We develop, manufacture and sell products and services to help companies efficiently and securely manage their Internet traffic, as well as the access and use of their intranet-based software applications. Our application traffic management products, including the BIG-IP Controller, 3-DNS Controller and BIG-IP Link Controller, help manage Internet traffic to servers and network devices in a way that maximizes the availability, scalability and throughput of those network components and the applications that run on them. Our recently acquired FirePass family of network server appliances provides secure user access to corporate networks and individual applications through any standard Web browser. Our unique iControl architecture enables our products to communicate with one another in the network and ensure optimal throughput of traffic, and also allows them to be integrated with third party products, including enterprise applications. This facilitates the automation of repetitive processes and allows the customer to optimize applications on their networks, thereby saving them time and money. As components of an integrated solution, our products address many elements required for successful Internet and intranet business applications, including high availability, high performance, intelligent load balancing, streamlined manageability, remote access to corporate networks, and network and application security. Our solution for application traffic management and security is software-based, which differentiates us from our competitors whose solutions are largely hardware-based. We believe this differentiation enables us to offer our customers greater flexibility, cost-effectiveness and adaptability in response to today’s rapidly changing environment.

Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in financial services, manufacturing, transportation and mobile telecommunications make up the largest percentage of our customer base. We market and sell our products primarily through indirect sales channels in North America, Europe and the Asia Pacific region, and to some direct customer accounts in North America. We have subsidiaries or branch offices in Australia, Canada, China, France, Germany, Hong Kong, Japan, The Netherlands, Singapore, South Korea, Spain, Taiwan, Thailand and the United Kingdom.

In July 2003, we acquired substantially all of the assets and assumed certain liabilities of uRoam, Inc., or uRoam, for $25.0 million in cash. We also incurred $2.4 million of direct transaction costs for a net purchase price of $27.4 million. We hired substantially all of uRoam’s 20 employees, consisting of product development, sales and service personnel. uRoam’s family of FirePass servers is a comprehensive remote access product set that enables users to access applications in a secure fashion, using technology based on the Secure Sockets Layer, or SSL, standard. We believe FirePass provides a security solution that is easier to manage and use, and is more secure, than existing Virtual Private Network, or VPN, solutions, allowing customers to realize significant cost savings for secure remote access to any application. The acquisition of substantially all of the assets of uRoam will allow us to quickly enter the SSL VPN market, broaden our customer base and augment our existing product line.

We were incorporated on February 26, 1996 in the State of Washington. Our headquarters is in Seattle, Washington and our mailing address is 401 Elliott Avenue West, Seattle, Washington 98119. The telephone number at our executive offices is (206) 272-5555.

As a result of the Internet’s capabilities, it has become a fundamental tool for commerce and communications. Since the late 1990’s, businesses have responded to the power, flexibility and economy of the Internet by deploying new Internet Protocol, or IP, based applications, upgrading their client-server applications to new IP-enabled versions, and enabling existing applications for use over the Internet. IP is a communications language that is used for transmitting data over the Internet. During the next several years, we believe this process of deploying IP-enabled applications will accelerate as Web services enable businesses to build applications quickly and easily by integrating software modules available from many different sources. Web services allow businesses to combine functions of existing applications and processes to create new applications and functionality operating over the Internet and beyond the corporate firewall. The purpose of Web services is to enable applications to interact with each other more smoothly, reducing inefficiencies associated with human intervention. A fully-integrated, Web services-enabled computing network would allow personal computers, servers, handheld devices, programs, applications and network equipment to work together directly to generate more efficient data flow and application development and use. In addition, we believe that the growth of Internet usage will continue to be driven by new applications such as Voice over IP, or VoIP, increased penetration of broadband Internet access enabling the remote use of more applications, and the increasing popularity of mobile Internet access through wireless devices such as cellular telephones, personal digital assistants and notebook computers.

Current traffic management products are designed primarily to manage Web traffic. However, few products are equipped with the functionality and flexibility to securely manage the full range of IP-enabled applications, such as Oracle Financials, BEA Weblogic and Siebel Sales Force Automation.

The Open Systems Interconnect Reference Model, or OSI Model, is the framework that describes and defines how networked systems communicate with one another. The OSI Model divides network functions into seven layers and specifies how the layers should interact to enable interoperability between the various users. These interoperability standards have been designed to allow all parts of the network to work together, regardless of the different hardware and software components. IP requires all data transmitted across the Internet to be divided into packets prior to its transmission, and reassembled at its destination. Prior to transmission, each packet of data is automatically given a header that identifies the source and destination of the packet. This header information is used in the OSI Model for the purposes of identifying, routing and sequencing data packets, and is stripped from the data upon arrival at its destination.

Layers 2 and 3 of the OSI Model primarily perform standardized, repetitive tasks such as ensuring that packets of information sent over the Internet arrive at the destination to which they are addressed, and reassembling them in the correct sequence. Unlike Layers 2 and 3, Layers 4-7 are complex and variable and must support end-user applications and processes on a wide variety of platforms and devices. For example, Layer 7 (which encompasses the functions of Layers 5 and 6) enables email, directory look-up and the transfer of files between otherwise incompatible systems.

While traditional Layer 2/3 switching devices are used primarily to ensure correct delivery of packets of information, there is an increasing need for Layer 7 technology that can read the entire contents of a packetized transmission and make intelligent decisions based on a dynamic set of business rules about how to

handle the transmission and where to route it to ensure the availability and optimal performance of applications, servers and the network. Additionally, Layer 2/3, as well as Layer 4, switching devices are primarily hardware-based and are optimized for speed at the expense of flexibility. While most manufacturers of Layer 7 switching devices have also opted for the traditional, costly, hardware-based solutions, this limits the ability of their products to adapt to the rapidly changing requirements of Layer 7 traffic management needed for common end-user applications today.

According to the “Ethernet Switch Report — 5-Year Forecast” prepared by Dell’Oro Group, the traditional Layer 4-7 traffic management market is expected to grow from $432 million in 2002 to $870 million in 2007, representing a five-year compounded annual growth rate of approximately 15%. Additional emerging growth markets for Layer 4-7 traffic management include blade servers, mobile IP and Web services. A blade server is a thin, modular electronic circuit board intended for a single, dedicated application (such as serving Web pages or server load balancing) that can be easily inserted into a space-saving chassis with many similar blade servers. Blade servers, loaded into chassis, are designed to consume less energy and require considerably less space than conventional servers.

As Internet traffic and the use of IP-enabled applications have increased, the demands placed on Layer 7 have also increased and so has the demand for integrated, effective Layer 7 traffic management solutions. Corporations are becoming more reliant on highly sophisticated IP-enabled applications both for their internal operations and for interactions with external customers and partners. The need to guarantee the security of electronic information and transactions has led to the emergence of SSL encryption as the standard for secure IP-enabled traffic. During the interaction between a user and a financial application, for example, data sent from the user to the server is typically encrypted by the user’s Web browser and decrypted by the server, and this process is reversed for data sent back to the user. The use of SSL has continued to grow with the proliferation of Web-based applications that require secure transactions. Increases in the number and sophistication of Web attacks, and the damage caused by such attacks, are also driving demand for more effective security solutions.

SSL is also the core of new technology that addresses the growing need for corporations to provide secure connectivity for the rapidly increasing number of users who access corporate networks and applications from remote locations using a variety of devices ranging from home personal computers and laptops to cellular telephones and personal digital assistants. Many companies currently provide remote access to offsite users through VPNs based on the Internet Protocol Security, or IPSec, framework, which allows remote users to access corporate networks and applications by means of encrypted “tunnels” through the Internet. VPNs are cost-effective because they use the Internet for low-cost transmission of information while providing remote users with a highly secure connection. However, a key security risk associated with IPSec VPNs is that once remote users are connected, they have unrestricted access to all applications and resources within the network.

During the past year, new VPN technology using the SSL protocol has steadily gained acceptance as a more cost-effective solution that is both simpler to deploy and easier to manage than IPSec VPNs. Unlike IPSec VPNs, SSL VPNs do not require customers to purchase and install client-side software on every remote device that accesses the network. Instead, they use the SSL capabilities resident in a remote client’s Internet browser to establish and maintain a secure connection between the client and the VPN server. This eliminates both the initial cost of distributing and implementing client-side software and the recurring costs of upgrading and maintaining it. In addition to providing secure network access, SSL technology can also be used to selectively limit access to certain applications and resources within the network, depending on the identity of the user. Because of the improved security and reduced overall costs, we believe SSL-based solutions will become the dominant method for remote access within the next few years.

According to Infonetics Research’s “VPN and Firewall Products Quarterly Worldwide Market Share and Forecasts for 2Q03” report, the SSL VPN market is expected to grow from $34 million in 2002 to $607 million by 2006, representing a four-year compounded annual growth rate of approximately 105%.

We believe our products are superior to those of our competitors in addressing the growing need among enterprises for integrated, secure, application traffic management.

Software Based Products. From our inception, we have been committed to the belief that the complexity of Layer 7 traffic management requires a software-based rather than a hardware-based solution. We believe our software-based solution for application traffic management and security using commodity hardware provides greatly increased functionality. We also believe our products are more cost-effective, flexible and easily adaptable to today’s constantly changing and increasingly demanding environments than our competitors’ solutions, which are primarily hardware-based. In addition, our software can be easily ported to commodity hardware platforms manufactured by third-party vendors, which has enabled us to license the software to our original equipment manufacturer, or OEM, partners who resell it installed on their own products. It has also created an opportunity for us to sell versions of our software that run on blade servers manufactured by third-party vendors, thereby increasing the target market for our software.

Application Awareness. One of the most important features of our software-based products is their “application awareness.” Our products are designed using a common architecture, called iControl, with a common interface that allows them to communicate with one another and with third-party software and devices. Through our unique, open, iControl application programming interface, or API, third-party applications and network devices can take an active role in shaping IP network traffic, directing traffic based on exact business requirements specified by our customers. For example, our iControl API allows an organization running Oracle software, which has help desks located in Bombay, San Francisco and London, to cause that software to make a real-time request that all email requests for help be directed to a single one of our 3-DNS devices that has been instructed to redirect the requests to different help desks at different times of the day. Similarly, our BIG-IP device managing traffic to an e-commerce Web site could, for example, be directed to recognize transmissions from preferred customers and route them to a server that will expedite their transactions. This “application awareness” capability is one of the most important features of our software-based products and serves as a further point of differentiation for our solution in comparison with those offered by our competitors.

Another key benefit of our software-based solution is that it allows the customer to incorporate specific business rules and processes into the software. This capability, which we call iRules, is a simple tool that can be used to define how the user wants to direct, persist on, or filter traffic based on the needs of each application.

Furthermore, our Universal Inspection Engine, the core of our application traffic management technology, is unique in its ability to inspect IP traffic down to the packet payload level and can direct traffic according to flexible iRules specified by the user. This “deep packet inspection” technology enables powerful offloading, inspection and processing of application-level transactions.

Integrated Traffic Management and Security Solution. Our application traffic management technology is differentiated from other solutions primarily by its ability to intercept, inspect and act on the contents of traffic from virtually every type of IP-enabled application. This deep packet inspection technology allows us to offer an integrated traffic management and security solution that can detect and prevent many network level attacks.

Our FirePass technology enables us to offer secure, remote access through SSL VPNs. FirePass has components that allow remote users to access any application or resource connected to the network, including legacy hosts, desktops and client-server applications. Over the course of the next twelve months we intend to combine our SSL VPN technology with our secure traffic management capabilities, providing significant differentiation from our competitors. This capability will enable our products to provide comprehensive application security at multi-gigabit speeds.

Combined with the sophisticated inspection and control capabilities of our application traffic management technology, we believe that FirePass technology is an ideal platform for the development of advanced application security gateways that can control access to individual applications and the data and resources they

use. Because our BIG-IP software can examine the entire contents of a transmission, it can detect irregularities that might represent a security violation but which may pass undetected through an organization’s firewall and other network security devices. As a result, we believe that FirePass is an ideal platform for the development of technology to protect the integrity of IP-based applications and the data and resources they use. In the future, we plan to use BIG-IP and FirePass to develop a comprehensive security solution that protects network applications from unauthorized access which existing safeguards may fail to prevent.

Our objective is to be the leading provider of secure application traffic management solutions designed to enhance and optimize server availability, security and performance. Key components of our strategy include:

Offering a complete application security solution and product set. We plan to utilize our core technologies from our BIG-IP and FirePass products to deliver standalone and integrated systems that protect applications from hostile and inadvertent threats, including user-to-system application security and system-to-system application security problems. We believe these solutions will differentiate our products in the security market and provide a unique solution to the problem of vulnerability of mission-critical applications.

Increasing the addressable market for our products. In order to enable significant growth over the next three years, we intend to target logical extensions of our traditional traffic management market, including the areas of blade server software; mobile IP infrastructure, which is a mechanism for maintaining transparent network connectivity to mobile hosts; Web services infrastructure; and utility computing and data center virtualization infrastructure, in which corporations pay only for the computing resources they use. This allows their information technology resources to be allocated on an as-needed basis to meet rapidly changing business demands. In addition, we plan to enter adjacent markets, such as the application security market, with our first product offering being an SSL VPN solution.

Investing in technology to continue to meet customer needs. We plan to continue to invest in research and development to provide our customers with complete secure application traffic management and secure remote access solutions. Our software-based platforms are designed to quickly and easily expand the features and functionalities of our products, as well as enabling us to develop additional products that address the complex and changing needs of our customers. We will continue to use commodity hardware in order to ensure performance and cost competitiveness. We also plan to deliver specialized software modules that will allow our customers to purchase software for our platforms as upgrades with specific features based on specific requirements.

Enhancing the existing channel model. We are investing significant resources in order to further develop our indirect sales channels. We plan to expand our indirect sales channels through leading industry resellers, OEMs, systems integrators, Internet service providers and other channel partners. Also, we are leveraging our existing channels by delivering application security products, including FirePass SSL VPNs, making these channels more productive.

Continuing to build and expand relationships with strategic iControl partners. We plan to capitalize on our strategic relationships with enterprise software vendors who have created interfaces to our products through our iControl API. These vendors provide us significant leverage in the selling process, because they recommend our products to their customers. In order to differentiate ourselves further from our competitors we plan to explore opportunities to further embed iControl into existing and new third party products and to jointly market and sell our solutions to enterprise customers with these key partners.

Enhancing our brand. We plan to continue building brand awareness that positions us as one of the leading providers of secure application traffic management solutions. Our goal is for the F5 brand to be synonymous with superior performance, high-quality customer service and ease of use.

Our core technology is software for IP application traffic management and secure remote access to IP networks and applications. We also manufacture several types of systems (which are software and hardware

bundled together as an integrated product offering): BIG-IP server appliances; BIG-IP application switches; 3-DNS Controller; BIG-IP Link Controller; and FirePass SSL VPN servers, each incorporating our software with commodity components to provide a complete solution.

Our flagship product is the BIG-IP Controller for local-area application traffic management. BIG-IP software runs on a variety of commodity hardware platforms, including IP application switches and server appliances manufactured by us and our OEM partners, as well as on blade servers manufactured by server vendors such as Dell Inc., Fujitsu Siemens Computers GmbH, Hewlett Packard Company, International Business Machines Corporation and NEC Corporation. The core of BIG-IP is sophisticated software that manages IP traffic at Layer 7, also known as the application layer. Our BIG-IP application switches also perform Layer 2/3 switching and, we believe, industry-leading Layer 4 switching. But we believe it is the superior performance and functionality of the BIG-IP Layer 7 traffic management software that distinguishes it from competing products sold by Cisco Systems, Nortel Networks and others. In addition, BIG-IP has a patented feature, known as “cookie persistence,” which establishes a link between a user and a specific server and enables the user to return to that server if the connection is broken before a transaction is completed.

BIG-IP server appliances were our original products and accounted for 16.9% of our product revenue for fiscal year 2003. The BIG-IP 520 and 540 server appliances are equipped with Intel processors for high-speed Layer 4-7 processing and are designed to accommodate easily-installed upgrade cards that provide fast, integrated SSL encryption and decryption. Integrated SSL processing has been an important factor of system sales. By offloading SSL processing, which requires significant server and computing power, from servers to our traffic management systems, customers can free up valuable server space for other applications.

In September 2001 we introduced our first IP application switch, the BIG-IP 5000, in response to customer demand for systems with an increased number of ports allowing them to be connected to many different types of network devices, integrated Layer 2/3 switching and SSL processing capability. We currently offer the high-end BIG-IP 5100, the BIG-IP 2400 mid-range product with integrated Layer 4 switching on an application-specific integrated circuit, or ASIC, developed by our hardware team, and the BIG-IP 1000 entry-level switch.

Our other traffic management products include 3-DNS Controller and BIG-IP Link Controller. 3-DNS allows enterprises with geographically dispersed data centers to direct traffic to a particular data center in accordance with customized business rules or to redirect traffic to an available data center if one of their sites becomes overloaded or is shut down for any reason. Link Controller allows enterprises with more than one Internet service provider to manage the use of their available bandwidth to minimize costs while ensuring the highest quality of service. 3-DNS and Link Controller are sold separately on individual IP application switches and server appliances, or bundled with BIG-IP on a single appliance or IP application switch.

FirePass systems provide SSL VPN access for remote users of IP networks and any applications connected to those networks from any standard Web browser on any device. The components of FirePass include a dynamic policy engine, which manages user authentication and authorization privileges, and special components that enable corporations to give remote users controlled access to the full array of applications and resources within the network.

Our FirePass line of SSL VPN servers currently includes the FirePass 1000 and the FirePass 4000, which support 100 and 1000 concurrent users, respectively. Both support the complete range of FirePass software features and offer a comprehensive solution for Web-based remote access to corporate applications and desktops.

Our products also come equipped with our iControl and iControl Services Manager, or iSM, functions, which are designed to facilitate the broader use of our products. In early 2001, we recognized a growing need for traffic management products that could not only communicate with one another, but also with the increasing number and variety of IP-enabled enterprise applications being deployed by large organizations. At that time we published the iControl interface in a free software development kit, or SDK, that allows customers and independent software vendors to modify their programs to communicate with our products. The use of iControl reduces or eliminates the need for human involvement, significantly reducing the cost of performing basic network functions and dramatically reducing the likelihood of error. Adding this extra functionality to their products is attractive to independent software vendors, and since the introduction of our iControl SDK, we have formed relationships with dozens of software developers including Microsoft Corporation, Oracle Corporation, BEA Systems, Inc., International Business Machines Corporation, Hewlett Packard Company, Siebel Systems, Inc., and Mercury Interactive Corporation. Although we do not derive revenue from iControl itself, the sale of iControl-enabled independent software vendor products helps promote and often leads directly to the sale of our other products.

iControl Services Manager takes advantage of iControl to provide a single, centralized management and operational interface for our devices. This feature allows customers with dozens or hundreds of our products to upgrade or modify the software on those products simultaneously from a single console. This lowers the cost and simplifies the task of deploying, managing and maintaining our products and reduces the likelihood of error when blanket changes are implemented.

Our future success depends on our ability to maintain technology leadership in secure application traffic management by constantly improving our products and by developing new products to meet the changing needs of our customers. Our product development group, which is divided along product lines, employs a standard process for the development, documentation and quality control of software and systems that is designed to meet these goals. We are currently focused on developing enhancements to our existing traffic management and SSL VPN products in order to deliver greater functionality and performance. We are also developing an integrated application security gateway, which will combine our security and traffic management technologies in order to deliver a network device that protects applications from hostile attacks. By ensuring user-to-system application security and system-to-system application security, the application security gateway will provide comprehensive application security.

In order to advance our product development, we also engage in technology partnerships with software and component manufacturers that allow us to integrate industry-standard technology with our own products. During the past two years, we have had a close working relationship with Broadcom Corporation, which manufactures the Layer 2/3 switch chips and SSL processors used in our family of application switches.

Our principal software engineering group, which develops our application traffic management technology, is located in our headquarters in Seattle, Washington. Our FirePass product development team, which includes the original developers of the technology, is located in San Jose, California. Our hardware engineering group is located in Spokane, Washington. Members of these teams collaborate closely with one another on specific projects.

During the fiscal years ended September 30, 2003, 2002 and 2001, we had research and product development expenses of $19.2 million, $18.0 million and $17.4 million, respectively.

We have a globally diversified base of customers, consisting primarily of large enterprises. Although we do not target specific vertical markets, enterprise customers in financial services, manufacturing, transportation and mobile telecommunications currently make up the largest percentage of our customer base. The other significant components of our customer base are Internet service providers, Internet hosting companies and

Internet commerce companies. In fiscal year 2003, international sales represented 34.9% of our net revenues. See note 14 to our consolidated financial statements included elsewhere in this annual report on Form 10-K for additional information regarding our revenues by geographic area.

Prior to fiscal year 2001, our end-user customer base was comprised primarily of Internet service providers, Internet hosting companies and Internet startups engaged in e-commerce. Starting in the first half of fiscal year 2001, as demand from those customers weakened, we successfully refocused our marketing and sales efforts on large enterprises, which currently account for the majority of our revenue, without any material adverse effect on our revenues. Consistent with our goal of building a strong channel sales model, the majority of our revenue is generated by sales though our distributors, value-added resellers and systems integrators.

For fiscal year 2003, sales to Ingram Micro Inc., one of our distributors, represented 12.6% of our revenues. Our agreement with Ingram Micro is a standard, non-exclusive distribution agreement that renews automatically on an annual basis and is terminable by either party with 30 days’ prior written notice. The agreement grants Ingram Micro the right to distribute our products to resellers in North America and certain other territories internationally, with no minimum purchase requirements.

We sell our software, systems and services to large enterprise customers through a variety of channels, including OEMs, distributors, value-added resellers and systems integrators. A substantial amount of our revenue for fiscal year 2003 was derived from these channel sales. We also sell our products and services to major accounts through our own direct sales force. In most cases, service contracts are negotiated directly with the customer. Typically, our agreements with our channel partners are not exclusive and do not prevent them from selling competitive products. These agreements typically have terms of one year with no obligation to renew, and typically do not provide for exclusive sales territories or minimum purchase requirements.

Direct sales. Our field sales personnel are located in major cities throughout North America, Europe and the Asia Pacific region. The inside sales team generates and qualifies leads for regional sales managers and helps manage accounts by serving as a liaison between the field and internal corporate resources. We sell our products directly to a limited group of customers, primarily OEMs, including Dell Inc., Fujitsu Siemens Computers GmbH, Hewlett Packard Company, International Business Machines Corporation and NEC Corporation, and certain large enterprise end-users whose accounts are managed by our major account services team. Field systems engineers also support our regional sales managers by participating in joint sales calls and providing pre-sale technical resources as needed. The majority of our field sales personnel work closely with our channel partners to assist them in selling our products to their customers, as the bulk of our sales are made through distributors or value-added resellers.

Distributor and value-added reseller relationships. We have established relationships with large national and international distributors, local and specialized distributors and value-added resellers. The distributors sell our products, and the value-added resellers not only sell our products, but also assist their customers in network design, installation and testing. Our primary distributor relationships include Ingram Micro Inc. in North America and in certain territories internationally, and our primary value-added reseller relationships include Milestone Systems, Inc.

Systems integrators. We also market our products through strategic relationships we have with systems integrators, which design and install networks that incorporate our systems. Systems integrators typically do not purchase and resell equipment to their customers. Instead they typically recommend equipment to their customers for use in the systems they design and install. We currently have relationships with a number of systems integrators, including Electronic Data Systems Corporation.

The cornerstone of our marketing strategy is the establishment of strong partnerships with large, prominent companies that are leaders in their respective industries. By partnering with these firms, we have

been able to gain visibility with prospective customers and access to large accounts that we would not have been able to achieve on our own. Currently, we have three principal types of marketing partnerships that overlap to varying degrees with our sales channel partnerships. These include:

iControl partnerships. We have established relationships with various independent software vendors who have adapted their applications to interact with our products via the iControl interface. iControl enhances the functionality of third party applications by enabling them to control the network in an automated way, based on business policies and rules associated with the application. As a result, customers who purchase iControl-enabled applications have an incentive to purchase our products in order to take advantage of the enhanced functionality made possible through our technical cooperation.

Blade server relationships. We have relationships with various system vendors (Dell Inc., Fujitsu Siemens Computers GmbH, Hewlett Packard Company, International Business Machines Corporation and NEC Corporation) to market our BIG-IP Blade Controller software for use on their blade server systems. Market focus and strategy are different for each relationship. In some of these relationships, vendors or their channel partners resell Blade Controller software to their customers.

OEM partnership with Dell Inc. We license our software to Dell, which resells it on its own line of traffic management products. In conjunction with this arrangement, we participate in joint marketing programs with Dell.

We engage in a number of marketing programs and initiatives aimed at promoting our brand and creating market awareness of our technology and products. These include actively participating in industry trade shows and briefing industry analysts and members of the trade press on our latest products, and on new business and technology partnerships. In addition, we market our products to chief information officers and other information technology professionals through targeted advertising, direct mail and high-profile Web events.

Our backlog represents orders confirmed with a purchase order for products to be shipped generally within 90 days to customers with approved credit status. Orders are subject to cancellation, rescheduling by customers or product specification changes by the customers. Although we believe that the backlog orders are firm, purchase orders may be cancelled by the customer prior to shipment without significant penalty. For this reason, we believe that our backlog at any given date is not a reliable indicator of future revenues.

Our ability to provide consistent, high-quality customer service and technical support is a key factor in attracting and retaining customers. Prior to the installation of our products, our services personnel work with customers to analyze their network needs and determine the best way to deploy our products and configure product features and functions to meet those needs. Our services personnel also provide on-site installation and training services to help customers make optimal use of product features and functions. Installation generally occurs within 30 days of product shipment to the customer.

At the time of purchase, customers typically purchase a one-year maintenance contract, renewable annually, which entitles them to an array of services provided by our technical support team. Maintenance services provided under the contract include online updates, software error correction releases, Ask F5, described below, and remote support through a 24 hours a day, 7 days a week help desk, although not all service contracts entitle a customer to round-the-clock call center support. Updates to our software are only available to customers with a current maintenance contract. Our technical support team also offers seminars and training classes for customers on the configuration and use of products, including local and wide area network system administration and management. In addition, we have a professional services team able to provide a full range of fee-based consulting services, including comprehensive network management, documentation and performance analysis, and capacity planning to assist in predicting future network requirements.

We also offer, as part of our maintenance service, an online, automated, self-help customer support function called Ask F5 that allows customers to answer many commonly asked questions without having to call our support desk. This allows the customer to rapidly address issues and questions, while significantly reducing the number of calls to our support desk. This enables us to provide comprehensive customer support while keeping our support related expenses at a manageable, consistent level.

We outsource the manufacturing of our pre-configured hardware platforms to a contract manufacturer, Solectron Corporation, which assembles each product to our specifications. Hardware platforms for our traffic management products consist primarily of a commodity computing platform, custom and commodity ASICs, a rack-mount enclosure system and a custom-designed front panel. Solectron also installs our application traffic management software onto these hardware platforms and conducts functionality testing, quality assurance and documentation control prior to shipping our products.

Our agreement with Solectron allows them to procure component inventory on our behalf based upon a rolling production forecast. Subcontractors supply Solectron with standard parts and components for our products based on our production forecast. We are contractually obligated to purchase component inventory that our contract manufacturer procures in accordance with the forecast, unless we give notice of order cancellation in advance of applicable lead times. For any completed product inventory carried by Solectron beyond 30 days, Solectron will charge us a monthly carrying fee of 1.5%. Alternatively, we have the option to purchase inventory held by Solectron beyond 30 days to avoid incurring related carrying charges. As protection against component shortages and to provide replacement parts for our service teams, we also stock limited supplies of certain key components for our products.

In addition, we obtain all of the Layer 2/3 switch chips and the SSL processors used in our family of application switches from Broadcom Corporation. We purchase components from Broadcom on a purchase order basis, with pricing updated at agreed upon intervals. Certain products purchased from Broadcom were designed with our input, but are not exclusive to us. We also designed a Layer 4 ASIC, which is used in one of our products and is manufactured for us by a contract semiconductor foundry.

Our principal competitors in the traffic management market are Cisco Systems, Inc. and Nortel Networks Corporation. Other competitors in this market include Foundry Networks, Inc., NetScaler, Inc. and Radware Ltd.

Cisco Systems has a product set similar to ours and holds the largest share of the market. Cisco has a longer operating history and significantly greater financial, technical, marketing and other resources than we do. Cisco also has a more extensive customer base and broader customer relationships, including relationships with many of our current and potential customers. In addition, Cisco has large, well-established, worldwide customer support and professional services organizations and a more extensive direct sales force and sales channels.

Like Cisco, Nortel has a product set similar to ours and has a longer operating history, greater resources, a larger customer base and a larger sales and service organization. Whereas Cisco has historically focused on large corporate enterprise customers, Nortel has primarily focused on telecommunications and Internet service provider customers.

Because of our relatively smaller size, market presence and resources, Cisco, Nortel and other larger competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements. There is also the possibility that these companies may adopt aggressive pricing policies to gain market share. As a result, our competitors pose a serious competitive threat that could undermine our ability to win new customers and maintain our existing customer base.

Our most prominent competitors in the SSL VPN market are Aventail Corporation, Neoteris, Inc. and SafeWeb, Inc. NetScreen Technologies, Inc. recently announced its acquisition of Neoteris and Symantec

Corp. recently announced its acquisition of SafeWeb, with both moves designed to allow the buyer to enter the SSL VPN market. Nokia Corporation and Nortel Networks Corporation have also recently introduced SSL VPN products. While we believe our FirePass products are superior to their offerings, some of our competitors have resources and distribution channels that are much larger than ours and could give them a significant competitive advantage in the SSL VPN market. We currently compete with Nortel in the Layer 4-7 traffic management market, and Nokia resells our Layer 4-7 products. In the near term, we do not anticipate that our entry into the SSL VPN market will affect Nokia’s resale of our Layer 4-7 products.

SSL VPNs are a potential replacement for IPSec VPNs, the most widely deployed solution for secure remote access today. The current leaders in the IPSec VPN market are Check Point Software Technologies, Ltd. and NetScreen, both of which are larger and better-known vendors than us.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We have obtained three patents in the United States and have applications pending for various aspects of our technology. Our future success depends in part on our ability to protect our proprietary rights to the technologies used in our principal products. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use trade secrets or other information that we regard as proprietary. In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. We cannot assure you that any issued patent will preserve our proprietary position, or that competitors or others will not develop technologies similar to or superior to our technology. Our failure to enforce and protect our intellectual property rights could harm our business, operating results and financial condition.

In addition to our own proprietary software, we incorporate software licensed from several third-party sources into our products. These licenses generally renew automatically on an annual basis. We believe that alternative technologies for this licensed software are available both domestically and internationally.

F5, F5 Networks, Big-IP, 3-DNS, iControl, iRules and FirePass are our trademarks or registered trademarks. Oracle Financials, BEA Weblogic and Siebel Salesforce Automation are trademarks of Oracle Corporation, BEA Systems, Inc. and Siebel Systems, Inc., respectively.

As of September 30, 2003, we employed 507 full-time persons, including 145 in product development, 211 in sales and marketing, 84 in professional services and technical support and 67 in finance, administration and operations. None of our employees is represented by a labor union. We have experienced no work stoppages and believe that our employee relations are good.

Our principal administrative, sales, marketing, research and development facilities are located in Seattle, Washington and consist of approximately 195,000 square feet. In April 2000, we amended and restated the lease agreement on two buildings for our corporate headquarters. The lease commenced in July 2000 on the first building; and the lease on the second building commenced in September 2000. The lease for both buildings expires in 2012 with an option for renewal. The lease for the second building has been fully subleased through 2012. We believe that our existing properties are in good condition and suitable for the conduct of our business. We also lease office space for our product development personnel in Spokane, Washington and San Jose, California and for our sales and support personnel in Washington DC, New York, Hong Kong, Singapore, Taiwan, Japan, Australia, Germany, France, and the United Kingdom. The lease for our Washington, DC office has been primarily subleased through 2007.

In July and August 2001, a series of putative securities class action lawsuits were filed in United States District Court, Southern District of New York against certain investment banking firms that underwrote the Company’s initial and secondary public offerings, the Company and some of the Company’s officers and directors. These cases, which have been consolidated under In re. F5 Networks, Inc. Initial Public Offering Securities Litigation, No. 01 CV 7055, assert that the registration statements for the Company’s June 4, 1999 initial public offering and September 30, 1999 secondary offering failed to disclose certain alleged improper actions by the underwriters for the offerings. The consolidated, amended complaint alleges claims against the Company and those of our officers and directors named in the complaint under Sections 11 and 15 of the Securities Act of 1933, and under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. Other lawsuits have been filed making similar allegations regarding the public offerings of more than 300 other companies. All of these various consolidated cases have been coordinated for pretrial purposes as In re. Initial Public Offering Securities Litigation, Civil Action No. 21-MC-92. In October 2002, the directors and officers were dismissed without prejudice. The issuer defendants filed a coordinated motion to dismiss these lawsuits in July 2002, which the Court granted in part and denied in part in an order dated February 19, 2003. The Court declined to dismiss the Section 11 and Section 10(b) and Rule 10b-5 claims against the Company. In June 2003, a proposal was made for the settlement and release of claims against the issuer defendants, including us, and their directors and officers in exchange for a guaranteed recovery to be paid by the issuer defendants’ insurance carriers and an assignment of certain claims against the underwriters. The settlement is subject to a number of conditions, including approval by the proposed settling parties and the Court. If the settlement does not occur, and litigation against us continues, we believe we have meritorious defenses and intend to defend the case vigorously. Securities class action litigation could result in substantial costs and divert our management’s attention and resources. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of the litigation, and any unfavorable outcome could have a material adverse impact on our business, financial condition and operating results.

We are not aware of any additional pending legal proceedings against us that, individually or in the aggregate, would have a material adverse effect on our business, operating results, or financial condition. We may in the future be party to litigation arising in the course of our business, including claims that we allegedly infringe third-party trademarks and other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

During the fourth quarter of the fiscal year ended September 30, 2003, no matters were submitted to a vote of the shareholders of the Company, either through the solicitation of proxies, or otherwise.

Our common stock is traded on the Nasdaq National Market under the symbol “FFIV.” The following table sets forth the high and low sales prices of our common stock as reported on the Nasdaq National Market.

The last reported sales price of our common stock on the Nasdaq National Market on October 29, 2003 was $24.28.

As of October 28, 2003, there were 130 holders of record of our common stock. As many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial holders of our common stock represented by these record holders.

Our policy has been to retain cash to fund future growth. Accordingly, we have not paid dividends and do not anticipate declaring dividends on our common stock in the foreseeable future.

The following discussion and analysis should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K.

Net Revenues. Total net revenues increased 7.0% in fiscal year 2003 from fiscal year ended September 30, 2002, or fiscal year 2002, compared to an increase of 0.8% in fiscal year 2002 from fiscal year 2001. International revenues represented 34.9%, 32.2% and 33.3% of net revenues in fiscal years 2003, 2002 and 2001, respectively. We expect international sales will continue to represent a significant portion of net revenues, although we cannot provide assurance that international revenues as a percentage of net revenues will remain at current levels.

Net product revenues were $84.2 million for fiscal year 2003 compared to $82.6 million for fiscal year 2002 and $78.6 million for fiscal year 2001. The 2.0% increase in fiscal year 2003 was primarily the result of sales in Asia Pacific and Europe. The 5.0% increase in fiscal year 2002 was primarily the result of strong sales in North America, partially offset by decreased sales in the Asia Pacific region.

Sales of our BIG-IP products represented 82.8%, 84.1% and 78.9% of total product revenues in fiscal years 2003, 2002 and 2001, respectively. Our BIG-IP products consist of server appliances and IP application switches. Our IP application switch products, including BIG-IP 1000, BIG-IP 2400 and the BIG-IP 5100 were introduced in the first quarter of fiscal year 2003 and represented 41.8% of product revenues in fiscal year 2003. We expect to continue to derive a significant portion of our product revenues from sales of BIG-IP in

Net service revenues were $31.7 million for fiscal year 2003 compared to $25.7 million for fiscal year 2002 and $28.7 million for fiscal year 2001. Service revenues increased by 23.3% in fiscal year 2003 primarily due to an increase in the renewal of service and support contracts by existing customers, as our installed base increased. The 10.6% decrease in service revenues in fiscal year 2002 compared to fiscal year 2001 was primarily due to changes in pricing and a larger percentage of our resellers providing maintenance and installation to end-users, partially offset by an increase in the renewal of service and support contracts by existing customers.

Ingram Micro Inc., one of our domestic distributors, accounted for 12.6% of our total net revenues for fiscal year 2003. Ingram Micro accounted for 17.8% of our accounts receivable as of September 30, 2003. No individual customer or distributor represented more than 10% of our total net revenues or accounts receivable for fiscal years 2002 and 2001.

Cost of Net Product Revenues. Cost of net product revenues decreased to $17.8 million in fiscal year 2003 from $20.2 million in fiscal year 2002 and $33.2 million in fiscal year 2001. Cost of net product revenues decreased as a percent of net product revenue to 21.2% in fiscal year 2003 from 24.5% in fiscal year 2002 and 42.3% in fiscal year 2001. The decrease in fiscal year 2003 was primarily the result of lower warranty, manufacturing and component costs. The decrease in fiscal year 2002 was primarily the result of lower excess inventory charges and manufacturing costs partially offset by increased warranty costs. Further, in fiscal year 2002, we unified our supply chain with a single contract manufacturer and, as result, have improved our manufacturing efficiencies, as well as realized lower component costs.

Cost of Net Service Revenues. Cost of net service revenues decreased to $9.1 million in fiscal year 2003 from $10.2 million in fiscal year 2002 and $12.3 million in fiscal year 2001. Cost of net service revenues decreased as a percent of net service revenues to 28.6% in fiscal year 2003 from 39.8% in fiscal year 2002 and 42.7% in fiscal year 2001. The decrease in fiscal year 2003 was primarily due to a decrease in personnel related costs associated with a decline in service personnel headcount and related costs during the last quarter of fiscal year 2002. This decrease in fiscal year 2002 was primarily due to improved operational efficiencies and a decrease in headcount and related costs.

Sales and Marketing. Sales and marketing expenses consist primarily of the salaries, commissions and related benefits of our sales and marketing staff, the costs of our marketing programs, including public relations, advertising and trade shows, and an allocation of our facilities and depreciation expenses. Sales and marketing expenses increased 5.7% to $53.5 million in fiscal year 2003 from $50.6 million in fiscal year 2002. The increase in fiscal year 2003 related primarily to increased payroll and related personnel costs, and travel related expenses. Sales and marketing expenses decreased to $50.6 million in fiscal year 2002 from $50.8 million in fiscal year 2001. The decrease in fiscal year 2002, compared to fiscal year 2001, was due to a decrease in trade show and promotional activities and decreased business travel expenses, partially offset by increased personnel costs as we continued to expand our international operations. We expect to continue to increase sales and marketing expenses in order to grow net revenues and expand our brand awareness.

Research and Development. Research and development expenses consist primarily of the salaries and related benefits for our product development personnel and an allocation of our facilities and depreciation expenses. Research and development expenses increased 7.0% to $19.2 million in fiscal year 2003, from $18.0 million in fiscal year 2002 and $17.4 million in fiscal year 2001. The increase in fiscal year 2003 was due to increased personnel related costs associated with an increase in headcount to 145 from 127 primarily as a result of the acquisition of substantially all the assets of uRoam and an increase in prototype expenses. The increase in fiscal year 2002 was due to increased personnel related costs and expenses related to the development of new products. We expect to continue to increase research and development expenses as our future success is dependent on the continued enhancement of our current products and our ability to develop new products that meet the changing needs of our customers.

General and Administrative. General and administrative expenses consist primarily of the salaries, benefits and related costs of our executive, finance, information technology, human resource and legal personnel, third-party professional service fees, bad debt charges and an allocation of our facilities and depreciation expenses. General and administrative expenses decreased 20.1% to $12.0 million in fiscal year 2003 from $15.0 million in fiscal year 2002 and $18.8 million in fiscal year 2001. The decrease in fiscal year 2003 is primarily due to a decrease in professional services related to patent prosecution and other activities related to our intellectual property and lower bad debt charges. The decrease in fiscal year 2002 is primarily due to lower bad debt charges and lower facilities expenses resulting from the sublease of one of our buildings, partially offset by an increase in professional services related to patent prosecution and other activities related to our intellectual property.

Restructuring Charges. During the third quarter of fiscal year 2002, we recorded a restructuring charge of $2.8 million in connection with management’s decision to exit the cache appliance business. As a result of changes in the business, we wrote down certain assets, consolidated operations and terminated 47 employees throughout all divisions of F5 Networks. In July 2002, all identified employees had been notified and terminated resulting in an additional charge of $0.5 million related to employee separation costs.

During the first fiscal quarter of 2001, we recorded a restructuring charge totaling $1.1 million in connection with our management’s decision to bring operating expenses in line with the business revenue growth model. Accordingly, we terminated 96 employees throughout all divisions of F5 Networks. By the end of January 2001, all identified employees had been terminated. During the quarter ended March 31, 2001, we reversed $96,000 of previous estimates. As of September 30, 2001, substantially all of the restructuring charges accrued during the first quarter of 2001 had been paid. See note 8 to our consolidated financial statements included elsewhere in this annual report on Form 10-K for a discussion of continuing restructuring liabilities.

Amortization of Unearned Compensation. We have recorded a total of $8.3 million of stock compensation costs since our inception through September 30, 2003. These charges represent the difference, on the grant date, between the exercise price and the deemed fair value of certain stock options granted to our employees and outside directors. These options generally vest ratably over a four-year period. We are amortizing these costs using an accelerated method as prescribed by Financial Accounting Standards Board, or FASB, interpretation No. 28 (FIN No. 28) and recorded stock compensation charges of $0.1 million, $0.4 million, and $2.6 million for the fiscal years 2003, 2002 and 2001, respectively. Unamortized stock-based compensation totaled $10,000 at September 30, 2003.

Other Income, Net. Other income, net, consists primarily of investment income and foreign currency transaction gains and losses. Other income, net, decreased 47.1% to $0.8 million in fiscal year 2003 from $1.4 million in fiscal year 2002 and $2.0 million in fiscal year 2001. The decrease in fiscal year 2003 was primarily due to realized losses on sales of investments, declining interest rates and interest income, and an increase in foreign currency transaction losses. The decrease in fiscal year 2002 was related to declining interest rates and investment income.

Provision for Income Taxes. The provision for income taxes was $0.9 million, $0.5 million and $4.1 million for fiscal years 2003, 2002 and 2001, respectively. The provision for income taxes represents foreign taxes related to our international operation, with the exception of fiscal year 2001, which includes a charge of $3.4 million to provide a full valuation allowance against the net deferred tax assets. No federal or state income taxes were provided in fiscal years 2002 or 2003.

We have funded our operations with our cash balances, cash generated from operations and proceeds from public offerings.

We consider all highly liquid investments with maturities of three months or less to be cash equivalents. Cash and cash equivalents totaled $10.4 million at the end of fiscal year 2003, compared to $20.8 million at the end of fiscal year 2002 and $18.3 million at the end of fiscal year 2001.

Cash provided by operating activities during fiscal year 2003 was $14.6 million compared to $9.5 million in fiscal year 2002 and cash used in operating activities was $11.8 million in fiscal year 2001. Cash provided by operating activities in fiscal years 2003 and 2002 resulted primarily from cash generated from net income, after adjusting for non-cash charges, changes in operating assets and liabilities and an increase in deferred revenue due to an increase in the renewal of service and support contracts by existing customers. Cash used in operating activities in fiscal year 2001 resulted primarily from operating losses, partially offset by a decrease in net accounts receivable.

Cash used in investing activities was $38.1 million for the fiscal year 2003, $12.7 million for fiscal year 2002 and $24.7 million for fiscal year 2001. The cash used in investing activities in fiscal year 2003 was primarily the result of the $27.4 million used to acquire substantially all the assets of uRoam and purchase of investments and property and equipment partially offset by the sale of investments. Cash used in each of fiscal years 2002 and 2001 were due primarily to the purchase of investments and property and equipment, partially offset by the sale of investments.

Cash provided by financing activities was $12.8 million for fiscal year 2003 compared to $5.5 million for fiscal year 2002 and $36.3 million for the fiscal year 2001. In fiscal years 2003 and 2002, our financing activities primarily related to cash received from the exercise of employee stock options and the purchase of common shares under our employee stock purchase plan. In fiscal year 2001, we also received $34.9 million related to the issuance of common stock and warrants to Nokia Finance International B.V. The warrants expired in January 2003 without being exercised.

We expect that our existing cash balances and cash from operations will be sufficient to meet our anticipated working capital and capital expenditures for the foreseeable future.

As of September 30, 2003, our principal commitments consisted of obligations outstanding under operating leases. In April 2000, we amended and restated the lease agreement relating to two buildings for our corporate headquarters. The lease commenced in July 2000 on the first building; and the lease on the second building commenced in September 2000. The lease for both buildings expires in 2012 with an option for renewal. The lease for the second building has been fully subleased through 2012. We established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6.0 million certificate of deposit is required through November 2012, unless the lease is terminated before then. This amount has

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our financial statements.

Revenue Recognition. We recognize revenue in accordance with the guidance provided under Statement of Position (SOP) No. 97-2, “Software Revenue Recognition,” and SOP No. 98-9 “Modification of SOP No. 97-2, Software Revenue Recognition, with Respect to Certain Transactions.” Statement of Financial Accounting Standards (SFAS) No. 48, “Revenue Recognition When Right of Return Exists,” and Securities and Exchange Commission, or SEC, Staff Accounting Bulleting (SAB) No. 101, “Revenue Recognition in Financial Statements.”

We sell products through resellers, OEMs, and other channel partners, as well as directly to end users, under similar terms. We recognize product revenue upon shipment, net of estimated returns, provided that collection is determined to be probable and no significant obligations remain. Product revenues from OEM agreements are recognized based on reporting of sales from the OEM partner. Whenever a software license, hardware, installation and post-contract customer support, or PCS, elements are combined into a package with a single “bundled” price, a portion of the sales price is allocated to each element of the bundled elements based on their respective fair values as determined when the individual elements are sold separately. Revenues from the license of software are recognized when the software has been shipped and the customer is obligated to pay for the software. When rights of return are present and we cannot estimate returns, we recognize revenue when such rights of return lapse. Revenues for PCS are recognized on a straight-line basis over the service contract term. PCS includes rights to upgrades, when and if available, a limited period of telephone support, updates, and bug fixes. Installation revenue is recognized when the product has been installed at the customer’s site. Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and revenues are recognized when the consulting has been completed. Training revenue is recognized when the training has been completed.

Our ordinary payment terms to our domestic customers are net 30 days. Our ordinary payment terms to our international customers are net 30 to 90 days based on normal and customary trade practices in the individual markets. We have offered extended payment terms beyond ordinary terms to some customers. For these arrangements, revenue is recognized when payments become due.

Reserve for Doubtful Accounts. Estimates are used in determining our allowance for doubtful accounts and are based on a percentage of our accounts receivable by aging category. In determining these percentages, we evaluate historical write-offs, current trends in the credit quality of our customer base, as well as changes in the credit policies. We perform ongoing credit evaluations of our customers’ financial condition and generally do not require any collateral. If there is a deterioration of a major customer’s credit worthiness or actual defaults are higher than our historical experience, our allowance for doubtful accounts may not be insufficient.

Reserve for Product Returns. Product returns are estimated based on historical experience by type of product and are recorded at the time revenues are recognized. In some instances, product revenue from distributors is subject to agreements allowing rights of return. Accordingly, we reduce recognized revenue for estimated future returns at the time revenue is recorded. When rights of return are present and we cannot estimate returns, revenue is recognized when such rights lapse. The estimates for returns are adjusted periodically based upon changes in historical rates of returns, inventory in the distribution channel, and other related factors. It is possible that these estimates will change in the future or that the actual amounts could vary from our estimates and result in reductions to recognized revenues.

Reserve for Excess or Obsolete Inventory. We currently reserve for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory charges may be required.

Reserve for Warranties. A warranty reserve is established based on our historical experience and an estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. While we believe that our warranty reserve is adequate and that the judgment applied is appropriate, such amounts estimated to be due and payable could differ materially from what will actually transpire in the future.

Income Tax Valuation Allowance. The Company has net deferred tax assets at September 30, 2003 totaling approximately $30.7 million, which are fully offset by a valuation allowance due to management’s determination that the criteria for recognition have not been met. In the event management were to determine that the Company would be able to realize its net deferred tax assets in the future, an adjustment to the deferred tax assets would be made, increasing net income (or decreasing net loss) in the period in which such a determination was made.

As of September 30, 2003, approximately $12.7 million of the valuation allowance related to the Company’s net operating loss carry forwards is derived from the tax benefits of stock option deductions. At such time as the valuation allowance related to their deductions is released, the benefits will be credited to additional paid in capital.

Purchase Price Allocation. During 2003, the Company acquired substantially all of the assets and assumed certain liabilities of uRoam, Inc. for cash of $25 million. The Company also incurred $2.4 million of direct transaction costs for a total purchase price of $27.4 million. The total purchase price was allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair value. The excess of the purchase price over the fair value was recorded as goodwill. The fair value assigned to the tangible and intangible assets acquired and liabilities assumed were based upon estimates and assumptions developed by management and other information compiled by management.

In May 2003, FASB issued Statement of Financial Accounting Standard No. 150 “Accounting for Certain Financial Instruments with Characteristics of Both Liability and Equity” (SFAS No. 150). SFAS No. 150 establishes standards for how companies classify and measure certain financial instruments with characteristics of both liabilities and equity. SFAS No. 150 is effective for financial instruments entered into or modified after May 31, 2003. The adoption of this standard did not have an impact on our consolidated financial statements.

investment meets the characteristic of a derivative as discussed in Statement of Financial Accounting Standards No. 133, when a derivative contains a financing component, amends the definition of an “underlying” to conform it to the language used in FASB interpretation No. 45, “Guarantor Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” and amends certain other existing pronouncements. The adoption of this standard did not have an impact on our consolidated financial statements.

In January 2003, FASB issued Interpretation No. 46 (FIN No. 46), “Consolidation of Variable Interest Entities,” which addresses consolidation by business enterprises of variable interest entities that either: (1) do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) the company will hold a significant variable interest in, or have significant involvement with, an existing variable interest entity. The adoption of this interpretation did not have an impact on our consolidated financial statements.

In November 2002, FASB issued Interpretation No. 45 (FIN No. 45), “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others,” which addresses the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under guarantees. FIN No. 45 also requires the recognition of a liability by a guarantor at the inception of certain guarantees that are entered into or modified after December 31, 2002. The additional disclosures required by FIN No. 45 have been included in the notes to our consolidated financial statements.

In addition to the other information in this report, the following risk factors should be carefully considered in evaluating our company and its business.

Our success depends on sales and continued innovation of our BIG-IP product line

For the fiscal year ended September 30, 2003, we derived 82.8% of our product revenues from sales of our BIG-IP product line. We expect to derive a significant portion of our net revenues from sales of our BIG-IP products in the future. Implementation of our strategy depends upon BIG-IP being able to solve critical network availability and performance problems of our customers. If BIG-IP is unable to solve these problems for our customers, or if we are unable to sustain the high levels of innovation in BIG-IP’s product feature set needed to maintain leadership in what will continue to be a competitive market environment, our business and results of operations will be harmed.

Our success depends on our timely development of new products and features and proper management of the timing of the life cycle of our products

We expect the secure application traffic management market to be characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. Our continued success depends on our ability to identify and develop new products and new features for our existing products to meet the demands of these changes, and for those products and features to be accepted by our existing and target customers. If we are unable to identify, develop and deploy new products and new product features on a timely basis, or if those products do not gain market acceptance, our business and results of operations may be harmed.

The current life cycle of our products is typically 12 to 24 months. The introduction of new products or product enhancements may shorten the life cycle of our existing products, or replace sales of some of our current products, thereby offsetting the benefit of even a successful product introduction, and may cause customers to defer purchasing our existing products in anticipation of the new products. This could harm our operating results by decreasing sales, increasing our inventory levels of older products and exposing us to greater risk of product obsolescence. We have also experienced, and may in the future experience, delays in developing and releasing new products and product enhancements. This has led to, and may in the future lead to, delayed sales, increased expenses and lower quarterly revenue than anticipated. Also, in the development of our products, we have experienced delays in the prototyping of our products, which in turn has led to delays in

product introductions. In addition, complexity and difficulties in managing product transitions at the end-of-life stage of a product can create excess inventory of components associated with the outgoing product that can lead to increased expenses. Any or all of the above problems could materially harm our business and operating results.

We may not be able to compete effectively in the emerging secure application traffic management market

The markets we serve are new, rapidly evolving and highly competitive, and we expect competition to persist and intensify in the future. Our principal competitors in the secure application traffic management market include Cisco Systems, Inc., Nortel Networks Corporation, Foundry Networks, Inc., NetScaler, Inc., Radware Ltd. and NetScreen Technologies, Inc. We expect to continue to face additional competition as new participants enter the traffic management market. In addition, larger companies with significant resources, brand recognition and sales channels may form alliances with or acquire competing traffic management solutions and emerge as significant competitors. Potential competitors may bundle their products or incorporate an Internet traffic management component into existing products in a manner that discourages users from purchasing our products. Potential customers may also choose to purchase additional or larger servers instead of our products.

Our quarterly and annual operating results are volatile and may cause our stock price to fluctuate

Our quarterly and annual operating results have varied significantly in the past and will vary significantly in the future, which makes it difficult for us to predict our future operating results. In particular, we anticipate that the size of customer orders may increase as we continue to focus on larger business accounts. A delay in the recognition of revenue, even from just one account, may have a significant negative impact on our results of operations for a given period. In the past, a majority of our sales have been realized near the end of a quarter. Accordingly, a delay in an anticipated sale past the end of a particular quarter may negatively impact our results of operations for that quarter, or in some cases, that year. Furthermore, we base our decisions regarding our operating expenses on anticipated revenue trends and our expense levels are relatively fixed. Consequently, if revenue levels fall below our expectations, our net income will decrease because only a small portion of our operating expenses vary with our revenues.

We believe that period-to-period comparisons of our results of operations are not meaningful and should not be relied upon as indicators of future performance. Our operating results may be below the expectations of securities analysts and investors in future quarters or years. Our failure to meet these expectations will likely harm the market price of our common stock.

We anticipate that the average selling prices of our products will decrease in the future in response to competitive pricing pressures, increased sales discounts, new product introductions by us or our competitors or other factors. Therefore, in order to maintain our gross profits, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our product costs. Our failure to do so will cause our net revenue and gross profits to decline, which will harm our business and results of operations. In addition, we may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices.

Our products have a lengthy sales cycle, which is difficult to predict. Historically, our sales cycle has ranged from approximately two to three months and has tended to lengthen as we have increasingly focused our sales efforts on the enterprise market. Also, as our distribution strategy has evolved into more of a channel model, utilizing value-added resellers, distributors and systems integrators, the level of variability in the length of sales cycle across transactions has increased and made it more difficult to predict the timing of many of our sales transactions. Sales of our BIG-IP and 3-DNS products require us to educate potential customers in their use and benefits. Sales of our products are subject to delays from the lengthy internal budgeting, approval and

competitive evaluation processes that large corporations and governmental entities may require. For example, customers frequently begin by evaluating our products on a limited basis and devote time and resources to testing our products before they decide whether or not to purchase. Customers may also defer orders as a result of anticipated releases of new products or enhancements by our competitors or us. As a result, our products have an unpredictable sales cycle that contributes to the uncertainty of our future operating results.

We rely on a third party contract manufacturer to assemble our products. We outsource the manufacturing of our hardware platforms to this contract manufacturer who assembles these hardware platforms to our specifications. We have experienced minor delays in shipments from contract manufacturers in the past. However, if we experience major delays in the future or other problems, such as inferior quality and insufficient quantity of product, any one or a combination of these factors may harm our business and results of operations. The inability of our contract manufacturer to provide us with adequate supplies of our products or the loss of our contract manufacturer may cause a delay in our ability to fulfill orders while we obtain a replacement manufacturer and may harm our business and results of operations. In particular, because we subcontract substantially all of our manufacturing to a single contract manufacturer, with whom we do not have a long-term contract, any termination, loss or impairment in our arrangement with this single source of hardware assembly, or any impairment of their facilities or operations, would harm our business, financial condition and results of operation.

If the demand for our products grows, we will need to increase our raw material and component purchases, contract manufacturing capacity and internal test and quality functions. Any disruptions in product flow may limit our revenue, may harm our competitive position and may result in additional costs or cancellation of orders by our customers.

We currently purchase several hardware components used in the assembly of our products from a number of single or limited sources. Lead times for these components vary significantly. Any interruption or delay in the supply of any of these hardware components, or the inability to procure a similar component from alternate sources at acceptable prices within a reasonable time, may delay assembly and sales of our products and, hence, our revenues, and may harm our business and results of operations.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure of confidential and proprietary information to protect our intellectual property rights. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

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. We are actively involved in disputes and licensing discussions with others regarding their claimed proprietary rights and cannot assure you that we will always successfully defend ourselves against such claims. If we are found to infringe the proprietary rights of others, or if we otherwise settle such claims, we could be compelled to pay damages or royalties and either obtain a license to those intellectual property rights or alter our products so that they no longer infringe upon such proprietary rights. Any license could be very expensive to obtain or may not be available at all. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. In addition, we have initiated, and may in the future initiate, claims or litigation against third parties for

infringement of our proprietary rights, including infringement of a patent we hold on our “cookie persistence” technology, to determine the scope and validity of our proprietary rights or those of our competitors. Any of these claims, whether claims that we are infringing the proprietary rights of others, or vice versa, with or without merit, may be time-consuming, result in costly litigation and diversion of technical and management personnel or require us to cease using infringing technology, develop non-infringing technology or enter into royalty or licensing agreements. Further, our license agreements typically require us to indemnify our customers and resellers for infringement actions related to our technology, which could cause us to become involved in infringement claims made against our customers or resellers. Any of the above-described circumstances relating to intellectual property rights disputes could result in our business and results of operations being harmed.

A change in accounting policies can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New pronouncements and varying interpretations of pronouncements have occurred with frequency and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business.

In particular, if we are required to record stock option grants as compensation expense on our income statement, our profitability may be reduced significantly. The current methodology for expensing such stock options is based on, among other things, the historical volatility of the underlying stock. Our stock price has been historically volatile. Therefore, the adoption of an accounting standard requiring companies to expense stock options would negatively impact our profitability and may adversely impact our stock price. In addition, the adoption of such a standard could limit our ability to continue to use stock options as an incentive and retention tool, which could, in turn, hurt our ability to recruit employees and retain existing employees.

Similarly, while we believe our current revenue recognition policies and practices are consistent with applicable accounting standards, current revenue recognition accounting standards, and accounting guidance with respect to such standards, are subject to change. Such changes could lead to unanticipated changes in our current revenue accounting practices, and such changes could significantly reduce our future revenues and earnings, which would likely have a material adverse effect on the price of our common stock.

We may not be able to sustain or develop new distribution relationships and a reduction or delay in sales to a significant distribution partner could hurt our business

Our sales strategy requires that we establish and maintain multiple distribution channels in the United States and internationally through leading industry resellers, original equipment manufacturers, or OEMs, systems integrators, Internet service providers and other channel partners. We have a limited number of agreements with companies in these channels, and we may not be able to increase our number of distribution relationships or maintain our existing relationships. If we are unable to establish and maintain our indirect sales channels, our business and results of operations will be harmed. In addition, one distributor of our products accounted for 12.6% of our net revenue for the fiscal year ended September 30, 2003. During the fiscal year ended September 30, 2002, no single reseller or customer accounted for more than 10% of our net revenue. A substantial reduction or delay in sales of our products to this or any other key distribution partner could harm our business, operating results and financial condition.

Software products frequently contain undetected errors when first introduced or as new versions are released. We have experienced these errors in the past in connection with new products and product upgrades. We expect that these errors will be found from time to time in new or enhanced products after commencement of commercial shipments. These problems may cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant

customer relations problems. We may also be subject to liability claims for damages related to product errors. While we carry insurance policies covering this type of liability, these policies may not provide sufficient protection should a claim be asserted. A material product liability claim may harm our business and results of operations.

Our products must successfully operate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of software errors, whether caused by our products or another vendor’s products, may result in the delay or loss of market acceptance of our products. The occurrence of any of these problems may harm our business and results of operations.

We intend to continue expanding into international markets. International sales represented 34.9% of our net revenues for the fiscal year ended September 30, 2003, 32.2% of our net revenues for the fiscal year ended September 30, 2002 and 33.3% of our net revenues for the fiscal year ended September 30, 2001. We have engaged sales personnel throughout Europe and the Asia Pacific region. Our continued growth will require further expansion of our international operations in the European, Asia Pacific and other markets. If we are unable to expand our international operations successfully and in a timely manner, our business and results of operations may be harmed. Such expansion may be more difficult or take longer than we anticipate, and we may not be able to successfully market, sell, deliver and support our products internationally.

Our operating results are exposed to risks associated with international commerce

As our international sales increase, our operating results become more exposed to international operating risks. These risks include risks related to potential recessions in economies outside the United States, foreign currency exchange rates, managing foreign sales offices, regulatory, political, or economic conditions in specific countries, military conflict or terrorist activities, changes in laws and tariffs, inadequate protection of intellectual property rights in foreign countries, foreign regulatory requirements, and natural disasters. All of these factors could have a material adverse effect on our business. In particular, in fiscal year 2003, we derived 13.8% of our total revenue from the Japanese market and this revenue is dependent on a number of factors outside our control, including the viability and success of our resellers and the strength of the Japanese economy, which has been weak in recent years.

Acquisitions, including our recent acquisition of substantially all of the assets of uRoam, Inc., present many risks and we may not realize the financial and strategic goals that are contemplated at the time of the transaction

With respect to our July 2003 acquisition of substantially all of the assets of uRoam, Inc., as well as any other future acquisitions we may undertake, we may find that the acquired assets do not further our business strategy as expected, or that we paid more than what the assets are later worth, or that economic conditions change, all of which may generate future impairment charges. There may be difficulty integrating the operations and personnel of the acquired business, and we may have difficulty retaining the key personnel of the acquired business. In the case of the assets acquired from uRoam, Inc., because it was based in Northern California and because the employees we hired in connection with the acquisition were not relocated to Seattle, the above-mentioned integration and personnel retention issues represent a particular risk to us. We may have difficulty in incorporating the acquired technologies or products with our existing product lines. Our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically and culturally diverse locations. We may have difficulty maintaining uniform standards, controls, procedures and policies across locations. We may experience significant problems or liabilities associated with the product quality, technology and other matters.

Our inability to successfully operate and integrate newly-acquired businesses appropriately, effectively and in a timely manner, or to retain key personnel of uRoam, Inc. or any other acquired business, could have a material adverse effect on our ability to take advantage of further growth in demand for integrated traffic

Our success depends on our key personnel and our ability to attract, train and retain qualified marketing and sales, professional services and customer support personnel

Our success depends to a significant degree upon the continued contributions of our key management, product development, sales, marketing and finance personnel, many of which may be difficult to replace. The complexity of our secure application traffic management products and their integration into existing networks and ongoing support, as well as the sophistication of our sales and marketing effort, requires us to retain highly trained professional services, customer support and sales personnel. In spite of the economic downturn, competition for qualified professional services, customer support and sales personnel in our industry is intense because of the limited number of people available with the necessary technical skills and understanding of our products. Our ability to retain and hire these personnel may be adversely affected by volatility or reductions in the price of our common stock, since these employees are generally granted stock options. The loss of services of any of our key personnel, the inability to retain and attract qualified personnel in the future or delays in hiring qualified personnel, may harm our business and results of operations.

We are a party to lawsuits in the normal course of our business. Litigation in general, and intellectual property and securities litigation in particular, can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. We believe that we have defenses in the lawsuits pending against us and we are vigorously contesting these allegations. Responding to the allegations has been, and probably will be, expensive and time-consuming for us. An unfavorable resolution of the lawsuits could adversely affect our business, results of operations, or financial condition.

Anti-takeover provisions could make it more difficult for a third party to acquire us

Our Board of Directors has the authority to issue up to 10,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. The rights of the holders of common stock may be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control of our company without further action by our stockholders and may adversely affect the voting and other rights of the holders of common stock. Further, certain provisions of our bylaws, including a provision limiting the ability of stockholders to raise matters at a meeting of stockholders without giving advance notice, may have the effect of delaying or preventing changes in control or management of our company, which could have an adverse effect on the market price of our common stock. In addition, our articles of incorporation provide for a staggered board, which may make it more difficult for a third party to gain control of our board of directors. Similarly, state anti-takeover laws in the State of Washington related to corporate takeovers may prevent or delay a change of control of our company.

Interest Rate Risk. Our cash equivalents consist of high-quality securities, as specified in our investment policy guidelines. The policy limits the amount of credit exposure to any one issue or issuer to a maximum of 20% of the total portfolio with the exception of treasury securities, commercial paper and money market funds, which are exempt from size limitation. The policy requires investments in securities that mature in two years or less, with the average maturity being one year or less. These securities are subject to interest rate risk and will decrease in value if interest rates increase. A decrease of one percent in the average interest would have resulted in a decrease of approximately $0.7 million in our interest income.

Foreign Currency Risk. The majority of our sales and expenses are denominated in U.S. dollars and as a result, we have not experienced significant foreign currency transaction gains and losses to date. While we have conducted some transactions in foreign currencies during the fiscal year ended September 30, 2003 and expect to continue to do so, we do not anticipate that foreign currency transaction gains or losses will be significant at our current level of operations. However, as we continue to expand our operations internationally, they may become significant in the future. We have not engaged in foreign currency hedging to date. However, we may do so in the future.

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of F5 Networks, Inc. and its subsidiaries at September 30, 2003 and 2002, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2003 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management; our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

The Company’s products and services are concentrated in highly competitive markets characterized by rapid technological advances, frequent changes in customer requirements and evolving regulatory requirements and industry standards. Failure to anticipate or respond adequately to technological advances, changes in customer requirements and changes in regulatory requirements or industry standards could have a material adverse effect on the Company’s business and operating results. Additionally, certain other factors could affect the Company’s future operating results and cause actual results to differ materially from expectations, including but not limited to, dependence on a third party manufacturer, difficulties in managing growth, difficulties in attracting and retaining qualified personnel, dependence on key personnel, enforcement of intellectual property rights, the lengthening of sales cycles and an uneven pattern of quarterly results.

The Company’s consolidated financial statements and accompanying notes are prepared on the accrual basis of accounting in accordance with generally accepted accounting principles in the United States of America.

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in accounting for revenue recognition, reserves for doubtful accounts, product returns, obsolete and excess inventory, warranties, valuation allowance on deferred tax assets and purchase price allocations. Actual results could differ from those estimates.

The Company considers all highly liquid investments with purchased maturities of three months or less to be cash equivalents. The Company invests its cash and cash equivalents in deposits with four major financial

institutions, which, at times, exceed federally insured limits. The Company has not experienced any losses on its cash and cash equivalents.

The Company classifies its investment securities as available for sale. Investment securities, consisting of corporate and municipal bonds and notes and United States government securities, are reported at fair value with the related unrealized gains and losses included as a component of shareholders’ equity. Realized gains and losses and declines in value of securities judged to be other than temporary are included in other income (expense). The cost of investments for purposes of computing realized and unrealized gains and losses is based on the specific identification method. Investments in securities with maturities of less than one year or where management’s intent is to use the investments to fund current operations are classified as short-term investments. Investments with maturities of greater than one year are classified as long-term investments.

The Company extends credit to customers and is therefore subject to credit risk. The Company performs initial and ongoing credit evaluations of its customers’ financial condition and does not require collateral. An allowance for doubtful accounts, in an amount based on historical levels, is recorded to account for potential bad debts. Estimates are used in determining the allowance for doubtful accounts and are based on a percentage of accounts receivable by aging category. In determining these percentages, the Company evaluates historical write-offs, and current trends in customer credit quality, as well as changes in credit policies.

The Company maintains its cash and investment balances with high credit quality financial institutions.

For certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, recorded amounts approximate fair market value, due to the short maturities of these instruments.

Short-term and long-term investments are recorded at fair value as the underlying securities are classified as available for sale and marked-to-market at each reporting period.

The Company outsources the manufacturing of its pre-configured hardware platforms to a contract manufacturer, who assembles each product to the Company’s specifications. As protection against component shortages and to provide replacement parts for its service teams, the Company also stocks limited supplies of certain key product components. Inventories consist of hardware and related component parts and are recorded at the lower of cost or market (as determined by the first-in, first-out method).

Restricted cash represents an escrow account established in connection with a lease agreement for the Company’s corporate headquarters. Under the terms of the lease, a $6.0 million certificate of deposit is required through November 2012, unless the lease is terminated prior to that date.

Property and equipment is stated at cost. Depreciation of property and equipment and amortization of capital leases are provided using the straight-line method over the estimated useful lives of the assets, ranging

from two to five years. Leasehold improvements are amortized over the lesser of the lease term or the estimated useful life of the improvements. The cost of normal maintenance and repairs is charged to expense as incurred and expenditures for major improvements are capitalized at cost. Gains or losses on the disposition of assets are reflected in the results of operations at the time of disposal.

Other assets primarily consist of software development costs and acquired technology.

Software development costs are charged to research and development expense until technological feasibility is established. Thereafter, until the product is released for sale, software development costs are capitalized and reported at the lower of unamortized cost or net realizable value of each product. The establishment of technological feasibility and the on-going assessment of recoverability of costs require considerable judgment by the Company with respect to certain internal and external factors, including, but not limited to, anticipated future gross product revenues, estimated economic life and changes in hardware and software technology. The Company amortizes capitalized software development costs using the straight-line method over the estimated economic life of the product, generally three years. During the years ended September 30, 2003 and 2002, the Company capitalized $474,000 and $392,000 of software development costs, respectively. Related amortization costs of $298,000 and $225,000 were recorded during the fiscal years 2003 and 2002, respectively.

Acquired technology is recorded at cost and amortized over its estimated useful life of five years. Acquired technology of $3.0 million was recorded in connection with the acquisition of uRoam, Inc. in July 2003. Amortization expense totaled approximately $100,000 for the year ended September 30, 2003.

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired as of the acquisition date. The Company has adopted the requirements of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS No. 142). SFAS No. 142 requires goodwill to be tested for impairment on an annual basis and between annual tests in certain circumstances, and written down when impaired. Goodwill of $24.2 million was recorded in connection with the acquisition of uRoam, Inc. in July 2003. There was no impairment of goodwill in fiscal year 2003.

The Company assesses the impairment of long-lived assets whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be recoverable. When such events occur, management determines whether there has been impairment by comparing the anticipated undiscounted net future cash flows to the related asset’s carrying value. If impairment exists, the asset is written down to its estimated fair value.

The Company recognizes revenue in accordance with the guidance provided under Statement of Position (SOP) No. 97-2, “Software Revenue Recognition,” and SOP No. 98-9 “Modification of SOP No. 97-2, Software Revenue Recognition, with Respect to Certain Transactions,” Statement of Financial Accounting Standards (SFAS) No. 48, “Revenue Recognition When Right of Return Exists,” and SEC Staff Accounting Bulleting (SAB) No. 101, “Revenue Recognition in Financial Statements.”

The Company sells products through resellers, original equipment manufacturers (OEMs) and other channel partners, as well as directly to end users. The Company recognizes product revenue upon shipment,

net of estimated returns, provided that collection is determined to be probable and no significant obligations remain. Product revenues from OEM agreements are recognized based on reporting of sales from the OEM partner.

Whenever a software license, hardware, installation and post-contract customer support (PCS) elements are combined into a package with a single “bundled” price, a portion of the sales price is allocated to each element of the bundled package based on their respective fair values as determined when the individual elements are sold separately. Revenues from the license of software are recognized when the software has been shipped and the customer is obligated to pay for the software. When rights of return are present and we cannot estimate returns, we recognize revenue when such rights of return lapse. Revenues for PCS are recognized on a straight-line basis over the service contract term. PCS includes rights to upgrades, when and if available, a limited period of telephone support, updates, and bug fixes. Installation revenue is recognized when the product has been installed at the customer’s site. Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and revenues are recognized when the consulting has been completed. Training revenue is recognized when the training has been completed.

Payment terms to domestic customers are generally net 30 days. Payment terms to international customers range from net 30 to 90 days based on normal and customary trade practices in the individual markets. The Company has offered extended payment terms to certain customers, in which case, revenue is recognized when payments become due.

In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, resellers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on the Company’s operating results or financial position.

The Company generally offers warranties of 90 days for hardware and one year for software, with the option of purchasing additional warranty coverage in increments of one year. The Company accrues for warranty costs as part of its cost of sales based on associated material product costs and technical support labor costs. During the years ended September 30, 2003, 2002 and 2001 warranty expense was $0.3 million, $1.6 million and $0.4 million, respectively. The following table summarizes the activity related to product warranties during fiscal years 2003 and 2002 (in thousands):

Research and development expenses consist of salaries and related benefits of product development personnel and an allocation of facilities and depreciation expense. Research and development expenses are reflected in the statement of operations as incurred.

Advertising costs are expensed as incurred. The Company incurred $1.0 million, $1.5 million and $1.5 million in advertising costs during the fiscal years 2003, 2002 and 2001, respectively.

The Company accounts for income taxes under the liability method of accounting. Under the liability method, deferred taxes are determined based on the differences between the financial statement and tax bases of assets and liabilities at enacted tax rates in effect in the year in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to estimated amounts expected to be realized.

The financial statements of all majority-owned subsidiaries have been translated into U.S. dollars in accordance with Statement of Financial Accounting Standards (SFAS) No. 52 “Foreign Currency Translation.” Accordingly, all assets and liabilities of the subsidiaries are translated at year-end exchange rates and all revenues and expenses are translated at the average exchange rate for the period presented. Translation gains and losses are reported as comprehensive income (loss) as a separate component of shareholders’ equity.

Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency, including US dollars. Gains and losses on those foreign currency transactions are included in determining net income or loss for the period of exchange. For the fiscal year ended September 30, 2003, a transaction loss of $544,000 was realized, with a transaction gain of $15,000 realized in fiscal year 2002. A transaction loss of $139,000 was charged to operations for the fiscal year ended September 30, 2001.

The Company complies with the requirements of Statement of Financial Accounting Standards (SFAS) No. 131, “Disclosure about Segments of an Enterprise and Related Information,” which establishes annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. Management has determined that the Company operates in one segment.

The Company accounts for stock-based employee compensation arrangements in accordance with the provisions of Accounting Principles Board Opinion No. 25 (APB No. 25), “Accounting for Stock Issued to Employees,” FASB Interpretation No. 44 (FIN No. 44), “Accounting for Certain Transactions Involving Stock Compensation,” and related interpretations and complies with the disclosure provisions of Statement of Financial Accounting Standards No. 123 (SFAS No. 123), “Accounting for Stock-Based Compensation.” Under APB No. 25, compensation expense is based on the difference, if any, on the date of the grant, between the deemed fair value of the Company’s stock and the exercise price of the option. The unearned compensation is being amortized in accordance with Financial Accounting Standards Board Interpretation No. 28 on an accelerated basis over the vesting period of the individual options. The Company accounts for

equity instruments issued to non-employees in accordance with the provisions of SFAS No. 123 and related interpretations.

The pro forma effect on the Company’s net income (loss) and net income (loss) per share of applying SFAS No. 123, utilizing the assumptions described in note 10 “Shareholders’ Equity,” would have been as follows (in thousands, except per share data):

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period.

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

Approximately 2.6 million of common shares potentially issuable from stock options for the year ended September 30, 2003 are excluded from the calculation of diluted earnings per share because the effect was antidilutive. For fiscal years 2002 and 2001, in which the Company incurred a net loss, all common stock equivalent shares are excluded from the calculation as their impact would have been antidilutive.

In April 2003, FASB issued Statement of Financial Accounting Standards No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities” (SFAS No. 149), which is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. SFAS No. 149 clarifies under what circumstances a contract with an initial net investment meets the characteristic of a derivative as discussed in Statement of Financial Accounting Standards No. 133, when a derivative contains a financing component, amends the definition of an “underlying” to conform it to the language used in FASB interpretation No. 45, “Guarantor Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” and amends certain other existing pronouncements. The adoption of this standard did not have an impact on our consolidated financial statements.

In January 2003, FASB issued Interpretation No. 46 (FIN No. 46), “Consolidation of Variable Interest Entities,” which addresses consolidation by business enterprises of variable interest entities that either: (1) do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) the Company will hold a significant variable interest in, or have significant involvement with, an existing variable interest entity. The adoption of this interpretation did not have an impact on our consolidated financial statements.

Certain reclassifications have been made to prior year balances to conform to the current year presentation. These reclassifications had no impact on previously reported net loss, shareholders equity or cash flows.

The cost or amortized cost and fair value of fixed maturities at September 30, 2003, by contractual years-to-maturity, are presented below (in thousands):

In December 2001, the Company purchased approximately 16 million shares of common stock of Artel Solutions Group Holdings Limited, or Artel, which represented an approximate 1% ownership percentage of that company. The Company sold its investment in Artel and recorded a loss on disposition of $263,000 during the fourth quarter of fiscal year 2003.

The Company is contractually obligated to purchase component inventory that its contract manufacturer procures in accordance with a forecast, unless the Company gives notice of order cancellation within applicable lead times. For any completed product inventory carried by the contract manufacturer beyond 30 days, the Company will be charged a monthly carrying fee of 1.5%. Alternatively, the Company has the option to purchase inventory held by the contractor manufacturer beyond 30 days to avoid incurring related carrying charges. As of September 30, 2003, the Company was committed to purchase approximately $3.3 million of such inventory within the following quarter.

Depreciation and amortization expense totaled approximately $4.7 million, $5.4 million, and $5.3 million for the fiscal years ended September 30, 2003, 2002 and 2001, respectively.

On July 23, 2003, the Company acquired substantially all of the assets and assumed certain liabilities of uRoam, Inc. (uRoam) for cash of $25.0 million. The Company also incurred $2.4 million of direct transaction costs for a total purchase price of $27.4 million. uRoam’s FirePass server is a comprehensive remote access product that enables users to access applications in a secure fashion using industry standard Secured Socket Layer (SSL) technology. The acquisition of substantially all the assets of uRoam is intended to allow the Company to quickly enter the SSL Virtual Private Network market, broaden its customer base and augment the existing product line. The Company has hired substantially all of uRoam’s 20 employees, consisting of product development, sales and service personnel.

The Company accounted for the acquisition under the purchase method of accounting in accordance with SFAS No. 141, “Business Combinations.” Under the purchase method of accounting, the total purchase price was allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values. The excess of the purchase price over those fair values was recorded as goodwill. The fair value assigned to the tangible and intangible assets acquired and liabilities assumed were based on estimates and assumptions provided by management, and other information compiled by management, including an independent valuation, prepared by an independent valuation specialist that utilized established valuation techniques appropriate for the technology industry.

To determine the value of the developed technology, a combination of cost and market approaches were used. The cost approach required an estimation of the costs required to reproduce the acquired technology. The market approach measures the fair value of the technology through an analysis of recent comparable transactions. The $3.0 million allocated to developed technology is being amortized using the straight-line method over an estimated useful life of five years. The $24.2 million allocated to goodwill will not be amortized but will be subject to at least an annual impairment test under the requirements of Statement of Financial Accounting Standards No. 142 “Goodwill and other Intangible Assets.”

The following unaudited pro forma condensed combined consolidated summary financial information has been derived by the application of pro forma adjustments to the historical consolidated financial statements of F5 Networks and uRoam. Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with these unaudited pro forma condensed combined consolidated summary financial information.

The unaudited pro forma condensed combined consolidated summary financial information combines the consolidated statement of operations of F5 Networks for the year ended September 30, 2003 with uRoam’s unaudited statement of operations for the nine months ended June 30, 2003 and the unaudited statement of operations for the period July 1, 2003 through July 23, 2003, the effective date of the uRoam acquisition, as if the acquisition had been completed at the beginning of the year.

The unaudited pro forma condensed combined consolidated summary financial information for the year ended September 30, 2002 combines the consolidated statement of operations of F5 Networks for the fiscal year ended September 30, 2002 with uRoam’s consolidated statement of operations for the calendar year ended December 31, 2002.

Amortization expense related to other assets was approximately $412,000 and $231,000 for the fiscal years ended September 30, 2003 and 2002, respectively. There was no amortization expense related to other assets for the fiscal year ended September 30, 2001.

Estimated amortization expense for the five succeeding fiscal years is as follows (in thousands):

During the third quarter of fiscal year 2002, the Company recorded restructuring charges of approximately $2.8 million in connection with management’s decision to exit the cache appliance business. As a result of discontinuing this line of business and other changes in the overall business, the Company wrote-down certain assets, consolidated operations, and terminated 47 employees throughout all divisions of the company. An additional charge of $503,000 related to employee separation costs was recorded in July 2002, resulting in total restructuring charges of $3.3 million for the fiscal year 2002. As of September 30, 2002, total cash payments and write-offs of approximately $2.2 million had been recorded.

The following table summarizes the movements in the remaining restructuring charge liabilities (in thousands):

As part of the restructuring, excess facilities costs were determined to be $1.0 million. These costs are the result of the decision to exit a support facility in Washington DC. The estimated facilities costs were based on current comparable rates for leases in the respective market. In April 2003, the excess facilities were subleased at the then current market value through the term of the lease. The difference between the lease payments and sublease income will be applied against the restructuring liability until expiration of the lease in 2007.

During the first fiscal quarter of 2001, the Company recorded a restructuring charge totalling approximately $1.1 million in connection with management’s decision to bring operating expenses in line with the business revenue growth model. Accordingly, the Company terminated 96 employees throughout all divisions of the Company. By the end of January 2001, all identified employees had been terminated. During the quarter ended March 31, 2001, the Company reversed $96,000 of the original accrual due to a revision of previous estimates. As of September 30, 2001, substantially all of the restructuring charge accrued for during the first quarter of 2001 had been paid.

The Company’s deferred tax assets include net operating loss carry forwards of approximately $61.1 million; $52.5 million related to U.S. operations and $8.6 million related to United Kingdom operations. The United States net operating loss carry forwards will begin to expire in fiscal year 2011 through 2023. The United Kingdom net operating loss carries forward indefinitely. The Company also has Research and Experimentation Credit carry forwards which will begin to expire in fiscal year 2011 through 2023.

The fair value of each option is estimated at the date of grant using the following weighted-average assumptions:

In May 1999, the board of directors approved the adoption of the 1999 Employee Stock Purchase Plan (the Employee Stock Purchase Plan). A total of 1,000,000 shares of common stock have been reserved for issuance under the Employee Stock Purchase Plan.

In July and August 2001, a series of putative securities class action lawsuits were filed in United States District Court, Southern District of New York against certain investment banking firms that underwrote the Company’s initial and secondary public offerings, the Company and some of the Company’s officers and directors. These cases, which have been consolidated under In re. F5 Networks, Inc. Initial Public Offering Securities Litigation, No. 01 CV 7055, assert that the registration statements for the Company’s June 4, 1999 initial public offering and September 30, 1999 secondary offering failed to disclose certain alleged improper actions by the underwriters for the offerings. The consolidated, amended complaint alleges claims against the Company and those of our officers and directors named in the complaint under Sections 11 and 15 of the Securities Act of 1933, and under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. Other lawsuits have been filed making similar allegations regarding the public offerings of more than 300 other companies. All of these various consolidated cases have been coordinated for pretrial purposes as In re. Initial Public Offering Securities Litigation, Civil Action No. 21-MC-92. In October 2002, the directors and officers were dismissed without prejudice. The issuer defendants filed a coordinated motion to dismiss these lawsuits in July 2002, which the Court granted in part and denied in part in an order dated February 19, 2003. The Court declined to dismiss the Section 11 and Section 10(b) and Rule 10b-5 claims against the Company. In June 2003, a proposal was made for the settlement and release of claims against the issuer defendants and their directors and officers, including us, in exchange for a guaranteed recovery to be paid by the issuer defendants’ insurance carriers and an assignment of certain claims against the underwriters. The settlement is subject to a number of conditions, including approval by the proposed settling parties and the Court. If the settlement does not occur, and litigation against us continues, we believe we have meritorious defenses and intend to defend the case vigorously. Securities class action litigation could result in substantial costs and divert our management’s attention and resources. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of the litigation, and any unfavorable outcome could have a material adverse impact on our business, financial condition and operating results.

infringe third-party trademarks and other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

In October 2000, the Company extended a loan to an executive officer and his wife, in the principal amount of $350,000, in order to facilitate the purchase of a residence in the Seattle area. On March 15, 2002, payments due under the note were extended for a period of one year, as allowed per the terms of the note. This loan is evidenced by a promissory note, the principal of which is payable in three equal installments, together with accrued interest, on March 31, 2002, March 31, 2003, and March 31, 2004, or immediately upon the sale of the residence or termination of the officer’s employment. Interest accrues on the loan at the rate of 6% per annum. The balance of the loan totaled $240,354 at September 30, 2003. The residence was sold in October 2003 and the loan was repaid in full on October 20, 2003.

The Company has a 401(k) savings plan whereby eligible employees may voluntarily contribute a percentage of their compensation. The Company may, at its discretion, match a portion of the employees’ eligible contributions. Contributions by the Company to the plan during the years ended September 30, 2003, 2002, and 2001 were approximately $852,000, $950,000, and $953,000, respectively.

The Company’s customers are in diverse industries and geographic locations. Net revenues from international customers are primarily denominated in U.S. Dollars and totaled approximately $40.5 million, $34.8 million, and $35.0 million for the years ended September 30, 2003, 2002 and 2001, respectively. One domestic distributor accounted for 12.6% of total net revenue for fiscal year 2003. This distributor accounted for 17.8% of accounts receivable as of September 30, 2003. During the years ended September 30, 2002 and 2001, no single reseller or customer exceeded 10% of the Company’s net revenue or accounts receivable balance.

The following presents the Company’s unaudited quarterly results of operations for the eight quarters ended September 30, 2003.

(1)	During the fourth quarter of fiscal year 2003, the Company reversed a $250 reserve initially established for an amount considered potentially uncollectible. The amount was recovered pursuant to a settlement agreement and the reversal of the reserve was recorded as a credit to general and administrative expenses.

As of September 30, 2003, we carried out an evaluation, under the supervision and with the participation of the Company’s management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e) and 15d-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures are effective to timely alert them to any material information relating to the Company (including its consolidated subsidiaries) that must be included in our periodic SEC filings. There have been no significant changes in the Company’s internal controls or in other factors that could significantly affect internal controls subsequent to their evaluation.

We intend to review and evaluate the design and effectiveness of our disclosure controls and procedures on an ongoing basis and to improve our controls and procedures over time and to correct any deficiencies that we may discover in the future. Our goal is to ensure that our senior management has timely access to all material financial and non-financial information concerning our business. While we believe the present design of our disclosure controls and procedures is effective to achieve our goal, future events affecting our business may cause us to modify our disclosure controls and procedures.

	The average selling price of our products may decrease and our costs may increase, which may negatively impact gross profits


	It is difficult to predict our future operating results because we have an unpredictable sales cycle


	Our business may be harmed if our contract manufacturer is not able to provide us with adequate supplies of our products or if this single source of hardware assembly is lost or impaired


	Our business could suffer if there are any interruptions or delays in the supply of hardware components from our third-party sources


	We may not adequately protect our intellectual property and our products may infringe on the intellectual property rights of third parties


	Future changes in financial accounting standards or our revenue recognition policies may cause adverse unexpected revenue fluctuations and affect our reported results of operations
