  4. ELECTION OF DIRECTORS

    ELECTION OF DIRECTORS Eight director nominees will be elected at the Annual Meeting, each to serve until the next annual meeting (tentatively scheduled for May 7, 2026), or until the election and qualification of their successors. At the recommendation of the Nominating and 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 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.

  5. — SELECTING NOMINEES TO THE BOARD

    — SELECTING NOMINEES TO THE BOARD The Nominating and Governance Committee considers, among other things, the following criteria in selecting and reviewing director nominees:

  6. — SELECTING NOMINEES TO THE BOARD

    | • | personal and professional integrity, and the highest ethical standards; | | • | skills, business experience and industry knowledge useful to the oversight of the Company based on the perceived needs of the Company and the Board at any given time; | | • | the ability and willingness to devote the required amount of time to the Company’s affairs, including attendance at Board and committee meetings; | | • | the interest, capacity and willingness to serve the long-term interests of the Company; and | | • | the lack of any personal or professional relationships that would adversely affect a candidate’s ability to serve the best interests of the Company and its stockholders. |

  7. — SELECTING NOMINEES TO THE BOARD

    The Nominating and 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 consider such factors as they determine appropriate, including recommendations made by the Board of Directors. As reflected in its formal charter, the Nominating and 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, disability or any other category. Through Charter amendments enacted in February 2023, the Nominating and Governance Committee reaffirmed its commitment to including, in each search, qualified candidates who reflect diverse backgrounds, including diversity of gender and race. Moreover, the Committee will consider all candidates irrespective of whether their backgrounds includes work in the corporate, academic, government or non-profit sectors. 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 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

  25. — DETERMINATION OF EXECUTIVE COMPENSATION

    — DETERMINATION OF EXECUTIVE COMPENSATION Guided by the philosophy and design outlined above, the Committee determines the compensation of our CEO. In turn, our CEO 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:

  26. — ELEMENTS OF COMPENSATION

    | Element of Compensation | Purpose/Description | Form/Timing of Payment | | Base Salary and traditional benefits | To provide a base level of compensation for services performed, to encourage the continued service of our executive officers and to attract additional talented executive officers when necessary | Cash / throughout the fiscal year | | Annual Incentive Compensation | To attract, motivate and reward executives to achieve and surpass key performance target goals | Cash / typically in February based upon the prior fiscal year’s performance | | Long-Term Equity Incentive Compensation | To attract, motivate and reward executives to increase stockholder value, and encourage them to make long-term commitments to serve the Company | Restricted stock with performance and time vesting criterion / following the release of second quarter earnings |

  27. Annual Incentive Compensation

    Annual Incentive Compensation Each of our NEOs received annual incentive compensation for 2024 based upon the actual performance of the Company relative to the performance targets (as described below), which were established by the Committee on February 1, 2024. The table below shows the target annual incentive award for each of our NEOs. For 2024, the amount of incentive compensation payable to each of our named executive officers was calculated as follows:

  28. PERFORMANCE FACTOR

    | Performance to Target(1) | Payout Percentage | | 96% | 80% | | 100% | 100% | | 104% | 135% | | 106% | 185% | | 109% | 270% | | 112% | 350% | | 115% | 400% |

  29. PERFORMANCE FACTOR

    | (1) Incentive operating income is the performance criteria metric used for all bonus plans. Incentive operating income includes adjustments to operating income as presented in the Company’s audited financial statements for purposes of defining the performance criteria, such as: (i) certain standard adjustments made annually, including expenses associated with phantom shares granted to personnel in our European businesses and FIFO variances; and (ii) certain adjustments made when applicable, including impairment charges, certain gains or losses on the sale of assets, certain gains stemming from claim recoveries, consolidation related expenses and purchase accounting adjustments. | | (2) The performance targets applicable to our NEOs were established by the Committee on February 1, 2024, and continue the Company’s longstanding approach of establishing ambitious performance goals that would motivate and incentivize our NEOs to deliver value to our stockholders throughout the Company’s fiscal year. |

  32. Long-Term Equity Incentive Compensation Program

    Long-Term Equity Incentive Compensation Program

  33. OVERVIEW

    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, allocated as shown below. In 2024, to reaffirm 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 for Messrs. Christopher, Martin and Sigloch, and five years for Mr. Miritello. 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.

  34. VESTING SCHEDULE FOR PERFORMANCE-BASED RESTRICTED STOCK

    VESTING SCHEDULE FOR PERFORMANCE-BASED RESTRICTED STOCK To foster executive retention, 100% of the regular annual equity awards given to NEOs in 2024, all of which are performance-based, will cliff vest after a period of three years (or five years for Mr. Miritello). 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 of unvested shares of restricted stock in the event of death, disability or a change in control (as explained in more detail in the “2024 Grant of Plan Based Awards” and “Potential Payments Upon Termination of Employment or Change in Control as of the End of 2024” Tables). 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.

  35. VESTING SCHEDULE FOR PERFORMANCE-BASED RESTRICTED STOCK

    | (1) Mr. Miritello’s 2024 performance-based restricted stock award has a five-year vesting term and is therefore scheduled to vest on July 30, 2029. |

  36. PERFORMANCE CRITERIA FOR PERFORMANCE-BASED RESTRICTED STOCK

    PERFORMANCE CRITERIA FOR PERFORMANCE-BASED RESTRICTED STOCK Of the annual equity awards granted to our NEOs in 2024, 100% are performance-based, and vesting is contingent upon the Company’s performance as measured by an adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) metric. This single metric was utilized in 2024 to prioritize management’s enhanced attention to earnings and cash flow. Specifically, utilizing this metric ensures that annual performance-based awards to these NEOs will only vest based upon the achievement of specified earnings growth targets over a three-year performance period, which for the 2024 grants, was December 31, 2023 to December 26, 2026. For this purpose, the adjusted EBITDA metric means the total adjusted EBITDA achieved by the Company during the three-year performance period, as compared with a cumulative adjusted EBITDA target of $1.44 billion. The degree to which the annual equity awards granted to our NEOs vest is contingent upon the Company’s actual performance as compared with the adjusted EBITDA target. The table below illustrates the applicable achievement levels and corresponding vesting percentages based upon the adjusted EBITDA 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. ADJUSTED EBITDA METRIC

  37. PERFORMANCE CRITERIA FOR PERFORMANCE-BASED RESTRICTED STOCK

    | Achievement Percentage | Vesting Percentage | | 80% | 80% | | 100% | 100% | | 110% | 200% |

  38. PERFORMANCE CRITERIA FOR PERFORMANCE-BASED RESTRICTED STOCK

    To be clear, the adjusted EBITDA target established for our annual equity grants is 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 reflect the Company’s 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.

  39. TIMING OF LONG-TERM EQUITY AWARD GRANTS

    TIMING OF LONG-TERM EQUITY AWARD GRANTS Long-term equity incentive awards to our Chief Executive Officer and other NEOs are traditionally granted annually, 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. The NEOs received their annual grants on August 5, 2024. 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 2024, we awarded annual grants to our NEOs reserving an aggregate of 299,000 shares (assuming the maximum performance threshold is met).

  40. TIMING OF LONG-TERM EQUITY AWARD GRANTS

    | MUELLER INDUSTRIES • 2025 PROXY STATEMENT | 31 |

  41. TIMING OF LONG-TERM EQUITY AWARD GRANTS

    While we do not have a formal policy with respect to the timing of awards of stock options, stock appreciation rights, or similar option-like instruments, we do not typically grant, and since 2022 have not granted, such awards (other than a limited number of stock appreciation grants that we make from time to time to certain non-executive employees who are located outside of the United States, due to local law considerations). In the event we determine to grant new awards of stock options or similar awards in the future, the Committee will evaluate the appropriate steps to take in relation to the foregoing. We have not timed the release of material non-public information for purposes of affecting the value of executive compensation.

  42. COMPENSATION PROGRAM RISK CONSIDERATIONS

    | Pay Mix | • Compensation program includes an appropriately balanced mix of short and long-term incentives, which mitigates the risk of undue focus on short-term targets while rewarding performance in areas that are key to our long-term success. • Base salaries are set at competitive levels to promote stability and give executives an element of compensation that is not at risk. | | Performance Metrics and Goals | • Distinct performance metrics are used in both our short-term and long-term incentive plans. • Our annual incentive compensation program includes a payout scale (and cap) reflective of a pay for performance philosophy. | | Long-term Incentives | • Our long-term equity incentive program is designed to retain key executives and business leaders and to align their interests with those of our stockholders. |

    | (1) Represents the right to annual cash incentive awards that could have been earned based on performance in 2024. These columns show rights to awards that were possible at the threshold, target and maximum levels of performance for each NEO in 2024, determined by multiplying each NEO’s actual base salary paid during 2024, by the NEO’s incentive grade level factor, and then by a performance factor of 80% for the threshold level (for 96% achievement of the applicable performance criteria), 100% for the target level (for 100% achievement of the applicable performance criteria), and capped at 400%. | | (2) The vesting of shares of performance-based restricted stock granted to our NEOs on August 5, 2024 is conditioned upon the Company’s actual performance as compared with an adjusted EBITDA performance metric over a three-year reference period (December 31, 2023 to December 26, 2026). This column represents the aggregate grant date fair value of the awards granted to our NEOs computed in accordance with Financial Accounting Standards Board Accounting Standards Codification 718 and assuming the threshold, target and maximum performance condition are achieved as of such date. If 80% of the adjusted EBITDA target is met, the threshold number of shares are eligible for vesting on the Vesting Date (July 30, 2027 for Messrs. Christopher, Martin and Sigloch, and July 30, 2029 for Mr. Miritello). If 110% of the adjusted EBITDA target is met, the maximum number of shares are eligible for vesting on the Vesting Date.

The amount of outstanding options and the exercise prices shown in the above table are post-adjustments. | | (2) The vesting of shares of performance-based restricted stock granted to our NEOs in 2022-2024 is conditioned upon the Company’s actual performance as compared with an adjusted EBITDA target.

With respect to the 2022 grants, the values reflected in this table are based on actual performance during the reference period (which resulted in achievement of the maximum award amount). Otherwise, the values reflected in this table reflect the Company’s current estimate that the maximum awards will be achieved. The performance-based restricted stock grants described above are subject to earlier vesting in connection with a change in control or a termination of employment due to death or disability. If the acceleration event occurs prior to the end of an applicable reference period, the maximum award amount will vest. | | (3) Shares of time-based restricted stock granted to Mr. Christopher in 2020 vested or will vest 30% on each of the third and fourth anniversaries of the vesting commencement date (July 30 of the year of grant), and 40% on the fifth anniversary of the vesting commencement date, in each case, subject to earlier vesting in connection with a change in control or a termination of employment due to death or disability. |

  72. Pay Ratio

    Pay Ratio In 2024, the total compensation of Mr. Christopher, our Chief Executive Officer, was $22,786,901 as reported in the “Summary Compensation Table for 2024.” Based on the methodology described below, we determined that the median employee in terms of total 2024 compensation of all of our employees (other than Mr. Christopher) received an estimated $42,953 in total compensation for 2024. Therefore, the estimated ratio of 2024 total compensation of Mr. Christopher to the median employee was 531:1. 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 2024 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:

  73. Pay Ratio

    | • | We identified our employee population as of December 28, 2024, which consisted of approximately 5,168 employees. | | • | For each employee (other than Mr. Christopher), we determined the sum of his or her base salary for 2024, and incentive awards for 2024. Comparing the sums, we identified an employee whose compensation best reflects the Company employees’ median 2024 compensation, considering whether their compensation likely would reflect median employee compensation in future years. | | • | In accordance with SEC rules, we then determined that employee’s 2024 total compensation was $42,953 using the approach required by the SEC when calculating our named executive officers’ compensation, as reported in the Summary Compensation Table. |
