ITEM 1.    BUSINESS

General

We have pioneered the next generation of network security with our innovative platform that allows enterprises, service providers, and government entities to secure their networks and safely enable the increasingly complex and rapidly growing number of applications running on their networks. The core of our platform is our Next-Generation Firewall, which delivers application, user, and content visibility and control as well as protection against cyber threats integrated within the firewall through our proprietary hardware and software architecture. Our platform offers a number of compelling benefits for our end-customers, including the ability to identify, control, and safely enable applications while offering protection against cyber threats in real time. We believe our platform also offers

- 3 -

superior performance compared to legacy approaches and reduces the total cost of ownership for organizations by simplifying their network security infrastructure and eliminating the need for multiple, stand-alone security appliances. Our products and services can address a broad range of our end-customers’ network security requirements, from the data center to the network perimeter, as well as the distributed enterprise, which includes branch offices and a growing number of mobile devices.

Our platform is based on an innovative traffic classification engine that identifies network traffic by application, user, and content. As a result, it provides in-depth visibility into all traffic and all applications, at the user level, at all times, and at the full speed of the network in order to control usage, content, risks, and cyber threats. This enables our end-customers to transform their organizations by safely enabling applications through a positive security model with fine-grained policy implementation capabilities.

Our platform is delivered in the form of a hardware or virtual appliance and includes a suite of subscription services as well as support and maintenance. Our subscription services can be easily activated on any of our appliances without requiring additional hardware or processing resources, thereby providing a seamless implementation path for our end-customers. All of our appliances incorporate our PAN-OS operating system and are based on our proprietary identification technologies, application visibility and control (App-ID), user identification (User-ID), and Content-ID, which allow security policies to be defined within the context of applications, users, and content. We deliver these capabilities through an innovative, Single Pass Parallel Processing (SP3) architecture that simultaneously performs multiple identification, security, and networking functions. As a result, our end-customers achieve safe application enablement and advanced levels of cybersecurity, while maintaining high network performance.

We serve the enterprise network security market, which consists of Firewall, Unified Threat Management (UTM), Web Gateway, Intrusion Detection and Prevention (IDS/IPS), and Virtual Private Network (VPN) technologies.

We sell our platform through a high touch, channel fulfilled sales model. Our business is geographically diversified, with 63% of our total revenue from the Americas, 23% from Europe, the Middle East, and Africa (EMEA), and 14% from Asia Pacific and Japan (APAC) in fiscal 2013. As of July 31, 2013, we had over 13,500 end-customers in more than 120 countries.

We were incorporated in 2005 as Palo Alto Networks, Inc., a Delaware corporation. Our principal executive offices are located in Santa Clara, California, and our telephone number is (408) 753-4000. Our website is www.paloaltonetworks.com.

We are organized and operate in a single segment. See Note 12 to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Products and Services

Appliances. All firewall appliances come with the same rich set of features ensuring consistent operation across the entire product line. These features include: App-ID, User-ID, site-to-site VPN, remote access SSL VPN, and Quality-of-Service (QoS). We classify our appliances based on throughput. In addition to firewall appliances, we offer dedicated Panorama and WildFire appliances.

Panorama. Panorama is our centralized security management solution for global control of all of our appliances deployed on an end-customer’s network as a virtual appliance or a physical appliance. Panorama is used for centralized policy management, device management, software licensing and updates, centralized logging and reporting, and log storage. Panorama controls the security, network address translation (NAT), QoS, policy based forwarding, decryption, application override, captive portal, and DDoS/DoS protection aspects of the appliances and virtual systems under management. Panorama centrally manages device software and associated updates, including SSL-VPN clients, GlobalProtect clients, dynamic content updates, and software licenses. Panorama offers the ability to view logs and run reports from all managed appliances without the need to forward the logs and to report on aggregate user activity for all users, including mobile users. Panorama reliably expands the log storage for long-term event investigation and analysis through high-availability features for central management.

Virtual System Upgrades. Virtual System Upgrades are available as extensions to the Virtual System capacity that ships with the appliance. Virtual Systems provide a virtualization solution to our large enterprise and service provider end-customers that implement large data centers, private cloud, and public cloud security infrastructures and need to support a multi-tenant firewall environment.

Subscription Services. We offer a number of subscription services as part of our platform. These services include:

• Threat Prevention Subscription. This service provides the intrusion detection and prevention capabilities of our platform. Our threat prevention engine blocks vulnerability exploits, viruses, spyware, buffer overflows, denial-of-service attacks, and port scans from compromising and damaging enterprise information resources. It includes mechanisms such as protocol decoder-based analysis, protocol anomaly-based protection, stateful pattern matching, statistical anomaly detection, heuristic-based analysis, custom vulnerability, and spyware phone home signatures.

• URL Filtering Subscription. This service provides the URL filtering capabilities of our platform. The URL filtering database consists of millions of URLs across many categories and is designed to monitor and control employee web surfing activities. The on-appliance URL database can be augmented to suit the traffic patterns of the local user community with a custom URL database. URLs that are not categorized by the local URL database can be pulled into a separate, cache-based URL database from a very extensive, cloud-based URL database.

• GlobalProtect Subscription. This service provides protection for mobile users of both traditional laptop devices and mobile devices. It expands the boundaries of the physical network, effectively establishing a logical perimeter that encompasses remote laptop and mobile device users irrespective of their location. When a remote user logs into the device, GlobalProtect automatically determines the closest gateway available to the roaming device and establishes a secure connection. Windows and Apple laptops as well as such mobile devices as Apple iPhones and iPads, will stay connected to the corporate network whenever they are on a network of any kind. As a result they are protected as if they never left the corporate campus. GlobalProtect ensures that the same secure application enablement policies that protect users at the corporate site are enforced for all users, independent of their location.

• WildFire Subscription. This service provides protection against targeted modern malware and advanced persistent threats. Its cloud-based analysis service provides a near real-time analysis engine for detecting previously unseen modern malware. The core component of this service is a sandbox environment that can operate on an end-customers' private cloud or our public cloud where files can be run and monitored for more than 100 behavioral characteristics that identify the file as malware. Once identified, signatures are automatically generated and delivered to all devices that subscribe to the service. By providing this as a cloud-based service, all of our end-customers benefit from malware found on any network.

Support and Maintenance. We offer technical support on our products and subscriptions to our end-customers and channel partners. We offer Standard Support, Premium Support, and 4-hour Premium Support. Our channel partners that operate a Palo Alto Networks Authorized Support Center (ASC) typically deliver level-one and level-two support. We provide level-three support 24 hours a day, seven days a week through regional support centers that are located worldwide. We also offer an annual subscription-based Technical Account Management (TAM) service that provides dedicated support for end-customers with unique or complex support requirements. We offer our end-customers ongoing maintenance services for both hardware and software in order to receive ongoing security updates, PAN-OS upgrades, bug fixes, and repair. These services are typically sold to end-customers for a one-year or longer term at the time of the initial product sale and typically renew for successive one-year or longer periods. Additionally, we provide expedited replacement for any defective hardware. We use a third-party logistics provider to manage our worldwide deployment of spare appliances and other accessories.

Professional Services. Professional services include on-location, hands-on experts that plan, design, and deploy effective security solutions tailored to our end-customers’ specific requirements. We generally do not directly provide such professional services to our end-customers. Instead, we primarily deliver these resources through our authorized partners. These services include application traffic management, solution design and planning, configuration, and firewall migration. Our Education Services provide classroom-style training and are primarily delivered through our authorized partners.

Major Product Development Projects

We continue to invest in innovation and strengthening our product portfolio, which resulted in several new product offerings during fiscal 2013. These new product offerings include: the VM-Series, an all-software virtualized next-generation firewall platform that brings next-generation network security into the virtualized data center environment; the paid subscription service for WildFire, our cloud-based modern malware prevention service platform; the WF-500 appliance which provides the ability to deploy WildFire in a customer's private cloud; the PA-3000 Series firewalls that provide mid-range appliance options for enterprise customers; and lastly, the M-100 management appliance, which offers an easy to deploy, high-performance, dedicated appliance for our Panorama management system.

Technology

We combine our proprietary SP3 hardware and software architecture and PAN-OS operating system to provide a comprehensive network security platform. The core of our platform is our Next-Generation Firewall, which integrates application visibility and control and is comprised of three identification technologies, App-ID, User-ID, and Content-ID. These technologies allow organizations to enable the secure use of applications while managing the inherent risks of doing so. These fine-grained policy management and enforcement capabilities are delivered at low latency, multi-gigabit performance through our innovative SP3 architecture.

App-ID. Our application classification engine, called App-ID, uses multiple identification techniques to determine the exact identity of applications traversing the network. App-ID is the foundational classification engine that provides the core traffic classification to all other functions in our platform. The App-ID classification is used to invoke other security functions.

- 5 -

App-ID uses a series of classification techniques to accurately identify an application. When traffic first enters the network, App-ID applies an initial policy check based on IP protocol and port. Signatures are then applied to the traffic to identify the application based on application properties and related transaction characteristics. If the traffic is encrypted and a decryption policy is in place, the application is first decrypted, then application signatures are applied. Additional context-based signature analysis is then performed to identify known protocols that may be hiding other applications. Encrypted traffic that was decrypted is then re-encrypted before being sent back into the network. For evasive applications that cannot be identified through advanced signature and protocol analysis, heuristics or behavioral analysis are used to determine the identity of the application. When an application is accurately identified during this series of successive techniques, the policy check determines how to treat the application and associated functions. The policy check can block the application, allow it and scan for threats, inspect it for unauthorized file transfer and data patterns, or shape its use of network resources by applying a quality-of-service policy.

App-ID consistently classifies all network traffic, including business applications, consumer applications, and network protocols, across all ports. Consequently, there is no need to perform a series of signature checks to look for an application that is thought to be on the network. App-ID continually monitors the state of the application to determine if the application changes. Our platform only allows applications within the policy to enter the network, while all other applications are blocked.

Internally developed or custom applications can be managed using either an application override or custom App-IDs. End-customers can use either of these mechanisms to apply the same level of control over their internal or custom applications that they apply to common applications. Because the application landscape is constantly changing, our research teams are constantly updating our App-ID classification engine. We deliver updated App-IDs automatically to our end-customers through our weekly update service.

User-ID. User-ID integrates our platform with a wide range of enterprise user directories and technologies, including Active Directory, eDirectory, Open LDAP, Citrix Terminal Server, Microsoft Exchange, Microsoft Terminal Server, and ZENworks. A network-based, User-ID agent communicates with the domain controllers, directories, or supported enterprise applications, mapping information such as user, role, and current IP address to the firewall, making the policy integration transparent. In cases where user repository information does not include the current IP address of the user, a transparent, captive portal authentication or challenge/response mechanism can be used to tie users into the security policy. In cases where a user repository or application is in place that already has knowledge of users and their current IP address, a standards-based API can be used to tie the repository to our platform.

Content-ID. Content-ID is a collection of technologies that enables many of our subscription services. Content-ID combines a real-time threat prevention engine, a cloud-based analysis service, and a comprehensive URL categorization database to limit unauthorized data and file transfers, detect and block a wide range of threats, and control non-work related web surfing.

The threat prevention engine blocks several common types of attacks, including vulnerability exploits, buffer overflows, and port scans from compromising and damaging enterprise information resources. It includes mechanisms such as protocol decoder-based analysis, protocol anomaly-based protection, stateful pattern matching, statistical anomaly detection, heuristic-based analysis, custom vulnerability, and spyware “phone home” signatures.

Our cloud-based analysis service, called WildFire, provides a near real-time analysis engine for detecting previously unseen modern malware. The core component of WildFire is a sandbox environment that can be deployed in a customer's private cloud or on Palo Alto Networks' public cloud where files can be run and monitored for more than 100 behavioral characteristics that identify the file as malware. Once identified, signatures are automatically generated and delivered to all devices that subscribe to the WildFire service. By providing WildFire as a cloud-based service, all of our end-customers benefit from malware found on a single network.

Our URL filtering database consists of millions of URLs across many categories and is designed to monitor and control employee web surfing activities. The on-appliance URL database can be augmented to suit the traffic patterns of the local user community with a custom URL database. URLs that are not categorized by the local URL database can be pulled into an on-appliance data cache from a very extensive, cloud-based URL database. The data filtering features in our platform enable policies that reduce the risks associated with the transfer of unauthorized files and data. This can be achieved by blocking files by type, by controlling sensitive data, such as credit card and social security numbers in application content or attachments, and by controlling file transfers within applications.

SP3. SP3 has two elements: single-pass software and parallel processing hardware.

Our single-pass software accomplishes two key functions in our platform. First, it performs operations once per packet. As a packet is processed, the networking functions, the policy lookup, the application identification and decoding, and the signature matching for any and all threats and content are all performed simultaneously. This significantly reduces the amount of processing required to perform multiple functions in one security device. Second, the content scanning step is stream-based and uses uniform signature matching to detect and block threats. Instead of using multiple scanning passes and file proxies, which require download prior to scanning, our single-pass software scans content once in a stream-based fashion to minimize latency. This results in very high throughput and low latency, even with all security functions active. It also offers a single, fully integrated policy, thus enabling easier management of enterprise network security.

- 6 -

Our parallel processing hardware is designed to optimize single-pass software performance through the use of separate data and control planes, which means that heavy utilization of one does not negatively impact the performance of the other. Our hardware also uses discrete, specialized processing groups to perform critical functions. On the data plane, this includes functions such as networking, policy enforcement, encryption and decryption, decompression, and content scanning. On the control plane, this includes configuration management, logging, and reporting.

We believe that the combination of single-pass software and parallel processing hardware is unique in the network security industry and allows our platform to safely enable applications and prevent cyber threats at very high levels of performance and throughput.

PAN-OS Operating System. The PAN-OS operating system provides the foundation for our network security platform and contains App-ID, User-ID, and Content-ID. PAN-OS performs the core functions of our platform while also providing the networking, security, and management functions needed for implementation. The PAN-OS networking functions include dynamic routing, switching, high availability, and VPN support, which enables deployment into a broad range of networking environments.

Our platform has the ability to enable a series of virtual firewall instances or virtual systems. Each virtual system is an independent (virtual) firewall within the device that is managed separately and cannot be accessed or viewed by any other administrator of any other virtual system. This capability allows enterprises and service providers to separate firewall instances in departmental and multi-tenant managed services scenarios.

The security functions in PAN-OS are implemented in a single security policy and include application, application function, user, group, port, and service-based elements. Policy responses can range from open (allow but monitor for activity), to moderate (enabling certain applications or functions), to closed (deny). The tight integration of application control, users, and groups, and the ability to scan the allowed traffic for a wide range of threats minimizes the number of policies.

PAN-OS also includes attack protection capabilities, such as blocking invalid or malformed packets, IP defragmentation, TCP reassembly, and network traffic normalization. PAN-OS eliminates invalid and malformed packets, while TCP reassembly and IP de-fragmentation is performed to ensure the utmost accuracy and protection despite any attack evasion techniques.

Certifications. Our products have been awarded FIPS 140-2 Level 2, Common Criteria/NIAP EAL 2, Common Criteria/NIAP EAL4+, NEBS, and ICSA Firewall certifications.

Customers

We sell our platform through our channel partners to end-customers globally. Our end-customers are predominantly medium to large enterprises, service providers, and government entities. Our end-customers operate in a variety of industries, including education, energy, financial services, healthcare, Internet and media, manufacturing, public sector, and telecommunications. Our end-customers deploy our platform for a variety of security functions across a variety of deployment scenarios. Typical deployment scenarios include the enterprise perimeter, the enterprise data center, and the distributed enterprise perimeter. Our end-customer deployments typically involve at least one pair of our products along with one or more of our subscription services, depending on size, security needs and requirements, and network complexity. As of July 31, 2013, we had shipped our products to over 13,500 end-customers worldwide. No single end-customer accounted for more than 10% of our total revenue in fiscal 2013.

Backlog

Orders for services for multiple years are billed upfront shortly after receipt of an order and are included in deferred revenue. Timing of revenue recognition for services may vary depending on the contractual service period or when the services are rendered. Products are shipped and billed shortly after receipt of an order. We do not believe that our product backlog at any particular time is meaningful because it is not necessarily indicative of future revenue in any given period as such orders may be rescheduled by our partners without penalty prior to shipment or delayed due to inventory constraints. Additionally, the majority of our product revenue comes from orders that are received and shipped in the same quarter.

Sales, Customer Support and Marketing

Sales. Our sales organization is responsible for large-account acquisition and overall market development, which includes the management of the relationships with our channel partners, working with our channel partners in winning and supporting end-customers through a direct-touch approach, and acting as the liaison between the end-customers and the marketing and product development organizations. For additional information about revenue and assets by geographic region, refer to Note 12 to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K. We expect to continue to grow our sales headcount in all of our principal markets and expand our presence into countries where we currently do not have a direct sales presence.

- 7 -

Our sales organization is supported by sales engineers with responsibility for pre-sales technical support, solutions engineering for our end-customers, and technical training for our channel partners.

Channel Program. We work with channel partners that provide our platform to end-customers. We focus on building in-depth relationships with a smaller number of solutions-oriented partners that have strong network security expertise. As of July 31, 2013, we had approximately 1,250 channel partners. These channel partners are supported by our sales and marketing organization and consist of distributors and resellers with proven network security experience. Sales to these channel partners are subject to our standard, non-exclusive distributor agreement, which provides for an initial term of one year, one year renewal terms, termination by us with 30-90 days written notice prior to the renewal date, and payment to us from the channel partner within 30-45 calendar days of the date we issue an invoice for such sales. Approximately 64% of our total revenue in fiscal 2013 was derived from sales to three channel partners.

To ensure optimal productivity, we operate a formal accreditation program for our channel partners’ sales and technical professionals. Around the world, we maintain a two-tier open distribution model where value-added distributors and value-added resellers work together on a non-exclusive basis to market our platform, identify and close sales opportunities, and provide pre-sales and post-sales services to our end-customers. Our channel partner program, NextWave, rewards our channel partners based on a number of attainment goals, as well as provides them access to marketing funds, technical and sales training, and support.

Customer Support.Our customer support organization is responsible for delivering support, professional, and educational services directly to our channel partners and to end-customers. We leverage the capabilities of our channel partners and train them in the delivery of support, professional, and educational services to ensure these services are locally delivered. We believe that a broad range of support services is essential to the successful customer deployment and ongoing support of our products, and we have hired support engineers with proven experience to provide those services.

Marketing. Our marketing is focused on building our brand reputation and the market awareness of our platform, driving pipeline and end-customer demand, and operating the channel program. The marketing team consists primarily of product marketing, programs marketing, field marketing, channel marketing, and public relations functions. Marketing is responsible for the channel program NextWave, as well as the channel enablement functions. Marketing activities include pipeline development through demand generation, social media and advertising programs, managing the corporate web site and partner portal, trade shows and

conferences, press, analyst, and customer relations, and customer awareness. Every six months, we publish 2 major market research papers called the “Application Usage and Risk Report” and the “Modern Malware Report,” which are based on the application and cyber threat landscape of our end-customers. These activities and tools benefit both our direct and indirect channels and are available at no cost to our channel partners.

Manufacturing

The manufacturing of our security products is outsourced to various contract manufacturers and original design manufacturers. This approach allows us to reduce our costs as it reduces our manufacturing overhead and inventory and also allows us to adjust more quickly to changing end-customer demand. Our primary manufacturing partner is Flextronics International, Ltd., who assembles our products using design specifications, quality assurance programs, and standards that we establish, and procures components and assembles our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions.

We have entered into a written agreement with Flextronics pursuant to which they manufacture, assemble, and test our products. This agreement has an initial term of three years, which is automatically renewed for one-year terms, unless terminated by either party giving 180 days or more notice prior to the end of the term or upon written notice, subject to applicable cure periods, if the other party has materially breached its obligations under the agreement.

The component parts within our products are either sourced by our contract manufacturers or by various suppliers. We do not have any long-term manufacturing contracts that guarantee us any fixed capacity or pricing, which increases our exposure to supply shortages or price fluctuations related to raw materials.

Research and Development

Our research and development effort is focused on developing new hardware and software and on enhancing and improving our existing products. We believe that hardware and software both are critical to expanding our leadership in enterprise network security. Our engineering team has deep networking and security expertise and works closely with end-customers to identify their current and future needs. In addition to our focus on hardware and software, our research and development team is focused on research into applications and threats, which allows us to respond to the rapidly changing application and threat landscape.

We believe that innovation and timely development of new features and products is essential to meeting the needs of our end-customer and improving our competitive position. We supplement our own research and development effort with technologies and

- 8 -

products that we license from third parties. We test our products thoroughly to certify and ensure interoperability with third-party hardware and software products.

We plan to continue to significantly invest in resources to conduct our research and development effort.

Competition

We operate in the intensely competitive network security market that is characterized by constant change and innovation. Changes in the application, threat, and technology landscape result in evolving customer requirements for the protection from threats and the safe enablement of applications. Our main competitors fall into four categories:

• large networking vendors such as Cisco Systems, Inc. and Juniper Networks, Inc. that incorporate network security features in their products;

• large companies such as Intel Corporation, International Business Machines (IBM), and Hewlett-Packard Company (HP) that have acquired large network security specialist vendors in recent years and have the technical and financial resources to bring competitive solutions to the market;

• independent network security vendors such as Check Point Software Technologies Ltd. and Fortinet, Inc. that offer network security products; and

• small and large companies that offer point solutions that compete with some of the features present in our platform.

As our market grows, it will attract more highly specialized vendors as well as larger vendors that may continue to acquire or bundle their products more effectively.

The principal competitive factors in our market include:

• product features, reliability, performance, and effectiveness;

• product line breadth, diversity, and applicability;

• product extensibility and ability to integrate with other technology infrastructures;

• price and total cost of ownership;

• adherence to industry standards and certifications;

• strength of sales and marketing efforts; and

• brand awareness and reputation.

We believe we generally compete favorably with our competitors on the basis of these factors as a result of the features and performance of our platform, the ease of integration of our products with technological infrastructures, and the relatively low total cost of ownership of our products. However, many of our competitors have substantially greater financial, technical, and other resources, greater name recognition, larger sales and marketing budgets, broader distribution, more diversified product lines, and larger and more mature intellectual property portfolios.

Intellectual Property

Companies in the enterprise network security industry own large numbers of patents, copyrights, trademarks, domain names, and trade secrets and frequently enter into litigation based on allegations of infringement, misappropriation or other violations of intellectual property or other rights. Our success depends in part upon our ability to protect our core technology and intellectual property. We rely on patents, trademarks, copyrights and trade secret laws, confidentiality procedures, and employee disclosure and invention assignment agreements to protect our intellectual property rights.

As of July 31, 2013, we had 19 issued patents and 55 patent applications pending in the United States. Our issued patents expire between 2017 and 2029. We cannot assure you whether any of our patent applications will result in the issuance of a patent or whether the examination process will require us to narrow our claims. Any patents that may issue may be contested, circumvented, found unenforceable or invalidated, and we may not be able to prevent third parties from infringing them. We purchased a portion of our issued U.S. patents from other entities. We also license software from third parties for integration into our products, including open source software and other software available on commercially reasonable terms.

We control access to and use of our proprietary software and other confidential information through the use of internal and external controls, including contractual protections with employees, contractors, end-customers and partners, and our software is

- 9 -

protected by U.S. and international copyright laws. Despite our efforts to protect our trade secrets and proprietary rights through intellectual property rights, licenses, and confidentiality agreements, unauthorized parties may still copy or otherwise obtain and use our software and technology. In addition, we intend to continue to expand our international operations, and effective patent, copyright, trademark, and trade secret protection may not be available or may be limited in foreign countries.

If we become more successful, we believe that competitors will be more likely to try to develop products and services that are similar to ours and that may infringe our proprietary rights. It may also be more likely that competitors or other third parties will claim that our platform infringes their proprietary rights.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the network security industry have extensive patent portfolios and are regularly involved in both offensive and defensive litigation. From time to time, third parties, including certain of these leading companies, may assert patent, copyright, trademark, and other intellectual property rights against us, our channel partners, or our end-customers, which our standard license and other agreements obligate us to indemnify against such claims. Successful claims of infringement by a third party could prevent us from distributing certain products or performing certain services, require us to expend time and money to develop non-infringing solutions, or force us to pay substantial damages (including treble damages if we are found to have willfully infringed patents or copyrights), royalties or other fees. In addition, to the extent that we gain greater visibility and market exposure as a public company, we face a higher risk of being the subject of intellectual property infringement claims from third parties. We cannot assure you that we do not currently infringe, or that we will not in the future infringe, upon any third-party patents or other proprietary rights. See “Risk Factors—Claims by others that we infringe their proprietary technology or other rights could harm our business” and “—Legal Proceedings” below for additional information.

Employees

As of July 31, 2013, we had 1,147 full-time employees. None of our employees is represented by a labor organization or is a party to any collective bargaining arrangement. We have never had a work stoppage, and we consider our relationship with our employees to be good.

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.

Risks Related to Our Business and Our Industry

Our limited operating history makes it difficult to evaluate our current business and future prospects, and may increase the risk of your investment.

We were founded in 2005 and shipped our first products in 2007. The majority of our revenue growth has occurred since 2009. Our limited operating history makes it difficult to evaluate our current business and our future prospects, including our ability to plan for and model future growth. We have encountered and will continue to encounter risks and difficulties frequently experienced by rapidly growing companies in constantly evolving industries, including the risks described in this Annual Report on Form 10-K. If we do not address these risks successfully, our business and operating results will be adversely affected, and our stock price could decline. Further, we have limited historical financial data, and we operate in a rapidly evolving market. As such, any predictions about our future revenue and expenses may not be as accurate as they would be if we had a longer operating history or operated in a more predictable market.

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

We have experienced rapid growth and increased demand for our products over the last few years. Our employee headcount and number of end-customers have increased significantly, and we expect to continue to grow our headcount significantly over the next year. For example, from the end of fiscal 2012 to the end of fiscal 2013, our headcount increased from more than 750 to1,147 employees, and our number of end-customers increased from approximately 9,000 to over 13,500. The growth and expansion of our business and product and service offerings places a continuous significant strain on our management, operational, and financial resources. As we have grown, we have increasingly managed more complex deployments of our products and services with larger end-customers. To manage any future growth effectively, we must continue to improve and expand our information technology and financial infrastructure, our operating and administrative systems, and our ability to manage headcount, capital, and processes in an efficient manner.

We may not be able to successfully implement improvements to our systems and processes in an efficient or timely manner, and we may discover deficiencies in our existing systems and processes. We have licensed technology from third parties to help us accomplish this objective. We have continued to improve and customize our enterprise resource planning system since its launch in the second quarter of fiscal 2013. We may experience difficulties in managing improvements to our systems and processes or in connection with third-party software, which could disrupt existing customer relationships, cause us to lose customers, limit us to smaller deployments of our products, or increase our technical support costs. Our failure to improve our systems and processes, or their failure to operate in the intended manner, may result in our inability to manage the growth of our business and to accurately forecast our revenue, expenses, and earnings, or to prevent certain losses. In addition, our systems and processes may not prevent or detect all errors, omissions, or fraud. Our productivity and the quality of our products and services may be adversely affected if we do not integrate and train our new employees quickly and effectively. Any future growth would add complexity to our organization and require effective coordination throughout our organization. For example, as a result of growth in our employee headcount, on September 20, 2012, we entered into two lease agreements for an aggregate of approximately 300,000 square feet of space in Santa Clara, California to serve as our new corporate headquarters beginning in November 2013. We expect to incur additional expense in connection with the two new leases and the relocation of our headquarters, and we expect that the relocation could disrupt our operations and distract our management team. In the fourth quarter of fiscal 2013, we entered into a sublease agreement for our existing headquarters beginning in January 2014. Failure to manage any future growth effectively could result in increased costs, negatively impact our end-customers’ satisfaction with our products and services, and harm our operating results.

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

Our operating results, in particular, our revenues, gross and operating margins, and operating expenses,have historically varied from period to period, and we expect that this trend will continue as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

• our ability to attract and retain new end-customers;

- 11 -

• the budgeting cycles and purchasing practices of end-customers;

• changes in end-customer, distributor or reseller requirements, or market needs;

• changes in the growth rate of the enterprise network security market;

• the timing and success of new product and service introductions by us or our competitors or any other change in the competitive landscape of our industry, including consolidation among our competitors or end-customers;

• changes in mix of our products and services including increases in multi-year subscriptions and support and maintenance;

• price competition;

• deferral of orders from end-customers in anticipation of new products or product enhancements announced by us or our competitors;

• our ability to successfully expand our business domestically and internationally;

• our ability to increase the size of our distribution channel;

• decisions by potential end-customers to purchase enterprise network security solutions from larger, more established security vendors or from their primary network equipment vendors;

• changes in end-customer attach rates and renewal rates for our services;

• timing of revenue recognition and revenue deferrals;

• our ability to manage production and manufacturing related costs, global customer service organization costs, inventory excess and obsolescence costs, and warranty costs;

• insolvency or credit difficulties confronting our customers, which could adversely affect their ability to purchase or pay for our products and services, or confronting our key suppliers, including our sole source suppliers, which could disrupt our supply chain;

• any disruption in our channel or termination of our relationship with important channel partners, including as a result of consolidation among distributors and resellers of network security solutions;

• our inability to fulfill our end-customers’ orders due to supply chain delays or events that impact our manufacturers or their suppliers;

• the cost and potential outcomes of existing and future litigation, which could have a material adverse effect on our business;

• seasonality or cyclical fluctuations in our markets;

• future accounting pronouncements or changes in our accounting policies;

• the impact on our overall effective tax rate caused by any reorganization in our corporate structure or any changes in our valuation allowance for domestic deferred assets;

• increases or decreases in our expenses caused by fluctuations in foreign currency exchange rates, as an increasing portion of our expenses are incurred and paid in currencies other than the U.S. dollar; and

• general macroeconomic conditions, both domestically and in our foreign markets.

Any one of the factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our financial and other operating results. This variability and unpredictability could result in our failure to meet our revenue, margin, or other operating result expectations or those of securities analysts or investors for a particular period. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our common stock could fall substantially, and we could face costly lawsuits, including securities class action suits.

We are involved in litigation in which Juniper alleges that our appliances infringe seven of its patents. If Juniper prevails in the litigation, we could be required to pay substantial damages for past sales of any infringing appliances, enjoined from

- 12 -

manufacturing, using, selling, and importing such appliances if a license or other right to continue selling our appliances is not made available to us, and required to pay substantial ongoing royalties and comply with unfavorable terms if such a license is made available to us.

In December 2011, Juniper filed a lawsuit against us in the United States District Court for the District of Delaware, alleging that our appliances infringe six of its U.S. patents. One or both of Nir Zuk and Yuming Mao are named inventors on each of the patents being asserted against us. Both Mr. Zuk and Mr. Mao were employed by NetScreen Technologies, Inc., which was acquired by Juniper in April 2004. Mr. Zuk left Juniper in 2005 and founded Palo Alto Networks in that same year. Mr. Mao joined Palo Alto Networks in 2006. Juniper seeks preliminary and permanent injunctions against infringement, treble damages, and attorney’s fees. On February 9, 2012, we filed an answer to Juniper’s complaint, which denied that we infringed Juniper’s patents and asserted that Juniper’s patents were invalid.

On February 28, 2012, Juniper filed a motion to strike our defense of invalidity based on the legal doctrine of “assignor estoppel.” Under the doctrine of assignor estoppel, an inventor of a patented invention who assigns the patent to another for value cannot later challenge the validity of the patent. Under some circumstances, courts have held that the doctrine of assignor estoppel applies not only to the assigning inventor but also to a company in privity with the inventor. On March 23, 2012, we filed a brief in opposition to that motion. Juniper filed a brief in response on April 2, 2012. On August 2, 2012, the District Court issued an order granting Juniper’s motion as to one of the patents in suit (the ’634 patent) but denying Juniper’s motion as to the five other patents in suit. Pursuant to the order, we will not be able to argue in the District Court that the ’634 patent is invalid. Under the Court’s order, however, we are not precluded from arguing that our appliances do not infringe the ’634 patent. Juniper may re-assert its position on the doctrine of assignor estoppel as to the other patents in suit at later stages of the proceedings.

On September 4, 2012, Juniper filed a motion to amend its complaint to allege that our appliances infringe two additional U.S. patents (the added patents) but also to withdraw its allegations as to a previously-asserted patent (the withdrawn patent). This amended complaint was officially filed on September 25, 2012, pursuant to a stipulation between the parties. Juniper now alleges that our appliances infringe seven of its patents. On October 12, 2012, we filed an answer to Juniper’s amended complaint, which denied that we infringed Juniper’s patents and asserted that Juniper’s patents were invalid. In light of the District Court’s prior order granting Juniper’s assignor estoppel motion as to one of the patents in suit (the ‘634 patent), we do not intend to argue in the District Court that the ‘634 patent is invalid, and we do not intend to argue in the District Court that one of the two newly-asserted patents (the ‘752 patent) is invalid.

On September 13, 2012, we filed with the U.S. Patent and Trademark Office requests for inter partes reexamination of five of the six patents asserted by Juniper in its original complaint. We did not file a request for reexamination on the withdrawn patent. The Patent and Trademark Office has since issued decisions on our requests for reexaminations. On October 19, 2012 and December 3, 2012, the Patent and Trademark Office granted our requests for reexamination as to three patents (the '459, '700 and '634 patents) rejecting a number of the claims asserted in the litigation, and on November 15, 2012 and 26, 2012, the Patent and Trademark Office denied our requests for reexamination as to two other patents (the '723 and '347 patents). We have the opportunity to seek review of these denials within the Patent and Trademark Office, and have done so with respect to one of the patents (the '723 patent). On June 20, 2013 and July 23, 2013, we filed with the U.S. Patent and Trademark Office petitions for inter partes review for two other patents asserted by Juniper in the litigation (the '612 and '752 patents). The Patent and Trademark Office has not yet ruled on those petitions. Should any claim challenged in our reexamination requests be finally determined to be valid and patentable, we may be precluded in litigation from challenging any such patent claim on invalidity grounds that were or could have been raised during the inter partes reexamination proceedings.

The judge has issued a scheduling order which sets forth the current expectation for important events in the lawsuit, although no assurances can be given that the schedule will not change. On June 18, 2012 and on October 12, 2012, Juniper served infringement contentions, which, among other things, assert that each of our products that run our PAN-OS operating system infringes each of the Juniper patents-in-suit. We served our invalidity contentions on Juniper on July 18, 2012 and, for the newly-asserted patents, on November 19, 2012. Each party served its opening expert report on April 12, 2013, and rebuttal expert report on May 13, 2013, and supplemental expert reports on June 11, 2013. The parties filed opening and responsive briefs regarding claim construction (also known as Markman), filed their opening summary judgment briefs on August 20, 2013, and filed opposition briefs and additional summary judgment motions on September 12, 2013. A hearing to resolve claim construction issues, as well as motions for summary judgment, is scheduled to be heard on November 15, 2013, and a trial date has been scheduled for February 24, 2014. Pursuant to the Court’s general standing order, the February 2014 trial will be limited to determining whether the patents (other than the ’634 and ’752 patents) are valid and whether we infringe one or more valid patents. Thereafter, the Court will rule on any post-trial motions and enter a judgment on validity and infringement. According to the Court’s general standing order, if Juniper were to prevail on one or more of its patents, a subsequent trial on damages would be scheduled following an appeal on the liability issues to the appellate court.

Should Juniper prevail on its claims that one or more of our appliances infringe one or more of its valid patents, we could be required to pay substantial damages for past sales of such appliances, enjoined from manufacturing, using, selling, and importing such appliances if a license or other right to continue selling our appliances is not made available to us, and required to pay substantial

- 13 -

ongoing royalties and comply with unfavorable terms if such a license is made available to us. Any of these outcomes could result in a material adverse effect on our business. Even if we were to prevail, this litigation will be costly and time-consuming, divert the attention of our management and key personnel from our business operations, deter distributors from selling our appliances, and dissuade potential end-customers from purchasing our appliances, which would also materially harm our business. During the course of litigation, we anticipate announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of our common stock may decline.

We are vigorously defending the lawsuit. At this stage in the litigation, we are unable to predict the likelihood of success of Juniper’s infringement claims.

Our revenue growth rate in recent periods may not be indicative of our future performance.

You should not consider our revenue growth rate in recent periods as indicative of our future performance. We have recently experienced revenue growth rates of 55% and 115% in fiscal 2013 and 2012, respectively. We do not expect to achieve similar revenue growth rates in future periods. You should not rely on our revenue for any prior quarterly or annual periods as any indication of our future revenue or revenue growth. If we are unable to maintain consistent revenue or revenue growth, our stock price could be volatile, and it may be difficult to achieve and maintain profitability.

We have a history of losses, anticipate increasing our operating expenses in the future, and may not be able to maintain or increase profitability or cash flow on a consistent basis. If we cannot maintain or increase our profitability or cash flow, our business, financial condition, and operating results may suffer.

Other than fiscal 2012, we have incurred losses in all fiscal years since our inception. We incurred a net loss of $29.2 million in fiscal 2013, $12.5 million in fiscal 2011, and $21.1 million in fiscal 2010. As a result, we had an accumulated deficit of $109.3 million at July 31, 2013. We anticipate that our operating expenses will increase substantially in the foreseeable future as we continue to enhance our product and service offerings, broaden our end-customer base, expand our sales channels, expand our operations, hire additional employees, and continue to develop our technology. These efforts may prove more expensive than we currently anticipate, and we may not succeed in increasing our revenues sufficiently, or at all, to offset these higher expenses. Revenue growth may slow or revenue may decline for a number of possible reasons, including slowing demand for our products or services, increasing competition, a decrease in the growth of our overall market, or a failure to capitalize on growth opportunities. Any failure to increase our revenues as we grow our business could prevent us from maintaining or increasing profitability or cash flow on a consistent basis. If we are unable to meet these risks and challenges as we encounter them, our business, financial condition, and operating results may suffer.

If we are unable to sell additional products and services to our end-customers, our future revenue and operating results will be harmed.

Our future success depends, in part, on our ability to expand the deployment of our platform with existing end-customers by selling additional products to secure other areas of our end-customers’ network and by upselling additional subscription services to provide increasing levels of network security. This may require increasingly sophisticated and costly sales efforts and may not result in additional sales. In addition, the rate at which our end-customers purchase additional products and services depends on a number of factors, including the perceived need for additional network security products and services as well as general economic conditions. If our efforts to sell additional products and services to our end-customers are not successful, our business may suffer.

Further, existing end-customers that purchase our subscriptions have no contractual obligation to renew their contracts after the initial contract period, which is typically one year, and we cannot accurately predict renewal rates. Our end-customers’ renewal rates may decline or fluctuate as a result of a number of factors, including their satisfaction with our services and our end-customer support, the frequency and severity of subscription outages, our product uptime or latency, and the pricing of our, or competing, services. If our end-customers renew their subscriptions, they may renew for shorter contract lengths or on other terms that are less economically beneficial to us. We have limited historical data with respect to rates of end-customer renewals, so we may not accurately predict future renewal trends. We cannot assure you that our end-customers will renew their subscriptions, and if our end-customers do not renew their agreements or renew on less favorable terms, our revenues may grow more slowly than expected or decline.

We also depend on our installed end-customer base for future support and maintenance revenues. Our support and maintenance agreements are typically one year. If end-customers choose not to continue renewing their support and maintenance or seek to renegotiate the terms of support and maintenance agreements prior to renewing such agreements, our revenue may decline.

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

The market for network security products is intensely competitive, and we expect competition to increase in the future from established competitors and new market entrants. Our current competitors include networking companies such as Cisco Systems, Inc. and Juniper, large companies, such as Intel Corporation, International Business Machines (IBM), and Hewlett-Packard (HP) that have

- 14 -

acquired large network security vendors in recent years, security vendors such as Check Point Software Technologies, Ltd. and Fortinet, Inc., and other point solution security vendors. New, privately held companies, as well as established public companies, are currently attempting to enter this market, some of which may become significant competitors in the future. Many of our existing competitors have, and some of our potential competitors could have, substantial competitive advantages such as:

• greater name recognition and longer operating histories;

• larger sales and marketing budgets and resources;

• broader distribution and established relationships with distribution partners and end-customers;

• greater customer support resources;

• greater resources to make acquisitions;

• lower labor and development costs;

• larger and more mature intellectual property portfolios; and

• substantially greater financial, technical, and other resources.

In addition, some of our larger competitors have substantially broader and more diverse product offerings and leverage their relationships based on other products or incorporate functionality into existing products to gain business in a manner that discourages users from purchasing our products, including through selling at zero or negative margins, product bundling, or closed technology platforms. Potential end-customers may also prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. These larger competitors often have broader product lines and market focus and may therefore not be as susceptible to downturns in a particular market. Many of our smaller competitors that specialize in providing protection from a single type of network security threat are often able to deliver these specialized network security products to the market more quickly than we can. Conditions in our market could change rapidly and significantly as a result of technological advancements, partnering by our competitors or continuing market consolidation. New start-up companies that innovate and large competitors that are making significant investments in research and development may invent similar or superior products and technologies that compete with our products and technology. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources.

Some of our competitors have made acquisitions of businesses that may allow them to offer more directly competitive and comprehensive solutions than they had previously offered, such as Intel’s acquisition of McAfee and Stonesoft, Check Point’s acquisition of Nokia’s security appliance business, and Cisco's pending acquisition of SourceFire. As a result of such acquisitions, our current or potential competitors might be able to adapt more quickly to new technologies and end-customer needs, devote greater resources to the promotion or sale of their products and services, initiate or withstand substantial price competition, take advantage of acquisition or other opportunities more readily, or develop and expand their product and service offerings more quickly than we do. Due to various reasons, organizations may be more willing to incrementally add solutions to their existing network security infrastructure from competitors than to replace it with our solutions. These competitive pressures in our market or our failure to compete effectively may result in price reductions, fewer orders, reduced revenue and gross margins, and loss of market share. Any failure to meet and address these factors could seriously harm our business and operating results.

If functionality similar to that offered by our products is incorporated into existing network infrastructure products, organizations may decide against adding our appliances to their network, which would have an adverse effect on our business.

Large, well-established providers of networking equipment such as Cisco and Juniper offer, and may continue to introduce, network security features that compete with our products, either in stand-alone security products or as additional features in their network infrastructure products. The inclusion of, or the announcement of an intent to include, functionality perceived to be similar to that offered by our security solutions in networking products that are already generally accepted as necessary components of network architecture may have an adverse effect on our ability to market and sell our products. Furthermore, even if the functionality offered by network infrastructure providers is more limited than our products, a significant number of end-customers may elect to accept such limited functionality in lieu of adding appliances from an additional vendor such as us. Many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep relationships with other providers of networking products, which may make them reluctant to add new components to their networks, particularly from other vendors such as us. In addition, an organization’s existing vendors or new vendors with a broad product offering may be able to offer concessions that we are not able to match because we currently offer only network security products and have fewer resources than many of our competitors. If organizations are reluctant to add additional network infrastructure from new vendors or otherwise decide to work with their existing vendors, our ability to increase our market share and improve our financial condition and operating results will be adversely affected.

- 15 -

Reliance on shipments at the end of the quarter could cause our revenue for the applicable period to fall below expected levels.

As a result of end-customer buying patterns and the efforts of our sales force and channel partners to meet or exceed their sales objectives, we have historically received a substantial portion of sales orders and generated a substantial portion of revenue during the last few weeks of each fiscal quarter. If expected revenue at the end of any fiscal quarter is delayed for any reason, including the failure of anticipated purchase orders to materialize, our logistics partners’ inability to ship products prior to fiscal quarter-end to fulfill purchase orders received near the end of the fiscal quarter, our failure to manage inventory to meet demand, our inability to release new products on schedule, any failure of our systems related to order review and processing, or any delays in shipments based on trade compliance requirements, our revenue for that quarter could fall below our expectations, resulting in a decline in the trading price of our common stock.

If we are unable to hire, retain, train, and motivate qualified personnel and senior management, our business could suffer.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel, or delays in hiring required personnel, particularly in engineering and sales, may seriously harm our business, financial condition, and operating results. Although we have entered into employment offer letters with our key personnel, these agreements have no specific duration and constitute at-will employment. We are also substantially dependent on the continued service of our existing development personnel because of the complexity of our platform. Additionally, any failure to hire, train, and adequately incentivize our sales personnel could negatively impact our growth. Further, the inability of our recently hired sales personnel to effectively ramp to target productivity levels could negatively impact our operating margins. If we are not effective in managing the leadership transition in our sales organization, our business could be adversely impacted and our operating results and financial condition could be harmed.

Competition for highly skilled personnel is often intense, especially in the San Francisco Bay Area where we have a substantial presence and need for highly skilled personnel. We may not be successful in attracting, integrating, or retaining qualified personnel to fulfill our current or future needs. Also, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited, or that they have divulged proprietary or other confidential information, or that their former employers own their inventions or other work product.

Our future performance also depends on the continued services and continuing contributions of our senior management to execute on our business plan and to identify and pursue new opportunities and product innovations. The loss of services of senior management could significantly delay or prevent the achievement of our development and strategic objectives, which could adversely affect our business, financial condition, and operating results.

Our employees do not have employment arrangements that require them to continue to work for us for any specified period, and therefore, they could terminate their employment with us at any time. We do not maintain key person life insurance policies on any of our employees. The loss of one or more of our key employees or groups could seriously harm our business.

We rely on third-party channel partners to sell substantially all of our products, and if our partners fail to perform, our ability to sell and distribute our products and services will be limited, and our operating results will be harmed.

Substantially all of our revenue is generated by sales through our channel partners, including distributors and resellers. We provide our sales channel partners with specific training and programs to assist them in selling our products, but there can be no assurance that these steps will be effective. In addition, our channel partners may be unsuccessful in marketing, selling, and supporting our products and services. If we are unable to develop and maintain effective sales incentive programs for our third-party channel partners, we may not be able to incentivize these partners to sell our products to end-customers and, in particular, to large enterprises. These partners may also market, sell, and support products and services that are competitive with ours and may devote more resources to the marketing, sales, and support of such competitive products. These partners may have incentives to promote our competitors’ products to the detriment of our own or may cease selling our products altogether. Our agreements with our channel partners may generally be terminated for any reason by either party with advance notice prior to each annual renewal date. We cannot assure you that we will retain these channel partners or that we will be able to secure additional or replacement channel partners. The loss of one or more of our significant channel partners or a decline in the number or size of orders from them could harm our operating results. In addition, any new sales channel partner requires extensive training and may take several months or more to achieve productivity. Our channel partner sales structure could subject us to lawsuits, potential liability, and reputational harm if, for example, any of our channel partners misrepresent the functionality of our products or services to end-customers or violate laws or our corporate policies. If we fail to effectively manage our existing sales channels, or if our channel partners are unsuccessful in fulfilling the orders for our products, or if we are unable to enter into arrangements with, and retain a sufficient number of, high quality channel partners in each of the regions in which we sell products and keep them motivated to sell our products, our ability to sell our products and operating results will be harmed.

Because we depend on third-party manufacturers to build and ship our products, we are susceptible to manufacturing and logistics delays and pricing fluctuations that could prevent us from shipping customer orders on time, if at all, or on a cost-effective basis, which may result in the loss of sales and customers.

We depend on third-party manufacturers, primarily Flextronics International Ltd., our contract manufacturer, as sole source manufacturers for our product lines. Our reliance on these third-party manufacturers reduces our control over the manufacturing process and exposes us to risks, including reduced control over quality assurance, product costs, and product supply and timing, as well as the risk that minerals which originate from the Democratic Republic of the Congo and adjoining countries, or conflicts minerals, may be included in our products. Any manufacturing and logistics disruption by these third-party manufacturers could severely impair our ability to fulfill orders. In addition, we are subject to new requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act that will require us to diligence, disclose and report whether or not our products contain conflicts minerals. The implementation of these new requirements could adversely affect the sourcing, availability and pricing of minerals used in the manufacture of semiconductor devices or other components used in our products. In addition, we will incur additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products.

These manufacturers typically fulfill our supply requirements on the basis of individual orders. We do not have long term contracts with our third-party manufacturers that guarantee capacity, the continuation of particular pricing terms, or the extension of credit limits. Accordingly, they are not obligated to continue to fulfill our supply requirements, which could result in supply shortages, and the prices we are charged for manufacturing services could be increased on short notice. Our contract with one of our contract manufacturers permits them to terminate the agreement for their convenience, subject to prior notice requirements. If we are required to change contract manufacturers, our ability to meet our scheduled product deliveries to our customers could be adversely affected, which could cause the loss of sales to existing or potential customers, delayed revenue or an increase in our costs which could adversely affect our gross margins. Any production interruptions for any reason, such as a natural disaster, epidemic, capacity shortages, or quality problems, at one of our manufacturing partners would negatively affect sales of our product lines manufactured by that manufacturing partner and adversely affect our business and operating results.

Managing the supply of our products and product components is complex. Insufficient supply and inventory may result in lost sales opportunities or delayed revenue, while excess inventory may harm our gross margins.

Our third-party manufacturers procure components and build our products based on our forecasts, and we generally do not hold inventory for a prolonged period of time. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and analyses from our sales and marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate component supply, from time to time we may issue forecasts for components and products that are non-cancelable and non-returnable.

Our inventory management systems and related supply chain visibility tools may be inadequate to enable us to forecast accurately and effectively manage supply of our products and product components. Supply management remains an increased area of focus as we balance the need to maintain supply levels that are sufficient to ensure competitive lead times against the risk of obsolescence because of rapidly changing technology and end-customer requirements. If we ultimately determine that we have excess supply, we may have to reduce our prices and write-down inventory, which in turn could result in lower gross margins. If our actual component usage and product demand are lower than the forecast we provide to our contract manufacturer, we accrue for losses on manufacturing commitments in excess of forecasted demand. Alternatively, insufficient supply levels may lead to shortages that result in delayed revenue or loss of sales opportunities altogether as potential end-customers turn to competitors’ products that are readily available. Additionally, any increases in the time required to manufacture our products or ship products could result in supply shortfalls. If we are unable to effectively manage our supply and inventory, our operating results could be adversely affected.

Because some of the key components in our products come from limited sources of supply, we are susceptible to supply shortages or supply changes, which could disrupt or delay our scheduled product deliveries to our customers and may result in the loss of sales and customers.

Our products rely on key components, including integrated circuit components, which our contract manufacturers purchase on our behalf from a limited number of suppliers, including sole source providers. The manufacturing operations of some of our component suppliers are geographically concentrated in Asia and elsewhere, which makes our supply chain vulnerable to regional disruptions. A fire, flood, earthquake, tsunami or other disaster, condition or event such as political instability, civil unrest or a power outage that adversely affects any of these component suppliers’ facilities could significantly affect our ability to obtain the necessary components for our products, which could result in a substantial loss of sales and revenue and a substantial harm to our operating results. Similarly, a localized health risk affecting employees at these facilities, such as the spread of a pandemic influenza, could impair the total volume of components that we are able to obtain, which could result in substantial harm to our operating results.

- 17 -

We do not have volume purchase contracts with any of our component suppliers, and they could cease selling to us at any time. In addition, our component suppliers change their selling prices frequently in response to market trends, including industry-wide increases in demand, and because we do not have contracts with these suppliers, we are susceptible to price fluctuations related to raw materials and components. If we are unable to pass component price increases along to our customers or maintain stable pricing, our gross margins and operating results could be negatively impacted. If we are unable to obtain a sufficient quantity of these components in a timely manner for any reason, sales of our products could be delayed or halted or we could be forced to expedite shipment of such components or our products at dramatically increased costs, which would negatively impact our revenue and gross margins. Additionally, poor quality in any of the sole-sourced components in our products could result in lost sales or lost sales opportunities. If the quality of the components does not meet our or our end-customers’ requirements, if we are unable to obtain components from our existing suppliers on commercially reasonable terms, or if any of our sole source providers cease to remain in business or continue to manufacture such components, we could be forced to redesign our products and qualify new components from alternate suppliers. The resulting stoppage or delay in selling our products and the expense of redesigning our products could result in lost sales opportunities and damage to customer relationships, which would adversely affect our business and operating results.

If we are not successful in executing our strategy to increase sales of our products to new and existing medium and large enterprise end-customers, our operating results may suffer.

Our growth strategy is dependent, in part, upon increasing sales of our products to medium and large enterprises. Sales to these types of end-customers involve risks that may not be present (or that are present to a lesser extent) with sales to smaller entities. These risks include:

• competition from larger competitors, such as Cisco, Check Point, and Juniper, that traditionally target larger enterprises, service providers, and government entities and that may have pre-existing relationships or purchase commitments from those end-customers;

• increased purchasing power and leverage held by large end-customers in negotiating contractual arrangements with us;

• more stringent requirements in our worldwide support service contracts, including stricter support response times and penalties for any failure to meet support requirements; and

• longer sales cycles and the associated risk that substantial time and resources may be spent on a potential end-customer that elects not to purchase our products and services.

Large enterprises often undertake a significant evaluation process that results in a lengthy sales cycle, in some cases over 12 months. Although we have a channel sales model, our sales representatives typically engage in direct interaction with our distributors and resellers in connection with sales to larger end-customers. Because these evaluations are often lengthy, with significant size and scope and stringent requirements, we typically provide evaluation products to these end-customers. We may spend substantial time, effort, and money in our sales efforts without being successful in generating any sales. In addition, product purchases by large enterprises are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing, and other delays. Finally, large enterprises typically have longer implementation cycles, require greater product functionality and scalability and a broader range of services, demand that vendors take on a larger share of risks, sometimes require acceptance provisions that can lead to a delay in revenue recognition, and expect greater payment flexibility from vendors. All of these factors can add further risk to business conducted with these end-customers. If we fail to realize an expected sale from a large end-customer in a particular quarter or at all, our business, operating results, and financial condition could be materially and adversely affected.

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

Services revenue accounts for a significant portion of our revenue, comprising 38% of total revenue in fiscal 2013, 32% of total revenue in fiscal 2012, and 28% of total revenue for fiscal 2011. Sales of new or renewal subscription and support and maintenance contracts may decline and fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors, and reductions in our end-customers’ spending levels. If our sales of new or renewal subscription and support and maintenance contracts decline, our revenue and revenue growth may decline and our business will suffer. In addition, we recognize subscription and support and maintenance revenue monthly over the term of the relevant service period, which is typically one year and can be up to five years. As a result, much of the subscription and support and maintenance revenue we report each fiscal quarter is the recognition of deferred revenue from subscription and support and maintenance contracts entered into during previous fiscal quarters. Consequently, a decline in new or renewed subscription or support and maintenance contracts in any one fiscal quarter will not be fully reflected in revenue in that fiscal quarter but will negatively affect our revenue in future fiscal quarters. Accordingly, the effect of significant downturns in new or renewed sales of our subscriptions or support and maintenance is not reflected in full in our operating results until future

- 18 -

periods. Also, it is difficult for us to rapidly increase our services revenue through additional service sales in any period, as revenue from new and renewal service contracts must be recognized over the applicable service period. Furthermore, any increase in the average term of services contracts would result in revenue for services contracts being recognized over longer periods of time.

Defects, errors, or vulnerabilities in our products or services or the failure of our products or services to block a virus or prevent a security breach could harm our reputation and adversely impact our results of operations.

Because our products and services are complex, they have contained and may contain design or manufacturing defects or errors that are not detected until after their commercial release and deployment by our end-customers. For example, from time to time, certain of our end-customers have reported defects in our products related to performance, scalability and compatibility that were not detected before shipping the product. Additionally, defects may cause our products or services to be vulnerable to security attacks, cause them to fail to help secure networks or temporarily interrupt end-customers’ networking traffic. Because the techniques used by computer hackers to access or sabotage networks change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques and provide a solution in time to protect our end-customers’ networks. Furthermore, as a well-known provider of network security solutions, our networks, products, and services could be targeted by attacks specifically designed to disrupt our business and harm our reputation. In addition, defects or errors in our subscription updates or our products could result in a failure of our services to effectively update end-customers’ hardware products and thereby leave our end-customers vulnerable to attacks. Our data centers and networks may experience technical failures and downtime, may fail to distribute appropriate updates, or may fail to meet the increased requirements of a growing end-customer base, any of which could temporarily or permanently expose our end-customers’ networks, leaving their networks unprotected against the latest security threats.

Any defects, errors or vulnerabilities in our products could result in:

• expenditure of significant financial and product development resources in efforts to analyze, correct, eliminate, or work-around errors or defects or to address and eliminate vulnerabilities;

• loss of existing or potential end-customers or channel partners;

• delayed or lost revenue;

• delay or failure to attain market acceptance;

• an increase in warranty claims compared with our historical experience, or an increased cost of servicing warranty claims, either of which would adversely affect our gross margins; and

• litigation, regulatory inquiries, or investigations that may be costly and harm our reputation.

Our business is subject to the risks of warranty claims, product returns, product liability, and product defects.

Our products are very complex and, despite testing prior to their release, they have contained and may contain undetected defects or errors, especially when first introduced or when new versions are released. Product defects or errors could affect the performance of our products and could delay the development or release of new products or new versions of products, adversely affect our reputation and our end-customers’ willingness to buy products from us, and adversely affect market acceptance or perception of our products. Any such errors or delays in releasing new products or new versions of products or allegations of unsatisfactory performance could cause us to lose revenue or market share, increase our service costs, cause us to incur substantial costs in redesigning the products, cause us to lose significant end-customers, subject us to liability for damages and divert our resources from other tasks, any one of which could materially and adversely affect our business, results of operations and financial condition. Our products must successfully interoperate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the sources of these problems. For example, from time to time certain of our end-customers have experienced temporary delays or interoperability issues when implementing our products in large complex global deployments where our products are required to interoperate with a complex environment of third party products. The occurrence of hardware or software errors, whether or not caused by our products, could delay or reduce market acceptance of our products, and have an adverse effect on our business and financial performance, and any necessary revisions may cause us to incur significant expenses. The occurrence of any such problems could harm our business, financial condition and results of operations.

- 19 -

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

If the network security market does not continue to adopt our network security platform, our sales will not grow as quickly as anticipated, and our stock price could decline.

We are seeking to disrupt the network security market with our network security platform. However, organizations that use legacy products and services for their network security needs may believe that these products and services sufficiently achieve their purpose. Organizations may also believe that our products and services only serve the needs of a portion of the network security market. Accordingly, organizations may continue allocating their IT budgets for legacy products and services and may not adopt our network security platform. If the market for network security solutions does not continue to adopt our network security platform, if end-customers do not recognize the value of our platform compared to legacy products and services, or if we are otherwise unable to sell our products and services to organizations, then our revenue may not grow or may decline, which would have a material adverse effect on our operating results and financial condition.

If we do not accurately predict, prepare for, and respond promptly to the rapidly evolving technological and market developments and changing end-customer needs in the network security market, our competitive position and prospects will be harmed.

The network security market is expected to continue to evolve rapidly. Moreover, many of our end-customers operate in markets characterized by rapidly changing technologies and business plans, which require them to add numerous network access points and adapt increasingly complex enterprise networks, incorporating a variety of hardware, software applications, operating systems, and networking protocols. The technology in our products is especially complex because it needs to effectively identify and respond to new and increasingly sophisticated methods of attack, while minimizing the impact on network performance. Additionally, some of our new products and enhancements may require us to develop new hardware architectures that involve complex, expensive, and time-consuming research and development processes. Although the market expects rapid introduction of new products or product enhancements to respond to new threats, the development of these products is difficult and the timetable for commercial release and availability is uncertain as there can be long time periods between releases and availability of new products. We may experience unanticipated delays in the availability of new products and services and fail to meet customer expectations for such availability. If we do not quickly respond to the rapidly changing and rigorous needs of our end-customers by developing, releasing, and making available on a timely basis new products and services or enhancements that can respond adequately to new security threats, our competitive position and business prospects will be harmed.

Additionally, the process of developing new technology is complex and uncertain, and if we fail to accurately predict end-customers’ changing needs and emerging technological trends in the network security industry, including the areas of mobility, virtualization, cloud computing and software defined networks (SDN), our business could be harmed. We must commit significant resources to developing new products before knowing whether our investments will result in products the market will accept. The success of new products depends on several factors, including appropriate new product definition, component costs, timely completion and introduction of these products, differentiation of new products from those of our competitors, and market acceptance of these products. There can be no assurance that we will successfully identify new product opportunities, develop and bring new products to market in a timely manner, or achieve market acceptance of our products, or that products and technologies developed by others will not render our products or technologies obsolete or noncompetitive.

Our current research and development efforts may not produce successful products or features that result in significant revenue, cost savings or other benefits in the near future, if at all.

Developing our products and related enhancements is expensive. Our investments in research and development may not result in significant design improvements, marketable products or features or may result in products that are more expensive than anticipated. Additionally, we may not achieve the cost savings or the anticipated performance improvements we expect, and we may take longer to generate revenue, or generate less revenue, than we anticipate. Our future plans include significant investments in research and development and related product opportunities. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position. However, we may not receive significant revenue from these investments in the near future, if at all, or these investments may not yield the expected benefits, either of which could adversely affect our business and operating results.

The sales prices of our products and services may decrease, which may reduce our gross profits and adversely impact our financial results.

The sales prices for our products and services may decline for a variety of reasons, including competitive pricing pressures, discounts, a change in our mix of products and services, anticipation of the introduction of new products or services, or promotional programs. Competition continues to increase in the market segments in which we participate, and we expect competition to further increase in the future, thereby leading to increased pricing pressures. Larger competitors with more diverse product and service offerings may reduce the price of products or services that compete with ours or may bundle them with other products and services. Additionally, although we price our products and services worldwide in U.S. dollars, currency fluctuations in certain countries and regions may negatively impact actual prices that partners and end-customers are willing to pay in those countries and regions. Furthermore, we anticipate that the sales prices and gross profits for our products will decrease over product life cycles. We cannot assure you that we will be successful in developing and introducing new offerings with enhanced functionality on a timely basis, or that our product and service offerings, if introduced, will enable us to maintain our prices and gross profits at levels that will allow us to achieve and maintain profitability.

We generate a significant amount of revenue from sales to distributors, resellers, and end-customers outside of the United States, and we are therefore subject to a number of risks associated with international sales and operations.

We have a limited history of marketing, selling, and supporting our products and services internationally. As a result, we must hire and train experienced personnel to staff and manage our foreign operations. To the extent that we experience difficulties in recruiting, training, managing, and retaining an international staff, and specifically staff related to sales management and sales personnel, we may experience difficulties in sales productivity in foreign markets. We also enter into strategic distributor and reseller relationships with companies in certain international markets where we do not have a local presence. If we are not able to maintain successful strategic distributor relationships internationally or recruit additional companies to enter into strategic distributor relationships, our future success in these international markets could be limited. Business practices in the international markets that we serve may differ from those in the United States and may require us in the future to include terms other than our standard terms in customer contracts, although to date we generally have not done so. To the extent that we may enter into customer contracts in the future that include non-standard terms related to payment, warranties, or performance obligations, our operating results may be adversely impacted.

Additionally, our international sales and operations are subject to a number of risks, including the following:

• economic uncertainty around the world, in particular, macroeconomic challenges in Europe;

• greater difficulty in enforcing contracts and accounts receivable collection and longer collection periods;

• the uncertainty of protection for intellectual property rights in some countries;

• greater risk of unexpected changes in regulatory practices, tariffs, and tax laws and treaties;

• risks associated with trade restrictions and foreign legal requirements, including the importation, certification, and localization of our products required in foreign countries;

• greater risk of a failure of foreign employees, partners, distributors, and resellers to comply with both U.S. and foreign laws, including antitrust regulations, the U.S. Foreign Corrupt Practices Act, and any trade regulations ensuring fair trade practices;

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

• increased expenses incurred in establishing and maintaining office space and equipment for our international operations;

• greater difficulty in recruiting local experienced personnel, and the costs and expenses associated with such activities;

• management communication and integration problems resulting from cultural and geographic dispersion;

• fluctuations in exchange rates between the U.S. dollar and foreign currencies in markets where we do business; and

• general economic and political conditions in these foreign markets.

These factors and other factors could harm our ability to gain future international revenues and, consequently, materially impact our business, operating results, and financial condition. The expansion of our existing international operations and entry into additional international markets will require significant management attention and financial resources. Our failure to successfully manage our international operations and the associated risks effectively could limit the future growth of our business.

- 21 -

We are exposed to the credit and liquidity risk of some of our channel partners and to credit exposure in weakened markets, which could result in material losses.

For fiscal 2013, three channel partners represented 64% of our total revenue, and as of July 31, 2013, four channel partners represented 76% of our gross accounts receivable. Most of our sales to our channel partners are made on an open credit basis. Although we have programs in place that are designed to monitor and mitigate these risks, we cannot assure you these programs will be effective in reducing our credit risks, especially as we expand our business internationally. If we are unable to adequately control these risks, our business, operating results, and financial condition could be harmed.

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

Sales to U.S. and foreign, federal, state, and local governmental agency end-customers have accounted for an increasingly significant amount of our revenue, and we may in the future increase sales to government entities. Sales to government entities are subject to a number of risks. Selling to government entities can be highly competitive, expensive, and time-consuming, often requiring significant upfront time and expense without any assurance that these efforts will generate a sale. Government certification requirements for products like ours may change, thereby restricting our ability to sell into the federal government sector until we have attained the revised certification. Government demand and payment for our products and services may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our products and services.

The substantial majority of our sales to date to government entities have been made indirectly through our channel partners. Government entities may have statutory, contractual or other legal rights to terminate contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our future operating results. Governments routinely investigate and audit government contractors’ administrative processes, and any unfavorable audit could result in the government refusing to continue buying our products and services, a reduction of revenue or fines or civil or criminal liability if the audit uncovers improper or illegal activities, which could adversely impact our operating results in a material way. Finally, for purchases by the U.S. government, the government may require certain products to be manufactured in the United States and other relatively high cost manufacturing locations, and we may not manufacture all products in locations that meet the requirements of the U.S. government, affecting our ability to sell these products to the U.S. government.

Sequestration or other actions of the U.S. Government resulting in significant cuts in U.S. Government spending could adversely affect our sales and future results.

The Budget Control Act of 2011 (Budget Control Act), which raised the U.S. national debt ceiling and put into effect a series of actions for deficit reduction, triggered automatic reductions in U.S. Government spending, known as “sequestration,” beginning in 2013. While Congress and the Administration continue to debate how the nation should proceed on these issues, the outcome of that debate could have a significant impact on future U.S. Government spending plans, including the overall spending on network security by the various agencies of the U.S. Government. Our sales and future results may be adversely impacted by reductions in U.S. Government spending as a result of sequestration.

If our products do not interoperate with our end-customers’ infrastructure, sales of our products and services could be negatively affected, which would harm our business.

Our products must interoperate with our end-customers’ existing infrastructure, which often have different specifications, utilize multiple protocol standards, deploy products from multiple vendors, and contain multiple generations of products that have been added over time. As a result, when problems occur in a network, it may be difficult to identify the sources of these problems. If we find defects in the hardware, we replace the hardware as part of our normal warranty process. If we find errors in the existing software that create problematic network configurations or settings, as we have in the past, we may have to issue software updates as part of our normal maintenance process. Any delays in identifying the sources of problems or in providing necessary modifications to our software or hardware could have a negative impact on our reputation and our end-customers’ satisfaction with our products and services, and our ability to sell products and services could be adversely affected. In addition, government and other end-customers may require our products to comply with certain security or other certifications and standards. If our products are late in achieving or fail to achieve compliance with these certifications and standards, or our competitors achieve compliance with these certifications and standards, we may be disqualified from selling our products to such end-customers, or at a competitive disadvantage, which would harm our business, operating results, and financial condition.

Our ability to sell our products is dependent on the quality of our and our channel partners’ technical support services, and our or our channel partners’ failure to offer high quality technical support services could have a material adverse effect on our end-customers’ satisfaction with our products and services, our sales, and our operating results.

Once our products are deployed within our end-customers’ networks, our end-customers depend on our technical support services, as well as the support of our channel partners, to resolve any issues relating to our products. Our channel partners often

- 22 -

provide similar technical support for third parties’ products, and may therefore have fewer resources to dedicate to the support of our products. If we or our channel partners do not effectively assist our end-customers in deploying our products, succeed in helping our end-customers quickly resolve post-deployment issues, or provide effective ongoing support, our ability to sell additional products and services to existing end-customers would be adversely affected and our reputation with potential end-customers could be damaged. Many larger enterprise, service provider, and government entity end-customers have more complex networks and require higher levels of support than smaller end-customers. If we or our channel partners fail to meet the requirements of the larger end-customers, it may be more difficult to execute on our strategy to increase our coverage with larger end-customers. Additionally, if our channel partners do not effectively provide support to the satisfaction of our end-customers, we may be required to provide direct support to such end-customers, which would require us to hire additional personnel and to invest in additional resources. It can take several months to recruit, hire, and train qualified technical support employees. We may not be able to hire such resources fast enough to keep up with unexpected demand, particularly when the sales of our products exceed our internal forecasts. To the extent that we or our partners are unsuccessful in hiring, training, and retaining adequate support resources, our and our channel partners’ ability to provide adequate and timely support to our end-customers will be negatively impacted, and our end-customers’ satisfaction with our products and services will be adversely affected. Additionally, to the extent that we may need to rely on our sales engineers to provide post-sales support while we are ramping our support resources, our sales productivity will be negatively impacted, which would harm our revenues. Our or our channel partners failure to provide and maintain high quality support services would have a material adverse effect on our business, financial condition, and operating results.

False detection of applications, viruses, spyware, vulnerability exploits, data patterns or URL categories could adversely affect our business.

Our classifications of application type, virus, spyware, vulnerability exploits, data, or URL categories may falsely detect applications, content, or threats that do not actually exist. This risk is heightened by the inclusion of a “heuristics” feature in our products, which attempts to identify applications and other threats not based on any known signatures but based on characteristics or anomalies which indicate that a particular item may be a threat. These false positives, while typical in our industry, may impair the perceived reliability of our products and may therefore adversely impact market acceptance of our products. If our products restrict important files or applications based on falsely identifying them as malware or some other item that should be restricted, this could adversely affect end-customers’ systems and cause material system failures. Any such false identification of important files or applications could result in damage to our reputation, negative publicity, loss of end-customers and sales, increased costs to remedy any problem, and costly litigation.

Claims by others that we infringe their proprietary technology or other rights could harm our business.

Companies in the enterprise network security industry own large numbers of patents, copyrights, trademarks, domain names, and trade secrets and frequently enter into litigation based on allegations of infringement, misappropriation, or other violations of intellectual property or other rights. As we face increasing competition and gain an increasingly high profile, the possibility of intellectual property rights claims against us grows. Third parties have asserted and may in the future assert claims of infringement of intellectual property rights against us. For example, beginning in January 2009, Fortinet, Inc. began filing a series of complaints against us alleging, among other claims, patent infringement. We entered into a settlement agreement with Fortinet, Inc. in January 2011 which included a three-year covenant by each party not to sue the other party for patent related claims. This covenant not to sue expires in January 2014. Third parties may also assert such claims against our end-customers or channel partners, whom our standard license and other agreements obligate us to indemnify against claims that our products infringe the intellectual property rights of third parties. As the number of products and competitors in our market increases and overlaps occur, infringement claims may increase. While we intend to increase the size of our patent portfolio, our competitors and others may now and in the future have significantly larger and more mature patent portfolios than we have. In addition, future litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents may therefore provide little or no deterrence or protection. In addition, we have not registered our trademarks in all of our geographic markets and failure to secure those registrations could adversely affect our ability to enforce and defend our trademark rights. Any claim of infringement by a third party, even those without merit, could cause us to incur substantial costs defending against the claim, could distract our management from our business and could require us to cease use of such intellectual property. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. Refer to the discussion under “Legal Proceedings” included in Part I, Item 3 of this Annual Report on Form 10-K for information related to pending litigation.

Although third parties may offer a license to their technology or other intellectual property, the terms of any offered license may not be acceptable and the failure to obtain a license or the costs associated with any license could cause our business, financial condition, and operating results to be materially and adversely affected. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. If a third party does not offer us a license to its technology or other intellectual property on reasonable terms, or at all, we could be enjoined from continued use of such intellectual property. As a result, we may be required to develop alternative, non-infringing technology, which could require significant time (during which we would be unable to continue to offer our affected products or services), effort, and expense and may ultimately not

- 23 -

be successful. Furthermore, a successful claimant could secure a judgment or we may agree to a settlement that prevents us from distributing certain products or performing certain services or that requires us to pay substantial damages, royalties or other fees. Any of these events could seriously harm our business, financial condition, and operating results.

Our proprietary rights may be difficult to enforce or protect, which could enable others to copy or use aspects of our products without compensating us.

We rely and expect to continue to rely on a combination of confidentiality and license agreements with our employees, consultants, and third parties with whom we have relationships, as well as trademark, copyright, patent, and trade secret protection laws, to protect our proprietary rights. We have filed various applications for certain aspects of our intellectual property. Valid patents may not issue from our pending applications, and the claims eventually allowed on any patents may not be sufficiently broad to protect our technology or products. Any issued patents may be challenged, invalidated or circumvented, and any rights granted under these patents may not actually provide adequate defensive protection or competitive advantages to us. 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 make the inventions claimed in our pending patent applications or that we were the first to file for patent protection, which could prevent our patent applications from issuing as patents or invalidate our patents following issuance. 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. In addition, recent changes to the patent laws in the United States may bring into question the validity of certain categories of software patents. As a result, we may not be able to obtain adequate patent protection or effectively enforce any issued patents.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors, and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that we have entered into such agreements with all parties who may have or have had access to our confidential information or that the agreements we have entered into will not be breached. We cannot guarantee that any of the measures we have taken will prevent misappropriation of our technology. Because we may be an attractive target for computer hackers, we may have a greater risk of unauthorized access to, and misappropriation of, our proprietary information. 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. From time to time, we may need to take legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results, and financial condition. Attempts to enforce our rights against third parties could also provoke these third parties to assert their own intellectual property or other rights against us, or result in a holding that invalidates or narrows the scope of our rights, in whole or in part. If we are unable to protect our proprietary rights (including aspects of our software and products protected other than by patent rights), we may find ourselves at a competitive disadvantage to others who need not incur the additional expense, time, and effort required to create the innovative products that have enabled us to be successful to date. Any of these events would have a material adverse effect on our business, financial condition, and operating results.

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

Our products contain software modules licensed to us by third-party authors under “open source” licenses. Some open source licenses contain requirements that we make available source code for modifications or derivative works we create based upon the type of open source software we use. If we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar products with lower development effort and time and ultimately could result in a loss of product sales for us.

Although we monitor our use of open source software to avoid subjecting our products to conditions we do not intend, the terms of many open source licenses have not been interpreted by United States courts, and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products. From time to time, there have been claims against companies that distribute or use open source software in their products and services, asserting that open source software infringes the claimants’ intellectual property rights. We could be subject to suits by parties claiming infringement of intellectual property rights in what we believe to be licensed open source software. Moreover, we cannot assure you that our processes for controlling our use of open source software in our products will be effective. If we are held to have breached the terms of an open source software license, we could be required to seek licenses from third parties to continue offering our products on terms that are not economically feasible, to re-engineer our products, to discontinue the sale of our products if re-engineering could

- 24 -

not be accomplished on a timely basis, or to make generally available, in source code form, our proprietary code, any of which could adversely affect our business, operating results, and financial condition.

In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or assurance of title or controls on origin of the software. In addition, many of the risks associated with usage of open source software, such as the lack of warranties or assurances of title, cannot be eliminated, and could, if not properly addressed, negatively affect our business. We have established processes to help alleviate these risks, including a review process for screening requests from our development organizations for the use of open source software, but we cannot be sure that all open source software is submitted for approval prior to use in our products.

Our failure to adequately protect personal information could have a material adverse effect on our business.

A wide variety of provincial, state, national, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These data protection and privacy-related laws and regulations are evolving and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. Our failure to comply with applicable laws and regulations, or to protect such data, could result in enforcement action against us, including fines, imprisonment of company officials and public censure, claims for damages by end-customers and other affected individuals, damage to our reputation and loss of goodwill (both in relation to existing end-customers and prospective end-customers), any of which could have a material adverse effect on our operations, financial performance, and business. Evolving and changing definitions of personal data and personal information, within the European Union, the United States, and elsewhere, especially relating to classification of IP addresses, machine identification, location data, and other information, may limit or inhibit our ability to operate or expand our business, including limiting strategic partnerships that may involve the sharing of data. Even the perception of privacy concerns, whether or not valid, may harm our reputation and inhibit adoption of our products by current and future end-customers.

We license technology from third parties, and our inability to maintain those licenses could harm our business.

We incorporate technology that we license from third parties, including software, into our products and services. We cannot be certain that our licensors are not infringing the intellectual property rights of third parties or that our licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. Some of our agreements with our licensors may be terminated for convenience by them. If we are unable to continue to license any of this technology because of intellectual property infringement claims brought by third parties against our licensors or against us, or if we are unable to continue our license agreements or enter into new licenses on commercially reasonable terms, our ability to develop and sell products and services containing that technology would be severely limited, and our business could be harmed. Additionally, if we are unable to license necessary technology from third parties, we may be forced to acquire or develop alternative technology of lower quality or performance standards. This would limit and delay our ability to offer new or competitive products and services and increase our costs of production. As a result, our margins, market share, and operating results could be significantly harmed.

Misuse of our products could harm our reputation and divert resources.

Our products may be misused by end-customers or third parties that obtain access to our products. For example, our products could be used to censor private access to certain information on the Internet. Such use of our products for censorship could result in negative press coverage and negatively affect our reputation.

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

Because we incorporate encryption technology into our products, certain of our products are subject to U.S. export controls and may be exported outside the U.S. only with the required export license or through an export license exception. If we were to fail to comply with U.S. export licensing requirements, U.S. customs regulations, U.S. economic sanctions, or other laws, we could be subject to substantial civil and criminal penalties, including fines, incarceration for responsible employees and managers, and the possible loss of export or import privileges. Obtaining the necessary export license for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities. Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products to U.S. embargoed or sanctioned countries, governments, and persons. Even though we take precautions to ensure that our channel partners comply with all relevant regulations, any failure by our channel partners to comply with such regulations could have negative consequences, including reputational harm, government investigations, and penalties.

In addition, various countries regulate the import of certain encryption technology, including through import permit and license requirements, and have enacted laws that could limit our ability to distribute our products or could limit our end-customers’ ability to implement our products in those countries. Changes in our products or changes in export and import regulations may create delays in the introduction of our products into international markets, prevent our end-customers with international operations from deploying our products globally or, in some cases, prevent or delay 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, shift in the enforcement or

- 25 -

scope of existing regulations, or change in the countries, governments, persons, or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential end-customers with international operations. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, financial condition, and operating results.

Our corporate culture has contributed to our success, and if we cannot maintain this culture as we grow, we could lose the innovation, creativity, and teamwork fostered by our culture, and our business may be harmed.

We believe that a critical contributor to our success has been our corporate culture, which we believe fosters innovation, teamwork, passion for customers, and focus on execution, as well as facilitating critical knowledge transfer and knowledge sharing. As we grow and change, we may find it difficult to maintain these important aspects of our corporate culture, which could limit our ability to innovate and operate effectively. Any failure to preserve our culture could also negatively affect our ability to retain and recruit personnel, continue to perform at current levels or execute on our business strategy.

We may acquire other businesses which could require significant management attention, disrupt our business, dilute stockholder value, and adversely affect our operating results.

As part of our business strategy, we may make investments in complementary companies, products, or technologies. However, we have not made any significant acquisitions to date, and as a result, our ability as an organization to acquire and integrate other companies, products or technologies in a successful manner is unproven. We may not be able to find suitable acquisition candidates, and we may not be able to complete such acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by our end-customers, investors, and securities analysts. In addition, if we are unsuccessful at integrating such acquisitions, or the technologies associated with such acquisitions, into our company, the revenue and operating results of the combined company could be adversely affected. Any integration process may require significant time and resources, and we may not be able to manage the process successfully. We may not successfully evaluate or utilize the acquired technology or personnel, or accurately forecast the financial impact of an acquisition transaction, including accounting charges. We may have to pay cash, incur debt or issue equity securities to pay for any such acquisition, each of which could adversely affect our financial condition or the value of our common stock. The sale of equity or issuance of debt to finance any such acquisitions could result in dilution to our stockholders. The incurrence of indebtedness would result in increased fixed obligations and could also include covenants or other restrictions that would impede our ability to manage our operations.

Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new products could reduce our ability to compete and could harm our business.

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 to enhance our platform, 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 equity financing, our stockholders may experience significant dilution of their ownership interests and the per share value of our common stock could decline. Furthermore, if we engage in debt financing, the holders of debt would have priority over the holders of common stock, and we may be required to accept terms that restrict our ability to incur additional indebtedness. We may also be required to take other actions that would otherwise be in the interests of the debt holders and force us to maintain specified liquidity or other ratios, any of which could harm our business, operating results, and financial condition. 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.

We may not be able to successfully manage the growth of our business if we are unable to improve our internal systems, processes, and controls.

We need to continue to improve our internal systems, processes, and controls to effectively manage our operations and growth. We may not be able to successfully implement improvements to these systems, processes, and controls in an efficient or timely manner. We have implemented a new enterprise resource planning system, and we may not be able to successfully scale improvements to our enterprise resource planning system or implement and scale other systems and processes in a timely or efficient manner or in a manner that does not negatively affect our operating results. In addition, our systems and processes may not prevent or detect all errors, omissions, or fraud. We have licensed technology from third parties to help us improve our internal systems, processes, and controls. The support services available for such third-party technology may be negatively affected by mergers and consolidation in the software industry, and support services for such technology may not be available to us in the future. We may experience difficulties in managing improvements to our systems, processes, and controls or in connection with third-party software, which could impair our ability to provide products or services to our customers in a timely manner, causing us to lose customers, limit us to smaller deployments of our products, or increase our technical support costs.

- 26 -

We recently implemented a corporate structure more closely aligned with the international nature of our business activities, and if we do not achieve increased tax benefits as a result of our corporate structure, our financial condition and results of operations could be adversely affected.

We recently reorganized our corporate structure and intercompany relationships to more closely align with the international nature of our business activities. This corporate structure may allow us to reduce our overall effective tax rate through changes in how we use our intellectual property, international procurement, and sales operations. This corporate structure may also allow us to obtain financial and operational efficiencies. These efforts will require us to incur expenses in the near term for which we may not realize related benefits. If the structure is not accepted by the applicable taxing authorities, changes in domestic and international tax laws negatively impact the structure, including proposed legislation to reform U.S. taxation of international business activities, or we do not operate our business consistent with the structure and applicable tax provisions, we may fail to achieve the financial and operational efficiencies that we anticipate as a result of the structure and our future financial condition and results of operations may be negatively impacted.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below expectations of securities analysts and investors, resulting in a decline in our stock price.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue, and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our consolidated financial statements include those related to revenue recognition, share-based compensation, contract manufacturing liabilities, warranties, loss contingencies, and income taxes.

Failure to comply with governmental laws and regulations could harm our business.

Our business is subject to regulation by various federal, state, local, and foreign governmental agencies, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, product safety, environmental laws, consumer protection laws, anti-bribery laws, import/export controls, federal securities laws, and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, civil and criminal penalties, or injunctions. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, operating results, and financial condition could be materially adversely affected. In addition, responding to any action will likely result in a significant diversion of management’s attention and resources and an increase in professional fees. Enforcement actions and sanctions could harm our business, operating results, and financial condition.

If we fail to comply with environmental requirements, our business, financial condition, operating results, and reputation could be adversely affected.

We are subject to various environmental laws and regulations including laws governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment. Examples of these laws and regulations include the European Union, or EU, Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive, or RoHS, and the EU Waste Electrical and Electronic Equipment Directive, or WEEE, as well as the implementing legislation of the EU member states. Similar laws and regulations have been passed or are pending in China, South Korea, Norway, and Japan and may be enacted in other regions, including in the United States, and we are, or may in the future be, subject to these laws and regulations.

The EU RoHS and the similar laws of other jurisdictions ban the use of certain hazardous materials such as lead, mercury, and cadmium in the manufacture of electrical equipment, including our products. Currently, the manufacturer of our hardware appliances and major component part suppliers comply with the EU RoHS requirements. However, if there are changes to this or other laws (or their interpretation) or if new similar laws are passed in other jurisdictions, we may be required to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us or disrupt our operations or logistics.

- 27 -

The WEEE Directive requires electronic goods producers to be responsible for the collection, recycling, and treatment of such products. Changes in interpretation of the directive may cause us to incur costs or have additional regulatory requirements to meet in the future in order to comply with this directive, or with any similar laws adopted in other jurisdictions.

Our failure to comply with past, present, and future similar laws could result in reduced sales of our products, substantial product inventory write-offs, reputational damage, penalties, and other sanctions, any of which could harm our business and financial condition. We also expect that our products will be affected by new environmental laws and regulations on an ongoing basis. To date, our expenditures for environmental compliance have not had a material impact on our results of operations or cash flows, and although we cannot predict the future impact of such laws or regulations, they will likely result in additional costs and may increase penalties associated with violations or require us to change the content of our products or how they are manufactured, which could have a material adverse effect on our business, operating results, and financial condition.

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

Our sales contracts are primarily denominated in U.S. dollars, and therefore, substantially all of our revenue is not subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our products to our end-customers outside of the United States, which could adversely affect our financial condition and operating results. In addition, an increasing portion of our operating expenses is incurred outside the United States, is denominated in foreign currencies, and is subject to fluctuations due to changes in foreign currency exchange rates. If we are not able to successfully hedge against the risks associated with currency fluctuations, our financial condition and operating results could be adversely affected.

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

A significant natural disaster, such as an earthquake, fire, a flood, or significant power outage could have a material adverse impact on our business, operating results, and financial condition. Both our corporate headquarters and the location where our products are manufactured are located in the San Francisco Bay Area, a region known for seismic activity. In addition, natural disasters could affect our supply chain, manufacturing vendors, or logistics providers’ ability to provide materials and perform services such as manufacturing products or assisting with shipments on a timely basis. In the event our or our service providers’ information technology systems or manufacturing or logistics abilities are hindered by any of the events discussed above, shipments could be delayed, resulting in missed financial targets, such as revenue and shipment targets, for a particular quarter. In addition, acts of terrorism and other geo-political unrest could cause disruptions in our business or the business of our supply chain, manufacturers, logistics providers, partners, or end-customers or the economy as a whole. Any disruption in the business of our supply chain, manufacturers, logistics providers, partners, or end-customers that impacts sales at the end of a fiscal quarter could have a significant adverse impact on our quarterly results. All of the aforementioned risks may be further increased if the disaster recovery plans for us and our suppliers prove to be inadequate. To the extent that any of the above should result in delays or cancellations of customer orders, or the delay in the manufacture, deployment, or shipment of our products, our business, financial condition, and operating results would be adversely affected.

Risks Related to Ownership of Our Common Stock

Our actual operating results may differ significantly from our guidance. 

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

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

- 28 -

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results will vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock. 

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

The price of our common stock may be volatile and the value of your investment could decline.

The trading price of our common stock has been volatile since our initial public offering (IPO). Since shares of our common stock were sold in our IPO in July 2012 at a price of $42.00 per share, the reported high and low sales prices of our common stock has ranged from $72.61 to $39.08, through September 10, 2013. The trading price of our common stock may fluctuate widely in response to various factors, some of which are beyond our control. These factors include:

• announcements of new products, services or technologies, commercial relationships, acquisitions or other events by us or our competitors;

• price and volume fluctuations in the overall stock market from time to time;

• significant volatility in the market price and trading volume of technology companies in general and of companies in our industry;

• fluctuations in the trading volume of our shares or the size of our public float;

• actual or anticipated changes in our operating results or fluctuations in our operating results;

• whether our operating results meet the expectations of securities analysts or investors;

• actual or anticipated changes in the expectations of securities analysts or investors;

• litigation involving us, our industry, or both, including any developments with respect to our pending litigation, described under the "Litigation" subheading in Note 6. Commitments and Contingencies of Notes to Consolidated Financial Statements in Part II, Item 8 of this Quarterly Report on Form 10-Q;

• regulatory developments in the United States, foreign countries or both;

• major catastrophic events;

• sales of large blocks of our stock;

• departures of key personnel; or

• economic uncertainty around the world, in particular, macroeconomic challenges in Europe;

In addition, if the market for technology stocks or the stock market in general experiences loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, operating results or financial condition. The trading price of our common stock might also decline in reaction to events that affect other companies in our industry even if these events do not directly affect us. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Securities litigation could result in substantial costs and divert our management’s attention and resources from our business. This could have a material adverse effect on our business, operating results and financial condition.

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 July 31, 2013, we had outstanding approximately 71,612,000 shares of our common stock.

        As of July 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.

- 29 -

The issuance of additional stock in connection with financings, acquisitions, investments, our stock incentive plans or otherwise will dilute all other stockholders.

Our amended and restated certificate of incorporation authorizes us to issue up to 1,000,000,000 shares of common stock and up to 100,000,000 shares of preferred stock with such rights and preferences as may be determined by our board of directors. Subject to compliance with applicable rules and regulations, we may issue our shares of common stock or securities convertible into our common stock from time to time in connection with a financing, acquisition, investment, our stock incentive plans or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and cause the trading price of our common stock to decline.

Insiders have substantial control over us, which could limit your ability to influence the outcome of key transactions, including a change of control.

As of July 31, 2013, our directors, executive officers and each of our stockholders who own greater than 5% of our outstanding common stock and their affiliates, in the aggregate, beneficially own approximately 35% of the outstanding shares of our common stock. As a result, these stockholders, if acting together, will be able to influence or control matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions or other extraordinary transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and might ultimately affect the market price of our common stock.

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

We have never declared or paid any dividends on our common stock. We intend to retain any earnings to finance the operation and expansion of our business, and we do not anticipate paying any cash dividends in the future. As a result, you may only receive a return on your investment in our common stock if the market price of our common stock increases.

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

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

Because we are no longer an “emerging growth company” as defined in the JOBS Act, we are subject to the independent auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, enhanced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. While we were able to determine in our management's report for fiscal 2013 that our internal control over financial reporting is effective, as well as provide an unqualified attestation report from our independent registered public accounting firm to that effect, we have and will continue to consume management resources and incur significant expenses for Section 404 compliance on an ongoing basis. In the event that our chief executive officer, chief financial officer, or independent registered public accounting firm determines in the future that our internal control over financial reporting is not effective as defined under Section 404, we could be subject to one or more investigations or enforcement actions by state or federal regulatory agencies, stockholder lawsuits or other adverse actions requiring us to incur defense costs, pay fines, settlements or judgments and causing investor perceptions to be adversely affected and potentially resulting in a decline in the market price of our stock.

In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure, such as continued rulemaking pursuant to the Dodd-Frank Act of 2010 and related rules and regulations regarding the disclosure of conflict minerals that are mandated by the Dodd-Frank Act,are creating uncertainty for public companies, increasing legal and financial compliance costs, and making some activities more time-consuming. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is

- 30 -

provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrative expense 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, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

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

We are obligated to maintain proper and effective internal controls over financial reporting. We may not complete our analysis of our internal controls 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 are required, pursuant to the Exchange Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our auditors have issued an attestation report on our internal controls.

While we were able to determine in our management's report for fiscal 2013 that our internal control over financial reporting is effective, as well as provide an unqualified attestation report from our independent registered public accounting firm to that effect, wemay not be able to complete our evaluation, testing, and any required remediation in a timely fashionor our independent registered public accounting firm may not be able to formally attest to the effectiveness of our internal control over financial reporting in the future.During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting that we are unable to remediate before the end of the same fiscal year in which the material weakness is identified, we will be unable to assert that our internal controls are effective. If we are unable to assert that our internal control over financial reporting is effective, or if our auditors are unable to attest to the effectiveness of our internal controls or determine we have a material weakness in our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline.

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

The trading market for our common stock, to some extent, depends on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us should downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts should 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.

Our charter documents and Delaware law could discourage takeover attempts and lead to management entrenchment.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it difficult for stockholders to elect directors that are not nominated by the current members of our board of directors or take other corporate actions, including effecting changes in our management. These provisions include:

• a classified board of directors with three-year staggered terms, which could delay the ability of stockholders to change the membership of a majority of our board of directors;

• the ability of our board of directors to issue shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror;

• the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

- 31 -

• a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

• the requirement that a special meeting of stockholders may be called only by the chairman of our board of directors, our president, our secretary, or a majority vote of our board of directors, which could delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors;

• the requirement for the affirmative vote of holders of at least 66 ²/₃% of the voting power of all of the then outstanding shares of the voting stock, voting together as a single class, to amend the provisions of our amended and restated certificate of incorporation relating to the issuance of preferred stock and management of our business or our amended and restated bylaws, which may inhibit the ability of an acquiror to effect such amendments to facilitate an unsolicited takeover attempt;

• the ability of our board of directors, by majority vote, to amend the bylaws, which may allow our board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquiror to amend the bylaws to facilitate an unsolicited takeover attempt; and

• advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to obtain control of us.

In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

ITEM 1B.    UNRESOLVED STAFF COMMENTS

None.

ITEM 2.    PROPERTIES

Our corporate headquarters is located in Santa Clara, California where we currently lease approximately 105,664 square feet of space under a lease agreement that expires in March 2018. On September 20, 2012, we entered into two lease agreements for an aggregate of approximately 300,000 square feet of space in Santa Clara, California to serve as our new corporate headquarters beginning in November 2013. In July 2013, we entered into a sub-lease agreement for the current corporate headquarters with a lease inception date of January 2014. We have an additional technical support center in Plano, Texas under a lease agreement that expires in October 2016. We also lease space for operations and sales personnel in locations throughout the United States and various international locations, including the Netherlands, Singapore, the United Kingdom, Japan, Australia, Canada, and France. We believe that our current facilities are adequate to meet our current needs. We intend to expand our facilities or add new facilities as we add employees and enter new geographic markets, and we believe that suitable additional or alternative space will be available as needed to accommodate ongoing operations and any such growth. However, we expect to incur additional expenses in connection with such new or expanded facilities.

ITEM 7.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included 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 Annual Report on Form 10-K.

Overview

We have pioneered the next generation of network security with our innovative platform that allows enterprises, service providers, and government entities to secure their networks and safely enable the increasingly complex and rapidly growing number of applications running on their networks. The core of our platform is our Next-Generation Firewall, which delivers application, user, and content visibility and control as well as protection against cyber threats integrated within the firewall through our proprietary hardware and software architecture. Our products and services can address a broad range of our end-customers’ network security requirements, from the data center to the network perimeter, as well as the distributed enterprise, which includes branch offices and a growing number of mobile devices.

We derive revenue from sales of our products and services, which together comprise our platform. Product revenue is primarily generated from sales of our Next-Generation Firewall which is available in hardware and virtualized platforms. All of our products incorporate our proprietary PAN-OS operating system, which provides a consistent set of capabilities across our entire product line. These capabilities include: application visibility and control (App-ID), user identification (User-ID), site-to-site VPN, remote access SSL VPN, and Quality-of-Service (QoS). Our products are designed for different performance requirements throughout an organization which range from the PA-200, which is designed for enterprise remote offices, to the PA-5060, which is designed for high-speed data centers. The same firewall functionality that is delivered in the hardware platforms is also available in the VM-Series virtual firewalls which secure virtualized and cloud-based computing environments. Multiple firewalls can leverage the WildFire appliance, WF-500, which identifies, analyzes, and blocks known and unknown malware in a private cloud-based environment. Our platform can be centrally managed in both virtualized and hardware platforms across an organization with our Panorama product.

Services revenue includes sales of subscriptions and support and maintenance. Our Threat Prevention, URL Filtering, GlobalProtect, and WildFire subscriptions provide our end-customers with real-time access to the latest antivirus, intrusion prevention, web filtering, and modern malware prevention capabilities across fixed and mobile devices. When end-customers purchase a product, they typically purchase one or more of our subscriptions for additional functionality, as well as support and maintenance in order to receive ongoing security updates, upgrades, bug fixes, and repairs. Sales of these services increase our deferred revenue balance and contribute significantly to our positive cash flow provided by operating activities.

We maintain a field sales force that works closely with our channel partners in developing sales opportunities. We use a two-tier, indirect fulfillment model whereby we sell our products and services to our global distributor channel partners, which, in turn, sell our products and services to our reseller network, which then sell to our end-customers. Our channel partners purchase our products and services at a discount to our list prices before reselling them to our end-customers. Our channel partners generally receive an order from an end-customer prior to placing an order with us and generally do not stock appliances.

For the fiscal year 2013, we added more than 4,800 new customers, including leading government organizations, large healthcare organizations, technology leaders and some of the largest Fortune 100 companies in the world. We had more than 13,500 end-customers in over 120 countries as of July 31, 2013. Our end-customers represent a broad range of industries including education, energy, financial services, healthcare, Internet and media, manufacturing, public sector, and telecommunications. During fiscal 2013, 63% of our revenue was generated from the Americas, 23% from Europe, the Middle East, and Africa (EMEA), and 14% from Asia Pacific and Japan (APAC). As of July 31, 2013, we had 1,147 employees.

We have experienced rapid growth in recent periods. For fiscal 2013, 2012, and 2011, revenues were $396.1 million, $255.1 million, and $118.6 million, respectively, representing year over year growth of 55% for fiscal 2013 and 115% for fiscal 2012, despite continued uncertainty in the macroeconomic environment, in particular, weakness in EMEA and a slowdown in spending by the U.S. Government. These macroeconomic factors may continue to impact overall spending in information technology (IT) by our customers, which could adversely affect our revenues and operating results.

We continue to invest in innovation and strengthening our product portfolio, which resulted in several new product offerings during fiscal 2013. These new product offerings include: the VM-Series, an all-software virtualized next-generation firewall platform that brings next-generation network security into the virtualized data center environment; the paid subscription service for

- 37 -

WildFire, our cloud-based modern malware prevention service platform; the WF-500 appliance which provides the ability to deploy WildFire in a customer's private cloud; the PA-3000 Series firewalls that provide mid-range appliance options for enterprise customers; and lastly, the M-100 management appliance, which offers an easy to deploy, high-performance, dedicated appliance for our Panorama management system.

Fiscal 2013 Financial Highlights

• We added over 4,800 new end-customers during fiscal 2013 and we had more than 13,500 end customers in over 120 countries as of July 31, 2013.

• Total revenue increased 55% to $396.1 million during fiscal 2013 from $255.1 million during fiscal 2012.

• Revenue increased 53% in Americas, 48% in EMEA and 82% in APAC during fiscal 2013 compared to fiscal 2012.

• Service revenue increased 89% to $152.4 million during fiscal 2013 from $80.7 million during fiscal 2012.

• Service revenue as a percentage of total revenue increased to 38% during fiscal 2013 from 32% during fiscal 2012, which reflected the increasing recurring revenue in the business model and the rapid adoption of higher margin subscriptions services in our customer base.

• As of July 31, 2013, we had $436.9 million in cash, cash equivalents, and investments.

• Cash flow provided by operating activities increased 48% to $114.5 million during fiscal 2013 from $77.4 million during fiscal 2012.

• Deferred revenue increased 84% to $249.2 million as of July 31, 2013 from $135.8 million as July 31, 2012 reflected the increased adoption of our support and maintenance and all our subscriptions services.

• We completed the reorganization of our corporate structure and intercompany relationships to more closely align with the international nature of our business activities. Through changes in international procurement and sales operations, our corporate structure may cause short-term volatility but is expected to reduce our overall effective tax rate over the long term.

We believe that the growth of our business and our short and long term success are dependent upon many factors, including our ability to extend our technology leadership, grow our base of end-customers, expand deployment of our platform within existing end-customers, and focus on end-customer satisfaction. While these areas present significant opportunities for us, they also pose challenges and risks that we must successfully address in order to sustain the growth of our business and improve our operating results.

To manage any future growth effectively, we must continue to improve and expand our information technology and financial infrastructure, our operating and administrative systems and controls, and our ability to manage headcount, capital, and processes in an efficient manner. Additionally, we face intense competition in our market, and to succeed, we need to innovate and offer products that are differentiated from existing infrastructure products, as well as effectively hire, retain, train, and motivate qualified personnel and senior management. If we are unable to successfully address these challenges, our business, operating results, and prospects could be adversely affected.

Key Financial Metrics

We monitor the key financial metrics set forth below to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts, and assess operational efficiencies. We discuss revenue, gross margin, and the components of operating income (loss) and margin below under “—Financial Overview” and “—Results of Operations.” Deferred revenue, cash flow provided by operating activities, and free cash flow(non-GAAP) are discussed immediately below the following table.

Free cash flow (non-GAAP)	$	92,077		$	62,803		$	19,102

• Deferred Revenue. Our deferred revenue consists of amounts that have been invoiced but that have not yet been recognized as revenue as of the period end. The majority of our deferred revenue balance consists of subscription and support and maintenance revenue that is recognized ratably over the contractual service period. We monitor our deferred revenue balance because it represents a significant portion of revenue to be recognized in future periods.

• Cash Flow Provided by Operating Activities. We monitor cash flow provided by operating activities as a measure of our overall business performance. Our cash flow provided by operating activities is driven in large part by sales of our products and from up-front payments for both subscriptions and support and maintenance. Monitoring cash flow provided by operating activities enables us to analyze our financial performance without the non-cash effects of certain items such as depreciation, amortization, and share-based compensation costs, thereby allowing us to better understand and manage the cash needs of our business.

• Free Cash Flow (non-GAAP). We define free cash flow, a non-GAAP financial measure, as cash provided by operating activities less purchases of property, equipment, and other assets. We consider 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, after the purchases of property, equipment, and other assets, can be used for strategic opportunities, including investing in our business, making strategic acquisitions, and strengthening the balance sheet.

Financial Overview

Revenue

We derive revenue from sales of our products and services. As discussed further in “—Critical Accounting Policies and Estimates—Revenue Recognition” below, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is reasonably assured.

Our total revenue is comprised of the following:

• Product Revenue. The substantial majority of our product revenue is derived from sales of our appliances. Product revenue also includes revenue derived from software licenses of Panorama, Virtual Systems Upgrades, and the VM-Series. We recognize product revenue at the time of shipment, provided that all other revenue recognition criteria have been met. As a percentage of total revenue, we expect our product revenue to vary from quarter to quarter based on seasonal and cyclical factors.

- 39 -

• Services Revenue. Services revenue is derived primarily from Threat Prevention, URL Filtering, GlobalProtect, and WildFire subscriptions and support and maintenance. Our subscriptions are priced as a percentage of the appliance’s list price. Our contractual subscription and support and maintenance terms are typically one to five years. We recognize revenue from subscriptions and support and maintenance over the contractual service period. As a percentage of total revenue, we expect our services revenue to remain at consistent levels or increase over the long term as we introduce new subscriptions, renew existing services contracts, and expand our end-customer base.

Cost of Revenue

Our total cost of revenue consists of cost of product revenue and cost of services revenue. Our cost of revenue includes personnel costs, which consist of salaries, bonuses, and share-based compensation associated with our operations and global customer support organizations. Our cost of revenue also includes allocated costs, which consist of certain facilities, depreciation, benefits, recruiting, and information technology costs that we allocate based on headcount.

• Cost of Product Revenue. Cost of product revenue primarily includes costs paid to our third-party contract manufacturer. Our cost of product revenue also includes product testing costs, allocated costs, warranty costs, shipping costs, and personnel costs associated with logistics and quality control. We expect our cost of product revenue to increase as our product revenue increases.

• Cost of Services Revenue. Cost of services revenue includes personnel costs for our global customer support organization, allocated costs, and URL filtering database service fees. We expect our cost of services revenue to increase as our end-customer base grows.

Gross Margin

Gross margin, or gross profit as a percentage of revenue, has been and will continue to be affected by a variety of factors, including the average sales price of our products, manufacturing costs, the mix of products sold, and the mix of revenue between products and services. For sales of our products, our higher throughput firewall products generally have higher gross margins than our lower throughput firewall products within each product series. For sales of our services, our subscriptions typically have higher gross margins than our support and maintenance. We expect our gross margins to fluctuate over time depending on the factors described above.

Operating Expenses

Our operating expenses consist of research and development, sales and marketing, and general and administrative expense. Personnel costs are the most significant component of operating expenses and consist of salaries, benefits, bonuses, share-based compensation, allocated costs, and with regard to sales and marketing expense, sales commissions. We expect operating expenses to increase in absolute dollars, although they may fluctuate as a percentage of revenue from period to period, as we continue to grow in response to demand for our products and services. As of July 31, 2013, we expect to recognize approximately $133.6 million of share-based compensation expense over a weighted-average period of three years, excluding additional share-based compensation expense related to any future grants of share-based awards. Share-based compensation expense, net of forfeitures, is recognized on a straight-line basis over the requisite service periods of the awards.

• Research and Development. Research and development expense consists primarily of personnel costs. Research and development expense also includes prototype related expenses and allocated costs. We expect research and development expense to increase in absolute dollars as we continue to invest in our future products and services, although our research and development expense may fluctuate as a percentage of total revenue.

• Sales and Marketing. Sales and marketing expense consists primarily of personnel costs including commission costs. We expense commission costs as incurred. Sales and marketing expense also includes costs for market development programs, promotional and other marketing costs, travel costs, office equipment and software, depreciation of capital equipment, professional services, and allocated costs. In the last 12 months, we have significantly increased the size of our sales force and have also substantially grown our sales presence internationally. We expect sales and marketing expense to continue to increase in absolute dollars as we increase the size of our sales and marketing organizations to increase touch points with end-customers and to expand our international presence, although our sales and marketing expense may fluctuate as a percentage of total revenue.

• General and Administrative. General and administrative expense consists of personnel costs as well as professional services. General and administrative personnel include our executive, finance, human resources, and legal organizations. Professional services consist primarily of legal, auditing, accounting, and other consulting costs. We

- 40 -

expect general and administrative expense to increase in absolute dollars due to additional legal costs related to ongoing IP litigation, and additional costs associated with accounting, compliance, insurance, investor relations, and other costs associated with being a public company, although our general and administrative expense may fluctuate as a percentage of total revenue. Refer to the discussion under “Legal Proceedings” included in Part I, Item 3 of this Annual Report on Form 10-K for information related to pending litigation.

Interest Income

Interest income consists of income earned on our cash and cash equivalents and investments. We expect interest income will increase as we grow our cash and investments portfolio depending on our average investment balances during the period, types and mix of investments, and market interest rates.

Other Expense, Net

Other expense, net consists primarily of foreign currency remeasurement gains and losses, foreign currency transaction gains and losses, and the change in the fair value of our convertible preferred stock warrant liability. Convertible preferred stock warrants were classified as a liability on our consolidated balance sheets and remeasured to fair value at each balance sheet date with the corresponding change recorded as other expense. These warrants were exercised during the second quarter of fiscal 2012, and therefore, no charges related to these warrants were incurred after that date. We expect other expense to fluctuate depending on foreign exchange rate movements.

Provision for Income Taxes

Provision for income taxes consists primarily of federal and state income taxes in the United States, income taxes in foreign jurisdictions in which we conduct business, and foreign withholding taxes. We maintain a full valuation allowance for domestic deferred tax assets, including net operating loss carryforwards and research and development and other tax credits. We expect the provision for income taxes to increase in absolute dollars in future years.

We have reorganized our corporate structure and intercompany relationships to more closely align with the international nature of our business activities. This corporate structure may cause volatility to our overall effective tax rate in the short term but is expected to reduce our overall effective tax rate over the long term through changes in international procurement and sales operations.

Product revenue increased$69.2 million, or 39.7%, for fiscal 2013 compared to fiscal 2012. Approximately two-thirds of the increase was driven by our newly introduced PA-3000 Series firewalls and M-100 management appliance. The remaining increase was driven by a greater than 50% increase in product unit volume attributable to sales of our PA-5000 Series and PA-200 firewalls.

Service revenue increased$71.7 million, or 88.9%, for fiscal 2013 compared to fiscal 2012. Approximately half of the increase was related to support and maintenance as a result of an increase in total end-customers to more than 13,500 at July 31, 2013 from more than 9,000 at July 31, 2012. The remaining increase was due to an increase in subscriptions from new and existing

end-customers. The relative increases in revenue from subscriptions and support and maintenance will fluctuate over time, depending on the mix of services revenue and the introduction of new services offerings.

With respect to geographic theaters, the Americas contributed the largest portion of the increase in revenue for fiscal 2013 compared to fiscal 2012 due to its larger and more established sales force compared to our other theaters. Revenue from both EMEA and APAC increased during fiscal 2013 compared to fiscal 2012 due to our investment in increasing the size of our sales force and number of partners in these theaters.

Product cost increased $18.8 million, or 42.1%, for fiscal 2013 compared to fiscal 2012 due to an increase in product unit volume, including sales of our newly introduced PA-3000 Series firewalls and M-100 management appliance.

Service cost increased $20.4 million, or 78.7%, for fiscal 2013 compared to fiscal 2012 due to an increase in personnel costs of $9.5 million, including share-based compensation of $2.9 million. The remaining increase was attributable to other costs incurred to expand our customer service capabilities to support our growing end-customer base.

 Gross margin for fiscal 2013 remained consistent with fiscal 2012. The decrease of 40 basis points in product margin was due to an 80 basis point decrease as a result of the introduction of our PA-3000 Series firewalls, WF-500 appliance and our M-100 management appliance, which will have lower product margins until volume and related cost savings increase, partially offset by decreases in manufacturing costs for other appliances. The increase of 180 basis points in services margin was due to an increase in subscription, support and maintenance without a proportionate increase in our global customer service organization costs. The mix in services revenue was largely unchanged on a period over period basis.

Research and development expense increased$23.9 million, or 62.0%, for fiscal 2013 compared to fiscal 2012 due to an increase in personnel costs of $16.1 million related to increasing our headcount and share-based compensation, an increase in allocated costs of $3.7 million, and an increase in development costs of $2.8 million to support continued investment in our future product and service offerings.

Sales and marketing expense increased$83.9 million, or 72.3%, for fiscal 2013 compared to fiscal 2012 due to an increase in personnel costs of $58.0 million largely due to an increase in headcount, share-based compensation, and commission costs, an increase in allocated costs of $10.7 million, and an increase in marketing activity of $5.6 million related to demand generation activities, trade shows, and other marketing activities. The remaining increase was due to an increase in travel and entertainment costs of $5.6 million, professional service costs of $2.0 million, and office equipment and software costs of $1.9 million in support of our sales efforts.

General and administrative expense increased$16.5 million, or 63.0%, for fiscal 2013 compared to fiscal 2012 due to an increase in professional services costs of $6.9 million, including expenses related to ongoing IP litigation with Juniper of $3.6 million. We expect that these litigation expenses will increase in fiscal 2014 as we approach the February 2014 trial date. The remaining increase was due to an increase in personnel costs of $6.6 million, and an increase in allocated costs of $2.3 million related to overall growth to support the business and building our infrastructure to meet the regulatory requirements of being a public company.

Other expense, net consisted primarily of foreign currency remeasurement losses for fiscal 2013 and the change in fair value of our preferred stock warrant liability for fiscal 2012. The decrease in other expense, net was due to the elimination of the expense related to preferred stock warrant liability as a result of exercise of these warrants by the holders in December 2011 and January 2012, partially offset by an increase in foreign currency remeasurement loss.

We recorded an income tax provision for fiscal 2013 due to U.S. federal income taxes, state income taxes, foreign income taxes, and foreign withholding taxes. We have a valuation allowance for our domestic deferred tax assets. The provision for income taxes increased for fiscal 2013 compared to fiscal 2012 due to a significant increase in domestic taxable income after full utilization of federal net operating loss carryforwards.  In addition, our global operations and foreign presence expanded year over year giving rise to additional foreign income taxes and foreign withholding taxes.

During the fourth quarter of fiscal 2013, we completed the reorganization of our corporate structure and intercompany relationships to more closely align with the international nature of our business activities. Our corporate structure may cause volatility to our overall effective tax rate in the short term but is expected to reduce our overall effective tax rate over the long term through changes in international procurement and sales operations.

Product revenue increased$89.7 million, or 105.7%, for fiscal 2012 compared to fiscal 2011. The increase was primarily driven by an aggregate increase of more than 75% in product unit volume and the introduction of our higher-end PA-5000 Series as opposed to increases in the average selling prices of our other products, which remained relatively flat.

Service revenue increased$46.9 million, or 138.7%, for fiscal 2012 compared to fiscal 2011. The increase was primarily driven by new end-customers and, to a lesser extent, additional sales of subscription services to our existing end-customer base. Our total number of end-customers increased to over 9,000 at July 31, 2012 from approximately 4,700 at July 31, 2011.

With respect to geographic theaters, the Americas contributed the largest portion of the increase in revenue for fiscal 2012 compared to fiscal 2011 due to its larger and more established sales force compared to our other theaters.

 Gross margin decreased50 basis points for fiscal 2012 compared to fiscal 2011. The increase of 10 basis points in product margin was primarily due to an increase in sales volume as opposed to changes in average selling prices of our hardware on a per unit basis. This increase in margin was partially offset by the impact of introducing our PA-200, which is a lower throughput firewall product. On average, margins for firewall products with lower throughput are less than firewall products with higher throughput. The decrease of 110 basis points in services margin was primarily due to a decrease in average margins on revenue from support and maintenance as a result of an increase in personnel and other costs to support our expanding end-customer base, partially offset by higher margin subscriptions sales, while the mix in services revenue was largely unchanged on a period over period basis.

Research and development expense increased$17.2 million, or 80.5%, for fiscal 2012 compared to fiscal 2011, primarily due to an increase in personnel costs of $11.6 million as we increased our headcount to support continued investment in our future product and service offerings and an increase in allocated costs and development costs of $4.4 million.

Sales and marketing expense increased$53.7 million, or 86.2%, for fiscal 2012 compared to fiscal 2011, primarily due to an increase in personnel costs of $30.6 million due to an increase in headcount and commissions. Additionally, marketing activity increased $7.1 million related to trade shows and conventions and marketing development programs, travel costs increased $5.0 million, and allocated costs increased $4.6 million. The remaining increase was due to increases in depreciation, facilities costs, and professional services costs.

General and administrative expense increased$13.1 million, or 99.9%, for fiscal 2012 compared to fiscal 2011, primarily due to an increase in personnel costs of $6.0 million and an increase in professional services costs of $5.2 million primarily related to overall growth to support the business and infrastructure building in preparation for being a public company.

Other expense, net	$	1,110	$	1,651	$	(541	)	(32.8	)%

The change in other expense, net was due to the increase in fair value of the preferred stock warrant liability during fiscal 2012 compared to fiscal 2011. In December 2011 and January 2012, these preferred stock warrants were exercised by the holders. As a result, we issued 197,000 shares of Series A redeemable convertible preferred stock and 24,000 shares of Series B redeemable convertible preferred stock, all of which converted to common stock at the time of our initial public offering (IPO). The amount for fiscal 2012 represents the change in fair value of the preferred stock warrant liability from the beginning of the period to the dates of exercise of the warrants. We do not expect to incur expenses related to these warrants in future periods.

We incurred tax expense for fiscal 2012, primarily due to foreign taxes, state income taxes, and U.S. federal alternative minimum tax. We have a full valuation allowance for our domestic deferred tax assets. The increase in the provision for fiscal 2012 compared to fiscal 2011 was primarily due to an increase in state income taxes, U.S. federal alternative minimum tax, and foreign taxes as a result of an increase in our taxable income.

At July 31, 2013, our cash and cash equivalents and investments of $436.9 million were held for working capital purposes, of which approximately $27.2 million was held outside the United States and not presently available to fund domestic operations and obligations. If we were to repatriate cash held outside the United States, it could be subject to U.S. income taxes, less any previously paid foreign income taxes.

We believe that our cash flow from operations with 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 products and services offerings, the costs to ensure access to adequate manufacturing capacity, 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 or at all. If we are unable to raise additional capital when desired, our business, operating results, and financial condition would be adversely affected.

Operating Activities

Our primary source of cash from operating activities has been from cash collections from our customers. We expect cash inflows from operating activities to be affected by increases in sales and timing of collections. Our primary uses of cash from operating activities have been for personnel costs and purchases from our contract manufacturer. We expect cash outflows from operating activities to be affected by increases in sales and increases in personnel costs as we grow our business. Cash provided by operating activities for fiscal 2013, fiscal 2012, and fiscal 2011 was $114.5 million, $77.4 million, and $32.1 million, respectively.

- 48 -

For fiscal 2013, operating activities provided $114.5 million in cash as a result of our net loss of $29.2 million, non-cash charges of $49.0 million and a net change of $94.7 million in our net operating assets and liabilities. Non-cash charges included share-based compensation, depreciation and amortization, amortization of investment premiums, net of accretion of purchase discounts, and excess tax benefit from share-based compensation. The net change in our net operating assets and liabilities was due to a $113.4 millionincrease in deferred revenue as a result of increases in sales of subscriptions and support and maintenance, a $26.2 millionincrease in accrued compensation and other liabilities as a result of increases in personnel expense and business activity, and a $5.8 millionincrease in accounts payable due to payment timing, partially offset by a $41.8 millionincrease in accounts receivable due to an increase in sales, in particular, increases in sales volume near the end of the period and sales of multi-year subscription and support and maintenance services, and a $8.9 millionincrease in prepaid expenses and other assets. Current deferred revenue increased78.4% from $86.3 million as of July 31, 2012 to $153.9 million as of July 31, 2013. The increase was due to an increase in business volume during the period. Non-current deferred revenue increased92.4% from $49.5 million as of July 31, 2012 to $95.3 million as of July 31, 2013. The increase was due to a higher proportion of sales of multi-year subscriptions and support and maintenance. Our day’s sales outstanding, or DSO, defined as the number of days it takes to turn our average quarterly accounts receivable into cash based on a 90 day average, was 72 days for the quarter ended July 31, 2013, which reflected an increase in accounts receivable for the reasons described above.

For fiscal 2012, operating activities provided $77.4 million in cash as a result of net income of $0.7 million, non-cash charges of $20.7 million, and a net change of $55.9 million in our net operating assets and liabilities. The net change in our net operating assets and liabilities was primarily due to a $68.6 million increase in deferred revenue as a result of increases in sales of subscriptions and support and maintenance, partially offset by a $16.0 million increase in accounts receivable and an $11.1 million increase in prepaid expenses and other assets. Our day’s sales outstanding, or DSO, defined as the number of days it takes to turn our average quarterly accounts receivable into cash based on a 90 day average, was 50 days for the quarter ended July 31, 2012.

For fiscal 2011, operating activities provided $32.1 million in cash, primarily as a result of a net loss of $12.5 million, offset by non-cash charges of $8.5 million as well as a net change of $36.1 million in our net operating assets and liabilities. Non-cash charges included share-based compensation, depreciation and amortization, and the change in fair value of our preferred stock warrant liability. The net change in our operating assets and liabilities was primarily the result of a $43.1 million increase in deferred revenue as a result of increases in sales of subscriptions and support and maintenance and a $9.1 million increase in accrued compensation and other liabilities primarily due to deferred rent related to moving our headquarters from Sunnyvale, California to Santa Clara, California. These increases were partially offset by a $15.4 million increase in accounts receivable due to an increase in sales and a $5.1 million increase in prepaid expenses and other assets as a result of growth in our business. Our DSO was 57 days for the quarter ended July 31, 2011.

Investing Activities

Our investing activities have consisted of purchases of property, equipment, and other assets and purchases, sales, and maturities of investments. We expect to continue such activities as our business grows.

For fiscal 2013, cash used in investing activities was $151.6 million, as a result of $345.3 million in purchases of short-term and long-term investments to shift the mix of investments from money market funds to higher yield corporate notes and bonds and U.S. government agency securities, and capital expenditures to purchase property, equipment, and other assets of $22.4 million, partially offset by proceeds from sales and maturities of investments of $216.2 million.

Cash used in investing activities for fiscal 2012 and 2011, was $14.6 million and $13.0 million, respectively, and was primarily the result of capital expenditures to purchase property and equipment, including $7.0 million for fiscal 2012 related to purchases of demonstration units for use by our customers in evaluating our products and services and capitalized internally developed software costs related to the implementation of our enterprise resource planning system and $7.3 million for fiscal 2011 related to moving our headquarters from Sunnyvale, California to Santa Clara, California.

Financing Activities

Our financing activities have consisted of proceeds from the sale of our common stock in our IPO proceeds from the exercises of stock options and the employee stock purchase plan.

For fiscal 2013, financing activities provided $25.0 million in cash, as a result of proceeds from the exercises of stock options and the employee stock purchase plan of $21.0 million and excess tax benefit from share-based compensation of $6.8 million, partially offset by payments of costs related to our IPO of $2.7 million.

- 49 -

For fiscal 2012, financing activities provided $219.3 million in cash as a result of net proceeds to us from our IPO and the exercises of stock options. On July 25, 2012, we completed our IPO, in which 7,130,000 shares of common stock were sold to the public (inclusive of 5,617,000 shares of common stock sold by us). The public offering price of the shares sold in the IPO was $42.00 per share. After deducting underwriting discounts and commissions, offering expenses payable by us, and net proceeds received by the selling stockholders, the aggregate net proceeds received by us totaled approximately $215.4 million.

For fiscal 2011, financing activities provided $2.6 million in cash as a result of proceeds from the exercises of stock options.

(4) No amounts related to Financial Accounting Standards Board Accounting Standard Codification Topic 740-10, Income Taxes, are included. As of July 31, 2013, we had approximately $2.4 million of tax liabilities recorded related to uncertainty in income tax positions.

Off-Balance Sheet Arrangements

Through July 31, 2013, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities, that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

The critical accounting policies requiring estimates, assumptions, and judgments that we believe have the most significant impact on our consolidated financial statements are described below.

Revenue Recognition

We generate revenue from the sales of hardware and software products, subscriptions, support and maintenance, and other services primarily through a direct sales force and indirect relationships with channel partners, and, to a lesser extent, directly to end-customers.

Revenue is recognized when all of the following criteria are met:

- 50 -

• Persuasive Evidence of an Arrangement Exists. We rely upon non-cancelable sales agreements and purchase orders to determine the existence of an arrangement.

• Delivery has Occurred. We use shipping documents or transmissions of product or service contract registration codes to determine delivery.

• The Fee is Fixed or Determinable. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction.

• Collectability is Reasonably Assured. We assess collectability based on credit analysis and payment history.

We recognize product revenue at the time of shipment provided that all other revenue recognition criteria have been met. Our partners generally receive an order from an end-customer prior to placing an order with us. In addition, payment from our partners is not contingent on the partner’s success in sales to end-customers. Our partners generally do not stock appliances and only have limited stock rotation rights and no price protection rights. When necessary, we make certain estimates and maintain allowances for sales returns and other programs based on our historical experience. These estimates involve inherent uncertainties and management’s judgment. If actual results deviate significantly from our estimates, our revenue could be adversely affected. We recognize services revenue from subscriptions and support and maintenance ratably over the contractual service period, which is typically one to five years. Other services revenue is recognized as the services are rendered and has not been significant to date.

Most of our arrangements, other than renewals of subscriptions and support and maintenance, are multiple-element arrangements with a combination of hardware, software, subscriptions, support and maintenance, and other services. Products and services generally qualify as separate units of accounting. Our hardware deliverables typically include proprietary operating system software, which together deliver the essential functionality of our products. For multiple-element arrangements, we allocate revenue to each unit of accounting based on an estimated selling price at the arrangement inception. The estimated selling price for each element is based upon the following hierarchy: vendor-specific objective evidence (VSOE) of selling price, if available, third-party evidence (TPE) of selling price, if VSOE of selling price is not available, or best estimate of selling price (BESP), if neither VSOE of selling price nor TPE of selling price are available. The total arrangement consideration is allocated to each separate unit of accounting using the relative estimated selling prices of each unit based on the aforementioned selling price hierarchy. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting any specified performance conditions.

To determine the estimated selling price in multiple-element arrangements, we establish VSOE of selling price using the prices charged for a deliverable when sold separately. If VSOE of selling price cannot be established for a deliverable, we establish TPE of selling price by evaluating similar and interchangeable competitor products or services in standalone arrangements with similarly situated partners. However, as our products contain a significant element of proprietary technology and offer substantially different features and functionality from our competitors, we are unable to obtain comparable pricing of our competitors’ products with similar functionality on a standalone basis. Therefore, we have not been able to obtain reliable evidence of TPE of selling price. If neither VSOE nor TPE of selling price can be established for a deliverable, we establish BESP primarily based on historical transaction pricing. Historical transactions are segregated based on our pricing model and our go-to-market strategy, which include factors such as type of sales channel (reseller, distributor, or end-customer), the geographies in which our products and services were sold (domestic or international), offering type (products or services), and whether or not the opportunity was identified by our sales force or by our partners. In analyzing historical transaction pricing, we evaluate whether a majority of the prices charged for a product or service, as represented by a percentage of list price, fall within a reasonable range. To further support the best estimate of selling price as determined by the historical transaction pricing or when such information is unavailable, such as when there are limited sales of a new product or service, we consider the same factors we have established through our pricing model and go-to-market strategy. The determination of BESP is made through consultation with and approval by our management. In determining BESP, we rely on certain assumptions and apply significant judgment. As our business offerings evolve over time, we may be required to modify our estimated selling prices in subsequent periods, and our revenue could be adversely affected.

In multiple-element arrangements where software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative estimated selling prices of each of the deliverables in the arrangement based on the aforementioned estimated selling price hierarchy. The arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the residual method when VSOE of fair value of the undelivered items exists. Under the residual method, the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. In determining VSOE of fair value, we evaluate whether a substantial majority of the historical prices charged for a product or service sold on a standalone basis, as represented by a percentage of list price, fall within a reasonably narrow range. If VSOE of fair value of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and

- 51 -

recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless support and maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual service period.

Share-Based Compensation

Compensation expense related to share-based transactions, including employee and non-employee director awards, is measured and recognized in the financial statements based on fair value. The fair value of option awards and purchases under our 2012 Employee Stock Purchase Plan (2012 ESPP) is estimated on the grant date. The fair value of restricted stock units (RSUs) is based on the closing market price of our common stock on the date of grant. The share-based compensation expense, net of forfeitures, is recognized using a straight-line basis over the requisite service periods of the awards. We estimate a forfeiture rate to calculate the share-based compensation expense for our awards. Our forfeiture rate is based on an analysis of our actual historical forfeitures.

The fair value of options and shares sold through our 2012 ESPP is determined using the Black-Scholes option-pricing model. Our option-pricing model requires the input of the fair value of our common stock and other subjective assumptions, including the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and the expected dividend yield of our common stock. The assumptions used in our option-pricing model represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our share-based compensation expense could be materially different in the future.

In addition to assumptions used in the Black-Scholes option-pricing model, we must also estimate a forfeiture rate to calculate the share-based compensation expense for our awards. Quarterly changes in the estimated forfeiture rate can have a significant impact on our share-based compensation expense as the cumulative effect of adjusting the rate is recognized in the period the forfeiture estimate is changed. If a revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the share-based compensation expense recognized in the financial statements. If a revised forfeiture rate is lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase to the share-based compensation expense recognized in the financial statements.

We will continue to use judgment in evaluating the assumptions related to our share-based compensation expense on a prospective basis. As we continue to accumulate additional data, we may have refinements to our estimates, which could materially impact our future share-based compensation expense.

Income Taxes

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires us to estimate and measure the tax liability as the largest amount that is more likely than not to be realized upon ultimate settlement.

Significant judgment is also required in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe our reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historical income tax provisions and accruals. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences may impact the provision for income taxes in the period in which such determination is made.

- 52 -

Estimates of future taxable income are based on assumptions that are consistent with our plans. Assumptions represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. Should actual amounts differ from our estimates, the amount of our tax expense and liabilities could be materially impacted.

Contract Manufacturer Liabilities

We outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturer and payments to it are a significant portion of our product cost of revenues. We have employees in our manufacturing and operations organization who manage our relationship with our independent contract manufacturer, manage our supply chain, and monitor product testing and quality. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturer to us and immediately to our partners upon shipment. Our independent contract manufacturer assembles our products using design specifications, quality assurance programs, and standards that we establish, and it procures components and assembles our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, which may be caused by factors outside of our control, we accrue for costs for manufacturing commitments in excess of our forecasted demand including costs for excess components or for carrying costs incurred by our contract manufacturer, which could have an adverse impact on our gross margins and profitability. To date, we have not accrued significant costs associated with this exposure.

Loss Contingencies

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the likelihood of loss or impairment of an asset, or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. If we determine that a loss is possible and the range of the loss can be reasonably determined, then we disclose the range of the possible loss. We regularly evaluate current information available to us to determine whether an accrual is required, an accrual should be adjusted or a range of possible loss should be disclosed.

From time to time, we are involved in disputes, litigation, and other legal actions. We are vigorously defending our current litigation matters. However, there are many uncertainties associated with any litigation, and these actions or other third-party claims against us may cause us to incur substantial settlement charges, which are inherently difficult to estimate and could adversely affect our results of operations. The actual liability in any such matters may be materially different from our estimates, which could result in the need to adjust our liability and record additional expenses. Refer to the discussion under “Commitments and Contingencies—Litigation” in Note 6 to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K for information related to pending litigation.

Impairment of Long-Lived Assets

We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets, including property and equipment, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. Through July 31, 2013, our impairment write-down of long-lived assets was not material.

Warranties

We generally provide a one-year warranty on hardware and a three-month warranty on software. We are indemnified by our contract manufacturer for product liability claims arising out of manufacturing defects. We accrue for potential warranty claims as a component of cost of product revenues based on historical experience and other data. Accrued warranty is recorded in accrued liabilities on the consolidated balance sheets and is reviewed periodically for adequacy. If we experience an increase in warranty claims compared with our historical experience, or if the cost of servicing warranty claims is greater than expected, our gross margin could be adversely affected. To date, we have not accrued any significant costs associated with our warranty.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

Our sales contracts are primarily denominated in U.S. dollars. A portion of our operating expenses are incurred outside the United States and are denominated in foreign currencies and are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Euro, British Pound, and Japanese Yen. Additionally, fluctuations in foreign currency exchange rates may cause us to recognize transaction gains and losses in our statement of operations. The effect of an immediate 10% adverse change in foreign exchange rates on monetary assets and liabilities at July 31, 2013 would not be material to our financial condition or results of operations. To date, foreign currency transaction gains and losses and exchange rate fluctuations have not been material to our financial statements, and we have not engaged in any foreign currency hedging transactions.

As our international operations grow, our risks associated with fluctuation in currency rates will become greater, and we will continue to reassess our approach to managing this risk. In addition, currency fluctuations or a weakening U.S. dollar can increase the costs of our international expansion.

Interest Rate Risk

The primary objectives of our investment activities are to preserve principal, provide liquidity, and maximize income without significantly increasing risk. Some of the securities we invest in are subject to interest risk. To minimize this risk, we maintain our portfolio of cash, cash equivalents, and short-term investments in a variety of securities, including commercial paper, money market funds, U.S. government and agency securities, and corporate debt securities. Due to the short duration and conservative nature of our investment portfolio, a movement of 10% in market interest rates would not have a material impact on our operating results and the total value of the portfolio. The effect of an immediate 10% change in interest rates at July 31, 2013 would not have been material to our financial statements assuming consistent investment levels.

The Board of Directors and Stockholders

Palo Alto Networks, Inc.

We have audited the accompanying consolidated balance sheets of Palo Alto Networks, Inc. as of July 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income (loss), redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the three years in the period ended July 31, 2013. 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 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Palo Alto Networks, Inc. at July 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended July 31, 2013, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Palo Alto Networks, Inc.'s internal control over financial reporting as of July 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated September 24, 2013 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Palo Alto Networks, Inc.

We have audited Palo Alto Networks, Inc.'s internal control over financial reporting as of July 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). Palo Alto Networks, Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Palo Alto Networks, Inc. maintained, in all material respects, effective internal control over financial reporting as of July 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Palo Alto Networks, Inc. as of July 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income (loss), redeemable convertible preferred stock and stockholders' equity (deficit), and cash flows for each of the three years in the period ended July 31, 2013 of Palo Alto Networks, Inc. and our report dated September 24, 2013 expressed an unqualified opinion thereon.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management's Report on Internal Control Over Financial Reporting

The management of Palo Alto Networks, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934 for the Company. The Company's internal control over financial reporting is a process designed under the supervision of the Company's principal executive and principal financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

The Company's internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on the Consolidated Financial Statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of July 31, 2013, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework. Based on that assessment, management concluded that, as of July 31, 2013, the Company's internal control over financial reporting was effective.

The effectiveness of the Company's internal control over financial reporting as of July 31, 2013, has been audited by Ernst & Young LLP, the independent registered public accounting firm that audits the Company's Consolidated Financial Statements, as stated in their report preceding this report, which expresses an unqualified opinion on the effectiveness of the Company's internal control over financial reporting as of July 31, 2013.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business and Summary of Significant Accounting Policies

Description of Business

Palo Alto Networks, Inc. (the “Company,” “we,” “us,” or “our”), located in Santa Clara, California, was incorporated in March 2005 under the laws of the State of Delaware and commenced operations in April 2005. We offer a next-generation network security platform that allows enterprises, service providers, and government entities to secure their networks and safely enable the increasingly complex and rapidly growing number of applications running on their networks. The core of our platform is our Next-Generation Firewall that delivers application, user, and content visibility and control integrated within the firewall through our proprietary operating system, hardware, and software architecture. We primarily sell our products and services to end-customers through our channel partners and infrequently directly to end-customers. Our partners are supported by our sales and marketing organization in the Americas, in Europe, the Middle East, and Africa (EMEA), and in Asia Pacific and Japan (APAC).

Basis of Presentation and Consolidation

The accompanying consolidated financial statements, which include the Company and its wholly owned subsidiaries, have been prepared in conformity with U.S. generally accepted accounting principles. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include the best estimate of selling price for our products and services, share-based compensation, future taxable income, contract manufacturer liabilities, litigation and settlement costs and other loss contingencies, and warranty liabilities. We base our estimates on historical experience and also on assumptions that we believe are reasonable. Actual results could differ materially from those estimates.

Concentrations

Financial instruments that subject us to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and accounts receivable. The Company invests only in high-quality credit instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities. Management believes that the financial institutions that hold our investments are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits.

Our accounts receivables are primarily derived from our channel partners representing various geographical locations. We perform ongoing credit evaluations of our channel partners and generally do not require collateral on accounts receivable. We maintain an allowance for doubtful accounts for estimated potential credit losses. As of July 31, 2013, four partners represented 38%, 16%, 11%, and 11% of our gross accounts receivable. For fiscal 2013, three partners represented 30%, 20%, and 14% of our total revenue. We rely on an independent contract manufacturer to assemble all of our products and sole suppliers for a certain number of our components.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Unrealized gains and losses on available-for-sale investments are included in our other comprehensive income or loss.

Foreign Currency Transactions

The functional currency of our foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities denominated in foreign currencies have been remeasured into U.S. dollars using the exchange rates in effect at the balance sheet dates. Foreign currency denominated income and expenses have been remeasured using the average exchange rates in effect during each period. Foreign currency remeasurement gains and losses and foreign currency transaction gains and losses are not significant to the financial statements.

- 65 -

Cash and Cash Equivalents

We consider all highly liquid investments held at financial institutions, such as commercial paper, money market funds, and other money market securities with original maturities of three months or less at date of purchase to be cash equivalents.

Fair Value of Financial Instruments

We define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities, due to their short-term nature.

Investments

We classify our investments as available-for-sale at the time of purchase since it is our intent that these investments are available for current operations, and include these investments on our balance sheet as either short-term or long-term investments depending on their maturity. Investments not considered cash equivalents and with maturities one year or less from the consolidated balance sheet date are classified as short-term investments. Investments with maturities greater than one year from the consolidated balance sheet date are classified as long-term investments.

Investments are considered impaired when a decline in fair value is judged to be other-than-temporary. We consult with our investment managers and consider available quantitative and qualitative evidence in evaluating potential impairment of our investments on a quarterly basis. If the cost of an individual investment exceeds its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and our intent and ability to hold the investment. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each partner’s expected ability to pay, and the collection history with each partner, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. As of July 31, 2013 and 2012, the allowance for doubtful accounts activity was not significant.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally one to seven years. Leasehold improvements are depreciated over the shorter of the estimated useful lives of the improvements or the remaining lease term.

Impairment of Long-Lived Assets

We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets, including property and equipment, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. Through July 31, 2013, our impairment write-down of long-lived assets was not material.

Warranties

We generally provide a one-year warranty on hardware and a three-month warranty on software. We are indemnified by our contract manufacturer for product liability claims arising out of manufacturing defects. We accrue for potential warranty claims as a component of cost of product revenues based on historical experience and other data. Accrued warranty is recorded in accrued

- 66 -

liabilities on the consolidated balance sheets and is reviewed periodically for adequacy. To date, we have not accrued any significant costs associated with our warranty.

Contract Manufacturer Liabilities

We outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturer and payments to it are a significant portion of our product cost of revenues. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturer to us and immediately to our partners upon shipment. Our independent contract manufacturer assembles our products using design specifications, quality assurance programs, and standards that we establish and it procures components and assembles our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, we accrue for costs for contractual manufacturing commitments in excess of our forecasted demand including costs for excess components or for carrying costs incurred by our contract manufacturer. To date, we have not accrued any significant costs associated with this exposure.

Revenue Recognition

We generate revenue from the sales of hardware and software products, subscriptions, support and maintenance, and other services primarily through a direct sales force and indirect relationships with our partners.

Revenue is recognized when all of the following criteria are met:

• Persuasive Evidence of an Arrangement Exists. We rely upon non-cancelable sales agreements and purchase orders to determine the existence of an arrangement.

• Delivery has Occurred. We use shipping documents or transmissions of product or service contract registration codes to determine delivery.

• The Fee is Fixed or Determinable. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction.

•Collectability is Reasonably Assured. We assess collectability based on credit analysis and payment history.

We recognize product revenue at the time of shipment provided that all other revenue recognition criteria have been met. Our partners generally receive an order from an end-customer prior to placing an order with us. In addition, payment from our partners is not contingent on the partner’s success in sales to end-customers. Our partners generally do not stock appliances and only have limited stock rotation rights and no price protection rights. When necessary, we make certain estimates and maintain allowances for sales returns and other programs based on our historical experience. To date, these estimates have not been significant. We recognize services revenue from subscriptions and support and maintenance ratably over the contractual service period, which is typically one to five years. Other services revenue is recognized as the services are rendered and has not been significant to date.

Most of our arrangements, other than renewals of subscriptions and support and maintenance, are multiple-element arrangements with a combination of hardware, software, subscriptions, support and maintenance, and other services. Products and services generally qualify as separate units of accounting. Our hardware deliverables typically include proprietary operating system software, which together deliver the essential functionality of our products. For multiple-element arrangements, we allocate revenue to each unit of accounting based on an estimated selling price at the arrangement inception. The estimated selling price for each element is based upon the following hierarchy: vendor-specific objective evidence (VSOE) of selling price, if available, third-party evidence (TPE) of selling price, if VSOE of selling price is not available, or best estimate of selling price (BESP), if neither VSOE of selling price nor TPE of selling price are available. The total arrangement consideration is allocated to each separate unit of accounting using the relative estimated selling prices of each unit based on the aforementioned selling price hierarchy. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions.

To determine the estimated selling price in multiple-element arrangements, we establish VSOE of selling price using the prices charged for a deliverable when sold separately. If VSOE of selling price cannot be established for a deliverable, we establish TPE of selling price by evaluating similar and interchangeable competitor products or services in standalone arrangements with similarly situated partners. However, as our products contain a significant element of proprietary technology and offer substantially different features and functionality from our competitors, we are unable to obtain comparable pricing of our competitors’ products with similar functionality on a standalone basis. Therefore, we have not been able to obtain reliable evidence of TPE of selling price. If neither VSOE nor TPE of selling price can be established for a deliverable, we establish BESP primarily based on historical transaction

- 67 -

pricing. Historical transactions are segregated based on our pricing model and our go-to-market strategy, which include factors such as type of sales channel (reseller, distributor, or end-customer), the geographies in which our products and services were sold (domestic or international), offering type (products or services), and whether or not the opportunity was identified by our sales force or by our partners. In analyzing historical transaction pricing we evaluate whether a majority of the prices charged for a product or service, as represented by a percentage of list price, fall within a reasonable range. To further support the best estimate of selling price as determined by the historical transaction pricing or when such information is unavailable, such as when there are limited sales of a new product or service, we consider the same factors we have established through our pricing model and go-to-market strategy. The determination of BESP is made through consultation with and approval by our management.

In multiple element arrangements where software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative estimated selling prices of each of the deliverables in the arrangement based on the aforementioned estimated selling price hierarchy. The arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the residual method when VSOE of fair value of the undelivered items exists. Under the residual method, the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. In determining VSOE of fair value, we evaluate whether a substantial majority of the historical prices charged for a product or service sold on a standalone basis, as represented by a percentage of list price, fall within a reasonably narrow range. If VSOE of fair value of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless support and maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual service period.

We account for multiple agreements with a single partner as one arrangement if the contractual terms and/or substance of those agreements indicate that they may be so closely related that they are, in effect, parts of a single arrangement.

Revenues are reported net of sales taxes. Shipping charges billed to partners are included in revenues and related costs are included in cost of revenue. Sales commissions and other incremental costs to acquire contracts are also expensed as incurred. After receipt of a partner order, any amounts billed in excess of revenue recognized are recorded as deferred revenue.

Advertising Costs

Advertising costs, which are expensed and included in sales and marketing expense when incurred, were $1,808,000, $1,604,000, and $757,000 during the years ended July 31, 2013, 2012, and 2011, respectively.

Software Development Costs

Internally developed software includes enterprise-level business software that we are customizing to meet our specific operational needs. We capitalized a total of $4,877,000 and $3,226,000 during the years ended July 31, 2013 and 2012, respectively. These capitalized costs consisted of the external direct costs and the internal payroll and payroll related costs that are related to the implementation of our enterprise resource planning software system and will be amortized over a useful life of five years. Through July 31, 2013, we recognized amortization expense of $978,000.

The costs to develop software that is marketed externally have not been capitalized as we believe our current software development process is essentially completed concurrent with the establishment of technological feasibility. As such, all related software development costs are expensed as incurred and included in research and development expense on the consolidated statements of operations.

Share-Based Compensation

Compensation expense related to share-based transactions, including employee and non-employee director awards, is measured and recognized in the financial statements based on fair value on the grant date. The fair value of restricted stock units (RSUs) is based on the closing market price of our common stock on the date of grant. The fair value of option awards and purchases under the 2012 Employee Stock Purchase Plan (2012 ESPP) is estimated using the Black-Scholes option-pricing model. This model requires the input of the fair value of our common stock and that at the date of grant we determine the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The share-based compensation expense, net of forfeitures, is recognized using a straight-line basis over the requisite service periods of the awards. We estimate a forfeiture rate to calculate the share-based compensation expense for our awards. Our forfeiture rate is based on an analysis of our actual historical forfeitures.

Income Taxes

- 68 -

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.

We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires us to estimate and measure the tax liability as the largest amount that is more likely than not to be realized upon ultimate settlement.

Loss Contingencies

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the likelihood of loss or impairment of an asset, or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. If we determine that a loss is possible and the range of the loss can be reasonably determined, then we disclose the range of the possible loss. We regularly evaluate current information available to us to determine whether an accrual is required, an accrual should be adjusted or a range of possible loss should be disclosed.

Recent Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2011-05, Presentation of Comprehensive Income. The standard requires entities to have more detailed reporting of comprehensive income. The guidance was effective for us in the first quarter of fiscal 2013 and applied retrospectively. Our adoption of this guidance did not impact our consolidated financial position, results of operations, or cash flows.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220)-Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires entities to present (either on the face of the income statement or in the notes) the effects on the line items of the income statement for amounts reclassified out of accumulated other comprehensive income. The guidance is effective for us in the first quarter of fiscal 2014 and should be applied prospectively. Early adoption is permitted. We believe that adoption of this guidance will not have a material impact on our consolidated financial position, results of operations, or cash flows.

2. Fair Value Measurements

We categorize assets and liabilities recorded at fair value on our consolidated balance sheets based upon the level of judgment associated with inputs used to measure their fair value. The categories are as follows:

• Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

• Level 3—Inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

Unrealized losses related to these investments are due to interest rate fluctuations as opposed to changes in credit quality. In addition, we do not intend to sell and it is not more likely than not that we would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. As a result, there is no other-than-temporary impairment for these investments at July 31, 2013.

The amortized cost and fair value of our investments at July 31, 2013, by contractual years-to-maturity, are as follows (in thousands):

6. Commitments and Contingencies

Leases

We lease our facilities under various non-cancelable operating leases, which expire through the year ending July 31, 2023.

In September 2012, we entered into two lease agreements for an aggregate of approximately 300,000 square feet of space in Santa Clara, California to serve as our new corporate headquarters beginning in November 2013. The leases have inception dates of November 2012 and August 2013, expire in July 2023, and allow for two separate five-year options to extend the lease term. Payments under these leases will be approximately $94,400,000 over the lease term. Each lease has a rent holiday, which was included in the determination of rent expense.

In July 2013, we entered into a 51-month sub-lease agreement for our current corporate headquarters with a lease inception date of January 2014. Payments under this sub-lease will be approximately $10,700,000 over the lease term. The sub-lease agreement contains a rent credit of $524,000, which was included in the determination of rental income.

Rent expense was $4,356,000, $2,258,000, and $1,393,000 for the years ended July 31, 2013, 2012 and 2011, respectively. Rent expense is recognized using the straight-line method over the term of the lease.

The aggregate future non-cancelable minimum rental payments on our operating leases, as of July 31, 2013, are as follows (in thousands):

Contract Manufacturer Commitments

Our independent contract manufacturer procures components and assembles our products based on our forecasts. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and product marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate supply, we may issue forecasts and orders for components and products that are non-cancelable. Obligations under contracts that we can cancel without a significant penalty are not included. As of July 31, 2013, we had $19,130,000 of open orders.

Litigation

In December 2011, Juniper Networks, Inc. filed a complaint against us in the United States District Court for the District of Delaware alleging patent infringement. The complaint seeks preliminary and permanent injunctions against infringement, treble damages, and attorney’s fees. On February 9, 2012, we filed a response to the complaint, which denied all claims and asserted that the claimant’s patents were invalid. On February 28, 2012, Juniper filed a motion to strike our defense of invalidity based on the legal doctrine of “assignor estoppel.” On March 23, 2012, we filed a brief in opposition to that motion. Juniper filed a brief in response on April 2, 2012. On August 2, 2012, the District Court issued an order granting Juniper’s motion as to one of the patents in suit (the ’634 patent) but denying Juniper’s motion as to the five other patents in suit. On September 4, 2012, Juniper filed a motion to amend its complaint to allege that our appliances infringe two additional U.S. patents but also to withdraw its allegations as to a previously-asserted patent. This amended complaint was officially filed on September 25, 2012, pursuant to a stipulation between the parties. Juniper now alleges that our appliances infringe seven of its patents. On September 13, 2012, we filed with the U.S. Patent and Trademark Office requests for inter partes reexamination of five of the six patents asserted by Juniper in its original complaint. We did not file a request for reexamination on the withdrawn patent. On October 12, 2012, we filed an answer to Juniper’s amended complaint, which denied that we infringed Juniper’s patents and asserted that Juniper’s patents were invalid. On October 19 and December 3, 2012, the U.S. Patent and Trademark Office granted our requests for reexamination for three patents, rejecting a number of the claims asserted in the litigation, and on November 15 and 26, 2012, the U.S. Patent and Trademark Office denied our requests for reexamination as to two other patents. We have the opportunity to seek review of these denials within the U.S. Patent and Trademark Office. Each party served its opening expert report on April 12, 2013, and rebuttal expert report on May 13, 2013, and supplemental expert reports on June 11, 2013. The parties filed opening and responsive briefs regarding claim construction, filed their opening summary judgment briefs on August 20, 2013, and filed opposition briefs and additional summary judgment motions on September 12, 2013. On June 20, 2013 and July 23, 2013, we filed with the U.S. Patent and Trademark Office petitions for inter partes review for two other patents asserted by Juniper in the litigation. The Patent and Trademark Office has not yet ruled on those petitions. A hearing to resolve claim construction issues, as well as motions for summary judgment, is scheduled to be heard on November 15, 2013.

A trial date has been scheduled for February 24, 2014, and we are vigorously defending ourselves from such claims. At this stage in the litigation we do not believe that a loss is probable and we are unable to estimate a possible loss or range of possible loss.

In addition to the above matter, we are subject to legal proceedings, claims, and litigation arising in the ordinary course of business, including intellectual property litigation. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. We accrue for contingencies when we believe that a loss is probable and that we can reasonably estimate the amount of any such loss. We have made an assessment of the probability of incurring any such losses and whether or not those losses are estimable.

To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred and the amount of such additional loss would be material, we will either disclose the estimated additional loss or state that such an estimate cannot be made.

Indemnification

Under the indemnification provisions of our standard sales related contracts, we agree to defend our end-customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Our exposure under these indemnification provisions is generally limited to the total amount paid by our end-customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. In addition, we indemnify our officers, directors, and certain key employees while they are serving in good faith in their company capacities. To date, there have been no claims under any indemnification provisions.

7. Stockholders’ Equity (Deficit)

- 73 -

In July 2012, we completed our initial public offering whereby 6,200,000 shares of common stock were sold to the public at a price of $42.00 per share. We sold 4,687,000 common shares and selling stockholders sold 1,513,000 common shares. In connection with the exercise of the underwriters’ over-allotment option, 930,000 additional shares of common stock were sold to the public at the initial offering price of $42.00 per share. We received aggregate proceeds of $219,400,000 from the initial public offering and the underwriters’ over-allotment option, net of underwriters’ discounts and commissions, but before deducting offering expenses of approximately $4,000,000. As of July 31, 2012 unpaid offering expenses have been accrued against the proceeds and are presented as a reduction of proceeds from our initial public offering, net of offering costs in the consolidated financial statements. Upon the closing of the initial public offering, all shares of our outstanding redeemable convertible preferred stock automatically converted into 41,305,000 shares of common stock.

In October 2012, we completed our secondary offering whereby certain stockholders of our company sold 4,800,000 shares of common stock to the public at a price of $63.00 per share. The aggregate offering price for shares sold in the offering was approximately $290,304,000, net of underwriting discounts and commissions. We did not receive any proceeds from the sale of shares in this offering. Offering expenses were paid by the stockholders who sold shares of common stock in the offering.

8. Equity Award Plans

Share-Based Compensation Plans

2012 Equity Incentive Plan

Our 2012 Equity Incentive Plan (2012 Plan) was adopted by our board of directors and approved by the stockholders on June 5, 2012 and was effective one business day prior to the effectiveness of our registration statement for our initial public offering. The 2012 Plan replaced our 2005 Equity Incentive Plan (2005 Plan). Our 2012 Plan provides for the granting of stock options, restricted stock awards, RSUs, stock appreciation rights, performance units, and performance shares to our employees, directors, and consultants.

Awards granted under our 2012 Plan vest over the periods determined by the board of directors, generally four years, and expire no more than ten years after the date of grant. In the case of an incentive stock option granted to an employee, who at the time of grant, owns stock representing more than 10% of the total combined voting power of all classes of stock, the exercise price shall be no less than 110% of the fair value per share on the date of grant, and expire five years from the date of grant, and for options granted to any other employee, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. In the case of a non-statutory stock option and options granted to consultants, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. Stock that is purchased prior to vesting is subject to our right of repurchase at any time following termination of the participant.

RSUs generally vest over a period of three to four years from the date of grant. Until vested, RSUs do not have the voting and dividend participation rights of common stock and the shares underlying the awards are not considered issued and outstanding.

A total of 21,205,000 shares of our common stock are reserved for issuance pursuant to the 2012 Plan and includes shares that are (i) reserved but unissued under the 2005 Plan on the effective date of the 2012 Plan or (ii) returned to our 2005 Plan as a result of expiration or termination of options. On the first day of each fiscal year, starting with August 1, 2013, the number of shares in the reserve will increase by the lesser of (i) 8,000,000 shares, (ii) 4.5% of the outstanding shares of common stock on the last day of our immediately preceding fiscal year, or (iii) such other amount as determined by our board of directors.

2012 Employee Stock Purchase Plan

Our 2012 ESPP was adopted by our board of directors and approved by the stockholders on June 5, 2012 and was effective upon completion of our initial public offering.

The 2012 ESPP permits eligible employees to acquire shares of our common stock at 85% of the lower of the fair market value of our common stock on the first trading day of each offering period or on the exercise date. Each offering period will be approximately six months starting on the first trading date on or after March 15 and September 15 of each year, except for the first offering period, which commenced on July 19, 2012 and ended on March 15, 2013. Participants may purchase shares of common stock through payroll deductions of up to 15% of their eligible compensation, subject to purchase limits of 625 shares during a six month period or $25,000 worth of stock for each calendar year.

A total of 829,000 shares of our common stock are available for sale under the 2012 ESPP as of July 31, 2013. On the first day of each fiscal year, starting with August 1, 2013, the number of shares in the reserve will increase by the lesser of (i) 2,000,000 shares,

- 74 -

(ii) 1% of the outstanding shares of our common stock on the first day of the fiscal year, or (iii) such other amount as determined by our board of directors.

2005 Plan

Our 2005 Plan was terminated upon the completion of our initial public offering. Awards that were outstanding upon termination remained outstanding pursuant to their original terms.

Employee Stock Purchase Plan

During the years ended July 31, 2013 and 2012, compensation expense recognized in connection with the 2012 Employee Stock Purchase Plan (2012 ESPP) was $5,263,000 and $172,000, respectively. Employees purchased approximately 170,000 shares of common stock at an average exercise price of $36.72 during the year ended July 31, 2013.

Share-Based Compensation

We record share-based compensation awards based on fair value as of the grant date. For option awards and ESPP purchases we use the Black-Scholes option-pricing model to determine fair value. We recognize such costs to compensation expense on a straight-line basis over the employee’s requisite service period. The assumptions for our option-pricing model are determined as follows:

Fair Value of Common Stock

Prior to our initial public offering, our board of directors considered numerous objective and subjective factors to determine the fair value of our common stock at each meeting at which awards were approved. These factors included, but were not limited to (i) contemporaneous third-party valuations of common stock; (ii) the rights and preferences of convertible preferred stock relative to common stock; (iii) the lack of marketability of common stock; (iv) developments in the business; and (v) the likelihood of achieving a liquidity event, such as an initial public offering or sale of the Company, given prevailing market conditions.

Risk-Free Interest Rate

We base the risk-free interest rate used in the Black-Scholes valuation model on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term of the options for each option group.

Expected Term

The expected term represents the period that our share-based awards are expected to be outstanding. We determined the expected term assumption based on the contractual term of the awards adjusted for estimates of our employees' expected exercise and expected post-vesting termination behavior.

Volatility

We determine the price volatility factor based on the historical volatilities of our peer group as we do not have sufficient trading history for our common stock.

Dividend Yield

The expected dividend assumption is based on our current expectations about our anticipated dividend policy.

- 76 -

The following table summarizes the assumptions relating to our stock options:

	Year Ended July 31,
	2013	2012	2011
Risk-free interest rate	1.0%	0.7% - 1.1%	0.8% - 1.8%
Expected term	6 years	4 – 6 years	4 years
Volatility	50%	49% – 51%	49%
Dividend yield	—%	—%	—%

The following table summarizes the assumptions related to the 2012 ESPP:

	Year Ended July 31,
	2013	2012
Risk-free interest rate	0.1%	0.1%
Expected term	< 1 year	< 1 year
Volatility	42%	46%
Dividend yield	—%	—%

Share-based compensation expense is included in costs and expenses as follows (in thousands):

	Year Ended July 31,
	2013		2012		2011
Cost of revenue	$	4,351	$	774	$	206
Research and development	9,931		3,733		1,020
Sales and marketing	20,493		4,267		1,133
General and administrative	9,101		5,151		2,374
Total	$	43,876	$	13,925	$	4,733

For fiscal 2013, we modified the terms of certain share-based awards for a former employee and as a result, we recorded $1,861,000 of compensation expense within sales and marketing expense.

For fiscal 2012, we modified the terms of certain share-based awards for a former employee and as a result, we recorded $854,000 of compensation expense within research and development expense.

For fiscal 2011, we modified the terms of certain share-based awards for a former employee and as a result, we recorded $1,626,000 of compensation expense within general and administrative expense.

At July 31, 2013, total compensation cost related to unvested share-based awards granted to employees under our stock plans but not yet recognized was $133,563,000, net of estimated forfeitures. This cost is expected to be amortized on a straight-line basis over a weighted-average period of three years. Future grants will increase the amount of compensation expense to be recorded in these periods.

Deferred tax assets:
Accruals and reserves	$	23,461		$	12,065

Total	$	356		$	9

A valuation allowance is provided when it is more likely than not that the deferred tax asset will not be realized. Realization of the deferred tax assets is dependent upon future taxable income, if any, the amount and timing of which are uncertain. At such time, if it is determined that it is more likely than not that the deferred tax assets are realizable, the valuation allowance will be adjusted. As of July 31, 2013, we have provided a valuation allowance for our federal and state deferred tax assets that we believe are more likely than not unrealizable. The net valuation allowance increased by approximately $8,104,000 during fiscal 2013. As of July 31, 2013, we had federal and state net operating loss carryforwards of approximately nil and $37,363,000, respectively, available to reduce future taxable income, if any. If not utilized, the state net operating loss carryforwards will begin to expire from the years ending July 31, 2017 through 2030.

- 78 -

We also have federal and state research and development tax credit carryforwards of approximately $100,000 and $4,577,000, respectively. If not utilized, the federal credit carryforwards will expire in various amounts from the years ended July 31, 2026 through 2033. The state credit will carry forward indefinitely.

Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

We use the with-and-without approach described in guidance which has been incorporated into ASC 740 Income Taxes to determine the recognition and measurement of excess tax benefits. Accordingly, we have elected to recognize excess income tax benefits from share-based awards in additional paid-in capital only if an incremental income tax benefit would be realized after considering all other tax attributes presently available to us. As of July 31, 2013, the amount of excess tax benefits from stock options included in federal and state net operating losses is $63,915,000 and $112,377,000, respectively. The impact of this excess tax benefit is recognized as additional paid-in capital when it reduces taxes payable. In addition, we have elected to account for the indirect effects of share-based awards on other tax attributes, such as the research, foreign and other tax credits, through the consolidated statement of operations.

As of July 31, 2013, we had $6,561,000 of unrecognized tax benefits, all of which would affect income tax expense if recognized, before consideration of our valuation allowance. As of July 31, 2013, our federal, state, and foreign returns for the tax years 2008 through the current period are still open to examination. We do not expect the unrecognized tax benefits to change significantly over the next 12 months. We recognize both interest and penalties associated with uncertain tax positions as a component of income tax expense. As of July 31, 2013 and 2012, we recognized interest and penalties of $294,000 and $72,000, respectively. The ultimate amount and timing of any future cash settlements cannot be predicted with reasonable certainty.

A reconciliation of the gross unrecognized tax benefit is as follows (in thousands):

	Year Ended July 31,
	2013			2012		2011
Unrecognized tax benefits at the beginning of the period	$	2,630		$	1,972	$	1,061

Lapse of statute of limitations	—			—		—
Unrecognized tax benefits at the end of the period	$	6,561		$	2,630	$	1,972

As of July 31, 2013, we have not made any tax provision for U.S. federal and state income taxes on approximately $5,208,000 of undistributed earnings in foreign subsidiaries, which we expect to reinvest outside of the U.S. indefinitely. If we were to repatriate these earnings to the U.S., we would be subject to U.S. income taxes, an adjustment for foreign tax credits, and foreign withholding taxes. The amount of unrecognized deferred tax liability was not significant.

10. Net Income (Loss) Per Share

We compute net income (loss) per share of common stock using the two-class method required for participating securities. Immediately prior to the completion of our initial public offering on July 19, 2012, all shares of outstanding redeemable convertible preferred stock were automatically converted to common stock. Prior to their conversion, we considered all series of our redeemable convertible preferred stock to be participating securities as the holders were entitled to participate in common stock dividends with common stock on an as-converted basis. The holders of our redeemable convertible preferred stock were also entitled to non-cumulative dividends prior and in preference to common stock and did not have a contractual obligation to share in the losses of the Company. Additionally, we consider shares issued upon the early exercise of options subject to repurchase and unvested restricted shares to be participating securities because holders of such shares have non-forfeitable dividend rights in the event of our declaration of a dividend for common shares. In accordance with the two-class method, earnings allocated to these participating securities, which include participation rights in undistributed earnings with common stock, are subtracted from net income to determine net income (loss) attributable to common stockholders.

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by basic weighted-average shares outstanding during the period. All participating securities are excluded from basic weighted-average

shares outstanding. In computing diluted net income (loss) attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Diluted net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by diluted weighted-average shares outstanding, including potentially dilutive securities.

The following table presents the computation of basic and diluted net income (loss) per share of common stock (in thousands, except per share data):

	Year Ended July 31,

The following outstanding options, RSUs, ESPP shares, warrants to purchase redeemable convertible preferred stock, and redeemable convertible preferred stock were excluded from the computation of diluted net income (loss) per common share applicable to common stockholders for the periods presented as their effect would have been antidilutive (in thousands):

11. Employee Benefit Plan

We have established a 401(k) tax - deferred savings plan (401(k) Plan) which permits participants to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code. We are responsible for administrative costs of the 401(k) Plan and have made no contributions to the 401(k) Plan since inception.

12. Segment Information

We conduct business globally and are primarily managed on a geographic theater basis. Our chief operating decision maker reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results, and plans for levels, components, or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure.

Revenue by geographic theater based on the billing address of the partner is as follows (in thousands):

Substantially all of our assets were attributable to the Americas operations as of July 31, 2013 and 2012.

13. Related Party Transactions

Certain members of our board of directors serve as board members or executive officers of certain of our customers and in some cases are also investors of these customers. We believe these transactions with related party customers are carried out on terms that are consistent with similar transactions with our comparable customers. During the year ended July 31, 2013, we recognized revenue of approximately $2,623,000 from sales transactions with significant related party customers. Amounts payable to and due from related party customers were not material at July 31, 2013. We did not have any material sales transactions with related party customers in the year ended July 31, 2012 or 2011.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on our evaluation, our chief executive officer and chief financial officer concluded that, as of July 31, 2013, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.
