Strategy and Priorities

Nearly all organizations today find themselves at the convergence of two significant trends: the evolution of applications as the center of their businesses and their customers’ digital lives and the escalation of threats against those applications. This presents a tremendous challenge as many companies now manage complex application portfolios comprising older legacy and newer modern technologies and infrastructures. In our 2022 State of Application Strategy Report, 88 percent of organizations said they operate both legacy and modern application architectures, and 70 percent operate in multiple clouds. These hybrid

Table of Contents

environments create operational complexity and expand the threat surface area as companies are forced to deploy separate, and often inconsistent, security controls across different environments.

Over the past several years, F5 has transformed its business and significantly expanded its software and cloud offerings to deliver a broad portfolio of solutions to help customers address the complexity and risk in today’s hybrid IT environments. Through BIG-IP, F5 NGINX, and F5 Distributed Cloud Services, F5 offers a range of integrated, machine learning-driven solutions that protect legacy and modern applications and APIs across data center, cloud, and edge locations.

Our multi-cloud application security and delivery solutions reduce our customers’ operational complexity and costs, enabling our customers to scale, secure, and optimize both legacy and modern applications, across any infrastructure and create extraordinary digital experiences for their end users. We are leveraging near real-time collection of live application telemetry, machine learning and artificial intelligence, and toolchain automation to create adaptive applications capable of rapidly responding to changes in performance, availability, and security threats with little to no human interaction.

Key components of our strategy include:

Bringing our adaptive application vision to life

F5 is uniquely positioned to deliver adaptive applications. Through our organic innovation and inorganic investments, we have created the broadest portfolio of multi-cloud application security and delivery technologies in the market. We are able to support our customers’ modern and legacy application security and delivery needs across any environment, with the flexibility of multiple deployment models including hardware, software, and SaaS offerings. F5 is continuing to converge our application security and delivery capabilities on our recently launched F5 Distributed Cloud Services platform, unifying policy declaration, enabling broader telemetry, and driving significant automation. Doing so will dramatically simplify application creation, deployment and management for our customers, reducing the time it takes to turn up and repair applications while lowering total cost of ownership, through a SaaS-based consumption model.

Transforming how customers experience F5

As we expand the role we play for our customers, we are also transforming how our customers experience F5. Our goal is to create a unified and frictionless F5 experience for our customers. Over the last several years, we have made it easier for our customers to procure, deploy, manage, and upgrade our technologies. We also have taken steps to integrate the customer experience across our growing portfolio by simplifying product naming and rebranding several acquired and integrated solutions as part of our F5 Distributed Cloud Services platform.

Going forward we will leverage and grow our foundational capabilities in data and insights, digital sales, and SaaS-delivered capabilities to deliver consistent world-class customer experiences, including simple, integrated and friction-free consumption of our technologies. We will continue to improve customer awareness and understanding of F5’s expanded portfolio with a focus on buying personas and business needs and intend to enhance our digital customer experiences to deliver both growth and efficiency.

Capturing growth in security and software

In the previous decade, our customers were focused on protecting their networks from attack. Today, attackers are targeting applications with threats like malware, bots, and API penetration. Through both organic and inorganic investment, we have expanded our application security portfolio and the deployment models through which customers can consume our solutions. F5’s leading security capabilities combined with our multi-cloud approach enables our customers to deploy a consistent security posture across their entire application estate.

In fiscal year 2022 we announced a major expansion of our security and delivery portfolio with the launch of F5 Distributed Cloud Services. This platform integrates F5 capabilities and recently acquired technologies to deliver security, multi-cloud networking and edge-based computing solutions on a unified SaaS platform.

Our first solution for the platform, F5 Distributed Cloud WAAP (“Web Application Firewall and API Protection”), augments multiple security capabilities across F5 technologies enabling our customers to deploy advanced security, and unify and consistently manage policies while providing visibility into the enterprise security stature across all environments where the solution is deployed.

Beyond delivering security capabilities via multiple deployment models including hardware, software and SaaS, we continue to innovate across our software offerings including improving automation and orchestration in our BIG-IP software, and advancing the capabilities of our F5 NGINX solution.

Corporate Functions

Customer Services and Technical Support

In connection with our products, we offer a broad range of professional services including consulting, training, installation, maintenance, and other technical support services.

We believe that our ability to provide consistent, high-quality customer service and technical support is a key factor in attracting and retaining large enterprise and service provider customers. Accordingly, we offer a broad range of support services that includes installation, phone and online technical support, hardware repair and replacement, software updates, online tools, consulting, and training services.

We provide these services directly to customers and also utilize a multi-tiered support model, leveraging the capabilities of our channel partners. Our technical support staff is strategically located in regional service centers to support our global customer base.

Product Development

We believe our future success depends on our ability to maintain technology leadership by continuing to innovate and to improve our products and by developing new products to meet the changing needs of our customers and partners. Our engineering organization uses standard processes for the development, documentation, and quality control of services, software, and systems that are designed to meet these goals. These processes include working with our business development and marketing teams, customers, and partners to identify technology innovation opportunities to better meet the evolving needs of our addressable markets.

Over 90 percent of our engineers are engaged in software, SaaS, and managed services development in several major locations including Seattle, Washington; Hyderabad, India; Tel Aviv, Israel; San Jose and San Francisco, California; and Cork, Ireland.

Our hardware engineering team is located in Spokane, Washington; San Jose, California; and Tel Aviv, Israel.

Smaller development sites including Boulder, Colorado; Warsaw, Poland; and Billerica, Massachusetts also support the core development teams in the larger centers.

Members of all our engineering teams collaborate closely with one another to ensure the interoperability and performance of our solutions.

We believe that robust and constant innovation is a necessity for F5, so we are also innovating in new ways. We have had dedicated teams focused on testing new disruptive innovations in technology, business models, or customer segments. We expect innovations resulting from the work of these teams will be complementary to our goal of delivering the broadest and most consistent portfolio of solutions across cloud and on-premises environments.

We rely on a combination of patent, copyright, trademark, and trade secret laws and restrictions on disclosure to protect our intellectual property rights. F5 holds 469 patents in the United States and has 66 international patents (with 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

Table of Contents

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 the laws of the United States. Any issued patent may not preserve our proprietary position, and competitors or others may 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 are generally term licenses which may renew annually and that generally provide for certain rights and licenses to support our customers post termination. While we may not be able to renew all of these licenses in the future, we believe that alternative technologies for these licenses are available both domestically and internationally.

During the fiscal years ended September 30, 2022, 2021 and 2020, we had research and product development expenses of $543.4 million, $512.6 million, and $441.3 million, respectively.

Sales and Marketing

Our customers include a wide variety of enterprises and service providers among Fortune 1000 and Business Week Global 1000 companies, including those in technology, telecommunications, financial services, transportation, education, manufacturing, healthcare, and government. In fiscal year 2022, sales outside of the Americas represented 41.7% of our net revenues. Refer to Note 15 of our consolidated financial statements included in this Annual Report on Form 10-K for additional information regarding our revenues by geographic area.

Sales

We sell our products and services to large and medium enterprise customers, including federal government entities, financial services customers and service providers through a variety of routes to market and channels. Our sales teams sell our products and services directly to customers by working closely with our channel partners including distributors, value-added resellers (“VARs”), managed service providers (“MSPs”), and systems integrators.

F5 sales teams. Our inside sales team generates and qualifies leads from marketing and helps manage accounts by serving as a liaison between the field and internal corporate resources. Our outside sales team works directly with partners and customers across the globe. Our field sales personnel are located in major cities in three sales regions: the Americas (primarily the United States); EMEA; and APAC. Field sales personnel work closely with our channel partners to sell our products and services to their customers. We reward partners that identify new business and provide sales expertise for our portfolio of products and solutions through various incentive programs. Systems engineers, with deep technical domain expertise, support our regional sales account managers and channel partners providing pre-sale technical solution engineering and support, as needed.

Distributors, VARs, and MSPs. As a key component of our sales strategy, we have established relationships with a number of large national and international distributors, local and specialized distributors, VARs, and MSPs. We derive a majority of our product sales from VARs and MSPs, relying on our large distributors for fulfillment, training, and partner enablement.

Our agreements with our channel partners are not exclusive and do not prevent them from selling competitive products. These agreements typically have one-year terms with no obligation to renew, and typically do not provide for exclusive sales territories or minimum purchase requirements.

For fiscal year 2022, sales to two of our worldwide distributors, Ingram Micro, Inc. and Synnex Corporation represented 20.0% and 13.4% of our total revenues, respectively. Our agreements with distributors are standard, non-exclusive distribution agreements that renew automatically on an annual basis and generally can be terminated by either party with 90 days written notice prior to the start of any renewal term. The agreements grant certain distributors the right to distribute our products to resellers, with no minimum purchase requirements.

Systems integrators. We also market our products through strategic relationships with systems integrators, including Dell Services, DXC, HP Enterprise Services, and IBM Global Services, who include our products as core components of application deployments or network-based solutions they deploy for their customers. In most cases, systems integrators do not directly purchase our products for resale to their customers. Instead, they typically recommend and/or manage our products as a part of broader solutions supporting enterprise applications and internet facing systems that incorporate our technology for security, high availability, and enhanced performance.

Resellers and technology partners. Historically, our ability to compete with much larger companies has been strengthened through partnerships with large systems and software vendors. Currently, we partner with many technology

Table of Contents

partners and public cloud providers who resell our products. We have ongoing partnerships with the major cloud providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform and have expanded our reseller routes to market to include their public cloud marketplaces. F5 has recently signed a Strategic Collaboration Agreement (“SCA”) with AWS and are actively engaged with Microsoft Azure on private offers levering our software on Azure. Our business development team manages these relationships and closely monitors adjacent and complementary markets for opportunities to partner with those whose solutions are complementary to ours and could enable us to expand our addressable market.

Marketing

As we continue to expand our offerings and advance our range of consumption models (e.g., from on-premises to SaaS-based), we are focused on driving the compelling and unique value proposition of F5 among our existing customers as well as new buying centers. In addition to revitalizing our brand in the market, our expansion into new buying centers among existing customers (DevOps for example), exploration of new routes to market (such as public cloud marketplaces), and acquisition of a host of net new customers, compel us to increase our focus and investments in more digitally enabled, personalized and frictionless experiences at scale.

We are maintaining our efforts to drive momentum of our brand and reputation to deliver clarity, guidance and inspiration among our existing customers, future customers, partners, and employees around our evolving strategy behind F5’s unique offering. Additionally, to best support our growth as we transform our role in driving value for our customers, we are transforming marketing from a cost center to a revenue center to serve as a meaningful and predictable source of opportunities, customer growth and revenues. The critical success factors in this shift are increased investments in digital technologies, deep focus on the customer experience at every touchpoint, and shifting our culture to adopt an agile mindset as we use data to constantly improve our contributions to our customers and ultimately our shareholders.

Manufacturing

We outsource the manufacturing of our pre-configured hardware platforms to a third-party contract manufacturer, Flex Ltd. ("Flex"), for building, assembling, and testing according to our specifications at Flex's facilities in Guadalajara, Mexico and Zhuhai, China. Flex also performs the following activities on our behalf: material procurement, PCB assembly and test, final assembly, system test, quality control, and direct shipment.

We provide a rolling forecast that allows Flex to stock component parts and other materials, plan capacity, and build finished goods inventory in anticipation of end-user demand. Flex procures components in volumes consistent with our forecast, assembles the products, and tests them according to our specifications. Generally, we do not own the system components. Hardware components for our products consist primarily of commodity parts and certain custom components. Many of our components are purchased from sources which we believe are readily available from other suppliers. However, 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 and are increasing in light of global shortages of critical components. Global supply chain constraints continue to decrease our visibility into component availability and lead times even for commodity components. Per the terms and conditions with our agreement with Flex , if the components are unused or the products are not sold within specified periods of time, we may incur carrying charges or obsolete material charges for components that our contract manufacturers purchased to build products to meet our forecast or customer orders.

Systems built in Guadalajara are shipped to the Flex fulfillment center in Milpitas, California for distribution primarily to distributors, value-added resellers, or end users in EMEA and the Americas. Systems built and fulfilled in Zhuhai are for distribution to partners and customers in APAC. Title to the products transfers from Flex to us and then to our customers upon shipment from a designated fulfillment location.

Backlog

Backlog is primarily systems-based and represents orders confirmed with a purchase order for products to be fulfilled and invoiced to customers with approved credit status. Orders are subject to cancellation, rescheduling by customers, or product specification changes by customers. Although we believe that the backlog orders are firm, purchase orders may be canceled by the customer prior to fulfillment without significant penalty. For this reason, we believe that our product backlog at any given date is not a reliable indicator of future revenues. At the end of fiscal year 2022, we had product backlog of approximately $231 million.

Human Capital Management

F5’s commitment to its employees is to be one global and diverse team that is both human-first and high-performance and to attract and grow amazing talent. This commitment is delivered through our culture and engagement, our investment in

Table of Contents

employees’ growth and development, our focus on diversity and inclusion, and in our compensation, benefits, and wellbeing offerings.

Employees

As of September 30, 2022, we had 7,089 employees – over 99% of whom were full time employees. Our employees are in 46 countries with 50% of employees in the United States. None of our employees in the United States are represented by a labor union. We have experienced no work stoppages and believe that our employee relations are in good standing, as evidenced by our bi-annual employee engagement survey results and described in the section below entitled Culture and Engagement.

Culture and Engagement

We have been able to sustain our strong company culture in a hybrid work model thanks to increased focus on continuously embedding BeF5 behaviors and LeadF5 principles into our systems, processes, decisions, and conversations. We are constantly reinforcing, rewarding, and recognizing desired behaviors to send the message that they are key to executing on our strategy.

We measure the success of and identify areas of improvement for our company culture through global surveys of employee experience and sentiment at least twice each year. As of June 2022, employees reported high satisfaction with F5’s culture on several key questions:

• 95% of employees favorably rate “F5 has demonstrated that employee well-being and health is a priority during the coronavirus outbreak."

• 91% of employees favorably rate “I am proud to work for F5."

• 91% of employees favorably rate “At F5, employees are treated equally and fairly regardless of their background.”

• 90% of employees favorably rate “F5 has a great culture."

• 84% of employees favorably rate “I feel a sense of belonging at F5.”

Additionally, F5 is a recognized Great Place to Work 2022 in both India and the United States and was awarded the Bestie 2022 award by Benevity.

Growth and Development

We provide employees with opportunities to improve their technical and professional knowledge, better understand our business and products, strengthen management and leadership, as well as maintain our high standards of business integrity through ongoing compliance training. These development opportunities include live events on quarterly “Learning Days” dedicated to learning and exploring new ideas; learning paths created to support specific areas of knowledge, including deepening their knowledge of BeF5 and LeadF5; leadership coaching, which matches participants with an expert external coach; a global mentoring program; and a sponsorship program which provides several hundred employees a year with customized professional and personal development. Employees also have access to multiple third-party resources to enhance the learning opportunities developed internally. In a competitive market for talent, investing in growth and development at F5 remains a key differentiator for our employee recruitment and retention.

Diversity and Inclusion

F5 believes our differences—when embraced with humility and respect—drive smarter decisions, increased innovation, stronger performance, and a culture where everyone can be themselves and reach their full potential.

Table of Contents

At F5, we are committed to creating a more diverse and inclusive workplace. Our strategic framework is called “IDEA”: Inclusion, Diversity, Equity and Allyship. Each concept in IDEA requires focus and engagement at all levels of the organization and to be embedded into our ways of working. (For more information, please see the “Open House Report” at F5.com/company/diversity-inclusion).

To increase inclusion at F5, we foster communities through our Employee Inclusion Groups (“EIGs”) – F5 Ability, F5 Appreciates Blackness, F5 Connects Women, F5 Latinx e Hispanos Unidos, F5 Military Veterans, F5 Multicultural and F5 Pride – bringing people together across F5 and around the world. All seven EIGs are led by employees, with a dedicated annual budget and executive sponsor. F5’s EIG leaders partner with the Company’s Diversity & Inclusion team to cultivate personal and professional growth amongst their members. Our EIG leaders’ efforts to build a thriving community of diverse individuals at F5 are recognized through quarterly bonuses.

Our diversity as a company is advanced by the steady increase in our transparency on the actions and the accompanying progress we have made to build a culture of belonging and representation. F5 will release the results of the Company’s first diversity representation and employee inclusion score metrics to the short-term cash incentive program for the Company’s executives in the Proxy Statement for fiscal year 2022.

To increase equity in opportunities across F5, we hosted our biennial development conference focused on leadership development and targeting our Black and Latinx communities within F5. This year’s conference tripled the number of attendees and had a satisfaction rating of 4.6 out of 5. Replays of several of the conference’s speakers are available for public viewing on F5’s YouTube channel.

Allyship is critical to the sustainability of our diversity and inclusion program at F5. We hosted an allyship track at our conference and launched micro-trainings across our workforce and around the world. Each month, content is made available to the allyship community to deepen their understanding of experiences different from their own and gain new skills to help speak up and be an active participant in creating a more diverse and inclusive F5.

Compensation, Benefits and Wellbeing

F5 offers a competitive Total Rewards package intended to attract, retain, and motivate our employees guided by our human-first approach. Our package includes market-competitive pay, incentive plans, restricted stock unit grants (“RSUs”), an Employee Stock Purchase Plan, retirement plans, healthcare, paid time off and family leave. We continue to evaluate and enhance our programs to support the diverse needs of our employees’ overall health and wellbeing. We continue our Freedom to Flex program allowing employee choice to work fully remote, hybrid, or full time in an F5 office. The flexibility in hiring remote workers is another element that supports our ability to attract diverse talent. This and related programs resulted in our COVID-19 global pandemic response being among the highest rated categories on our global employee survey.

One key program we have maintained and expanded to support our employees’ wellbeing are four wellness weekends when once a quarter all employees have a set Friday through Monday off. This program allows F5 employees to collectively take time off to relax, recharge, and focus on wellness without worry of coming back to an over-loaded inbox. In addition, in fiscal year 2022, we expanded in the United States our healthcare travel reimbursement to assist our employees’ access to certain covered medical procedures that may be unavailable in their state of residence, increased our fertility and adoption assistance benefits, and added Juneteenth as a company holiday in the United States.

The mental wellbeing of our employees remains a very important area of focus. F5 has made and continues to make significant investments in tools and programs to address employee mental health. Such investments include a paid subscription to a meditation app for all global employees, mental health awareness training provided to managers (also attended by our Executive Leadership Team), and the removal of out-of-network penalties for therapy visits on our United States medical plans - which also opened up greater access to diverse therapists.

Environmental, Social & Governance

At F5, we care deeply not just about what we do, but how we do it. We consider this our “human-first” approach to the way we conduct our business, and it is reflected in our expanded commitment to Environmental, Social and Governance (“ESG”) – extending from the environmental sustainability of our products and operations to the well-being of our employees and our communities.

Environmental. Since F5 formed the ESG team in fiscal year 2021, the focus has been on bringing the environmental program at the Company up to the standards we are proud to have set over the last 28 years in social and governance. In fiscal year 2022, F5 took its first step towards a climate target; committing to reduce our absolute scope 1 and 2 emissions 50% by

Table of Contents

2030 from a 2021 baseline year. We will complete our Scope 3 emissions inventory across our value chain, to issue our complete science-based target with the Science Based Target Initiative by the close of fiscal year 2023.

To start taking immediate action on our target, F5 made its first-ever purchase of renewable energy certificates in fiscal year 2022. We focused on buying renewable energy in the Western region of the United States first, given that our highest volume of emissions worldwide is currently concentrated around our headquarters in Seattle, WA and offices in Spokane, WA and San Jose, CA.

Social. In addition to the employee programs and benefits outlined in the Human Capital Management section above, we continue to prioritize F5 Global Good, the community development initiative that amplifies our employee engagement and diversity and inclusion programs. In fiscal year 2022, more than half of all worldwide employees participated in Global Good programs, volunteering over 7,200 hours and directing the entirety of F5’s donations, through both the Company matching program and grant selection committees. F5 and its employees donated over $4.6 million to over 3,000 non-profits worldwide in fiscal year 2022.

Governance. Our guiding principle to do the right thing for each other, our customers, our shareholders, and our communities is set forth in F5’s Code of Business Conduct and Ethics, compliance training programs and most importantly, in the behaviors and principles we measure all employees on: BeF5 and LeadF5.

In fiscal year 2022, F5 bolstered the governance of the working and environmental conditions in our supply chain by joining the Responsible Business Alliance.

The oversight of our ESG programs is conducted by the Nominating and ESG Committee of the Board of Directors, where ESG strategy, disclosures and metrics are reviewed each quarter. In addition, in fiscal year 2022, the Talent and Compensation Committee of the Board introduced additional ESG metrics to the short-term cash incentive program for the Company’s executives in the form of measurements related to year-over-year increases in diversity representation and measurement of employee inclusion.

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

Our business could be adversely impacted by conditions affecting the information technology market

A substantial portion of our business depends on the demand for information technology by large enterprise customers and service providers. We are dependent upon the overall economic health of our current and prospective customers and the continued growth and evolution of the Internet. International, national, regional and local economic conditions, such as recessionary economic cycles, protracted economic slowdown or further deterioration of the economy could adversely impact demand for our products. Demand for our products and services depends substantially upon the general demand for application delivery products and associated services, which fluctuates based on numerous factors, including capital spending levels and growth of our current and prospective customers, as well as general economic conditions. Moreover, the purchase of our products is often discretionary and may involve a significant commitment of capital and other resources. Future economic projections for the information technology sector are uncertain as companies continue to reassess their spending for technology projects and embrace new models for delivery of IT services, such as cloud computing and highly orchestrated software defined networking environments. As a result, spending priorities for our current and future customers may vary and demand for our products and services may be impacted. In addition, customer buying patterns are changing over time and more customers seek to rent software on a subscription basis and to reduce their total cost of ownership. These evolving business models could lead to changes in demand and licensing strategies, which could have a material adverse effect on our business, results of operations and financial condition.

Cloud-based and SaaS computing trends present competitive and execution risks

Customers are transitioning to a hybrid computing environment utilizing various cloud-based software and services accessed via various smart client devices. Pricing and delivery models are evolving and our competitors are developing and deploying cloud-based services for customers. In addition, new cloud infrastructures are enabling the emergence of new competitors including large cloud providers who offer their own application security and delivery functionality as well as smaller companies targeting the growing numbers of "born in the cloud" applications. We are devoting significant resources to develop and deploy our own competing cloud-based and SaaS software and services strategies. While we believe our expertise and investments in software and infrastructure for cloud-based services provides us with a strong foundation to compete, it is uncertain whether our strategies will attract the customers or generate the revenue required to be successful. In addition to software development costs, we are incurring costs to build and maintain infrastructure to support cloud-computing and SaaS services, and the securitization of our customers’ data. These costs may reduce the gross and operating margins we have previously achieved. Whether we are successful in this new business model depends on our execution in a number of areas, including:

• continuing to innovate and bring to market compelling cloud-based and SaaS services through consumption models that generate increasing traffic and market share;

• maintaining the utility, compatibility and performance of our software on the growing array of cloud and SaaS computing platforms and the enhanced interoperability requirements associated with orchestration of cloud computing environments; and

• implementing the infrastructure and the securitization of our customers' data to deliver our own cloud-based and SaaS services.

These new business models may reduce our revenues or gross and operating margins and could have a material adverse effect on our business, results of operations and financial condition.

Industry consolidation may result in increased competition

Some of our competitors have made acquisitions or entered into partnerships or other strategic relationships to offer a more comprehensive solution than they had previously offered. We have also entered into large, strategic partnerships to enhance our competitive position in the marketplace. As IT companies attempt to strengthen or maintain their market positions in the evolving application delivery, mobility, cloud networking and cloud platform markets, these companies continue to seek to deliver comprehensive IT solutions to end users and combine enterprise-level hardware and software solutions that may compete with our solutions and which could negatively impact our partnerships. These consolidators or potential consolidators may have significantly greater financial, technical and other resources than we do and may be better positioned to acquire and offer complementary products and services. The companies resulting from these possible combinations may create more compelling product and service offerings and be able to offer greater pricing flexibility or sales and marketing support for such offerings than we can. These heightened competitive pressures could result in a loss of customers or a reduction in our revenues or revenue growth rates, all of which could adversely affect our business, results of operations and financial condition.

We may not be able to compete effectively in the emerging application delivery and security market

The markets we serve are new, rapidly evolving and highly competitive, and we expect competition to persist and intensify in the future. As we expand our reach and role into a broader set of multi-cloud solutions, the companies that we consider competitors evolves as well. In addition to server load balancing, traffic management, and other functions normally associated with application delivery, our suite of solutions has expanded our addressable market into security, and policy management, where we compete with a number of companies focused on niche areas of application security.

We expect to continue to face additional competition as new participants enter our markets. As we continue to expand globally, we may see new competitors in different geographic regions. In addition, larger companies with significant resources, brand recognition, and sales channels may form alliances with or acquire competing application services solutions from other companies and emerge as significant competitors. Potential competitors may bundle their products or incorporate an Internet traffic management or security component into existing products in a manner that discourages users from purchasing our products. Any of these circumstances may limit our opportunities for growth and negatively impact our financial performance.

We lease our principal administrative, sales, marketing, research and development facilities, which are located in Seattle, Washington and consist of approximately 515,000 square feet. In May 2017, we entered into a lease agreement for the building in Seattle, Washington that now serves as our corporate headquarters. This lease will expire in 2033 with an option for renewal.

We believe that our existing properties are in good condition and suitable for the conduct of our business. We also lease additional office space for product development and sales and support personnel in the United States and internationally. We believe that our future growth can be accommodated by our current facilities or by leasing additional space if necessary.

Market Prices of Common Stock

Our common stock is traded on the Nasdaq Global Select 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 Global Select Market.

The last reported sales price of our common stock on the Nasdaq Global Select Market on November 7, 2022 was $137.22.

As of November 7, 2022, there were 41 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 shareholders, we are unable to estimate the total number of beneficial holders of our common stock represented by these record holders.

Dividend Policy

Our policy has been to retain cash for use in our business, for investment in acquisitions and to repurchase shares of our common stock. Accordingly, we have not paid dividends and do not anticipate declaring dividends on our common stock in the foreseeable future.

Unregistered Securities Sold in 2022

We did not sell any unregistered shares of our common stock during the fiscal year 2022.

Issuer Purchases of Equity Securities

On July 25, 2022, we announced that our Board of Directors authorized an additional $1.0 billion for our common stock share repurchase program. This authorization is incremental to the existing $5.4 billion program, initially approved in October 2010 and expanded in subsequent fiscal years. Acquisitions for the share repurchase programs will be made from time to time in private transactions, accelerated share repurchase programs, or open market purchases as permitted by securities laws and other legal requirements. The programs can be terminated at any time.

On February 3, 2021, the Company entered into Accelerated Share Repurchase (ASR) agreements with two financial institutions under which the Company paid an aggregate of $500 million. The ASR agreements were accounted for as two separate transactions (1) a repurchase of common stock and (2) an equity-linked contract on the Company's own stock. Upon execution of the ASR agreements, the Company received an initial delivery of 2.1 million shares for an aggregate price of $400 million, based on the market price of $194.91 per share of the Company's common stock on the date of the transaction. The initial shares received by the Company were retired immediately upon receipt. The equity-linked contract for the remaining $100 million, representing remaining shares to be delivered by the financial institutions under the ASR agreements, was recorded to common stock as of March 31, 2021 and was settled in the third quarter of fiscal 2021 with the Company receiving 449,049 additional shares, which were retired immediately upon receipt. The total ASR resulted in a repurchase of 2.5 million shares of the Company's common stock at a volume weighted average repurchase price, less an agreed upon discount, of $199.90 per share. The shares received by the Company were retired, accounted for as a reduction to stockholder’s equity in the consolidated balance sheets, and treated as a repurchase of common stock for purposes of calculating earnings per share. The Company was not required to make any additional cash payments or delivery of common stock to the financial institutions upon settlement of the agreements.

During fiscal year 2022, we repurchased and retired 2,611,462 shares of common stock at an average price of $191.47 per share and as of September 30, 2022, we had $1.3 billion remaining authorized to purchase shares.

Overview

F5 is a leading provider of multi-cloud application security and delivery solutions which enable our customers to develop, deploy, operate, secure, and govern applications in any architecture, from on-premises to the public cloud. Our enterprise-grade application services are available as cloud-based, software-as-a-service, and software-only solutions optimized for multi-cloud environments, with modules that can run independently, or as part of an integrated solution on our high-performance appliances. We market and sell our products primarily through multiple indirect sales channels in the Americas; Europe, the Middle East, and Africa ("EMEA"); and the Asia Pacific region ("APAC"). Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in the technology, telecommunications, financial services, transportation, education, manufacturing, and health care industries, along with government customers, continue to make up the largest percentage of our customer base.

Our management team monitors and analyzes a number of key performance indicators in order to manage our business and evaluate our financial and operating performance on a consolidated basis. Those indicators include:

• Revenues. The majority of our product revenues are derived from sales of our application security and delivery solutions including our BIG-IP software and systems, F5 NGINX software, and our Silverline offerings. Our BIG-IP software solutions are sold both on a perpetual license and a subscription basis. We sell F5 NGINX on a subscription basis. Our Silverline solution is a managed services offering, also sold on a subscription basis. During our fiscal year 2022, we launched F5 Distributed Cloud Services. F5 Distributed Cloud Services provides security, multi-cloud networking, and edge-based computing solutions, encompassing software solutions from what were previously branded as our Shape, Volterra, and Silverline product offerings. F5 Distributed Cloud Services are offered on a subscription basis, under a unified software-as-a-service ("SaaS") platform. We also derive revenues from the sales of global services including annual maintenance contracts, training and consulting services.

We monitor the sales mix of our revenues within each reporting period. We believe customer acceptance rates of our new products, feature enhancements and consumption models are indicators of future trends. We also consider overall revenue concentration by geographic region as an additional indicator of current and future trends. Near term, we expect challenging global supply chain conditions, particularly semiconductor constraints, will result in a shortfall in our ability to meet customer demand for our hardware-based solutions, thereby impacting revenues from systems sales.

• Cost of revenues and gross margins. We strive to control our cost of revenues and thereby maintain our gross margins. Significant items impacting cost of revenues are hardware costs paid to our contract manufacturers, third-party software license fees, software-as-a-service infrastructure costs, amortization of developed technology and personnel and overhead expenses. In addition, factors such as sales price, product and services mix, inventory obsolescence, returns, component price increases, warranty costs, global supply chain constraints, and the remaining uncertainty surrounding the COVID-19 pandemic could significantly impact our gross margins from quarter to quarter.

• Operating expenses. Operating expenses are substantially driven by personnel and related overhead expenses. Existing headcount and future hiring plans are the predominant factors in analyzing and forecasting future operating expense trends. Other significant operating expenses that we monitor include marketing and promotions, travel, professional fees, computer costs related to the development of new products and provision of services, facilities and depreciation expenses.

• Liquidity and cash flows. Our financial condition remains strong with significant cash and investments. The decrease in cash and investments for fiscal year 2022 was primarily due to $500.0 million of cash used for the repurchase of shares and $68.0 million in cash paid for the acquisition of Threat Stack in the first quarter of fiscal 2022. The decrease in cash and investments for fiscal year 2022 was partially offset by cash provided by operating activities of $442.6 million. Going forward, we believe the primary driver of cash flows will be net income from operations. We will continue to evaluate possible acquisitions of, or investments in businesses, products, or technologies that we believe are strategic, which may

require the use of cash. Additionally, on January 31, 2020, we entered into a Revolving Credit Agreement (the "Revolving Credit Agreement") that provides for a senior unsecured revolving credit facility in an aggregate principal amount of $350.0 million (the "Revolving Credit Facility"). We have the option to increase commitments under the Revolving Credit Facility from time to time, subject to certain conditions, by up to $150.0 million. As of September 30, 2022, there were no outstanding borrowings under the Revolving Credit Facility, and we had available borrowing capacity of $350.0 million.

• Balance sheet. We view cash, short-term and long-term investments, deferred revenue, accounts receivable balances and days sales outstanding as important indicators of our financial health. Deferred revenues continued to increase in fiscal 2022 due to the growth of our subscriptions business. Our days sales outstanding for the fourth quarter of fiscal year 2022 was 60. Days sales outstanding is calculated by dividing ending accounts receivable by revenue per day for a given quarter.

Critical Accounting Policies and Estimates

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 that, of our significant accounting policies, which are described in Note 1 of the notes to the consolidated financial statements, the following accounting policies involve a greater degree of judgment and complexity. Accordingly, these are the policies we believe are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations.

Revenue Recognition. We sell products through distributors, resellers, and directly to end users. Revenue related to our contracts with customers is recognized by following a five-step process:

• Identify the contract(s) with a customer. Evidence of a contract generally consists of a purchase order issued pursuant to the terms and conditions of a distributor, reseller or end user agreement.

• Identify the performance obligations in the contract. Performance obligations are identified in our contracts and include hardware, hardware-based software, software-only solutions, cloud-based subscription services as well as a broad range of service performance obligations including consulting, training, installation and maintenance.

• Determine the transaction price. The purchase price stated in an agreed upon purchase order is generally representative of the transaction price. We offer several programs in which customers are eligible for certain levels of rebates if certain conditions are met. When determining the transaction price, we consider the effects of any variable consideration.

• Allocate the transaction price to the performance obligations in the contract. The transaction price in a contract is allocated based upon the relative standalone selling price of each distinct performance obligation identified in the contract.

• Recognize revenue when (or as) the entity satisfies a performance obligation. We satisfy performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring control of promised products and services to a customer.

Revenue is recognized net of any taxes collected, which are subsequently remitted to governmental authorities. Shipping and handling fees charged to our customers are recognized as product revenue in the period shipped and the related costs for providing these services are recorded as a cost of sale.

The following is a description of the principal activities from which we generate revenue:

Product

Revenue from the sale of our hardware and perpetual software products is generally recognized at a point in time when the product has been fulfilled and the customer is obligated to pay for the product. We also offer several products by subscription, either through term-based license agreements or as SaaS offerings. Revenue for term-based license agreements is recognized at a point in time when we deliver the software license to the customer and the subscription term has commenced. For our SaaS offerings, revenue is recognized ratably as the services are provided. Hardware, including the software run on those devices is considered systems revenue. Perpetual or subscription software offerings that are deployed on a standalone basis, along with our SaaS offerings, are considered software revenue. When rights of return are present and we cannot estimate returns, revenue is recognized when such rights of return lapse. Payment terms to customers are generally net 30 days to net 60 days.

Table of Contents

Global Services

Revenues for post-contract customer support (PCS) are recognized on a straight-line basis over the service contract term. PCS includes a limited period of telephone support, updates, repair or replacement of any failed product or component that fails during the term of the agreement, bug fixes and rights to upgrades, when and if available. Consulting services are customarily billed at fixed hourly rates, plus out-of-pocket expenses, and revenues are recognized as the consulting is completed. Similarly, training revenue is recognized as the training is completed.

Contract Acquisition Costs

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for initial service contracts and subscription offerings are deferred and then amortized as an expense on a straight-line basis over the period of benefit which management has determined to be 4.5 years and 3 years, respectively.

Significant Judgments

We enter into certain contracts with customers, including flexible consumption programs and multi-year subscriptions, with non-standard terms and conditions. Management exercises significant judgment in assessing contractual terms in these arrangements to identify and evaluate performance obligations. Management allocates consideration to each performance obligation based on relative fair value using standalone selling price and recognizes associated revenue as control is transferred to the customer.

Business Combinations. Our business combinations are accounted for under the acquisition method. We allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets.

COVID-19 Update

Management has prioritized a human-first approach to the COVID-19 pandemic. For F5, this means ensuring the health and safety of employees, their families and our communities. Further, this approach extends to our customers as we look for ways that we can support their operations.

We continue to monitor the ongoing uncertainty related to the global pandemic on our business and financial outlook. Global supply chain constraints in the wake of the COVID-19 pandemic have reduced our visibility into component availability and lead times and costs have increased for components necessary for our hardware-based solutions. We are continuing to undertake efforts to mitigate supply chain constraints, but pandemic-related impacts to component availability have lengthened systems shipment lead times and delayed our ability to fulfill some hardware orders. In addition, we are conducting business with modifications to employee travel, employee work locations, and virtualization of certain sales and marketing events, among other modifications. We will continue to actively monitor the situation and may take further actions that alter our business operations as may be required by federal, state or local authorities, or that we determine are in the best interests of our employees, customers, partners, suppliers and stockholders. It is not clear what the potential effects any such alterations or modifications may have on our business, including the effects on our customers and prospects, or on our financial results.

Results of Operations

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.

Table of Contents

Net Revenues. Total net revenues increased 3.6% in fiscal year 2022 from fiscal year 2021, compared to an increase of 10.7% in fiscal year 2021 from the prior year. Overall revenue growth for the year ended September 30, 2022 was due to increases in both product and service revenue. The product revenue increase was driven by software revenue increases, specifically from our subscription-based offerings, which include software sold via our flexible consumption program or multi-year subscriptions, and our SaaS product offerings. This was partially offset by a decrease in systems revenue associated with a shortage of components required to meet systems demand. Service revenues increased as a result of our increased installed base of products. International revenues represented 44.8%, 47.5% and 48.1% of net revenues in fiscal years 2022, 2021 and 2020, respectively.

Net Product Revenues. Net product revenues increased 5.6% in fiscal year 2022 from fiscal year 2021, compared to an increase of 21.6% in fiscal year 2021 from the prior year. The increase of $70.0 million in net product sales for fiscal year 2022 was due to continued growth in software revenue, partially offset by a decrease in systems revenue associated with a shortage of components to meet systems demand. The increase of $221.2 million in net product sales for fiscal year 2021 was primarily due to an increase in both software and systems revenue compared to the prior year.

The following presents net product revenues by systems and software (in thousands):

Net Service Revenues. Net service revenues increased 1.7% in fiscal year 2022 from fiscal year 2021, compared to an increase of 2.4% in fiscal year 2021 from the prior year. The increases in service revenue were the result of increased purchases or renewals of maintenance contracts driven by additions to our installed base of products.

The following distributors of our products accounted for more than 10% of total net revenue:

Table of Contents

The following distributors of our products accounted for more than 10% of total receivables:

No other distributors accounted for more than 10% of total net revenue or receivables.

Cost of Net Product Revenues. Cost of net product revenues consist of finished products purchased from our contract manufacturers, manufacturing overhead, freight, warranty, provisions for excess and obsolete inventory, software-as-a-service infrastructure costs and amortization expenses in connection with developed technology from acquisitions. Cost of net product revenues increased to $319.7 million in fiscal year 2022, up 11.7% from the prior year, primarily due to software product revenue growth. In addition, we experienced an increase in component prices, expedite fees and other sourcing-related costs in fiscal 2022. Cost of net product revenues increased to $286.3 million in fiscal year 2021, up 33.0% from the prior year, primarily due to software product revenue growth.

Cost of Net Service Revenues. Cost of net service revenues consist of the salaries and related benefits of our professional services staff, travel, facilities and depreciation expenses. Cost of net service revenues as a percentage of net service revenues increased to 16.0% in fiscal year 2022 compared to 15.3% in fiscal year 2021 and 14.5% in fiscal year 2020. Professional services headcount at the end of fiscal 2022 increased to 1,091 from 1,014 at the end of fiscal 2021. Professional services headcount at the end of fiscal year 2021 increased to 1,014 from 965 at the end of fiscal 2020. In addition, cost of net service revenues included stock-based compensation expense of $21.9 million, $22.1 million and $20.8 million for fiscal years 2022, 2021 and 2020, respectively.

Sales and Marketing. Sales and marketing expenses consist 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, travel, facilities, and depreciation expenses. Sales and marketing expense remained relatively flat in fiscal year 2022 from the prior year, as compared to a year-over-year increase of 10.3% in fiscal year 2021. Sales and marketing expense for fiscal year 2022 included a decrease of $14.0 million in commissions, partially offset by an increase in employee travel and customer outreach of $12.9 million, compared to the prior year. Sales and marketing headcount at the end of fiscal year 2022 increased to 2,500 from 2,479 at the end of fiscal year 2021. In fiscal year 2021, the increase in sales and marketing expense was primarily due to increases in commissions and personnel costs of $57.3 million, compared to the prior year. The increases in commissions and personnel costs were driven by growth in sales and marketing employee headcount during fiscal year 2021, including employees from the acquisition of Volterra, as well as higher commissions related to software sales. Sales and marketing headcount at the end of fiscal year 2021 increased to 2,479 from 2,395 at the end of fiscal year 2020. Sales and marketing expenses for fiscal year 2021 also included impairment charges of $11.5 million related to the exit of certain facilities. Sales and marketing expense included stock-based compensation expense of $104.3 million, $104.6 million and $88.4 million for fiscal years 2022, 2021 and 2020, respectively.

Research and development expenses consist of the salaries and related benefits of our product development personnel, prototype materials and other expenses related to the development of new and improved products, facilities and depreciation expenses. Research and development expense increased 6.0% in fiscal year 2022 from the prior year, as compared to a year-over-year increase of 16.2% in fiscal year 2021. The increase in research and development expense for fiscal year 2022 was primarily due to increased personnel costs of $29.6 million, compared to the prior year. The increase in personnel costs were driven by growth in research and development employee headcount during fiscal year 2022, including employees from the acquisition of Threat Stack. Research and development headcount at the end of fiscal year 2022 increased to 2,170 from 1,884 at the end of fiscal year 2021. In fiscal year 2021, the increase in research and development expense was primarily due to increased personnel costs of $48.8 million, compared to the prior year. The increase in personnel costs were driven by growth in research and development employee headcount during fiscal year 2021, including employees from the acquisition of Volterra. Research and development headcount at the end of fiscal year 2021 increased to 1,884 from 1,797 at the end of fiscal year 2020. Research and development expenses for fiscal year 2021 also included impairment charges of $13.0 million related to the exit of certain facilities. Research and development expense included stock-based compensation expense of $71.8 million, $67.2 million and $50.3 million for fiscal years 2022, 2021 and 2020, respectively.

General and Administrative. General and administrative expenses consist 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, facilities and depreciation expenses. General and administrative expense remained relatively flat in fiscal year 2022 from the prior year, as compared to a year-over-year increase of 5.9% in fiscal year 2021. General and administrative expense for fiscal year 2022 included an increase of $15.4 million in personnel costs, partially offset by a decrease in fees paid to outside consultants for legal, accounting and tax services of $7.0 million and a decrease in facilities costs of $7.7 million, compared to the prior year. The increase in personnel costs were driven by growth in general and administrative employee headcount during fiscal year 2022. General and administrative headcount at the end of fiscal year 2022 increased to 984 from 829 at the end of fiscal year 2021. In fiscal year 2021, the increase in general and administrative expense was primarily due to increased personnel costs of $11.7 million, compared to the prior year. The increase in personnel costs were driven by growth in general and administrative employee headcount during fiscal year 2021, including employees from the acquisition of

Table of Contents

Volterra. General and administrative headcount at the end of fiscal year 2021 increased to 829 from 704 at the end of fiscal year 2020. General and administrative expenses for fiscal year 2021 also included impairment charges of $9.9 million related to the exit of certain facilities. General and administrative expense included stock-based compensation expense of $43.9 million, $42.4 million and $37.8 million for fiscal years 2022, 2021 and 2020, respectively.

Restructuring charges. In the first fiscal quarters of 2022 and 2020, we completed restructuring programs to align strategic and financial objectives and optimize resources for long-term growth. As a result of these initiatives, we recorded restructuring charges of $7.9 million and $7.8 million related to a reduction in workforce that is reflected in our results for the years ended September 30, 2022 and 2020, respectively. There were no restructuring expenses recorded for the year ended September 30, 2021.

Other (Expense) Income, Net. Other (expense) income, net, consists primarily of interest income and expense and foreign currency transaction gains and losses. Other (expense) income, net decreased $11.3 million in fiscal year 2022, as compared to fiscal year 2021 and decreased $11.2 million in fiscal year 2021, as compared to fiscal year 2020. The decrease in other (expense) income, net for fiscal year 2022 was primarily due to an increase in foreign currency loss of $7.8 million, and an increase in interest expense of $2.7 million, compared to the prior year. The decrease in other (expense) income, net for fiscal year 2021 as compared to fiscal year 2020 was primarily due to a decrease of $9.8 million in interest income from our investments compared to the prior year, and an increase in foreign currency losses of $2.3 million, compared to the prior year.

Provision for Income Taxes. We recorded a 16.4% provision for income taxes for fiscal year 2022, compared to 14.4% in fiscal year 2021 and 22.4% in fiscal year 2020. The increase in the effective tax rate from fiscal year 2021 to 2022 is primarily due to a discrete impact recorded in fiscal year 2021 from filing the Company’s fiscal year 2020 U.S. federal income tax return. The decrease in the effective tax rate from fiscal year 2020 to 2021 is primarily due to a discrete impact from filing the Company's fiscal year 2020 U.S. federal income tax return and the tax impact from stock based compensation.

We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than not to be realized. In making these determinations we consider historical and projected taxable income, and ongoing prudent and feasible tax planning strategies in assessing the appropriateness of a valuation allowance. The net increase in the valuation allowance of $5.7 million for fiscal year 2022 and $7.8 million for fiscal year 2021 was primarily related to tax net operating losses and credits incurred in certain foreign jurisdictions and state tax carryforwards. Our net deferred tax assets as of September 30, 2022, 2021 and 2020 were $180.6 million, $125.8 million, and $44.6 million respectively.

Our worldwide effective tax rate may fluctuate based on a number of factors, including variations in projected taxable income in the various geographic locations in which we operate, changes in the valuation of our net deferred tax assets, resolution of potential exposures, tax positions taken on tax returns filed in the various geographic locations in which we operate, and the introduction of new accounting standards or changes in tax laws or interpretations thereof in the various geographic locations in which we operate. We have recorded liabilities to address potential tax exposures related to business and income tax positions we have taken that could be challenged by taxing authorities. The ultimate resolution of these potential exposures may be greater or less than the liabilities recorded which could result in an adjustment to our future tax expense.

Liquidity and Capital Resources

We have funded our operations with our cash balances and cash generated from operations.

Cash and cash equivalents, short-term investments and long-term investments totaled $894.1 million as of September 30, 2022, compared to $1,043.4 million as of September 30, 2021, representing a decrease of $149.3 million. The decrease was primarily due to $500.0 million of cash required for the repurchase of outstanding common stock and $68.0 million in cash paid for the acquisition of Threat Stack in the first quarter of fiscal 2022. The decrease was also driven by $33.6 million of capital expenditures related to the expansion of our facilities to support our operations worldwide as well as investments in information technology infrastructure and equipment purchases to support our core business activities. The decrease was partially offset by cash provided by operating activities of $442.6 million. As of September 30, 2022, 62.8% of our cash and cash equivalents and investment balances were outside of the U.S. The cash and cash equivalents and investment balances outside of the U.S. are subject to fluctuation based on the settlement of intercompany balances. In fiscal year 2021, the decrease to cash and cash equivalents, short-term investments and long-term investments from the prior year was primarily due to $500.0 million of cash required for the repurchase of outstanding common stock under our Accelerated Share Repurchase agreements and $411.3 million in cash paid for the acquisition of businesses, primarily Volterra in the second quarter of fiscal 2021. The decrease was also driven by $30.7 million of capital expenditures related to the expansion of our facilities to support our operations worldwide as well as investments in information technology infrastructure and equipment purchases to support our core business activities. The decrease was partially offset by cash provided by operating activities of $645.2 million. As of September 30, 2021, 54.9% of our cash and cash equivalents and investment balances were outside of the U.S.

Cash provided by operating activities during fiscal year 2022 was $442.6 million compared to $645.2 million in fiscal year 2021 and $660.9 million in fiscal year 2020. Cash provided by operating activities resulted primarily from cash generated from net income, after adjusting for non-cash charges such as stock-based compensation, depreciation and amortization charges and changes in operating assets and liabilities. Cash provided by operating activities for fiscal year 2022 decreased from the prior year primarily due to strong multi-year subscription sales in fiscal year 2022, which are generally sold on three-year terms. Multi-year subscriptions are billed on an annual basis with the remainder recognized on the balance sheet as unbilled assets. In addition, during fiscal year 2022, we had significant prepayments with our contract manufacturer associated with components for future hardware-based solution builds.

Cash from operations could be affected by various risks and uncertainties, including, but not limited to the risks detailed in Part I, Item 1A titled “Risk Factors.” However, we anticipate our current cash, cash equivalents and investment balances, anticipated cash flows generated from operations, and available borrowing capacity on the Revolver Credit Facility will be sufficient to meet our liquidity needs.

Cash provided by investing activities during fiscal year 2022 was $218.1 million compared to cash used in investing activities of $445.3 million in fiscal year 2021 and $747.0 million in fiscal year 2020. Investing activities include purchases, sales and maturities of available-for-sale securities, business acquisitions and capital expenditures. Cash provided by investing activities for fiscal year 2022 was primarily the result of $260.4 million in maturities of investments and $120.6 million in sales of investments, partially offset by $68.0 million cash paid for the acquisition Threat Stack in the first quarter of fiscal 2022 and purchases of investments of $61.3 million. Cash used in investing activities for fiscal year 2021 was primarily the result of $411.3 million in cash paid for the acquisition businesses, primarily Volterra in the second quarter of fiscal 2021, along with capital expenditures related to maintaining our operations worldwide and the purchase of investments, partially offset by the maturity and sale of investments. Cash used in investing activities for fiscal year 2020 was primarily the result of $955.6 million in cash paid for the acquisition of Shape, along with capital expenditures related to maintaining our operations worldwide and the purchase of investments, partially offset by the maturity and sale of investments.

Cash used in financing activities was $476.5 million for fiscal year 2022, compared to cash used in financing activities of $468.3 million for fiscal year 2021 and cash provided by financing activities of $337.2 million for fiscal year 2020. Cash used in financing activities for fiscal year 2022 included $500.0 million to repurchase shares under our Share Repurchase program,

as well as $21.0 million in cash used for taxes related to net share settlement of equity awards and $20.0 million in cash used to make principal payments on our term loan. Cash used in financing activities was partially offset by cash received from the exercise of employee stock options and stock purchases under our employee stock purchase plan of $64.5 million. Cash used in financing activities for fiscal year 2021 included $500.0 million to repurchase shares under our Accelerated Share Repurchase agreements, as well as $20.0 million in cash used to make principal payments on our term loan and $14.0 million in cash used for taxes related to net share settlement of equity awards. Cash used in financing activities was partially offset by cash received from the exercise of employee stock options and stock purchases under our employee stock purchase plan of $65.8 million. Cash provided by financing activities for fiscal year 2020 included $400.0 million in cash proceeds from a term loan, as well as cash received from the exercise of employee stock options and stock purchases under our employee stock purchase plan of $52.8 million, partially offset by $100.0 million in cash used to repurchase common stock under our share repurchase program and $10.0 million in cash used to make a principal payment on our term loan.

On January 31, 2020, we entered into a Revolving Credit Agreement (the "Revolving Credit Agreement") that provides for a senior unsecured revolving credit facility in an aggregate principal amount of $350.0 million (the "Revolving Credit Facility"). We have the option to increase commitments under the Revolving Credit Facility from time to time, subject to certain conditions, by up to $150.0 million. As of September 30, 2022, there were no outstanding borrowings under the Revolving Credit Facility, and we had available borrowing capacity of $350.0 million.

Based on our current operating and capital expenditure forecasts, we believe that our existing cash and investment balances, together with cash generated from operations should be sufficient to meet our operating requirements for the next twelve months. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, the timing and extent of expansion into new territories, the timing of introductions of new products and enhancements of existing products, the continuing market acceptance of our products and cash paid for future acquisitions.

Obligations and Commitments

As of September 30, 2022, we had approximately $69.7 million of tax liabilities, including interest and penalties, related to uncertain tax positions (See Note 8 to our Consolidated Financial Statements). Because of the high degree of uncertainty regarding the settlement of these liabilities, we are unable to estimate the years in which future cash outflows may occur.

As of September 30, 2022, our principal commitments consisted of borrowings under the Term Loan Facility and obligations outstanding under operating leases.

In connection with the acquisition of Shape, on January 24, 2020, we entered into a Term Credit Agreement ("Term Credit Agreement") with certain institutional lenders that provides for a senior unsecured term loan facility in an aggregate principal amount of $400.0 million (the "Term Loan Facility"). The proceeds from the Term Loan Facility were primarily used to finance the acquisition of Shape and related expenses. As of September 30, 2022, $350.0 million of principal amount under the Term Loan Facility was outstanding. There is a financial covenant that requires us to maintain a leverage ratio, calculated as of the last day of each fiscal quarter, of consolidated total indebtedness to consolidated EBITDA. This covenant may result in a higher interest rate on our outstanding principal borrowings on the Term Loan Facility in future periods, depending on the Company's performance. Refer to Note 6 of our Consolidated Financial Statements for the scheduled principal maturities of the Term Loan Facility as of September 30, 2022.

We have a contractual obligation to purchase inventory components procured by our primary contract manufacturer in accordance with our annual build forecast. The contractual terms of the obligation contain cancellation provisions, which reduce our liability to purchase inventory components for periods greater than one year. In order to support our build forecast, we will, from time-to-time prepay our primary contract manufacturer for inventory purchases.

Recently Adopted Accounting Standards

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. The Company early adopted this accounting standard update beginning in the first quarter of fiscal 2022 and it did not have a material impact on the Company's consolidated financial statements.

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 5% of the total portfolio with the exception of U.S. treasury and agency securities and money market funds, which are exempt from size limitation. The policy requires investments in securities that mature in three years or less, with the average maturity being no greater than one and a half years. These securities are subject to interest rate risk and will decrease in value if interest rates increase. A hypothetical increase in interest rates of 100 basis points at September 30, 2022 could result in a market value reduction for our portfolio of approximately $0.5 million.

Inflation Risk. We are actively monitoring the current inflationary environment, but we do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations. If the current inflationary environment constrains our customers’ ability to procure goods and services from us, we may see customers reprioritize these investment decisions. These macroeconomic conditions could harm our business, financial condition and results of operations.

Foreign Currency Risk. The majority of our sales, cost of net revenues, and operating 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 conduct transactions in foreign currencies 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, transaction gains or losses may become significant in the future.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of F5, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of F5, Inc. and its subsidiaries (the “Company”) as of September 30,2022 and 2021, and the related consolidated statements of income, of comprehensive income, of shareholders’ equity and of cash flows for each of the three years in the period ended September 30, 2022, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of September 30, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 30, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Changes in Accounting Principles

As discussed in Note 7 to the consolidated financial statements, the Company changed the way the manner in which it accounts for leases as of October 1, 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

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

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

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that required information is recorded, processed, summarized and reported within the required timeframe, as specified in the rules set forth by the Securities Exchange Commission. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures.

Table of Contents

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2022 and, based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of September 30, 2022.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management conducted an assessment of the effectiveness of our internal control over financial reporting as of September 30, 2022. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated Framework (2013). Based on the results of this assessment and on those criteria, management concluded that our internal control over financial reporting was effective as of September 30, 2022.

The effectiveness of the Company’s internal control over financial reporting as of September 30, 2022, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control over Financial Reporting

During the fourth fiscal quarter, there were no changes to our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
