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 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 were founded in 2005 to address the limitations that exist in legacy approaches to network security and to restore the firewall as the most strategic point of network control. From 2005 to 2007, our activities were focused on research and development, which resulted in the commercial release of our first product, the PA-4000 Series, as well as our first subscription service, Threat Prevention, in 2007. Since then, we have continued to innovate and consistently introduce new products and services, including the PA-5000 Series and GlobalProtect subscription service in March 2011, the PA-200 and free WildFire modern malware detection subscription service in November 2011, and most recently, the VM-Series, PA-3000 Series, M-100 management appliance, and paid WildFire modern malware prevention subscription service in November 2012.

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. All of our products incorporate our proprietary PAN-OS operating system, which provides a consistent set of capabilities across our entire product line. Our products are designed for different performance requirements throughout an organization, from branch offices to large data centers. Our platform can be centrally managed across an organization with our Panorama product. Services revenue includes sales from 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.

We had more than 11,000 end-customers in over 100 countries as of January 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 the second quarter of fiscal 2013, 63% of our revenue was generated from the Americas, 25% from

Europe, the Middle East, and Africa (EMEA), and 12% from Asia Pacific and Japan (APAC). As of January 31, 2013, we had more than 940 employees.

We have experienced rapid growth and increased demand for our products in recent periods. For the second quarter of fiscal 2013 and 2012, revenues were $96.5 million and $56.7 million, respectively, representing year-over-year growth of 70%.

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.

On July 25, 2012, we closed our initial public offering (IPO), in which 7,130,000 shares of our 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. The total gross proceeds from the offering were $299.5 million. 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.

On October 23, 2012, we closed our secondary offering, in which certain stockholders of our company sold 4,800,000 shares of our common stock at a price to the public of $63.00 per share. The aggregate offering price for shares sold in the offering was approximately $290.3 million, 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.

•        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 subscription 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. 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. 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 and Virtual Systems
         Upgrades. 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.



•        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 three 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. Personnel costs associated with our operations and global
customer support organizations consist of salaries, bonuses, and share-based
compensation. Allocated costs consist of certain facilities, depreciation,
benefits, recruiting, and information technology costs allocated 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, 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 January 31, 2013, we expect to recognize approximately $126.0 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 local 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
         expect general and administrative expense to increase in absolute
         dollars due to additional legal fees and costs associated with pending
         litigation, accounting, 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.

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 Income (Expense), Net

Other income (expense), net consists primarily of the change in fair value of our preferred stock warrant liability. Convertible preferred stock warrants were classified as a liability on our condensed 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, we will no longer incur any charges related to these warrants. We expect other expense to remain at a consistent level in the near term.

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 begun to reorganize our corporate structure and intercompany relationships to more closely align with the international nature of our business activities. This proposed corporate structure may allow us to reduce our overall effective tax rate over the long term through changes in international procurement and sales operations.

Results of Operations

The following tables summarize our results of operations for the periods
presented and as a percentage of our total revenue for those periods. The
period-to-period comparison of results is not necessarily indicative of results
for future periods.
