PROXY STATEMENT

INFORMATION CONCERNING SOLICITATION AND VOTING

General

Our Board of Directors (our “Board”) is soliciting your proxy for the 2024 Annual Meeting of Stockholders to be held on Thursday, November 14, 2024, or at any postponements or adjournments of the meeting, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders. This proxy statement and related materials are first being made available to stockholders on or about September 27, 2024. References in this proxy statement to the “Company,” “we,” “our,” “us” and “Extreme Networks” are to Extreme Networks, Inc., and references to the “Annual Meeting” or the “2024 Annual Meeting” are to the 2024 Annual Meeting of Stockholders. When we refer to the Company’s fiscal year, we mean the annual period ending on June 30. This proxy statement covers our 2024 fiscal year, which began on July 1, 2023 and ended on June 30, 2024 (“fiscal 2024”).

Who May Vote, Record Date, Admission to Meeting

Only holders of record of the Company’s common stock at the close of business on September 17, 2024 (the “Record Date”) will be entitled to notice of, and to vote at, the meeting and any adjournment thereof. As of the Record Date, 132,046,287 shares of common stock were outstanding and entitled to vote. You are entitled to one vote for each share you hold.

You are entitled to attend the Annual Meeting if you were a stockholder of record or a beneficial owner of our common stock as of the Record Date, or if you hold a valid legal proxy for the Annual Meeting. To request a legal proxy, please follow the instructions at www.proxyvote.com or request a paper copy of the materials, which will contain the appropriate instructions.

If your shares are registered in the name of a broker, bank or other nominee, you may be asked to provide proof of beneficial ownership as of the Record Date, such as a brokerage account statement or voting instruction form provided by your record holder, or other similar evidence of ownership, as well as picture identification, for admission. If you wish to be able to vote virtually during the Annual Meeting, you must obtain a legal proxy from your broker, bank or other nominee and present it to the inspector of elections together with your ballot at the Annual Meeting. You may vote by mail by requesting a paper copy of the proxy materials, which will include a proxy card. To vote at the 2024 Annual Meeting, you may attend the 2024 Annual Meeting online.

Conduct of the Virtual Annual Meeting

To attend the 2024 Annual Meeting online, you must register before the meeting at www.proxyvote.com, or during the meeting at http://www.virtualshareholdermeeting.com/EXTR2024, with the 16-digit code printed in the box marked by the arrow on your proxy materials and follow the on-screen instructions.

Once you are logged in, you will be permitted to ask questions during the Annual Meeting. To ask a question, you will log in as a Stockholder using the 16-digit control number you received with your proxy materials. Questions about one of the matters in the agenda to be voted on by stockholders may be submitted via the web portal at or before the time the matters are before the Annual Meeting for consideration. We will answer such questions before the voting is closed. Following adjournment of the formal business of the Annual Meeting, we will address appropriate general questions from stockholders regarding the Company. Such questions may be submitted in the field provided in the web portal during the Annual Meeting.

You may vote at the Annual Meeting by following the instructions below under “Voting Instructions.”

If you encounter technical difficulties regarding the virtual Annual Meeting, please call the technical support number posted on the virtual meeting web page. If there are technical difficulties that make holding of the Annual Meeting unreasonably difficult or impossible, the Chair of the Board will make a determination to delay or reconvene the meeting, and will post a notification to stockholders at http://www.virtualshareholdermeeting.com/EXTR2024.

Broker Non-Votes

A broker non-vote occurs when a broker submits a proxy card with respect to shares held in a fiduciary capacity (typically referred to as being held in “street name”) but cannot vote on a particular matter because the broker has not received voting instructions from the beneficial owner. Under the rules that govern brokers who are voting with respect to such shares, brokers have the discretion to vote such shares on routine matters, but not on non-routine matters. Routine matters include the ratification of selection of auditors. Non-routine matters include the election of directors and amendments to or the adoption of stock plans or amendments to the certificate of incorporation.

Quorum

Our bylaws provide that a majority of the shares of our common stock issued and outstanding and entitled to vote at the meeting as of the Record Date must be represented at the meeting, either in person (virtually) or by proxy, to constitute a quorum for the transaction of business at the meeting, except to the extent that the presence of a larger number may be required by law. Your shares will be counted towards the quorum only if you submit a valid proxy, if your broker, banker or other nominee submits a proxy on your behalf, or if you vote in person (virtually) at the virtual Annual Meeting. Abstentions and broker non-votes will be counted as present for purposes of determining the presence of a quorum.

“Notice and Access” Model

The United States Securities and Exchange Commission’s (the “SEC”) proxy rules set forth how companies must provide proxy materials. These rules are often referred to as “notice and access.” Under the notice and access model, a company may select either of the following options for making proxy materials available to stockholders: (i) the full set delivery option; or (ii) the notice only option. A company may use a single method for all its stockholders or use the full set delivery option for some stockholders and the notice only option for others.

Under the full set delivery option, a company delivers all proxy materials to its stockholders by mail or, if a stockholder has previously agreed, electronically. In addition to delivering proxy materials to stockholders, the company must post all proxy materials on a publicly accessible web site (other than the SEC’s web site) and provide information to stockholders about how to access that web site and the hosted materials. Under the notice only option, instead of delivering its proxy materials to stockholders, the company delivers a “Notice of Internet Availability of Proxy Materials” that outlines (i) information regarding the date and time of the meeting of stockholders, as well as the items to be considered at the meeting; (ii) information regarding the web site where the proxy materials are posted; and (iii) various means by which a stockholder can request printed or emailed copies of the proxy materials.

In connection with our 2024 Annual Meeting, we have elected to use the notice only option. Accordingly, you should have received a notice by mail, unless you requested a full set of materials from prior mailings, instructing you how to access proxy materials at www.proxyvote.com and providing you with a control number you can use to vote your shares. You may request that the Company also deliver to you printed or emailed copies of the proxy materials.

All shares represented by a valid proxy, timely submitted to the Company, will be voted. Where a proxy specifies a stockholder’s choice with respect to any matter to be acted upon, the shares will be voted in accordance with that specification. If no choice is indicated on the proxy, the shares will be voted as recommended by the Board. If your shares are registered under your own name, you may revoke your proxy at any time before the Annual Meeting by (i) delivering to the Corporate Secretary at the Company’s headquarters either a written instrument revoking the proxy or a duly executed proxy with a later date, or (ii) attending the Annual Meeting and voting online. If you hold shares in street name, through a broker, bank or other nominee, you must contact the broker, bank or other nominee to revoke your proxy.

Vote Required to Adopt Proposals

The holder of each share of the Company’s common stock outstanding on the Record Date is entitled to one vote on each of the director nominees and one vote on each other matter. The director nominees who receive the highest number of “For” votes will be elected as directors. The advisory vote to approve our named officers’ compensation, the ratification of the appointment of Grant

Thornton LLP as our independent auditors for the fiscal year ending June 30, 2025, and the approval of the amendment and restatement of our 2013 Equity Incentive Plan, shall be determined by a majority of the votes cast affirmatively or negatively on the matter.

Effect of Abstentions and Broker Non-Votes

Votes withheld from any nominee, abstentions and “broker non-votes” (i.e., where a broker has not received voting instructions from the beneficial owner and for which the broker does not have discretionary power to vote on a particular matter) are counted as present for purposes of determining the presence of a quorum. Shares voting “withheld” have no effect on the election of directors. Abstentions have no effect on the advisory vote to approve our named executive officers’ compensation, the ratification of the appointment of Grant Thornton LLP as our independent auditors for the fiscal year ending June 30, 2025, or the approval of the amendment and restatement of our 2013 Equity Incentive Plan.

If you are a beneficial owner and hold your shares in “street name,” it is critical that you cast your vote if you want it to count in the election of directors and with respect to the other proposals included in this proxy. The rules governing brokers, banks and other nominees who are voting with respect to shares held in street name provide such nominees the discretion to vote on routine matters, but not on non-routine matters. Routine matters to be addressed at the Annual Meeting include the ratification of auditors. Non-routine matters include the election of directors, the advisory vote to approve our named executive officers’ compensation, and the approval of the amendment and restatement of our 2013 Equity Incentive Plan. Banks and brokers may not vote on these non-routine matters if you do not provide specific voting instructions. Accordingly, we encourage you to vote promptly, even if you plan to attend the Annual Meeting.

Voting Instructions

If you complete and submit your proxy card or the voting instruction card provided by your broker, bank or other nominee, the persons named as proxies will follow your instructions. If you do not direct how to vote on a proposal, the persons named as proxies will vote as the Board recommends on that proposal. Depending on how you hold your shares, you may vote in one of the following ways:

Stockholders of Record - You may vote by proxy, over the Internet or by telephone. Please follow the instructions provided in the Notice of Internet Availability of Proxy Materials or on the proxy card you received. You may also vote online at the Annual Meeting by attending the Annual Meeting online. To attend the Annual Meeting online, you must register online at www.proxyvote.com, or during the meeting at http://www.virtualshareholdermeeting.com/EXTR2024, with the 16-digit code printed in the box marked by the arrow on your proxy materials and follow the on-screen instructions.

Beneficial Stockholders - Your broker, bank or other nominee will provide you with a voting instruction card for your use in instructing it how to vote your shares. Since you are not the stockholder of record, you may not vote your shares online at the virtual Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other nominee, or by requesting one on www.proxyvote.com.

Votes submitted by telephone or via the Internet must be received by 11:59 p.m., Eastern Time, on November 13, 2024. Submitting your proxy by telephone or via the Internet will not affect your right to vote in person should you decide to attend the Annual Meeting.

If you are a stockholder of record, you may revoke your proxy and change your vote at any time before the polls close by returning a later-dated proxy card, by voting again by Internet or telephone as more fully detailed on your proxy card, or by delivering written instructions to the Corporate Secretary at the Company’s headquarters before the Annual Meeting. Attendance at the virtual Annual Meeting will not cause your previously voted proxy to be revoked unless you specifically request revocation or vote online at the virtual Annual Meeting. If your shares are held by a broker, bank or other nominee, you may change your vote by submitting new voting instructions to your broker, bank or other nominee in accordance with the nominees directions, or, if you have obtained a legal proxy from your broker, bank or other nominee giving you the right to vote your shares, by attending the Annual Meeting and voting online.

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted as follows:

If any other matter is properly presented at the Annual Meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares in his or her discretion.

Solicitation of Proxies

We will bear the entire cost of soliciting proxies. In addition to soliciting stockholders by mail, we will request banks, brokers and other intermediaries holding shares of our common stock beneficially owned by others to obtain proxies from the beneficial owners and will reimburse them for their reasonable expenses in so doing. We may use the services of our officers, directors and other employees to solicit proxies, personally or by telephone, without additional compensation. The Company has engaged Okapi Partners to assist in the solicitation of proxies and provide related advice, informational support, and outreach for a services fee and the reimbursement of customary disbursements that are not expected to exceed $26,000 in the aggregate.

Voting Results

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

ELECTION OF DIRECTORS

Vote Required and Board of Directors’ Recommendation

The persons receiving the highest number of votes represented by outstanding shares of common stock present or represented by proxy and entitled to vote at the 2024 Annual Meeting will be elected to the Board, provided a quorum is present. Votes “For”, votes to “Withhold” authority, and “broker non-votes” will each be counted as present for purposes of determining the presence of a quorum, but votes “withheld” and broker non-votes will have no effect on the outcome of the election. If you sign and return a proxy card without giving specific voting instructions as to the election of any director, your shares will be voted in favor of the nominees recommended by our Board.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE NOMINEES NAMED ABOVE.

Director Skills Matrix

The following summarizes key skills of our directors:

Arrangements Regarding Appointment of Directors

None of our directors are appointed pursuant to any arrangement with the Company. Pursuant to the offer letter between the Company and Mr. Meyercord respecting his employment, Mr. Meyercord must immediately resign as a director of the Board when his employment with the Company terminates.

CORPORATE GOVERNANCE

Our Board currently consists of seven directors. Our Board has reviewed the criteria for determining the independence of the Company’s directors under Nasdaq Rule 5605, Item 407(a) of Regulation S-K of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). It has affirmatively determined that, other than Mr. Meyercord, each member of our Board is independent under such criteria. The Board has determined that as of the date of this Proxy Statement the Board is comprised of a majority of directors who qualify under the rules adopted by the SEC and Nasdaq.

Directors to be elected at the 2024 Annual Meeting are to hold office until the 2025 annual meeting of stockholders and until their respective successors are elected and qualified.

Board and Leadership Structure

Our current leadership structure separates the roles of the Chief Executive Officer and the Chair of our Board. Mr. Shoemaker has served as the Independent Chair of our Board since February 2017. Our Corporate Governance Guidelines require that the Chair of our Board and Chief Executive Officer positions be separate; provided, that the Board, in its discretion, may appoint a non-independent director, who is not the CEO, as a Temporary Chair of the Board on an interim basis to serve during any period in which the Board is seeking an independent Chair of the Board. During any such interim period, the Board will appoint an independent director to serve as Lead Director.

Mr. Shoemaker’s duties as Independent Chair include:

Our Board appoints our President and Chief Executive Officer, Chief Financial Officer, Corporate Secretary and all executive officers. All executive officers serve at the discretion of our Board. Each of our executive officers devotes his or her full time to our affairs. Our directors devote time to our affairs as is necessary to discharge their duties. In addition, our Board has the authority to retain its own advisers, at the Company’s expense, to assist it in the discharge of its duties.

Board’s Role in Risk Oversight

Our Board has an active role in overseeing management of the risks we face. This role is one of informed oversight rather than direct management of risk. Our Board regularly reviews and consults with management on the Company’s strategic direction and the challenges and risks we face. Our Board also reviews and discusses with management on a quarterly basis its financial results and forecasts and regularly reviews cyber risk issues. The Audit Committee of our Board oversees management of the Company’s financial risks, and oversees and reviews our risk management policies, including the Company’s investment policies and anti-fraud program. The Compensation Committee of our Board oversees our management of risks relating to and arising from our compensation plans and arrangements. These committees periodically report on these matters to the full Board.

Management is tasked with the direct management and oversight of legal, financial and commercial compliance matters, which includes identification and mitigation of associated areas of risk. Our Chief Legal, Administrative and Sustainability Officer provides regular reports of legal risks and developments to the Audit Committee and to our full Board. Our Chief Financial Officer, Corporate Controller, Senior Vice President of Financial Planning & Analysis, and Senior Director of Internal Audit provide regular reports to the Audit Committee concerning financial, tax and audit related risks. In addition, the Audit Committee receives periodic reports from management on our compliance programs and efforts, our investment policies and practices, and the results of various internal audit projects. The Compensation Committee’s compensation consultant, together with our Senior Vice President of Human Resources and Chief Diversity & Inclusion Officer and other members of management, provides analysis of risks related to our compensation programs and practices to the Compensation Committee.

Meetings of the Board of Directors

Our Board held 11 meetings during the fiscal year ended June 30, 2024. No director attended fewer than 75 percent of the aggregate of the meetings of our Board held during the period for which he or she has been a director during fiscal 2024 and the meetings of the committees on which he or she served which were held during the periods in fiscal 2024 that he or she served on such committees.

Director Attendance at Annual Meetings

We encourage director attendance at the annual meetings of stockholders and we use reasonable efforts to schedule our annual meeting of stockholders at a time and date to maximize attendance by directors, taking into account our directors’ schedules. All of our current directors attended our 2023 annual meeting of stockholders.

Executive Sessions

The independent members of our Board meet regularly in executive session (without the presence or participation of non-independent directors), generally before or after a regularly scheduled Board meeting or at such other times as determined by our independent directors or our Chair. Executive sessions of the independent directors are chaired by our Chair. The executive sessions include discussions regarding guidance to be provided to the Chief Executive Officer and such other topics as the independent directors determine.

Committees of the Board of Directors

In fiscal 2024, our Board had the following three standing committees: Audit Committee; Compensation Committee; and Nom Gov Committee. Our Board has adopted a written charter for each of these committees, which are available on the Corporate Governance section of the Investor Relations page of our website at investor.ExtremeNetworks.com.

Fiscal 2024 Committee Membership

The members and Chairs of our standing committees as of June 30, 2024 were as follows:

Audit Committee - The current members of the Audit Committee are Ms. Holmgren and Messrs. Khanna and Kennedy. Mr. Khanna serves as Chair. Our Board has determined that each member of the Audit Committee (i) is independent as defined in applicable Nasdaq rules; (ii) meets the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act; (iii) has not participated in the preparation of financial statements of the Company or any current subsidiary of the Company at any time during the past three years; and (iv) is able to read and understand fundamental financial statements, including a company’s balance sheet, income statement and cash flow statement. Our Board further has determined that Mr. Khanna and Mr. Kennedy are “audit committee financial experts,” as defined by Item 407(d)(5) of Regulation S-K of the Exchange Act. Additionally, our Board has determined that Mr. Khanna and Mr. Kennedy have past employment experience in finance or accounting, requisite professional certification in accounting or other comparable experience or background that results in their financial sophistication, including being or having been a chief executive officer, chief financial officer or other senior officer with financial oversight responsibilities.

The Audit Committee reviews and reports to the Board on financial reports and financial information we disclose and our compliance with legal and regulatory requirements; reviews the qualifications, independence and performance, and approves the terms of engagement, of our independent auditors; and reviews the performance of the Company’s internal audit function. In this regard, the Audit Committee retains our independent auditors; approves the terms of engagement of the independent auditors for audit services and non-audit services; regularly communicates with the independent auditors, financial and senior management of the Company; and regularly reports to the Board. The Audit Committee is also responsible for establishing procedures for the receipt, retention and treatment of any complaints we receive regarding accounting or internal auditing controls, including anonymous

submission by our employees of concerns regarding accounting or auditing matters that may be submitted through our Whistleblower Hotline. In addition, the Audit Committee reviews our critical accounting policies and procedures and policies with respect to our financial accounting and internal controls. The Audit Committee also assists our Board in fulfilling its oversight responsibilities with respect to financial risks, including risk management in the areas of financial reporting, internal controls, investments and compliance with legal and regulatory requirements. The Audit Committee annually reviews and reassesses the adequacy of its Audit Committee Charter. The Audit Committee held eight meetings during fiscal 2024.

Compensation Committee - The current members of the Compensation Committee are Ms. Holmgren and Messrs. Carinalli, Kennedy, and Shoemaker. Mr. Carinalli serves as Chair. All members of the Compensation Committee are independent for purposes of the Nasdaq Marketplace Rules, and are “non-employee directors” for purposes of Rule 16b-3 under the Exchange Act and “outside directors” for purposes of Section 162(m) of the Internal Revenue Code. The Compensation Committee is responsible for discharging our Board’s responsibilities relating to compensation and benefits of our executive officers and evaluates and reports to our Board on matters concerning management performance, officer compensation and benefits plans and programs. In carrying out its responsibilities, the Compensation Committee reviews all components of executive officer compensation for consistency with our compensation philosophy. The Compensation Committee also administers our cash compensation plans, significant employee health and welfare and other benefit plans, and equity-based incentive plans. The Compensation Committee assists our Board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. Our President and Chief Executive Officer and our Senior Vice President of Human Resources and Chief Diversity & Inclusion Officer assist the Compensation Committee in its deliberations with respect to the compensation of our executive officers, provided, however, neither individual participates in the Compensation Committee’s deliberations or voting regarding his or her own compensation. In connection with the Company’s annual compensation review, each executive officer discusses his or her individual performance with our Chief Executive Officer, who addresses such performance with the Compensation Committee, and the Chief Executive Officer discusses his individual performance directly with the Compensation Committee. The Compensation Committee annually reviews and reassesses the adequacy of its Compensation Committee Charter. The Compensation Committee held nine meetings during fiscal 2024.

As permitted by its Charter, and subject to the provisions of Section 152 of the Delaware General Corporation Law, the Compensation Committee delegated to management the ability to award time-based restricted stock units (“RSUs”) under the Company’s 2013 Equity Incentive Plan to employees of the Company at the level of Vice President and below and for refresh grants within permitted ranges for Senior Vice Presidents. The delegation provided for limitations on the number of shares covered by the individual and aggregate awards, vesting over three years, and quarterly reporting to the Compensation Committee. The Company’s Chief Executive Officer or two of the Chief Financial Officer, Chief Legal, Administrative & Sustainability Officer and/or SVP of Human Resources and Chief Diversity & Inclusion Officer presently approve such awards, before the effective date of grant.

The Compensation Committee may retain, at the Company’s expense, one or more independent compensation consultants. As described under the heading “Executive Compensation and Other Matters—Compensation Discussion and Analysis,” the Compensation Committee was advised by Compensia, Inc., a national compensation consulting firm, with respect to various compensation matters during fiscal 2024. Compensia has served as the Compensation Committee’s compensation consultant since fiscal year 2013. The Compensation Committee has reviewed and is satisfied with the qualifications, performance and independence of Compensia. Compensia provides no services to the Company other than services for the Compensation Committee.

For more information about the Compensation Committee’s role and practices regarding executive compensation, see the discussion below under the heading “Executive Compensation and Other Matters.”

Nom Gov Committee - The Nom Gov Committee of the Board updated its charter and name to the Nominating, Governance and Environmental & Social Responsibility Committee effective May 17, 2023 to reflect the Company’s maturing environmental, social and governance focus. The current members of the Nom Gov Committee are Messrs. Shoemaker and Carinalli and Mses. Burton and Holmgren. Mr. Shoemaker serves as Chair. Each member of the Nom Gov Committee is independent. The Nom Gov Committee develops and recommends to the Board criteria for selecting qualified director candidates; identifies, reviews, and evaluates candidates to serve on our Board; considers committee member qualifications, appointment, and removal; recommends corporate governance principles, codes of conduct and compliance mechanisms applicable to us, including our Corporate Governance Guidelines; reviews, assesses and oversees matters related to corporate social responsibility, including diversity and inclusion goals, environmental matters, and philanthropic initiatives; assists our Board in its annual reviews of the performance of our Board, each committee of the Board, and management; and assists the Board in the administration of our Amended and Restated Tax Benefit Preservation Plan. The Nom Gov Committee assists our Board in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, membership and structure, succession planning for our directors and executive officers,

and corporate governance. The Nom Gov Committee periodically reviews and reassesses the adequacy of its Nom Gov Committee Charter. The Nom Gov Committee held four meetings during fiscal 2024.

Compensation Committee Interlocks and Insider Participation

None of our executive officers has served on the board of directors or compensation committee of any other entity that has, or has had, one of whose executive officers who served as a member of our Board or Compensation Committee during fiscal 2024. No member of the Compensation Committee was, during fiscal 2024 or any prior period, an officer or employee of the Company.

Director Nominations

Director Qualifications - In fulfilling its responsibilities, the Nom Gov Committee considers numerous factors in reviewing possible candidates for nomination as director, including:

The Nom Gov Committee considers many factors, including character, judgment, independence, age, education, expertise, diversity of experience, length of service, other commitments and ability to serve on committees of our Board, in evaluating potential candidates. It also considers individual attributes that contribute to board heterogeneity, including race, gender, and national origin. The Nom Gov Committee does not assign any particular weighting or priority to any of these factors or attributes.

There are no stated minimum criteria for director nominees, although the factors and attributes discussed above will play a material role in the recommendation of a candidate by the Nom Gov Committee. The Nom Gov Committee also believes it to be appropriate for one or more key members of management to participate as members of our Board.

Identifying and Evaluating Candidates for Nomination as Director - The Nom Gov Committee annually evaluates the current members of our Board who are willing to continue in service to determine whether to recommend to the full Board that these directors be submitted to the stockholders for re-election.

Candidates for nomination as director come to the attention of the Nom Gov Committee from time to time through incumbent directors, management, stockholders or third parties. These candidates may be considered at meetings of the Nom Gov Committee at any point during the year. Additionally, the Nom Gov Committee may poll directors and management for suggestions or conduct research to identify possible candidates if it believes that our Board requires additional members or nominees, or should add additional skills or experience. The Nom Gov Committee may engage a third-party search firm to assist in identifying qualified candidates, as it deems appropriate.

The Nom Gov Committee will consider candidates for directors proposed by its stockholders. To be evaluated in connection with the Nom Gov Committee’s established procedures for evaluating potential director nominees, any recommendation for director nominee submitted by a stockholder must be sent in writing to the Corporate Secretary at our corporate headquarters and must be received at our principal executive offices not earlier than the close of business 120 days prior to the one-year anniversary of the

preceding year’s annual meeting and not later than the close of business 90 days prior to such one-year anniversary, except that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be delivered, or mailed and received, not later than the 90th day prior to such annual meeting or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting is first made. For purposes of the foregoing, “public disclosure” shall mean disclosure in a press release reported by a national news service or in a document publicly filed or furnished by us with the SEC. The recommendation for director nominee submitted by a stockholder must contain the information required by our bylaws. You may contact our Corporate Secretary at our principal executive offices for a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates. In addition to satisfying the foregoing requirements under our bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our Board’s nominees must provide notice that sets forth the information required by Rule 14a-19. Candidates recommended by our stockholders will be evaluated against the same factors as are applicable to candidates proposed by directors or management.

All directors and director nominees must submit a completed directors’ and officers’ questionnaire as part of the nominating process. The evaluation process may also include interviews and additional background and reference checks for non-incumbent nominees, at the discretion of the Nom Gov Committee.

Board Diversity Matrix

The members of our board of directors have provided the diversity information below. Each of the categories listed in the table below has the meaning as it is used in Nasdaq Rule 5605(f).

Our directors have a long history of supporting women’s opportunities and ethnic diversity throughout their careers. Some are involved with programs and groups supporting international and diverse students from preschool to college. Our female directors have participated in events with our Women in Networking Alliance employee resource group. The Company’s management regularly reports to the Nom Gov Committee of the Board on the Company’s progress toward gender and diversity goals.

Board Member Resignation Policy

In the event one or more incumbent directors fails to receive the affirmative vote of a majority of the votes cast at an election that is not a contested election, that director shall promptly tender his or her irrevocable resignation to the Board. The Nom Gov Committee shall recommend to the Board whether to accept or reject the resignation of such incumbent director or whether other action should be taken. The Board shall act on the resignation, taking into account the recommendation of the Nom Gov Committee, and within ninety (90) days after the date of certification of the election results, the Board shall disclose its decision and the rationale regarding whether to accept the resignation (or the reasons for rejecting the resignation, if applicable) in a press release, a filing with

the SEC or by other public announcement. The director whose resignation is under consideration may not participate in any deliberation or vote of the Nom Gov Committee or the Board regarding his or her resignation. The Nom Gov Committee and the Board may consider any factors and other information they deem appropriate and relevant in deciding whether to accept a director’s resignation. If an incumbent director fails to receive the required vote for re-election in an election that is not a contested election and such director’s resignation is not accepted by the Board, such director will continue to serve until his or her successor is duly elected and qualified or until his or her death, resignation or removal. If such director’s resignation is accepted by the Board, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board may fill any resulting vacancy pursuant to the terms of the Company’s bylaws.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our executive officers, directors and persons who beneficially own more than 10 percent of our common stock to file initial reports of beneficial ownership and reports of changes in beneficial ownership with the SEC. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such person. Based solely on our review of the forms furnished to us and written representations from certain reporting persons, we believe that all filing requirements applicable to our executive officers, directors and persons who beneficially own more than 10 percent of our common stock were complied with in the fiscal year ended June 30, 2024.

Communications with Directors

The Board values the input and insights of the Company’s stockholders and believes that effective communication between the Board and stockholders strengthens the Board’s ability to effectively carry out its oversight function.

Stockholders of the Company may communicate directly with the independent members of the Board, including the Chair of the Board, about corporate governance, corporate strategy, Board-related matters or other substantive matters that the Company’s Corporate Secretary and Chair of the Board consider to be important for the directors to know, by addressing any communications to the intended recipient by name or position in care of:

Chair of the Board (or individually named director(s))

c/o Corporate Secretary

Extreme Networks, Inc.

2121 RDU Center Drive, Suite 300

Morrisville, North Carolina 27560

All communications, including stockholders recommendations of director candidates, must be accompanied by the following information:

The Corporate Secretary will initially receive all stockholder communications and will review the communications for compliance with this policy. The Corporate Secretary may consult with the Chair of the Board and legal counsel when determining whether a communication is appropriate for delivery.

The Corporate Secretary or his or her designee will send an acknowledgment of receipt to each stockholder who submits a communication. The Corporate Secretary may also communicate with the stockholder for any clarification deemed necessary, and may handle a communication directly where appropriate.

Communications deemed to comply with this policy and to be appropriate for delivery will be delivered to the directors as soon as practicable, and in any case, on a periodic basis, generally in advance of each regularly scheduled meeting of the Board. Concerns relating to accounting, internal accounting controls, auditing matters or questionable financial practices will be handled in accordance with the procedures established by the Audit Committee with respect to such matters.

The following types of communications are considered inappropriate for delivery to the directors, and will not be forwarded to them: (i) communications regarding individual grievances or other interests that are personal to the party submitting the

communication; (ii) communications regarding ordinary business operations or commercial matters not related to the stockholders' stock ownership; or (iii) communications that contain offensive, obscene, abusive, threatening, or otherwise inappropriate content, or that create safety or security concerns. The Corporate Secretary will review communications for compliance with this policy. The Corporate Secretary may consult with the Chair and legal counsel when determining whether a communication is appropriate for delivery.

Stockholders who wish to recommend individuals to the Nom Gov Committee for consideration as potential director candidates may, in accordance with relevant provisions of the Company’s Bylaws, submit the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nom Gov Committee, c/o Corporate Secretary, at the address listed above. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nom Gov Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

The Board reserves the right to respond to or otherwise communicate with stockholders, and determine the means of such communication, in its absolute discretion.

This policy for stockholder communications with the Board does not apply to (a) communications to independent members of the Board from other members of the Board or officers of the Company who are stockholders, or (b) stockholder proposals submitted pursuant to Rule 14a-8 under the Securities and Exchange Act of 1934. Requests for investor relations materials shall be directed to our Vice President of Corporate Development & Investor Relations at (919) 595-4196.

Code of Ethics and Corporate Governance Materials

Our Board has adopted charters for its Audit, Compensation, and Nom Gov Committees, which are available on the Corporate Governance section of our Investor Relations page of our website at investor.ExtremeNetworks.com. Our Board has also adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers and directors. The Code of Business Conduct and Ethics can also be found on our website on the Corporate Governance section of our Investor Relations page of our website at investor.ExtremeNetworks.com. We intend to satisfy the disclosure requirements under the Exchange Act regarding an amendment to or waiver from a provision of our Code of Business Conduct and Ethics by posting such information on our website.

Additionally, our Insider Trading Program, which is reasonably designed to promote compliance with insider trading laws, rules and regulations, including those imposed by the SEC and Nasdaq, (1) governs the purchase, sale and/or other disposition of the Company’s securities by directors, officers and employees of the Company, (2) prohibits our directors and certain employees, including all of our executive officers, from trading during quarterly blackout periods and contains other restrictions on trading activities designed to avoid circumstances where Company insiders may be deemed to have traded on material nonpublic information, and (3) prohibits our directors, officers and employees from engaging in short sales of our securities, entering into transactions in publicly traded options, puts, calls or other derivative securities, hedging transactions with respect to our securities, and pledging shares of our securities in margin accounts. Our Insider Trading Program also requires that our directors and certain restricted employees, including all of our executive officers, pre-clear any proposed open market transactions. A copy of our Insider Trading Program is attached as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended June 30, 2024 filed with the SEC on August 16, 2024.

Environmental, Social and Governance

Since 2020, when our Board amended the charter of our Nom Gov Committee to include social responsibility within the committee’s mandate, and re-named the committee as the Nom Gov Committee, the Company has been striving to appropriately incorporate social responsibility into our business strategy. We published our inaugural Corporate Responsibility (“CR”) Report in November 2020 and have published annual reports each subsequent year. We expect to publish an updated report in late September or early October 2024.

In fiscal 2024, we updated our environmental, social and governance materiality assessment, and re-aligned our areas of emphasis in conjunction with that materiality assessment. the definition of "materiality" used for the purposes of this assessment is broader and different from the definition used for the purposes of our required securities reporting. Our CR model can be divided into four categories – Planet, Product, People, and Governance.

To find out more about our corporate social responsibility and find links to our Corporate Responsibility Report, Corporate Social Responsibility Policy, Conflict Minerals Policy, Code of Conduct, Supplier Code of Conduct, and our EEO-1 report, please visit the Corporate Responsibility section of our website at https://www.extremenetworks.com/company/csr/. Our Corporate Responsibility Report for fiscal 2024 will be published on this page as well.

Although we reference our CR Report, CSR Policy, and the Corporate Responsibility section of our website in this proxy statement, none of these materials nor any other materials on our corporate website are incorporated by reference into this proxy statement or any filing of the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. While matters discussed in such Corporate Responsibility, CSR, and website materials, as well as this section of the proxy statement may be significant, any significance should not be read as necessarily rising to the level of materiality used for the purposes of our compliance with the U.S. federal securities laws, even where we use the word “material” or “materiality” in such materials.

DIRECTOR COMPENSATION

We maintain a non-employee director compensation program, pursuant to which cash fees and equity awards are paid to our non-employee directors in exchange for their service on our Board and its committees. For fiscal 2024, the compensation paid to our non-employee directors was as set forth below. Mr. Meyercord, who serves as our President and Chief Executive Officer, does not receive any additional compensation for his service on our Board.

Cash Compensation

Our non-employee directors are very actively engaged in oversight of corporate governance. Each non-employee director attends and actively prepares for and participates in all committee meetings, regardless of his or her committee membership. The Board and Compensation Committee take this, as well as the total cost of the Company's director compensation program, into consideration in determining Board compensation. During fiscal 2024, each non-employee director earned (a) $110,000 in cash compensation annually for Board service; and (b) the applicable compensation set forth below for serving either as a chair or as a member of one or more of the committees of our Board. Fees payable to directors who join the Board during the fiscal year, or who change Board assignments, are prorated to reflect the period of service. Each director further received reimbursement of expenses related to attendance of meetings of our Board and its committees, but no separate meeting fees are paid.

Fees for Fiscal Year 2024:

The amounts set forth above are unchanged from the 2023 program.

Equity Compensation

On the date of each annual meeting of our stockholders, each non-employee director continuing service with the Company after the meeting is granted an annual award of RSUs. The number of RSUs for fiscal year 2024 was determined by dividing $215,000 by the price of the Company’s common stock at the close of business on the Nasdaq Global Select Market on the date of the annual meeting, rounded down to the nearest whole RSU. RSU grants provided to directors who join the Board after the annual meeting of our stockholders are prorated to reflect the period of service. Each RSU represents the right to receive one share of our common stock upon vesting and settlement. On the date of the annual meeting of stockholders of the Company held on November 8, 2023, each non-employee director was granted 12,975 RSUs, which will vest upon the earliest of the one-year anniversary of the grant date or the next annual meeting, or a change in control of our Company, in each case, subject to the director’s continued service with the Company through such date.

Changes for Fiscal 2025

The Compensation Committee periodically reviews the director compensation program with Compensia, its compensation consultant. The Compensation Committee reviewed the total compensation package for directors in June 2024, following consultation with Compensia and reviewing data from Extreme’s peer group, and decided to increase the amount of the annual fee paid to the Chair from $70,000 annually to $100,000 annually, with no further changes to the director compensation program for fiscal 2025.

Stock Ownership Guidelines

The Compensation Committee requires non-employee directors to own shares, not including unearned appreciation or performance awards, with a value equal to at least five times (5X) the Company’s annual Board service retainer. Unearned appreciation

or performance awards are not considered when determining whether the ownership guidelines have been met. Each non-employee director has five years from his or her respective date of appointment or date of increase in ownership guidelines to attain the minimum ownership level. All of our non-employee directors have met the minimum requirements of the share ownership guidelines.

2024 Director Compensation

The compensation information for our non-employee directors who served during fiscal 2024 is set forth below:

PROPOSAL TWO:

ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

Background

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and as required under Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on an advisory non-binding basis, the compensation of our named executive officers (“NEOs”) as disclosed in this proxy statement in accordance with SEC rules. This is frequently referred to as a “Say on Pay” vote. This vote is intended to address the overall compensation of the Company’s NEOs and the philosophy, policies and practices described in this proxy statement with respect to their compensation, and not any specific item of compensation.

The Compensation Committee believes that our 2024 executive compensation program has been appropriately designed to advance stockholder interests through effective performance-based incentives with multi-year retention features. The last stockholder advisory vote on executive compensation was held in November 2023, and approximately 96 percent of votes cast were voted in favor of the Company’s compensation for its NEOs.

As described in further detail under the heading “Compensation Discussion and Analysis,” our executive compensation philosophy is designed to attract high quality candidates for senior leadership positions, to retain these employees, and to establish a total compensation program that motivates and rewards individual and team performance in a highly competitive industry. Our compensation programs are designed to align our executive officers’ performance with our goals and to create stockholder value.

We are asking our stockholders to indicate their support for our compensation arrangements with our NEOs as described in this proxy statement.

Vote Required and Board of Directors’ Recommendation

Approval of this proposal requires the affirmative vote of a majority of the votes cast for or against the proposal at the Annual Meeting, as well as the presence of a quorum representing a majority of the shares of our common stock entitled to vote at the Annual Meeting, present in person or represented by proxy. Abstentions and broker non-votes will each be counted as present for purposes of determining a quorum but will not have any effect on the outcome of the vote on this proposal.

This “Say on Pay” vote is advisory, and therefore is not binding on us, the Compensation Committee or our Board. However, our Board and our Compensation Committee value the opinions of our stockholders in their vote on this proposal and will consider the outcome of this vote when making future decisions regarding the compensation of our NEOs. We currently expect to conduct the next advisory vote on executive compensation at our 2025 annual meeting of stockholders.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL THREE:

RATIFY THE APPOINTMENT OF INDEPENDENT AUDITORS FOR THE FISCAL YEAR ENDING JUNE 30, 2025

The Audit Committee has appointed Grant Thornton LLP (“GT”) as our independent registered public accounting firm for our fiscal year ending June 30, 2025. GT has served as the Company’s independent registered public accounting firm since September 2021. A representative of GT is expected to be present at the 2024 annual meeting, will have an opportunity to make a statement if desired and will be available to respond to appropriate questions.

During our fiscal years ended June 30, 2024 and June 30, 2023, neither we nor anyone acting on our behalf has consulted with GT, regarding either: (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us that GT concluded was an important factor considered by us in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).

Audit Committee Pre-Approval Policies

Representatives of our independent auditors normally attend most meetings of the Audit Committee. The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by our independent auditors. These services may include audit services, audit-related services, tax services and other services. Any pre-approval is detailed as to the particular service or category of services. Our independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by our independent auditors in accordance with this pre-approval policy. In addition, the Audit Committee Charter provides that the Audit Committee may delegate to one or more members of the Audit Committee the authority to grant pre-approvals of permitted non-audit services that would otherwise be required to be pre-approved by the Audit Committee. Any pre-approvals granted under such delegation of authority are to be reported to the Audit Committee at the next regularly scheduled meeting. The Audit Committee has delegated authority to the Chair of the Audit Committee to pre-approve fees up to $250,000 for permitted audit and non-audit services to be provided to the Company by its independent auditors. For fiscal 2023 and 2024, all fees paid to our independent auditors were pre-approved in accordance with our pre-approval policy.

The Audit Committee, on an annual basis, reviews the services performed by the independent registered public accounting firm, and reviews and approves the fees charged by the accounting firm. As such, all services provided by the accounting firm as set forth in the table below under Principal Accounting Fees and Services were approved by the Audit Committee. The Audit Committee has considered the role of the independent registered public accounting firm in providing tax and other non-audit services to us and has concluded that these services are compatible with the accounting firm’s independence as our independent auditors.

Principal Accounting Fees and Services

The following table sets forth the fees accrued or paid to GT, the auditor that served as our independent registered public accounting firm for the fiscal years ended June 30, 2023 and June 30, 2024.

Vote Required and Board of Directors’ Recommendation

Stockholder ratification of the appointment of GT as our independent registered public accounting firm is not required by our bylaws or otherwise by law. Our Board, however, is submitting the appointment of GT to stockholders for ratification as a matter of good corporate practice. If stockholders fail to ratify the appointment, the Audit Committee will reconsider the selection. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Approval of this proposal requires the affirmative vote of a majority of the votes cast for or against the proposal, as well as the presence of a quorum representing a majority of the shares of our common stock entitled to vote at the Annual Meeting, present in person or represented by proxy. Abstentions and non-votes will be counted as present for purposes of determining the presence of a quorum, but will not have any effect on the outcome of the vote on this proposal. If you sign and return a proxy card without giving specific voting instructions on this proposal, your shares will be voted in favor of the proposal.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE SELECTION OF GRANT THORNTON LLP TO SERVE AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING JUNE 30, 2025.

PROPOSAL FOUR:

APPROVAL OF AMENDMENT AND RESTATEMENT OF THE EXTREME NETWORKS, INC. AMENDED AND RESTATED 2013 EQUITY INCENTIVE PLAN

The Company’s stockholders are being asked to approve the amendment and restatement of the Extreme Networks, Inc. 2013 Amended and Restated Equity Incentive Plan (which we refer to in this Proposal as the Amended Equity Plan), which would increase the number of shares issuable under the current 2013 Plan (which we refer to in this Proposal as the “Current Equity Plan”) by 2,300,000 shares, which, if granted only in the form of RSUs or other full value awards, would allow for the issuance of only up to approximately 1,533,333 shares. On November 20, 2013, the Board first adopted the Extreme Networks, Inc. 2013 Equity Incentive Plan, which was subsequently amended and restated effective November 9, 2017, on November 7, 2019, on November 4, 2021, on November 17, 2022, and again on November 8, 2023. On September 17, 2024, our Board approved the Amended Equity Plan, the amendment and restatement of the Current Equity Plan, subject to stockholder approval.

As of September 17, 2024, the Current Equity Plan had approximately 8,752,446 shares remaining available for issuance pursuant to awards granted under the plan. We consider the addition of 2,300,000 shares to the Amended Equity Plan to be very important to the future of the Company. We believe that the current share reserve in the Current Equity Plan will not be sufficient to provide meaningful equity incentives to our employees so that we may continue to compete successfully for talent and to achieve our corporate goals.

Our Board is requesting this vote by the stockholders to approve the increase of 2,300,000 shares available for issuance under the Amended Equity Plan. If the stockholders do not approve the Amended Equity Plan, the Amended Equity Plan will not become effective, the Current Equity Plan will continue in effect pursuant to its current terms and conditions, and we may continue to grant awards under the Current Equity Plan, subject to its terms, conditions and limitations. Stockholders should carefully read this proxy statement in its entirety for more detailed information concerning the proposal to approve the Amended Equity Plan. Additionally, stockholders are directed to the full Amended Equity Plan, which is attached as Exhibit A to this proxy statement. Any summary of the Amended Equity Plan is qualified in its entirety by reference to the Amended Equity Plan.

Overview

We operate in a challenging marketplace in which our success depends to a great extent on our ability to attract and retain employees, directors and other service providers of the highest caliber. One of the tools our Board regards as essential in addressing these challenges is a competitive equity incentive program. Our stock incentive program provides a range of incentive tools and sufficient flexibility to permit the Compensation Committee of the Board to implement them in ways that will make the most effective use of the shares that our stockholders authorize for incentive purposes. We intend to use these incentives to attract new key employees and to continue to retain existing key employees, directors and other service providers for the long-term benefit of the Company and its stockholders.

The Current Equity Plan allows the Company to grant equity compensation awards to employees (including officers), consultants and non-employee directors of the Company and the employees and consultants of its parent or subsidiaries. The Current Equity Plan permits the Company to grant service-based awards and performance-based awards. The Current Equity Plan provides that 52,700,000 shares may be issued under the plan (as well as up to 6,628,643 shares under the Predecessor Plan (as defined in the Current Equity Plan), and the plan includes a fungible share reserve whereby each share subject to a full value award granted under the Current Equity Plan results in decreasing the Current Equity Plan share reserve by 1.5 shares. Full value awards are equity awards other than options, stock appreciation rights (“SARs”) or stock purchase rights (or other awards under which the Company receives the fair market value of the shares subject to the award), and include restricted stock and RSUs.

As of September 17, 2024, the Current Equity Plan had approximately 8,752,446 shares remaining available for issuance pursuant to awards granted under the plan. The Company is asking its stockholders to approve adding 2,300,000 shares of our common stock to those reserved for issuance under the Amended Equity Plan, which would be reduced to 1,533,333 shares of our common stock if all were issued pursuant to full-value awards.

If the Company’s stockholders do not approve this proposal, the Company may not be able to continue to offer competitive equity packages to retain current employees and employees hired in fiscal year 2025 and later. We would also lose a major tool in

aligning the interests of our executives and employees with those of the Company’s stockholders. In the event the Company’s stockholders do not approve the Amended Equity Plan to increase the share reserve, the proposed amendment will not take effect and the Current Equity Plan will continue to be administered in its current form without any increase in the Current Equity Plan’s share reserve and without implementation of the other terms described above.

Proposed Amendments to the Current Equity Plan

The Amended Equity Plan implements the following changes to the Current Equity Plan:

Why the Company Stockholders Should Vote for the Amended Equity Plan

The following summarizes some of the reasons why we believe the Company’s stockholders should approve this proposal.

Equity Compensation Awards Allow the Company to Implement its Philosophy of Pay for Performance - The Company uses a mix of service-based awards and performance-based awards for its executive officers and other employees as discussed in more detail in the Compensation Discussion and Analysis. The performance-based awards are eligible to vest only if certain performance milestones are achieved. If the Company’s stockholders approve the Amended Equity Plan, the Company will be able to continue to use equity awards to emphasize the achievement of important business objectives of the Company and, consistent with its pay-for-performance compensation philosophy, directly link executive pay with performance.

We believe that our employees are the Company’s most valuable asset. Accordingly, the approval of the Amended Equity Plan is in the best interest of our stockholders, as equity awards granted under the Amended Equity Plan will help the Company to:

If the Company’s stockholders do not approve the Amended Equity Plan, the Company’s growth could be significantly hampered and its ability to operate its business could be adversely affected. If we do not have sufficient shares in the plan to provide meaningful equity incentives, the Company may be compelled to instead offer additional cash-based incentives to compete for talent, which could have a significant effect upon its quarterly results of operations, its cash flow, and its balance sheet. Moreover, this would not be competitive with most other technology companies where equity compensation is an integral part of the compensation offered by these firms. The Company’s success over the next few years will depend heavily on its ability to attract and retain high caliber employees, consultants and board members. The ability to grant equity awards is a necessary and powerful recruiting and retention tool for the Company to hire and motivate the quality personnel it needs to move its business forward.

If we do not increase the shares available for issuance under our equity plan, we would expect to, based on historical usage rates of shares under our Current Equity Plan, exhaust the share limit under the Current Equity Plan in or around August 2025, at which time we would lose an important compensation tool aligned with stockholder interests to attract, motivate and retain highly qualified talent.

Based on historical usage, we estimate that the shares reserved for issuance under the Amended Equity Plan would be sufficient for approximately 1 year of awards, assuming we continue to grant awards consistent with our historical usage and current practices, as reflected in our three-year average burn rate, and noting that future circumstances may require us to change our current equity grant practices. Based on the foregoing, we expect that we would require an additional increase to the share reserve under the Amended Equity Plan in approximately 1 year, noting that we may require an increase to the share reserve under the Amended Equity Plan earlier or later than 1 year depending on factors such as the future price of our shares, our future equity grant practices, and our hiring activity during the next few years, which we cannot predict with any degree of certainty at this time.

The total aggregate equity value of the additional authorized shares being requested under the Amended Equity Plan (above the shares remaining available for issuance under the Current Equity Plan), based on the closing price for one common share on September 17, 2024 is $34,937,000.

We Manage Our Equity Incentive Program Thoughtfully - We manage our long-term stockholder dilution by limiting the number of equity awards granted annually and limiting what we grant to what we believe is an appropriate amount of equity necessary to attract, reward and retain employees. In addition, in fiscal 2024, the Company repurchased approximately 2,365,215 shares of our common stock, which further mitigates the effect of our equity incentive program. On May 17, 2022, the Board approved a share repurchase authorization of $200 million over a three-year period beginning July 1, 2022.

As of September 17, 2024, equity awards outstanding under all of the Company’s equity plans (including the Current Equity Plan) were approximately 1,037,648 stock options, no unvested shares of restricted stock, 6,018,697 RSUs and 2,180,598 performance based restricted stock units (“PSUs”) (based on achievement at target). As of September 17, 2024, we had 132,046,287 shares outstanding. Accordingly, our approximately 8,199,295 outstanding awards (not including awards under our employee stock purchase plan) plus 8,752,446 shares available for future grant under the Company’s equity plans (not including under our employee stock purchase plan) as of September 17, 2024 represented approximately 13.62% of our common stock outstanding (commonly referred to as the “overhang”).

As of September 17, 2024, the average weighted per share exercise price of all outstanding stock options (whether granted under the Current Equity Plan, under equity plans assumed in connection with corporate transactions or under our previous equity plans) was $6.58 and the weighted average remaining contractual term was 1.56 years. No performance-based or service-based options were granted, earned, cancelled, or forfeited in fiscal 2022, fiscal 2023, or fiscal 2024.

The table below sets forth additional historical overhang and burn rate metrics, with the burn rates below reflecting a three-year simple average burn rate of 3.67% and a three-year simple average net burn rate of 3.07% over fiscal years 2022, 2023 and 2024.

Performance-Based Full Value Award Activity(1)

Service-Based Full Value Award Activity(1)

The Amended Equity Plan Reflects Compensation and Governance Best Practices - The Amended Equity Plan continues a broad range of compensation and governance best practices as under the Current Equity Plan, with some of the key features as follows:

New Plan Benefits

Except as provided under the Company’s director compensation program with respect to annual RSU grants to our non-employee directors, the actual number of awards (if any) that an executive officer, employee or consultant of the Company or its parent or subsidiaries or a non-employee director of the Company may receive under the Amended Equity Plan is at the discretion of the Compensation Committee and therefore cannot be determined in advance.

The following table sets forth the awards to be received under the Amended Equity Plan, to the extent currently determinable:

Summary Description of the Amended Equity Plan

The following summary of the Amended Equity Plan is qualified in its entirety by the specific language of the Amended Equity Plan, a copy of which is attached to this proxy statement as Exhibit A.

General - The purpose of the Amended Equity Plan is to advance the interests of the Company and its stockholders by providing an incentive program that will enable the Company to attract and retain employees, consultants and directors and to provide them with an equity interest in the growth and profitability of the Company. These incentives may be provided through the grant of stock options, SARs, restricted stock purchase rights, restricted stock bonuses, RSUs, performance shares, PSUs, and other share-based awards and cash-based awards.

Authorized Shares - The maximum aggregate number of shares authorized for issuance under the Amended Equity Plan is the sum of 55,000,000 shares plus up to 6,628,643 additional shares, comprised of the number of shares remaining available for grant under the Company’s 2005 Equity Incentive Plan immediately prior to its termination. In addition, to comply with applicable tax rules, the Amended Equity Plan also limits to 55,000,000 the number of shares that may be issued upon the exercise of incentive stock options granted under the Amended Equity Plan.

Share Counting - Each share subject to a stock option, stock appreciation right, or other award that requires the participant to purchase shares for their fair market value determined at the time of grant will reduce the number of shares remaining available for grant under the Amended Equity Plan by one share. However, each share subject to a “full value” award (i.e., an award settled in stock, other than an option, stock appreciation right, or other award that requires the participant to purchase shares for their fair market value determined at grant) will reduce the number of shares remaining available for grant under the Amended Equity Plan by 1.5 shares.

If any award granted under the Amended Equity Plan expires or otherwise terminates for any reason without having been exercised or settled in full, or if shares subject to forfeiture or repurchase are forfeited or repurchased by the Company for not more than the participant’s purchase price, any such shares reacquired or subject to a terminated award will again become available for issuance under the Amended Equity Plan.

Shares will not be treated as having been issued under the Amended Equity Plan and will therefore not reduce the number of shares available for issuance to the extent an award is settled in cash. Shares that are withheld or reacquired by the Company in satisfaction of a tax withholding obligation in connection with the exercise of settlement of an option or a stock appreciation right will not be made available for new awards under the Amended Equity Plan. Upon the exercise of a stock appreciation right or net-exercise of an option, the number of shares available under the Amended Equity Plan will be reduced by the gross number of shares for which the award is exercised.

Adjustments for Capital Structure Changes - Appropriate and proportionate adjustments will be made to the number of shares authorized under the Amended Equity Plan and to outstanding awards in the event of any change in our common stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination

of shares, exchange of shares or similar change in our capital structure, or if we make a distribution to our stockholders in a form other than common stock (excluding regular, periodic cash dividends) that has a material effect on the fair market value of our common stock. In such circumstances, the Compensation Committee also has the discretion under the Amended Equity Plan to adjust other terms of outstanding awards as it deems appropriate.

Nonemployee Director Award Limits - The sum of the grant date fair value of all equity-based awards and any cash compensation provided to a service provider as compensation for services as a non-employee director may not exceed $750,000 for each calendar year.

Administration - The Amended Equity Plan generally will be administered by the Compensation Committee, although the Board retains the right to appoint another of its committees to administer the Amended Equity Plan or to administer the Amended Equity Plan directly. For purposes of this summary, the term “Compensation Committee” will refer to either such duly appointed committee or the Board of Directors. Subject to the provisions of the Amended Equity Plan, the Compensation Committee determines in its discretion the persons to whom and the times at which awards are granted, the types and sizes of awards, and all of their terms and conditions. The Compensation Committee may, except as provided by the Amended Equity Plan, amend, cancel or renew any award, waive any restrictions or conditions applicable to any award, and accelerate, continue, extend or defer the vesting of any award.

The Amended Equity Plan provides, subject to certain limitations, for indemnification by the Company of any director, officer or employee against all reasonable expenses, including attorneys’ fees, incurred in connection with any legal action arising from such person’s action or failure to act in administering the Amended Equity Plan. All awards granted under the Amended Equity Plan will be evidenced by a written or digitally signed agreement between the Company and the participant specifying the terms and conditions of the award, consistent with the requirements of the Amended Equity Plan. The Compensation Committee will interpret the Amended Equity Plan and awards granted under it, and all determinations of the Compensation Committee generally will be final and binding on all persons having an interest in the Amended Equity Plan or any award.

Prohibition of Option and SAR Repricing - The Amended Equity Plan expressly provides that, without the approval of a majority of the votes cast in person or by proxy at a meeting of our stockholders, the Compensation Committee may not provide for any of the following with respect to underwater options or stock appreciation rights: (1) either the cancellation of such outstanding options or stock appreciation rights in exchange for the grant of new options or stock appreciation rights at a lower exercise price or the amendment of outstanding options or stock appreciation rights to reduce the exercise price, (2) the issuance of new full value awards in exchange for the cancellation of such outstanding options or stock appreciation rights, or (3) the cancellation of such outstanding options or stock appreciation rights in exchange for payments in cash.

Eligibility - Awards may be granted to employees, directors and consultants of the Company or any present or future parent or subsidiary corporation or other affiliated entity of the Company. Incentive stock options may be granted only to employees who, as of the time of grant, are employees of the Company or any parent or subsidiary corporation of the Company. As of September 17, 2024, we had approximately 2,708 employees worldwide (including three executive officers), 234 consultants and six non-employee directors who would be eligible to receive awards under the Amended Equity Plan.

Vesting - Awards under the Amended Equity Plan granted on or after November 9, 2017 (excluding any substitute grants made in connection with a merger or other corporate transaction) will vest no earlier than the first anniversary of the date the award is granted. However, the Compensation Committee may provide that such vesting restrictions lapse or are waived upon the participant’s death, disability, termination of service or the consummation of a change of control. In addition, the Compensation Committee may grant awards that will result in the issuance of up to 5% of the shares reserved for issuance under the Amended Equity Plan without regard to the minimum vesting provisions and awards to non-employee directors may vest on the earlier of the first anniversary of the date of grant or the next annual meeting of stockholders (provided that such vesting period may not be less than 50 weeks after grant).

Stock Options - The Compensation Committee may grant non-statutory stock options, incentive stock options within the meaning of Section 422 of the Code, or any combination of these. The exercise price of each option may not be less than 100% of the fair market value of a share of our common stock on the date of grant. However, any incentive stock option granted to a person who at the time of grant owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company (a “10% Stockholder”) must have an exercise price equal to at least 110% of the fair market value of a share of common stock on the date of grant.

The Amended Equity Plan provides that the option exercise price may be paid in cash, by check, or cash equivalent, or if permitted by the Compensation Committee, by means of a broker-assisted cashless exercise; by means of a net-exercise procedure;

to the extent legally permitted, by tender to the Company of shares of common stock owned by the participant having a fair market value not less than the exercise price; by such other lawful consideration as approved by the Compensation Committee; or by any combination of these. Nevertheless, the Compensation Committee may restrict the forms of payment permitted in connection with any option grant. No option may be exercised unless the participant has made adequate provision for federal, state, local and foreign taxes, if any, relating to the exercise of the option, including, if permitted or required by the Company, through the participant’s surrender of a portion of the option shares to the Company.

Options will become vested and exercisable at such times or upon such events and subject to such terms, conditions, performance criteria or restrictions as specified by the Compensation Committee. The maximum term of any option granted under the Amended Equity Plan is seven years, provided that an incentive stock option granted to a 10% Stockholder must have a term not exceeding five years. Unless otherwise permitted by the Compensation Committee, an option generally will remain exercisable for three months following the participant’s termination of service, provided that if service terminates as a result of the participant’s death or disability, the option generally will remain exercisable for 12 months, but in any event the option must be exercised no later than its expiration date, and provided further that an option will terminate immediately upon a participant’s termination for cause (as defined by the Amended Equity Plan) or if the participant engages in any act constituting cause after termination, during any period in which any option otherwise would remain exercisable.

Options are nontransferable by the participant other than by will or by the laws of descent and distribution, and are exercisable during the participant’s lifetime only by the participant. However, an option may be assigned or transferred to the extent permitted by the Compensation Committee and set forth in the applicable award agreement. In the case of an incentive stock option, such assignment or transfer is only permitted to the extent that the transfer will not terminate its tax qualification.

Stock Appreciation Rights - The Compensation Committee may grant stock appreciation rights either in tandem with a related option (a “Tandem SAR”) or independently of any option (a “Freestanding SAR”). A Tandem SAR requires the option holder to elect between the exercise of the underlying option for shares of common stock or the surrender of the option and the exercise of the related stock appreciation right. A Tandem SAR is exercisable only at the time and only to the extent that the related stock option is exercisable, while a Freestanding SAR is exercisable at such times or upon such events and subject to such terms, conditions, performance criteria or restrictions as specified by the Compensation Committee. The exercise price of each stock appreciation right may not be less than 100% of the fair market value of a share of our common stock on the date of grant.

Upon the exercise of any stock appreciation right, the participant is entitled to receive an amount equal to the excess of the fair market value of the underlying shares of common stock as to which the right is exercised over the aggregate exercise price for such shares. Payment of this amount upon the exercise of a Tandem SAR may be made only in shares of common stock whose fair market value on the exercise date equals the payment amount. At the Compensation Committee’s discretion, payment of this amount upon the exercise of a Freestanding SAR may be made in cash or shares of common stock. The maximum term of any stock appreciation right granted under the Amended Equity Plan is seven years.

Stock appreciation rights are generally nontransferable by the participant other than by will or by the laws of descent and distribution, and are generally exercisable during the participant’s lifetime only by the participant. If permitted by the Compensation Committee, a Tandem SAR related to a non-statutory stock option and a Freestanding SAR may be assigned or transferred to certain family members or trusts for their benefit to the extent permitted by the Compensation Committee and set forth in the applicable award agreement. Other terms of stock appreciation rights are generally similar to the terms of comparable stock options.

Restricted Stock Awards - The Compensation Committee may grant restricted stock awards under the Amended Equity Plan either in the form of a restricted stock purchase right, giving a participant an immediate right to purchase common stock, or in the form of a restricted stock bonus, in which stock is issued in consideration for services to the Company rendered by the participant. The Compensation Committee determines the purchase price payable under restricted stock purchase awards, which may be less than the then current fair market value of our common stock. Restricted stock awards may be subject to vesting conditions based on such service or performance criteria as the Compensation Committee specifies, including the attainment of one or more performance goals similar to those described below in connection with performance awards. Shares acquired pursuant to a restricted stock award may not be transferred by the participant until vested. Unless otherwise provided by the Compensation Committee, (i) a participant will forfeit any shares of restricted stock acquired from a restricted stock bonus as to which the vesting restrictions have not lapsed prior to the participant’s termination of service and (ii) the Company will have the right to repurchase from the participant, for the purchase price paid by the participant, any restricted stock acquired by the participant pursuant to a restricted stock purchase right as to which the vesting restrictions have not lapsed prior to the participant’s termination of service. Unless otherwise determined by the Compensation Committee, participants holding restricted stock will have the right to vote the shares and to receive any dividends paid, except that dividends may not be paid until the applicable restricted stock vests.

Restricted Stock Units - The Compensation Committee may grant RSUs under the Amended Equity Plan, which represent rights to receive shares of our common stock at a future date determined in accordance with the participant’s award agreement. No monetary payment is required for receipt of RSUs or the shares issued in settlement of the award, the consideration for which is furnished in the form of the participant’s services to the Company. The Compensation Committee may grant RSU awards subject to vesting conditions based on such service or performance criteria as the Compensation Committee specifies and as set forth in the applicable award agreement. Unless otherwise provided by the Compensation Committee, a participant will forfeit any RSUs which have not vested prior to the participant’s termination of service. Participants have no voting rights or rights to receive cash dividends with respect to RSU awards until shares of common stock are issued in settlement of such awards. However, the Compensation Committee may grant RSUs that entitle their holders to dividend equivalent rights, which are rights to receive cash or additional RSUs whose value is equal to any cash dividends the Company pays. Dividend equivalents may accrue on RSUs but shall not be payable unless and until the applicable award vests.

Performance Awards - The Compensation Committee may grant performance awards subject to such conditions and the attainment of such performance goals over such periods as the Compensation Committee determines in writing and sets forth in a written agreement between the Company and the participant. These awards may be designated as performance shares or performance units, which consist of unfunded bookkeeping entries generally having initial values equal to the fair market value determined on the grant date of a share of common stock in the case of performance shares and a monetary value established by the Compensation Committee at the time of grant in the case of performance units. Each performance award agreement will specify a predetermined amount of performance shares or performance units that may be earned by the participant to the extent that one or more performance goals are attained within a predetermined performance period. To the extent earned, performance awards may be settled in cash, shares of common stock (including shares of restricted stock that are subject to additional vesting) or any combination of these.

The Compensation Committee, in its discretion, may base performance goals on one or more of the following measures (or such other measure established by the Compensation Committee): revenue; sales; expenses; operating income; gross margin; operating margin; earnings before any one or more of: share-based compensation expense, interest, taxes, depreciation and amortization; pre-tax profit; net operating income; net income; economic value added; free cash flow; operating cash flow; balance of cash, cash equivalents and marketable securities; stock price; earnings per share; return on stockholder equity; return on capital; return on assets; return on investment; total stockholder return; employee satisfaction; employee retention; market share; customer satisfaction; product development; research and development expense; completion of an identified special project; completion of a joint venture or other corporate transaction and new customer acquisition.

The target levels with respect to these performance measures may be expressed on an absolute basis or relative to an index, budget or other standard specified by the Compensation Committee. The degree of attainment of performance measures will be calculated prior to the accrual or payment of any performance award for the same performance period, in accordance with generally accepted accounting principles (GAAP), if applicable, or any other methodology established by the Committee prior to the grant of the performance award, excluding the effect (whether positive or negative) of changes in accounting standards or any extraordinary, unusual or nonrecurring item occurring after the establishment of the performance goals applicable to a performance award.

In its discretion, the Compensation Committee may provide for a participant awarded performance shares to receive dividend equivalent rights with respect to cash dividends paid on our common stock to the extent of the performance shares that are earned and become nonforfeitable. The Compensation Committee may provide for performance award payments in lump sums or installments.

No performance award may be sold or transferred other than by will or the laws of descent and distribution prior to the end of the applicable performance period.

Cash-Based Awards and Other Stock-Based Awards - The Compensation Committee may grant cash-based awards or other stock-based awards in such amounts and subject to such terms and conditions as the Compensation Committee determines. Cash-based awards will specify a monetary payment or range of payments, while other stock-based awards will specify a number of shares or units based on shares or other equity-related award. Such awards may be subject to vesting conditions based on continued performance of service or subject to the attainment of one or more performance goals similar to those described above in connection with performance awards. Settlement of awards may be in cash, other property or shares of common stock, as determined by the Compensation Committee. A participant will have no voting rights with respect to any such award unless and until shares are issued pursuant to the award. The Compensation Committee may grant dividend equivalent rights with respect to other stock-based awards. Dividend equivalents may accrue on stock-based awards, but shall not be payable unless and until the applicable award vests.

Dividend equivalents are not payable with respect to options or SARs. The effect on such awards of the participant’s termination of service will be determined by the Compensation Committee and set forth in the participant’s award agreement.

Change in Control - Unless otherwise defined in a participant’s award or other agreement with the Company, the Amended Equity Plan provides that a “Change in Control” generally occurs upon (a) a person or entity (with certain exceptions described in the Amended Equity Plan) becoming the direct or indirect beneficial owner of more than 50% by voting power or fair market value of the Company’s voting stock; (b) stockholder approval of a liquidation or dissolution of the Company; or (c) the occurrence of any of the following events upon which the stockholders of the Company immediately before the event do not retain immediately after the event direct or indirect beneficial ownership of more than 50% of the combined voting power of the voting securities of the Company, its successor or the entity to which the assets of the company were transferred: (i) a sale or exchange by the stockholders in a single transaction or series of related transactions of more than 50% of the combined voting power of the Company’s voting stock; (ii) a merger or consolidation in which the Company is a party; or (iii) the sale, exchange or transfer of all or substantially all of the assets of the Company (other than a sale, exchange or transfer to one or more subsidiaries of the Company).

The Amended Equity Plan does not provide for any automatic single trigger acceleration upon a Change in Control, other than with respect to awards held by non-employee directors. Instead, if a Change in Control occurs, the surviving, continuing, successor or purchasing entity or its parent may, without the consent of any participant, either assume or continue outstanding awards or substitute substantially equivalent awards for its stock. If so determined by the Compensation Committee, stock-based awards will be deemed assumed if, for each share subject to the award prior to the Change in Control, its holder is given the right to receive the same amount of consideration that a stockholder would receive as a result of the Change in Control. Any awards which are not assumed or continued in connection with a Change in Control will vest in full effective immediately prior to the Change in Control, and, except as otherwise provided in an award agreement, for each such award that vests subject to the attainment of one or more performance goals, the applicable performance goals will be deemed achieved at the greater of target or actual performance (with the performance goals equitably adjusted to reflect a shortened performance period ending as of the Change in Control). The Compensation Committee may also provide in the grant of any award or at any other time may take such action as it deems appropriate to provide for acceleration of the exercisability, vesting and/or settlement of each or any outstanding award or portion thereof and shares acquired pursuant thereto upon the termination of a participant’s service in connection with a Change in Control. Under the CiC Plan (as defined below), upon the occurrence of a Change in Control, equity awards held by the named executive officers that are not assumed or otherwise continued by an acquirer will accelerate in full immediately prior to the Change in Control, with each performance-based equity award deemed achieved at the greater of target or actual achievement (with performance goals equitably adjusted if necessary to reflect a truncated performance period) unless otherwise provided in an applicable award agreement. The vesting of all awards held by non-employee directors will be accelerated in full upon a Change in Control pursuant to our director compensation program.

Awards Subject to Section 409A of the Code - Certain awards granted under the Amended Equity Plan may be deemed to constitute “deferred compensation” within the meaning of Section 409A of the Code, providing rules regarding the taxation of nonqualified deferred compensation plans, and the regulations and other administrative guidance issued pursuant to Section 409A. Any such awards will be required to comply with the requirements of Section 409A. Notwithstanding any provision of the Amended Equity Plan to the contrary, the Compensation Committee is authorized, in its sole discretion and without the consent of any participant, to amend the Amended Equity Plan or any award agreement as it deems necessary or advisable to comply with Section 409A.

Amendment, Suspension or Termination - The Amended Equity Plan will continue in effect until its termination by the Compensation Committee, provided that no awards may be granted under the Amended Equity Plan following the tenth anniversary of the Amended Equity Plan’s effective date, which will be the date on which it is approved by the stockholders. The Compensation Committee may amend, suspend or terminate the Amended Equity Plan at any time, provided that no amendment may be made without stockholder approval that would increase the maximum aggregate number of shares of stock authorized for issuance under the Amended Equity Plan, change the class of persons eligible to receive incentive stock options or require stockholder approval under any applicable law. No amendment, suspension or termination of the Amended Equity Plan may affect any outstanding award unless expressly provided by the Compensation Committee, and, in any event, may not have a materially adverse effect on an outstanding award without the consent of the participant unless necessary to comply with any applicable law, regulation or rule, including, but not limited to, Section 409A of the Code.

Withholding - As a condition to the issuance or delivery of stock or payment of other compensation pursuant to the exercise or lapse of restrictions on any award, the Company requires participants to discharge all applicable withholding tax obligations. Shares held by or to be issued to a participant may be used to discharge statutory tax withholding obligations at up to the applicable maximum statutory tax withholding rate.

Summary of U.S. Federal Income Tax Consequences - The following summary is intended only as a general guide to the U.S. federal income tax consequences of participation in the Amended Equity Plan and does not attempt to describe all possible federal or other tax consequences of such participation or tax consequences based on particular circumstances.

Incentive Stock Options - A participant recognizes no taxable income for regular income tax purposes as a result of the grant or exercise of an incentive stock option qualifying under Section 422 of the Code. Participants who neither dispose of their shares within two years following the date the option was granted nor within one year following the exercise of the option will normally recognize a capital gain or loss upon the sale of the shares equal to the difference, if any, between the sale price and the purchase price of the shares. If a participant satisfies such holding periods upon a sale of the shares, we will not be entitled to any deduction for federal income tax purposes. If a participant disposes of shares within two years after the date of grant or within one year after the date of exercise (a “disqualifying disposition”), the difference between the fair market value of the shares on the option exercise date and the exercise price (not to exceed the gain realized on the sale if the disposition is a transaction with respect to which a loss, if sustained, would be recognized) will be taxed as ordinary income at the time of disposition. Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. Any ordinary income recognized by the participant upon the disqualifying disposition of the shares generally should be deductible by us for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of the Code.

In general, the difference between the option exercise price and the fair market value of the shares on the date of exercise of an incentive stock option is treated as an adjustment in computing the participant’s alternative minimum taxable income and may be subject to an alternative minimum tax which is paid if such tax exceeds the regular tax for the year. Special rules may apply with respect to certain subsequent sales of the shares in a disqualifying disposition, certain basis adjustments for purposes of computing the alternative minimum taxable income on a subsequent sale of the shares and certain tax credits which may arise with respect to participants subject to the alternative minimum tax.

Non-statutory Stock Options - Options not designated or qualifying as incentive stock options are non-statutory stock options having no special tax status. A participant generally recognizes no taxable income upon receipt of such an option. Upon exercising a non-statutory stock option, the participant normally recognizes ordinary income equal to the difference between the exercise price paid and the fair market value of the shares on the date when the option is exercised. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of stock acquired by the exercise of a non-statutory stock option, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the exercise date, will be taxed as capital gain or loss. We generally should be entitled to a tax deduction equal to the amount of ordinary income recognized by the participant as a result of the exercise of a non-statutory stock option, except to the extent such deduction is limited by applicable provisions of the Code.

Stock Appreciation Rights - A Participant recognizes no taxable income upon the receipt of a stock appreciation right. Upon the exercise of a stock appreciation right, the participant generally will recognize ordinary income in an amount equal to the excess of the fair market value of the underlying shares of common stock on the exercise date over the exercise price. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant in connection with the exercise of the stock appreciation right, except to the extent such deduction is limited by applicable provisions of the Code.

Restricted Stock - A participant acquiring restricted stock generally will recognize ordinary income equal to the excess of the fair market value of the shares on the “determination date” over the price paid, if any, for such shares. The “determination date” is the date on which the participant acquires the shares unless the shares are subject to a substantial risk of forfeiture and are not transferable, in which case the determination date is the earlier of (i) the date on which the shares become transferable or (ii) the date on which the shares are no longer subject to a substantial risk of forfeiture (e.g., when they become vested). If the determination date follows the date on which the participant acquires the shares, the participant may elect, pursuant to Section 83(b) of the Code, to designate the date of acquisition as the determination date by filing an election with the Internal Revenue Service no later than 30 days after the date on which the shares are acquired. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of shares acquired pursuant to a restricted stock award, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date, will be taxed as capital gain or loss. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

Restricted Stock Unit, Performance, Cash-Based and Other Stock-Based Awards – A participant generally will recognize no income upon the grant of an RSU, performance share, PSU, cash-based or other stock-based award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of settlement in an amount equal to

the cash received and the fair market value of the shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Any further gain or loss will be taxed as capital gain or loss. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

Section 162(m) of the Code - In general, under Section 162(m) of the Code, publicly held corporations like the Company may only take income tax deductions in respect of total compensation (including base salary, annual bonus, stock option exercises and non-qualified benefits) paid to certain executive officers of up to $1.0 million in any taxable year of the corporation. Prior to the Tax Cuts and Jobs Act of 2017, the deduction limit did not apply to certain “qualified performance-based compensation.” However, following the effectiveness of the new rules, which generally apply to taxable years beginning after December 31, 2017, such “qualified performance-based compensation” exception is no longer applicable unless provided pursuant to a written binding contract in effect on November 2, 2017 that is not modified in any material respect after that date.

Tax Consequences to the Company – In general, the Company should be entitled to a deduction when a participant recognizes compensation income; however, any such deduction will be subject to the limitations of Section 162(m) of the Code as described above.

Fiscal 2024 Compensation Decisions

For the fiscal year ended June 30, 2024, our named executive officers, or NEOs, and their respective titles were as follows:

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

This Compensation Discussion and Analysis explains the objectives and operation of the Company’s executive compensation program in fiscal 2024, particularly with respect to the Company’s NEOs. The Compensation Committee oversees the Company’s compensation programs and has the sole authority to establish the compensation paid to the Company’s NEOs.

Fiscal 2024 Business Performance Highlights

The Company achieved its fourth consecutive year of exceeding $1.0 billion in Net Revenues. The continued improvement in our supply chain environment and the strong growth in our subscriptions contributed to the revenue results in fiscal 2024. Our operating expenses reflect our ongoing strategies to lower our operational costs.

During fiscal 2024, we remained focused on executing our operational priorities and improving our liquidity. The Company continued its cost cutting strategies during fiscal 2024. The Company generated positive cash flows from operations for fiscal 2024. Our financial performance during fiscal 2024 was as follows:

A GAAP to non-GAAP reconciliation for non-GAAP performance measures is provided in this proxy statement under the section “Non-GAAP Measures of Financial Performance – GAAP to Non-GAAP Reconciliation.”

(1) The Company's reported per share amount for the year ended June 30, 2024 included in this proxy statement differs by a $0.01 as compared to the amounts reported on the Company's Form 8-K filed with the SEC on August 7, 2024 due to a correction in shares used in the per share calculation for that period.

The following charts depict our Total Shareholder Return (“TSR”) for the one-, three-, and five-year periods ending June 30, 2024 on a compounded annual growth rate and absolute basis.

Fiscal 2024 Compensation Was Closely Aligned With Performance

Our executive compensation programs are designed to deliver pay in accordance with corporate and individual performance. For fiscal 2024, our performance was reflected in the compensation of our NEOs in a number of ways:

In fiscal 2024, the Compensation Committee granted time-based RSUs to our NEOs, other than Mr. Rhodes, that vest based on continued service over three years, to encourage retention while further tying realizable compensation from such equity awards to the Company’s long-term stock price.

Because Mr. Rhodes' new hire awards were granted in late fiscal 2023, he did not receive an equity award in fiscal 2024.

Chief Executive Officer ("CEO") Target Compensation versus Estimated Realizable Compensation

The strong link between pay and performance is further illustrated by the chart below, which shows that our CEO’s estimated realizable pay for fiscal years 2022, 2023 and 2024 was on average 96% of his target direct compensation. While the Summary Compensation Table reflects a measure of total compensation that includes the grant date fair value for equity awards, we believe that an assessment can be made by considering our CEO’s estimated realizable pay, which is based on the value of equity awards at vesting or exercise (or the end of fiscal year 2024 if not yet vested or exercised), and provides another important perspective on our CEO’s compensation package insomuch as it shows the amounts actually earned. The following graph illustrates the impact of our performance-based compensation programs on the total compensation of our CEO and compares his targeted compensation to estimated realizable pay as of June 30, 2024.

Compensation Philosophy and Objectives

Our guiding principle in establishing executive compensation is to align compensation with the creation of stockholder value while achieving the Company’s strategic objectives and financial goals. Consistent with this principle, we seek to provide a competitive total compensation package that allows us to attract high quality candidates for senior leadership positions, to retain these employees, and to establish a total compensation program which motivates and rewards individual and team performance in alignment with our short- and long-term business strategies and objectives. Our compensation program is designed to provide accountability at both the individual and team level with respect to both absolute and relative competitive performance. We also align the interests of our executives and our stockholders by providing variable compensation to our executives that is directly linked to the performance of the Company and to our stock price. As illustrated below, a substantial portion of our NEOs’ fiscal 2024 compensation (PSUs, including SLTI PSUs for our CEO, and short-term cash incentives) was directly tied to the Company's financial and stock price performance. The graph below consists of base salary, bonuses, actual short-term cash incentives and the grant-date value of equity awards granted during fiscal 2024.

(1) Fiscal 2024 other NEO pay mix excludes Mr. Rhodes because he did not receive equity awards in fiscal 2024 and thus his fiscal 2024 total compensation is not reflective of our typical NEO pay design.

Annual compensation for a given NEO is determined with reference to competitive market data, as well as the individual’s experience, knowledge, skills, and performance. See "Compensation-Setting Process" section below for additional detail.

As noted above, a significant portion of fiscal 2024 compensation to our CEO was at risk, specifically his short-term cash incentive and his PSU awards.

Compensation Best Practices

The Company’s executive compensation program includes a number of features intended to reflect best practices and to help ensure that the program aligns with stockholder interests:

2023 “Say on Pay” Advisory Vote on Executive Compensation

The Company provided stockholders with an advisory vote on NEO compensation at the 2023 annual meeting of Stockholders. During that meeting, approximately 96% of the votes cast in the “say on pay” advisory vote were “FOR” approval of the compensation of our NEOs. The votes cast in favor indicate substantial support for the Company’s compensation programs, measures and elements for our NEOs. The Compensation Committee considered the results of our 2022 advisory vote (the most recent vote at the time when decisions were made) when making executive compensation decisions for fiscal 2024.

Compensation-Setting Process

Our Compensation Committee, in consultation with the Board and the Company’s human resources department, designs and oversees the Company’s compensation programs and compensation philosophy. Throughout the year, the Chair of our Compensation Committee meets with human resources leadership and the legal department to monitor issues relating to executive compensation. At the end of the fiscal year, our CEO conducts a qualitative and quantitative assessment of each senior officer’s (which includes our NEOs) performance for the past fiscal year based upon the officer’s individual and corporate goals and objectives, and reports to the Compensation Committee regarding his proposals regarding compensation adjustments for our NEOs (other than with respect to himself). The Compensation Committee independently assesses the performance and compensation of our CEO, and our CEO is not present in meetings when his compensation is discussed. As set forth in additional detail below, in connection with its compensation oversight and approvals, the Compensation Committee reviews:

Additional details regarding the operation and duties of the Compensation Committee are also set forth in the “Compensation Committee” section above.

Compensation Consultant

In connection with our desire to make our executive compensation competitive, to more closely tie future compensation to performance, and to further align executive compensation with the creation of stockholder value, the Compensation Committee engaged Compensia, Inc., a national compensation consulting firm with expertise in the technology sector, to assist it in the performance of its duties and to advise it with respect to compensation matters for fiscal 2024. In its role as independent compensation consultant and at the request of the Compensation Committee, Compensia participated in Compensation Committee meetings and provided compensation advice to the Compensation Committee on:

Although the Company pays Compensia’s fees for its engagement by the Compensation Committee, the Compensation Committee has sole discretion with respect to Compensia’s continued engagement and assignments. Further, the Compensation Committee has reviewed Compensia’s independence and determined that its work does not give rise to any conflicts of interest. Additional details regarding the Compensation Committee’s relationship and review of Compensia are also set forth in the “Compensation Committee” section above.

Peer Group Selection and Review

The Compensation Committee considers a variety of factors when setting the compensation of our NEOs, including competitive market data, as well as the individual’s experience, knowledge, skills, performance and need for retention. The Compensation Committee evaluates pay competitiveness on an element-by-element basis, as well as on a total compensation basis. The peer group data reviewed includes a range of pay levels including the 25th, 50th and 75th percentile of the members of the peer group to reflect the range of pay to be considered when determining individual pay elements. While the Compensation Committee does not establish compensation levels by benchmarking to a specific percentile within our peer group, the Compensation Committee

reviews the practices of members of the peer group to better understand and assess the competitiveness of the compensation that the Company pays to its executives, both with respect to each compensation element and the overall compensation package.

On February 8, 2023, following consultation with Compensia, the Compensation Committee approved our peer group for fiscal year 2024 compensation decisions. The peer group included the following companies:

For fiscal year 2024, this peer group was comprised of computer networking, communication equipment companies, cloud-oriented companies, and other technology companies with approximately $458.0 million to $2.8 billion in revenue, with a 50th percentile at $1.0 billion, and market capitalizations of approximately $564 million to $10.4 billion, with a 50th percentile at $3.6 billion, as of December 2022. The 2024 peer group better aligned with our cloud-oriented business focus and stayed within guidelines for revenue and market cap comparability. Relative to the fiscal 2023 peer group, the revised 2024 peer group excluded 8x8, Comtech Telecommunications, Mandiant, Inc. (f/k/a FireEye), Poly (f/k/a Plantronics), and Ribbon Communications, and added Five9, Qualys, Ring Central, Teradata, and Varonis Systems.

Compensation Program Elements

The principal elements of our executive compensation program and their respective purposes are as follows:

Base Salary - The base salary for each NEO initially is set at the time the NEO commences employment with the Company and is reviewed annually. In its annual review of NEO base salaries, the Compensation Committee considers the recommendations of our CEO, the performance of each NEO (as evaluated by our CEO, except with respect to his own performance), and a competitive market analysis prepared by Compensia using data gathered from the Company’s peer group with respect to base salary, total target cash compensation and target total direct compensation (which includes equity awards).

In June 2023, after taking into consideration the factors noted above, the Compensation Committee determined to increase the annual base salaries of Mr. Meyercord from $800,000 to $840,000, of Ms. Motiey from $450,000 to $485,000, and of Mr. Vitalone

from $460,000 to $485,000 for fiscal 2024. Mr. Rhodes’ base salary of $500,000 was set in connection with his commencement of employment in May 2023 and was not adjusted during fiscal 2024.

Short-Term Cash Incentives

Extreme Incentive Plan - The Compensation Committee establishes a short-term cash incentive plan each year under our EIP, which is applicable to our employees (other than sales personnel on variable compensation plans), including all of our NEOs. The EIP is designed to reward Company performance relative to our current plans and objectives, particularly in the short term. The structure and elements of the plan are reviewed and set semi-annually based upon expectations for our business derived from our annual operating plan. This approach enables the Compensation Committee to select performance metrics that are appropriate in light of evolving market conditions and areas of near-term focus.

As in fiscal 2023, the EIP approved by the Compensation Committee for fiscal 2024, provided for semi-annual payouts based on the Company’s achievement of pre-established performance goals for each of the first and second halves of fiscal 2024. The Compensation Committee implements the short-term cash incentive plan through semi-annual performance targets to allow it to better set challenging, yet reasonable goals that take into account the current economic environment, the industry and the Company’s business. The semi-annual target levels for the performance metrics during fiscal 2024 were based on projections of metrics derived from the Company’s annual operating plan.

For fiscal 2024, the EIP was funded based on the achievement of pre-established Net Revenue, Bookings Annual Contract Value ("ACV") and EBITDA performance goals. During each half, Net Revenue was weighted at 30%, Bookings ACV was weighted at 30% and EBITDA was weighted at 40%. In addition, for the second half of fiscal 2024, the Compensation Committee added a threshold requirement that non-GAAP Earnings per Share ("EPS") for the fourth quarter of fiscal 2024 must be equal to or greater than $0.20 for any EIP payout to be earned by our NEOs. Further, as the Compensation Committee reviewed the lowered targets for the second half of fiscal 2024, it decided to cap the bonus potential for the NEOs at 50% and eliminate upside potential for overperformance of the adjusted outlook. The threshold, target and maximum goals for each half of fiscal 2024 and their corresponding performance levels are set forth in the tables below. Achievement between threshold and target levels and between target and maximum levels is determined based on linear interpolation.

Bookings ACV represents the total annualized value of a contract between a company and its customer and is typically used in subscription-based businesses or service agreements.

Non-GAAP EPS represents non-GAAP net income (as discussed below) divided by diluted shares outstanding, which is calculated as GAAP weighted-average outstanding shares plus dilutive potential shares outstanding during the period.

EBITDA represents non-GAAP net income before interest expense, income tax expense and depreciation and amortization expense. Non-GAAP net income was calculated as GAAP net income, adjusted for amortization of intangibles, share-based compensation, acquisition and integration costs, restructuring charges, system transition costs, non-recurring litigation charges, debt refinancing charges and tax effect on non-GAAP adjustments. The Compensation Committee believed the adjustments used in calculating this metric better reflect how the Company measures its performance.

A GAAP to non-GAAP reconciliation for non-GAAP performance measures under the EIP is provided in this proxy statement under the section "Non-GAAP Measures of Financial Performance -- GAAP to non-GAAP Reconciliation."

The threshold, target, and maximum goals of the EIP for July 1, 2023 through December 31, 2023 (the “First Half Performance Period”) and the Company’s corresponding performance levels are set forth in the table below.
