RESULTS AT A GLANCE

2021 HIGHLIGHTS

MESSAGE FROM OUR CHAIRMAN

Dear Stockholders:

In 2021, Mueller Industries delivered its second consecutive year of record earnings amidst a macroeconomic environment marked by the ongoing pandemic, supply-chain disruptions and a difficult labor market. At Mueller, we strive to “Be Flexible and Receptive to Change,” and that approach proved vital to our success.

Our results demonstrate what our Company can accomplish when its potential is unleashed and we fire on all cylinders. Favorable market conditions led to robust demand levels in all of our businesses. Our manufacturing facilities operated at very high levels of efficiency and productivity, and our sales and marketing teams proactively responded to significant levels of inflation across our supply chain by swiftly implementing necessary price increases.

Having now achieved our fourth consecutive year of double digit operating earnings growth, we remain committed to and focused on executing our long term strategic plan. Our priorities are to protect and expand our core businesses, grow our downstream value-added businesses, and to plant seeds in innovative products and emerging technologies. In so doing, we will continue to drive growth and create value for our stockholders.

Below are just a few examples of our achievements during the past year:

Strategic Execution

Expansion

In January 2021, we acquired the former Hart & Cooley flexible duct business, which complements the ATCO Flex business we acquired in 2018. We reintroduced it to the market as “H&C Flex” and the business has significantly benefitted from the implementation of our culture and best practices. Production continues to improve, and we are confident that H&C Flex will be an important supplier to the markets we serve, and an even more positive contributor to our 2022 results.

In December, we acquired the bank debt of the Mueller Middle East copper tube mill in Bahrain, in which we previously held a minority interest. The business had underperformed since commencing operations in 2018, and as such, required a new leadership team and vision. After acquiring the debt on favorable terms, we have restructured the business and accelerated investment plans so that the business can operate with a more stable and efficient capital platform. We anticipate that the business will be profitable in early 2022.

Innovation

We spent the full year installing our state of the art copper scrap refining system at our Mueller Europe operation in the United Kingdom. The project will be completed by the end of the second quarter of 2022, and will serve as the United Kingdom’s only copper refinery. This investment will not only deliver important financial benefits to the Company, but it will also contribute to our sustainability goals. Specifically, the refining system will enable us to fully supply the needs of our mill by utilizing local copper scrap, thereby reducing our reliance upon imported raw materials (which are costly to mine and transport), and mitigating the costs associated with exporting copper scrap to be refined in other countries. Establishing such a circular economy is a vital benefit to both our Company and the communities in which we operate.

In today’s tight labor environment, contractors across a wide spectrum of vocations are seeking products that reduce labor hours, training and skill requirements. This trend has paved the way for a rapidly evolving innovation in piping systems called “press fittings,” which offer a way to join pipes mechanically (i.e., without a torch or flame). Since we first introduced our line of plumbing press technology in 2016, it has achieved double digit earnings growth on an annual basis. In late 2021, building on this momentum and in direct response to our customers’ needs, we launched two new press product lines: our new “Carbon Steel Press Fitting” for use in natural gas systems, non-potable water applications and fire sprinkler systems, and our proprietary copper “ACR Press Fitting,” which is used systems that carry refrigerant. As a global leader in air conditioning and refrigeration pipe and joining products, we are excited to bring this new functionality to our customers to help them adapt to these ongoing challenges.

Optimization

Although growth is our focus, we continually evaluate our portfolio of businesses to ensure they remain aligned with our long term objectives. Should an investment no longer fit within our long term growth strategy, or remain on track to achieve our high standard of financial and operational performance, we consider alternate courses of action. In 2021, we exercised the opportunity to divest of four businesses that while profitable, were not positioned to meet our long term expectations. The proceeds from these divestitures were substantial relative to the performance of the businesses, and the gains from these divestitures contributed $57.8 million of our operating income in 2021.

Financial Performance

Sales in 2021 grew by $1.4 billion, or 60%, to $3.8 billion. Organic sales increased in all three business segments as market demand outpaced capacity for the majority of the year in every one of our businesses. COMEX copper rose 51% over the prior year, thereby contributing to our increased revenues, as we successfully passed these costs through to our customers in a timely manner. Moreover, growth through acquisitions (including the H&C Flex acquisition, and our August 2020 acquisition of the Kessler Sales and Distribution business) also contributed to the overall increase in sales.

Operating income in 2021 reached $656 million, a $410 million increase over the prior year. Adjusting for the gains from the proceeds of the four divestitures, the improvement was $352  million. This growth was fueled by our strong sales, combined with a 400 basis point expansion of our gross margin stemming from effective price management in response to wage inflation and escalating consumable, freight and distribution costs.

In 2021, we generated $312 million in cash from operations, fueled by the strength of our operating performance, after investing an additional $212 million in working capital to support our growth. This robust cash generation was the highest in our history, and paved the way for us to opportunistically pay down $330 million of debt, fund $62 million in acquisitions and capital expenditures, and return $29 million to our valued stockholders in the form of quarterly dividends. We closed the year with a strong balance sheet, including $88 million of cash on hand and zero net debt.

While we have ambitious goals for the future, we continue to employ a prudent and balanced approach for managing our capital allocation and risk, prioritizing re-investment in our operations and acquisitions to drive growth, as well as stockholder returns. Given our strong cash generation and healthy balance sheet, we recently announced a 92% increase in our regular quarterly dividend for 2022 from $0.13 per share to $0.25 per share. On an annualized run rate, this increases our dividend from $0.52 per share to $1.00 per share.

Sustainability

Ensuring the safety, health and well-being of our employees is the most critical pillar of our business and values. In 2021, despite increased staffing at all locations to support ongoing demand, our OSHA incidence rate remained at our lowest level of all time. To better demonstrate our longstanding commitment to the critical environmental, social and governance measures that we and our stakeholders value, we recently published our inaugural Sustainability Report. Our newly updated 2022 Sustainability Report is also now available on our website at www.muellerindustries.com/about-us/sustainability/, and we invite you to follow our progress in these areas.

Outlook and Conclusion

We look to the future with high expectations for our Company. At our core, we are a manufacturer, and the diverse array of products we produce and distribute are essential in supporting, among other critical infrastructure needs, clean air and water applications, food preservation, medical and health related technologies, transportation and climate comfort. Our products are integral to residential home construction, but they are used even more extensively in the schools, firehouses, convenience stores, supermarkets, hospitals, office buildings, hotels and other service facilities that support burgeoning residential communities. As we head into 2022, demand remains at very high levels across our businesses, and we are optimistic that this will continue.

Once again, I want to express my appreciation to our dedicated employees, loyal customers and valued stockholders for their confidence and continued support.

Very truly yours,

Greg Christopher
Chairman and Chief Executive Officer

Date and Time: Thursday, May 5, 2022 8:00 A.M., Central Time	Place: 150 Schilling Boulevard Second Floor Collierville, Tennessee 38017	Record Date: March 18, 2022

We are asking you to vote on the following proposals at the Annual Meeting:

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     8

The following table provides summary information about each director nominee. The Board of Directors believes that these nominees reflect an appropriate composition to effectively oversee the performance of management in the execution of the Company’s strategy, and as such, recommends a vote “for” each of the eight nominees listed below.

A = Audit Committee

C = Compensation and Stock Option Committee

NCG = Nominating and Corporate Governance Committee

* = Chair

We ask our stockholders to approve the selection of Ernst & Young LLP (“EY”) as our independent registered public accounting firm for the fiscal year ending December 31, 2022. Below is summary information about fees paid to EY for services provided in 2021 and 2020:

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     9

We are seeking your advisory vote to approve the compensation of our named executive officers as disclosed in this proxy statement. Our executive officers are responsible for achieving long-term strategic goals, and as such, their compensation is weighted toward rewarding long-term value creation for stockholders. Beyond base salary and traditional benefits, we maintain an annual cash incentive compensation program that is driven by a pay-for-performance philosophy and based on ambitious performance targets both at the Company and business line levels. We also maintain a long-term equity incentive compensation program, the primary objective of which is to motivate and retain top talent — a particularly vital goal given the uniquely competitive industry in which we operate. Accordingly, we utilize a combination of extended time-vesting schedules and performance-based vesting criteria to encourage executives and associates alike to enjoy lengthy tenures at the Company, develop industry expertise and relationships, and drive our long-term success.

Our emphasis on a pay for performance compensation model is best illustrated in the following charts, which show that in 2021, a substantial majority of our NEOs’ overall compensation — consisting of target long-term and short-term incentive compensation combined — is performance-based or “at risk.”

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     10

PROXY STATEMENT

Eight director nominees will be elected at the Annual Meeting, each to serve until the next annual meeting (tentatively scheduled for May 4, 2023), or until the election and qualification of their successors. At the recommendation of the Nominating and Corporate Governance Committee, the Board has nominated the following persons to serve as directors for the term beginning at the Annual Meeting: Gregory L. Christopher, Elizabeth Donovan, William C. Drummond, Gary S. Gladstein, Scott J. Goldman, John B. Hansen, Terry Hermanson and Charles P. Herzog, Jr. (collectively, the “Nominees”).

Directors are elected by a plurality of the votes cast, which means that the individuals who receive the greatest number of votes cast “For” are elected as directors up to the maximum number of directors to be chosen at the Annual Meeting. Consequently, any shares not voted “For” a particular director (whether as a result of a direction to withhold or a broker non-vote) will not be counted in such director’s favor.

The Board of Directors has adopted a majority vote policy in uncontested elections. An uncontested election means any stockholders meeting called for purposes of electing any director(s) in which (i) the number of director nominees for election is equal to the number of positions on the Board of Directors to be filled through the election to be conducted at such meeting, and/or (ii) proxies are being solicited for the election of directors solely by the Company.

The election of directors solicited by this Proxy Statement is an uncontested election. In the event that a nominee for election in an uncontested election receives a greater number of votes “Withheld” for his or her election than votes “For” such election, such nominee will tender an irrevocable resignation to the Nominating and Corporate Governance Committee, which will decide whether to accept or reject the resignation and submit such recommendation for prompt consideration by the Board of Directors no later than ninety (90) days following the uncontested election.

The Nominating and Corporate Governance Committee considers, among other things, the following criteria in selecting and reviewing director nominees:

The Nominating and Corporate Governance Committee also assesses the contributions of the Company’s incumbent directors in connection with their potential re-nomination. In identifying and recommending director nominees, the Committee members take into account such factors as they determine appropriate, including recommendations made by the Board of Directors.

As reflected in its formal charter, the Nominating and Corporate Governance Committee considers the diversity of the Company’s Board and employees to be a tremendous asset. The Company is committed to maintaining a highly qualified and diverse Board, and as such, all candidates are considered regardless of their age, gender, race, color of skin, ethnic origin, political affiliation, religious preference, sexual orientation, country of origin, physical handicaps or any other category. These efforts to promote diversity are assessed annually to assure that the Board contains a balanced and effective mix of individuals capable of advancing the Company’s long-term interests.

The Nominating and Corporate Governance Committee does not consider individuals nominated by stockholders for election to the Board. The Board believes that this is an appropriate policy because the Company’s Restated Certificate of Incorporation and Amended and Restated By-laws (“Bylaws”) allow a qualifying stockholder to nominate an individual for election to the Board, said nomination of which can be brought directly before a meeting of stockholders. Procedures and deadlines for doing so are set forth in the Company’s Bylaws, the applicable provisions of which may be obtained, without charge, on the Company’s website or upon written request to the Secretary of the Company at the address set forth herein.

The presiding officer of the meeting may refuse to acknowledge the nomination of any person not made in compliance with the procedures set forth in the Bylaws. See “Stockholder Nominations for Board Membership and Other Proposals for 2022 Annual Meeting.”

CORPORATE GOVERNANCE

The Company adheres to an established set of Corporate Governance Guidelines for purposes of defining director independence, assigning responsibilities, setting high standards of professional and personal conduct, and ensuring compliance with such responsibilities and standards. Such Guidelines are periodically reviewed in light of evolving trends in corporate governance standards, regulations and related disclosure requirements, particularly as adopted by the NYSE and (with respect to the Audit Committee) the SEC.

— DIRECTOR INDEPENDENCE

In order for a director to qualify as “independent,” our Board of Directors must affirmatively determine, consistent with NYSE rules, that the director has no material relationship with the Company that would impair the director’s independence. Our Board of Directors undertook its annual review of director independence in February 2022. In applying the NYSE standards for independence, and after considering all relevant facts and circumstances, the Board of Directors has affirmatively determined that the Company’s current “independent” directors are: Elizabeth Donovan, William C. Drummond, Gennaro J. Fulvio, Gary S. Gladstein, Scott J. Goldman, John Hansen, Terry Hermanson and Charles P. Herzog, Jr. In the course of the Board of Directors’ determination regarding the independence of each non-management director, the Board considered for:

— BOARD OF DIRECTORS AND ITS COMMITTEES

The Board of Directors and its committees meet regularly throughout the year, and may also hold special meetings and act by written consent from time to time. In 2021, the Board of Directors held four regularly scheduled meetings and one special meeting. During this time, our directors attended 100% of our Board of Directors meetings and meetings of the committees on which they served. The Company’s Corporate Governance Guidelines provide that the Company’s non-management directors shall hold annually at least two formal meetings independent from management. Our Lead Independent Director presides at these executive sessions of the Board of Directors.

Three standing committees have been convened to assist the Board of Directors with various functions: the Audit Committee, the Compensation and Stock Option Committee, and the Nominating and Corporate Governance Committee. Each committee operates pursuant to a formal charter that may be obtained, free of charge, at the Company’s website at www.muellerindustries.com, or by requesting a print copy from our Corporate Secretary at the address listed herein.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     15

— BOARD LEADERSHIP STRUCTURE

The Board of Directors has currently implemented a leadership structure in which Mr. Christopher serves as both Chief Executive Officer and Chairman of the Board. The Board has determined that having Mr. Christopher serve in this dual capacity is in the best interest of stockholders at this time. The Company believes that this structure currently allows ultimate leadership and accountability to reside in a single individual, who has both extensive knowledge of the Company’s business and critical relationships with the Company’s customer base.

In order to coordinate the activities of the independent members of the Board of Directors, and to liaise between such directors and the Chairman of the Board, the Company has currently designated Mr. Hermanson to serve as Lead Independent Director. The Lead Independent Director’s responsibilities are set forth in a formal charter, which can be obtained free of charge from the Company’s website at www.muellerindustries.com, or may be requested in print by any stockholder.

— BOARD’S ROLE IN RISK OVERSIGHT

The Board of Directors is actively involved in oversight of risks that could affect the Company. These efforts can be summarized as follows:

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     16

— STANDARDS OF CONDUCT

The Board of Directors has adopted various policies, including a comprehensive set of Corporate Governance Guidelines, by which the Company is governed. These policies are designed to promote sound corporate governance and prudent stewardship of the Company, both by the Board of Directors and management.

Anti-Pledging Policy

The Corporate Governance Guidelines include amendments adopted in February 2020 that prohibit the future pledging of the Company’s common stock as security under any obligation by our directors and executive officers.

Insider Trading and Anti-Hedging Policy

The Company maintains a policy which mandates compliance with insider trading laws and institutes safeguards to mitigate the risk of insider trading. Further, the Corporate Governance Guidelines prohibit any director, officer or employee of the Company from engaging in short sales, transactions in derivative securities (including put and call options), or other forms of hedging and monetization transactions, such as zero-cost collars, equity swaps, exchange funds and forward sale contracts, that allow the holder to limit or eliminate the risk of a decrease in the value of the Company’s securities.

Clawback Policy

Under the Corporate Governance Guidelines, if the Company is required to restate its financial results due to material noncompliance with financial reporting requirements under the securities laws as a result of an executive’s (i.e., a President or Vice President level officer’s) willful, knowing or intentional misconduct or gross negligence (as determined by the Compensation and Stock Option Committee), the Company may take action to recoup from the executive all or any portion of an incentive award received by the executive, the amount of which had been determined in whole or in part upon specific performance targets relating to the restated financial results. In such an event, the Company shall be entitled to recoup up to the amount, if any, by which the incentive award actually received by the executive exceeded the payment that would have been received based on the restated financial results, as determined by the Compensation and Stock Option Committee. The Company’s right of recoupment pursuant to this policy applies to incentive awards received during the three-year period preceding the date on which the Company is required to prepare the restatement, based on the determination of the Company’s independent registered public accounting firm.

Code of Business Conduct and Ethics

The Company has adopted a Code of Business Conduct and Ethics, which is designed to help officers, directors and employees resolve ethical issues in an increasingly complex business environment. The Code of Business Conduct and Ethics is applicable to all of the Company’s officers, directors and employees, including the Company’s principal executive officer, principal financial officer, principal accounting officer or controller and other persons performing similar functions. The Code of Business Conduct and Ethics covers topics, including but not limited to, conflicts of interest, confidentiality of information and compliance with laws and regulations.

Director Responsibilities

It is the duty of the Board of Directors to serve as prudent fiduciaries for stockholders and to oversee the management of the Company’s business. Accordingly, the Corporate Governance Guidelines include specifications for director qualification and responsibility, attendance, access to officers and employees, compensation, orientation, continuing education and self-evaluation.

The Company’s policy is that all members of the Board of Directors attend annual meetings of stockholders, except where the failure to attend is due to unavoidable circumstances or conflicts discussed in advance with the Chairman of the Board. Because of travel restrictions and safety concerns related to the COVID-19 pandemic, the Chairman was present but excused all non-management members of the Board of Directors from attending the 2021 annual meeting of stockholders in person.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     17

— COMMUNICATION WITH THE BOARD OF DIRECTORS

Any stockholder or interested party who wishes to communicate with the Board of Directors, or specific individual directors, including the non-management directors as a group, may do so by directing a written request addressed to such directors or director in care of the Chairman of the Nominating and Corporate Governance Committee, Mueller Industries, Inc., 150 Schilling Boulevard, Suite 100, Collierville, Tennessee 38017. Communication(s) directed to the Chairman will be relayed to him, except to the extent that it is deemed unnecessary or inappropriate to do so pursuant to the procedures established by a majority of the independent directors. Communications directed to non-management directors will be relayed to the intended director except to the extent that doing so would be contrary to the instructions of the non-management directors. Any communication so withheld will nevertheless be made available to any non-management director who wishes to review it.

— RELATED PARTY TRANSACTIONS

Related party transactions may present potential or actual conflicts of interest, and create the appearance that Company decisions are based on considerations other than the best interests of the Company and its stockholders. Management carefully reviews all proposed related party transactions (if any), other than routine banking transactions, to determine if the transaction is on terms comparable to those that could be obtained in an arms-length transaction with an unrelated third party. Management reports to the Audit Committee, and then to the Board of Directors on all proposed material related party transactions. Upon the presentation of a proposed related party transaction to the Audit Committee or the Board of Directors, the related party is excused from participation in discussion and voting on the matter.

The Company assesses and manages environmental, social and governance (“ESG”) considerations that may be material to the long-term sustainability of our business. In February 2021, the Nominating and Corporate Governance Committee’s charter was formally amended to include the management of ESG risk within the Committee’s jurisdiction. Pursuant to its charter, the Nominating and Corporate Governance Committee is responsible for reviewing and discussing with management the Company’s implementation of procedures for identifying, assessing, monitoring, managing and reporting on the ESG and sustainability risks and opportunities related to the Company’s business. Among other matters, we focus on such issues as workplace health and safety, environmental stewardship, business ethics and compliance, supply chain management and the development of human capital. We also focus outwardly on the communities in which we operate, including through a foundation that makes charitable contributions to various causes and organizations. ESG-related risks and opportunities are integral to our strategic decision-making. Such matters are addressed by senior management and subject to the oversight of the Nominating and Corporate Governance Committee and the full Board of Directors. The Company is also prioritizing the enhanced reporting and disclosure of the ESG-related risks and opportunities relating to its business and associated metrics, and in 2021, published its first sustainability report. The Company recently published its 2022 sustainability report, which features updates and additional disclosure. The report is available on the Company’s website.

— 2021 NON-EMPLOYEE DIRECTOR COMPENSATION

The table below summarizes the total compensation we paid to our non-employee directors for the fiscal year ended December 25, 2021.

— STOCK OWNERSHIP POLICY FOR DIRECTORS

To further align the Company’s goal of aligning directors’ economic interests with those of stockholders, the Company has adopted stock ownership guidelines for its non-employee directors recommending that they hold equity interests of the Company (including vested and unvested interests, provided that with respect to options, only vested options that are exercisable within 60 days of the applicable measurement date will be counted) with a value equal to three times the annual cash director fee payable to each such director. All directors are expected to comply with the stock ownership guidelines within five years of being elected to the Board of Directors, and current directors should comply as soon as practicable. Director compliance with the stock ownership guidelines is monitored on an ongoing basis by the Company’s General Counsel.

PROPOSAL 2   APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has reappointed Ernst & Young LLP (“EY”) to audit and certify the Company’s financial statements for the fiscal year ended December 25, 2021, subject to ratification by the Company’s stockholders, which requires the affirmative vote of a majority of the outstanding shares of the Company present in person or by proxy at the Annual Meeting. If the appointment of EY is not so ratified, the Audit Committee will reconsider its action and will appoint auditors for the 2022 fiscal year without further stockholder action. Notwithstanding, the Audit Committee may at any time in the future in its discretion reconsider the appointment without submitting the matter to a vote of stockholders. Representatives of EY are expected to attend the Annual Meeting to answer questions and make a statement if they so choose.

Fees for EY’s audit and other services for each of the two fiscal years ended December 25, 2021 and December 26, 2020 are set forth below:

The Audit Committee’s policy is to pre-approve all audit and non-audit services provided by the independent auditors. Pre-approval is generally provided for up to one year, and any such pre-approval is detailed as to the particular service or category of services. The Audit Committee has delegated pre-approval authority to its Chairman when expedition of services is necessary. The independent auditors and management are required periodically to report to the full Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. All of the services provided by the independent auditors during fiscal years 2021 and 2020, respectively, under the categories Audit Fees, Audit-Related Fees, Tax Fees and All Other Fees described above were pre-approved.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE THEIR SHARES FOR THE APPROVAL OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     21

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report on Form 10-K with management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under Public Company Accounting Oversight Board’s (PCAOB) Auditing Standard No. 1301. In addition, the Audit Committee discussed with the independent auditors the auditors’ independence from management and the Company, including the matters in the written disclosures required by Public Company Accounting Oversight Board’s Rule 3526, and considered the compatibility of non-audit services provided by the independent auditors with the auditor’s independence.

The Audit Committee discussed with the Company’s internal and independent auditors the overall scope and plans for their respective audits. The Audit Committee meets with the internal and independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board of Directors has approved) that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 25, 2021 for filing with the SEC. The Audit Committee and the Board has re-appointed, subject to stockholder approval, Ernst & Young LLP, independent auditors, to audit the consolidated financial statements of the Company for the fiscal year ending December 31, 2022.

The Audit Committee is governed by a formal charter which can be accessed from the Company’s website at www.muellerindustries. com, or may be requested in print by any stockholder. The members of the Audit Committee are considered independent because they satisfy the independence requirements for Board members prescribed by the NYSE listing standards and Rule 10A-3 of the Exchange Act.

PROPOSAL 3   ADVISORY VOTE ON APPROVAL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS

In accordance with Section 14A of the Exchange Act, stockholders are being asked to vote on an advisory, non-binding basis, on the compensation of the Company’s named executive officers. Specifically, the following resolution will be submitted for a stockholder vote at the Annual Meeting, the approval of which will require the affirmative vote of a majority of the outstanding shares of the Company present in person or by proxy at the Annual Meeting and entitled to vote thereon:

“RESOLVED, that the stockholders of the Company approve, on an advisory basis, the compensation of the Company’s named executive officers listed in the 2021 Summary Compensation Table included in the proxy statement for the 2022 Annual Meeting, as such compensation is disclosed pursuant to Item 402 of Regulation S-K in this proxy statement under the section titled “Compensation Discussion and Analysis,” as well as the compensation tables and other narrative executive compensation disclosures thereafter.”

Although the stockholder vote is not binding on either the Board of Directors or the Company, the views of stockholders on these matters are valued and will be taken into account in addressing future compensation policies and decisions.

The Company’s Compensation and Stock Option Committee is comprised of knowledgeable and experienced independent directors, who are committed to regular review and effective oversight of our compensation programs. The Company’s executive compensation program is grounded in a pay for performance philosophy, and accordingly, has been designed to motivate the Company’s key employees to achieve the Company’s strategic and financial goals, and to support the creation of long-term value for stockholders. Moreover, given the particularly competitive markets in which we operate and the nature of our business, a principal goal underlying the Company’s long-term incentive compensation program specifically is the long-term retention and motivation of critical executives and business leaders. The Company’s success depends upon their leadership, judgment and experience, and as such, our compensation program is designed to promote their enduring commitment to the Company. We encourage stockholders to read the Executive Compensation section of this proxy statement, including the Compensation Discussion and Analysis (CD&A) and compensation tables, for a more detailed discussion of the Company’s compensation programs and policies, and how they are appropriate and effective in promoting growth, creating value, and retaining key members of our team.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE THEIR SHARES FOR THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

COMPENSATION DISCUSSION AND ANALYSIS   TABLE OF CONTENTS

— EXECUTIVE SUMMARY

This Compensation Discussion and Analysis (“CD&A”) provides an overview of how our named executive officers were compensated in 2021, as well as how this compensation furthers our established compensation philosophy and objectives.

Our Named Executive Officers

The Company’s NEOs for fiscal year 2021 were:

Our Compensation Philosophy and Guiding Principles

We believe in a pay for performance philosophy, such that a material portion of a named executive officer’s compensation is dependent upon both the short-term and long-term strategic and financial performance of the Company, considered in light of general economic and specific Company, industry, and competitive conditions. For 2021, we continued to reward our NEOs in a manner consistent with this philosophy by setting annual incentive targets based on the Company’s achievement of certain levels of operating income. While also rooted in a pay for performance philosophy, our long-term equity incentive compensation focused primarily on promoting the retention of key executives and business leaders in our industry, where the competition for leadership talent is a foremost concern. Accordingly, we continued to grant equity awards, such that any long-term compensation opportunity will be directly tied to stock performance, and will only be received by key executives and business leaders who remain with and make long-term commitments to the Company’s success. The Compensation and Stock Option Committee (hereinafter referred to as “the Committee” for purposes of this CD&A section) evaluates, on an annual basis, the overall structure and design of our program, and believes it has and continues to reflect the best balance of the Company’s priorities.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     24

Our Compensation Practices At a Glance

Our pay and equity programs are designed to align executives’ interests with those of our stockholders, and to motivate and retain critical leaders. Below is a snapshot of our compensation practices:

WHAT WE DO			WHAT WE DON’T DO
	We maintain a fully independent Compensation and Stock Option Committee.			We do not provide for single trigger severance upon a change in control.
	A higher percentage of our executives’ compensation is variable than fixed.			We do not permit gross-up payments to cover excise taxes.
	We utilize varying performance metrics under our short-term and long-term incentive plans.			We do not permit the pledging or hedging of our common stock.
	Our annual incentive program is based on earnings performance and capped for maximum payouts.			We do not support compensation programs or policies that reward material or excessive risk taking.
	Our equity awards include extended vesting schedules and performance-based criteria.			We do not maintain any supplemental executive retirement plans.
	We have a clawback policy applicable to all senior employees, including all President and Vice President level personnel.

2021 Say-on-Pay Vote and Stockholder Engagement

At our 2021 Annual Meeting, we held our annual non-binding stockholder advisory vote on executive compensation. Approximately 94% of our shares voted (excluding abstentions and broker non-votes) were in favor of the compensation of our named executive officers as disclosed in the proxy statement for the 2021 Annual Meeting.

We were gratified by the level of stockholder support received in 2021 for our non-binding stockholder advisory vote on executive compensation, as it represented a significant improvement over the prior two years, and signified a recognition of our efforts to engage with stockholders on executive compensation matters. In 2021, we sought to further improve our pay-for-performance alignment by making 100% of the total equity awards granted to our NEOs performance-based.

As in prior years, the Committee will consider the outcome of this year’s stockholder advisory vote on executive compensation as it makes future compensation decisions.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     25

— DETERMINATION OF EXECUTIVE COMPENSATION

Guided by the philosophy and design outlined above, the Committee determines the compensation of our Chief Executive Officer. In turn, our Chief Executive Officer makes recommendations to the Committee regarding all components of our other NEOs’ compensation, including base salary, annual cash incentive compensation, and long-term equity incentive compensation. The Committee considers and acts upon those recommendations in setting the compensation of our other NEOs.

In determining compensation, we generally do not rely upon hierarchical or seniority-based levels or guidelines, nor did the Committee formally benchmark executive compensation (or any component thereof) against any particular peer group. Instead, we utilize a more flexible approach that allows us to adapt components and levels of compensation to motivate and reward individual executives within the context of our broader strategic and financial goals. This requires that we consider subjective factors including, but not limited to the following:

In making compensation decisions, the Committee relies on the members’ general knowledge of our industry, supplemented by advice from our Chief Executive Officer based on his knowledge of our industry and the markets in which we participate. From time to time, we conduct informal analyses of compensation practices and our Compensation and Stock Option Committee may review broad-based third-party surveys to obtain a general understanding of current compensation practices.

The Committee has chosen incentive operating income targets as the metric to measure performance for each named executive officer. The compensation of Messrs. Christopher, Martin and Miritello is based upon their oversight of and responsibility for the entire Company. Accordingly, their compensation levels are reflective of the scope and breadth of their management responsibility, and the performance of the Company on a consolidated basis. A portion of Mr. Sigloch’s compensation is based upon the performance of specific business lines within his purview. Notwithstanding the foregoing, a portion of his compensation is still based upon consolidated Company performance to discourage parochialism and to align his interests with those of our stockholders.

— ELEMENTS OF COMPENSATION

As outlined below, our compensation program for our NEOs is comprised of three primary elements: (i) base salary and traditional benefits, (ii) annual incentive compensation, and (iii) long-term equity incentive compensation. Each element plays an integral role in our overall compensation strategy. Moreover, the Committee has approved certain executive perquisites and post-employment change-in-control compensation to our NEOs for purposes of motivating them and retaining their services.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     26

Pay-for-Performance and At-Risk Compensation

Base Salary and Traditional Benefits

Base salaries paid to our NEOs are set forth in the “Summary Compensation Table for 2021.” Base salary adjustments are determined by making reasoned subjective determinations about current economic conditions such as general wage inflation as well as the executive’s qualifications, experience, responsibilities, and past performance. In addition to base salaries, we provide traditional benefits such as group health, disability, and life insurance benefits, as well as matching contributions to our 401(k) plan.

Annual Incentive Compensation

Each of our NEOs received annual incentive compensation for 2021, based upon the actual performance of the Company and, for Mr. Sigloch, the performance of the business lines he oversees, relative to the performance targets (as described below), which were originally established by the Committee on February 1, 2021, and then supplemented on July 29, 2021. The table below shows the target annual incentive award for each of our NEOs.

For 2021, the amount of incentive compensation payable to each of our named executive officers was calculated as follows:

INCENTIVE GRADE LEVEL FACTOR

Set forth below are the incentive grade level factors for each of our NEOs:

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     27

PERFORMANCE FACTOR

Set forth below are the corresponding payout percentages tied to various levels of achievement above or below pre-approved primary operating income performance targets. To promote alignment between pay and performance, incentive compensation amounts are not paid to NEOs when the achievement level of the operating income performance target is less than 80%.

Based on their incentive grade level factors, our NEOs are entitled to an additional payout percentage of 10% for each additional percentage of achievement between 111% and 115% of the target, thereby resulting in a maximum payout percentage of 200%. As explained more fully below (see footnote 2 in the following table), given the Company’s exceptionally strong performance in 2021, secondary operating income targets were set and approved by the Committee on July 29, 2021, and our NEOs were further entitled to earn additional payouts based on performance as compared with those secondary targets.

The performance factor applicable to each of the NEOs was determined based on the achievement level of the consolidated Company incentive operating income target, as shown in the following table:

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     28

2021 NEO ANNUAL INCENTIVE CALCULATIONS

As a result of 2021 performance, the annual incentive payments for the NEOs were calculated as follows:

Long-Term Equity Incentive Compensation Program

OVERVIEW

Our long-term equity-based incentive compensation program serves three goals:

The Committee has made the retention of executives and key employees a particular focus of the long-term equity incentive compensation program in recent years.

The Committee has decided that the best way to meet the objectives of our long-term incentive program is to award a combination of performance-based restricted stock and time-based restricted stock. In 2021, to further emphasize the alignment of pay and performance, the Committee chose to award only performance-based restricted stock to our NEOs, which, provided performance criteria are met, will cliff vest after a period of three years.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     29

NEO LONG-TERM EQUITY MIX

The Committee believes that the extended and cliff vesting schedules, and performance criteria described below will motivate our NEOs and key employees to remain with the Company and make long-term contributions to stockholder value generation.

VESTING SCHEDULE FOR PERFORMANCE-BASED RESTRICTED STOCK

To foster executive retention, 100% of the 2021 awards given to our NEOs, all of which are performance-based, will cliff vest after a period of three years. Thus, no portion of the equity awards granted to our NEOs (or any of our employees) will vest in less than three years. The Committee elected to use a long-term vesting schedule to promote executive retention in our competitive industry and to incentivize performance. However, given the importance of long-term equity incentive awards in our compensation program, the Committee provided for accelerated vesting in the event of death, disability or a change in control (as explained in more detail in the “2021 Grant of Plan Based Awards Table”). The Committee believes that accelerated vesting would be appropriate in those circumstances to encourage our executives to focus on the potential benefits of a change in control transaction for our stockholders without harboring concerns for their financial security.

PERFORMANCE CRITERIA FOR PERFORMANCE-BASED RESTRICTED STOCK

Of the long-term equity awards granted to our NEOs in 2021, 100% are performance-based, and vesting is contingent upon the Company’s performance on two metrics: (i) adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), and (ii) average return on invested capital (ROIC). As discussed in last year’s proxy, the Company adopted these operational metrics in 2020 in response to stockholder outreach regarding the appropriateness of the metrics historically used by the Company. Using these two metrics ensures that performance-based awards to these NEOs will only vest based upon the achievement of specified growth targets over a three-year performance period, which for the 2021 grants, was December 27, 2020 to December 31, 2023. For this purpose, the adjusted EBITDA metric means the average adjusted EBITDA achieved by the Company during each of the three fiscal years during the performance period, as compared with an adjusted EBITDA target of $216.24 million. The average ROIC metric means the average ROIC achieved by the Company during each of the three fiscal years during the performance period, as compared with an average ROIC target of 11.0%. For purposes of the average ROIC metric, ROIC means, in respect of a given fiscal year, the quotient obtained by dividing the Company’s after-tax operating income for such fiscal year by average invested capital in respect of such fiscal year (with invested capital being the average of beginning and ending long-term debt and equity in respect of such fiscal year).

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     30

The degree to which the performance-based equity awards granted to our NEOs vest is contingent upon the Company’s actual performance as compared with the adjusted EBITDA and average ROIC targets, each weighted on a 50%-50% basis. The tables below illustrate the applicable achievement levels and corresponding vesting percentages for each metric. In both tables, the vesting percentages reflect the 50%-50% weighting of the two metrics. As for each metric, if the achievement percentage is less than 80%, the vesting percentage is 0%. Moreover, if the achievement percentage is between the specified levels, the vesting percentage is determined by linear interpolation.

To be clear, the growth targets established for our performance-based equity grants are just one of a number of different, yet complementary performance metrics utilized by the Company in its efforts to design an overall compensation program that is appropriately balanced and furthers its underlying aims. For example, the Company’s performance-based compensation program also incorporates the ambitious short and long-term operating targets that underlie the Company’s annual cash incentive compensation program and long-term aspirations for strategic growth.

The Company has traditionally maintained, and will continue to maintain lofty expectations and goals with respect to stockholder value creation. Nevertheless, given the primary retention aim of the long-term equity incentive compensation program, the Committee has concluded that the performance-based criterion for the equity awards granted to our NEOs are appropriate in the context of our well-balanced overall executive compensation program.

TIMING OF LONG-TERM EQUITY AWARD GRANTS

Long-term equity incentive awards to our Chief Executive Officer and other NEOs are traditionally granted annually, typically following the release of the Company’s second quarter and six-month operating results, and are based on the determinations of the Committee. Our Chief Executive Officer makes recommendations to the Committee regarding awards for other NEOs and members of the management team. In 2021, the NEOs received their annual grants in August.

In granting long-term equity awards to our NEOs, the Committee applied no set formula for allocating awards, and instead made reasoned, subjective determinations based upon their performance, the importance of retaining their services, and their role in helping us achieve our long-term goals. In 2021, we granted shares of restricted stock to our NEOs covering an aggregate of 127,000 shares.

Perquisites

We offer perquisites to our NEOs, which we view as an added element of our executive compensation program designed not only to attract, retain and reward our NEOs, but also to facilitate the performance of their duties on behalf of the Company. The perquisites we provided to our NEOs in fiscal year 2021 are set forth in the “Summary Compensation Table for 2021”, and included, among others, estate and tax planning, personal use of our Company airplane, and reimbursement of the income tax liabilities associated with certain perquisites. Estate and tax planning is provided to certain NEOs to complement our various compensation elements for the purpose of ensuring the NEOs understand the complexity of the long-term equity incentives and are thereby able to maximize the value of such benefits. We maintain a Company-owned airplane primarily to provide efficient transportation for executives, employees and customers to our geographically dispersed operations. From time to time, when our plane is not being used for business purposes, we allow certain NEOs to use the plane for personal travel. We have also provided executive physicals as a risk management tool and to ensure our NEOs are mindful of their personal health. Certain club memberships are provided, and serve the primary aim of facilitating networking with business clients.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     31

In connection with its continued appraisal of our compensation program, management, with oversight from the Committee, reviews our compensation policies and practices, and the overall compensation program with respect to our risk management practices and any potential risk-taking incentives. This assessment includes a review of the primary elements of our compensation in light of potential risks:

COMPENSATION PROGRAM RISK CONSIDERATIONS

As previously detailed (see page 17), the Company has adopted a series of policies, including bans on pledging and hedging, and a clawback policy, to further mitigate risk taking behaviors. Beyond our Company clawback policy, which applies to all President and Vice President-level executives, our Chief Executive Officer and Chief Financial Officer are subject to clawback provisions under the Sarbanes Oxley Act of 2002. For these reasons, we believe that our compensation policies and practices are not likely to have a material adverse effect on the Company.

Tax Considerations

Section 162(m) of the Internal Revenue Code (the “Code”) generally disallows a tax deduction to public companies for compensation in excess of $1,000,000 paid to certain executive officers, subject historically to an exception for qualifying “performance-based compensation.” The Tax Cuts and Jobs Act, enacted on December 22, 2017, substantially modified Section 162(m) of the Code and, among other things, eliminated the performance-based exception to the $1,000,000 deduction limit and expanded the scope of the executive officers who are subject to Section 162(m) of the Code.

To maintain flexibility in compensating executive officers in a manner designed to promote varying corporate goals in the best interest of the company, we consider the impact of Section 162(m) of the Code when determining executive compensation, but we do not limit our actions with respect to executive compensation to preserve deductibility under Section 162(m) of the Code if we determine that doing so is in the best interests of the Company and its stockholders.

COMPENSATION AND STOCK OPTION COMMITTEE REPORT

The Compensation and Stock Option Committee has reviewed and discussed with the Company’s management the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K. Based on such review and discussions, the Compensation and Stock Option Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

Gennaro J. Fulvio
Gary S. Gladstein

During fiscal year 2021, Gary S. Gladstein, Scott J. Goldman and Charles P. Herzog, Jr. served on the Compensation and Stock Option Committee. No member of the Compensation and Stock Option Committee was, during fiscal year 2021, an officer or employee of the Company or was formerly an officer of the Company. In addition, no member of the Compensation and Stock Option Committee, during fiscal year 2021, had any relationship requiring disclosure by the Company as a related party transaction under Item 404 of Regulation S-K. No executive officer of the Company served on any board of directors or compensation committee of any other company for which any of the Company’s directors served as an executive officer at any time during fiscal year 2021.

Pay Ratio

In 2021, the total compensation of Mr. Christopher, our Chief Executive Officer, was $10,841,767 as reported in the “Summary Compensation Table for 2021.” Based on the methodology described below, we determined that the median employee in terms of total 2021 compensation of all of our employees (other than Mr. Christopher) received an estimated $39,390 in total compensation for 2021. Therefore, the estimated ratio of 2021 total compensation of Mr. Christopher to the median employee was 275:1.

In general, we offer employees base salary, company retirement plan contributions, the opportunity to receive incentive awards for performance, and other benefits. In accordance with SEC rules, the median employee compensation provided above reflects company retirement plan contributions, incentive awards for 2021 performance and other benefits, but does not reflect benefits relating to group life or health plans generally available to all salaried employees.

To determine median employee compensation, we took the following steps:

The following table sets forth summary information regarding all grants of plan-based awards made to our named executive officers for the fiscal year ended December 25, 2021.

Narrative Disclosure to Summary Compensation Table and Grant of Plan Based Awards Table

Employment Agreement with Mr. Christopher

On March 15, 2018, we entered into an indefinite term employment agreement (the “Employment Agreement”) with Mr. Christopher, pursuant to which he will continue to serve as the Company’s Chief Executive Officer, reporting directly to the Board. The Employment Agreement replaced Mr. Christopher’s prior employment agreement and, in so doing, eliminated the “single-trigger” severance to which Mr. Christopher would have been entitled upon the occurrence of a change in control of the Company.

The Employment Agreement provides that Mr. Christopher will receive a base salary of not less than $1,100,000 per year and will be eligible to receive an annual bonus award. For each fiscal year, Mr. Christopher’s target annual bonus will be 125% of his base salary upon achievement of target performance levels, and he will be eligible for a maximum annual bonus of 250% of base salary when performance equals or exceeds 125% of the applicable performance objectives. The actual annual bonus payable to Mr. Christopher will be based upon the actual level of achievement of annual Company and individual performance objectives for the applicable year, as determined by the Committee. In addition, during the term of Mr. Christopher’s employment, the Company will maintain a term life insurance policy for him with a face value of at least $5 million, and Mr. Christopher will have the right to name the beneficiary of such term life insurance policy.

In the event that Mr. Christopher’s employment is terminated for any reason (other than by the Company for “cause” (as defined in the Employment Agreement)), he will, subject to his execution of a general release in favor of the Company and his continued compliance with certain restrictive covenants (the “Conditions”), be entitled to receive the following: (i) any accrued but unpaid compensation and benefits; (ii) any unpaid annual bonus with respect to the previously completed fiscal year; (iii) subject to achievement of the applicable performance objectives for the fiscal year in which the termination occurs, payment of a prorated annual bonus for such fiscal year; and (iv) continued medical, dental and hospitalization coverage (or payment in lieu of coverage if coverage is not permitted by applicable law or the terms of the applicable plan) for Mr. Christopher, his spouse and covered dependents until the latest of Mr. Christopher’s 70^th birthday, his spouse’s 70^th birthday, and the 3^rd anniversary of such termination.

MUELLER INDUSTRIES  •  2022 PROXY STATEMENT     36

Additionally, if Mr. Christopher’s employment is terminated by the Company without “cause” or by Mr. Christopher for “good reason” (as defined in the Employment Agreement), and there has not been a “change in control” (as defined in the Employment Agreement) in the past 24 months, Mr. Christopher will, subject to the Conditions, be entitled to (i) continued payment of his base salary for 36 months; and (ii) an amount equal to 3 times Mr. Christopher’s target annual bonus in respect of the fiscal year in which such termination occurs (or prior fiscal year, if greater), such amount to be paid in equal installments over the 3-year period following such termination at the same time such amounts would otherwise have been paid had no termination occurred. If Mr. Christopher’s employment is terminated by the Company without “cause” or by Mr. Christopher for “good reason” within 24 months of a “change in control,” Mr. Christopher will, subject to the Conditions, be entitled to (i) payment of his base salary for 36 months in a lump sum on the first regularly-scheduled payroll date following the 60^th day following such termination; and (ii) an amount equal to 3 times Mr. Christopher’s target annual bonus in respect of the fiscal year in which such termination occurs (or prior fiscal year, if greater), paid in a lump sum on the first regularly-scheduled payroll date following the 60^th day following such termination. The Employment Agreement does not provide for any “single-trigger” severance payments or benefits.

The Employment Agreement does not provide any gross-up or tax assistance on the severance benefits. Instead, the Employment Agreement contains a “modified cutback” provision, which would act to reduce the benefits payable to Mr. Christopher to the extent necessary to avoid a “golden parachute excise tax,” but only if such reduction would result in Mr. Christopher retaining a larger after-tax amount.

Mr. Christopher is subject to certain restrictive covenants during the term of his employment and thereafter, including customary non-compete restrictions that apply for one year post-termination and customary non-solicitation restrictions with respect to current and prospective employees that apply for one year post-termination. In addition, during the term of his employment and for one year thereafter, Mr. Christopher is prohibited from contacting any customer or prospective customer of the Company, or any representative of the same, for the purpose of providing any service or product competitive with any service or product sold or provided by the Company.

Change in Control Agreements with Messrs. Martin, Sigloch and Miritello

On July 26, 2016, the Company entered into change in control agreements with certain key members of the management team, including Messrs. Martin and Sigloch. The Company entered into a substantially similar change in control agreement with Mr. Miritello on January 3, 2017. Pursuant to those agreements, if, upon or within two years following a “change in control”, the executive’s employment is terminated by the Company without “cause” (other than on account of death or Disability), or by the executive for “good reason”, subject to execution of a general release of claims, the executive will be entitled to: (i) an amount equal to two times the executive’s base salary (as in effect immediately prior to the change in control or, if greater, the date of such termination); and (ii) an amount equal to two times the average annual bonus paid to the executive (including, for this purpose only, any amounts deferred) in respect of the three calendar years immediately preceding the calendar year in which the change in control occurs (or the three calendar years immediately preceding the calendar year of such termination, if greater). On February 22, 2022, the Company entered into amended change in control agreements with Messrs. Martin and Miritello, pursuant to which, if, upon or within three years following a “change in control”, the executive’s employment is terminated by the Company without “cause” (other than on account of death or Disability), or by the executive for “good reason”, subject to execution of a general release of claims, each executive is entitled to three times the executive’s base salary and three times the executive’s average annual bonus, as outlined in the foregoing. The terms “change in control” and “cause” are defined in the 2014 Incentive Plan and the term “good reason” is defined in each executive’s change in control agreement, as amended. The agreements also provide that for two years following termination under the circumstances described above, each of Messrs. Martin, Sigloch and Miritello will receive (subject to the executive’s election of COBRA continuation coverage under the Company’s group health plan) continued coverage under the Company’s group health plan at the Company’s cost (or at the direction of the Company, reimbursement for COBRA premiums) for two years following such termination.

Further, the amended agreements with Messrs. Martin and Miritello provide that if either executive is terminated without “cause,” notwithstanding the non-occurrence of a “change in control,” he is entitled to (i) an amount equal to two times the executive’s base salary (as in effect immediately prior to the date of such termination); and (ii) an amount equal to two times the average annual bonus paid to the executive (including, for this purpose only, any amounts deferred) in respect of the three calendar years immediately preceding the calendar year in which such termination occurs.

2019 and 2014 Incentive Plans

In 2021, we maintained the 2019 Incentive Plan and 2014 Incentive Plan (together, the “Plans”), which were approved by our stockholders at our Annual Meetings held in May 2019 and May 2014 respectively. The Committee administers the Plans and is authorized to, among other things, designate participants, grant awards, including cash-based awards that historically were intended to qualify as performance-based compensation for purposes of Section 162(m) of the Internal Revenue Code, determine the number of shares of Common Stock to be covered by awards and determine the terms and conditions of any awards, and construe and interpret the Plans and award agreements issued pursuant thereto. The 2014 Incentive Plan reserved 1,500,000 shares of our Common Stock for issuance, subject to adjustment in the event of any change in the outstanding Common Stock or the capital structure of the Company or any other similar corporate transaction or event. The 2019 Plan reserved 2,000,000 shares of our Common Stock for issuance, subject to adjustments under similar circumstances.

ADDITIONAL MATTERS

—  VOTING SECURITIES

At the close of business on the Record Date, there were 57,234,851 shares of Common Stock outstanding, which are the only shares entitled to be voted at the Annual Meeting. Each share of Common Stock is entitled to one vote. Only stockholders of record at the close of business on the Record Date will be entitled to notice of, and to vote at, the Annual Meeting. The Bylaws do not provide for cumulative voting for the election of directors.

On March 9, 2017, the Company paid a special dividend (the “Special Dividend”) consisting of $3.00 in cash and $5.00 in principal amount of the Company’s 6% Subordinated Debentures due 2027 (the “Debentures”, which were fully redeemed by the Company on April 15, 2021) for each share of Common Stock outstanding as of the close of business on February 28, 2017. In connection with the Special Dividend, in accordance with the Company’s outstanding stock option plans and agreements, the Company adjusted the shares subject to and the per share exercise price with respect to outstanding options. This adjustment resulted in an increase in the number of shares subject to each outstanding option and an adjustment to the option purchase price designed to maintain the option holders’ intrinsic value following issuance of the Special Dividend. References in this Proxy Statement to beneficial stock ownership or outstanding options for periods following March 9, 2017 reflect the equitable adjustment made to options outstanding on February 28, 2017.

—  STOCKHOLDER NOMINATIONS FOR BOARD MEMBERSHIP AND OTHER PROPOSALS FOR THE 2023 ANNUAL MEETING

It is anticipated that the next Annual Meeting after the one scheduled for May 5, 2022 will be held on or about May 4, 2023. The Company’s Bylaws require that, for nominations of directors or other business to be properly brought before an Annual Meeting, written notice of such nomination or proposal for other business must be furnished to the Company. Such notice must contain certain information concerning the nominating or proposing stockholder and information concerning the nominee and must be furnished by the stockholder (who must be entitled to vote at the meeting) to the Secretary of the Company, in the case of the Annual Meeting to be held in 2023, no earlier than December 7, 2022 and no later than January 6, 2023. To comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by SEC Rule 14a-19 under the Exchange Act no later than March 6, 2023. A copy of the applicable provisions of the Bylaws may be obtained by any stockholder, without charge, upon written request to the Secretary of the Company at the address set forth below.

In addition to the foregoing, and in accordance with the rules of the SEC, in order for a stockholder proposal, relating to a proper subject, to be considered for inclusion in the Company’s proxy statement and form of proxy relating to the Annual Meeting to be held in 2023, such proposal must be received by the Secretary of the Company by December 1, 2022 in the form required under and subject to the other requirements of the applicable rules of the SEC. If the date of the Annual Meeting to be held in 2023 is changed to a date more than 30 days earlier or later than May 4, 2023, the Company will inform the stockholders in a timely fashion of such change and the date by which proposals of stockholders must be received for inclusion in the proxy materials. Any such proposal should be submitted by certified mail, return receipt requested, or other means, including electronic means, that allow the stockholder to prove the date of delivery.

If a stockholder intends to present a proposal at the 2023 Annual Meeting without any discussion of the proposal in our proxy statement, and the stockholder does not notify us of such proposal on or before February 14, 2023 as required by SEC Rule 14a-4(c)(1), then proxies received by us for the 2023 Annual Meeting will be voted by the persons named as such proxies in their discretion with respect to such proposal.
