The aggregate market value of the voting and non-voting common equity held by non-affiliates of the registrant, based on the closing price of a share of the registrant’s Class A common stock on January 30, 2015 as reported by the New York Stock Exchange on such date was approximately $937.7 million. The registrant has elected to use January 30, 2015, which was the last business day of the registrant’s most recently completed fiscal year, as the calculation date because on July 31, 2014 (the last business day of the registrant’s mostly recently completed second fiscal quarter), the registrant was a privately-held company. Shares of the registrant’s Class A common stock and Class B common stock held by each executive officer, director and holder of 5% or more of the outstanding Class A common stock and Class B common stock have been excluded in that such persons may be deemed to be affiliates. This calculation does not reflect a determination that certain persons are affiliates of the registrant for any other purpose.

As of February 28, 2015 the number of shares of the registrant’s Class A common stock outstanding was 14,460,332 and the number of shares of the registrant’s Class B common stock outstanding was 105,328,377.

Portions of the registrant’s Definitive Proxy Statement relating to the Annual Meeting of Stockholders are incorporated by reference into Part III of this Annual Report on Form 10-K where indicated. Such Definitive Proxy Statement will be filed with the Securities and Exchange Commission within 120 days after the end of the registrant’s fiscal year ended January 31, 2015.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in the section titled “Risk Factors” and elsewhere in this Annual Report on Form 10-K. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Annual Report on Form 10-K may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Annual Report on Form 10-K to conform these statements to actual results or to changes in our expectations, except as required by law.

You should read this Annual Report on Form 10-K and the documents that we reference in this Annual Report on Form 10-K and have filed with the SEC as exhibits to this Annual Report on Form 10-K with the understanding that our actual future results, levels of activity, performance, and events and circumstances may be materially different from what we expect.

PART I

Item 1. BUSINESS

Overview

Box provides a cloud-based, mobile-optimized Enterprise Content Collaboration platform that enables organizations of all sizes to easily and securely manage their content from anywhere. Our platform enables users to collaborate on content both internally and externally, build workflows to power mission-critical processes and deploy compliance and security features that are valuable to most industries and essential in certain industries. We have built our platform to work across multiple file formats, application environments, operating systems and devices.

At our founding in 2005, we recognized that content is more accessible, useful and powerful when it is centrally stored, managed and shared. We have architected our Enterprise Content Collaboration platform from the ground up to be cloud-based and mobile-optimized to meet the evolving demands of today’s information worker. Cloud-based Enterprise Content Collaboration is especially powerful because it enables users to access and collaborate on centralized content from anywhere and allows organizations to access new features and apply policies and controls across all users and content simultaneously. Our solution is especially well-suited to support globally distributed workers with multiple devices and can support deployments ranging in size from one user to over a hundred thousand users.

Our go-to-market strategy combines end-user-driven bottoms-up adoption with top-down sales efforts. We offer individuals a free basic version of Box to provide them with a first-hand experience of the simplicity and effectiveness of our service. Our solution often spreads virally within and across organizations, as users adopt Box and invite new users to collaborate. Frequently, an organization will purchase Box for one use case and later expand its deployment to other use cases and larger groups of employees leading to deeper engagement with our service.

We also deliver industry-specific solutions that target specific business needs with a combination of technology, services and marketing programs aimed at prospective buyers. Where relevant, we also facilitate compliance with industry-specific regulations to ensure companies can use Box in accordance with legal requirements. These industry solutions are aimed to speed the deployment and time to value for customers in industries such as healthcare and life sciences, financial services, legal services, media and entertainment, retail, education, energy and government.

We are building a rich ecosystem around Box. Our platform integrates with the applications of our technology partners, including salesforce.com, NetSuite and others, giving our users full access to Box without leaving partner applications. In addition, third-party developers can rapidly build, update and provision new applications that leverage and extend the core functionality of our service, increasingly with a focus on specific industries and vertical market use cases. To date, tens of thousands of third-party developers have leveraged our platform as the secure content layer for their applications, including developers that are part of our Box OneCloud ecosystem, which provides users with access to more than 1,300 iOS and Android third-party applications.

The Box Solution

We deliver applications (web and mobile), a platform for custom development and a series of industry-specific solutions. Our features and functionality include the following:

Customers

Our user base includes over 34 million registered users across more than 280,000 organizations. We define a registered user as a Box account that has been provisioned to a unique user ID. As of January 31, 2015, approximately 90% of our registered users are non-paying users who have independently registered for accounts and approximately 10% of our registered users are paying users who register as part of a larger enterprise or business account or by using a personal account.

We currently have over 45,000 paying organizations, and our solution is offered in 22 languages. We define paying organizations as separate and distinct buying entities, such as a company, an educational or government institution, or a distinct business unit of a large corporation, that have entered into a subscription agreement with us to utilize our services. Organizations typically purchase our solution in the following ways: (i) employees in one or more small groups within the organization may individually purchase our service; (ii) organizations may purchase IT sponsored, enterprise-level agreements with deployments for specific, targeted use cases ranging from tens to thousands of user seats; or (iii) organizations may purchase IT-sponsored, enterprise-level agreements where the number of user seats sold is intended to accommodate and enable nearly all information workers within the organization in whatever use cases they desire to adopt over the term of the subscription.

For the 12 months ended January 31, 2015, 59% of our orders for subscription services were from new enterprise customers and expansion within existing enterprise customers. We consider enterprise customers to be organizations with at least 1,000 employees, as such organizations are the focus of our Enterprise Accounts sales team. Our current customer base spans numerous industries including healthcare and life sciences, financial services, legal services, media and entertainment, retail, education, energy and government. No individual customer represented more than 10% of our revenues in the year ended January 31, 2015.

We have developed several programs designed to provide customers with service options to quickly get them up and running and enhance their usage of our platform. These services include 24x7 support; a professional services ecosystem that consists of our Box Consulting team and system integrators that help customers implement simple use cases as well as more complex platform and content management oriented use cases, a Customer Success Management group to assist customers in production; and an online help center with self-service training materials, best practice guides and product documentation.

Sales and Marketing

We offer our solution to our customers as a subscription-based service, with subscription fees based on the requirements of our customers, including the number of users and functionality deployed. The majority of our customers subscribe to our service through one-year contracts, although we also offer our services for terms ranging between one month to three years or more. We typically invoice our customers at the beginning of the term, in multiyear, annual, quarterly or monthly installments. We recognize revenue ratably over the term of the subscription period.

We make it easy for users and organizations to subscribe to paid versions of our service on our self-service web portal. We also employ a direct sales team to offer a higher touch experience. Our sales team is composed of inside sales, outbound sales and field sales personnel who are generally organized by account size and geography, and/or major industry focus. We also have a rich ecosystem of channel partners who expand our reach to both large and small enterprises.

We generate customer leads, accelerate sales opportunities and build brand awareness through our marketing programs and through our strategic relationships. Our marketing programs target senior IT leaders, technology professionals and senior line of business leaders.

As a core part of our strategy, we have developed an ecosystem of partners to both broaden and complement our application offerings and to provide a broad array of services that lie outside of Box’s areas of focus. These relationships include software and technology partners, consulting and implementation services providers that enable Box to address a broader set of use cases for our customers.

Research and Development

Our ability to compete depends in large part on our continuous commitment to product development and our ability to rapidly introduce new applications, technologies, features and functionality. In simple conceptual form, we provide a product that allows companies to securely share files. In practice, we develop and maintain a set of sophisticated software services (e.g., search, share, secure, convert/view, log, etc.) around corporate content. These services, which comprise the Box Platform, are used to develop our own applications (e.g., sync, web, native mobile) and also support the development of third party applications.

Our product development organization is responsible for the specification, design, development and testing of our platform and applications. We focus our efforts on improving the security, reliability, performance and flexibility of the services in our platform. And we continually improve our applications so that they help users and teams become more productive in their day-to-day work.

Research and development expenses were $66.4 million, $46.0 million and $29.0 million for the years ended January 31, 2015, 2014 and 2013, respectively.

Competition

The Enterprise Content Collaboration market is large, highly competitive and highly fragmented. It is subject to rapidly evolving technology, shifting customer needs and frequent introductions of new products and services. Outside of the Enterprise Content Collaboration market, we compete against several categories of technology providers: vendors whose core competency is simple file sync and share, which can be deployed on premise, hybrid, or via a SaaS delivery model; real-time collaboration vendors whose focus is on real-time voice, video and text communication in the enterprise; social collaboration vendors who focus on the conversations that occur between teams; traditional Enterprise Content Management (ECM) vendors who deploy on premise and offer deep records management, business process workflow, and archival capabilities; and newer mobile enterprise vendors who are beginning to enter the content collaboration market, are adding adjacent content capabilities onto an existing product, or serve a particular business or industry use case. Our current primary competitors include but are not limited to:

Table of Contents

We may face future competition in our markets from other large, established companies, as well as from smaller specialized companies. In addition, we expect continued consolidation in our industry which could adversely alter the competitive dynamics of our markets including both pricing and the ability for us to compete successfully for customers.

The principal competitive factors in our market include:

We believe that we compete favorably on the basis of these factors. Our ability to remain competitive will depend to a great extent upon our ongoing performance in the areas of product development, core technical innovation, platform and partner ecosystem and customer support. In addition, many of our competitors, particularly the large software companies named above, may have greater name recognition, longer operating histories, significantly greater resources and established relationships with our partners and customers which can give them advantageous positioning for their products despite other competitive merits of respective product features and functionality. Some competitors may be able to devote greater resources to the development, promotion and sale of their products than we can to ours, which could allow them to respond more quickly than we can to new technologies and changes in customer needs.

Intellectual Property

We rely on a combination of trade secrets, patents, copyrights and trademarks, as well as contractual protections, to establish and protect our intellectual property rights. As of January 31, 2015, we had nine issued U.S. patents and 11 issued Great Britain patents that directly relate to our technology that expire between 2028 and 2033, and we had 87 pending patent applications in the U.S. and 44 pending patent applications internationally. We intend to pursue additional patent protection to the extent that we believe it would be beneficial and cost effective.

Table of Contents

We require our employees, contractors, consultants and other third parties to enter into confidentiality and proprietary rights agreements and control access to software, documentation and other proprietary information. Although we rely on intellectual property rights, including trade secrets, patents, copyrights and trademarks, as well as contractual protections to establish and protect our proprietary rights, we believe that factors such as the technological and creative skills of our personnel, creation of new modules, features and functionality, and frequent enhancements to our applications are more essential to establishing and maintaining our technology leadership position.

Despite our efforts to protect our proprietary technology and our intellectual property rights, unauthorized parties may attempt to copy or obtain and use our technology to develop applications with the same functionality as our application. Policing unauthorized use of our technology and intellectual property rights is difficult.

We expect that software and other applications in our industry may be subject to third-party infringement claims as the number of competitors grows and the functionality of applications in different industry segments overlaps. Any of these third parties might make a claim of infringement against us at any time.

Employees

As of January 31, 2015, we had 1,158 employees. None of our employees are represented by a labor union. We have not experienced any work stoppages, and we consider our relations with our employees to be very good.

Item 1A. RISK FACTORS

Investing in our Class A common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before making a decision to invest in our Class A common stock. If any of the risks actually occur, our business, financial condition, operating results and prospects could be materially and adversely affected. In that event, the market price of our Class A common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business and Our Industry

We have a history of cumulative losses, and we do not expect to be profitable for the foreseeable future.

We have incurred significant losses in each period since our inception in 2005. We incurred net losses of $168.2 million in our fiscal year ended January 31, 2015, $168.6 million in our fiscal year ended January 31, 2014, and $112.6 million in our fiscal year ended January 31, 2013. As of January 31, 2015, we had an accumulated deficit of $529.4 million. These losses and accumulated deficit reflect the substantial investments we made to acquire new customers and develop our services. We intend to continue scaling our business to increase our number of users and paying organizations and to meet the increasingly complex needs of our customers. We have invested, and expect to continue to invest, in our sales and marketing organizations to sell our services around the world and in our development organization to deliver additional features and capabilities of our cloud services to address our customers’ evolving needs. We also expect to continue to make significant investments in our datacenter infrastructure and in our professional service organization as we focus on customer success. As a result of our continuing investments to scale our business in each of these areas, we do not expect to be profitable for the foreseeable future. Furthermore, to the extent we are successful in increasing our customer base, we will also incur increased losses due to upfront costs associated with acquiring new customers, particularly as a result of the limited free trial version of our service, and the nature of subscription revenue which is generally recognized ratably over the term of the subscription period, which is typically one year, although we also offer our services for terms ranging between one month to three years or more. We cannot assure you that we will achieve profitability in the future or that, if we do become profitable, we will sustain profitability.

We have a limited operating history, which makes it difficult to predict our future operating results.

We were incorporated and introduced our first service in 2005. As a result of our limited operating history, our ability to accurately forecast our future operating results is limited and subject to a number of uncertainties. We have encountered, and will continue to 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 due to changes in our markets, or if we do not address these risks and uncertainties successfully, our operating and financial results could differ materially from our expectations, and our business could suffer.

The market in which we participate is intensely competitive, and if we do not compete effectively, our operating results could be harmed.

The market for cloud-based Enterprise Content Collaboration services is fragmented, rapidly evolving and highly competitive, with relatively low barriers to entry for certain applications and services. Many of our competitors and potential competitors are larger and have greater name recognition, much longer operating histories, larger marketing budgets and significantly greater resources than we do. Our competitors include, but are not limited to, Microsoft, Google, Dropbox, Citrix and EMC. With the introduction of new technologies and market entrants, we expect competition to continue to intensify in the future. If we fail to compete effectively, our business will be harmed. Some of our principal competitors offer their products or services at a lower price, which has resulted in pricing pressures on our business. If we are unable to achieve our target pricing levels, our

10

Table of Contents

operating results would be negatively impacted. In addition, pricing pressures and increased competition generally could result in reduced sales, lower margins, losses or the failure of our services to achieve or maintain widespread market acceptance, any of which could harm our business.

Many of our competitors are able to devote greater resources to the development, promotion and sale of their products or services. In addition, many of our competitors have established marketing relationships and major distribution agreements with channel partners, consultants, system integrators and resellers. Moreover, many software vendors could bundle products or offer them at lower prices as part of a broader product sale or enterprise license arrangement. Some competitors may offer products or services that address one or a number of business execution functions at lower prices or with greater depth than our services. As a result, our competitors may be able to respond more quickly and effectively to new or changing opportunities, technologies, standards or customer requirements. Furthermore, some potential customers, particularly large enterprises, may elect to develop their own internal solutions. For all of these reasons, we may not be able to compete successfully against our current and future competitors.

If the cloud-based Enterprise Content Collaboration market develops more slowly than we expect or declines, our business could be adversely affected.

The cloud-based Enterprise Content Collaboration market is not as mature as the market for on-premise enterprise software, and it is uncertain whether a cloud-based service like ours will achieve and sustain high levels of customer demand and market acceptance. Because we derive, and expect to continue to derive, substantially all of our revenue and cash flows from sales of our cloud-based Enterprise Content Collaboration solution, our success will depend to a substantial extent on the widespread adoption of cloud computing in general and of cloud-based content collaboration services in particular. Many organizations have invested substantial personnel and financial resources to integrate traditional enterprise software into their organizations and, therefore, may be reluctant or unwilling to migrate to a cloud-based model for storing, accessing, sharing and managing their content. It is difficult to predict customer adoption rates and demand for our services, the future growth rate and size of the cloud computing market or the entry of competitive services. The expansion of a cloud-based Enterprise Content Collaboration market depends on a number of factors, including the cost, performance and perceived value associated with cloud computing, as well as the ability of companies that provide cloud-based services to address security and privacy concerns. If we or other providers of cloud-based services experience security incidents, loss of customer data, disruptions in delivery or other problems, the market for cloud-based services as a whole, including our services, may be negatively affected. If cloud-based services do not achieve widespread adoption, or there is a reduction in demand for cloud-based services caused by a lack of customer acceptance, technological challenges, weakening economic conditions, security or privacy concerns, competing technologies and products, decreases in corporate spending or otherwise, it could result in decreased revenue, harm our growth rates, and adversely affect our business and operating results.

We have experienced rapid growth in recent periods. If we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service or adequately address competitive challenges.

We have recently experienced a period of rapid growth in our operations and employee headcount. In particular, we grew from 972 employees as of January 31, 2014 to 1,158 employees as of January 31, 2015, and have also significantly increased the size of our customer base. You should not consider our recent growth as indicative of our future performance. However, we anticipate that we will significantly expand our operations and employee headcount in the near term, including internationally. This growth has placed, and future growth will place, a significant strain on our management, administrative, operational and financial infrastructure. Our success will depend in part on our ability to manage this growth effectively. To manage the expected growth of our operations and personnel, we will need to continue to improve our operational, financial and management controls, and our reporting systems and procedures. Failure to effectively manage growth could result in

11

Table of Contents

difficulty or delays in deploying customers, declines in quality or customer satisfaction, increases in costs, difficulties in introducing new features or other operational difficulties. Any of these difficulties could adversely impact our business performance and operating results.

Our business depends substantially on customers renewing their subscriptions with us and expanding their use of our services. Any decline in our customer renewals or failure to convince our customers to broaden their use of our services would harm our future operating results.

In order for us to maintain or improve our operating results, it is important that our customers renew their subscriptions with us when the existing subscription term expires. Our customers have no obligation to renew their subscriptions upon expiration, and we cannot assure you that customers will renew subscriptions at the same or higher level of service, if at all. Although our retention rate has historically been high, some of our customers have elected not to renew their subscriptions with us.

Our retention rate may decline or fluctuate as a result of a number of factors, including our customers’ satisfaction or dissatisfaction with our services, the effectiveness of our customer support services, our pricing, the prices of competing products or services, mergers and acquisitions affecting our customer base, the effects of global economic conditions or reductions in our customers’ spending levels. If our customers do not renew their subscriptions, purchase fewer seats or renew on less favorable terms, our revenue may decline, and we may not realize improved operating results from our customer base.

In addition, the growth of our business depends in part on our customers expanding their use of our services. The use of our cloud-based Enterprise Content Collaboration platform often expands within an organization as new users are added or as additional services are purchased by or for other departments within an organization. Further, as we have introduced new services throughout our operating history, our existing customers have constituted a significant portion of the users of such services. If we are unable to encourage our customers to broaden their use of our services, our operating results may be adversely affected.

If we are not able to provide successful enhancements, new features and modifications to our services, our business could be adversely affected.

Our industry is marked by rapid technological developments and new and enhanced applications and services. If we are unable to provide enhancements and new features for our existing services or new services that achieve market acceptance or that keep pace with rapid technological developments, our business could be adversely affected. For example, we have recently introduced Box for Industries, a set of enterprise content collaboration solutions aimed at transforming how businesses across verticals work with information. These solutions are underpinned by Box Workflow, a new technology that powers intelligent business processes on the Box platform. The success of enhancements, new features and services depends on several factors, including the timely completion, introduction and market acceptance of such enhancements, features or services. Failure in this regard may significantly impair our revenue growth. In addition, because our services are designed to operate on a variety of systems, we will need to continuously modify and enhance our services to keep pace with changes in internet-related hardware, mobile operating systems such as iOS and Android, and other software, communication, browser and database technologies. We may not be successful in either developing these modifications and enhancements or in bringing them to market in a timely fashion. Furthermore, modifications to existing platforms or technologies will increase our research and development expenses. Any failure of our services to operate effectively with future network platforms and technologies could reduce the demand for our services, result in customer dissatisfaction and adversely affect our business.

Actual or perceived security vulnerabilities in our services or any breaches of our security controls and unauthorized access to a customer’s data could harm our business and operating results.

The services we offer involve the storage of large amounts of our customers’ sensitive and proprietary information. Cyber attacks and other malicious internet-based activity continue to increase in frequency and in

12

Table of Contents

magnitude generally, and cloud-based content collaboration services have been targeted in the past. As we increase our customer base and our brand becomes more widely known and recognized, we may become more of a target for these malicious third parties. If our security measures are breached as a result of third-party action, employee negligence and/or error, malfeasance, product defects or otherwise, and this results in the disruption of the confidentiality, integrity or availability of our customers’ data, we could incur significant liability to our customers and to individuals or organizations whose information was being stored by our customers, and our business may suffer and our reputation may be damaged. Techniques used to obtain unauthorized access to, or to sabotage, systems or networks, change frequently and generally are not recognized until launched against a target. Therefore, we may be unable to anticipate these techniques, react in a timely manner, or implement adequate preventive measures. In addition, our customer contracts often include (i) specific obligations that we maintain the availability of the customer’s data through our service and that we secure customer content against unauthorized access or loss, and (ii) indemnity provisions whereby we indemnify our customers for third-party claims asserted against them that result from our failure to maintain the availability of their content or securing the same from unauthorized access or loss. While our customer contracts contain limitations on our liability in connection with these obligations and indemnities, if an actual or perceived security breach occurs, the market perception of the effectiveness of our security measures could be harmed, we could be subject to indemnity or damage claims in certain customer contracts, and we could lose future sales and customers, any of which could harm our business and operating results. Furthermore, while our errors and omissions insurance policies include liability coverage for these matters, if we experienced a widespread security breach that impacted a significant number of our customers for whom we have these indemnity obligations, we could be subject to indemnity claims that exceed such coverage.

As a substantial portion of our sales efforts are increasingly targeted at enterprise customers, our sales cycle may become increasingly lengthier and more expensive, we may encounter still greater pricing pressure and implementation and customization challenges, and we may have to delay more revenue recognition for more complicated transactions, all of which could harm our business and operating results.

As a substantial portion of our sales efforts are increasingly targeted at enterprise customers, we face greater costs, longer sales cycles and less predictability in the completion of some of our sales. In this market segment, the customer’s decision to use our services may be an enterprise-wide decision, in which case these types of sales require us to provide greater levels of customer education regarding the uses and benefits of our services, as well as education regarding security, privacy, and data protection laws and regulations, especially for those customers in more heavily regulated industries or those with significant international operations. In addition, larger enterprises may demand more customization, integration and support services, and features. As a result of these factors, these sales opportunities may require us to devote greater sales support and professional services resources to individual customers, which could increase our costs and sales cycle and divert our own sales and professional services resources to a smaller number of larger customers. Meanwhile, this would potentially require us to delay revenue recognition on some of these transactions until the technical or implementation requirements have been met. Professional services may also be performed by a third party or a combination of our own staff and a third party. Our strategy is to work with third parties to increase the breadth of capability and depth of capacity for delivery of these services to our customers. If a customer is not satisfied with the quality or interoperability of our services with their own IT environment, we could incur additional costs to address the situation, which could adversely affect our margins. Moreover, any customer dissatisfaction with our services could damage our ability to encourage broader adoption of our services by that customer. In addition, any negative publicity resulting from such situations, regardless of its accuracy, may further damage our business by affecting our ability to compete for new business with current and prospective customers.

Privacy concerns and laws or other domestic or foreign regulations may reduce the effectiveness of our services and harm our business.

Users can use our services to store personal or identifying information. However, federal, state and foreign government bodies and agencies have adopted or are considering adopting laws and regulations regarding the

13

Table of Contents

collection, use and disclosure of personal information obtained from consumers and other individuals. The costs of compliance with, and other burdens imposed by, such laws and regulations that are applicable to our business or the businesses of our customers may limit the use and adoption of our services and reduce overall demand for them.

In addition, foreign data protection, privacy and other laws and regulations are often more restrictive than those in the United States. For example, a revision to the 1995 European Union Data Protection Directive is currently being considered by European legislative bodies that may include more stringent operational requirements for data processors and significant penalties for non-compliance. Similarly, there have been a number of recent legislative proposals in the United States, at both the federal and state level, that would impose new obligations in areas such as privacy and liability for copyright infringement by third parties. These existing and proposed laws and regulations can be costly to comply with and can delay or impede the development of new products, result in negative publicity, increase our operating costs, require significant management time and attention, and subject us to claims or other remedies, including fines or demands that we modify or cease existing business practices.

These U.S. federal and state and foreign laws and regulations, which can be enforced by private parties or governmental entities, are constantly evolving and can be subject to significant change. A number of proposals are pending before federal, state and foreign legislative and regulatory bodies that could affect our business. For example, the European Commission is currently considering a data protection regulation that may include operational requirements for companies that receive personal data that are different than those currently in place in the European Union, and that may also include significant penalties for non-compliance. In addition, some countries are considering legislation requiring local storage and processing of data that could increase the cost and complexity of delivering our services.

Furthermore, government agencies may seek to access sensitive information that our users upload to Box, or restrict users’ access to Box. Laws and regulations relating to government access and restrictions are evolving, and compliance with such laws and regulations could limit adoption of our services by users and create burdens on our business. Moreover, regulatory investigations into our compliance with privacy-related laws and regulations could increase our costs and divert management attention.

If we are not able to satisfy data protection, security, privacy, and other government- and industry-specific requirements, our growth could be harmed.

There are a number of data protection, security, privacy and other government- and industry-specific requirements, including those that require companies to notify individuals of data security incidents involving certain types of personal data. Security compromises experienced by our competitors, by our customers or by us may lead to public disclosures, which could harm our reputation, erode customer confidence in the effectiveness of our security measures, negatively impact our ability to attract new customers, or cause existing customers to elect not to renew their agreements with us. In addition, some of the industries we serve have industry-specific requirements relating to compliance with certain security and regulatory standards, such as those required by the HIPAA and the HITECH Act. As we expand into new verticals and regions, we will need to comply with these and other new requirements. If we cannot comply or if we incur a violation in one or more of these requirements, our growth could be adversely impacted, and we could incur significant liability.

Because we recognize revenue from subscriptions for our services over the term of the subscription, downturns or upturns in new business may not be immediately reflected in our operating results.

We generally recognize revenue from customers ratably over the terms of their subscription agreements, which are typically one year, although we also offer our services for terms ranging between one month to three years or more. As a result, most of the revenue we report in each quarter is the result of subscription agreements entered into during previous quarters. Consequently, a decline in new or renewed subscriptions in any one

14

Table of Contents

quarter may not be reflected in our revenue results for that quarter. However, any such decline will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our services, and potential changes in our retention rate may not be fully reflected in our operating results until future periods. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers must be recognized over the applicable subscription term.

Our platform must integrate with a variety of operating systems and software applications that are developed by others, and if we are unable to ensure that our solutions interoperate with such systems and applications, our service may become less competitive, and our operating results may be harmed.

We offer our services across a variety of operating systems and through the internet. We are dependent on the interoperability of our platform with third-party mobile devices, desktop and mobile operating systems, as well as web browsers that we do not control. Any changes in such systems, devices or web browsers that degrade the functionality of our services or give preferential treatment to competitive services could adversely affect usage of our services. In order to deliver high quality services, it is important that they work well with a range of operating systems, networks, devices, web browsers and standards that we do not control. In addition, because a substantial number of our users access our services through mobile devices, we are particularly dependent on the interoperability of our services with mobile devices and operating systems. We may not be successful in developing relationships with key participants in the mobile industry or in developing services that operate effectively with these operating systems, networks, devices, web browsers and standards. In the event that it is difficult for our users to access and use our services, our user growth may be harmed, and our business and operating results could be adversely affected.

We cannot accurately predict new subscription or expansion rates and the impact these rates may have on our future revenue and operating results.

In order for us to improve our operating results and continue to grow our business, it is important that we continue to attract new customers and expand deployment of our solution with existing customers. To the extent we are successful in increasing our customer base, we could incur increased losses because costs associated with new customers are generally incurred up front, while revenue is recognized ratably over the term of our subscription services. Alternatively, to the extent we are unsuccessful in increasing our customer base, we could also incur increased losses as costs associated with marketing programs and new products intended to attract new customers would not be offset by incremental revenue and cash flow. Furthermore, if our customers do not expand their deployment of our services, our revenue may grow more slowly than we expect. All of these factors can negatively impact our future revenue and operating results.

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

Our quarterly operating results, including the levels of our revenue, gross margin, profitability, cash flow and deferred revenue, may vary significantly in the future, and period-to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly financial results 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. Fluctuations in quarterly results may negatively impact the value of our Class A common stock. Factors that may cause fluctuations in our quarterly financial results include, but are not limited to:

One of our marketing strategies is to offer a limited free version of our service, and we may not be able to realize the benefits of this strategy.

We offer a limited version of our service to users free of charge in order to promote additional usage, brand and product awareness, and adoption. Some users never convert from a free version to a paid version of our service. Our marketing strategy also depends in part on persuading users who use the free version of our service to convince decision-makers to purchase and deploy our service within their organization. To the extent that these users do not become, or lead others to become, paying customers, we will not realize the intended benefits of this marketing strategy, and our ability to grow our business and revenue may be harmed.

If we fail to effectively manage our technical operations infrastructure, our customers may experience service outages and delays in the further deployment of our services, which may adversely affect our business.

We have experienced significant growth in the number of users and the amount of data that our operations infrastructure supports. We seek to maintain sufficient excess capacity in our operations infrastructure to meet the needs of all of our customers. We also seek to maintain excess capacity to facilitate the rapid provisioning of new customer deployments and the expansion of existing customer deployments. In addition, we need to properly manage our technological operations infrastructure in order to support version control, changes in hardware and software parameters and the evolution of our services. However, the provision of new hosting infrastructure requires significant lead-time. We have experienced, and may in the future experience, website disruptions, outages and other performance problems. These problems may be caused by a variety of factors, including infrastructure changes, human or software errors, viruses, security attacks, fraud, spikes in customer usage, primary and redundant hardware or connectivity failures, dependent service provider failures 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, which may harm our reputation and operating results. Furthermore, if we do not accurately predict our infrastructure requirements, our existing customers may experience service outages that may subject us to financial penalties, financial liabilities and customer losses. If our operations infrastructure fails to keep pace with increased sales, customers may experience delays as we seek to obtain additional capacity, which could adversely affect our reputation and our revenue.

Interruptions or delays in service from our third-party datacenter hosting facilities could impair the delivery of our services and harm our business.

We currently store our customers’ information within two third-party datacenter hosting facilities located in Northern California. As part of our current disaster recovery arrangements, our production environment and all of our customers’ data is currently replicated in near real time in a facility located in Las Vegas, Nevada. In addition, all of our customers’ data is further replicated on a third-party storage platform located on the East Coast. These facilities are located in areas prone to earthquakes and are also vulnerable to damage or interruption from floods, fires, power loss, telecommunications failures and similar events. They may also be subject to break-ins, sabotage, intentional acts of vandalism and similar misconduct. Any damage to, or failure of, our systems generally could result in interruptions in our service. Interruptions in our service may reduce our revenue, cause us to issue credits or pay penalties, cause customers to terminate their subscriptions and adversely affect our renewal rate and our ability to attract new customers. Our business will also be harmed if our customers and potential customers believe our service is unreliable. Despite precautions taken at these facilities, the occurrence of a natural disaster, an act of terrorism, a decision to close the facilities without adequate notice or other unanticipated problems at these facilities could result in lengthy interruptions in our service. Even with the disaster recovery arrangements, our service could be interrupted. As we continue to add datacenters and add capacity in our existing datacenters, we may move or transfer our data and our customers’ data. Despite precautions taken during this process, any unsuccessful data transfers may impair the delivery of our service. Further, as we continue to grow and scale our business to meet the needs of our customers, additional burdens may be placed on our hosting facilities. In particular, a rapid expansion of our business could cause our network or systems to fail.

If we overestimate or underestimate our data center capacity requirements, our operating results could be adversely affected.

Only a small percentage of our customers that are organizations currently use our service as a way to organize all of their internal files. In particular, larger organizations and enterprises typically use our service to connect people and their most important information so that they are able to get work done more efficiently. However, over time, we may experience an increase in customers that look to Box as their complete content storage solution. The costs associated with leasing and maintaining our data centers already constitute a significant portion of our capital and operating expenses. We continuously evaluate our short- and long-term data center capacity requirements to ensure adequate capacity for new and existing customers while minimizing unnecessary excess capacity costs. If we overestimate the demand for our cloud-based storage service and therefore secure excess data center capacity, our operating margins could be reduced. If we underestimate our data center capacity requirements, we may not be able to service the expanding needs of new and existing customers and may be required to limit new customer acquisition, which would impair our revenue growth. Furthermore, regardless of our ability to appropriately manage our data center capacity requirements, an increase in the number of organizations, in particular large businesses and enterprises, that use our service as a larger component of their content storage requirements could result in lower gross and operating margins or otherwise have an adverse impact on our financial condition and operating results.

We depend on highly skilled personnel to grow and operate our business, and if we are unable to hire, retain and motivate our personnel, we may not be able to grow effectively.

Our future success will depend upon our continued ability to identify, hire, develop, motivate and retain highly skilled personnel, including senior management, engineers, designers, product managers, sales representatives, and customer support representatives. Our ability to execute efficiently is dependent upon contributions from our employees, including our senior management team and, in particular, Aaron Levie, our co-founder, Chairman and Chief Executive Officer. In addition, occasionally, there may be changes in our senior management team that may be disruptive to our business. If our senior management team, including any new hires that we may make, fails to work together effectively and to execute on our plans and strategies on a timely basis, our business could be harmed.

Table of Contents

Our growth strategy also depends on our ability to expand our organization with highly skilled personnel. Identifying, recruiting, training and integrating qualified individuals will require significant time, expense and attention. In addition to hiring new employees, we must continue to focus on retaining our best employees. Many of our employees may be able to receive significant proceeds from sales of our equity in the public markets after the expiration of the lock-up period related to our initial public offering, which may reduce their motivation to continue to work for us. Competition for highly skilled personnel is intense, particularly in the San Francisco Bay Area, where our headquarters are located. We may need to invest significant amounts of cash and equity to attract and retain new employees, and we may never realize returns on these investments. If we are not able to effectively add and retain employees, our ability to achieve our strategic objectives will be adversely impacted, and our business will be harmed.

We may be sued by third parties for alleged infringement of their proprietary rights.

There is considerable patent and other intellectual property development activity in our industry. Our success depends on our not infringing upon the valid intellectual property rights of others. Our competitors, as well as a number of other entities, including non-practicing entities, and individuals, may own or claim to own intellectual property relating to our industry.

For example, on June 5, 2013, Open Text S.A. (Open Text) filed a lawsuit against us in U.S. District Court, Eastern District of Virginia, alleging that our core cloud software and Box Edit application directly and indirectly infringe 12 patents in three patent families that Open Text acquired through its acquisition of various companies. Open Text sought preliminary and permanent injunctions against infringement, treble damages, and attorneys’ fees. On February 13, 2015, a jury returned a verdict for Open Text in the amount of $4.9 million, finding that certain of the Open Text patents were infringed by our Box Edit feature and our Box Android application. Open Text has identified its intention to file appeals.

We intend to continue to defend the lawsuit vigorously through the appellate process. See Item 3. “Legal Proceedings” for additional information related to this litigation. Any adverse outcomes, licenses, settlements or unfavorable jury verdicts could have an adverse affect on both our financial results and financial position. Further, regardless of who prevails, intellectual property cases can be costly and time-consuming, divert the attention of our management and key personnel from our business operations and dissuade potential customers from purchasing our solution, which would also materially harm our business. During the course of litigation, we anticipate announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of our common stock may decline.

From time to time, certain other third parties have claimed that we are infringing upon their intellectual property rights, and we may be found to be infringing upon such rights. In addition, we cannot assure you that actions by other third parties alleging infringement by us of third-party patents will not be asserted or prosecuted against us. In the future, others may claim that our services and underlying technology infringe or violate their intellectual property rights. However, we may be unaware of the intellectual property rights that others may claim cover some or all of our technology or services. Any claims or litigation could cause us to incur significant expenses and, if successfully asserted against us, could require that we pay substantial damages or ongoing royalty payments, prevent us from offering our services, or require that we comply with other unfavorable terms. We may also be obligated to indemnify our customers or business partners or pay substantial settlement costs, including royalty payments, in connection with any such claim or litigation and to obtain licenses, modify services, or refund fees, which could be costly. Even if we were to prevail in such a dispute, any litigation regarding our intellectual property could be costly and time consuming and divert the attention of our management and key personnel from our business operations.

Any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand.

Our success and ability to compete depend in part on our intellectual property. As of January 31, 2015, we had nine issued U.S. patents, eleven issued Great Britain patents, and 87 pending patent applications in the U.S. and 44 pending patent applications internationally. We primarily rely on copyright, trade secret and trademark laws, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to protect our intellectual property rights. However, the steps we take to protect our intellectual property rights may be inadequate. We may not be able to obtain any further patents, and our pending applications may not result in the issuance of patents. We have issued patents and pending patent applications outside the U.S., and we may have to expend significant resources to obtain additional patents as we expand our international operations.

In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Accordingly, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Our failure to secure, protect and enforce our intellectual property rights could materially adversely affect our brand and adversely impact our business.

We rely on third parties for certain financial and operational services essential to our ability to manage our business. A failure or disruption in these services could materially and adversely affect our ability to manage our business effectively.

We rely on third parties for certain essential financial and operational services. Traditionally, the vast majority of these services have been provided by large enterprise software vendors who license their software to customers. However, we receive many of these services on a subscription basis from various software-as-a-service companies that are smaller and have shorter operating histories than traditional software vendors. Moreover, these vendors provide their services to us via a cloud-based model instead of software that is installed on our premises. As a result, we depend upon these vendors providing us with services that are always available and are free of errors or defects that could cause disruptions in our business processes, which would adversely affect our ability to operate and manage our operations.

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

Certain of our services are subject to export controls, including the U.S. Department of Commerce’s Export Administration Regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. The provision of our products and services must comply with these laws. The U.S. export control laws and U.S. economic sanctions laws include 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 encryption items. In addition, various countries regulate the import of certain encryption technology, including through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our services or could limit our customers’ ability to implement our services in those countries.

Although we take precautions to prevent our services from being provided in violation of such laws, our solutions may have been in the past, and could in the future be, provided inadvertently in violation of such laws, despite the precautions we take. If we fail to comply with these laws, we and our employees could be subject to

19

Table of Contents

civil or criminal penalties, including the possible loss of export privileges, monetary penalties, and, in extreme cases, imprisonment of responsible employees for knowing and willful violations of these laws. We may also be adversely affected through penalties, reputational harm, loss of access to certain markets, or otherwise.

Changes in our services, or changes in export, sanctions and import laws, may delay the introduction and sale of our services in international markets, prevent our customers with international operations from deploying our services or, in some cases, prevent the export or import of our services to certain countries, governments, persons or entities altogether. 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 services, or in our decreased ability to export or sell our services to existing or potential customers with international operations. Any decreased use of our services or limitation on our ability to export or sell our services would likely adversely affect our business, financial condition and operating results.

We focus on product innovation and user engagement rather than short-term operating results.

We focus heavily on developing and launching new and innovative products and features, as well as on improving the user experience for our services. We also focus on growing the number of Box users and paying organizations through direct field sales, direct inside sales, indirect channel sales and through word-of-mouth by individual users, some of whom use our services at no cost. We prioritize innovation and the experience for users on our platform, as well as the growth of our user base, over short-term operating results. We frequently make product and service decisions that may reduce our short-term operating results if we believe that the decisions are consistent with our goals to improve the user experience and to develop innovative features that we feel our users desire. These decisions may not be consistent with the short-term expectations of investors and may not produce the long-term benefits that we expect.

We provide service level commitments under our subscription agreements. If we fail to meet these contractual commitments, we could be obligated to provide credits or refunds for prepaid amounts related to unused subscription services or face subscription terminations, which could adversely affect our revenue. Furthermore, any failure in our delivery of high-quality customer support services may adversely affect our relationships with our customers and our financial results.

Our subscription agreements with customers provide certain service level commitments. If we are unable to meet the stated service level commitments or suffer periods of downtime that exceed the periods allowed under our customer agreements, we may be obligated to provide these customers with service credits which could significantly impact our revenue in the period in which the downtime occurs and the credits could be due. We could also face subscription terminations, which could significantly impact both our current and future revenue. Any extended service outages could also adversely affect our reputation, which would also impact our future revenue and operating results.

Our customers depend on our customer success organization to resolve technical issues relating to our services. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support services. Increased customer demand for these services, without corresponding revenue, could increase costs and adversely affect our operating results. In addition, our sales process is highly dependent on the ease of use of our services, on our reputation and on positive recommendations from our existing customers. Any failure to maintain high-quality customer support, or a market perception that we do not maintain high-quality support, could adversely affect our reputation and our ability to sell our services to existing and prospective customers.

20

Table of Contents

If our services fail to perform properly or if we are unable to scale our services to meet the needs of our customers, our reputation could be adversely affected, our market share could decline and we could be subject to liability claims.

Our services are inherently complex and may contain material defects or errors. Any defects either in functionality or that cause interruptions in the availability of our services, as well as user error, could result in:

The costs incurred in correcting any material defects or errors might be substantial and could adversely affect our operating results.

Because of the large amount of data that we collect and manage, it is possible that hardware failures, errors in our systems or user errors could result in data loss or corruption that our customers regard as significant. Furthermore, the availability or performance of our services could be adversely affected by a number of factors, including customers’ inability to access the internet, the failure of our network or software systems, security breaches or variability in customer traffic for our services. We may be required to issue credits or refunds for prepaid amounts related to unused services or otherwise be liable to our customers for damages they may incur resulting from some of these events. In addition to potential liability, if we experience interruptions in the availability of our services, our reputation could be adversely affected, which could result in the loss of customers. For example, our customers access our services through their internet service providers. If a service provider fails to provide sufficient capacity to support our services or otherwise experiences service outages, such failure could interrupt our customers’ access to our services, adversely affect their perception of our services’ reliability and consequently reduce our revenue.

Our errors and omissions insurance may be inadequate or may not be available in the future on acceptable terms, or at all. In addition, our policy may not cover all claims made against us, and defending a lawsuit, regardless of its merit, could be costly and divert management’s attention.

Furthermore, we will need to ensure that our services can scale to meet the needs of our customers, particularly as we continue to focus on larger enterprise customers. If we are not able to provide our services at the scale required by our customers, potential customers may not adopt our solution and existing customers may not renew their agreements with us.

If the prices we charge for our services are unacceptable to our customers, our operating results will be harmed.

As the market for our services matures, or as new or existing competitors introduce new products or services that compete with ours, we may experience pricing pressure and be unable to renew our agreements with existing customers or attract new customers at prices that are consistent with our pricing model and operating budget. If this were to occur, it is possible that we would have to change our pricing model or reduce our prices, which could harm our revenue, gross margin and operating results.

Sales to customers outside the United States or with international operations expose us to risks inherent in international sales.

A key element of our growth strategy is to expand our international operations and develop a worldwide customer base. To date, we have not realized a substantial portion of our revenue from customers outside the

21

Table of Contents

United States. Operating in international markets requires significant resources and management attention and will subject us to regulatory, economic, geographic and political risks that are different from those in the United States. Because of our limited experience with international operations and significant differences between international and U.S. markets, our international expansion efforts may not be successful in creating demand for our services outside of the United States or in effectively selling subscriptions to our services in all of the international markets we enter. In addition, we will face specific risks in doing business internationally that could adversely affect our business, including:

We both sell our services and incur operating expenses in various currencies. Therefore, fluctuations in the value of the U.S. dollar and foreign currencies may impact our operating results when translated into U.S. dollars. We currently manage our exchange rate risk by matching foreign currency cash balances with payables and by maintaining minimal non-USD cash reserves, but do not have any other hedging programs in place to limit the risk of exchange rate fluctuation. In the future, however, to the extent our foreign currency exposures become more material, we may elect to deploy normal and customary hedging practices designed to more proactively mitigate such exposure. We cannot be certain such practice will ultimately be available and/or effective at mitigating all foreign currency risk to which we are exposed. If we are unsuccessful in detecting material exposures in a timely manner, our deployed hedging strategies are not effective, or there are no hedging strategies available for certain exposures which are prudent given the risks associated and the potential mitigation of the underlying exposure achieved, our operating results or financial position could be adversely affected in the future.

Failure to adequately expand our direct sales force and successfully maintain our online sales experience will impede our growth.

We will need to continue to expand and optimize our sales infrastructure in order to grow our customer base and our business. We plan to continue to expand our direct sales force, both domestically and internationally. Identifying and recruiting qualified personnel and training them requires significant time, expense and attention. Our business may be adversely affected if our efforts to expand and train our direct sales force do not generate a corresponding increase in revenue. If we are unable to hire, develop and retain talented sales personnel or if new

22

Table of Contents

direct sales personnel are unable to achieve desired productivity levels in a reasonable period of time, we may not be able to realize the intended benefits of this investment or increase our revenue.

We maintain our Box website to efficiently service our high volume, low dollar customer transactions and certain customer inquiries. Our goal is to continue to evolve this online experience so it effectively serves the increasing and changing needs of our growing customer base. If we are unable to maintain the effectiveness of our online solution to meet the future needs of our online customers, we could see reduced online sales volumes as well as a decrease in our sales efficiency which could adversely affect our results of operations.

If we are unable to maintain and promote our brand, our business and operating results may be harmed.

We believe that maintaining and promoting our brand is critical to expanding our customer base. Maintaining and promoting our brand will depend largely on our ability to continue to provide useful, reliable and innovative services, which we may not do successfully. We may introduce new features, products, services or terms of service that our customers do not like, which may negatively affect our brand and reputation. Additionally, the actions of third parties may affect our brand and reputation if customers do not have a positive experience using third-party apps or other services that are integrated with Box. Maintaining and enhancing our brand may require us to make substantial investments, and these investments may not achieve the desired goals. If we fail to successfully promote and maintain our brand or if we incur excessive expenses in this effort, our business and operating results could be adversely affected.

Our growth depends in part on the success of our strategic relationships with third parties.

In order to grow our business, we anticipate that we will continue to depend on our relationships with third parties, such as alliance partners, distributors, system integrators and developers. For example, we have entered into agreements with partners to market, resell, integrate with or endorse our services. We also partner with channel partners and resellers to sell our services. Identifying partners and resellers, and negotiating and documenting relationships with them, requires significant time and resources. Also, we depend on our ecosystem of system integrators and developers to create applications that will integrate with our platform. Our competitors may be effective in providing incentives to third parties to favor their products or services, or to prevent or reduce subscriptions to our services. In addition, acquisitions of our partners by our competitors could result in a decrease in the number of current and potential customers, as our partners may no longer facilitate the adoption of our services by potential customers.

If we are unsuccessful in establishing or maintaining our relationships with third parties, our ability to compete in the marketplace or to grow our revenue could be impaired and our operating results may suffer. Even if we are successful, we cannot assure you that these relationships will result in increased customer usage of our services or increased revenue.

Furthermore, if our partners and resellers fail to perform as expected, our reputation may be harmed and our business and operating results could be adversely affected.

We depend on our ecosystem of system integrators and developers to create applications that will integrate with our platform.

We depend on our partner ecosystem of system integrators and developers to create applications that will integrate with our platform. This presents certain risks to our business, including:

23

Many of these risks are not within our control to prevent, and our brand may be damaged if these applications do not perform to our users’ satisfaction and that dissatisfaction is attributed to us.

Our corporate culture has contributed to our success, and if we cannot maintain this culture as we grow, we could lose the innovation, creativity and teamwork fostered by our culture, and our business may be harmed.

We believe that our culture has been and will continue to be a key contributor to our success. From January 31, 2014 to January 31, 2015, we increased the size of our workforce by 186 employees, and we expect to continue to hire aggressively as we expand. If we do not continue to develop our corporate culture or maintain our core values as we grow and evolve both in the United States and internationally, we may be unable to foster the innovation, creativity and teamwork we believe we need to support our growth. Moreover, liquidity available to our employee security holders because of our initial public offering could lead to disparities of wealth among our employees, which could adversely impact relations among employees and our culture in general. Our transition from a private company to a public company may result in a change to our corporate culture, which could harm our business.

Our services contain open source software, and we license some of our software through open source projects, which may pose particular risks to our proprietary software, products, and services in a manner that could have a negative impact on our business.

We use open source software in our services and will use open source software in the future. In addition, we regularly contribute software source code to open source projects under open source licenses or release internal software projects under open source licenses, and anticipate doing so in the future. The terms of many open source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and there is a risk that open source software licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to provide or distribute our services. Additionally, we may from time to time face claims from third parties claiming ownership of, or demanding release of, the open source software or derivative works that we developed using such software, which could include our proprietary source code, or otherwise seeking to enforce the terms of the applicable open source license. These claims could result in litigation and could require us to make our software source code freely available, purchase a costly license or cease offering the implicated services unless and until we can re-engineer them to avoid infringement. This re-engineering process could require significant additional research and development resources, and we may not be able to complete it successfully. In addition to risks related to license requirements, use of certain open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or controls on the origin of software. Additionally, because any software source code we contribute to open source projects is publicly available, our ability to protect our intellectual property rights with respect to such software source code may be limited or lost entirely, and we are unable to prevent our competitors or others from using such contributed software source code. Any of these risks could be difficult to eliminate or manage, and, if not addressed, could have a negative effect on our business, financial condition and operating results.

Future acquisitions and investments could disrupt our business and harm our financial condition and operating results.

Our success will depend, in part, on our ability to expand our services and grow our business in response to changing technologies, customer demands, and competitive pressures. In some circumstances, we may choose to do so through the acquisition of complementary businesses and technologies rather than through internal

development, including, for example, our recent acquisitions of Crocodoc, Inc., a company with advanced HTML5 based document rendering technology, Streem, a company with technology that allows users to mount a cloud drive onto their computer and MedXT, a company with technology that allows us to display medical images (DICOM) files in an online and mobile viewer. The identification of suitable acquisition candidates can be difficult, time-consuming and costly, and we may not be able to successfully complete identified acquisitions. The risks we face in connection with acquisitions include:

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to incur unanticipated liabilities, and harm our business generally. Future acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses, incremental operating expenses or the write-off of goodwill, any of which could harm our financial condition or operating results.

We may require additional capital to support our operations or the growth of our business, and we cannot be certain that this capital will be available on reasonable terms when required, or at all.

On occasion, we may need additional financing to operate or grow our business. Our ability to obtain additional financing, if and when required, will depend on investor and lender demand, our operating performance, the condition of the capital markets and other factors. We cannot guarantee 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, 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 existing stockholders may experience dilution. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support the operation or growth of our business could be significantly impaired and our operating results may be harmed.

Financing agreements we are party to or may become party to may contain operating and financial covenants that restrict our business and financing activities.

Our existing credit agreement with certain lenders contains certain operating and financial restrictions and covenants, including the prohibition of the incurrence of certain indebtedness and liens, the prohibition of certain investments, restrictions against certain merger and consolidation transactions, certain restrictions against the

25

Table of Contents

disposition of assets and the requirement to maintain a minimum level of liquidity. These restrictions and covenants, as well as those contained in any future financing agreements that we may enter into, may restrict our ability to finance our operations, engage in, expand or otherwise pursue our business activities and strategies. Our ability to comply with these covenants may be affected by events beyond our control, and breaches of these covenants could result in a default under the credit agreement and any future financial agreements that we may enter into. If not waived, defaults could cause our outstanding indebtedness under our credit agreement and any future financing agreements that we may enter into to become immediately due and payable.

Adverse economic conditions may negatively impact our business.

Our business depends on the overall demand for Enterprise Content Collaboration and on the economic health of our current and prospective customers. The financial recession resulted in a significant weakening of the economy in the United States, Europe and worldwide, more limited availability of credit, a reduction in business confidence and activity, and other difficulties that may affect one or more of the industries to which we sell our services. In addition, there has been pressure to reduce government spending in the United States, and tax increases and spending cuts at the Federal level (the sequester) have gone into effect. In the event lawmakers cannot agree on matters such as the national debt ceiling or future budgets, the United States could default on its obligations. This may reduce demand for our services from organizations that receive funding from the U.S. government and this could negatively affect the U.S. economy, which could further reduce demand for our services. Furthermore, the economies of certain European countries have been experiencing difficulties associated with high sovereign debt levels, weakness in the banking sector and uncertainty over the future of the eurozone. We have operations in the United Kingdom, Germany and France, and likely will expand these to other Eurozone countries in future years, and current and potential customers in Europe. If economic conditions in Europe and other key markets for our services continue to remain uncertain or deteriorate further, many customers may delay or reduce their information technology spending. This could result in reductions in sales of our services, longer sales cycles, reductions in subscription duration and value, slower adoption of new technologies and increased price competition. Any of these events would likely have an adverse effect on our business, operating results and financial position. In addition, there can be no assurance that Enterprise Content Collaboration spending levels will increase following any recovery.

Changes in laws and regulations related to the internet or changes in the internet infrastructure itself may diminish the demand for our services, and could have a negative impact on our business.

The future success of our business depends upon the continued use of the internet as a primary medium for commerce, communication and business services. Federal, state or foreign government bodies or agencies have in the past adopted, and may in the future adopt, laws or regulations affecting the use of the internet as a commercial medium. Changes in these laws or regulations could require us to modify our services in order to comply with these changes. In addition, government agencies or private organizations may begin to impose taxes, fees or other charges for accessing the internet or commerce conducted via the internet. These laws or charges could limit the growth of internet-related commerce or communications generally, or result in reductions in the demand for internet-based services such as ours.

In addition, the use of the internet and, in particular, the cloud as a business tool could be adversely affected due to delays in the development or adoption of new standards and protocols to handle increased demands of internet activity, security, reliability, cost, ease of use, accessibility, and quality of service. The performance of the internet and its acceptance as a business tool have been adversely affected by “viruses,” “worms” and similar malicious programs, and the internet has experienced a variety of outages and other delays as a result of damage to portions of its infrastructure. If the use of the internet is adversely affected by these issues, demand for our services could suffer.

We employ third-party licensed software for use in or with our services, and the inability to maintain these licenses or errors in the software we license could result in increased costs, or reduced service levels, which would adversely affect our business.

Our services incorporate certain third-party software obtained under licenses from other companies. We anticipate that we will continue to rely on such third-party software and development tools in the future. Although we believe that there are commercially reasonable alternatives to the third-party software we currently license, this may not always be the case, or it may be difficult or costly to replace. In addition, integration of the software used in our services with new third-party software may require significant work and require substantial investment of our time and resources. Also, to the extent that our services depend upon the successful operation of third-party software in conjunction with our software, any undetected errors or defects in this third-party software could prevent the deployment or impair the functionality of our services, delay new services introductions, result in a failure of our services, and injure our reputation. Our use of additional or alternative third-party software would require us to enter into additional license agreements with third parties.

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 are subject to the reporting requirements of the Securities Exchange, the Sarbanes-Oxley Act and the listing standards of the New York Stock Exchange (the NYSE). 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 properly recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. We are also continuing to improve our internal control over financial reporting. We have expended, and anticipate that we will continue to expend, significant resources in order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting.

Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business, including increased complexity resulting from our international expansion. Further, weaknesses in our disclosure controls or our 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 operating results 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 could also adversely affect the results of management reports and independent registered public accounting firm audits of our internal control over financial reporting that we will 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 market 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 NYSE.

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 are 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 audit the effectiveness

27

Table of Contents

of our internal control over financial reporting until after we are no longer an “emerging growth company,” as defined in the JOBS Act. At such time, our independent registered public accounting firm may 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 have a material and adverse effect on our business and operating results, and cause a decline in the market price of our Class A common stock.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our Class A common stock less attractive to investors.

We are an emerging growth company, 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 have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, 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 stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company for up to five years following the completion of our initial public offering. We will remain an emerging growth company until the earliest to occur of (i) the last day of the fiscal year in which we have more than $1.0 billion in annual revenue; (ii) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (iii) the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities; and (iv) the last day of the fiscal year ending after the fifth anniversary of the completion of our initial public offering. 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 we make to avail ourselves of these exemptions, there may be a less active trading market for our Class A common stock and the market price of our Class A common stock may be more volatile.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this accommodation allowing for delayed adoption of new or revised accounting standards, and, therefore, we are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

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

As of January 31, 2015, we had U.S. federal net operating loss carryforwards of approximately $342.0 million, state net operating loss carryforwards of approximately $332.3 million, and foreign net operating loss carryforwards of approximately $65.9 million. Under Sections 382 and 383 of Internal Revenue Code of 1986, as amended (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 tax attributes, such as research tax credits, to offset its post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We have in the past experienced an ownership change which has impacted our ability to fully realize the benefit of these net operating loss carryforwards. If we experience additional ownership changes as a result of our initial public offering or future transactions in our stock, then we may be further limited in our ability to use our net operating loss carryforwards and other tax assets to reduce taxes owed on the net taxable income that we earn. Any such limitations on the ability to use our net operating loss carryforwards and other tax assets could adversely impact our business, financial condition and operating results.

Tax laws or regulations could be enacted or changed and existing tax laws or regulations could be applied to us or to our customers in a manner that could increase the costs of our services and adversely impact our business.

The application of federal, state, local and international tax laws to services provided electronically is unclear and continuously evolving. Income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted or amended at any time, possibly with retroactive effect, and could be applied solely or disproportionately to services provided over the internet. These enactments or amendments could adversely affect our sales activity due to the inherent cost increase the taxes would represent and ultimately result in a negative impact on our operating results and cash flows.

In addition, existing tax laws, statutes, rules, regulations or ordinances could be interpreted or applied adversely to us, possibly with retroactive effect, which could require us or our customers to pay additional tax amounts, as well as require us or our customers to pay fines or penalties, as well as interest for past amounts. If we are unsuccessful in collecting such taxes due from our customers, we could be held liable for such costs, thereby adversely impacting our operating results and cash flows.

We may be subject to additional tax liabilities.

We are subject to income, sales, use, value added and other taxes in the United States and other countries in which we conduct business, and such laws and rates vary by jurisdiction. Certain jurisdictions in which we do not collect sales, use, value added or other taxes on our sales may assert that such taxes are applicable, which could result in tax assessments, penalties and interest, and we may be required to collect such taxes in the future. Significant judgment is required in determining our worldwide provision for income taxes. These determinations are highly complex and require detailed analysis of the available information and applicable statutes and regulatory materials. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical tax practices, provisions and accruals. If we receive an adverse ruling as a result of an audit, or we unilaterally determine that we have misinterpreted provisions of the tax regulations to which we are subject, there could be a material effect on our tax provision, net income or cash flows in the period or periods for which that determination is made. In addition, liabilities associated with taxes are often subject to an extended or indefinite statute of limitations period. Therefore, we may be subject to additional tax liability (including penalties and interest) for a particular year for extended periods of time.

Our reported financial results 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, the 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 financial results, and could affect the reporting of transactions completed before the announcement of a change.

Risks Related to Ownership of Our Class A Common Stock

The dual class structure of our common stock has the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of our initial public offering, including our executive officers, employees and directors and their affiliates, which limits your ability to influence the outcome of important transactions, including a change in control.

Our Class B common stock has 10 votes per share, and our Class A common stock has one vote per share. Stockholders who hold shares of our Class B common stock, including our executive officers, employees and directors and their affiliates, collectively hold approximately 98.6% of the voting power of our outstanding

29

Table of Contents

capital stock. Because of the ten-to-one voting ratio between our Class B common stock and Class A common stock the holders of our Class B common stock collectively continue to control a majority of the combined voting power of our capital stock and therefore are able to control all matters submitted to our stockholders for approval so long as the shares of our Class B common stock represent at least 9.1% of all outstanding shares of our Class A common stock and Class B common stock. These holders of our Class B common stock may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentrated control may have the effect of delaying, preventing or deterring a change in control of our company, could deprive our stockholders of an opportunity to receive a premium for their capital stock as part of a sale of our company and might ultimately affect the market price of our Class A common stock.

Future transfers by holders of our Class B common stock will generally result in those shares converting into shares of our Class A common stock, subject to limited exceptions, such as certain transfers effected for estate planning or charitable purposes. The conversion of shares of our Class B common stock into shares of our Class A common stock 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, Messrs. Levie, Levin and Smith retain a significant portion of their holdings of our Class B common stock for an extended period of time, they could control a significant portion of the voting power of our capital stock for the foreseeable future. As board members, Messrs. Levie, Levin and Smith each owe a fiduciary duty to our stockholders and must act in good faith and in a manner they reasonably believe to be in the best interests of our stockholders. As stockholders, Messrs. Levie, Levin and Smith are entitled to vote their shares in their own interests, which may not always be in the interests of our stockholders generally.

Anti-takeover provisions contained in our amended and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions which could have the effect of rendering more difficult, delaying or preventing an acquisition deemed undesirable by our board of directors. Among other things, our amended and restated certificate of incorporation and amended and restated bylaws include provisions:

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation Law, which prevents certain stockholders holding more than 15% of our outstanding capital stock from engaging in certain business combinations without approval of the holders of at least two-thirds of our outstanding common stock not held by such stockholder.

30

Table of Contents

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock, and could also affect the price that some investors are willing to pay for our Class A common stock.

The market price of our Class A common stock has been and will likely continue to be volatile, and you could lose all or part of your investment.

Prior to our initial public offering, there had been no public market for shares of our Class A common stock. The market price of our Class A common stock since our initial public offering has been and may continue to be subject to wide fluctuations in response to various factors, some of which are beyond our control and may not be related to our operating performance. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this Annual Report on Form 10-K, factors that could cause fluctuations in the market price of our Class A common stock include the following:

In addition, in the past, following periods of volatility in the overall market and 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.

A total of 105,232,718, or 87.8%, of the shares of our capital stock outstanding as of February 28, 2015 are restricted from immediate resale but may be sold in the near future. The large number of shares of our capital stock eligible for public sale or subject to rights requiring us to register them for public sale could depress the market price of our Class A common stock.

The market price of our Class A common stock could decline as a result of sales of a large number of shares of our Class A common stock in the market, and the perception that these sales could occur may also depress the market price of our Class A common stock. As of January 31, 2015, there were 119,655,030 shares of our capital stock outstanding. Our executive officers, directors and the holders of substantially all of our capital stock and securities convertible into or exchangeable for our capital stock have entered into market standoff agreements with us and/or lock-up agreements with the underwriters of our initial public offering under which they have agreed, subject to specific exceptions, not to sell any shares of our capital stock prior to July 23, 2015. As a result of these agreements and the provisions of our investors’ rights agreement, all shares of our capital stock will be available for sale in the public market beginning on July 23, 2015, subject in some cases to the volume and other restrictions of Rule 144 and Rule 701 under the Securities Act of 1933, as amended, as well as our insider trading policy.

Following the expiration of the lock-up agreements referred to above, stockholders owning an aggregate of up to 92,886,469 shares of our capital stock can require us to register shares of our capital stock owned by them for public sale in the United States. In addition, we filed a registration statement to register 59,837,528 shares of our capital stock reserved for future issuance under our equity compensation plans. As a result, subject to the satisfaction of applicable exercise periods and expiration of the market standoff agreements and lock-up agreements referred to above, the shares of our capital stock issued upon exercise of outstanding options to purchase shares of our Class B common stock and upon the vesting of outstanding RSUs will be available for immediate resale in the United States in the open market.

Sales of our Class A common stock as restrictions end or pursuant to registration rights may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause the market price of our Class A common stock to fall and make it more difficult for you to sell shares of our Class A common stock.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business, our market or our competitors, or if they adversely change their recommendations regarding our Class A common stock, the market price of our Class A common stock and trading volume could decline.

The trading market for our Class A common stock is influenced, to some extent, by the research and reports that securities or industry analysts publish about us, our business, our market or our competitors. If any of the analysts who cover us adversely change their recommendations regarding our Class A common stock or provide more favorable recommendations about our competitors, the market price of our Class A common stock would likely decline. If any of the analysts who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price of our Class A common stock or trading volume to decline.

We do not expect to declare any dividends in the foreseeable future.

We do not anticipate declaring any cash dividends to holders of our Class A common stock in the foreseeable future. Consequently, investors may need to rely on sales of our Class A common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase shares of our Class A common stock.

Item 1B. UNRESOLVED STAFF COMMENTS

Not applicable.

Item 2. PROPERTIES

Our corporate headquarters, which includes research and development, sales, marketing, business operations and executive offices, is located in Los Altos, California. It consists of approximately 97,000 square feet of space under a lease that expires in fiscal 2016. In September 2014, we entered into a lease for approximately 340,000 square feet in Redwood City, California, which expires in fiscal 2029. We plan to use this space as our new corporate headquarters and to sublease a portion of this space.

We also lease offices in San Francisco, California; Austin, Texas; New York, New York; London, England, Paris, France, and Tokyo, Japan. We intend to procure additional space as we add employees in current locations and expand geographically. We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate expansion of our operations.

Item 3. LEGAL PROCEEDINGS

On June 5, 2013, Open Text S.A. (Open Text) filed a lawsuit against us in U.S. District Court, Eastern District of Virginia, alleging that our core cloud software and Box Edit application directly and indirectly infringe 12 patents in three patent families that Open Text acquired through its acquisition of various companies: U.S. Patent No. 7,062,515, titled “System and Method for the Synchronization of a File in a Cache,” U.S. Patent No. 7,590,665, titled “System and Method for the Synchronization of a File in a Cache,” and U.S. Patent No. 8,117,152, titled “System and Method for the Synchronization of a File in a Cache,” (collectively, the File Synchronization Patents), U.S. Patent No. 6,223,177, titled “Network Based Groupware System,” U.S. Patent No. 6,917,962, titled “Web-Based Groupware System,” U.S. Patent No. 7,287,055, titled “Web-Based Groupware System,” U.S. Patent No. 7,299,258, titled “Web-Based Groupware System,” U.S. Patent No. 7,320,018, titled “Web-Based Groupware System,” U.S. Patent No. 7,734,694, titled “Web-Based Groupware System,” and U.S. Patent No. 8,176,122, titled “Web-Based Groupware System,” (collectively, the “Groupware Patents”), and U.S. Patent No. 7,647,372, titled “Method and System for Facilitating Marketing Dialogues,” and U.S. Patent No. 7,975,007, titled “Method and System for Facilitating Marketing Dialogues,” (collectively, the “Dialog Patents”). On October 18, 2013, the Virginia court granted our motion to transfer and the case was transferred to the U.S. District Court for the Northern District of California. Open Text sought preliminary and permanent injunctions against infringement, treble damages, and attorneys’ fees.

On September 13, 2013, Open Text filed a motion for preliminary injunction seeking to enjoin us from providing our Box Edit feature to companies with more than 100 users. On April 9, 2014, the California court denied Open Text’s motion for preliminary injunction, finding that (1) Open Text failed to meet its burden to show irreparable harm, (2) Open Text failed to show a reasonable likelihood of success on the merits of its case, and (3) we have raised a substantial question as to the validity of the patents asserted during the preliminary injunction proceedings.

On September 19, 2014, in a related action, Open Text S.A. v. Alfresco Software Ltd., et al., Case No. 13-cv-04843-JD, the Court granted the Alfresco Defendants’ motion to dismiss with prejudice the asserted claims of the Dialog Patents, finding the asserted claims of the Dialog Patents patent ineligible under 35 U.S.C. § 101. On January 20, 2015, the Court entered an Order granting our motion for judgment on the pleadings as to the asserted patent claims of the Groupware Patents. The Court found that the asserted patent claims of the Groupware Patents are invalid because they claim non-patentable subject matter. As a result of the Court’s January 20, 2015 order and other pretrial orders, the lawsuit was narrowed to four total claims across the three remaining File Synchronization Patents accusing the Company’s Box Edit feature and Box Android application.

Table of Contents

Trial commenced on February 2, 2015. On February 13, 2015, the jury returned a verdict, finding the asserted claims of the File Synchronization patents infringed and were not invalid. The jury awarded damages in favor of Open Text in a lump sum and fully paid-up royalty in the amount of $4.9 million. The Court found no willful infringement of the asserted claims and foreclosed Open Text’s request for a permanent injunction since the jury returned a lump-sum award. On February 19, 2015, Open Text filed a notice of appeal to the United States Court of Appeals for the Federal Circuit from the Court’s Order granting our motion for judgment of invalidity of the Groupware Patents. On March 9, 2015, Open Text filed a first amended notice of appeal from additional orders by the Court. We intend to continue to defend the lawsuit vigorously which may include filing post-trial challenges to the verdict and filing appeals in connection with the case. While we continue to believe we have valid defenses to Open Text’s claims, an adverse outcome to the litigation could result in a material adverse effect on our business.

In addition, from time to time, we are a party to litigation and subject to claims that arise in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

PART II

Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information for Common Stock

Our Class A common stock began trading on the New York Stock Exchange under the symbol “BOX” on January 23, 2015. Prior to that date, there was no public trading market for any of our common stock. The following table sets forth the high and low sales price per share of our Class A common stock as reported on the New York Stock Exchange for the period indicated:

Holders of Record

As of February 28, 2015, there were 2 holders of record of our Class A common stock and 985 holders of record of our Class B common stock. Because many of our shares of Class A common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

Dividend Policy

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings for use in the operation of our business and do not anticipate paying any dividends on our capital stock in the foreseeable future. Any future determination to declare dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our board of directors may deem relevant.

Common Stock Issuances in Connection with Acquisitions

From February 1, 2014 through January 31, 2015, we issued an aggregate of 344,667 shares of our Class B common stock in connection with our acquisitions of certain companies as consideration to individuals and entities who were former service providers and/or stockholders of such companies.

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering. Unless otherwise specified above, the Registrant believes these transactions were exempt from registration under the Securities Act in reliance upon Section 4(2) of the Securities Act (or Regulation S or Regulation D promulgated thereunder), or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by an issuer not involving any public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates issued in these transactions. All recipients had adequate access, through their relationships with the Registrant, to information about the Registrant. The sales of these securities were made without any general solicitation or advertising.

Use of Proceeds

The Registration Statement on Form S-1 (File No. 333-194767) (the Form S-1) for our initial public offering of our Class A common stock was declared effective by the SEC on January 22, 2015. The Registration Statement on Form S-1 registered an aggregate of 14,375,000 shares of our Class A common stock, including 1,875,000 shares registered to cover an over-allotment option. On January 28, 2015, we closed our initial public offering and sold 14,375,000 shares of our Class A common stock at a public offering price of $14.00 per share for an aggregate offering price of approximately $201.3 million. We received net proceeds of $187.2 million after deducting underwriting discounts and commissions of $14.1 million but before deducting offering costs of $5.7 million.

The underwriters of our initial public offering were Morgan Stanley & Co. LLC, Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, BMO Capital Markets Corp., Canaccord Genuity Inc., Pacific Crest Securities LLC, Raymond James & Associates, Inc. and Wells Fargo Securities, LLC. We paid to the underwriters of our initial public offering an underwriting discount totaling approximately $14.1 million. In addition, we incurred offering expenses of approximately $5.7 million, of which $2.9 million and $588,000, respectively, was paid in the years ended January 31, 2015 and 2014, and the remaining $2.2 million will be paid after January 31, 2015. Thus, the net offering proceeds, after deducting underwriting discounts and offering expenses, were approximately $181.5 million. No payments were made to our directors or officers or their associates, holders of 10% or more of any class of our equity securities or any affiliates.

There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the SEC on January 23, 2015 pursuant to Rule 424(b)(4).

Performance Graph

We have elected not to include a performance graph in this Annual Report on Form 10-K because the period between the date that our Class A common stock began trading on the NYSE and the end of our most recently completed fiscal year is 30 days or less.

Overview

Box provides a cloud-based, mobile-optimized Enterprise Content Collaboration platform that enables organizations of all sizes to easily and securely manage their content from anywhere. Our platform enables users to collaborate on content both internally and externally, build workflows to power mission-critical processes and deploy compliance and security features that are essential in certain industries. We have built our platform to work across multiple file formats, application environments, operating systems and devices. Our mission is to make organizations more productive, competitive and collaborative by connecting people and their most important information.

We were founded and publicly launched our platform in 2005 with a simple but powerful idea: to make it incredibly easy for people to securely manage, share and collaborate on their most important content online. In 2006, we introduced a free version of our product in order to rapidly grow our user base, surpassing one million registered users by July 2007. As users began to bring our solution into the workplace, we learned that businesses were eager for a solution to empower user-friendly content sharing and collaboration in a secure, manageable way. Starting in 2007, we began enhancing our platform to serve businesses and large enterprises, which meant expanding our business functionality with features such as our administrative console, identity integration, activity reporting and full-text search. To further satisfy the requirements of IT departments in large organizations, we began to invest heavily in enhancing the security of our platform. Also in 2007, we began to build an enterprise sales team. The continual evolution of our platform features allowed our sales team to sell into increasingly larger organizations. To empower users to work securely from anywhere, we built native applications for all major mobile platforms. The introduction of our iPad application in 2010 further accelerated enterprise adoption of our platform. In 2012, we introduced our Box OneCloud platform and our Box Embed framework to encourage developers and independent software vendors (ISVs) to build powerful applications that connect to Box, furthering the reach of the Box service. In recent years, we have expanded our global presence, opening our first international office in London in 2012, followed by Paris and Tokyo in 2013. In 2014, we continued to expand our international presence further. For the year ended January 31, 2015, revenue from non-U.S. customers represented 20% of our revenue. We expect our revenue from non-U.S. customers to increase at a higher rate than our revenue from U.S. customers over time.

We offer our solution to our customers as a subscription-based service, with subscription fees based on the requirements of our customers, including the number of users and functionality deployed. The majority of our customers subscribe to our service through one-year contracts, although we also offer our services for terms ranging between one month to three years or more. We typically invoice our customers at the beginning of the term, in multiyear, annual, quarterly or monthly installments. We recognize revenue ratably over the term of the subscription period.

Our objective is to build an enduring business that creates sustainable revenue and earnings growth over the long term. To best achieve this objective, we focus on growing the number of Box users and paying organizations through direct field sales, direct inside sales, indirect channel sales and through word-of-mouth by individual users, some of whom use our services at no cost. Individual users and organizations can also simply

39

Table of Contents

sign up to use our solution on our website. We believe this approach not only helps us build a critical mass of users but also has a viral effect within organizations as more of their employees use our service and encourage their IT professionals to deploy our services to a broader user base.

We have achieved significant growth in a short period of time. Our user base includes over 34 million registered users across more than 280,000 organizations. We define a registered user as a Box account that has been provisioned to a unique user ID. As of January 31, 2015, approximately 90% of our registered users are non-paying users who have independently registered for accounts and approximately 10% of our registered users are paying users who register as part of a larger enterprise or business account or by using a personal account. We currently have over 45,000 paying organizations, and our solution is offered in 22 languages. We define paying organizations as separate and distinct buying entities, such as a company, an educational or government institution, or a distinct business unit of a large corporation, that have entered into a subscription agreement with us to utilize our services.

Organizations typically purchase our solution in the following ways: (i) employees in one or more small groups within the organization may individually purchase our service; (ii) organizations may purchase IT-sponsored, enterprise-level agreements with deployments for specific, targeted use cases ranging from tens to thousands of user seats; or (iii) organizations may purchase IT- sponsored, enterprise-level agreements where the number of user seats sold is intended to accommodate and enable nearly all information workers within the organization in whatever use cases they desire to adopt over the term of the subscription.

For the 12 months ended January 31, 2015, 59% of our orders for subscription services were from new enterprise customers and expansion within existing enterprise customers. We consider enterprise customers to be organizations with at least 1,000 employees, as such organizations are the focus of our Enterprise Accounts sales team.

We intend to continue scaling our organization to meet the increasingly complex needs of our customers. Our sales and customer success teams are organized to efficiently serve organizations ranging from small businesses to the world’s largest global organizations. We have invested and expect to continue to invest heavily in our sales and marketing teams to sell our services around the world, as well as in our development efforts to deliver additional features and capabilities of our cloud services to address customers’ evolving needs. We also expect to continue to make significant investments in both our datacenter infrastructure to meet the needs of our growing user base and our professional services organization to address the strategic needs of our customers in more complex deployments and to drive broader adoption across a wide array of use cases. As a result of our continuing investments to scale our business in each of these areas, we do not expect to be profitable for the foreseeable future.

For the years ended January 31, 2015, 2014 and 2013, our revenue was $216.4 million, $124.2 million and $58.8 million, respectively, representing year-over-year growth of 74% and 111%, and our net losses were $168.2 million, $168.6 million and $112.6 million, respectively. Box is headquartered in Los Altos, California and operates offices in California, New York, Texas, London, Paris and Tokyo.

Fiscal Year End

We changed our fiscal year end from December 31 to January 31, effective for our fiscal year ended January 31, 2013.

Our Business Model

Our business model focuses on maximizing the lifetime value of a customer relationship. We make significant investments in acquiring new customers and believe that we will be able to achieve a positive return on these investments by retaining customers and expanding the size of our deployments within our customer base

40

Table of Contents

over time. In connection with the acquisition of new customers, we incur and recognize significant upfront costs. These costs include sales and marketing costs associated with acquiring new customers, such as sales commission expenses, a significant portion of which is expensed upfront and the remaining portion of which is expensed over the length of the non-cancellable subscription term, and marketing costs, which are expensed as incurred. Due to our subscription model, we recognize revenue ratably over the term of the subscription period, which commences when all of the revenue recognition criteria have been met. Although our objective is for each customer to be profitable for us over the duration of our relationship, the costs we incur with respect to any customer relationship, whether a new customer or an expansion within an existing customer, may exceed revenue in earlier periods because we recognize those costs faster than we recognize the associated revenue.

Because of these dynamics, we experience a range of profitability with our customers depending in large part upon what stage of the customer phase they are in. We generally incur higher sales and marketing expenses for new customers and existing customers who are still in an expanding stage. For new customers, our associated sales and marketing expenses typically exceed the first year revenue we recognize from those customers. For customers who are expanding their use of Box, we incur various associated marketing expenses as well as sales commission expenses, though we typically recognize higher revenue than sales and marketing expenses. For typical customers who are renewing their Box subscriptions, our associated sales and marketing expenses are significantly less than the revenue we recognize from those customers. These differences are primarily driven by the higher compensation we provide to our sales force for new customers and customer subscription expansions compared to the compensation we provide to our sales force for routine subscription renewals by customers. In addition, our sales and marketing expenses, other than the compensation we provide to our sales force, are generally higher for acquiring new customers versus expansions or renewals of existing customer subscriptions. We believe that, over time, as our existing customer base grows and a relatively higher percentage of our revenue is attributable to renewals versus new or expanding Box deployments, we will experience lower associated sales and marketing expenses as a percentage of revenue.

Key Business Metrics

We monitor the following key metrics to help us measure our performance, identify trends affecting our business, formulate financial projections, assess operational efficiencies and make strategic decisions. In addition to our results determined in accordance with GAAP, we believe the following non-GAAP financial and operational measures are useful in evaluating our operating performance.

Billings represent our revenue plus the change in deferred revenue in the period. Billings we record in any particular period reflect sales to new customers plus subscription renewals and expansion within existing customers, and represent amounts invoiced for subscription, premier support and professional services. We typically invoice our customers at the beginning of the term, in multiyear, annual, quarterly or monthly installments. If the customer elects to pay the full subscription amount at the beginning of the period, the total subscription amount for the entire term will be reflected in billings. If the customer elects to be invoiced annually or more frequently, only the amount billed for such period will be included in billings.

We consider billings a significant performance measure and a leading indicator of future revenue. Billings also help investors better understand our sales activity for a particular period, which is not necessarily reflected in our revenue as a result of the fact that we recognize subscription revenue ratably over the subscription term. We monitor billings to manage our business, make planning decisions, evaluate our performance and allocate resources. We believe that billings offers valuable supplemental information regarding the performance of our business and will help investors better understand the sales volumes and performance of our business.

Billings increased 41% in the year ended January 31, 2015 over the year ended January 31, 2014, and 103% in the year ended January 31, 2014 over the year ended January 31, 2013. The growth rate for our billings declined for the year ended January 31, 2015 compared to the year ended January 31, 2014, primarily due to a larger billings base in the year ended January 31, 2014 as our billings continued to increase over time, a higher percentage of invoices with quarterly and monthly installments, as well as fewer prepaid contracts with a service term of more than one year. The increase in billings was primarily driven by the addition of new customers with larger initial deployments and expansion with respect to the number of users within existing customers.

Retention Rate

We calculate our retention rate as of a period end by starting with the annual contract value (ACV) from customers with contract value of $5,000 or more as of 12 months prior to such period end (Prior Period ACV) and a subscription term of at least 12 months. We then calculate ACV from these same customers as of the current period end (Current Period ACV). Finally, we divide the aggregate Current Period ACV for the trailing 12 month period by the aggregate Prior Period ACV for the trailing 12 month period to arrive at our retention rate. We believe our retention rate is an important metric that provides insight into the long-term value of our subscription agreements and our ability to retain and grow revenue from our customer base. We focus on contracts that have a value of $5,000 or more because, over time, these customers give us the best indicator for the growth of our business and the potential for incremental business as they renew and expand their deployments, and contracts with these customers represented a substantial majority of our revenue for the year ended January 31, 2015. Retention rate is an operational metric and there is no comparable GAAP financial measure to which we can reconcile this particular key metric.

Our retention rate was approximately 126%, 136% and 144% as of January 31, 2015, 2014 and 2013, respectively. The calculation of our retention rate reflects both net user expansion and the loss of customers who

42

Table of Contents

do not renew their subscriptions with us, which was below 5% for enterprise customers of the Prior Period ACV for the 12 months ended January 31, 2015, a decrease from the 12 months ended January 31, 2014. Our retention rates consistently exceeded 100% and were primarily attributable to an increase in user expansion, from both enterprise and small and medium business customers. We believe our investments in product, Customer Success, and Box Consulting are driving improvements in customer retention. As we penetrate customer accounts, we expect our rate of growth in expansion to trend down over time but our retention rate to remain above 100% for the foreseeable future.

To provide investors with additional information regarding our financial results, we have disclosed in the table above and within this report billings, a non-GAAP financial measure. We have provided a reconciliation below of billings to revenue, the most directly comparable GAAP financial measure. We consider billings a significant performance measure and a leading indicator of future revenue. Billings also help investors better understand our sales activity for a particular period, which is not necessarily reflected in our revenue as a result of the fact that we recognize subscription revenue ratably over the subscription term. We monitor billings to manage our business, make planning decisions, evaluate our performance and allocate resources.

Our use of billings, a non-GAAP financial measure, has the following limitations as an analytical tool and should not be considered in isolation or as a substitute for revenue or an analysis of our results as reported under GAAP. Billings are recognized when invoiced, while the related revenue is recognized ratably over the term of the subscription or premier support services. When we invoice customers more frequently than their subscription period, amounts not yet invoiced will not be reflected in deferred revenue or billings. Also, other companies, including companies in our industry, may not use billings, may calculate billings differently, may have different billing frequencies, or may use other financial measures to evaluate their performance, all of which could reduce the usefulness of billings as a comparative measure.

A reconciliation of billings to revenue, the most directly comparable GAAP financial measure, is presented below:

Components of Results of Operations

Revenue

We derive our revenue from three sources: (1) subscription revenue, which is comprised of subscription fees from customers utilizing our cloud-based Enterprise Content Collaboration services that include routine customer support; (2) revenue from customers purchasing our premier support package; and (3) revenue from professional services such as implementing best practice use cases, project management and other implementation services.

To date, practically all of our revenue has been derived from subscription and premier support services. Subscription and premier support revenue is driven primarily by the number of customers, the number of seats sold to each customer and the price of our services.

Subscription and premier support revenue is recognized ratably over the contract term beginning on the later of the date the service is provisioned to the customer and the date all other revenue recognition criteria have been

43

Table of Contents

met. Our subscription and support contracts are typically non-cancellable and do not contain refund-type provisions. The majority of our customers subscribe to our service through one-year contracts, although we also offer our services for terms ranging between one month to three years or more. We typically invoice our customers at the beginning of the term, in multiyear, annual, quarterly or monthly installments. Amounts that have been invoiced are initially recorded as deferred revenue and are recognized ratably over the invoice period. Amounts that have not been invoiced are not reflected in deferred revenue. Revenue is recognized ratably over the subscription term.

Professional services revenue is recognized as the services are rendered for time and material contracts, and using the proportional performance method over the period the services are performed for fixed price contracts. Professional services revenue was not material for all periods presented.

Cost of Revenue

Our cost of revenue consists primarily of costs related to providing our cloud-based services to our paying customers, including employee compensation and related expenses for datacenter operations, customer support and professional services personnel, payments to outside infrastructure service providers, depreciation of servers and equipment, security services and other tools, as well as amortization of acquired technology. We allocate overhead such as rent, information technology costs and employee benefit costs to all departments based on headcount. As such, general overhead expenses are reflected in cost of revenue and each of the operating expense categories set forth below. We expect our cost of revenue to increase in dollars and may increase as a percentage of revenue as we continue to invest in our datacenter operations and customer support to support the growth of our business, our customer base, as well as our international expansion.

Operating Expenses

Our operating expenses consist of research and development, sales and marketing, and general and administrative expenses. Personnel costs are the most significant component of each category of operating expenses. Operating expenses also include allocated overhead costs for facilities, information technology costs and employee benefit costs.

Research and Development. Research and development expense consists primarily of employee compensation and related expenses, as well as allocated overhead. Our research and development efforts are focused on scaling our platform, adding enterprise grade features, functionality and security, and enhancing the ease of use of our cloud-based services. We expect our research and development expense to increase in dollars but decrease as a percentage of revenue over time, as we continue to invest in our future products and services.

Sales and Marketing. Sales and marketing expense consists primarily of employee compensation and related expenses, sales commissions, marketing programs, travel -related expenses, as well as allocated overhead. Marketing programs include but are not limited to advertising, events, corporate communications, brand building, and product marketing. Sales and marketing expense also consists of datacenter and customer support costs related to providing our cloud-based services to our free users. We market and sell our cloud-based services worldwide through our direct sales organization and through indirect distribution channels such as strategic resellers. We expect our sales and marketing expense to continue to increase in dollars but decrease as a percentage of revenue over time as we increase the size of our sales and marketing organization and expand our international presence.

General and Administrative. General and administrative expense consists primarily of employee compensation and related expenses for administrative functions including finance, legal, human resources and recruiting, and fees for external professional services as well as allocated overhead. External professional services fees are primarily comprised of outside legal, litigation, accounting, temporary services, audit and outsourcing services. We expect our general and administrative expense to increase in dollars but decrease as a percentage of revenue over time as we incur additional costs related to operating as a publicly-traded company including increased headcount and audit, legal, regulatory and other related fees.

Remeasurement of Redeemable Convertible Preferred Stock Warrant Liability

The remeasurement of redeemable convertible preferred stock warrant liability includes charges from the change in fair value of our redeemable convertible preferred stock warrant liability as of each period end. These redeemable convertible preferred stock warrants remained outstanding until the exercise of the warrants or the completion of our initial public offering, at which time the warrant liability was remeasured to fair value and reclassified to additional paid-in capital. As of January 31, 2015, there were no longer any redeemable convertible preferred stock warrants outstanding.

Interest Income (Expense), Net

Interest income consists of interest earned on our cash and cash equivalents and marketable securities balances. We have historically invested our cash in overnight deposits and short-term, investment-grade corporate securities. Interest expense consists of interest charges, fees on letters of credit and the amortization of capitalized debt issuance costs associated with our outstanding borrowings.

Other Income (Expense), Net

Other income (expense), net consists primarily of gains and losses from foreign currency transactions and other income (expense).

Provision (Benefit) for Income Taxes

Provision (benefit) for income taxes consists primarily of state income taxes in the United States and income taxes in certain foreign jurisdictions in which we conduct business offset by the tax benefit recognized from the release of our valuation allowance in connection with acquisitions. At January 31, 2015, we had federal and state net operating loss carryforwards (NOLs) of $342.0 million and $332.3 million, which expire at various dates beginning in 2025 and 2016, respectively. We also had foreign net operating loss carryforwards of approximately $65.9 million, which do not expire. Federal and state tax laws impose limitations on the utilization of NOLs in the event of an “ownership change” for tax purposes, as defined in Section 382 of the Internal Revenue Code. In the past, we have experienced an ownership change which has impacted our ability to fully realize the benefit of these NOLs. If we experience additional ownership changes, our ability to utilize our NOLs may be further limited.

Results of Operations

The following tables set forth our results of operations for the periods presented in dollars and as a percentage of our revenue:

46

Table of Contents

Comparison of the Years Ended January 31, 2015 and 2014

Revenue

Revenue was $216.4 million for the year ended January 31, 2015, compared to $124.2 million for the year ended January 31, 2014, representing an increase of $92.2 million, or 74%. The increase in revenue was substantially driven by an increase in subscription services. The increase in subscription services was due to the addition of new customers, as the number of paying organizations increased by 35% from January 31, 2014 to January 31, 2015. Also in this period, we experienced increased renewals from and expansion within existing customers as they broadened their deployment of our product offerings, as reflected in our retention rate of 126% as of January 31, 2015.

Cost of Revenue

Cost of revenue was $47.3 million, or 22% of revenue, for the year ended January 31, 2015, compared to $26.0 million, or 21% of revenue, for the year ended January 31, 2014, representing an increase of $21.2 million, or 82%. The increase in absolute dollars was primarily due to an increase of $8.3 million in depreciation of our server equipment and an increase of $7.2 million in datacenter service costs as we brought our Las Vegas datacenter online and increased our capacity to serve a larger number of customers. In addition, there was an increase of $6.3 million in employee and related costs resulting from headcount growth in our datacenter operations, customer support and professional services functions. Headcount in these functions grew from 116 employees as of January 31, 2014 to 168 employees as of January 31, 2015.

Table of Contents

Research and Development

Research and development expenses were $66.4 million, or 31% of revenue, for the year ended January 31, 2015, compared to $46.0 million, or 37% of revenue, for the year ended January 31, 2014, representing an increase of $20.4 million, or 44%. The increase in absolute dollars was primarily driven by an increase of $9.9 million in employee and related costs and an increase of $8.6 million in stock-based compensation expense as we increased our headcount from 234 employees as of January 31, 2014 to 253 employees as of January 31, 2015 to support continued investment in our product and service offerings and scalability, and an increase of $2.0 million in allocated overhead costs. Research and development expenses as a percentage of revenue decreased 6 points year-over-year as we saw the benefits of our cumulative investment over several years in research and development efforts. We will continue investing in new features and functionality across security, mobility, and industry specific solutions.

Sales and Marketing

Sales and marketing expenses were $207.7 million, or 96% of revenue, for the year ended January 31, 2015, compared to $171.2 million, or 138% of revenue, for the year ended January 31, 2014, representing an increase of $36.6 million, or 21%. The increase in absolute dollars was primarily due to an increase of $10.0 million in employee and related costs and an increase of $6.6 million in stock-based compensation expense, as we increased our headcount from 513 employees as of January 31, 2014 to 570 employees as of January 31, 2015, an increase of $9.1 million in datacenter and customer support costs to support free users, an increase of $3.5 million in advertising expenses, an increase of $2.7 million in allocated overhead costs, and an increase of $1.9 million in travel-related costs. Sales and marketing expenses as a percentage of revenue decreased 42 points year over year due to improved marketing efficiency as our sales and marketing expenses are generally higher for acquiring new customers versus expansions or renewals of existing customer subscriptions. Over time, as our existing customer base grows and a relatively higher percentage of our revenue is attributable to renewals versus new or expanding Box deployments, we expect that sales and marketing expenses will decrease as a percentage of revenue. We continue to invest aggressively to capture our large market opportunity and capitalize on our competitive position, while growing our productivity and efficiency to achieve our long-term margin objectives.

increase of $21.8 million, or 55%. The increase in absolute dollars was primarily due to an increase of $11.5 million in litigation expenses and settlement costs and an increase of $9.9 million in employee and related costs resulting from headcount growth from 109 employees as of January 31, 2014 to 167 employees as of January 31, 2015.

Remeasurement of Redeemable Convertible Preferred Stock Warrant Liability

Remeasurement of redeemable convertible preferred stock warrant liability decreased by $8.6 million during the year ended January 31, 2015 compared to the year ended January 31, 2014. The decrease was primarily due to the exercise of certain warrants to purchase our redeemable convertible preferred stock in January 2014.

Interest Expense, Net and Other Income (Expense), Net

Interest expense, net decreased by $1.7 million, or 46%, during the year ended January 31, 2015 compared to the year ended January 31, 2014. The decrease was primarily due to the end-of-term and early payment fees in connection with the payoff of prior borrowings recognized during year ended January 31, 2014.

Other income (expense), net consisted primarily of foreign currency gains (losses).

Provision (Benefit) for Income Taxes

The decrease in benefit for income taxes during the year ended January 31, 2015 compared to the year ended January 31, 2014 was primarily due to a smaller discrete tax benefit recognized from the release of our valuation allowance in connection with acquisitions. In connection with our fiscal 2015 acquisitions, a deferred tax liability was established for the book-tax basis difference related to acquired intangible assets. The net deferred tax liability from acquisitions provided an additional source of income to support the realizability of our pre-existing deferred tax assets.

The increase in revenue was substantially driven by an increase in subscription services. The increase in subscription services was due to the addition of new customers, as the number of paying organizations increased by 44% from January 31, 2013 to January 31, 2014. Also in this period, we experienced increased renewals from and expansion within existing customers as they broadened their deployment of our product offerings, as reflected in our retention rate of 136% as of January 31, 2014.

The increase in absolute dollars was primarily due to an increase of $45.5 million in employee and related costs, including higher commission expenses of $16.0 million, driven by headcount growth from 374 employees as of January 31, 2013 to 513 employees as of January 31, 2014, and higher sales, an increase of $12.6 million in datacenter and customer support costs to support free users, an increase of $6.4 million in allocated overhead costs, and an increase of $2.8 million in travel-related costs. Sales and marketing expenses as a percentage of revenue decreased 31 points year over year due to improved sales and marketing efficiency as our sales and marketing expenses are generally higher for acquiring new customers versus expansions or renewals of existing customer subscriptions.

Interest expense, net increased by $1.9 million, or 110%, during the year ended January 31, 2014 compared to the year ended January 31, 2013.

Provision (Benefit) for Income Taxes

The decrease in provision (benefit) for income taxes during the year ended January 31, 2014 compared to the year ended January 31, 2013 was primarily due to a discrete tax benefit from a partial release of the valuation allowance on our deferred tax assets, primarily in connection with our acquisition of Crocodoc.

The net deferred tax liability provided an additional source of income to support the realizability of pre-existing deferred tax assets.
