RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all other information contained in this prospectus, including our consolidated financial statements and the related notes, before making a decision to invest in our common stock. The risks and uncertainties described below are not the only ones we face and include risks we consider material of which we are currently aware. If any of the following risks materialize, our business, financial condition, results of operations and prospects could be materially harmed. In that event, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Our Business

If we are unable to attract new users of our services on a cost-effective basis, our business will be materially and adversely affected.

In order to grow our business, we must continue to attract new users on a cost-effective basis. We use and periodically adjust the mix of advertising and marketing programs to promote our services. Significant increases in the pricing of one or more of our advertising channels could increase our advertising costs or may cause us to choose less expensive and perhaps less effective channels to promote our services. As we add to or change the mix of our advertising and marketing strategies, we may need to expand into channels with significantly higher costs than our current programs, which could materially and adversely affect our results of operations. We will incur advertising and marketing expenses in advance of when we anticipate recognizing any revenue generated by such expenses, and we may fail to experience an increase in revenue or brand awareness as a result of such expenditures. We have made in the past, and may make in the future, significant expenditures and investments in new advertising campaigns, and we cannot assure you that any such investments will lead to the cost-effective acquisition of additional customers. New users are drawn to our products and services by rankings circulated by organizations such as Amazon.com, Apple and Google app stores and highly regarded publications such as PC Magazine . If we are unable to maintain effective advertising programs and garner favorable rankings, our ability to attract new customers could be materially and adversely affected, our advertising and marketing expenses could increase substantially, and our results of operations may suffer.

We market our products and services principally to small businesses and households. Many of these consumers tend to be less technically knowledgeable and may be resistant to new technologies such as our cloud-based communications solutions and our connected services. Because our potential customers need to connect additional hardware at their location and take other technical steps not required for the use of traditional communications services such as telephone, fax and e-mail, these consumers may be reluctant to use our service. These customers may also lack sufficient resources, financial or otherwise, to invest in learning about our services, and therefore may be unwilling to adopt them. If these consumers choose not to adopt our services, our ability to grow our business will be limited.

Our customers may terminate their subscriptions for our service at any time without penalty, and increased customer turnover, or costs we incur to retain our customers and encourage them to add users and, in the future, to purchase additional functionalities and premium service editions, could materially and adversely affect our financial performance.

Our customers generally do not have long-term contracts with us, and they may terminate their subscription for our service at any time without penalty or early termination charges. We cannot accurately predict the rate of customer terminations or average monthly service cancellations or failures to renew, which we refer to as churn. Our Ooma Office customers may choose to reduce the number of lines or remove some of the solutions to which they subscribe. Additionally, our Ooma Telo customers subscribing to Premium Services have no obligation to renew their subscriptions for such services and may elect to terminate their subscription for any number of reasons, including changes in financial or employment status, perceived reduction in quality or value, and other unique and personal reasons.

We may not be able to predict the renewal rates for our customers. In addition, small business customers generally pay more for their subscriptions than home or mobile customers, so any increased churn in small business customers could materially and adversely affect our financial performance and user churn, resulting in a significant impact on our results of operations, and an increase in the cost we incur in our efforts to retain our customers and encourage them to upgrade their services and increase their number of users. Our core user churn rate could increase in the future if customers are not satisfied with our service, the value proposition of our services or our ability to otherwise meet their needs and expectations. Churn and reductions in the number of users for whom a small business customer subscribes may also increase due to factors beyond our control. Because of churn and reductions in the number of users for whom a customer subscribes, we have to acquire new customers, or acquire new users within our existing customer base, on an ongoing basis simply to maintain our existing level of customers and revenue. If a significant number of customers terminate, reduce or fail to renew their subscriptions, we may need to incur significantly higher marketing expenditures than we currently anticipate in order to increase the number of new customers or to sell existing customers additional services, and such additional marketing expenditures could harm our business and results of operations. Different factors may affect the churn of business, home, and mobile customers, and Talkatone customers differently. As a result, our business is susceptible to a broad array of market forces, and any of our efforts to mitigate risk of customer churn due to one factor may divert management’s time and focus away from efforts to mitigate risk of customer churn due to other factors. This broad-based susceptibility to churn could materially and adversely affect our financial performance.

Our future success also depends in part on our ability to sell additional subscriptions and additional functionalities to our current customers. This may require increasingly sophisticated and more costly sales efforts and a longer sales cycle. Any increase in the costs necessary to upgrade, expand and retain existing customers could materially and adversely affect our financial performance. If our efforts to convince customers to add users and, in the future, to purchase additional functionalities are not successful, our business may suffer. In addition, such increased costs could cause us to increase our subscription rates, which could increase our turnover rate.

We face intense competition in our markets by our competitors and may lack sufficient financial or other resources to compete successfully.

The cloud-based communications and connected services industries are highly competitive. We face continued intense competition from (i) established communications providers, such as AT&T Inc., Comcast Corporation and Verizon Communications Inc. in the U.S., and Rogers Communications Inc. and others in Canada; (ii) other communications companies such as 8x8, Inc., magicJack VocalTec Ltd., RingCentral, Inc. and Vonage Holdings Corp.; (iii) companies such as Broadsoft, Inc. and Microsoft Corporation (that generally license their software) and their resellers; (iv) traditional on-premise, hardware communications providers, such as Avaya Inc., Cisco Systems, Inc., ShoreTel, Inc. and their resellers; (v) mobile communications app companies providing “over-the-top” solutions, such as LINE Corporation, Pinger, Inc., Viber Media S.à.r.l. and WhatsApp Inc.; and (vi) other large internet companies, such as Google Inc. All of these companies currently or may in the future host their solutions through the cloud. In addition, as we expand our connected services, we face competition from lead-generation and internet search engine optimization companies and home automation companies.

Aggressive business tactics by our competitors may reduce our revenue.

Increased competition may result in aggressive business tactics by our competitors, including:

15

Table of Contents

Our retail partners may offer the products and services of competing companies, which would adversely affect our business. Competition from other companies may also adversely affect our negotiations with service providers and suppliers, including, in some cases, requiring us to lower our prices. We may not be able to compete successfully with the offerings and sales tactics of other companies, which could result in the loss of customers and, as a result, our revenue and profitability could be adversely affected.

Mergers or other strategic transactions involving our competitors could weaken our competitive position, which could adversely affect our ability to compete effectively and harm our results of operations; additionally, mergers or other strategic transactions we engage in may not be successful.

We believe that some of our existing competitors may consolidate or be acquired. In addition, some of our competitors may enter into new alliances with each other or may establish or strengthen cooperative relationships with systems integrators, third-party consulting firms or other parties. Any such consolidation, acquisition, alliance or cooperative relationship could adversely affect our ability to compete effectively and lead to pricing pressure and our loss of market share, and could result in a competitor with greater financial, technical, marketing, service and other resources, all of which could harm our business, results of operations and financial condition.

In the past we have decided, and in the future may decide, to enter into mergers or other strategic transactions in which we acquire other companies. We cannot guarantee we will be able to successfully integrate the teams, assets, or business of these target companies into our business, that we will be able to fully recover the costs of such transactions or that we will be successful in leveraging such strategic transactions into increased business for our products.

We rely significantly on retailers and reseller partnerships to sell our products; our failure to effectively develop, manage, and maintain our retail sales and reseller partnership channels could materially and adversely affect our revenue.

We currently sell our Ooma Telo and Ooma Office products through a combination of direct sales, leading retailers such as Amazon.com, Costco.com, Best Buy, Fry’s Electronics, Future Shop and Walmart, and our reseller partnership with Vivint Inc., and a significant portion of our product sales are made through our retail and reseller partnership channels. Similarly, to date, the vast majority of our Business Promoter accounts are obtained through a limited number of reseller partnerships. In addition, our Talkatone division relies significantly on the Apple and Google app stores for distribution. Our future success depends on our continued ability to establish and maintain a network of productive retailers, to maintain and expand our reseller partnership arrangements, and to maintain the ability of Talkatone to be distributed through the app stores and increase Talkatone’s visibility therein. We expect that we will need to maintain and expand our retail channel and reseller partnership sales and Talkatone’s distribution and visibility in the app stores as we seek to expand our customer base. We generally do not have long-term contracts with our retailers, distributors and reseller partners, and we have in the past and may in the future experience a loss of or reduction in sales through any of these third parties, which could materially reduce our revenue . In addition, if Apple or Google determine that Talkatone is non-compliant with their app store vendor policies, they may revoke our rights to sell Talkatone through their app store at any time. Our competitors may in some cases be effective in causing our current and potential retailers, and reseller partners to favor their services or prevent or reduce sales of our services. If we fail to maintain relationships with current retailers and reseller partners, fail to develop relationships with new retailers and reseller partners in new markets or expand the number of retailers and reseller partners in existing markets, or if we fail to manage, train, or provide appropriate incentives to our existing retailers and reseller partners, or if they are not successful in their sales efforts, sales of our products and services may decrease and our results of operations would suffer.

We depend on four vendors to manufacture the on-premise appliances and end-point devices we sell, and any delay or interruption in manufacturing, configuring and delivering by these third parties would result in delayed or reduced shipments to our customers and may harm our business.

We primarily rely on Mitac Computing Technology Corporation and Kentec Technology (SUZHOU) Co., Ltd. for production of our on-premise appliances and primarily on Hualin Precision Technology Co., Ltd and VTech Telecommunication Ltd. for production of our end-point devices we sell to our customers. We currently do not have long-term contracts with these vendors. As a result, these third parties are not obligated to provide products to or perform services for us for any specific period, in any specific quantities or at any specific price, except as may be provided in a particular purchase order. If these third parties are unable to deliver on-premise appliances or end-point devices of acceptable quality or in a timely manner, our ability to bring services to market, the reliability of our services and our reputation could suffer. We expect that it could take several months to effectively transition to new third-party manufacturers or fulfillment agents. Additionally, several components used in our on-premise appliances and end point devices are “single sourced” and any interruption in the suppliers of such components could cause our business to suffer as we identify alternative sources of components. Due to the recent West Coast port strikes, we experienced delayed shipments of our products from our manufacturers. Future repetition of such delays could negatively affect our ability to deliver product to our customers in a timely manner and may harm our business and hinder our growth.

To deliver our services, we rely on third parties for our network connectivity and co-location facilities for certain features in our services and for certain elements of providing our services.

We currently use the infrastructure of third-party service providers for hosting, internet access and other services that are vital to our service offering. Equinix, Inc. provides data center facilities; Internap, Zao and NTT Inc. provide backbone internet access; and Bandwidth.com, Onvoy, Level 3, Broadvox and EarthLink provide origination services. We also rely on third-party services for our SMS and speech-to-text services which are sole-sourced. Intrado is our sole provider of 911 services. We expect that we will continue to rely heavily on third-party network service providers to provide these services for the foreseeable future. If any of these network service providers stop providing us with access to their infrastructure, fail to provide these services to us on a cost-effective basis, cease operations, or otherwise terminate these services, the delay caused by qualifying and switching to another third-party network service provider, if one is available, could have a material adverse effect on our business and results of operations.

We may be required to transfer our servers to new data center facilities if we are unable to renew our leases on acceptable terms, if at all, or the owners of the facilities decide to close their facilities, and we may incur significant costs and possible service interruption in connection with doing so. In addition, any financial difficulties, such as bankruptcy or foreclosure, faced by our third-party data center operators or any of the service providers with which we or they contract, may have negative effects on our business, the nature and extent of which are difficult to predict. Additionally, if our data centers are unable to keep up with our increasing needs for capacity, our ability to grow our business could be materially and adversely impacted.

If problems occur with any of these third-party network or service providers, it may cause errors or reduced quality in our services, and we could encounter difficulty identifying the source of the problem. The occurrence of errors or reduced quality in our service, whether caused by our systems or a third-party network or service provider, may result in the loss of our existing customers, delay or loss of market acceptance of our services, termination of our relationships and agreements with our resellers or liability for failure to meet service level agreements, and may seriously harm our business and results of operations.

We rely on purchased or leased hardware and software licensed from third parties in order to offer our service. In some cases, we integrate third-party licensed software components into our platform. This hardware and software may not continue to be available at reasonable prices or on commercially reasonable terms, or at all. Any loss of the right to use any of this hardware or software could significantly increase our expenses and

17

Table of Contents

otherwise result in delays in the provisioning of our service until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated. Any errors or defects in third-party hardware or software could result in errors or a failure of our service which could harm our business.

We also contract with third parties to provide enhanced 911, or E-911, services, including assistance in routing emergency calls and terminating E-911 calls. Our providers operate a national call center that is available 24 hours a day, seven days a week, to receive certain emergency calls and maintain public service answering point, or PSAP, databases for the purpose of deploying and operating E-911 services. On mobile devices, we generally rely on the underlying cellular or wireless carrier to provide E-911 services. Any failure to perform, including interruptions in service, by our vendors, could cause failures in our customers’ access to E-911 services and expose us to significant liability and damage our reputation.

Interruptions in our services could harm our reputation, result in significant costs to us and impair our ability to sell our services.

Because our technology platform is complex, incorporates a variety of new computer hardware, and the platform continues to evolve, our services may have errors or defects that are identified after customers begin using such services, which could result in unanticipated service interruptions. Although we test our services to detect and correct errors and defects before their initial release and before we make updates or other changes to such services, we have occasionally experienced significant service interruptions as a result of undetected errors or defects and may experience future interruptions of service if we fail to detect and correct errors and defects. For example, in April and May 2015 while working to upgrade our network, we encountered unexpected problems with the communications between our data centers, as well as certain server capacity issues, which led to multiple intermittent service outages, some of which lasted for up to approximately eight hours for some of our customers. While we have identified root causes of these service outages, and in each case were able to restore service to all of the affected customers, we continue to take corrective actions to address these root causes. We were able to correct such root causes without incurring material expenses, and we do not expect the outages in April and May to materially affect our results of operations. However, the costs incurred in correcting root causes for future service outages may be substantial and these and other related consequences could negatively impact our results of operations.

We currently serve our customers from two data center hosting facilities located in Northern California, where we lease space from Equinix, Inc. The second data center in Northern California was added in early 2015, and while we believe that such second data center and certain new procedures we have adopted will enable us to restore services quickly in the event of a service outage, these new procedures and our second data center, by themselves, will not prevent future outages. Any damage to, or failure of, these facilities, the communications network providers with whom we or they contract or with the systems by which our communications providers allocate capacity among their customers, including us, could result in interruptions in our service. Additionally, in connection with the expansion or consolidation of our existing data center facilities, we may move or transfer our data and our customers’ data to other data centers. Despite precautions we take during this process, any unsuccessful data transfers may impair or cause disruptions in the delivery of our service.

Despite precautions taken at our hosting facilities, the occurrence of a natural disaster or an act of terrorism or other unanticipated problems at these facilities could result in lengthy interruptions in our service. Even with the disaster recovery arrangements that we have in place, our service could be interrupted.

Any defects in, or unavailability of, the components of our platform that cause interruptions of our services could, among other things:

We rely on third parties for some of our software development, quality assurance and operations.

We currently depend on various third parties for some of our software development efforts, quality assurance and operations. Specifically, we outsource some of our software development and design, quality assurance and operations activities to third-party contractors that have employees and consultants located in Canada, India, China, New Zealand, Russia and Ukraine. Our dependence on third-party contractors creates a number of risks, in particular, the risk that we may not maintain control or effective management with respect to these business operations.

Our agreements with these third-party contractors are either not terminable by them (other than at the end of the term or upon an uncured breach by us) or require at least 30 days’ prior written notice of termination. If we experience problems with our third-party contractors, the costs charged by our third-party contractors increase or our agreements with our third-party contractors are terminated, we may not be able to develop new solutions, enhance or operate existing solutions or provide customer support in an alternate manner that is equally or more efficient and cost-effective.

We anticipate we will continue to depend on these and other third-party relationships in order to grow our business for the foreseeable future. If we are unsuccessful in maintaining existing and, if needed, establishing new relationships with third parties, our ability to efficiently operate existing services or develop new services and provide adequate customer support could be impaired, and as a result, our competitive position or our results of operations could suffer.

We rely on third parties to provide the majority of our customer service and support representatives. If these third parties do not provide our customers with reliable, high-quality service, our reputation will be harmed, and we may lose customers.

We offer customer support through both our online account management website and our toll-free customer support number. Our customer support is currently provided via a third-party provider located in the Philippines, as well as our employees in the U.S. We currently offer support almost exclusively in English. Our third-party providers generally provide customer service and support to our customers without identifying themselves as independent parties. The ability to support our customers may be disrupted by natural disasters, inclement weather conditions, civil unrest, strikes, acts of terrorism and other adverse events in the Philippines. Furthermore, as we expand our operations internationally, we may need to make significant expenditures and investments in our customer service and support to adequately address the complex needs of international customers, such as support in multiple foreign languages.

If any of these third parties do not provide reliable, high-quality service, our reputation and our business will be harmed and we may be exposed to significant liability. In addition, a significant service outage may cause a high volume of customer support inquiries, and our third-party customer service call center might be unable to respond to a significant spike in customer support inquiries in a timely manner. In addition, industry consolidation among providers of services to us may impact our ability to obtain these services or increase our costs for these services.

Our limited operating history makes it difficult to evaluate our current business and future prospects, which may increase the risk of investing in our stock.

Although we were incorporated in 2003, we did not formally introduce Ooma Telo until 2009 or Ooma Office until 2013. In addition, we acquired our Business Promoter business in 2012 and our Talkatone business in 2014. Our limited operating history limits our ability to plan for and model future growth. We have encountered and expect to continue encountering risks and uncertainties frequently experienced by growing companies in rapidly changing markets. If our assumptions regarding these uncertainties are incorrect or change in reaction to changes in our markets, or if we do not manage or address these risks successfully, our results of operations could differ materially from our expectations, and our business could suffer. Any success we may experience in the future will depend, in large part, on our ability to, among other things:

We have incurred significant losses and negative cash flows in the past and anticipate continuing to incur losses and negative cash flows for the foreseeable future, and we may therefore not be able to achieve or sustain profitability in the future.

We have incurred substantial net losses since our inception, including net losses of approximately $(3.7) million, $(2.0) million and $(6.4) million for fiscal 2013, fiscal 2014 and fiscal 2015, respectively, and a net loss of $(3.9) million for the three months ended April 30, 2015. We had an accumulated deficit of $(54.7) million as of April 30, 2015. We have spent considerable amounts of time and money since inception to develop new communications solutions and connected services. Additionally, we have incurred substantial losses and expended significant resources to market, promote, develop and sell our products and solutions. We also expect to continue investing for future growth, including for advertising, customer acquisition, technology infrastructure, storage capacity, services development and international expansion. In addition, as a public company, we will incur significant additional accounting, legal and other expenses.

20

Table of Contents

As a result of our increased expenditures, we will have negative operating cash flows for the foreseeable future and will have to generate and sustain increased revenue to achieve future profitability. Achieving profitability will require us to increase revenue, manage our cost structure and avoid significant liabilities. Revenue growth may slow, revenue may decline or we may incur significant losses in the future for a number of possible reasons, including general macroeconomic conditions, increasing competition (including competitive pricing pressures), a decrease in the growth of the markets in which we compete or failure for any reason to continue capitalizing on growth opportunities. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays, service delivery and quality problems and other unknown factors that may result in losses in future periods. If these losses exceed our expectations or our revenue growth expectations are not met in future periods, our financial performance will be harmed and our stock price could be volatile or decline.

Our business could suffer if we cannot obtain or retain direct inward dialing numbers, or DIDs, are prohibited from obtaining local or toll-free numbers, or are limited to distributing local or toll-free numbers to only certain customers.

Our future success depends on our ability to procure large quantities of local and toll-free DIDs in the U.S. and foreign countries in desirable locations at a reasonable cost and without restrictions. Our ability to procure and distribute DIDs depends on factors outside of our control, such as applicable regulations, the practices of the communications carriers that provide DIDs, the cost of these DIDs, and the level of demand for new DIDs. Due to their limited availability, there are certain popular area code prefixes we generally cannot obtain. Our inability to acquire DIDs for our operations would make our services less attractive to potential customers in the affected local geographic areas. In addition, future growth in our customer base, together with growth in the customer bases of other providers of internet-based business communications, has increased, which increases our dependence on needing sufficiently large quantities of DIDs.

If we are unable to effectively process local number and toll-free number portability provisioning in a timely manner, our growth may be negatively affected.

We support local number and toll-free number portability, which allows our customers to transfer to us and thereby retain their existing phone numbers when subscribing to our small business, home, and mobile services. Transferring numbers can be a manual process that can take up to 15 business days or longer to complete. A new customer of our services must maintain both our service and the customer’s existing phone service during the number transferring process. Any delay we experience in transferring these numbers typically results from the fact that we depend on third-party carriers to transfer these numbers, a process we do not control, and these third-party carriers may refuse or substantially delay the transfer of these numbers to us. Local number portability is considered an important feature by many potential customers, and if we fail to reduce any related delays, we may experience increased difficulty in acquiring new customers. Moreover, the FCC requires us to comply with specified number porting timeframes when customers leave our service for the services of another provider. In Canada, the Canadian Radio-television and Telecommunications Commission, or CRTC, has imposed a similar number portability requirement on service providers like us. If we, or our third-party carriers, are unable to process number portability requests within the requisite timeframes, we could be subject to fines and penalties. Additionally, in the U.S., both customers and carriers may seek relief from the relevant state public utility commission, the FCC, or in state or federal court for violation of local number portability requirements.

If small businesses opt to perform advertising tasks on their own, demand for our lead-generation services would decrease, thereby negatively affecting our revenue.

Large internet marketing providers such as Google, Yahoo! and Microsoft offer online advertising products to small businesses through self-service platforms. As small businesses become more familiar with such platforms, they may increasingly choose to actively manage their own internet presence and their demand for the lead-generation services may decrease. We cannot predict the evolving experiences and preferences of small

21

Table of Contents

businesses and cannot assure you that we can develop our lead generation business, or develop similar new services, in a manner that will suit their needs and expectations faster or more effectively than our competitors, or at all. If we are not able to do so, our results of operations would suffer.

Our access to the majority of our lead-generation customers is currently through a limited number of digital agencies, which creates a significant risk that we could lose a majority of our lead generation service customers due to factors beyond our control.

We currently contract with five digital agencies to provide our lead-generation services as a component of their service to third parties who we include as our core users. If our relationship with these digital agencies degrades, they could elect not to use our lead-generation service, which would lead to the loss of a portion of our lead generation business revenue as well as a number of our core users. Also, for reasons beyond our control, the digital agencies we work with may lose their business relationships with third parties who purchase lead generation services for their customers, causing the digital agency to terminate its business relationship with us and the loss of such lead generation business revenue. Prior to February 2015, we contracted with three digital agencies to provide our lead generation service to third parties. In February 2015, one of them unexpectedly lost a key business relationship, which led that digital agency to terminate its business relationship with us, which in turn caused us to lose a few thousand of our core users. This concentration of our access to lead generation customers creates volatility in the churn of our core users, which risk will remain unless and until we significantly grow the number of digital agencies we contract with, and/or increase the number of small businesses that obtain lead generation services directly from us.

If we fail to continue developing our brand or our reputation is harmed, our business may suffer.

We believe that continuing to strengthen our current brand will be critical to achieving widespread acceptance of our services and will require continued focus on active marketing efforts. The demand for and cost of online and traditional advertising have been increasing and may continue to increase. Accordingly, we may need to increase our investment in, and devote greater resources to, advertising, marketing, and other efforts to create and maintain brand loyalty among users. Brand promotion activities may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses incurred in building our brands. If we fail to promote and maintain our brand, or if we incur substantial expense in an unsuccessful attempt to promote and maintain our brands, our business could be materially and adversely affected.

Our services, as well as those of our competitors, are regularly reviewed and commented upon by online and social media sources, as well as computer and other business publications. Negative reviews, or reviews in which our competitors’ products and services are rated more highly than our solutions, could negatively affect our brand and reputation. From time to time, our customers have expressed dissatisfaction with our services, including dissatisfaction with our customer support, our billing policies and the way our services operate. If we do not handle customer complaints effectively, our brand and reputation may suffer, we may lose our customers’ confidence, and they may choose to terminate, reduce or not to renew their subscriptions. In addition, many of our customers participate in social media and online blogs about internet-based services, including our services, and our success depends in part on our ability to minimize negative and generate positive customer feedback through such online channels where existing and potential customers seek and share information. If actions we take or changes we make to our services upset these customers, their blogging could negatively affect our brand and reputation. Complaints or negative publicity about our services or customer service could materially and adversely impact our ability to attract and retain customers and our business, financial condition and results of operations.

A security breach could delay or interrupt service to our customers, compromise the integrity of our systems or data that we collect, result in the loss of our intellectual property or confidential information, harm our reputation, or subject us to significant liability.

Our operations depend on our ability to protect our network from interruption or damage resulting from unauthorized access or entry, computer viruses or malware or other events beyond our control. In the past, we

22

Table of Contents

may have been subject to undetected distributed denial-of-service, or DDOS, cyberattacks by hackers intent on bringing down our services, and we may be subject to DDOS and other forms of cyberattacks in the future. We cannot assure you that our backup systems, regular data backups, physical, technological and organizational security protocols and measures and other procedures that are currently in place, or that may be in place in the future, will be adequate to prevent unauthorized access to our systems, significant damage, system interruption, degradation or failure, or data loss or to respond to a cyberattack once launched. Additionally, hackers may attempt to directly gain access to a customer’s on-premise appliance, which may delay or interrupt services, or may subject our customers to further security risks, including in relation to any connected household devices a customer might have now or in the future, such as Nest devices or other household sensors, or to our network more generally. Also, our services are web-based, and the amount of data we store for our users on our servers has been increasing as our business has grown. Despite the implementation of security measures, our infrastructure may be vulnerable to hackers, computer viruses, worms, other malicious software programs or similar disruptive problems caused by our customers, employees, consultants or other internet users who attempt to invade public and private data networks. In some cases we do not have in place disaster recovery facilities for certain ancillary services, such as email delivery of messages. Currently, nearly all of our customers authorize us to bill their credit or debit card accounts directly for all transaction fees that we charge. We rely on encryption and authentication technology to ensure secure transmission of confidential information, including customer credit and debit card numbers. Despite our efforts to encrypt and secure customer payment card information, hackers with sufficiently sophisticated technology or methods may still be able to infiltrate our systems to gain unauthorized access to payment card information. Further, advances in computer capabilities, new discoveries in the field of cryptography or other developments may result in a compromise or breach of the technology we use to protect transaction data.

Additionally, third parties may attempt to fraudulently induce domestic and international employees, consultants or customers into disclosing sensitive information, such as user names, passwords or customer proprietary network information, or CPNI, or other information in order to gain access to our customers’ data or to our data. CPNI includes information such as the phone numbers called by a customer, the frequency, duration, and timing of such calls, and any services purchased by the customer, such as call waiting, call forwarding and caller ID, in addition to other information that may appear on a customer’s bill. Third parties may also attempt to fraudulently induce employees, consultants or customers into disclosing sensitive information regarding our intellectual property and other confidential business information, or our information technology systems. In addition, because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any system failure or security breach that causes interruptions or data loss in our operations or in the computer systems of our customers or leads to the misappropriation of our or our customers’ confidential or personal information, or CPNI, could result in significant liability to us. Such failure or breach could cause our service to be perceived as not being secure, subject us to regulatory requirements such as FCC notification, result in significant monetary costs, such as fines, legal fees and expenditures to improve and enhance our security measures, cause considerable harm to us and our reputation (including requiring notification to customers, regulators or the media) and deter current and potential customers from using our services. Additionally, we could incur significant costs, both monetary and with respect to management’s time and attention, to investigate and remediate a data security breach. Because our onboarding and billing functions are conducted through a single data center, any security breach in that data center may cause an interruption in our business operations. Any of these events could have a material adverse effect on our business, results of operations and financial condition.

Failures in internet infrastructure or interference with broadband access could cause current or potential customers to believe that our systems are unreliable, leading our current customers to switch to our competitors or potential customers to avoid using our services.

Many of our services depend on our customers’ broadband access to the internet, usually provided through a cable or digital subscriber line, or DSL, connection. In addition, users who access our services and applications

Table of Contents

through mobile devices, such as smartphones and tablets, must have a high-speed connection, such as Wi-Fi, 3G, 4G or LTE, to use our services and applications. Currently, this access is provided by companies that have significant and increasing market power in the broadband and internet access marketplace, including incumbent phone companies, cable companies and wireless companies. Increasing numbers of users and increasing bandwidth requirements may degrade the performance of internet and mobile infrastructure, resulting in outages or deteriorations in connectivity and negatively impacting the quality with which we can deliver our solutions. As our customer base grows and their usage of communications capacity increases, we will be required to make additional investments in network capacity to maintain adequate data transmission speeds, the availability of which may be limited, or the cost of which may be on terms unacceptable to us. If adequate capacity is not available to us as our customers’ usage increases, our network may be unable to achieve or maintain sufficiently high data transmission capacity, reliability or performance. Furthermore, as the rate of adopting new technologies increases, the networks on which our services and applications rely may not be able to sufficiently adapt to the increased demand for these services, including ours. In the past, we have experienced disruptions to our service. For example, in August 2011, we experienced an outage for approximately three hours, and in April and May 2015, we experienced multiple intermittent service outages that lasted for up to eight hours for some of our customers. Frequent or persistent interruptions could cause current or potential users to believe that our systems or services are unreliable, leading them to switch to our competitors or to avoid our services, and could permanently harm our reputation and brands. Because some of our services rely on integration between features that use both wired and wireless infrastructures, any of the aforementioned problems with either wired or wireless infrastructure may result in the inability of customers to take advantage of our integrated services and therefore may decrease the attractiveness of our collective services to current and potential customers.

The success of our business relies on customers’ continued and unimpeded access to broadband service. Providers of broadband services may be able to block our services or charge their customers more for using our services, which could adversely affect our revenue and growth.

Some of the providers of broadband internet access and high-speed mobile access, such as AT&T and Verizon, offer products and services that directly compete with our own offerings, which can potentially give such providers a competitive advantage. For example, these providers may market and sell a bundle of services to our current and potential customers that includes services directly competitive to ours, and our current and potential customers may prefer these bundled offerings. Some providers of broadband access, including providers outside of the U.S., may take measures that affect their customers’ ability to use our service, such as degrading the quality of the data packets we transmit over their lines, giving those packets low priority, giving other packets higher priority than ours, blocking our packets entirely or attempting to charge their customers more for also using our services. While actions like these by U.S. providers would violate the net neutrality rules recently adopted by the FCC and described below, most foreign countries have not adopted formal net neutrality or open internet rules, and there continues to be some uncertainty regarding whether the net neutrality rules will be upheld by courts or modified by legislative action.

On March 12, 2015 the FCC released new network neutrality and open internet rules that it had adopted on February 26, 2015. In that order, the FCC reclassified broadband Internet access services as a telecommunications service subject to some elements of common carrier regulation, including the obligation to provide service on just and reasonable terms, requirements related to customer privacy and requirements for accessibility for people with disabilities. The order also prohibits blocking or discriminating against lawful services and applications and prohibits “paid prioritization,” or providing faster speeds or other benefits in return for compensation. The order does not go into effect until June 12, 2015 and is the subject of pending appeals by several parties. The net neutrality rules could affect the market for broadband internet access service in a way that impacts our business, for example by increasing the cost of broadband internet service and thereby depressing demand for our services or by increasing the costs of services we purchase.

Our quarterly and annual results of operations have fluctuated in the past and may continue to do so in the future. As a result, we may fail to meet or to exceed the expectations of research analysts or investors, which could cause our stock price to fluctuate.

Our quarterly and annual results of operations have varied historically from period to period, and we expect that they will continue to fluctuate due to a variety of factors, many of which are outside of our control, including:

Any one of the factors above, or the cumulative effect of some or all of the factors referred to above, may result in significant fluctuations in our quarterly and annual results of operations. This variability and unpredictability could result in our failure to meet our internal operating plan or the expectations of securities analysts or investors for any period, which could cause our stock price to decline. In addition, a significant percentage of our operating expenses is fixed in nature and is based on forecasted revenue trends. Accordingly, in the event of revenue shortfalls, we may not be able to mitigate the negative impact on net income (loss) and margins in the short term. If we fail to meet or exceed the expectations of research analysts or investors, the market price of our shares could fall substantially and we could face costly lawsuits, including securities class-action suits.

We may require additional capital to pursue our business objectives and to respond to business opportunities, challenges or unforeseen circumstances. If capital is not available to us or only under unfavorable terms, our business, results of operations and financial condition may be adversely affected.

We intend to continue making expenditures and investments to support the growth of our business and may require additional capital to pursue our business objectives and respond to business opportunities, challenges or unforeseen circumstances, including the need to develop new solutions or enhance our existing solutions, enhance our operating infrastructure, and acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. However, additional funds may not be available

25

Table of Contents

when we need them on terms acceptable to us, or at all. Our credit agreements with Silicon Valley Bank include restrictive covenants and any debt financing we secure in the future could involve further restrictive covenants, which may make it more difficult for us to obtain additional capital and to pursue business opportunities.

In addition, volatility in the credit markets may have an adverse effect on our ability to obtain debt financing. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, our ability to continue pursuing our business objectives and to respond to business opportunities, challenges or unforeseen circumstances could be significantly limited, and our business, results of operations, financial condition and prospects could be materially and adversely affected.

We face a risk of non-compliance with certain covenants in our loan agreements with Silicon Valley Bank. If we are unable to meet the financial or other covenants under the agreements or to negotiate future waivers or amendments of the covenants, we could be in default under the agreements.

We have credit agreements with Silicon Valley Bank, or SVB, consisting of (i) a credit facility comprised of a $4.0 million senior secured term loan facility and a $12.0 million senior secured revolving facility, and (ii) a mezzanine facility comprised of a $5.0 million subordinated secured term loan facility and a conditional subordinated secured term loan facility of up to an aggregate of $5.0 million. As of April 30, 2015, we had an aggregate of approximately $10.7 million in outstanding borrowings including accrued interest under these agreements. Our credit agreements with SVB contain customary negative covenants that limit our ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets and merge or consolidate. The SVB facilities are secured by substantially all of our assets, though certain intellectual property collateral may be released if an initial public offering has occurred and no event of default under the SVB credit agreements exists. The SVB credit agreements also contain customary affirmative covenants, including requirements to, among other things, maintain minimum cash balances tied to the maximum commitment amounts outstanding under the SVB credit agreements following any initial public offering, and deliver audited financial statements. Upon the occurrence and during the continuation of an event of default, amounts due under the loan agreement may be accelerated by SVB. If we are unable to meet the financial or other covenants under the credit agreements or negotiate future waivers or amendments of such covenants, an event of default could occur under the credit agreements. Upon the occurrence and during the continuance of an event of default under the credit agreements, SVB has available a range of remedies customary in these circumstances, including declaring all outstanding debt, together with accrued and unpaid interest thereon, to be due and payable, foreclosing on the assets securing the loan agreement and/or ceasing to provide additional credit, which could have a material adverse effect on us. We were in compliance with all of the covenants as of April 30, 2015.

Growth may place significant demands on our management and our infrastructure.

We have recently experienced substantial growth in our business, including an increase in the number of customers we consider to be our core users. This growth has placed and may continue to place significant demands on our management and our operational and financial infrastructure. As our operations grow in size, scope and complexity, we will need to increase our sales and marketing efforts and add additional sales and marketing personnel worldwide and to improve and upgrade our systems and infrastructure to attract, service, and retain an increasing number of users. For example, we expect the volume of simultaneous calls to increase significantly as our user base grows. Our network hardware and software may not be able to accommodate this additional simultaneous call volume. The expansion of our systems and infrastructure will require us to commit substantial financial, operational and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Any such additional capital investments will increase our cost base. Continued growth could also strain our ability to maintain reliable service levels for our users, develop and improve our operational, financial and management controls, enhance our reporting systems

26

and procedures and recruit, train, and retain highly skilled personnel. If we fail to achieve the necessary level of efficiency in our organization as we grow, our business, results of operations, and financial condition could be materially and adversely affected.

Shifts in trends or the emergence of new technologies may render our solutions obsolete or require us to expend significant resources to develop, license, or acquire new services or applications on a timely and cost-effective basis in order to remain competitive.

The cloud-based communications and connected services industries are emerging markets characterized by rapid changes in customer requirements, frequent introductions of new and enhanced services, and continuing and rapid technological advancement. We cannot predict the effect of technological changes on our business. To compete successfully in these emerging markets, we must anticipate and adapt to technological changes and evolving industry standards and continue to design, develop, manufacture and sell new and enhanced services that provide increasingly higher levels of performance and reliability at lower cost. For the fiscal year ended January 31, 2015 and for the three months ended April 30, 2015, we derived approximately 83% and 79%, respectively, of our revenue from Ooma Telo, and we expect Ooma Telo will continue to account for a majority of our revenue for the foreseeable future. However, our future success will also depend on our ability to introduce and sell new services, features and functionality that enhance or are beyond the voice, fax, text and connected services we currently offer, as well as to improve usability and support and increase customer satisfaction. Our failure to develop solutions that satisfy customer preferences in a timely and cost-effective manner may harm our ability to renew our subscriptions with existing customers and to create or increase demand for our services and may materially and adversely impact our results of operations.

The introduction of new services by competitors or the development of entirely new technologies to replace existing offerings could make our solutions obsolete or adversely affect our business and results of operations. Announcements of future releases and new services and technologies by our competitors or by us could cause customers to defer purchases of our existing services, which also could have a material adverse effect on our business, financial condition or results of operations. We may experience difficulties with software development, operations, design or marketing that could delay or prevent our development, introduction or implementation of new or enhanced services and applications. We have in the past experienced delays in the planned release dates of new features and upgrades, and have discovered defects in new services and applications after their introduction. We cannot assure you that new features or upgrades will be released according to schedule, or that, when released, they will not contain defects. Either of these situations could result in adverse publicity, loss of revenue, delay in market acceptance or claims by customers brought against us, all of which could harm our reputation, business, results of operations, and financial condition. Moreover, the development of new or enhanced services or applications may require substantial investment, and we must continue to invest a significant amount of resources in our research and development efforts to develop these services and applications to remain competitive. We do not know whether these investments will be successful. If customers do not widely adopt any new or enhanced services and applications, we may not be able to realize a return on our investment. If we are unable to develop, license or acquire new or enhanced services and applications on a timely and cost-effective basis, or if such new or enhanced services and applications do not achieve market acceptance, our business, financial condition and results of operations may be materially and adversely affected.

Our success depends on the public acceptance of our connected services and applications.

Our future growth depends on our ability to significantly increase revenue generated from our communications solutions and other connected services that integrate voice communications technology with other functions, such as business promotion, automation, security and others. The markets for cloud-based communications and connected services are evolving rapidly and are characterized by an increasing number of market entrants. As is typical of a rapidly evolving industry, the demand for, and market acceptance of, these applications is uncertain. If the markets for cloud-based communications solutions or for other connected services fail to develop, develop more slowly than we anticipate or develop in a manner different than we expect, our services could fail to achieve market acceptance, which in turn could materially and adversely affect our business.

Our future growth in the small business market depends on the continued use of voice communications by businesses, as compared to e-mail and other data-based methods. A decline in the overall rate of voice communications by businesses would harm our business. Furthermore, our continued growth depends on future demand for and adoption of internet voice communications systems and services and on future demand for connected communications services. Although the number of broadband subscribers worldwide has grown significantly in recent years, only a small percentage of businesses have adopted internet voice communications services to date. For demand and adoption of internet voice communications services by businesses to increase, internet voice communications networks must improve the quality of their service for real-time communications by managing the effects of and reducing packet loss, packet delay, and packet jitter, as well as unreliable bandwidth, so that high-quality service can be consistently provided. Additionally, the cost and feature benefits of internet voice communications must be sufficient to cause customers to switch from traditional phone service providers. We must devote substantial resources to educate potential customers about the benefits of internet voice communications solutions, in general, and of our services in particular. If any or all of these factors fail to occur, our business may be materially and adversely affected.

Our Ooma Telo product and services are being sold to individuals and families. With the growth in cellular and other mobile technologies, many consumers have chosen to eliminate altogether their home telephone service. Our ability to continue growing our user base depends on our ability to convince our customers and potential customers that our service is sufficiently useful and cost-effective, such that it makes sense to maintain or reestablish home telephone services with us. Our growth could slow and our financial condition could be adversely affected if the trend of eliminating home telephone service continues or accelerates.

Our mobile platform, available to any consumer with a Wi-Fi or cellular data connected mobile device, operates in a market that is fragmented and difficult to get noticed by consumers. Many of our competitors in this market have been able to establish a significant user base and reputation in the market, which may make it more difficult for our products to be adopted. Furthermore, as new mobile devices are released, we may encounter difficulties supporting these devices and services, and we may need to devote significant resources to the creation, support, and maintenance of our mobile applications. Additionally, our competitors may allocate additional resources to marketing and promotion of their products, making it even more difficult to be noticed. It is also unclear how the adoption of “over-the-top” based communications will continue to grow. If the number of consumers using “over-the-top” based communications stagnates or declines, such movement may result in an intensified competition for consumers in this space.

Accusations of infringement of third-party intellectual property rights could materially and adversely affect our business.

There has been substantial litigation in the areas in which we operate regarding intellectual property rights. In the past, we have been sued by third parties claiming infringement of their intellectual property rights and we may be sued for infringement from time to time in the future. In the past, we have settled infringement litigation brought against us; however, we cannot assure you that we will be able to settle any future claims or, if we are able to settle any such claims, that the settlement will be on terms favorable to us. Our broad range of technology may increase the likelihood that third parties will claim that we infringe their intellectual property rights.

We have in the past received, and may in the future receive, notices of claims of infringement, misappropriation or misuse of other parties’ proprietary rights. For example, on April 17, 2015, plaintiff UrgenSync, LLC filed a complaint in the U.S. District Court for the Eastern District of Texas against us and other companies in the business of providing internet-based communications services, alleging infringement of U.S. Patent No. 8,295,802. The complaint seeks unspecified monetary damages, costs, attorneys’ fees and other appropriate relief. Based upon our preliminary investigation, we do not believe that our products infringe any valid or enforceable claim of the aforementioned patent and we plan to contest the claim vigorously. Notwithstanding their merits, accusations and lawsuits like these often require significant time and expense to defend, may negatively affect customer relationships, may divert management’s attention away from other

aspects of our operations and, upon resolution, may have a material adverse effect on our business, results of operations, financial condition and cash flows.

Certain technology necessary for us to provide our services may, in fact, be patented by other parties either now or in the future. If such technology were validly patented by another person, we would have to negotiate a license for the use of that technology. We may not be able to negotiate such a license at a price that is acceptable to us or at all. The existence of such a patent, or our inability to negotiate a license for any such technology on acceptable terms, could force us to cease using the technology and cease offering products and services incorporating the technology, which could materially and adversely affect our business and results of operations.

If we were found to be infringing on the intellectual property rights of any third party, we could be subject to liability for such infringement, which could be material. We could also be prohibited from using or selling certain products or services, prohibited from using certain processes, or required to redesign certain products or services, each of which could have a material adverse effect on our business and results of operations.

These and other outcomes may:

Our limited ability to protect our intellectual property rights could materially and adversely affect our business.

We rely, in part, on patent, trademark, copyright and trade secret law to protect our intellectual property in the U.S. and abroad. We cannot assure you that the particular forms of intellectual property protection we seek, including business decisions about when to file patents and when to maintain trade secrets, will be adequate to protect our business. We seek to protect our technology, software, documentation and other information under trade secret and copyright law, which afford only limited protection. For example, we typically enter into confidentiality agreements with our employees, consultants, third-party contractors, customers and vendors in an effort to control access to use and distribution of our technology, software, documentation and other information. These agreements may not effectively prevent unauthorized use or disclosure of confidential information and may not provide an adequate remedy in the event of such unauthorized use or disclosure, and it may be possible for a third party to legally reverse engineer, copy or otherwise obtain and use our technology without authorization. In addition, improper disclosure of trade secret information by our current or former employees, consultants, third-party contractors, customers or vendors to the public or others who could make use of the trade secret information would likely preclude that information from being protected as a trade secret.

We also rely, in part, on patent law to protect our intellectual property in the U.S. and internationally. Our intellectual property portfolio includes four issued U.S. patents, which we expect to expire between December

29

Table of Contents

2028 and February 2032. We also have eleven patent applications pending for examination in the U.S. and two patent applications pending for examination in foreign jurisdictions, all of which are related to U.S. applications. We cannot predict whether such pending patent applications will result in issued patents or whether any issued patents will effectively protect our intellectual property. Even if a pending patent application results in an issued patent, the patent may be circumvented or its validity may be challenged in various proceedings in U.S. District Court, before the U.S. Patent and Trademark Office or before their foreign equivalents, such as reexamination, which may require legal representation and involve substantial costs and diversion of management time and resources. In addition, we cannot assure you that every significant feature of our solutions is protected by our patents, or that we will mark our products with any or all patents they embody. As a result, we may be prevented from seeking damages in whole or in part for infringement of our patents.

The unlicensed use of our brand, including domain names, by third parties could harm our reputation, cause confusion among our customers and impair our ability to market our products and services. To that end, we have registered numerous trademarks and service marks, have applied for registration of additional trademarks and service marks and have acquired a number of domain names in and outside the U.S. to establish and protect our brand names as part of our intellectual property strategy. If our applications receive objections or are successfully opposed by third parties, it will be difficult for us to prevent third parties from using our brand without our permission. Moreover, successful opposition to our applications might encourage third parties to make additional oppositions or commence trademark infringement proceedings against us, which could be costly and time consuming to defend against. There have been in the past, and may be in the future, instances where third parties have used our trade names, or have adopted confusingly similar trade names to ours. We have been successful in asserting our rights in our trade names and causing such third parties to cease such use, but we may not be successful in the future. If we are not successful in protecting our trademarks, our trademark rights may be diluted and subject to challenge or invalidation, which could materially and adversely affect our brand.

Despite our efforts to implement our intellectual property strategy, we may not be able to protect or enforce our proprietary rights in the U.S. or internationally (where effective intellectual property protection may be unavailable or limited). For example, we have entered into agreements containing confidentiality and invention assignment provisions in connection with the outsourcing of certain software development, quality assurance and development activities to third-party contractors located in Canada, India, New Zealand, Russia and Ukraine. We have also entered into an agreement containing a confidentiality provision with a third-party contractor located in the Philippines, where we have outsourced a significant portion of our customer support function. We cannot assure you that agreements with these third-party contractors or their agreements with their employees and contractors will adequately protect our proprietary rights in the applicable jurisdictions and foreign countries, as their respective laws may not protect proprietary rights to the same extent as the laws of the U.S. In addition, our competitors may independently develop technologies similar or superior to our technology, duplicate our technology in a manner that does not infringe our intellectual property rights or design around any of our patents. Furthermore, detecting and policing unauthorized use of our intellectual property is difficult and resource-intensive. Moreover, litigation may be necessary in the future to enforce our intellectual property rights, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation, whether successful or not, could result in substantial costs and diversion of management time and resources and could have a material adverse effect on our business, financial condition and results of operations.

We license technology from third parties we do not control and cannot be assured of retaining such licenses.

We rely upon certain technology, including hardware and software, licensed from third parties. There can be no assurance that the technology licensed by us will continue to provide competitive features and functionality or that the licenses for technology currently utilized by us or other technology which we may seek to license in the future, will be available to us on commercially reasonable terms or at all. The loss of, or inability to maintain, existing licenses could result in shipment delays or reductions until equivalent technology or suitable alternative

30

Table of Contents

products are developed, identified, licensed and integrated, and could harm our business. These licenses are typically offered on standard commercial terms made generally available by the companies providing the licenses. The cost and terms of these licenses individually are not material to our business.

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

Nearly all of our customers authorize us to bill their credit card accounts directly for service fees that we charge. If people pay for our services with stolen credit cards, we could incur substantial third-party vendor costs for which we may not be reimbursed. Further, our customers provide us with credit card billing information online or over the phone, and we do not review the physical credit cards used in these transactions, which increases our risk of exposure to fraudulent activity. We also incur charges, which we refer to as chargebacks, from the credit card companies’ claims that the customer did not authorize the credit card transaction to purchase our service, something we have experienced in the past. If the number of unauthorized credit card transactions becomes excessive, we could be assessed substantial fines for excess chargebacks and we could lose the right to accept credit cards for payment. We have also been affected by the credit card breaches at various retail stores, which have caused millions of consumers to cancel credit cards as a result of the breach. We have found that some consumers do not renew their services after a card cancellation, which can have a material negative impact on our revenue. In addition, credit card issuers may change merchant standards, including data protection and documentation standards, required to utilize their services from time to time. If we fail to maintain compliance with current merchant standards, such as Payment Card Industry Data Security Standard, or PCI, or fail to meet new standards, the credit card associations could fine us or terminate their agreements with us, and we would be unable to accept credit cards as payment for our services. Our services may also be subject to fraudulent usage, including but not limited to revenue share fraud, domestic traffic pumping, subscription fraud, premium text message scams, and other fraudulent schemes. Although our customers are required to set passwords and Personal Identification Numbers, or PINs, to protect their accounts and may configure in which destinations international calling is enabled from their extensions, third parties may be able to access and use their accounts through fraudulent means. In addition, third parties may have attempted in the past, and may attempt in the future, to fraudulently induce domestic and international employees or consultants into disclosing customer credentials and other account information. Communications fraud can result in unauthorized access to customer accounts and customer data, unauthorized use of customers’ services, and charges to customers for fraudulent usage and expenses we must pay to carriers. We may be required to pay for these charges and expenses with no reimbursement from the customer, and our reputation may be harmed if our services are subject to fraudulent usage. Although we implement multiple fraud prevention and detection controls, we cannot assure you that these controls will be adequate to protect against fraud. Substantial losses due to fraud or our inability to accept credit card payments, which could cause our paid customer base to significantly decrease, could have a material adverse effect on our results of operations, financial condition and ability to grow our business.

Potential problems with our information systems could interfere with our business and operations.

We rely on our information systems and those of third parties for processing customer orders, distribution of our services, billing our customers, processing credit card transactions, customer relationship management, supporting financial planning and analysis, accounting functions and financial statement preparation and otherwise running our business. Information systems may experience interruptions, including interruptions of related services from third-party providers, which may be beyond our control. Such business interruptions could cause us to fail to meet customer requirements. All information systems, both internal and external, are potentially vulnerable to damage or interruption from a variety of sources, including without limitation, computer viruses, security breaches, energy blackouts, natural disasters, terrorism, war, telecommunication failures and employee or other theft, as well as third-party provider failures. Any disruption in our information systems and those of the third parties upon which we rely could have a significant impact on our business.

31

Table of Contents

We may implement enhanced information systems in the future to meet the demands resulting from our growth and to provide additional capabilities and functionality. The implementation of new systems and enhancements is frequently disruptive to the underlying business of an enterprise, and can be time-consuming and expensive, increase management responsibilities and divert management attention. Any disruptions relating to our systems enhancements or any problems with the implementation, particularly any disruptions impacting our operations or our ability to accurately report our financial performance on a timely basis during the implementation period, could materially and adversely affect our business. Even if we do not encounter these material and adverse effects, the implementation of these enhancements may be much more costly than we anticipated. If we are unable to successfully implement the information systems enhancements as planned, our financial position, results of operations and cash flows could be negatively impacted.

Our use of open source technology could impose limitations on our ability to commercialize our services.

We use open source software in our platform on which our services operate. There is a risk that the owners of the copyrights in such software may claim that such licenses impose unanticipated conditions or restrictions on our ability to market or provide our services. If such owners prevail in such claim, we could be required to make the source code for our proprietary software (which contains our valuable trade secrets) generally available to third parties, including competitors, at no cost, to seek licenses from third parties in order to continue offering our services, to re-engineer our technology, or to discontinue offering our services in the event re-engineering cannot be accomplished on a timely basis or at all, any of which could cause us to discontinue our services, harm our reputation, result in customer losses or claims, increase our costs or otherwise materially and adversely affect our business and results of operations. If a copyright holder of such open source software were to allege we had not complied with the conditions of one or more of these licenses, we could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, enjoined from the sale of our solutions that contained the open source software and required to comply with the foregoing conditions, which could disrupt the distribution and sale of some of our solutions.

We depend largely on the continued services of our senior management and other key employees, the loss of any of whom could adversely affect our business, results of operations and financial condition.

Our future performance depends on the continued services and contributions of our senior management and other key employees to execute on our business plan, and to identify and pursue opportunities and services innovations. The loss of services of senior management or other key employees could significantly delay or prevent the achievement of our development and strategic objectives. In particular, we depend to a considerable degree on the vision, skills, experience and effort of our Chief Executive Officer, Eric B. Stang. All of our executive officers and senior management may terminate employment with us at any time with no advance notice. The replacement of any of these senior management personnel would likely involve significant time and costs, and such loss could significantly delay or prevent the achievement of our business objectives. Many members of our senior management have been our employees for many years and therefore have significant experience and understanding of our business that would be difficult to replace. In addition, certain members of our senior management team, including our general counsel, who joined us in December of 2013, and our chief financial officer, who joined us in December of 2014, have worked together for only a relatively short period of time and it may be difficult to evaluate their effectiveness, on an individual or collective basis, and ability to address future challenges to our business. Our inability to attract and retain the necessary personnel could adversely affect our business, financial condition or results of business. We do not maintain key person insurance for any of our personnel.

If we are unable to hire, retain and motivate qualified personnel, our business will suffer.

Our future success depends, in part, on our continued ability to attract and retain highly skilled personnel. We believe there is, and will continue to be, intense competition for highly skilled technical and other personnel with experience in our industry in the San Francisco Bay Area, where our headquarters is located, and in other

32

Table of Contents

locations where we may maintain offices in the future. We must provide competitive compensation packages and a high-quality work environment to hire, retain and motivate employees. If we are unable to retain and motivate our existing employees or attract qualified personnel to fill key positions, we may be unable to manage our business effectively, including the development, marketing and sale of existing and new services, which could have a material adverse effect on our business, financial condition, and results of operations. To the extent we hire personnel from competitors, we may be subject to allegations such personnel have been improperly solicited or divulged proprietary or other confidential information.

We may expand through acquisitions of, or investments in, other companies, each of which may divert our management’s attention, result in additional dilution to our stockholders, increase expenses, disrupt our operations and harm our results of operations.

Our business strategy may, from time to time, include acquiring or investing in complementary services, technologies or businesses. We cannot assure you we will successfully identify suitable acquisition candidates, integrate or manage disparate technologies, lines of business, personnel and corporate cultures, realize our business strategy or the expected return on our investment, or manage a geographically dispersed company. Any such acquisition or investment could materially and adversely affect our results of operations. Acquisitions and other strategic investments involve significant risks and uncertainties, including:

Any acquisition or investment could expose us to unknown liabilities. Moreover, we cannot assure you that we will realize the anticipated benefits of any acquisition or investment. In addition, our inability to successfully operate and integrate newly acquired businesses appropriately, effectively, and in a timely manner could impair our ability to take advantage of future growth opportunities and other advances in technology, as well as on our revenue, gross margins and expenses.

Additionally, we have recently acquired companies which form the basis for our Business Promoter and Talkatone solutions. We are still going through the process of integrating the employee bases and technologies acquired from those companies, and cannot assure you we will be able to effectively integrate those assets with our resources; we may not be able to realize the potential growth and gain we anticipated at the time of acquisition.

We may expand our international operations, which may expose us to significant risks.

To date, we have not generated significant revenue from outside of the U.S. and Canada, but we expect to grow our international revenue in the future. The future success of our business will depend, in part, on our ability to expand our operations and customer base worldwide. Operating in international markets requires significant resources and management attention and will subject us to regulatory, economic and political risks different from those in the U.S. Because of our limited experience with international operations and developing and managing sales and distribution channels in international markets, our international expansion efforts may not be successful. In addition, we will face risks in doing business internationally that could materially and adversely affect our business, including:

Our failure to manage any of these risks successfully could harm our future international operations and our overall business.

We may not be able to manage our inventory levels effectively, which may lead to excess inventory or inventory obsolescence that would force us to incur inventory write-downs.

Our vendor-supplied on-premise appliances and end-point devices have lead times of up to 32 weeks for delivery and are built to satisfy our demand forecasts that are necessarily imprecise. It is likely that from time to time we will have either excess or insufficient product inventory. In addition, because we rely on third-party vendors for the supply of our devices, our inventory levels are subject to the conditions regarding the timing of purchase orders and delivery dates not within our control. Excess inventory levels would subject us to the risk of inventory obsolescence, while insufficient levels of inventory may negatively affect relations with customers. For instance, our customers rely upon our ability to meet committed delivery dates, and any disruption in the supply of our services could result in loss of customers or harm to our ability to attract new customers. Retailers may elect to return any unsold inventory without any penalty, which could result in a write down for excess inventory. Any of these factors could have a material adverse effect on our business, financial condition or results of operations.

Our corporate headquarters, both of our data centers and co-location facilities and our third-party customer service and support facility are located near known earthquake fault zones, and the occurrence of an earthquake, tsunami or other catastrophic disaster could damage our facilities or the facilities of our contractors, which could cause us to curtail our operations. Increased energy costs, power outages and limited availability of electrical resources may adversely affect our operating results.

Our corporate headquarters, both of our data centers and our customer service call center for Ooma office are located in northern California, our other customer service call center operated by our contractor is located in the Philippines, and our contract manufacturer facilities are located near the coast in China. All of these locations are on the Pacific Rim near known earthquake fault zones and, therefore, are vulnerable to damage from earthquakes and tsunamis. Additionally, our China facility and our sole third-party customer service and support facility in the Philippines are located in areas subject to typhoons. We and our contractors are also vulnerable to other types of disasters, such as power loss, fire, floods, pandemics, cyber-attack, war, political unrest and terrorist attacks and similar events that are beyond our control. If any disasters were to occur, our ability to operate our business could be seriously impaired, and we may endure system interruptions, reputational harm, loss of intellectual property, delays in our services development, lengthy interruptions in our services, breaches of data security and loss of critical data, all of which could harm our future results of operations. In addition, we do not carry earthquake insurance and we may not have adequate insurance to cover our losses resulting from other disasters or other similar significant business interruptions. Any significant losses not recoverable under our insurance policies could seriously impair our business and financial condition.

Changes in effective tax rates, or adverse outcomes resulting from examination of our income or other tax returns, could adversely affect our results of operations and financial condition.

Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

35

Table of Contents

Any changes in our effective tax rate could adversely affect our results of operations.

We may be unable to use some or all of our net operating loss carryforwards, which could materially and adversely affect our reported financial condition and results of operations.

As of January 31, 2015, we had federal and state net operating loss carryforwards, or NOLs, of $56.2 million and $56.1 million, respectively, available to offset future taxable income, due to prior period losses, each of which, if not utilized, will begin to expire in 2029, however, California research and development tax credits can be carried forward indefinitely. We also have federal research and development tax credit carryforwards that will begin to expire in 2029. Realization of these net operating loss and research tax credit carryforwards depends on future income, and there is a risk that our existing carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could materially and adversely affect our results of operations.

Under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, our ability to utilize net operating loss carryforwards or other tax attributes, such as research tax credits, in any taxable year may be limited if we experience an “ownership change.” A Section 382 “ownership change” generally occurs if one or more stockholders or groups of stockholders, who own at least 5% of our stock, increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws. We completed a Section 382 analysis through January 31, 2015 and determined that an ownership change, as defined under Section 382 of the Internal Revenue Code, occurred in prior years. Based on the analysis, we determined that we had undergone three ownership changes. The first and second ownership changes occurred in April 2005 and the third change occurred in February 2009. NOLs presented account for any limited and potential lost attributes due to the ownership changes and their respective expiration dates. The NOLs in the second table of Note 10 of the notes to our consolidated financial statements reflect the available NOLs we expect to use.

No deferred tax assets have been recognized on our balance sheet related to these NOLs, as they are fully reserved by a valuation allowance. If we have previously had, or have in the future, one or more Section 382 “ownership changes,” including in connection with our initial public offering or this offering, or if we do not generate sufficient taxable income, we may not be able to utilize a material portion of our NOLs, even if we achieve profitability. If we are limited in our ability to use our NOLs in future years in which we have taxable income, we will pay more taxes than if we were able to fully utilize our NOLs. This could materially and adversely affect our results of operations.

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

Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The estimates and forecasts in this prospectus relating to the size and expected growth of our market, including our estimated annual recurring revenue based on various assumptions, may prove to be inaccurate. Even if the market in which we compete meets the size estimates and growth forecasted in this prospectus, our business could fail to grow at similar rates, if at all.

Risks Related to Federal, State and International Regulation

Our services are subject to regulation and future legislative or regulatory actions could adversely affect our business and expose us to liability.

Federal Regulation

Our business is regulated by the Federal Communications Commission, or FCC. As a communications services provider, we are subject to FCC regulations relating to privacy, disability access, porting of numbers,

36

Table of Contents

Federal Universal Service Fund, or USF, contributions, E-911, and other matters. If we do not comply with FCC rules and regulations, we could be subject to FCC enforcement actions, fines, loss of licenses, and possibly restrictions on our ability to operate or offer certain of our services. Any enforcement action by the FCC, which may include a public process, would hurt our reputation in the industry, possibly impair our ability to sell our services to customers and could have a materially adverse impact on our revenue.

If the FCC classifies interconnected VoIP service as a telecommunications service subject to common carrier regulation, we could be subject to additional regulation under federal and state telecommunications laws. Compliance with such laws could increase our cost of doing business.

State Regulation

We are also subject to state consumer protection laws, as well as U.S. state, municipal and local sales, use, excise, utility user and ad valorem taxes, fees or surcharges. The imposition of such regulatory obligations or the imposition of additional taxes on our services could increase our cost of doing business and limit our growth.

International Regulation

As we expand internationally, we may be subject to telecommunications, consumer protection, data privacy and other laws and regulations in the foreign countries where we offer our services. For example, we are a provider of internet voice telecommunications services in Canada. As a provider of internet voice communications services, we are subject to regulation in Canada by the CRTC. We are also subject to Canadian federal privacy laws and provincial consumer protection legislation.

In addition, our international operations are potentially subject to country-specific governmental regulation and related actions that may increase our cost or impact our product and service offerings or prevent us from offering or providing our products and services in certain countries. Certain of our services may be used by customers located in countries where VoIP and other forms of IP communications may be illegal or require special licensing. In countries where local laws and regulations prohibit (or come to prohibit) the use of our products, users may continue to use our products and services, which could subject us to costly penalties or governmental action adverse to our business and damaging to our brand and reputation, our international expansion efforts, or our business and operating results.

The FCC continues to consider additional 911 requirements, including requiring us to deploy an E-911 service that automatically determines the location of our customers. The adoption of such requirements could increase our costs that could make our service more expensive, decrease our profit margins, or both.

The FCC is actively considering additional 911 requirements for interconnected VoIP providers, non-interconnected VoIP providers and texting providers. The outcome of the FCC’s proceedings cannot be determined at this time and we may or may not be able to comply with any such obligations that may be adopted. At present, we have no means to automatically identify the physical location of our customers on the internet. Changes to the FCC’s VoIP E-911 rules may adversely affect our ability to deliver our service to new and existing customers in all geographic regions or to nomadic customers who move to a location where emergency calling services compliant with the FCC’s mandates are unavailable. Our compliance with the FCC’s VoIP E-911 order and related costs puts us at a competitive disadvantage to VoIP service providers who are either not subject to the requirements or have chosen not to comply with the FCC’s mandates. We cannot guarantee emergency calling service consistent with the VoIP E-911 order will be available to all of our customers, especially those accessing our services on a mobile device or from outside of the U.S. The FCC’s current VoIP E-911 order or follow-on orders or clarifications, the impact on our customers due to service price increases or other factors could have a material adverse effect on our business, financial condition or operating results.

The FCC order reforming the system of payments between regulated carriers we partner with to interface with the public switched telephone network, or PSTN, could increase our costs of providing service, which could result in increased rates for service, making our offerings less competitive than others in the marketplace, or reduce our profitability.

In 2011, the FCC reformed the system under which regulated providers of telecommunications services compensate each other for various types of traffic, including VoIP traffic that terminates on the PSTN and applied new call signaling requirements to VoIP and other service providers. The FCC’s rules concerning charges for transmission of VoIP traffic could result in an increased cost to terminate the traffic, could reduce the availability of services or increase the price of services from our underlying providers, or could otherwise impact the wholesale telecommunications market in a way that adversely impacts our business. To the extent that we transmit traffic not subject to a specific intercarrier compensation arrangement and another provider were to assert that the traffic we exchange with them is subject to higher levels of compensation than what we, or the third parties terminating our traffic to the PSTN, pay today (if any), our termination costs could increase.

If we cannot comply with the FCC’s rules imposing call signaling requirements on VoIP providers like us, we may be subject to fines, cease and desist orders, or other penalties.

The FCC order reforming the system of compensation for various types of traffic also included rules to address calls for which identifying information is missing or masked in ways that impede billing for such traffic. The FCC’s rules require, among other things, interconnected VoIP providers like us, who originate interstate or intrastate traffic destined for the PSTN, to transmit the telephone number associated with the calling party to the next provider in the call path. Intermediate providers must pass unaltered calling party number or charge number signaling information they receive from other providers to subsequent providers in the call path. To the extent that we pass traffic that does not have appropriate calling party number or charge number information, we could be subject to fines, cease and desist orders, or other penalties.

We may not be able to comply with FCC rules governing completion of calls to rural areas and related reporting requirements.

On November 8, 2013, the FCC issued a Report and Order and Further Notice of Proposed Rulemaking adopting rules to address problems with rural call completion and proposing additional requirements. The new rules apply to interconnected VoIP providers like us. The Commission imposed recording, retention, and reporting requirements to increase its ability to monitor and redress rural call completion problems. These new rules also support the Commission’s efforts to enforce restrictions on blocking, choking, reducing, or restricting calls. Under the rules, a covered provider must record and retain, for at least six months, information about calls attempts to rural areas and must report that data to the FCC on a quarterly basis. If we cannot comply with these rules, we could be subject to investigation and enforcement action and could be exposed to substantial liability. In addition, complying with these rules may increase our cost of doing business and may also increase the cost of services we purchase from our underlying telecommunications providers. The FCC also has increased enforcement activity related to completion of calls to rural customers, and we could be subject to substantial fines and to conduct requirements that could increase our costs if we are the subject of an enforcement proceeding and cannot demonstrate calls from our customers to rural customers are completed at a satisfactory rate.

The FCC has continued to increase regulation of interconnected VoIP services and may at any time determine certain VoIP services are telecommunications services subject to traditional common carrier regulation.

The FCC is considering, in various proceedings, issues arising from the transition from traditional copper networks to IP networks. It has, among other things, launched a series of trials and experiments designed to gather data about this transition, and to support the FCC’s effort to ensure public safety, enable universal access, and protect consumers and competition. The FCC is also considering whether interconnected VoIP services

38

Table of Contents

should be treated as telecommunications services, which could subject interconnected VoIP services to additional common carrier regulation. The FCC’s efforts may result in additional regulation of IP network and service providers, which may negatively affect our business.

The FCC adopted rules concerning disabilities access requirements that may expand disabilities access requirements to additional services we offer.

In October 2010, the Twenty-First Century Communications and Video Accessibility Act, or the CVAA, was signed into law. The CVAA and the FCC’s implementing rules imposes disability access, recordkeeping, certification, and other compliance obligations on interconnected VoIP providers and on providers of other Advanced Communications services, including non-interconnected VoIP and electronic messaging services. In addition, the CVAA and the FCC’s implementing rules include complaint filing procedures to address accessibility complaints. These new obligations could increase our expenses, which would have an adverse effect on our operating results. Failure to comply with these obligations could expose us to FCC enforcement actions and liability.

Reform of federal and state Universal Service Fund programs could increase the cost of our service to our customers, diminishing or eliminating our pricing advantage.

The FCC and a number of states are considering reform or other modifications to Universal Service Fund programs. The way we calculate our contribution may change if the FCC or certain states engage in reform or adopt other modifications. In April 2012, the FCC released a Further Notice of Proposed Rulemaking to consider reforms to the manner in which companies, like us, contribute to the federal Universal Service Fund program, and in August 2014, the FCC ordered the Federal-State Joint Board on Universal Service to make a recommendation on how to reform the universal service contribution rules by April 7, 2015, although the recommendation has not been released as of the date hereof. In addition, the FCC is considering whether non-interconnected VoIP providers, texting providers, and broadband providers, among others, should contribute to the USF. We cannot predict the outcome of this proceeding nor its impact on our business at this time.

Should the FCC or certain states adopt new contribution mechanisms or otherwise modify contribution obligations that increase our contribution burden, we will either need to raise the amount we currently collect from our customers to cover this obligation or absorb the costs, which would reduce our profit margins. Furthermore, the FCC has ruled that states can require us to contribute to state Universal Service Fund programs. A number of states already require us to contribute, while others are actively considering extending their programs to include the services we provide. We currently pass through Universal Service Fund contributions to our customers which may result in our services becoming less competitive as compared to those provided by others.

Our products must comply with industry standards, FCC regulations, state, local, country-specific and international regulations, and changes may require us to modify existing products and/or services.

In addition to reliability and quality standards, the market acceptance of telephony over broadband IP networks is dependent upon the adoption of industry standards so that products from multiple manufacturers are able to communicate with each other. Our unique hybrid SaaS connectivity platform relies on communication standards such as SIP, SRTP and network standards such as TCP/IP and UDP to interoperate with other vendors’ equipment. There is currently a lack of agreement among industry leaders about which standard should be used for a particular application and about the definition of the standards themselves. These standards, as well as audio and video compression standards, continue to evolve. We also must comply with certain rules and regulations of the FCC regarding electromagnetic radiation and safety standards established by Underwriters Laboratories, as well as similar regulations and standards applicable in other countries. Standards are frequently modified or replaced. As standards evolve, we may be required to modify our existing products or develop and support new versions of our products. We must comply with certain federal, state and local requirements regarding how we

39

Table of Contents

interact with our customers, including marketing practices, consumer protection, privacy, and billing issues, the provision of 9-1-1 emergency service and the quality of service we provide to our customers. The failure of our products and services to comply, or delays in compliance, with various existing and evolving standards could delay or interrupt volume production of our VoIP telephony products, subject us to fines or other imposed penalties, or harm the perception and adoption rates of our service, any of which would have a material adverse effect on our business, financial condition or operating results.

Failure to comply with communications and telemarketing laws could result in significant fines or place significant restrictions on our business.

We rely on a variety of marketing techniques, including telemarketing and email marketing campaigns. We also record certain telephone calls between our customers or potential customers and our sales and service representatives for training and quality assurance purposes. These activities are subject to a variety of state and federal laws such as the Telephone Consumer Protection Act of 1991 (also known as the Federal Do-Not-Call law, or the TCPA), the Telemarketing Sales Rule, the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 (also known as the CAN-SPAM Act) and various U.S. state laws regarding telemarketing and telephone call recording. These laws are subject to varying interpretations by courts and governmental authorities and often require subjective interpretation, making it difficult to predict their application and therefore making our compliance efforts more challenging. We cannot be certain our efforts to comply with these laws, rules and regulations will be successful, or, if they are successful, that the cost of such compliance will not be material to our business. Changes to these or similar laws, or to their application or interpretation, or new laws, rules and regulations governing our communication and marketing activities could adversely affect our business. In the event that any of these laws, rules or regulations significantly restricts our business, we may not be able to develop adequate alternative communication and marketing strategies. Further, non-compliance with these laws, rules and regulations carries significant financial penalties and the risk of class action litigation, which would adversely affect our financial performance and significantly harm our reputation and our business.

We process, store, and use personal information and other data, which subjects us and our customers to a variety of evolving governmental regulation, industry standards and self-regulatory schemes, contractual obligations, and other legal obligations related to privacy, which may increase our costs, decrease adoption and use of our products and services, and expose us to liability.

There are a number of U.S. federal, state and local, and foreign laws and regulations, as well as contractual obligations and industry standards, that provide for certain obligations and restrictions with respect to data privacy and security, and the collection, storage, retention, protection, use, processing, transmission, sharing, disclosure, and protection of personal information and other customer data. The scope of these obligations and restrictions is changing, subject to differing interpretations, and may be inconsistent among countries or conflict with other rules, and their status remains uncertain. Within the European Union, or EU, strict laws already apply in connection with the collection, storage, retention, protection, use, processing, transmission, sharing, disclosure, and protection of personal information and other customer data. The EU model has been replicated in many jurisdictions outside the U.S., including Asia-Pacific Economic Cooperation countries. Regulators have the power to impose significant fines on non-compliant organizations. As internet commerce, communication technologies and the Internet of Things continue to evolve, increasing online service providers’ and network users’ capacity to collect, store, retain, protect, use, process and transmit large volumes of personal information, increasingly restrictive regulation by federal, state or foreign agencies becomes more likely. For example, a variety of regulations that would increase restrictions on online service providers in the area of data privacy are currently being proposed, both in the U.S. and in other jurisdictions, and we believe that the adoption of increasingly restrictive regulation in the field of data privacy and security is likely. In Canada, new anti-spam legislation prescribing certain rules regarding the use of electronic messages for commercial purposes took effect on July 1, 2014. This new law also contains provisions that took effect in January 2015, which impose certain restrictions on a service provider’s ability to electronically automatically update or change software used in a customer’s service without the customer’s consent. Penalties for non-compliance with the new Canadian anti-

40

Table of Contents

spam legislation are considerable, including administrative monetary penalties of up to $10 million and a private right of action. Obligations and restrictions imposed by current and future applicable laws, regulations, contracts and industry standards may affect our ability to provide all the current features of our small business, home and mobile products and services and our customers’ ability to use our products and services, and could require us to modify the features and functionality of our products and services. Such obligations and restrictions may limit our ability to collect, store, process, use, transmit and share data, and to allow our customers to collect, store, retain, protect, use, process, transmit, share and disclose data with others through our products and services. Compliance with such obligations and restrictions could increase the cost of our operations. Failure to comply with obligations and restrictions related to data privacy and security could subject us to lawsuits, fines, criminal penalties, statutory damages, consent decrees, injunctions, adverse publicity and other losses that could harm our business.

Our customers can use our services to store contact and other personal or identifying information, and to process, transmit, receive, store and retrieve a variety of communications and messages, including, for our Ooma Office customers, information about their own customers and other contacts. In addition, customers may use our services to transmit and store protected health information, or PHI, that is protected under the Health Insurance Portability and Accountability Act, or HIPAA. Noncompliance with laws and regulations relating to privacy such as HIPAA, as amended, and the HIPAA regulations, may lead to significant fines, penalties or liabilities. Our actual compliance, our customers’ perception of our compliance, costs of compliance with such regulations and customer concerns regarding their own compliance obligations (whether factual or in error) may limit the use and adoption of our service and reduce overall demand. Furthermore, privacy concerns, including the inability or impracticality of providing advance notice to customers of privacy issues related to the use of our services, may cause our customers’ customers to resist providing the personal data necessary to allow our customers to use our services effectively. Even the perception of privacy concerns, whether or not valid, may inhibit market adoption of our service in certain industries.

In addition to government activity, privacy advocacy groups and industry groups have adopted and are considering the adoption of various self-regulatory standards and codes of conduct that may place additional burdens on us and our customers, which may further reduce demand for our services and harm our business.

While we try to comply with all applicable data protection laws, regulations, standards, and codes of conduct, as well as our own posted privacy policies and contractual commitments to the extent possible, any failure by us to protect our users’ privacy and data, including as a result of our systems being compromised by hacking or other malicious or surreptitious activity, could result in a loss of user confidence in our services and ultimately in a loss of users, which could materially and adversely affect our business. Our customers may also accidentally disclose their passwords, store them on a mobile device that is lost or stolen, or otherwise fall prey to attacks outside our system, creating the perception that our systems are not secure against third-party access. Additionally, our third-party contractors in the Philippines, India, Canada, New Zealand, Russia, and China may have access to customer data. If these or other third-party vendors violate applicable laws or our policies, such violations may also put our customers’ information at risk and could in turn have a material and adverse effect on our business.

Use or delivery of our services may become subject to new or increased regulatory requirements, taxes or fees.

The increasing growth and popularity of internet voice communications heighten the risk that governments will regulate or impose new or increased fees or taxes on internet voice communications services. To the extent the use of our services continues to grow, regulators may be more likely to seek to regulate or impose new or additional taxes, surcharges or fees on our services. Similarly, advances in technology, such as improvements in locating the geographic origin of internet voice communications, could cause our services to become subject to additional regulations, fees or taxes, or could require us to invest in or develop new technologies, which may be costly. In addition, as we continue to expand our user base and offer more services, we may become subject to new regulations, taxes, surcharges or fees. Increased regulatory requirements, taxes, surcharges or fees on internet voice communications services, which could be assessed by governments retroactively or prospectively,

41

Table of Contents

would substantially increase our costs, and, as a result, our business would suffer. In addition, the tax status of our services could subject us to conflicting taxation requirements and complexity with regard to the collection and remittance of applicable taxes. Any such additional taxes could harm our results of operations.

We are subject to anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and possibly other anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees and third-party intermediaries from authorizing, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We use third-party representatives for product testing, customs, export, and import matters outside of the U.S. In addition, as we increase our international sales and business, we may engage with business partners and third party intermediaries to sell our products and services abroad and to obtain necessary permits, licenses, and other regulatory approvals. We or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities.

Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources, significant defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, results of operations, and financial condition.

We are subject to governmental export and import controls, economic embargoes and trade sanctions that could impair our ability to expand our business to, and compete in, international markets and could subject us to liability if we are not in compliance with applicable laws.

Our products and services are subject to export and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. Exports of our products and services must be made in compliance with these laws and regulations. Obtaining the necessary authorizations, including any required license, for a particular sale may be time-consuming, is not guaranteed and may result in the delay or loss of sales opportunities. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges, fines which may be imposed on us and responsible employees or managers, and, in extreme cases, the incarceration of responsible employees or managers.

Moreover, U.S. export control laws and economic sanctions programs generally prohibit the export of certain products and services to countries, governments and persons subject to U.S. economic embargoes and trade sanctions unless a license, approval, or other authorization is obtained from the U.S. Government. Obtaining such licenses and authorizations may be time-consuming and is not guaranteed. Any violations of such economic embargoes and trade sanctions regulations could have negative consequences, including government investigations, penalties and reputational harm.

42

Table of Contents

In addition, any changes in our products or services, or changes in applicable export, import, embargo and trade sanctions regulations, may create delays in the introduction and sale of our products and services in international markets or, in some cases, prevent the export or import of our products and services to certain countries, governments, or persons altogether. Any change in export, import, embargo, or trade sanctions regulations, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons or technologies targeted by such regulations, could also result in decreased use of our products and services, or in our decreased ability to export or sell our products and services to existing or potential customers with international operations. Any decreased use of our products and services or limitation on our ability to export or sell our products and services would likely adversely affect our business.

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

We collect and remit state or municipal sales, use, excise, utility user and ad valorem taxes, fees, or surcharges on the charges to our customers for our services or goods in only those jurisdictions where we believe we have a legal obligation to do so or for business reasons to reduce risk. In addition, we have historically substantially complied with the collection of certain California sales/use taxes and financial contributions to the California 9-1-1 system (the Emergency Telephone Users Surcharge) and federal USF. With limited exception, we believe we are generally not subject to taxes, fees, or surcharges imposed by other state and municipal jurisdictions or that such taxes, fees, or surcharges do not apply to our service. There is uncertainty as to what constitutes sufficient “in state presence” for a state to levy taxes, fees and surcharges for sales made over the internet. Therefore, taxing authorities may challenge our position and may decide to audit our business and operations with respect to sales, use, telecommunications and other taxes, which could result in increased tax liabilities for us or our customers, which could materially and adversely affect our results of operations and our relationships with our customers.

Finally, the application of other indirect taxes (such as sales and use tax, value added tax, or VAT, goods and services tax, business tax, and gross receipt tax) to e-commerce businesses, such as ours, is a complex and evolving area. In November 2007, the U.S. federal government enacted legislation extending the moratorium on states and other local authorities imposing access or discriminatory taxes on the internet through November 2014. This moratorium does not prohibit federal, state, or local authorities from collecting taxes on our income or from collecting taxes due under existing tax rules. The application of existing, new, or future laws, whether in the U.S. or internationally, could have adverse effects on our business, prospects, and results of operations. There have been, and will continue to be, substantial ongoing costs associated with complying with the various indirect tax requirements in the numerous markets in which we conduct or will conduct business.

Risks Related to Being a Public Company

We have identified a material weakness in our internal control over financial reporting as of January 31, 2013, 2014 and 2015. If we fail to develop and maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in our company.

We will be required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting as of January 31, 2017. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting.

In connection with our financial statement close process for fiscal 2013, fiscal 2014 and fiscal 2015, we identified a material weakness in the design and operating effectiveness of our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, that creates a reasonable possibility a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

43

Table of Contents

The material weakness we identified resulted from a lack of sufficient number of qualified personnel within our accounting function who possessed an appropriate level of expertise to effectively perform the following functions:

We are taking numerous steps we believe will address the underlying causes of the material weakness described above, primarily through the hiring of additional accounting and finance personnel with technical accounting and financial reporting experience, development and implementation of policies, and improved processes and documented procedures. If we fail to effectively remediate deficiencies in our control environment or are unable to implement and maintain effective internal control over financial reporting to meet the demands that will be placed upon us as a public company, including the requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, we may be unable to accurately report our financial results, or report them within the timeframes required by law or exchange regulations.

Even if we are able to report our financial statements accurately and in a timely manner, if we do not make all necessary improvements to address the material weakness, continued disclosure of a material weakness will be required in future filings with the SEC, which could cause our reputation to be harmed and our stock price to decline.

We have not performed an evaluation of our internal control over financial reporting, such as required by Section 404 of the Sarbanes-Oxley Act, nor have we engaged our independent registered public accounting firm to perform an audit of our internal control over financial reporting as of any balance sheet date or for any period reported in our financial statements. Had we performed such an evaluation or had our independent registered public accounting firm performed an audit of our internal control over financial reporting, control deficiencies, including material weaknesses and significant deficiencies, in addition to those discussed above, may have been identified. In addition, we are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act, and as such we will elect to avail ourselves of the exemption from the requirement that our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act until we cease to be an “emerging growth company.”

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive management and qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, the listing requirements of the stock exchange on which our common stock is traded and other applicable securities rules and regulations. Compliance with these rules and regulations may increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly, and increase demand on our systems and resources, particularly after we are no longer an “emerging growth company.” The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect to our business and results of operations. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could harm our business and results of operations. Although we have already hired additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which will increase our costs and expenses.

The expenses incurred by public companies for reporting and corporate governance purposes have increased dramatically over the past several years. We expect these rules and regulations to increase our legal and financial compliance costs substantially and to make some activities more time consuming and costly. We are unable currently to estimate these costs with any degree of certainty. As a public company we also expect it will be more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

However, for as long as we remain an “emerging growth company” as defined in the JOBS Act, we will take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not “emerging growth companies,” including, but not limited to, exemption from the requirement to comply with the auditor attestation requirements of 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 will take advantage of these reporting exemptions until we are no longer an “emerging growth company.”

We will cease to be an “emerging growth company” upon the earliest of (i) January 31, 2021, (ii) the last day of the first fiscal year in which our annual gross revenue exceeds $1.0 billion, (iii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities or (iv) as of the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million as of the end of the second quarter of that fiscal year.

As a result of filings required of a public company, our business and financial condition has become more visible, which we believe may result in more litigation, including by competitors and other third parties. If such claims are successful, our business and results of operations could be materially and adversely affected, even if the claims do not result in litigation or are resolved in our favor. These claims, and the time and resources necessary to resolve them, could divert the resources of our management and materially and adversely affect our business and results of operations.

Our actual operating results may differ significantly from our guidance.

From time to time, we plan to release guidance in our quarterly earnings conference calls, quarterly earnings releases, or otherwise, regarding our future performance that represents our management’s estimates as of the date of release. This guidance, which will include forward-looking statements, will be based on projections prepared by our management. These projections will not be prepared with a view toward compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our registered public accountants nor any other independent expert or outside party compiles or examines the projections. Accordingly, no such person will express any opinion or any other form of assurance with respect to the projections.

Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. We intend to state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are not intended to imply that actual results could not fall outside of the suggested ranges. The principal reason that we release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such third parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results.

Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this “Risk Factors” section in this prospectus could result in the actual operating results being different from our guidance, and the differences may be adverse and material.

Risks Related to Owning Our Common Stock and This Offering

Sales of a substantial number of shares of our common stock in the public market, or the perception these sales might occur, could cause our share price to decline.

Sales of a substantial number of shares of our common stock in the public market after this offering, or the perception these sales might occur, could cause the market price of our common stock to decline and could impair our ability to raise capital through the sale of additional equity securities. After this offering, we will have              outstanding shares of our common stock, based on the number of shares outstanding as of             .

All of the shares of our common stock sold in this offering will be freely tradable without restriction or further registration under the Securities Act of 1933, as amended, or the Securities Act, except for any shares held by our “affiliates” as defined in Rule 144 under the Securities Act. The remaining              shares are currently restricted as a result of market stand-off agreements restricting their sale for 180 days after the date of this prospectus. In addition, substantially all of these shares are also subject to lock-up agreements with the underwriters. Credit Suisse Securities (USA) LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated may, in their sole discretion, permit our officers, directors, employees, and current security holders who are subject to lock-up agreements to sell shares prior to the expiration of the lock-up agreements.

Additionally, the shares of common stock subject to outstanding options under our equity incentive plans and the shares reserved for future issuance under our equity incentive plans will become eligible for sale in the public market in the future, subject to certain legal and contractual limitations.

After this offering, the holders of an aggregate of              shares of our common stock as of             , will have rights, subject to certain conditions, to require us to file registration statements covering their shares or to include their shares in registration statements we may file for ourselves or our stockholders. We also will register shares of common stock we may issue under our employee equity incentive plans. Once we register these shares, they will be able to be sold freely in the public market upon issuance, subject to existing market stand-off or lock-up agreements.

We cannot predict what effect, if any, market sales of securities held by our stockholders or the availability of these securities for future sale will have on the market price of our common stock. See “Underwriting” and “Shares Eligible for Future Sale” for a more detailed description of the restrictions on selling our securities after this offering.

We may also issue shares of our common stock or other securities from time to time as consideration for future acquisitions and investments. If any such acquisition or investment is significant, the number of shares of our common stock or the number or aggregate principal amount, as the case may be, of other securities we may issue may in turn be substantial. We may also grant registration rights covering those shares of our common stock or other securities in connection with any such acquisitions and investments.

Worldview Technology Partners and its affiliates own a significant portion of our stock and may limit your ability to influence corporate matters.

As of April 30, 2015, Worldview Technology Partners beneficially owned approximately 56.5% of our outstanding voting securities (assuming no conversion of preferred stock into common stock) and will beneficially own approximately         % upon the completion of this offering. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders. Also, Worldview Technology Partners will be able to control our management and affairs and matters requiring stockholder approval, including the election of directors and the approval of significant corporate transactions, such as mergers, consolidations or the sale of substantially all of our assets. Consequently, this concentration of ownership may have the effect of delaying or preventing a change of control, including a merger, consolidation or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if that change of control would benefit our other stockholders.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock could decline.

We expect that the trading price for our common stock will be affected by any research or reports that industry or financial analysts publish about us or our business. If one or more of the analysts who may elect to cover us downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease coverage of our company, our stock may lose visibility in the market, which in turn could cause its price to decline.

Our common stock could trade at prices below the initial public offering price.

There has not been a public trading market for shares of our common stock prior to this offering. An active trading market may not develop or be sustained after this offering. The initial public offering price for the shares of common stock sold in this offering will be determined by negotiations among us and representatives of the underwriters. This price may not be indicative of the price at which our common stock will trade after this offering, and our common stock could easily trade below the initial public offering price.

Our management has broad discretion in the use of the net proceeds from this offering and may not use the net proceeds effectively.

Our management will have broad discretion in the application of the net proceeds of this offering. We cannot specify with certainty the uses to which we will apply these net proceeds. The failure by our management to apply these funds effectively could adversely affect our ability to continue maintaining and expanding our business.

We have never paid cash dividends and do not anticipate paying any cash dividends on our common stock.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future. If we do not pay cash dividends, you would receive a return on your investment in our common stock only if the market price of our common stock increases before you sell your shares. Furthermore, we are party to credit agreements with Silicon Valley Bank which contain negative covenants that limit our ability to pay dividends. See the section entitled “Liquidity and Capital Resources.”

Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws will contain provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:

47

Table of Contents

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, the provisions of Section 203 of the Delaware General Corporate Law govern us. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time without the consent of our board of directors.

These and other provisions in our amended and restated certificate of incorporation and our bylaws and under Delaware law could discourage potential takeover attempts, reduce the price investors might be willing to pay in the future for shares of our common stock and result in the market price of our common stock being lower than it would be without these provisions. See the section entitled “Description of Capital Stock—Anti-Takeover Effects of Provisions of the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws.”

Our amended and restated certificate of incorporation to be in effect upon completion of this offering will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our amended and restated certificate of incorporation to be in effect upon completion of this offering provides that the Court of Chancery of the State of Delaware is the sole and exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, any action asserting a claim against us arising pursuant to any provisions of the General Corporation Law of the State of Delaware, our amended and restated certificate of incorporation or our amended and restated bylaws to be in effect upon completion of this offering, or any action asserting a claim against us that is governed by the internal affairs doctrine. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

The market price of our common stock is likely to be volatile and could decline following this offering, resulting in a substantial loss of your investment.

The market price of our common stock could be subject to wide fluctuations in response to, among other things, the factors described in this “Risk Factors” section or otherwise, and other factors beyond our control, such as fluctuations in the valuations of companies perceived by investors to be comparable to us.

Furthermore, the stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market fluctuations,

48

Table of Contents

as well as general economic, systemic, political and market conditions, such as recessions, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

Factors that could cause the market price of our common stock to fluctuate significantly include:

In the past, many companies that have experienced volatility in the market price of their stock have become subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could harm our business.

Because the public offering price of our common stock will be substantially higher than the net tangible book value per share of our outstanding common stock following this offering, new investors will experience immediate and substantial dilution.

The public offering price of our common stock is substantially higher than the net tangible book value per share of our common stock immediately following this offering based on the total value of our tangible assets less our total liabilities. Therefore, if you purchase shares of our common stock in this offering, you will experience immediate dilution of approximately $        per share, the difference between the public offering price of $        per share and the net tangible book value per share of our common stock as of April 30, 2015, after giving effect to the issuance of shares of our common stock in this offering. See the section entitled “Dilution.”
