RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below and all other information contained in this prospectus before deciding whether to purchase shares of our common stock. Our business, prospects, financial condition or operating results could be materially adversely affected by any of these risks, as well as other risks not currently known to us or that are currently considered immaterial. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment. In assessing these risks, you should also refer to the other information contained in this prospectus, including our consolidated financial statements and related notes, before deciding to purchase any shares of our common stock.

Risks Related to Our Business

We have had a history of losses and we may be unable to achieve or sustain profitability.

We experienced a net loss of $26.4 million and $16.8 million in 2013 and 2012, respectively, and a net loss of $12.1 million in the six months ended June 30, 2014. We cannot predict if we will achieve profitability in the near future or at all. We expect to make significant future expenditures to develop and expand our business. Our recent growth in revenue may not be sustainable, and we might not achieve sufficient revenue to achieve or maintain profitability. We may incur significant losses in the future for a number of reasons, including the other risks described in this prospectus, and we may encounter unforeseen expenses, difficulties, complications and delays and other unknown events. Accordingly, we may not be able to achieve or maintain profitability, and we may incur significant losses for the foreseeable future.

Failure to manage our growth effectively could increase our expenses, decrease our revenue and prevent us from implementing our business strategy.

We have been experiencing a period of growth, which puts strain on our business. To manage this and our anticipated future growth effectively, we must continue to maintain and enhance our information technology infrastructure, financial and accounting systems and controls. We also must attract, train and retain a significant number of qualified software engineers, technical and management personnel, sales and marketing personnel, customer support personnel and professional services personnel. Failure to effectively manage our rapid growth could lead us to over-invest or under-invest in development and operations, result in weaknesses in our infrastructure, systems or controls, give rise to operational mistakes, losses, loss of productivity or business opportunities and result in loss of employees and reduced productivity of remaining employees. Our growth could require significant capital expenditures and might divert financial resources from other projects such as the development of new products and services. If our management is unable to effectively manage our growth, our expenses might increase more than expected, our revenue could decline or might grow more slowly than expected, and we might be unable to implement our business strategy. The quality of our products and services might suffer, which could negatively affect our reputation and harm our ability to retain and attract customers.

The market for health insurance exchanges in the United States is relatively undeveloped, rapidly evolving and volatile, which makes it difficult to forecast adoption rates and demand for our solutions. If the market does not develop or develops more slowly than we expect, or if individuals, brokers or health plans select more traditional or alternative channels for the purchase and sale of health insurance, it could have a material adverse effect on our business and results of operations.

The market for health insurance exchanges in the United States is relatively undeveloped, rapidly evolving and volatile. Accordingly, our future financial performance will depend in part on growth in this market and on our ability to adapt to emerging demands and trends in this market. Demand for our exchange solutions has been driven in large part by recent regulatory changes, broader use of the Internet, shifts from group plans to the purchase of individual plans and advances in technology. It is difficult to predict with any precision adoption

rates or the future growth rate and size of our target market. The market for health insurance sales automation software is relatively new and unproven, and it is uncertain whether it will achieve and sustain high levels of demand and market acceptance. The volatility and rapidly evolving nature of the market in which we operate, as well as other factors that are beyond our control, reduces our ability to accurately evaluate our long-term outlook and forecast annual performance.

Additionally, our success depends in part upon widespread individual and health plan acceptance of the Internet as a shopping platform and marketplace for the purchase and sale of health insurance. Individuals, employers, employees and health plans may choose to depend on more traditional sources, such as individual agents, or alternative sources may develop, including as a result of significant reforms to healthcare legislation through the Patient Protection and Affordable Care Act, or PPACA, and the Healthcare and Education Reconciliation Act of 2010, or HCERA, which we refer to collectively as Healthcare Reform.

A reduction in demand for health insurance exchanges caused by lack of acceptance, technological challenges, competing solutions or as a result of individuals, brokers or health plans determining that other distribution channels for health insurance are superior to ours would have a material adverse effect on our business, growth, results of operations and financial condition.

Our estimate of the market size for our solutions may prove to be inaccurate, and even if the market size is accurate, we cannot assure you that our business will serve a significant portion of the market.

Our estimate of the market size for our solutions is subject to significant uncertainty and is based on assumptions and estimates, including our internal analysis and industry experience, which may not prove to be accurate. Our ability to serve a significant portion of this estimated market is subject to many factors, including our success in implementing our business strategy, which is subject to many risks and uncertainties. Accordingly, even if our estimate of the market size is accurate, we cannot assure you that our business will serve a significant portion of this estimated market for our solutions.

We operate in the highly competitive software industry. If we are not able to compete effectively, our business and operating results will be harmed.

The software market is highly competitive and is likely to attract increased competition, which could make it hard for us to succeed. Small, specialized providers continue to become more sophisticated and effective. In addition, large, well-financed, and technologically sophisticated software companies might focus more on our market. The size and financial strength of these entities is increasing as a result of continued consolidation in both the IT and health insurance industries. We expect large integrated software companies to become more active in our market, both through acquisitions and internal investment. As costs fall and technology improves, increased market saturation might change the competitive landscape in favor of our competitors.

Some of our current competitors have greater name recognition, longer operating histories, and significantly greater resources than we do. As a result, our competitors might be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards, or customer requirements. In addition, current and potential competitors have established, and might in the future establish, cooperative relationships with vendors of complementary products, technologies, or services to increase the availability of their products in the marketplace. Accordingly, new competitors or alliances might emerge that have greater market share, a larger customer base, more widely adopted proprietary technologies, greater marketing expertise, greater financial resources and larger sales forces than we have, which could put us at a competitive disadvantage. Further, in light of these advantages, even if our products and services are more effective than those of our competitors, current or potential customers might accept competitive offerings in lieu of purchasing our offerings. Increased competition is likely to result in pricing pressures, which could negatively impact our sales, profitability or market share. In addition to new niche vendors, who offer stand-alone products and services, we face competition from existing enterprise vendors, including those currently focused on software solutions that have information systems in

15

Table of Contents

place with potential customers in our target market. These existing enterprise vendors might promise products or services that offer ease of integration with existing systems and which leverage existing vendor relationships. In addition, large health plans often have internal technology staffs and proprietary software for benefits and distribution management, making them less likely to buy our solutions.

If our existing customers do not continue or renew their agreements with us, renew at lower fee levels or decline to license additional software or purchase additional applications and services from us, it could have a material adverse effect on our business and operating results.

We derive a significant portion of our revenue from renewal of existing customer agreements and sales of additional software and services to existing customers and expect to continue to do so. As a result, achieving a high renewal rate of our customer agreements and selling additional software and services is critical to our future operating results.

We generally sell our software and services pursuant to agreements for terms of multiple years. Our customers may choose not to renew these contracts after the initial contract period expires. Additionally, some of our customers are able to terminate their respective contracts without cause or for convenience at any time. We may not be able to accurately predict future trends in customer renewals, and our customers’ renewal rates may decline or fluctuate. Without the continuance or renewal of our customer contracts our business and operating results may suffer.

Factors that may affect the renewal rate for our existing contracts, and our ability to sell additional applications and services, include:

If any of our customers terminate or do not renew their contracts for our services, renew on less favorable terms, or do not purchase additional functionality or software, our revenue may grow more slowly than expected or decline, and our profitability and gross margins may be harmed.

A significant amount of our revenue is derived from a limited number of customers, and any reduction in revenue from any of these customers could have a material adverse effect on our business.

Our ten largest customers by revenue in the past two years accounted for approximately 49.1% and 71.8% of our consolidated revenue in 2013 and 2012, respectively, and 56.1% of our revenue in the first six months of 2014. Our largest customer by revenue in the past two years, Blue Cross and Blue Shield of Michigan, accounted for approximately 9.6% and 21.3% of our revenue in 2013 and 2012, respectively, and 10.1% of our revenue in the first six months of 2014. If any of our key customers decides not to renew its contracts with us, or to renew on less favorable terms, our business, revenue, reputation, and our ability to obtain new customers could be materially and adversely affected.

We have experienced quarterly fluctuations, and expect to continue to experience quarterly fluctuations, in our operating results due to a number of factors, including the seasonality of our revenue, the sales and implementation cycles for our products and services and other factors, that make our future results difficult to predict and could cause our operating results to fall below expectations.

Our business is subject to seasonal fluctuations and our operating results are traditionally strongest in the fourth quarter of each year as a result of the open enrollment period established by PPACA. Therefore, our stock price might be based on expectations of future performance that we might not meet and, if our revenue or operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially.

The sales cycle for our products and services can vary from, on average, two to four months for our cloud-based solutions, and from four to 12 or more months for our enterprise solutions, from initial contact to contract execution. After a customer contract is signed, we provide an implementation process for the customer which typically ranges from two to four months for our cloud-based implementations and from three to 15 months for complex enterprise implementations, each from contract execution to completion of implementation. As a result, the period of time between contract signing and recognition of associated revenue may be lengthy, and we are not able to predict with certainty the period in which implementation will be completed.

During the sales and implementation cycles for our enterprise segments, we expend substantial time and effort, and incur significant additional operating expenses, but accounting principles do not allow us to recognize the resulting revenue until implementation is complete and the services are available for use by our customers, at which time we begin recognition of implementation revenue over the life of the contract or the expected life of the customer relationship, whichever is longer. Unanticipated difficulties and delays in implementation might arise as a result of failure by us or our customers to complete one or more of our or their respective responsibilities and, if implementation periods are extended or implementations are cancelled, revenue recognition could be delayed or fail to occur.

Our operating results have varied in the past. In addition to the other risk factors listed in this section, some of the important factors that may cause fluctuations in our quarterly operating results include:

In addition, a significant portion of our operating expense is relatively fixed in nature, and planned expenditures are based in part on expectations regarding future revenue. Accordingly, unexpected revenue shortfalls might decrease our gross margins and could cause significant changes in our operating results from quarter to quarter. If this occurs, the trading price of our common stock could fall substantially, either suddenly or over time.

In the event that our proprietary software does not operate properly, our reputation would suffer, claims would likely be asserted against us, and we would likely be required to divert our resources from other purposes, any of which could have a material adverse effect on our business.

Proprietary software development is time-consuming, expensive and complex. We may experience difficulties with software development, industry standards, design or marketing that could delay or prevent the development, introduction, or implementation of new solutions and enhancements. If our solutions do not function reliably or fail to achieve customer expectations in terms of performance, customers could assert liability claims against us and/or attempt to cancel their contracts with us. This could damage our reputation and impair our ability to attract or maintain customers.

Moreover, software as complex as ours has in the past contained, and may in the future contain, or develop, undetected defects or errors. Material performance problems or defects in our products and services might arise in the future. Errors might result from the interface of our services with legacy systems and data, which we did not develop and the function of which is outside of our control. Defects or errors might arise in our existing or new software or service processes. Because changes in health plan and legal requirements and practices relating to health insurance are frequent, we are continuously discovering defects and errors in our software and service processes compared against these requirements and practices. These defects and errors and any failure by us to identify and address them could result in loss of enrollment by our customers, loss of revenue or market share, liability to customers or others, failure to achieve market acceptance or expansion, diversion of development and other resources, injury to our reputation, and increased service and maintenance costs. Defects or errors in our product or service processes might discourage existing or potential customers from purchasing services from us. Correcting defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors or in responding to resulting claims or liability might be substantial and could adversely affect our operating results.

Our customers might assert claims against us in the future alleging that they suffered damages due to a defect, error, or other failure of our product or service processes. A claim could subject us to significant legal defense costs and adverse publicity regardless of the merits or eventual outcome of such claim.

If our transition from our current technology platforms to new platforms does not occur rapidly or as efficiently as anticipated, it could have a material adverse effect on our business and results of operations.

We are expanding our cloud-based software-as-a-service, or SaaS, offerings, including building new shared capabilities such as consumer shopping and personalization. Our ability to (i) complete that development and (ii) efficiently transition existing enterprise-platform customers to new cloud-based components is important to our future operating results. We are also investing in platform delivery improvements that will lower our cost of implementation and configuration and improve competitiveness. Our SaaS business model depends heavily on achieving economies of scale because the initial upfront investment is costly and the associated revenue is recognized on a ratable basis. If we fail to achieve efficient transitions, improvements to our capabilities, appropriate economies of scale or if we fail to manage or anticipate the evolution and demand of the SaaS pricing model, then our business and operating results will be adversely affected.

If we do not continue to provide innovative products and services, along with high quality support services, that are useful to our customers and consumers of insurance products, we might not remain competitive and our newer solutions may not be adopted by new and existing customers, which would have a material adverse effect on our business and results of operations.

Our success depends in part on our ability to successfully develop and sell innovative products and services that health insurance plans and brokers and their customers will utilize. We must continue to invest significant resources in research and development in order to enhance our existing products and services and introduce new high quality products and services that customers will want. If we are unable to predict preferences of our

18

Table of Contents

customers or consumers or industry changes, or if we are unable to modify our products and services on a timely basis, we might lose customers. Our operating results would also suffer if our innovations are not responsive to the needs of our customers, are not appropriately timed with market opportunity, or are not effectively brought to market. As technology continues to develop, our competitors might be able to offer results that are, or that are perceived to be, substantially similar to or better than those generated by us. This would force us to compete on additional product and service attributes and to expend significant resources in order to remain competitive.

Our success also depends on providing high quality support services to resolve any issues related to our products and services. High quality education and customer support are important for the successful marketing and sale of our products and services and for the renewal of existing customers. If we do not help our customers quickly resolve issues and provide effective ongoing support, our ability to sell additional products and services to existing customers would suffer and our reputation with existing or potential customers would be harmed.

We rely on data center providers, Internet infrastructure, bandwidth providers, third-party computer hardware and software, other third parties, and our own systems for providing services to our customers, and any failure of or interruption in the services provided by these third parties or our own systems could expose us to litigation and may negatively impact our relationships with customers, adversely affecting our brand and our business.

We currently serve our customers from two data centers, one located in Atlanta, Georgia and the other located in El Segundo, California. While we control and have access to our servers, we do not control the operation of these facilities. The owners of our data center facilities have no obligation to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew these agreements on commercially reasonable terms, or if one of our data center operators is acquired, we may be required to transfer our servers and other infrastructure to new data center facilities, and we may incur significant costs and possible service interruption in connection with doing so. Problems faced by our third-party data center locations, with the telecommunications network providers with whom we or they contract, or with the systems by which our telecommunications providers allocate capacity among their customers, including us, could adversely affect the experience of our customers. Our third-party data centers operators could decide to close their facilities without adequate notice. In addition, any financial difficulties, such as bankruptcy faced by our third-party data centers operators or any of the service providers with whom we or they contract may have negative effects on our business, the nature and extent of which are difficult to predict.

In addition, our ability to deliver our web-based services depends on the development and maintenance of the infrastructure of the Internet by third parties. This includes maintenance of a reliable network backbone with the necessary speed, data capacity, bandwidth capacity and security. Our services are designed to operate without interruption in accordance with our service level commitments. However, we have experienced and expect that we will experience future interruptions and delays in services and availability from time to time. In the event of a catastrophic event with respect to one or more of our systems, we may experience an extended period of system unavailability, which could negatively impact our relationship with customers. To operate without interruption, both we and our service providers must guard against:

We also rely on purchased or leased computer hardware and software licensed from third parties in order to offer our services. These licenses are generally commercially available on varying terms. However, it is possible

19

Table of Contents

that this hardware and software might not continue to be available on commercially reasonable terms, or at all. Any loss of the right to use any of this hardware or software could result in delays in the provisioning of our services until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated.

We exercise limited control over third-party vendors, which increases our vulnerability to problems with technology and information services they provide. Interruptions in our network access and services might in connection with third-party technology and information services reduce our revenue, cause us to issue refunds to customers for prepaid and unused subscription services, subject us to potential liability, or adversely affect our renewal rates. Although we maintain insurance for our business, the coverage under our policies might not be adequate to compensate us for all losses that may occur. In addition, we might not be able to continue to obtain adequate insurance coverage at an acceptable cost, if at all.

Various events could interrupt customers’ access to our platform, exposing us to significant costs.

The ability to access our platform is critical to our customers. Our operations and facilities are vulnerable to interruption and/or damage from a number of sources, many of which are beyond our control, including, without limitation: (i) power loss and telecommunications failures, (ii) fire, flood, hurricane, and other natural disasters, (iii) software and hardware errors, failures or crashes in our own systems or in other systems, (iv) computer viruses, denial-of-service attacks, hacking and similar disruptive problems in our own systems and in other systems, and (v) civil unrest, war, and/or terrorism. We have implemented various measures to protect against interruptions of customers’ access to our platform. If customers’ access is interrupted because of problems in the operation of our facilities, we could be exposed to significant claims by customers. Our plans for disaster recovery and business continuity rely on third-party providers of related services. If those vendors fail us at a time when our systems are not operating correctly, we could incur a loss of revenue and liability for failure to fulfill our obligations. Any significant instances of system downtime could negatively affect our reputation and ability to retain customers and sell our services, which would adversely impact our revenue.

If our security measures are breached or fail, and unauthorized persons gain access to customers’ and consumers’ data, our products and services might be perceived as being unsecure, customers and consumers might curtail or stop using our products and services, and we might incur significant liabilities.

Our products and services involve the collection, processing, storage and transmission of customers’ and consumers’ confidential information, which may include sensitive individually identifiable information that is subject to stringent statutory and regulatory obligations. Because of the sensitivity of this information, security features of our software and applications are very important. From time to time we may detect vulnerabilities in our systems, which, even if they do not result in a security breach, may reduce customer confidence and require substantial resources to address. If our security measures or those of our third-party service providers are breached or fail and/or are bypassed as a result of third-party action, employee error, malfeasance, or otherwise, someone might be able to obtain unauthorized access to our customers’ confidential information and/or patient data. As a result, our reputation could be damaged, our business might suffer, and we could face damages for contract breach, penalties for violation of applicable laws or regulations, and significant costs for remediation efforts to prevent future occurrences.

In addition, we rely on various third parties, including health plans, brokers and other third-party service providers and consumers themselves, as users of our system, for key activities to protect and promote the security of our systems and the data and information accessible within them, such as enrollment information, consumer status changes and payment. On occasion, certain individuals have failed to perform these activities. For example, authorized users have failed to administer and use the login/password appropriately, which may allow the system to be accessed by unauthorized third parties. When we become aware of such breaches or incidents, we work with our customers to remedy the issue, terminate inappropriate access as necessary, and provide additional instruction in order to avoid the reoccurrence of such problems. Although to date these breaches have

20

Table of Contents

not resulted in claims against us or in material harm to our business, failures to perform these activities might result in claims against us, which could expose us to significant expense, legal liability, and harm to our reputation, which might result in loss of business.

Our security measures, and those of our third-party service providers, may not detect or prevent all attempts to hack our systems, denial-of-service attacks, viruses, malicious software, security breaches or other attacks and similar disruptions that may jeopardize the security of information stored in or transmitted by our sites, networks and systems or that we or our third-party service providers otherwise maintain, including payment card systems which may subject us to fines or higher transaction fees or limit or terminate our access to certain payment methods. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target, we and our hosting service providers might not be able to detect or prevent these techniques or to implement adequate preventive measures until after the techniques or other attacks have already been launched. If an actual or perceived breach of our security or that of our hosting service providers occurs, the market perception of the effectiveness of our security measures could be harmed and we could lose sales and customers. In addition, our customers might authorize or enable third parties to access their information and data that is stored on our systems. Because we do not control such access, we cannot ensure the complete integrity or security of such data in our systems.

For a more detailed discussion of the risks associated with a failure by us to comply with any of the federal and state standards regarding patient privacy, identity theft prevention and detection and data security, see the risk factor below under “—Risks Related to Regulation—The healthcare and health insurance industries are heavily regulated. Our failure to comply with regulatory requirements could create liability for us, result in adverse publicity and negatively affect our business.”

Our substantial level of indebtedness could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, expose us to interest rate risk to the extent of our variable rate debt and prevent us from meeting obligations on our indebtedness.

We have a substantial amount of indebtedness. As of June 30, 2014, our total indebtedness was $54.5 million. Our substantial level of indebtedness could adversely affect our financial condition and increase the possibility that we may be unable to generate cash sufficient to pay, when due, the principal, interest or other amounts due in respect of our indebtedness. Our substantial indebtedness, combined with our other existing and any future financial obligations and contractual commitments, could have important adverse consequences. For example, it could:

21

Table of Contents

See the section titled “Liquidity and Capital Resources—Senior Credit Facility” for a description of our bank credit facility, as well as details related to prior non-compliance with financial covenants thereof and the subsequent amendment of the credit facility.

We might require additional capital to support business growth, and this capital might not be available.

We intend to continue to make investments to support our business growth and might require additional funds to respond to business challenges or opportunities, including the need to develop new products and services or enhance our existing services, enhance our operating infrastructure, and acquire complementary businesses and technologies. Accordingly, we might need to engage in equity or debt financings to secure additional funds. If we raise additional funds through new 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. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which might make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, we might not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.

Because we recognize revenue and expense relating to delivery of software, transaction fees and professional services over varying periods, downturns or upturns in sales are not immediately reflected in full in our operating results.

We recognize recurring revenue monthly over the term of our contracts and recognize the majority of our professional services revenue ratably over the contract term or the estimated expected life of the customer relationship, whichever is longer. As a result, a portion of the revenue we report each quarter is the recognition of deferred revenue from contracts we entered into during previous quarters. Consequently, a shortfall in demand for our software solutions and professional services or a decline in new or renewed contracts in any one quarter might not significantly reduce our revenue for that quarter, but could negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in new or renewed sales of our products and services is not reflected in full in our results of operations until future periods. Our revenue recognition model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, because revenue from new customers must be recognized over the applicable term of the contracts or the estimated expected life of the customer relationship period, whichever is longer. In addition, we recognize professional services expenses as incurred, which could cause professional services gross margin to be negative.

We have recorded a significant amount of goodwill, intangible assets and deferred implementation costs. We may need to record write-downs from future impairments of these assets, which could adversely affect our costs and business operations.

Our consolidated balance sheet includes significant goodwill, intangible assets and deferred implementation costs, including approximately $26.8 million in goodwill, $17.4 million in other intangible assets and $23.4 million of deferred implementation costs, together representing approximately 79% of our total assets as of June 30, 2014. The determination of related estimated useful lives and whether these assets are impaired involves significant judgments and our ability to accurately predict future cash flows related to these intangible assets may

22

Table of Contents

not be accurate. We test our goodwill for impairment each fiscal year, but we also test goodwill, other intangible assets and deferred implementation costs for impairment at any time when there is a change in circumstances that indicates that the carrying value of these assets may be impaired. Any future determination that these assets are carried at greater than their fair value could result in substantial non-cash impairment charges, which could significantly impact our reported operating results.

If we are required to collect sales and use taxes in additional jurisdictions, we might be subject to liability for additional sales and use taxes and our future sales may decrease.

We might incur significant expenses, and, as a result, lose sales, if states successfully impose broader guidelines on state sales and use taxes or successfully argue that current guidelines apply to us. We currently collect sales and use tax in a limited number of states. A successful assertion by one or more states requiring us to collect sales or other taxes on the licensing of our software or sale of our services could result in substantial tax liabilities for past transactions and otherwise harm our business. Each state has different rules and regulations governing sales and use taxes, and these rules and regulations are subject to varying interpretations that change over time. We review these rules and regulations periodically and, when we believe we are subject to sales and use taxes in a particular state, voluntarily engage with state tax authorities in order to determine how to comply with their rules and regulations. We cannot assure you that we will not be subject to sales and use taxes or related interest and penalties for past sales or use taxes in states where we currently believe no such taxes are required.

Vendors of services, like us, are typically held responsible by taxing authorities for the collection and payment of any applicable sales and similar taxes. If one or more taxing authorities determines that taxes should have, but have not, been paid with respect to our services, we might be liable for past taxes in addition to taxes going forward. Liability for past taxes might also include substantial interest and penalty charges. Our customer contracts typically provide that our customers must pay all applicable sales and similar taxes. Nevertheless, our customers might be reluctant to pay back taxes and might refuse responsibility for interest or penalties associated with those taxes. If we are required to collect and pay back taxes and the associated interest and penalties, and if our customers fail or refuse to reimburse us for all or a portion of these amounts (or if we decline to seek reimbursement from our clients), we will incur unplanned expenses that may be substantial. Moreover, imposition of such taxes on us going forward will effectively increase the cost of our software and services to our customers and might adversely affect our ability to retain existing customers or to gain new customers in the areas in which such taxes are imposed.

We might not be able to utilize a significant portion of our net operating loss or other tax credit carryforwards, which could adversely affect our future operating cash flows.

As of December 31, 2013, we had federal and state net operating loss carryforwards due to prior period losses, which if not utilized, will begin to expire in 2020. These carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our future operating cash flows.

In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, our ability to utilize net operating loss carryforwards or other tax attributes 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 might apply under state tax laws. As a result of prior equity issuances and other transactions in our stock, we have previously experienced “ownership changes” under Section 382 which limit the amount of net operating losses available to us. This offering or future issuances of our stock could cause an additional “ownership change.” Accordingly, the application of Section 382 could have a material effect on the use of our net operating loss carryforwards or other tax attributes, which could adversely affect our future operating cash flows.

As of December 31, 2013 and 2012, we have recorded a full valuation allowance against net operating loss carryforwards, because we believe it is more likely than not that some portion or all of these deferred tax assets will not be realized.

Failure to adequately expand our direct sales force will impede our growth.

We believe that our future growth will depend on the continued expansion of our direct sales force and its ability to obtain new customers and sell additional products and services to existing customers. Identifying and recruiting qualified personnel and training them in the use of our software requires significant time, expense, and attention. It can take up to six months or longer before a new sales representative is fully trained and productive. Our business may be adversely affected if our efforts to expand and train our direct sales force do not generate a corresponding increase in revenue. In particular, if we are unable to hire and develop sufficient numbers of productive direct sales personnel or if new direct sales personnel are unable to achieve desired productivity levels in a reasonable period of time, sales of our products and services will suffer and our growth will be impeded.

Our government business relies on working effectively with the prime contractors that hold the contract with the government customers and those contracts being renewed or extended, as applicable. To the extent those relationships are not positively maintained or such contracts, such as our subcontract in connection with the Centers for Medicare and Medicaid Services, or CMS, contract, are not renewed or extended, it could have a material adverse effect on our business.

In our government business to date, we have only worked as a subcontractor to prime contractors and systems integrators that contract directly with the federal government and state governments. In the scope of these relationships, we have provided specified components of the applicable government entity’s overall request, but have not assumed responsibility for the operation of the government websites. Based on our risk analysis of multiple factors, including the scope of the government entity’s request, the total potential contract value and the terms and conditions of the applicable contract, we have determined that operating in a subcontractor role has been most appropriate for our government business. It may or may not be more beneficial for us to contract directly with the government due to various factors including insurance, risk and liability issues. In order to secure government business, it is important that we identify and market our capabilities to the prime contractor community, participate on joint requests for proposals, and maintain effective working relationships throughout the term of the contract.

In many cases, payment for our products and services is dependent upon the prime contractor getting paid by the government customer. As such, we may not be paid on a timely basis or at all if the prime contractor or other subcontractors have not completed their work.

We use staff contracting firms located internationally or that source their resources from outside the United States to augment our employee base and assist in the development, distribution and delivery of our solutions. Future work with these firms might expose us to risks that could have a material adverse effect on our business.

We use staff contracting firms (both onshore and offshore) to scale up or down based on customer needs, work across various time zones to meet speed to market requirements, and lower our total cost of delivery. For over nine years, we have used staff contracting firms with employees located internationally. Associated risks include:

In addition, our customers may require us to staff projects with only employed or domestically-based staff. That requirement could increase our cost of delivery, which in turn could decrease our competiveness and lower our overall profitability.

Any future litigation against us could be costly and time-consuming to defend and could have a material adverse effect on our business, financial condition and results of operations.

We may become subject, from time to time, to legal proceedings and claims that arise in the ordinary course of business such as claims brought by our customers in connection with commercial disputes or employment claims made by our current or former employees. Litigation might result in substantial costs and may divert management’s attention and resources, which might seriously harm our business, overall financial condition, and operating results. We generally intend to defend ourselves vigorously; however, we cannot be certain of the ultimate outcomes of any claims that may arise in the future. Insurance might not cover such claims, might not provide sufficient payments to cover all the costs to resolve one or more such claims, and might not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipated costs, thereby reducing our operating results and leading analysts or potential investors to reduce their expectations of our performance, which could reduce the trading price of our stock. Additionally, certain litigation or the resolution of certain litigation may affect the availability or cost of some of our insurance coverage, which could adversely impact our results of operations and cash flows, expose us to increased risks that would be uninsured and adversely impact our ability to attract officers and directors.

We might be unable to adequately protect our intellectual property, and intellectual property claims against us could result in the loss of significant rights. Even if we are successful in enforcing our intellectual property rights, we may incur significant costs in doing so, which could have a material adverse effect on our business.

Our success depends in part upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including trademark, copyright, trade secret and other intellectual property rights, as well as customary contractual protections. Our intellectual property rights extend to our technologies and software applications. We also rely on intellectual property licensed from third parties. Our attempts to protect our intellectual property might be challenged by others or invalidated through administrative process or litigation. To the extent that our intellectual property and other proprietary rights are not adequately protected, third parties might gain access to our proprietary information, develop and market products or services similar to ours, or use trademarks similar to ours, each of which could materially harm our business.

From time to time, third parties have alleged, and may allege in the future that we have violated their intellectual property rights. If we are forced to defend ourselves against intellectual property infringement claims, regardless of the merit or ultimate result of such claims, we may face costly litigation, diversion of technical and management personnel, limitations on our ability to market or provide our products and services. As a result of any such dispute, we may have to:

Table of Contents

Moreover, if we are unable to implement one or more of the remedial actions described above, we may be prevented from continuing to offer, and our customers may be prevented from continuing to use, any of our affected products or services.

The use of open source software in our products and solutions may expose us to additional risks and harm our intellectual property rights.

Some of our products and solutions use or incorporate software that is subject to one or more open source licenses. Open source software is typically freely accessible, usable, and modifiable. Certain open source software licenses require a user who intends to distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’s software. In addition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others on potentially unfavorable terms or at no cost.

The terms of many open source licenses to which we are subject have not been interpreted by United States or foreign courts. Accordingly, there is a risk that those licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to commercialize our solutions. In that event, we could be required to seek licenses from third parties in order to continue offering our products or solutions, to re-develop our products or solutions, to discontinue sales of our products or solutions, or to release our proprietary software code under the terms of an open source license, any of which could harm our business. Further, given the nature of open source software, it may be more likely that third parties might assert copyright and other intellectual property infringement claims against us based on our use of these open source software programs.

While we monitor the use of all open source software in our products, solutions, processes, and technology and try to ensure that no open source software is used in such a way as to require us to disclose the source code to the related product or solution when we do not wish to do so, it is possible that such use may have inadvertently occurred in deploying our proprietary solutions. In addition, if a third-party software provider has incorporated certain types of open source software into software we license from such third party for our products and solutions without our knowledge, we could, under certain circumstances, be required to disclose the source code to our products and solutions. This could harm our intellectual property position and our business, results of operations, and financial condition.

Our confidentiality arrangements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information, and any such disclosure could have a material adverse effect on our business.

We have devoted substantial resources to the development of our technology, business operations and business plans. In order to protect our trade secrets and proprietary information, we rely in significant part on confidentiality arrangements with our employees, independent contractors, advisers and customers. These arrangements may not be effective to prevent disclosure of confidential information, including trade secrets, and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we would not be able to assert trade secret rights against such parties. The loss of trade secret protection could make it easier for third parties to compete with our products and services by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret and other intellectual property laws may compromise our ability to enforce our trade secret and intellectual property rights. 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 have a material adverse effect on our business.

If we acquire companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute stockholder value, and adversely affect our operating results and the value of our common stock.

As part of our business strategy, we might acquire, enter into joint ventures with, or make investments in complementary companies, services, and technologies in the future. For example, in 2013, we acquired DestinationRx, Inc., or DRX. We spent considerable time, effort, and money acquiring this company and integrating it into our business. Acquisitions and investments involve numerous risks, including:

If we fail to properly evaluate acquisitions or investments, we might not achieve the anticipated benefits of any such acquisitions, we might incur costs in excess of what we anticipate, and management resources and attention might be diverted from other necessary or valuable activities, which would have a material adverse effect on our business and results of operations.

Consolidation in the health insurance industry in which our customers operate could cause us to lose customers or could reduce the volume of services purchased by consolidated customers following an acquisition or merger, which could have a material adverse effect on our business.

Consolidation in the health insurance industry has accelerated in recent years, and this trend could continue. We may lose customers due to industry consolidation, and we may not be able to expand sales of our solutions and services to new customers to replace lost customers. In addition, new companies or organizations that result from such consolidation may decide that our solutions are no longer needed because of their own internal processes or the use of alternative solutions. As these entities consolidate, competition to provide solutions and services to industry participants will become more intense and the importance of establishing relationships with large industry participants will become greater. These industry participants may try to use their market power to negotiate price reductions for our solutions. Also, if consolidation of larger current customers occurs, the combined company may represent a larger percentage of business for us and, as a result, we are likely to rely more significantly on the combined company’s revenue to continue to achieve growth. As a result, industry consolidation or consolidation among current customers or potential customers could adversely affect our business.

We depend on our senior management team and other key employees, and the loss of one or more key personnel or an inability to attract hire, integrate and retain highly skilled personnel could adversely affect our business.

Our success depends largely upon the continued services of key personnel. We also rely on our leadership team in the areas of research and development, marketing, services, and general and administrative functions, and on mission-critical individual contributors in research and development. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. The loss of one or more of our executive officers or other key employees could have a serious adverse effect on our business. The replacement of one or more of our executive officers or other key employees would involve significant time and expense and may significantly delay or prevent the achievement of our business objectives.

27

Table of Contents

To continue to execute our growth strategy, we also must identify, hire and retain highly skilled personnel. Competition is intense for engineers with high levels of experience in designing and developing software and Internet-related services. We might not be successful in maintaining our unique culture and continuing to attract and retain qualified personnel. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled personnel with appropriate qualifications. The pool of qualified personnel is limited overall and specifically in the geographic regions in which our principal offices are located. Failure to identify, hire and retain necessary key personnel could have a material adverse effect on our business, financial condition and results of operations.

Consumers of health insurance are increasingly relying on mobile devices as part of their decision-making process. If we are unsuccessful in expanding the capabilities of our shopping tools for mobile platforms, it could adversely affect our business.

We believe that consumers of health insurance are increasingly relying on mobile devices, such as smartphones and tablets, in connection with their health insurance purchasing decisions. Traditionally, our solutions have been designed for desktop platforms, and we must develop new capabilities to deliver compelling user experiences via mobile devices. To deliver high quality mobile offerings, it is important that our solutions integrate with a wide range of other mobile technologies, systems, networks and standards that we do not control. We may not be successful in developing products that operate effectively with these technologies, systems, networks or standards. Further, our success on mobile platforms will be dependent on our interoperability with popular mobile operating systems that we do not control, such as Android, iOS and Windows Mobile, and any change in such systems that degrade our functionality or give preferential treatment to competitive products could adversely affect usage of our solutions through mobile devices. If we fail to achieve success with our mobile offerings, our ability to deliver compelling user experiences to consumers as they increasingly rely on mobile devices in connection with their health insurance purchasing decisions will be constrained and our business could be adversely affected.

If we cannot maintain our corporate culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success, which could have a material adverse effect on our business.

We believe that a critical component to our success has been our corporate culture. We have invested substantial time and resources in building our team. As we continue to grow, we may find it difficult to maintain the innovation, teamwork, passion and focus on execution that we believe are important aspects of our corporate culture. Any failure to preserve our culture could negatively affect our future success, including our ability to retain and recruit personnel and to effectively focus on and pursue our corporate objectives.

Failure by our customers to obtain proper permissions and waivers might result in claims against us or may limit or prevent our use of data, which could have a material adverse effect on our business.

We require our customers to provide necessary notices and to obtain necessary permissions and waivers for use and disclosure of information on our platform, and we require contractual assurances from them that they have done so and will do so. If, however, despite these requirements and contractual obligations, our customers do not obtain necessary permissions and waivers, then our use and disclosure of information that we receive from them or on their behalf might be limited or prohibited by state or federal privacy laws or other laws. This could impair our functions, processes and databases that reflect, contain, or are based upon such data and might prevent use of such data. In addition, this could interfere with, or prevent creation or use of, rules, analyses, or other data-driven activities that benefit us and our business. Moreover, we might be subject to claims or liability for use or disclosure of information by reason of lack of valid notices, agreements, permissions or waivers. These claims or liabilities could subject us to unexpected costs and adversely affect our operating results.

Risks Related to Regulation

The healthcare and health insurance industries are heavily regulated. Our failure to comply with regulatory requirements could create liability for us, result in adverse publicity and negatively affect our business.

The healthcare and health insurance industries are highly regulated and are subject to changing political, legislative, regulatory, and other influences. Existing and new laws and regulations could create unexpected liabilities for us, cause us to incur additional costs and restrict our operations. These laws and regulations are complex and their application to specific services and relationships are not clear. In particular, many existing laws and regulations affecting healthcare and health insurance and related benefits or products when enacted, did not anticipate the services that we provide, and these laws and regulations might be applied to our services in ways that we do not anticipate. Our failure to accurately anticipate the application of these laws and regulations, or our failure to comply, could require us to change our operations or cease using certain datasets, create liability for us, result in adverse publicity, and negatively affect our business. Some of the risks we face from the regulation of healthcare and health insurance are as follows:

29

Table of Contents

Violations of the Privacy Standards and Security Standards might result in civil and criminal penalties, and ARRA increased the penalties for HIPAA violations and strengthened the enforcement provisions of HIPAA. For example, ARRA authorizes state attorneys general to bring civil actions seeking either injunctions or damages in response to violations of Privacy Standards and Security Standards that threaten the privacy of state residents. Additionally, some health plans interpret HIPAA requirements differently than we do, and as our customers are the Covered Entity under HIPAA we may be required to comply with their interpretations.

We might not be able to adequately address the business risks created by HIPAA implementation. Furthermore, we are unable to predict what changes to HIPAA or other laws or regulations might be made in the future or how those changes could affect our business or the costs of compliance.

In addition to the Privacy Standards and Security Standards, most states have enacted patient confidentiality laws that protect against the disclosure of confidential medical and/or health information, and many states have adopted or are considering further legislation in this area, including privacy safeguards, security standards, and data security breach notification requirements. Such state laws, if more stringent than HIPAA requirements, are not preempted by the federal requirements and we are required to comply with them. Additionally, other laws or standards may apply to our operations, including requirements related to handling certain financial information, federal tax information, or FTI, and payment card association operating rules with respect to credit card data.

Failure by us to comply with any state standards regarding patient privacy may subject us to penalties, including civil monetary penalties and, in some circumstances, criminal penalties. Such failure may injure our reputation and adversely affect our ability to retain customers and attract new customers.

The growth in the Medicare plan market is important to the overall growth rate of our business. The marketing and sale of Medicare plans are subject to numerous, complex and frequently changing laws and regulations, and the impact of changes in laws related to Medicare or any failure to comply with them could harm our business, results of operations and financial condition.

The number of people eligible for Medicare is one of the most significant drivers in the growth of Medicare plans. Any changes in the eligibility requirements for Medicare such as raising the age of eligibility would decrease the available pool of recipients and lower our growth expectations.

The marketing and sale of Medicare plans are subject to numerous laws, regulations and guidelines at both the Federal and state level. The marketing and sale of Medicare Advantage and Medicare Part D prescription drug plans are principally regulated by CMS, which is a division of the United States Department of Health and Human Services, and the marketing and sale of Medicare supplement plans is principally regulated on a state- by- state basis by state departments of insurance. The laws and regulations applicable to the marketing and sale of Medicare plans lack clarity, are numerous and complex, were not drafted to contemplate health insurance exchanges, and change frequently, particularly with respect to regulations and guidance issued by CMS for Medicare Advantage and Medicare Part D prescription drug plans and by the various state departments of insurance for Medicare supplement plans.

As a result of these laws, regulations and guidelines, we have altered, and will need to continue to alter, our business operations and procedures, including without limitation, to comply with these changing requirements. Though our health plan customers remain responsible to comply with CMS requirements, we operate as an FDR, in support of our customers. Changes to the laws, regulations and guidelines relating to Medicare plans, the scope of their application to our business, their interpretation by regulators or our health plan customers, or the manner

31

Table of Contents

in which they are enforced could be incompatible with our business model. As a result, our business could be slowed or we could be prevented from operating portions of our business altogether, either of which would materially harm our results of operations and financial condition, particularly if this occurred during the Medicare annual enrollment period, which is when the vast majority of Medicare plans are sold.

Health plans may adjust their commission rates to comply with regulatory guidelines, such as those published by CMS with respect to the marketing of Medicare Advantage and Medicare Part D prescription drug plans. If these contractual changes result in reduced commissions, our revenue may decline. Because insurance rates may vary between health plans, plans and enrollment dates, changes in enrollment mix may impact our commission revenue. Future changes in health plan pricing practices could harm our business, results of operations and financial condition.

In March 2010, the Federal government enacted significant reforms to healthcare legislation through the PPACA and the HCERA, which we refer to collectively as Healthcare Reform. In addition, one of the elements of the recently passed Budget Control Act of 2011 is the creation of a joint select committee on deficit reduction to develop recommendations, including changes to entitlement programs such as Medicare, to reduce the national debt by at least $1.5 trillion over 10 years. In connection with the United Sates Congress’s failure to agree on a proposal to lower the national deficit, the Budget Control Act mandates automatic cuts to domestic and defense spending, including a significant reduction in Medicare spending. The impact that Healthcare Reform and the Budget Control Act will have on the market for Medicare plans could change the demand for Medicare plans, the way these plans are delivered, or the commissions that health plans pay to us in connection with their sale or otherwise adversely impact us.

In the event that these laws and regulations or changes in these laws and regulations, or other laws and regulations that impact the marketing and sale of Medicare plans, adversely impact our ability or our customers’ ability to market any type of Medicare plan on an exchange platform or the commissions that we receive for selling these plans, our business, results of operations and financial condition would be harmed.

Additional regulatory requirements placed on our software, services, and content could impose increased costs on us, delay or prevent our introduction of new service types, and impair the function or value of our existing service types.

Our products and services are and are likely to continue to be subject to increasing regulatory requirements in a number of ways. As these requirements proliferate, we must change or adapt our products and services to comply. Changing regulatory requirements might render our services obsolete or might prevent us from pursuing our business objective or developing new services. This might in turn impose additional costs upon us to comply or to further develop our products and services. It might also make introduction of new product or service types more costly or more time-consuming than we currently anticipate. It might even prevent introduction by us of new products or services or cause the continuation of our existing products or services to become unprofitable or impossible.

Potential government subsidy of services similar to ours, or creation of a single-payer system, might reduce customer demand.

Recently, entities including brokers and United States federal and state governments have offered to subsidize adoption of online benefits platforms or clearinghouses. In addition, prior proposals regarding healthcare reform have included the concept of creation of a single payer for health insurance. This kind of consolidation of critical benefits activity could negatively impact the demand for our services.

Risk Related to this Offering and Ownership of our Common Stock

An active, liquid, and orderly market for our common stock may not develop.

Prior to this offering, there was no market for shares of our common stock. An active trading market for our common stock might never develop or be sustained, which could depress the market price of our common stock and affect your ability to sell our shares. The initial public offering price will be determined through negotiations between us and the representatives of the underwriters and might bear no relationship to the price at which our common stock will trade following the completion of this offering. The trading price of our common stock following this offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include:

In addition, the stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. These fluctuations might be even more pronounced in the trading market for our stock shortly following this offering. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. This litigation, if instituted against us, could result in substantial costs, divert our management’s attention and resources, and harm our business, operating results, and financial condition.

Our management team has no prior experience managing a public company, and regulatory compliance may divert its attention from day-to-day management of our business, which could have a material adverse effect on our business.

The individuals who now constitute our management team have no prior experience managing a publicly-traded company or complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our continued transition to a public company that will be subject to significant regulatory oversight and reporting obligations under the federal securities laws and the regulations imposed by                     . In particular, these new obligations will require substantial attention from our senior management and could divert their attention away from the day-to-day management of our business, which could materially and adversely impact our business operations.

We have broad discretion in the use of the net proceeds from this offering and might not use them effectively.

We cannot specify with certainty the particular uses of the net proceeds we will receive from this offering. Our management will have broad discretion in the application of the net proceeds, including for any of the purposes described in “Use of Proceeds.” Accordingly, you will have to rely on the judgment of our management

33

Table of Contents

with respect to the use of the proceeds, with only limited information concerning management’s specific intentions. Our management might spend a portion or all of the net proceeds from this offering in ways that our stockholders do not desire or that might not yield a favorable return. The failure by our management to apply these funds effectively could harm our business. Pending their use, we might invest the net proceeds from this offering in a manner that does not produce income or that loses value.

A limited number of stockholders will have the ability to influence the outcome of director elections and other matters requiring stockholder approval.

After this offering, our directors, executive officers, and their affiliated entities will beneficially own more than     % of our outstanding common stock (assuming no exercise of the underwriters’ option to purchase additional shares and no exercise of outstanding options after June 30, 2014). In particular, after this offering,             , collectively will beneficially own approximately     % (assuming no exercise of the underwriters’ option to purchase additional shares and no exercise of outstanding options after June 30, 2014). These stockholders, if they act together, could exert substantial influence over matters requiring approval by our stockholders, including the amendment of our amended and restated certificate of incorporation and amended and restated bylaws, and the approval of mergers or other business combination transactions.

This concentration of ownership might discourage, delay, or prevent a change in control of our company, which could deprive our stockholders of an opportunity to receive a premium for their stock as part of a sale of our company and might reduce our stock price. These actions may be taken even if they are opposed by other stockholders, including those who purchase shares in this offering.

Future sales of shares of our common stock by existing stockholders could depress the market value of our common stock.

Upon completion of this offering, there will be              shares of our common stock outstanding. The              shares being sold in this offering will be freely tradable immediately after this offering (except for shares purchased by affiliates) and of the              shares outstanding on a pro forma as adjusted basis as of              (assuming no exercise of outstanding options after June 30, 2014),              shares may be sold upon expiration of lock-up agreements 180 days after the date of this offering (subject in some cases to volume limitations). In addition, as of             , there were outstanding options to purchase              shares of our common stock that, if exercised, will result in these additional shares becoming available for sale upon expiration of the lock-up agreements. A large portion of these shares and options are held by a small number of persons and investment funds. Sales by these stockholders or option holders of a substantial number of shares after this offering could significantly reduce the market price of our common stock. Moreover, after this offering, some holders of shares of common stock will have rights, subject to some conditions, to require us to file registration statements covering the shares they currently hold, or to include these shares in registration statements that we might file for ourselves or other stockholders.

We also intend to register all common stock that we may issue under our equity incentive plans. Effective upon the completion of this offering, an aggregate of              shares of our common stock will be reserved for future issuance under these plans (assuming no exercise of outstanding options after June 30, 2014). Once we register these shares, which we plan to do shortly after the completion of this offering, they can be freely sold in the public market upon issuance, subject to the lock-up agreements referred to above. If a large number of these shares are sold in the public market, the sales could reduce the trading price of our common stock. See “Shares Eligible for Future Sale” for a more detailed description of sales that may occur in the future.

You will experience immediate and substantial dilution.

The initial public offering price will be substantially higher than the net tangible book value of each outstanding share of common stock immediately after this offering. If you purchase common stock in this

34

Table of Contents

offering, you will suffer immediate and substantial dilution. At an assumed initial public offering price of $         with net proceeds to the Company of $         million, after deducting estimated underwriting discounts and commissions and estimated offering expenses, investors who purchase shares in this offering from us will have contributed approximately     % of the total amount of funding we have received to date, but the shares purchased from us in this offering will represent only approximately     % of the total voting rights. The dilution will be $         per share in the net tangible book value of the common stock from the assumed initial public offering price. In addition, if outstanding options to purchase shares of our common stock are exercised, there could be further dilution. For more information refer to “Dilution.”

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

The trading market for our common stock will, to some extent, depend on the research and reports that securities or industry analysts publish about us and our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our common stock or change their opinion of our common stock, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

We will incur significant increased expenses and administrative burdens as a public company, which could have a material adverse effect on our operations and financial results.

We will face increased legal, accounting, administrative and other costs and expenses as a public company that we do not incur as a private company. The Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the Securities and Exchange Commission, or SEC, the Public Company Accounting Oversight Board and the             , impose additional reporting and other obligations on public companies. We expect that compliance with public company requirements will increase our costs and make some activities more time-consuming. A number of those requirements will require us to carry out activities we have not done previously. For example, we will create new board committees and adopt new internal controls and disclosure controls and procedures. In addition, we will incur additional expenses associated with our SEC reporting requirements. Furthermore, if we identify any issues in complying with those requirements (for example, if we or our auditors identify a material weakness or significant deficiency in our internal control over financial reporting), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect us, our reputation or investor perceptions of us. We also expect that it will be more expensive to obtain director and officer liability insurance. Risks associated with our status as a public company may make it more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. We expect that the additional reporting and other obligations imposed on us by these rules and regulations will increase our legal and financial compliance costs and the costs of our related legal, accounting and administrative activities by approximately $         million per year. These increased costs will require us to divert a significant amount of money that we could otherwise use to expand our business and achieve our strategic objectives. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase our costs.

We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We have never declared or paid any cash dividends on our common stock and do not currently intend to do so for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future, and the success of an investment in shares of our common stock will depend upon future appreciation in its value, if any. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders purchased their shares.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and Delaware law might discourage, delay, or prevent a change in control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws and Delaware law might discourage, delay, or prevent a merger, acquisition, or other change in control that stockholders consider favorable, including transactions in which you might otherwise receive a premium for your shares of our common stock. These provisions might also prevent or frustrate attempts by our stockholders to replace or remove our management. These provisions include:

Our board of directors has the ability to designate the terms of and issue new series of preferred stock without stockholder approval. In addition, Section 203 of the Delaware General Corporation Law prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years has owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

The existence of the foregoing provisions and anti-takeover measures could limit the price that investors are willing to pay in the future for shares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that you could receive a premium for your common stock in an acquisition.

We currently qualify as an emerging growth company under the JOBS Act and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

The JOBS Act permits “emerging growth companies” like us to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies.

In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as we are an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.

For as long as we continue to be an emerging growth company, we intend to take advantage of certain other exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved, and exemptions from the requirements of auditor attestation reports on the effectiveness of our internal control over financial reporting. We have elected to take advantage of the extended transition period for complying with new or revised

36

Table of Contents

accounting standards under Section 102(B)(1), which will allow us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of this offering, (b) in which we have total annual gross revenue of at least $1.0 billion, or (c) in which we become a large accelerated filer, which means that we have been public for at least 12 months, have filed at least one annual report and the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last day of our then most recently completed second fiscal quarter, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.
