Item 1.    Business

Overview

        Splunk provides an innovative software platform that enables organizations to gain real-time operational intelligence by harnessing the value of their machine data. Our software collects and indexes data at massive scale, regardless of format or source, and enables users to quickly and easily search, correlate, analyze, monitor and report on this data in real time. We believe our software addresses the risks, challenges and opportunities organizations face with increasingly large and diverse data sets, commonly referred to as big data, and is specifically tailored for machine-generated data.

        Machine data is generated by software applications, information technology (IT) infrastructure, electronic devices and systems. The applications, servers, network devices, desktop and laptop computers, mobile devices and various other systems that organizations have deployed to support their operations continuously generate information relating to their status and activities. Machine data can be found in a variety of formats such as application log files, call detail records, clickstream data associated with user website interactions, data files, system configuration files, alerts and tickets. It is generated by both machine-to-machine as well as human-to-machine interactions.

        Outside of an organization's traditional IT infrastructure, every processor-based system, including HVAC controllers, smart electrical meters, GPS devices and radio-frequency identification tags, and many consumer-oriented systems, such as mobile devices, automobiles and medical devices that contain embedded electronic devices, are also continuously generating machine data. Machine data can be structured or unstructured and contain a definitive, time-stamped record of various activities, such as transactions, customer and user activities, and security threats. Our software is intended to help users in various roles, including IT, cybersecurity and business professionals, quickly analyze their machine data and realize real-time visibility into and intelligence about their organization's operations. We believe this operational intelligence enables organizations to improve service levels, reduce costs, mitigate security risks, demonstrate and maintain compliance and gain new customer and business insights that enable them to drive better decisions.

        The core of our software is a proprietary machine data engine, comprised of collection, indexing, search and data management capabilities. Our software can collect and index hundreds of terabytes of information daily, irrespective of format or source. Our machine data engine uses our proprietary data architecture that enables dynamic schema creation on the fly, enabling users to run queries on data without having to understand the structure of the data prior to collection and indexing. Our machine data fabric for data collection and indexing delivers speed and scalability when processing massive amounts of machine data. Our software leverages improvements in the cost and performance of commodity computing and can be deployed in a wide variety of computing environments, from a single laptop to large globally distributed data centers.

        We complement our core product with additional content ("apps" and "add-ons") that can be deployed on top of our core data engine. These apps and add-ons, which are generally available for download via our Splunkbase website, provide incremental functionality in the form of pre-built data inputs, searches, reports, alerts and dashboards. Most of these apps and add-ons have typically been available for free download, but there are also premium apps, developed by Splunk and third party developers in the Splunk community, who charge for content, such as the Splunk App for Enterprise Security and Splunk App for PCI Compliance. We, along with a number of third-party developers and customers, have developed hundreds of apps and add-ons for specific use cases in our core and adjacent markets. Examples of apps and add-ons that we developed and currently offer include Splunk App for Enterprise Security, Splunk App for PCI Compliance, Splunk App for VMware, Splunk App for Microsoft Exchange, Splunk App for Microsoft Active Directory, Splunk DB Connect, Splunk Hadoop Connect and the Splunk App for Hadoop Operations. These apps make it easier and faster for our customers to extend the value of their machine data and the Splunk platform to solve specific use

cases. This software content has also enabled Splunk to target new markets and disrupt markets traditionally served by point solutions. Often, as customers use additional apps, this generates expanded usage, licensing and revenues for our core platform.

        As part of our strategy to offer an open platform, we provide application programming interfaces (APIs) and software development kits (SDKs) in various programming languages. These enable developers to build apps that run on top of Splunk software and to integrate their Splunk apps and data with other parts of their IT infrastructure. In fiscal 2013 we also released Splunk Storm that provides, on a subscription basis, a subset of our Splunk Enterprise software's capabilities as a cloud-based service and is presently tailored for cloud-based developers and applications running in the cloud.

        Our online user communities, Splunkbase and Splunk Answers, provide our customers with an environment to share these apps, collaborate on the use of our software and provide community-based support. We believe this user-driven ecosystem results in greater use of our software and drives cost-effective marketing, increased brand awareness and viral adoption of our product.

        Our software is designed to accelerate return-on-investment for our customers. It does not require customization, long deployment cycles or extensive professional services commonly associated with traditional enterprise software applications. Users can simply download and install the software, typically in a matter of hours, to connect to their relevant machine data sources. We also offer support, training and professional services to our customers to assist in the deployment of our software.

        Our mission is to make machine data accessible, usable and valuable to everyone in an organization. Splunk's intuitive, browser-based approach to analyzing machine data makes our software easy to use and extend, allowing both technical and non-technical users to, with minimal training, use our products. Our customers leverage our software for various use cases, including infrastructure and operations management, applications management, security and compliance, business and web analytics, and scientific and industrial applications, among many others. Our software helps users derive new insights from machine data that can be used to, among other things, improve service levels, reduce operational costs, mitigate security risks, demonstrate and maintain compliance, and drive better business decisions. The result is a new level of operational visibility enabling more informed business decisions that can provide a competitive advantage for our customers.

        As of January 31, 2013, we had over 5,200 Splunk Enterprise customers, including over 60 of the Fortune 100. Our Splunk Enterprise customers pay license fees generally based on their estimated peak daily indexing capacity needs. Our Splunk Storm customers pay a monthly subscription fee based on the amount of data stored. For fiscal 2013, 2012 and 2011, our revenues were $198.9 million, $121.0 million and $66.2 million, respectively, representing year-over-year growth of 64% for fiscal 2013 and 83% for fiscal 2012, and our net loss was $36.7 million, $11.0 million and $3.8 million, respectively.

Our Growth Strategy

        Our goal is to make our software the platform for delivering operational intelligence and real-time business insights from machine data. The key elements of our strategy are to:

        Extend our technological capabilities.    We intend to continue to invest heavily in our product development efforts to deliver additional features, address customer needs and enable solutions that can address new end markets. We will continue to expand into adjacent product and technology areas that enable organizations to further unlock the value of their machine data.

        Continue to expand our direct and indirect sales organization, including our channel relationships, to acquire new customers.    We will continue to increase investments in our sales and marketing organizations to drive acquisition of new customers across geographies and industries. We will continue to expand our sales operations globally to support new and existing customers in these regions. We will continue to invest in and foster the growth of our channel relationships, particularly outside the United

5

Table of Contents

States where channel partners provide greater sales leverage and play a greater role in the sales process.

        Further penetrate our existing customer base.    We will continue to cultivate incremental sales from our existing customers by driving increased use of our software within organizations. In particular, we continue to seek to upsell existing customers increased license capacity for additional deployments and new use cases which will drive higher daily indexing needs. We believe our existing customer base serves as a strong source of incremental revenues given the horizontal applicability of our software and the growing machine data volumes our customers face. Our sales teams are responsible for driving renewals of existing contracts as well as increased adoption of our software by existing customers.

        Develop additional solutions in adjacent markets as well as products that enable organizations to use our software in different ways.    We believe there is a significant opportunity to provide additional solutions that leverage our core machine data engine to help organizations understand and unlock the value of their machine data in specific end markets and use cases. For example, our Splunk App for Enterprise Security enables customers to effectively target enterprise security events. We will continue to invest in both our core machine data engine as well as end-market specific packaged solutions to drive Splunk market penetration, expand our addressable market opportunity and make Splunk a more targeted solution for the machine data problems our customers and prospects encounter.

        Grow our user communities and partner ecosystem to increase awareness of our brand, target new use cases, drive operational leverage and deliver more targeted, higher value solutions.    We believe our user community has the potential to provide significant operating leverage by delivering apps that extend our software's functionality to new use cases. We will continue to invest in business development initiatives in order to add additional OEM and strategic relationships to enable new sales channels for our software as well as extend our integration with third party products. In addition, once these relationships have been established, we expect that OEM vendors and managed service providers will invest in and create customized application functionality based on our machine data engine.

        Become the developer platform for machine data.    We intend to continue our investments in SDKs and APIs that help software developers leverage the functionality of our machine data engine. Our SDKs enable developers to build solutions that deeply integrate the functionality of our machine data engine and machine data fabric as well as access the data stored in the data indexes. Through our investments in SDKs and APIs, we intend to promote and extend the capabilities of our platform to customers who wish to build sophisticated applications and interfaces that leverage our software.

Splunk Technology

        We believe our investments in our product and key technologies drive significant competitive differentiation. The key technologies of our software are architected to handle large volumes of machine data at a massive scale with minimal overhead. Our software platform is highly flexible and is able to collect and index large amounts of heterogeneous data formats, from physical, virtual and/or cloud environments.

        Schema-on-the-fly.    Our software collects and indexes data irrespective of source and format. Rather than requiring that data be input into a pre-defined structure, our software's schema-on-the-fly technology creates structure as it searches the data from a single query, allowing users to ask new and different questions at any time without having to re-architect a schema as would be required in a relational database. Our software builds schema in real time and does not require any user intervention or pre-defined knowledge about the data it is processing. Our software allows different users to run a variety of queries, regardless of changes in format to the data being input into the system.

Table of Contents

        Machine data fabric.    Our software enables users to process machine data no matter the infrastructure topology, from a single machine to a globally distributed, virtualized IT infrastructure. This machine data fabric allows customers to address the complexities of handling massive amounts of real-time, dynamic, heterogeneous machine data. Our APIs enable users to forward data from our software to other parts of their IT network, creating a machine data fabric across the organization irrespective of whether the data is used by our software for analysis and reporting or as a conduit to other systems.

        Search processing language.    Our software provides a proprietary search language that is specifically designed for working with machine data. Our search language supports basic arithmetic operations to refine searches and conduct calculations with the results of a query in real time. Statistical and reporting commands native to our search language let users perform more robust calculations and analysis. Our software can also learn about the structure of the machine data through the searches users conduct, allowing users to utilize the machine data structure and knowledge garnered by previous Splunk searches.

        Our software contains the following features and functionality:

        Splunk's technology contains a number of important components:

        Collection.    Our software collects machine data from a number of different sources across a distributed environment including servers, network devices, desktop and laptop computers, mobile

devices and various other systems that organizations have deployed to support their operations. Our software acts as a recording mechanism, collecting, storing and making available all of the machine data that it receives.

        Indexing.    Our proprietary indexing technology allows for real-time indexing of any data collected by our software regardless of its source or format and without the use of any specific parsers or data connectors. Our software indexes the data and stores the data in a scalable storage format, which can reside on commodity servers and storage devices. Our software stores both the raw data and the index in an efficient, compressed, flat file format.

        Search.    Our software enables users to search through the massive amounts of machine data that have been indexed and stored. At its most basic level, the search engine allows users to type and search for keywords or data fields that are of interest. This foundational capability forms the basis for deriving business insights from our dashboards and customized views. Users can leverage our search language and functionality to filter through indexed data and refine search results to obtain more precise information.

        Core functions.    Our software's core functionality includes alerts, access control, statistics and correlation capabilities. With our software's granular, role-based access, an administrator can control various aspects of a given user's search including the data to which the user has access as well as what portions of the data may be visible in results. Search results and reports can be defined according to a particular user's business function and level of access. Different users can see completely different views on the same data, depending on what is important to them.

        SDKs and APIs.    Our SDKs allow third-party software developers to build applications on top of our software. Our APIs allow users to access the machine data stored within the Splunk instance as well as access machine data engine functionality from third party software.

        Apps.    We provide the ability for users to write their own lightweight apps using standard Web technologies, such as HTML and CSS, XML and a variety of SDKs, as well as our query language, to provide incremental functionality targeting a particular use case. The SDKs enable developers to create apps and integrate Splunk into their IT infrastructure, using common programming languages such as Java, Javascript, Python and PHP.

        Splunk Storm is used by organizations developing applications on cloud platforms, such as Amazon Web Services (AWS), Heroku, Google App Engine and Rackspace. Splunk Storm enables users to diagnose and troubleshoot application problems, gain rapid visibility and insight into cloud-based applications and monitor critical business metrics for more effective operational intelligence.

        Customers can deploy our software directly on-premises through the purchase of Splunk Enterprise or subscribe to Splunk Storm, our cloud-based service, based on their daily indexing capacity needs.

        For Splunk Enterprise (on-site) deployments, our software can be deployed in a variety of environments ranging from a single laptop to a distributed enterprise IT environment handling massive amounts of data. Our customers use Splunk forwarders, indexers, and search heads to create a machine data fabric that allows for the efficient, secure and real-time collection and indexing of machine data regardless of network, data center or IT infrastructure topology. The diagram below shows a

representative Splunk deployment topology in a distributed environment making use of our machine data fabric:


Massive Linear Scalability to Hundreds of TBs/Day

GRAPHIC

        This distributed machine data processing architecture illustrated above provides near-linear scalability, resulting in the ability to index and search across hundreds of terabytes of data. Our software can operate in a single data center or across multiple data centers both inside and outside an organization, and all from a single user interface. This architecture also allows for flexible deployment of hardware, as commodity hardware can be added as needed.

        For Splunk Storm (cloud) deployments, machine data is sent from the customer to Splunk Storm using network streams such as syslog, or Splunk forwarders. The universal forwarder can be used to gather data from a variety of inputs and forward the data to Splunk Storm for cloud-based indexing and searching. Splunk Storm is presently aimed at organizations that develop and run applications in the public cloud.

Services

        While users can easily download, install and deploy our software on their own, certain enterprise customers that have large, highly complex IT environments or deployment requirements may choose to leverage our customer support and professional services organization. Many users leverage the community-based support of Splunkbase and Splunk Answers before engaging with our customer support or services organizations. Some of our certified partners also provide limited, first level support and professional services before a customer reaches out to our internal Splunk customer support and professional services teams.

Table of Contents

        Our customers typically purchase one year of software maintenance and support as part of their initial purchase of our products, with an option to renew their maintenance agreements. These maintenance agreements provide customers the right to receive unspecified software updates, maintenance releases and patches and access to our technical support services during the term of the agreement.

        We maintain a customer support organization that offers multiple service levels for our customers based on their needs. These customers receive guaranteed response times, direct telephonic support and access to online support portals. Our highest levels of support provide 24x7x365 support for critical issues, a designated resource to manage the account and quarterly reviews of the customer's deployments. Our customer support organization has global capabilities, delivering support in multiple languages with deep expertise in both our software as well as complex IT environments and associated third party infrastructure.

        We offer training services to our customers and channel partners through our education and training organization. We have also implemented a training certification program to ensure an understanding of our products and services.

        We provide consulting and implementation services to customers through our professional services team. They are typically utilized by large enterprises looking to deploy our software across their large, disparate and complex IT infrastructure. We generally provide these services at the time of initial installation to help the customer with configuration and implementation. Given our software's ease-of-use, our professional services engagements are typically short in duration and last from a few days to up to several weeks.

Partner and Developer Ecosystem

        We have OEM relationships with a select group of partners who integrate our software into their product offerings to provide additional reporting, monitoring and analytic capabilities within their own products. With respect to our OEM relationships, we provide our partners with a limited use license to expose certain data and analytics functionalities in their products, for which they generally pay us a royalty based on units shipped.

        We engage with Managed Service Providers, who use Splunk software to offer services based on our software, such as for security, PCI compliance and log management. These services are typically offered on a subscription basis, for which we are paid license fees based on monthly indexing volume.

        We have partnered with several leading technology companies to build Splunk apps that allow users to capture data and gain insights into the partner's respective products. Several technology partners offer apps for free via Splunkbase. These apps typically consist of collections of reports, dashboards and data extractions which put our software in context for users of those specific technologies and allow them to easily and quickly understand the performance of their IT systems or correlate this data with other data sources.

Table of Contents

        We offer a developer license that allows third party developers to build software using Splunk's existing developer framework and we have published information about our APIs to enable developers to build new user interfaces on top of our core engine. We are creating additional SDKs based on various programming languages to make our software more extensible and allow developers to build applications and services on our platform that extend its functionality.

Splunk Community

        Our online communities provide us with a rapidly growing network of active users who promote the usage of our software and provide technical support to each other.

        Our online communities include Splunkbase, our apps repository, Splunk Answers, our community collaboration site, and Splunk Dev, where developers can download SDKs, access API documentation and see sample code for building software on our core engine. We also maintain active communities on leading social internet platforms, including Facebook and LinkedIn.

        Splunkbase.    Users and partners contribute and share custom lightweight apps and add-ons that run on our software. Generally, these lightweight apps provide pre-built functionality that addresses specific use cases. Currently, we have hundreds of apps available for download on Splunkbase. We do not receive any revenues from the sale of apps by third party application providers, as most apps posted to Splunkbase are free. Partner apps listed on Splunkbase, which are not free are licensed directly by the third party to the end user.

        Splunk Answers.    Users ask questions in an online community forum and share best practices about how to build searches, create data visualizations and configure and deploy our software. While our product, support, engineering and professional services teams participate in the Splunk Answers forum, as of January 31, 2013, approximately two-thirds of questions appearing on Splunk Answers were answered by non-Splunk personnel, largely the result of a growing, active user community.

        Splunk Dev.    In addition to documentation about the Splunk APIs and SDKs, our developer portal contains documentation about best practices for building machine data output into third party software.

        We also promote and support offline meetings for our community, including regional user group meetings and an annual user conference.

Sales and Marketing

        Our sales and marketing organizations work together closely to drive market awareness, build a strong sales pipeline, and cultivate customer relationships to drive revenue growth.

        We sell our software through direct field sales, direct inside sales and indirect channel sales. We gather prospects through a broad range of marketing programs and events and through users who download our trial software from our website. Our inside sales team handles lead qualifications as well as smaller transactions, while larger or more complex transactions are handled by our globally distributed direct field sales teams. Our sales engineers help define customer use cases and pre-sales qualification and evaluation.

        We maintain a distributor and reseller partner network, or channel, that often co-sells with our field sales organization, especially in EMEA and APAC. Our channel provides us with additional sales leverage by sourcing new prospects, providing technical support to existing customers, upselling for additional use cases and daily indexing capacities and maintenance renewals. This channel expands our geographic sales reach worldwide, particularly in key international markets such as the United Kingdom, Germany, Japan and China. As of January 31, 2013, we had over 350 channel partners

worldwide. Historically, the majority of EMEA and APAC sales have been fulfilled through channel partners and we expect this trend to continue for the near term.

        In addition to acquiring new customers, our sales teams are responsible for driving renewals of existing contracts as well as increased adoption of our software by existing customers. To accomplish this, our field and inside sales teams work closely with our customers to drive expanded licenses through higher capacity or upgrades and additional use cases within existing customers. Our field sales teams are organized geographically across the Americas, EMEA and APAC. We intend to invest in our international sales organization to drive greater market penetration in EMEA and APAC. We also have a dedicated sales team focused on government customers, which covers United States federal, state and local government entities. For fiscal 2013, 2012 and 2011, our revenues from our international operations represented 22%, 24% and 21% of total revenues, respectively. For additional information regarding our sales by geographic location, see Note 9 to our consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

        We focus our marketing efforts on increasing Splunk's brand and product awareness, driving viral adoption, communicating product advantages and business benefits and generating leads for our sales force and channel partners. We market our software as a targeted solution for specific use cases and as an enterprise solution for machine data. We engage with existing customers to provide community-based education and awareness and to promote expanded use of our software within these customers. We host Splunk Live! events across our sales regions to engage with both existing customers and new prospects as well as drive product training. We host an annual worldwide user and partner conference (.conf) as another way to support the Splunk community to foster collaboration and help our customers drive further business results from our software.

Research and Development

        We invest substantial resources in research and development to enhance our software, develop new end market specific solutions and apps, conduct software and quality assurance testing and improve our core technology. Our technical staff monitors and tests our software on a regular basis, and we maintain a regular release process to refine, update, and enhance our existing products.

        Research and development expense totaled $41.9 million, $23.6 million and $14.0 million for fiscal 2013, 2012 and 2011, respectively.

Intellectual Property

        We rely on patent, trademark, copyright and trade secret laws, confidentiality procedures and contractual provisions to protect our technology. The nature and extent of legal protection of our intellectual property rights depends on, among other things, its type and the jurisdiction in which it arises. We believe that our intellectual property rights are valuable and important to our business.

        We retain ownership of software we develop. All software is licensed to users and primarily provided in object code pursuant to either shrink-wrap, embedded or on-line licenses, or signed license agreements. These agreements generally contain restrictions on duplication, disclosure and transfer. We are currently unable to measure the full extent of unauthorized use, or piracy, of our software. We believe, however, that software piracy is and can be expected to be a persistent problem that negatively impacts our revenue and financial results.

        Nonetheless, our intellectual property rights may not be successfully asserted in the future or may be invalidated, circumvented or challenged. In addition, the laws of various foreign countries where our

12

Table of Contents

products are distributed do not protect our intellectual property rights to the same extent as United States laws. See Item 1A, "Risk Factors," for further discussion of risks related to intellectual property.

Customers

        Our customer base has grown from approximately 450 customers at the end of fiscal 2008 to over 5,200 Splunk Enterprise customers in more than 90 countries, including over 60 of the Fortune 100, as of January 31, 2013. Our customer count consists of organizations that have purchased our software; we exclude users of our trial software and Splunk Storm from our customer count. We provide products and services to customers of varying sizes, including enterprises, educational institutions and government agencies. At January 31, 2013, one customer represented greater than 10% of total accounts receivable. No individual customer represented more than 10% of our revenues in fiscal 2013, 2012 or 2011. Our current customer base spans numerous industry verticals, including cloud and online services; education; financial services; government; healthcare/pharmaceuticals; industrials/manufacturing; media/entertainment; retail/ecommerce; technology and telecommunications.

Competition

        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:

        The principal competitive factors in our markets are product features, performance and support, product scalability and flexibility, ease of deployment and use, total cost of ownership and time to value. We believe that we generally compete favorably on the basis of the foregoing factors. Our software contains a rich feature set starting with its powerful, intuitive search-engine interface and continuing with its ability to provide results to customized user queries in real time. We offer a broad range of support options, and our customers consistently provide us with high ratings for our support. Our software has the capability to collect and index data at massive scale and enables users to quickly and easily define customized searches and to correlate, analyze, monitor and report on their data. In addition, our software does not require long, costly deployment cycles typically associated with enterprise software. The ability to rapidly capture and analyze massive amounts of data results in a broad set of use cases for our software and enables our software to displace traditional enterprise software and discrete solutions providing IT operations management, security and compliance, and business intelligence. While we believe that our software provides a broad variety of use cases at a low

13

Table of Contents

total cost of ownership, we price our software licenses based upon estimated daily indexing capacity. Our pricing method may ultimately result in a higher total cost to users as data volumes increase over time, making it more difficult for us to compete in our markets.

        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. 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. Smaller companies could also launch new products and services that we do not offer and that could gain market acceptance quickly.

Employees

        As of January 31, 2013, our total headcount was 736 employees. None of our United States employees is represented by a labor union with respect to his or her employment with us. Employees in certain European countries have the benefits of collective bargaining arrangements at the national level. We have not experienced any work stoppages.

Item 1A.    Risk Factors

        Our operations and financial results are subject to various risks and uncertainties including those described below. 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 or others not specified below 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.

The market for our software licenses 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 licenses, 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 licenses. If the market for our software licenses 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 or information technology 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. We believe that these are inherent risks and difficulties 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:

15

Table of Contents

        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 business operations and financial 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. The timing and size of large transactions are often hard to predict in any particular period. For example, we completed a transaction during the quarter ended January 31, 2013 that exceeded $20 million, the largest in our history. 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 half 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 financial results to fluctuate from quarter to quarter include:

16

Table of Contents

        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 January 31, 2013, approximately 40% 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:

17

Table of Contents

        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 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, financial 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 $36.7 million, $11.0 million and $3.8 million in the fiscal years ended January 31, 2013, 2012 and 2011 respectively. As a result, we had an accumulated deficit of $90.7 million at January 31, 2013. Because the market for our software is rapidly evolving and has not yet reached widespread adoption, it is difficult for us to predict our future 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 as a newly public company, we have and will continue to 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 licenses, 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 achieve, sustain or increase profitability on a consistent basis, could cause the value of our common stock to decline.

Because we derive substantially all of our revenues and cash flows from sales of licenses of 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 sales of licenses of our Splunk Enterprise product. As such, the market acceptance of our software is critical to our continued success. Demand for licenses to 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 until August 2012, we did not offer a cloud-based service on a commercial basis and which currently represents a de minimis percentage of our overall revenue. 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 operations, financial results 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,

18

Table of Contents

open source initiatives and custom development efforts, which provide solutions in the specific markets we address. Our principal competitors include:

        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 operations, financial results and growth prospects. 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 license 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 operations and financial results could be materially and adversely affected.

19

Table of Contents

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 financial 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 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. Our growth creates additional challenges and risks with respect to attracting, integrating and retaining qualified employees, particularly sales personnel. 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 licensing 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 license, varies substantially from customer to customer. In addition, the introduction of Splunk Storm, our cloud-based service, has generated interest from our customers who are also considering purchasing and deploying Splunk Enterprise, our on-premise solution. In some cases, our customers wish to consider both products, potentially further slowing our sales cycle. Our sales cycle can extend to more than a year for certain customers, particularly 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 license. 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

20

Table of Contents

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, competitive offerings or alterations or reductions in our customers' spending levels. If our 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, operations, financial results 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 licenses 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 are 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 business operations and financial results.

        During the fiscal year ended January 31, 2013, we derived approximately 22% of our revenues 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

21

Table of Contents

we rely heavily on resellers for non-United States 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:

        Any of these risks could adversely affect our international operations, reduce our international revenues or increase our operating costs, adversely affecting our business operations, financial results 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 foreign government requirements and laws 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 United States regulations applicable to us. Although we have 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.

22

Table of Contents

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 operations and financial results.

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

        Our products are subject to United States 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 have taken a number of actions to prevent such violations from recurring and continue to review and make enhancements to our export compliance procedures that are designed to further strengthen compliance with the laws.

        Furthermore, our products are subject to United States export controls that prohibit the shipment of certain products and services without the required export authorizations or export to countries, governments, and persons targeted by United States sanctions. While we have taken precautions to prevent our products and services from being exported in violation of these laws, in certain instances we shipped our encryption products prior to obtaining the required export authorizations and certain of our products that are available at no cost have been downloaded by persons in countries that are the subject of United States embargoes. These exports were likely made in violation of United States export control and sanction laws. As a result, in March 2012, we filed Final Voluntary Self Disclosures with the United States Department of Commerce's Bureau of Industry and Security ("BIS"), and the United States Department of Treasury's Office of Foreign Assets Control ("OFAC"), concerning these potential violations. On July 3, 2012, OFAC notified us that it had completed its review of these matters and closed its review with the issuance of a Cautionary Letter, and on November 15, 2012, BIS notified us that it had completed its review of these matters and closed its review with the issuance of a Warning Letter. No monetary penalties were assessed against the Company by either OFAC or BIS.

        Based upon our internal review, we believe that we have not had any paying customers in countries sanctioned by the United States 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 United States 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 internal review, we believe that we do not have any paying or non-paying customers on any United States Government lists of prohibited persons. We have instituted a process for screening all paying and non-paying customers against United States Government lists of prohibited persons going forward.

        In the future, if we are found to be in violation of United States 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.

        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.

23

Table of Contents

        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 operations and financial results.

If we are unable to maintain successful relationships with our channel partners, our business operations, financial results and growth prospects 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 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 collectability 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 pricing and licensing challenges that could make it difficult for us to derive value from our customers.

        We generally charge our customers for their use of our Splunk Enterprise software based on their estimated peak daily indexing capacity. Our pricing method may ultimately result in a higher total cost to users as data volumes increase over time, making it more difficult for us to compete in our markets. As the amount of machine data within our customers' organizations grows, we may face downward pressure from our customers regarding our pricing, which could adversely affect our revenues and operating margins. In addition, our unique pricing model may allow competitors with different pricing models to attract customers unfamiliar or uncomfortable with our pricing model, which would cause us

24

Table of Contents

to lose business or modify our pricing model, both of 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. There is no guaranty that users of our software will abide by the terms of these encrypted keys. If this occurs, 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 our internal use 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 operations and financial 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 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. Further, our cloud-based service, Splunk Storm, is hosted exclusively by third parties. If any of 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 United States 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

25

Table of Contents

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 license 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 license to the paid version license of our software. Further, we depend on individuals within an organization who download the trial version license of our software being able to convince managers and decision-makers within their organization to convert to a paid version license 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 our software provide full functionality similar to our Splunk Enterprise product 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 Splunk Enterprise product through a SaaS model, in August 2012, we released Splunk Storm, our cloud-based service that provides a subset of our software's capabilities but is tailored for supporting machine data processing in the cloud. An exclusive 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 Splunk Enterprise product via a SaaS deployment, we would need to direct a significant portion of our capital investments to implement 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 for our Splunk Enterprise product. Moreover, sales of Splunk Storm or a potential future SaaS offering could cannibalize sales of our Splunk Enterprise software licenses. 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 operations and financial results.

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:

26

Table of Contents

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

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 United States federal, state and local governmental bodies, which affect how our channel partners and we 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 operations and financial results.

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

If our new software and software enhancements do not achieve sufficient market acceptance, our financial results 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

27

Table of Contents

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 financial 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:

        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 financial 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.

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 operations and financial results.

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:

        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 our community site called 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 our Splunkbase community website, 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 our Splunk Answers community site for support in connection with their use of our software. We do not review or test the information that non-Splunk employees post on our Splunk Answers community site to ensure its accuracy or efficacy in resolving technical issues. Therefore, we cannot ensure that all the information listed on our Splunk Answers community site is accurate or that it will not adversely affect the performance of our software. Furthermore, users who post such information on our Splunk Answers community site 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 our Splunk Answers community site, 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 and other jurisdictions outside 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

29

Table of Contents

rights, copyrights, trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Our issued patents and any patents issued in the future, may not provide us with any competitive advantages, 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 complex and often 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 "America Invents Act") and other national governments and from interpretations of the intellectual property laws of 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. We generally enter into confidentiality agreements with our employees, consultants, vendors and customers, and generally limit access to and distribution of our proprietary information. 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. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as the laws of the United States, and many foreign countries do not enforce these laws as diligently as government agencies and private parties in the United States. 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 operations or financial results.

30

Table of Contents

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. From time-to-time, third parties, including certain of these leading companies, have asserted and may assert patent, copyright, trademark or other intellectual property rights against us, our channel partners or our customers. 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 have in the past settled 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 operations and financial results.

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, we do not have the ability to monitor or review the content that customers of Splunk Enterprise store, and therefore, we have no direct control over the substance of that 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 financial results.

        We use third party technology and systems for a variety of reasons, including, without limitation, encryption and authentication technology, employee email, content delivery to customers, back-office support and other functions. Although we have developed systems and processes that are designed to protect customer information and prevent data loss and other security breaches, including systems and processes designed to reduce the impact of a security breach at a third party vendor, such measures cannot provide absolute security.

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 licenses of our software.

        Personal privacy has become a significant issue in the United States and in many other countries where we offer licenses of 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 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

32

Table of Contents

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 our Splunk Answers community site, 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. 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.

        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,

33

Table of Contents

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 or uncertainty, particularly in light of United States and European fiscal and budgetary challenges and concerns could adversely affect our business operations or financial results. 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 licenses 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 or geography. If the economic conditions of the general economy or industries in which we operate worsen from present levels, our business operations and financial results 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

34

Table of Contents

existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing 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 business operations and financial results.

        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:

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

If currency exchange rates fluctuate substantially in the future, our financial results, 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. Although most of our sales contracts are denominated in U.S. dollars, and therefore substantially all of our revenues are not subject to foreign currency risk, a

35

Table of Contents

strengthening of the U.S. dollar could increase the real cost of our software to our customers outside of the U.S., adversely affecting our business operations and financial results. We 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 United States 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 United States 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 United States 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 United States 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 United States 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. If our existing NOLs are subject to limitations arising from previous ownership changes, possibly including, but not limited to, our recent initial public offering, our ability to utilize NOLs could be 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 financial results.

        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 financial results.

Our international operations subject us to potentially adverse tax consequences.

        We generally conduct our international operations through wholly owned subsidiaries, branches and representative offices 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

36

Table of Contents

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 previously 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.

Our stock price has been volatile, may continue to be volatile and may decline regardless of our financial performance.

        The trading prices of the securities of technology companies have been highly volatile. The market price of our common stock has fluctuated and may continue to fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

37

Table of Contents

        In addition, the stock markets, and in particular the market on which our common stock is 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 financial 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 depends 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.

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, employees 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. As of January 31, 2013, we had outstanding approximately 101 million shares of our common stock.

        As of January 31, 2013, certain holders of our common stock have rights, subject to some conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for our stockholders or ourselves. We have also registered shares of common stock that we may issue under our employee equity incentive plans. These shares will be able to be sold freely in the public market upon issuance.

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

        As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of The NASDAQ Stock Market and other applicable securities rules and regulations. Compliance with these rules and regulations has increased our legal and financial compliance costs, made some activities more difficult, time-consuming or costly and increased and will continue to increase demand on our systems and resources, particularly after we are no longer an "emerging growth company." The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and 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

38

Table of Contents

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 regulatory and governing bodies provide new guidance. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We will continue 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.

        However, for as long as we remain an "emerging growth company" as defined in the Jumpstart our Business Startups Act of 2012, or the JOBS Act, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies" including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We may take advantage of these reporting exemptions until we are no longer an "emerging growth company."

        We will remain an "emerging growth company" for up to five years, although if the market value of our common stock that is held by non-affiliates exceeds $700 million as of any second fiscal quarter close, our revenues exceed $1 billion, or we issue more than $1 billion in non-convertible debt in a three year period, we would cease to be an "emerging growth company" as of the following fiscal year end.

        As a result of disclosure of information as a public company, our business and financial condition have 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 operations and financial 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 operations and financial results. These factors could also make it more difficult for us to attract and retain qualified employees, executive officers and members of our board of directors.

We are 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 our fiscal 2014, the first fiscal year beginning after the fiscal year of our initial public offering. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting and after we cease to be an "emerging growth company" a

39

Table of Contents

statement that our independent registered public accounting firm has issued an opinion on our internal control over financial reporting.

        We are in the 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, when required, our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls over financial reporting, 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 are an "emerging growth company" and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors potentially decreasing our stock price.

        We are an "emerging growth company," as defined in the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies" including, but not limited to, not being required to comply with the auditor attestation requirements of section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if potential investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile or decrease.

        In addition, Section 107 of the JOBS Act also provides that an "emerging growth company" can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an "emerging growth company" can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we have chosen to "opt out" of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

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, price appreciation of our common stock, which may never occur, may be the only way our stockholders 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 may have the effect of delaying or preventing a change of control or changes in our management. Our certificate of incorporation and bylaws include provisions that:

        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 have substantial ownership, which could delay or prevent a change in corporate control.

        As of January 31, 2013, our directors, executive officers and holders of more than 5% of our common stock, together with their affiliates, beneficially owned, in the aggregate, less than 40% of our outstanding common stock. As a result, these stockholders, acting together, have the ability to significantly influence 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, have the ability to significantly influence the management and affairs of our company. Accordingly, this concentration of ownership may adversely affect the market price of our common stock by:

        Our corporate headquarters occupy approximately 65,000 square feet in San Francisco, California under operating leases that expire in February 2019. As of January 31, 2013, we also lease approximately 11,000 square feet of office space in Cupertino, California to support our expanding business operations and hiring needs. As of January 31, 2013, we also lease smaller regional offices for sales, support and some product development in Seattle, Plano and Bethesda in the United States, and outside of the United States in Germany, Hong Kong, Singapore, United Kingdom, Taiwan, Sweden, Korea and France. While we believe our facilities are sufficient and suitable for the operations of our business today, we are in the process of adding new facilities and expanding our existing facilities as we add employees and expand into additional markets.

Stock Price and Dividends

        Our common stock, $0.001 par value, began trading on the NASDAQ Global Select Market on April 19, 2012, where its prices are quoted under the symbol "SPLK." As of January 31, 2013 there were 91 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

        The following table sets forth the reported high and low sales prices of our common stock for the periods indicated, as regularly quoted on the NASDAQ Global Select Market:

 
   High   Low

   $ 37.57   $ 25.15  

Third Quarter

   $ 39.75   $ 27.00  

Fourth Quarter

   $ 34.98   $ 26.10  

        We have never declared or paid, and do not anticipate declaring or paying in the foreseeable future, any cash dividends on our capital stock. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors, subject to applicable laws and will depend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects, and other factors our board of directors may deem relevant.

Use of Proceeds

        On April 24, 2012, we closed our initial public offering of 15,525,000 shares of common stock, which included 14,532,278 shares of common stock sold by us (inclusive of 2,025,000 shares of common stock from the full exercise of the overallotment option of shares granted to the underwriters) and 992,722 shares of common stock sold by the selling stockholders. The offer and sale of all of the shares in the initial public offering were registered under the Securities Act pursuant to a registration statement on Form S-1 (File No. 333-178988), which was declared effective by the SEC on April 18, 2012. Morgan Stanley, Credit Suisse, J.P. Morgan, BofA Merrill Lynch, UBS Investment Bank, Pacific Crest Securities and Cowen and Company acted as the underwriters. The public offering price of the shares sold in the offering was $17.00 per share. We did not receive any proceeds from the sales of shares by the selling stockholders. The total gross proceeds from the offering to us were $247.2 million. After deducting underwriting discounts and commissions of $17.3 million and offering expenses payable by us of $4.6 million, we received approximately $225.2 million. There has been no material change in the planned use of proceeds from our initial public offering as described in our final IPO prospectus filed with the SEC on April 20, 2012 pursuant to Rule 424(b) of the Securities Act. We invested the funds received in registered money market funds.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under "Risk Factors" included in Part I, Item 1a or in other parts of this report.

Overview

        Splunk provides an innovative software platform that enables organizations to gain real-time operational intelligence by harnessing the value of their data. Our software collects and indexes data at massive scale, regardless of format or source, and enables users to quickly and easily search, correlate, analyze, monitor and report on this data, all in real time. Our software addresses the risks, challenges and opportunities organizations face with increasingly large and diverse data sets, commonly referred to as big data, and is specifically tailored for machine-generated data. Machine data is produced by nearly every software application and electronic device in an organization and contains a definitive, time-stamped record of various activities, such as transactions, customer and user activities, and security threats. Our software is designed to help users in various roles, including IT and business professionals, quickly analyze their machine data and realize real-time visibility into and intelligence about their organization's operations. This operational intelligence enables organizations to improve service levels, reduce costs, mitigate security risks, demonstrate and maintain compliance and gain new insights that enable them to drive better business decisions.

        We believe the market for software that provides operational intelligence presents a substantial opportunity as data grows in volume and diversity, creating new risks, opportunities and challenges for organizations. Since our inception, we have invested a substantial amount of resources developing our products and technology to address this market, specifically with respect to machine data.

        Our software architecture is designed to accelerate return-on-investment for our customers. It does not require customization, long deployment cycles or extensive professional services commonly associated with traditional enterprise software applications. Users can simply download and install the software, typically in a matter of hours, connect to their relevant machine data sources and begin realizing operational intelligence. We also offer customers with complex IT infrastructure the ability to leverage the expertise of our professional services organization to deploy our software. We base our license fees on the estimated daily data indexing capacity our customers require. Prospective customers can download a trial version of our software that provides a full set of features but limited data

indexing capacity. Following the 60-day trial period, prospective customers can purchase a license for our product or continue using our product with reduced features and limited data indexing capacity. We primarily license our software under perpetual licenses whereby we generally recognize the license fee portion of these arrangements upfront. As a result, the timing of when we enter into large perpetual licenses may lead to fluctuations in our revenues and operating results because our expenses are largely fixed in the short-term.

        We intend to continue investing for long-term growth. We have invested and expect to continue to invest heavily in our product development efforts to deliver additional compelling features, address customer needs and enable solutions that can address new end markets. In addition, we expect to continue to aggressively expand our sales and marketing organizations to market and sell our software both in the United States and internationally.

        Our goal is to make our software the platform for delivering operational intelligence and real-time business insights from machine data. The key elements of our growth strategy are to:

        We believe the factors that will influence our ability to achieve our goals include, among other things, our ability to deliver additional functionality; drive acquisition of new customers across geographies and industries; cultivate incremental sales from our existing customers by driving increased use of our software within organizations; provide additional solutions that leverage our core machine data engine to help organizations understand and unlock the value of their machine data in specific end markets and use cases; add additional OEM and strategic relationships to enable new sales channels for our software as well as extend our integration with third party products; and help software developers leverage the functionality of our machine data engine through SDKs and APIs.

        On April 24, 2012, we closed our initial public offering ("IPO") whereby 15,525,000 shares of common stock were sold to the public (inclusive of 2,025,000 shares of common stock pursuant to the full exercise of an overallotment option granted to the underwriters and 992,722 shares of common stock sold by selling stockholders). The aggregate net proceeds from the offering were $225.2 million, net of underwriting discounts and commissions and offering expenses payable by us. On July 25, 2012, we closed our follow-on offering, in which certain of our stockholders sold 11,744,064 shares of common stock to the public. The aggregate offering price for shares sold in the offering was approximately $320.2 million, net of underwriting discounts and commissions. On August 1, 2012, the underwriters exercised in full their option to purchase 1,761,609 additional shares of common stock from our selling stockholders. We did not receive any proceeds from the sale of shares in the follow-on offering.

        For the fiscal years ended January 31, 2013, 2012 and 2011, our revenues were $198.9 million, $121.0 million and $66.2 million, respectively. For the fiscal year ended January 31, 2013, approximately 22% of our revenues were derived from customers located outside the United States. Our customers and end-users represent the public sector and a wide variety of industries, including financial services, manufacturing, retail and technology, among others. As of January 31, 2013, we had over 5,200 Splunk Enterprise customers, including over 60 of the Fortune 100.

        For the fiscal years ended January 31, 2013, 2012 and 2011, our GAAP operating loss was $22.0 million, $8.7 million and $3.3 million, respectively, and our non-GAAP operating loss was $1.4 million, $4.9 million and $1.7 million, respectively.

        For the fiscal years ended January 31, 2013, 2012 and 2011, our GAAP net loss was $36.7 million, $11.0 million and $3.8 million, respectively, and our non-GAAP net loss was $2.0 million, $5.2 million and $1.9 million, respectively.

        Our fiscal results reflect seasonality in the sale of our products and services. Historically, a pattern of increased license sales in the fourth fiscal quarter as a result of industry buying patterns has positively impacted sales activity in that period, which can result in lower sequential revenue in the first fiscal quarter. Our gross margins and operating losses have been affected by these historical trends because the majority of our expenses are relatively fixed in the short term. The majority of our expenses are personnel-related and include salaries, stock-based compensation, benefits and incentive-based compensation plan expenses. As a result, we have not experienced significant seasonal fluctuations in the timing of expenses from period to period.

Non-GAAP Financial Results

        To supplement Splunk's consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States ("GAAP"), Splunk provides investors with certain non-GAAP financial measures, including non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP operating margin, and non-GAAP income (loss) per share (collectively the "non-GAAP financial measures"). These non-GAAP financial measures exclude stock-based compensation expense, employer payroll tax expense related to employee stock plans, and the change in fair value of certain preferred stock warrants previously issued by Splunk. In addition, non-GAAP financial measures include free cash flow, which represents cash from operations less purchases of property and equipment. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. Splunk uses these non-GAAP financial measures for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. Splunk believes that these non-GAAP financial measures provide useful information about Splunk's operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. In addition, these non-GAAP financial measures facilitate comparisons to competitors' operating results.

        Splunk excludes stock-based compensation expense and employer payroll tax expense related to employee stock plans from its non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP operating margin and non-GAAP income (loss) per share. Splunk excludes share-based compensation expense because it is non-cash in nature, and excluding this expense provides meaningful supplemental information regarding Splunk's operational performance. In particular, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, Splunk believes that providing non-GAAP financial measures that exclude this expense allows investors the ability to make more meaningful comparisons between Splunk's operating results and those of other companies. Splunk excludes employer payroll tax

48

Table of Contents

expense related to employee stock plans in order for investors to see the full effect that excluding that share-based compensation expense had on Splunk's operating results. These expenses are tied to the exercise or vesting of underlying equity awards and the price of Splunk's common stock at the time of vesting or exercise, which may vary from period to period independent of the operating performance of Splunk's business. Splunk also excludes expense attributable to the change in fair value of certain preferred stock warrants from its non-GAAP financial measures because it is a non-recurring, non-cash expense. Accordingly, Splunk believes that excluding these expenses provides investors and management with greater visibility to the underlying performance of its business operations, facilitates comparison of its results with other periods, and may also facilitate comparison with the results of other companies in its industry. Splunk considers free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that can be used for strategic opportunities, including investing in its business, making strategic acquisitions, and strengthening its balance sheet.

        There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by Splunk's competitors, and exclude expenses that may have a material impact upon Splunk's reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in Splunk's business and an important part of the compensation provided to Splunk's employees. The non-GAAP financial measures are meant to supplement, and be viewed in conjunction with, GAAP financial measures.

Components of Operating Results

        License revenues.    License revenues reflect the revenues recognized from sales of licenses to new customers and additional licenses to existing customers. We are focused on acquiring new customers and increasing revenues from our existing customers as they realize the value of our software by indexing higher volumes of machine data and expanding the use of our software through additional use cases and broader deployment within their organizations. A majority of our license revenues consists of revenues from perpetual licenses, under which we generally recognize the license fee portion of the arrangement upfront, assuming all revenue recognition criteria are satisfied. Customers can also purchase term license agreements, under which we recognize the license fee ratably, on a straight-line basis, over the term of the license. Due to the differing revenue recognition policies applicable to

50

Table of Contents

perpetual and term licenses, shifts in the mix between perpetual and term licenses from quarter to quarter could produce substantial variation in revenues recognized even if our sales remain consistent. In addition, seasonal trends that contribute to increased sales activity in the fourth fiscal quarter often result in lower sequential revenue in the first fiscal quarter, and we expect this trend to continue. For further discussion of seasonality, cyclicality and quarterly trends, as well as the impact on our margins and results, see "Quarterly Results of Operations—Seasonality, Cyclicality and Quarterly Trends," below. Comparing our revenues 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.

        Maintenance and services revenues.    Maintenance and services revenues consist of revenues from maintenance agreements and, to a lesser extent, professional services and training. Typically, when purchasing a perpetual license, a customer also purchases one year of maintenance service for which we charge a percentage of the license fee. When a term license is purchased, maintenance service is typically bundled with the license for the term of the license period. Customers with maintenance agreements are entitled to receive support and unspecified upgrades and enhancements when and if they become available during the maintenance period. We recognize the revenues associated with maintenance agreements ratably, on a straight-line basis, over the associated maintenance period. In arrangements involving a term license, we recognize both the license and maintenance revenues over the license period. We have a professional services organization focused on helping some of our largest customers deploy our software in highly complex operational environments and train their personnel. We recognize the revenues associated with these professional services on a time and materials basis as we deliver the services or provide the training.

        Professional services and training revenues as a percentage of total revenues were 7% for fiscal 2013. We have experienced continued growth in our professional services revenues primarily due to the deployment of our software with some customers that have large, highly complex IT environments.

        We expect maintenance and services revenues to become a larger portion of our total revenues as our installed customer base grows.

        Cost of license revenues.    Cost of license revenues includes all direct costs to deliver our product, including salaries, benefits, stock-based compensation and related expenses such as employer taxes, allocated overhead for facilities and IT and amortization of acquired intangible assets. We recognize these expenses as they are incurred.

        Cost of maintenance and services revenues.    Cost of maintenance and services revenues includes salaries, benefits, stock-based compensation and related expenses such as employer taxes for our maintenance and services organization, allocated overhead for facilities and IT and consulting services. We recognize expenses related to our maintenance and services organization as they are incurred.

        Our operating expenses are classified into three categories: research and development, sales and marketing, and general and administrative. For each category, the largest component is personnel costs, which includes salaries, employee benefit costs, bonuses, commissions as applicable, stock-based compensation and related expenses such as employer taxes. Operating expenses also include allocated overhead costs for depreciation of equipment, facilities and IT. Allocated costs for facilities consist of leasehold improvements and rent. Our allocated costs for IT include personnel costs for our IT organization and costs associated with our IT infrastructure. Operating expenses are generally recognized as incurred.

51

Table of Contents

        Research and development.    Research and development expenses primarily consist of personnel and facility-related costs attributable to our research and development personnel. We have devoted our product development efforts primarily to enhancing the functionality and expanding the capabilities of our software. We expect that our research and development expenses will continue to increase as we increase our research and development headcount to further strengthen and enhance our software and invest in the development of our solutions and apps.

        Sales and marketing.    Sales and marketing expenses primarily consist of personnel and facility-related costs for our sales, marketing and business development personnel, commissions earned by our sales personnel, and the cost of marketing and business development programs. We expect that sales and marketing expenses will continue to increase as we continue to hire additional personnel and invest in marketing programs.

        General and administrative.    General and administrative expenses primarily consist of personnel and facility-related costs for our executive, finance, legal, human resources and administrative personnel, legal, accounting and other professional services fees, and other corporate expenses. We have recently incurred, and expect to continue to incur, additional expenses as we expand our operations, including higher legal, corporate insurance and accounting expenses, and the additional costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act and related regulations. We also expect that general and administrative expenses will continue to increase as we expand our operations internationally.

        Other income (expense), net consists primarily of the changes in the fair value of our preferred stock warrants, interest expense on our outstanding debt and interest income on our cash balances.

        Provision for income taxes consists of state and foreign income taxes. Because of our history of United States net operating losses, we have established a full valuation allowance against potential future benefits for deferred tax assets including loss carryforwards and research and development and other tax credits.

        Fiscal 2013 compared to fiscal 2012.    Total revenues increased $78.0 million primarily due to growth in license revenues. The increase in license revenues was primarily driven by increases in our total number of customers, sales to existing customers and an increase in the number of larger orders. For example, we had 467 and 282 orders greater than $100,000 for the fiscal year ended January 31, 2013 and 2012, respectively. Our total number of Splunk Enterprise customers increased from approximately 3,700 at January 31, 2012 to approximately 5,200 at January 31, 2013. The increase in maintenance and services revenues was due to increases in sales of maintenance agreements resulting from the growth of our installed customer base as well as sales of our professional services.

        Fiscal 2012 compared to fiscal 2011.    Total revenues increased $54.7 million primarily due to growth in license revenues. The increase in license revenues was primarily driven by increases in our total number of customers, sales to existing customers and an increase in the number of larger orders. For example, we had 282 and 151 orders greater than $100,000 in fiscal 2012 and 2011, respectively. Our total number of customers increased from approximately 2,300 in fiscal 2011 to approximately 3,700 in fiscal 2012. The increase in maintenance and services revenues was due to increases in sales of maintenance agreements resulting from the growth of our installed customer base as well as sales of our professional services. We also experienced an increase in the proportion of our total revenues derived from customers outside the United States, which represented 24% and 21% of our total revenues in fiscal 2012 and 2011, respectively.

        Fiscal 2013 compared to fiscal 2012.    Total cost of revenues increased $9.8 million due to the $10.0 million increase in cost of maintenance and services revenues, offset slightly by the decrease in cost of license revenue. The increase in cost of maintenance and services revenues of $10.0 million was primarily related to an increase of $4.7 million in salaries and benefits expense due to increased headcount and $5.3 million related to professional services expense, as we continue to invest in our professional services organization. Total gross margin decreased slightly, while license gross margin increased slightly and maintenance and services gross margin remained flat, due to revenue mix, with maintenance and services revenue representing a higher percentage of total revenues.

        Fiscal 2012 compared to fiscal 2011.    Total cost of revenues increased $4.9 million primarily due to the increase in cost of maintenance and services revenues. The increase in cost of maintenance and services revenues of $4.3 million was primarily related to an increase of $2.1 million in salaries and benefits expense due to increased headcount, $1.3 million related to professional services expense and $0.7 million related to facilities and other overhead costs. Total gross margin was flat, although maintenance and services gross margin increased 6.6 percentage points due to increased leverage resulting from the increase in maintenance and services revenues as well as an increase in maintenance revenues as a percentage of total maintenance and services revenues.

This percentage is calculated as a percentage of the associated revenues.

        Our quarterly results reflect seasonality in the sale of our products and services. Historically, a pattern of increased license sales in the fourth fiscal quarter as a result of industry buying patterns has positively impacted sales activity in that period, which can result in lower sequential revenue in the first fiscal quarter. We believe that third fiscal quarter revenues have been and could continue to be flat compared to second fiscal quarter revenues due to a seasonal slow down in customer orders during the late summer months as a result of summer vacations and holidays in the United States and elsewhere around the world. We expect this seasonality to continue in fiscal 2014 and beyond. Our gross margins and operating losses have been affected by these historical trends because the majority of our expenses are relatively fixed in the short term. The timing of revenues in relation to our expenses, much of which does not vary directly with revenues, has an impact on the cost of revenues, research and development expense, sales and marketing expense, and general and administrative expense as a percentage of revenues in each fiscal quarter during the year. The majority of our expenses are personnel-related and include salaries, stock-based compensation, benefits and incentive-based compensation plan expenses. As a result, we have not experienced significant seasonal fluctuations in the timing of expenses from period to period. Although these seasonal factors are common in the technology industry, historical patterns should not be considered a reliable indicator of our future sales activity or performance.

        As is typical in the software industry, we expect a significant portion of our product license orders to be received in the last month of each fiscal quarter. We typically ship products shortly after the receipt of an order. We may have backlog consisting of product license orders that have not shipped and maintenance, professional and training services that have not been billed and for which the services have not yet been performed. Historically, our backlog has varied from quarter to quarter and has been immaterial to our total revenues.

Cash provided by financing activities

     236,235     5,292     863  

        Since fiscal 2010 we have funded our operations primarily through cash generated from operations. At January 31, 2013, our cash and cash equivalents of $305.9 million were held for working capital purposes, a majority of which was invested in money market funds. We intend to increase our capital expenditures in fiscal 2014, consistent with the growth in our business and operations. We believe that our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced software and services offerings, and the continuing market acceptance of our products. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us if at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition could be adversely affected.

        For fiscal 2013, cash inflows from our operating activities were $46.6 million, which reflects our net loss of $36.7 million, adjusted by non-cash charges of $37.8 million consisting primarily of $19.5 million for stock-based compensation, $14.1 million for the change in valuation of preferred stock warrants and $4.7 million for depreciation and amortization. Additional sources of cash inflows were from changes in our working capital, including a $62.0 million increase in deferred revenue, a $12.0 million increase in accrued payroll and compensation, a $3.4 million increase in accrued expenses and other liabilities and a $0.2 million increase in accounts payable. These cash inflows were offset by cash outflows including a $29.5 million increase in accounts receivable due to increased sales and a $2.7 million related to an increase in prepaid expenses and other current assets.

        For fiscal 2012, cash inflows from our operating activities were $14.6 million, which reflects our net loss of $11.0 million, adjusted by non-cash charges of $8.2 million consisting primarily of $3.8 million for stock-based compensation, $2.0 million for the change in valuation of preferred stock warrants and $2.1 million for depreciation and amortization. Additional sources of cash inflows were from changes in our working capital, including a $30.4 million increase in deferred revenue, a $11.1 million increase in accrued compensation and accrued expenses and other liabilities, primarily due to increased headcount,

partially offset by a $20.3 million increase in accounts receivable, due to increased sales, and a $3.5 million increase in prepaid expenses and other current and non-current assets.

        For fiscal 2011, we generated $8.4 million of cash inflows from our operating activities, which reflects our net loss of $3.8 million, adjusted by non-cash charges of $3.4 million consisting primarily of $1.6 million for stock-based compensation and $1.0 million for depreciation and amortization. Cash inflows included an increase of $11.0 million in deferred revenues, a $6.2 million increase in accrued compensation and accrued expenses and other liabilities, and a $0.5 million increase in accounts payable due to the timing of payments, primarily due to an increase in headcount, partially offset by an $8.0 million increase in accounts receivable associated with increased sales, and a $0.9 million increase in prepaid expenses and other current assets.

        Our investing activities consist primarily of capital expenditures to purchase property and equipment, sales of short-term investments and changes in our restricted cash. In the future, we expect to continue to invest in capital expenditures to support our expanding operations.

        During fiscal 2013, 2012 and 2011, cash used in investing activities was primarily attributable to capital expenditures for technology hardware to support the growth of our business, as well as leasehold improvements on our corporate and international offices.

        For fiscal 2013, cash provided by financing activities of $236.2 million consisted primarily of initial public offering proceeds of $225.2 million, net of paid underwriter discount and issuance costs, $6.9 million from exercises of stock options and $5.3 million from proceeds received from our employee stock purchase plan. These increases were partially offset by $2.3 million related to the repayment of a term loan.

        For fiscal 2012, cash provided by financing activities of $5.3 million consisted primarily of $3.0 million of proceeds from a term loan and $3.1 million from exercises of stock options, offset by $0.7 million related to the repayment of a term loan.

        For fiscal 2011, cash provided by financing activities of $0.9 million consisted primarily of $1.0 million from exercises of stock options, offset by $0.1 million related to the repayment of a financing obligation under sale leaseback.

        In May 2009, we entered into a Loan and Security Agreement with Silicon Valley Bank, which was most recently amended in March 2013. As amended, the agreement includes a revolving line of credit facility as described below. The agreement contains financial covenants and other customary affirmative and negative covenants. We were in compliance with all covenants as of January 31, 2013. As part of the agreement, we granted the lender a security interest in our personal property, excluding intellectual property and other intangible assets.

        We are able to borrow up to $10.0 million under the revolving line of credit facility, subject to a borrowing base determined on eligible accounts receivable and subject to a total maximum outstanding of $10.0 million. As of January 31, 2013 and 2012, we had $0 and $2.3 million outstanding on the revolving line of credit, respectively. Interest on any drawdown under the revolving line of credit accrues at the prime rate (3.25% in January 2013).

We entered into a sublease agreement on November 16, 2012 for a portion of our office space in the United Kingdom, and the future sublease rental income of $1.3 million has been included as an offset to our future minimum rental payments.

Off-Balance Sheet Arrangements

        During fiscal 2013, 2012 and 2011, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities, that have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Indemnification Arrangements

        During the ordinary course of business, we may indemnify, hold harmless and agree to reimburse for losses suffered or incurred, our customers, vendors and their affiliates for certain intellectual property infringement and other claims by third parties with respect to our products and services, in connection with our commercial end-user license arrangements or related to general business dealings with those parties.

        As permitted under Delaware law, we have entered into indemnification agreements with our officers and directors, indemnifying them for certain events or occurrences while they serve as officers or directors of the company.

        To date, there have not been any costs incurred in connection with such indemnification obligations; therefore, there is no accrual of such amounts at January 31, 2013. We are unable to estimate the maximum potential impact of these indemnifications on our future results of operations.

Critical Accounting Policies and Estimates

        We prepare our consolidated financial statements in accordance with generally accepted accounting principles in the United States. The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

        We believe that the assumptions and estimates associated with revenue recognition, share-based compensation and income taxes have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates. Accordingly, we believe these are the most critical to fully understand and evaluate our financial condition and results of operations.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk

        We are exposed to financial market risks, primarily changes in interest rates.

Interest Rate Risk

        We had cash and cash equivalents of $305.9 million as of January 31, 2013. We hold our cash and cash equivalents for working capital purposes. Our cash and cash equivalents are held in cash deposits and money market funds. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income.

        The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. This objective is accomplished by making diversified investments, consisting only of investment grade securities. During the fiscal years ended January 31, 2013 and 2012, the effect of a hypothetical 10% increase or decrease in overall interest rates would not have had a material impact on our interest income.

        Any draws under our revolving credit facility bear interest at a variable rate tied to the prime rate. As of January 31, 2013, the term loan facility was paid in full.

Foreign Currency Exchange Risk

        Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. All of our revenues are generated in U.S. dollars. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States and to a lesser extent in Europe and Asia. Our results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. The effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have a material impact on our historical consolidated financial statements. To date, we have not engaged in any hedging strategies. As our international operations grow, we will continue to reassess our approach to manage our risk relating to fluctuations in currency rates.

Inflation

        We do not believe that inflation had a material effect on our business, financial condition or results of operations in the last three fiscal years. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Splunk Inc.:

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, comprehensive loss, convertible preferred stock and stockholders' equity (deficit) and cash flows present fairly, in all material respects, the financial position of Splunk Inc. and its subsidiaries at January 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended January 31, 2013 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Description of the Business and Significant Accounting Policies

Business

        Splunk Inc. ("we", "us", "our") provides an innovative software platform that enables organizations to gain real-time operational intelligence by harnessing the value of their data. Our software collects and indexes data regardless of format or source, and enables users to search, correlate, analyze, monitor and report on this data. Our software addresses large and diverse data sets, commonly referred to as big data, and is specifically tailored for machine-generated data. Machine data is produced by nearly every software application and electronic device in an organization and contains a definitive, time-stamped record of various activities, such as transactions, customer and user activities, and security threats. Our software is designed to help users in various roles, including IT and business professionals, analyze machine data and realize real-time visibility into and intelligence about their organization's operations. This operational intelligence enables organizations to improve service levels, reduce costs, mitigate security risks, demonstrate and maintain compliance, and gain new insights that enable them to drive better business decisions. Splunk was incorporated in California in October 2003 and was reincorporated in Delaware in May 2006.

Fiscal Year

        The Company's fiscal year ends on January 31. References to fiscal 2013, for example, refer to the fiscal year ended January 31, 2013.

Initial Public Offering

        On April 24, 2012, we closed our initial public offering ("IPO") whereby 15,525,000 shares of common stock were sold to the public (inclusive of 2,025,000 shares of common stock pursuant to the full exercise of an overallotment option granted to the underwriters and 992,722 shares of common stock sold by selling stockholders). The aggregate net proceeds received by us from the offering were $225.2 million, net of underwriting discounts and commissions and offering expenses payable by us. Upon the closing of the IPO, all shares of our outstanding convertible preferred stock automatically converted into 56,930,194 shares of common stock, and outstanding warrants to purchase convertible preferred stock automatically converted into warrants to purchase 469,557 shares of common stock.

Follow-on Offering

        On July 25, 2012, we closed our follow-on offering, in which certain of our stockholders offered 11,744,064 shares of common stock at a price to the public of $28.25 per share. The aggregate offering price for shares sold in the offering was approximately $320.2 million, net of underwriting discounts and commissions. On August 1, 2012, the underwriters exercised in full their option to purchase 1,761,609 additional shares of common stock from our selling stockholders. We did not receive any proceeds from the sale of shares in this offering.

Use of Estimates

        The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting periods covered by the financial statements and accompanying notes. In particular, we make estimates with respect to the fair value of multiple elements in revenue recognition, uncollectible accounts

receivable, stock-based compensation, income taxes and contingencies. Actual results could differ from those estimates.

Segments

        We operate our business as one operating segment: the development and marketing of a software platform that enables our customers to gain real-time operational intelligence by harnessing the value of their data. Our chief operating decision maker is our Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Principles of Consolidation

        The accompanying consolidated financial statements include the accounts of Splunk Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.

Foreign Currency

        The functional currency of our foreign subsidiaries is the respective local currency. Translation adjustments arising from the use of differing exchange rates from period to period are included in Accumulated Other Comprehensive Income (loss) within Stockholders' Equity (deficit). Foreign currency transaction gains and losses are included in Other Income (Expense), Net and were not material for the three years ended January 31, 2013. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average exchange rate during the period. Equity transactions are translated using historical exchange rates.

Revenue Recognition

        We generate revenues primarily in the form of software license fees and related maintenance and services fees. License fees include perpetual license fees, term license fees and royalties. Maintenance and services primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available), training and professional services that are not essential to functionality.

        We recognize revenues when all of the following conditions are met:

        Signed agreements are used as evidence of an arrangement. If a contract signed by the customer does not exist, we use a purchase order as evidence of an arrangement. In cases where both a signed contract and a purchase order exist, we consider the signed contract to be the final persuasive evidence of an arrangement. Electronic delivery occurs when we provide the customer with access to the software via a license key. We assess whether a fee is fixed or determinable at the outset of the

71

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(1) Description of the Business and Significant Accounting Policies (Continued)

arrangement, primarily based on the payment terms associated with the transaction. We do not generally offer extended payment terms with typical terms of payment due between 30 and 60 days from delivery of software. We assess collectability of the fee based on a number of factors such as collection history and creditworthiness of the customer. If we determine that collectability is not probable, revenue is deferred until collectability becomes probable, generally upon receipt of cash.

        When contracts contain multiple elements wherein vendor specific objective evidence ("VSOE") exists for all undelivered elements and the services, if any, are not essential to the functionality of the delivered elements, we account for the delivered elements in accordance with the "Residual Method." Perpetual license arrangements are typically accompanied by maintenance agreements. Maintenance revenues consist of fees for providing software updates on a when and if available basis and technical support for software products ("post-contract support" or "PCS") for an initial term. Maintenance revenues are recognized ratably over the term of the agreement. We have established fair value for maintenance on perpetual licenses due to consistently priced standalone sales of maintenance. Revenues related to term license fees are recognized ratably over the contract term beginning on the date the customer has access to the software license key and continuing through the end of the contract term. In these cases we do not have VSOE of fair value for maintenance as fees for support and maintenance are bundled with the license over the entire term of the contract.

        License arrangements may also include professional services and training services, which are typically delivered early in the contract term. In determining whether professional services revenues should be accounted for separately from license revenues, we evaluate whether the professional services are considered essential to the functionality of the software using factors such as the nature of our software products; whether they are ready for use by the customer upon receipt; the nature of our implementation services, which typically do not involve significant customization to or development of the underlying software code; the availability of services from other vendors; whether the timing of payments for license revenues is coincident with performance of services; and whether milestones or acceptance criteria exist that affect the realizability of the software license fee. Substantially all of our professional services arrangements are billed on a time and materials basis and, accordingly, are recognized as the services are performed. Training revenues are recognized as training services are delivered. VSOE of fair value of professional and training services is based upon stand-alone sales of those services. Payments received in advance of services performed are deferred and recognized when the related services are performed.

        We are unable to establish VSOE of fair value for all undelivered elements in certain arrangements that include term licenses, maintenance and services, due to the lack of VSOE for maintenance bundled with the term license. In these instances, all revenue is recognized ratably over the period that the services are expected to be performed. In arrangements where the expected service periods of maintenance services and professional or training services differ, we recognize all revenue over the longer of the expected service periods, which is generally the maintenance period.

        We do not offer credits or refunds and therefore have not recorded any sales return allowance for any of the periods presented. Upon a periodic review of outstanding accounts receivable, amounts that are deemed to be uncollectible are written off against the allowance for doubtful accounts. Our policy is to record revenues net of any applicable sales, use or excise taxes.

        We recognize revenues from the indirect sales channel upon sell-through by the partner or distributor. Sell-through is determined when we receive an order form from a reseller for a specific end-user sale. We do not offer right of return, product rotation or price protection to any of our

72

channel partners. We also have licensing arrangements with OEM customers for which royalty fees are generally recognized as revenue upon receipt of reports of units shipped, respectively. Provided all other revenue criteria are met, the upfront, minimum, non-refundable license fees from OEM customers are recognized upon delivery, and on-going royalty fees are recognized upon reports of units shipped.

        In our consolidated statements of operations, revenues are categorized as license or maintenance and services revenues. We allocate revenues from arrangements containing multiple elements to each of these categories based on the VSOE of fair value for elements in each revenue arrangement and the application of the residual method for arrangements in which we have established VSOE of fair value for all undelivered elements. In arrangements where we are not able to establish VSOE of fair value for all undelivered elements, we first allocate revenues to any undelivered elements for which VSOE of fair value has been established, then allocate revenues to any undelivered elements for which VSOE of fair value has not been established based upon management's best estimate of fair value of those undelivered elements and apply a residual method to determine the license fee. Management's best estimate of fair value of undelivered elements for which VSOE of fair value has not been established is based upon the VSOE of similar offerings and other objective criteria.

        Deferred revenue consists substantially of amounts invoiced in advance of revenue recognition for our products and services described above. We recognize deferred revenue as revenue only when the revenue recognition criteria are met.

Cash and Cash Equivalents and Restricted Cash

        We consider all highly liquid instruments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. We do not hold or issue financial instruments for trading purposes. As of January 31, 2013, 2012 and 2011, $250.8 million, $19.5 million and $13.1 million, respectively, of cash and cash equivalents were invested in money market funds.

        Pursuant to the office lease agreement for our San Francisco office originally entered into in March 2008, we were originally required to maintain a minimum of $1.3 million in a letter of credit to the landlord for the security of the lease agreement. This amount was reduced to zero over the term of the lease during fiscal 2013. At January 31, 2013, 2012 and 2011, we had $0, $0.6 million and $0.8 million, respectively, of restricted cash satisfying the required amounts, which was held in a money market account. At January 31, 2013, 2012 and 2011, the current portion was $0, $0.1 million and $0.2 million and the noncurrent portion was $0, $0.5 million and $0.6 million, which amounts were included on the consolidated balance sheet in Prepaid expenses and other current assets and Other assets, respectively.

Concentration of Risk

        Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. We maintain the majority of our cash balance at one financial institution that management believes is a high-credit, quality financial institution and invest our cash equivalents in highly rated money market funds.

73

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(1) Description of the Business and Significant Accounting Policies (Continued)

        At January 31, 2013, there was one customer that represented approximately 31% of total accounts receivable. At January 31, 2012, there was one customer that represented approximately 17% of total accounts receivable.

        Our accounts receivable is subject to collection risks. Our gross accounts receivable is reduced for this risk by an allowance for doubtful accounts. This allowance is for estimated losses resulting from the inability of our customers to make required payments. It is an estimate and is regularly evaluated for adequacy by taking into consideration a combination of factors. We look at factors such as past collection experience, credit quality of the customer, age of the receivable balance, and current economic conditions. These factors are reviewed to determine whether an allowance for bad debts should be recorded to reduce the receivable balance to the amount believed to be collectible.

        The following table presents the changes in the allowance for doubtful accounts (in thousands):

 
   Fiscal Year Ended January 31,  
(in thousands)

   $ 821   $ 557   $ 400  
               

Fair Value of Financial Instruments

        The carrying amounts of certain of our financial instruments including cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short-term maturities. Based on borrowing rates currently available to us for financing obligations with similar terms and considering our credit risks, the carrying value of the financing obligation approximates fair value.

        Assets and liabilities recorded at fair value in the financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows:

        Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and considers factors specific to the asset or liability. Our convertible preferred stock warrant liability was classified within Level 3 of the fair value hierarchy.

Impairment of Long-Lived Assets

        We evaluate the recoverability of our long-lived assets including amortizable intangible and tangible assets. Acquired intangible assets are amortized over their useful lives. We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. We recognize such impairment in the event the net book value of such assets exceeds their fair value. If the fair value of the long-lived assets exceeds the carrying value of the net assets assigned, then the assets are not impaired and no further testing is performed. If the carrying value of the net assets assigned exceeds the fair value of the assets, then we must perform the second step of the impairment test in order to determine the implied fair value. No impairment of long-lived assets has occurred in the fiscal periods presented.

Property and Equipment

        Property and equipment are stated at cost net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets ranging from generally three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the Consolidated Statements of Operations. Maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense in the period incurred.

        The following table presents the estimated useful lives of our property and equipment:

 
   Useful Life

Computer equipment and software

   3 years

Furniture and fixtures

   5 years

Leasehold improvements

   Shorter of the useful life of the asset or the lease term

Capitalized Software Development Costs

        Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins upon the establishment of technological feasibility, which is generally the completion of a working prototype that has been certified as having no critical bugs and is a release candidate. Amortization begins once the software is ready for its intended use, generally based on the pattern in which the economic benefits will be consumed. We did not capitalize any internal software development costs for fiscal 2013 and 2012 because the cost incurred and the time between technological feasibility and product release was insignificant. For fiscal 2013, 2012 and 2011, total amortization expense was $118,000, $334,000 and $48,000 respectively, from capitalized purchased technology of $0.5 million in December 2010.

        Costs related to software acquired, developed or modified solely to meet our internal requirements, with no substantive plans to market such software at the time of development, are capitalized. Costs incurred during the preliminary planning and evaluation stage of the project and during post implementation operational stage are expensed as incurred. Costs incurred during the application development stage of the project are capitalized. We define the design, configuration, and coding process as the application development stage. For fiscal 2013 and 2012, we capitalized $2.8 million and $1.6 million of costs related to computer software developed for internal use, which is

75

included in Property and Equipment on the Consolidated Balance Sheets, respectively. During fiscal 2013, $278,000 of these costs were amortized.

        As of January 31, 2013, expected future amortization for capitalized computer software costs developed for internal use is as follows:

Fiscal years:

  $ 2,498,000  
       

Commissions

        Commissions are recorded as a component of sales and marketing expenses and consist of the variable compensation paid to our sales force. Sales commissions are earned and recorded at the time that a customer has entered into a binding purchase agreement. Commissions paid to sales personnel are recoverable only in the case that we cannot collect the invoiced amounts associated with a sales order. Commission expense was $26.9 million, $22.3 million and $9.9 million for fiscal 2013, 2012 and 2011 respectively.

Leases

        We lease our facilities under operating leases. For leases that contain rent escalation or rent concession provisions, we record the total rent expense during the lease term on a straight-line basis over the term of the lease. We record the difference between the rent paid and the straight-line rent expense as a current and non-current deferred rent liability in Accrued expenses and other liabilities and Other liabilities, non-current, respectively, in the accompanying Consolidated Balance Sheets. Rent expense was $3.9 million, $2.6 million and $1.6 million during fiscal 2013, 2012 and 2011, respectively.

Advertising Expense

        We expense advertising costs as incurred. We incurred $6.0 million, $3.7 million and $2.0 million in advertising expenses for fiscal 2013, 2012 and 2011, respectively. Advertising costs are recorded in Sales and marketing expenses within the accompanying Consolidated Statements of Operations.

Stock-Based Compensation

        We recognize compensation expense for all share-based payment awards, including stock options and restricted stock, based on the estimated fair value of the award on the grant date in the Consolidated Statements of Operations over the related vesting periods. The expense recorded is based on awards ultimately expected to vest and therefore is reduced by estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We calculate the fair value of options using the Black-Scholes method and expense using the straight-line attribution approach.

(1) Description of the Business and Significant Accounting Policies (Continued)

        We account for equity awards issued to non-employees, such as consultants, in accordance with the guidance relating to equity instruments that are issued to other than employees for acquiring, or in conjunction with selling, goods or services, using the Black-Scholes method to determine the fair value of such instruments. Awards granted to non-employees are remeasured over the vesting period, and the resulting value is recorded as an expense over the period the services are received.

        The fair value of each option grant and stock purchase right granted under the Employee Stock Purchase Plan ("ESPP") was estimated on the date of grant using the Black-Scholes option pricing model. We recognize stock-based expenses related to our ESPP on a straight-line basis over the offering period, which is twelve months. Stock-based expenses are recognized net of estimated forfeiture activity.

        The determination of the grant date fair value of options using an option-pricing model is affected by assumptions regarding a number of other complex and subjective variables, which include our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends.

Income Taxes

        Income taxes are accounted for under the asset and liability method in accordance with authoritative guidance for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

        We adopted the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes, on February 1, 2009. There was no impact upon adoption of ASC 740-10 as our liability recognized under previous accounting guidance was consistent with that required under the new guidance. We have adopted the accounting policy that interest expense and penalties relating to income tax positions are classified within the provision for income taxes.

Recently Issued Accounting Pronouncements

        On June 16, 2011, the FASB issued new authoritative guidance on comprehensive income (loss) that eliminates the option to present the components of other comprehensive income (loss) as part of the statement of shareholders' equity. Instead, we must report comprehensive income (loss) in either a single continuous statement of comprehensive income (loss), which contains two sections, net income and other comprehensive income (loss), or in two separate but consecutive statements. We adopted this authoritative guidance in our first fiscal quarter ended April 30, 2012 by including a new separate consolidated statement of comprehensive loss.

(2) Fair Value Measurements

        The carrying amounts of certain of our financial instruments including cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short-term maturities. Based on borrowing rates currently available to us for financing obligations with similar

terms and considering our credit risks, the carrying value of the financing obligation approximates fair value.

        Assets and liabilities recorded at fair value in the financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels that are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows:

        Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

        The following table sets forth the fair value of our financial assets and liabilities that were measured on a recurring basis as of January 31, 2013 and 2012 (in thousands):

        Our investments in money market funds are measured at fair value on a recurring basis. Our money market funds are targeted to be priced and have a net asset value of $1 per share. These money market funds are actively traded and reported daily through a variety of sources. The fair value of the money market fund investments are classified as Level 1.

        During the fiscal year ended January 31, 2013, we did not remeasure any nonfinancial assets and liabilities measured at fair value on a nonrecurring basis, such as intangible assets, and property and equipment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Fair Value Measurements (Continued)

        Prior to the closing of our IPO on April 24, 2012, our preferred stock warrants were categorized as Level 3 because they were valued based on unobservable inputs and management's judgment due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. These assumptions are inherently subjective and involve significant management judgment.

        We performed a fair value assessment of the preferred stock warrant inputs at January 31, 2012. The fair value of the preferred stock warrant liability was estimated using the Black-Scholes pricing model. We performed the final remeasurement of the warrants at the closing date of our IPO. See Note 7 for further information.

(3) Property and Equipment

        Property and equipment are stated at cost, net of accumulated depreciation and amortization. These assets are depreciated and amortized using the straight-line method over their estimated useful lives. Property and equipment consisted of the following (in thousands):

 
   As of January 31,  
 
   2013   2012  

Computer equipment and software

   $ 16,077   $ 10,712

     (9,715 )   (5,660 )
           

Property and equipment, net

   $ 13,205   $ 8,919  
           

        Depreciation and amortization expense was $4.7 million, $2.1 million and $1.0 million for the fiscal years ended January 31, 2013, 2012 and 2011 respectively.

(4) Commitments and Contingencies

        In September 2008, we entered into a purchase and sale agreement to sell equipment totaling $0.5 million and leaseback the same equipment over a period of 36 months. We had the option to purchase all, but not less than all, of the equipment for a mutually agreed upon market value plus taxes applicable at the end of the lease. Due to our continuing involvement in certain aspects of this equipment, the sale and leaseback of this equipment does not qualify as a sale-leaseback under United States generally accepted accounting principles, but rather accounted for as a financing of the equipment. We recorded a financing obligation liability totaling $0.5 million in December 2008. Payments under the financing were made monthly through December 31, 2011 at an interest rate of 8% per annum. At January 31, 2013, we had no payments remaining under the financing.

        We lease our office spaces under non-cancelable operating leases with rent expense recognized on a straight-line basis over the lease term. Rent expense was $3.9 million, $2.6 million and $1.6 million

We entered into a sublease agreement on November 16, 2012 for a portion of our office space in the United Kingdom, and the future sublease rental income of $1.3 million has been included as an offset to our future minimum rental payments.

        We are subject to certain routine legal proceedings, as well as demands and claims that arise in the normal course of our business. We make a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter. In our opinion, resolution of any pending claims (either individually or in the aggregate) is not expected to have a material adverse impact on our consolidated results of operations, cash flows or financial position, nor is it possible to provide an estimated amount of any such loss. However, depending on the nature and timing of any such dispute, an unfavorable resolution of a matter could materially affect our future results of operations or cash flows, or both, in a particular quarter.

        During the ordinary course of business, we may indemnify, hold harmless and agree to reimburse for losses suffered or incurred, our customers, vendors and their affiliates for certain intellectual property infringement and other claims by third parties with respect to our products and services, in connection with our commercial end-user license arrangements or related to general business dealings with those parties.

        As permitted under Delaware law, we have entered into indemnification agreements with our officers and directors, indemnifying them for certain events or occurrences while they serve as officers or directors of the company.

        To date, there have not been any costs incurred in connection with such indemnification obligations; therefore, there is no accrual of such amounts at January 31, 2013. We are unable to estimate the maximum potential impact of these indemnifications on our future results of operations.

        Our products are subject to United States export controls that prohibit the shipment of certain products and services without the required export authorizations or export to countries, governments, and persons targeted by United States sanctions. While we have taken precautions to prevent our products and services from being exported in violation of these laws, in certain instances we shipped our encryption products prior to obtaining the required export authorizations and certain of our

products that are available at no cost have been downloaded by persons in countries that are the subject of United States embargoes. These exports were likely made in violation of United States export control and sanction laws. As a result, in March 2012, we filed Final Voluntary Self Disclosures with the United States Department of Commerce's Bureau of Industry and Security ("BIS"), and the United States Department of Treasury's Office of Foreign Assets Control ("OFAC"), concerning these potential violations. On July 3, 2012, OFAC notified us that it had completed its review of these matters and closed its review with the issuance of a Cautionary Letter, and on November 15, 2012, BIS notified us that it had completed its review of these matters and closed its review with the issuance of a Warning Letter. No monetary penalties were assessed against the Company by either OFAC or BIS.

(5) Debt Financing Facilities

        In May 2009, we entered into a Loan and Security Agreement with Silicon Valley Bank, which was most recently amended in March 2013. As amended, the agreement includes a revolving line of credit facility as described below. The agreement contains financial covenants and other customary affirmative and negative covenants. We were in compliance with all covenants as of January 31, 2013. As part of the agreement, we granted the lender a security interest in our personal property, excluding intellectual property and other intangible assets.

        We are able to borrow up to $10.0 million under the revolving line of credit facility, subject to a borrowing base determined on eligible accounts receivable and subject to a total maximum outstanding of $10.0 million. As of January 31, 2013 and 2012, we had $0 and $2.3 million outstanding on the revolving line of credit, respectively. Interest on any drawdown under the revolving line of credit accrues at the prime rate (3.25% in January 2013).

(6) Common Stock

        Our certificate of incorporation, as amended and restated, authorizes us to issue 1,000,000,000 shares of common stock, $0.001 par value per share. At January 31, 2013 and January 31, 2012, 100,920,350 shares and 23,092,407 shares of common stock were issued and outstanding, respectively.

        Stock options granted under our stock option plan provide certain employee option holders the right to exercise unvested options for shares of restricted common stock. Shares of restricted common stock, in the amounts of 93,750 and 411,318 at January 31, 2013 and January 31, 2012, respectively, were subject to a repurchase right held by us at the original issuance price in the event the optionees' employment is terminated either voluntarily or involuntarily. For early exercises of employee options, this repurchase right generally lapses as to 1/4th of the shares subject to the option on the first anniversary of the vesting start date and as to 1/48th of the shares monthly thereafter.

        These repurchase terms are considered to be a forfeiture provision and do not result in variable accounting. The restricted shares issued upon early exercise of stock options are legally issued and outstanding. However, these restricted shares are only deemed outstanding for basic earnings per share computation purposes upon the respective repurchase rights lapsing. We treat cash received from employees for the exercise of unvested options as a refundable deposit shown as a liability in our consolidated balance sheets.

(7) Convertible Preferred Stock

        Upon the closing of our IPO, all outstanding shares of convertible preferred stock were converted into shares of common stock. Warrants to purchase convertible preferred stock were converted into warrants to purchase common stock.

        Prior to the closing of our IPO, we remeasured the fair value of the preferred stock warrants at each balance sheet date. The fair value of the outstanding warrants was classified within non-current liabilities on the consolidated balance sheets, and any changes in fair value were recognized as a component of Other income (expense), net in our consolidated statements of operations. We performed the final remeasurement of the warrants at the closing date of our IPO and recorded an expense of $14.1 million arising from the revaluation during the three months ended April 30, 2012. The fair value of the outstanding warrants was determined using the Black-Scholes option-pricing model. We determined the fair value of each warrant on the issuance date and subsequent reporting dates using the Black-Scholes pricing model utilizing the assumptions noted below. The expected term of the warrant is based on the remaining contractual expiration period. The expected stock price volatility for our stock was determined by examining the historical volatilities of a group of our industry peers as we did not have any trading history of our common stock. The risk-free interest rate was calculated using the average of the published interest rates for United States Treasury zero-coupon issues with maturities that approximate the expected term. The dividend yield assumption is zero as we did not have any history of, nor plans for, dividend payments.

        The following assumptions were used to estimate the value of the preferred stock warrants during the fiscal years ended January 31, 2013 and 2012, respectively:

 
   Fiscal Year Ended

(8) Stock Compensation Plans

        In November 2003, our board adopted the 2003 Equity Incentive Plan (the "2003 Plan"). The 2003 Plan authorizes the granting of common stock options and restricted stock awards to employees, directors and consultants.

        In January 2012, our board approved the 2012 Equity Incentive Plan (the "2012 Plan"), which became effective upon the effectiveness of our IPO registration statement on Form S-1, on April 18,

2012. The 2012 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Code, to our employees and any parent and subsidiary corporations' employees, and for the grant of nonstatutory stock options, restricted stock, restricted stock units ("RSUs"), stock appreciation rights, performance units and performance shares to our employees, directors and consultants and any parent or subsidiary corporations' employees and consultants. Upon the effectiveness of our IPO registration statement on Form S-1, all shares that were reserved but not issued under the 2003 Plan became available for issuance under the 2012 Plan and no further shares will be granted pursuant to the 2003 Plan. Canceled or forfeited equity awards under the 2003 Plan will also become available for issuance under the 2012 Plan. The term of an incentive stock option may not exceed 10 years, except that with respect to any participant who owns more than 10% of the voting power of all classes or our outstanding stock, the term must not exceed five years. Options and RSUs generally vest over four years.

        These plans, other than the 2003 Plan, provide for annual automatic increases on February 1 to the shares reserved for issuance. The number of shares available for issuance under the 2012 Plan equal to the least of 10 million shares, 5% of the outstanding shares of common stock as of the last day of our immediately preceding fiscal year or such other amount as our board may determine. The number of shares available for issuance under the ESPP Plan equal to the least of 4 million shares, 2% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year or such other amount as may be determined by our board of directors.

(8) Stock Compensation Plans (Continued)

        No income tax benefit has been recognized relating to stock-based compensation expenses and $0.5 million in tax benefits have been realized from exercised stock options. At January 31, 2013, there was a total unrecognized compensation cost of $31.2 million related to these stock options, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of 3.0 years. At January 31, 2013, there was a total unrecognized compensation cost of $76.3 million related to RSUs, adjusted for estimated forfeitures, which is expected to be recognized over the next 3.8 years.

        The aggregate intrinsic value of options exercised during the fiscal year ended January 31, 2013 was $134.7 million. The weighted-average grant date fair value of options granted was $7.65 per share for the fiscal year ended January 31, 2013. The weighted-average grant date fair value of RSUs granted was $31.13 per share for the fiscal year ended January 31, 2013. The aggregate intrinsic value of RSUs vested during the fiscal year ended January 31, 2013 was $0.06 million.

        At January 31, 2012, there was a total unrecognized compensation cost of $14.9 million related to these stock options, adjusted for estimated forfeitures, which was expected to be recognized over the next 3.32 years. The total intrinsic value of options exercised during fiscal 2012 was $11.2 million. The weighted-average grant date fair value of options granted was $1.72 for fiscal 2012.

        Concurrent with the effectiveness of our registration statement on Form S-1, on April 18, 2012, our 2012 Employee Stock Purchase Plan (the "ESPP") became effective. The ESPP allows eligible employees to purchase shares of our common stock at a discount through payroll deductions of up to 15% of their eligible compensation, at not less than 85% of the fair market value, as defined in the ESPP, subject to any plan limitations. The ESPP provides for consecutive 12-month offering periods, starting on the first trading day on or after June 15 and December 15 of each year. The first offering period began on the first trading day after the effective date of our registration statement and will end on June 15, 2013.

        Stock-based compensation expense related to our stock-based awards, employee stock purchases and restricted stock units was allocated as follows:

The expected stock price volatility for our stock was determined by examining the historical volatilities of a group of our industry peers as we do not have sufficient trading history of our common stock.

        For the fiscal years ended January 31, 2013, 2012 and 2011, our tax provision consisted principally of state and foreign income tax expense. The foreign tax expense recorded for fiscal 2011 consists entirely of an estimated, uncertain tax position for which we believe it is more-likely-than-not that we will incur a tax liability. This position is related to operating in foreign jurisdictions prior to establishing a legal presence. The foreign tax expense recorded for fiscal 2013 and 2012 consists of continued estimated uncertain tax positions as well as foreign taxes from legal entities established in foreign jurisdictions during the fiscal year.

        ASC Topic 740, Income Taxes, requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that we assess that realization is more likely than not. Realization of the future tax benefits is dependent on our ability to generate sufficient taxable income within the carryforward period. Due to our history of U.S. operating losses, we believe the recognition of the deferred tax assets arising from the above mentioned future tax benefits is currently not more likely than not to be realized and, accordingly, have provided a full valuation allowance against net U.S. deferred tax assets. The valuation allowance totaled $29.2 million, $19.4 million and $16.7 million for fiscal 2013, 2012, and 2011, respectively.

        The net change in the valuation allowance was an increase of $9.8 million between fiscal 2013 and 2012, an increase of $2.7 million between fiscal 2012 and 2011 and an increase of $1.5 million between

fiscal 2011 and 2010. At January 31, 2013, we had federal and state net operating loss carryforwards of $154.9 million and $154.9 million, respectively. The net operating losses for federal and state purposes begin to expire starting in 2025 and 2016, respectively. Additionally, we had federal and state research and development tax credit carryforwards of $4.9 million and $3.9 million as of January 31, 2013 and 2012, respectively. Our federal tax credits will start to expire in 2026 if not utilized.

        If certain factors change, we may determine that there is sufficient positive evidence to support a reversal of, or decrease in, the valuation allowance. If we were to reverse all or some part of our valuation allowance our financial statements in the period of reversal would likely reflect an increase in assets on our balance sheet and a corresponding tax benefit to our statement of operations in the amount of the reversal.

        Because of certain prior period ownership changes, the utilization of a portion of our United States federal and state NOL and tax credit carryforwards may be limited. We have not finalized our analysis to determine the annual 382 limitation, but if we were to determine that certain amounts of the NOL or tax credits were limited, a portion of our deferred tax asset and valuation allowance could be adjusted.

        Effective February 1, 2009, we adopted the guidance on accounting for uncertainty in income taxes as set forth under ASC 740 Income Taxes. This guidance clarified the accounting for uncertainty in income taxes recognized in an entity's financial statements and prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken on a tax return. There was no impact upon adoption as our liability recognized under previous accounting guidance was consistent with that required under the new guidance. At January 31, 2013, our liability for uncertain tax positions was $2.1 million.

        As of January 31, 2013, $0.2 million of the liability for unrecognized tax positions would, if recognized, impact our effective tax rate. The remainder will not, if recognized, affect the effective income tax rate due to the valuation allowance that currently offsets deferred tax assets.

        The adoption of this guidance required us to identify, evaluate and measure all uncertain tax positions taken or to be taken on tax returns and to record liabilities for the amount of these positions that may not be sustained, or may only partially be sustained, upon examination by the relevant taxing authorities. Although we believe that our estimates and judgments were reasonable, actual results may differ from these estimates. Some or all of these judgments are subject to review by the taxing authorities.

Generally, we are no longer subject to United States federal, state and local tax examinations for tax years ended before December 31, 2008. However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating loss or credit carryforward.

        We accrue interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of January 31, 2013 and 2012, there was accrued interest and penalties of $90,000 and $81,000, respectively.

        We intend either to invest our non-U.S. earnings permanently in foreign operations or to remit these earnings to our United States entities in a tax-free manner. For this reason, we do not record federal income taxes on the undistributed earnings of $2 million of our foreign subsidiaries. The determination of the amount of deferred taxes on these earnings is not practicable since the computation would depend on a number of factors that cannot be known unless a decision is made to repatriate the earnings.

(11) Net Loss Per Share

        Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including preferred stock, stock options, RSUs and warrants, to the extent dilutive.

        The following table sets forth the computation of historical basic and diluted net loss per share (in thousands, except per share data):

 
   Fiscal Year Ended January 31,  
 
   2013   2012   2011  

Numerator:

                    

Net loss

   $ (36,681 ) $ (10,992 ) $ (3,806 )
               

Denominator:

                    

Weighted-average common shares outstanding

     80,465     20,921     17,755  

Less: Weighted-average unvested common shares subject to repurchase or forfeiture

     (219 )   (275 )   (17 )
               

Weighted-average shares used to compute net loss per share, basic and diluted

     80,246     20,646     17,738  
               

Net loss per share, basic and diluted

   $ (0.46 ) $ (0.53 ) $ (0.21 )
               

        Since we were in a net loss position for all periods presented, basic net loss per share is the same as diluted net loss per share for all periods as the inclusion of all common stock equivalents

(12) Related Party Transactions

        Certain members of our Board serve on the board of directors of and/or are executive officers of, and, in some cases, are investors in, companies that are customers or vendors of ours. Certain of our executive officers also serve on the board of directors of companies that are customers or vendors of ours. We believe the transactions between these companies and us were carried out on terms that are consistent with similar transactions with our other similarly situated customers or vendors. We recognized revenue from sales to these companies of $2.0 million, $1.6 million, and $0.5 for the fiscal years ended January 31, 2013, 2012 and 2011, respectively. We had $0 and $1.2 million of accounts receivable from these companies as of January 31, 2013 and January 31, 2012, respectively. We also recorded $0.9 million, $0.3 million, and $0.2 million in expenses related to purchases from these companies during the fiscal years ended January 31, 2013, 2012 and 2011, respectively. There were no accounts payable to these companies as of January 31, 2013 or January 31, 2012.

Item 9A.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

        Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of January 31, 2013. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of January 31, 2013, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management's Annual Report on Internal Control Over Financial Reporting

        This annual report does not include a report of management's assessment regarding internal control over financial reporting or an attestation report of our registered public accounting firm due to a transition period established by rules of the Securities and Exchange Commission for newly public companies.

Changes in Internal Control over Financial Reporting

        There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended January 31, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

        Our management, including our Chief Executive Officer and Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
