Item 1A. Risk Factors

Risks Related to Our Business

We have a history of losses, we may not become profitable and our revenue growth may not continue.

We have incurred net losses in each fiscal year since our inception, including net losses attributable to our stockholders of $12.0 million in 2010, $10.3 million in 2011 and $7.4 million in 2012. As a result, we had an accumulated deficit of $73.5 million at December 31, 2012. We may not become profitable in the future if we fail to increase revenue and manage our expenses, or if we incur unanticipated liabilities. Revenue growth may slow or revenue may decline for a number of possible reasons, including slowing demand for our products or services, increasing competition, a decrease in the growth of, or decline in, our overall market, or our failure to capitalize on growth opportunities or introduce new products and services. In addition, we have incurred, and anticipate that we will continue to incur, significant legal, accounting and other expenses relating to being a public company. If our revenues do not increase at a rate to proportionally offset these expected increases in operating expenses, our operating margins will suffer. Further, in future periods, our revenues could decline and, accordingly, we may not be able to achieve profitability and our losses may increase. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a consistent basis. Any failure by us to achieve, maintain or increase profitability and continue our revenue growth could cause the price of our common stock to materially decline.

Our quarterly operating results are likely to vary significantly and to be unpredictable, which could cause the trading price of our stock to decline.

Our revenues and operating results could vary significantly from period to period as a result of a variety of factors, many of which are outside of our control. As a result, comparing our revenues and operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. We may not be able to accurately predict our future revenues or results of operations. We base our current and future expense levels on our operating plans and sales forecasts, and our operating costs are relatively fixed in the short-term. As a result, we may not be able to reduce our costs sufficiently to compensate for an unexpected shortfall in revenues, and even a small shortfall in revenues could disproportionately and adversely affect financial results for that quarter. In addition, we recognize revenues from sales to some customers or resellers when cash is received, which may be delayed because of changes or issues with those customers or resellers. If our revenues or operating results fall below the expectations of investors or any securities analysts that cover our stock, the price of our common stock could decline substantially.

In addition to other risk factors listed in this section, factors that may individually or cumulatively affect our operating results from period to period include:

Reliance on a concentration of shipments at the end of the quarter could cause our revenue to fall below expected levels, resulting in a decline in our stock price.

Historically, we have received a significant majority of a quarter’s sales orders and generated a significant majority of a quarter’s revenue during the last two weeks of the quarter. The fact that so many orders arrive at the end of a quarter means that our revenue may move from one quarter to the next if we cannot fulfill all of the orders and satisfy all of the revenue recognition criteria under our accounting policies before the quarter ends.

This pattern is a result of customer buying habits and the efforts of our sales force and channel partners to meet or exceed quarterly quotas. If expected revenue at the end of any quarter is delayed because anticipated purchase orders fail to materialize, our logistics partners’ fail to ship products on time, we fail to manage our inventory properly, we fail to release new products on schedule, or for any other reason, then our revenue for that quarter could fall below our expectations or those of securities analysts and investors, resulting in a decline in our stock price.

We rely on third party channel partners to generate a majority, and to fulfill substantially all, of our revenue, and if we fail to expand and manage our distribution channels, our revenues could decline and our growth prospects could suffer.

Historically our channel partners have originated more than 35%, and fulfilled almost 85%, of our sales, and we expect that channel sales will represent a substantial portion of our revenues for the foreseeable future. Our ability to expand our distribution channels depends in part on our ability to educate our channel partners about our products and services, which are complex. Our agreements with our channel partners are generally non-exclusive and many of our channel partners have more established relationships with our competitors. If our channel partners choose to place greater emphasis on products and services of their own or those offered by our competitors, our ability to grow our business and sell our products may be adversely affected. If our channel partners do not effectively market and sell our products and services, or if they fail to meet the needs of our customers, then our ability to grow our business and sell our products may be adversely affected. The loss of one or more of our larger channel partners, who may cease marketing our products with limited or no notice, and our possible inability to replace them could adversely affect our sales. Our failure to recruit additional channel partners, or any reduction or delay in their sales of our products and services or conflicts between channel sales and our direct sales and marketing activities could materially and adversely affect our results of operations.

We face intense competition, especially from larger, better-known companies and we may lack sufficient financial or other resources to maintain or improve our competitive position.

The market for business security products is intensely competitive and we expect competition to intensify in the future. Our competitors include companies such as Akamai Technologies, Inc., Citrix Systems, Inc., F5 Networks, Inc., International Business Machines Corporation (“IBM”), McAfee, Inc. (a subsidiary of Intel Corporation), Oracle Corporation, Symantec Corporation and other point solution security vendors.

Many of our existing and potential competitors may have substantial competitive advantages such as:

As a result, they may be able to adapt more quickly and effectively to new or emerging technologies and changing opportunities, standards or customer requirements. In addition, these companies could reduce, the price of their competing products, resulting in intensified pricing pressures within our market. Further, some of our larger competitors have substantially broader product offerings and leverage their relationships based on other products or incorporate functionality into existing products in a manner that discourages customers from purchasing our products. Customers may elect to accept a bundled product offering from our competitors, even if it has more limited functionality than our product offering, instead of adding the additional appliances required to implement our offering. The consolidation in our industries, such as IBM’s acquisition of Guardium, Inc., Oracle’s acquisition of Secerno, Ltd. and McAfee’s acquisition of Sentrigo, Inc., increases the likelihood of competition based on integration or bundling, particularly where their products and offerings are effectively integrated, and we believe that consolidation in our industry may increase the competitive pressures we face on all our products. If we are unable to sufficiently differentiate our products from the integrated or bundled products of our competitors, such as by offering enhanced functionality, performance or value, we may see a decrease in demand for those products, which would adversely affect our business, operating results and financial condition. Further, it is possible that continued industry consolidation may impact customers’ perceptions of the viability of smaller or even medium-sized software firms and consequently customers’ willingness to purchase from such firms. Similarly, if customers seek to concentrate their software purchases in the product portfolios of a few large providers, we may be at a competitive disadvantage notwithstanding the superior performance that we believe our products can deliver. Larger competitors are also often in a better position to withstand any significant reduction in capital spending by customers, and will therefore not be as susceptible to economic downturns.

Also, many of our smaller competitors that specialize in providing protection from a single type of business security threat may deliver these specialized business security products to the market more quickly than we can or may introduce innovative new products or enhancements before we do. Conditions in our markets could change rapidly and significantly as a result of technological advancements or continuing market consolidation.

We may not compete successfully against our current or potential competitors. Companies competing with us may introduce products that have greater performance or functionality, are easier to implement or use, or incorporate technological advances that we have not yet developed or implemented. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources. In addition, companies competing with us may price their products more competitively than ours, or have an entirely different pricing or distribution model. Increased competition could result in fewer customer orders, price reductions, reduced operating margins and loss of market share. Further, we may be required to make substantial additional investments in research, development, marketing and sales in order to respond to competition, and we cannot assure you that we will be able to compete successfully in the future.

We operate in an evolving market that has not yet reached widespread adoption and where new or existing technologies that may be perceived to address the risks in different ways could gain wide adoption and supplant some or all of our products and services, making analysis of trends or predictions about our business difficult and potentially weakening our sales and our financial result.

We are in a new, rapidly evolving category in the security industry that focuses on securing our customers’ high-value business data. We offer database, file and web application security in an integrated, modular business security solution. Because we depend in part on the market’s acceptance of our products and customers may choose to acquire technologies that are not directly comparable to ours, it is difficult to evaluate trends that may affect our business, including how large the business security market will be and what products customers will adopt. For example, organizations that use other security products, such as network firewalls, security information and event management (“SIEM”) products or data loss prevention (“DLP”) solutions, may believe that these security solutions sufficiently protect access to sensitive data. Therefore, they may continue spending their IT security budgets on these products and may not adopt our business security solutions in addition to such products. If customers do not recognize the benefit our business security solution offers in addition to existing security products, then our revenue may not grow quickly or may decline, and our stock price could decline.

The introduction of products and services embodying new technologies could render some or all of our existing products and services obsolete or less attractive to customers. Other business security technologies exist or could be developed in the future, and our business could be materially negatively affected if such technologies are widely adopted. We may not be able to successfully anticipate or adapt to changing technology or customer requirements on a timely basis, or at all. Currently less than 30% of our customers have purchased more than one of our product families. Even if customers purchase our products, they may not make repeat purchases or purchase other elements of our SecureSphere Business Security Suite, which may be exacerbated by the rapid evolution of our market. If we are unable to entice customers to buy products from multiple product families, then our revenue may not grow quickly or may decline, and our stock price could decline. If we fail to keep up with technological changes or to convince our customers and potential customers of the value of our solutions even in light of new technologies, our business, financial condition and results of operations could be materially and adversely affected.

In addition, because of our rapidly evolving market, any predictions about our future revenue may not be as accurate as they would be if we operated in a more established market.

If we do not successfully anticipate market needs and opportunities or changes in the legal, regulatory and industry standard landscape and make timely enhancements to our products and develop new products that meet those needs developments, we may not be able to compete effectively and our ability to generate revenues will suffer.

The business security market is characterized by rapid technological advances, changes in customer requirements, including customer requirements driven by changes to legal, regulatory and self-regulatory compliance mandates, frequent new product introductions and enhancements and evolving industry standards in computer hardware and software technology. Customers and industry analysts expect speedy introduction of software to respond to new threats, requirements and risks and to add new functionality, and we may be unable to meet these expectations. As a result, we must continually change and improve our products in response to changes in operating systems, application software, computer and communications hardware, networking software, data center architectures, programming tools and computer language technology. Moreover, the technology in our products is especially complex because it needs to effectively identify and respond to methods of attack and theft, while minimizing the impact on database, file system and web application performance. In addition, our products must successfully interoperate with products from other vendors.

We cannot guarantee that we will be able to anticipate future market needs and opportunities or be able to develop product enhancements or new products to meet such needs or opportunities in a timely manner or at all. Since developing new products or new versions of, or add-ons to, existing products is complex, the timetable for their commercial release is difficult to predict and may vary from our historical experience, which could result in delays in their introduction from anticipated or announced release dates. We may not offer updates as rapidly as new threats affect our customers or our newly developed products or enhancements may have defects, errors or failures. If we do not quickly respond to the rapidly changing and rigorous needs of our customers by developing and introducing on a timely basis new and effective products, upgrades and services that can respond adequately to new security threats, our competitive position, business and growth prospects will be harmed.

Even if we are able to anticipate, develop and commercially introduce enhancements and new products, there can be no assurance that we will be successful in developing sufficient market awareness of them or that such enhancements or new products will achieve widespread market acceptance. For example, while the majority of our current revenues are derived from the sales of our SecureSphere appliances, we are now offering cloud-based business security services through Incapsula. The market for cloud-based business security solutions is relatively new and it is uncertain whether Incapsula’s services will gain market acceptance. In addition, diversifying our product offerings will require significant investment and planning, will bring us more directly into competition with software providers that may be better established or have greater resources than we do, will require additional investment of time and resources in the development and training of our channel and strategic partners and will entail significant risk of failure.

Further, one factor that drives demand for our products and services is the legal, regulatory and industry standard framework in which our customers operate, and we expect that will continue for the foreseeable future. For example, many of our customers purchase our web application security products to help them comply with the security standards developed and maintained by the Payment Card Industry (“PCI”) Security Standards Council (the “PCI Council”), which apply to companies that process or store credit card information. Laws, regulations and industry standards are subject to drastic changes that, particularly in the case of industry standards, may arrive with little or no notice, and these could either help or hurt the demand for our products. If we are unable to adapt our products and services to changing regulatory standards in a timely manner, or if our products fail to expedite our customers’ compliance initiatives, our customers may lose confidence in our products and could switch to products offered by our competitors. In addition, if regulations and standards related to business security are changed in a manner that makes them less onerous, our customers may view government and industry regulatory compliance as less critical to their businesses, and our customers may be less willing to purchase our products and services. In either case, our sales and financial results would suffer.

If we fail to anticipate market requirements or fail to develop and introduce product enhancements or new products to meet those needs in a timely manner, it could cause us to lose customers and such failure could substantially decrease or delay market acceptance and sales of our present and future products, which would significantly harm our business, financial condition and results of operations.

Real or perceived errors, failures or bugs in our products, particularly those that result in our customers experiencing security breaches, could adversely affect our reputation and business could be harmed.

Our products and services are very complex and have contained and may contain undetected defects or errors, especially when first introduced or when new versions are released. Defects in our products may impede or block network traffic or cause our products or services to fail to help secure high-value business data. Defects in our products may lead to product returns and require us to implement design changes or software updates.

Any defects or errors in our products, or the perception of such defects or errors, could result in:

Data thieves are sophisticated, often affiliated with organized crime and operate large scale and complex automated attacks. In addition, their techniques change frequently and generally are not recognized until launched against a target. If we fail to identify and respond to new and complex methods of attack and to update our products to detect or prevent such threats in time to protect our customers’ high-value business data, our business and reputation will suffer.

In addition, many of our end-user customers use our products in applications that are critical to their businesses and may have a greater sensitivity to defects in our products than to defects in other, less critical, software products. An actual or perceived security breach or theft of the sensitive data of one of our customers, regardless of whether the breach is attributable to the failure of our products or services, could adversely affect the market’s perception of our security products. Despite our best efforts, there is no guarantee that our products will be free of flaws or vulnerabilities, and even if we discover these weaknesses we may not be able to correct them promptly, if at all. Our customers may also misuse our products, which could result in a breach or theft of business data.

Although we have limitation of liability provisions in our standard terms and conditions of sale, they may not fully or effectively protect us from claims as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries. The sale and support of our products also entail the risk of product liability claims. We maintain insurance to protect against certain claims associated with the use of our products, but our insurance coverage may not adequately cover any claim asserted against us. In addition, even claims that ultimately are unsuccessful could result in our expenditure of funds in litigation and divert management’s time and other resources.

False detection of security breaches or false identification of malicious sources could adversely affect our business.

Our business security products may falsely detect threats that do not actually exist. For example, our ThreatRadar product relies on information on attack sources aggregated from third-party data providers who monitor global malicious activity originating from anonymous proxies, specific IP addresses, botnets and phishing sites. If the information from these data providers is inaccurate, the potential for false positives increases. These false positives, while typical in the industry, may impair the perceived reliability of our products and may therefore adversely impact market acceptance of our products. If our products and services restrict access to important databases, files or applications based on falsely identifying users or traffic as an attack or otherwise unauthorized, this could adversely affect customers’ businesses. Any such false identification of users or traffic could result in negative publicity, loss of customers and sales, increased costs to remedy any problem and costly litigation.

Delays or interruptions in the manufacturing and delivery of SecureSphere appliances by our sole source manufacturer may harm our business.

Our hardware appliances are built by a single manufacturer. Our reliance on a sole manufacturer, particularly a foreign manufacturer, involves several risks, including a potential inability to obtain an adequate supply of appliances and limited control over pricing, quality and timely delivery of products. In addition, replacing this manufacturer may be difficult and could result in an inability or delay in obtaining products. In addition, if or for other reasons, we may be unable to fulfill customer orders and our operating results may fluctuate from period to period, particularly if a disruption occurs near the end of a fiscal period.

Our manufacturer’s ability to timely manufacture and ship our appliances in large quantities depends on a variety of factors. The manufacturer relies on a limited number of sources for the supply of functional components, such as semiconductors, printed circuit boards and hard disk drives. Functional component supply shortages or delays could prevent or delay the manufacture and shipment of appliances and, in the event of shortages or delays, we may not be able to procure alternative functional components on similar pricing terms, if at all. In addition, contractual restrictions or claims for infringement of intellectual property rights may restrict our manufacturer’s use of certain components. These restrictions or claims may require our manufacturer to utilize alternative components or obtain additional licenses or technologies, and may impede its ability to manufacture and deliver appliances on a timely or cost-effective basis. If at some point, the manufacturer is no longer financially viable, we may lose our source of supply with little or no notice or recourse. Further, even if quality products are timely manufactured, delays in shipping may occur, resulting in delayed satisfaction of a primary revenue recognition criterion.

In the event of an interruption from this manufacturer, we may not be able to develop alternate or secondary sources in a timely manner. If we are unable to buy our appliances in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver products to our channel partners and customers, which would seriously affect present and future sales.

A failure to manage excess inventories or inventory shortages could result in decreased revenue and gross margins and harm our business.

We purchase products from our manufacturing partner outside of and in advance of reseller or customer orders, which we hold in inventory and resell. If we fail to accurately predict demand and as a result our manufacturers maintain insufficient hardware inventory or excess inventory, we may be unable to timely deliver ordered products or may have substantial inventory expense. Because our channel partners do not purchase our products in advance of customer orders, we may face additional difficulty in accurately forecasting demand for our hardware products. There is a risk we may forecast incorrectly and may be unable to sell excess products ordered from our manufacturing partner. Inventory levels in excess of customer demand may result in inventory write-downs, and the sale of excess inventory at discounted prices could significantly impair our brand image and have an adverse effect on our financial condition and results of operations.

Conversely, if we underestimate demand for our products or if our manufacturing partner fails to supply products we require at the time we need them, we may experience inventory shortages. Inventory shortages might delay shipments to resellers, distributors and customers or cause us to lose sales. Further, as the size of individual orders increases, the risk that we may be unable to cause delivery of unforecasted orders also increases, particularly near the end of quarterly periods. These shortages may diminish the loyalty of our channel partners or customers.

The difficulty in forecasting demand also makes it difficult to estimate our future financial condition and results of operations from period to period. A failure to accurately predict the level of demand for our products could adversely affect our net revenues and net income, and we are unlikely to forecast such effects with any certainty in advance.

We have operations outside of the United States and a significant portion of our customers and suppliers are located outside of the United States, which subjects us to a number of risks associated with conducting international operations.

We market and sell our products throughout the world and have personnel in many parts of the world. In addition, we have sales offices and research and development facilities outside the United States and we conduct, and expect to continue to conduct, a significant amount of our business with companies that are located outside the United States, particularly in Israel, Asia and Europe. We also source our components for our products from various geographical regions and ship components from a foreign production facility. Therefore, we are subject to risks associated with having international sales and worldwide operations, including:

Our product and service sales may be subject to foreign governmental regulations, which vary substantially from country to country and change from time to time. Failure to comply with these regulations could adversely affect our business. Violations of laws or key control policies by our employees, contractors, channel partners or agents could result in delays in revenue recognition, financial reporting misstatements, fines, penalties or the prohibition of the importation or exportation of our products and services and could have a material adverse effect on our business and results of operations.

A portion of our revenue is generated by sales to government entities, which are subject to a number of challenges and risks.

Sales to U.S. and foreign federal, state and local governmental agency customers have accounted for approximately 12% of our bookings in each of the years ended December 31, 2011 and 2010 and 11% of our bookings for the year ended December 31, 2012 and we may in the future increase sales to government entities. Sales into government entities are subject to a number of risks. Selling to government entities can be highly competitive, expensive and time consuming, often requiring significant upfront time and expense without any assurance that we will complete a sale. Accordingly:

could cause governments and governmental agencies to delay or refrain from purchasing the products and services that we offer in the future or otherwise have an adverse effect on our business, financial condition and results of operations.

16

Table of Contents

Most of our sales to government entities have been made indirectly through our channel partners. Government entities may have contractual or other legal rights to terminate contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our results of operations.

In addition, for purchases by the U.S. federal government, we must comply with laws and regulations relating to U.S. federal government contracting, which affect how we and our channel partners do business in connection with U.S. federal agencies. These laws and regulations may impose added costs on our business, and failure to comply with these or other applicable regulations and requirements, including non-compliance in the past, could lead to claims for damages from our channel partners, penalties, termination of contracts and suspension or debarment from government contracting for a period of time. Any such damages, penalties, disruption or limitation in our ability to do business with the U.S. federal government may adversely impact our results of operations.

Our business in countries with a history of corruption and transactions with foreign governments increase the risks associated with our international activities.

As we operate and sell internationally, we are subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties for the purpose of obtaining or retaining business. We have operations, deal with and make sales to governmental customers in countries known to experience corruption, particularly certain emerging countries in Africa, East Asia, Eastern Europe, South America and the Middle East. Our activities in these countries create the risk of unauthorized payments or offers of payments by one of our employees, consultants, sales agents or channel partners that could be in violation of various anti-corruption laws, even though these parties may not be under our control. While we have implemented safeguards to prevent these practices by our employees, consultants, sales agents and channel partners, our existing safeguards and any future improvements may prove to be less than effective, and our employees, consultants, sales agents or channel partners may engage in conduct for which we might be held responsible. Violations of the FCPA may result in severe criminal or civil sanctions, including suspension or debarment from U.S. government contracting, and we may be subject to other liabilities, which could negatively affect our business, operating results and financial condition.

We rely significantly on revenue from maintenance and support which may decline and, because we recognize revenue from such services over the term of the relevant service period, downturns or upturns in sales are not immediately reflected in full in our operating results.

Our maintenance and support revenue accounted for 33% of our total revenue for 2010, 31% of our total revenue for 2011 and 32% of our total revenue for 2012. Sales of new or renewal such services contracts may decline or fluctuate as a result of a number of factors, including customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors or reductions in our customers’ spending levels. If our sales of new or renewal services contracts decline, our revenue or revenue growth may decline and our business will suffer. In addition, we recognize service revenue ratably over the term of the relevant service period, which is typically one to three years but has been as long as five years. As a result, much of the revenue we report each quarter is the recognition of deferred revenue from services contracts entered into during previous quarters. Consequently, a decline in new or renewal services contracts in any one quarter will not be fully reflected in revenue in that quarter, but will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in new or renewed sales of our services would not be reflected in full in our results of operations until future periods.

If we are unable to increase sales to larger customers, our results of operations may suffer.

We continuously seek to increase sales of our products to large enterprises, managed security service providers and government entities. Sales to large enterprises, service providers and government entities involve risks that may not be present, or are present to a lesser extent, with sales to small to mid-sized entities. These risks include:

In addition, product purchases by enterprises, managed security service providers, cloud hosting providers and government entities are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. Large enterprises, managed security service providers, cloud hosting providers and government entities typically have longer implementation cycles; require greater product functionality and scalability and a broader range of services; demand that vendors take on a larger share of risks; sometimes require acceptance provisions that can lead to a delay in revenue recognition; and expect greater payment flexibility from vendors. All these factors can add risk to doing business with these customers. If our sales expectations for a large customer do not materialize in a particular quarter or at all, then our business, financial condition and results of operations could be materially and adversely affected.

Table of Contents

If our existing and potential customers migrate to hosted, cloud-based data centers that do not deploy our products, our revenues could suffer.

The majority of our current sales are made through a model in which our channel partners sell our business security solutions to large enterprise customers that operate their own data centers and have the ability to choose the business security solutions and configurations to fit their environment. If our large enterprise customers and potential customers choose to outsource the hosting of their data centers to large, multi-tenancy hosting providers like Rackspace Hosting, Inc. and Amazon.com, Inc., they may not be able to choose what business security solutions are deployed in these hosted environments, and our current sales model may not be effective. Although we work with large hosting services providers, like Rackspace Hosting, Inc. and Savvis, Inc., to integrate our business security solutions into their hosting environments so that our solutions may be offered to their hosting customers, we cannot guarantee that all such hosting service providers will adopt our solutions, offer them as a choice to their customers or promote our solutions over those of our competitors. Even if these large hosting services providers integrate our business security solutions into their hosting environments and promote our solutions, they may be able to negotiate larger discounts than individual enterprise customers and, consequently, the average selling price of our products may decrease and our revenue would suffer. Alternatively, they may offer services based on our competitors’ products at lower cost or bundled with other services that we do not offer, and their customers may choose those services even if they would otherwise chose our products if making a decision on a stand-alone basis.

If our customers are not satisfied with our technical support or professional services, they may choose not to purchase our products and services or to renew maintenance contracts, either of which would adversely impact our business and results of operations.

Our business relies on our customers’ satisfaction with the technical support and professional consulting services we provide to support our products. If we fail to provide technical support services that are responsive, satisfy our customers’ expectations and resolve issues that they encounter with our products and services, then they may elect not to purchase or renew annual maintenance and support contracts and they may choose not to purchase additional products and services from us. Accordingly, our failure to provide satisfactory technical support or professional services could have a material and adverse effect on our business and results of operations.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Our functional and reporting currency is the U.S. dollar and we generate a majority of our revenue in U.S. dollars. However, in 2011 and 2012, we incurred approximately 37% and 41%, respectively, of our expenses outside of the United States in foreign currencies, primarily Israeli shekels, principally with respect to salaries and related personnel expenses associated with our Israeli operations. The exchange rate between the U.S. dollar and foreign currencies has fluctuated substantially in recent years and may continue to fluctuate substantially in the future. We expect that a majority of our revenues will continue to be generated in U.S. dollars for the foreseeable future and that a significant portion of our expenses, including personnel costs, as well as capital and operating expenditures, will continue to be denominated in Israeli shekels. The results of our operations may be adversely affected by foreign exchange fluctuations.

We use forward foreign exchange contracts to hedge or mitigate the effect of changes in foreign exchange rates on our operating expenses denominated in certain foreign currencies. However, this strategy might not eliminate our exposure to foreign exchange rate fluctuations and involves costs and risks of its own, such as cash expenditures, ongoing management time and expertise, external costs to implement the strategy and potential accounting implications. Additionally, our hedging activities may contribute to increased losses as a result of volatility in foreign currency markets.

Our business and operations have experienced rapid growth, and if we do not appropriately manage any future growth, or are unable to improve our systems and processes, our operating results will be negatively affected.

We have experienced rapid growth over the last several years. For example, we grew from 315 employees as of December 31, 2010 to 383 employees as of December 31, 2011, and then to 474 employees as of December 31, 2012. This growth has placed, and will continue to place, a strain on our employees, management systems and other resources. Managing our growth will require significant expenditures and allocation of valuable management resources. We rely heavily on information technology systems to help manage critical functions, such as order processing, revenue recognition, financial forecasts and inventory and supply chain management. To manage any future growth effectively, we must continue to improve our information technology and financial infrastructure, operating and administrative systems and controls, and continue to manage headcount, capital and processes in an efficient manner. We may not be able to successfully implement improvements to these systems and processes in a timely or efficient manner. For instance, in the third quarter of 2011, we completed the implementation of NetSuite, an on-demand enterprise resource planning (“ERP”) system, replacing our prior ERP system. We have a limited operating history using NetSuite and may encounter difficulties using NetSuite to manage critical functions of our business.

18

Table of Contents

In addition, we rely heavily on hosted, Software-as-a-Service (“SaaS”) technologies from third parties in order to operate critical functions of our business, including ERP services from NetSuite and customer relationship management (“CRM”) services from salesforce.com, Inc. If these services become unavailable due to extended outages or interruptions or because they are no longer available on commercially reasonable terms or prices, our expenses could increase, our ability to manage our finances could be interrupted and our processes for managing sales of our products and services and supporting our customers could be impaired until equivalent services, if available, are identified, obtained and integrated; all of which could harm our business.

Also, our systems and processes may not prevent or detect all errors, omissions or fraud. Our failure to improve our systems and processes, or their failure to operate in the intended manner, may result in our inability to manage the growth of our business and to accurately forecast our revenue, expenses and earnings, or to prevent certain losses. Our productivity and the quality of our products and services may also be adversely affected if we do not integrate and train our new employees quickly and effectively. Any future growth would add complexity to our organization and require effective coordination across our organization. If we fail to achieve the necessary level of efficiency in our organization as it grows or with otherwise fail to manage any future growth effectively, we could incur in increased costs, and loss of customer and investor confidence in our internal systems and processes, any of which could result in harm to our business, results of operations and financial condition or a decline in our stock price.

Assertions by third parties of infringement or other violations by us of their intellectual property rights could result in significant costs and substantially harm our business and operating results.

Patent and other intellectual property disputes are common in the IT security industry. Some companies in the IT security industry, including some of our competitors, own large numbers of patents, copyrights, trademarks and trade secrets, which they may use to assert claims against us. This disparity between our patent portfolio and the patent portfolios of our most significant competitors may increase the risk that they may sue us for patent infringement and may limit our ability to counterclaim for patent infringement or settle through patent cross-licenses. In addition, there are also patent holding companies or other adverse patent owners who are solely or primarily in the business of building portfolios of patents and asserting them against operating companies, often with little merit, and who have no relevant product revenues and against whom potential assertions our patents (and potential patents) may provide little or no deterrence. Third parties have asserted and may in the future assert claims of infringement, misappropriation or other violations of intellectual property rights against us. For example, in May 2010, F5 Networks, Inc., an IT infrastructure company that competes with us in the web application firewall market, filed a lawsuit against us alleging patent infringement. In June 2010, we filed a counterclaim alleging patent infringement by F5 Networks, Inc. In February 2011, we entered into a settlement and license agreement with F5 Networks, Inc., which dismissed the litigation. Third parties may also assert such claims against our customers or channel partners whom we typically indemnify against claims that our products infringe, misappropriate or otherwise violate the intellectual property rights of third parties. As the numbers of products and competitors in our market increase and overlaps occur, claims of infringement, misappropriation and other violations of intellectual property rights may increase. Also, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited or divulged proprietary or other confidential information.

We cannot assure you that we are not infringing or otherwise violating any third-party intellectual property rights. Further, any claim of infringement, misappropriation or other violation of intellectual property rights by a third party, even those without merit, could be asserted against us, cause us to incur substantial costs defending against the claim and could distract our management from our business. An adverse outcome of a dispute may require us to pay substantial damages, including treble damages, if we are found to have willfully infringed a third party’s patents or copyrights; cease making, licensing or using solutions that are alleged to infringe or misappropriate the intellectual property of others; expend additional development resources to attempt to redesign our products or services or otherwise to develop non-infringing technology, which may not be successful; enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies or intellectual property rights; and indemnify our customers and partners. Royalty or licensing agreements, if required or desirable, may be unavailable on terms acceptable to us, or at all, and may require significant royalty payments and other expenditures. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. Any of these events could seriously harm our business, financial condition and results of operations.

We rely on the availability of licenses to third-party software and other intellectual property, the loss of which could increase our costs and delay software shipments.

Many of our products and services include software or other intellectual property licensed from third parties, and we also use software and other intellectual property licensed from third parties in our business. This exposes us to risks over which we may have little or no control. For example, a licensor may have errors or defects in its products that harm our business, may have difficulties keeping up with technological changes or may stop supporting the software or other intellectual property that it licenses to us. Also, it will be necessary in the future to renew licenses, expand the scope of existing licenses or seek new licenses, relating to various aspects of these products and services, or otherwise relating to our business, which may result in increased license fees. In addition, a direct or indirect licensor may assert that we or our customers are in breach of the terms of a license, which could, among other things, give such licensor the right to terminate a license or seek damages from us, or both. Moreover, the inclusion in our products and services of software or other intellectual property licensed from third parties on a nonexclusive basis could limit our ability to differentiate our products from those of our competitors.

Licensed software may not continue to be available on commercially reasonable terms, or at all. While we believe that there are currently adequate replacements for third-party software, any loss of the right to use any of this software could result in delays in producing or delivering our software until equivalent technology is identified and integrated, which delays could harm our business. Our business would be disrupted if any of the software we license from others or functional equivalents of this software were either no longer available to us or no longer offered to us on commercially reasonable terms. In either case, we would be required to either redesign our products to function with software available from other parties or to develop these components ourselves, which would result in increased costs and could result in delays in our product shipments and the release of new product offerings. Furthermore, we might be forced to limit the features available in our current or future products. If we fail to maintain or renegotiate any of these software licenses, we could face significant delays and diversion of resources in attempting to license and integrate a functional equivalent of the software. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

Some of our products contain “open source” software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our business.

Certain of our products are distributed with software licensed under “open source” licenses. Some of these licenses contain requirements that we make available source code for modifications or derivative works we create based upon the open source software, and that we license these modifications or derivative works under the terms of a particular open source license or subject to certain license requirements. If we combine our proprietary software with open source software in a certain manner, we could, under certain provisions of the open source licenses, be required to release the source code of our proprietary software. In addition to risks related to license requirements, usage of open source software can subject us to greater risks than use of third-party commercial software, as licensors of open source software generally do not provide warranties or any indemnification for infringement of third party intellectual property rights. We have established processes to help alleviate these risks, including a review process for screening requests from our development organization for the use of open source software, but we cannot be sure that all open source software is submitted for approval prior to use in our products. In addition, open source license terms may be ambiguous and many of the risks associated with use of open source software cannot be eliminated, and could, if not properly addressed, negatively affect our business. If we were found to have inappropriately used open source software, we might be required to re-engineer our products, to release proprietary source code, to discontinue the sale of our products in the event re-engineering could not be accomplished on a timely basis or to take other remedial action that may divert resources away from our development efforts, any of which could adversely affect our business, operating results and financial condition. Disclosing the source code of our proprietary software could make it easier for malicious third parties to discover vulnerabilities in our business security products and allow our competitors to create similar products with decreased development effort and time. Any of these events could have a material adverse effect on our reputation, business, financial condition and results of operations.

Failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results.

Our success depends, in part, on our ability to protect proprietary methods and technologies that we develop under the intellectual property laws of the United States and other countries, so that we can prevent others from using our inventions and proprietary information. We attempt to protect our intellectual property under patent, trademark, copyright and trade secret laws, and through a combination of confidentiality procedures, contractual provisions and other methods, all of which offer only limited protection. If we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology, and our business might be harmed. In addition, defending our intellectual property rights might entail significant expenses. Any of our patents, copyrights, trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. We have eight issued patents and nine patent applications pending in the United States. Our issued patents, which are limited in number compared to some of our competitors, may not provide us with any competitive advantages or may be challenged by third parties, and our patent applications may never be granted at all. Additionally, the process of obtaining patent

20

Table of Contents

protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. Further, for strategic and other reasons we may choose not to seek patent protection for certain innovations and may choose not to pursue patent protection in certain jurisdictions. Even if issued, there can be no assurance that our patents will adequately protect our intellectual property, as the legal standards relating to the validity, enforceability and scope of protection of patent and other intellectual property rights are uncertain.

Any patents that are issued may subsequently be invalidated or otherwise limited, enabling other companies to better develop products that compete with ours, which could adversely affect our competitive business position, business prospects and financial condition. In addition, issuance of a patent does not guarantee that we have a right to practice the patented invention. Patent applications in the U.S. are typically not published until 18 months after filing, or in some cases not at all, and publications of discoveries in industry-related literature lag behind actual discoveries. We cannot be certain that we were the first to make the inventions claimed in our issued patents or pending patent applications or otherwise used in our products, that we were the first to file for protection in our patent applications, or that third parties do not have blocking patents that could be used to prevent us from marketing or practicing our patented products or technology. Effective patent, trademark, copyright and trade secret protection may not be available to us in every country in which our products and services are available. The laws of some foreign countries may not be as protective of intellectual property rights as those in the United States, and mechanisms for enforcement of intellectual property rights may be inadequate. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property.

We might be required to spend significant resources to monitor and protect our intellectual property rights. We may initiate claims or litigation against third parties for infringement of our proprietary rights or to establish the validity of our proprietary rights. Any litigation, whether or not it is resolved in our favor, could result in significant expense to us and divert the efforts of our technical and management personnel, which may adversely affect our business, operating results and financial condition.

Confidentiality agreements with partners, employees, consultants and others may not adequately prevent disclosure of trade secrets and other proprietary information.

In order to protect our proprietary technology, processes and methods, we rely in part on confidentiality agreements and other restrictions with our customers, partners, employees, consultants and others. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Despite our efforts to protect our proprietary technology, processes and methods, unauthorized parties may attempt to misappropriate, reverse engineer or otherwise obtain and use them. We may be unable to determine the extent of any unauthorized use or infringement of our products, technologies or intellectual property rights In addition, others may independently discover trade secrets and proprietary information, and in these cases we would not be able to assert any trade secret rights against those parties. Moreover, policing unauthorized use of our technologies, products and intellectual property is difficult, expensive and time-consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property rights may be weak. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

Conditions in Israel may limit our ability to develop and sell our products. This could result in a decrease of our revenues.

Our principal research and development facilities are located in Israel. Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its neighboring countries, as well as incidents of civil unrest, and a number of state and non-state actors have publicly committed to its destruction. Political, economic and military conditions in Israel could directly affect our operations. We could be adversely affected by any major hostilities involving Israel, including acts of terrorism or any other hostilities involving or threatening Israel, the interruption or curtailment of trade between Israel and its trading partners, a significant increase in inflation or a significant downturn in the economic or financial condition of Israel. Any on-going or future violence between Israel and the Palestinians, armed conflicts, terrorist activities, tension along the Israeli borders or with other countries in the region, including Iran, or political instability in the region could disrupt international trading activities in Israel and may materially and negatively affect our business and could harm our results of operations.

Certain countries, as well as certain companies and organizations, continue to participate in a boycott of Israeli firms, firms with large Israeli operations and others doing business with Israel and Israeli companies. We are also precluded from marketing our products to certain of these countries due to United States regulatory restrictions. In addition, such boycott, restrictive laws, policies or practices may change over time in unpredictable ways, and could, individually or in the aggregate, have a material adverse affect on our business in the future.

Some of our employees in Israel, including one of our executive officers, are obligated to perform annual military reserve duty in the Israel Defense Forces, depending on their age and position in the armed forces. Furthermore, they may be called to active reserve duty at any time under emergency circumstances for extended periods of time. For example, in 2012, approximately 50 of our employees in Israel were called for active reserve duty, each serving for an average of approximately one and one half weeks. Our operations could be disrupted by the absence, for a significant period, of one or more of our executive officers or key employees due to military service, and any significant disruption in our operations could harm our business.

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

We depend on the continued contributions of our senior management and other key employees to execute on our business plan, and to identify and pursue new opportunities and product innovations. The loss of services of senior management or other key employees, particularly Shlomo Kramer, one of our founders and our President and Chief Executive Officer; Amichai Shulman, one of our founders and our Chief Technology Officer; and Terrence J. Schmid, our Chief Financial Officer and Treasurer, could significantly delay or prevent the achievement of our development and strategic objectives.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled technical, managerial, finance and other personnel, particularly in our sales and marketing, research and development and professional service departments. Any of our employees may terminate their employment at any time. Competition for highly skilled personnel is frequently intense, especially in the San Francisco Bay Area and in Tel Aviv, Israel, the locations in which we have a substantial presence and need for highly-skilled personnel. We may be unable to attract and retain suitably qualified individuals who are capable of meeting our growing technical, operational and managerial requirements, on a timely basis or at all, and we may be required to pay increased compensation in order to do so. If we are unable to attract and retain the qualified personnel we need to succeed, our business would suffer.

Volatility or lack of performance in our stock price may also affect our ability to attract and retain our key employees. Many of our senior management personnel and other key employees have become, or will soon become, vested in a substantial amount of stock or stock options. Employees may be more likely to leave us if the shares they own or the shares underlying their vested options have significantly appreciated in value relative to the original purchase prices of the shares or the exercise prices of the options, or if the exercise prices of the options that they hold are significantly above the market price of our common stock. If we are unable to retain our employees, our business, operating results and financial condition would be harmed.

Our internal network system and website may be subject to intentional disruption that could adversely impact our reputation and future sales.

Because we are a leading provider of business security products, “hackers” and others may try to access our data or compromise our systems. Similarly, experienced computer programmers may attempt to penetrate our network security or the security of our website and cause interruptions of our services. Because the techniques used by such computer programmers to access or sabotage networks change frequently and may not be recognized until launched against a target, we may be unable to anticipate these techniques. The theft and/or unauthorized use or publication of our trade secrets and other confidential business information as a result of such an event could adversely affect our competitive position, reputation, brand and future sales of our products, and could impair our ability to operate our business, including our ability to provide subscription or maintenance and support services to our customers. We could suffer monetary and other losses and reputational harm in the event of such incidents.

Outages, interruptions or delays in hosting services could impair the delivery of our cloud-based security services and harm our business.

We operate infrastructure that supports our ThreatRadar and Security Operations Center (“SOC”) services and use third party hosting facilities for certain ThreatRadar services. Despite precautions taken within our own internal network and at these third party facilities, the occurrence of a natural disaster or an act of terrorism or other unanticipated problems could result in lengthy interruptions in our services.

The cloud-based security services that we provide through our majority owned subsidiary, Incapsula, are operated from a network of third party facilities that host the software and systems that operate these security services. Any damage to, or failure of, our internal systems or systems at third party hosting facilities could result in outages or interruptions in our cloud-based services. Outages or interruptions in our cloud-based security services may cause our customers and potential customers to believe our cloud-based security services are unreliable, cause us to issue credits or pay penalties, cause customers to terminate their subscriptions and adversely affect our renewal rates and our ability to attract new customers, ultimately harming our business and revenue.

Our success in acquiring and integrating other businesses, products or technologies could impact our financial position.

In order to remain competitive, we may seek to acquire additional businesses, products or technologies, any of which could be material to our business, operating results and financial condition. The environment for acquisitions in the markets in which we operate is very competitive and acquisition candidate purchase prices will likely exceed what we would prefer to pay, but may choose to pay in order to make an acquisition. Furthermore, we may not find suitable acquisition candidates, and acquisitions we complete may be unsuccessful. Achieving the anticipated benefits of future acquisitions will depend in part upon whether we can integrate acquired operations, products and technology in a timely and cost-effective manner.

22

Table of Contents

Acquisitions involve many risks, including the following:

If we are unable to effectively execute acquisitions, our business, financial condition and results of operations could be adversely affected.

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.

Our products incorporate encryption technology and may be exported outside the U.S. only if we obtain an export license or qualify for an export license exception. Compliance with applicable regulatory requirements regarding the export of our products may prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the export of our products to some countries altogether. Further, various countries regulate the import of encryption technology and our appliance-based products and have enacted laws that could limit our ability to distribute products, could create delays in the introduction of our products in those countries or could limit our customers’ ability to implement our products in those countries. Any new export or import restrictions, new legislation or shifting approaches in the enforcement or scope of existing regulations, or in the countries, persons or technologies targeted by such regulations, could result in decreased use of our products by existing customers with international operations, declining adoption of our products by new customers with international operations and decreased revenues. If we, or our channel partners, fail to comply with export and import regulations, we may be denied export privileges, be subjected to fines or other penalties and our products may be denied entry into other countries, as well as potentially suffering reputational harm.

Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products to U.S. embargoed or sanctioned countries, governments and persons. While we take precautions to prevent our product from being shipped to U.S. sanctions targets, our products could be shipped to those targets by our channel partners despite our efforts. Any such shipment could have negative consequences including government investigations, penalties and reputational harm. Any change in economic sanctions or related legislation, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. Any limitation on our ability to export or sell our products would likely adversely affect our business, financial condition and results of operations.

Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.

We are subject to income taxation in the United States and numerous foreign jurisdictions. Determining our provision for income taxes requires significant management judgment. In addition, our provision for income taxes is subject to volatility and could be adversely affected by many factors, including, among other things, changes to our operating or holding structure, changes in the amounts of earnings in jurisdictions with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities and changes in tax laws. We are subject to ongoing tax examinations in various jurisdictions. Tax authorities may disagree with our intercompany charges, cross-jurisdictional transfer pricing or other matters and assess additional taxes. While we regularly assess the likely outcomes of these examinations to determine the adequacy of our provision for income taxes, there can be no assurance that the outcomes of such examinations will not have a material impact on our operating results and cash flows.

Significant judgment is required to determine the recognition and measurement attributes prescribed in Accounting Standards Codification (“ASC”) 740-25 (formerly referred to as Financial Interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109”). In addition, ASC 740-25 applies to all income tax positions, including the potential recovery of previously paid taxes, which if settled unfavorably could adversely impact our provision for income taxes or additional paid-in capital. In addition, we are subject to the continuous examination of our income tax returns by the U.S. Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our results of operations.

Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events, and to interruption by manmade problems such as terrorism.

A significant natural disaster, such as an earthquake, fire or a flood, or a significant power outage could have a material adverse impact on our business, financial condition and results of operations. Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity, on land reclaimed from the bay that is susceptible to high liquefaction risk in the case of an earthquake. In addition, natural disasters could affect our manufacturing vendors or logistics providers’ ability to perform services such as manufacturing products on a timely basis and assisting with shipments on a timely basis. In the event our service providers’ information technology systems or manufacturing or logistics abilities are hindered by any of the events discussed above, shipments could be delayed, resulting in missing financial targets, such as revenue and shipment targets, for a particular quarter. Further, if a natural disaster occurs in a region from which we derive a significant portion of our revenue, customers in that region may delay or forego purchases of our products, which may materially and adversely impact our results of operations for a particular period. In addition, acts of terrorism could cause disruptions in our business or the business of our manufacturer, logistics providers, partners, customers or the economy as a whole. Given our typical concentration of sales at each quarter end, any disruption in the business of our manufacturer, logistics providers, partners or customers that impacts sales at the end of our quarter could have a significant adverse impact on our quarterly results. All of the aforementioned risks may be augmented if the business continuity plans for us and our suppliers prove to be inadequate. To the extent that any of the above results in delays or cancellations of customer orders, or the delay in the manufacture, deployment or shipment of our products, our business, financial condition and results of operations would be adversely affected.

Risks Related to Ownership of our Common Stock

Market volatility may affect our stock price and the value of your investment

The trading prices of the securities of technology companies have been highly volatile. The market price of our common stock may fluctuate significantly in response to a number of factors, most of which we cannot predict or control, including:

In addition, the stock market in general, and the New York Stock Exchange in particular, have experienced substantial price and volume volatility that is often seemingly unrelated to the operating performance of particular companies. These broad market fluctuations may cause the trading price of our common stock to decline. In the past, securities class action litigation has often been brought against a company after a period of volatility in the market price of its common stock. We may become involved in this type of litigation in the future. Any securities litigation claims brought against us could result in substantial expenses and the diversion of our management’s attention from our business.

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

As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the rules and regulations of the New York Stock Exchange. We expect that the requirements of these rules and regulations will continue to increase our legal, accounting and financial compliance costs, make some activities more difficult, time-consuming and costly and place strains on our personnel, systems and resources.

24

Table of Contents

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC’s rules and forms. Our current controls and any new controls that we develop may become inadequate because of changes in conditions, and the degree of compliance with the policies or procedures may deteriorate. In addition, weaknesses in our internal controls over financial reporting may be discovered in the future. Our filings with the SEC are subject to periodic review by the SEC, and our auditors are subject to periodic review by the Public Company Accounting Oversight Board (PCAOB). Any failure to develop or maintain effective controls over financial reporting, any difficulties encountered in their implementation or improvement, or any issues that emerge as a result of regulatory review, could harm our operating results or cause us to fail to meet our reporting obligations and may result in a revision or restatement of our prior period financial statements. Any failure to implement and maintain effective internal controls also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we are required to include in our annual reports filed with the SEC under Section 404 of the Sarbanes-Oxley Act. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock.

In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources and provide significant management oversight, which involve substantial accounting-related costs. Any failure to maintain the adequacy of our internal controls, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. In the event that we are not able to continue to demonstrate compliance with Section 404 of the Sarbanes-Oxley Act in a timely manner, that our internal controls are perceived as inadequate or that we are unable to produce timely or accurate financial statements, investors may lose confidence in our operating results and our stock price could decline. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the New York Stock Exchange.

We also have implemented elements of a disaster recovery/business continuity plan for our accounting and related information technology systems but we have not yet implemented a complete disaster recovery/business continuity plan. If the elements that we have developed and plan to develop in the future prove inadequate in the circumstances of a particular disaster or other business continuity event our ability to maintain timely accounting and reporting may be materially impaired.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If we do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the value of their stock.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our restated certificate of incorporation and amended and restated bylaws may delay or prevent an acquisition of us or a change in our management. These provisions include:

25

Table of Contents

In addition, because we are incorporated in Delaware, we are governed by the provisions of the anti-takeover provisions of the Delaware General Corporation Law, which may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board were considered beneficial by some stockholders. In addition, 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.

Further, as of March 1, 2013 our directors and executive officers, together with their affiliates, beneficially own in the aggregate 18.3% of our outstanding common stock (including options exercisable by those holders within 60 days of that date). Holders that together with their affiliates, hold 5% or more of our outstanding common stock, but who are not affiliated with our directors and executive officers, beneficially own in the aggregate an additional 16.4% of our outstanding common stock as of March 1, 2013, based on information in their public filings. As a result, our directors and officers and their affiliates, collectively, or our largest stockholders, acting together, may be able to impede a merger, consolidation or sale of all or substantially all of our assets.

Our ability to use our net operating loss carryforwards may be subject to limitation and may result in increased future tax liability to us.

Generally, a change of more than 50% in the ownership of a corporation’s stock, by value, over a three-year period constitutes an ownership change for U.S. federal income tax purposes. An ownership change may limit a company’s ability to use its net operating loss carryforwards attributable to the period prior to such change. We have not performed a detailed analysis to determine whether an ownership change under Section 382 of the Internal Revenue Code has occurred after each of our previous private placements of preferred stock or after the issuance of shares of common stock in connection with our initial public offering. In the event we have undergone an ownership change under Section 382, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards to offset U.S. federal taxable income may become subject to limitations, which could potentially result in increased future tax liability to us.
