Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis.

If you deliver a proxy card by mail or vote by telephone or online, the proxy holders will vote your shares in accordance with the instructions that you provide. If you do not specify how to vote your shares, the proxy holders will vote them (i) “FOR” each of the nominees for director named herein, (ii) “FOR” the ratification of appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2023, (iii) “FOR” approval of, as an advisory vote, the compensation for the Named Executive Officers, (iv) “ONE YEAR” for the frequency of future advisory votes on executive compensation; (v) “FOR” approval of our 2023 Equity Incentive Plan and the number of shares reserved for issuance under the 2023 Equity Incentive Plan; and (vi) in accordance with the recommendations of our Board of Directors, or, if no recommendation is given, in the discretion of the proxy holders, on any other business at the Annual Meeting.

How Are Votes Counted

We will appoint a tabulator and inspector of election at the Annual Meeting. The tabulator and inspector of election is typically a representative of our transfer agent. The tabulator and inspector of election will collect all proxies and ballots and tabulate the results.

Revoking Your Proxy

You may revoke your proxy at any time before the Annual Meeting by:

Vote Required for the Proposals

The votes required to approve the proposals to be considered at the Annual Meeting are as follows:

Proposal 1—Election of Directors. The eight nominees for the Board of Directors receiving the highest number of affirmative votes cast at the Annual Meeting, online or by proxy, will be elected as directors. You may vote “FOR” the nominees for election as directors, or you may “WITHHOLD” your vote with respect to one or more nominees. For purposes of determining whether a quorum exists for the Annual Meeting, if you return a proxy card or vote by telephone or online before the Annual Meeting and withhold your vote from the election of any of the directors, your shares will be counted as present.

If any director receives a greater number of “WITHHOLD” votes than “FOR” votes, then pursuant to our Corporate Governance Policies, such director is required to submit a letter of resignation for consideration by the Nominating and Governance Committee of the Board of Directors (the “Nominating and Governance Committee”). The Nominating and Governance Committee shall recommend to the Board the action to be taken with respect to such offer of resignation, including acceptance or rejection. Within 120 days of the Annual Meeting, the Board of Directors will act with respect to such offer of resignation.

3

Proposal 2—Ratification of the appointment of our independent registered public accounting firm. Ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2023, requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. You may vote “FOR,” “AGAINST,” or “ABSTAIN,” from the proposal to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2023.

Proposal 3—Advisory Vote to Approve Named Executive Officers’ Compensation. Approval of the non-binding, advisory vote on the compensation of the Named Executive Officers requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. The Board of Directors will consider the outcome of the vote when making future decisions regarding the compensation of the Company’s named executive officers. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to approve the compensation of the Named Executive Officers.

Proposal 4—Advisory Vote on the Frequency of Future Advisory Votes on Executive Compensation. Approval of the non-binding, advisory vote on frequency of future advisory votes on executive compensation requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. The Board of Directors will consider the outcome of the vote when making future decisions regarding the frequency of future advisory votes on executive compensation. You may vote “ONE YEAR,” “TWO YEARS,” “THREE YEARS,” or “ABSTAIN” on the proposal to determine the frequency of future advisory votes on executive compensation.

Proposal 5—Approval of our 2023 Equity Incentive Plan and the number of shares reserved for issuance under the 2023 Equity Incentive Plan. Approval of the 2023 Equity Incentive Plan requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to approve the 2023 Equity Incentive Plan and the number of shares reserved for issuance under the 2023 Equity Incentive Plan.

Quorum; Abstentions; and Broker Non-Votes

A majority of the shares of common stock issued and outstanding on the Record Date, present online at the Annual Meeting or represented at the Annual Meeting by proxy, will constitute a quorum. A quorum must be present in order to hold the Annual Meeting and to conduct business. Your shares are counted as being present if you vote online at or before the Annual Meeting, by telephone, or by submitting a properly executed proxy card.

Abstentions are counted as shares present at the Annual Meeting for purposes of determining whether a quorum exists. Abstentions have no effect on Proposal 1, the election of directors. Because abstentions will be included in tabulations of shares entitled to vote for purposes of determining whether a proposal has been approved, abstentions have the same effect as negative votes on Proposal 2, the ratification of the appointment of our independent registered public accounting firm, on Proposal 3, the approval of the Named Executive Officers’ compensation, on Proposal 4, the approval of say-on-frequency votes, and on Proposal 5, the approval of the 2023 Equity Incentive Plan and the number of shares reserved for issuance under the 2023 Equity Incentive Plan.

If your broker holds your shares in its name (also known as “street name”), your broker is not permitted to vote your shares if it does not receive voting instructions from you on any matters that are not “routine” matters. Proposal 2, the ratification of the appointment of our independent registered public accountant firm is the only routine matter being presented at the Annual Meeting. Shares that are not

4

permitted to be voted by your broker are called “broker non-votes.” Under the Delaware General Corporation Law, broker non-votes count as being present for purposes of determining whether a quorum of shares is present at a meeting but are not counted for purposes of determining the number of votes cast for or against a proposal. Broker non-votes will not affect the outcome of any matter being voted at the Annual Meeting, assuming that a quorum is obtained.

The Notice sets forth instructions on how to vote over the Internet and also how to request paper copies if that is your preference.

This process is designed to provide stockholders with easy access to our proxy materials, while reducing the printing, distribution, and environmental costs of the proxy process. However, if you would prefer to receive printed proxy materials, please follow the instructions included in the Notice.

Eliminating Duplicative Proxy Materials

Similarly, if you share an address with another stockholder and have received multiple copies of our proxy materials, you may contact us at the address or telephone number specified above to request that only a single copy of these materials be delivered to your address in the future. Stockholders sharing a single address may revoke their consent to receive a single copy of our proxy materials in the future at any time by contacting our distribution agent, Computershare, either by calling toll-free at 1-800-564-6253, or by writing to Computershare, at https://www-us.computershare.com/Investor/#Contact/Enquiry.

Environmental, Social and Governance Highlights

Board Oversight of Environmental, Social, and Governance Efforts

The Board believes that focusing on sustainable business practices that reduce business risk and advance the long-term goals and objectives of our stakeholders will derive positive results. The Board has assigned primary oversight of the Company’s Environmental, Social, and Corporate Governance (“ESG”) efforts to the Nominating and Governance Committee. The Nominating and Governance Committee coordinates ESG oversight activities with the Audit Committee and Compensation Committee of the Board of Directors (the “Audit Committee” and “Compensation Committee,” respectively). The Audit Committee is responsible for reviewing with management and the independent auditors any required ESG disclosures included within the Company’s SEC filings, including human capital disclosures and the adequacy of applicable internal controls related to such disclosures. Additionally, the Compensation Committee reviews with management certain ESG matters relating to the Company’s workforce and the tying of executive compensation to the successful completion of ESG initiatives. The Company’s ESG Steering Committee, which is comprised of the Chief Financial Officer, Senior Vice President of Global Human Resources, Senior Vice President of Global Operations and Quality, and the General Counsel, leads the Company’s efforts on ESG initiatives. On a quarterly basis, senior management reports on key ESG activities to the Nominating and Governance Committee. The Nominating and Governance Committee coordinates with senior management on the periodic presentation of ESG practices and initiatives to the Board.

ESG Governance Structure

ESG Initiatives

We work to conduct our business in ways that are principled, transparent, and accountable to stockholders and other stakeholders. We focus our efforts where we can have the most positive impact on our business and society and are committed to managing the risks and opportunities that arise from ESG issues.

7

Environmental

We believe that a commitment to protecting the environment and reducing consumption of natural resources benefits us and our stakeholders. As the low power, programmable leader, sustainability is a core guiding principle for our product innovation. In furtherance of our environmental initiatives, we focus on product sustainability, operational excellence, and supply chain management. With innovative process technology and design, we seek to enhance sustainability through the products we provide to our customers. We aim to improve our own sustainability efforts as we pursue these goals.

Social

We seek to grow and win together. In furtherance of our social initiatives, we focus on our people, our community, and our culture. We believe that good connections with our customers and our people lead to positive results for us. We work to do business consistent with our core values and seek to provide a workplace where each employee feels empowered to do so as well. We believe aspiring to better connections both in and out of the workplace has empowered us to better retain our employees and serve our communities.

8

Governance

We believe that we should govern ourselves in a way that encourages employees at every level to do it right, the first time. We pursue this commitment through focusing on our governance principles, ethical standards, continuous improvement, and by striving to be connected to industry practices and our stockholders. Through both formal governance practices and informal commitments to ethical culture, we believe we can operate a company that better serves its stakeholders.

For more information about our ESG efforts, please refer to our ESG Report located at https://www.latticesemi.com/About/ESG. These materials and our website are not incorporated by reference in, and are not part of, this proxy statement.

Furthermore, the Board of Directors has determined that each of the members of each of the committees of the Board of Directors is “independent” under the applicable rules and regulations of the SEC and Nasdaq.

Board Meetings and Committees

In fiscal 2022, the Board of Directors held a total of nine meetings. The independent directors meet regularly without the presence of management. Mr. Richardson, in his capacity as Chair of the Board of Directors, leads the meetings of independent directors. Each of our current directors attended over 75% of the total number of meetings of the Board of Directors and over 75% of the total number of meetings of the committees of the Board of Directors on which such director served that were held during their tenure.

Our Board of Directors currently has three primary standing committees: the Audit Committee, the Compensation Committee and the Nominating and Governance Committee. Each of these committees operates under a written charter adopted by the Board of Directors. Copies of each of the committee charters are available on our website, https://www.latticesemi.com, at “About Us—Investor Relations—Corporate Governance.”

Audit Committee

The Audit Committee oversees the accounting and financial reporting process and the external audit process of the Company and assists the Board of Directors in the oversight and monitoring of (i) the integrity of the financial statements of the Company, (ii) the internal accounting and financial controls of the Company, (iii) compliance with legal and regulatory requirements, and (iv) the qualifications, performance and independence of the Company’s independent registered public accounting firm. In this capacity, the Audit Committee is responsible for appointing the independent registered public accounting firm. In addition, the Audit Committee reviews and approves all work performed by the independent registered public accounting firm including the compensation for such services. The Audit Committee annually evaluates the qualifications, independence, and performance of the Company’s independent registered public accounting firm.

The Audit Committee meets regularly with management and with our independent registered public accounting firm, which has access to the Audit Committee without the presence of management representatives. The Audit Committee reviews and discusses with management and the independent auditors the Company’s disclosures included in the Company’s SEC filings related to environmental, social and governance matters. In addition, the Audit Committee oversees management’s enterprise risk management process and the Company’s cyber risk management program.

14

During fiscal 2022, the Audit Committee was composed of Mr. Jensen (chair), Ms. Abrams, Mr. Bettinger (beginning in December 2022), and Mr. Lederer. The Audit Committee met eight times in fiscal 2022. Our Board of Directors has determined that each of the Audit Committee members meets the financial literacy requirements under applicable Nasdaq rules and that each of the Audit Committee members qualifies as an Audit Committee Financial Expert under applicable SEC rules and as “independent” under the applicable rules and regulations of the SEC and Nasdaq.

Compensation Committee

The Compensation Committee evaluates and, subject to obtaining the agreement of all the independent directors, approves our CEO’s compensation, approves the compensation of our other executive officers and reviews succession planning for the CEO position. The Compensation Committee also administers our equity plans and handles other compensation matters. During fiscal 2022, the Compensation Committee was composed of Mr. Lederer (chair), Ms. Joshi, Krishna Rangasayee (member until April 29, 2022), Mr. Richardson (beginning May 2022), and Ms. Skillern (beginning September 2022). The Compensation Committee met six times in fiscal 2022. Our Board of Directors has determined that each of the Compensation Committee members qualifies as “independent” under the applicable rules and regulations of the SEC and Nasdaq.

The Compensation Committee annually evaluates and, subject to obtaining the agreement of all the independent directors, approves the CEO’s and other executive officers’ compensation, including (i) the annual base salary, (ii) the annual cash-based variable compensation program, including the specific goals and target award amounts, (iii) equity compensation, (iv) any employment agreement, severance arrangement, or change in control agreement/provision, and (v) any other benefits, compensation, or arrangements. The Compensation Committee reviews, approves, and recommends to the Board, corporate goals and objectives relevant to the compensation of the CEO, evaluates his or her performance in light thereof, and considers other factors related to the performance of the Company, including accomplishment of the Company’s long-term business and financial goals. The Compensation Committee consults with the CEO regarding executive officer compensation, including the specific goals established for the other executive officers in connection with the annual cash-based variable compensation program.

The Compensation Committee also reviews compensation and benefits plans affecting non-executive employees. We have determined our compensation policies and practices for our employees appropriately manage compensation-related risk and are not reasonably likely to present a material risk to the Company. The entire Board of Directors considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their areas of responsibility. For further information on risk management see “Corporate Governance and Other Matters—Board Risk Oversight.”

The Compensation Committee has the authority to retain its own compensation consultants and outside legal, accounting and other advisers at the Company’s expense. Such consultants and advisers report directly to the Compensation Committee and the Compensation Committee has the authority to approve the fees payable to such advisers by the Company and other terms of retention. The Compensation Committee does not delegate its authority to such consultants or advisers. Since July 2020, the Compensation Committee has engaged the services of Semler Brossy Consulting Group, LLP (“Semler Brossy”), a compensation consulting firm, and has considered such firm’s input in evaluating compensation trends and best practices, identifying peer group companies and benchmarking compensation data and other aspects of administering the Company’s executive compensation program and equity compensation programs. Semler Brossy serves at the discretion of the Compensation Committee. There were no conflicts of interest between the Company and Semler Brossy or the Company’s legal counsel, Wilson Sonsini Goodrich & Rosati, P.C.

Nominating and Governance Committee

The Nominating and Governance Committee identifies qualified persons to be nominated as director candidates, recommends candidates for all vacant directorships to be filled by the Board of Directors or by the stockholders, reviews and evaluates the performance of the Board of Directors and each committee of the Board of Directors, makes recommendations to the Board of Directors for nominees to the committees of the Board of Directors, and oversees compliance with our corporate governance policies. Each quarter the Nominating and Governance Committee reviews with management the development and disclosure of the Company’s ESG practices and initiatives. The Nominating and Governance Committee coordinates the Board’s support of these activities with the Audit and Compensation Committees, and coordinates with management on the periodic presentation of these practices and initiatives to the Board. During fiscal 2022, the Nominating and Governance Committee was composed of Ms. Abrams (chair), Mr. Richardson, and Ms. Joshi. The Nominating and Governance Committee met seven times in fiscal 2022. Our Board of Directors has determined that each of the Nominating and Governance Committee members qualifies as “independent” under the applicable rules and regulations of the SEC and Nasdaq.

The Nominating and Governance Committee believes that each of the Company’s directors should have certain minimum personal qualifications, including the following:

The Nominating and Governance Committee evaluates candidates for nomination on the basis of their individual qualifications, and also on the basis of how such individuals would provide valuable perspective or fill a need on the Board of Directors. Factors in such determination include:

The Nominating and Governance Committee believes that it is necessary for each of the Company’s directors to possess many qualities and skills. The Nominating and Governance Committee typically seeks individuals with extensive experience and who bring a broad range of competencies to the role. When searching for new candidates, the Nominating and Governance Committee considers the evolving needs of both the Company and the Board and searches for candidates that fill any current or anticipated future gap. The Nominating and Governance Committee does not have a formal policy with

16

respect to diversity; however, the Board and the Nominating and Governance Committee believe that it is essential that the members of our Board of Directors represent diverse viewpoints, background and experiences and considers or seeks candidates considering the diverse communities, geographies, and demographics in which we operate. In addition, the Nominating and Governance Committee believes that diversity, including gender, ethnic, racial and LGBTQ+ diversity, is important to assure that the Board is representative of our investors, our employees and our communities. In considering candidates for the Board, the Nominating and Governance Committee considers the entirety of each candidate’s credentials in the context of these standards. With respect to the nomination of continuing directors for re-election, an individual’s contributions to the Board of Directors are also considered. For further description of the current Board of Directors’ qualifications, skills and experiences, please see “Corporate Governance and Other Matters—Director Qualifications, Skills and Experiences.”

The Nominating and Governance Committee will consider candidates for our Board of Directors who have been suggested by its members, other members of the Board of Directors, our senior management, individuals personally known to members of our Board, and our stockholders.

From time to time, the Nominating and Governance Committee may solicit proposals for candidates from interested constituencies or may use paid third-party search firms to identify candidates. The Nominating and Governance Committee evaluates candidates in the same manner regardless of how such candidates are brought to the attention of the Nominating and Governance Committee.

Compensation Committee Interlocks and Insider Participation

During fiscal 2022, no interlocking relationships existed between any member of the Board of Directors or Compensation Committee and any member of the board of directors or compensation committee of any other company.

Process for Stockholders to Recommend Candidates for Election to the Board of Directors

Stockholders who wish to submit names of candidates for our Board of Directors for consideration by the Nominating and Governance Committee should do so in writing, addressed to the Nominating and Governance Committee, c/o Secretary, Lattice Semiconductor Corporation, 5555 NE Moore Court, Hillsboro, Oregon 97124, and should include the following information:

17

Additional information may be requested by the Nominating and Governance Committee as appropriate.

In addition, our bylaws permit stockholders to nominate individuals to stand for election to our Board of Directors at an annual stockholders’ meeting. Stockholders wishing to submit nominations must notify us of their intent to do so on or before the date specified under “Stockholder Proposals—Other Stockholder Proposals and Director Nominations.” Such notice must include the information specified in our bylaws, a copy of which is available from our corporate secretary upon written request or can be found filed as an exhibit to our Annual Report, available at www.sec.gov, or on our website. In addition to the requirements in our bylaws, in order to comply with the universal proxy rules under the Exchange Act, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by the Exchange Act no later than 60 days prior to the anniversary date of the Annual Meeting.

Annual Meeting Attendance

Although we do not have a formal policy regarding attendance by members of the Board of Directors at our annual meetings of stockholders, directors are encouraged to attend. Six directors attended the 2022 Annual Meeting of Stockholders via remote communication.

Board Evaluation

The Company is committed to providing transparency regarding our Board and committee evaluation process. The chairperson of the Board, who is also a member of the Nominating and Governance Committee, leads the Board’s self-evaluation process, which may vary year to year but generally requires each director to complete a comprehensive evaluation of the performance of both the Board as a whole and, to the extent applicable, the committees on which the director serves. The results of the directors’ evaluations, supplemented with third-party data, are consolidated and presented to the Nominating and Governance Committee along with areas for enhancement of Board practices. On the basis of the feedback provided during the annual Board and committee evaluation, the Board and each committee determine changes to Board and committee processes and procedures, as appropriate.

Stockholder Communication with the Board of Directors

Stockholders may communicate with the Board of Directors by writing to us c/o Secretary, Lattice Semiconductor Corporation, 5555 NE Moore Court, Hillsboro, Oregon 97124. Stockholders who would like their submission directed to a member of the Board of Directors may so specify, and the communication will be forwarded, as appropriate.

Stockholder Engagement

The Company maintains an active dialogue with its stockholders to ensure a diversity of perspectives is thoughtfully considered on issues including strategy, compensation practices and a broad range of ESG issues. The Nominating and Governance Committee assesses potential updates to our corporate

18

governance practices and policies based on this feedback. To communicate broadly with our stockholders, we also seek to transparently share information relevant to our stockholders through our Investor Relations website, our Annual Report and this Proxy Statement.

Independent Chair and Board Leadership

The Board’s leadership structure consists of an independent chair (“Board Chair”). We separate the positions of Chief Executive Officer (“CEO”) and Board Chair in recognition of the differences between the two roles. The Board believes this structure provides independent Board leadership and engagement.

Given that our Chair is an independent director, the Board does not feel the need for a separate “lead independent director,” as our independent Chair performs that function. The Board takes its independence seriously and reinforces this standard with seven of the eight director nominees being independent.

Board Risk Oversight

The Board oversees the Company’s enterprise risk management processes for assessing and managing enterprise-wide risk. In carrying out this responsibility, the Board has delegated primary responsibility to the Audit Committee for oversight of management’s enterprise risk management process. Each quarter, the Audit Committee receives a risk update from management, comprised of a list of major risks faced by the Company and the status of actions intended to mitigate such risks. Throughout the year, and at least annually, the Board and the Audit Committee each review the steps management has taken to monitor and mitigate risks to the Company. The Audit Committee also routinely meets with various Company compliance personnel to obtain periodic assessment of compliance issues facing the Company. The Board or the Audit Committee also requests, when appropriate, that management conduct additional review of, or reporting on, select enterprise risks.

Cybersecurity Risk Oversight

In addition, the Audit Committee requires the Company’s management to provide periodic reports regarding the Company’s cyber risk management program. In order to respond to the threat of security breaches and cyberattacks, the Company has taken a proactive approach to data protection consisting of administrative, technical and physical safeguards. To build on the cyber security enhancements the Company implemented in 2020, which consisted of implementing enhanced firewalls, implementing additional cybersecurity monitoring by third-parties and providing mandatory cybersecurity training to all employees during the year, the Company implemented a zero trust cybersecurity architecture in 2021. During 2022 the Company completed further enhancements to its cybersecurity infrastructure. The Company also updated its incident response plan and conducted a cybersecurity tabletop exercise. The Audit Committee regularly briefs the entire Board on these matters, and the Board also receives periodic briefings on cyber threats in order to enhance our directors’ literacy on cyber issues.

19

ESG Oversight

As stated above, the Nominating and Governance Committee reviews with management the development and disclosure of the Company’s ESG practices and initiatives, coordinates the Board’s support of these activities with the Audit and Compensation Committees, and coordinates with management on the periodic presentation of these practices and initiatives to the Board.

Hedging Policy

The Company’s Insider Trading Policy prohibits our directors, officers, employees and certain agents (such as consultants and independent contractors) from engaging in short sales of our securities, transactions in publicly-traded options (such as puts and calls) or other derivative securities with respect to our securities, and hedging transactions. These individuals are also prohibited from trading our securities while in possession of material nonpublic information, trading the securities of our customers, suppliers, competitors, potential acquisitions, or partners while in possession of material nonpublic information, holding our securities in margin accounts, and pledging our securities as collateral for loans.

Director Qualifications, Skills and Experience

The Nominating and Governance Committee has determined that it is important for an effective Board to have directors with a balance of the qualifications, skills and experience. The table below sets forth certain qualifications, skills and experience of our non-employee director nominees.

DIRECTOR COMPENSATION

2022 Director Compensation Table

The following table sets forth information concerning compensation of our non-employee directors for the fiscal year ended December 31, 2022.

24

Narrative Discussion to 2022 Director Compensation Table

The Company compensates its non-employee directors with cash retainers and equity grants. The cash retainers are comprised of annual retainers for service on the Board of Directors and its standing committees. In 2022, non-employee directors received a cash retainer of $55,000, per year for service on the Board of Directors, the chairperson of the Board of Directors received an additional annual retainer of $50,000, and the chairpersons of the Audit Committee, Compensation Committee, Nominating and Governance Committee received additional annual retainers of $20,000, $15,000 and $10,000, respectively. Committee members received additional annual retainers of $10,000 for the Audit and Compensation Committees, and $5,000 for the Nominating and Governance Committee. For non-employee directors that joined the Company during 2022, the annual retainer and fees were prorated based on their dates of service commencement. Director compensation is subject to review by the Compensation Committee annually.

Directors received an RSU award following the annual meeting of stockholders for a number of shares of common stock determined by dividing $180,000 by the fair market value of a share of the common stock on the grant date (“Annual RSU Grant”), which vests and become payable with respect to 100% of the RSUs on the first anniversary of the grant date, provided that the director continues to serve as a director on such dates. If a non-employee director’s initial appointment to the Board is on a date other than the date of the Annual Meeting of Stockholders, on the 30^th day following the date of that non-employee director’s appointment, he or she receives a prorated Annual RSU Grant equivalent to the Annual RSU Grant multiplied by a fraction with (i) the numerator equal to 12 minus the number of months completed since the Company’s last annual meeting of stockholders on the effective date of the Non-Employee Director appointment, and (ii) the denominator equal to 12. In the event of a change in control, unvested RSUs and options held by our non-employee directors generally become vested and exercisable or payable in full effective immediately prior to the change in control. If Proposal No. 5 relating to approval of the 2023 Equity Incentive Plan is approved, no non-employee director may be paid compensation for service as a non-employee director that, in the aggregate, exceeds $500,000 per fiscal year, increased to $750,000 for the fiscal year in which a non-employee director joins the Board of Directors as a non-employee director. Any equity awards or other compensation paid or provided to an individual for his or her services as an employee or consultant (other than as a non-employee director), will not count for purposes of these limits.

25

PROPOSAL TWO

RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has approved the appointment of Ernst & Young LLP (“EY”) to act as our independent registered public accounting firm for the fiscal year ending December 30, 2023. Although ratification is not legally required, we are asking stockholders to ratify the appointment of EY as our independent registered public accounting firm for our current fiscal year in the interest of good corporate governance.

Representatives of EY have been invited and are expected to attend the Annual Meeting, will be given the opportunity to make a statement if they wish to do so, and are expected to be available to respond to appropriate questions.

In fiscal year 2020, the Company conducted a competitive process to determine the Company’s independent registered public accounting firm. As a result of the competitive process, the Audit Committee approved the appointment of EY as the Company’s independent registered public accounting firm effective May 8, 2020. EY has acted as the Company’s independent registered public accountant since its initial appointment.

Audit and Related Fees

Under its charter, the Audit Committee reviews and pre-approves all audit and permissible non-audit services performed by our independent registered public accounting firm. In 2021, KPMG LLP (“KPMG”), the Company’s previous independent registered public accounting firm, performed limited audit services on behalf of the Company. The Audit Committee reviewed and pre-approved the proposed fees to be charged by EY and KPMG for audit and permissible non-audit services and ratified any increase in fees resulting from an increase in the scope of work to be performed. In its review of non-audit services, the Audit Committee considered whether the provision of such services was compatible with maintaining the independence of EY and KPMG. The following table sets forth the fees for professional audit services rendered by EY and KPMG for the audit of the Company’s annual financial statements for fiscal years 2022 and 2021, and fees billed for other services rendered by EY and KPMG during those periods.

26

Pre-Approval of Audit and Non-Audit Services

The Audit Committee reviews and approves in advance all audit and non-audit services provided by the Company’s independent registered public accounting firm (or subsequently approves non-audit services in those circumstances where a subsequent approval is necessary and permissible). In this regard, the Audit Committee has the sole authority to approve the retention and termination of the independent registered public accounting firm, and to determine all audit and non-audit engagement fees and terms with the independent registered public accounting firm.

The Audit Committee appoints the independent registered public accounting firm annually. Before appointing EY as our independent registered public accounting firm for the fiscal year ending December 30, 2023, the Audit Committee carefully considered that firm’s qualifications and performance during fiscal 2022.

Vote Required

The proposal to ratify the appointment of EY requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. If the appointment of EY is not ratified, the Audit Committee will take the vote under advisement in evaluating whether to retain EY.

Recommendation

The Board of Directors recommends that the stockholders vote “FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2023.

27

PROPOSAL THREE

ADVISORY VOTE TO APPROVE,

ON A NON-BINDING, ADVISORY BASIS,

NAMED EXECUTIVE OFFICERS’ COMPENSATION

We are asking stockholders to approve a non-binding advisory resolution on the Named Executive Officers’ compensation as disclosed in this Proxy Statement. As described below in the “Executive Compensation—Compensation Discussion and Analysis” section of this Proxy Statement, the Compensation Committee believes that we should make our executive compensation arrangements and practices clear and transparent to stockholders. The Compensation Committee endeavors to align our executives’ interests with those of our stockholders, to attract, motivate and retain highly qualified executives, and to provide our executive team with additional compensation when they achieve superior financial results. The Compensation Committee and the Board of Directors believe that the compensation policies and procedures articulated in the “Compensation Discussion and Analysis” section of this Proxy Statement are effective in achieving our goals.

We urge stockholders to read the “Executive Compensation” section of this Proxy Statement beginning on page 30 of this Proxy Statement, including the “Compensation Discussion and Analysis” that discusses our Named Executive Officers’ compensation for fiscal 2022 in more detail, as well as the Summary Compensation Table and other related compensation tables, notes and narrative, appearing on pages 52 through 64 of this Proxy Statement, which provide detailed information on the compensation of our Named Executive Officers.

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as a matter of good corporate governance, we are asking stockholders to approve the following resolution at the Annual Meeting:

RESOLVED, that the stockholders of Lattice Semiconductor Corporation (the “Company”) approve, on a non-binding advisory basis, the compensation of the Named Executive Officers as disclosed in the proxy statement for the Company’s 2023 Annual Meeting of Stockholders.

Although this proposal, commonly referred to as a “say-on-pay” vote, is an advisory vote that will not be binding on the Board of Directors or the Compensation Committee, the Board of Directors and the Compensation Committee will consider the results of this advisory vote when making future decisions regarding our Named Executive Officer compensation programs. Stockholders have an opportunity to cast such an advisory vote annually, therefore, your next opportunity to do so will be at the 2024 Annual Meeting of Stockholders, subject to the outcome of Proposal 4.

Vote Required

Advisory Vote to Approve Named Executive Officers Compensation. Approval of the non-binding, advisory vote on the compensation of the Named Executive Officers requires the affirmative vote of the holders of a majority of the voting power of our capital stock present in person or represented by proxy at the Annual Meeting. The Board of Directors will consider the outcome of the vote when making future decisions regarding the compensation of the Named Executive Officers. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to approve the compensation of the Named Executive Officers.

28

Recommendation

The Board of Directors recommends that stockholders vote “FOR” the approval, on a non-binding, advisory basis of our Named Executive Officers’ compensation disclosed in this Proxy Statement.

This Compensation Discussion and Analysis describes the material elements of our executive compensation program during fiscal 2022. It also provides an overview of our executive compensation philosophy, core principles and objectives. Finally, it analyzes how and why the Compensation Committee arrived at the specific compensation determinations for our Named Executive Officers for fiscal 2022, including the key factors that the Compensation Committee considered in deciding or making recommendations to our Board of Directors with respect to their compensation.

Executive Summary

Fiscal 2022 Business Highlights

Fiscal 2022 Executive Compensation Highlights

Consistent with our performance and compensation objectives, the Compensation Committee (and, in the case of our CEO, the independent members of our Board of Directors upon the recommendation of

32

the Compensation Committee) took the following actions relating to the compensation of our Named Executive Officers for fiscal 2022:

Aligning Pay and Performance

Our executive compensation program is driven by our pay-for-performance philosophy. As a result, we structure a significant portion of our Named Executive Officers’ target total direct compensation with variable elements tied to our performance. In addition, we set challenging target and threshold performance goals under our variable compensation plans to ensure that compensation is earned based upon exceptional performance against pre-established financial, operational and strategic goals.

The following chart illustrates that, in the case of our CEO, 92% of his target total direct compensation for fiscal 2022 and, in the case of our other Named Executive Officers, on average 86% of their target total direct compensation for fiscal 2022 was “at risk” variable compensation in the form of a target annual cash incentive opportunity, a time-based RSU award and target PRSU awards.

Executive Compensation-Related Policies and Practices

We endeavor to align our executive compensation policies and practices with our governance standards. The Compensation Committee evaluates our executive compensation program on a regular

basis to ensure that it is consistent with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our executive compensation and related governance policies and practices that were in place in fiscal 2022:

Stockholder Advisory Vote on Named Executive Officer Compensation

At our 2022 Annual Meeting of Stockholders, we held a non-binding, advisory vote on the compensation of our Named Executive Officers (a “Say-on-Pay” vote) and approximately 97% of the votes cast approved our Named Executive Officers’ compensation for fiscal 2021. Our Board of Directors and Compensation Committee consider the result of the Say-on-Pay vote in determining the compensation of our executive officers. Based on the strong level of support for our executive

compensation program demonstrated by the result of last year’s Say-on-Pay vote, among other factors, the Board of Directors and the Compensation Committee determined to continue to focus on incentivizing the Named Executive Officers and paying for performance for fiscal 2022.

The Board of Directors and the Compensation Committee will continue to consider the result of the Say-on-Pay vote, as well as feedback received throughout the year, when making compensation decisions for our executive officers in the future because we value the opinions of our stockholders.

35

In addition, consistent with the recommendation of our Board of Directors and the preference of our stockholders as reflected in the non-binding, advisory vote on the frequency of future Say-on-Pay votes held at our 2017 Annual Meeting of Stockholders, we have held an annual Say-on-Pay vote. Stockholders again have the ability to provide a non-binding, advisory vote on the frequency of future Say-on-Pay votes during this Annual Meeting of Stockholders.

Compensation Philosophy

Our executive compensation program is heavily weighted towards variable and equity compensation to reinforce the following principles:

Consistent with these principles, we seek to directly link the cash-based variable compensation of our Named Executive Officers to our short-term or annual performance, while we align longer-term incentives, such as equity compensation, with the objective of enhancing stockholder value over the long term. We believe the use of equity compensation, including performance-based equity compensation, strongly links the interests of our Named Executive Officers to the interests of our stockholders.

In addition, we seek to align our total compensation packages with the competitive market (as represented by our compensation peer group) to ensure that we can continue to attract, motivate and retain our senior executives who we believe are critical to our success. Keeping that in mind, we seek to accomplish our executive compensation goals while maintaining appropriate levels of internal pay equity, both between our CEO and our other senior executives, and between our senior executives and our non-executive employees, and by considering our organizational structure, our stage in the company’s life cycle, affordability and the dilutive effect on our stockholders.

Compensation-Setting Process

Role of the Compensation Committee

Generally, the Compensation Committee discharges many of the responsibilities of our Board of Directors relating to the compensation of our executive officers. The Compensation Committee has the overall responsibility for overseeing our compensation and benefits policies generally, and overseeing and evaluating the compensation plans, policies and practices applicable to our executive officers.

The Compensation Committee makes recommendations to our independent members of the Board of Directors regarding the compensation of our CEO and determines the compensation for our other executive officers, including the other Named Executive Officers. The independent members of our Board of Directors make all final decisions regarding the compensation of our CEO.

36

In carrying out its responsibilities, the Compensation Committee evaluates whether our compensation policies and practices reflect our executive compensation philosophy; seeks to make decisions that further our philosophy and align with best compensation practices; and reviews the performance of our CEO and executive officers when making decisions and recommendations with respect to their compensation.

Each year, the Compensation Committee conducts an evaluation of our executive compensation program to determine if any changes are appropriate. The Compensation Committee also conducts an annual review of the compensation arrangements of our executive officers, typically during the first quarter of the fiscal year. The Compensation Committee’s authority, duties and responsibilities are further described in its charter, which is reviewed annually and revised and updated as warranted. The charter is available at https://ir.latticesemi.com/static-files/0d3c6d89-2fd6-466c-92e9-356bddcc293a.

In making its determinations, the Compensation Committee engages a compensation consultant (as described below) to provide support in its review and assessment of our executive compensation program; however, the Compensation Committee exercises its own judgment in making final decisions and recommendations with respect to the compensation of our executives.

Setting Target Total Direct Compensation

The Compensation Committee, with the assistance of its independent compensation consultant, reviews the base salary levels, annual cash incentive opportunities and long-term incentive compensation opportunities of our executive officers and all related performance criteria at the beginning of each year, or more frequently as warranted.

The Compensation Committee does not establish a specific target for formulating the total direct compensation opportunities of our executive officers. In making its recommendations about the compensation of our CEO and its decisions about the compensation of our other executive officers, the members of the Compensation Committee rely primarily on their general experience and subjective considerations of various factors, including the following:

37

These factors provide the framework for compensation decision-making and final decisions and recommendations regarding the compensation opportunity for our CEO and each executive officer. No single factor is determinative in setting compensation levels, nor is the impact of any individual factor on the determination of pay levels quantifiable.

The Compensation Committee does not weigh these factors in any predetermined manner, nor does it apply any formulas in developing its compensation decisions and recommendations. In making its decisions and recommendations, which are subjective in nature, the members of the Compensation Committee consider all of this information in light of their individual experience, knowledge of the Company, knowledge of the competitive market, business judgment and knowledge of each executive officer’s role, responsibilities, knowledge, skills, experience, qualifications and tenure.

The Compensation Committee does not engage in benchmarking against other companies’ compensation programs or practices to establish our compensation levels or make specific compensation decisions or recommendations with respect to our CEO and executive officers. Instead, in making its determinations, the Compensation Committee reviews information summarizing the compensation paid at a representative group of peer companies, to the extent that the executive positions at these companies are considered comparable to our positions and informative of the competitive environment and more broad-based compensation surveys to gain a general understanding of market compensation levels.

Role of Management

In discharging its responsibilities, the Compensation Committee works with members of our management team, including our CEO. Our management team assists the Compensation Committee by providing information on corporate and individual performance, market compensation data and management’s perspective on compensation matters. The Compensation Committee solicits and reviews our CEO’s proposals with respect to program structures, as well as our CEO’s recommendations for adjustments to annual cash compensation, long-term incentive compensation opportunities and other compensation-related matters for our other executive officers based on our CEO’s evaluation of their performance for the prior year.

The Compensation Committee reviews and discusses our CEO’s proposals and recommendations and considers them as one factor in determining and approving the compensation of our other executive officers. Our CEO also attends meetings of our Board of Directors and the Compensation Committee at which executive compensation matters are addressed, except with respect to discussions involving his own compensation.

38

For the 2022 Cash Incentive Plan, the target annual cash incentive award for each of our Named Executive Officers was subject to a discretionary increase or decrease of up to 100% based on a general assessment of his or her individual contributions during the year. At the beginning of the year, our CEO met with each of our other executive officers to review his or her performance for the prior year and to discuss expectations with respect to the performance of his or her respective business unit or function and such unit or function’s contributions to our overall results for the current year. These discussions were to form the basis for the evaluation of his or her performance at the end of the year with respect to his or her target annual cash incentive award. In the case of our CEO, these discussions were held with the independent members of our Board of Directors.

Role of Compensation Consultant

The Compensation Committee engages an external compensation consultant to assist it by providing information, analysis and other advice relating to our executive compensation program and the decisions resulting from its annual executive compensation review. The compensation consultant reports directly to the Compensation Committee and its chair, and serves at the discretion of the Compensation Committee, which reviews the engagement annually.

In fiscal 2022, the Compensation Committee engaged Semler Brossy, a national compensation consulting firm, to serve as its compensation consultant to advise on executive compensation matters, including competitive market pay practices for our executive officers, and assist with the data analysis and selection of the compensation peer group.

During 2022, Semler Brossy attended the meetings of the Compensation Committee (both with and without management present) as requested and provided various services including the following:

The terms of Semler Brossy’s engagement included reporting directly to the Compensation Committee chair. Semler Brossy also coordinated with our management for data collection and job matching for our executive officers. In fiscal 2022, Semler Brossy provided no other services to us.

39

The Compensation Committee has evaluated its relationship with Semler Brossy to ensure that it believes that Semler Brossy is independent from management. This review process included a review of the services that Semler Brossy provided, the quality of those services and the fees associated with the services provided during fiscal 2022. Based on this review, as well as consideration of the factors affecting independence set forth in Exchange Act Rule 10C-1(b)(4), Rule 5605(d)(3)(D) of the Nasdaq Marketplace Rules and such other factors as were deemed relevant under the circumstances, the Compensation Committee has determined that no conflict of interest was raised as a result of the work performed by Semler Brossy.

Competitive Positioning

The Compensation Committee believes that peer group comparisons are useful guides to measure the competitiveness of our executive compensation program and related policies and practices. For purposes of assessing our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a select group of peer companies.

This compensation peer group consists of technology companies that are similar to us in terms of revenue, market capitalization and industry focus. The competitive data drawn from this compensation peer group is only one of several factors that the Compensation Committee considers in making its decisions with respect to the compensation of our executive officers.

The compensation peer group that the Compensation Committee used to analyze the compensation of our executive officers and make its compensation decisions for fiscal 2022 was comprised of publicly traded technology companies who hire executive talent comparable to our executives.

In August 2022, the Compensation Committee determined no modifications were needed to the compensation peer group approved by the Compensation Committee in July 2021, which consisted of the following companies:

As part of its annual executive compensation review, the Compensation Committee used data gathered by Semler Brossy from the public filings of the companies in our compensation peer group, as well as data from special data cuts drawn from the Radford 2022 Global Technology Survey of companies that are similar to us in revenue, market capitalization and industry focus for purposes of providing additional perspective in the case of executive positions where the compensation peer group offered a limited number of relevant data points. This data permitted the Compensation Committee to evaluate the competitive market when formulating its recommendations for the total direct compensation package of our CEO and when determining the total direct compensation packages for our other executive officers, including base salary, target annual cash incentive awards and long-term incentive compensation.

40

The Compensation Committee reviews our compensation peer group at least annually and makes adjustments to its composition if warranted, taking into account changes in both our business and the businesses of the companies in the peer group.

Compensation Elements

The principal elements of our fiscal 2022 executive compensation program for our Named Executive Officers, including the Chief Executive Officer, are set forth in the following table, each of which is described in more detail below. The Compensation Committee considers the factors described under “Compensation-Setting Process – Setting Target Total Direct Compensation” above to determine the form and amount of each element of compensation similarly for our Named Executive Officers.

The following table sets forth information regarding each individual compensation element, including a description of each element and a summary of the element’s key objectives.

Base Salary

Base salary represents the fixed portion of the compensation of our Named Executive Officers and is an important element of compensation intended to attract and retain highly talented individuals.

41

Generally, we use base salary to provide each Named Executive Officer with a specified level of cash compensation during the year with the expectation that he or she will perform his or her responsibilities to the best of his or her ability and in our best interests.

Generally, the Compensation Committee reviews the base salaries of our executive officers each year as part of its annual review of our executive compensation program, with input from our CEO (except with respect to his own base salary) and considers making adjustments as it determines to be reasonable and necessary to reflect the scope of an individual’s experience, performance, individual contributions and responsibilities, position in the case of a promotion and market conditions.

In February 2022, the Compensation Committee reviewed the base salaries of our Named Executive Officers, taking into consideration a competitive market analysis prepared by Semler Brossy and the recommendations of our CEO (except with respect to his own base salary), as well as the other factors described in “Compensation-Setting Process – Setting Target Total Direct Compensation” above. Following this review, the Compensation Committee recommended to the independent members of our Board of Directors that the base salary of our CEO be increased to be more competitive with the base salaries of similarly situated chief executive officers at companies of comparable size and stage of maturity. In addition, the Compensation Committee determined to adjust the base salaries of each of our other Named Executive Officers to better align their base salaries with the competitive market. Subsequently, the increase to the base salary of our CEO was approved by the independent members of our Board of Directors in February 2022.

The base salaries of our Named Executive Officers for fiscal 2022 were as follows:

The actual base salaries paid to our Named Executive Officers in fiscal 2022 are set forth in the “2022 Summary Compensation Table” below.

Annual Cash Incentive Compensation

We use an annual cash incentive program in which all of our non-sales employees (including our Named Executive Officers) are eligible to participate to achieve our annual business goals. Although Mr. Nelson is our Senior Vice President, Worldwide Sales, he participated in our annual cash bonus program rather than our sales incentive plan in fiscal 2022. In December 2021, the Compensation Committee approved the 2022 Cash Incentive Plan to provide incentives for these employees to meet or exceed the principal business objectives set forth in our fiscal 2022 annual operating plan. Under the 2022 Cash Incentive Plan, annual cash incentive award payments were to be funded based on our level of achievement of pre-established corporate performance goals and then subject to adjustment for individual performance as described below.

Target Annual Cash Incentive Awards

For purposes of the 2022 Cash Incentive Plan, each Named Executive Officer’s target annual cash incentive award was to be based upon a specific percentage of his or her annual base salary.

42

Each Named Executive Officer’s target annual cash incentive award (as a percentage of his or her base salary) for fiscal 2022 was (i) 110% of base salary for the CEO and (ii) 75% of base salary for each of our other Named Executive Officers. The Compensation Committee increased the fiscal 2022 target annual cash incentive for our Named Executive Officers by 10 percentage points from the fiscal 2021 target to reflect current market practices.

Corporate Performance Objectives

Each Named Executive Officer was eligible to receive an annual cash incentive award payment under the 2022 Cash Incentive Plan based upon his or her individual performance and the attainment of one or more corporate performance components that were established by the Compensation Committee and which related to financial and operational objectives that were important to us.

In December 2021, the Compensation Committee selected three equally weighted performance components for the 2022 Cash Incentive Plan: (i) non-GAAP operating income, (ii) revenue, and (iii) management objectives. The Compensation Committee believed these components were appropriate because, in its view, they continued to be the best indicators of our successful execution of our annual operating plan and provided a strong emphasis on growth while managing expenses and strengthening our customer and employee relationships, which it believed would most directly influence the creation of sustainable long-term stockholder value.

For purposes of the 2022 Cash Incentive Plan:

The Compensation Committee established threshold, target and maximum achievement levels for each of the two financial performance components. To the extent that performance for either component was below the threshold performance level, there would be no payment with respect to that component. In addition, the potential payment for any such component was capped at the maximum performance level. Achievement levels and payment percentages for performance between the threshold and maximum performance levels were set forth in a matrix approved by the Compensation Committee. Payment for performance at points between those reflected in the matrix were to be calculated using straight-line interpolation.

The resulting performance levels for the two financial performance components were as follows:

Non-GAAP Operating Income

Revenue

43

The Compensation Committee also determined that the minimum threshold for either the non-GAAP operating income component or the revenue component must be attained for there to be any payout with respect to the management objectives component.

The management objectives component was based on the achievement of objectives related to (i) delivering fiscal 2022 gross margin above a pre-established target, including through product cost savings, (ii) successful execution of our new product platform, including the launch of the Lattice Avant^TM product platform, and the build-out of a new product pipeline, (iii) delivering certain application specific solutions to customers in the first, second, and fourth quarters of fiscal 2022, (iv) driving revenue growth above a specified level through the achievement of certain design wins goals, including from strategic customers, (v) achieving industry leading employee engagement and retention, (vi) expanding the previously established company-wide training program, and (vi) demonstrating continued progress on Company ESG initiatives. These management objectives were chosen in order to drive the expansion of gross margin to achieve our target business model, meet execution commitments on our new product platform, deliver additional solution value to our customers, drive new product adoption in order to achieve future revenue targets, help enhance employee engagement and development, and further our ESG initiatives. Under the terms of the 2022 Cash Incentive Plan, the maximum payout percentage was 200%.

Under the 2021 Cash Incentive Plan, the maximum payout percentage for the non-GAAP operating income, revenue and management business objective components was 200%. Under the 2022 Cash Incentive Plan, the maxim payout percentage for the non-GAAP operating income and revenue components was 250%, and the maximum payout percentage for the management objectives component was 100%. Accordingly, based on the weighting for each component, the maximum payout percentage for both the 2021 and 2022 Cash Incentive Plan was 200%. The modification of the 2022 maximum payout percentages for the individual components was made to better align with the ability to achieve and exceed the targets for each component.

Individual Performance

In addition to our actual results as measured against the corporate performance objectives under the 2022 Cash Incentive Plan, each Named Executive Officer’s, tentative annual cash incentive award payment was subject to a discretionary increase or decrease by up to 100% based on a general assessment of his or her individual contributions for the year. In the case of our CEO, this assessment was made by the independent members of our Board of Directors. In the case of each of our Named Executive Officers (other than our CEO), this assessment generally involved a review of his or her functional area for the year as well as consideration of his or her contributions to our overall financial and operational results. The purpose of the increase in the discretionary amount of the award payment was to further align payment under the 2022 Cash Incentive Plan to the contribution and performance of each of our Named Executive Officers.

Annual Cash Incentive Award Payments

In February 2023, the Compensation Committee determined the annual cash incentive award payments for our Named Executive Officers for fiscal 2022. First, the Compensation Committee reviewed our performance with respect to each of the corporate performance components and determined the extent to which each objective had been achieved for the year. Specifically, the Compensation Committee determined that our non-GAAP operating income for fiscal 2022 was approximately $254.9 million, our revenue for fiscal 2022 was approximately $660.7 million and, based on our achievement with respect to each of the pre-established management objectives for the year, our attainment level for the management objectives component was 86%.

44

Based on these results, the Compensation Committee then determined the percentage achievement of each performance component and the corresponding weighted payment level, as follows:

After the overall payment level for the corporate performance components under the 2022 Cash Incentive Plan had been determined to be 178.7%, our CEO met with the Compensation Committee and provided his recommendations with respect to any further adjustments to the Named Executive Officers’ annual cash incentive award payments based on their individual performance. The Compensation Committee considered these recommendations, as well as the assessment of the individual contributions of our CEO by the independent members of our Board of Directors and its resulting recommendation for an individual performance adjustment for our CEO, and decided to make an adjustment in the final payment under the 2022 Cash Incentive Plan to Mr. Nelson based on Mr. Nelson’s individual performance in 2022, which helped achieve 28% year over year revenue growth in 2022 and to Mr. Douglass based on his individual performance that helped ensure the successful launch of the Lattice Avant^TM platform in 2022. The Compensation Committee made no other adjustments based on the other Named Executive Officers’ individual performance.

The Compensation Committee recommended to the independent members of our Board of Directors the annual cash incentive award payment for our CEO set forth in the following table, which was subsequently approved by the independent members of our Board of Directors in February 2023. The annual cash incentive award payments to our Named Executive Officers were as follows:

The annual cash incentive award payments made to our Named Executive Officers for fiscal 2022 are set forth in the “2022 Summary Compensation Table” below.

Long-Term Incentive Compensation

We use long-term incentive compensation in the form of equity awards to incent and reward our Named Executive Officers to help drive long-term corporate performance based on the value of our common stock and, thereby, to align their interests with those of our stockholders. In fiscal 2022, these equity awards were granted in the form of both PRSU awards and time-based RSU awards. We believe that an appropriate mix of PRSU awards and RSU awards allow us to compete effectively in a highly competitive market and provide an appropriate long-term incentive for our Named Executive Officers.

45

Typically, we have granted equity awards to our executive officers as part of the Compensation Committee’s annual review of executive compensation. To date, the Compensation Committee has not applied a rigid formula in determining the size of these equity awards. Instead, the Compensation Committee determines the amount of each equity award after taking into consideration a competitive market analysis prepared by its compensation consultant, the recommendations of our CEO (except with respect to his own equity awards), the amount of equity compensation held by each executive officer (including the current economic value of his or her unvested equity and the ability of these unvested holdings to satisfy our retention objectives), as well as the other factors described in “Compensation-Setting Process – Setting Target Total Direct Compensation” above.

In February 2022, after taking into consideration a competitive market analysis prepared by Semler Brossy and the recommendations of our CEO (except with respect to his own equity awards), as well as the factors described in the preceding paragraph, the Compensation Committee recommended the independent members of the Board of Directors grant equity awards to our CEO, and granted equity awards to our Named Executive Officers, in the amounts set forth in the chart below. Such equity grants included (1) a PRSU award with performance criteria based on our relative total stockholder return (“TSR”) in comparison to an index, and (2) an RSU award with time-based vesting requirements. The independent members of our Board of Directors subsequently approved the grant of the equity awards to our CEO in February 2022. The equity awards granted to our Named Executive Officers in fiscal 2022 were as follows:

PRSU Awards

TSR-Based PRSU Awards

The TSR-Based PRSU awards will vest on the third anniversary of the date of grant based upon the total TSR of the Company relative to the Russell 2000 Index (the “Index”), an index that tracks the results of similarly-sized U.S. public companies and of which we are a constituent. The units granted will be tested for vesting on the third anniversary from the date of grant and will vest according to the following terms:

46

RSU Awards

The time-based RSU awards vest over a four-year period, with 25% of the units subject to the awards vesting on the first anniversary of the date of grant and the remaining units vesting at the rate of 6.25% of the total number of units subject to the awards as of the end of each three-month period thereafter, contingent upon each Named Executive Officer’s continued service with us through each applicable vesting date. Upon vesting, the RSU awards may be settled by issuing that number of shares of our common stock that equal the number of units that have vested.

Employee Benefits

Our Named Executive Officers are eligible to participate in the same employee benefit plans, and on the same terms and conditions, as all other full-time, salaried U.S. employees. These benefits include medical, dental and vision insurance, business travel insurance, an employee assistance program, health and dependent care flexible spending accounts, basic life insurance, accidental death and dismemberment insurance, short-term and long-term disability insurance and commuter benefits. We

also maintain a tax-qualified Section 401(k) retirement savings plan (the “Section 401(k) Plan”) that provides eligible employees, including our Named Executive Officers, with an opportunity to save for retirement on a tax-advantaged basis. Participants may make pre-tax contributions to the Section 401(k) Plan from their eligible earnings up to the statutorily prescribed annual limit on pre-tax contributions under the Code. An employee’s interest in his or her pre-tax deferrals is 100% vested when contributed. Currently, we match 100% of the first 3% of a participant’s contributions and 50% of the next 3% of the participant’s contributions to the Section 401(k) Plan, subject to an applicable annual statutory maximum per employee.

We design our employee benefits programs to be affordable and competitive in relation to the market as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.

Perquisites and Other Personal Benefits

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide significant perquisites or other personal benefits to our Named Executive Officers, except as generally made available to all our employees, or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make an individual more efficient and effective, and for recruitment and retention

47

purposes. During fiscal 2022, none of our Named Executive Officers received perquisites or other personal benefits that were, in the aggregate, $10,000 or more for each individual.

In the future, we may provide perquisites or other personal benefits in limited circumstances, such as those described in the preceding paragraph. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Compensation Committee.

Employment Agreements

In October 2019, the Compensation Committee, with the assistance of the Compensation Committee’s then compensation consultant, Compensia, Inc., began reviewing the employment agreements with our Named Executive Officers in order to update these agreements for market practices, to ensure the Named Executive Officers’ ability to execute effectively, to provide for the best interests of the Company and the retention of our Named Executive Officers, and to achieve consistence among all similar officers. In fiscal 2020, the Compensation Committee approved, and we entered into, an amended employment agreement for each of our Named Executive Officers.

Each of these employment agreements provides for “at will” employment (meaning that either we or the Named Executive Officer may terminate the employment relationship at any time without cause) and sets forth the then current compensation arrangements for the Named Executive Officer, including a base salary and participation in our employee benefit programs. In addition, these employment agreements provide that our Named Executive Officers will be eligible to receive certain severance payments and benefits in connection with certain involuntary terminations of employment, including in connection with a change in control of the Company. These post-employment compensation arrangements are discussed in “Post-Employment Compensation” below.

For detailed descriptions of the employment agreements we maintained with our Named Executive Officers during fiscal 2022, see “Potential Payments upon Termination or Change in Control” below.

Post-Employment Compensation

The employment agreements of our Named Executive Officers contain certain protections in the event of their involuntary termination of employment under specified circumstances, including following a change in control of the Company. These arrangements provide reasonable compensation to the Named Executive Officer if he or she leaves our employ under certain circumstances to facilitate his or her transition to new employment. Further, in some instances we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing Named Executive Officer to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits. We also believe that these arrangements help maintain their continued focus and dedication to their assigned duties to maximize stockholder value if there is a potential transaction that could involve a change in control of the Company.

In determining payment and benefit levels under the various circumstances triggering post-employment compensation provisions under the employment agreements of our Named Executive Officers, the Compensation Committee has drawn a distinction between (i) voluntary terminations of employment without good reason or terminations of employment for cause and (ii) terminations of employment without cause or voluntary terminations of employment for good reason. Payment in the latter circumstances has been deemed appropriate in light of the benefits described in the prior paragraphs, as well as the likelihood that the Named Executive Officer’s departure is due, at least in part, to circumstances not within his or her control. In contrast, we believe that payments are not appropriate in the event of a termination of employment for cause or a voluntary resignation without good reason because such events often reflect either performance challenges or an affirmative decision by the executive to end his or her relationship without fault by the Company.

48

All payments and benefits that may be provided under a Named Executive Officer’s employment agreement in connection with a change in control of the Company are payable only if there is a subsequent loss of employment by the Named Executive Officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement instead of a single-trigger arrangement (where the vesting acceleration would apply upon the change in control) to protect against the loss of retention value following a change in control of the Company and to avoid windfalls, both of which could occur if vesting of either equity or cash-based awards accelerated automatically as a result of the transaction.

In the event of a change in control of the Company, to the extent Section 280G or 4999 of the Code is applicable to a Named Executive Officer, such individual is entitled to receive either payment of the full amounts to which he or she is entitled or payment of such lesser amount that does not trigger the excise tax imposed by Section 4999, whichever results in him or her receiving the greatest after-tax amount.

We do not use excise tax payments (or “gross-ups”) relating to a change in control of the Company and have no such obligations in place with respect to any of our Named Executive Officers.

We believe that having in place reasonable and competitive post-employment compensation arrangements in the event of a change in control of the Company are essential to attracting and retaining highly qualified executives. The Compensation Committee does not consider the specific amounts payable under the post-employment compensation arrangements when determining the annual compensation for our Named Executive Officers. We do believe, however, that these arrangements are necessary to offer compensation packages that are competitive.

For a summary of the material terms and conditions of the post-employment compensation arrangements we maintained with our Named Executive Officers during fiscal 2022, as well as an estimate of the potential payments and benefits that they would have been eligible to receive if a hypothetical change in control or other trigger event had occurred on December 31, 2022, see “Potential Payments Upon Termination or Change in Control” below.

Other Compensation Policies

Stock Ownership Policy

Our Corporate Governance Policies include a requirement that our CEO must maintain ownership of shares of our common stock equal in value to three times his base salary, while our executive officers must maintain ownership of shares of our common stock equal in value to two times their base salary. For purposes of our policy, stock ownership includes all shares of our common stock owned outright by our CEO or an executive officer or held in trust for them or immediate family members but does not include any unvested or unexercised equity compensation awards. Our CEO has five years from the date of initial appointment to this position to attain this ownership level, while each of our executive officers has five years from the later of (i) the date the Section 16 Officer is appointed as a Section 16 Officer or (ii) the date of the amendment of our Corporate Governance Policies to attain their required ownership level.

In addition, in May 2020, on the recommendation of the Compensation Committee, the Board of Directors also amended our Corporate Governance Policies to increase the stock ownership requirement for the non-employee members of our Board of Directors. As amended, the non-employee members of our Board Directors must maintain ownership of our common stock equal in value to five times his or her annual cash retainer for Board service (not inclusive of chair or committee retainers). Previously, the ownership requirement for our non-employee directors was common stock with a value

49

equal to three time his or her annual cash retainer for Board service. The existing non-employee members of our Board of Directors have three years from the date of the amendment to come into compliance with the amended ownership level. As before, new non-employee directors will have five years from the date of initial election to our Board of Directors to come into compliance with the new ownership level. Compliance is tested annually at the time of our Annual Meeting of Stockholders. Any non-employee director who fails to meet the ownership requirement as of the applicable testing date is prohibited from any trading of their Company-granted shares of common stock until he or she comes into compliance. They have three years to come into compliance.

Hedging and Pledging Prohibitions

Our Insider Trading Policy prohibits our employees (including our officers), the non-employee members of our Board of Directors and certain agents from engaging in short sales of our securities, transactions in publicly-traded options (such as puts and calls) or other derivative securities with respect to our securities, entering into hedging transactions, pledging our securities as collateral for loans and holding our securities in margin accounts. In addition, our Insider Trading Policy prohibits these individuals from trading our securities while in possession of material nonpublic information and trading the securities of our customers, suppliers, competitors, potential acquisitions or partners while in possession of material nonpublic information.

Incentive Compensation Recovery Policy

Under our Corporate Governance Policies, we will seek to recover, at the direction of the Compensation Committee after it has considered the costs and benefits of doing so, and to the extent permitted by applicable law, incentive compensation awarded or paid to an executive officer for a fiscal period if the result of a performance measure upon which the award was based or paid is subsequently restated or otherwise adjusted in a manner that would reduce the size of the award or payment. Where the result of a performance measure was considered in determining the compensation awarded or paid, but the incentive compensation was not awarded or paid based on a formula, the Compensation Committee will determine in its discretion the amount, if any, by which the payment or award should be reduced.

In addition, if an executive officer engaged in intentional misconduct that contributed to the award or payment to such executive officer of a greater amount of incentive compensation than would have been paid or awarded in the absence of the misconduct, we may take other remedial and recovery action, as determined by the Compensation Committee in its discretion.

In October 2022, the SEC adopted final Rule 10D-1 instructing national securities exchanges to establish specific listing standards that may require us to update our incentive compensation recovery policy and, on February 22, 2023, Nasdaq submitted Proposed Listing Rule 5608 to the SEC. Once Nasdaq finalizes the listing standards requiring issuers to implement a policy providing for the recovery of erroneously awarded incentive-based compensation received by current or former executive officers, the Company will update its incentive compensation recovery policy to comply with such standards.

Tax and Accounting Considerations

Deduction Limitation

Section 162(m) of the Code generally limits the amount we may deduct from our federal income taxes for compensation paid to our CEO and certain other current and former executive officers that are “covered employees” within the meaning of Section 162(m) to $1 million per individual per year, subject to certain exceptions.

To maintain flexibility to compensate our executive officers in a manner designed to promote our short-term and long-term corporate goals and objectives, the Compensation Committee has not adopted a policy that all compensation must be deductible. The Compensation Committee believes it is important to maintain cash and equity incentive compensation at an appropriate level to attract and retain the individuals essential to our financial success, even if all or part of that compensation may not be deductible by reason of the Section 162(m) limit. Accordingly, we expect to pay compensation to our executive officers that may not be fully deductible when, for example, we believe such compensation is appropriate and in the best interests of our stockholders, after taking into consideration changing business conditions and/or the executive officer’s performance.

Accounting for Stock-Based Compensation

We follow FASB ASC Topic 718, Compensation—Stock Compensation, for our stock-based compensation awards. FASB ASC Topic 718 requires us to measure the compensation expense for all share-based payments made to our employees and the members of our Board of directors, including options to purchase shares of our common stock and other stock-based awards, based on the grant date “fair value” of these awards. This calculation is performed for financial accounting purposes and reported in the compensation tables below, even though recipients may never realize any value from their awards. FASB ASC Topic 718 also requires us to recognize the compensation cost of our share- based compensation awards in our income statements over the period that a recipient is required to render services in exchange for the option or other award.

COMPENSATION COMMITTEE REPORT

We have reviewed and discussed with management the Compensation Discussion and Analysis to be included in this Proxy Statement filed pursuant to Section 14(a) of the Exchange Act. Based on the reviews and discussions referred to above, we recommended to the Board of Directors that the Compensation Discussion and Analysis referred to above be included in the Company’s Annual Report for the fiscal year ended December 31, 2022 and this Proxy Statement for the Annual Meeting.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table

Amounts in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table for fiscal years 2020, 2021 and 2022 represent payments of awards under our Cash Incentive Plan for each of those years. Each Named Executive Officer’s potential award was based on a specified percentage of his or her annual base salary and the potential award increases when and if a Named Executive Officer’s annual base salary increases. Payments under our Cash Incentive Plan are made annually based on the achievement of the goals applicable to the year.

Please see the section “Compensation Discussion and Analysis” above for more information about our Cash Incentive Plan for fiscal 2022.

Other elements of executive compensation include participation in a broad-based life and disability insurance program, broad-based medical benefits, and the ability to defer compensation pursuant to a broad-based 401(k) plan that provided matching contributions in fiscal 2021. The Company does not maintain a pension plan or any other defined benefit retirement plans.

The Company provides certain supplemental life and disability insurance coverage to executive officers and certain other members of senior management. Because the Company negotiates these insurance arrangements on a bulk basis, such insurance coverage, whether issued on a group basis or individually underwritten, is obtained by the Company at rates that are likely to be better than those obtainable by individuals seeking comparable insurance coverage on their own. The premiums paid by the Company for such supplemental insurance are considered a taxable benefit to the employee.

The principal equity components of executive compensation historically have consisted of stock options and time-based RSUs. Stock options provide a means of retention and motivation for our executives and also align their interests with long-term stock price appreciation. Time-based RSUs help us retain our executives by ensuring that they receive some value from their equity awards since the RSUs will never be out of the money. Commencing in fiscal 2018, awards of PRSUs became a principal component of executive compensation. These grants are intended to align the interests of our executives with those of our stockholders and we intend to continue our increased focus on this alignment.

All stock option grants have a per share exercise price equal to the fair market value of our stock on the date of grant and a seven-year term. The Company has not granted, nor does it intend in the future to grant, equity-based compensation awards (stock options, time-based RSUs and/or PRSUs) to executives in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our stock, such as a significant positive or negative earnings announcement. Similarly, the Company has not timed, nor does it intend in the future to time, the release of material nonpublic information based on equity award grant dates.
