Currently, the Board consistsstatistics as of members with a wide variety of skills, industry experiences and backgrounds. We are committed to diversity and inclusion at every level of MPS, including the Board. Our Nominating Committee has been actively recruiting a female Board member, with the assistance of the full Board, our management team and a retained search firm. We believe a diverse, balanced and cohesive Board is critical in facilitating strong oversight, as well as supporting the achievement of MPS’s objectives, including its strategic priorities to improve long-term operational and financial performance and enhance stockholder interests. Our philosophy ensures each Board member’s individual interests are represented and their perspectives and opinions are valued. To accomplish this goal, the Board believes it is important to conduct in-person meetings (in addition to virtual meetings) in order to have the necessary interactions to evaluate the candidates, review their qualifications thoroughly, build trust and develop a strong relationship with existing Board members. This important process has been made more challenging by the COVID-19 pandemic, as the majority of candidates considered to date and many of our Board members are located in Asia and Europe where there are strict travel restrictions and shelter-in-place orders. We recognize the importance of moving the recruiting process forward and are taking practical steps to reach the final stage. The Board is fully committed to completing its search to appoint one female Board member before the end of 2021.April 29, 2024:

Should the Board determine that it remains in the best interests of MPS and its stockholders that the Chief Executive Officer serve as Chairman, the independent members of the Board then elect a Lead Independent Director.

The Board has currently determined that it is in the best interests of MPS and ourits stockholders to have Michael Hsing, our President and Chief Executive Officer, serve as Chairman, coupled with an active Lead Independent Director. As such, Mr. Hsing holds the position of Chairman, President and Chief Executive Officer, and the Board has designated one of the independent directors, Mr. Herbert Chang, as the Lead Independent Director. Our Lead Independent Director is appointed by the Board on an annual basis. The Board believes our leadership structure, with its strong emphasis on Board independence, an active Lead Independent Director, and strong Board and committee involvement, provides sound and robust oversight of management, and provides a counterbalance to the management perspective provided by Mr. Hsing during Board deliberations. 

The Board considers and discusses the Board leadership structure every year. As part of this evaluation process, the Board reviews its leadership structure and whether combining or separating the roles of Chairman and CEO is in the best interests of the CompanyMPS and our stockholders. The Board also considers:

Should the Board determine that it remains in the best interests of the Company and its stockholders that the Chief Executive Officer serve as Chairman, the independent members of the Board then elect a Lead Independent Director.

WeWhile we recognize that different board leadership structures may be appropriate for different companies. Wecompanies, we believe that our current Board leadership structure is optimal for us. Our leadership structure demonstrates to our employees, suppliers, customers, stockholders and other stakeholders that we are governed by strong, balanced leadership, with a single person setting the tone and consistent message for the Board and management and having primary responsibility for managing our day-to-day operations, with appropriate oversight and direction from our Lead Independent Director and other independent directors. This message is increasingly important as we continue to seek to achieve business success through new product releases and gaining market share in our industry.business growth. We also believe that our leadership structure sends the message that we value strong, independent oversight of our management operations and decisions in the form of our Lead Independent Director.Director and other independent directors. Further, having a single leader for both MPS and the Board eliminates the potential for strategic misalignment or duplication of efforts, and provides clear leadership for us.

Benefits of Combined Leadership Structure. The Board believes that MPS and our stockholders have been best served by having Mr. Hsing in the role of Chairman and Chief Executive Officer for the following reasons:

Lead Independent Director Responsibilities. As discussed above, the positions of Chairman of the Board, President and Chief Executive Officer are held by Mr. Hsing, and the Board has appointed a Lead Independent Director, Mr. Chang.  Mr. Chang’s primary roles and responsibilities as the Lead Independent Director include:

Our independent directors meet in executive session during a portion of every regularly scheduled Board meeting,or committee meetings, and otherwise as needed. Our Lead Independent Director presides over meetings of our independent directors and we believe that these meetings help to ensure an appropriate level of independent scrutiny of the functioning of MPS and the Board.

Board Oversight of RiskRisks

The Board is primarily responsible for the oversight of risks that could affect MPS. Our senior management team, which conducts our day-to-day risk management, is responsible for assisting the Board with its risk oversight function. The Board believes that a fundamental part of risk management is understanding the risks that we face, monitoring these risks, and adopting appropriate controls and mitigation activities for such risks. We believe that the risk management areas that are fundamentalcritical to theour long-term success of our enterpriseprimarily include the areas of product development, supply chain and quality, regulations and legal compliance, ESG, executive compensation programs, sales and promotion,promotions, and business development, as well as protectingprotection of our assets (financial, intellectual property and information, including cybersecurity), all of which are managed by senior executive management reporting directly to our Chief Executive Officer. Our Board members have extensive experience in risk oversight arising from their current or prior experience as a Chief Executive Officer, Chief Financial Officer,chief executive officers, chief financial officers, chief information officers, as well as other senior leadership positionpositions or board membermembers of other companies with responsibility for risk oversight obligations. As such, the Board believes that its members are qualified and experienced at identifying and addressing risk throughout MPS’sour operations.

The Board’s oversight is conducted principally through committees of the Board, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees, butWhile the full Board has retained responsibility for general oversight of risk.risk, the Board’s oversight is conducted principally through the committees of the Board. The Board satisfies its responsibility by requiring each committee chair to regularly report regarding the committee’s considerations and actions, including risk oversight, as well as by requiring officers responsible for oversight of particular risks within MPS to submit regular reports. As these reports are submitted independent of review by Mr. Hsing, our President, Chief Executive Officer and the Chairman of the Board, the Board believes that its leadership structure has no impact on the conduct of its risk oversight function has no impact on the Board’s leadership structure other than to reinforce the involvement of the Board in ongoing management of MPS.

The following table outlines the specific risk oversight responsibilities of each committee:

Our senior management team, which conducts our day-to-day risk management, is responsible for assisting the Board and the committees with its risk oversight function. At its regularly scheduled meetings, the Board and the committees require officers responsible for oversight of particular risks to submit updates and reports on business matters including operational and ESG issues, financial results, cybersecurity and information security, and business outlook and strategy. These updates enable our Board and the committees to discuss enterprise risks with our senior management on a regular basis, including as a part of its annual strategic planning process and annual budget review.

In addition to requiring regular reporting from committees and officers, the Board also hearsreceives reports from third-party advisors in order to maintain oversight of risks that could affect us, including our independent auditors, outside counsel, compensation consultants and others. These advisors are consulted on a periodic basis, and as particular issues arise, in order to provide the Board and the committees with the benefit of independent expert advice and insights on specific risk-related matters.

At its regularly scheduled meetings, the Board also receives management updates on the business, including operational and environmental, social and governance (“ESG”) issues, financial results, cybersecurity and information security matters, and business outlook and strategy.  These updates enable our Board to discuss enterprise risks with our senior management on a regular basis, including as a part of its annual strategic planning process and annual budget review. For a discussion of the Board’s oversight of our ESG compliance efforts, refer to the section “Corporate Social Responsibility.”

Our Audit Committee assists the full Board in its oversight of risk by discussing with management our compliance with legal and regulatory requirements, our policies with respect to risk assessment and management of business risks that may affect us, including risks related to information technology and cybersecurity, and our system of disclosure control and system of controls over financial reporting.  Risks related to our company-wide compensation programs are reviewed by our Compensation Committee. For more information on the Compensation Committee’s compensation risk assessment, see the section “Named Executive Officer Compensation – Compensation Risk Management.” Our Nominating Committee provides compliance oversight and reports to the full Board on compliance and makes recommendations to our Board on corporate governance matters, including director nominees, the determination of director independence, and board and committee structure and membership.

We believe the division of risk management responsibilities described above is an effective approach for addressing the risks facing us and that the Board leadership structure supports this approach.

We applied our expertise in power management and motor controls toward a solution that can safely and easily automate a manual resuscitator when a full ICU ventilator may not be available.

Goals for 2021 and Beyondstockholders:

What We Heard from Stockholders

Focus on Board DiversityHow We Responded

We believe diversity drives innovation and is key to our success. Currently, the Board consists of members with a wide variety of skills, industry experiences and backgrounds. We are committed to diversity and inclusion at every level of MPS, including the Board. Our Nominating Committee has been actively recruiting a female Board member, with the assistance of the full Board, our management team and a retained search firm. We believe a diverse, balanced and cohesive Board is critical in facilitating strong oversight, as well as supporting the achievement of MPS’s objectives, including its strategic priorities to improve long-term operational and financial performance and enhance stockholder interests. Our philosophy ensures each Board member’s individual interests are represented and their perspectives and opinions are valued. To accomplish this goal, the Board believes it is important to conduct in-person meetings (in addition to virtual meetings) in order to have the necessary interactions to evaluate the candidates, review their qualifications thoroughly, build trust and develop a strong relationship with existing Board members. This important process has been made more challenging by the COVID-19 pandemic, as the majority of candidates considered to date and many of our Board members are located in Asia and Europe where there are strict travel restrictions and shelter-in-place orders. We recognize the importance of moving the recruiting process forward and are taking practical steps to reach the final stage. The Board is fully committed to completing its search to appoint one female Board member before the end of 2021.

ESG

We should establish clear commitments to addressing climate risks and setting rigorous sustainability goals, and greater link between executive compensation and achievement of ESG goals.

We made significant progress related to our ESG program in 2023. We completed our Scope 1 and Scope 2 GHG emissions inventory and set goals to reduce our GHG emissions by 40% by 2030 and power our operations with at least 75% renewable electricity by 2026.

Commitment to Environmental Initiatives

We take environmental stewardship seriously, and the Board recognizes the opportunities and importance of implementing measures to reduce our overall impact on the environment. In February 2021, as part of our commitment to promoting environmental sustainability, the Compensation Committee implemented changes to our executive equity compensation program to include long-term performance conditions with a three-year performance period that are tied directly to the following environmental metrics:

The Compensation Committee believes that incorporating key environmental sustainability initiatives into our annual incentive equity awards for the NEOs will help drive our efforts in these important areas of focus for MPS.

PROPOSAL TWO

All such services for 20202023 and 20192022 were pre-approved by the Audit Committee. 

Change in Independent Registered Public Accounting Firm

As previously reported in our Current Report on Form 8-K (the “Current Report”) dated March 22, 2019, following a comprehensive process, the Audit Committee dismissed Deloitte & Touche as our independent registered public accounting firm on March 18, 2019.

Deloitte & Touche’s reports on our consolidated financial statements as of and for the years ended December 31, 2018 and December 31, 2017 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In addition, the audit reports of Deloitte & Touche on the effectiveness of internal control over financial reporting as of December 31, 2018 and December 31, 2017 did not contain any adverse opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the years ended December 31, 2018 and December 31, 2017, and the subsequent interim period through March 18, 2019, there were (i) no “disagreements” as that term is defined in Item 304(a)(1)(iv) of Regulation S-K, between us and Deloitte & Touche on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte & Touche, would have caused Deloitte & Touche to make reference to the subject matter of the disagreement in their reports, and (ii) no “reportable events” as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

We provided Deloitte & Touche with a copy of the disclosures made in the Current Report. In addition, we requested that Deloitte & Touche furnish a letter addressed to the SEC stating whether or not it agreed with the statements made in the Current Report. A copy of Deloitte & Touche’s letter dated March 22, 2019 was attached as Exhibit 16.1 to the Current Report.

During the fiscal years ended December 31, 2018 and December 31, 2017, and the subsequent interim period through March 18, 2019, neither we nor anyone acting on our behalf has consulted with Ernst & Young with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, and neither a written report nor oral advice was provided to us that Ernst & Young concluded was an important factor considered by us in reaching a decision as to any accounting, auditing, or financial reporting issue or (ii) any matter that was either the subject of a “disagreement” or “reportable event” as those terms are defined in Item 304(a)(1) of Regulation S-K.

PROPOSAL THREE

ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

As required under Section 14A of the Securities Exchange Act, of 1934, we are asking stockholders to again cast an advisory (non-binding) vote on the following resolution at the Annual Meeting:

RESOLVED, that, on an advisory basis, the compensation of our named executive officers, as disclosed in the Compensation Discussion and Analysis, compensation tables and related narratives and descriptions of this Proxy Statement for the Annual Meeting, is hereby APPROVED.

This advisory vote, commonly known as a “say-on-pay” vote, gives our stockholders the opportunity to express their views about the compensation we paid to our named executive officers, in the prior year, as described in this Proxy Statement.  Before stockholders vote on this proposal, they should review the Compensation Discussion and Analysis in this Proxy Statement and the tabular and narrative disclosure that follows it. We currently conduct say-on-pay votes every year. TheTherefore, the next say-on-pay vote is expected to occur at the 20222025 annual meeting of stockholders.

We are committed to responsible compensation practices and structures. As described more fully in the Compensation Discussion and Analysis section of this Proxy Statement, the primary goal of our executive compensation program is the same as our goal for operating MPS — to create long-term value for our stockholders. To achieve this goal, we have regularly sought out the feedback of our major stockholders over the past several years to hear their suggestions on how we can better achieve our primary compensation goal. After taking their feedback into consideration, we have continued to update our compensation program for our named executive officers, implementing those recommendations of our stockholders that the Compensation Committee believes will help us create long-term value for our stockholders. We believe these annual reviews of our programs, in coordination with our conversations with our stockholders, allow us to motivate and reward our executives for sustained financial and operating performance and leadership excellence, to align their interests with those of our stockholders, and to encourage them to remain with us for long and productive careers.

Stockholders may vote “for” or “against” the resolution or abstain from voting on the resolution.  The affirmative vote of a majority of the shares of stock entitled to vote thereon which are present in person viaby virtual attendance at the Annual Meeting or represented by proxy at the Annual Meeting is required to approve, on an advisory basis, the compensation of our named executive officers. The result of the say-on-pay vote will not be binding on us, the Board or the Compensation Committee. However, we value the views of the stockholders. The Board and the Compensation Committee will review the results of the vote and expect to take them into consideration in addressing future compensation policies and decisions.

FOR THESE REASONS, THE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THE COMPENSATION DISCUSSION AND ANALYSIS, COMPENSATION TABLES AND RELATED NARRATIVES AND DESCRIPTIONS OF THIS PROXY STATEMENT FOR THE ANNUAL MEETING.

Executive Summary

Impact of COVID-19Financial and Business Performance Highlights:

ThroughoutThe Compensation Committee has focused our executives on accountability in revenue, operating income and earnings, as well as maximizing stockholder return through the COVID-19 pandemic in 2020, management’s primary focus was to continue to execute MPS’s business plan and mitigate the effect of the pandemic on our financial position and business operations. The Board and its committees received regular updates from management on our pandemic response and closely monitored our efforts to follow governmental guidelines and ensure the safetystructure of our employees, suppliers and customers. Since March 2020, our employees inexecutive compensation program. In 2023, despite the United States and certain international locations have been working remotely, and we have temporarily prohibited most business travel. Despite the challenges of the pandemic and an uncertain economy, demand for our products continued to grow, and weglobal economic uncertainty, MPS achieved record revenue andof $1.8 billion. This was our 12th consecutive year of revenue growth.

Our revenue grew 1.5% from the prior year, compared with the analog industry’s 9% decrease reported by the Semiconductor Industry Association (“SIA”). Our financial results in 2020. Performance targets under our executive compensation program were established by the Compensation Committee in February 2020,are summarized as follows (in millions, except per-share amounts and no downward adjustments to these performance targets were made due to the pandemic.percentages):

In 2023, we continued to execute our long-term strategy by bringing innovative new products to market, expanding design wins across our broad base of customers and diversifying our operations, some of which are highlighted below:

Cash Dividends and Stock Repurchases:

Due to our continued strong performance, we have increased the amount of our dividends paid to stockholders over the last few years. The following table summarizes our cash dividend payments to our stockholders in the past three years (in thousands, except per-share amounts):

In February 2024, the Board approved an increase in our quarterly cash dividends to $1.25 per share.

In October 2023, the Board approved a stock repurchase program authorizing us to repurchase up to $640 million in the aggregate of our Common Stock through October 2026. We repurchased approximately 7,000 shares of our Common Stock for an aggregate purchase price of $3.7 million in 2023.

Total Stockholder Return (“TSR”):

Our one-year and three-year TSR outperformed our peer group, the PHLX Semiconductor Sector Index (the “PHLX Index”) and the S&P 500 Index:

Market Capitalization:

Our strong financial performance in the past several years has translated to a significant increase in our market capitalization, surpassing $30 billion for the first time in 2023. The following chart illustrates Mr. Hsing’s compensation (as reported in the 2023 Summary Compensation PhilosophyTable) compared to our market capitalization in the past three years: 

Compensation Philosophy:

The primary objective in designing our compensation program for our NEOs is the same as the primary objective for operating MPS — to create long-term value for our stockholders. To achieve this goal, we have designed and implemented our compensation programs for our NEOs to:

Each one of our executive compensation elements fulfills one or more of our performance, alignment and retention objectives. These elements primarily consist of salary, long-term equity awards and short-term cash incentive compensation, as well as severance benefits and broad-based employee benefits. In deciding on the type and amount of compensation for each executive, we focus on both current pay and the opportunity for future compensation. We believe that maintaining a balance of short-term and long-term compensation elements encourages decision-making that optimizes short-term results and, at the same time, advances our long-term goals. We combine the compensation elements for each NEO in a manner we believe optimizes the executive’s overall contribution to us and our stockholders.

Our Compensation Practices Are Built on Stockholder Feedback and RequestsRequests:

At the 20202023 Annual Meeting of Stockholders, we received approximately 98% of the votes cast by 96%57% advisory approval of our stockholders were in favor of our executive compensation program.NEOs’ compensation. At the 20192022 Annual Meeting of Stockholders, we received approximately 99% of the votes cast by 96%72% advisory approval of our stockholders were in favor of our executive compensation program.NEOs’ compensation. At the 20182021 Annual Meeting of Stockholders, we received approximately 97% of the votes cast by 96%88% advisory approval of our stockholders were in favor of our executive compensation program.NEOs’ compensation. While these say-on-pay votes are only advisory and not binding on us, the Compensation Committee discusses the vote results each year with our independent compensation consultant.consultant and the Board.

Our management team continued the practice of reaching out to our most significant stockholders from time to time to discuss how those stockholders view our executive compensation program, and what kind of changes they would like to see implemented in future years. Many of our stockholders were pleased with our strong financial performance and execution, as well as the progress we have made on our ESG program which demonstrates our commitment to environmental issues. Based on the overwhelming multi-year support by themost recent feedback we have received from our stockholders, in favor of our pay-for-performance compensation structure, the Compensation Committee decidedmade the following significant changes to continue to grant equity awards based on performance conditions under the executive compensation program in 2020. program:

See “Stockholder Engagement” for further discussion.

In the past several years, we have continued to improve our executive compensation policies and programs, incorporating the suggestions of our stockholders. We believe these improvements, as highlighted below, have supported our financial and strategic successes in the last several years.

Our success is built on a strong pay-for-performance culture within our entire organization, including among our rank-and-file employees in addition to our CEO and other NEOs. The Compensation Committee believes that a performance-based compensation program based on a small guaranteed pay and a significant upside for our executives and employees provides strong incentives that will generate more robust returns to our stockholders than more traditional compensation packages.

For 2023, a small portion of the total compensation packages for the NEOs was a guaranteed component, consisting of base salary that was among the lowest in the semiconductor industry. The remaining target compensation, consisting of short-term cash incentives and long-term equity incentive awards, is at risk and directly linked to performance, as outlined in the graphs below:

In order to earn the maximum payout for the at-risk awards, the NEOs must exceed targeted performance. In 2023, the total compensation for the NEOs were significantly lower (by as much as 33%) compared to the prior year primarily because the maximum non-GAAP operating income goals were not achieved under the short-term incentive plan, which resulted in a payout that was well below the maximum payout opportunity. See “Analysis of 2023 Compensation Elements” for further discussion.

We believe this pay structure is a more responsible approach because it focuses on performance and accountability. In the years when the NEOs earned the maximum payout, we also achieved significant business growth and outperformed the market and our peers. In the years when we did not meet the rigorous performance goals, the NEOs were not able to earn the maximum payout. This compensation philosophy fully demonstrates a direct correlation between performance and pay.

The following graph shows the three-year history of our performance in revenue, GAAP operating income and non-GAAP operating income, which demonstrates a balance of our overall financial health, compared to our CEO’s total compensation (as reported in the 2023 Summary Compensation Table).

______________

We believe our cumulative TSR performance over the past ten years, as illustrated below, demonstrate the effectiveness of our performance-based compensation program in motivating our NEOs to build a sustainable business model and to focus on long-term value creation for our stockholders.

Our Compensation Committee has capped maximum cash payouts under our annual non-equity incentive plans at 400% of target for all of the NEOs.

Stock Performance:

Our one-year total stockholder return (“TSR”) was approximately 107% and our three-year TSR was approximately 236%, as shown in the graphs below in comparison to our peer group and the Philadelphia Stock Exchange (“PHLX”) semiconductor sector index:

Market Capitalization:

Our strong financial performance in the past several years has led to a significant increase in our market capitalization, surpassing $15 billion in 2020. Because a significant portion of our NEOs’ total compensation in the past several years has been in the form of market-based stock units with stock price performance components, the value of our NEOs’ compensation is closely tied to our market performance. The following chart illustrates our CEO’s compensation (as reported in the 2020 Summary Compensation Table) compared to our market capitalization in the past three years:

In October 2023, the Board adopted the Compensation Recoupment Policy to comply with Section 10D of the Exchange Act and the NASDAQ listing standards as mandated by the Dodd-Frank Act. The policy provides for the recovery, in the event of a required accounting restatement, of certain variable incentive-based cash and equity compensation received by current or former executive officers (within the meaning of Rule 16a-1(f) under the Exchange Act, and including our NEOs) that is based on erroneously reported financial information during a three-year recovery period preceding a financial restatement, subject to limited exceptions, to the extent that such payments exceed the amount of performance-based incentive compensation that would have been received by such executive officers during such period had they been determined based on the relevant restated amounts. The recovery of incentive-based compensation is required regardless of whether the executive officer engaged in any misconduct or was at fault for the restatement. A copy of the policy is filed as Exhibit 97.1 to our 2023 Annual Report.

Since 2008, we have not adopted any new employment agreements (or modified any existing employment agreements) to provide for tax gross-ups to our officers.

We have a policy prohibiting our directors, officers (including our NEOs), and other employees from engaging in certain hedging and monetization transactions with respect to our stock that they hold without prior approval by our Chief Compliance Officer. The policy also prohibits our directors and officers (including our NEOs) from engaging in any short sales of our stock. In summary, we regularlyaddition, our directors and officers are prohibited at all times from holding our stock in a margin account and from pledging our stock as collateral.

We routinely engage with our stockholders to exchange ideas on our existing executive compensation programs and potential future programs. We listen to their feedback and carefully consider it. Our engagement with stockholders does not begin and end with the say-on-pay vote – that vote is just one part of a larger dialogue and partnership we have with our investors.

2020 Financial and Business Performance Highlights

As noted above, the Compensation Committee has focused our executives on accountability in revenue, operating income and earnings, as well as maximizing stockholder return through the structure of our executive compensation program. In 2020, despite the COVID-19 pandemic which negatively affected the global economy, we achieved record results in revenue and other key financial metrics. Our financial results are summarized as follows (in millions, except per-share amounts and percentages):

Our revenue growth rate of 34% in 2020 outperformed the analog industry’s 3% reported by the Semiconductor Industry Association (the “SIA”). We also achieved significant success in our targeted end markets in 2020 as follows:
