RISK FACTORS

         Investing in our common stock involves a high degree of risk. You should carefully consider the following risks and all other information contained in this prospectus, including our consolidated financial statements and the related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. If any of the following risks materialize, our business, financial condition and results of operations could be materially adversely affected. In that case, the trading price of our common stock could decline, and you may lose some or all of your investment.

Risks Related to Our Business and Industry

The market for our software is new and unproven and may not grow.

        We believe our future success will depend in large part on the growth, if any, in the market for software that provides operational intelligence, particularly software designed to collect and index machine data. We market our software as a targeted solution for specific use cases and as an enterprise solution for machine data. In order to grow our business, we intend to expand the functionality of our product to increase its acceptance and use by the broader market. It is difficult to predict customer adoption and renewal rates, customer demand for our software, the size and growth rate of this market, the entry of competitive products or the success of existing competitive products. Any expansion in our market depends on a number of factors, including the cost, performance and perceived value associated with such software. If the market for our software does not achieve widespread adoption or there is a reduction in demand for software in our market caused by a lack of customer acceptance, technological challenges, lack of accessible machine data, competing technologies and products, decreases in corporate spending, weakening economic conditions, or otherwise, it could result in reduced customer orders, early terminations, reduced renewal rates or decreased revenues, any of which would adversely affect our business operations and financial results. You should consider our business and prospects in light of the risks and difficulties we encounter in this new and unproven market.

We have a short operating history, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful.

        We have a short operating history, which limits our ability to forecast our future operating results and subjects us to a number of uncertainties, including our ability to plan for and model future growth. We have encountered and will continue to encounter risks and uncertainties frequently experienced by growing companies in developing industries. If our assumptions regarding these uncertainties, which we use to plan our business, are incorrect or change in reaction to changes in our markets, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations and our business could suffer. Moreover, although we have experienced rapid growth historically, we may not continue to grow as rapidly in the future. Any success that we may experience in the future will depend in large part on our ability to, among other things:

maintain and expand our customer base and the ways in which our customers use our software;

increase revenues from existing customers through increased or broader use of our software within their organizations;

improve the performance and capabilities of our software through research and development;

continue to develop our cloud-based service, Splunk Storm;

successfully expand our business domestically and internationally;

successfully compete with other companies, open source initiatives and custom development efforts that are currently in, or may in the future enter, the markets for our software;

11

Table of Contents

continue to invest in our application development platform to foster an ecosystem of developers and users to expand the use cases of our software;

generate leads and convert users of the trial version of our software to paying customers;

prevent users from circumventing the terms of their software licenses;

maintain and enhance our website infrastructure to minimize interruptions or slower than expected download times when accessing our software from our website;

process, store and use our customers' data in compliance with applicable governmental regulations and other legal obligations related to data privacy; and

hire, integrate and retain world class talent.

        If we fail to address the risks and difficulties we face including those described elsewhere in this "Risk Factors" section, our business will be adversely affected and our operating results will suffer.

Our future operating results may fluctuate significantly, and our recent operating results may not be a good indication of our future performance.

        Our revenues and operating results could vary significantly from period to period as a result of various factors, many of which are outside of our control. For example, we typically enter into perpetual license agreements, whereby we generally recognize the license fee portion of the arrangement upfront, assuming all revenue recognition criteria are satisfied. Our customers also have the choice of entering into term licenses for our software, whereby the license fee is recognized ratably over the license term. At the beginning of each quarter, we do not know the ratio between perpetual licenses and term licenses that we will enter into during the quarter. As a result, our operating results could be significantly impacted by unexpected shifts in the ratio between perpetual licenses and term licenses. In addition, the size of our licenses varies greatly, and a single, large perpetual license in a given period could distort our operating results. 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. In particular, since the beginning of fiscal 2011, more than 70% of the revenues we recognize each quarter has been attributable to sales made in that same quarter with the balance of the revenues being attributable to sales made in prior quarters in which the related revenues were not recognized upfront. As a result, our ability to forecast revenues on a quarterly or longer term basis is extremely limited. We base our current and future expense levels on our operating plans and sales forecasts, and our operating costs are expected to be 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 our financial results for that quarter.

        In addition to other risk factors described elsewhere in this "Risk Factors" section, factors that may cause our operating results to fluctuate from quarter to quarter include:

the timing of our sales during the quarter, particularly because a large portion of our sales occur toward the end of the quarter, and the loss or delay of a few large contracts may have a significant adverse impact on our operating results;

the mix of revenues attributable to larger transactions as opposed to smaller transactions and the impact that a change in mix may have on the overall average selling price of our software;

the mix of revenues attributable to perpetual and term licenses, maintenance and professional services and training, which may impact our gross margins and operating income;

the renewal and usage rates of our customers;

12

Table of Contents

changes in the competitive dynamics of our market;

changes in customers' budgets and in the timing of their purchasing decisions;

customers delaying purchasing decisions in anticipation of new software or software enhancements by us or our competitors;

customer acceptance of and willingness to pay for new versions of our software or new solutions for specific product and end markets;

our ability to control costs, including our operating expenses;

the timing of satisfying revenue recognition criteria;

our ability to qualify and compete for government contracts;

the collectibility of receivables from customers and resellers, which may be hindered or delayed if these customers or resellers experience financial distress; and

general economic conditions, both domestically and internationally, as well as economic conditions specifically affecting industries in which our customers participate.

        Many of these factors are outside our control, and the variability and unpredictability of such factors could result in our failing to meet or exceed our financial expectations for a given period. We believe that quarter-to-quarter comparisons of our revenues, operating results and cash flows may not necessarily be indicative of our future performance.

If we fail to effectively manage our growth, our business and operating results could be adversely affected.

        Although our business has experienced significant growth, we cannot provide any assurance that our business will continue to grow at the same rate or at all. We have experienced and may continue to experience rapid growth in our headcount and operations, which has placed and will continue to place significant demands on our management and our operational and financial infrastructure. As of October 31, 2011, nearly half of our employees had been with us for less than one year. As we continue to grow, we must effectively integrate, develop and motivate a large number of new employees, while maintaining the effectiveness of our business execution and the beneficial aspects of our corporate culture. In particular, we intend to continue to make directed and substantial investments to expand our research and development, sales and marketing, and general and administrative organizations, as well as our international operations.

        To effectively manage growth, we must continue to improve our operational, financial and management controls, and our reporting systems and procedures by, among other things:

improving our key business applications, processes and IT infrastructure to support our business needs;

enhancing information and communication systems to ensure that our employees and offices around the world are well-coordinated and can effectively communicate with each other and our growing base of customers;

enhancing our internal controls to ensure timely and accurate reporting of all of our operations and financial results; and

appropriately documenting our IT systems and our business processes.

        These systems enhancements and improvements will require significant capital expenditures and allocation of valuable management and employee resources. If we fail to implement these improvements effectively, our ability to manage our expected growth, ensure uninterrupted operation of key business systems and comply with the rules and regulations that are applicable to public reporting companies will be

13

Table of Contents

impaired. Additionally, if we do not effectively manage the growth of our business and operations, the quality of our software could suffer, which could negatively affect our brand, operating results and overall business.

We have a history of losses, and we may not be profitable in the future.

        We have incurred net losses in each year since our inception, including net losses of $14.8 million in fiscal 2009, $7.5 million in fiscal 2010, $3.8 million in fiscal 2011 and $9.7 million in the nine months ended October 31, 2011. As a result, we had an accumulated deficit of $52.7 million at October 31, 2011. Because the market for our software is rapidly evolving and has not yet reached widespread adoption, it is difficult for us to predict our operating results. We expect our operating expenses to increase over the next several years as we hire additional personnel, particularly in sales and marketing, expand and improve the effectiveness of our distribution channels, and continue to develop features and applications, or apps, for our software. In addition, as we grow and as we become a newly public company, we will incur additional significant legal, accounting and other expenses that we did not incur as a private company. If our revenues do not increase to offset these increases in our operating expenses, we may not be profitable in future periods. Our historical revenue growth has been inconsistent and should not be considered indicative of our future performance. Further, in future periods, our revenue growth could slow or our revenues could decline for a number of reasons, including slowing demand for our software, increasing competition, a decrease in the growth of our overall market, or our failure, for any reason, to continue to capitalize on growth opportunities. Any failure by us to sustain or increase profitability on a consistent basis, could cause the value of our common stock to materially decline.

Because we derive substantially all of our revenues and cash flows from one software product, failure of this product to satisfy customer demands or to achieve increased market acceptance would adversely affect our business, results of operations, financial condition and growth prospects.

        We derive and expect to continue to derive substantially all of our revenues and cash flows from Splunk Enterprise. As such, the market acceptance of our software is critical to our continued success. Demand for our software is affected by a number of factors beyond our control, including continued market acceptance of our software by referenceable accounts for existing and new use cases, the timing of development and release of new products by our competitors, technological change, and growth or contraction in our market. In addition, users of software that provides operational intelligence may seek a cloud-based service and, to date, we have not offered a cloud-based service on a commercial basis. We expect the proliferation of machine data to lead to an increase in the data analysis demands of our customers, and our software may not be able to scale and perform to meet those demands. If we are unable to continue to meet customer demands or to achieve more widespread market acceptance of our software, our business, results of operations, financial condition and growth prospects will be materially and adversely affected.

We face intense competition in our markets, and we may be unable to compete effectively for sales opportunities.

        Although our product targets the new and emerging market for software that provides operational intelligence, we compete against a variety of large software vendors and smaller specialized companies, open source initiatives and custom development efforts, which provide solutions in the specific markets we address. Our principal competitors include:

IT departments of potential customers which have undertaken custom software development efforts to analyze and manage their machine data;

security and systems management vendors, including BMC Software, CA, Compuware, HP, IBM, Intel, Microsoft and Quest Software;

14

Table of Contents

web analytics vendors, including Adobe Systems, Google, IBM and Webtrends;

business intelligence vendors, including EMC, IBM, Oracle and SAP;

companies targeting the big data market by commercializing open source software, such as Hadoop; and

small specialized vendors, which provide complementary solutions in enterprise data analytics, data warehousing and big data technologies that may compete with our software.

        The principal competitive factors in our markets include product features, performance and support, product scalability and flexibility, ease of deployment and use, total cost of ownership and time to value. Some of our actual and potential competitors have advantages over us, such as longer operating histories, significantly greater financial, technical, marketing or other resources, stronger brand and business user recognition, larger intellectual property portfolios and broader global distribution and presence. Further, competitors may be able to offer products or functionality similar to ours at a more attractive price than we can by integrating or bundling their software products with their other product offerings. In addition, our industry is evolving rapidly and is becoming increasingly competitive. Larger and more established companies may focus on operational intelligence and could directly compete with us. For example, companies may commercialize open source software, such as Hadoop, in a manner that competes with our product or causes potential customers to believe that such product and our software perform the same function. If companies move a greater proportion of their data and computational needs to the cloud, new competitors may emerge which offer services comparable to ours or that are better suited for cloud-based data, and the demand for our product may decrease. Smaller companies could also launch new products and services that we do not offer and that could gain market acceptance quickly.

        In recent years, there have been significant acquisitions and consolidation by and among our actual and potential competitors. We anticipate this trend of consolidation will continue, which will present heightened competitive challenges to our business. In particular, consolidation in our industry increases the likelihood of our competitors offering bundled or integrated products, and we believe that it may increase the competitive pressures we face with respect to our software. If we are unable to differentiate our product from the integrated or bundled products of our competitors, such as by offering enhanced functionality, performance or value, we may see decreased demand for those solutions, which would adversely affect our business, results of operations, financial condition and cash flows. 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 their willingness to use software solutions 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 regardless of the performance and features of our software. We believe that in order to remain competitive at the large enterprise level, we will need to develop and expand relationships with resellers and large system integrators that provide a broad range of products and services. If we are unable to compete effectively, our business, results of operations, financial condition and cash flows could be materially and adversely affected.

If customers do not expand their use of our software beyond the current predominant use cases, our ability to grow our business and operating results may be adversely affected.

        Most of our customers currently use our software to support application management, IT operations, security and compliance functions. Our ability to grow our business depends in part on our ability to persuade current and future customers to expand their use of our software to additional use cases, such as facilities management, supply chain management, business analytics and customer usage analytics. If we fail to achieve market acceptance of our software for these applications, or if a competitor establishes a more widely adopted solution for these applications, our ability to grow our business and operating results will be adversely affected. In addition, as the amount of data indexed by our software for a given customer grows, that customer must agree to higher license fees for our software or limit the amount of data indexed

15

Table of Contents

in order to stay within the limits of its existing license. If their fees grow significantly, customers may react adversely to this pricing model, particularly if they perceive that the value of our software has become eclipsed by such fees or otherwise. If customers react adversely to our pricing model, our ability to grow our business and operating results could be adversely affected.

If we do not effectively expand and train our sales force, we may be unable to add new customers or increase sales to our existing customers and our business will be adversely affected.

        We continue to be substantially dependent on our sales force to obtain new customers and to drive additional use cases among our existing customers. We believe that there is significant competition for sales personnel with the skills and technical knowledge that we require. Our ability to achieve significant revenue growth will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel to support our growth. New hires require significant training and may take significant time before they achieve full productivity. Our recent hires and planned hires may not become productive as quickly as we expect, and we may be unable to hire or retain sufficient numbers of qualified individuals in the markets where we do business or plan to do business. In addition, as we continue to grow rapidly, a large percentage of our sales force is new to the company and our product. If we are unable to hire and train sufficient numbers of effective sales personnel, or the sales personnel are not successful in obtaining new customers or increasing sales to our existing customer base, our business will be adversely affected.

Our sales cycle is long and unpredictable, particularly with respect to large customers, and our sales efforts require considerable time and expense.

        Our operating results may fluctuate, in part, because of the resource intensive nature of our sales efforts, the length and variability of the sales cycle of our software offerings and the short-term difficulty in adjusting our operating expenses. Our operating results depend in part on sales to large customers and conversions of users that have downloaded the trial version of our software into paying customers. The length of our sales cycle, from initial evaluation to delivery of and payment for the software, varies substantially from customer to customer. Our sales cycle can extend to more than a year for large customers. It is difficult to predict exactly when, or even if, we will make a sale with a potential customer or if a user that has downloaded the trial version of our software will upgrade to the paid version of our software. As a result, large individual sales have, in some cases, occurred in quarters subsequent to those we anticipated, or have not occurred at all. The loss or delay of one or more large transactions in a quarter could impact our operating results for that quarter and any future quarters for which revenue from that transaction is delayed. As a result of these factors, it is difficult for us to forecast our revenues accurately in any quarter. Because a substantial portion of our expenses are relatively fixed in the short-term, our operating results will suffer if revenues fall below our expectations in a particular quarter, which could cause the price of our common stock to decline.

Our business and growth depend substantially on customers renewing their maintenance agreements with us. Any decline in our customer renewals could adversely affect our future operating results.

        While most of our software is sold under perpetual license agreements, all of our maintenance and support agreements are sold on a term basis. In addition, we also enter into term license agreements for our software. In order for us to improve our operating results, it is important that our existing customers renew their term licenses, if applicable, and maintenance and support agreements when the initial contract term expires. Our customers have no obligation to renew their term licenses or maintenance and support contracts with us after the initial terms have expired. Our customers' renewal rates may decline or fluctuate as a result of a number of factors, including their satisfaction or dissatisfaction with our software, our pricing, the effects of economic conditions or reductions in our customers' spending levels. If our

16

Table of Contents

customers do not renew their agreements with us or renew on terms less favorable to us, our revenues may decline.

Incorrect or improper implementation or use of our software could result in customer dissatisfaction and negatively affect our business, results of operations, financial condition and growth prospects.

        Our software is deployed in a wide variety of technology environments. Increasingly, our software has been deployed in large scale, complex technology environments, and we believe our future success will depend on our ability to increase sales of our software for use in such deployments. We often must assist our customers in achieving successful implementations for large, complex deployments. If we or our customers are unable to implement our software successfully, or unable to do so in a timely manner, customer perceptions of our company may be impaired, our reputation and brand may suffer, and customers may choose not to increase their use of our software. In addition, our software imposes server load and index storage requirements for implementation. If our customers do not have the server load capacity or the storage capacity required, they may not be able to effectively implement and use our software and, therefore, may not choose to increase their use of our software.

        Our customers and third-party partners may need training in the proper use of and the variety of benefits that can be derived from our software to maximize its potential. If our software is not implemented or used correctly or as intended, inadequate performance may result. Because our customers rely on our software and maintenance support to manage a wide range of operations, the incorrect or improper implementation or use of our software, our failure to train customers on how to efficiently and effectively use our software, or our failure to provide maintenance services to our customers, may result in negative publicity or legal claims against us. Also, as we continue to expand our customer base, any failure by us to properly provide these services will likely result in lost opportunities for follow-on sales of our software and services.

Our international sales and operations subject us to additional risks that can adversely affect our operating results and financial condition.

        In fiscal 2011 and the first nine months of fiscal 2012, we derived 21% and 24% of our revenues, respectively, from customers outside the United States, and we are continuing to expand our international operations as part of our growth strategy. We currently have sales personnel and sales and support operations in the United States and certain countries across Europe and Asia. However, our sales organization outside the United States is substantially smaller than our sales organization in the United States, and we rely heavily on resellers for non-U.S. sales. Our ability to convince customers to expand their use of our software or renew their maintenance agreements with us is directly correlated to our direct engagement with the customer. To the extent we are unable to engage with non-U.S. customers effectively with our limited sales force capacity or our indirect sales model, we may be unable to grow sales to existing customers to the same degree we have experienced in the United States.

        Our international operations subject us to a variety of risks and challenges, including:

increased management, travel, infrastructure and legal compliance costs associated with having multiple international operations;

reliance on channel partners;

longer payment cycles and difficulties in collecting accounts receivable or satisfying revenue recognition criteria, especially in emerging markets;

increased financial accounting and reporting burdens and complexities;

general economic conditions in each country or region;

17

Table of Contents

economic uncertainty around the world, including recent sovereign debt issues in Europe;

compliance with foreign laws and regulations and the risks and costs of non-compliance with such laws and regulations;

compliance with U.S. laws and regulations for foreign operations, including the Foreign Corrupt Practices Act, the U.K. Bribery Act, import and export control laws, tariffs, trade barriers, economic sanctions and other regulatory or contractual limitations on our ability to sell our software in certain foreign markets, and the risks and costs of non-compliance;

heightened risks of unfair or corrupt business practices in certain geographies and of improper or fraudulent sales arrangements that may impact financial results and result in restatements of financial statements and irregularities in financial statements;

fluctuations in currency exchange rates and related effect on our operating results;

difficulties in repatriating or transferring funds from or converting currencies in certain countries;

the need for localized software and licensing programs;

reduced protection for intellectual property rights in some countries and practical difficulties of enforcing rights abroad; and

compliance with the laws of numerous foreign taxing jurisdictions and overlapping of different tax regimes.

        Any of these risks could adversely affect our international operations, reduce our international revenues or increase our operating costs, adversely affecting our business, operating results and financial condition and growth prospects.

        In addition, compliance with laws and regulations applicable to our international operations increases our cost of doing business in foreign jurisdictions. We may be unable to keep current with changes in government requirements as they change from time to time. Failure to comply with these regulations could have adverse effects on our business. In many foreign countries it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. Although we implemented policies and procedures designed to ensure compliance with these laws and policies, there can be no assurance that all of our employees, contractors, channel partners and agents will comply with these laws and policies. 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 software and services and could have a material adverse effect on our business and results of operations.

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 are subject to U.S. export controls, and we incorporate encryption technology into certain of our products. These encryption products and the underlying technology may be exported outside of the United States only with the required export authorizations, including by license, a license exception or other appropriate government authorizations, including the filing of an encryption registration. We shipped our encryption products prior to obtaining the required export authorizations. Accordingly, we have not fully complied with applicable encryption controls in the Export Administration Regulations. We are in the process of remediating our export compliance procedures to prevent such violations from recurring.

        Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products and services to countries, governments, and persons targeted by U.S. sanctions. While we are taking precautions to prevent our products and services from being shipped to U.S. sanctions targets, we

18

Table of Contents

believe that certain of our products that are available at no cost have been downloaded by persons in countries that are the subject of U.S. embargoes. These free downloads were likely made in violation of U.S. export control and sanctions laws. Based upon our inquiry to date, we believe that we have not had any paying customers in countries sanctioned by the U.S. Government, and have instituted procedures, including IP blocking, that are intended to prevent any downloads from being made into sanctioned countries in the future. In addition, we had not been screening our customers against the U.S. Government lists of prohibited persons, including the Treasury Department's List of Specially Designated Nationals and the Commerce Department's List of Denied Persons. Based upon our inquiry to date, we believe that we do not have any paying customers on any U.S. Government lists of prohibited persons. We are in the process of screening our non-paying customers to determine if we have permitted any free downloads to any prohibited persons. We are also instituting a process for screening all paying and non-paying customers against U.S. Government lists of prohibited persons going forward.

        We are continuing to review this matter and new or different facts may be discovered in the course of our inquiry. In January 2012, we filed Initial Notifications of Voluntary Self Disclosures with the U.S. Department of Commerce's Bureau of Industry and Security, or BIS, and the U.S. Department of Treasury's Office of Foreign Assets Control, or OFAC, concerning these potential violations. Once we complete our review, we will supplement the Initial Notifications by filing Final Disclosures with both agencies. If we are found to be in violation of U.S. sanctions or export control laws, it could result in fines or penalties for us and for individuals, including civil penalties of up to $250,000 or twice the value of the transaction, whichever is greater, per violation, and in the event of conviction for a criminal violation, fines of up to $1 million and possible incarceration for responsible employees and managers for willful and knowing violations. The voluntary disclosure processes with OFAC and BIS are in the initial stages, and we cannot predict when OFAC and BIS will complete their reviews or what enforcement action, if any, they will take.

        We also note that if our channel partners fail to obtain appropriate import, export or re-export licenses or permits, we may also be adversely affected, through reputational harm as well as other negative consequences including government investigations and penalties. We presently incorporate export control compliance requirements in our channel partner agreements. Complying with export control and sanctions regulations for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities.

        In addition, various countries regulate the import of certain encryption technology, including import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our products or could limit our customers' ability to implement our products in those countries. Changes in our products or future changes in export and import regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products globally or, in some cases, prevent the export or import of our products to certain countries, governments, or persons altogether. Any change in export or import regulations, economic sanctions or related legislation, 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 decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, financial condition and results of operations.

If we are unable to maintain successful relationships with our channel partners, our business, operating results and financial condition could be adversely affected.

        In addition to our direct sales force, we use strategic indirect channel partners, such as distribution partners and resellers, to license and support our software. We derive a substantial portion of our revenues from sales of our software through our channel network, particularly in the Europe, Middle East and Africa, or EMEA, and Asia Pacific, or APAC, regions and for sales to government agencies. We expect that

19

Table of Contents

sales through channel partners will continue to grow as a portion of our revenues for the foreseeable future.

        Our agreements with our channel partners are generally non-exclusive, meaning our channel partners may offer customers the products of several different companies, including products that compete with ours. If our channel partners do not effectively market and sell our software, choose to use greater efforts to market and sell their own products or those of our competitors, or fail to meet the needs of our customers, our ability to grow our business and sell our software may be adversely affected. Our channel partners may cease marketing our software with limited or no notice and with little or no penalty. The loss of a substantial number of our channel partners, our possible inability to replace them, or the failure to recruit additional channel partners could materially and adversely affect our results of operations. In addition, sales by channel partners are more likely than direct sales to involve collectibility concerns, in particular sales by our channel partners in developing markets, and accordingly, variations in the mix between revenues attributable to sales by channel partners and revenues attributable to direct sales may result in fluctuations in our operating results.

        Our ability to achieve revenue growth in the future will depend in part on our success in maintaining successful relationships with our channel partners, and to help our channel partners enhance their ability to independently sell and deploy our software. If we are unable to maintain our relationships with these channel partners, or otherwise develop and expand our indirect distribution channel, our business, results of operations, financial condition or cash flows could be adversely affected.

We employ a unique pricing model which subjects us to various challenges that could make it difficult for us to derive expected value from our customers.

        We charge our customers for their use of our software based on the customers' estimated daily indexing capacity. As the amount of machine data within our customers' organizations grows, we may face pressure from our customers regarding our pricing, which could adversely affect our revenues and operating margins. Furthermore, while our software can measure and limit customer usage, such limitations may be improperly circumvented or otherwise bypassed by certain users. Similarly, we provide our customers with an encrypted key for enabling their use of our software. To the extent that a customer improperly copies and distributes the encrypted key to others or uses the encrypted key to install our software on multiple machines, we may not be able to capture the full value for the use of our software. Our enterprise license is meant for our customers' internal use only. If customers improperly make our software available to their customers, for example, through a cloud or managed service offering, it may cannibalize our end user sales or commoditize our software in the market. Additionally, if a customer that has received a volume discount from us offers our software to its end customers, we may experience price erosion and be unable to capture the appropriate value from those end customers.

        Our license agreements generally provide that we can audit our customers' use of our software to ensure compliance with the terms of our license agreement. However, a customer may resist or refuse to allow us to audit their usage, in which case we may have to pursue legal recourse to enforce our rights under the license agreement, which would require us to spend money, distract management and potentially adversely affect our relationship with our customers and users.

Interruptions or performance problems associated with our technology and infrastructure, and our reliance on SaaS technologies from third parties, may adversely affect our business and operating results.

        Our continued growth depends in part on the ability of our existing and potential customers to access our website and download our software or encrypted access keys for our software within an acceptable amount of time. We have experienced, and may in the future experience, website disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, human or software errors, capacity constraints due to an overwhelming number of users accessing our website

20

Table of Contents

simultaneously and denial of service or fraud or security attacks. In some instances, we may not be able to identify the cause or causes of these website performance problems within an acceptable period of time. It may become increasingly difficult to maintain and improve our website performance, especially during peak usage times and as our software becomes more complex and our user traffic increases. If our website is unavailable or if our users are unable to download our software or encrypted access keys within a reasonable amount of time or at all, our business would be negatively affected. We expect to continue to make significant investments to maintain and improve website performance and to enable rapid releases of new features and apps for our software. To the extent that we do not effectively address capacity constraints, upgrade our systems as needed and continually develop our technology and network architecture to accommodate actual and anticipated changes in technology, our business and operating results may be adversely affected.

        In addition, we rely heavily on hosted, Software-as-a-Service, or SaaS, technologies from third parties in order to operate critical functions of our business, including enterprise resource planning services from NetSuite and customer relationship management services from salesforce.com. If these services become unavailable due to extended outages, 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 software and supporting our customers could be impaired until equivalent services, if available, are identified, obtained and implemented, all of which could adversely affect our business.

        Our systems are also vulnerable to damage or interruption from catastrophic occurrences such as earthquakes, floods, fires, power loss, telecommunication failures, terrorist attacks and similar events. Our U.S. corporate offices and certain of the facilities we lease to house our computer and telecommunications equipment are located in the San Francisco Bay Area, a region known for seismic activity. Despite any precautions we may take, the occurrence of a natural disaster or other unanticipated problems at our hosting facilities could result in interruptions, performance problems or failure of our infrastructure.

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

        We offer a trial version of our software to users free of charge as part of our overall strategy of developing the market for software that provides operational intelligence and promoting additional penetration of our software in the markets in which we compete. Some users never convert from the trial version to the paid version of our software. Further, we depend on individuals within an organization who download the trial version of our software being able to convince managers and decision-makers within their organization to convert to a paid version of our software. To the extent that these users do not become or lead to others who become paying customers, we will not realize the intended benefits of this marketing strategy and our ability to grow our revenues will be adversely affected.

If customers demand software that provides operational intelligence via a "Software-as-a-Service" business model, our business could be adversely affected.

        Software-as-a-Service, or SaaS, is a model of software deployment in which a software provider typically licenses an application to customers for use as a service on demand through web browser technologies. While we do not currently offer a commercial version of our product through a SaaS model, we are investing in the development of Splunk Storm, our cloud-based service (currently in beta) that provides a subset of our software's capabilities but is tailored for supporting machine data processing in the cloud. A SaaS business model can require a vendor to undertake substantial capital investments and develop related sales and support resources and personnel. In recent years, companies have begun to expect that key software, such as customer relationship management and enterprise resource planning systems, be provided through a SaaS model. If customers were to require that we provide our product via a SaaS deployment, we would need to direct a significant portion of our capital investments to implement

21

Table of Contents

this alternative business model, which would negatively affect our gross margins. Even if we make these investments, we may be unsuccessful in implementing a SaaS business model. Moreover, sales of a potential future SaaS offering could cannibalize sales of Splunk Enterprise. In addition, the change to a SaaS model would result in changes in the manner in which we recognize revenues. Changes in revenue recognition would affect our operating results and could have an adverse effect on our business, results of operations, financial condition and cash flows.

Our business depends, in part, on sales to the public sector, and significant changes in the contracting or fiscal policies of the public sector could have a material adverse effect on our business.

        We derive a portion of our revenues from contracts with federal, state, local and foreign governments, and we believe that the success and growth of our business will continue to depend on our successful procurement of government contracts. Factors that could impede our ability to maintain or increase the amount of revenues derived from government contracts, include:

changes in fiscal or contracting policies;

decreases in available government funding;

changes in government programs or applicable requirements;

the adoption of new laws or regulations or changes to existing laws or regulations;

potential delays or changes in the government appropriations or other funding authorization processes; and

delays in the payment of our invoices by government payment offices.

        The occurrence of any of the foregoing could cause governments and governmental agencies to delay or refrain from purchasing our software in the future or otherwise have an adverse effect on our business, results of operations, financial condition and cash flows.

Failure to comply with laws or regulations applicable to our business could cause us to lose customers in the public sector or negatively impact our ability to contract with the public sector.

        We must comply with laws and regulations relating to the formation, administration and performance of contracts with the public sector, including U.S. federal, state and local governmental bodies, which affect how we and our channel partners do business in connection with governmental 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, loss of exclusive rights in our intellectual property, and temporary suspension or permanent debarment from government contracting. Any such damages, penalties, disruptions or limitations in our ability to do business with the public sector could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Real or perceived errors, failures or bugs in our software could adversely affect our operating results and growth prospects.

        Because our software is complex, undetected errors, failures or bugs may occur, especially when new versions or updates are released. Our software is often installed and used in large-scale computing environments with different operating systems, system management software, and equipment and networking configurations, which may cause errors or failures of our software or other aspects of the computing environment into which it is deployed. In addition, deployment of our software into complicated, large-scale computing environments may expose undetected errors, failures or bugs in our software. Despite testing by us, errors, failures or bugs may not be found in our software until it is released

22

Table of Contents

to our customers. In the past, we have discovered software errors, failures and bugs in some of our offerings after their introduction. Real or perceived errors, failures or bugs in our software could result in negative publicity, loss of or delay in market acceptance of our software, loss of competitive position or claims by customers for losses sustained by them. In such an event, we may be required, or may choose, for customer relations or other reasons, to expend additional resources in order to help correct the problem.

        In addition, if an actual or perceived failure of our software occurs in a customer's deployment, regardless of whether the failure is attributable to our software, the market perception of the effectiveness of our software could be adversely affected. Alleviating any of these problems could require significant expenditures of our capital and other resources and could cause interruptions, delays or cessation of our licensing, which could cause us to lose existing or potential customers and could adversely affect our operating results and growth prospects.

If our new software and software enhancements do not achieve sufficient market acceptance, our results of operations and competitive position will suffer.

        We spend substantial amounts of time and money to research and develop new and enhanced versions of our existing software to incorporate additional features, improve functionality or other enhancements in order to meet our customers' rapidly evolving demands. In addition, we continue to invest in solutions that can be deployed on top of our core engine to target specific cases and to cultivate our community of application developers and users. When we develop a new or enhanced version of an existing product, we typically incur expenses and expend resources upfront to market, promote and sell the new offering. Therefore, when we develop and introduce new or enhanced products, they must achieve high levels of market acceptance in order to justify the amount of our investment in developing and bringing them to market. For example, if our cloud-based service, Splunk Storm, does not garner widespread market adoption and implementation, our operating results and competitive position could suffer.

        Further, we may make changes to our software that our customers do not like, find useful or agree with. We may also discontinue certain features, begin to charge for certain features that are currently free or increase fees for any of our features or usage of our software.

        Our new software or software enhancements and changes to our existing software could fail to attain sufficient market acceptance for many reasons, including:

failure to predict market demand accurately in terms of software functionality and to supply software that meets this demand in a timely fashion;

defects, errors or failures;

negative publicity about their performance or effectiveness;

delays in releasing our new software or enhancements to our existing software to the market;

introduction or anticipated introduction of competing products by our competitors;

poor business conditions for our end-customers, causing them to delay IT purchases; and

reluctance of customers to purchase software incorporating open source software.

        If our new software or enhancements and changes do not achieve adequate acceptance in the market, our competitive position will be impaired, and our revenues will be diminished. The adverse effect on our operating results may be particularly acute because of the significant research, development, marketing, sales and other expenses we will have incurred in connection with the new software or enhancements.

23

If we are not able to maintain and enhance our brand, our business and operating results may be adversely affected.

        We believe that maintaining and enhancing the "Splunk" brand identity is critical to our relationships with our customers and channel partners and to our ability to attract new customers and channel partners. The successful promotion of our brand will depend largely upon our marketing efforts, our ability to continue to offer high-quality software and our ability to successfully differentiate our software from that of our competitors. Our brand promotion activities may not be successful or yield increased revenues. In addition, independent industry analysts often provide reviews of our product, as well as those of our competitors, and perception of our product in the marketplace may be significantly influenced by these reviews. If these reviews are negative, or less positive as compared to those of our competitors' products and services, our brand may be adversely affected.

        Moreover, it may be difficult to maintain and enhance our brand in connection with sales through channel or strategic partners. The promotion of our brand requires us to make substantial expenditures, and we anticipate that the expenditures will increase as our market becomes more competitive, as we expand into new markets and as more sales are generated through our channel partners. To the extent that these activities yield increased revenues, these revenues may not offset the increased expenses we incur. If we do not successfully maintain and enhance our brand, our business may not grow, we may have reduced pricing power relative to competitors with stronger brands, and we could lose customers and channel partners, all of which would adversely affect our business, results of operations, financial condition and cash flows.

Our future performance depends in part on proper use of our community website, Splunkbase, and support from third-party software developers.

        Our software enables third-party software developers to build apps on top of our machine data engine. We operate a community website that we call Splunkbase for sharing these third party apps, including add-ons and extensions. While we expect Splunkbase to support our sales and marketing efforts, it also presents certain risks to our business, including:

third-party developers may not continue developing or supporting the software apps that they share on Splunkbase;

we cannot provide any assurance that these apps meet the same quality standards that we apply to our own development efforts, and, to the extent they contain bugs or defects, they may create disruptions in our customers' use of our software or negatively affect our brand;

we do not currently provide support for software apps developed by third-party software developers, and users may be left without support and potentially cease using our software if the third-party software developers do not provide support for these apps;

these third-party software developers may not possess the appropriate intellectual property rights to develop and share their apps; and

some of these developers may use the insight they gain using our software and from documentation publicly available on our website to develop competing products.

        Many of these risks are not within our control to prevent, and our brand may be damaged if these apps, add-ons and extensions do not perform to our customers' satisfaction and that dissatisfaction is attributed to us.

If poor advice or misinformation is spread through Splunk Answers, users of our software may experience unsatisfactory results from using our software, which could adversely affect our reputation and our ability to grow our business.

        In addition, as part of Splunkbase, we host a community site called Splunk Answers for sharing knowledge about how to perform certain functions with our software. Our users are increasingly turning to Splunk Answers for support in connection with their use of our software. We do not review or test the information that non-Splunk employees post on Splunk Answers to ensure its accuracy or efficacy in resolving technical issues. Therefore, we cannot ensure that all the information listed on Splunk Answers is accurate or that it will not adversely affect the performance of our software. Furthermore, users who post such information on Splunk Answers may not have adequate rights to the information to share it publicly, and we could be the subject of intellectual property claims based on our hosting of such information. If poor advice or misinformation is spread among users of Splunk Answers, our customers or other users of our software may experience unsatisfactory results from using our software, which could adversely affect our reputation and our ability to grow our business.

Failure to protect our intellectual property rights could adversely affect our business.

        Our success depends, in part, on our ability to protect proprietary methods and technologies that we develop under patent and other intellectual property laws of the United States, so that we can prevent others from using our inventions and proprietary information. If we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology, and our business might be adversely affected. However, defending our intellectual property rights might entail significant expenses. Any of our patent rights, copyrights, trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. As of December 31, 2011, we had one issued U.S. patent covering our machine data technology. We also had two provisional patent applications pending and nine utility patent applications pending for examination in the United States. Finally, we also had five utility patent applications pending for examination in non-U.S. jurisdictions, all of which are counterparts of our U.S. utility patent applications. Our issued patent, and any patents issued in the future, may not provide us with any competitive advantages or may be challenged by third parties, and our patent applications may never be granted. Additionally, the process of obtaining patent 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. Even if issued, there can be no assurance that these 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, allowing other companies to develop offerings 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 United States 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 use the inventions claimed in our issued patents or pending patent applications or otherwise used in our software, 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 software or technology. Effective patent, trademark, copyright and trade secret protection may not be available to us in every country in which our software is available. The laws of some foreign countries may not be as protective of intellectual property rights as those in the United States (in particular, some foreign jurisdictions do not permit patent protection for software), and mechanisms for enforcement of intellectual property rights may be inadequate. Additional uncertainty may result from changes to intellectual property legislation enacted in the United States (including the recent "America Invents Act") and other national governments and from interpretations of the intellectual property laws of

25

Table of Contents

the United States and other countries by applicable courts and agencies. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property.

        We rely in part on trade secrets, proprietary know-how and other confidential information to maintain our competitive position. Although we endeavor to enter into non-disclosure agreements with our employees, licensees and others who may have access to this information, we cannot assure you that these agreements or other steps we have taken will prevent unauthorized use, disclosure or reverse engineering of our technology. Moreover, third parties may independently develop technologies or products that compete with ours, and we may be unable to prevent this competition.

        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. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, we may provoke third parties to assert counterclaims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially viable. 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, results of operations, financial condition and cash flows.

We have been, and may in the future be, subject to intellectual property rights claims by third parties, which are extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.

        Companies in the software and technology industries, including some of our current and potential competitors, own large numbers of patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement or other violations of intellectual property rights. In addition, many of these companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. The litigation may involve patent holding companies or other adverse patent owners that have no relevant product revenues and against which our patents may therefore provide little or no deterrence. We have received, and may in the future receive, notices that claim we have misappropriated, misused, or infringed other parties' intellectual property rights, and, to the extent we gain greater market visibility, we face a higher risk of being the subject of intellectual property infringement claims, which is not uncommon with respect to the enterprise software market. In this regard, we are currently involved in a dispute with respect to the Splunk trademark in the European Union. There may be third-party intellectual property rights, including issued or pending patents, that cover significant aspects of our technologies or business methods. Any intellectual property claims, with or without merit, could be very time-consuming, could be expensive to settle or litigate and could divert our management's attention and other resources. These claims could also subject us to significant liability for damages, potentially including treble damages if we are found to have willfully infringed patents or copyrights. These claims could also result in our having to stop using technology found to be in violation of a third party's rights. We might be required to seek a license for the intellectual property, which may not be available on reasonable terms or at all. Even if a license were available, we could be required to pay significant royalties, which would increase our operating expenses. As a result, we may be required to develop alternative non-infringing technology, which could require significant effort and expense. If we cannot license or develop technology for any infringing aspect of our business, we would be forced to limit or stop sales of our software and may be unable to compete effectively. Any of these results would adversely affect our business, results of operations, financial condition and cash flows.

26

Table of Contents

Our use of "open source" software could negatively affect our ability to sell our software and subject us to possible litigation.

        We use open source software in our software and expect to continue to use open source software in the future. We may face claims from others claiming ownership of, or seeking to enforce the terms of, an open source license, including by demanding release of the open source software, derivative works or our proprietary source code that was developed using such software. These claims could also result in litigation, require us to purchase a costly license or require us to devote additional research and development resources to change our software, any of which would have a negative effect on our business and operating results. In addition, if the license terms for the open source code change, we may be forced to re-engineer our software or incur additional costs. Finally, we cannot assure you that we have not incorporated additional open source software in our software in a manner that is inconsistent with our current policies and procedures.

If our security measures are breached or unauthorized access to customer data is otherwise obtained, our software may be perceived as not being secure, customers may reduce the use of or stop using our software, and we may incur significant liabilities.

        Our software involves the storage and transmission of data, and security breaches could result in the loss of this information, litigation, indemnity obligations and other liability. While we have taken steps to protect the confidential information that we have access to, including confidential information we may obtain through our customer support services or customer usage of Splunk Storm, our cloud-based service currently in beta, we do not have the ability to monitor or review the content that our customers store, and therefore, we have no direct control over the substance of the content. Therefore, if customers use our software for the transmission or storage of personally identifiable information and our security measures are breached as a result of third-party action, employee error, malfeasance or otherwise, our reputation could be damaged, our business may suffer, and we could incur significant liability. Because techniques used to obtain unauthorized access or sabotage systems change frequently and generally are not identified until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any or all of these issues could negatively impact our ability to attract new customers and increase engagement by existing customers, cause existing customers to elect to not renew their subscriptions, or subject us to third-party lawsuits, regulatory fines or other action or liability, thereby adversely affecting our operating results.

Because our software could be used to collect and store personal information, domestic and international privacy concerns could result in additional costs and liabilities to us or inhibit sales of our software.

        Personal privacy has become a significant issue in the United States and in many other countries where we offer our software. The regulatory framework for privacy issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. Many federal, state and foreign government bodies and agencies have adopted or are considering adopting laws and regulations regarding the collection, use and disclosure of personal information. In the United States, these include rules and regulations promulgated under the authority of the Federal Trade Commission, the Health Insurance Portability and Accountability Act (HIPAA) of 1996 and state breach notification laws. Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy legal framework with which we or our customers must comply, including the Data Protection Directive established in the European Union and the Federal Data Protection Act recently implemented in Germany.

        In addition to government regulation, privacy advocates and industry groups may propose new and different self-regulatory standards that either legally or contractually apply to us. Because the interpretation and application of privacy and data protection laws are still uncertain, it is possible that these laws may be interpreted and applied in a manner that is inconsistent with our existing data management practices or the features of our software. If so, in addition to the possibility of fines, lawsuits

27

Table of Contents

and other claims, we could be required to fundamentally change our business activities and practices or modify our software, which could have an adverse effect on our business. Any inability to adequately address privacy concerns, even if unfounded, or comply with applicable privacy or data protection laws, regulations and policies, could result in additional cost and liability to us, damage our reputation, inhibit sales and adversely affect our business.

        Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations, and policies that are applicable to the businesses of our customers may limit the use and adoption of, and reduce the overall demand for, our software. Privacy concerns, whether valid or not valid, may inhibit market adoption of our software particularly in certain industries and foreign countries.

Federal, state and industry regulations as well as self-regulation related to privacy and data security concerns pose the threat of lawsuits and other liability.

        We may collect and utilize demographic and other information, including personally identifiable information, from and about users (such as customers, potential customers, and others) as they interact with Splunk over the internet and otherwise provide us with information whether via our website, through email, or through other means. Users may provide personal information to us in many contexts such as when signing up for certain services, registering for seminars, participating in a survey, when answering questions on Splunk Answers, when posting reviews or otherwise commenting on Splunk apps, when using other community or social networking features, when participating in polls or when signing up to receive e-mail newsletters.

        Within the United States, various federal and state laws and regulations govern the collection, use, retention, sharing and security of the data we receive from and about users. Outside of the United States, various jurisdictions actively regulate and enforce laws regarding the collection, retention, transfer, and use (including loss and unauthorized access) of personal information. Privacy advocates and government bodies have increasingly scrutinized the ways in which companies link personal identities and data associated with particular users or devices with data collected through the internet, and we expect such scrutiny to continue to increase. Loss, retention or misuse of certain information and alleged violations of laws and regulations relating to privacy and data security, and any relevant claims, may expose us to potential liability and may require us to expend significant resources on data security and in responding to and defending such allegations and claims.

If we are unable to attract and retain key personnel, our business could be adversely affected.

        We depend on the continued contributions of our senior management and other key personnel, the loss of whom could adversely affect our business. All of our executive officers and key employees are at-will employees, which means they may terminate their employment relationship with us at any time. We do not maintain a key-person life insurance policy on any of our officers or other employees.

        Our future success also depends on our ability to identify, attract and retain highly skilled technical, managerial, finance and other personnel, particularly in our sales and marketing, research and development, general and administrative, and professional service departments. For example, we are actively recruiting a Senior Vice President of Product Development, an important role that we will need to fill as we continue to grow. We face intense competition for qualified individuals from numerous software and other technology companies. In addition, competition for qualified personnel, particularly software engineers, is particularly intense in the San Francisco Bay Area, where our headquarters are located. We may incur significant costs to attract and retain them, and we may lose new employees to our competitors or other technology companies before we realize the benefit of our investment in recruiting and training them. As we move into new geographies, we will need to attract and recruit skilled personnel in those areas. If we are 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, our business will be adversely affected.

28

Table of Contents

        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, conversely, 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, or if we need to increase our compensation expenses to retain our employees, our business, results of operations, financial condition and cash flows would be adversely affected.

Prolonged economic uncertainties or downturns could materially adversely affect our business.

        Current or future economic downturns could adversely affect our business and results of operations. Negative conditions in the general economy both in the United States and abroad, including conditions resulting from financial and credit market fluctuations and terrorist attacks on the United States, Europe, Asia Pacific or elsewhere, could cause a decrease in corporate spending on enterprise software in general and negatively affect the rate of growth of our business.

        General worldwide economic conditions have experienced a significant downturn and continue to remain unstable. These conditions make it extremely difficult for our customers and us to forecast and plan future business activities accurately, and they could cause our customers to reevaluate their decision to purchase our product, which could delay and lengthen our sales cycles or result in cancellations of planned purchases. Furthermore, during challenging economic times our customers may face issues in gaining timely access to sufficient credit, which could result in an impairment of their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts, which would adversely affect our financial results.

        We have a significant number of customers in the business services, financial services, healthcare and pharmaceuticals, high technology, manufacturing, media and entertainment, online services, retail, telecommunications and travel and transportation industries. A substantial downturn in any of these industries may cause firms to react to worsening conditions by reducing their capital expenditures in general or by specifically reducing their spending on information technology. Customers in these industries may delay or cancel information technology projects or seek to lower their costs by renegotiating vendor contracts. To the extent purchases of our software are perceived by customers and potential customers to be discretionary, our revenues may be disproportionately affected by delays or reductions in general information technology spending. Also, customers may choose to develop in-house software as an alternative to using our products. Moreover, competitors may respond to market conditions by lowering prices and attempting to lure away our customers. In addition, the increased pace of consolidation in certain industries may result in reduced overall spending on our software.

        We cannot predict the timing, strength or duration of any economic slowdown, instability or recovery, generally or within any particular industry. If the economic conditions of the general economy or industries in which we operate worsen from present levels, our business, results of operations, financial condition and cash flows could be adversely affected.

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.

        We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new features or enhance our software, improve our operating infrastructure or acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders

29

Table of Contents

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 that we may secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may 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 impaired, and our business may be adversely affected.

Future acquisitions could disrupt our business and adversely affect our results of operations, financial condition and cash flows.

        We may choose to expand by making acquisitions that could be material to our business, results of operations, financial condition and cash flows. Our ability as an organization to successfully acquire and integrate technologies or businesses is unproven. Acquisitions involve many risks, including the following:

an acquisition may negatively affect our results of operations, financial condition or cash flows because it may require us to incur charges or assume substantial debt or other liabilities, may cause adverse tax consequences or unfavorable accounting treatment, may expose us to claims and disputes by third parties, including intellectual property claims and disputes, or may not generate sufficient financial return to offset additional costs and expenses related to the acquisition;

we may encounter difficulties or unforeseen expenditures in integrating the business, technologies, products, personnel or operations of any company that we acquire, particularly if key personnel of the acquired company decide not to work for us;

an acquisition may disrupt our ongoing business, divert resources, increase our expenses and distract our management;

an acquisition may result in a delay or reduction of customer purchases for both us and the company acquired due to customer uncertainty about continuity and effectiveness of service from either company;

we may encounter difficulties in, or may be unable to, successfully sell any acquired products;

an acquisition may involve the entry into geographic or business markets in which we have little or no prior experience or where competitors have stronger market positions;

our use of cash to pay for acquisition would limit other potential uses for our cash;

if we incur debt to fund such acquisition, such debt may subject us to material restrictions on our ability to conduct our business as well as financial maintenance covenants; and

to the extent that we issue a significant amount of equity securities in connection with future acquisitions, existing stockholders may be diluted and earnings per share may decrease.

        The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition and cash flows.

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

        As we continue to expand our international operations, we become more exposed to the effects of fluctuations in currency exchange rates. Our sales contracts are denominated in U.S. dollars, and therefore substantially all of our revenues are not subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our software to our customers outside of the United States, which could adversely affect our business, results of operations, financial condition and cash flows. We

30

Table of Contents

incur expenses for employee compensation and other operating expenses at our non-U.S. locations in the local currency. Fluctuations in the exchange rates between the U.S. dollar and other currencies could result in the dollar equivalent of such expenses being higher. This could have a negative impact on our reported operating results. To date, we have not engaged in any hedging strategies, and any such strategies, such as forward contracts, options and foreign exchange swaps related to transaction exposures that we may implement to mitigate this risk may not eliminate our exposure to foreign exchange fluctuations.

The enactment of legislation implementing changes in the U.S. taxation of international business activities or the adoption of other tax reform policies could materially impact our financial position and results of operations.

        Recent changes to U.S. tax laws, including limitations on the ability of taxpayers to claim and utilize foreign tax credits and the deferral of certain tax deductions until earnings outside of the United States are repatriated to the United States, as well as changes to U.S. tax laws that may be enacted in the future, could impact the tax treatment of our foreign earnings. Due to expansion of our international business activities, any changes in the U.S. taxation of such activities may increase our worldwide effective tax rate and adversely affect our financial position and results of operations.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

        In general, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an "ownership change" is subject to limitations on its ability to utilize its pre-change net operating losses, or NOLs, to offset future taxable income. Our existing NOLs may be subject to limitations arising from previous ownership changes, and if we undergo an ownership change in connection with or after this offering, our ability to utilize NOLs could be further limited by Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under Section 382 of the Code. Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. For these reasons, we may not be able to utilize a material portion of the NOLs reflected on our balance sheet, even if we attain profitability.

Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use, value added or similar taxes, and we could be subject to liability with respect to past or future sales, which could adversely affect our results of operations.

        We do not collect sales and use, value added and similar taxes in all jurisdictions in which we have sales, based on our belief that such taxes are not applicable. Sales and use, value added and similar tax laws and rates vary greatly by jurisdiction. Certain jurisdictions in which we do not collect such taxes may assert that such taxes are applicable, which could result in tax assessments, penalties and interest, and we may be required to collect such taxes in the future. Such tax assessments, penalties and interest or future requirements may adversely affect our results of operations.

Our international operations subject us to potentially adverse tax consequences.

        We generally conduct our international operations through wholly owned subsidiaries and report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. We are in the process of organizing our corporate structure to more closely align with the international nature of our business activities. Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher

effective tax rates, reduced cash flows and lower overall profitability of our operations. We believe that our financial statements reflect adequate reserves to cover such a contingency, but there can be no assurances in that regard.

We could be subject to additional tax liabilities.

        We are subject to federal, state and local taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in evaluating our tax positions and our worldwide provision for taxes. During the ordinary course of business, there are many activities and transactions for which the ultimate tax determination is uncertain. We recently discovered that we have not complied with various tax rules and regulations in certain foreign jurisdictions. We are working to resolve these matters. In addition, our tax obligations and effective tax rates could be adversely affected by changes in the relevant tax, accounting and other laws, regulations, principles and interpretations, including those relating to income tax nexus, by our earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, by changes in foreign currency exchange rates, or by changes in the valuation of our deferred tax assets and liabilities. We may be audited in various jurisdictions, and such jurisdictions may assess additional taxes against us. Although we believe our tax estimates are reasonable, the final determination of any tax audits or litigation could be materially different from our historical tax provisions and accruals, which could have a material adverse effect on our operating results or cash flows in the period or periods for which a determination is made.

Risks Related to Ownership of Our Common Stock and this Offering

There has been no prior market for our common stock and an active market may not develop or be sustained and investors may not be able to resell their shares at or above the initial public offering price.

        There has been no public market for our common stock prior to this offering. The initial public offering price for our common stock will be determined through negotiations between the underwriters and us and may vary from the market price of our common stock following this offering. If you purchase shares of our common stock in this offering, you may not be able to resell those shares at or above the initial public offering price. An active or liquid market in our common stock may not develop upon completion of this offering or, if it does develop, it may not be sustainable.

Our stock price may be volatile or may decline regardless of our operating performance resulting in substantial losses for investors purchasing shares in this offering.

        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 numerous factors, many of which are beyond our control, including:

actual or anticipated fluctuations in our operating results;

the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

failure of securities analysts to initiate or maintain coverage of our company, changes in financial estimates by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;

ratings changes by any securities analysts who follow our company;

announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures or capital commitments;

changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;

32

Table of Contents

price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;

any major change in our board of directors or management;

lawsuits threatened or filed against us; and

other events or factors, including those resulting from war, incidents of terrorism or responses to these events.

        In addition, the stock markets, and in particular the market on which our common stock will be listed, have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business, results of operations, financial condition and cash flows.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our share 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, our market and our competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share 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 share price or trading volume to decline.

We may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a return.

        We expect to use the net proceeds we receive from this offering for capital expenditures and for general corporate purposes, including working capital, sales and marketing activities, product development, and general and administrative matters. We may also use a portion of the net proceeds to acquire complementary businesses, products, services or technologies. We do not have any agreements or commitments for any acquisitions at this time. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not increase the value of our business, which could cause our stock price to decline.

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

        The market price of shares of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers and significant stockholders, a large number of shares of our common stock becoming available for sale or the perception in the market that holders of a large number of shares intend to sell their shares. After this offering, we will have outstanding                        shares of our common stock, based on the number of shares outstanding as of                                    , 2012. This includes the shares included in this offering, which may be resold in the public market immediately. The remaining                                    shares, or        % of our outstanding shares after this offering, are currently restricted as a result of lock-up agreements but will be able to be sold in the near future as set forth below.

        After this offering, the holders of an aggregate of                                    shares of our common stock as of                                    , 2012 will have rights, subject to some conditions, to require us to file registration

33

statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders. Substantially all of these shares are subject to lock-up agreements restricting their sale for 180 days after the date of this prospectus, subject to potential extension in the event we release earnings results or a material event relating to us occurs near the end of the lock-up period. We also intend to register shares of common stock that we may issue under our employee equity incentive plans. Once we register these shares, they will be able to be sold freely in the public market upon issuance, subject to existing lock-up agreements. Morgan Stanley & Co. LLC may, in its sole discretion, permit our officers, directors, employees and current stockholders who are subject to the 180-day contractual lock-up to sell shares prior to the expiration of the lock-up agreements. The 180-day lock-up period is subject to extension in some circumstances.

Purchasers in this offering will experience immediate and substantial dilution in the book value of their investment.

        The initial public offering price per share will be substantially higher than the pro forma net tangible book value per share of our common stock outstanding prior to this offering. As a result, investors purchasing common stock in this offering will experience immediate dilution of $            per share. This dilution is due in large part to the fact that our earlier investors paid substantially less than the initial public offering price when they purchased their shares of common stock. In addition, we have issued options to acquire common stock at prices significantly below the initial public offering price. To the extent outstanding options are ultimately exercised, there will be further dilution to investors in this offering. In addition, if the underwriters exercise their option to purchase additional shares from us or if we issue additional equity securities, you will experience additional dilution.

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

        As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of the                                    and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management's attention may be diverted from other business concerns, which could adversely affect our business and operating results. Although we have already hired additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which will increase our costs and expenses.

        In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management's time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and

practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affected.

        We also expect that being a public company and these new rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

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

As a result of becoming a public company, we will be obligated to develop and maintain proper and effective internal control over financial reporting. We may not complete our analysis of our internal control over financial reporting in a timely manner, or these internal controls may not be determined to be effective, which may adversely affect investor confidence in our company and, as a result, the value of our common stock.

        We will be required, pursuant to Section 404 of the Sarbanes–Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting for the fiscal year ended January 31, 2014. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on our internal control over financial reporting.

        We are in the very early stages of the costly and challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are effective.

        If we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline, and we may be subject to investigation or sanctions by the SEC.

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

        We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

        Provisions in our certificate of incorporation and bylaws, as amended and restated in connection with this offering, may have the effect of delaying or preventing a change of control or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:

authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights and preferences determined by our board of directors;

require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;

specify that special meetings of our stockholders can be called only by our board of directors, the Chairman of our board of directors, or our Chief Executive Officer;

establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of persons for election to our board of directors;

establish that our board of directors is divided into three classes, Class I, Class II and Class III, with each class serving three-year staggered terms;

prohibit cumulative voting in the election of directors;

provide that our directors may be removed only for cause;

provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum; and

require the approval of our board of directors or the holders of a supermajority of our outstanding shares of capital stock to amend our bylaws and certain provisions of our certificate of incorporation.

        These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any "interested" stockholder for a period of three years following the date on which the stockholder became an "interested" stockholder.

Our directors, executive officers and significant stockholders will continue to have substantial control over us after this offering and could delay or prevent a change in corporate control.

        After this offering, our directors, executive officers and holders of more than 5% of our common stock, together with their affiliates, will beneficially own, in the aggregate,        % of our outstanding common stock. As a result, these stockholders, acting together, would have the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, would have the ability to control the management and affairs of our company. Accordingly, this concentration of ownership might adversely affect the market price of our common stock by:

delaying, deferring or preventing a change in control of the company;

impeding a merger, consolidation, takeover or other business combination involving us; or

discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of the company.
