Risks Related to Our Business and Our Industry

Our business depends on our ability to attract new customers and hosts, retain and upsell additional products to existing customers and upgrade free hosts to our paid offerings. Any decline in new customers and hosts, renewals or upgrades would harm our business.

Our business depends upon our ability to attract new customers and hosts and maintain and expand our relationships with our customers and hosts, including upselling additional products to our existing customers and upgrading hosts to a paid Zoom Meeting plan. A host is any user of our video-first communications platform who initiates a Zoom Meeting and invites one or more participants to join that meeting. We refer to hosts who subscribe to a paid Zoom Meeting plan as “paid hosts.” We define a customer as a separate and distinct buying entity, which can be a single paid host or an organization of any size (including a distinct unit of an organization) that has multiple paid hosts.

Our business is subscription based, and customers are not obligated to and may not renew their subscriptions after their existing subscriptions expire. As a result, we cannot provide assurance that customers will renew their subscriptions utilizing the same tier of their Zoom Meeting plan, upgrade to a higher-priced tier or purchase additional products, if they renew at all. Renewals of subscriptions to our platform may decline or fluctuate because of several factors, such as dissatisfaction with our products and support, a customer or host no longer having a need for our products, or the perception that competitive products provide better or less expensive options. In addition, some customers downgrade their Zoom Meeting plan or do not renew their subscriptions. We must continually add new customers and hosts to grow our business beyond our current user base and to replace customers and hosts who choose not to continue to use our platform. Any decrease in user satisfaction with our products or support would harm our brand, word-of-mouth referrals and ability to grow.

We encourage customers to purchase additional products and encourage hosts to upgrade to our paid offerings by recommending additional features and through in-product prompts and notifications. Additionally, we seek to expand within organizations by adding new hosts, having workplaces purchase additional products, or expanding the use of Zoom into other teams and departments within an organization. At the same time, we strive to demonstrate the value of our platform and various product offerings to those hosts that subscribe to our free Zoom Meeting plan, thereby encouraging them to upgrade to a paid Zoom Meeting plan. However, a majority of these hosts may never upgrade to a paid Zoom Meeting plan. If we fail to upsell our customers or upgrade hosts of our free Zoom Meeting plan to a paid subscription or expand the number of paid hosts within organizations, our business would be harmed.

In addition, our user growth rate may slow in the future as our market penetration rates increase and we turn our focus to upgrading our free hosts to a paid Zoom Meeting plan rather than growing the total number of users. If we are not able to continue to expand our user base or fail to upgrade our free hosts to a paid Zoom Meeting plan, our revenue may grow more slowly than expected or decline.

13

We have a limited operating history, which makes it difficult to evaluate our prospects and future results of operations.

We were incorporated in 2011. As a result of our limited operating history, our ability to forecast our future results of operations is limited and subject to a number of uncertainties, including our ability to plan for and model future growth. Our historical revenue growth should not be considered indicative of our future performance. Further, in future periods, our revenue growth could slow or our revenue could decline for a number of reasons, including any reduction in demand for our platform, increased competition, contraction of our overall market, our inability to accurately forecast demand for our platform and plan for capacity constraints or our failure, for any reason, to capitalize on growth opportunities. We have encountered and will encounter risks and uncertainties frequently experienced by growing companies in rapidly changing industries, such as the risks and uncertainties described herein. If our assumptions regarding these risks and uncertainties, which we use to plan our business, are incorrect or change, or if we do not address these risks successfully, our business would be harmed.

We operate in competitive markets, and we must continue to compete effectively.

The market for communication and collaboration technologies platforms is competitive and rapidly changing. Certain features of our current platform compete in the communication and collaboration technologies market with products offered by:

Other large established companies like Amazon and Facebook have in the past and may in the future also make investments in video communications tools. In addition, as we introduce new products and services, and with the introduction of new technologies and market entrants, we expect competition to intensify in the future. For example, we recently introduced Zoom Phone, a cloud phone system that will allow customers to replace their existing private branch exchange solution, in the future, which will result in increased competition against companies that offer similar services and new competitors that may enter that market in the future. Further, many of our actual and potential competitors benefit from competitive advantages over us, such as greater name recognition, longer operating histories, more varied products and services, larger marketing budgets, more established marketing relationships, third-party integration, greater accessibility across devices or applications, access to larger user bases, major distribution agreements with hardware manufacturers and resellers, and greater financial, technical and other resources. Some of our competitors may make acquisitions or enter into strategic relationships to offer a broader range of products and services than we do. These combinations may make it more difficult for us to compete effectively. We expect these trends to continue as competitors attempt to strengthen or maintain their market positions.

Demand for our platform is also price sensitive. Many factors, including our marketing, user acquisition and technology costs, and our current and future competitors’ pricing and marketing strategies, can significantly affect our pricing strategies. Certain competitors offer, or may in the future offer, lower-priced or free products or services that compete with our platform or may bundle and offer a broader range of products and services. Similarly, certain competitors may use marketing strategies that enable them to acquire customers at a lower cost than we can. Furthermore, third parties could build products similar to ours that rely on open source software. Even if such products do not include all the features and functionality that our platform provides, we could face pricing pressure from these third parties to the extent that users find such alternative products to be sufficient to meet their video communications needs. There can be no assurance that we will not be forced to engage in price-cutting initiatives or other discounts or to increase our marketing and other expenses to attract and retain customers in response to competitive pressures, either of which would harm our business.

14

We may not be able to sustain our revenue growth rate in the future.

We have experienced significant revenue growth in prior periods. You should not rely on the revenue growth of any prior quarterly or annual period as an indication of our future performance. We expect our revenue growth rate to decline in future periods. Many factors may contribute to declines in our growth rate, including higher market penetration, increased competition, slowing demand for our platform, a failure by us to continue capitalizing on growth opportunities and the maturation of our business, among others. If our growth rate declines, investors’ perceptions of our business and the trading price of our Class A common stock could be adversely affected.

Interruptions, delays or outages in service from our co-located data centers and a variety of other factors would impair the delivery of our services, require us to issue credits or pay penalties and harm our business.

We currently serve our users from 13 co-located data centers in Australia, Brazil, Canada, China, Germany, India, Japan, the Netherlands and the United States. We also utilize Amazon Web Services and Microsoft Azure for the hosting of certain critical aspects of our business. As part of our distributed meeting architecture, we establish private links between data centers that automatically transfer data between various data centers in order to optimize performance on our platform. Damage to, or failure of, these data centers has in the past resulted in and could in the future result in interruptions or delays in our services. In addition, we have experienced, and may in the future experience, other interruptions and delays in our services caused by a variety of other factors, including but not limited to infrastructure changes, vendor issues, human or software errors, viruses, security attacks, fraud, general internet availability issues, spikes in usage and denial of service issues. In some instances, we may not be able to identify the cause or causes of these performance problems within an acceptable period of time. For example, in January 2019, we experienced an outage in our services for less than two hours, which we later determined was initially caused by a technical issue with one of our vendors. Additionally, in connection with the addition of new data centers or expansion or consolidation of our existing data center facilities or other reasons, we may move or transfer our data and our users’ metadata to other data centers. Despite precautions that we take during this process, any unsuccessful data transfers may impair or cause disruptions in the delivery of our service, and we may incur significant costs in connection with any such move or transfer. Interruptions, delays or outages in our services would reduce our revenue, may require us to issue credits or pay penalties, may subject us to claims and litigation, may cause customers and hosts to terminate their subscriptions and adversely affect our ability to attract new customers and hosts. Our ability to attract and retain customers and hosts depends on our ability to provide customers and hosts with a highly reliable platform and even minor interruptions or delays in our services could harm our business.

Additionally, if our data centers are unable to keep up with our increasing needs for capacity, customers may experience delays as we seek to obtain additional capacity, which could harm our business.

We do not control, or in some cases have limited control over, the operation of the co-located data center facilities we use, and they are vulnerable to damage or interruption from human error, intentional bad acts, earthquakes, floods, fires, hurricanes, war, terrorist attacks, power losses, hardware failures, systems failures, telecommunications failures and similar events, any of which could disrupt our service. In the event of significant physical damage to one of these data centers, it may take a significant period of time to achieve full resumption of our services, and our disaster recovery planning may not account for all eventualities. Despite precautions taken at these facilities, the occurrence of a natural disaster, an act of terrorism or other act of malfeasance, a decision to close the facilities without adequate notice or other unanticipated problems at the facilities would harm our business.

Failures in internet infrastructure or interference with broadband access could cause current or potential users to believe that our systems are unreliable, possibly leading our customers and hosts to switch to our competitors or to cancel their subscriptions to our platform.

Unlike traditional communications and collaborations technologies, our services depend on our users’ high-speed broadband access to the internet, usually provided through a cable or digital subscriber line connection.

15

Increasing numbers of users and increasing bandwidth requirements may degrade the performance of our platform due to capacity constraints and other internet infrastructure limitations. As our number of users grows and their usage of communications capacity increases, we will be required to make additional investments in network capacity to maintain adequate data transmission speeds, the availability of which may be limited, or the cost of which may be on terms unacceptable to us. If adequate capacity is not available to us as our user base grows, our network may be unable to achieve or maintain sufficiently high data transmission capacity, reliability or performance. In addition, if internet service providers and other third parties providing internet services have outages or deteriorations in their quality of service, our users will not have access to our platform or may experience a decrease in the quality of our platform. Furthermore, as the rate of adoption of new technologies increases, the networks our platform relies on may not be able to sufficiently adapt to the increased demand for these services, including ours. Frequent or persistent interruptions could cause current or potential users to believe that our systems or platform are unreliable, leading them to switch to our competitors or to avoid our platform, and could permanently harm our business.

In addition, users who access our platform through mobile devices, such as smartphones and tablets, must have a high-speed connection, such as 3G, 4G or LTE, satellite or Wi-Fi to use our services and applications. Currently, this access is provided by companies that have significant and increasing market power in the broadband and internet access marketplace, including incumbent phone companies, cable companies, satellite companies and wireless companies. Some of these providers offer products and subscriptions that directly compete with our own offerings, which can potentially give them a competitive advantage. Also, these providers could take measures that degrade, disrupt or increase the cost of user access to third-party services, including our platform, by restricting or prohibiting the use of their infrastructure to support or facilitate third-party services or by charging increased fees to third parties or the users of third-party services, any of which would make our platform less attractive to users and reduce our revenue.

On January 4, 2018, the Federal Communications Commission (FCC) released an order reclassifying broadband internet access as an information service, subject to certain provisions of Title I of the Communications Act. The order requires broadband providers to publicly disclose accurate information regarding network management practices, performance characteristics and commercial terms of their broadband internet access services sufficient to enable consumers to make informed choices regarding the purchase and use of such services and entrepreneurs and other small businesses to develop, market and maintain internet offerings. The new rules went into effect on June 11, 2018 and are the subject of various appeals and congressional review. Moreover, a number of states are adopting or considering legislation or executive actions that would regulate the conduct of broadband providers. We cannot predict whether the FCC order or state initiatives will be modified, overturned, or vacated by legal action of the court, federal legislation, or the FCC. Under the new rules, broadband internet access providers may be able to charge web-based services such as ours for priority access, which could result in increased costs and a loss of existing customers and hosts, impair our ability to attract new customers and hosts, and harm our business.

As we increase sales to large organizations, our sales cycles could lengthen, and we could experience greater deployment challenges.

As our business evolves, we may need to invest more resources into sales to large organizations. Large organizations typically undertake a significant evaluation and negotiation process due to their leverage, size, organizational structure and approval requirements, all of which can lengthen our sales cycle. We may also face unexpected deployment challenges with large organizations or more complicated deployment of our platform. Large organizations may demand additional features, support services and pricing concessions or require additional security management or control features. We may spend substantial time, effort and money on sales efforts to large organizations without any assurance that our efforts will produce any sales or that these customers will deploy our platform widely enough across their organization to justify our substantial upfront investment. As a result, we anticipate increased sales to large organizations will lead to higher upfront sales costs and greater unpredictability in our business, results of operations and financial condition.

16

We generate revenue from sales of subscriptions to our platform, and any decline in demand for our platform or for communications and collaboration technologies in general would harm our business.

We generate, and expect to continue to generate, revenue from the sale of subscriptions to our platform. As a result, widespread acceptance and use of communications and collaboration technologies in general, and our platform in particular, is critical to our future growth and success. If the communications and collaboration technologies market fails to grow or grows more slowly than we currently anticipate, demand for our platform could be negatively affected.

Changes in user preferences for communications and collaboration technologies may have a disproportionately greater impact on us than if we offered multiple platforms or disparate products. Demand for communications and collaboration technologies in general, and our platform in particular, is affected by a number of factors, many of which are beyond our control. Some of these potential factors include:

The communications and collaboration technologies market is subject to rapidly changing user demand and trends in preferences. If we fail to successfully predict and address these changes and trends, meet user demands or achieve more widespread market acceptance of our platform, our business would be harmed.

The experience of our users depends upon the interoperability of our platform across devices, operating systems and third-party applications that we do not control, and if we are not able to maintain and expand our relationships with third parties to integrate our platform with their solutions, our business may be harmed.

One of the most important features of our platform is its broad interoperability with a range of diverse devices, operating systems and third-party applications. Our platform is accessible from the web and from devices running Windows, Mac OS, iOS, Android and Linux. We also have integrations with Atlassian, Dropbox, Google, LinkedIn, Microsoft, Salesforce, Slack and a variety of other productivity, collaboration, data management and security vendors. We are dependent on the accessibility of our platform across these and other third-party operating systems and applications that we do not control. For example, given the broad adoption of Microsoft Office and other productivity software, it is important that we are able to integrate with this software. Several of our competitors own, develop, operate, or distribute operating systems, app stores, co-located data center services and other software, and also have material business relationships with companies that own, develop, operate or distribute operating systems, applications markets, co-located data center services and other software that our platform requires in order to operate. Moreover, some of these competitors have inherent advantages developing products and services that more tightly integrate with their software and hardware platforms or those of their business partners.

17

Third-party services and products are constantly evolving, and we may not be able to modify our platform to assure its compatibility with that of other third parties following development changes. In addition, some of our competitors may be able to disrupt the operations or compatibility of our platform with their products or services, or exert strong business influence on our ability to, and terms on which we, operate and distribute our platform. For example, we currently offer products that directly compete with several large technology companies that we rely on to ensure the interoperability of our platform with their products or services. As our respective products evolve, we expect this level of competition to increase. Should any of our competitors modify their products or standards in a manner that degrades the functionality of our platform or gives preferential treatment to competitive products or services, whether to enhance their competitive position or for any other reason, the interoperability of our platform with these products could decrease and our business could be harmed.

In addition, we provide, develop and create applications for our platform partners that integrate our platform with our partners’ various offerings. For example, our Zoom Meetings product integrates with tools offered by companies such as Atlassian and Dropbox to help teams get more done together. If we are not able to continue and expand on existing and new relationships to integrate our platform with our partners’ solutions, or there are quality issues with our products or service interruptions of our products that integrate with our partners’ solutions, our business will be harmed.

We may not be able to respond to rapid technological changes, extend our platform or develop new features.

The communications and collaboration technologies market is characterized by rapid technological change and frequent new product and service introductions. Our ability to grow our user base and increase revenue from customers will depend heavily on our ability to enhance and improve our platform, introduce new features and products and interoperate across an increasing range of devices, operating systems and third-party applications. Our customers may require features and capabilities that our current platform does not have. We invest significantly in research and development, and our goal is to focus our spending on measures that improve quality and ease of adoption and create organic user demand for our platform. There is no assurance that our enhancements to our platform or our new product experiences, features or capabilities will be compelling to our users or gain market acceptance. If our research and development investments do not accurately anticipate user demand, or if we fail to develop our platform in a manner that satisfies user preferences in a timely and cost-effective manner, we may fail to retain our existing users or increase demand for our platform.

The introduction of new products and services by competitors or the development of entirely new technologies to replace existing offerings could make our platform obsolete or adversely affect our business, results of operations and financial condition. We may experience difficulties with software development, design or marketing that could delay or prevent our development, introduction, or implementation of new product experiences, features, or capabilities. We have in the past experienced delays in our internally planned release dates of new features and capabilities, and there can be no assurance that new product experiences, features or capabilities will be released according to schedule. Any delays could result in adverse publicity, loss of revenue or market acceptance, or claims by users brought against us, all of which could harm our business. Moreover, new productivity features to our platform may require substantial investment, and we have no assurance that such investments will be successful. If customers and hosts do not widely adopt our new product experiences, features and capabilities, we may not be able to realize a return on our investment. If we are unable to develop, license or acquire new features and capabilities to our platform on a timely and cost-effective basis, or if such enhancements do not achieve market acceptance, our business would be harmed.

The failure to effectively develop and expand our marketing and sales capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our platform.

Our ability to increase our customer and host base and achieve broader market acceptance of our products and services will depend to a significant extent on our ability to expand our marketing and sales operations. We plan to continue expanding our sales force and strategic partners, both domestically and internationally.

18

Identifying and recruiting qualified sales representatives and training them is time-consuming and resource-intensive, and they may not be fully trained and productive for a significant amount of time. We also plan to dedicate significant resources to sales and marketing programs, including internet and other online advertising. Further, we are currently recruiting a new Head of Worldwide Sales or role with similar responsibility, which will require significant management time and resources. All of these efforts will require us to invest significant financial and other resources. In addition, the cost to acquire customers and hosts is high due to these marketing and sales efforts. Our business will be harmed if our efforts do not generate a correspondingly significant increase in revenue. We will not achieve anticipated revenue growth from expanding our sales force if we are unable to hire, develop and retain talented sales personnel, if our new sales personnel are unable to achieve desired productivity levels in a reasonable period of time or if our sales and marketing programs are not effective.

Our security measures have on occasion, in the past, been, and may in the future be, compromised. Consequently, our products and services may be perceived as not being secure. This perception may result in customers and hosts curtailing or ceasing their use of our products, our incurring significant liabilities and our business being harmed.

Our operations involve the storage and transmission of customer data or information, and security incidents have occurred in the past, and may occur in the future, resulting in unauthorized access to, loss of or unauthorized disclosure of this information, regulatory enforcement actions, litigation, indemnity obligations and other possible liabilities, as well as negative publicity, which could damage our reputation, impair our sales and harm our business. Cyberattacks and other malicious internet-based activity continue to increase, and cloud-based platform providers of products and services have been and are expected to continue to be targeted. In addition to traditional computer “hackers,” malicious code (such as viruses and worms), employee theft or misuse and denial-of-service attacks, sophisticated nation-state and nation-state supported actors now engage in attacks (including advanced persistent threat intrusions). Despite significant efforts to create security barriers to such threats, it is virtually impossible for us to entirely mitigate these risks. If our security measures are compromised as a result of third-party action, employee, customer, host or user error, malfeasance, stolen or fraudulently-obtained log-in credentials or otherwise, our reputation would be damaged, our data, information or intellectual property, or those of our customers, may be destroyed, stolen or otherwise compromised, our business may be harmed and we could incur significant liability. We have not always been able in the past and may be unable in the future to anticipate or prevent techniques used to obtain unauthorized access or to compromise our systems because they change frequently and are generally not detected until after an incident has occurred. For example, in July 2018 we were made aware of a vulnerability in the Zoom Meeting client for Windows that could result in potential exposure of a Zoom user’s password. Additionally, in 2018, a cybersecurity company discovered a vulnerability in our software that could be exploited by hackers to exert certain meeting controls. While we were able to deploy updates to the software addressing these vulnerabilities and we are not aware of any customers being affected or meetings compromised by these vulnerabilities, customers are responsible for installing this update to the software and their software is subject to these vulnerabilities until they do so. Additionally, we cannot be certain that we will be able to address any vulnerabilities in our software that we may become aware of in the future. We expect similar issues to arise in the future as we continue to expand the features and functionality of existing products and introduce new products, and we expect to expend significant resources in an effort to protect against security incidents. Concerns regarding privacy, data protection and information security may cause some of our customers and hosts to stop using our solutions and fail to renew their subscriptions. This discontinuance in use or failure to renew could substantially harm our business. Further, as we rely on third-party and public-cloud infrastructure, we depend in part on third-party security measures to protect against unauthorized access, cyberattacks and the mishandling of data and information. In addition, failures to meet customers’ and hosts’ expectations with respect to security and confidentiality of their data and information could damage our reputation and affect our ability to retain customers and hosts, attract new customers and hosts and grow our business. In addition, a cybersecurity event could result in significant increases in costs, including costs for remediating the effects of such an event, lost revenue due to network downtime, and a decrease in customer, host and user trust, increases in insurance

19

premiums due to cybersecurity incidents, increased costs to address cybersecurity issues and attempts to prevent future incidents, and harm to our business and our reputation because of any such incident.

Many governments have enacted laws requiring companies to provide notice of data security incidents involving certain types of personal data. In addition, some of our customers require us to notify them of data security breaches. Security compromises experienced by our competitors, by our customers or by us may lead to public disclosures, which may lead to widespread negative publicity. In addition, we have a high concentration of research and development personnel in China, which could expose us to market scrutiny regarding the integrity of our solution or data security features. Any security compromise in our industry, whether actual or perceived, could harm our reputation, erode confidence in the effectiveness of our security measures, negatively affect our ability to attract new customers and hosts, cause existing customers to elect not to renew their subscriptions or subject us to third-party lawsuits, regulatory fines or other action or liability, which could harm our business.

There can be no assurance that any limitations of liability provisions in our subscription agreements would be enforceable or adequate or would otherwise protect us from any such liabilities or damages with respect to any particular claim. We also cannot be sure that our existing general liability insurance coverage and coverage for cyber liability or errors or omissions will continue to be available on acceptable terms or will be available in sufficient amounts to cover one or more large claims or that the 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, would harm our business.

Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of users will be impaired and our business will be harmed.

We believe that our brand identity and awareness have contributed to our success and have helped fuel our efficient go-to-market strategy. We connect people through frictionless video, voice, chat and content sharing. We also believe that maintaining and enhancing the Zoom brand is critical to expanding our base of customers, hosts and users and, in particular, conveying to users and the public that the Zoom brand consists of a broad communications platform, rather than just one distinct product. For example, if users incorrectly view the Zoom brand primarily as a video conferencing point solution or utility rather than as a platform with multiple communications solutions, then our market position may be detrimentally impacted at such time as a competitor introduces a new or better product. We anticipate that, as our market becomes increasingly competitive, maintaining and enhancing our brand may become increasingly difficult and expensive. Any unfavorable publicity or perception of our platform or the providers of communication and collaboration technologies generally could adversely affect our reputation and our ability to attract and retain hosts. If we fail to promote and maintain the Zoom brand, including consumer and public perception of our platform, or if we incur excessive expenses in this effort, our business will be harmed.

We have a history of net losses, and we expect to increase our expenses in the future, which could prevent us from achieving or maintaining profitability.

Although we generated net income of $7.6 million for the fiscal year ended January 31, 2019, we have incurred net losses in the past, including a net loss of $3.8 million for the fiscal year ended January 31, 2018, and could incur net losses in the future. We intend to continue to expend significant funds to expand our direct sales force and marketing efforts to attract new customers and hosts, to develop and enhance our products and for general corporate purposes, including operations, hiring additional personnel, upgrading our infrastructure and expanding into new geographical markets. To the extent we are successful in increasing our user base, we may also incur increased losses because, other than sales commissions, the costs associated with acquiring customers and hosts are generally incurred up front, while the subscription revenue is generally recognized ratably over the subscription term, which can be monthly, annual or on a multi-year basis. Our efforts to grow our business may be costlier than we expect, and we may not be able to increase our revenue enough to offset our higher operating

20

expenses. We may incur significant losses in the future for a number of reasons, including as a result of the other risks described herein, and unforeseen expenses, difficulties, complications, delays and other unknown events. If we are unable to achieve and sustain profitability, the value of our business and Class A common stock may significantly decrease. Furthermore, it is difficult to predict the size and growth rate of our market, customer demand for our platform, user adoption and renewal of our platform, the entry of competitive products and services, or the success of existing competitive products and services. As a result, we may not achieve or maintain profitability in future periods. If we fail to grow our revenue sufficiently to keep pace with our investments and other expenses, our business would be harmed.

We may not successfully manage our growth or plan for future growth.

Since our founding in 2011, we have experienced rapid growth. For example, our headcount has grown to 1,702 full-time employees as of January 31, 2019, with employees located both in the United States and internationally. The growth and expansion of our business places a continuous, significant strain on our management, operational and financial resources. Further growth of our operations to support our user base, our expanding third-party relationships, our information technology systems and our internal controls and procedures may not be adequate to support our operations. In addition, as we continue to grow, we face challenges of integrating, developing and motivating a rapidly growing employee base in various countries around the world. Certain members of our management have not previously worked together for an extended period of time, and some do not have experience managing a public company, which may affect how they manage our growth. Managing our growth will also require significant expenditures and allocation of valuable management resources.

In addition, our rapid growth may make it difficult to evaluate our future prospects. Our ability to forecast our future results of operations is subject to a number of uncertainties, including our ability to effectively plan for and model future growth. We have encountered in the past, and may encounter in the future, risks and uncertainties frequently experienced by growing companies in rapidly changing industries. If we fail to achieve the necessary level of efficiency in our organization as it grows, or if we are not able to accurately forecast future growth, our business would be harmed.

Our ability to sell subscriptions to our platform could be harmed by real or perceived material defects or errors in our platform.

The software 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 platform or new products may be detected in the future by us or our users. There can be no assurance that our existing platform and new products will not contain defects. Any real or perceived errors, failures, vulnerabilities, or bugs in our platform 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 would harm our business.

We also utilize hardware purchased or leased and software and services licensed from third parties to offer our platform. Any defects in, or unavailability of, our or third-party hardware, software or services that cause interruptions to the availability of our services, loss of data or performance issues could, among other things:

21

If we were to lose the services of our Chief Executive Officer or other members of our senior management team, we may not be able to execute our business strategy.

Our success depends in a large part upon the continued service of key members of our senior management team. In particular, our founder, President and Chief Executive Officer, Eric S. Yuan, is critical to our overall management, as well as the continued development of our products, services, the Zoom platform, our culture, our strategic direction, engineering and our operations in China. All of our executive officers are at-will employees, and we do not maintain any key person life insurance policies. The loss of any member of our senior management team would harm our business.

The failure to attract and retain additional qualified personnel or to maintain our happiness-centric company culture could harm our business and culture and prevent us from executing our business strategy.

To execute our business strategy, we must attract and retain highly qualified personnel. Competition for executives, software developers, sales personnel and other key employees in our industry is intense. In particular, we compete with many other companies for software developers with high levels of experience in designing, developing and managing software for communication and collaboration technologies, as well as for skilled sales and operations professionals. At times, we have experienced, and we may continue to experience, difficulty in hiring and retaining employees with appropriate qualifications, and we may not be able to fill positions. For example, our former Head of Worldwide Sales recently transitioned from this position and as one of our executive officers to a corporate strategy role with us, and while he will continue to be a key contributor, we will need to spend significant resources on recruiting a new Head of Worldwide Sales or role with similar responsibility. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business could be harmed.

Many of the companies with which we compete for experienced personnel have greater resources than we have, and some of these companies may offer greater compensation packages. Particularly in the San Francisco Bay Area, job candidates and existing employees carefully consider the value of the equity awards they receive in connection with their employment. If the perceived value of our equity awards declines, or if the mix of equity and cash compensation that we offer is unattractive, it may adversely affect our ability to recruit and retain highly skilled employees. Job candidates may also be threatened with legal action under agreements with their existing employers if we attempt to hire them, which could impact hiring and result in a diversion of our time and resources. Additionally, laws and regulations, such as restrictive immigration laws, may limit our ability to recruit internationally. We must also continue to retain and motivate existing employees through our compensation practices, company culture and career development opportunities. If we fail to attract new personnel or to retain our current personnel, our business would be harmed.

We believe that a critical component to our success and our ability to retain our best people is our culture. As we continue to grow and develop a public company infrastructure, we may find it difficult to maintain our happiness-centric company culture. Transparency is also an important part of our culture, and one that we practice every day. As we continue to grow, maintaining this culture of transparency will present its own challenges that we will need to address, including the type of information and level of detail that we share with our employees. For example, we were recently informed of a personal relationship involving our Chief Financial Officer and an individual with whom she worked, while they were both at her prior employer. After reviewing the facts and circumstances of the situation, we confirmed that our Chief Financial Officer can and should continue to serve in her role. However, these are the types of situations that will continue to challenge our culture of transparency, especially as we become a public company and operate under the rules and responsibilities to which public companies are subject.

22

In addition, many of our employees may be able to receive significant proceeds from sales of our equity in the public markets after our initial public offering, which may reduce their motivation to continue to work for us. Moreover, this offering could create disparities in wealth among our employees, which may harm our culture and relations among employees and our business.

We are continuing to expand our operations outside the United States, where we may be subject to increased business and economic risks that could harm our business.

We have customers in over 180 countries, and 18% of our revenue in the fiscal year ended January 31, 2019 was generated from customers in APAC and EMEA. In fiscal 2018, we established a physical sales presence in Australia and the United Kingdom. Additionally, as of January 31, 2019, we had five additional international sales locations, and we plan to add local sales support in further select international markets over time. We also operate research and development centers in China, employing over 500 employees as of January 31, 2019. We expect to continue to expand our international operations, which may include opening offices in new jurisdictions and providing our platform in additional languages. Any new markets or countries into which we attempt to sell subscriptions to our platform may not be receptive. For example, we may not be able to expand further in some markets if we are not able to satisfy certain government- and industry-specific requirements. In addition, our ability to manage our business and conduct our operations internationally in the future may require considerable management attention and resources and is subject to the particular challenges of supporting a rapidly growing business in an environment of multiple languages, cultures, customs, legal and regulatory systems, alternative dispute systems and commercial markets. Future international expansion will require investment of significant funds and other resources. Operating internationally subjects us to new risks and may increase risks that we currently face, including risks associated with:

23

Compliance with laws and regulations applicable to our global operations substantially increases our cost of doing business in international jurisdictions. We may be unable to keep current with changes in laws and regulations as they occur. Although we have implemented policies and procedures designed to support compliance with these laws and regulations, there can be no assurance that we will always maintain compliance or that all of our employees, contractors, partners and agents will comply. Any violations could result in enforcement actions, fines, civil and criminal penalties, damages, injunctions or reputational harm. If we are unable to comply with these laws and regulations or manage the complexity of our global operations successfully, we may need to relocate or cease operations in certain foreign jurisdictions. For example, our product development team is largely based in China, where personnel costs are less expensive than in many other jurisdictions. If we had to relocate our product development team from China to another jurisdiction, we could experience, among other things, higher operating expenses, which would adversely impact our operating margins and harm our business. In addition, we would need to spend considerable time and effort recruiting a new product development team, which would distract management and adversely impact our ability to continue improving our platform’s features and functionality.

Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.

Our quarterly results of operations may vary significantly in the future, and period-to-period comparisons of our results of operations may not be meaningful. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly results of operations may fluctuate as a result of a variety of factors, many of which are outside of our control, and as a result, may not fully reflect the underlying performance of our business. Fluctuation in quarterly results may negatively impact the value of our securities. Factors that may cause fluctuations in our quarterly results of operations include, without limitation, those listed below:

24

We recognize revenue from subscriptions to our platform over the terms of these subscriptions. Consequently, increases or decreases in new sales may not be immediately reflected in our results of operations and may be difficult to discern.

We recognize revenue from subscriptions to our platform over the terms of these subscriptions. As a result, a portion of the revenue we report in each quarter is derived from the recognition of deferred revenue relating to subscriptions entered into during previous quarters. Consequently, a decline in new or renewed subscriptions in any single quarter may have a small impact on the revenue that we recognize for that quarter. However, such a decline will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and potential changes in our pricing policies or rate of customer expansion or retention may not be fully reflected in our results of operations until future periods. In addition, a significant portion of our costs are expensed as incurred, while revenue is recognized over the term of the subscription. As a result, growth in the number of new customers and hosts could continue to result in our recognition of higher costs and lower revenue in the earlier periods of our subscriptions. Finally, our subscription-based revenue model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers or from existing customers that increase their use of our platform or upgrade to a higher-priced tier of Zoom Meeting plan must be recognized over the applicable subscription term.

Any failure to offer high-quality support for our customers and hosts may harm our relationships with our customers and hosts and, consequently, our business.

We have designed our platform to be easy to adopt and use with minimal to no support necessary. However, if we experience increased user demand for support, we may face increased costs that may harm our results of operations. In addition, as we continue to grow our operations and support our global user base, we need to be able to continue to provide efficient support that meets our customers and hosts’ needs globally at scale. Customers and hosts receive additional support features, and the number of our hosts has grown significantly, which will put additional pressure on our support organization. If we are unable to provide efficient user support globally at scale or if we need to hire additional support personnel, our business may be harmed. Our new customer and host signups are highly dependent on our business reputation and on positive recommendations from our existing customers and hosts. Any failure to maintain high-quality support, or a market perception that we do not maintain high-quality support for our customers and hosts, would harm our business.

Our actual or perceived failure to comply with privacy, data protection and information security laws, regulations, and obligations could harm our business.

We receive, store, process and use personal information and other user content. There are numerous federal, state, local and international laws and regulations regarding privacy, data protection, information security and the

25

storing, sharing, use, processing, transfer, disclosure and protection of personal information and other content, the scope of which is changing, subject to differing interpretations and may be inconsistent among countries, or conflict with other rules. We are also subject to the terms of our privacy policies and obligations to third parties related to privacy, data protection and information security. We strive to comply with applicable laws, regulations, policies and other legal obligations relating to privacy, data protection and information security to the extent possible. However, the regulatory framework for privacy and data protection worldwide is, and is likely to remain, uncertain for the foreseeable future, and it is possible that these or other actual or alleged obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices.

We also expect that there will continue to be new laws, regulations and industry standards concerning privacy, data protection and information security proposed and enacted in various jurisdictions. For example, in May 2018, the General Data Protection Regulation (GDPR) went into effect in the European Union (EU). The GDPR imposed more stringent data protection requirements and provides greater penalties for noncompliance than previous data protection laws, including potential penalties of up to €20 million or 4% of annual global revenues. Further, following a referendum in June 2016 in which voters in the United Kingdom approved an exit from the EU, the United Kingdom government has initiated a process to leave the EU, known as Brexit. Brexit has created uncertainty with regard to the regulation of data protection in the United Kingdom. In particular, although the United Kingdom enacted a Data Protection Act in May 2018 that is designed to be consistent with the GDPR, uncertainty remains regarding how data transfers to and from the United Kingdom will be regulated. Additionally, although we have self-certified under the U.S.-EU and U.S.-Swiss Privacy Shield Frameworks with regard to our transfer of certain personal data from the EU and Switzerland to the United States, some regulatory uncertainty remains surrounding the future of data transfers from the EU and Switzerland to the United States, and we are monitoring regulatory developments in this area. California also recently enacted legislation, the California Consumer Privacy Act of 2018 (CCPA), that will afford consumers expanded privacy protections when it goes into effect on January 1, 2020. The CCPA was recently amended, and it is possible that it will be amended again before it goes into effect. The potential effects of this legislation are far-reaching and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. For example, the CCPA gives California residents expanded rights to access and require deletion of their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used. The CCPA also provides for civil penalties for violations, as well as a private right of action for data breaches that may increase data breach litigation.

With laws and regulations such as the GDPR in the EU and the CCPA in the United States imposing new and relatively burdensome obligations, and with substantial uncertainty over the interpretation and application of these and other laws and regulations, we may face challenges in addressing their requirements and making necessary changes to our policies and practices, and may incur significant costs and expenses in an effort to do so. Any failure or perceived failure by us to comply with our privacy policies, our privacy-, data protection- or information security-related obligations to users or other third parties or any of our other legal obligations relating to privacy, data protection or information security 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 or cause our users to lose trust in us, which could have an adverse effect on our reputation and business. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations and policies that are applicable to the businesses of our users may limit the adoption and use of, and reduce the overall demand for, our platform.

Additionally, if third parties we work with, such as vendors or developers, violate applicable laws or regulations or our policies, such violations may also put our users’ content at risk and could in turn have an adverse effect on our business. Any significant change to applicable laws, regulations or industry practices regarding the collection, use, retention, security or disclosure of our users’ content, or regarding the manner in which the express or implied consent of users for the collection, use, retention or disclosure of such content is obtained, could increase our costs and require us to modify our services and features, possibly in a material

26

manner, which we may be unable to complete and may limit our ability to store and process user data or develop new services and features.

Our results of operations may be harmed if we are required to collect sales or other related taxes for our subscription services in jurisdictions where we have not historically done so.

We collect sales tax in a number of jurisdictions. One or more states or countries may seek to impose incremental or new sales, use, or other tax collection obligations on us. A successful assertion by a state, country or other jurisdiction that we should have been or should be collecting additional sales, use, or other taxes could, among other things, result in substantial tax payments, create significant administrative burdens for us, discourage potential customers from subscribing to our platform due to the incremental cost of any such sales or other related taxes, or otherwise harm our business.

We may be subject to liabilities on past sales for taxes, surcharges and fees.

We currently collect and remit applicable sales tax in jurisdictions where we, through our employees, have a presence and where we have determined, based on legal precedents in the jurisdiction, that sales of our platform are classified as taxable. We do not currently collect and remit other state and local excise, utility user and ad valorem taxes, fees or surcharges that may apply to our customers and hosts. We believe that we are not otherwise subject to, or required to collect, any additional taxes, fees or surcharges imposed by state and local jurisdictions because we do not have a sufficient physical presence or “nexus” in the relevant taxing jurisdiction or such taxes, fees, or surcharges do not apply to sales of our platform in the relevant taxing jurisdiction. However, there is uncertainty as to what constitutes sufficient physical presence or nexus for a state or local jurisdiction to levy taxes, fees and surcharges for sales made over the internet, and there is also uncertainty as to whether our characterization of our platform as not taxable in certain jurisdictions will be accepted by state and local taxing authorities. Additionally, we have not historically collected value-added tax (VAT) or goods and services tax (GST) on sales of our platform because we make all of our sales through our office in the United States, and we believe, based on information provided to us by our customers, that most of our sales are made to business customers.

Taxing authorities may challenge our position that we do not have sufficient nexus in a taxing jurisdiction or that our platform is not taxable in the jurisdiction and may decide to audit our business and operations with respect to sales, use, telecommunications, VAT, GST and other taxes, which could result in increased tax liabilities for us or our customers and hosts, which could harm our business.

The application of indirect taxes (such as sales and use tax, VAT, GST, business tax and gross receipt tax) to businesses that transact online, such as ours, is a complex and evolving area. Following the recent U.S. Supreme Court decision in South Dakota v. Wayfair, Inc., states are now free to levy taxes on sales of goods and services based on an “economic nexus,” regardless of whether the seller has a physical presence in the state. As a result, it may be necessary to reevaluate whether our activities give rise to sales, use and other indirect taxes as a result of any nexus in those states in which we are not currently registered to collect and remit taxes. Additionally, we may need to assess our potential tax collection and remittance liabilities based on existing economic nexus laws’ dollar and transaction thresholds. We continue to analyze our exposure for such taxes and liabilities and have accrued $8.9 million and $22.0 million for the fiscal years ended January 31, 2018 and 2019, respectively, for loss contingencies resulting from these potential taxes and liabilities. The application of existing, new, or future laws, whether in the U.S. or internationally, could harm our business. There have been, and will continue to be, substantial ongoing costs associated with complying with the various indirect tax requirements in the numerous markets in which we conduct or will conduct business.

27

We are subject to governmental export and import controls that could impair our ability to compete in international markets due to licensing requirements and subject us to liability if we are not in compliance with applicable laws.

Our platform and associated products are subject to various restrictions under U.S. export control and sanctions laws and regulations, including the U.S. Department of Commerce’s Export Administration Regulations (EAR) and various economic and trade sanctions regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC). The U.S. export control laws and U.S. economic sanctions laws include restrictions or prohibitions on the sale or supply of certain products and services to U.S. embargoed or sanctioned countries, governments, persons and entities, and also require authorization for the export of certain encryption items. In addition, various countries regulate the import of certain encryption technology, including through import permitting and licensing requirements and have enacted or could enact laws that could limit our ability to distribute our platform or could limit our hosts’ ability to implement our platform in those countries.

Although we take precautions to prevent our platform and associated products from being accessed or used in violation of such laws, we have inadvertently allowed our platform and associated products to be accessed or used by some customers in apparent violation of U.S. economic sanction laws. In addition, we may have inadvertently made our software products available to some customers, including users in embargoed or sanctioned countries, in apparent violation of the EAR. As a result, we have submitted initial and final voluntary self-disclosures concerning potential violations of U.S. sanctions and export control laws and regulations to OFAC and the U.S. Department of Commerce’s Bureau of Industry and Security. If we are found to be in violation of U.S. economic sanctions or export control laws, it could result in fines and penalties. We may also be adversely affected through other penalties, reputational harm, loss of access to certain markets or otherwise. While we are working to implement additional controls designed to prevent similar activity from occurring in the future, these controls may not be fully effective.

Changes in our platform, or changes in export, sanctions and import laws, may delay the introduction and sale of subscriptions to our platform in international markets, prevent our customers with international operations from using our platform or, in some cases, prevent the access or use of our platform to and from certain countries, governments, persons or entities altogether. Further, any change in export or import regulations, economic sanctions or related laws, shift in the enforcement or scope of existing regulations or change in the countries, governments, persons or technologies targeted by such regulations could result in decreased use of our platform or in our decreased ability to export or sell our platform to existing or potential customers with international operations. Any decreased use of our platform or limitation on our ability to export or sell our platform would likely harm our business.

We utilize our network of resellers to sell our products and services, and our failure to effectively develop, manage and maintain our indirect sales channels would harm our business.

Our future success depends on our continued ability to establish and maintain a network of channel relationships, and we expect that we will need to maintain and expand our network as we expand into international markets. A small portion of our revenue is derived from our network of sales agents and resellers, which we refer to collectively as resellers, many of which sell or may in the future decide to sell their own products and services or services from other communications solutions providers. Loss of or reduction in sales through these third parties could reduce our revenue. Our competitors may in some cases be effective in causing our reseller or potential reseller to favor their products and services or prevent or reduce sales of our products and services. Recruiting and retaining qualified resellers in our network and training them in our technology and product offerings requires significant time and resources. If we decide to further develop and expand our indirect sales channels, we must continue to scale and improve our processes and procedures to support these channels, including investment in systems and training. Many resellers may not be willing to invest the time and resources required to train their staff to effectively sell our platform. If we fail to maintain relationships with our resellers,

28

fail to develop relationships with new resellers in new markets or expand the number of resellers in existing markets or fail to manage, train, or provide appropriate incentives to our existing resellers, our ability to increase the number of new customers and hosts and increase sales to existing customers could be adversely impacted, which would harm our business.

Our results of operations, which are reported in U.S. dollars, could be adversely affected if currency exchange rates fluctuate substantially in the future.

We sell to customers globally and have international operations primarily in Australia, China and the United Kingdom. As we continue to expand our international operations, we will become more exposed to the effects of fluctuations in currency exchange rates. Although the majority of our cash generated from revenue is denominated in U.S. dollars, a small amount is denominated in foreign currencies, and our expenses are generally denominated in the currencies of the jurisdictions in which we conduct our operations. For the fiscal year ended January 31, 2019, 6.4% of our revenue and 12.3% of our expenses were denominated in currencies other than U.S. dollars. 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 impact our results of operations. We do not currently maintain a program to hedge exposures to non-U.S. dollar currencies.

Our current products, as well as products, features and functionality that we may introduce in the future, may not be widely accepted by our customers and hosts or may receive negative attention or may require us to compensate or reimburse third parties, any of which may lower our margins and harm our business.

Our ability to engage, retain and increase our base of customers and hosts and to increase our revenue will depend on our ability to successfully create new products, features and functionality, both independently and together with third parties. We may introduce significant changes to our existing products or develop and introduce new and unproven products, including technologies with which we have little or no prior development or operating experience. These new products and updates may fail to engage, retain and increase our base of customers and hosts or may create lag in adoption of such new products. New products may initially suffer from performance and quality issues that may negatively impact our ability to market and sell such products to new and existing customers and hosts. The short- and long-term impact of any major change to our products, or the introduction of new products, is particularly difficult to predict. If new or enhanced products fail to engage, retain and increase our base of customers and hosts, we may fail to generate sufficient revenue, operating margin or other value to justify our investments in such products, any of which may harm our business in the short term, long term, or both.

In addition, our current products, as well as products, features and functionality that we may introduce in the future, may require us to compensate or reimburse third parties. For example, our new cloud phone system, Zoom Phone, is a private branch exchange phone solution that requires us to compensate carriers that operate the public switched telephone network. As a result, a portion of the payments that we will receive from customers that will use our Zoom Phone product will be allocated towards compensating these telephone carriers, which lowers our margins for Zoom Phone as compared to our other products. In addition, new products that we introduce in the future may similarly require us to compensate or reimburse third parties, all of which would lower our profit margins for any such new products. If this trend continues with our new and existing products, including Zoom Phone, it could harm our business.

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

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

29

not prove to be accurate. Not every organization covered by our market opportunity estimates will necessarily buy video communications platforms at all, and some or many of those organizations may choose to continue using legacy communication methods or point solutions offered by our competitors. It is impossible to build every product feature that every customer or host wants, and our competitors may develop and offer features that our platform does not provide. The variables that go into the calculation of our market opportunity are subject to change over time, and there is no guarantee that any particular number or percentage of the organizations covered by our market opportunity estimates will purchase our solutions at all or generate any particular level of revenue for us. Even if the market in which we compete meets the size estimates and growth forecasts in this prospectus, our business could fail to grow for a variety of reasons outside of our control, including competition in our industry. If any of these risks materialize, it could harm our business and prospects. For more information regarding the estimates of market opportunity and the forecasts of market growth included in this prospectus, see the section titled “Market and Industry Data.”

We may be subject to, or assist law enforcement with enforcement of, a variety of U.S. and international laws that could result in claims, increase the cost of operations or otherwise harm our business due to changes in the laws, changes in the interpretations of the laws, greater enforcement of the laws or investigations into compliance with the laws.

We may be subject to, or assist law enforcement with enforcement of, various laws, including those covering copyright, indecent content, child protection, consumer protection, telecommunications services, taxation and similar matters. There have been instances where improper or illegal content has been shared on our platform without our knowledge. As a service provider, we do not regularly monitor our platform to evaluate the legality of content shared on it. While to date we have not been subject to material legal or administrative actions as a result of this content, the laws in this area are currently in a state of flux and vary widely between jurisdictions. Accordingly, it may be possible that in the future we and our competitors may be subject to legal actions, along with the users who shared such content. In addition, regardless of any legal liability we may face, our reputation could be harmed should there be an incident generating extensive negative publicity about the content shared on our platform. Such publicity would harm our business.

We are also subject to consumer protection laws that may impact our sales and marketing efforts, including laws related to subscriptions, billing and auto-renewal. These laws, as well as any changes in these laws, could adversely affect our self-serve model and make it more difficult for us to retain and upgrade customers and attract new customers and hosts. Additionally, we have in the past, are currently and may from time to time in the future become the subject of inquiries and other actions by regulatory authorities as a result of our business practices, including our subscription, billing and auto-renewal policies. Consumer protection laws may be interpreted or applied by regulatory authorities in a manner that could require us to make changes to our operations or incur fines, penalties or settlement expenses, which may result in harm to our business.

Our platform depends on the ability of our customers, hosts and users to access the internet, and our platform has been blocked or restricted in some countries for various reasons. If we fail to anticipate developments in the law, or fail for any reason to comply with relevant law, our platform could be further blocked or restricted, and we could be exposed to significant liability that could harm our business.

We are also subject to various U.S. and international anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, as well as other similar anti-bribery and anti-kickback laws and regulations. These laws and regulations generally prohibit companies and their employees and intermediaries from authorizing, offering or providing improper payments or benefits to officials and other recipients for improper purposes. Although we take precautions to prevent violations of these laws, our exposure for violating these laws increases as we continue to expand our international presence, and any failure to comply with such laws could harm our business.

30

Zoom Phone is subject to U.S. federal and international regulation, and other products we may introduce in the future may also be subject to U.S. federal, state or international laws, rules and regulations. Any failure to comply with such laws, rules and regulations could harm our business and expose us to liability.

Federal Regulation

Our recently introduced product, Zoom Phone, is provided through our wholly owned subsidiary, Zoom Voice Communications, Inc., which is regulated by the FCC as an interconnected voice over internet protocol (VoIP) service provider. As a result, Zoom Phone is subject to existing or potential FCC regulations, including but not limited to regulations relating to privacy, disability access, porting of numbers, federal Universal Service Fund (USF), contributions and other regulatory assessments, emergency calling/Enhanced 911 (E-911) and law enforcement access. Congress or the FCC may expand the scope of Zoom Phone’s regulatory obligations at any time. In addition, FCC classification of Zoom Phone as a common carrier or telecommunications service could result in additional federal and state regulatory obligations. If we do not comply with any current or future state regulations that apply to our business, we could be subject to substantial fines and penalties, we may have to restructure our product offerings, exit certain markets or raise the price of our products, any of which could ultimately harm our business and results of operations. Any enforcement action by the FCC, which may be a public process, would hurt our reputation in the industry, possibly impair our ability to sell Zoom Phone to our customers and harm our business.

State Regulation

State telecommunications regulation of Zoom Phone is generally preempted by the FCC. However, states are allowed to assess state USF contributions, E-911 fees and other surcharges. A number of states require us to contribute to state USF and pay E-911 and other assessments and surcharges, while others are actively considering extending their programs to include the products we offer. We generally pass USF, E-911 fees and other surcharges through to our customers where we are permitted to do so, which may result in our products becoming more expensive. We expect that state public utility commissions will continue their attempts to apply state telecommunications regulations to services like Zoom Phone. If we do not comply with any current or future state regulations that apply to our business, we could be subject to substantial fines and penalties, we may have to restructure our product offerings, exit certain markets or raise the price of our products, any of which could harm our business.

International Regulation

As we expand internationally, we may be subject to telecommunications, consumer protection, privacy, data protection and other laws and regulations in the foreign countries where we offer our products. In the future, we intend to offer Zoom Phone internationally. If we do not comply with any current or future international regulations that apply to our business, we could be subject to substantial fines and penalties, we may have to restructure our product offerings, exit certain markets or raise the price of our products, any of which could harm our business.

We are currently, and may be in the future, party to intellectual property rights claims and other litigation matters, which, if resolved adversely, could harm our business.

We protect our intellectual property through patents, copyrights, trademarks, domain names and trade secrets and, from time to time, are subject to litigation based on allegations of infringement, misappropriation or other violations of intellectual property or other rights. As we face increasing competition and gain an increasingly high profile, the possibility of intellectual property rights claims, commercial claims and other assertions against us grows. We have in the past been, are currently, and may from time to time in the future become, a party to litigation and disputes related to our intellectual property, our business practices and our platform. For example, on February 28, 2019, Wave Linx LLC (Wave Linx) filed a lawsuit against us in the U.S. District Court for the District of Delaware alleging that we infringe a patent owned by Wave Linx. Also, on April 5, 2019, Krush Technologies, Inc. (Krush) filed a lawsuit against us in the Northern District Court of California, alleging that we infringe three patents that Krush acquired. Krush is seeking a permanent injunction

31

against infringement, treble damages and attorneys’ fees. While we intend to defend these lawsuits vigorously and believe that we have valid defenses to these claims, litigation can be costly and time-consuming, divert the attention of our management and key personnel from our business operations and dissuade potential customers from subscribing to our services, which would harm our business. Furthermore, with respect to these lawsuits, there can be no assurances that favorable outcomes will be obtained. We may need to settle litigation and disputes on terms that are unfavorable to us, or we may be subject to an unfavorable judgment that may not be reversible upon appeal. The terms of any settlement or judgment may require us to cease some or all of our operations or pay substantial amounts to the other party. In addition, our agreements with certain larger customers include certain provisions for indemnifying them against liabilities if our services infringe a third party’s intellectual property rights, which could require us to make payments to our customers. During the course of any litigation or dispute, we may make announcements regarding the results of hearings and motions and other interim developments. If securities analysts and investors regard these announcements as negative, the market price of our Class A common stock may decline. With respect to any intellectual property rights claim, we may have to seek a license to continue practices found to be in violation of third-party rights, which may not be available on reasonable terms and may significantly increase our operating expenses. A license to continue such practices may not be available to us at all, and we may be required to develop alternative non-infringing technology or practices or discontinue the practices. The development of alternative, non-infringing technology or practices could require significant effort and expense. Our business could be harmed as a result.

Our failure to protect our intellectual property rights and proprietary information could diminish our brand and other intangible assets.

We primarily rely and expect to continue to rely on a combination of patent, patent licenses, trade secret and domain name protection, trademark and copyright laws, as well as confidentiality and license agreements with our employees, consultants and third parties, to protect our intellectual property and proprietary rights. In the United States and abroad, as of March 22, 2019, we have two issued patents and seven pending patent applications. We make business decisions about when to seek patent protection for a particular technology and when to rely upon copyright or trade secret protection, and the approach we select may ultimately prove to be inadequate. Even in cases where we seek patent protection, there is no assurance that the resulting patents will effectively protect every significant feature of our products. In addition, we believe that the protection of our trademark rights is an important factor in product recognition, protecting our brand and maintaining goodwill. If we do not adequately protect our rights in our trademarks from infringement and unauthorized use, any goodwill that we have developed in those trademarks could be lost or impaired, which could harm our brand and our business. Third parties may knowingly or unknowingly infringe our proprietary rights, third parties may challenge our proprietary rights, pending and future patent, trademark and copyright applications may not be approved, and we may not be able to prevent infringement without incurring substantial expense. We have also devoted substantial resources to the development of our proprietary technologies and related processes. In order to protect our proprietary technologies and processes, we rely in part on trade secret laws and confidentiality agreements with our employees, consultants and third parties. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets, in which case we would not be able to assert trade secret rights, or develop similar technologies and processes. Further, laws in certain jurisdictions may afford little or no trade secret protection, and any changes in, or unexpected interpretations of, the intellectual property laws in any country in which we operate may compromise our ability to enforce our intellectual property rights. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights. If the protection of our proprietary rights is inadequate to prevent use or appropriation by third parties, the value of our platform, brand and other intangible assets may be diminished, and competitors may be able to more effectively replicate our platform and its features. Any of these events would harm our business.

If we experience excessive fraudulent activity or cannot meet evolving credit card association merchant standards, we could incur substantial costs and lose the right to accept credit cards for payment, which could cause our customer and paid host base to decline significantly.

A large portion of our customers authorize us to bill their credit card accounts directly for our products. If customers pay for their subscriptions with stolen credit cards, we could incur substantial third-party vendor costs

32

for which we may not be reimbursed. Further, our customers provide us with credit card billing information online or over the phone, and we do not review the physical credit cards used in these transactions, which increases our risk of exposure to fraudulent activity. We also incur charges, which we refer to as chargebacks, from the credit card companies for claims that the customer did not authorize the credit card transaction for our products, something that we have experienced in the past. If the number of claims of unauthorized credit card transactions becomes excessive, we could be assessed substantial fines for excess chargebacks, and we could lose the right to accept credit cards for payment. In addition, credit card issuers may change merchant standards, including data protection and documentation standards, required to utilize their services from time to time. If we fail to maintain compliance with current merchant standards or fail to meet new standards, the credit card associations could fine us or terminate their agreements with us, and we would be unable to accept credit cards as payment for our products. Our products may also be subject to fraudulent usage and schemes, including third parties accessing customer accounts or viewing and recording data from our communications solutions. These fraudulent activities can result in unauthorized access to customer accounts and data, unauthorized use of our products, and charges and expenses to customers for fraudulent usage. We may be required to pay for these charges and expenses with no reimbursement from the customer, and our reputation may be harmed if our products are subject to fraudulent usage. Although we implement multiple fraud prevention and detection controls, we cannot assure you that these controls will be adequate to protect against fraud. Substantial losses due to fraud or our inability to accept credit card payments would cause our customer base to significantly decrease and would harm our business.

Our business may be significantly impacted by a change in the economy, including any resulting effect on consumer or business spending.

Our business may be affected by changes in the economy generally, including any resulting effect on spending by our customers. While some of our customers may consider our platform to be a cost-saving purchase, decreasing the need for business travel, others may view a subscription to our platform as a discretionary purchase, and our customers may reduce their discretionary spending on our platform during an economic downturn. If an economic downturn were to occur, we may experience such a reduction in demand and loss of customers, especially in the event of a prolonged recessionary period.

Our business could be disrupted by catastrophic events.

Occurrence of any catastrophic event, including earthquake, fire, flood, tsunami or other weather event, power loss, telecommunications failure, software or hardware malfunctions, cyber-attack, war or terrorist attack, could result in lengthy interruptions in our service. In particular, our U.S. headquarters and some of the data centers we utilize are located in the San Francisco Bay Area, a region known for seismic activity, and our insurance coverage may not compensate us for losses that may occur in the event of an earthquake or other significant natural disaster. In addition, acts of terrorism could cause disruptions to the internet or the economy as a whole. Even with our disaster recovery arrangements, our service could be interrupted. If our systems were to fail or be negatively impacted as a result of a natural disaster or other event, our ability to deliver products to our users would be impaired, or we could lose critical data. 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.

We may have exposure to greater than anticipated tax liabilities, which could harm our business.

While to date we have not incurred significant income taxes in operating our business, we are subject to income taxes in the United States and various jurisdictions outside of the United States. Our effective tax rate could fluctuate due to changes in the proportion of our earnings and losses in countries with differing statutory tax rates. Our tax expense could also be impacted by changes in non-deductible expenses, changes in excess tax benefits of stock-based compensation, changes in the valuation of, or our ability to use, deferred tax assets and liabilities, the applicability of withholding taxes and effects from acquisitions.

33

The provision for taxes on our financial statements could also be impacted by changes in accounting principles, changes in U.S. federal, state or international tax laws applicable to corporate multinationals such as the recent legislation enacted in Australia, the United Kingdom and the United States, other fundamental changes in law currently being considered by many countries and changes in taxing jurisdictions’ administrative interpretations, decisions, policies and positions.

We are subject to review and audit by U.S. federal, state, local and foreign tax authorities. Such tax authorities may disagree with tax positions we take, and if any such tax authority were to successfully challenge any such position, our business could be harmed. We may also be subject to additional tax liabilities due to changes in non-income based taxes resulting from changes in federal, state or international tax laws, changes in taxing jurisdictions’ administrative interpretations, decisions, policies and positions, results of tax examinations, settlements or judicial decisions, changes in accounting principles, changes to our business operations, including acquisitions, as well as the evaluation of new information that results in a change to a tax position taken in a prior period.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of January 31, 2019, we had $26.9 million of U.S. federal and $10.7 million of state net operating loss carryforwards available to reduce future taxable income, which will begin to expire in 2032 for federal and 2027 for state tax purposes. It is possible that we will not generate taxable income in time to use these net operating loss carryforwards before their expiration or at all. Under legislative changes made in December 2017, U.S. federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such net operating losses is limited. It is uncertain if and to what extent various states will conform to the newly enacted federal tax law. In addition, the federal and state net operating loss carryforwards and certain tax credits may be subject to significant limitations under Section 382 and Section 383 of the Internal Revenue Code of 1986, as amended (the Code), respectively, and similar provisions of state law. Under those sections of the Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset its post-change income or tax may be limited. In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We have completed a Section 382 calculation and have determined that none of the operating losses will expire solely due to Section 382 limitation(s). However, we may experience ownership changes as a result of this offering or in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability to use our net operating loss carryforwards and tax credits is materially limited, it would harm our business by effectively increasing our future tax obligations.

Our reported results of operations may be adversely affected by changes in accounting principles generally accepted in the United States.

Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board (FASB), the Securities and Exchange Commission (SEC) and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported results of operations and may even affect the reporting of transactions completed before the announcement or effectiveness of a change. For example, we recently adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (ASC 606), effective as of February 1, 2017, utilizing the full retrospective method of adoption. The adoption of ASC 606 impacted the timing and manner in which we report our revenue and expenses, especially with respect to our sales commissions. See Note 1 to our consolidated financial statements included elsewhere in this prospectus for more information. It is also difficult to predict the impact of future changes to accounting principles or our accounting policies, any of which could harm our business.

34

We may need additional capital, and we cannot be certain that additional financing will be available on favorable terms, or at all.

Historically, we have funded our operations and capital expenditures primarily through equity issuances and cash generated from our operations. Although we currently anticipate that our existing cash and cash equivalents and cash flow from operations will be sufficient to meet our cash needs for the foreseeable future, we may require additional financing. We evaluate financing opportunities from time to time, and our ability to obtain financing will depend, among other things, on our development efforts, business plans, operating performance and condition of the capital markets at the time we seek financing. We cannot assure you that additional financing will be available to us on favorable terms when required, or at all. If we raise additional funds through the issuance of equity or equity-linked or debt securities, those securities may have rights, preferences or privileges senior to the rights of our Class A common stock, and our stockholders may experience dilution.

Our use of third-party open source software could negatively affect our ability to offer and sell subscriptions to our platform and subject us to possible litigation.

A portion of the technologies we use incorporates third-party open source software, and we may incorporate third-party open source software in the future. Open source software is generally licensed by its authors or other third parties under open source licenses. From time to time, companies that use third-party open source software have faced claims challenging the use of such open source software and requesting compliance with the open source software license terms. Accordingly, we may be subject to suits by parties claiming ownership of what we believe to be open source software or claiming non-compliance with the applicable open source licensing terms. Some open source software licenses require end-users who use, distribute or make available across a network software and services that include open source software to offer aspects of the technology that incorporates the open source software for no cost. We may also be required to make publicly available source code (which in some circumstances could include valuable proprietary code) for modifications or derivative works we create based upon, incorporating or using the open source software and/or to license such modifications or derivative works under the terms of the particular open source license. Additionally, if a third-party software provider has incorporated open source software into software that we license from such provider, we could be required to disclose any of our source code that incorporates or is a modification of our licensed software. While we employ practices designed to monitor our compliance with the licenses of third-party open source software and protect our valuable proprietary source code, we may inadvertently use third-party open source software in a manner that exposes us to claims of non-compliance with the terms of their licenses, including claims of intellectual property rights infringement or for breach of contract. Furthermore, there exists today an increasing number of types of open source software licenses, almost none of which have been tested in courts of law to provide guidance of their proper legal interpretations. If we were to receive a claim of non-compliance with the terms of any of these open source licenses, we may be required to publically release certain portions of our proprietary source code. We could also be required to expend substantial time and resources to re-engineer some of our software. Any of the foregoing could disrupt and harm our business.

In addition, the use of third-party open source software typically exposes us to greater risks than the use of third-party commercial software because open source licensors generally do not provide warranties or controls on the functionality or origin of the software. Use of open source software may also present additional security risks because the public availability of such software may make it easier for hackers and other third parties to determine how to compromise our platform. Any of the foregoing could harm our business and could help our competitors develop products and services that are similar to or better than ours.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act), the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act) and the rules

35

and regulations of the applicable listing standards of The Nasdaq Stock Market. We expect that the requirements of these rules and regulations will continue to increase our legal, accounting and financial compliance costs, make some activities more difficult, time-consuming and costly and place significant strain on our personnel, systems and resources.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we will file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that information required to be disclosed in reports under the Exchange Act is accumulated and communicated to our principal executive and financial officers. We are also continuing to improve our internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight.

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. For example, we will need to implement new revenue recognition modules into our existing enterprise resource planning system to facilitate the preparation of our financial statements under ASC 606. We will also be required to adopt ASU 2016-02, Leases (Topic 842), which requires, among other things, lessees to recognize most leases on-balance sheet via a right of use asset and lease liability, beginning February 1, 2019. We have limited experience with implementing the systems and controls that will be necessary to operate as a public company, as well as adopting changes in accounting principles or interpretations mandated by the relevant regulatory bodies. Additionally, if these new systems, controls or standards and the associated process changes do not give rise to the benefits that we expect or do not operate as intended, it could 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.

Further, weaknesses in our disclosure controls and internal control over financial reporting may be discovered in the future. Any failure to develop or maintain effective controls or any difficulties encountered in their implementation or improvement could harm our business or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal control over financial reporting also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we will eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our Class A common stock. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on The Nasdaq Stock Market. We are not currently required to comply with the SEC rules that implement Section 404 of the Sarbanes-Oxley Act and are therefore not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. As a public company, we will be required to provide an annual management report on the effectiveness of our internal control over financial reporting commencing with our second annual report on Form 10-K.

Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until our first annual report filed with the SEC where we are an accelerated filer or a large accelerated filer. At such time, our independent registered public accounting firm may

36

issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting could harm our business and could cause a decline in the trading price of our Class A common stock.

We may acquire other businesses or receive offers to be acquired, which could require significant management attention, disrupt our business or dilute stockholder value.

We may in the future make acquisitions of other companies, products and technologies. We have limited experience in acquisitions. We may not be able to find suitable acquisition candidates and we may not be able to complete acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by users, developers or investors. In addition, we may not be able to integrate acquired businesses successfully or effectively manage the combined company following an acquisition. If we fail to successfully integrate our acquisitions, or the people or technologies associated with those acquisitions, into our company, the results of operations of the combined company could be adversely affected. Any integration process will require significant time and resources, require significant attention from management and disrupt the ordinary functioning of our business, and we may not be able to manage the process successfully, which could harm our business. In addition, we may not successfully evaluate or utilize the acquired technology and accurately forecast the financial impact of an acquisition transaction, including accounting charges.

We may have to pay cash, incur debt or issue equity securities to pay for any such acquisition, each of which could affect our financial condition or the value of our capital stock. The sale of equity to finance any such acquisitions could result in dilution to our stockholders. If we incur more debt, it would result in increased fixed obligations and could also subject us to covenants or other restrictions that would impede our ability to flexibly operate our business.

Risks Related to Ownership of Our Class A Common Stock

An active trading market for our Class A common stock may never develop or be sustained.

We have been approved to list our Class A common stock on The Nasdaq Global Select Market under the symbol “ZM.” However, we cannot assure you that an active trading market for our Class A common stock will develop on that exchange or elsewhere or, if developed, that any market will be sustained. Accordingly, we cannot assure you of the likelihood that an active trading market for our Class A common stock will develop or be maintained, your ability to sell your shares of our Class A common stock when desired or the prices that you may obtain for your shares.

The trading price of our Class A common stock may be volatile, and you could lose all or part of your investment.

Prior to this offering, there has been no public market for shares of our Class A common stock. The initial public offering price of our Class A common stock was determined through negotiation between us and the underwriters. This price does not necessarily reflect the price at which investors in the market will be willing to buy and sell shares of our Class A common stock following this offering. In addition, the trading price of our Class A common stock following this offering 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 common stock as you might be unable to sell your shares at or above the price you paid in this offering. Factors that could cause fluctuations in the trading price of our Class A common stock include the following:

37

In addition, in the past, following periods of volatility in the overall market and in the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

The dual class structure of our common stock as contained in our amended and restated certificate of incorporation has the effect of concentrating voting control with those stockholders who held our stock prior to this offering and the concurrent private placement, including our executive officers, employees and directors and their affiliates, limiting your ability to influence corporate matters.

Our Class B common stock has 10 votes per share, and our Class A common stock, which is the stock we are offering in this initial public offering and the concurrent private placement, has one vote per share. The holders of our outstanding Class B common stock will hold 99.0% of the voting power of our outstanding capital stock following this offering and the concurrent private placement, with our directors, executive officers and 5% stockholders and their respective affiliates holding 61.6% of such voting power in the aggregate. Our founder, President and Chief Executive Officer, Eric S. Yuan, will hold approximately 18.2% of our outstanding capital stock but will control approximately 19.9% of the voting power of our outstanding capital stock following the completion of this offering and the concurrent private placement. Therefore, these holders will have significant influence over our management and affairs and over all matters requiring stockholder approval, including

38

election of directors and significant corporate transactions, such as a merger or other sale of Zoom or our assets, for the foreseeable future. Each share of Class B common stock will be automatically converted into one share of Class A common stock upon the earliest of (i) the date that is six months following the death or incapacity of Mr. Yuan, (ii) the date that is six months following the date that Mr. Yuan is no longer providing services to us or his employment is terminated for cause, (iii) the date specified by the holders of a majority of the then outstanding shares of Class B common stock, voting as a separate class, and (iv) the 15-year anniversary of the closing of our initial public offering.

In addition, the holders of Class B common stock collectively will continue to be able to control all matters submitted to our stockholders for approval even if their stock holdings represent less than a majority of the outstanding shares of our common stock. This concentrated control will limit your ability to influence corporate matters for the foreseeable future, and, as a result, the market price of our Class A common stock could be adversely affected.

Future transfers by holders of Class B common stock will generally result in those shares converting to Class A common stock, which will have the effect, over time, of increasing the relative voting power of those holders of Class B common stock who retain their shares in the long term. If, for example, Mr. Yuan retains a significant portion of his holdings of Class B common stock for an extended period of time, he could, in the future, control a majority of the combined voting power of our Class A and Class B common stock. As a board member, Mr. Yuan owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of our stockholders. As a stockholder, even a controlling stockholder, Mr. Yuan is entitled to vote his shares in his own interests, which may not always be in the interests of our stockholders generally.

In addition, in July 2017, FTSE Russell and Standard & Poor’s announced that they would cease to allow most newly public companies utilizing dual or multi-class capital structures to be included in their indices. Affected indices include the Russell 2000 and the S&P 500, S&P MidCap 400 and S&P SmallCap 600, which together make up the S&P Composite 1500. Under the announced policies, our dual class capital structure would make us ineligible for inclusion in any of these indices, and as a result, mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track these indices will not be investing in our stock. These policies are 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 or depress our trading volume compared to those of other similar companies that are included.

If you purchase our Class A common stock in this offering, you will incur immediate and substantial dilution in the book value of your investment.

The initial public offering price of our Class A common stock is substantially higher than the pro forma net tangible book value per share of our Class A and Class B common stock outstanding immediately following the completion of this offering. Therefore, if you purchase shares of our Class A common stock in this offering at the initial public offering price of $36.00 per share, you will experience immediate dilution of $33.66 per share, the difference between the price per share you pay for our Class A common stock and its pro forma net tangible book value per share as of January 31, 2019, after giving effect to the issuance of shares of our Class A common stock in this offering and the concurrent private placement. This dilution is due in large part to the fact that our earlier investors paid substantially less than the initial public offering price when they purchased their shares of Class B common stock. In addition, we have issued options to acquire our Class B common stock at prices significantly below the initial public offering price. To the extent outstanding options are ultimately exercised, there will be further dilution to investors purchasing our Class A common stock in this offering. In addition, if the underwriters exercise their option to purchase additional shares or if we issue additional equity securities, you will experience additional dilution.

39

Future sales and issuances of our capital stock or rights to purchase capital stock could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to decline.

We may issue additional securities following the completion of this offering. Future sales and issuances of our capital stock or rights to purchase our capital stock could result in substantial dilution to our existing stockholders. We may sell Class A common stock, convertible securities and other equity securities in one or more transactions at prices and in a manner as we may determine from time to time. If we sell any such securities in subsequent transactions, investors may be materially diluted. New investors in such subsequent transactions could gain rights, preferences and privileges senior to those of holders of our Class A common stock.

We will have broad discretion in the use of net proceeds from this offering and the concurrent private placement and may invest or spend the proceeds in ways with which you do not agree and in ways that may not yield a return.

We cannot specify with any certainty the particular uses of the net proceeds that we will receive from this offering and the concurrent private placement. Our management will have broad discretion over the use of net proceeds from this offering and the concurrent private placement, including for any of the purposes described in “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Investors may not agree with our decisions, and our use of the proceeds may not yield any return on your investment. Because of the number and variability of factors that will determine our use of the net proceeds from this offering and the concurrent private placement, their ultimate use may vary substantially from their currently intended use. Our failure to apply the net proceeds of this offering and the concurrent private placement effectively could impair our ability to pursue our growth strategy or could require us to raise additional capital.

Substantial future sales of shares of our Class A common stock and Class B common stock could cause the market price of our Class A common stock to decline.

Sales of a substantial number of shares of our Class A common stock and Class B common stock (after automatically converting to Class A common stock) in the public market following the completion of this offering, or the perception that these sales might occur, could depress the market price of our Class A common stock and could impair our ability to raise capital through the sale of additional equity securities. Many of our existing equityholders have substantial unrecognized gains on the value of the equity they hold based upon the price of this offering, and therefore they may take steps to sell their shares or otherwise secure the unrecognized gains on those shares.

Based on shares outstanding as of January 31, 2019, upon the completion of this offering, we will have outstanding a total of 24,070,086 shares of Class A common stock and 232,318,285 shares of Class B common stock, assuming no exercise of the underwriters’ option to purchase additional shares and no exercise of outstanding options, other than 283,177 shares to be issued upon the exercise of options to purchase Class B common stock by certain selling stockholders and sold in this offering, after giving effect to the conversion of all outstanding shares of our preferred stock into shares of Class B common stock immediately upon the completion of this offering and after giving effect to the conversion of 10,958,131 shares of Class B common stock into Class A common stock upon the sale of such shares by the selling stockholders. Of these shares, only the shares of Class A common stock sold in this offering will be freely tradable, without restriction, in the public market immediately after the offering and the concurrent private placement. All of our executive officers and directors and the holders of substantially all the shares of our capital stock and securities convertible into or exchangeable for our capital stock have entered into market standoff agreements with us or have entered or will enter into lock-up agreements with the underwriters that restrict their ability to transfer shares of our capital stock during the period ending on, and including, the 180^th day after the date of this prospectus, subject to specified exceptions. We refer to such period as the lock-up period. We and the underwriters may permit certain stockholders who are subject to these market standoff agreements or lock-up agreements to sell shares prior to the expiration of the lock-up period. After the end of the lock-up period, all shares of Class A and Class B common stock outstanding as of March 31, 2019 will become eligible for sale, of which 83,045,414 shares held

40

by directors, executive officers and other affiliates will be subject to volume limitations under Rule 144 under the Securities Act of 1933, as amended (the Securities Act) and various vesting agreements.

In addition, as of January 31, 2019, there were 35,064,465 shares of Class B common stock subject to outstanding options. We intend to register all of the shares of Class A common stock issuable upon conversion of the shares of Class B common stock issuable upon exercise of outstanding options and upon exercise or settlement of any options or other equity incentives we may grant in the future for public resale under the Securities Act. Accordingly, these shares will become eligible for sale in the public market to the extent such options are exercised, subject to the lock-up agreements described above and compliance with applicable securities laws.

As of January 31, 2019, holders of 156,171,668 shares of our Class B common stock, including shares issuable upon the conversion of outstanding shares of preferred stock, have rights, subject to some conditions, to require us to file registration statements for the public resale of the Class A common stock issuable upon conversion of such shares or to include such shares in registration statements that we may file on our behalf or for other stockholders. See “Shares Eligible for Future Sale” and “Underwriters.”

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our management or hinder efforts to acquire a controlling interest in us, and the market price of our Class A common stock may be lower as a result.

There are provisions in our certificate of incorporation and bylaws, as they will be in effect following this offering, that may make it difficult for a third party to acquire, or attempt to acquire, control of Zoom, even if a change in control was considered favorable by our stockholders.

Our charter documents will also contain other provisions that could have an anti-takeover effect, such as:

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibit a person who owns 15% or more of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner. Any provision in our certificate of incorporation or our bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our Class A common stock and could also affect the price that some investors are willing to pay for our Class A common stock.

41

Our amended and restated certificate of incorporation will designate the Court of Chancery of the State of Delaware and, to the extent enforceable, the federal district courts of the United States of America as the exclusive forums for certain disputes between us and our stockholders, which could limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation, which will become effective immediately prior to the completion of this offering, will provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the Delaware General Corporation Law, or the certificate of incorporation or the amended and restated bylaws or (iv) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware), in all cases subject to the court having jurisdiction over indispensable parties named as defendants. In addition, our amended and restated certificate of incorporation will provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision.

Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to these provisions. These exclusive-forum provisions may limit a stockholder’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 and our directors, officers and other employees. If a court were to find either exclusive-forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm our results of operations. For example, the Court of Chancery of the State of Delaware recently determined that the exclusive forum provision of federal district courts of the United States of America for resolving any complaint asserting a cause of action arising under the Securities Act is not enforceable. However, this decision may be reviewed and ultimately overturned by the Delaware Supreme Court. If this ultimate adjudication were to occur, we would enforce the federal district court exclusive forum provision in our amended and restated certificate of incorporation.

Our Class A common stock market price and trading volume could decline if securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business.

The trading market for our Class A common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. The analysts’ estimates are based upon their own opinions and are often different from our estimates or expectations. If one or more of the analysts who cover us downgrade our Class A common stock or publish inaccurate or unfavorable research about our business, the price of our securities would likely decline. If few securities analysts commence coverage of us, or if one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our securities could decrease, which might cause the price and trading volume of our Class A common stock to decline.

We will incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies in the United States, which may harm our business.

As a public company listed in the United States, we will incur significant additional legal, accounting and other expenses. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the SEC and The Nasdaq Stock Market, may increase legal and financial compliance costs and make some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, and as a result, their application in practice may evolve over time

42

as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If, notwithstanding our efforts, we fail to comply with new laws, regulations and standards, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Failure to comply with these rules might also make it more difficult for us to obtain certain types of insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events would also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on committees of our board of directors or as members of senior management.

We are an “emerging growth company,” and we intend to comply only with reduced disclosure requirements applicable to emerging growth companies. As a result, our Class A common stock could be less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act, and for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, 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 approval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year (a) following the fifth anniversary of the completion of this offering, (b) in which we have total annual gross revenue of over $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock held by non-affiliates exceeds $700 million as of the prior July 31 and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. We cannot predict if investors will find our Class A common stock less attractive if we choose to rely on these exemptions. If some investors find our Class A common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our Class A common stock, and our stock price may be more volatile.

We do not intend to pay dividends for the foreseeable future.

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. As a result, stockholders must rely on sales of their Class A common stock after price appreciation as the only way to realize any future gains on their investment.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of our Class A common stock that we are offering and the concurrent private placement will be approximately $434.5 million (or approximately $541.5 million if the underwriters exercise their over-allotment option in full), based on the initial public offering price of $36.00 per share of Class A common stock, after deducting underwriting discounts and commissions and estimated expenses related to the offering and the concurrent private placement. We will not receive any proceeds from the sale of shares of our Class A common stock by the selling stockholders.

The principal purposes of this offering are to increase our capitalization and financial flexibility and create a public market for our Class A common stock. We currently intend to use the net proceeds we receive from this offering and the concurrent private placement for general corporate purposes, including working capital, operating expenses and capital expenditures. We cannot specify with certainty all of the particular uses for the remaining net proceeds to us from this offering and the concurrent private placement. We may also use a portion of the net proceeds for acquisitions or strategic investments in complementary businesses, products, services or technologies. However, we do not have agreements or commitments to enter into any such acquisitions or investments at this time. We will have broad discretion over how to use the net proceeds to us from this offering. We intend to invest the net proceeds to us from the offering and the concurrent private placement that are not used as described above in investment-grade, interest-bearing instruments.

DIVIDEND POLICY

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and future earnings, if any, to fund the development and expansion of our business, and we do not anticipate paying any cash dividends in the foreseeable future. Any future determination regarding the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may deem relevant. In addition, we may enter into agreements in the future that could contain restrictions on payments of cash dividends.

46

CAPITALIZATION

The following table sets forth our cash, cash equivalents and marketable securities and our capitalization as of January 31, 2019 as follows:

47

The pro forma and pro forma as adjusted information below is illustrative only, and our capitalization following the completion of this offering will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing. You should read this information in conjunction with our consolidated financial statements and the related notes included in this prospectus and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information contained in this prospectus.

48

The outstanding share information in the table above is based on 422,744 shares of our Class A common stock (including the conversion of convertible promissory notes) and 242,993,239 shares of our Class B common stock (including preferred stock on an as-converted basis and reclassified as common stock) outstanding as of January 31, 2019 and excludes:

49

DILUTION

If you invest in our Class A common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the initial public offering price per share and the pro forma as adjusted net tangible book value per share of our Class A common stock after this offering and the concurrent private placement.

As of January 31, 2019, we had a pro forma net tangible book value (deficit) of $165.3 million, or $0.68 per share. Pro forma net tangible book value per share represents the amount of our total tangible assets less our total liabilities, divided by the number of shares of our Class A and Class B common stock outstanding as of January 31, 2019, after giving effect to the reclassification and automatic conversion of all shares of our convertible preferred stock outstanding as of January 31, 2019 into 152,665,804 shares of our Class B common stock.

After giving further effect to the sale of 12,689,211 shares of Class A common stock that we are offering and the concurrent private placement at the initial public offering price of $36.00 per share, as well as the issuance of 283,177 shares of Class A common stock (as converted) upon exercise of options held by certain selling stockholders, and after deducting underwriting discounts and commissions and estimated expenses related to the offering and the concurrent private placement payable by us, our pro forma as adjusted net tangible book value as of January 31, 2019 would have been approximately $600.0 million, or approximately $2.34 per share. This amount represents an immediate increase in pro forma net tangible book value of $1.66 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of approximately $33.66 per share to new investors purchasing shares of Class A common stock in this offering and the concurrent private placement.

Dilution per share to new investors is determined by subtracting pro forma as adjusted net tangible book value per share after this offering from the initial public offering price per share paid by new investors. The following table illustrates this dilution (without giving effect to any exercise by the underwriters of their over-allotment option):

If the underwriters exercise their over-allotment option in full, the pro forma as adjusted net tangible book value after the offering and the concurrent private placement would be $2.72 per share, the increase in pro forma net tangible book value per share to existing stockholders would be $2.05 per share and the dilution per share to new investors would be $33.28 per share, in each case based on the initial public offering price of $36.00 per share.

The following table summarizes on the pro forma as adjusted basis described above, as of January 31, 2019, the differences between the number of shares of Class B common stock purchased from us by our existing stockholders and Class A common stock by new investors purchasing shares in this offering and the concurrent private placement, the total consideration paid to us in cash and the average price per share paid by existing stockholders for shares of Class B common stock issued prior to this offering and the price to be paid by new investors for shares of Class A common stock in this offering and the concurrent private placement. The calculation below is based on the initial public offering price of $36.00 per share, before deducting underwriting

50

discounts and commissions and estimated expenses related to the offering and the concurrent private placement payable by us.

Sales by the selling stockholders in this offering will reduce the number of shares held by existing stockholders to 232,741,029, or approximately 90.8% of the total shares of common stock outstanding after this offering and the concurrent private placement, and will increase the number of shares held by new investors (including the concurrent private placement investor) to 23,647,342, or approximately 9.2% of the total shares of common stock outstanding after this offering and the concurrent private placement.

The outstanding share information in the table above is based on 422,744 shares of our Class A common stock (including the conversion of convertible promissory notes) and 242,993,239 shares of our Class B common stock (including preferred stock on an as-converted basis and reclassified as Class B common stock) outstanding as of January 31, 2019 and excludes:

To the extent any outstanding options are exercised, there will be further dilution to new investors. If all of such outstanding options had been exercised as of January 31, 2019, the pro forma as adjusted net tangible book value per share after this offering and the concurrent private placement would be $2.24, and total dilution per share to new investors would be $33.76.

51

If the underwriters exercise their over-allotment option in full, our existing stockholders would own 89.7% and the investors purchasing shares of our Class A common stock in this offering and the concurrent private placement would own 10.3% of the total number of shares of our Class A common stock outstanding immediately after completion of this offering and the concurrent private placement.

Overview

Our mission is to make video communications frictionless.

We provide a video-first communications platform that delivers happiness and fundamentally changes how people interact. We connect people through frictionless video, voice, chat and content sharing and enable face-to-face video experiences for thousands of people in a single meeting across disparate devices and locations. Our cloud-native platform delivers reliable, high-quality video that is easy to use, manage and deploy, provides an attractive return on investment, is scalable and easily integrates with physical spaces and applications. We believe that rich and reliable communications lead to interactions that build greater empathy and trust. We strive to live up to the trust our customers place in us by delivering a communications solution that “just works.” Our goal is to make Zoom meetings better than in-person meetings.

The positive impact we have on our customers and hosts is reflected in our average customer Net Promoter Score (NPS), which was over 70 in 2018. NPS, which can range from a low of -100 to a high of +100, measures the willingness of customers to recommend a company’s products or services to others and is used as a proxy for gauging customers’ overall satisfaction with a company’s product or service and the customers’ loyalty to the brand. We believe our customer-first focus is a critical part of our DNA and built directly into our platform architecture, which dynamically processes and delivers reliable, high-quality video across devices. Our architecture can support tens of thousands of video participants in a single meeting. Our 13 co-located data centers located worldwide enable us to provide both high-quality and high-definition, real-time video to our customers even in low bandwidth environments.

Since our inception, our consistent focus on innovation has allowed us to achieve the following significant milestones:
