			Engagement As part of our stockholder outreach in 2023 and early 2024, we contacted our top 38 stockholders, representing approximately 50% of our outstanding shares of common stock. We ultimately spoke with nine stockholders representing approximately 23% of our outstanding shares of common stock. A key component of the 2023/24 outreach was to discuss changes to our executive compensation program with our top stockholders in light of the failed say on pay vote in 2022. In response to investor feedback, we made significant changes to our 2023 executive compensation program as discussed below under “Fiscal 2023 Compensation Highlights.” In addition, we discussed key topics, including Board diversity, Board structure, sustainability related efforts, supply chain management and other governance matters. We also received feedback from some investors related to their no votes cast for the reelection of Mr. Kortlang at last year’s annual meeting. Participants A Board member (when requested), together with our General Counsel and Corporate Secretary, our head of investor relations, and other members of the corporate legal team, participated in our outreach efforts in the Fall and Winter of 2023/24. All feedback received was shared and discussed with the Compensation Committee of the Board (the “Compensation Committee”), the Nominating and Corporate Governance Committee of the Board (the “Nominating and Corporate Governance Committee”) and the full Board. Additionally, our Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”) and head of investor relations engage in meaningful dialogue with our stockholders through our quarterly earnings calls and investor-related outreach events throughout the entire year.

The charts above reflect 2023 annual base salaries, 2023 quarterly performance cash bonuses (at risk), time-based RSUs and PSUs (at risk), as reported in the Summary Compensation Table below. The charts do not include “All Other Compensation,” as reported in the Summary Compensation Table, because such amounts were less than 1% for each NEO’s aggregate compensation for 2023. The charts above do not include Jeff McNeil, our former Chief Operating Officer, as he was no longer serving as an executive officer at the end of 2023.

• Holding a say-on-pay vote every year allows our stockholders to express their views on our executive compensation program in a cadence that aligns with best practices and our annual pay decisions

•Stockholders voted on a similar proposal in 2018, with the majority voting to hold a say-on-pay vote every year

Proposal 4

See page 64

Ratify Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2024

The Board recommends a vote FOR Proposal 4

•Independent firm with reasonable fees and significant financial reporting expertise

•Deloitte & Touche LLP (“Deloitte”) has been our auditors since 2010

•The Audit Committee of the Board (the “Audit Committee”) annually evaluates Deloitte and has determined that its appointment continues to be in the best interests of our stockholders

We are asking our stockholders to elect two Class III nominees to serve on the Board for a three-year term and until their successors are duly elected and qualified. The current Class III nominees up for election are Badri Kothandaraman and Joseph Malchow. The Board currently has seven members and is divided into three classes. Class III currently has two members, Class I has two members and Class II has three members. We believe a classified board provides stability and continuity, permitting directors to develop and share institutional knowledge and focus on the long term.

Directors are elected by a plurality of the votes of the holders of shares present in person or virtually or represented by proxy and entitled to vote at the Annual Meeting on the election of directors. The two nominees receiving the highest number of votes “FOR” will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominees named below. If any or all of the nominees become unavailable for election as a result of an unexpected occurrence, shares represented by executed proxies that would have been voted for each such nominee instead will be voted for such substitute nominee as the Nominating and Corporate Governance Committee may propose. Each of the nominees is a director of Enphase and has been previously elected by the stockholders. The persons nominated for election have agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

It is the policy of the Board, as set forth in our Corporate Governance Guidelines, that any nominee for director in an uncontested election who does not receive a majority of the votes cast (i.e., receives a greater number of votes “withheld” from his or her election than votes “for” in such election) shall submit his or her offer of resignation for consideration by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee shall consider all of the relevant facts and circumstances and recommend to the Board the action to be taken with respect to such offer of resignation. The Board will then act on the Nominating and Corporate Governance Committee’s recommendation. Promptly following the Board’s decision, we will disclose that decision and an explanation of such decision in a filing with the Securities and Exchange Commission (the “SEC”) and a press release.

The two nominees receiving the most “FOR” votes from the holders of shares present in person or virtually or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “FOR” will affect the outcome. Proxies may not be voted for a greater number of persons than the number of nominees named. Our Corporate Governance Guidelines require that any nominee in an uncontested election who does not receive a majority of the votes cast shall submit an offer of resignation to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee shall consider all of the relevant facts and circumstances and recommend to the Board the action to be taken with respect to such offer of resignation as further described in the preceding section.

Richard Mora


Director since February 2014 Audit Committee Compensation Committee

The Board is responsible for selecting nominees for election as directors. The Board delegates the screening process to the Nominating and Corporate Governance Committee with the expectation that other members of the Board will participate in this process, as appropriate. The Nominating and Corporate Governance Committee periodically reviews the skills and types of experience that it believes should be represented on the Board in light of our current business needs and strategy. The Nominating and Corporate Governance Committee then uses this information to consider whether all of the identified skills and experience are represented on the Board, and may recommend to the Board that the expertise of the current members should be supplemented. The Nominating and Corporate Governance Committee takes these factors into account when looking for candidates for the Board. Candidates recommended by the Nominating and Corporate Governance Committee are subject to approval by the full Board. The Nominating and Corporate Governance Committee regularly assesses the appropriate size of the Board and whether any vacancies on the Board are anticipated because of retirement or otherwise. In the event that any vacancy is anticipated, or otherwise arises, the Nominating and Corporate Governance Committee considers various potential candidates for director.

Under The Nasdaq Stock Market LLC (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. In addition, Nasdaq listing standards require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees be independent within the meaning of the Nasdaq listing standards. Under the Nasdaq listing standards, a director will only qualify as an “independent director” if, in the opinion of a company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act of 1934, as amended (the “Exchange Act”).

The Board undertook a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, the Board determined that each of Messrs. Gomo, Kortlang, Mora and Rodgers and Ms. Haenggi do not have a relationship with Enphase that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, and that each of these is “independent” as that term is defined under the applicable rules and regulations of the SEC and the Nasdaq listing standards. Accordingly, a majority of our directors are independent, as required under Nasdaq listing standards. The Board determined that Messrs. Kothandaraman and Malchow are not “independent” as defined under the applicable Nasdaq listing standards due to their services as our president and chief executive officer and as a consultant, respectively. Mr. Malchow’s consultant agreement with Enphase expired in April 2022.

The Board and the Nominating and Corporate Governance Committee value diversity of backgrounds, age, education, experience, perspectives and leadership in different fields when identifying nominees, and we assess the effectiveness of our efforts in pursuing diversity in connection with our annual evaluations. The Board believes that the representation of gender, ethnic, geographic, cultural or other diverse perspectives expands the Board’s understanding of our customers, partners, employees, investors and other stakeholders. Presently, we have one woman director and two ethnically diverse directors.

We do not impose director tenure limits or a mandatory retirement age. The Board believes that our longer-tenured directors, with their deep historical and institutional knowledge, have a unique perspective of Enphase, which provides invaluable insight as we continue to grow and evolve. Accordingly, while director tenure is taken into consideration when making nomination decisions, the Board believes that imposing strict limits on director tenure would deprive the Board of the valuable perspectives of its most experienced members. If each director nominee is elected to the Board at the Annual Meeting, our directors will have served on the Board for an average of 8.4 years. The Board believes the current average tenure of 8.4 years for its directors is consistent with the balance the Board seeks between different perspectives brought by longer serving directors and newer directors.

In October 2022, the Board appointed Mr. Gomo to serve as the independent Chair of the Board, in addition to serving as the Lead Independent Director. In his capacity as Chair of the Board, Mr. Gomo has the authority to, among other things, call and preside over Board meetings, including meetings of the independent directors, and establish the agenda for these meetings. Accordingly, the Chair of the Board has substantial ability to shape the work of the Board. The Board believes that having an independent Chair of the Board, separate from the CEO, reinforces the independence of the Board in its oversight of the business and affairs of Enphase. In addition, we believe that having an independent Chair of the Board creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of Enphase and its stockholders. As a result, we believe that an independent Chair of the Board can enhance the effectiveness of the Board as a whole.

One of the Board’s key functions is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, the Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for Enphase. The Audit Committee has the responsibility to consider and discuss our major financial and accounting risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, as well as the performance of our internal audit function. The Audit Committee responsibilities also include oversight of cybersecurity risk management, including an annual review of our IT security. The Nominating and Corporate Governance Committee oversees the risks associated with Board and corporate governance, director independence and our human capital and sustainability initiatives. The Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Each of our committees provides reports to the full Board on their oversight activities and escalates review of risk issues to the Board as appropriate. In addition, the Board meets with certain members of our executive team, including the heads of our different organizational functions, who discuss the risks and exposures involved in their respective areas of responsibility as well as any developments that could impact our risk profile or other aspects of our business. These reports from our executive team are designed to provide timely visibility to the Board and its committees about the identification and assessment of key risks, our risk mitigation strategies and ongoing developments.

During 2023, the Board and Audit Committee focused time and attention to cybersecurity and data privacy related risks, with the Audit Committee responsible for oversight of cybersecurity, data privacy and information security. To help with this, the Audit Committee established a cybersecurity subcommittee, which includes a board member with cybersecurity expertise, and holds regular meetings. During such meetings, this subcommittee has a dedicated agenda designed to assist the Audit Committee with its cybersecurity oversight and allow it to report to the full Board if necessary. The meetings involve presentations and reports from our management, security leadership and information security team, including updates on relevant cybersecurity threats faced by the company and steps we are taking to address them.

The Board has adopted Corporate Governance Guidelines that outline the role and responsibilities of the Board and its various committees. Our Corporate Governance Guidelines are available on our website at https://investor.enphase.com/corporate-governance. Our Corporate Governance Guidelines ensure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. Our Corporate Governance Guidelines are also intended to align the interests of directors and management with those of our stockholders. Our Corporate Governance Guidelines set forth the practices that the Board intends to follow with respect to board composition and selection, the role of the Board, director orientation and education, director compensation, board meetings and involvement of senior management, board committees, CEO performance evaluation, succession planning and board assessment.

We have adopted the Enphase Energy Code of Conduct (“Code of Conduct”) that applies to all officers, directors and employees. The Code of Conduct is available on our website at https://investor.enphase.com/corporate-governance. If we make any substantive amendments to the Code of Conduct or grant any waiver from a provision of the Code of Conduct to any executive officer or director, we intend to promptly disclose the nature of the amendment or waiver on our website.

We published our inaugural ESG report in January 2021 and intend to do so on an annual basis. Our ESG efforts are overseen by our General Counsel, with participation from a senior management committee, along with board-level oversight led by the Nominating and Corporate Governance Committee. The Board receives reports on sustainability and ESG matters from the Nominating and Corporate Governance Committee and senior management team at a minimum on an annual basis. The current ESG report is available in the ESG section of our website. Additional information about the role of the Nominating and Corporate Governance Committee can be found in its written charter, also available to stockholders on our website. Information contained on our website is not incorporated by reference into this proxy statement or any other report we file with the SEC.

We believe that global warming and climate change present serious risk to the economic, environmental and social systems supporting human civilization. We create clean energy technologies for the world to help slow the pace of global warming, protect the environment, and accelerate the transition to a clean, accessible and resilient energy system. However, we also acknowledge that our ability to capitalize on climate opportunities continuously over the long term requires navigating climate risk successfully. We aim to align our climate change strategy disclosures in our ESG report with the recommendations of the Taskforce for Climate-Related Financial Disclosures and International Sustainability Standards Board reporting standards, given their rate of global uptake and integration with emerging ESG disclosure regulations.

The Board has determined that each member of the Audit Committee can read and understand fundamental financial statements in accordance with applicable requirements. The Board has also determined that Messrs. Gomo and Mora each qualify as an “audit committee financial expert,” as defined in SEC rules. The Board made a qualitative assessment of their level of knowledge and experience based on a number of factors, including formal education, experience as a chief financial officer for public reporting companies or experience as a chief executive officer with financial oversight responsibilities.

The Compensation Committee is composed of two directors: Messrs. Mora and Rodgers. All members of the Compensation Committee have been and are “independent,” as required by Rules 5605(a)(2) and 5605(d)(2) of the Nasdaq listing standards. The Compensation Committee met six times in 2023. The Compensation Committee has adopted a written charter, which is reviewed annually, and is available to stockholders on our website at https://investor.enphase.com/corporate-governance.

The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with our CEO and senior vice president of human resources. The Compensation Committee meets periodically in executive session, without management. From time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. Our CEO does not participate in, and is not present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel, as well as authority to obtain, at the expense of Enphase, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s independence, reasonable fees and other retention terms.

The Nominating and Corporate Governance Committee is responsible for identifying, reviewing and evaluating candidates to serve as directors (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of the Board, and developing a set of corporate governance principles. The Nominating and Corporate Governance Committee is also responsible for overseeing our ESG strategy, initiatives and policies, including communications with employees, investors and other stakeholders.

The Nominating and Corporate Governance Committee is composed of three directors: Messrs. Kortlang and Rodgers and Ms. Haenggi. All members of the Nominating and Corporate Governance Committee are independent (as independence is defined in Rule 5605(a)(2) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee met five times in 2023, and Nominating and Corporate Governance Committee business was also discussed from time to time during meetings of the Board. The Nominating and Corporate Governance Committee has adopted a written charter, which is reviewed annually, and is available to stockholders on our website at https://investor.enphase.com/corporate-governance.

The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including: having the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of Enphase, having demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.

Candidates for director are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate given the current needs of the Board, to maintain a balance of knowledge, experience and capability. This process is designed to follow the guiding principle that the composition of the Board should reflect a diversity of thought, backgrounds, skills, experiences and expertise, and a range of tenures that are appropriate given our current and anticipated circumstances. Consistent with this philosophy, in addition to the criteria set forth above and subject to the rights of any third party to designate a director, the Nominating and Corporate Governance Committee will ensure each pool of qualified candidates for additional or vacant Board positions from which

Board nominees are chosen includes candidates who bring racial and/or gender diversity. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, as it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee is committed to identifying qualified candidates of diverse qualities and backgrounds, including candidates who are women and/or candidates from underrepresented groups. In furtherance of this commitment, the Nominating and Corporate Governance Committee will proactively include candidates who are women and/or candidates from underrepresented groups in the initial list of candidates from which it will select prospective director candidates in each future director search and will require that any search firm it may engage to assist with a director search do the same.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall service during their terms, including the number of meetings attended, level of participation, quality of performance and any relationships and transactions that might impair the directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon Nasdaq listing standards, SEC rules and regulations and the advice of counsel, if necessary.

The Nominating and Corporate Governance Committee, to date, has not adopted a formal policy with regard to the consideration of director candidates recommended by stockholders and will consider director candidates recommended by stockholders on a case-by-case basis, as appropriate. The Nominating and Corporate Governance Committee believes that it is in the best position to identify, review, evaluate and select qualified candidates for Board membership, based on the comprehensive criteria for Board membership approved by the Board. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether the candidate was recommended by a stockholder. The Board amended our Amended and Restated Bylaws (as amended, the “Bylaws”), effective April 6, 2022, in order to implement proxy access. Pursuant to the proxy access provision, a stockholder or a group of no more than twenty (20) stockholders owning three percent (3%) or more of the voting power of the our outstanding capital stock continuously for at least three (3) years may nominate, and include in our proxy statement for an annual meeting, director nominees constituting up to the greater of two (2) individuals or twenty percent (20%) of the number of directors in office, provided that the stockholders satisfy the requirements specified in the Bylaws.

To date, the Nominating and Corporate Governance Committee has not received any such nominations, nor has it rejected a director nominee from a stockholder or stockholders holding more than 5% of our voting stock. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to our Corporate Secretary at the following address: 47281 Bayside Parkway, Fremont, CA 94538, at least 120 days prior to the anniversary date of the mailing of our proxy statement for the last annual meeting of stockholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of our stock and has been a holder for at least one year. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

We have not adopted a formal process for stockholder communications with the Board. However, every reasonable effort has been made to ensure that the views of stockholders are heard by the Board or individual director, and that appropriate responses are provided to stockholders in a timely manner. The Board does not recommend that formal communication procedures be adopted at this time because it believes that informal communications are sufficient to communicate questions, comments and observations that could be useful to the Board.

In addition, any interested person, including any stockholder, may communicate directly with our non-employee directors. Persons interested in communicating directly with our non-employee directors regarding any concerns or issues may do so by addressing correspondence to a particular director, or to our non-employee directors generally, in care of Enphase Energy, Inc. 47281 Bayside Parkway, Fremont, CA 94538. If no particular director is named, letters will be forwarded, depending upon the subject matter, to the Chair of the Board, or the Chair of the Audit Committee, Chair of the Compensation Committee or Chair of the Nominating and Corporate Governance Committee.

The Compensation Committee last reviewed our non-employee director compensation policy in 2020 in order to ensure that our compensation for directors remains competitive and allows us to attract and retain highly qualified members of the Board. As part of this review, the Compensation Committee had engaged AON Consulting, Inc., an independent compensation consultant, to review non-employee director compensation and provide guidance to the Compensation Committee. Based on that review, effective November 1, 2020, the Compensation Committee determined that in order to attract and retain highly qualified directors, the compensation of the non-employee directors should be updated to be more competitive. As a result, the committee approved a new Non-Employee Director Compensation Policy, which provides the following compensation package for our non-employee directors, which was in effect for 2023.


Arrangement			Compensation ($)
Annual retainer Board member			50,000
Additional retainer Audit Committee chair			25,000
Additional retainer Audit Committee member			15,000
Additional retainer Compensation Committee chair			20,000
Additional retainer Compensation Committee member			10,000
Additional retainer Nominating and Corporate Governance Committee chair			10,000
Additional retainer Nominating and Corporate Governance Committee member			5,000
Additional retainer Lead Independent Director or Chair of the Board			20,000
Additional retainer Strategic Committee member			10,000

The Non-Employee Director Compensation Policy provides that on the date of each annual stockholders’ meeting, each non-employee director will automatically receive a RSU award with value of $250,000 (calculated using the closing price of our common stock on the Nasdaq Global Market or any successor exchange on the grant date) vesting on a quarterly basis over 12 months; the lead independent director or Chair of the Board will automatically receive an additional RSU grant with a target value of $20,000 vesting on a quarterly basis over 12 months.

1The amounts reported in this column do not reflect dollar amounts actually received by our non-employee directors. Instead, these amounts represent the aggregate grant date fair value of RSU awards granted in the fiscal year ended December 31, 2023 calculated in accordance with Financial Accounting Standards Board ASC Topic 718 (“ASC 718”), disregarding the estimate for forfeitures. For a discussion of the valuation methodology used, see Note 16, “Stock-Based Compensation” of the notes to consolidated financial statements included in Item 8 of our Annual Report on Form 10‑K for the year ended December 31, 2023, as filed with the SEC on February 9, 2024.

As part of our overall corporate governance policies, and to align the interests of our non-employee directors with the interests of our stockholders, the Board believes that our non-employee directors should have a significant financial stake in Enphase. Accordingly, the Board believes that each non-employee director should own shares of our common stock with a value equal to at least five times the current cash annual retainer for Board service (excluding additional retainers for committee or chair service). As of March 2024, this guideline is equivalent to $250,000 based on a $50,000 annual retainer. Non-employee directors should achieve this ownership guideline by the end of the calendar year that is three years after the later of (1) the October 22, 2022 effective date of the Stock Ownership Guidelines or (2) the date the individual becomes a non-employee director.

			David Ranhoff Executive Vice President and Chief Commercial Officer

			Mr. Ranhoff, 69, has served as our Vice President and Chief Commercial Officer (“CCO”) since December 2017 and as our Executive Vice President and CCO since February 2020. Mr. Ranhoff joined Enphase from GCL Solar Materials, a solar energy equipment supplier, where he was the president and CEO from April 2017 to December 2017. Prior to GCL, he was with SunEdison Inc., a renewable energy company, serving as president of the Solar Materials group from July 2013 until March 2017, and as a Senior Vice President of Sales and Marketing for both the solar materials and semiconductor divisions from July 2010 to June 2013. He joined SunEdison through its acquisition of Solaicx Inc., a crystal growth manufacturing company, where he was President and CEO from May 2009 to July 2010. Mr. Ranhoff received his bachelor of science degree in electrical engineering from Northeastern University and attended the Stanford Executive Program.

We are a global energy technology company. We deliver smart, easy-to-use solutions that manage solar generation, energy storage and communication on one single platform. Our intelligent microinverters work with virtually every solar panel made, and when paired with our smart technology, results in one of the industry’s best-performing clean energy systems. As of the end of 2023, we have cumulatively shipped more than 73 million microinverters, and over four million Enphase residential and commercial systems have been deployed in more than 150 countries.

The demand environment for our products experienced a broad-based slowdown beginning in the second quarter of 2023 in the United States and in the third quarter of 2023 in Europe that continued into the fourth quarter. This resulted in elevated inventory with distributors and installers, and as a result we sold fewer microinverters to distributors and installers during the second half of 2023 compared to the first half of 2023 as they responded to this slower demand environment. In the United States, this slowdown was primarily the result of higher interest rates and the transition from Net Energy Metering (“NEM”) 2.0 to NEM 3.0 in California, which has increased the payback period for our customers in California. In Europe, this slowdown was primarily the result of a decrease in purchases in the second half of 2023 after the initial surge of sales related to onset of the armed conflict in Ukraine in 2022, and overall channel inventory correction. In addition, there has been increased uncertainty in NEM policies and solar export penalties in a key European market, which resulted in lower sales in that region.

Despite the slowdown in the second half of the year, we delivered strong financial results in 2023, as well as strong free cash flow generation. Our GAAP profitability for 2023 was $438.9 million, as compared to $397.4 million for 2022. Our non-GAAP profitability for 2023 was $613.2 million, as compared to $647.4 million for 2022. We generated $586.4 million in free cash flow in 2023, as compared to $698.4 million in 2022. We reported net revenues of $2,290.8 million for 2023, as compared to $2,330.9 million for 2022. For the year ended December 31, 2023, we sold approximately 15.5 million microinverter units, as compared to approximately 15.4 million units in 2022, and made shipments of our IQ Batteries to customers of 351.6 Megawatt-hour (“MWh”) in 2023, as compared to 508.5 MWh shipped in 2022.1

The graph below shows a comparison of the growth of our common stock as compared to the S&P 500 Index for the period from September 5, 2017 (the first trading day after Mr. Kothandaraman was appointed CEO) to December 31, 2023. As the graph below depicts, our stock has outperformed the S&P 500 over this period. Since Mr. Kothandaraman has led Enphase, our stock price has increased more than 12,023%, as compared to a 94% increase for the S&P 500 Index over the same period. The majority of Mr. Kothandaraman’s compensation has been delivered through performance-based equity awards. The equity awards he has received over time align with our growth and success and the exceptional value delivered to our stockholders since he was promoted to CEO. The information shown is historical, and share price over the indicated period should not be considered indicative of future stockholder returns or future performance.

1 See Appendix A for the most comparable reconciliation of U.S. GAAP to non-GAAP financial measures. We use these non-GAAP financial measures to analyze our operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting our business.

At the 2023 Annual Meeting, we received support of approximately 87.7% of the votes cast on our say-on-pay advisory proposal. As a result, our 2023 say-on-pay advisory proposal passed. This followed a failed say-on-pay advisory vote at our 2022 Annual Meeting of Stockholders (the “2022 Annual Meeting”) and the Compensation Committee believes that this substantial majority of votes cast affirms our stockholder’s support for the changes we made to our executive compensation program in 2023.

Based on the feedback from investors and recommendations from Compensia, our compensation consultant, following the 2022 Annual Meeting, the Compensation Committee made changes to our equity compensation program for our NEOs, taking into consideration the discussions we had with our stockholders, our outstanding performance and our record financial results in 2022, and the desire to continue to motivate our executives and create meaningful retention incentives. We summarize below the overall 2023 compensation program for our CEO as compared to our 2022 compensation program:


Summary of CEO Compensation
2022 Features						2023 Features

Base Salary: $450,000; Mr. Kothandaraman’s base salary has remained the same since his appointment to CEO in September 2017						Base Salary: $450,000; No change from 2022


Quarterly Cash Bonus Program: 100% of base salary						Quarterly Cash Bonus Program: 100% of base salary; No change from prior year, however, we added an ESG-based metric target as part of the rigorous metrics


Equity-Based Incentives Award Mix: 60%/40% Mix 60% performance-based vesting •30% tied to Annual CEO Smart Goals •30% tied to Annual Individual Performance Goals 40% time-based vesting over two years						Equity-Based Incentives Award Mix: 67%/33% Mix 67% performance-based vesting •33% tied to Annual CEO Smart Goals •34% tied to a three-year relative TSR metric 33% time-based vesting over three years

The charts above reflect 2023 annual base salaries, 2023 quarterly performance cash bonuses (at risk), time-based RSUs and PSUs (at risk), as reported in the Summary Compensation Table. The charts do not include “All Other Compensation,” as reported in the Summary Compensation Table, because such amounts were less than 1% for each NEO’s aggregate compensation for 2023. The charts above also do not include Mr. McNeil as he was no longer serving as an executive officer at the end of 2023.

•67% of the equity awards were performance-based awards. In 2023, we awarded equity in the form of time-based RSUs and PSUs under our Performance Shares Program (“PSP”) for 2023 (the “2023 PSP”), with each NEO receiving 67% of the aggregate target value of their equity awards in the form of PSUs and 33% of such value in the form of time-based RSUs. Equity awards were an integral part of our executive compensation program, and along with the rigorous goals set in our annual cash bonus program, comprised the primary “at-risk” portion of our NEOs’ compensation package.

•Cash bonuses were dependent on meeting rigorous corporate objectives. Our quarterly performance-based bonus opportunities for all of our NEOs were dependent upon achievement of quarterly corporate objectives and the performance of NEOs in meeting their own individual objectives, which were set to be aggressive and achievable, but only with significant effort. In 2023, under our bonus program (the “2023 Bonus Program”), our CEO received aggregate payouts equal to 60% of his target annual payout, and our other NEOs received aggregate payouts ranging from 53% to 64% of their target annual payouts, as further detailed below under “2023 Executive Compensation Program - 2023 Quarterly Performance Cash Bonus Program.”


Element of compensation	Objectives	Key features


Base Salary (fixed cash)	Provides financial stability and security through a fixed amount of cash to attract and retain executives.	Fixed compensation that is periodically reviewed and adjusted based on a number of factors, including individual performance, our overall company performance and market data.


Quarterly Performance Cash Bonus (at-risk cash)	Motivates and rewards through quarterly payments for attaining key corporate and individual performance goals linked to our key business objectives.	Target bonus amounts, calculated as a percentage of base salary, are periodically reviewed and determined based upon competitive bonus opportunities in our market. We award the annual bonus on a quarterly basis to incentivize and reward quarterly results that help achieve our long-term strategic goals. Bonus awards are dependent upon three components: (i) company performance objectives, (ii) company funding factor, and (iii) individual performance objectives. The Compensation Committee determines the bonus amount achieved each quarter as further described below.


Long-Term Incentives (67% PSUs (at-risk equity) and 33% RSUs)	Motivates and rewards for our longer-term performance; aligns executives’ interests with stockholder interests in creating long-term value; and attracts and retains highly qualified executives.	Variable equity-based compensation, including: (i) PSU awards that vest based on achievement of specified corporate goals measured over a one-year period (33%), (ii) PSU awards tied to a three-year relative TSR metric (as described below) (34%), and (iii) time-based RSU awards that vest over three years based on continuous service (33%).

In evaluating our executive compensation policies and programs, as well as the short-term and long-term value of our executive compensation plans, we consider both the performance and skills of each of our NEOs, as well as the compensation paid to executives in similar companies with similar responsibilities. We focus on providing a competitive compensation package, which provides significant short- and long-term incentives for the achievement of measurable corporate objectives. We believe that this approach provides an appropriate blend of short- and long-term incentives to maximize stockholder value.

We do not have any formal policies for allocating compensation among salary, bonus awards and equity grants. Instead, the Compensation Committee and Board set the compensation of our NEOs at levels they determine to be competitive and appropriate for each NEO, using the professional experience and judgment of Compensation Committee and Board members. However, in order to align the NEOs’ incentives with the interests of our stockholders and corporate goals, a significant portion of the NEOs’ total target compensation is comprised of performance-based quarterly bonus opportunities and long-term equity awards that vest based upon achievement of performance goals and also upon continuous service over time. In addition, our NEOs generally are awarded an initial new hire equity grant upon commencement of employment. We may also make equity grants to our NEOs in connection with promotions on a case-by-case basis. New hire and promotion equity grants are based primarily on competitive conditions applicable to each specific executive position.

The Compensation Committee is appointed by the Board to assist with the Board’s oversight of our compensation policies, plans and programs, administration of our equity plans and its responsibilities related to the compensation of our NEOs, directors and senior management, as appropriate. The Compensation Committee meets periodically throughout the year to manage and evaluate our executive compensation program and generally determines the principal components of compensation (base salary, quarterly performance bonuses and equity awards) for our NEOs on an annual basis; however, the Compensation Committee also approves performance cash bonus payments on a quarterly basis. The Compensation Committee may form and delegate authority to subcommittees as appropriate. However, the Compensation Committee does not delegate authority to approve NEO compensation. The Compensation Committee does not maintain a formal policy regarding the timing of granting equity awards to our NEOs, but typically does so during the beginning of the year.

The Compensation Committee works with and receives information and analysis from management, including our legal, finance and human resources departments, and our CEO, and considers the information and analyses in determining the structure and amount of compensation to be paid to our employees, including our NEOs. Our legal, finance and human resources departments work with our CEO to: design and develop recommended compensation programs for our NEOs and other senior executives; recommend changes to existing compensation programs; recommend financial and other performance targets to be achieved under those programs; prepare analyses of financial data; prepare peer data comparisons and other briefing materials; and ultimately implement the decisions of the Compensation Committee. Our CEO evaluates the individual performance of the other NEOs and provides the Compensation Committee with such NEO performance assessments and management’s recommendations and proposals regarding NEO compensation programs and decisions affecting base salaries, performance bonuses, equity compensation and other compensation-related matters outside of the presence of any other NEOs. However, the Compensation Committee and the Board retain the final authority to make all compensation decisions. While the CEO and members of our management team discuss recommendations and compensation arrangements with the Compensation Committee, they do not participate in the deliberations concerning or determination of their own compensation.

The Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. In July 2022, the Compensation Committee retained Compensia as its compensation consultant. Compensia was engaged to support a review of our approach to executive compensation with a focus on finalizing a methodology that would be responsive to investor input, be aligned with our internal culture and compensation objectives and be competitive with practices among comparable companies. The Compensation Committee assessed the independence of Compensia pursuant to SEC rules and concluded that no conflict of interest existed that would have prevented Compensia from serving as an independent consultant to the Compensation Committee.

The Compensation Committee regularly reviews our peer group to determine if adjustments are necessary to ensure that the data derived from the group continues to represent current market practices. From time to time, the Compensation Committee will revise the peer group when it determines that additional or different peer companies or groups are necessary to provide appropriate information on market practices and compensation levels. For 2023, the Compensation Committee determined that no changes were necessary to the peer group, which consisted of the following companies:


ADT, Inc.	Marvell Semiconductor, Inc.	Resideo Technologies, Inc.
Alarm.com Holdings, Inc.	Microchip Technology Incorporated	Skyworks Solutions, Inc.
ChargePoint Holdings, Inc.	Monolithic Power Systems, Inc.	SolarEdge Technologies, Inc.
First Solar, Inc.	NextEra Energy Partners, LP	Sunrun, Inc.
Generac Holdings, Inc.	ON Semiconductor Corporation	Synaptics Incorporated
Keysight Technologies, Inc.	Plug Power, Inc.	Teradyne, Inc.
Lennar Corporation	Qorvo, Inc.	Wolfspeed, Inc. (formerly Cree, Inc.)

The Compensation Committee did not “benchmark” against a specific percentile of the compensation data derived from our 2023 peer group in setting the compensation of any of our NEOs. Rather, in making executive compensation decisions, the Compensation Committee reviewed compensation data from the 2023 peer group companies (referred to as the market data) as reference points (generally at the 25th, 50th and 75th percentiles of the market data). The Compensation Committee’s general aim was for total executive compensation to remain competitive with the market, with individual amounts varying as appropriate based on corporate and individual executive performance, and other factors that were deemed appropriate for consideration. Given that we continue to evolve and grow, the Compensation Committee has not developed a specific market positioning that it consistently aims for in setting compensation levels. Instead, the Compensation Committee determines each element of compensation, and total target cash and equity compensation, for each NEO based on various facts and circumstances appropriate for our company in any given year. Competitive market positioning is only one of several factors, as described above under “Factors Used in Determining Executive Compensation,” that the Compensation Committee considers in making compensation decisions, so individual NEO compensation may therefore fall at varying levels as compared to the market data.

The Compensation Committee generally reviews our NEOs’ base salaries on an annual basis. The annual base salaries for our NEOs for 2023 are set forth in the chart below. The annual base salaries of our NEOs remained unchanged in 2023 (except for Ms. Yang who received an increase), as compared with 2022 levels, because the Compensation Committee determined that each NEO’s total compensation – comprised of salary, bonus and equity awards – remained competitive based on market data. The Compensation Committee increased Ms. Yang’s salary to better align with the market and in recognition of her performance and the criticality of her role. In addition, the Compensation Committee sought to tie a greater percentage of each NEO’s total compensation to rewarding performance, whether through bonus payments or performance-based equity awards based on the achievement of SMART Goals, as further described below.

In 2023, we added a specific goal related to ESG matters as the Board and the Compensation Committee believe this target can help Enphase achieve its long-term goals and help in value creation. The Annual CEO SMART Goals served as one of the components in determining the payout under the equity incentive compensation program, and the Quarterly CEO SMART Goals served as one of the factors in determining the payout under the quarterly cash bonus program, as further described below.

Each of our NEOs was eligible for quarterly performance bonuses under the 2023 Bonus Program. The 2023 Bonus Program was designed to align compensation with annual goals that were measured and paid quarterly, based upon Company and individual performance to better incentivize executives to achieve real-time goals, set on a quarterly basis. The Quarterly CEO SMART Goals were designed to drive revenue and gross margin growth and profitability, encourage accountability, drive execution of short-term priorities tied to long-term strategy and annual operating plan objectives, and to recognize and reward our NEOs based upon their achievement of certain individual objectives during a quarter.

The Compensation Committee approved target bonus percentages for each NEO under the 2023 Bonus Program, which were unchanged from the 2022 calendar year (the “Bonus Percentage”). Such Bonus Percentages were consistent with our philosophy that a significant portion of each executive’s total target compensation should be tied to performance, and they reflected the Compensation Committee’s review of internal pay equity. The respective target bonus percentages for our NEOs were set as follows:


	Performance Factor Range	Overview


Company Performance Factor	0 - 1.0	The level of achievement of Quarterly CEO SMART Goals


Funding Factor	0 - 1.5	The amount of actual Company quarterly profit measured against the applicable quarterly profit target that was established in January 2023. Quarterly targets that were set in January were not changed during the year


Individual Performance Factor	0 -1.2	Individual performance measured against quarterly targets set at the beginning of each quarter and approved by the CEO in the case of the NEOs other than the CEO (the “Quarterly Individual Goals”) For the CEO, the individual performance factor reflects the level of achievement of the Quarterly CEO SMART Goals

The Funding Factor for each quarter could range from 0 to 1.5, depending upon our quarterly profit before taxes before bonus (“PBB”), which was defined as our quarterly profit before taxes measured on a non-GAAP basis excluding projected bonus. The quarterly PBB targets that would determine the 2023 Funding Factor for each quarter were forward looking and approved by the Board in January 2023. The quarterly PBB targets did not change during the year. The actual Funding Factor for a quarter was determined using linear interpolation between 0 and 1.5 based on the ratio of actual PBB to the targeted PBB, with the Funding Factor for quarterly bonuses being 1.0 if actual quarterly PBB equaled targeted PBB. Actual PBB that was more than targeted PBB was capped at 1.5. No quarterly bonuses would be funded or payable if PBB fell below $500,000 for the quarter. In determining PBB, we excluded, among others, the following items: stock-based compensation expense, acquisition related expenses and amortization, and non-cash interest expense. After the end of each quarter, the Compensation Committee calculated the Funding Factor based upon the ratio of actual PBB to targeted PBB.

The Individual Performance Factor for the CEO was based on the achievement of Quarterly CEO SMART Goals; and for our other NEOs, it was based on the achievement of Quarterly Individual Goals (together with the Quarterly CEO SMART Goals, the “Quarterly Goals”). As noted above, the Quarterly CEO SMART Goals were approved by the Board in January 2023. The Quarterly Individual Goals for our NEOs (other than the CEO) were approved by the CEO at the beginning of each quarter, and were SMART goals, forward looking, and were not altered during the quarter.

The Individual Performance Factor for a quarter could be between 0 and 1.2 and was determined by taking the actual score for achievement of the Quarterly Goals, including 20 points for stretch goals, and dividing by 100. The line-item goals in the Quarterly Goals were either binary (meaning achieved or not) or based upon specific targets defined for 100% achievement and 0% achievement (“Scaled Goals”). For binary goals, all points for the goal were earned if the goal was achieved; all points were lost if the goal was not achieved. For the Scaled Goals, if the 100% target was achieved, all points assigned to that goal were earned, and if less than the 100% target was achieved, linear interpolation between the two targets would determine the actual number of points earned. After the end of each quarter, the Compensation Committee approved the Individual Performance Factor for the CEO based on the scores for the CEO Quarterly SMART Goals, and for the other NEOs, based on the scores for the Quarterly Individual Goals.

The Compensation Committee awarded equity in 2023 in the form of time-based RSUs and PSUs under the 2023 PSP to reward top talent for performance and to incentivize their retention. In 2023, the Compensation Committee provided reasonable increases in the target value of annual equity awards for all NEOs, including our CEO, to reward them for exceptional financial performance in 2022. The 2023 PSP was designed to encourage our executive staff and other selected top talent, including our NEOs, to focus on initiatives that promoted the achievement of specified, forward-looking, annual goals that were critical to lay the foundation for our success over the longer term. Also, starting in 2023, the Compensation Committee replaced the PSU award based on annual individual goals with a PSU award that could be earned based on the achievement of relative TSR performance goals over a three-year performance period.

The Compensation Committee determined an aggregate target award size for the equity incentive award for each NEO in 2023 based on our internal equity budget for all grants in 2023, internal pay equity, and for all NEOs other than the CEO, the recommendations of the CEO. The Compensation Committee also determined the CEO’s aggregate target equity award size. As noted above, the Compensation Committee provided reasonable increases in the target value of annual equity awards for all NEOs, including our CEO, to reward them for exceptional financial performance in 2022. The Compensation Committee believed that this mix of time-based RSUs and PSUs for 2023 was appropriate to promote retention, motivate executives and align pay with performance and long-term stockholder value creation.

In March 2023, the Compensation Committee initially awarded Mr. Ranhoff 4,950 RSUs under the 2023 PSP because he had previously announced his intention to retire and transition to a smaller role at the end of June 2023. However, given that Mr. Ranhoff was critical to our success and his overall importance to our long-term growth, the Board and the Compensation Committee made efforts to retain Mr. Ranhoff in his capacity as CCO. As an incentive to have Mr. Ranhoff continue in his role as CCO, and considering the number of shares awarded to other executives in 2022 and 2023, the Compensation Committee awarded Mr. Ranhoff additional awards of 13,200 time-based RSUs, which vest annually over three years, under the 2023 PSP, and 30,000 RSUs, which vest quarterly over two years, subject to his continuous service on each applicable vesting date.

There were 60 Annual CEO SMART Goals, including two stretch goals that fell within the ten broad categories described earlier, for a maximum possible score of up to 120 points, as set forth in the table below. The number of points assigned to each category was based upon our key priorities and approved by the Compensation Committee and Board in January 2023. As discussed above, except for goals that had binary targets, each goal was assigned a 100% achievement target down to a 0% achievement target, with linear interpolation between the two targets that determined the actual achievement score. The goals were all forward looking, set to be aggressive and rigorous, but attainable with significant skill and effort, as can be seen by the final achievement scores set forth in the table below. At the time that the goals were set, the Compensation Committee and the Board believed that they were substantially uncertain to be achieved. With a score of 76.09 points, our NEOs were awarded PSUs based on the level of achievement of the Annual CEO SMART Goals at 50% of target.

•Grow Revenue. The Grow Revenue category included four goals with a possible total of 27 points. 10 out of the 27 points were assigned to a goal to grow company revenue by approximately 22% to $1.950 billion in 2023. The 100% target was set at $3.0 billion and the 0% target was set at approximately $2.3 billion. An additional 10 points were assigned to a stretch goal to further grow revenue to $3.3 billion in 2023, with the 100% target set at $3.3 billion and the 0% target at 3.0 billion. We also included in the Grow Revenue category a target to grow revenue outside the United States in international geographies and to grow storage to 529 MWh. The table below shows how we performed against our goals in the Grow Revenue category.

•Profit Before Taxes ("PBT"). The PBT category included seven goals with a possible total of 19 points, which related to non-GAAP gross margin (“GM”), non-GAAP operating expenses (“OPEX”), non-GAAP PBT, non-GAAP earnings per share (“EPS”) and adjusted free cash flow. This included a five point stretch goal to improve non-GAAP GM by 200 basis points from target. In addition, the goal to maximize the benefit under the Inflation Reduction Act (“IRA”) was also considered a five point stretch goal. The table below shows how we performed against our goals in the PBT category.

•New Products. The New Products category had 16 goals for a possible total of 20 points for the introduction of certain new products or product versions, with targets based upon specific milestones. We scored 14.82 out of 20 for improving commissioning times of Ensemble and timely introduction of most new products, but not for all new product introductions. As previously mentioned, the targets that were set in January 2023 could not be and were not revised, even where the failure to meet the goal was due to reprioritization or change in our strategy.

•Operations (including IT). The Operations category had eight goals for a possible 21 points related to security, certain product cost improvements and the ramp up of U.S. manufacturing to benefit from the IRA, with targets tied to specific milestones, dollar values and percentages. We were successful in achieving certain security certifications and ramping up U.S. manufacturing, however, we scored 17.17 out of 21 on these goals due to not hitting all cost reduction targets.

•Quality and Ease of Doing Business. These two categories focused on our customer experience. The Quality category had four goals for a possible total of eight points related to maintaining or decreasing the number of defective parts per million (“DPPM”) for microinverter, battery and other products, with specific DPPM reduction targets for each quarter and for the entire year. The Ease of Doing Business (“EODB”) category had four goals for 11 points related to customer service initiatives, with targets set at improving the customer service net promoter score (“NPS”) to 73% for the year, improving wait times on solar and storage, and improving our worldwide distributor NPS to 40%, each with specific milestones or NPS targets each quarter. We achieved 6.74 out of 8 possible points on the Quality goals by meeting the microinverter and battery annual DPPM targets but did not meet the other product DPPM targets due to the aggressive nature of the targets. We scored 10.20 out of 11 possible points on the EODB goals for exceeding the NPS targets and showing improvement on wait times.

•Mergers and Acquisitions / ESG. This category had two binary goals for two points possible related to integrating an acquisition target according to certain milestones to be completed in each quarter, such as integrating employees and organizational structure, IT systems, websites, finance, contracts, intellectual property and other activities. The other goal in this category related to the installation of solar systems on certain Enphase facilities in order to reduce our carbon footprint. We achieved 1.67 out of two possible points because while all targeted solar installations were completed in 2023, one installation was not fully commissioned until the first quarter of 2024.

The Compensation Committee believes that a three-year TSR award is a substantial, at-risk component of our NEOs’ compensation tied to our long-term performance. The number of PSUs that vest, if any, depends entirely on Relative TSR for the applicable performance period. To earn the target number of PSUs, we must achieve above-median performance at the 55th percentile of the S&P 500. We measure Relative TSR for the applicable performance period based on the change in each company’s stock price during the applicable performance period, taking into account any dividends paid during that period, which are assumed to be reinvested in the stock. We use a 10-trading-day averaging period to determine the beginning and ending stock price to calculate our TSR and that of each company in the S&P 500. This averaging period mitigates the impact of one-day or short-term stock price fluctuations at the beginning or end of the performance period on the long-term Relative TSR results. For each company, the change in stock price from the beginning to the end of the performance period is divided by the beginning stock price to determine TSR.

Each of our NEOs is a participant in our Severance and Change in Control Benefit Plan (the “Severance Plan”), under which our NEOs are eligible to receive severance payments and benefits upon a termination of employment without “cause” or the resignation by a participant for “good reason” or upon such a termination in connection a change in control transaction. The adoption of the Severance Plan reflects our desire to have a consistent set of benefits across the executive team. The Compensation Committee considers these severance benefits critical to attracting and retaining high-caliber executives. Additionally, the Compensation Committee believes that additional change-in-control severance benefits minimize the distractions to an executive in connection with a corporate transaction and reduce the risk that an NEO departs our Company before a transaction is completed. We believe that the Severance Plan allows our NEOs to focus on continuing normal business operations and, in the case of change-in-control benefits, on the success of a potential business combination, rather than worry about how business decisions that may be in our best interest will impact their own financial security. The Compensation Committee periodically reviews the severance and change in control payments and benefits that we provide, including by reference to market data as appropriate, to ensure they remain appropriately structured and at reasonable levels.

To help ensure a strong alignment between the interests of our executives and stockholders, in October 2022, we adopted Stock Ownership Guidelines for our directors and executive officers. We require our non-employee directors and our NEOs to have an equity ownership interest in accordance with the following schedule by the end of the calendar year that is three years after the later of (1) the October 22, 2022 effective date of the Stock Ownership Guidelines or (2) the date the individual becomes a non-employee director subject to these guidelines:

Because we believe equity awards are an important part of our compensation program, we also grant equity awards on an annual basis to eligible employees, including our NEOs. The Compensation Committee generally approves these annual equity grants in the first quarter of each year for the NEOs and certain other key employees, and in the third quarter of each year for all other eligible employees. In addition, the Compensation Committee may consider additional grants to key employees for retention purposes on an ad hoc basis.

We maintain a tax-qualified retirement plan that provides eligible U.S. employees, including our NEOs, with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees may make voluntary contributions from their eligible pay, up to certain annual limits set by the Internal Revenue Code of 1986, as amended (the “Code”). In 2023, we used a matching formula for all participants in the 401(k) plan, including our NEOs, under which we matched $0.50 for each dollar contributed by a participant up to the first 6% of the participant’s deferral, to a maximum of $3,000 annually. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Code.

Historically, we have not provided perquisites or other personal benefits to our NEOs. However, in the future we may provide such items in limited circumstances, such as when we believe it is appropriate to assist an individual in the performance of their duties, to make our executives more efficient and effective, and to recruit, motivate or retain executives. All future practices with respect to perquisites or other personal benefits for executives must be approved and subject to periodic review by the Compensation Committee.

Effective October 2, 2023, the Compensation Committee approved a new Executive Compensation Clawback Policy (the “Required Clawback Policy”), which is designed to comply with, and will be interpreted in a manner consistent with, Section 10D of the Exchange Act and the applicable Nasdaq rules. Under the Required Clawback Policy, in the event of an accounting restatement due to our material noncompliance with any financial reporting requirement under applicable securities laws, including any required accounting restatement to correct a material error in previously issued financial statements, or that would result in a material misstatement if the error was corrected in the current period or left uncorrected in the current period, we must recover erroneously awarded performance-based compensation previously paid to our executive officers in accordance with the terms of the Required Clawback Policy. Furthermore, under the Required Clawback Policy, we are prohibited from indemnifying any executive officer or former executive officer against the loss of erroneously awarded performance-based compensation and from paying or reimbursing an executive officer for purchasing insurance to cover any such loss.

In addition, we also maintain clawback provisions that apply to all employees, including our NEOs, that receive equity awards under the 2023 PSP that allows the Board to recover any incentive-based compensation that was paid based on erroneous financial information reported under securities laws. Specifically, we may recoup any incentive compensation from any employee in the 2023 PSP if: (i) the employee engages in intentional misconduct pertaining to any financial reporting policy; (ii) there is a material negative revision of a financial or operating measure on the basis of which incentive compensation was awarded or paid to the employee; or (iii) the employee engages in any fraud, theft, misappropriation, embezzlement or dishonesty. Any recoupment will be made irrespective of whether the employee’s conduct contributed to the need for the restatement and/or revision. If triggered, to the fullest extent permitted by law we may require the employee to reimburse us for all or a portion of any incentive compensation received within the last 12 months from the date that the erroneous financial information was reported. The employee may also be required to remit to us any profits realized from the sale of our common stock within the last 12 months from the date the erroneous financial data was reported. The clawback amount will be calculated as the excess amount paid on the basis of the erroneous results.

Our insider trading policy prohibits our NEOs and directors from engaging in short sales, transactions in put or call options, hedging transactions, pledges, or other inherently speculative transactions relating to our common stock. In addition, our directors, NEOs and any person required to comply with the blackout periods and pre-clearance requirements under our insider trading policy are prohibited from pledging our securities as collateral for loans and may not hold our securities in margin accounts unless permitted by the Clearing Officer with the approval of the Chair of the Board, Chair of the Audit Committee, or the Board .

The Compensation Committee has reviewed our compensation policies and practices, in consultation with outside counsel, to assess whether they encourage employees to take inappropriate risks. After reviewing and assessing our compensation philosophy, terms and practices, including the mix of fixed and variable, short- and long-term incentives and overall pay, incentive plan structures, and the checks and balances built into, and oversight of, each plan and practice, the Compensation Committee determined that any risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on our Company as a whole. The Compensation Committee believes that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks; rather, it believes the mix of short-term compensation (in the form of salary and quarterly bonuses, if any, which are based on a variety of performance factors) and long-term compensation (in the form of stock options or RSU grants) prevents undue focus on short-term results and helps align the interests of our NEOs with the interests of our stockholders. In addition, our insider trading policy and prohibition against hedging and pledging of our stock protects against short-term decision making by our NEOs, directors and others identified as covered insiders under our insider trading policy. The Compensation Committee intends to conduct an annual review of our compensation-related risk profile to ensure that our compensation programs do not encourage excessive or inappropriate risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us.

1The dollar amounts in this column represent the aggregate grant date fair value of time-based RSU awards and PSU awards granted for the years indicated calculated in accordance with ASC 718, disregarding the estimate for forfeitures. For a discussion of the valuation methodology used, see Note 16, “Stock-Based Compensation” of the notes to consolidated financial statements included in Item 8 of our Annual Report on Form 10‑K for the year ended December 31, 2023, as filed with the SEC on February 9, 2024. Assuming that maximum performance is achieved, the value of the PSU awards subject to 2023 Annual CEO SMART Goals at the date of grant would have been as follows: Mr. Kothandaraman - $8,645,076; Ms. Yang- $2,809,650; and Mr. Ranhoff - $5,135,056. Mr. McNeil did not receive any PSU awards in 2023. With respect to the 2023 Annual CEO SMART Goal PSUs, grant date fair values, as computed in accordance with ASC 718 and presented in the table above and below under “2023 Grants of Plan Based Awards” are based upon the then probable outcome of the performance condition. The amounts reported in this column do not necessarily correspond to the actual value that may be realized from the awards by the NEOs.

1This column sets forth the target and maximum amount of each NEO’s annual performance-based bonus for the fiscal year ended December 31, 2023 under our quarterly cash performance-based bonus plan. Accordingly, the amounts set forth in this column do not represent actual compensation earned by our NEOs for the fiscal year ended December 31, 2023. The performance-based bonus is determined by multiplying the NEO’s base salary by (a) the applicable Bonus Percentage, (b) the Company Performance Factor (0 to 1.0x), (c) the Funding Factor (0 to 1.5x), and (d) the Individual Performance Factor (0 to 1.2x), for an overall maximum payout equal to 1.8 times target. For the actual quarterly performance-based bonuses paid to our NEOs for the fiscal year ended December 31, 2023, please refer to the “Summary Compensation Table” above. For a further discussion of the bonus program, please refer to the section entitled “Compensation Discussion and Analysis - 2023 Quarterly Performance Cash Bonus Program.”

3Amounts represent the grant date fair value of each stock award granted in 2023. In accordance with ASC 718, the grant date fair value per share subject to (i) each time-based vesting RSU and the at target number of PSUs that could be earned based on achievement of the 2023 Annual CEO SMART Goals is computed based on the closing price of our common stock as reported on the Nasdaq Global Market on the applicable grant date, and (ii) the PSUs that could be earned based on achievement of the relative TSR goals is computed based on the estimated fair value per share using a Monte Carlo simulation ($267.57 as of the March 8, 2023 grant date and $163.93 as of the July 21, 2023 grant date, as applicable). See Note 16, “Stock-Based Compensation” of the notes to consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 9, 2024, regarding assumptions underlying the valuation of stock awards and the calculation method. The grant date fair value computed in accordance with ASC 718 represents the amount we expect to expense for accounting purposes over the award's vesting schedule, and not the actual value that will be realized by the NEOs to the extent the awards vest. In addition to the level of performance achieved, the realized value of the PSUs earned will be determined by the price of our stock on the date any shares are issued at the end of the performance period, which may be more or less than the grant date fair value.

1The amount shown for value realized on exercise of stock options equals (i) the number of shares of our common stock to which the exercise of the stock option related, multiplied by (ii) the difference between the per-share market price of the shares on the date of exercise and the per-share exercise price of the option. If the stock acquired upon exercise was sold on the day of exercise, the market price was determined as the actual sales price of the stock. If the stock acquired upon exercise was not sold on the day of exercise, the market price was determined as the closing price of the stock on the Nasdaq Stock Market on the exercise date.

In March 2013, the Compensation Committee approved the Severance Plan for executive officers and other key employees, including the NEOs. Upon acceptance by a participant, the Severance Plan superseded and replaced certain existing severance agreements. The Compensation Committee has the authority to designate the participants in the Severance Plan and the level of benefits each such participant will be eligible to receive upon a qualifying termination of employment.

Under the Severance Plan, upon a termination of a participant’s employment by the Company without “cause” or the resignation by a participant for “good reason” (each, an “Involuntary Termination”), or upon an Involuntary Termination in connection with, or within 12 months following, a “change in control” (a “Change in Control Termination”), participants in the Severance Plan generally will be entitled to receive the following severance benefits:

In addition, unless otherwise provided in an agreement between a participant and us, if any payments or benefits that a participant would receive in connection with a change in control of us would constitute a “parachute payment” within the meaning of Section 280G of the Code, and such payments would be subject to the excise tax imposed by Section 4999 of the Code, then such payments will either be (1) provided to the participant in full or (2) reduced to such lesser amount that would result in no portion of such payments being subject to the excise tax, whichever amount after taking into account all taxes, including the excise tax, would result in the participant’s receipt, on an after-tax basis, of the greatest amount of such payments.

“Cause,” as determined by the Board acting in good faith and based on information then known to it, means the participant’s: (i) refusal or failure to perform the participant’s material, lawful and appropriate duties; (ii) material violation of Company policy or any written agreement between the Company and the participant; (iii) repeated unexplained or unjustified absence from the Company; (iv) intentional or negligent misconduct; (v) conviction of, or the entering of a plea of nolo contendere with respect to, any felony or a crime involving moral turpitude; (vi) unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the participant owes an obligation of non-disclosure as a result of the participant’s relationship with the Company; (vii) commitment of any act of fraud, embezzlement, misappropriation, dishonesty or breach of fiduciary duty against the Company that causes, or is likely to cause, material harm to the Company or its subsidiaries or is intended to result in substantial personal enrichment; or (viii) failure to cooperate with the Company in any investigation or formal proceeding, including any government investigation.

“Good Reason” means, without the participant’s written consent: (i) a material reduction or material adverse change in job duties, responsibilities or authority inconsistent with the participant’s position with the Company; provided, however, that any such reduction or change after a Change in Control (or similar corporate transaction that does not constitute a Change in Control) shall not constitute Good Reason by virtue of the fact that the participant is performing similar duties and responsibilities in a larger organization; (ii) a material reduction of the participant’s then current base salary, representing a reduction of more than 10% of the participant’s then current base salary; provided, that an across-the-board reduction in the salary level of all executive officers of the Company by the same percentage amount as part of a general salary level reduction shall not constitute such a material salary reduction; (iii) a material reduction of the participant’s target bonus opportunity; provided, that an across-the-board reduction in the target bonus opportunities of all executive officers of the Company shall not constitute such a material reduction in target bonus opportunity; (iv) the relocation of the principal place for performance of the participant’s duties to the Company to a location more than 50 miles from the Company’s then current location, which relocation is adverse to the participant, except for required travel on the Company’s business; (v) any material breach by the Company of the Severance Plan or any other written agreement between the Company and the participant; or (vi) the failure by any successor to the Company to assume the Severance Plan and any obligations under the Severance Plan; provided, that the participant gives written notice to the Company of the event forming the basis of the termination for Good Reason within 60 days after the date on which the Company gives written notice to the participant of the Company’s affirmative decision to take an action set forth in clause (i), (ii), (iii), (iv) or (v) above, the Company fails to cure such basis for the Good Reason resignation within 30 days after receipt of the participant’s written notice and the participant terminates his or her employment within 30 days following the expiration of the cure period.

3The amounts shown represent the portion of the RSU award that would have accelerated in connection with the termination event and are based on the intrinsic value of that portion as of December 31, 2023. These intrinsic values were calculated by multiplying (i) $132.14, the Nasdaq Stock Market closing price of a share of our common stock on December 29, 2023, the last trading day in fiscal 2023, by (ii) the number of stock units that would have vested on an accelerated basis on December 31, 2023.

4The amounts shown represent the target number of PSUs that would have accelerated in connection with the termination event and are based on the intrinsic value of those units as of December 31, 2023. These intrinsic values were calculated by multiplying (i) $132.14, the Nasdaq Stock Market closing price of a share of our common stock on December 29, 2023, the last trading day in 2023, by (ii) the target number of PSUs that would have vested on an accelerated basis on December 31, 2023.

To identify our median employee, we calculated the annual target total direct compensation for 2023 of each employee as of December 31, 2023. We identified the median compensated employee among an employee population of approximately 1,002 U.S. employees and 2,148 international employees. We did not exclude any employees whether pursuant to the de minimis exemption for foreign employees or any other permitted exclusion. For these purposes, annual target total direct compensation included each employee’s (a) base salary or base wages, (b) target cash incentive bonus opportunity and (c) the grant date fair value of equity awards. We selected this “consistently applied compensation measure,” because it reflects our primary compensation elements across our employee population. All amounts were annualized for regular full-time employees who did not work for the entire year of 2023. We did not apply any cost-of-living adjustment as part of the calculation. Further, in identifying the median employee, we converted compensation amounts paid in foreign currencies based on the applicable year-to-date average exchange rate as of December 31, 2023. As a result, we substituted an employee near the median whose compensation was viewed as more representative of our median employee.

In accordance with the rules set forth in Item 402(u) of Regulation S-K promulgated under the Exchange Act, we calculated the median employee’s annual total compensation in the same manner as the calculation of the CEO’s annual total compensation in the Summary Compensation Table. Our median employee’s annual total compensation for 2023 was $64,379. Our CEO’s annual total compensation for 2023, as reported in the Summary Compensation Table, was $19,527,534. Therefore, our CEO Pay Ratio for 2023 was approximately 303:1.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the Compensation Committee nor management of the company used the CEO Pay Ratio measure in making compensation decisions.

2“Compensation actually paid” to our CEO in each of 2023, 2022, 2021 and 2020 reflects the respective amounts set forth in this column of the table above, adjusted as set forth in the table below, as determined in accordance with SEC rules. The dollar amounts reflected in the table above do not reflect the actual amount of compensation earned by or paid to our CEO during the applicable year. For information regarding the decisions made by the Compensation Committee in regards to the CEO’s compensation for each fiscal year, please see the Compensation Discussion and Analysis section of the proxy statements reporting pay for the fiscal years covered in the table above.

3The dollar amounts reported in this column are the average amounts of total compensation reported for our NEOs as a group, other than our CEO in the Summary Compensation Table for the applicable fiscal years. The names of the NEOs (excluding our CEO) included for purposes of calculating the average amounts in each applicable year are as follows: (i) for 2023 Ms. Yang, Mr. Ranhoff and Mr. McNeil; (ii) for 2022 Ms. Yang, Mr. Branderiz, Mr. McNeil and Mr. Ranhoff; and (iii) for 2021 and 2020 Mr. Branderiz, Mr. McNeil and Mr. Ranhoff.

5For the relevant fiscal year, represents our TSR for the measurement periods ended on December 31 of 2023, 2022, 2021 and 2020 respectively. An investment of $100 is assumed to have been made in our common stock on December 31, 2019 all dividends were reinvested, and the performance of the investment is tracked through December 31, 2023. The information shown is historical, and stockholder returns over the indicated period should not be considered indicative of future stockholder returns or future performance.

6Represents comparison of cumulative TSR for our common stock and cumulative TSR for the Invesco Solar ETF for the period from December 31, 2019 to December 31, 2023. An investment of $100 is assumed to have been made in our common stock and in each index on December 31, 2019, all dividends were reinvested, and the relative performance of the investments are tracked through December 31, 2023. The information shown is historical and stockholder returns over the indicated period should not be considered indicative of future stockholder returns or future performance.

The Compensation Committee, with assistance from an external compensation consultant, has structured our executive compensation program to stress a pay-for-performance philosophy. The compensation opportunities provided to our NEOs are significantly dependent on our financial performance, the performance of our stock and rigorous corporate goals, which are intended to drive creation of sustainable stockholder value. The Compensation Committee will continue to emphasize what it believes to be responsible compensation arrangements that attract, retain and motivate high-caliber executive officers, and motivate those officers to achieve our short- and long-term business strategies and objectives.

You have the opportunity to vote “FOR” or “AGAINST” or to “ABSTAIN” from voting to approve, on an advisory basis, the compensation paid to our NEOs as disclosed in this proxy statement. In deciding how to vote on this proposal, we encourage you to consider our executive compensation philosophy and objectives, and the design principles and the elements of our executive compensation program. As described in this proxy statement, a guiding principle of our compensation philosophy is that compensation should be linked to performance and that the interests of our executives and stockholders should be aligned. Our compensation program is a mix of short- and long-term components, cash and equity elements and fixed and contingent payments in proportions we believe will provide the proper incentives, reward our NEOs and help us achieve our goals and increase stockholder value. For example:

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the philosophy, policies and practices described in this proxy statement. The compensation of our NEOs subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are focused on pay-for-performance principles and strongly aligned with our stockholders’ interests. Compensation of our NEOs is designed to enable us to attract and retain talented and experienced executives to lead us successfully in a competitive environment.

In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, our stockholders are also entitled to vote, on an advisory basis, on whether the advisory, non-binding vote on the compensation of our NEOs (commonly referred to as a “say-on-pay” vote), as required by Section 14A of the Exchange Act, should occur every one, two or three years. The vote on the frequency of the say-on-pay vote, just as with the say-on-pay vote itself, is advisory only, and it also is not binding on Enphase or on the Board. Although the vote is non-binding, the Compensation Committee and the Board will carefully consider the outcome of the vote when determining the frequency of future stockholder advisory votes to approve the compensation of our NEOs. Our stockholders voted on a similar proposal in 2018, with the majority voting to hold a say-on-pay vote every year.

After careful consideration, the Board has determined that a say-on-pay vote that occurs every year is the most appropriate alternative for our company at this time. The Board believes that an annual advisory say-on-pay vote will allow our stockholders to provide timely, direct input on our executive compensation philosophy, policies and practices as disclosed in the proxy statement each year. Therefore, the Board recommends that you vote for a “1 YEAR” frequency for the say-on-pay vote.

The option of once every 1 year, 2 years or 3 years that receives a majority of votes from the holders of shares present in person or virtually or represented by proxy and entitled to vote on the matter at the Annual Meeting will be determined to be the preferred frequency with which we are to hold “a "say-on-pay” vote. Because this proposal has multiple choices, it is possible that no choice will receive an affirmative vote of a majority of shares present in person or virtually or represented by proxy and entitled to vote on this matter at the Annual Meeting. In such case, the Compensation Committee and the Board will consider the choice that received the most votes present in person or virtually or represented by proxy and entitled to vote on this matter. This matter is non-routine; thus, if you hold your shares in street name, your broker may not vote your shares for you.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of Deloitte as our independent registered public accounting firm. The Board is submitting the selection of Deloitte to our stockholders for ratification as a matter of good corporate governance. However, the Audit Committee is not bound by a vote either for or against this proposal. The Audit Committee will consider a vote against Deloitte by the stockholders in selecting our independent registered public accounting firm in the future. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of Enphase and its stockholders.

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, Deloitte. These services may include audit services, audit-related services, tax services and other services. Pre-approval may be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual explicit case-by-case basis. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

As of March 22, 2024, the date of this report, the Audit Committee consisted of three members: Steven J. Gomo, who serves as the Chair of the Committee, Benjamin Kortlang and Richard Mora. Each member is an independent director under Nasdaq and SEC rules, and meets the standards for committee independence as set forth in our Corporate Governance Guidelines. The Audit Committee has the duties and powers described in its written charter adopted by the Board. A copy of the charter is available on our website at https://investor.enphase.com/corporate-governance.

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2023 with management. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the above, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

*The material in this report is not “soliciting material,” is furnished to, but not deemed “filed” with, the SEC and is not deemed to be incorporated by reference in any of our filings under the Securities Act or the Exchange Act, other than our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC on February 9, 2024, where it shall be deemed to be “furnished,” whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

1This table is based upon information supplied by officers, directors and principal stockholders and Schedules 13G filed with the SEC. Unless otherwise indicated in the footnotes to this table and subject to community property laws where applicable, we believe that each of the stockholders named in this table has sole voting and investment power with respect to the shares indicated as beneficially owned. Applicable percentage ownership is based on 135,988,561 shares of our common stock outstanding on March 19, 2024. In accordance with the rules and regulations of the SEC, in computing the number of shares of common stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of common stock subject to stock options or RSUs held by the person that are currently exercisable or exercisable (or issuable upon vesting of RSUs) within 60 days of March 19, 2024. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of such acquisition rights. As a result, the percentage of outstanding shares held by any person in the table below does not necessarily reflect the person’s actual voting power.

3Information provided is based solely on a Schedule 13G/A filed by the reporting person on February 6, 2024. The reporting entity is a parent holding company and has sole voting power with respect to 13,389,312 shares and sole dispositive power with respect to 14,437,662 shares, reporting on behalf of the following subsidiaries: BlackRock Life Limited, BlackRock Advisors, LLC, Aperio Group, LLC, BlackRock (Netherlands) B.V., BlackRock Institutional Trust Company, National Association, BlackRock Asset Management Ireland Limited, BlackRock Financial Management, Inc., BlackRock Japan Co.

3Includes 6,059,212 shares of common stock available for issuance under the 2021 Plan and 1,533,742 shares of common stock available for future purchase under the ESPP. The number of shares of common stock reserved for issuance under the ESPP automatically increases on each January 1, by the lesser of (i) 700,000 shares of common stock or (ii) 1.0% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, as determined by the Board.

The Audit Committee Charter provides that the Audit Committee will review and approve all related party transactions. This review will cover any material transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, and a related party had or will have a direct or indirect material interest, including, purchases of goods or services by or from the related party or entities in which the related party has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related party.

Except as disclosed below, since January 1, 2023, we have not been a party to any transactions in which the amount involved exceeded $120,000 and in which any of our executive officers, directors or holders of more than 5% of our capital stock, or any member of the immediate family of any of the above persons, had or will have a direct or indirect material interest, other than compensation arrangements with directors and executive officers, which are described where required under the “Executive Compensation” section of this proxy statement.

The members of the Board, our executive officers and persons who hold more than 10% of our outstanding common stock are subject to the reporting requirements of Section 16(a) of the Exchange Act, which requires them to file reports of ownership and changes in ownership with the SEC. To our knowledge, based solely upon a review of such reports that were filed with the SEC and written representations that no other reports were required to be filed in 2023, we believe that all required reports were timely filed, with the exception that, due to administrative error, (i) Mr. Ranhoff was late filing one Form 4 with respect to one transaction on the same date and (ii) Mr. Kothandaraman was late filing one Form 4 to report a transfer to a family trust.

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are Enphase stockholders will be “householding” our proxy materials. A single Notice of Internet Availability of Proxy Materials (“Notice”) will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice, please notify your broker or Enphase. Direct your written request to: Corporate Secretary, Enphase Energy, Inc., 47281 Bayside Parkway, Fremont, CA 94538 or call our Corporate Secretary at 1-707-774-7000. A separate copy of the Notice will be delivered promptly in response to any such request. Stockholders who currently receive multiple copies of the Notices at their addresses and would like to request “householding” of their communications should contact their brokers.

Under rules adopted by the SEC, Enphase Energy, Inc. (sometimes referred to in this proxy statement as “Enphase,” the “Company,” “we,” “our,” or “us”) has elected to provide access to our proxy materials over the internet. We are sending a Notice to our stockholders of record in connection with the solicitation of proxies by the Board for use at the Annual Meeting. All stockholders will have the ability to access the proxy materials at www.proxyvote.com or request a printed set of proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.

This year’s Annual Meeting will be held entirely online to protect the health and safety of our stockholders and employees and to facilitate stockholder participation. You will not be able to attend the Annual Meeting in person. The meeting will be held virtually on Wednesday, May 15, 2024 at 9:00 a.m. Pacific time via live audio-only webcast at www.virtualshareholdermeeting.com/ENPH2024. To attend the Annual Meeting, you will need the 16-digit control number included in the Notice or proxy card, or within the body of the email for electronic delivery recipients. Online log in will begin at 8:30 a.m. Pacific Time and you should allow ample time for the check-in procedures.

Our virtual Annual Meeting allows stockholders to submit questions and comments during the Annual Meeting. You may submit questions during the Annual Meeting in the question box provided at www.virtualshareholdermeeting.com/ENPH2024. All directors and key executive officers are expected to be available to answer questions. We plan to answer questions pertinent to company matters as time allows during the meeting. Questions that are substantially similar may be grouped and answered once to avoid repetition. Stockholder questions related to personal or customer-related matters, that are not pertinent to annual meeting matters, or that contain derogatory references to individuals, use offensive language, or are otherwise out of order or not suitable for the conduct of the annual meeting as determined by the chair will not be addressed during the meeting.

If, on March 19, 2024, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote by internet before or during the Annual Meeting, by telephone or by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the proxy card or vote by internet or by telephone before the Annual Meeting to ensure your vote is counted.

If, on March 19, 2024, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. Simply follow the voting instructions in such Notice to ensure that your vote is counted. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other nominee regarding how to vote the shares in your account. You are also invited to virtually attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares by internet during the Annual Meeting unless you request and obtain a valid 16-digit control number from your broker, bank or other nominee.

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine” under the rules of the New York Stock Exchange (NYSE). Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. These un-voted shares are counted as “broker non-votes.” Proposal 1 (election of the nominee for director); Proposal 2 (advisory vote on compensation of named executive officers); and Proposal 3 (advisory vote on the frequency of stockholder advisory votes on executive compensation) are considered “non-routine” matters under NYSE rules, and we therefore expect broker non-votes to exist in connection with those proposals. Proposal 4 (ratification of the selection of our independent registered public accounting firm) is expected to be a “routine” matter.

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing to and received by our Corporate Secretary at 47281 Bayside Parkway, Fremont, CA 94538 by December 5, 2024, and must comply with all requirements of Rule 14a-8 promulgated under the Exchange Act. If you wish to submit a proposal that is not to be included in next year’s proxy materials, but that may be considered at the 2025 Annual Meeting of Stockholders, you must do so in writing following the above instructions not earlier than the close of business on January 15, 2025 and not later than the close of business on February 14, 2025. We advise you to review our Bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations, including the different notice submission date requirements in the event the 2025 Annual Meeting of Stockholders is held more than 30 days before or after May 15, 2025. The section titled “Nominating and Corporate Governance Committee” in this proxy statement provides additional information on the director nomination process. In addition to satisfying the deadlines in the advance notice provisions of our Bylaws, a stockholder who intends to solicit proxies in support of nominees submitted under these advance notice provisions must provide the notice required under Rule 14a-19 to our Corporate Secretary no later than March 17, 2025; provided that, in the event the 2025 Annual Meeting of Stockholders is held more than 30 days before or after May 15, 2025, such notice must be provided by the later of 60 days prior to the date of the 2025 Annual Meeting of Stockholders or 10 days following the day on which we first publicly announce the date of the 2025 Annual Meeting of Stockholders.

Proposal Description

Vote Required for Approval

Effect of Abstentions

Effect of Broker Non-Votes

Election of Class III Nominees

Nominees receiving the most “FOR” votes will be elected; withheld votes will have no effect. Note, however, that our Corporate Governance Guidelines require that any nominee in an uncontested election who does not receive a majority of the votes cast shall submit an offer of resignation to the Nominating and Corporate Governance Committee.

Not applicable

No effect

Advisory approval of the compensation of our named executive officers

“FOR” votes from the holders of a majority of shares present in person or virtually or represented by proxy and entitled to vote on the matter. However, this proposal is advisory and non-binding upon us.

Against

No effect

Advisory vote on the frequency of stockholder advisory votes on executive compensation

The frequency receiving votes from the holders of a majority of shares present in person or virtually or represented by proxy and entitled to vote on the matter. However, this proposal is advisory and non-binding upon us.

Against each of the proposed voting frequencies

No effect

Ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024

“FOR” votes from the holders of a majority of shares present in person or virtually or represented by proxy and entitled to vote on the matter.

Against

Not applicable

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you virtually attend the Annual Meeting and vote by internet during the Annual Meeting by visiting www.virtualshareholdermeeting.com/ENPH2024. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present in person or virtually during the Annual Meeting or represented by proxy may adjourn the meeting to another date.

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8‑K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.
