations.

The tax benefits that are available to us require us to continue to meet various conditions and may be terminated or reduced in the future, which could increase our costs and taxes.

We believe that we are eligible for certain tax benefits provided to a “Preferred Technological Enterprise” under the Israeli Law for the Encouragement of Capital Investments, 5719-1959 (the “Investment Law”). In order to remain eligible for the tax benefits provided to a “Preferred Technological Enterprise” we must continue to meet certain conditions stipulated in the Investment Law and its regulations, as amended. If these tax benefits are reduced, cancelled or discontinued, our Israeli taxable income from the Preferred Technological Enterprise would be subject to regular Israeli corporate tax rates. The standard corporate tax rate for Israeli companies has been 23% since 2018. Additionally, if we increase our activities outside of Israel through acquisitions, for example, our expanded activities might not be eligible for inclusion in future Israeli tax benefit programs. See “Taxation and Government Programs—Israeli Tax Considerations.”

72

Our amended and restated articles of association contain a forum selection clause for substantially all disputes between us and our shareholders under the Companies Law and the Israeli Securities Law, which could limit our shareholders’ ability to bring claims and proceedings against us, our directors, officers and other employees. Enforcement of a U.S. judgment against us or our officers and directors in Israel or the United States, or assertion of a U.S. securities laws claim in Israel or serving process on our officers and directors, may also be difficult.

Under our amended and restated articles of association, the competent courts of Tel Aviv, Israel are the exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company’s shareholders, or (iii) any action asserting a claim arising pursuant to any provision of the Israeli Companies Law, 5759-1999 (the “Companies Law”), or the Israeli Securities Law, 1968 (the “Israeli Securities Law”). This exclusive forum provision is intended to apply to claims arising under Israeli law and would not apply to claims brought pursuant to the Securities Act or the Exchange Act or any other claim for which federal courts would have exclusive jurisdiction. Such exclusive forum provision in our amended and restated articles of association will not relieve us of our duties to comply with federal securities laws and the rules and regulations thereunder, and our shareholders will not be deemed to have waived our compliance with these laws, rules and regulations. This exclusive forum provision may limit a shareholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us, our directors, officers and employees.

Another obstacle towards assertion of claims against us or our directors or officers is the fact that most of them are not residents of the United States and most of their and our assets are located outside the United States. Service of process upon us or our non-U.S. resident directors and officers and enforcement of judgments obtained in the United States against us or our non-U.S. directors and executive officers may therefore be difficult to effect within the United States. We have been informed by our legal counsel in Israel that it may be difficult to assert claims under U.S. securities laws in original actions instituted in Israel or obtain a judgment based on the civil liability provisions of U.S. federal securities laws. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws against us or our non-U.S. officers and directors because Israel may not be the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proven as a fact, which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing these matters.

Additionally, Israeli courts might not enforce judgments obtained in the United States against us or our non-U.S. directors and executive officers, which may make it difficult to collect on judgments rendered against us or our non-U.S. officers and directors. An Israeli court will not enforce a non-Israeli judgment if it was given in a state whose laws do not provide for the enforcement of judgments of Israeli courts (subject to exceptional cases), if its enforcement is likely to prejudice the sovereignty or security of the State of Israel, if it was obtained by fraud or in the absence of due process, if it is at variance with another valid judgment that was given in the same matter between the same parties, or if a suit in the same matter between the same parties was pending before a court or tribunal in Israel at the time the foreign action was brought. For more information, see “Enforceability of Civil Liabilities.”

73

Your rights and responsibilities as our shareholder will be governed by Israeli law, which may differ in some respects from the rights and responsibilities of shareholders of U.S. corporations.

We are incorporated under Israeli law. The rights and responsibilities of holders of our Class A and Class B ordinary shares are governed by our amended and restated articles of association and the Companies Law. These rights and responsibilities differ in some respects from the rights and responsibilities of shareholders in typical U.S. corporations. In particular, pursuant to the Companies Law each shareholder of an Israeli company has to act in good faith and in a customary manner in exercising his, her or its rights and fulfilling his, her or its obligations toward the Company and other shareholders and to refrain from abusing his, her or its power in the Company, including, among other things, in voting at the general meeting of shareholders on amendments to a company’s articles of association, increases in a company’s authorized share capital, mergers and certain transactions requiring shareholders’ approval under the Companies Law. In addition, a controlling shareholder of an Israeli company or a shareholder who knows that it possesses the power to determine the outcome of a shareholder vote or who has the power to appoint or prevent the appointment of a director or officer in the Company or has other powers toward the Company has a duty of fairness toward the Company. However, Israeli law does not define the substance of this duty of fairness. There is little case law available to assist in understanding the implications of these provisions that govern shareholder behavior.

Provisions of Israeli law and our amended and restated articles of association may delay, prevent or make undesirable an acquisition of all or a significant portion of our shares or assets.

Provisions of Israeli law and our amended and restated articles of association could have the effect of delaying or preventing a change in control and may make it more difficult for a third-party to acquire us or our shareholders to elect different individuals to our board of directors, even if doing so would be considered to be beneficial by some of our shareholders, and may limit the price that investors may be willing to pay in the future for our Class A ordinary shares. Among other things:

74

Further, Israeli tax considerations may make potential transactions undesirable to us or to some of our shareholders whose country of residence does not have a tax treaty with Israel granting tax relief to such shareholders from Israeli tax. For example, Israeli tax law does not recognize tax-free share exchanges to the same extent as U.S. tax law. With respect to mergers, Israeli tax law allows for tax deferral in certain circumstances but makes the deferral contingent on the fulfillment of numerous conditions, including a restrictive period of two years from the date of the transaction during which certain sales and dispositions of shares of the participating companies are restricted. Moreover, with respect to certain share swap transactions, the tax deferral is limited in time, and when such time expires, the tax becomes payable even if the shares have not been disposed.

75

DIVIDEND POLICY

We do not anticipate paying any dividends in the foreseeable future. We currently intend to retain future earnings, if any, to finance operations and expand our business. Our board of directors has sole discretion whether to pay dividends. If our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that our directors may deem relevant.

For the year ended December 31, 2020, we did not pay any dividends. For the years ended December 31, 2019 and 2018, we paid dividends of $100 million and $135 million, respectively.

The Companies Law imposes restrictions on our ability to declare and pay dividends. See “Description of Share Capital and Articles of Association—Dividend and Liquidation Rights” for additional information. Our ability to pay dividends is also restricted by the terms of our credit agreement, as described further in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Agreement,” and may be restricted by any agreements we may enter into in the future. See also “Risk Factors—Risks Related to Our Class A Ordinary Shares—We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our Class A ordinary shares.”

Payment of dividends may be subject to Israeli withholding taxes. See “Taxation and Government Programs—Israeli Tax Considerations” for additional information.

Note 1—Description of the Business Combination

On June 28, 2021 (the “Closing Date”), we consummated the previously announced business combination (the “Business Combination”) pursuant to the Agreement and Plan of Merger, dated March 20, 2021, by and among the Company, Thoma Bravo Advantage, a Cayman Islands exempted company (“TBA”), Showtime Cayman, a wholly-owned subsidiary of the Company (“Merger Sub”), and Showtime Cayman II, a Cayman Islands exempted company and wholly-owned subsidiary of the Company (“Merger Sub II”) (the “Business Combination”).

On the Closing Date, the following transactions occurred pursuant to the terms of the Merger Agreement:

Our Class A ordinary shares began trading on The New York Stock Exchange on June 29, 2021 under the symbol “IS.”

87

PIPE Investment

On March 20, 2021, we entered into Investment Agreements (each, an “Investment Agreement”) with certain investors (each, a “PIPE Investor” and collectively, the “PIPE Investors”) pursuant to which, among other things, the PIPE Investors agreed to purchase on the Closing Date an aggregate of 130 million ironSource Class A ordinary shares at a price equal to $10.00 per share on the terms and subject to the conditions set forth therein for gross proceeds of $1.3 billion (the “PIPE Financing”). In accordance with the Support Agreement, as a result of redemptions by stockholders of TBA, the Sponsor entered into a similar Investment Agreement with respect to an amount of approximately $32.5 million. The PIPE Financing closed concurrently with the Business Combination. On the Closing Date the existing shareholders of ironSource effected a secondary sale of 140 million ironSource Class A ordinary shares and/or ironSource Class B ordinary shares to the PIPE Investors (including the Sponsor), for a total purchase price of $1.4 billion, and including a secondary sale in an amount of approximately $67.5 million to TBA, which was funded from TBA’s trust account. Under our Amended and Restated Articles of Association, each share sold on a secondary basis was a Class A ordinary share upon purchase by a PIPE Investor.

Consideration

The following represents the aggregate merger consideration (excluding any secondary acquisition of shares):

The following summarizes the unaudited pro forma ordinary shares outstanding, after giving effect to the transactions that occurred on the Closing Date:

The above share amounts and ownership percentages have been calculated based on the following assumptions:

Each of the share amounts and ownership percentages reflected in the above table has furthermore been calculated based on certain additional assumptions, which are described below in “Note 2. Basis of Presentation.”

Note 2—Basis of Presentation

The following unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2021 and the year ended December 31, 2020 are based on the historical financial statements of ironSource and TBA.

The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X, Pro Forma Financial Information, as amended by the final rule, Amendments to Financial Disclosures about Acquired and Disposed Businesses, as adopted by the SEC in May 2020 (“Article 11”). The amended Article 11 is effective on January 1, 2021. The unaudited pro forma adjustments are based on information currently available, and assumptions and estimates underlying the unaudited pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions used to present the accompanying unaudited pro forma condensed combined financial information.

ironSource and TBA did not have any historical relationship prior to the Transaction. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2021 and the year ended December 31, 2020, presents pro forma effect to the Business Combination and related transactions as if they had been completed on January 1, 2020, the beginning of the earliest period presented.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these estimates, the final amounts recorded may differ materially from the information presented.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination and related transactions.

The pro forma adjustments reflecting the consummation of the Business Combination are based on certain currently available information and certain assumptions and methodologies that ironSource believes are reasonable under the circumstances. ironSource believes that these assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at the time and that the pro forma

adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the Business Combination taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the combined company.

Note 3—Accounting Policies

Upon consummation of the recapitalization, management performed a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the Post-Combination Company. Based on its analysis, management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.
