San Jose, California 95134
NOTICE OF ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON MAY 9, 2024
To the Stockholders of Calix, Inc.:
The Annual Meeting of Stockholders (“Annual Meeting”) of Calix, Inc. (“Calix”), will be held virtually, via live webcast at www.virtualshareholdermeeting.com/CALX2024, on Thursday, May 9, 2024 at 10:45 a.m. Pacific Daylight Time. The Annual Meeting will be held for the following purposes:
1.To elect two directors to the Calix Board of Directors (“Board”);
2.To approve, on a non-binding, advisory basis, the compensation of our named executive officers (“NEOs”);
3.To ratify the selection of KPMG LLP as Calix’s independent registered public accounting firm for the fiscal year ending December 31, 2024; and
4.To transact such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.
The above items of business are more fully described in the Proxy Statement. Only stockholders of record who owned Calix common stock at the close of business on March 11, 2024 can vote at this meeting or any adjournments that take place.
We have elected to use the Internet as our primary means of providing our proxy materials to stockholders. As a result, we are sending a Notice of Internet Availability of Proxy Materials (“Notice”) rather than mailing a paper copy of this Proxy Statement and our 2023 Annual Report. The Notice will be sent on or about March 28, 2024 to our stockholders of record as of the close of business on March 11, 2024. We are also providing access to our proxy materials over the Internet beginning on or about March 28, 2024. Electronic delivery of our proxy materials minimizes printing and mailing costs and reduces the environmental impact of the proxy materials.
The Notice contains instructions for accessing the proxy materials, including the Proxy Statement and our 2023 Annual Report, and provides information on how stockholders may obtain paper copies free of charge. The Notice also provides the date and time of the virtual Annual Meeting, the matters to be acted upon at the meeting and the Board’s recommendation with regard to each matter and information on how to attend the virtual Annual Meeting and vote online.
You are cordially invited to attend the virtual Annual Meeting. Whether or not you expect to attend, you should vote and submit your proxy over the Internet following the voting procedures described in the Notice to ensure that your vote is recorded. We strongly encourage you to vote by Internet or phone by following the instructions described in the Notice. If you have requested and received paper copies of proxy materials in lieu of the Notice, we still encourage you to vote by phone, but if you do not have access to a phone you may sign, date and return by mail the proxy card sent to you.
By Order of the Board of Directors

PROXY STATEMENT
FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS
IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON MAY 9, 2024
The Board of Directors of Calix, Inc. is soliciting your proxy to vote at the virtual Annual Meeting of Stockholders to be held on May 9, 2024, at 10:45 a.m. Pacific Daylight Time, and any adjournment or postponement of that meeting (“Annual Meeting”). The Annual Meeting will be held via live webcast only at www.virtualshareholdermeeting.com/CALX2024.
We have elected to provide access to our proxy materials on the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (“Notice”) to our stockholders of record as of March 11, 2024 (“Record Date”), while brokers and other nominees who hold shares on behalf of beneficial owners will be sending their own similar notice. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or to request a printed set of the proxy materials. Instructions on how to request a printed copy by mail or email may be found in the Notice and on the website referred to in the Notice, including an option to request paper copies prior to the Annual Meeting by April 25, 2024, and thereafter on an ongoing basis until May 9, 2025. On or about March 28, 2024, we are making this Proxy Statement available on the Internet and are mailing the Notice to all stockholders entitled to vote at the Annual Meeting. We intend to mail or email this Proxy Statement, together with a proxy card, only to those stockholders entitled to vote at the Annual Meeting who have properly requested paper copies of such materials within three business days of request.
The only voting securities of Calix, Inc. are shares of common stock, $0.025 par value per share (“common stock”), of which there were 65,401,260 shares outstanding as of the Record Date. We need the holders of a majority of the outstanding shares of common stock, present or represented by proxy, to hold the Annual Meeting.
In this Proxy Statement, we refer to Calix, Inc. as the “Company,” “Calix,” “we” or “us” and the Board of Directors as the “Board.” When we refer to Calix’s fiscal year, we mean the year ended December 31 of the stated year.
Our 2023 Annual Report to Stockholders, which contains consolidated financial statements for fiscal year 2023, accompanies this Proxy Statement. Stockholders who received the Notice can access this Proxy Statement and the 2023 Annual Report to Stockholders at the website referred to in the Notice. You also may obtain a copy of our 2023 Annual Report, which was filed with the Securities and Exchange Commission (“SEC”), without charge, by writing to our Investor Relations department at the above address. Our 2023 Annual Report and Proxy Statement are also available under “Financials” in the Investor Relations section of our website at investor-relations.calix.com and at the SEC’s web site at www.sec.gov.

THE PROXY PROCESS AND STOCKHOLDER VOTING
QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING
Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on March 11, 2024, will be entitled to vote online at the Annual Meeting. At the close of business on March 11, 2024, there were 65,401,260 shares of common stock outstanding and entitled to vote.
For Shares Registered in Your Name
If, on March 11, 2024, your shares were registered directly in your name with Calix’s transfer agent, Computershare Inc., then you are a registered stockholder and will receive the proxy materials directly from Broadridge Financial Solutions, Inc. (“Broadridge”), an independent agent who we have engaged to tabulate votes for the Annual Meeting. You are the stockholder of record and may vote online at the Annual Meeting or vote by proxy. Whether or not you expect to attend, you should vote and submit your proxy over the Internet following the voting procedures described in the Notice to ensure that your vote is recorded. If you have requested and received paper copies of proxy materials, you can also vote over the phone or by signing, dating and returning by mail the proxy card sent to you.
For Shares Registered in the Name of a Broker, Bank or Other Agent
If, on March 11, 2024, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner of the shares, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also welcome to join the Annual Meeting and to vote online.
What do I need in order to be able to join the Annual Meeting online?
Any stockholder can join the Annual Meeting live online at www.virtualshareholdermeeting.com/CALX2024. The webcast will start at 10:45 a.m. Pacific Daylight Time. Stockholders may vote and submit questions while attending the Annual Meeting online. In order to be able to participate in the online Annual Meeting, you will need the control number included on your Notice or, if you received a printed copy of the proxy materials, your proxy card if you are a registered stockholder, or included with your voting instruction card and voting instructions you received from your broker, bank or other agent if you hold your shares in “street name.” Instructions on how to participate online are also posted online at www.virtualshareholdermeeting.com/CALX2024.
Why is Calix holding the Annual Meeting online?
Calix has held its annual meetings online since 2012. Among other reasons, Calix believes holding the Annual Meeting online enables broader stockholder attendance and participation from any location around the world, minimizing travel time and cost. In designing our online format, we have taken measures to facilitate easy access and to ensure our virtual meeting provides all stockholders with equal access to ask questions of our Board and management. Our virtual meeting allows participating stockholders to vote on proposals, access our Proxy Statement and 2023 Annual Report and engage in a live Q&A with our Board, management and auditors. In addition, a recording of our Annual Meeting is publicly available for a year following each annual meeting at www.virtualshareholdermeeting.com/CALX2024.
What am I being asked to vote on?
You are being asked to vote on:
election of two Class II directors to hold office until our 2027 Annual Meeting of Stockholders (Proposal No. 1);
approval, on a non-binding, advisory basis of the compensation of our named executive officers (“NEOs”) as disclosed in this Proxy Statement (Proposal No. 2); and
ratification of the selection of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024 (Proposal No. 3).
2

In addition, you are entitled to vote on any other matters that are properly brought before the Annual Meeting.
How does the Board recommend I vote on the Proposals?
The Board recommends that you vote:
FOR each of the Class II director nominees;
FOR approval, on a non-binding, advisory basis, of the compensation of our NEOs; and
FOR ratification of the selection of KPMG LLP as our independent registered public accounting firm.
How do I vote?
For election of directors, you may either vote “For” the two nominees or you may “Withhold” your vote for all or for any nominee you specify. For any other matter to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:
For Shares Registered in Your Name
If your shares are registered in your name, you may vote using any of the following methods:
To vote over the Internet prior to or during the Annual Meeting, follow the online instructions provided on the Notice.
To vote by phone, call the toll-free number found on the proxy card, which you can request by following the instructions provided on the Notice.
To vote by mail, follow the instructions provided on the Notice to request a proxy card and complete, sign and date the proxy card, and return it promptly by mail.
Whether or not you plan to join the Annual Meeting, we strongly encourage you to vote by Internet or phone to ensure that your vote is timely received and counted. You may still vote by mail if you do not have access to the Internet or a phone. As long as we receive your signed proxy card, or your vote by Internet or phone, by 11:59 p.m. Eastern Daylight Time on May 8, 2024, we will vote your shares as you direct. Even if you have submitted a proxy or voted by phone or the Internet before the Annual Meeting, you may still join the Annual Meeting and vote online. In such case, your previously submitted proxy or vote will be disregarded.
For Shares Registered in the Name of a Broker, Bank or Other Agent
If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should receive a voting instruction card and voting instructions with these proxy materials from that organization rather than from us. You should follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy card. You may also vote online at the Annual Meeting by following the voting instructions provided by your broker, bank or other agent to log in to www.virtualshareholdermeeting.com/CALX2024 and cast your vote. You should also complete and mail the voting instruction card to ensure that your vote is counted.
Who counts the votes?
We have engaged Broadridge as our independent agent to tabulate stockholder votes. If you are a registered stockholder and you choose to vote over the Internet (either prior to or during the Annual Meeting) or by phone, Broadridge will access and tabulate your vote electronically, and if you have requested and received proxy materials via mail or email and choose to sign and mail your proxy card, your executed proxy card is returned directly to Broadridge for tabulation. As noted above, if you hold your shares through a broker, your broker (or its agent for tabulating votes of shares held in “street name”) returns one proxy card to Broadridge on behalf of all its clients.
What is the required vote and how are votes counted?
A majority of the outstanding shares of common stock must be present or represented by proxy at the Annual Meeting in order to have a quorum. Abstentions and broker non-votes will be treated as shares present for the purpose of determining the presence of a quorum.
3

With respect to Proposal No. 1, the election of directors, directors will be elected by a plurality of the votes cast, which means that the two nominees receiving the highest number of “For” votes will be elected. Abstentions and broker non-votes will have no effect with regard to this proposal, because approval of a percentage of shares present or outstanding is not required for this proposal.
With respect to Proposals No. 2 and 3, the affirmative vote of the holders of a majority of the shares of common stock present or represented by proxy and entitled to vote on the proposal is required for approval. Abstentions have the same effect as a vote against these proposals.
Because your vote on Proposal No. 2 is advisory, it will not be binding on us, our Board or our Compensation Committee. However, we value our stockholders’ views on the effectiveness of our executive compensation program. Our Board and Compensation Committee consider the annual advisory vote of our stockholders and our stockholders’ views when making decisions about executive compensation.
Under the New York Stock Exchange (“NYSE”) rules, brokers are permitted to vote their clients’ proxies in their own discretion as to certain “routine” proposals. However, where a proposal is considered “non-routine,” a broker who has received no instructions from its client generally does not have discretion to vote its clients’ uninstructed shares on that proposal. When a broker indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, the missing votes are referred to as “broker non-votes.” Those shares would be considered present for purposes of determining whether a quorum is present but would not be counted in determining the number of votes present for the proposal. Those shares would not be taken into account in determining the outcome of a non-routine proposal.
Under NYSE rules, Proposals No. 1 and No. 2 are non-routine matters while Proposal No. 3 is a routine matter. Because brokers cannot vote uninstructed shares on behalf of their customers for non-routine matters, it is important that stockholders vote their shares.
How many votes do I have?
On each matter to be voted upon, you have one vote for each share of common stock you own as of March 11, 2024.
What if I return a proxy card but do not make specific choices?
If you have properly requested and received a proxy card by mail or email, and we receive a signed and dated proxy card that does not specify how your shares are to be voted, your shares will be voted “For” the election of each of the two nominees for director and “For” Proposals No. 2 and 3. If any other matter is properly presented at the Annual Meeting, the individuals named as proxy holders on your proxy card will vote your shares in the manner recommended by the Board on all proposals presented in this Proxy Statement and as they may determine in their best judgment as to any other matters properly presented for vote at the Annual Meeting.
Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors, officers and employees may also solicit proxies in person, by phone or by other means of communication. Directors, officers and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.
What does it mean if I receive more than one Notice or set of materials?
If you receive more than one Notice or more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must follow the instructions for voting on the Internet on all of the Notices or proxy cards you receive via mail or email upon your request, which includes voting over the Internet, phone or by signing and returning all of the proxy cards you request and receive.
Can I change my vote after submitting my proxy or voting on the Internet or by phone?
Yes. You can revoke your proxy or prior vote at any time before the final vote at the Annual Meeting. If you are the registered stockholder for your shares, you may revoke your proxy or prior vote in any one of three ways:
You may submit another properly completed proxy card with a later date or submit a new vote on the Internet or by phone using the same instructions followed when you submitted your prior vote.
4

You may send a written notice that you are revoking your proxy to Calix’s Corporate Secretary at Calix, Inc., 2777 Orchard Parkway, San Jose, California 95134, or corporate.secretary@calix.com.
You may join the Annual Meeting and vote online. Simply logging into the Annual Meeting will not, by itself, revoke your proxy or prior vote.
If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them, or you may join the Annual Meeting and vote online.
How will voting on any business not described in this Proxy Statement be conducted?
We are not aware of any business to be considered at the Annual Meeting other than the items described in this Proxy Statement. If any other matter is properly presented for vote at the Annual Meeting and you are not attending the meeting in person but have voted by proxy, the individuals named as proxy holder on your proxy card will vote your shares as they may determine in their best judgment.
When are stockholder proposals due for next year’s Annual Meeting?
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by November 28, 2024, to Calix’s Corporate Secretary at 2777 Orchard Parkway, San Jose, California 95134 or corporate.secretary@calix.com. If you wish to submit a proposal that is not to be included in next year’s proxy materials under the SEC’s stockholder proposal procedures or nominate a director, you must do so between January 9, 2025 and February 8, 2025; provided that if the date of the annual meeting is earlier than April 9, 2025 or later than July 8, 2025, you must give notice not later than the 90th day prior to the annual meeting date or, if later, the 10th day following the date on which public disclosure of the annual meeting date is first made. You are also advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. We intend to file a proxy statement and WHITE proxy card with the SEC in connection with our solicitation of proxies for our 2024 annual meeting. Stockholders may obtain our proxy statement (and any amendments and supplements thereto) and other documents as and when filed by Calix with the SEC without charge from the SEC’s website at: www.sec.gov.
What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority of the shares of common stock issued and outstanding and entitled to vote are present or represented by proxy at the Annual Meeting. On the Record Date, there were 65,401,260 shares outstanding and entitled to vote. Accordingly, 32,700,630 shares must be represented by stockholders present at the Annual Meeting or by proxy to have a quorum.
Your shares will be counted towards the quorum if you submit a valid proxy vote or vote online at the Annual Meeting. Abstentions and broker non-votes also will be counted towards the quorum requirement. If there is no quorum, either the chairperson of the Annual Meeting or a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present or represented by proxy, may adjourn the Annual Meeting to another time or place.
How can I find out the results of the voting at the Annual Meeting?
Voting results will be announced by the filing of a Current Report on Form 8-K within four business days after the Annual Meeting. If final voting results are unavailable at that time, we will file an amended Current Report on Form 8-K within four business days of the day the final results are available.

CORPORATE GOVERNANCE
Overview
Our Board is responsible for providing oversight over the Company’s business and affairs, including the Company’s strategic direction, as well as the management and financial and operational execution that can best perpetuate the success of the business and support the long-term interests of our stockholders. To effectively support its responsibilities, the Board has three principal board committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee that each carry out responsibilities set out in specific committee charters approved by the Board and consistent with applicable requirements of the NYSE and the SEC. The Board has also established a Cybersecurity Committee and a Strategic Committee, each with specific committee charters approved by the Board. The Board and each Board committee may at their discretion retain outside advisors at the Company’s expense in carrying out their responsibilities.
Our Board is committed to good corporate governance practices and seeks to represent stockholder interests through the exercise of sound judgment. To this end, the Board has adopted Corporate Governance Guidelines (“Guidelines”) that provide specific provisions for the governance of the Board and Company. We have a Code of Business Conduct and Ethics (“Code of Conduct”) applicable to all directors, officers and employees that is approved and adopted by our Board representing our commitment to the highest standards of ethics and integrity in the conduct of our business. Our bylaws, together with the Guidelines, the Board committee charters and our Code of Conduct serve as the governance and compliance framework of the Company.
On an annual basis, the Board and its committees review the Guidelines, Board committee charters and our Code of Conduct. The Guidelines, the written charter for each of the Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee, Cybersecurity Committee, Strategic Committee and the Code of Conduct, as well as any amendments from time to time, may be found under “Governance” in the Investor Relations section of our website at investor-relations.calix.com. The referenced information on the Investor Relations section of our website is not a part of this Proxy Statement.
Leadership Structure of the Board
Under our bylaws, our Board appoints our corporate officers, including the chief executive officer. Mr. Weening serves as president and chief executive officer and is responsible for setting the strategic direction for and the day-to-day leadership and performance of Calix. Mr. Russo, who previously served as chief executive officer until October 2022, has served as chairman of the Board of Directors since July 2021. Mr. Listwin, who previously served as chairman, has served as lead independent director since July 2021 and will serve in this capacity until the expiration of his term on May 9, 2024, the date of our 2024 Annual Meeting. Mr. Russo consults with Mr. Listwin and sets the agenda for Board meetings and presides over meetings of the full Board. Mr. Russo is not “independent” under the rules of the NYSE. Mr. Listwin is “independent” as defined under the rules of the NYSE and has significant executive leadership, strategic and operational experience including multiple executive leadership roles at large publicly-traded technology companies. The Board believes that the current board leadership structure is best for Calix and its stockholders at this time. Our Nominating and Corporate Governance Committee periodically reviews and recommends to the Board the leadership structure of the Board.
Board Independence
Among other considerations, the Board strongly values independent board oversight as an essential component of strong corporate performance. On at least an annual basis, the Board undertakes a review of the independence of each director and considers whether any director has a material relationship with Calix. The Board evaluates each director under the independence rules of the NYSE and the non-employee director and audit committee independence requirements of the SEC.

Seven of the total nine current directors of our Board are independent under NYSE rules:

(1)     Mr. Listwin will no longer serve on the Board nor any committee of the Board upon the expiration of his term on May 9, 2024.
The NYSE rules require listed company boards have at least a majority of independent directors. Based on its evaluation, our Board determined that each of Messrs. Bowick, Listwin, Mukherjee and Peters, each of Mses. Crusco, Fields and Makagon, representing seven of Calix’s nine current directors, are independent directors as defined under the NYSE rules. Mr. Russo, our chairman, and Mr. Weening, our president and chief executive officer, are the only members of the Board who are not independent.
Board Composition and Qualifications
The Board assesses Board composition and qualifications at least annually. In assessing Board composition and qualifications, as well as in evaluating candidates for nomination or to fill vacancies on the Board, the Board seeks to maximize effectiveness of the Board and its committees to perpetuate the success of the Company, to best represent stockholder interests through the exercise of sound judgment and to assure continuity in the Board’s oversight over the Company and management. The Board places significant emphasis on ensuring an appropriate mix of characteristics, skills and experience for the Board as a whole and as to each individual director. The Board has delegated the evaluation of the skills and attributes of the Board as a whole and each individual director against the Company’s needs and strategic direction to the Nominating and Corporate Governance Committee pursuant to the committee’s charter. Among other considerations, the Board seeks to ensure an appropriate mix of expertise in executive and corporate leadership, diversity of background, perspective and experience (including diversity of gender, age and race/ethnicity), personal and professional integrity, ethics and values, financial and operational experience, depth of knowledge related to our business, business risks and operations, as well as expertise and insights in technologies, industries and markets relevant to our strategic plans, as set forth in our Corporate Governance Guidelines.
Our Board believes the current mix of skills, backgrounds, service period and attributes of our Board maximizes the effectiveness of our Board in its oversight responsibilities. In 2017, Mses. Makagon and Crusco joined our Board, with Ms. Makagon bringing substantial expertise in global platform strategy, technology, cybersecurity, operations and high-technology executive leadership and Ms. Crusco adding deep financial, accounting and operational expertise, public company leadership and governance experience. In 2022, Mr. Mukherjee joined our Board, bringing expertise in cloud software products, top-tier talent acquisition and small business solutions. More recently, in 2023, Ms. Fields joined our Board, bringing expertise in cloud software product and ecosystem development. The Board values the added diversity of gender, age, ethnicity, experience and perspective with the additions to the Board of Mses. Crusco, Fields and Makagon and Mr. Mukherjee and continues to include diversity in its assessment of Board composition and qualifications. Our Board also considers board tenure and mix of shorter, medium and longer tenure of board service in its review of Board composition. The average tenure of our independent directors is approximately seven years.

Board Meetings and Committees
Our Board met six times during fiscal year 2023. During 2023, each Board member attended 75% or more of the total number of meetings of the Board and of the committees on which he or she served.

We encourage our directors to attend our annual meetings of stockholders, and all of our directors attended our 2023 annual meeting of stockholders.

Our Board has determined that Ms. Crusco and Mr. Peters are each an “audit committee financial expert” as defined under the SEC rules and that Ms. Crusco’s service on the audit committee of one other public company would not impair her ability to effectively serve on our Audit Committee.

The Nominating and Corporate Governance Committee may take into account minimum qualifications including, among other factors the Committee may deem appropriate: diversity of personal and professional background, perspective and experience, including diversity of gender, age and ethnicity; personal and professional integrity, ethics and values; executive experience in corporate management, operations, governance or finance; experience relevant to the Company’s business and industry and with relevant social policy considerations; experience as a board member or executive officer of other publicly-held companies; relevant academic expertise; practical and mature business judgment; promotion of a diversity of business or career experience relevant to the success of the Company; and any other relevant qualifications, attributes or skills, which will be evaluated in the context of the Board as a whole, with the objective of assembling a board that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In addition, the Nominating and Corporate Governance Committee expects any candidate for the Board to be able to represent the interests of the Company’s stockholders as a whole rather than any special interest or constituency.
Each of our nominees standing for election at this 2024 Annual Meeting was recommended to the Board by the Nominating and Corporate Governance Committee based on the Committee’s evaluation as set forth above.
The policy of the Nominating and Corporate Governance Committee is to consider properly submitted director candidates recommended by stockholders.

The presiding officer at the applicable annual meeting may, if the facts warrant, determine
10

that a nomination was not properly made in accordance with the foregoing and our bylaws, in which case the defective nomination may be disregarded. 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 Calix’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 12, 2024.

The chairman of the Board leads discussions and actions related to the self-assessments. The Board is committed to ongoing director education and advancement. To that end, the Company has a written Board education policy and provides its directors with membership in the National Association of Corporate Directors (“NACD”) to assist them in remaining current with best practices and developments in board oversight and corporate governance, as well as opportunities to participate in NACD fellowship programs on leading boardroom practices and commitment to boardroom excellence.

Board Oversight Over Risks
The Board has an active role, as a whole and also at the committee level, in overseeing management of Calix’s risks, including financial risks, cybersecurity risks, credit and liquidity risks, legal and regulatory risks and operational risks, including risks that may impact continuity of our business in the event of disruptions or disasters that may materially impact our business. The Board is responsible for general oversight of risks and regularly reviews information from management who is responsible for the day-to-day processes and operations to manage and mitigate risks.
The Audit Committee has primary responsibility for oversight over management’s processes over financial, credit and liquidity, legal and regulatory risks, including the Company’s compliance program; the Compensation Committee is responsible for risk assessments over Calix’s compensation practices and policies, including incentivizing and retention of executive officers; the Nominating and Corporate Governance Committee oversees corporate governance and management of our ESG and public company governance risks; the Cybersecurity Committee oversees Calix’s overall business continuity and disaster recovery, including management of risks associated with cybersecurity, privacy and data breach threats; and the Strategic Committee has oversight over internal and external risks to our strategic plan. While Board committees have responsibility for evaluating certain areas of risks and overseeing the management of such risks, the entire Board retains overall responsibility and remains regularly informed through committee reports about such risks.
Code of Conduct and Compliance
We are committed to the conduct of our business to the highest standards of ethics and integrity as reflected in our Code of Conduct. All of our directors, officers and employees annually review our Code of Conduct and are expected to comply with our Code of Conduct, including our principal executive officer, principal financial officer, principal accounting officer and persons performing similar functions. Under our Code of Conduct, we have established a compliance hotline that is operated by an independent third party to receive complaints about any accounting, internal control or auditing matters as well as compliance, ethical or other matters of concern (including on an anonymous basis where permitted under applicable law). Annually, our Audit Committee reviews our Code of Conduct and related policies and processes with management. Our Code of Conduct is available under “Governance” in the Investor Relations section of our website at investor-relations.calix.com.
Risk Assessment of Compensation Practices and Policies
We have assessed, with input from outside consultants, and discussed with the Compensation Committee our compensation policies and practices for our employees as they relate to risk management. Based upon this assessment, we believe that any risks arising from such policies and practices are not reasonably likely to have a material adverse effect on the Company.
Our employees’ base salaries are fixed in amount and thus we do not believe that they encourage excessive risk-taking. While performance-based cash incentives and sales-based incentives focus on achievement of short-term or annual goals, we believe that our performance-based cash incentives and sales-based incentives appropriately balance risk and the desire to focus employees on specific goals important to our growth and long-term success. We believe these programs also do not encourage unnecessary or excessive risk taking as the potential payout is limited, with payouts on performance-based cash incentives for our executives generally limited to 100% of target and payouts of greater than target based on limited incremental achievement above 100% of target. Further, such programs represent only one portion of the total compensation opportunities available to most employees, and we believe that our internal policies and controls help mitigate this risk. Employees are also given the opportunity to participate in stock ownership through our employee stock purchase plans to purchase stock at discounted prices, subject to limits and holding periods stated in the plans, which we believe help align employee performance with creation of long-term stockholder value.
A significant portion of the compensation provided to senior management is in the form of long-term equity-based incentives that are conditioned on achievement of one or more annual financial performance targets that we believe are important to help further align management’s interests with those of our stockholders. We do not believe that these equity-based incentives encourage unnecessary or excessive risk taking because their ultimate value is tied to our financial performance and stock price and vesting of such equity awards are generally over a four-year period.
The statements regarding the risks arising from our compensation policies and practices contain forward-looking statements that involve substantial risks and uncertainties. We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs.

PROPOSAL NO. 1
ELECTION OF DIRECTORS
Our Amended and Restated Certificate of Incorporation provides that our Board shall be divided into three classes, with the directors in each class having a three-year term. Unless the Board determines that vacancies (including vacancies created by increases in the number of directors) shall be filled by the stockholders, and except as otherwise provided by law, vacancies on the Board may be filled only by the affirmative vote of a majority of the remaining directors. A director elected by the Board to fill a vacancy (including a vacancy created by an increase in the number of directors) shall hold office until the next election of the class for which such director shall have been chosen.
As of March 28, 2024, the date this Proxy Statement is made available, the Board consists of nine directors, divided into the following three classes:
Class I directors: Kathy Crusco, Carl Russo and Michael Weening, whose current terms will expire at the 2026 Annual Meeting;
Class II directors: Don Listwin, Rajatish Mukherjee and Kevin Peters, whose current terms will expire at the 2024 Annual Meeting; and
Class III directors: Christopher Bowick, Eleanor Fields and Kira Makagon, whose current terms will expire at the 2025 Annual Meeting.
We received notice on March 22, 2024, that one of our independent directors, Mr. Listwin, had decided not to stand for re-election upon the expiration of his term on May 9, 2024, the date of our 2024 Annual Meeting. Mr. Listwin indicated that this decision not to stand for re-election was not due to any disagreement with the Company nor any matter relating to the Company’s operations, policies or practices. Our Board unanimously voted on March 22, 2024, to reduce the size of our Board from nine members to eight, effective upon the expiration or earlier termination of Mr. Listwin's term on the Board. Mr. Listwin is a Class II director, whose current term expires at the 2024 Annual Meeting. Our Board plans to reevaluate membership on, and leadership of, each of the Board committees in light of the expiration of Mr. Listwin's term, including considering the appointment of a successor as lead independent director.
Our Nominating and Corporate Governance Committee has recommended, and our Board has approved, Rajatish Mukherjee and Kevin Peters as nominees for reelection as Class II directors at the 2024 Annual Meeting. Mr. Mukherjee and Mr. Peters have each agreed to stand for reelection as Class II directors. Each director to be elected will hold office from the date of such director’s election by the stockholders until the third subsequent annual meeting of stockholders or until his successor is elected and has been qualified, or until such director’s earlier death, resignation or removal. Shares of common stock represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two Class II director nominees named above.
The Board expects each of the nominees to be available for election to the Board at the 2024 Annual Meeting. In the event that any nominee should be unable to serve or for good cause will not serve, such shares will be voted for the election of such substitute nominee as the Board may propose. Each person nominated for election has agreed to serve if elected, and management has no reason to believe that any nominee will be unable to serve. Directors are elected by a plurality of the votes cast at the meeting.
Our Director Nominees and Board of Directors
At least annually our Nominating and Corporate Governance Committee reviews the skills and characteristics of directors and the mix of skills and experience and diversity of the Board in the context of our business strategy, growth initiatives and our customers and target market, our business and operating requirements and the long-term interests of our stockholders. In doing so, the Nominating and Corporate Governance Committee seeks a board composition that can best perpetuate the success of the business and represent stockholder interests. The Committee also considers the tenure of our directors and seeks to maintain a balance of longer tenured directors with deep institutional knowledge and newer directors who bring new perspectives to the Board. See “Board Meetings and Committees — Nominating and Corporate Governance Committee” above regarding the Nominating and Corporate Governance Committee’s evaluation and selection of director nominees.
The Board believes that all the nominees for election are highly qualified and have the skills and experience required for effective service on the Board. Mr. Mukherjee serves on our Compensation Committee and Cybersecurity Committee, and brings substantial expertise and knowledge regarding compensation, cybersecurity, privacy and software platform technologies. Mr. Peters chairs our Cybersecurity Committee and serves on our Audit Committee as our audit committee

Independence of the Board
The NYSE prescribes independence standards for listed companies. These standards require a majority of the Board to be independent. They also require each member of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee of the Board to be independent. No director qualifies as independent unless the Board determines that the director has no direct or indirect material relationship with us. The Board also evaluates each director’s independence to serve on our Board and committees under the applicable requirements of the SEC. On an annual basis, each director and executive officer is obligated to complete a director and officer questionnaire which requires disclosure of any transactions with us in which the director or executive officer, or any member of his or her immediate family, have a direct or indirect material interest. We also review our relationship with any entity employing a director or on which the director currently serves as a member of the board. After review of all relevant transactions or relationships between each director, or any of his or her immediate family members, and Calix, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that all of Calix’s current directors are independent directors within the meaning of the applicable NYSE standards, except for Mr. Russo, Calix’s chairman, and Mr. Weening, Calix's president and chief executive officer. All of the committees of our Board are comprised entirely of directors determined by the Board to be independent within the meaning of the NYSE standards and applicable SEC regulations.

PROPOSAL NO. 2
APPROVAL ON A NON-BINDING, ADVISORY BASIS OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS (“SAY-ON-PAY”)
We are seeking an advisory vote from our stockholders to approve the compensation paid to our NEOs, as disclosed in this Proxy Statement under the “Compensation Discussion and Analysis” section (“CD&A”) below.
Our Compensation Committee, with advice and information from its external compensation consultant and consideration of recommendations by our CEO for our executives (other than the CEO), has structured our executive compensation program to stress a pay-for-performance philosophy. The compensation opportunities provided to our NEOs are significantly dependent on Calix’s financial performance, the performance of Calix’s stock and the NEO’s individual performance, which are intended to drive creation of sustainable stockholder value. The Compensation Committee intends to continue to emphasize what it believes to be responsible compensation arrangements that attract and retain high-caliber executive officers and motivate strong performance to achieve Calix’s short- and long-term business strategies and objectives.
Our Board previously determined to hold an advisory “say-on-pay” vote every year. In accordance with this determination and Section 14A of the Exchange Act, you have the opportunity to vote “For” or “Against” or to “Abstain” from voting on the following non-binding resolution relating to executive compensation:
“RESOLVED, that the stockholders approve, on an advisory basis, the compensation paid to Calix’s NEOs as disclosed in Calix’s proxy statement for the 2024 Annual Meeting of Stockholders under the compensation disclosure rules of the SEC, including the compensation discussion and analysis, compensation tables and narrative discussion of the proxy statement.”
In deciding how to vote on this proposal, we encourage you to consider Calix’s executive compensation philosophy and objectives, the design principles and the elements of Calix’s executive compensation program described in our CD&A below. As described in the CD&A, a guiding principle of our compensation philosophy is that pay should be linked to performance and that the interests of our executives and stockholders should be aligned. Our compensation program is a mix of short- and long-term components, cash and equity elements and fixed and contingent payments in proportions we believe will provide the proper incentives, reward our NEOs, help us achieve our goals and increase stockholder value. For example:
NEOs Compensation Aligned with Stockholder Interests and Substantially Tied to Company Performance. A significant portion of our NEOs' compensation is tied to performance in the form of variable cash and performance-contingent stock options earned based on stated performance targets tied to achievement of growth in Calix’s stock price and Calix’s quarterly and annual financial performance along with consideration of an individual executive's performance. From time to time, our Compensation Committee may choose to award our NEOs with other vehicles to assist with retention or to further align pay and performance, including time-based option grants.
Change in Control and Severance Benefits Not Grossed Up. Calix provides limited change in control and severance benefits to provide NEOs security and to remain competitive in attracting and retaining executive talent. Calix does not provide for any tax gross up to any NEO in connection with any change in control or severance benefits.
Clawback Policies. Calix adopted a clawback policy in May 2019 that applies to all executive officers and covers all compensation under our cash incentive programs as well as all equity awards granted or awarded after the date the policy was adopted. The policy applies in the event our financial statements are restated as a result of material non-compliance with financial reporting rules as defined in the policy and provides our Board with broad discretion as to the actions that may be taken based on circumstances leading to the restatement, including recovery of incentive-based compensation received by an executive officer in excess of what the executive officer would have been paid under the restatement. In November 2023, we adopted a second clawback policy that applies to our executive officers and covers all compensation under our cash incentive programs as well as all equity awards granted or awarded after the date the policy was adopted, in compliance with the SEC’s adoption of new rules to implement Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as implemented by NYSE. The policy applies in the event our financial statements are restated as a result of material non-compliance with financial reporting rules as defined in the policy and provides our Board with broad discretion as to the actions that may be taken based on circumstances leading to the restatement, including recovery of incentive-based compensation received by an executive officer in excess of what the executive officer would have been paid under the restatement.
24

Two-Year Holding Period Upon Exercise of Certain Time-Based Option Grants. In November 2019, Mr. Sindelar and Mr. Weening were awarded time-based option grants annually over a five-year period as discussed under “Compensation Discussion and Analysis – Letter Agreements for Cory Sindelar and Michael Weening” below. Each option grant will vest and become exercisable over four years, and any shares issued upon exercise of the options are further subject to a two-year holding period from the vest date of such shares to further align our NEOs’ long-term equity compensation with the Company’s efforts to improve financial performance over the long-term.
To be approved, on a non-binding and advisory basis, the compensation paid to our NEOs must receive a “For” vote from the holders of a majority in voting power of the shares of common stock which are present or represented by proxy and entitled to vote on the proposal. Abstentions will have the same effect as “Against” votes for purposes of determining whether this matter has been approved. Broker non-votes will not be counted for any purpose in determining whether this matter has been approved.
While your vote on this proposal is advisory and will not be binding, we value the opinions of Calix’s stockholders on executive compensation matters and will take the results of this advisory vote into consideration when making future decisions regarding Calix’s executive compensation program. Unless the Board modifies its determination of the frequency of future “say on pay” advisory votes, the next “say-on-pay” advisory vote will be held at our 2024 Annual Meeting of stockholders.
THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE COMPENSATION PAID TO THE NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT UNDER THE COMPENSATION DISCLOSURE RULES OF THE SEC.

PROPOSAL NO. 3
RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Our Audit Committee has engaged KPMG LLP (“KPMG”) as our independent registered public accounting firm for the fiscal year ending December 31, 2024, and is seeking ratification of such selection by our stockholders at the 2024 Annual Meeting. KPMG has audited our financial statements since February 29, 2016. Representatives of KPMG are expected to be present at the 2024 Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG as our independent registered public accounting firm. However, our Audit Committee is submitting the selection of KPMG to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain KPMG. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Calix and its stockholders.
To be approved, the ratification of the selection of KPMG as our independent registered public accounting firm must receive a “For” vote from the holders of a majority in voting power of the shares of common stock which are present or represented by proxy and entitled to vote on the proposal. Abstentions will have the same effect as an “Against” vote for purposes of determining whether this matter has been approved. Broker non-votes will not be counted for any purpose in determining whether this matter has been approved.

EXECUTIVE COMPENSATION
Compensation Discussion and Analysis
The following Compensation Discussion and Analysis (“CD&A”) describes and discusses our objectives and policies as well as the material components of our compensation program for our NEOs. For 2023, our NEOs were:
Michael Weening, president and chief executive officer, our “CEO”
Cory Sindelar, chief financial officer, our “CFO”
J. Matthew Collins, chief commercial operations officer, our “CCOO”
Shane Eleniak, chief product officer, our “CPO”
Executive Summary
Calix develops, markets and sells leading platform (cloud, software and systems) and managed services that enable broadband service providers, or BSPs, of all types and sizes to innovate and transform their businesses. Our platform, which includes Calix Cloud, Revenue EDGE and Intelligent Access EDGE, gathers, analyzes and applies machine learning to deliver real-time insights seamlessly to each key business function. Our customers utilize this data and insights to simplify network operations, marketing and customer support and deliver a growing portfolio of SmartLife managed services and experiences that excite their subscribers. This enables BSPs, to grow their brand through increased subscriber acquisition, loyalty and revenue and to reduce their operating costs, creating value for their businesses and the communities they serve.
Our mission is to enable BSPs of all sizes to simplify, excite and grow.
Our compensation and benefits programs reflect our philosophy of compensating and incentivizing all our employees, including our NEOs, in ways that support two primary objectives:
identify and reward outstanding performance that reflects Calix principles, mission and values and aligns with long-term stockholder value creation; and
attract, reward and retain exceptional talent in the markets in which we operate.
To help us achieve these objectives, a significant portion of our NEOs’ compensation is “at risk” with significant upside potential for strong performance as well as downside exposure for underperformance. NEOs with greater responsibilities and ability to directly impact our Company’s goals and long-term results bear a greater proportion of the risk if these goals and results are not achieved.

The Calix team closed out 2023 with continued deliberate and disciplined execution, delivering record revenue and non-GAAP gross margin. The most notable achievement of 2023 remained the growth of our platform, cloud and managed services business. It drives the value and competitive advantage for our BSP customers and in turn for Calix. This value creation is clearly reflected in our gross margin expansion. Since the pandemic induced low of 50.1% (GAAP gross margin of 49.6%), non-GAAP gross margin has expanded by 400 basis points to 54.1% (GAAP gross margin of 42.8%) in the fourth quarter of 2023. Moreover, the visibility that we have into our customers’ plans from our direct relationships and cloud data has enabled us to manage through these last several challenging years in a disciplined manner. In sum, we have achieved four years of record growth based on the strength of our unique platform, cloud and managed services model for BSPs. A summary of our financial results over the past four years is shown below.

Compensation Philosophy and Process
Our goal is to attract and retain highly qualified executives to manage and oversee each business function. We strive to find the best talent that will be able to contribute to our long-term success, culture, principles, mission and values and who will promote the long-term interests and growth of our Company. Our compensation philosophy is intended to promote a team-oriented approach as a portion of each NEO’s incentive compensation is based on achievement against the same performance objectives as our broad-based incentive plan.
The objectives of our executive compensation program are to:
enable us to attract, retain and drive a high caliber, talented leadership team to execute on our business strategy;
foster a goal-oriented leadership team with a clear understanding of long-term business objectives and shared corporate principles and values that aligns with our mission;
ensure that the elements of compensation provided to our employees and executives are balanced and do not encourage excessive risk-taking;
reflect the competitive environment of our industry and our changing business needs;
create strong alignment with our shareholders;
allocate our resources effectively and efficiently in the development and selling of market-leading platforms, systems and services; and
maintain pay parity and fair compensation practices across our organization.
1.jpg
The objectives inform our compensation philosophy to:
be market competitive;
emphasize pay for performance;
share risks and rewards with our stockholders; and
reflect our principles, mission, and values.
1.jpg
To achieve our objectives, we provide the following compensation elements to our NEOs:
base salary;
incentive-based cash compensation;
grants of long-term equity awards; and
health, welfare and retirement benefits.
Role of Our Compensation Committee
Our Compensation Committee approves our executive compensation and all executive benefit plans and policies. The Compensation Committee is appointed by the Board and consists entirely of directors who are non-employee directors and independent for purposes of Rule 16b-3 of the Exchange Act. In 2023, our Compensation Committee approved the compensation for all of our NEOs. Our CEO assesses NEO individual performance and compensation, excluding his own performance and compensation, each year and makes recommendations regarding each element of NEO compensation to the Compensation Committee. The Compensation Committee evaluates the performance of the CEO and determines and approves his compensation based on this evaluation. The Compensation Committee also has oversight of senior management pay and the effectiveness of our executive compensation and benefits programs.
28

In 2023, the Compensation Committee retained the services of Compensation Advisory Partners LLC (“CAP”), an independent compensation consultant, who worked with management only at our Compensation Committee’s direction to interpret results, make recommendations and assist in setting compensation levels for our executive officers. Our Compensation Committee annually assesses the independence of its executive compensation advisor. The Compensation Committee determined that CAP is independent and that there is no conflict of interest in retaining their services.
How we set executive compensation for our NEOs
Competitive Market Review
Our Compensation Committee determines pay for our NEOs in large part based upon its assessment of competitive market data and individual executive roles and responsibilities to pursue our short and long-term strategy. In setting executive pay for 2023, our Compensation Committee reviewed our NEOs’ compensation, as well as the mix of elements used, and compared that information with data provided by CAP. Based on its review, the Compensation Committee concluded that our programs support our objectives while considering market practice.
Peer Group
We operate in a highly competitive market for talent. We strive to attract and retain highly qualified executives to effectively lead each of our business functions to achieve our business strategy. In doing so, we draw upon a pool of talent that is highly sought after by large and established technology and telecommunications companies and by other competitive companies in development or growth phases. We also compete for key talent on the basis of our vision of future success, our culture and values, the cohesiveness and productivity of our teams and the excellence of our technical and leadership teams.
To gain perspective on market practices as well as competitive pay levels, the Committee utilizes compensation data from a peer group. Our peer group criteria consisted of companies within the technology industry, with an increasing shift toward software and platform companies, and reflective of our size.
Each year, we review our peer group to ensure that the companies continue to be relevant from an industry and size perspective. In 2022, we made changes to our peer group to reflect our continued transition to a platform and managed services company as well as our revenue growth in the past three years. Below is the peer group approved by our Compensation Committee in 2022 that was used to establish and evaluate the 2023 compensation program for our NEOs:
 8x8, Inc.
Infinera Corp.
ADTRAN
 InterDigital
Arista Networks, Inc.*
 LiveRamp Holdings
 Blackbaud
 NETGEAR
Box, Inc.*
NetScout Systems, Inc.
Casa Systems, Inc.
Nutanix
Commvault Systems, Inc.*
Rapid7, Inc,*
Extreme Networks, Inc.
Ribbon Communications US LLC
Five9, Inc.*
Varonis Systems
 Harmonic
Viavi Solutions
* Reflects additions to our peer group for determining 2023 compensation.
At the time our peer group companies were determined, revenue for the peer companies ranged from $360 million to $3.2 billion and market capitalization ranged from approximately $370 million to $29 billion; our annual revenue and market capitalization were positioned at the 55th percentile and 50th percentile, respectively. The Compensation Committee reviews peer group information when making its compensation decisions, including target annual cash compensation, which includes base salary and target annual incentive opportunity; and total direct compensation ("TDC"), which includes target annual cash compensation and equity compensation. Our Compensation Committee does not target a specific percentile for pay; however, the Compensation Committee uses the median of the peer group as a key reference point for target annual cash compensation, while considering a wider range for long-term incentives recognizing our core long-term incentive is comprised entirely of performance-contingent stock options which are completely at risk.
29

2023 Total Direct Compensation
We provide annual compensation to our NEOs that is intended to be market competitive, support our compensation philosophy, focus on long-term profitable growth and align the interests of our executives with the interests of our stockholders. To that end, we provide our executives with base salary, cash incentive bonus and performance-contingent stock options and in select cases service-based stock options.
A significant amount of the total potential annual compensation of our other NEOs in 2023 is comprised of “at-risk” variable compensation based on our achievements of corporate financial targets aligned with our business strategy and creating value for our stockholders. Consistent with the compensation philosophy, total pay for our NEOs is heavily weighted towards long-term equity awards which, other than limited service-based options described below, are comprised 100% of performance-contingent stock options which only deliver value if the stock price increases and our NEOs have achieved additional financial performance goals. The weighting of compensation elements for Mr. Weening, our CEO, and our other NEOs, in 2023, as a group, is as follows:
https://cdn.kscope.io/4ba6065f2bca6cb9379fbca7a27d3884-PayMix Color 02 Half.jpg
For the purposes of the graphs above, base salary and bonus reflect values disclosed in the Summary Compensation Table and long-term equity is based on grant date fair value of the annual performance-contingent stock option awards granted. The graphs do not include service-based options granted to Messrs. Sindelar and Weening in November 2023, pursuant to letter agreements entered into with them, since the options granted under those letter agreements are not part of their on-going compensation.
From time to time, we grant our executives, including our NEOs, service-based stock options. These awards are granted at time of hire, in connection with a promotion and, in limited circumstances, to retain key talent. Due to their potential as future leaders of the Company and the desire to retain them, in 2019 the Compensation Committee approved, and we entered into, five-year letter agreements with each of Mr. Weening (“Weening Letter Agreement”) and Mr. Sindelar ("Sindelar Letter Agreement") that provided for yearly grants of service-based stock options over the length of the agreement. The Compensation Committee believed it was in the best interest of the Company to retain these executives to deliver on the future of Calix as well as align their interests with that of our stockholders. In 2023, we granted each of Mr. Weening and Mr. Sindelar an option to purchase 120,000 and 100,000 shares of our common stock pursuant to their letter agreements. These were the final grants to Messrs. Weening and Sindelar under their letter agreements. We do not anticipate entering into a similar agreement going forward that guarantees specific long-term incentive grants over a multi-year period.
Salary
Calix offers base salaries that are competitive with our peers and reflect the experience, skills, knowledge, responsibilities and performance of each NEO. The Compensation Committee reviews the base salaries of our NEOs at least once a year.
The table below sets forth the annual base salary as of December 31, 2023 for each NEO as set by our Compensation Committee. In 2023, the Committee recognizing the performance of Messrs. Sindelar, Collins and Eleniak and that their salary market position was generally below the 25th percentiles of the market, approved performance and market-based increases which would better position these NEOs relative to our compensation philosophy. These promotion increases
30

were effective in February 2023. Mr. Weening received a salary increase at the time of his promotion to CEO in September 2022 and did not receive an increase in 2023.

Cash Incentive Compensation
2023 Executive Cash Incentive Plan Design
Our executives, including our NEOs, participate in two separate cash bonus programs under the executive cash incentive plan. We believe these programs focus our executives on our long-term profitable growth strategy while recognizing the challenges with predicting performance in this high-growth environment. A portion of the executive cash incentive plan payout for our executives is based on the Company’s achievement against preset quarterly revenue and non-GAAP operating income targets. For 2023, we added an annual component that would provide a payout if we met certain revenue targets and exceeded operating income targets. The other portion of the executive cash incentive plan payout is based on non-GAAP gross margin which provides an incremental opportunity that is based on our achievement above a minimum non-GAAP gross margin target, measured quarterly. The combined cash bonus programs include an assessment of the NEO's individual performance for the year. Our executive cash incentive plan does not provide for any guaranteed payments and there is no payout if we do not achieve a pre-established level of threshold performance.
In setting the performance measures and targets for our executive cash incentive plan, our Compensation Committee seeks to align the performance targets to our key financial objectives and business strategy, which we believe furthers the long-term interests of our stockholders. The performance targets are designed to incentivize financial growth and performance over the year as we continue to drive adoption of our cloud and software platforms. In 2023, our Compensation Committee established our quarterly and annual corporate financial targets based on the annual operating plan approved by our Board at the beginning of the year and based on quarterly financial information prepared by management. As discussed in more details under "2023 Executive Cash Incentive Plan Achievement", our Compensation Committee approved a reduction in our annual performance goals to align with the lower budgets in our annual operating plan and to reflect the challenges in setting annual goals in a high-growth environment.
31

The following chart summarizes key features of our 2023 executive cash incentive plan.
Bonus ComponentDescription
Revenue / Non-GAAP Operating Income (1)
Component has a quarterly metric and, for 2023, an annual metric;
Quarterly metric is capped at target (i.e., no upside) and based on pre-established revenue (50%) and non-GAAP operating income (50%) goals;
Annual metric allows participants to earn up to an additional 50% of target payout if the revenue target is met and non-GAAP operating income is exceeded;
Both revenue and non-GAAP operating income thresholds must be achieved for any quarterly metric to be funded; and
 The plan is intended to drive focus on delivering on the business plan which aligns with long-term value creation.
Non-GAAP Gross Margin (2)
Participants can earn incremental compensation as gross margin improves, which we believe focuses our NEOs on profitable growth, which is critical;
 Specifically, the plan is funded based on 25% of the gross margin dollars that exceed target (on a quarterly basis). If our non-GAAP gross margin is at or below the quarterly target, the bonus is not funded; and
The resulting pool is allocated to participants based on base salary.
(1)Non-GAAP operating income for the purposes of the executive cash incentive plan is calculated as operating income on a GAAP basis less certain items that are not considered indicative of our performance, consisting of: stock-based compensation, intangible asset amortization and inventory and component liability charges. Reconciliation is provided in Appendix A.
(2)Non-GAAP gross margin for the purposes of the executive cash incentive plan is calculated as gross margin on a GAAP basis less certain items that are not considered indicative of our performance, consisting of: stock-based compensation, intangible asset amortization and inventory and component liability charges. Reconciliation is provided in Appendix A.
Total Executive Cash Incentive Plan Opportunity
The 2023 executive cash incentive plan opportunity as a percentage of base salary for the quarterly and annual revenue and non-GAAP operating income as set by our Compensation Committee for each of our NEOs is listed in the table below. The payout for our second cash bonus component (the non-GAAP gross margin component) is allocated to participants, including our NEOs, based on a proportional amount of the funded pool once performance has been determined. Therefore, participants do not have a target opportunity similar to our other component.

Once the cash incentive pool is funded, our Compensation Committee retains discretion to adjust cash incentive compensation paid to each individual up or down, ranging from 50% to 200% of the funded amounts for each individual’s executive cash incentive plan opportunity for the year, based upon assessment of individual performance. Our CEO provides his assessment of individual NEO performance for our Compensation Committee’s determination of actual cash incentive payout of amounts funded under the plan. Our CEO’s performance is evaluated and determined solely by our Compensation Committee.

2023 Executive Cash Incentive Plan Achievement
The table below sets forth the quarterly financial targets and achievement applicable to the two separately funded cash bonus opportunities under our cash incentive plan for each fiscal quarter of 2023. For the first bonus opportunity, full 100% funding of target bonuses was achieved in each of the four quarters as quarterly revenue and non-GAAP operating income was at or above target for such quarters. For the second bonus opportunity, our non-GAAP gross margin exceeded the target in the second, third and fourth quarters. However, non-GAAP gross margin was below target in the first quarter which resulted in no funding for this quarter.

The annual portion of our executive cash incentive plan funds if we met our annual revenue goal and exceeded our non-GAAP operating income. In February, our Compensation Committee approved revenue and non-GAAP operating income goals that were based on our annual operating plan. At that time, the target revenue goal was $1,100 million and the non-GAAP operating income goal was $135 million. In June 2023, the Company lowered financial targets on the annual operating plan, which was approved by the Board, and the Compensation Committee approved a reduction in the annual goals to align with the Company’s revised annual budget. The revenue target was reduced to $1,050 million and the non-GAAP operating income was reduced to $115 million. Given the challenges of setting annual goals in a post-pandemic environment with supply-chain normalization and the aggressiveness of the targets that were set, the Compensation Committee reviewed the revenue goal and decided to further reduce the annual revenue goal to $1,042 million in August 2023. The table below outlines the financial targets and achievement for the annual incentive component:

Annual Revenue/Non-GAAP Operating Income Goals

Revenue
(in millions)
Non-GAAP Operating Income
(in millions)
Target$1,042.0 $115.0 
Actual
$1,039.6 $123.0 

Management exceeded the non-GAAP operating income target, but was below the annual revenue target. The Compensation Committee reviewed Calix’s overall financial performance in 2023 and recognizing the record level of operating income (24% growth) and revenue (26% growth), decided to waive the revenue requirement and funded the incentive plan based on the operating income achievement. As a result, our executives, including the NEOs, earned 34.5% of the payout opportunity for exceeding the non-GAAP operating income goal. The committee believes these payouts were appropriate given the current environment and the challenges with predicting performance. As we discuss in further detail in “Say on Pay” section, for 2024 and beyond, we are incorporating a mechanism such that the Compensation Committee can adjust payouts up or down by up to 20% to mitigate the need to adjust goals in the future.
The payout awards of funded cash incentive amounts are determined by our Compensation Committee following assessment of performance and in consultation with the chief executive officer as to each NEO other than himself. For 2023, each NEO was awarded 100% of his funded opportunity under the executive cash incentive plan.

Equity-Based Incentives
Our 2019 Plan provides our key employees, including our NEOs, with stock-based incentives to align their interests with the interests of our stockholders. We grant 100% of our equity compensation in the form of stock options because we believe they provide the greatest alignment with stockholders since executives only realize value when the stock price increases. Our core long-term incentive is comprised solely of performance-contingent stock options. We grant service-based stock options periodically to executives upon hire or promotion, to recognize exceptional performance or for retention. All of our stock option awards are subject to a minimum one-year vesting period from the date of grant for partial vesting.
We grant performance-contingent stock options to our NEOs on an annual basis as determined by our Compensation Committee. Our Compensation Committee also reviews the equity plan “burn” rate and related information, including reference data for peer companies and overall industry practices annually.
34

VehicleStructureRationale
Performance-contingent stock options ("PSOs")
Target number of options are granted at the beginning of each year;
Options are earned based on non-GAAP operating income and bookings goals, each weighted 50%;
No options are earned for the performance metric if threshold level of performance is not achieved;
Opportunity to earn above target on each performance measure although the total number of options earned is capped at target (i.e., no upside); and
 Any earned options vest 25% immediately (i.e., one year after date of grant) and the remaining vests in equal quarterly installments over the subsequent 36 months.
 Highly performance-oriented program that focuses on driving financial performance that leads to increased long-term shareholder value.
 Entire core annual long-term incentive is at risk which creates very strong alignment with stockholders.
 On the date of grant, these awards have zero intrinsic value and executives only realize value if they achieve financial goals and the stock price increases.
Service-based stock options
Granted in limited circumstances (i.e., at hire or promotion, to recognize truly exceptional performance or retention of an executive).
In general, vests 25% on the first anniversary date and the remaining vests in equal quarterly installments over the subsequent 36 months.
Recognizing the PSOs are fully at risk, the service-based stock options are intended to provide alignment with stockholders at time of grant.
This type of award is also critical in helping to recruit top talent as we are often competing with companies that are delivering long-term incentives with less risk (e.g., service-based full value shares which we do not provide).

We provide grants of stock options to our NEOs under our 2019 Plan on an annual basis as determined by our Compensation Committee. Our stock option grants have either performance-contingent and/or service-based vesting as described above, with all awards subject to a minimum one-year vesting period from the date of grant. Our Compensation Committee also reviews the equity plan “burn” rate and related information, including reference data for peer companies and overall industry practices annually.

Our Compensation Committee approves equity grants at regularly scheduled Committee meetings. Our annual PSO grant is made in February.
Initial awards at the time of hire or promotion and retention awards generally vest solely based on the continued service of the NEO. The size and terms of the initial equity grant made to each new NEO is primarily based on competitive conditions applicable to the NEO’s specific position and, in the case of a new hire executive leaving his or her prior company, the value of unvested equity. In addition, we consider the number of shares of our common stock underlying stock options granted to other executives in comparable positions within the Company.
2023 Stock Option Awards

On February 9, 2023, the Compensation Committee approved an annual grant of performance-contingent stock options for our NEOs based on specific financial targets for 2023 (the “2023 Performance-Contingent Stock Option”) to our NEOs. The actual number of shares earned is contingent upon achievement of annual corporate financial targets for bookings and non-GAAP operating income for fiscal year 2023 (collectively, the “2023 Performance Metrics”), each weighted 50%. As discussed above, in June 2023, management lowered the financial targets in the annual operating plan, which was approved by the Board, and the Compensation Committee approved lowering the target goals for the adjusted 2023 Performance Metrics.

The 2023 Performance-Contingent Stock Options were earned based on achievement on our 2023 Performance Metrics. If non-GAAP operating income and bookings are below 80% of target, no options would be earned, and the 2023 Performance-Contingent Stock Options would be forfeited in full. For each metric, if the threshold of 80% of target is
35

achieved, then the options are earned at 50%, with an increasing percentage of options earned above threshold up to 100% earned for target performance. Executives have an opportunity to earn above target for each metric (up to 125% of options earned) although the total number of PSOs earned is capped at 100% of target (i.e., no upside). The table below outlines the performance achievement opportunity for the 2023 Performance-Contingent Stock Options.

In February 2024, the Compensation Committee certified the achievement of the 2023 Performance Metrics for non-GAAP operating income and bookings. Non-GAAP operating income performance exceeded the adjusted target, and bookings performance was below the adjusted target. Based on these results, executives earned 54.5% of target PSOs.
As discussed above, Messrs. Weening and Sindelar received service-based stock options in addition to performance-contingent stock options. The Compensation Committee approved the following 2023 Performance-Contingent Stock Options and service-based stock options for the NEOs as shown in the table below.

Letter Agreements with our NEOs
Mr. Weening - Promotion to Chief Executive Officer
In connection with Mr. Weening’s promotion from president and chief operating officer to chief executive officer on September 30, 2022, the Compensation Committee approved an annual salary of $560,000 with a cash incentive opportunity set at 150% of base salary. The Compensation Committee also approved a one-time promotion grant of an option to purchase 300,000 shares of common stock with an exercise price of $73.12 which was the closing trading price of the Company’s common stock on October 28, 2022, the date of grant of the option. The option vests as to 25% of the shares underlying the option on the first anniversary of the grant date, and the remaining shares underlying the option vesting in equal quarterly installments over the subsequent 36 months. The promotion stock option grant only delivers value if the stock price increases above the exercise price. In evaluating the promotion stock option grant, the Compensation Committee considered Calix’s historical practice of making promotional stock option grants, competitive practice of initial equity grants in the recruitment of new CEO hires, the remaining grants under the Weening Letter Agreement (see below) and the earned portion of the performance-contingent option to purchase 100,000 shares of the Company’s common stock granted to Mr. Weening in 2022.
Prior Agreements
Weening Letter Agreement
In November 2019, the Compensation Committee approved, and we entered into the Weening Letter Agreement as an incentive for Weening to continue his employment with the Company. Among other considerations, the Compensation

Committee placed significant importance on the focus areas for the next stage of the Company’s execution against its long-term strategy and growth and improve our long-term financial performance as a cloud and software platform company.
Pursuant to the Weening Letter Agreement, Mr. Weening was provided an initial and subsequent annual option grants to purchase shares of the Company’s common stock subject to Mr. Weening’s continued employment with the Company. Under the Weening Letter Agreement, Mr. Weening was automatically granted an option to purchase 120,000 shares of the Company’s common stock in November 2023 (the final tranche under the letter agreement). The option grant vests and becomes exercisable over four years, with 25% of the shares underlying the option vesting on the first anniversary of the grant, and the remainder vesting in equal quarterly installments over the next 36 months. Under the Weening Letter Agreement, Mr. Weening will hold and may not transfer any shares issued upon exercise of the option until two years have lapsed from the vest date of such shares.
Sindelar Letter Agreement
In November 2019, the Compensation Committee approved, and we entered into the Sindelar Letter Agreement, pursuant to which Mr. Sindelar was granted an initial and subsequent annual option grants over five years to purchase shares of the Company’s common stock subject to Mr. Sindelar’s continued employment with the Company. Under this letter agreement, Mr. Sindelar was automatically granted an option to purchase 100,000 shares of the Company’s common stock in November 2023 (this is the final tranche under the letter agreement). The option has an exercise price per share equal to the closing trading price of the Company’s common stock on the date of grant, and vests and becomes exercisable over four years, with 25% of the shares underlying the option vesting on the first anniversary of the grant date of the option, and the remainder vesting in equal quarterly installments over the next 36 months. Under Mr. Sindelar’s letter agreement, Mr. Sindelar will hold and may not transfer any shares issued upon exercise of the foregoing option until two years have lapsed from the vest date of such shares.
Change in Control and Severance Benefits
We provide our NEOs with certain change in control and severance benefits under our Amended and Restated Executive Change in Control and Severance Plan (“CICSP”). Our Compensation Committee provides change in control and severance benefits to our NEOs to, among other things, provide security to our NEOs including in the event of a change in control of the Company.
Under the CICSP, in the event an eligible NEO’s employment with us is involuntarily terminated by us other than for Cause (as defined in the CICSP), death or disability and such involuntary termination during a Change in Control Period (as defined below), the NEO is eligible to receive (i) a cash severance payment in an amount equal to 12 months of base salary and pro-rated target bonus (ii) accelerated vesting of equity awards for the 12 month severance period, and (iii) health insurance benefit continuation for the 12 month severance period.
In the event an eligible NEO’s employment with us is involuntarily terminated by us other than for Cause, death or disability, or the eligible NEO voluntarily terminates the NEO's employment for Good Reason (as defined in the CICSP), during a period of time commencing 60 days prior to a change in control and ending 12 months following the change in control (the “Change in Control Period”), the NEO is eligible to receive (i) a cash severance payment in an amount equal to: 24 months of base salary (in the case of Mr. Weening) and 12 months of base salary (in the case of Messrs. Sindelar, Collins and Eleniak); 200% of the annual bonus opportunity at target (in the case of Mr. Weening) and 100% of the annual bonus opportunity at target (in the case of Messrs. Sindelar, Collins and Eleniak); and a pro-rata portion the eligible NEO’s annual bonus opportunity at target, (ii) 100% accelerated vesting of all equity awards and (iii) 24 months of health insurance benefit continuation (in the case of Mr. Weening) and 12 months of health insurance benefit continuation (in the case of Messrs. Sindelar, Collins and Eleniak), in each case subject to certain exceptions. The post-termination exercise period for vested options is 12 months in the event of a qualifying termination during a Change in Control Period.
Under the CICSP, an executive must execute, and not revoke during any applicable revocation period, a general release of claims against us in order to be eligible for any severance benefits. We do not provide for any tax gross-up payments under our CICSP or otherwise in connection with executive severance benefits.
Benefits
Our NEOs receive health and welfare benefits under the same programs and subject to the same eligibility requirements that apply to our employees generally. Our NEOs are also eligible to participate in our Amended and Restated Employee Stock Purchase Plan but are not eligible to participate in our Third Amended and Restated 2017 Nonqualified Employee Stock Purchase Plan.
37

Perquisites
Beginning in 2023, we offer our executives, including our NEOs, access to executive physicals available through our health care coverage. Our executives, including our NEOs, are reimbursed for up to $5,000 in costs associated with these physicals. All other benefit programs our NEOs participate in are available to all other employees.
Annual Stockholder Advisory Vote on Executive Compensation ("Say on Pay")
We hold an advisory, non-binding stockholder vote on executive compensation every year. At our 2023 Annual Meeting of Stockholders, our stockholders voted to approve, on an advisory basis, the compensation of our NEOs, with approval of 72.6% of the votes cast. The Compensation Committee intends to continue to take into consideration the outcome of our stockholders’ advisory “say-on-pay” votes along with market practices and the recommendations of its executive compensation advisor when making future compensation decisions for the NEOs. We also regularly engage in discussions with our largest institutional stockholders and solicit feedback on executive compensation as well as other areas. We take shareholder feedback seriously and believe our “go forward” compensation practices should address concerns raised, including:
Not renewing the letter agreements with Messrs. Weening or Sindelar that provided for guaranteed annual grants of service-based options, which were in addition to their core grant of performance-contingent stock options;
Recognizing the challenges in predicting annual performance as we transition from a hardware company to a platform provider, for 2024’s cash incentive we have incorporated an approach for allowing the Compensation Committee to exercise judgement within a defined range (+/- 20%) to mitigate the need for the Compensation Committee to adjust goals or payouts outside the plan structure; and
Continued the use of performance-contingent stock options that are tied to rigorous goals, as demonstrated by the 2023 payout of only 54.5% of target.
Clawback Policies
In May 2019, we adopted a clawback policy that applies to our executive officers and covers all compensation under our cash incentive programs as well as all equity awards granted or awarded after the date the policy was adopted. The policy applies in the event our financial statements are restated as a result of material non-compliance with financial reporting rules as defined in the policy and provides our Board with broad discretion as to the actions that may be taken based on circumstances leading to the restatement, including recovery of incentive-based compensation received by an executive officer in excess of what the executive officer would have been paid under the restatement.
In November 2023, we adopted a second clawback policy that applies to our executive officers and covers all compensation under our cash incentive programs as well as all equity awards granted or awarded after the date the policy was adopted, in compliance with the SEC’s adoption of new rules to implement Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as implemented by NYSE. The policy applies in the event our financial statements are restated as a result of material non-compliance with financial reporting rules as defined in the policy and provides our Board with broad discretion as to the actions that may be taken based on circumstances leading to the restatement, including recovery of incentive-based compensation received by an executive officer in excess of what the executive officer would have been paid under the restatement.
Policy Prohibiting Speculative Transactions and Hedging
In accordance with our insider trading policy, which is annually reviewed by our Nominating and Corporate Governance Committee, we do not permit any officer, director or employee, and their respective family members, to directly or indirectly participate in certain trading activities related to our common stock that are considered aggressive or speculative in nature, including short sales, publicly-traded options, hedging transactions and margin purchases. Employees, including our NEOs, are prohibited from pledging shares.
Tax and Accounting Considerations
Section 280G of the Internal Revenue Code
Section 280G of the Internal Revenue Code disallows a tax deduction for “excess parachute payments” and Section 4999 of the Code imposes a 20% excise tax on any person who receives excess parachute payments. Our executives, including our NEOs, are not eligible to receive any tax gross-up payments in the event any payments made or that may be made to them become subject to this excise tax. The Compensation Committee may take into account the implications of Section 280G in determining potential payments to be made to our executives in connection with a change in control.
38

Nevertheless, to the extent that certain payments upon a change in control are classified as excess parachute payments, such payments may not be deductible following a change in control under Section 280G.
Section 409A of the Internal Revenue Code
Section 409A of the Internal Revenue Code, which governs the form and timing of payment of deferred compensation, imposes a 20% tax and an interest penalty on the recipient of deferred compensation that is subject to but does not comply with Section 409A. As a general matter, it is our intention to design and administer our compensation and benefits plans and arrangements for all our employees and other service providers, including our NEOs, so that they are either exempt from, or satisfy the requirements of, Section 409A of the Code. The Compensation Committee will consider the implications of Section 409A in determining the form and timing of compensation awarded to our executives and will strive to structure any nonqualified deferred compensation plans or arrangements to be exempt from or to comply with the requirements of Section 409A.
Section 162(m) of the Internal Revenue Code
Section 162(m) disallows a tax deduction for any publicly-held corporation for individual compensation exceeding $1 million in any taxable year for our CEO, our CFO, any employee who is one of the top three highest compensated executive officers for the tax year; or for any employee who was an NEO for any preceding taxable year beginning after December 31, 2016 referred to as “covered employees.” The Compensation Committee does not take the deductibility limit imposed by Section 162(m) into consideration in setting compensation.
Accounting for Stock-Based Compensation
We follow Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC Topic 718”) for our stock-based compensation awards. ASC Topic 718 requires companies to calculate the grant date “fair value” of their stock-based awards using a variety of assumptions. ASC Topic 718 also requires companies to recognize the compensation cost of their stock-based awards in their income statements over the period that an employee is required to render service in exchange for the award. Grants of stock options and other stock-based awards under our equity incentive award plans will be accounted for under ASC Topic 718. Our Compensation Committee will regularly consider the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Potential Payments Upon Termination or Change of Control
Under our CICSP, each of our NEOs may be entitled to severance upon an involuntary termination for reasons other than Cause, death or disability or, only during a Change in Control Period, a resignation for Good Reason (all as defined in the CICSP) under our CICSP (subject to certain conditions in the CICSP, with each such termination event, a “Covered Termination”). See the section above entitled “Change in Control and Severance Benefits” for more information regarding the benefits provided under our CICSP.

CEO PAY RATIO
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to disclose the ratio of our principal executive officer’s annual total compensation to the annual total compensation of our median employee.
On December 31, 2023, when we determined the median employee, Mr. Weening was the principal executive officer of Calix. For 2023, the annual total compensation for Mr. Weening was $7,155,795, as disclosed under the Summary Compensation Table above, and the annual total compensation for our median employee was $125,913, calculated using the same methodology as applied for Mr. Weening in the Summary Compensation Table above, resulting in a pay ratio of approximately 56.8:1. Annual total compensation includes compensation awarded, earned or paid during 2023.
In accordance with Item 402(u) of Regulation S-K, we identified the employee with compensation at the median of the annual total compensation of all of our employees by examining the calendar year total cash compensation between January 1, 2023 and December 31, 2023 (using December 31, 2023 as the “median employee determination date”), including salary or wages plus overtime paid, and any earned cash incentive compensation for 2023, for all individuals, excluding Mr. Weening, who were employed by us on the median employee determination date, whether employed on a full-time, part-time, seasonal or temporary basis, subject to the application of the “de minimis” exemption as described below. For employees paid other than in U.S. dollars, we converted their compensation to U.S. dollars using FX rates in effect on the median employee determination date. For employees on a leave of absence, we calculated compensation on an annualized basis. However, we did not include employees absent on an unpaid leave of absence for the entire measurement period (i.e., all of 2023). For employees hired between January 2, 2023 and the median employee determination date, we calculated their salary or wages as if they had been employed for the entire measurement period.
The de minimis exemption allows us to exclude up to 5% of our total employees who are non-U.S. employees. Our total number of employees, including U.S. and non-U.S. employees, as of the median employee determination date was 1,741 and we used this number to calculate the maximum number of employees excludable under the de minimis exemption. Accordingly, in identifying the median employee, we used the de minimis exemption to exclude approximately 19 employees (1% of our total employees) who were employed in countries outside of the United States, Canada, China and India.
We believe the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules. Because the SEC rules allow companies to utilize different methodologies and companies have different employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above.
Pay for Performance
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the following disclosure is provided about the relationship between executive compensation and the Company’s performance on select financial metrics. The “Compensation Actually Paid” and other compensation figures shown here are calculated in accordance with applicable regulatory guidance. More information on our compensation program and decisions for the 2023 performance year can be found in the Compensation Discussion and Analysis section.

DIRECTOR COMPENSATION
Our Compensation Committee reviews compensation for our non-employee directors on an annual basis, taking into consideration market data for our peer group, recommendations from its compensation advisor based on market data analysis and governance considerations issued by proxy advisory firms. Compensation for our non-employee directors consists of cash retainers for service on the Board and Board committees, with an initial equity award granted upon joining the Board and an annual equity award granted on the date of each annual meeting of stockholders. Director compensation has generally been assessed and compared to peer companies at approximately the 50th percentile of peer company compensation and practices. We do not provide for any per meeting fees for attendance at meetings. Members of the Board who are employees of Calix do not receive any compensation for their service as directors.
Non-Employee Director Cash Compensation
The table below shows the cash compensation received by our non-employee directors. Based on the market assessment conducted by our advisors, we made the following changes to our non-employee director cash compensation in February 2023: increasing the annual Board Chair retainer by $25,000 to $75,000, and increasing the annual committee member retainers by $2,500 to $12,500 for the Audit Committee and $10,000 for the Compensation Committee, respectively. All other cash compensation was unchanged.

Non-Employee Director Equity Compensation
Equity compensation for non-employee director service is granted in the form of stock options rather than RSUs and is provided through our Non-Employee Director Equity Compensation Policy. The value of the initial equity grant to newly elected or appointed Board members and the value of annual equity grants to existing Board members is $200,000. Under the Non-Employee Director Equity Compensation Policy, each non-employee director newly elected or appointed to the Board will automatically be granted an option to purchase a number of shares of common stock of the Company equal to the product obtained by multiplying (a) the result of dividing (i) $200,000 by (ii) the Black-Scholes value of an option to purchase one share of common stock of the Company as of the date of grant, as described below, by (b) a fraction, the numerator of which is the number of whole days that will have passed from the date of election through the scheduled date of the Company’s next annual stockholder meeting and the denominator of which is 365, rounded down to the nearest whole share. The Black-Scholes value of an option to purchase a share of common stock of the Company shall be determined using the per share trading price of the Company’s common stock on the date of grant.
49

Both the initial option grants and the annual option grants shall vest and become exercisable with respect to 100% of the shares of common stock underlying the option on the earlier of (i) the one-year anniversary of the date of grant or (ii) the day immediately preceding the date of the annual meeting of stockholders that occurs in the year following the year of grant.
Members of the Board who are Calix employees and who subsequently terminate employment with Calix and remain on the Board are not eligible for initial grants of equity but are eligible, after termination of employment with Calix, for annual grants.
All option awards held by a non-employee director, regardless of when granted, automatically accelerate in the event of a change in control of Calix.
Limits on Non-Employee Director Equity Awards
Under our 2019 Plan, the grant date fair value of equity-based awards granted to a non-employee director during any calendar year shall not exceed $750,000.
Limited Pledging Policy
In limited circumstances and in accordance with pre-approved guidelines, members of the Board may pledge their Calix stock holdings (exclusive of options, restricted stock units, warrants or other rights to purchase Calix stock) as collateral for a loan, including margin loans, only if approved in advance by the Company’s General Counsel.
Director Stock Ownership Guidelines
Under our director stock ownership guidelines, each director is expected to acquire and maintain ownership of Calix common stock having a value of no less than four (4) times the annual Board cash retainer, which achievement of the requisite stock ownership expected on or before the date five years after the initial appointment date of such director. If a director fails to meet these guidelines, shares from such director’s annual equity grants will be held until the guidelines are met. Each of our directors is currently in compliance with and have shareholding in excess of our director stock ownership guidelines.
Other Arrangements
We reimburse non-employee directors for travel, lodging and other expenses incurred in connection with their Board service and attendance at Board and committee meetings.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
Calix’s Board and Audit Committee have adopted a written related person transaction policy that sets forth the policies and procedures for the review and approval or ratification of related person transactions that may be deemed “related person transactions” under the rules of the SEC. This policy covers any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which Calix was or is to be a participant, the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness or employment by Calix of a related person. For purposes of the policy, a “related person” is a director, officer or greater than 5% beneficial owner of Calix’s stock and their immediate family members.
Calix recognizes that related person transactions can present potential or actual conflicts of interest or create the appearance of a conflict of interest. Management presents to the Audit Committee each proposed related person transaction, including all relevant facts and circumstances, and the Audit Committee reviews the relevant facts and circumstances of each related person transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party and the extent of the related person’s interest in the transaction, takes into account the conflicts of interest and corporate opportunity provisions of Calix’s Code of Business Conduct and Ethics, and either approves or disapproves the related person transaction. Any related person transaction may be consummated and shall continue only if the Audit Committee has approved or ratified such transaction in accordance with the guidelines set forth in the policy. No director may participate in approval of a related person transaction for which he or she is a related person. As required under rules issued by the SEC, transactions that are determined to be directly or indirectly material to a related person are or will be disclosed in Calix’s proxy statements.
During fiscal year 2023, Calix has not participated in any transactions, nor are there any currently proposed transactions in which Calix will participate, where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material interest.
Indemnification of Directors and Officers
Calix’s amended and restated certificate of incorporation and amended and restated bylaws provide that Calix is required to indemnify its directors and officers, in each case to the fullest extent permitted by Delaware law. Calix has entered into and expects to continue to enter into agreements to indemnify its directors, executive officers and other employees as determined by the Board.
HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials, proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials, or proxy statement and annual report, as applicable, addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.
This year, a number of brokers with account holders who are Calix stockholders will be “householding” our proxy materials. A single Notice of Internet Availability of Proxy Materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you notify your broker or Calix that you no longer wish to participate in “householding.”
If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, you may (1) notify your broker, (2) direct your written request to: Investor Relations, Calix, Inc., 2777 Orchard Parkway, San Jose, California 95134 or (3) contact our Investor Relations department by email at InvestorRelations@calix.com or by telephone at (408) 474-0080. Stockholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials at their address and would like to request “householding” of their communications should contact their broker. In addition, Calix will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Notice of Internet Availability of Proxy Materials to a stockholder at a shared address to which a single copy of the documents was delivered.

OTHER MATTERS
The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the proxy card to vote on such matters in accordance with their best judgment.
ANNUAL REPORTS
The 2023 Annual Report to Stockholders, including our 2023 Annual Report on Form 10-K (which is not a part of our proxy soliciting materials), will be mailed with this Proxy Statement to those stockholders that request and receive a copy of the proxy materials in the mail. Stockholders that received the Notice of Internet Availability of Proxy Materials can access this Proxy Statement and our 2023 Annual Report at www.proxyvote.com.
We have filed our Annual Report on Form 10-K for the year ended December 31, 2023 with the SEC. It is available free of charge in the “SEC Filings” section of our website at investor-relations.calix.com or at the SEC’s website at www.sec.gov. Upon written request by a Calix stockholder, we will mail without charge a copy of our Annual Report on Form 10-K, including the financial statements and financial statement schedules, but excluding exhibits to the Annual Report on Form 10-K.

Use of Non-GAAP Financial Information
Calix uses certain non-GAAP financial measures to supplement its consolidated financial statements, which are presented in accordance with GAAP. In this proxy statement, Calix has presented non-GAAP operating income and non-GAAP gross margin. These non-GAAP measures are provided as performance targets in our executive cash incentive plan as the measure primarily excludes certain non-cash charges for stock-based compensation, intangible asset amortization, and inventory and component liability charges, which Calix believes are not indicative of its core operating results. The presentation of these non-GAAP measures is not meant to be a substitute for results presented in accordance with GAAP, but rather should be evaluated in conjunction with the comparable GAAP measure. A reconciliation of these non-GAAP measures to the most directly comparable GAAP measures are provided above. The non-GAAP financial measures used by Calix may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.
