NOTICE OF 2022 ANNUAL MEETING OF STOCKHOLDERS

Dear Fortinet Stockholder:

Notice is hereby given that the 2022 Annual Meeting of Stockholders (the “2022 Annual Meeting”) of Fortinet, Inc., a Delaware corporation (“Fortinet,” “we,” “us” or “our”), will be held on Friday, June 17, 2022, at 10:00 a.m. Pacific time, in a virtual-only format, for the following purposes:

To elect the eight directors listed in the accompanying proxy statement to serve for a one-year term expiring at Fortinet’s 2023 Annual Meeting of Stockholders (the “2023 Annual Meeting”) and until their respective successors have been duly elected and qualified.

To ratify the appointment of Deloitte & Touche LLP as Fortinet’s independent registered public accounting firm for the fiscal year ending December 31, 2022.

An advisory vote to approve named executive officer compensation.

To adopt an amended and restated certificate of incorporation for Fortinet (the “Restated Certificate”) in order to implement a five-for-one forward stock split (the “Stock Split Proposal”) and to make certain other changes as reflected in the Restated Certificate and described in the Proxy Statement.

To vote on a stockholder proposal, if properly presented before the meeting.

To transact such other business proposals, if properly presented before the meeting.

We believe that a virtual stockholder meeting provides greater access to those who may want to attend and provides a safer forum in light of the ongoing COVID-19 pandemic, and therefore we have chosen this over an in-person meeting. We believe that hosting a virtual meeting will allow for greater stockholder attendance and participation from any location around the world. This approach also lowers costs and aligns with our broader sustainability goals.

The preceding items of business are more fully described in the proxy statement accompanying this notice. Any action on the items of business described above may be considered at the 2022 Annual Meeting at the time and on the date specified above or at any time and date to which the 2022 Annual Meeting may be properly adjourned or postponed. Only stockholders of record at the close of business on April 18, 2022 are entitled to notice of, and to vote at, the 2022 Annual Meeting.

We have elected to provide access to our proxy materials over the internet. Accordingly, stockholders of record at the close of business on April 18, 2022 will receive a Notice of Internet Availability of Proxy Materials and may vote at the 2022 Annual Meeting and any meetings pursuant to postponements or adjournments of the 2022 Annual Meeting. We expect to mail the Notice of Internet Availability of Proxy Materials on or about May 4, 2022.

TABLE OF CONTENTS

Your vote is very important. Whether or not you plan to attend the 2022 Annual Meeting, we encourage you to read the proxy statement and vote as instructed in the Notice of Internet Availability of Proxy Materials or vote on the internet or by telephone as soon as possible. Alternatively, you may follow the procedures outlined in the Notice of Internet Availability of Proxy Materials to request a paper copy of the proxy materials, which include a proxy card to submit your vote by mail. For specific instructions on how to vote your shares, please refer to the section entitled “Questions and Answers About the 2022 Annual Meeting and Procedural Matters” and the instructions on the Notice of Internet Availability of Proxy Materials.

Thank you for your ongoing support of Fortinet.

By Order of the Board of Directors,

Ken Xie
Chief Executive Officer and Chairman of the Board of Directors

PROXY STATEMENT
FOR 2022 ANNUAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THE 2022 ANNUAL MEETING AND PROCEDURAL MATTERS

Why am I receiving these materials?

The Board of Directors (the “Board of Directors”) of Fortinet, Inc. (“Fortinet,” “we,” “us” or “our”) is providing these proxy materials to you in connection with the solicitation of proxies for use at Fortinet’s 2022 Annual Meeting of Stockholders (the “2022 Annual Meeting”), to be held on Friday, June 17, 2022 at 10:00 a.m. Pacific time, and at any adjournment or postponement thereof, for the purpose of considering and acting upon the matters set forth in this proxy statement.

We expect to mail the Notice of Internet Availability of Proxy Materials (the “Notice”) on or about May 4, 2022. Copies of our proxy materials and 2021 Annual Report are available at www.edocumentview.com/FTNT .

Due to the public health risk of the COVID-19 pandemic and to support the health and well-being of our stockholders and other meeting participants, the 2022 Annual Meeting will be held in a virtual-only format. We believe that hosting a virtual meeting will allow for greater stockholder attendance and participation from any location around the world. The virtual-only approach also lowers costs and aligns with our broader sustainability goals. You will not be able to attend the 2022 Annual Meeting in person.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. Accordingly, we are sending the Notice to our stockholders of record and beneficial owners. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis.

How can I get electronic access to the proxy materials?

The Notice will provide you with instructions regarding how to:

•

View our proxy materials for the 2022 Annual Meeting on the internet; and

•

Have future proxy materials sent to you electronically by email.

Choosing to receive future proxy materials by email will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site.

Can I attend the 2022 Annual Meeting?

If you were a stockholder of record at the close of business on April 18, 2022 (the “Record Date”) (i.e., your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A. (“Computershare”)) or if you are a proxy holder for such a stockholder, you may participate in the 2022 Annual Meeting by following the instructions below:

•

TABLE OF CONTENTS

•

Enter the 15-digit control number on the Proxy Card or Notice of Availability of Proxy Materials you receive.

If you held your shares through an intermediary on the Record Date (i.e., you hold your shares in “street name” through an intermediary, such as a bank or broker), you must register in advance to virtually attend the 2022 Annual Meeting by following the instructions below:

•

You must obtain a legal proxy, executed in your favor, from the holder of record reflecting the number of shares of common stock you held as of the Record Date, along with your name and email address.

Requests for registration must be labeled as “Legal Proxy” and be received no later than 5:00 p.m. Eastern Time, on June 10, 2022.

In any situation, we will promptly notify stockholders of the decision via www.meetnow.global/MVG5Z49. The virtual meeting platform is fully supported across most browsers (including Edge, Firefox, Chrome and Safari) and devices (including desktops, laptops, tablets and cell phones) running the most up-to-date version of applicable software and plugins.

Who is entitled to vote at the 2022 Annual Meeting?

You may vote your shares of Fortinet common stock if our records show that you owned your shares at the close of business on the Record Date. At the close of business on the Record Date, there were 160,268,931 shares of Fortinet common stock outstanding and entitled to vote at the 2022 Annual Meeting. You may cast one vote for each share of common stock held by you as of the Record Date on all matters presented.

What is the difference between holding shares as a stockholder of record or as a beneficial owner?

With respect to your shares that are registered directly in your name with Fortinet’s transfer agent, Computershare, you are considered the “stockholder of record” and the Notice has been sent directly to you by Fortinet. As the stockholder of record, you have the right to grant your voting proxy directly to Fortinet or to a third party, or to vote in person at the 2022 Annual Meeting.

With respect to your shares that are held by a brokerage account or by another nominee, you are considered the “beneficial owner” of shares held in “street name” and the Notice is being forwarded to you together with voting instructions on behalf of your broker, trustee or nominee. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to vote, and you are also invited to attend the 2022 Annual Meeting. Your broker, trustee or nominee has enclosed or provided voting instructions for you to use in directing the broker, trustee or nominee how to vote your shares. Because a beneficial owner is not the stockholder of record, you may not vote these shares in person at the 2022 Annual Meeting unless you obtain a “legal proxy” from the broker, trustee or nominee that holds

If you hold your shares through a broker and do not provide your broker with specific voting instructions, under the rules that govern brokers in such circumstances, your broker will have the discretion to vote such shares on routine matters but not on non-routine matters. Even though we are listed on The Nasdaq Stock Market LLC (“Nasdaq”), the rules of the New York Stock Exchange (the “NYSE”) govern how a broker licensed by the NYSE can vote shares it holds on behalf of stockholders of Nasdaq-listed companies.

As a result:

•

Your broker will not have the authority to exercise discretion to vote your shares with respect to the election of directors, the advisory vote on named executive officer compensation or the stockholder proposal.

•

Your broker will have the authority to exercise discretion to vote your shares with respect to the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2022 and the vote on the Stock Split Proposal, because those matters are treated as routine under NYSE rules.

Because the proposals to be acted upon at the 2022 Annual Meeting include both routine and non-routine matters, if you do not give voting instructions to your broker, trustee or nominee, your broker, trustee or nominee may either (i) vote your shares on routine matters or (ii) leave your shares unvoted.

A broker “non-vote” occurs when your broker, trustee or nominee does not vote on a particular proposal because the broker, trustee or nominee does not have discretionary voting power with respect to that item and has not received voting instructions from you as the beneficial owner.

How can I vote my shares without attending the 2022 Annual Meeting?

You are encouraged to vote your shares in advance of the 2022 Annual Meeting. If voting in advance of the 2022 Annual Meeting, the steps required to cast your votes are the same as indicated in the materials received with the Proxy Statement. If you have not already voted your shares in advance, you will be able to vote your shares electronically during the 2022 Annual Meeting by clicking on the “Cast Your Vote” link on the Meeting Center site.

Whether you hold shares directly as the stockholder of record or beneficially in street name, you may direct how your shares are voted without attending the 2022 Annual Meeting. There are three ways to vote by proxy:

By mail — If you are a stockholder of record, you may vote by submitting a proxy card; please refer to the voting instructions in the Notice or below. If you hold shares beneficially in street name, you may vote by submitting voting instructions to your broker, trustee or nominee; please refer to the voting instructions provided to you by your broker, trustee or nominee.

By internet — Stockholders of record of Fortinet common stock with internet access may submit proxies by following the “Vote by Internet” instructions described in the Notice until 11:59 p.m. Eastern time on Thursday, June 16, 2022 or by following the instructions at www.meetnow.global/MVG5Z49 . Most Fortinet stockholders who hold shares beneficially in street name may vote by accessing the website specified in the voting instructions provided by their brokers, trustees or nominees. Please check the voting instructions for internet voting availability.

By telephone — Depending on how your shares are held, you may be able to vote by telephone. If this option is available to you, you will have received information with the Notice or the voting instruction card provided by your broker, trustee or nominee explaining this procedure.

How many shares must be present or represented to conduct business at the 2022 Annual Meeting?

The presence of the holders of a majority of the issued and outstanding shares of our capital stock entitled to vote at the 2022 Annual Meeting is necessary to constitute a quorum at the 2022 Annual Meeting. Such stockholders are counted as present at the meeting if they (i) are present in person at the 2022 Annual Meeting or (ii) represented by proxy.

TABLE OF CONTENTS

Under Delaware law, abstentions and broker non-votes are counted as present and entitled to vote for purposes of determining whether a quorum is present at the 2022 Annual Meeting. However, as discussed above, under “What is the difference between holding shares as a stockholder of record or as a beneficial owner?” brokers have limited discretionary authority to vote shares that are beneficially owned and, therefore, are not entitled to vote on non-routine matters in the absence of voting instructions from the beneficial owner of such shares.

What proposals will be voted on at the 2022 Annual Meeting?

The proposals scheduled to be voted on at the 2022 Annual Meeting are:

•

The election of the nine directors set forth in Proposal One to serve for a one-year term expiring at the 2023 Annual Meeting and until their respective successors are duly elected and qualified;

•

The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022;

•

An advisory vote to approve our named executive officer compensation;

•

The Stock Split Proposal; and

•

A stockholder proposal, if properly presented before the meeting.

What is the voting requirement to approve each of the proposals?

We have a majority voting standard for uncontested elections of directors (Proposal One), which means that to be elected, a director nominee must receive a majority of the votes cast, i.e. the number of shares voted “FOR” a director nominee must exceed the votes cast “AGAINST” that nominee.

The affirmative vote of a majority of the shares of our common stock that are present in person or represented by proxy at the 2022 Annual Meeting and entitled to vote is required to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm (Proposal Two), to approve the advisory resolution on named executive compensation (Proposal Three) and to approve the stockholder proposal (Proposal Five).

For the Stock Split Proposal, the affirmative vote of at least 66 2 ∕ 3 % of the voting power of all of the shares of our common stock outstanding as of the Record Date is required to adopt the Restated Certificate in order to implement the proposed stock split (Proposal Four).

How are votes counted?

You may vote “FOR” or “AGAINST” each of the nominees for election as director in Proposal One and on each of Proposal Two, Proposal Three, Proposal Four and Proposal Five. You may also “ABSTAIN” from voting.

Abstentions are deemed to be shares present or represented by proxy and entitled to vote. Abstentions have no effect on Proposal One and the same effect as a vote against Proposals Two, Three, Four and Five .

Broker non-votes are not deemed to be shares entitled to vote on and will have no effect on Proposals One and Three. Brokers have discretionary authority to vote shares that are beneficially owned on Proposal Two and Proposal Four. If a broker chooses not to vote shares for or against Proposal Two or Proposal Four, it would have the same effect as an abstention.

All shares entitled to vote and represented by properly submitted proxies received prior to the 2022 Annual Meeting (and not revoked) will be voted at the 2022 Annual Meeting in accordance with the instructions indicated by such proxy. If no instructions are indicated on such proxy, the shares represented by that proxy will be voted as recommended by the Board of Directors.

How does the Board of Directors recommend that I vote?

The Board of Directors recommends that you vote your shares:

•

“ FOR ” each of the nine nominees for election as directors (Proposal One);

TABLE OF CONTENTS

•

“ FOR ” the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022 (Proposal Two);

•

“ FOR ” the advisory resolution to approve named executive officer compensation (Proposal Three); and

•

“ FOR ” the Stock Split Proposal (Proposal Four).

The Board of Directors has no voting recommendation for the stockholder proposal (Proposal Five).

What happens if additional matters are presented at the 2022 Annual Meeting?

If any other matters are properly presented for consideration at the 2022 Annual Meeting, including, among other things, consideration of a motion to adjourn the 2022 Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named as proxy holders, Ken Xie and John Whittle, or either of them, will have discretion to vote on those matters in accordance with their best judgment. Fortinet does not currently anticipate that any other matters will be raised at the 2022 Annual Meeting.

Can I change my vote?

Subject to any rules your broker, trustee or nominee may have, you may change your proxy instructions at any time before your proxy is voted at the 2022 Annual Meeting.

If you are the stockholder of record, you may change your vote: (i) by granting a new proxy bearing a later date (which automatically revokes the earlier proxy) using any of the methods described above (and until the applicable deadline for each method); (ii) by providing a written notice of revocation to Fortinet’s Corporate Secretary at Fortinet, Inc., 899 Kifer Road, Sunnyvale, California 94086 prior to your shares being voted; or (iii) by attending the 2022 Annual Meeting and voting virtually. Attendance at the meeting will not cause your previously granted proxy to be revoked unless you specifically so request.

If you are a beneficial owner of shares held in street name, you may change your vote (a) by submitting new voting instructions to your broker, trustee or nominee or (b) if you have obtained a legal proxy from the broker, trustee or nominee that holds your shares giving you the right to vote your shares, by attending the 2022 Annual Meeting and voting virtually.

What should I do if I receive more than one set of voting materials?

If you received more than one Notice, voting instruction card or set of proxy materials, your shares are registered in more than one name or brokerage account. Please follow the instructions on each Notice or voting instruction card that you receive to ensure that all of your shares are voted.

Is my vote confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within Fortinet or to third parties, except: (i) as necessary to meet applicable legal requirements; (ii) to allow for the tabulation of votes and certification of the vote; and (iii) to facilitate a successful proxy solicitation. Occasionally, stockholders provide written comments on their proxy cards, which may be forwarded to Fortinet management.

Who will serve as inspector of election?

The inspector of election will be a representative of Computershare.

Where can I find the voting results of the 2022 Annual Meeting?

We will announce preliminary voting results at the 2022 Annual Meeting. We will disclose final voting results in a Current Report on a Form 8-K filed with the SEC within four business days after the 2022 Annual Meeting.

TABLE OF CONTENTS

Who will bear the cost of soliciting votes for the 2022 Annual Meeting?

Fortinet will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials and soliciting votes. We may reimburse brokerage firms, custodians, nominees, fiduciaries and other persons representing beneficial owners for their reasonable expenses in forwarding solicitation material to such beneficial owners. Our directors, officers and employees may also solicit proxies in person or by other means of communication. Such directors, officers and employees will not be additionally compensated but may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation.

What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors?

You may submit proposals, including nominations of director candidates, for consideration at future stockholder meetings.

For inclusion in Fortinet’s proxy materials — Stockholders may present proper proposals for inclusion in Fortinet’s proxy statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to Fortinet’s Corporate Secretary in a timely manner. In order to be included in the proxy statement for the 2023 Annual Meeting, stockholder proposals must be received by Fortinet’s Corporate Secretary no later than January 2, 2023, and must otherwise comply with the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

To be brought before the annual meeting — In addition, Fortinet’s amended and restated bylaws establish an advance notice procedure for stockholders who wish to present certain matters before an annual meeting of stockholders. In general, nominations for the election of directors may be made (i) by or at the direction of the Board of Directors or (ii) by a stockholder who has delivered written notice to Fortinet’s Secretary within the Notice Period (as defined below) and who was a stockholder at the time of such notice and as of the record date. The notice must contain specified information about the nominees and about the stockholder proposing such nominations.

Fortinet’s amended and restated bylaws also provide that the only business that may be conducted at an annual meeting is business that is (a) properly brought before the meeting pursuant to Fortinet’s proxy materials with respect to such meeting, (b) properly brought before the meeting by or at the direction of the Board of Directors or (c) properly brought before the meeting by a stockholder who has delivered written notice to Fortinet’s Corporate Secretary at its principal executive offices within the Notice Period and who was a stockholder at the time of such notice and as of the record date. The notice must contain specified information about the matters to be brought before such meeting and about the stockholder proposing such matters.

The “Notice Period” is defined as that period not less than 45 days nor more than 75 days prior to the one-year anniversary of the date on which Fortinet mailed its proxy materials or the Notice (whichever is earlier) to stockholders in connection with the preceding year’s annual meeting of stockholders. As a result, assuming a Notice mailing date of May 4, 2022, the Notice Period for the 2023 Annual Meeting will start on February 18, 2023 and end on March 20, 2023.

If a stockholder who has notified Fortinet of such stockholder’s intention to present a proposal at an annual meeting does not appear to present such stockholder’s proposal at such meeting, Fortinet need not present the proposal for vote at such meeting.

A copy of the full text of the bylaw provisions discussed above may be obtained by writing to Fortinet’s Corporate Secretary at our principal executive offices or by accessing Fortinet’s filings on the SEC’s website at www.sec.gov . All notices of proposals by stockholders, whether or not included in Fortinet’s proxy materials, should be sent to Fortinet’s Corporate Secretary at our principal executive offices.

How may I obtain a separate set of proxy materials or the 2021 Annual Report?

If you share an address with another stockholder, each stockholder may not receive a separate copy of our proxy materials and 2021 Annual Report. Stockholders who do not receive a separate copy of

PROPOSAL ONE

ELECTION OF DIRECTORS

General

The Board of Directors currently consists of nine members, and our amended and restated certificate of incorporation provides that the entire Board of Directors will stand for election annually for one-year terms. Each director holds office until that director’s successor is duly elected and qualified. Our amended and restated bylaws permit the Board of Directors to establish by resolution the authorized number of directors, and nine directors are currently authorized.

Nominees

Eight candidates have been nominated for election as directors at the 2022 Annual Meeting for a one-year term expiring at the 2022 Annual Meeting. Upon recommendation of the Governance Committee of the Board of Directors (the “Governance Committee”), the Board of Directors has nominated Ken Xie, Michael Xie, Kenneth A. Goldman, Ming Hsieh, Jean Hu, William H. Neukom, Judith Sim and Admiral James Stavridis (Ret) for election as directors. Biographical information about each of the nominees is contained in the following section. A discussion of the qualifications, attributes and skills of each nominee that led the Board of Directors and the Governance Committee to the conclusion that such nominee should serve as a director has been added following each of the director and nominee biographies.

Kelly Ducourty has decided not to stand for re-election at the 2022 Annual Meeting. We thank Ms. Ducourty for her distinguished service.

Each nominee has agreed to serve if elected, and management has no reason to believe that any nominee will be unavailable to serve. In the event any nominee is unable or declines to serve as a director at the time of the 2022 Annual Meeting, the proxies will be voted for any nominee who may be proposed by the Governance Committee and designated by the present Board of Directors to fill the vacancy.

If you sign your proxy card or voting instruction card or vote by telephone or over the internet but do not give instructions with respect to the voting of directors, your shares will be voted for the nine nominees recommended by the Board of Directors. If you wish to give specific instructions with respect to the voting of directors, you may do so by indicating your instructions on your proxy or voting instruction card or when you vote by telephone or over the internet.

Director Expertise and Experience

The Board of Directors is comprised of a diverse mix of directors with complementary expertise and experience, as summarized in the table below. Our directors may also have limited expertise and experience in addition to what is reflected in the “Number of Directors” column below. The “Number of Directors” columns below include Kelly Ducourty, who has decided not to stand for re-election at the 2022 Annual Meeting and whose term as a director will end at the 2022 Annual Meeting.

Director Tenure and Age Distribution

We also believe that our current Board of Directors composition represents an effective balance with respect to director tenure and age. Recent director additions provide the Board of Directors with fresh perspectives and diverse experiences, while directors with longer tenure provide continuity and valuable insight into our business and strategy. The following tables provide information regarding the current tenure and age distribution of the Board of Directors (as of March 31, 2022). The following tables include Kelly Ducourty, who has decided not to stand for re-election at the 2022 Annual Meeting and whose term as a director will end at the 2022 Annual Meeting.

Board Evaluations

The Board of Directors is committed to a robust self-evaluation process designed for continuous improvement. To achieve this, the Board of Directors conducts an annual self-evaluation for itself and its committees. As part of this process, each member of the Board of Directors completes a survey conducted by a third-party consulting firm to provide feedback on the processes, structure, composition and effectiveness of the Board of the Directors. The survey is a detailed written questionnaire designed to help the Board of Directors assess the performance of the Board of Directors and its committees, their own individual performance and the individual performances of fellow directors. The third-party consulting firm also collects feedback on the Board of Directors as a whole and each individual director from key members of management. The feedback received from the Board of Directors and management is shared first with the Governance Committee, and then made available to the individual directors and the full Board of Directors.

The Board of Directors evaluation process is used:

•

by the Board of Directors and the Governance Committee to assess the current composition of the Board of Directors and its committees and make recommendations for the qualifications, expertise and characteristics we should seek in identifying potential new directors;

•

by the Board of Directors and the Governance Committee to identify the strengths and areas of opportunity of each member of the Board of Directors, the Board of Directors as a whole and each committee;

•

by the Board of Directors to provide insight into how the Board as a whole, each committee and each member of the Board of Directors can be most valuable;

•

to improve agenda topics of the Board of Directors and its committees so that information they receive enables them to effectively address the issues they consider most critical; and

•

by the Governance Committee as part of its annual review of each director’s performance when considering whether to recommend the nomination of the director for re-election to the Board of Directors.

See “ Corporate Governance ” and “ Executive Compensation — Compensation of Directors ” for additional information regarding the Board of Directors.

PROPOSAL TWO

RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

General

The Audit Committee of the Board of Directors (the “Audit Committee”) has selected Deloitte & Touche LLP as Fortinet’s independent registered public accounting firm to audit the financial statements of Fortinet for the fiscal year ending December 31, 2022, which will include an audit of the effectiveness of Fortinet’s internal control over financial reporting.

PROPOSAL THREE

ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

As required by Section 14A of the Exchange Act and the corresponding rules of the SEC, Fortinet is seeking stockholder approval, on an advisory and non-binding basis, of the compensation of our named executive officers as disclosed in accordance with the SEC’s rules in the “ Executive Compensation ” section of this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer but rather the overall compensation of all of our named executive officers and the compensation philosophy, policies and practices described in this proxy statement.

The say-on-pay vote is advisory, and therefore not binding on Fortinet, the Human Resources Committee or the Board of Directors. Following the 2022 Annual Meeting, the next such non-binding advisory vote to approve our named executive officers’ compensation as a whole is scheduled to occur at the 2023 Annual Meeting.

The Board of Directors and the Human Resources Committee value the opinions of our stockholders and the say-on-pay vote provides information to us regarding stockholder sentiment about our executive compensation philosophy, policies and practices, which the Human Resources Committee will be able to consider when determining executive compensation for the remainder of the current fiscal year and beyond. To the extent there is any significant vote against the compensation of our named executive officers as disclosed in this proxy statement, we will consider our stockholders’ concerns, and the Human Resources Committee will evaluate whether any actions are necessary to address those concerns. We believe that the information we have provided in the “ Executive Compensation ” section of this proxy statement, and in particular the information discussed in “ Executive Compensation — Compensation Discussion and Analysis, ” demonstrates that our executive compensation program was designed appropriately and is working to ensure our executive officers’ interests are aligned with our stockholders’ interests. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the 2022 Annual Meeting:

“RESOLVED, that Fortinet’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in Fortinet’s proxy statement for the 2022 Annual Meeting pursuant to the Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion and the other related disclosure.”

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THIS PROPOSAL.

PROPOSAL FOUR

ADOPTION OF AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO IMPLEMENT FIVE-FOR-ONE FORWARD STOCK SPLIT

The Board of Directors has deemed it advisable and in the best interests of our stockholders to effect a five-for-one forward split of our common stock. The trading price of our common stock has experienced significant growth since our initial public offering in 2009. The Board of Directors regularly evaluates the effect of such growth on the liquidity and marketability of our common stock and believes the considerable appreciation in the trading price of our common stock makes our common stock less affordable on a per-share basis to certain of our investors and employees. The per share closing stock price of our common stock on March 31, 2022 was $341.74. The Board of Directors believes effecting a five-for-one stock split would make our shares more affordable, attract a broader group of potential investors and employees and increase liquidity in the trading of shares of our common stock.

At present, our amended and restated certificate of incorporation authorizes the issuance of up to 300,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share. As of March 31, 2022, 160,266,932 shares of common stock were issued and outstanding. Of the unissued shares, approximately 17,131,647 shares of common stock were reserved for issuance under our Amended and Restated 2009 Equity Incentive Plan (the “2009 Plan”). No shares of preferred stock have been issued.

On April 14, 2022, subject to approval by our stockholders, the Board of Directors approved the Restated Certificate, which: (i) effects a five-for-one forward stock split of our common stock (the “Stock Split”); (ii) proportionally increases the number of authorized shares of our common stock from 300,000,000 to 1,500,000,000 (the “Share Increase”); and (iii) makes certain other changes to our existing amended and restated certificate of incorporation in order to remove certain no longer applicable provisions thereof relating to the transition from the classified Board of Directors that we had prior to 2018 to the declassified Board of Directors that is now in place. The additional shares of common stock would have rights identical to the currently outstanding common stock.

The Board of Directors recommends that our stockholders approve the Restated Certificate in order to effect the Stock Split and the Share Increase. A copy of the Restated Certificate is attached as Appendix B to this Proxy Statement, which Restated Certificate also sets forth the procedure for the Stock Split. Additions to our existing amended and restated certificate of incorporation are indicated by underlining, and deletions are indicated by strikethroughs.

If our stockholders approve the Restated Certificate, the Stock Split and Share Increase would become effective upon the filing and effectiveness of the Restated Certificate with the Secretary of State of the State of Delaware. It is expected that this filing will take place promptly following the stockholders’ approval of the Restated Certificate. The Board of Directors reserves the right, notwithstanding stockholder approval and without further action by our stockholders, to elect not to proceed with the Stock Split and Share Increase if, at any time prior to filing the Restated Certificate, the Board of Directors, in its sole discretion, determines that it is no longer in our best interests and the best interests of our stockholders to proceed with the Stock Split and Share Increase.

Upon filing and effectiveness of the Restated Certificate with the Secretary of State of the State of Delaware effecting the Stock Split and Share Increase, the Stock Split and Share Increase shall occur without any further action on the part of Fortinet or the holders of shares of our common stock. Book-entries dated as of a date prior to the effective time of the Stock Split representing outstanding shares of common stock shall, immediately after the effective time of the stock split, represent a number of shares equal to the same number of shares of common stock as is reflected on the book-entries, multiplied by five.

Following the Stock Split, if ultimately implemented, we currently estimate that we will have approximately 801,344,655 shares of common stock outstanding, based on the number of shares of common stock that were issued and outstanding as of the Record Date. We also will have reserved for issuance the maximum number of shares of common stock subject to options and other awards which have been granted or may be granted under the 2009 Plan, which provide that the number of shares of common stock reserved for issuance shall be appropriately adjusted in the event of a stock split.

TABLE OF CONTENTS

The Board of Directors believes it is in our best interests to increase proportionately the number of authorized shares of common stock so as to accommodate the Stock Split and so as to have additional authorized but unissued shares available for issuance by the Board of Directors in connection with any future stock dividends or splits, grants under the 2009 Plan, financings, mergers or acquisitions and for other general corporate purposes without the delay and expense associated with convening a special stockholders’ meeting or soliciting stockholders’ written consents. Aside from the shares currently reserved or to be reserved for issuance under the 2009 Plan, the Board of Directors has not authorized the issuance of any additional shares of common stock, and there are no current agreements or commitments for the issuance of additional shares.

Stockholders’ current ownership of common stock will not give them automatic rights to purchase any of the additional authorized shares of common stock. If the Restated Certificate is adopted, the additional authorized shares of common stock will be available for issuance from time to time at the discretion of the Board of Directors without further action by the stockholders, except where stockholder approval is required by Nasdaq or to obtain favorable tax treatment for certain employee benefit plans. Article IV of our amended and restated certificate of incorporation authorizes the Board of Directors, without further stockholder approval, to issue preferred stock having such designations, powers, preferences and rights as may be determined by the Board of Directors. Any future issuance of additional authorized shares of common stock may, among other things, dilute the earnings per share of the common stock and the equity and voting rights of those holding common stock at the time the additional shares are issued. Issuance of shares of preferred stock would dilute the earnings per share and book value per share of existing shares of common stock. Holders of preferred stock would have such voting rights as may be provided for by law and as determined by the Board of Directors.

Although an increase in the authorized shares of common stock could, under certain circumstances, be construed as having an anti-takeover effect (for example, by diluting the stock ownership of a person seeking to effect a change in the composition of the Board of Directors or contemplating a tender offer or other transaction for the combination of our company with another company), the Board of Directors is not proposing to adopt the Restated Certificate in response to any effort to accumulate our stock or obtain control of the company by means of a merger, tender offer or solicitation in opposition of management. Also, while we have no present intention to issue shares of preferred stock in a manner which would have an anti-takeover effect or otherwise, the issuance of preferred stock could have certain other anti-takeover effects under certain circumstances. Since the voting rights to be accorded to any series of preferred stock remain to be fixed by the Board of Directors, the holders of preferred stock may be authorized by the Board of Directors to vote separately as a class in connection with approval of certain extraordinary corporate transactions or be given a large number of votes per share. Such preferred stock could also be convertible into a large number of shares of common stock under certain circumstances or have other terms which might render the acquisition of a controlling interest in us more difficult or more costly. Shares of preferred stock could be privately placed with purchasers who might side with the management of Fortinet in opposing a hostile tender offer or other attempt to obtain control. The issuance of preferred stock as an anti-takeover device might preclude stockholders from taking advantage of a situation which might be favorable to their interests.

As set forth our amended and restated certificate of incorporation, the affirmative vote of the holders of at least 66 2 ∕ 3 % of the voting power of all of the shares of our common stock outstanding as of the Record Date is required for approval of the Restated Certificate.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THIS PROPOSAL.

PROPOSAL FIVE

THE BOARD OF DIRECTORS HAS NO VOTING RECOMMENDATION FOR
THE FOLLOWING STOCKHOLDER PROPOSAL

Management has been advised that John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, intends to submit the following proposal at the meeting.

Stockholder Proposal

Proposal Five — Simple Majority Vote

RESOLVED, Shareholders request that our board take the necessary steps so that each voting requirement in our charter and bylaws (that is explicit or implicit due to default to state law) that calls for a greater than simple majority vote be replaced by a requirement for a majority of the votes cast for and against such proposals, or a simple majority in compliance with applicable laws. If necessary this means the closest standard to a majority of the votes cast for and against such proposals consistent with applicable laws. This includes any existing supermajority vote requirement that results from default to state law and can be subject to elimination.

Shareholders are willing to pay a premium for shares of companies that have excellent corporate governance. Supermajority voting requirements have been found to be one of 6 entrenching mechanisms that are negatively related to company performance according to “What Matters in Corporate Governance” by Lucien Bebchuk, Alma Cohen and Allen Ferrell of the Harvard Law School. Supermajority requirements are used to block proposals supported by most shareholders but opposed by a status quo management.

This proposal topic won from 74% to 88% support at Weyerhaeuser, Alcoa, Waste Management, Goldman Sachs, FirstEnergy, McGraw-Hill and Macy’s. The proponents of these proposals included Ray T. Chevedden and William Steiner. The votes would have been higher than 74% to 88% if more shareholders had access to independent proxy voting advice.

Church & Dwight shareholders gave 99% support to a 2020 proposal on this same topic. This proposal topic also won 99%-support at the 2021 Conoco Phillips annual meeting.

Currently Fortinet has a 67% vote requirement. This means that an 87% vote from the shares that vote at the Fortinet annual meeting are required to meet the 67% voting requirement — an almost impossible requirement.

This is not the only shortcoming in Fortinet corporate governance. Mr. Kenneth Goldman joined the Fortinet Board of Directors in October 2020 and received 40 times the negative votes as most of the other Fortinet directors in 2021.

Please vote yes:

Simple Majority Vote — Proposal Five

Voting Requirement to Approve Proposal

The affirmative vote of a majority of the shares of our common stock that are present in person or represented by proxy at the 2022 Annual Meeting and entitled to vote is required to approve Proposal Five.

Board of Directors’ Response

The Board of Directors has considered the proposal set forth above relating to the removal of supermajority voting standards in our amended and restated certificate of incorporation and amended and restated bylaws and has determined to make no voting recommendation to our stockholders. The proposal is advisory in nature only. Stockholders should note that approval of this proposal would not, by itself, implement a majority voting standard as described in the proposal, and the Board of Directors and our

TABLE OF CONTENTS

stockholders would need to take subsequent action to amend our amended and restated certificate of incorporation and/or our amended and restated bylaws.

The affirmative vote of a majority of the voting power of the shares present in person or represented by proxy at a meeting and entitled to vote on the subject matter is the voting standard for nearly all matters voted upon by our stockholders. Our use of supermajority voting standards is limited in our amended and restated certificate of incorporation and our amended and restated bylaws solely to certain amendments of each such governing document. This limited use of supermajority voting standards has been approved by our stockholders on multiple occasions, most recently at our 2018 Annual Meeting of Stockholders when stockholders approved our current amended and restated certificate of incorporation by 99% of shares present at the meeting (i.e. excluding broker non-votes). We believe higher voting requirements are appropriate in limited circumstances because certain fundamental matters should require broad support and consensus from our stockholders. In addition, under a majority voting standard as proposed, holders of a significant minority of our outstanding shares could approve certain fundamental corporate changes without broad stockholder support, as a mere majority of the votes cast at a meeting could in many cases represent significantly less than a majority of our shares outstanding.

However, we recognize that some stockholders prefer a universal majority voting standard. As such, we want to use this proposal as an opportunity for stockholders to express their views on this subject. We will consider the voting results on this proposal, together with additional stockholder input received in the course of our regular stockholder engagement program, in our future deliberations regarding the appropriate voting standards within our amended and restated certificate of incorporation and our amended and restated bylaws.

THE BOARD OF DIRECTORS TAKES NO POSITION AND MAKES NO RECOMMENDATION ON THIS PROPOSAL. PROXIES RETURNED WITHOUT VOTING INSTRUCTIONS WILL BE VOTED AGAINST THIS PROPOSAL.

CORPORATE SOCIAL RESPONSIBILITY

We believe that our corporate vision — a digital world you can always trust — is essential to achieving just and sustainable societies, and that it is our responsibility to deliver on that vision by innovating sustainable security technologies, diversifying cybersecurity talent and promoting responsible business across our value chain. This responsibility drives our ESG practices.

Our commitment to CSR starts at the highest level with the Social Responsibility Committee, which the Board of Directors established on its own initiative in 2021 to ensure proper focus on, and provide proper oversight of, our CSR strategy, initiatives and execution. Our senior leadership sponsors and helps oversee the integration of our CSR priorities broadly throughout our business operations, and our Global Head of Sustainability & CSR manages a team and chairs an internal cross-functional employee CSR Committee to define our CSR strategy and lead execution.

Our objective is to promote long-term value for our stakeholders, including customers, partners, suppliers, employees, stockholders and communities. In 2021, we conducted a formal materiality assessment with outside experts, which informed our sustainability strategy as follows:

Innovating for a Safe Internet	Growing an Inclusive Cybersecurity Workforce	Promoting Responsible Business	Respecting the Environment
We believe that ensuring the digital security and privacy of individuals and organizations enables digital progress, and we strive to create value through security innovation, expertise, research and cooperation.	We are committed to building an inclusive, equitable and diverse workforce within our organization and across the industry to help empower individuals to reach their full potential.	We are committed to doing business ethically and in compliance with all laws. Our corporate governance practices aim to ensure accountability to meet our responsibilities across our entire value chain.	We are focused on addressing the climate change impacts and minimizing the environmental footprint of our solutions, operations and our broader value chain.
Priority issues: Cyber Risks to Society; Information Security & Privacy	Priority issues: Diversity, Equity & Inclusion; Cybersecurity Skills Gap	Priority issues: Business Ethics; Responsible Product Use	Priority issues: Product Environmental Impacts; Climate Change

In 2021, for each of our defined CSR priorities we developed initial roadmaps and engaged our relevant business units in the process. We improved transparency and disclosure by actively participating in third-party sustainability assessments with selected rating agencies and bolstering our public CSR disclosures, including on our public website. This year, we intend to publish our first sustainability report which will further outline our CSR strategy, governance, performance and future outlook.

We engage with key internal and external stakeholders to help refine our ESG practices. Below are specific areas that we know are of particular importance to many of our stockholders based on the feedback received.

Environment

Our business strategy has always promoted the reduction of the environmental footprint of our customers by innovating highly efficient, integrated appliances and cloud-based security solutions. From our inception, our strategy has been to leverage the power of our internally developed, high-performance, purpose-built security processors to integrate into one-product multiple networking and security functionalities that traditionally have been in multiple products and appliances that require more space, cooling and electricity. In 2021, we conducted a competitive analysis on power consumption, which demonstrated the superior energy efficiency of our appliances as a result of our continued innovation on product design, including the high performance of our purpose-built security processors. We have started to work with our contract manufacturers to eliminate plastics from selected product packaging and to use

TABLE OF CONTENTS

recyclable and biodegradable materials instead. We also continued to ensure that our products comply with global product environmental compliance directives and regulations, from the design phase to final disposition of waste.

In order to drive sustainable operations, we engaged with a consultant to measure our Scope 1 and Scope 2 emissions and developed reduction scenarios based on science-based targets. This work allowed us to publicly commit to achieving carbon neutrality by 2030 for emissions resulting from the facilities we own worldwide. We took concrete action on environmental sustainability with the completion of our new net-zero Sunnyvale headquarter campus, which is on track to be LEED-Gold certified. We implemented multiple energy efficiency measures in this all-electric, net-zero facility, including solar panels and radiant cooling, which uses 30% less energy than a standard building and conserves 76,800 gallons of water annually. We use renewable electricity across our owned facilities, invest in sustainable projects and incentivize employees to reduce their environmental footprint by providing bike racks, onsite solar-powered electric vehicle charging stations and preferred parking spaces for sustainable-energy vehicles.

In order to increase transparency of our sustainability commitments, we developed and published our Environmental Policy and assessed climate risks from a risk factor and disclosure perspective. We have been working to automate metrics and reporting on environmental management in order to help pursue our carbon footprint reduction. This year, we are conducting an assessment of our Scope 3 emissions to help reduce carbonization in our broader value chain, and we plan to set reduction targets in alignment with the SBTi methodology. Actions such as these will help us with our strategy on climate change with the aim of implementing a framework that aligns with the Task Force on Climate Related Financial Disclosures.

Social

Since the publication of our first Diversity & Inclusion Report in March 2021, we have further engaged with internal and external subject matter experts and certain stockholders to continue to refine and improve our approach to Diversity, Equity and Inclusion (“DEI”). To increase transparency and visibility, we published our EEO-1 report and created gender diversity reports for senior leadership in the research and development, sales and support organizations. In order to improve equity pay, we worked with external consultants to align our salary ranges per job function and grade with industry practice. We have continued to expand programs designed to ensure DEI in the workplace, including our unconscious bias training for managers across the company and Fortinet’s Conversations , a management program designed to drive broad and diverse employee engagement, development and performance. We initiated workshops on building an inclusive team and published internally an Inclusive Leadership Guide .

We also take steps to consider diversity and inclusion while contributing to close the global cybersecurity skills gap. Last year, we formalized our Education Outreach Program , which focuses on partnerships across the industry, academia, government and nonprofits to help provide cybersecurity training and job skills to all populations, with a particular focus on women, veterans and other under-represented groups. To support the creation of a cybersecurity-aware society and help bridge the global cybersecurity skills gap, in 2021, we published a children’s book designed to further increase cyber awareness among children and extended our free cybersecurity training courses, thereby allowing over 100,000 people from over 200 countries and territories to benefit from our cybersecurity fundamentals training courses. We also made the public pledge to train one million people in cybersecurity by 2026.

We have also contributed to help address the “digital divide” by providing fast and secure network access to public library systems and to help bridge the “homework gap” by delivering an affordable solution for reliable and secure broadband access for K-12 students.

Governance

We are focused on good governance and ethical practices throughout our business. Our Board of Directors frequently reviews our governance practices to ensure that they are appropriate and reflect the maturity of our company. For example, to promote good governance and accountability at the highest level, the Board of Directors, on its own initiative, changed the term of service structure for directors from staggered three-year terms to one-year terms for every director. To promote ethical business practices, we have adopted a detailed Code of Business Conduct and Ethics, and we have training, policies and controls

TABLE OF CONTENTS

designed to prevent corruption in our business. We also have adopted policies supporting the protection of human rights and were an early company to take a public stance regarding Russia’s invasion of Ukraine by publicly announcing our suspension of business in Russia. Our stance for responsible business practices was acknowledged by the Yale School of Management, which listed Fortinet as one of the early companies receiving an “A” grade for halting engagement in Russia, distinguishing us from others in our industry.

CORPORATE GOVERNANCE

Human Capital Management

Our employees are the foundation of our innovation and cybersecurity leadership for the benefit of our customers. We understand there is a shortage of highly skilled employees for security companies like ours, and we believe that our success and competitive advantage depends largely on our ability to continue to attract and retain highly skilled employees with diverse backgrounds and experiences. We believe we offer fair, competitive compensation and benefits, and we encourage a culture of fairness and meritocracy. Our compensation programs for our employees include base pay, incentive compensation, opportunities for equity ownership where local statutes allow and employee benefits that promote well-being across different aspects of our employees’ lives, which may include health and welfare insurance, retirement benefits and paid time off.

As a global company, much of our success is rooted in the diversity of our teams and our commitment to diversity, equity and inclusion. Such commitment starts at the top, with a highly skilled and diverse board of directors. As of December 31, 2021, women represented one-third of the members of the Board of Directors, and approximately 56% of the members of the Board of Directors was from underrepresented communities as defined by California’s Assembly Bill 979. We value diversity at all levels and continue to focus on enhancing our diversity, equity and inclusion initiatives across our workforce.

We are also committed to community engagement and social responsibility with regards to our employees and beyond, and the Board of Directors has active oversight of such initiatives. Examples of our initiatives focused on our employees include our company matching program for employee charitable contributions and the free security training programs we offer to help with career development for our employees, in addition to the general public.

Our culture is defined by our commitment to ethics and integrity. We reinforce our ethical “tone at the top” through clear policies including our Code of Business Conduct and Ethics, regular compliance training for our employees, quarterly meetings of our cross-functional Ethics Committee, clear messaging from our executives, enforcement of company policies and oversight by the Board of Directors. In addition, our Chief Executive Officer regularly communicates the importance of Fortinet’s core values of openness, teamwork and innovation.

Early in the COVID-19 pandemic, our Chief Executive Officer committed to having no COVID-related layoffs, and, throughout the pandemic, not only have we kept that promise, we have continued hiring at a fast pace and have continued to help support our employees and their families through this challenging time. During the pandemic, we have taken a flexible approach to help our employees manage their work and personal responsibilities, with a focus on employee wellbeing, health and safety.

Corporate Governance Guidelines

We have adopted Corporate Governance Guidelines to establish the corporate governance policies which provide a structure within which the Board of Directors and management can effectively pursue Fortinet’s objectives for the benefit of our stockholders. The Corporate Governance Guidelines are available on Fortinet’s website at investor.fortinet.com/corporate-governance-0 .

Code of Business Conduct and Ethics

The Board of Directors sets high standards for Fortinet’s employees, officers and directors. Fortinet is committed to establishing an operating framework that exercises appropriate oversight of responsibilities at all levels throughout Fortinet and managing its affairs consistently with high principles of business ethics. Accordingly, Fortinet has adopted a Code of Business Conduct and Ethics, which is applicable to our and our subsidiaries’ directors, officers and employees.

The Code of Business Conduct and Ethics is available on Fortinet’s website at investor.fortinet.com/corporate-governance-0 . Fortinet will disclose on its website any amendments to, or waivers of, the Code of Business Conduct and Ethics that are required to be disclosed by the rules of the SEC or Nasdaq.

Majority Voting Standard for Director Elections and Director Resignation Policy

Our amended and restated bylaws provide for a majority voting standard for uncontested elections of directors and require that stockholder director nominations include a written statement as to whether the nominee intends to tender an irrevocable resignation upon such nominee’s election or re-election. The majority voting standard provides that, in uncontested director elections, a director nominee will be elected only if the number of votes cast FOR the nominee exceeds the number of votes cast AGAINST the nominee. In addition, our Corporate Governance Guidelines address, among other provisions, the “holdover” director situation under the Delaware General Corporation Law (pursuant to which a director remains on the board of directors until such director’s successor is elected and qualified), by requiring each incumbent nominee to submit an irrevocable contingent resignation letter prior to the annual meeting of stockholders in which such election is to take place. Such resignation becomes effective only upon (i) such nominee’s failure to receive the requisite number of votes for re-election at any future meeting at which such person would face re-election and (ii) the Board of Directors’ acceptance of such resignation. If the nominee does not receive the requisite number of votes for re-election, the Governance Committee will make a recommendation to the Board of Directors as to whether to accept or reject the resignation, or whether other action should be taken. The Board of Directors will act on the Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results.

Director Independence

The Board of Directors has determined that, with the exception of Messrs. Ken Xie and Michael Xie, who are employees of Fortinet, all of the current members of the Board of Directors and nominees for director are “independent directors” as that term is defined in Nasdaq’s listing standards.

Board Meetings and Committees

During fiscal 2021, the Board of Directors held six meetings. Each director attended at least 75% of the aggregate of all meetings of the Board of Directors and all meetings held by all committees of the Board of Directors on which such director served during the past fiscal year. The Board of Directors has four standing committees: the Audit Committee, the Human Resources Committee, the Governance Committee and the Social Responsibility Committee.

Audit Committee

The Audit Committee is currently comprised of Messrs.

Human Resources Committee Interlocks and Insider Participation

Mses. Ducourty and Sim and Mr. Goldman served as members of the Human Resources Committee during fiscal 2021. None of the members of the Human Resources Committee during fiscal 2021 is or has in the past served as an officer or employee of our company. None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on the Board of Directors or the Human Resources Committee during fiscal 2021.

Anti-Hedging and Anti-Pledging Policy

Our insider trading policy prohibits our directors, officers, employees and agents (such as consultants and independent contractors) from engaging in any form of hedging or similar transactions with respect to our securities, including those involving options, puts, calls or other derivative securities. Our directors, officers, employees and agents are also prohibited from pledging our securities as collateral for loans and from holding our securities in margin accounts.

Board Leadership Structure

Our Corporate Governance Guidelines provide the Board of Directors with flexibility to select the appropriate leadership structure depending on what the Board of Directors determines is in Fortinet’s best interests at a given time. In making leadership structure determinations, the Board of Directors considers many factors, including the specific needs of the business and what is in the best interests of our stockholders. A copy of our Corporate Governance Guidelines is available on our website at investor.fortinet.com/corporate-governance-0 .

Mr. Neukom currently serves as our Lead Independent Director and Mr. Ken Xie serves as our Chairman and Chief Executive Officer. In addition to the duties of all members of the Board of Directors, Mr. Neukom’s principal responsibilities as our Lead Independent Director are to: preside over executive

TABLE OF CONTENTS

sessions of the Board of Directors; review and comment on the agenda for meetings of the Board of Directors in consultation with the Chairman and Chief Executive Officer and other members of the Board of Directors; act as principal liaison between the independent directors and the Chairman and Chief Executive Officer on sensitive issues; raise issues with management on behalf of the independent directors when appropriate; and assess the quality, quantity and timeliness of the flow of information from management that is necessary for the independent directors to effectively and responsibly perform their duties.

The Board of Directors believes that the current leadership structure provides an appropriate balance between strong leadership from our Chairman and Chief Executive Officer and oversight by independent directors. In particular, this structure capitalizes on the expertise and experience of Messrs. Ken Xie and Neukom, as it permits Mr. Xie to serve as a bridge between the Board of Directors and management, helping both to act with a common purpose and providing critical leadership for carrying out our strategy and confronting challenges, while Mr. Neukom ensures independence of the Board of Directors from management and as Lead Independent Director can call and chair meetings of the independent directors separate and apart from the Chairman. The Board of Directors also believes that there may be other advantages to having a Lead Independent Director for matters such as communications and relations between the Board of Directors, the Chief Executive Officer and the other members of our senior management, and in assisting the Board of Directors in reaching consensus on particular strategies and policies. Messrs. Ken Xie and Michael Xie, as the only two management directors, do not participate in sessions of non-management directors, and non-management directors meet regularly in executive session without management.

Board of Directors’ Role in Risk Oversight

The Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and to enhance stockholder value. A fundamental part of risk management is not only understanding the most significant risks that Fortinet faces and what steps management is taking to manage those risks but also understanding what level of risk is appropriate for Fortinet. The involvement of the full Board of Directors in reviewing Fortinet’s business is an integral aspect of its assessment of management’s tolerance for risk and also its determination of what constitutes an appropriate level of risk for Fortinet.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board of Directors also have responsibility for risk management. Our Audit Committee reviews financial and other risk exposures, our internal controls over financial reporting, our disclosure controls and procedures, and our legal and regulatory compliance. Our Audit Committee also is responsible for oversight of risks related to data privacy and cybersecurity. Our Human Resources Committee evaluates our major compensation-related risk exposures and the steps management has taken to monitor or mitigate such exposures. In setting compensation, the Human Resources Committee strives to create incentives that encourage a reasonable level of risk-taking consistent with Fortinet’s business strategy and to encourage a focus on building long-term value at Fortinet. Our Human Resources Committee also oversees other areas of risk related to human resources, such as culture and ethics matters and DEI initiatives. Our Governance Committee has oversight on risks related to corporate governance matters, and oversees the evaluation of the performance of the Board of Directors. Our Social Responsibility Committee oversees risks related to our sustainability and corporate social responsibility and ESG approach, including long-term trends and impacts that may affect our business and main stakeholders. The Board of Directors also directly oversees certain strategic risks to Fortinet and other risk areas not delegated to one of its committees.

The risk oversight responsibility of our Board of Directors and its committees is supported by our management reporting processes. At periodic meetings of the Board of Directors and its committees and in other meetings and discussions, management reports to and seeks guidance from the Board of Directors and its committees with respect to the most significant risks that could affect our business, such as legal risks and financial, tax and audit related risks. In addition, management provides the Audit Committee periodic reports on Fortinet’s compliance programs and efforts, investment policy and practices. Our management reporting processes, including an enterprise risk assessment, are designed to provide our Board of Directors with visibility into the identification, assessment, and management of critical risks and into certain of

TABLE OF CONTENTS

management’s risk mitigation strategies. These areas of focus include competitive, economic, operational, financial (accounting, credit, investment, liquidity, compensation-related risk, and tax), human capital, legal, regulatory, cybersecurity and data privacy and reputational risks. Our Board of Directors reviews strategic and operational risk in the context of discussions, question-and-answer sessions, and reports from the management team at each regular meeting of the Board of Directors, and evaluates the risks inherent in significant transactions. Each director is invited to attend committee meetings, and the committees periodically provide the full Board of Directors reports on significant committee activities.

Cybersecurity Risk Oversight

Securing the information of our customers, team members, vendors and other third parties is of critical important to us. We have adopted physical, technological and administrative controls on data security, and have a defined procedure for data incident detection, containment, response and remediation. While everyone at our company plays a part in managing these risks, oversight responsibility is shared by the Board of Directors, the Audit Committee and management.

Our internal security team provides regular cybersecurity updates in the form of written reports and presentations to the Audit Committee. The Audit Committee regularly reviews metrics about cyber threat response preparedness, program maturity milestones, risk mitigation status and the current and emerging threat landscape. Additionally, we leverage the National Institute of Standards and Technology security framework to drive strategic direction and maturity improvement and engage third-party security experts for risk assessments and program enhancements. We also maintain information security risk insurance coverage.

Management Succession Planning

The Board of Directors recognizes that one of its most important duties is its oversight of succession planning for our Chief Executive Officer. The Board of Directors has delegated primary oversight responsibility for succession planning for our Chief Executive Officer to the Governance Committee, the Chairman of the Board of Directors and our Lead Independent Director. Our Chief Executive Officer is responsible for identifying, evaluating and selecting potential successors for our Chief Executive Officer’s direct reports. The Board of Directors regularly evaluates succession planning to ensure that we are well-positioned to continue to execute on our corporate strategy.

Oversight of Corporate Strategy

The Board of Directors actively oversees management’s establishment and execution of corporate strategy, including major business and organizational initiatives, annual budget and long-term strategic plans, capital allocation priorities, potential corporate development opportunities and risk management. At its regularly scheduled meetings and throughout the year, the Board of Directors receives information and formal updates from our management and actively engages with the senior leadership team with respect to our corporate strategy. Our directors’ diverse skill set and experience enhances the Board of Directors’ ability to support management in the evaluation and execution of our corporate strategy. The independent members of the Board of Directors also hold regularly scheduled executive sessions, during which corporate strategy is discussed.

Process for Recommending Candidates for Election to the Board of Directors

The Governance Committee is responsible for, among other things, determining the criteria for membership to the Board of Directors and recommending candidates for election to the Board of Directors. It is the policy of the Governance Committee to consider recommendations for candidates to the Board of Directors from stockholders. Stockholder recommendations for candidates to the Board of Directors must be directed in writing to Fortinet, Inc., 899 Kifer Road, Sunnyvale, California 94086, Attention: Corporate Secretary, and must include the candidate’s name, home and business contact information, detailed biographical data and qualifications, information regarding any relationships between the candidate and Fortinet within the last three years and evidence of the nominating person’s ownership of Fortinet’s common stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for membership on the Board of

TABLE OF CONTENTS

Directors, including issues of character, judgment, diversity, including whether the person is a current or former chief executive officer or chief financial officer of a public company or the head of a division of a large international organization, independence, expertise, corporate experience, length of service, other commitments and the like, personal references and an indication of the candidate’s willingness to serve. There are no differences in the manner by which the Governance Committee evaluates nominees for director based on whether the nominee is recommended by a stockholder or the Board of Directors.

The Governance Committee’s criteria and process for evaluating and identifying the candidates that it recommends to the full Board of Directors for selection as director nominees are as follows:

•

The Governance Committee evaluates the current composition and organization of the Board of Directors.

•

The Governance Committee reviews on at least an annual basis the desired qualifications and characteristics for membership on the Board of Directors.

•

The Governance Committee evaluates the performance of individual members of the Board of Directors eligible for re-election and selects, or recommends for the selection of the Board of Directors, the director nominees for election to the Board of Directors by our stockholders at the annual meeting of stockholders.

•

In its evaluation of director candidates, including the members of the Board of Directors eligible for re-election, the Governance Committee seeks to achieve a balance of knowledge, experience and capability on the Board of Directors and considers: (i) the current composition and organization of the Board of Directors and the needs of the Board of Directors and its committees; (ii) such factors as character, judgment, diversity, expertise, business experience, length of service, independence, other commitments and the like; and (iii) such other factors as the Governance Committee may consider appropriate. The Governance Committee considers diversity of skills, experience, gender and race, among other factors, in evaluating candidates for the Board of Directors.

•

While the Governance Committee has not established specific minimum qualifications for director candidates, the Governance Committee believes that candidates and nominees must reflect a Board of Directors that is comprised of directors who: (a) are predominantly independent; (b) are of high integrity; (c) have broad, business-related knowledge and experience at the policy-making level in business or technology, including their understanding of the networking security industry and Fortinet’s business in particular; (d) have qualifications that will increase overall effectiveness of the Board of Directors; and (e) meet other requirements as may be required by applicable rules, such as financial literacy or financial expertise with respect to Audit Committee members.

•

With regard to candidates who are properly recommended by stockholders or by other means, the Governance Committee will review the qualifications of any such candidate, which review may, in the Governance Committee’s discretion, include interviewing references for the candidate, direct interviews with the candidate, or other actions that the Governance Committee deems necessary or proper.

•

In evaluating and identifying candidates, the Governance Committee has the authority to retain and terminate any third-party search firm that is used to identify director candidates and has the authority to approve the fees and retention terms of any search firm.

•

The Governance Committee will apply these same principles when evaluating candidates for the Board of Directors who may be elected initially by the full Board of Directors to fill vacancies or add additional directors prior to the annual meeting of stockholders at which directors are elected.

•

After completing its review and evaluation of director candidates, the Governance Committee recommends to the full Board of Directors the director nominees.

Proxy Access

Our amended and restated bylaws provide a method for stockholders to place their nominees for director on our proxy ballot. Under our amended and restated bylaws, a stockholder, or a group of up to 20

TABLE OF CONTENTS

stockholders, owning at least 3% of our outstanding common stock continuously throughout the three-year period (i) through the date of the nomination notice or (ii) following date we implemented proxy access in our amended and restated bylaws, whichever is later, is entitled to nominate and include in our proxy materials director nominees constituting up to the lesser of two individuals or 20% of the number of members of the Board of Directors, subject to reduction in certain circumstances, and subject to the stockholders and the nominees satisfying the requirements specified in our amended and restated bylaws. Our obligation to include director nominees in its annual meeting proxy materials is also subject to certain exceptions as set forth in our amended and restated bylaws. Written notice of the nomination(s) must be submitted to our Corporate Secretary at our principal executive office no earlier than the 75 th day, and no later than the 45 th day, prior to the one-year anniversary of the date that we first sent our proxy materials or a notice of availability of proxy materials (whichever is earlier) for our immediately preceding annual meeting of stockholders, subject to certain exceptions as set forth in our amended and restated bylaws.

Attendance at Annual Meetings of Stockholders by the Board of Directors

Although Fortinet does not have a formal policy regarding attendance by members of the Board of Directors at Fortinet’s annual meeting of stockholders, Fortinet welcomes, but does not require, directors to attend. Ken Xie was the only director who attended Fortinet’s 2021 Annual Meeting of Stockholders.

Contacting the Board of Directors

Stockholders who wish to communicate with the members of the Board of Directors may do so by sending a letter to Fortinet’s Corporate Secretary, c/o Fortinet, Inc., 899 Kifer Road, Sunnyvale, California 94086, or by fax to (408) 235-7737. The Corporate Secretary reviews all incoming stockholder communications (except for mass mailings, product complaints or inquiries, job inquiries, business solicitations and patently offensive or otherwise inappropriate material) and, if appropriate, routes such communications to the appropriate member(s) of the Board of Directors, or if none is specified, to the Lead Independent Director.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This compensation discussion and analysis provides information about the 2021 compensation arrangements for each individual who served as one of our executive officers during 2021, who were as follows:

•

Ken Xie, our Chief Executive Officer;

•

Michael Xie, our President and Chief Technology Officer;

•

Keith Jensen, our Chief Financial Officer; and

•

John Whittle, our Executive Vice President of Corporate Development, Chief Legal Officer and Corporate Secretary.

We refer to these individuals as “named executive officers” in this proxy statement. Because we had no other executive officers during 2021, each one of our executive officers was a named executive officer in 2021.

This compensation discussion and analysis should be read together with the compensation tables and related disclosures that follow it. This discussion contains forward looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion.

Overview

We compete with many other technology companies in seeking to attract and retain highly skilled top talent. We also seek to keep our employees highly motivated. To meet these challenges, we designed our executive compensation program to attract, retain and motivate our named executive officers to enhance stockholder value by:

•

offering base pay and total compensation opportunities that are competitive compared with market and peer company data for the technology industry;

•

linking compensation to our operating, financial and stock price performance by making elements of each named executive officer’s compensation dependent on our overall company performance and the creation of stockholder value;

•

emphasizing equity pay and long-term incentives in order to incentivize contributions towards our growth and the creation of long-term value for our stockholders; and

•

ensuring fairness among our executive team by recognizing the contributions each named executive officer makes to our success.

Because our compensation program is designed to align our named executive officers’ compensation with our operating, financial and stock price performance, you should consider our executive compensation decisions in the context of these areas of our performance during 2021. Specifically:

•

Total revenue for 2021 was $3.34 billion, an increase of approximately 29% compared to $2.59 billion for 2020;

•

Total gross profit was $2.56 billion in 2021, an increase of 26% compared to $2.02 billion in 2020; and

•

Our stock price as of December 31, 2021 was $359.40 per share, an increase of approximately 142% compared to $148.53 as of December 31, 2020.

Role of the Human Resources Committee in Executive Compensation Decisions

The Human Resources Committee of the Board of Directors has overall responsibility for approving the compensation of our named executive officers. The Human Resources Committee also oversees our

TABLE OF CONTENTS

diversity, equity and inclusion initiatives and reviews with management the compensation disclosures required by the SEC. Members of the Human Resources Committee are appointed by the Board of Directors. See “ Corporate Governance — Board Meetings and Committees — Human Resources Committee ” for more detail about the responsibilities and procedures of the Human Resources Committee.

Role of Compensation Consultant

The Human Resources Committee relies on its independent compensation consultant to provide advice on matters relating to the compensation of our named executive officers and non-employee directors. For 2021 the Human Resources Committee engaged Compensia, Inc. (“Compensia”) in this capacity. A representative of Compensia generally attends meetings of the Human Resources Committee. In addition, Compensia provided competitive market assessments our executive and non-employee director compensation programs, reviewed the Compensation Discussion and Analysis section of our proxy statement and provided support on other matters as requested by the Human Resources Committee.

For 2021, the Human Resources Committee also engaged Compensia to provide and to report on the results of a competitive assessment of the compensation of our named executive officers, which is based on analysis of market and peer company compensation data. This assessment is one factor considered by the Human Resources Committee as discussed in more detail below under “— Determining the Amount of Elements of Executives’ Compensation in 2021 .” Compensia reports directly to the Human Resources Committee and provided no services to us other than the consulting services to the Human Resources Committee. Based on consideration of the various factors set forth in the rules of the SEC and Nasdaq listing standards, the Human Resources Committee does not believe that its relationship with Compensia and the work of Compensia on behalf of the Human Resources Committee has raised any conflict of interest.

Role of Executives in Executive Compensation Decisions

The Human Resources Committee generally seeks input from our Chief Executive Officer, Mr. Ken Xie, when discussing the performance of and compensation levels for our named executive officers other than for himself and Mr. Michael Xie. Neither Mr. Ken Xie nor any of our other named executive officers participates in deliberations relating to their own compensation, and Messrs. Ken Xie and Michael Xie do not participate in deliberations related to each other’s compensation.

Stockholder Advisory Vote on Named Executive Officer Compensation

Our stockholders will have the opportunity again at this year’s 2022 Annual Meeting to vote on our named executive officer compensation through the stockholder advisory vote (commonly known as a “say-on-pay” vote) included as Proposal Three in this proxy statement. At each of our past two annual meetings of stockholders starting with our first say-on-pay stockholder vote in 2011, over 91% of the stockholder votes cast have been cast in favor of our named executive officer compensation. The Human Resources Committee considers input from our stockholders and the outcome of our annual say-on-pay votes when making future executive compensation decisions and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, the Human Resources Committee will seek to understand and consider our stockholders’ concerns and will evaluate whether any actions are appropriate to address those concerns. Since the 2021 stockholder vote on executive compensation occurred after the Human Resources Committee had established all of the compensation elements for 2021, the Human Resources Committee could only take into consideration the 2021 stockholder vote in establishing executive compensation for 2022. We encourage you to review this “ Executive Compensation ” section, together with the compensation tables that follow, prior to casting your advisory vote on the “say-on-pay” proposal.

Elements of Our Compensation Program

The four key elements of our compensation program for our named executive officers are base pay, variable pay, equity-based awards and our benefits programs. As a total package, we design our compensation program to enable us to attract and retain talent who we believe will enhance Fortinet’s long-term value. The individual elements of Fortinet’s compensation program are designed to satisfy this larger goal in specific

TABLE OF CONTENTS

ways as described below. For a detailed discussion of the amounts awarded to our named executive officers during 2021, see “— Determining the Amount of Elements of Executives’ Compensation in 2021 ” below.

Base Pay . We establish base pay that is both reasonable and competitive in relation to the competitive market of similar companies in the technology industry. The Human Resources Committee monitors competitive base pay levels at least annually and makes adjustments to base pay as appropriate. In general, a named executive officer’s base pay level should reflect that individual’s overall sustained performance and contribution over time. The Human Resources Committee sets base pay to provide the ongoing reward for each named executive officer’s work and contribution and to be competitive in attracting or retaining the executive. Any increases in base pay are provided generally on an annual basis.

Variable Pay . Rewarding performance through cash variable pay is an important element of named executive officer compensation. We design our variable pay program to be both reasonable and competitive in relation to the market. Our senior management incentive bonus program is designed to motivate our named executive officers to achieve business goals and to align payouts with actual results. The variable pay incentives are based on a formulaic assessment of our financial performance and an assessment of each individual’s performance. A factor in this evaluation is our executive “peer review” process, in which our broader executive team reviews the performance of the other members of the team, including certain of the named executive officers, on a quarterly basis, and their confidential feedback is reviewed by the Human Resources Committee when considering individual variable pay incentives. We believe the executive peer review motivates executive officers to work together in a productive fashion. The Human Resources Committee has the discretion to increase or decrease a payout under our variable pay program at any time in the event that it determines that circumstances warrant adjustment.

Equity-Based Awards . The Human Resources Committee designs our equity-based awards to be both reasonable and competitive in relation to the market.

As described in more detail below, we design our equity-based awards to help retain talent over a period of time and to provide our named executive officers with a long-term reward that aligns their interests with those of our stockholders. The Human Resources Committee considers a number of factors when determining the size of equity awards, including competitive market data, named executive officer performance, the proposed award’s retention value, the value of unvested equity awards already held by the named executive officer and a review of the named executive officer’s overall compensation package, which takes into account our approach to base pay and variable pay. Initial equity awards granted upon hire are generally designed to attract experienced executives with established records of success and help retain them over the long term. Subsequent equity awards are designed to help retain and incentivize our named executive officers.

The Human Resources Committee approved awards of stock options and restricted stock units (“RSUs”) to our named executive officers in January 2021, which were effective in February 2021. In fiscal 2021, the Human Resources Committee granted stock options and RSUs, which represent a right to receive shares of our common stock upon vesting over time. The Human Resources Committee determined to grant stock options and RSUs based on an evaluation of the objectives of our compensation program and taking into consideration market practice among companies in our compensation peer group. The Human Resources Committee grants stock options and RSUs in order to: create a stronger and more visible link between executive pay and Fortinet’s stock price performance; further align our executives’ interests with those of our stockholders; to better incentivize and retain our senior executives; and maintain a long-term incentive program that is competitive with practices at peer companies. The Human Resources Committee considers stock options a strong pay-for-performance vehicle as the value of a stock option is limited to the excess of then-current stock price over the exercise price of the option. Stock options also support a long-term perspective as the grants to our named executive officers in fiscal 2021 vest over four years and can be exercised for up to seven years after grant.

Information on the vesting schedules for the awards of stock options and RSUs made to our named executive officers in 2021 can be found below in “— Determining the Amount of Elements of Executives’ Compensation in 2021 — Equity-Based Awards .” See “— Outstanding Equity Awards at 2021 Fiscal Year-End Table ” for additional information regarding the outstanding and unvested equity awards held by each named executive officer as of the end of fiscal 2021.

TABLE OF CONTENTS

Benefits Programs . We provide our named executive officers the following benefits: health and welfare benefits, including participation in our 401(k) retirement plan; group health insurance plans; and life, disability and accidental death insurance plans. Our named executive officers generally receive the same benefits as those provided to our other U.S. employees and do not receive any additional perquisites. We design our employee benefits programs to be both cost-effective and competitive in relation to the market as well as compliant with applicable laws and practices. We adjust our benefits programs as needed based upon regular monitoring of applicable laws and practices and the overall market.

Determining the Amount of Elements of Executives’ Compensation in 2021

Peer Group . In July 2020, with assistance from Compensia, the Human Resources Committee developed and approved a compensation peer group as a source of competitive market data for evaluating the compensation of our executive officers and to support pay decisions for 2021.

The peer group was comprised of security competitors, network infrastructure technology companies and other software companies focusing on data management, internet infrastructure and enterprise application software. In selecting peers, the Human Resources Committee also generally sought to include companies with annual revenue ranging from approximately $1.1 billion to $4.5 billion and a market capitalization generally ranging from $11 billion to $45 billion. The peer group approved in July 2020 included the 16 technology companies listed below:

	Akamai Technologies			Okta
	ANSYS			Palo Alto Networks
	Arista Networks			Splunk
	Cadence Design Systems			Synopsys
	Check Point Software Technologies			Twilio
	Citrix Systems			VeriSign
	CrowdStrike Holdings			Workday
	NetApp			Zscaler

For 2021, the Human Resources Committee removed Dropbox, F5 Networks, GoDaddy, Juniper Networks, PTC and SS&C Holdings from the peer group and added Okta, Twilio, Workday and Zscaler to the peer group.

Base Pay . As part of our annual performance review process and review of named executive officers’ compensation, early each year the Human Resources Committee assesses the performance of the named executive officers, considering factors such as company performance, department performance and individual performance, including the named executive officer’s expertise, position, past contributions to Fortinet and potential future contributions to Fortinet. Largely as a result of this assessment and taking into account reasonable annual base pay increase practices and Compensia’s data and analysis, the Human Resources Committee considered whether and how much to adjust the base pay of the named executive officers.

Taking into consideration performance and reasonable merit increases to position salary for our named executive officers generally between the 50 th and 65 th percentile of the competitive market, in January 2021, the Human Resources Committee kept the annual base pay of Mr. Ken Xie at $797,000, of Mr. Michael Xie at $445,000 and of Mr. Jensen at $490,000, and raised the annual base salary of Mr. Whittle by 3% to $442,000. After these increases, salary for our named executive officers was generally between the 50 th and 65 th percentile of the competitive market.

Equity-Based Awards . In granting stock options and RSUs to our named executive officers in 2021, the Human Resources Committee exercised its judgment and considered, among other things, the role and contribution of the named executive officer, the value of unvested stock options and RSUs already held by the executive and Compensia’s data and analysis.

In January 2021, the Human Resources Committee approved awards of stock options exercisable for up to 108,801 shares for Mr. Ken Xie, 43,713 shares for Mr. Michael Xie, 38,343 shares for Mr. Jensen and 24,411 shares for Mr. Whittle. Each of these stock options was granted in accordance with Fortinet’s Equity

TABLE OF CONTENTS

Award Grant Policy discussed in “— Timing of Equity Awards ” below, and vests over four years, with 25% vesting one year from February 22, 2019 and the remainder vesting monthly thereafter.

Also in January 2021, the Human Resources Committee approved awards of 36,267 RSUs for Mr. Ken Xie, 14,571 RSUs for Mr. Michael Xie, 12,781RSUs for Mr. Jensen and 8,137 RSUs for Mr. Whittle. Each of these RSUs was granted in accordance with Fortinet’s Equity Award Grant Policy discussed in “— Timing of Equity Awards ” below, and vests over four years, with 25% vesting one year from February 22, 2019 and the remainder vesting quarterly thereafter.

Variable Pay . We determine the executive’s actual level of variable compensation in accordance with the terms of the Senior Management Bonus Program (the “Bonus Program”) approved by the Human Resources Committee for the year. In developing the framework, we seek to set total cash compensation (i.e. base salary plus variable pay) to meet our goal of ensuring that our cash compensation levels are competitive and to enable us to retain and motivate our named executive officers.

In 2021, the Human Resources Committee based the Bonus Program funding on achievement of revenue and operating income targets, as set forth in more detail below, with 70% of the bonus pool funding based on revenue achievement and 30% based on operating income achievement. The Human Resources Committee weighted the Bonus Program funding more heavily toward achieving revenue over operating income because it believed that, at this stage, a continued focus on growing revenue would help drive our long-term success and result in greater opportunity for profit in the future and enhanced stockholder value. However, because we believe it is important for our executives to monitor expenses closely as well, the Human Resources Committee also based a portion of the bonus pool funding on our operating income performance. Operating income for purposes of the Bonus Program is not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”) but rather is defined as net income plus income taxes, stock-based compensation, interest income and foreign exchange currency gains or losses and other adjustments to GAAP income as defined in our non-GAAP definition for external reporting purposes.

For purposes of the Bonus Program, a minimum performance level (based on a percentage of the revenue and operating income target levels) had to be met before funding could occur. For 2021, threshold (i.e. the minimum) performance level was 90% of both the revenue target and the operating income target. Once the threshold performance level was attained, the funding of the bonus payments for our named executive officers was to increase on a graduated basis for each of the revenue portion and the operating income portion as follows:

Revenue Performance			Funding Amount
90% – 100%			40% funding for performance at 90% and 6% funding for every additional 1% of performance between 90% and 100%
100% – 140%			1% funding for every additional 1% of performance between 100% and 140%

Operating Income Performance			Funding Amount
90% – 100%			40% funding for performance at 90% and 6% funding for every additional 1% of performance between 90% and 100%
100% – 140%			1% funding for every additional 1% of performance between 100% and 140%

For example, for the revenue portion for our named executive officers:

•

At 90% achievement of the revenue target, the revenue portion of the Bonus Program would be funded at 40%;

•

At 95% achievement of the revenue target, the revenue portion of the Bonus Program would be funded at 70%;

•

At 100% achievement of the revenue target, the revenue portion of the Bonus Program would be funded at 100%; and

TABLE OF CONTENTS

•

At 140% achievement of the revenue target, the revenue portion of the Bonus Program would be funded at 140%.

Bonuses payments were calculated and awarded quarterly. Bonus payments were based on unaudited, preliminary revenue and operating income results. Adjustments based on actual revenue and operating income results may be made in subsequent quarters at the Human Resources Committee’s discretion. No bonuses are paid to our named executive officers under the Bonus Program if our financial results are below our guidance such that we pre-announce our financial results.

Individual target bonuses under the Bonus Program are expressed as a percentage of the named executive officer’s base salary for 100% goal achievement. During 2021, our Chief Executive Officer made recommendations for target bonuses to the Human Resources Committee for Messrs. Jensen and Whittle, taking into consideration company achievement versus the financial targets discussed below and peer group data. The Human Resources Committee in turn gave final approval after discussing the recommendations. The Human Resources Committee approved target bonuses for Messrs. Ken Xie and Michael Xie based upon the same criteria under the Bonus Program.

For 2021, the Human Resources Committee approved target bonuses of 120% of base salary for Mr. Ken Xie, 75% of base salary for Mr. Michael Xie, 80% of base salary for Mr. Jensen and 70% of base salary for Mr. Whittle. See “— 2021 Summary Compensation Table ” below.

As noted above, the Bonus Program was based on revenue and operating income performance targets set at the beginning of the year. The targets were set at levels determined to be challenging and requiring substantial effort on the part of senior management. For 2021, we achieved between 103% and 108% of our quarterly and annual revenue targets and we achieved between 111% and 114% of our quarterly and annual operating income targets. The Human Resources Committee approved bonus payments for our senior management for 2021 based on achievement of these corporate goals and the individual performance of certain of our named executive officers as evaluated pursuant to the “peer review” process described above. The following charts set forth both the target levels for our revenue and operating income performance, the revenue and operating income levels actually achieved, and the percentages of target revenue actually achieved.

Benefits Programs . In 2021, our named executive officers received the same employee benefits as our other U.S.-based employees and did not receive any additional perquisites. Additional details regarding our benefits programs can be found above in “— Elements of Our Compensation Program — Benefits Programs .”

Amended and Restated Change of Control Severance Agreements

Effective August 2019, we entered into an Amended and Restated Change of Control Severance Agreement with each of our named executive officers. In addition to extending the term of each named executive officer’s existing Change of Control Severance Agreement to August 7, 2024, the Amended and Restated Change of Control Severance Agreements also aligned the change of control terms for each of our named executive officers.

TABLE OF CONTENTS

These Amended and Restated Change of Control Severance Agreements provide for payments and benefits upon termination of their employment in specified circumstances. These arrangements (including potential payments and terms) are discussed in more detail in the “— Potential Payments Upon Termination or Change of Control ” section below. We believe that these agreements help us from a retention standpoint, and they are particularly necessary in an industry such as ours, where there has been market consolidation. We believe that entering into these agreements helps the named executive officers maintain continued focus and dedication to their assigned duties to maximize stockholder value. The terms of these agreements were determined after review by the Human Resources Committee of our retention goals for each named executive officer, as well as analysis of market data, similar agreements established by our peer group and applicable law.

Timing of Equity Awards

The Human Resources Committee approved grants of both stock options and RSUs to our named executive officers in January 2021. The Board of Directors and Human Resources Committee reserve the right, however, to grant stock options, RSUs, performance stock units (“PSUs”) or other equity awards at other times during the year. With respect to newly hired employees, our practice is typically to grant equity awards at the first quarterly meeting of the Human Resources Committee following such employee’s hire date.

Pursuant to our Equity Award Grant Policy, equity awards are granted effective as of the date that is the tenth trading day on Nasdaq following the date of our next quarterly earnings announcement following the meetings of the Human Resources Committee or the Board of Directors when such equity awards were approved.

Performance-Based Compensation Recovery Policy

The Human Resources Committee has adopted a compensation recovery policy that allows us to recover or “clawback” performance-based cash compensation from certain employees who participate in the Bonus Program in the event of a material restatement of our financial results. Under the policy, if the material restatement would result in any performance-based cash compensation paid under the Bonus Program during the three years preceding the restatement to have been lower had it been calculated based on such restated results, we may recover the amounts in excess of what would have been paid under the restatement from any participant who received such performance-based cash compensation and who is determined to have engaged in intentional or unlawful misconduct that materially contributed to the need for such restatement. The Board of Directors (or a committee designated by the Board of Directors) has the sole authority to enforce this policy, and it is limited by applicable law.

Effect of Accounting and Tax Treatment on Compensation Decisions

In the review and establishment of our compensation program, we consider the anticipated accounting and tax implications to us and our executives. In this regard, we have historically used stock options, RSUs and PSUs, and we reserve the right to use other forms of equity, as additional forms of equity incentives in response to changes in the accounting treatment of equity awards and taking into consideration potential impact on dilution and competitive practices. While the Human Resources Committee considers the applicable accounting and tax treatment, these factors alone are not determinative, and the Human Resources Committee also considers the cash and non-cash impact of the programs and whether a program is consistent with our overall compensation philosophy and objectives.

Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), generally disallows the deductibility by any publicly held corporation of individual compensation expenses in excess of $1 million paid to certain executive officers within a taxable year. The Tax Cuts and Jobs Act, which was signed into law in December 2017, limited or eliminated the “performance-based compensation” exception to the Section 162(m) deductibility limit, effective for tax years beginning after December 31, 2017. As a result, any compensation paid to such executive officers in excess of $1 million will be non-deductible unless such compensation was previously exempt and is payable pursuant to a written binding contract that was in effect on November 2, 2017. We believe it is likely that compensation income recognized upon the exercise of stock options granted prior to November 2, 2017 will continue to be tax deductible in future years. However,

TABLE OF CONTENTS

because the tax reform changes are complex and their effect is unsettled, we can offer no such assurance of deductibility. All other compensation paid after December 31, 2017 to such executive officers in excess of $1 million, including cash compensation, stock options, RSUs and PSUs awarded or modified after November 2, 2017, will be non-deductible. We expect that the Human Resources Committee will continue to seek to balance the cost and benefit of tax deductibility with our executive compensation goals designed to promote stockholder interests, retaining discretion to approve compensation that is non-deductible when it believes that such payments are appropriate to attract and retain executive talent. As a result, we expect that a significant portion of future cash and equity payments to our executive officers will not be tax deductible under Section 162(m).

Human Resources Committee Report

The Human Resources Committee oversees our compensation policies, plans and benefit programs. The Human Resources Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management. Based on such review and discussions, the Human Resources Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement.

Potential Payments Upon Termination or Change of Control

Termination or Change of Control Arrangements

On August 7, 2019, we entered into an Amended and Restated Change of Control Severance Agreement with each of our named executive officers, under which each named executive officer may receive certain payments and benefits upon certain terminations of employment, provided that the named executive officer has provided us with an executed release of claims and subject to non-solicitation and non-competition for a period of 12 months. The term of each named executive officer’s Amended and Restated Change of Control Severance Agreement expires on August 7, 2024.

Pursuant to each Amended and Restated Change of Control Agreement, if a named executive officer is terminated without Cause (as defined below) or if a named executive officer terminates the named executive officer’s employment with us for Good Reason (as defined below) prior to, or absent, a Change of Control (as defined below), or after 12 months following a Change of Control, the named executive officer will be entitled to: (i) a severance payment in an amount equal to 12 months of the named executive officer’s then-current base salary; (ii) acceleration of the unvested equity awards then held by the named executive officer that would have vested over the next 12 months; and (iii) 12 months of medical, dental and/or vision benefits for the named executive officer and/or the named executive officer’s eligible dependents.

Also pursuant to each Amended and Restated Change of Control Agreement, if a named executive officer is terminated without Cause or if a named executive officer terminates the named executive officer’s employment with us for Good Reason within 12 months following a Change of Control, the named executive officer will be entitled to: (i) a severance payment in an amount equal to 12 months of the named executive officer’s then-current base salary; (ii) acceleration of 100% of the unvested equity awards then held by the named executive officer; and (iii) 12 months of medical, dental and/or vision benefits for the named executive officer and/or the named executive officer’s eligible dependents.

In the event of acceleration of a named executive officer’s unvested equity awards, the awards will remain exercisable, to the extent applicable, following the termination for the period prescribed in the respective stock plan and agreement for each award. In the event any payment to a named executive officer

TABLE OF CONTENTS

is subject to the excise tax imposed by Section 4999 of the Code (as a result of a payment being classified as a “parachute payment” under Section 280G of the Code), the named executive officer will be entitled to receive such payment as would entitle the named executive officer to receive the greatest after-tax benefit of either the full payment or a lesser payment which would result in no portion of such severance benefits being subject to excise tax.

For the purpose of our Amended and Restated Change of Control Severance Agreements:

(i)

“Change of Control” generally means:

(a)

the acquisition by one person or group of persons of Fortinet securities representing 50% or more of total voting power at the time of acquisition;

(b)

a change in the composition of the Board of Directors occurring within a 12-month period, which results in fewer than a majority of the directors on the Board of Directors being incumbent directors;

(c)

the date of the consummation of a merger or consolidation between Fortinet and any other corporation that has been approved by our stockholders, other than a merger or consolidation that would result in our voting securities representing 50% or more of the total voting power immediately after such merger or consolidation, or if our stockholders approve a plan of Fortinet’s complete liquidation; or

(d)

a change in the ownership of a substantial portion of Fortinet’s assets, having a total gross fair market value equal to or more than 50% of the total fair market value of all of Fortinet’s assets immediately prior to such acquisition.

Notwithstanding the foregoing, a transaction that does not constitute a change of control event under Treasury Regulation 1.409A-3(i)(5)(v) or (vii) shall not be considered a Change of Control.

(ii)

“Cause” generally means:

(a)

an act of dishonesty by the named executive officer in connection with the named executive officer’s responsibilities as an employee that materially and adversely affects Fortinet;

(b)

the named executive officer’s conviction of, or plea of nolo contendere to, a felony or any crime involving fraud, embezzlement or any other act of moral turpitude;

(c)

the named executive officer’s gross misconduct that materially and adversely affects Fortinet’s reputation or business; or

(d)

the named executive officer’s continued intentional refusal to perform employment duties in a material fashion that materially and adversely affects Fortinet’s reputation or business, after the named executive officer has received a written demand of performance from Fortinet that specifically sets forth the factual basis for Fortinet’s belief that the named executive officer has not substantially performed the named executive officer’s duties and the named executive officer continues to refuse to cure such non-performance within thirty days after receiving such notice.

(iii)

“Good Reason” generally means the occurrence of one of more of the following events without the named executive officer’s express written consent:

(a)

a material diminution in the named executive officer’s position or responsibilities with Fortinet;

(b)

a material reduction in the base salary of the named executive officer;

(c)

a material change in the geographic location of the named executive officer of 25 miles or more;

(d)

any material breach by Fortinet of any material provision of the Change of Control Severance Agreement; or

TABLE OF CONTENTS

(e)

Fortinet’s failure to obtain the assumption of the Change of Control Severance Agreement by any successor to substantially all of Fortinet’s business and/or assets.

The named executive officer may not resign for Good Reason without first providing us with written notice of the acts or omissions constituting the grounds for “Good Reason” within 90 days of the initial existence of the grounds for Good Reason and a reasonable cure period of not less than 30 days following the date of such notice, and the named executive officer’s resignation of employment must occur no later than 30 days following the end of such 30-day cure period.

Estimated Payments upon Termination or Change in Control

The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of the named executive officers. Except where otherwise noted, payments and benefits are estimated assuming that the triggering event took place on the last business day of 2021, which was December 31, 2021, and the price per share of Fortinet’s common stock was the closing price on Nasdaq as of that date, which was $359.40 per share. There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, of if any other assumption used to estimate potential payments and benefits is not correct. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different.

(1)

A “Qualifying Termination” under the Change of Control Severance Agreement is an involuntary termination of employment without “Cause” or a voluntary resignation for “Good Reason,” in each case as defined above.

(2)

The severance amount related to base salary was determined based on base salaries in effect on December 31, 2021, the last business day of 2021.

(3)

The value is calculated by multiplying (i) the number of the named executive officer’s unvested shares that would have vested over the 12 months after December 31, 2021 by (ii) (a) the difference between $359.40 (the per share closing stock price on December 31, 2021) and the exercise price for stock options or (b) $359.40 for RSUs.

(4)

The value represents the total value for reimbursement for insurance premium expenses incurred for group health insurance continuation coverage under Title X of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, for a period of up to 12 months.

(5)

The value is calculated by multiplying (i) the number of the named executive officer’s total unvested shares by (ii) (a) the difference between $359.40 (the per share closing stock price on December 31, 2021) and the exercise price for stock options or (b) $359.40 for RSUs.

CEO Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation our Chief Executive Officer, Mr. Ken Xie (our “CEO”), and the annual total compensation of the median employee of our company, excluding our CEO. For 2021:

•

the annual total compensation of our median employee was $202,875;

TABLE OF CONTENTS

•

the annual total compensation of our CEO as disclosed in the 2021 Summary Compensation Table was $14,203,211; and

•

the ratio of the annual total compensation of our CEO to the median of the annual total compensation of our employees was 70 to 1. This ratio is a reasonable estimate calculated in a manner consistent with SEC rules.

For purposes of calculating the pay ratio for 2021, we elected to use as our median employee the same individual that we originally identified as our median employee for 2020 and 2019 because there was no significant change to our employee population or compensation arrangements that we reasonably believed would significantly impact our pay ratio disclosure.

For a description of our methodology for identifying the median employee, see “CEO Pay Ratio Disclosure” on page 51 of our definitive proxy statement filed with the SEC on April 30, 2019.

We then calculated the annual total compensation for this individual using the same methodology we use to calculate the amount reported for our CEO in the “Total” column of the 2021 Summary Compensation Table as set forth in this proxy statement.

Because SEC rules for identifying the median of the annual total compensation of all employees allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee population and compensation practices, the pay ratio reported by other companies may not be comparable to our pay ratio, as other companies have different employee populations and compensation practices and may have used different methodologies, exclusions, estimates and assumptions in calculating their pay ratios. As explained by the SEC when it adopted these rules, the rule was not designed to facilitate comparisons of pay ratios among different companies, even companies within the same industry, but rather to allow stockholders to better understand and assess each particular company’s compensation practices and pay ratio disclosures.

Standard Director Compensation Arrangements

Following a review by Compensia of our annual cash retainer policy and equity award grant policy for non-employee directors, in July 2021, the Human Resources Committee recommended, and the Board of Directors approved, various changes to our cash retainer policy and equity award grant policy for non-employee directors. In accordance with our annual cash retainer policy and equity award grant policy applicable to non-employee directors, each non-employee director is entitled to receive the following compensation for service on the Board of Directors:

•

an annual cash retainer for serving on the Board of Directors of $55,000, paid quarterly, in addition to the annual cash retainer for service on the committees of the Board of Directors as discussed below;

•

an annual cash retainer for serving as lead independent director of the Board of Directors of $35,000, paid quarterly;

•

an annual cash retainer for serving in a non-chairperson position on the (i) Audit Committee of $13,800, (ii) Human Resources Committee of $10,000, (iii) Governance Committee of $7,500 and (iv) Social Responsibility Committee of $7,500;

•

an annual cash retainer of (i) $32,500 for serving as the chairperson of the Audit Committee, (ii) $22,500 for serving as the chairperson of the Human Resources Committee, (iii) $15,000 for serving as the chairperson of the Governance Committee and (iv) $15,000 for serving as the chairperson of the Social Responsibility Committee;

•

after completion of each full year of service, an annual grant of a number of RSUs based on a total grant value equal to the peer 50 th percentile per Compensia’s director compensation analysis (which for 2021 was $245,000), vesting quarterly on the last day of each quarter and with the final installment vesting on the earlier of the last day of the second quarter and the day prior to the next annual meeting of stockholders; and

•

for newly appointed non-employee directors, an initial grant of a number of RSUs based on a total grant value equal to the then-applicable grant amount, pro-rated based on the projected days from the directors appointment date through the next annual meeting of stockholders, vesting in full on the day prior to the next annual meeting of stockholders.

TABLE OF CONTENTS

Prior to July 2021, the annual grant was a number of RSUs based on a total grant value of $250,000 and no cash retainer was paid for service on the Social Responsibility Committee, which was formed in January 2021. Otherwise, the compensation described above remained unchanged from the date of the 2021 Annual Meeting.

Non-Employee Director Stock Ownership Guidelines

We have adopted Stock Ownership Guidelines for our non-employee directors (the “Stock Ownership Guidelines”). The Stock Ownership Guidelines are designed to further align the interests of our non-employee directors with those of our stockholders by requiring each non-employee director to maintain a certain financial stake in our company.

Under the Stock Ownership Guidelines, each non-employee director is required to hold a number of shares of our common stock having a market value equal to at least five times such non-employee director’s annual base retainer (excluding fees paid for serving as the Lead Independent Director, Chairperson of the Board of Director or Chairperson or a member of a committee of the Board of Directors). Each non-employee director is required to acquire, and thereafter maintain, this minimum level of ownership by the end of the calendar year following such non-employee director’s fourth anniversary (or, if later, four years following the effective date of the Stock Ownership Guidelines).

Shares of our common stock that are beneficially owned by a non-employee director in the following forms are including in determining compliance with the Stock Ownership Guidelines: (i) shares owned by a non-employee director or their immediate family members residing in the same household; (ii) shares held in trust for the benefit of a non-employee director or their immediate family members residing in the same household; (iii) shares owned by a partnership, limited liability company or other entity to the extent of a non-employee director’s interest therein (or the interest therein of their immediate family members residing in the same household) and to the extent the non-employee director has or shares power to vote or dispose of the shares; (iv) vested and unexercised stock options; (v) vested RSUs and PSUs; (vi) other shares acquired through the 2009 Plan or other equity-based compensation plans; and (vii) shares owned in a 401(k) accounts.

Exceptions to the Stock Ownership Guidelines may be made for a particular non-employee director if the Human Resources Committee determines that the non-employee director would incur a hardship by complying with the Stock Ownership Guidelines. Failure to meet, or in unique circumstances, to show sustained progress toward meeting the Stock Ownership Guidelines may be a factor considered by the Human Resources Committee in determining future long-term incentive equity grants and/or appropriate levels of compensation.

Termination or Change of Control Arrangements

We have entered into change of control agreements with each of our non-employee directors. These agreements provide that, upon a Change of Control, 100% of the outstanding and unvested equity awards held by such directors will immediately vest in full.

“Change of Control” in our change of control agreements with our non-employee directors has the same meaning as used in our Change of Control Severance Agreements with the named executive officers. See “— Potential Payments Upon Termination or Change of Control — Termination or Change of Control Arrangements .”

Other Arrangements

While our non-employee directors are not typically paid or reimbursed for travel, lodging and related expenses associated with attending meetings of the Board of Directors or committees of the Board of Directors and for participating in activities related to service on the Board of Directors, we have from time-to-time paid or reimbursed our non-employee directors for reasonable expenses associated with attendance at meetings of the Board of Directors or committees of the Board of Directors.

The independent registered public accounting firm is responsible for auditing the financial statements. It is the responsibility of the Audit Committee to oversee these activities.

The Audit Committee has:

•

Reviewed and discussed the audited financial statements with Fortinet management and with Deloitte & Touche LLP, Fortinet’s independent registered public accounting firm;

•

Discussed with Deloitte & Touche LLP the matters required to be discussed by the Auditing Standard No. 1301 adopted by the Public Company Accounting Oversight Board regarding “Communication with Audit Committees”; and

Received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding Deloitte & Touche LLP’s communications with the Audit Committee concerning independence and has discussed with Deloitte & Touche LLP its independence.

Based upon these discussions and review, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in Fortinet’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 for filing with the United States Securities and Exchange Commission.

APPENDIX A

RECONCILIATION BETWEEN GAAP AND NON-GAAP FINANCIAL MEASURES

* * * * *

We have provided in this Proxy Statement information that has not been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). These non-GAAP financial and liquidity measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating our ongoing operational performance. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with peer companies, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures provided below.

Billings (non-GAAP). We define billings as revenue recognized in accordance with GAAP plus the change in deferred revenue from the beginning to the end of the period, less any deferred revenue balances acquired from business combination(s) and adjustment due to adoption of new accounting standard during the period. We consider billings to be a useful metric for management and investors because billings drive current and future revenue, which is an important indicator of the health and viability of our business. There are a number of limitations related to the use of billings instead of GAAP revenue. First, billings include amounts that have not yet been recognized as revenue and are impacted by the term of security and support agreements. Second, we may calculate billings in a manner that is different from peer companies that report similar financial measures. Management accounts for these limitations by providing specific information regarding GAAP revenue and evaluating billings together with GAAP revenue.

Free cash flow (non-GAAP). We define free cash flow as net cash provided by operating activities minus purchases of property and equipment and excluding any significant non-recurring items, such as proceeds from intellectual property matter. We believe free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after capital expenditures and net of proceeds from intellectual property matter, can be used for strategic opportunities, including repurchasing outstanding common stock, investing in our business, making strategic acquisitions and strengthening the balance sheet. A limitation of using free cash flow rather than the GAAP measures of cash provided by or used in operating activities, investing activities, and financing activities is that free cash flow does not represent the total increase or decrease in the cash and cash equivalents balance for the period because it excludes cash flows from significant non-recurring items, such as proceeds from intellectual property matter, investing activities other than capital expenditures and cash flows from financing activities. Management accounts for this limitation by providing information about our capital expenditures and other investing and financing activities on the face of the cash flow statement and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources” in our most recent Quarterly Report on Form 10-Q and Annual Report on Form 10-K and by presenting cash flows from investing and financing activities in our reconciliation of free cash flow. In addition, it is important to note that other companies, including companies in our industry, may not use free cash flow, may calculate free cash flow in a different manner than we do or may use other financial measures to evaluate their performance, all of which could reduce the usefulness of free cash flow as a comparative measure.
