F5 Networks, Inc.

Conflict Minerals Report

Year Ended December 31, 2020

Introduction

This Conflict Minerals Report (the "Report") for F5 Networks, Inc. ("F5 Networks," "F5," the "Company," "we," "us," and "our") is presented for the reporting period from January 1, 2020 to December 31, 2020 to comply with Rule 13p-1 (the "Rule") under the Securities Exchange Act of 1934. For the purpose of the Reasonable Country of Origin Inquiry ("RCOI"), we initiated supply chain inquiries in December 2020 and continued to receive data through May 03, 2021. F5 maintains an ongoing data gathering and refresh program to ensure up-to-date data is captured throughout the year. For the purpose of this report, conflict minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, tungsten, and gold (collectively, "3TG").

This year, we received responses from 93% of our in-scope suppliers. After validation and removal of incomplete or invalid submissions, we received an acceptable, completed Conflict Minerals Reporting Template ("CMRT") from 90% of our in-scope suppliers, and were able to determine 13% of suppliers were not using any 3TG. 4% of the suppliers provided incomplete or invalid submissions.

As a downstream user of conflict minerals, we are dependent on our suppliers for information, and the list of smelters reported by F5 should be seen as a list of possible sources, rather than a complete record of known source locations. More information on how we determined which suppliers were in scope is available in this report.

A smelter list, CMRT form, conflict minerals policy, and other corporate social responsibility information is available online at https://support.f5.com/csp/article/K51230228.

Our customers include large enterprise businesses, public sector institutions, governments, and service providers around the globe.

Supply Chain Overview

F5 relies upon our suppliers to provide material declarations and information on the origin of 3TG contained in components and materials supplied to us, including materials and 3TG from sub-tier suppliers. As most suppliers provide company-level declarations, there are many smelters listed that may not actually be in the supply chain of the components used by F5.

We contracted with Assent Compliance ("Assent") to gather data from our suppliers as well as to provide our suppliers training on the reporting rules and guidance on completing the CMRT form. We utilized the standard Responsible Business Alliance Global e-Sustainability Initiative ("RBA-GeSI") Conflict Minerals Reporting Template version 6.01 developed by the Responsible Minerals Initiative ("RMI") and requested that all suppliers complete the form. Suppliers that are known or suspected to provide components that contain 3TG were considered undetermined unless a completed CMRT form was received. Suppliers known not to use metal in products sourced by F5 Networks were asked to provide a CMRT form, even if only to state no use. In cases where these suppliers did not provide a CMRT form, but a material declaration or comparable documentation is on file demonstrating no 3TG use, they were considered out of scope. Packaging suppliers are out of scope,

and though we have asked for CMRT forms for our own records they are excluded from this declaration and the data provided herein.

Reasonable Country of Origin Inquiry

To determine whether necessary 3TG in our products originated in the Democratic Republic of the Congo ("DRC") or an adjoining country (the "Covered Countries"), we provided a list of suppliers associated with the Covered Products to Assent for upload to the Assent Compliance Manager tool ("ACM").

We utilized the RBA-GeSI CMRT version 6.01 to conduct a survey of all in scope suppliers. During the supplier survey, we contacted suppliers via the ACM, to which suppliers uploaded their completed CMRTs for assessment and management by Assent. The use of the CMRT allowed for some elimination of irrelevant suppliers. Specifically, Question 1 of the CMRT asks suppliers whether any of the 3TGs they use are necessary to the functionality or production of their products. We also periodically reviewed the supplier list to ensure that irrelevant or "out of scope" suppliers were removed from the survey process. We conducted this analysis based on the following criteria:

•The company supplies packaging only (excluding labels)

•The company supplies us with items that do not end up in our products (including equipment used to make our products or those used strictly on prototypes)

•The company is a test lab

•The company is a service provider only

•The company is listed as a supplier, but no components were purchased for use in F5 products during the reporting period and preceding 12 months.

We requested that all suppliers complete a CMRT and included training and education (provided by Assent) to guide suppliers on best practices and the use of this template. Assent monitored and tracked all communications in the ACM for future reporting and transparency. We directly contacted suppliers that were unresponsive to Assent’s communications during the diligence process and requested such suppliers to complete the CMRT form and submit their form to Assent.

For calendar year 2020 we included automated data validation on all submitted CMRTs. The goal of data validation is to increase the accuracy of submissions and identify any contradictory answers in the CMRT. This data validation is based on:

•Questions 1 and 2 are minimum requirements for the CMRT

◦If suppliers state (via Question 1 and Question 2) that their products do not contain 3TGs necessary to the function or production of said products, then no further information is required, and no further data validation is completed.

•Question 3 - Do any of your 3TGs originate from the Covered Countries?

◦Any supplier that has any 3TGs from the Covered Countries, even one positive response from their supply chain must answer yes.

•Question 4 - Do any of the smelters in your supply chain source the 3TG from conflict-affected and high-risk areas?

•Question 5 - Have you received information from all relevant 3TG Suppliers?

◦If you are not at 100%, then you cannot make definitive statements for Questions 3 and 4.

•Question 6 - What percentage of relevant suppliers have provided a response to your supply chain survey?

•Question 7 - Have you identified all your Smelters and refiners?

◦If the answer here is yes, then question 5 must be yes. This also impacts question 3.

All submitted forms are accepted and classified as valid or invalid so that data is still retained. Suppliers are contacted with regards to invalid forms and are encouraged to submit a valid form. As of May 03, 2021, there were 6 invalid or incomplete supplier submissions that could not be corrected.

Assent compared the list of smelters and refiners provided in our suppliers’ responses to the lists of smelters maintained by the RMI and, if a supplier indicated that a facility was certified as conflict-free, confirmed that the facility was listed on RMI’s list of validated conflict free smelters and refiners of 3TG. Our suppliers identified a total of 318 smelters and refiners. Of those, 236 are currently conformant to the Responsible Minerals Audit Process ("RMAP") run by RMI. Based on information provided by RMI, a further 8 are in communication with RMI. Most of the CMRTs we received were made on a company or division level basis which did not allow us to identify which smelters or refiners listed by our suppliers actually processed the 3TG contained in our products.

Based on the RCOI, we had reason to believe that some of the 3TGs may have originated from the Covered Countries. In accordance with the Rule, we performed due diligence on the source and chain of custody of the conflict minerals in question.

Design of Due Diligence

We designed our due diligence measures to conform, in all material respects, with the framework in the Organization for Economic Co-operation and Development ("OECD") Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict Affected and High-Risk Areas (the "Guidance") and the related Supplements for gold, tin, tantalum, and tungsten. The Guidance identifies five steps for due diligence that should be implemented and provides guidance as to how to achieve each step. We developed our due diligence process to address each of these five steps:

1.Establishing strong company management systems regarding conflict minerals;

2.Identifying and assessing risks in our supply chain;

3.Designing and implementing a strategy to respond to identified risks in our supply chain;

4.Utilizing independent third-party audits of supply chain diligence; and

5.Publicly reporting on our supply chain due diligence.

Company Management System

Company Policies

All suppliers in our manufacturing supply chain are required to provide products that meet the requirements laid out in F5’s Conflict Minerals Policy which can be found here: https://support.f5.com/csp/article/K51230228.

Conflict Minerals Policy (as of May 03, 2021):

As a global company, we know the business of F5 has impacts throughout our world-wide value chain. The Dodd-Frank Consumer Protection and Wall Street Reform Act (the "Dodd-Frank Act") found that the exploitation and trade of Tin, Tantalum, Tungsten, and Gold ("conflict minerals") were helping to finance extreme levels of violence in the DRC. The Dodd-Frank Act requires public companies to conduct due diligence and make certain disclosures regarding use of the conflict minerals.

F5 requires suppliers using any of the four conflict minerals sourced from the DRC or an adjoining country to use only materials which are certified Conflict Free through the Conflict Free Smelter Initiative or a comparable process.

We are committed to eliminating conflict minerals from our manufacturing supply chain through use of widely adopted best practices, including:

•Establishing a conflict minerals compliance program consistent with the OECD Due Diligence guidance for downstream companies

•Determining which F5 suppliers use the above-mentioned conflict minerals and targeting our efforts accordingly

•Requiring all affected suppliers to provide a Conflict Minerals Reporting Template to the social responsibility team for review

•When instances of non-compliant suppliers arise, working with those suppliers through our manufacturing supply chain team to ensure corrective actions are undertaken promptly and effectively

•Filing an annual Form SD with the Securities and Exchange Commission through our financial reporting group, which will include updates on progress towards being conflict free and details of any corrective actions taken in the reporting year

Developing total transparency in the supply chain takes time, and correcting suppliers’ use of non-certified conflict minerals as it arises requires commitment. We are confident our efforts, combined with the rest of the industry will result in substantive impacts for the people of the DRC and surrounding region.

Management Team

Management for the conflict minerals program at F5 is the supply chain team (within manufacturing). This team works closely with peers in manufacturing, manufacturing supply chain, and product design.

The corporate social responsibility team oversees gathering CMRTs, performing assessments of the CMRTs, following up with suppliers, filing the conflict minerals report, working with F5’s contract manufacturer to determine purchase history and supplier use, and maintaining up-to-date information on conflict minerals regulations. As discussed earlier in this report, some of those responsibilities have been outsourced to Assent.

The supply chain team (within manufacturing) is responsible for keeping up-to-date contacts with suppliers and managing contracts with suppliers with which F5 has contracts. F5 does not have contracts with all suppliers, but all contracts that are in place include conflict minerals requirements.

The product development team, particularly the team of component engineers, is responsible for maintaining up-to-date supplier lists and bills of materials. When a new supplier is added, they notify the corporate social responsibility team so due diligence can commence. When a supplier must be removed due to conflict minerals use, the corporate social responsibility team engages the component engineering and product development teams to develop and implement a phase-out plan including timeline and alternate supplier qualification.

Supplier Engagement

Design Process

F5 selects suppliers for a variety of performance criteria, including compliance. Initial screening of suppliers covers basic compliance criteria, including an ability to provide a CMRT to F5 though that CMRT is not reviewed as part of the new supplier process.

After selection, parts are integrated into prototype bills of materials and then integrated into regular, ongoing data collection performed by the corporate social responsibility team. This includes conflict minerals compliance and full material declarations.

Incorporation into Production Bill of Materials

Once listed on a prototype or production bill of materials, a supplier is added to our surveys of compliance information. It is at this point Assent is engaged to procure a CMRT from the supplier. Assent utilizes contact information provided by F5 as well as contacts from other downstream users to initiate contact with a supplier. In the event a supplier is unfamiliar with conflict minerals reporting, Assent provides training on how to properly fill out a CMRT and guidance on how that supplier can perform their own supply chain due diligence.

Maintenance of Data

After completion, F5 holds CMRTs in the ACM. These documents will be held, at a minimum, for the required period as dictated by the SEC.

As long as a supplier remains on a bill of materials for a product still in production and with an active purchase history within the prior two years, F5 will continue to gather a new CMRT every year. This ensures changes in suppliers’ practices have not resulted in a change in conflict mineral sourcing status.

Due Diligence for Calendar Year 2020

Risk Assessment

Of the suppliers deemed in scope, we found the majority to be responsive with continually improving data and coverage year over year.

Once received, a CMRT is reviewed for a variety of red flags including those listed in the OECD guidance for downstream companies. This includes, but is not limited to:

•Determining the legitimacy of all smelters listed through a variety of validated smelter lists such as those maintained by the RMI.

•Maintaining an up-to-date list of certified conflict-free smelters and checking reported smelters against that list.

•Determining if a smelter, even if outside the Covered Countries, lists source material from the Covered Countries.

•Flagging smelters and suppliers listing recycled, scrap, or bank sources of materials.

•Flagging smelters and suppliers with unfixed inconsistencies in their forms.

Assent provides potential corrective action guidance to suppliers with data inconsistencies and errors; the average CMRT has been reviewed three times by Assent and the providing supplier prior to receipt of that CMRT by F5. F5 monitors this process through updates from Assent and advises on action for suppliers whose data has not met Assent’s basic threshold for trustworthiness.

Supplier Risk

Suppliers that have not improved the percent of their supply chain surveyed, provided data showing they are not conflict free, or provided metals from other sanctioned countries were considered high-risk.

High-risk suppliers have been contacted throughout calendar year 2020 so F5 can monitor progress on removing smelters not shown to be conflict free or sourcing material from sanctioned countries.

As per the OECD Due Diligence Guidance, risk mitigation will depend on the supplier’s specific context. Suppliers are given clear performance objectives within reasonable timeframes with the goal of progressive elimination of these risks from the supply chain.

Additionally, suppliers are evaluated on program strength (further assisting in identifying risk in the supply chain). Evaluating and tracking the strength of the program meets the OECD Due Diligence Guidelines and can assist in making key risk mitigation decisions as the program progresses. At this time, 6 of our suppliers have been identified as having a weak program.

Smelter Risk

Furthermore, smelters or refiners not being certified DRC Conflict Free pose a significant risk to the supply chain. Each facility that meets the RMI definition of a smelter or refiner of a 3TG mineral is assigned a risk of high, medium or low based on 3 scoring criteria:

•Geographic proximity to the DRC and Covered Countries;

•Responsible Minerals Assurance Process (RMAP) audit status; and

•Known or plausible evidence of unethical or conflict sourcing.

Based on these criteria, the following facilities have been identified with a red-flag risks of highest concern into their supply chain:

•African Gold Refinery - CID003185

•Fidelity Printers and Refiners Ltd. - CID002515

•Sudan Gold Refinery - CID002567

•Tony Goetz NV - CID002587

•Kaloti Precious Metals - CID002563

When these facilities were reported on a CMRT by one of the suppliers surveyed, risk mitigation activities were initiated. Through our third-party vendor, Assent Compliance, submissions that include any facilities with the above conditions immediately produce a receipt instructing the supplier to take their own risk mitigation actions, including submission of a product specific CMRT to better identify the connection to products that they supply to F5, and escalating up to removal of these high-risk smelters from their supply chain.

Strategy to Respond to Risks

Together with Assent, we developed processes to assess and respond to the risks identified in our supply chain.

Non-Responsive Suppliers

As the conflict minerals due diligence progresses, escalations are sent to non-responsive suppliers to outline the importance of a response via CMRTs and to outline the required cooperation for compliance to the Conflict Minerals rules. Assent provides training on conflict minerals and filling out a CMRT.

Various reasons have been presented for why a supplier does not respond, but the most frequent is out of date contact information. In this case, F5's social responsibility team and supply chain team gather up-to-date supplier contact information. F5’s contract manufacturer, Flex, may be asked to provide their contact with suppliers. Working with Flex also helps eliminate some confusion with suppliers requiring purchase orders to provide information; Flex is typically the purchaser of record, even though F5 maintains design control.

Suppliers with Persistent Issues

When suppliers continue to provide CMRTs to Assent or F5 that list high risk, out of date, or other illegitimate smelters, F5 will follow up with that supplier and request that supplier work to remove those smelters from their supply chain. If a supplier submits a CMRT with issues and those issues persist over an 18 month period without being addressed, F5 will take corrective actions with that supplier up to and including removing them as an Approved Vendor from F5’s Approved Vendor List. For components that have multiple sources; preference will be given to suppliers that have submitted clear CMRTs.

Assent also directly contacts smelters and refiners that are not currently enrolled in the RMAP to encourage their participation and gather information regarding each facility's sourcing practices on behalf of its compliance partners. In the event after multiple attempts, a smelter does not engage in the RMAP, and a supplier continues to use metal from that smelter, F5 may entirely phase out the supplier.

While we were not successful in completely eliminating those smelters from our supply chain, we have seen a slight reduction in the number of suppliers claiming those smelters.

Public Reporting on Supply Chain Due Diligence

Results

During the reporting period, F5 had 214 actively purchased suppliers listed on our bills of materials. 138 of those in scope provided CMRTs that were accepted by F5, and an additional 59 were deemed out of scope. Six suppliers provided incomplete or invalid submissions. This represents a 93% percent response rate. With coverage above 90 percent, we feel we have met an acceptable threshold for F5 to consider the data gathering for the period to be complete and a success.

Attached as Appendix A is a list of all smelters and refiners listed by our suppliers in their completed CMRTs that appear on the lists of smelters maintained by the RMI. Most of the CMRTs we received from our suppliers were made on a company or division level basis, rather than on a product-level basis. Because we rely on data from our suppliers and not all suppliers are in each product, our list of processing smelters and refiners disclosed in Appendix A may contain more facilities than contained in any one of our products.

Appendix B includes an aggregated list of the countries of origin from which the reported facilities collectively source conflict minerals, based on information provided by suppliers and the RMI. As mentioned in the above section, many responses were

provided at the company level, therefore, Appendix B may contain more countries than those that our products are being sourced from.

Determination of Conflict Status

For the reporting period ending December 31, 2020, F5 has not been found to be conflict free. This determination stems primarily from two sources of concern:

•We still have smelters not listed as conflict free that are either located in or sourcing material in the conflict region.

•We did not undergo an independent third-party audit for the reporting period, and thus cannot declare ourselves conflict free.

As a downstream user of materials, F5 does not purchase directly from smelters, or even directly from metals suppliers. As such, we are primarily reliant on entities in our supply chain to perform actual in-person audits of smelters. We search through listings on industry group sites, including the RMI and iTSCi and leverage the findings of those groups in our reporting.

Next Steps

During calendar year 2020, we experienced significant delays in response from suppliers due to the global COVID-19 crisis. This significantly adversely impacted our ability to follow up with suppliers regarding invalid or problematic submissions. However, we were still able to achieve above 90% response rate. During 2021, we will continue to improve our process, particularly focusing on timing of requests to ensure there is an ability to report complete data.
