2021 ANNUAL MEETING OF SHAREHOLDERS | PROXY STATEMENT Martin Marietta 2021 Annual Meeting of Shareholders Proxy Statement A World-Class Organization Built for Success

##### Table of Contents

|  | April 13, 2021 |  |

Dear Fellow Shareholder:

On behalf of the Martin Marietta Board of Directors and executive officers, I am pleased to invite you to attend Martin Marietta’s 2021 Annual Meeting of Shareholders. This document provides some of the highlights of our key actions and important decisions in 2020 as well as information about our financial performance. Please review this Proxy Statement and the 2020 Annual Report for more information about these topics. Our Continuing Response to COVID-19 In this same letter last year, published in April 2020 at the beginning of the coronavirus (COVID-19) pandemic, I noted that our management and Board of Directors were actively monitoring emerging developments, preparing for and responding to the challenges and uncertainties posed by the pandemic, and proactively taking responsible steps across our enterprise to keep our business, including our employees, customers, vendors, and other stakeholders, safe and healthy. Throughout 2020 and as of the date of this letter, we have remained open for business and continued to meet the needs of our communities. This includes implementing enhanced facility and equipment cleaning, personal safety protocols, social distancing, remote work (where possible), and other changes, all of which we believe are consistent with the guidelines from the Centers for Disease Control and Prevention and the physicians associated with our industrial hygienist group that are familiar with our operations. We effectively established task forces related to COVID-19 planning and communications, canceled all non-essential business travel, and established contingency plans with respect to facility staffing. |  |

Record 2020 Financial Performance

Despite the challenges posed by COVID-19, 2020 was another outstanding year of achievement at Martin Marietta. We successfully managed as an essential business through the COVID-19 crisis with limited business disruption, achieving consolidated total revenues of $4.7 billion, which was driven by steady pricing gains in all product lines. While shipments were lower than the prior year due to headwinds from the global pandemic, we reported record financial results, including an 11% increase in Adjusted EBITDA, an 18% increase in Diluted EPS, and a 290 basis point increase in Adjusted EBITDA Margin from the prior year level. We increased our dividend 4% in August 2020 and returned $190.3 million to shareholders in 2020; we have returned more than $1.8 billion to shareholders since announcing a 20 million share repurchase authorization in February 2015.

Commitment to Sound Corporate Governance

We remained engaged with shareholders and other key stakeholders during 2020. In response to valuable feedback from shareholders, we continued to enhance our disclosure regarding our activities, risks and opportunities regarding sustainability and other environmental, social and governance issues, which is further addressed in the Sustainability section in this letter below. Our investor outreach in 2020 extended to 88 meetings (mostly virtual) with 313 investment groups in the United States, Canada, the United Kingdom, Germany, Switzerland, the Netherlands, and France, including most of our top 30 shareholders.

Over the past five years, we have added seven new independent directors. Most recently, Anthony R. Foxx, who served as the United States Secretary of Transportation and Mayor of Charlotte, North Carolina, joined the Board in November 2020, and David C. Wajsgras, who served as president of the Intelligence, Information and Services business of the former Raytheon Company, as well as its CFO, joined the Board in May 2020. We are delighted to have both Anthony and Dave, who each bring strong backgrounds and experience with publicly-traded companies and add unique insights into our Board mix. We also recognize the importance of diversity in our business and leadership, including on our Board. Our Board nominees demonstrate diversity in the form of gender, ethnicity, age and tenure, geography, and experience. Of note, women and ethnic minorities currently represent 45 percent of our Board.

World-Class Safety Performance

In 2020, we continued our impressive safety performance despite the challenges of the COVID-19 pandemic. Through the hard work and focus of our employees, safety awareness has remained high across the Company. Our employees know world-class safety performance is both critical and achievable; and, importantly, 2020’s results demonstrate we can continue to improve on our already strong safety record. Our company-wide Lost Time Incident Rate (LTIR) was 0.15, the fourth consecutive year of achieving world-class or better LTIR thresholds, and our Total Injury Incident Rate (TIIR) was 0.93, compared with 1.18 in 2019.

Sustainability

Since 2015, we have annually issued our Sustainability Report to share our story and provide information that we believe is responsive to requests from our shareholders and other stakeholders on the efforts and advancements we are making in these important areas. Since our first Sustainability Report in 2015, we have enhanced our reporting with more comprehensive descriptions of our outstanding safety and regulatory programs and performance, targeted and intentional support of education and health, and strong community involvement. In our sixth annual Sustainability Report issued in 2020, we included additional disclosure about our activities, accomplishments and opportunities associated with key sustainability matters, including those related to the environment. This included new disclosures of our direct greenhouse gas emissions across all of our business lines, as well as our emissions reductions targets for 2030. In our seventh Sustainability Report, to be issued in April 2021, we will provide additional information about greenhouse gas emissions related to our operations (including our indirect greenhouse gas emissions) and our efforts to achieve our commitments, including our community support during the COVID-19 pandemic. Our activities reflect that these matters continue to be part of our core approach and strategy that bring value to our shareholders and other stakeholders.

Your Vote Matters

I urge you to cast your vote promptly, either by returning the enclosed Proxy Card or by the electronic or telephone options described in our Proxy Statement – even if you plan to attend the Annual Meeting. We encourage you to vote so that your shares will be represented at the meeting.

On behalf of the entire Board of Directors, thank you for your continued investment in Martin Marietta. We look forward to continuing to deliver strong and responsible performance, innovation and growth to our customers, our shareholders and our other stakeholders.

Sincerely,

C. Howard Nye

Chairman of the Board, President and Chief Executive Officer

Effective Shareholder Engagement

Accountability to our shareholders is an important component of the Company’s success. We recognize the value of building informed relationships with our investors that promote further transparency and accountability. While proxy voting is one direct way to influence corporate behavior, proactive engagement with our investors can be effective and impactful. Investor views are communicated to the Board and are instrumental in the development of our governance, compensation and sustainability policies and inform our business strategy.

During 2020, we engaged in person through virtual meetings, by telephone and/or written correspondence with our largest institutional investors and other significant shareholders on an array of governance topics, including our executive compensation programs. We also engaged by telephone conference or written correspondence with stakeholders or other parties on various topics including board composition, executive compensation, human capital management, and ESG matters, as well as other topics of interest.

At our 2020 Annual Meeting of Shareholders, 95.4% of the shares cast voted in favor of the advisory vote on executive compensation, or Say On Pay. We made meaningful changes in 2018 to our compensation program based on feedback from shareholders consisting of:

• |  | The elimination of the excise tax gross-up in executive officers’ Employment Protection Agreements

• |  | The elimination of the walk-right and value of perks in the severance calculation in executive officers’ Employment Protection Agreements

• |  | The decision to not include these provisions in future Employment Protection Agreements

• |  | The elimination of the single-trigger vesting for equity awards beginning in 2019

PROXY ◆ OUR COMPENSATION APPROACH AND HIGHLIGHTS

Our Commitment to Our People and Pay-for-Performance

In 2020, we advanced our initiatives relating to engagement with our employees

✓ |  | Inclusion & Engagement Task Force

✓ |  | New Career Development Program providing employees with tools and resources for development, career opportunities, and succession planning

✓ |  | New High Deductible Healthcare Plan as a second healthcare plan alternative to employees

✓ |  | New Paid Time Off policy to enhance employee benefits package

Our Compensation Approach and Highlights

A substantial portion of compensation paid to our named executive officers (NEOs) is variable and performance-based. We use the 50th percentile of our peer group as a reference point when determining target compensation, but target pay is set based on a variety of factors and actual pay realized by our NEOs is dependent on our financial, operational and other related performance. Based on our record levels of performance in 2020, variable compensation payable under both our short-term and long-term incentive plans exceeded the target amounts established for each NEO, which is consistent with our pay-for-performance philosophy. All compensation paid to our CEO and other NEOs in 2020 was performance-based other than base salary: approximately 87% of our CEO’s compensation was performance-based and 74% of our other NEOs’ compensation was performance based.*

* Based on grant date value of Performance Share Units (PSUs) and Restricted Stock Units (RSUs).

The Board of Directors

The Board of Directors currently consists of eleven members, ten of whom are non-employee Directors. Under our Bylaws, nominations of persons for election to the Board may be made at an Annual Meeting of Shareholders by the Board and by any shareholder who complies with the notice procedures set forth in the Bylaws. As described in the Proxy Statement for our 2020 Annual Meeting, for a nomination to be properly made by a shareholder at the 2021 Annual Meeting, the shareholder’s notice must have been sent to, and received by, our Secretary at our principal executive offices between January 16, 2021 and February 15, 2021. No such notice was received during this period.

The Bylaws of the Company provide that a Director will retire at the Annual Meeting of Shareholders following the Director’s 75th birthday. None of our current Directors reached this mandatory retirement age this year.

The Board has nominated Anthony R. Foxx to stand for election by shareholders at the 2021 Annual Meeting. Mr. Foxx was first elected as a Director by the Board in November 2020. Mr. Foxx was initially identified by the Chairman, President and CEO and was recommended as a director nominee by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee from time to time retains a search firm to help identify director prospects, perform candidate outreach, assist in reference checks, and provide other related services. The recruiting process typically involves either the Chairman, President and CEO, the search firm or a member of the Nominating and Corporate Governance Committee contacting a prospect to gauge his or her interest and availability. A candidate will then meet with several members of the Nominating and Corporate Governance Committee and sometimes the Board. At the same time, the Nominating and Corporate Governance Committee and the search firm will contact references for the prospect. A background check is completed before a final recommendation is made to the Board to appoint a candidate to the Board.

The Board has nominated eleven persons for election as Directors to serve a one-year term expiring in 2022. Unless otherwise directed, proxies will be voted in favor of these nominees. Each nominee has agreed to serve if elected. Each of the nominees is currently serving as a Director. Should any nominee become unable to serve as a Director, the persons named in the enclosed form of proxy will, unless otherwise directed, vote for the election of such other person for such position as the present Board of Directors may recommend in place of such nominee. Proxies cannot be voted for a greater number of persons than the number of nominees named. Should any of the listed nominees be unavailable for election by reason of death or other unexpected occurrence, the proxy, to the extent permitted by applicable law, may be voted with discretionary authority in connection with the nomination by the Board and the election of any substitute nominee.

Board Effectiveness and Refreshment

Board composition is one of the most critical areas of focus for the Board of Directors. Having the right mix of people who bring diverse perspectives, business and professional experiences, and skills provides a foundation for robust dialogue, informed advice and collaboration in the boardroom. The Nominating and Corporate Governance Committee develops criteria for open Board positions, taking into account a variety of factors, which may include current Board member skills, composition, age, tenure, other diversity factors, the range of talents and experience that would best complement those already represented on the Board, the need for specialized expertise, and anticipated retirements to define gaps that may need to be filled through the Board refreshment process. The Board strives to ensure an environment that encourages diverse critical thinking and values innovative, strategic discussions to achieve a higher level of success for the Company.

The Nominating and Corporate Governance Committee screens and recommends candidates for nomination by the full Board. It uses a variety of methods to help identify potential Board candidates with the desired skills and background needed for the Company’s business, including from time to time informal networks, third-party search firms and other channels. When the Committee is assisted from time to time with its recruitment efforts by an outside search firm, the firm recommends candidates that satisfy the criteria defined by the Board, and provides background research and pertinent information regarding prospective candidates.

THE BOARD OF DIRECTORS ◆ BOARD EFFECTIVENESS AND REFRESHMENT

Once the Committee has identified a prospective nominee, it makes an initial determination as to whether to conduct a full evaluation. In making this determination, the Committee takes into account various information, including information provided at the time of the candidate recommendation, the Committee’s own knowledge, and information obtained through inquiries to third parties to the extent the Committee deems appropriate. The preliminary determination is based primarily on the need for additional Board members and the likelihood that the prospective nominee can satisfy the criteria that the Committee has established. If the Committee determines, in consultation with the Chairman, President and CEO and other Directors as appropriate, that additional consideration is warranted, it may request management or a third-party search firm to gather additional information about the prospective nominee’s background and experience and to report its findings to the Committee. The Committee then evaluates the prospective nominee against the specific criteria that it has established for the position, as well as the standards and qualifications set out in the Company’s Corporate Governance Guidelines, including:

• |  | the ability of the prospective nominee to represent the interests of the shareholders of the Company;

• |  | the prospective nominee’s standards of integrity, commitment and independence of thought and judgment;

• |  | the prospective nominee’s ability to dedicate sufficient time, energy and attention to the diligent performance of his or her duties, including the prospective nominee’s service on other public company boards, as specifically set out in the Company’s Corporate Governance Guidelines;

• |  | the extent to which the prospective nominee contributes to the range of talent, skill and expertise appropriate for the Board; and

• |  | the extent to which the prospective nominee helps the Board reflect the diversity of the Company’s shareholders, employees, customers and the communities in which it operates.

If the Committee decides, on the basis of its preliminary review, to proceed with further consideration, members of the Committee, the Chairman, President and CEO, as well as other members of the Board as appropriate, interview the nominee. After completing this evaluation and interview, the Committee makes a recommendation to the full Board, which makes the final determination whether to nominate or appoint the new Director after considering the Committee’s report. A background check is completed before a final recommendation is made to the Board to appoint a candidate to the Board.

In selecting nominees for the Board, the Board seeks to achieve a mix of members who together bring experience and personal backgrounds relevant to the Company’s strategic priorities and the scope and complexity of the Company’s business. The Board also seeks a demonstrated ability to manage complex issues that involve a balance of risk and reward. The background information on current nominees beginning on page 18 and the skills matrix on page 11 set out how each of the current nominees contributes to the mix of experience and qualifications the Board seeks. In making its recommendations with respect to the nomination for re-election of existing Directors at the annual shareholders meeting, the Committee assesses the composition of the Board at the time and considers the extent to which the Board continues to reflect the criteria set forth above.

|  | Board Refreshment Elements

Review of Board Candidates |  | The Board seeks a diverse group of candidates who, at a minimum, possess the background, skills, expertise and time to make a significant contribution to the Board, the Company and its shareholders. The Corporate Governance Guidelines list criteria against which candidates may be judged. In addition, the Nominating and Corporate Governance Committee considers, among other things: •input from the Board’s self-assessment process to prioritize areas of expertise that were identified; •investor feedback and perceptions; •the candidates’ skills and competencies to ensure they are aligned with the Company’s future strategic challenges and opportunities; and •the needs of the Board in light of recent and anticipated Board vacancies. During the process of identifying and selecting director nominees, the Nominating and Corporate Governance Committee screens and recommends candidates for nomination by the full Board. The Bylaws provide that the size of the Board may range from 9 to 11 members. Director candidates also may be identified by shareholders and will be evaluated under the same criteria applied to other director nominees and considered by the Nominating and Corporate Governance Committee. Information on the process and requirements for shareholder nominees may be found in our Bylaws on the Company’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters.
Board Assignments |  | Each February, the Nominating and Corporate Governance Committee reviews the membership, tenure, leadership and commitments of each of the Committees and considers possible changes given the qualifications and skill sets of members on the Board or a desire for committee rotation or refreshment. The Nominating and Corporate Governance Committee also takes into consideration the membership requirements and responsibilities set forth in each of the respective Committee charters and the Corporate Governance Guidelines as well as any upcoming vacancies on the Board due to our mandatory retirement age. The Nominating and Corporate Governance Committee recommends to the Board any proposed changes to Committee assignments and leadership to be made effective at the next Annual Meeting of Shareholders. The Nominating and Corporate Governance Committee also reviews the operation of the Board generally.
Refreshment |  | The Board has added seven new directors in the past five years. At the same time, obtaining a detailed understanding of the Company’s business takes time. We believe that implementing term limitations may prevent the Board from taking advantage of insight that longer tenure brings.
Annual Performance Assessment |  | The Board conducts a self-assessment of its performance and effectiveness as well as that of its Committees on an annual basis. The self-assessment helps the Nominating and Corporate Governance Committee track progress in certain areas targeted for improvement from year-to-year and to identify ways to enhance the Board’s and its Committees’ effectiveness. For 2020, each director completed a written questionnaire. The questions were open-ended to solicit candid feedback. The collective ratings and comments are compiled and summarized and then discussed by the Nominating and Corporate Governance Committee and the full Board.
Onboarding and Education |  | New directors are provided with an orientation about the Company, including our business operations, strategy and governance. Directors also are provided continuing education by subject matter experts and/or continuing education programs sponsored by educational and other institutions to assist them in staying abreast of developments in corporate governance and critical issues relating to the operation of public company boards. Members of our senior management regularly review with the Board the operating plan of each of our business segments and the Company as a whole. The Board also conducts periodic visits to our facilities as part of its regularly scheduled Board meetings.

|  | Tenure Guidelines

Mandatory Retirement Age |  | Directors must retire at the annual meeting following his or her 75th birthday.
Employment Change |  | Directors must report to the Chairman of the Board and Chairman of the Nominating and Corporate Governance Committee regarding any significant change in principal employment or responsibilities to assure he/she can continue to commit the appropriate time to Board service.

BOARD, COMMITTEE AND INDIVIDUAL DIRECTOR EVALUATIONS ◆ THE BOARD OF DIRECTORS

Board, Committee and Individual Director Evaluations

As a part of our continuous improvement process intended to enhance the Board’s overall effectiveness, the Board regularly evaluates its performance through self-assessments, corporate governance reviews and periodic charter reviews. Those evaluations, changes in our business strategy or operating environment, and the future needs of the Board in light of anticipated director retirements are used to identify desired backgrounds and skill sets for future Board members. The feedback solicited from Board members regarding the Board, each Committee on which they serve, and individual Board members is one of the tools used to assist the Nominating and Corporate Governance Committee in its responsibility to evaluate Board and Committee performance annually.

Board Committees

Martin Marietta’s Board of Directors has six standing Committees: the Audit Committee; the Ethics, Environment, Safety and Health Committee; the Executive Committee; the Finance Committee; the Management Development and Compensation Committee; and the Nominating and Corporate Governance Committee. Each Committee has a written charter that describes its purposes, membership, meeting structure, authority and responsibilities. These charters are reviewed by the respective Committee on an annual basis with any recommended changes adopted upon approval by our Board. The charters of our six standing Committees are posted on our website.

Martin Marietta uses a combination of cash and stock-based compensation to attract and retain qualified candidates to serve on the Board of Directors.

The Company reimburses Directors for the travel expenses of, or provides transportation on Company aircraft for, Board and Committee meetings, meetings with management or independent consultants or advisors, and other Company-related events, such as Investor Day and meetings with potential Board candidates. No Directors received personal use of Martin Marietta’s aircraft or other perquisites or personal benefits in 2020.

Equity Compensation Paid to Board Members

Non-employee Directors received an award of restricted stock units (RSUs) with a value of $130,000 (rounded up to the nearest RSU) based on the closing price as of the date of grant, which was generally immediately following the 2020 Annual Meeting of Shareholders in May 2020. In May 2020, this award was 770 RSUs. Mr. Foxx received his RSU award of 508 RSUs when he joined the Board. The RSUs granted to the Directors in 2020 were fully vested upon award. Directors are required to defer at least 50% of the RSUs until retirement from the Board. Directors may choose to voluntarily defer an additional portion of their RSUs, and any RSUs that are not so deferred are settled in shares of common stock of Martin Marietta as soon as practicable following the grant date. The RSUs were awarded under the Martin Marietta Amended and Restated Stock-Based Award Plan (the Stock Plan), which was approved by shareholders on May 19, 2016. The Stock Plan provides that, during any calendar year, no non-employee Director may be granted (i) restricted shares and other full-value stock-based awards, including RSUs, in respect of more than 7,000 shares of common stock of Martin Marietta or (ii) options or stock appreciation rights in respect of more than 20,000 shares of common stock of Martin Marietta.

The Directors do not have voting or investment power for their respective RSUs.

Deferred Compensation Program for Board Members

The Common Stock Purchase Plan for Directors provides that non-employee Directors may elect to receive all or a portion of their fees earned in 2020 in the form of Martin Marietta common stock units. If deferral is elected, there is a mandatory deferral minimum time of three years with, subject to certain restrictions, redeferrals at each Director’s election up to the date the person ceases to be a Director or the date that is one year and one month following the date that the person ceases to be a Director. Directors may elect to receive payment of the deferred amount in a single lump sum or in equal annual installments for a period of up to ten years. By resolution adopted by Martin Marietta’s Board of Directors on May 17, 2018, amounts deferred under the plan in common stock are credited toward units of common stock at 100% of the fair market value of the common stock (the closing price of the common stock as reported in The Wall Street Journal) on the date the Director fees would otherwise be paid. Prior to that, amounts deferred under the plan in common stock were credited toward units of common stock at a 20% discount from the fair market value of the common stock (the closing price of the common stock as reported in The Wall Street Journal) on the date the Director fees would otherwise be paid. There are no matching contributions made by Martin Marietta. Dividend equivalents are paid on the units at the same rate as dividends are paid to all shareholders. The Directors do not have voting or investment power for their respective common stock units. Directors may also elect to defer their fees into a cash-based account on the same basis. Amounts deferred under the plan in cash are credited with interest at the prime rate as of January 1 of that year.

Based solely on its review of copies of reports filed with the SEC, the Company believes that during fiscal year 2020, such filing requirements were timely satisfied except for (1) due to an administrative error, a Form 4 was filed one day late on behalf of each of Ms. Bar and Messrs.

Corporate Governance Matters

Corporate Governance Philosophy

Martin Marietta has a culture dedicated to ethical business behavior and responsible corporate activity, which we believe promotes the long-term interests of shareholders. This commitment is reflected in our Corporate Governance Guidelines, posted and available for public viewing on Martin Marietta’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters, which set forth a flexible framework within which the Board, assisted by its Committees, directs the affairs of Martin Marietta. The Guidelines address, among other things, the composition and functions of the Board of Directors, director qualifications and independence, Chief Executive Officer performance evaluation and management succession, Board Committees and the selection of new Directors.

Martin Marietta’s Code of Ethical Business Conduct has been in place since the 1980s and is regularly updated. It applies to all Board members, officers, and employees, providing our policies and expectations on a number of topics, including our commitment to good citizenship, promoting a positive and safe work environment, avoiding conflicts of interest, honoring the confidentiality of sensitive information, preservation and use of Company assets, compliance with all laws, and operating with integrity in all that we do. To implement the Code of Ethical Business Conduct, Board members, officers, and employees participate regularly in ethics training. There have been no waivers from any provisions of our Code of Ethical Business Conduct to any Board member or executive officer.

In addition, the Board believes that accountability to shareholders is a hallmark of good governance and critical to Martin Marietta’s success. To that end, management regularly engages with shareholders on a variety of topics throughout the year, including sustainability and governance, to ensure we are addressing their questions, thoughts and concerns, to seek input and to provide perspective on Company policies and practices. Feedback received during these discussions is shared with the Board and directly impacts deliberations on material topics. See discussion of our shareholder outreach on pages 6, 38 and 40.

The chart below provides a snapshot of Martin Marietta’s governance highlights.

Corporate Governance Board Practices

Who are Martin Marietta’s independent Directors?

All of Martin Marietta’s Directors are non-employee Directors except Mr. Nye. Mr. Nye neither sits in the executive sessions of the independent Directors (unless invited to attend for a specific discussion) nor does he participate in any action of the Board relating to any executive compensation which he may receive.

In assessing the independence of its members and nominees, the Board has adopted for Martin Marietta a set of Guidelines for Director’s Independence (Guidelines). The Guidelines are posted and available for public viewing on Martin Marietta’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters. These Guidelines reflect the rules of the NYSE, applicable requirements of the SEC, and other standards determined by the Board to be important in assessing the independence of Board members. The Board has determined that, other than Mr. Nye, all members of the Board are “independent” under these Guidelines, resulting in 91% of the Board being independent. The Board of Directors has determined that no Director (except Mr. Nye), or nominee, or any person or organization with which the Director or nominee has any affiliation, has a relationship with Martin Marietta that may interfere with his or her independence from Martin Marietta and its management. In making this “independence” determination, the Board considered other entities with which the Directors were affiliated and any business Martin Marietta had done with such entities.

CORPORATE GOVERNANCE MATTERS ◆ CORPORATE GOVERNANCE PHILOSOPHY

Do the independent Directors ever meet without management?

Martin Marietta’s Corporate Governance Guidelines adopted by the Board provide that at least two Board meetings each year will include an executive session of the non-employee Directors to discuss such topics as they may choose, including a discussion of the performance of Martin Marietta’s Chairman and Chief Executive Officer. In 2020, Martin Marietta’s independent Directors met at each regularly scheduled Board meeting, consisting of four times in executive session without management, in addition to executive sessions held by Committees of the Board. In 2020, all the independent Directors were non-employees.

What is the Board’s leadership structure?

Our Corporate Governance Guidelines provide that the Board’s policy as to whether the Chairman and CEO positions should be separate is to adopt the practice that best serves the Company’s needs at any particular time. The Nominating and Corporate Governance Committee and the Board discussed Board leadership alternatives in connection with combining the Chairman and CEO roles.

The Board believes that, at the present time, the Company is best served by allocating governance responsibilities between a combined Chairman and CEO and a Lead Independent Director with robust responsibilities. This structure allows the Company to present a single face to our constituencies through the combined Chairman and CEO position while at the same time providing an active role and voice for the independent directors through the Lead Independent Director.

Reasons for Combined Chair and CEO
Key highlights
•  The independent Board members believe that Mr. Nye has extensive experience in all facets of the building materials industry, in both the U.S. and with global competitors.
•  Mr. Nye has been effective in creating shareholder value through strategic acquisitions and divestitures, with achievement of expected synergies.
•  Mr. Nye has in-depth knowledge of safety, health, operational, environmental, and regulatory considerations that impact the business and oversight of management.
•  Mr. Nye has demonstrated his leadership and vision to guide the Board in its oversight of management with the development of three five-year strategic plans, with the current Strategic Operating Analysis and Review (SOAR 2025) discussed with and approved by the Board in August 2020.
•  Mr. Nye has engaged in an active investor relations program, including the Company’s Investor Day presentations, and leads the Board in understanding the perspective of the Company’s shareholders.
•  Mr. Nye is the only member of management on the Board.
•  Strong independent directors comprise 91% of the current Board, and open communications exist between Mr. Nye and the independent directors.

As a result of Mr. Nye’s tenure at Martin Marietta and strong performance as a leader since his election as CEO, the Board believes he is uniquely qualified through his experience, education and expertise to be the person who promotes strong and visionary leadership for our Board, as well as important recognition as the leader of Martin Marietta by our customers, employees and other constituencies. The Board also believes that Mr. Nye’s serving as both Chairman and CEO is appropriate taking into consideration the size and nature of our business, Mr. Nye’s effective and careful formulation and execution of our strategic plan, his established working relationship and open communication with our other Directors, both during meetings and in the intervals between meetings, the significant board-level experience of our independent Directors as a whole, the strong independent leadership and accountability to shareholders provided by 91% of our Directors being independent, the independent leadership provided by our Committee chairs, and our Board culture in which Mr. Nye and the other Directors are able to thoughtfully debate different points of view and reach consensus in an efficient manner.

CORPORATE GOVERNANCE PHILOSOPHY ◆ CORPORATE GOVERNANCE MATTERS

Does the Board have a Lead Independent Director?

In deciding that a combined Chairman and Chief Executive Officer position is the appropriate leadership structure for the Company at this time, the Nominating and Corporate Governance Committee and Board also recognized the benefit of independent leadership to enhance the effectiveness of the Board’s oversight role and communications between the Board and Mr. Nye. Accordingly, in November 2014, our Corporate Governance Guidelines were revised to provide that in the event the Chairman and Chief Executive Officer positions are held by one person, our independent Directors may designate a Lead Independent Director from among the independent Directors. The designation of the Lead Independent Director is to be made annually, with the expectation of the Board that the Lead Independent Director will be re-appointed for multiple, consecutive one-year terms. John J. Koraleski currently serves as the Lead Independent Director.

The responsibilities of the Lead Independent Director include:

• |  | Presiding at Board meetings when the Chairman is not present.

• |  | Presiding at executive sessions of the independent Directors, and meeting separately with the Chairman after executive sessions to review the matters discussed during the executive sessions.

• |  | Acting as a liaison between the Chairman and the independent Directors.

• |  | Suggesting to the Chairman agenda items for Board meetings and consulting with the Chairman regarding Board meeting schedules.

• |  | Calling, where necessary, executive sessions of independent Directors.

• |  | Being available to meet with shareholders and other key constituents.

• |  | Acting as a resource for, and counsel to, the Chairman.

• |  | In addition, the Lead Independent Director attends and meets with shareholders at Company-sponsored Investor Days.

What is the Board’s role in risk oversight?

Our Board currently has ten independent members and only one non-independent member, Mr. Nye. A number of our independent Board members are serving or have served as members of senior management of other public companies, have served as directors of other public companies, and otherwise have experience and/or educational backgrounds that we believe qualify them to effectively assess risk. Each of our Board Committees, including our Audit, Management Development and Compensation, and Nominating and Corporate Governance Committees, are comprised solely of independent Directors, each with a different independent Director serving as Chair of the Committee (other than the Executive Committee, which does not meet on a regular basis).

The Board has overall responsibility for oversight of risk management. The Board believes that an effective risk management system will (1) timely identify the material risks that Martin Marietta faces, (2) communicate necessary information with respect to material risks to senior executives and, as appropriate, to the Board or relevant Board Committee, (3) determine whether the risk is excessive or appropriate under the circumstances and designed to achieve a legitimate corporate goal, (4) implement risk management responses consistent with Martin Marietta’s risk profile, and (5) integrate risk management into Martin Marietta’s decision-making.

The Board delegates certain responsibilities to the Committees to assist in fulfilling its risk oversight responsibilities. Each of the Committees reports regularly to the full Board of Directors as to actions taken and topics discussed. In addition, the Board regularly reviews with management the most significant risks facing Martin Marietta, the probabilities of those risks occurring, the steps taken to mitigate any impact of risks, and management’s general risk management strategy. In addition, the Board encourages management to promote a corporate culture that incorporates risk management into Martin Marietta’s day-to-day operations.

The Board has designated the Audit Committee to take the lead in overseeing risks related to financial reporting, financial statements, internal control environment, internal audit, independent audit, cybersecurity, and accounting processes. The Finance Committee evaluates risks associated with Martin Marietta’s capital structure, including credit and liquidity risks. The Management Development and Compensation Committee oversees aspects of risk related to the annual performance

CORPORATE GOVERNANCE MATTERS ◆ CORPORATE GOVERNANCE PHILOSOPHY

evaluation of our Chief Executive Officer, succession planning and ensuring that executive compensation is appropriate to meet Martin Marietta’s objectives. That Committee’s assessment of the design features of our executive compensation program that reduce the risk of excessive risk-taking are discussed in the Compensation Discussion and Analysis on page 37. The Nominating and Corporate Governance Committee oversees aspects of risk related to the composition of the Board and its Committees, Board performance and best practices in corporate governance. The Ethics, Environment, Safety and Health Committee monitors risks for the Company in key areas of Martin Marietta’s sustainability program, including health, safety, and the environment as well as the Company’s ethics program.

While the Board oversees Martin Marietta’s risk management, the executive officers are responsible for the day-to-day risk management processes. We believe this division of responsibilities is the most effective approach for addressing the risks facing our Company and is appropriate whether the positions of Chairman and Chief Executive Officer are separate or held by the same individual.

How would interested parties make their concerns known to the independent Directors?

The Board of Directors provides a process for shareholders and other interested parties to send communications to the Board. Shareholders and other interested parties may communicate anonymously and confidentially with the Board through Martin Marietta’s Ethics Hotline at +1 (800) 209-4508. The Board has also designated the Corporate Secretary to facilitate communications to the Board. Shareholders and other interested parties may communicate directly with the Board of Directors, or directly with the independent Directors, or an individual Director, including the Lead Independent Director, by writing to Martin Marietta, Attn: Corporate Secretary, 4123 Parklake Avenue, Raleigh, North Carolina 27612.

All communications by shareholders or other interested parties addressed to the Board will be sent directly to Board members. While Martin Marietta’s Ethics Office and the Corporate Secretary may review, sort, and summarize these communications, all direct communications will be presented to the independent Directors unless there is instruction from them to filter such communications (and in such event, any communication that has been filtered out will be made available to any independent Director who wishes to review it).

Martin Marietta and its Board of Directors will continue to review and evaluate the process by which shareholders or other interested persons communicate with Martin Marietta and the Board and may adopt other or further processes and procedures in this regard. If so, we will identify those policies and procedures on our website at www.martinmarietta.com.

How often did the Board meet during 2020?

Martin Marietta’s Board of Directors held four regularly scheduled meetings during 2020. There were also a total of 25 Committee meetings in 2020. In addition, management confers frequently with its Directors on an informal basis to discuss Company affairs.

How many times did Directors attend meetings of the Board and its Committees?

In 2020, all Directors attended 100% of the meetings of the Board of Directors during their term of service on the Board. All Directors attended at least 75% of the meetings of the Committees of the Board on which they served (during the periods that they served).

Will the Directors attend the Annual Meeting?

Martin Marietta’s Directors are expected to be available by telephone conference to respond to questions and react to comments at the Martin Marietta’s Annual Meeting of Shareholders although frequently no Shareholders other than Directors and Officers attend these meetings. In 2020, all then-current Directors participated by telephone conference the Annual Meeting in May.

Will the Nominating and Corporate Governance Committee consider any Director candidates recommended by shareholders?

The Nominating and Corporate Governance Committee will consider nominees recommended by shareholders for election as a Director at an Annual Meeting of Shareholders of Martin Marietta, if the shareholder making such recommendation complies with the advance notice provisions and other criteria specified in the Bylaws of Martin Marietta. The Bylaws of

CORPORATE GOVERNANCE PHILOSOPHY ◆ CORPORATE GOVERNANCE MATTERS

Martin Marietta require advance notice for any proposal for the nomination for election as a Director at an Annual Meeting of Shareholders that is not included in Martin Marietta’s Notice of Meeting or made by or at the direction of the Board of Directors. In general, nominations must be delivered to the Secretary of Martin Marietta at its principal executive offices, 4123 Parklake Avenue, Raleigh, North Carolina 27612, not less than 60 days nor more than 90 days prior to the first anniversary of the mailing of the Proxy Statement in connection with the preceding year’s Annual Meeting of Shareholders and must contain specified information concerning the nominee and the shareholder proposing the nomination. Any shareholder desiring a copy of the Bylaws of Martin Marietta will be furnished a copy without charge upon written request to the Secretary of Martin Marietta. Since the 2020 Annual Meeting, Martin Marietta has not made any material changes to the procedures by which shareholders may nominate individuals for election as Directors. Additional information is contained in the section entitled Shareholders’ Proposals For 2022 Annual Meeting below.

How does the Board select nominees for the Board?

The Nominating and Corporate Governance Committee will consider candidates for Board membership suggested by its members and other Board members, as well as management and shareholders. The Committee may also retain a third-party executive search firm to identify potential candidates for its consideration from time to time. The Committee makes an initial determination as to whether to conduct a full evaluation of the candidate, and reviews all information provided to the Committee, including the recommendations for the prospective candidate and the Committee’s own knowledge of the prospective candidate. If the Committee determines that additional consideration is warranted, interviews are conducted by the members of the Committee, as well as the Chief Executive Officer of Martin Marietta; appropriate inquiries are conducted into the background and qualifications of potential candidates; the Committee meets to discuss its evaluation and feedback from the Chief Executive Officer; and, if the Committee determines to do so, it makes a recommendation to the full Board as to the persons who should be nominated by the Board. The Board of Directors determines the nominees after considering the recommendation and report of the Committee.

In evaluating any potential candidate, the Nominating and Corporate Governance Committee considers the extent to which the candidate has the personal characteristics and core competencies outlined in the Guidelines for Potential New Board Members adopted by the Committee, and takes into account all other factors it considers appropriate. A copy of these Guidelines is attached to this Proxy Statement as Appendix A.

Do the Board Committees have charters? How can shareholders obtain them?

Martin Marietta’s Board of Directors has adopted written charters meeting the requirements of the NYSE for the Audit Committee, Management Development and Compensation Committee, and Nominating and Corporate Governance Committee. These charters address the purposes and responsibilities of each Committee, as described above, and provide for an annual performance evaluation of each Committee. Copies of these charters, and the charters of the other Committees of the Board, are posted on Martin Marietta’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters, along with copies of Martin Marietta’s Corporate Governance Guidelines, Code of Ethical Business Conduct, and Guidelines for Director’s Independence.

How are transactions with persons related to Martin Marietta reviewed?

The SEC requires Martin Marietta to disclose in this Proxy Statement certain transactions in which Martin Marietta participates and in which certain persons considered “related persons” of Martin Marietta have a direct or indirect material interest. These “related persons” would include the Directors and executive officers of Martin Marietta, nominees for Director, certain control persons, and their immediate family members. Since January 1, 2020, there have been no such transactions.

Each Director, executive officer, and nominee for Director of Martin Marietta receives and agrees to abide by Martin Marietta’s Code of Ethical Business Conduct. Martin Marietta considers that any transaction in which Martin Marietta participates and in which any related person of Martin Marietta has a direct or indirect material interest will be subject to review, approval or ratification, as appropriate under the circumstances, by Martin Marietta under the standards enumerated in Martin Marietta’s Code of Ethical Business Conduct. If a proposed transaction is one in which a Director of Martin Marietta has an actual or potential conflict of interest, it will be subject to review by the Chairman of the Board of Directors and the Chairman of the Nominating and Corporate Governance Committee.

CORPORATE GOVERNANCE MATTERS ◆ CORPORATE GOVERNANCE PHILOSOPHY

Any waivers of the Code of Ethical Business Conduct for Directors and executive officers may be made only by Martin Marietta’s Board of Directors or any Committee to which it delegates that authority. Any waivers for Directors and executive officers and any amendments to the Code of Ethical Business Conduct will be promptly disclosed on our website, www.martinmarietta.com.

In assessing the independence of its members, the Board considers any interests a director may have in any transactions in which Martin Marietta participates. The Board also considers other entities with which the Directors are affiliated and any business Martin Marietta has done with such entities.

Proposal 2: |  | Independent Auditors

The Audit Committee has appointed PricewaterhouseCoopers LLP (PwC), an independent registered public accounting firm, to audit the consolidated financial statements of Martin Marietta and the effectiveness of Martin Marietta’s internal control over financial reporting for the 2021 fiscal year and the Board of Directors recommends that the shareholders ratify this appointment. The ratification of the appointment of PwC is being submitted to the shareholders because the Board of Directors believes this to be good corporate practice. Should the shareholders fail to ratify this appointment, the Audit Committee will review the matter and determine, in its sole discretion, whether PwC or another independent registered public accounting firm should be retained.

PwC served as Martin Marietta’s independent auditors for 2020 and audited the consolidated financial statements of Martin Marietta for the year ended December 31, 2020 and the effectiveness of Martin Marietta’s internal control over financial reporting as of December 31, 2020. In connection with the audit of Martin Marietta’s 2020 consolidated financial statements, Martin Marietta entered into an engagement letter with PwC that sets forth the terms by which PwC would perform audit services for Martin Marietta.

The Audit Committee is solely responsible for retaining or terminating Martin Marietta’s independent auditors. Representatives of PwC are expected to attend the Annual Meeting, will have the opportunity to make a statement if they so desire, and will be available to respond to questions from shareholders.

CORPORATE GOVERNANCE PHILOSOPHY ◆ CORPORATE GOVERNANCE MATTERS

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax services, and other services performed by its independent auditor. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent auditor is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to approve permitted services, provided that the Chair reports any decision to the Committee at its next scheduled meeting.

Audit Committee Review

In connection with the Audit Committee’s review of services rendered and fees billed by the independent auditor, the Audit Committee has considered whether the provision of the non-audit related services described above is compatible with maintaining the independent auditors’ independence and has concluded that the provision of these services did not compromise such independence.

Audit Committee Report

The Audit Committee operates under a written charter adopted by the Board of Directors, which is reassessed at least annually for adequacy by the Audit Committee. The Directors who serve on the Audit Committee have no financial or personal ties to Martin Marietta (other than Director compensation and equity ownership as described in this Proxy Statement) and are all “independent” for purposes of the SEC’s regulations, the NYSE listing standards, and the Guidelines for Director’s Independence adopted by the Board of Directors. The Board of Directors has determined that none of the Audit Committee members has a relationship with Martin Marietta that may interfere with the Director’s independence from Martin Marietta and its management. Copies of the Audit Committee’s charter and Martin Marietta’s Guidelines for Director’s Independence can be viewed on Martin Marietta’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters.

The Board of Directors has charged the Audit Committee with a number of responsibilities, including review of the adequacy of Martin Marietta’s financial reporting, accounting systems, and internal controls. Martin Marietta’s independent auditors and the vice president of the internal audit function report directly and are ultimately accountable to the Audit Committee.

In the discharge of its responsibilities, the Audit Committee has reviewed and discussed with management and the independent auditors Martin Marietta’s audited consolidated financial statements for fiscal year 2020 and has discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB), the SEC and the NYSE. In addition, the Committee has discussed with the independent auditors matters such as the quality (in addition to acceptability), clarity, consistency, and completeness of Martin Marietta’s financial reporting, as required by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the PCAOB).

The Audit Committee has received from the independent auditors written disclosures and a letter concerning the independent auditors’ independence from Martin Marietta, as required by the PCAOB in Rule 3526, Communication with Audit Committees Concerning Independence, and has discussed with the independent auditors the independent auditors’ independence. These disclosures have been reviewed by the Committee and discussed with the independent auditors.

Based on these reviews and discussions, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in Martin Marietta’s 2020 Annual Report on Form 10-K for filing with the SEC.

Letter from Committee Chair

Dear Fellow Shareholders:

Due to the pandemic and related economic disruption, 2020 was a very challenging year for Martin Marietta as well as the entire country and economy. During these unprecedented times, we have taken action to support our employees, their families, our customers, our supply chain, and the communities we serve. We are proud of our workforce, which has demonstrated the needed resilience to be successful. Despite the significant economic uncertainty and headwinds created by the COVID-19 pandemic, Martin Marietta achieved substantial success in meeting our strategic, financial and social objectives.

In the face of these challenges, we remain committed to maintaining strong executive pay and governance practices in which compensation is tied to performance. We look at a broad range of criteria when assessing performance, including financial, engagement with our shareholders, safety and health, our employees’ well-being, sustainability and others. These factors, which I’ve summarized, are discussed in detail below in the CDA. The Committee retained Pay Governance, a leading independent consulting firm, to help in this regard.

Financial Performance

As a result of our commitment to SOAR and proactive management of the business through the pandemic, 2020 was a year of continuing growth for Martin Marietta despite the challenges and uncertainty resulting from COVID-19. For the ninth consecutive year, the Company achieved annual products and services revenue, gross profit, adjusted EBITDA and adjusted EPS growth.

Note: See Appendix B for a reconciliation of non-GAAP measures to GAAP measures.

Engagement with Our Shareholders

We regularly engage with our shareholders to understand the executive compensation topics that matter most to them. We view a continuing, constructive dialogue with our long-term shareholders as critically important to ensuring that we remain aligned with their interests. We regularly talk to long-term shareholders and appreciate the opportunity to gain further insight and understanding into their views. Typically, management speaks with at least our top 25 shareholders, representing approximately 64% of our outstanding shares, at least annually. In 2020 our investor relations outreach extended to 88 meetings (mostly virtual) with 313 investment groups in the United States, Canada, the United Kingdom, Germany, Switzerland, the Netherlands, and France.

Safety

We have adopted a safety culture built on Guardian Angel, a safety program we first introduced in 2000 to

encourage our employees to look out for each other to make sure everyone goes home safely each day. This

program has propelled us to new heights in safety performance. In 2020, we rolled out a comprehensive

safety mentoring process to pair new employees with committed safety champions.

Our Employees

Martin Marietta recognizes that our success would not be possible without our hard-working and loyal employees, and our Guardian Angel safety program and ONE employer brand form the foundation of our exceptional Company culture.

◆ LETTER FROM COMMITTEE CHAIR

Rooted in our values of safety, integrity, excellence, community and stewardship, and driven by our World-Class vision, our employees demonstrated exceptional commitment in 2020, following strict COVID-19 protocols to keep their coworkers, communities and family members safe, while continuing essential business operations with minimal disruption. While keeping employees safe and healthy has been the Company’s priority since before the onset of the COVID-19 pandemic, we also made progress on a variety of other important employee-related initiatives in 2020. Importantly, we also formalized our efforts to increase diversity in our workplace with the formation of our Inclusion and Engagement Steering Committee, comprised of employees with diverse race, gender, background, experience and other factors. We believe this will also drive us to be better and attract the best talent available.

One of this Committee’s most important responsibilities is ensuring that our employees and management team are incentivized and rewarded when they achieve excellent performance. We are also focused on the appropriate development of our management team by providing opportunities to learn, expand their skill sets, and have opportunities available to them. We pride ourselves on saying that our employees come to Martin Marietta not for a job, but for a career. These objectives are an important part of maintaining a company that is sustainable, resilient and capable of delivering long-term growth.

Sustainability

Sustainability is part of our core strategy and Martin Marietta has a long track record of building solid foundations, caring about our employees, our communities and the environment, while responsibly growing our company. One of our commitments to our shareholders and other stakeholders is to improve each year on these metrics. In addition, we have endeavored to tell our story better each year, informing our shareholders and other stakeholders about our efforts, costs, risks, goals, and the relationship between our goals and management compensation. In 2020 we advanced this objective by providing enhanced disclosure regarding our carbon footprint and other environmental matters, including setting our goals for reduction by 2030.

Executive Compensation in 2020

The Committee believes that our executive compensation programs should evolve and be adjusted over time to support the achievement of our business goals, to reflect our challenges, and to promote near- and long-term shareholder value. During 2020, the Committee reviewed and evaluated market trends and best practices in designing and implementing elements of our compensation program. The Committee continues to believe that the goals for our executive compensation programs are to attract talented managers and incentivize and reward achievements that create value for our shareholders.

Our annual incentives are based on the achievement of various performance metrics, including overall financial

performance, shareholder returns, safety performance, sustainability, environmental and regulatory compliance results, management of working capital, and organic and inorganic growth. In addition, after the start of the COVID-19 pandemic and as further described below, the Committee created a “Resilience Scorecard” to align our executive and employee teams with maintaining our health and safety. We view this Resilience Scorecard as a tool we can use to assess whether the Company’s long-term success is durable and sustainable.

Our long-term incentives are designed to align executives with shareholder interests and to tie incentives with long-term goals. To ensure our plans achieve these goals, we conduct an annual assessment of compensation practices, which are more fully described below.

We believe that our executive incentive plans are highly motivational and create alignment with our performance and the shareholders’ experience. For 2020, as described above, our excellent industry-leading financial performance yielded an award of 190% of target for the annual incentive and an achievement of 200.8% under the Performance Share Units against the targets set for the 2018-2020 performance period. This is a shareholder aligned outcome.

In closing, the Committee believes that we have a very robust business model that yields attractive increases in shareholder value and positions us well for the future. Our executive compensation program helps drive those goals, and rewards our management and employees when they are achieved. We appreciate your support and welcome your feedback on our executive compensation programs and look forward to ongoing dialogue.

Sincerely,

John J. Koraleski, Chair

Management Development and Compensation Committee

At our 2020 Annual Meeting of Shareholders, 95.4% of the shares cast voted in favor of the advisory vote on executive compensation, or Say On Pay vote.

Our 2020 Performance

Building on prior-year success and demonstrating the resiliency of our business in challenging circumstances, 2020 proved to be another year of outstanding financial and safety performance for Martin Marietta. We functioned as an essential business during the COVID-19 pandemic in 2020 with limited business disruption, achieving consolidated revenues of $4.7 billion, consistent with the prior year, which reflected steady pricing gains in all product lines offsetting a modest decline in aggregates shipments. While aggregates shipments were lower than the prior year due to headwinds from the global pandemic, we reported record financial results with an increase of 11% in Adjusted EBITDA, 290 basis point improvement in Adjusted EBITDA Margin, and 18.5% increase in Diluted Earnings Per Share from the prior year level.

Despite a year filled with unprecedented disruption caused by the COVID-19 pandemic, we achieved our ninth consecutive year of growth for products and services revenues, adjusted gross profit, Adjusted EBITDA and adjusted earnings per diluted share (after adjusting for the one-time earnings per diluted share benefit in 2017 resulting from the Tax Cuts and Jobs Act of 2017). Additionally, we delivered the best safety performance in our Company’s history.

◆ SUMMARY OF OUR COMPENSATION CONSIDERATIONS

In 2020, we completed our latest five-year strategic planning process, or Strategic Operating Analysis and Review (SOAR), as previously scheduled before the COVID-19 pandemic began. The SOAR process, supplemented by our annual plan, has guided us since 2010 as we have grown the business in an intentional, contemplative, and disciplined manner. SOAR 2025 sets ambitious yet achievable targets for future growth and value creation.

Our impressive performance since 2010 reflects our resiliency, disciplined management, and the power of the SOAR process:

2020 Highlights

|  | Consolidated revenues of $4.7 billion, reflecting pricing growth in all product lines of our Building materials business, that offset the impact of lower aggregates shipments due to COVID-19
|  | Achieved 9th consecutive year of growth in products and services revenues gross profit, adjusted EBITDA and adjusted earnings per diluted share growth (after adjusting for the one-time earnings per share benefit in 2017 resulting from the Tax Cuts and Jobs Act of 2017)
|  | Record-setting results from 2015 to 2020 yielded a 5-year TSR of 118% versus the S&P 500 return of 103% during the same period

Disciplined Capital Allocation

|  | $75 million contributed to the Company’s qualified pension plan, resulting in a fully-funded plan
|  | Repurchased 211,000 shares for $50 million ($237.40 per share); 13.5 million shares remaining on our February 2015 authorization
|  | Board approved a 4% quarterly dividend increase ($2.28/share on an annualized basis) in August, continuing the Company’s track record of dividend growth
|  | Maintained our investment grade credit rating, exiting the year with a 1.9x leverage ratio

Martin Marietta’s ability to consistently translate revenue growth into increased profitability has also given us the ability to protect our balance sheet in order to make prudent acquisitions and capital investments in our business, while achieving a debt-to-EBITDA leverage ratio of 1.9x at year-end. As a result, we have been able to position our business as an aggregates leader in 90% of the geographies in which we operate and align our product offerings to leverage strategic cement and targeted downstream opportunities. This led to our significant outperformance of our peers over the five-year period ended December 31, 2020, during which time we delivered a 118 percent total shareholder return.

SUMMARY OF OUR COMPENSATION CONSIDERATIONS ◆

Sustainability, Safety and the Health of Our Employees During the COVID-19 Pandemic

Our sustainability efforts and our commitment to our employees go hand-in-hand. We discuss these important topics in several places in our public filings, including our annual Sustainability Report and our Annual Report on Form 10-K for the year ended December 31, 2020 where we discuss the importance of Human Capital to our Company. We encourage you to read those materials. In this section, we would like to highlight several of these topics and tell you about our achievements in these areas-namely, what Sustainability means to us generally, Environmental Stewardship, Safety, and Our Employees.

Sustainability

Our approach to Sustainability is embedded in four vital pillars of Safety, Environment, Employees, and Community. We continued to achieve improvements in each of these areas in 2020.

Safe Operations Protecting all who come in contact with our products & operations, and creating a culture of responsible leadership |  | Environmental Stewardship Protecting the Earth’s resources and reducing our environmental impact |  | Employee Well-Being Support and investing in our people – the foundation of our success |  | Community Well-Being Being a responsible neighbor and supporting the communities that are home to our operations

Track records such as ours are built purposefully; they are the result of a deliberate focus on fulfilling our responsibilities to our shareholders, our employees and other stakeholders. These responsibilities include:

|  | Demanding and facilitating a safe, ethical workplace for our employees |  |  |  | Creating a positive, lasting impact on our communities and the environment |  |  |  | Growing our business and responsibly investing our capital for maximum return

In furtherance of these continuing commitments, we have: •Included performance relating to Environment, Health, Safety and Sustainability (collectively, EHS) in our management strategy •Considered achievement of individual and company-wide goals in regard to EHS in management compensation decisions •Developed a task force relating to Sustainability with a view towards assessing and improving Company performance and disclosure against world-class achievements •Report regularly, at least twice annually, our progress on EHS issues to our Ethics, Environment, Health and Safety Committee (EESHC), an independent Committee of the Board of Directors

These critical matters are important to this Committee, the full Board, and management of Martin Marietta.

SOAR, supplemented by our annual plan, has guided us since 2010 as we have grown our business, driven our safety incidents to record low levels, achieved record financial performance and created positive impacts on our communities and the environment. Key managers from across our business and our senior leadership team engage throughout the year on material topics, including safety, employee well-being, community well-being and the environment.

42 2021 PROXY STATEMENT |  |  |  |

##### Table of Contents

◆ SUMMARY OF OUR COMPENSATION CONSIDERATIONS

Both SOAR and our annual plan are reviewed and endorsed by all members of our Board of Directors. Our EESHC is an experienced, diverse and knowledgeable group and has for decades overseen our ongoing efforts to hone truly sustainable business practices. Our full Board visits our operations frequently to hear firsthand from our team and see the positive impact we have on our communities. |  | Sustainability is a key component of our strategy and business plan at Martin Marietta. Sustainability excellence is not only the right thing to do and a key driver of shareholder value, it is a vital component of both our strategic planning process, SOAR, and our annual planning process.

|  | Environmental Stewardship |  |

We have made the following enhancements to our Sustainability activities:

• |  | In our 2019 Sustainability Report, issued in April 2020, we reported our Scope 1 greenhouse gas (GHG) emissions across all business lines for the first time. In that report, we also disclosed Scope 1 GHG emissions reduction targets across both our cement and magnesia specialties operations, which are the sources of most of our Scope 1 GHG emissions, for 2030 over a 2010 baseline year.

• |  | Our 2020 Sustainability Report, which will be issued in April 2021, we will expand the extensive disclosures included in our 2019 Sustainability Report. These will include additional key sustainability matters, such as Scope 2 GHG emissions data across all of our business lines.

• |  | Our Chairman and CEO, joined by other senior managers, engaged with six of our largest shareholders in 2020 specifically on Sustainability issues. In addition, we discussed Sustainability issues with almost all of 313 investor groups we met with through virtual conferences, roadshows, field trips, and group meetings during the year.

|  | Safety |  |

2020 was our safest year on record which strengthens our belief that Zero is Possible. This means operating our business without any safety incidents. Our goal is zero. We look to world-class companies and safety incident rates for guidance as to how we achieve this. We have continued to make headway in 2020 towards this important goal.

Several of our facilities were recognized by the National Stone, Sand and Gravel Association (NSSGA) as Safety Excellence Award winners. These awards recognize operations that have gone the longest duration without a reportable incident in their size category, based on data provided by the U.S. Department of Labor’s Mine Safety and Health Administration. In 2020, our Benson Quarry and Onslow Quarry in North Carolina won gold-level honors, while our Charlotte Quarry in North Carolina earned a silver award, and our Moore Quarry in Iowa and San Pedro Quarry in Texas received bronze awards. As an enterprise, Martin Marietta received bronze-level honors in the large company category by the NSSGA in its Louis Greisemer Silver Safety Awards.

The National Mining Association’s Sentinels of Safety Award recognizes coal and mineral mining operations in 10 categories for recording the most hours in a calendar year without a single lost-time injury. A minimum of 4,000 hours is required for award consideration. The award categories reflect the safety accomplishments of both small and large mines. |  | Our Chattanooga Quarry was recognized by being awarded the National Mining Association’s prestigious Sentinels of Safety Award.

##### Table of Contents

SUMMARY OF OUR COMPENSATION CONSIDERATIONS ◆

We achieved our fourth consecutive year of world-class

Lost-Time Incident Rate (LTIR) performance

Achieving World-Class Safety: LTIR |  | Safest Year on Record: TIIR

Note: Safety data current as of 12/31/20. LTIR per 200,000 hours worked. World-class levels based on general industries.

For Martin Marietta, safety performance sets our foundation for long-term financial strength and successful SOAR execution. Simply said, a safe operation is a profitable one. All awards are meaningful, but it is particularly satisfying when we are recognized for achievement of one of our core values.

|  | Our Employees |  |  |  |

|  | We implemented a new Personal Time Off (PTO) policy in April 2020 that provides employees with an increase in PTO benefits each year, and we continued to enhance our competitive offering of employee health, welfare and retirement benefits as well. We also launched an Inclusion and Engagement Task Force which is focused on hiring, developing, and retaining diverse employees. Through these important efforts in 2020, we continued to build a compelling connection with current and potential employees, increase the visibility and attractiveness of Martin Marietta as an employer of choice to strengthen our talent pipeline, and increase employee engagement, morale and retention.

|  | Diversity and Inclusion at a Glance

40% |  | of workforce are minorities |  |  |  | 33% |  | of workforce are racial/ethnic minorities |  |  |  | 10% |  | of workforce are women

We are committed to fostering diversity and inclusion, and strive to maintain a culture and adherence to core values that attract and celebrate diversity in our workplace. We believe that diversity promotes creativity, innovation, and mutual respect, which are all core to our values. We recognize that the unique viewpoints and experiences of every employee are important to achieving our mission to be a world-class organization, and have implemented initiatives that we believe will allow us to continue to improve on those objectives.

Although we do not necessarily believe that the Equal Employment Opportunity Commission data required on Form EEO-1 fully reflects our job-role structure, we will start making the data available on our website by 2022.

◆ SUMMARY OF OUR COMPENSATION CONSIDERATIONS

Compensation Decisions Yielding Alignment with Performance and Enhancing Our Corporate Resilience

As described below under 2020 Actual Incentive Cash Earned, the objective financial metrics in our annual plan that were measured for purposes of the 2020 Annual Cash Incentive were Pre-Tax Earnings and EBITDA, which are viewed as indicative of the Company’s profitability, and Days Sales Outstanding (DSO), which is viewed as indicative of the Company’s cash flow. All of these are important measures reflecting our performance and the creation of value for shareholders. In addition, the Committee considered the following, which are also described on pages 40-41 under Summary of Our Compensation Considerations:

• |  | A detailed assessment of Martin Marietta’s overall financial performance and each segment’s financial performance, including the highlights and the challenges.

• |  | Shareholder returns, including the consistent delivery of value to Martin Marietta’s shareholders.

• |  | Our safety performance, which continues to be world class and industry leading.

• |  | Outstanding environmental and regulatory compliance results, sustainability initiatives, and cybersecurity protections.

• |  | Continuing achievement of excellent management of working capital.

• |  | The successful organic and inorganic growth of Martin Marietta.

These resulted in strong payouts in response to the Company’s strong performance in 2020 – our pay-for-performance aligns our performance with management’s pay and with shareholders’ interests.

We also wanted to ensure that our Company and business model were resilient and robust enough to survive and thrive under all challenging circumstances, regardless of whether they are predictable or within management’s control. In this regard, the Committee developed a Resilience Scorecard that includes the key criteria described in the chart below that in our view measure our company’s ability to remain strong through severe, unexpected circumstances, as well as assessing management’s actions and whether they were appropriate in responding to and managing through events such as the pandemic. The Resilience Scorecard allows the Committee to apply a multiplier of 0.75x to 1.25x to management’s annual award that would be otherwise based on pre-event factors. These qualitative factors are important to position the Company to minimize the adverse impact of the pandemic and rebound quickly as the event subsides and the economy strengthens. We believe this scorecard is valuable to us under all circumstances, and not just to a pandemic. In the case of the pandemic’s impact on the Company’s performance in 2020, the Committee determined not to apply any multiplier in the Resilience Scorecard to management’s executive compensation for 2020. Further, the Committee made no COVID-19-related adjustments to our compensation based on the scorecard.

Category |  | Resilience Assessment Criteria
1. Employees |  | •Act effectively to keep employees safe and productive through enhanced equipment and faculty cleaning protocols, robust distancing and monitoring, and remote working •Effectively and promptly communicate and manage guidance and instructions, to employees through the newly-formed Martin Marietta Health Hub •Provide financial support and emotional care to employees •Offer opportunities for continued employee growth and development
2. Operations |  | •Ensure continuity of critical products and services •Minimize supply chain disruptions •Effectively and nimbly manage schedules and budgets for major capital projects (operations, IT systems, etc.) •Take steps to appropriately manage fixed and variables costs

The Committee also took into consideration that as an “essential business” under state and local laws, the Company’s operations remained open throughout the pandemic, as well as management’s response to the COVID-19 global pandemic, which included ensuring the health of our employees while continuing operations with minimal disruptions and continuing to serve our customers. After considering the Company’s achievements in 2020 with respect to the criteria outlined in the Resilience Scorecard, the Committee determined that it would not apply any adjustment to the annual incentive awards.

PAY DECISIONS AND COMPENSATION GOVERNANCE PRACTICES ◆ COMPENSATION DISCUSSION AND ANALYSIS

Pay Decisions and Compensation Governance Practices

A number of key 2020 compensation-related decisions resulted from our achievements, which are discussed more fully in this section. The Committee believes that our executive compensation program continues to reflect a strong pay-for-performance philosophy and is well aligned with the interests of shareholders. In addition, we believe that our compensation practices are consistent with our pay decisions.

WHAT WE DO |  | YES…
Pay for performance |  | Tie pay to performance by ensuring that a significant portion of NEO compensation is performance-based and at-risk.
Median compensation targets |  | We generally aim to align all compensation elements for our executives with the median of our peer group companies.
PSUs are a substantial portion of LTI |  | PSU grants, tied to our achievement of specified performance measures, comprised approximately 55% of the total value of annual long-term incentive grants made to our NEOs in 2020. Performance-based RSUs comprised the remaining 45%.
Independent compensation consultant |  | The Committee retains an independent compensation consultant.
Robust share ownership requirements |  | We have robust stock ownership guidelines of 7 times base salary for the CEO, 5 times base salary for our other NEOs, and 5 times annual retainer for Directors. We also have an equity retention requirement of 50% of net shares paid as incentive compensation until ownership guidelines are met.
Clawback policy |  | We have a compensation recovery (clawback) policy that requires officers to forfeit certain cash-based incentive compensation and/or equity-based incentive compensation if the company restates its financial statements due to the officer’s misconduct.
Regular engagement with shareholders |  | We engage with shareholders to hear their views on compensation and other issues.
Annual elections |  | All of our Directors stand for election each year.

WHAT WE DON’T DO |  | NO…
No employment contracts |  | None of our NEOs or other executive officers have employment contracts that guarantee continued employment.
No dividends on unvested awards |  | Our 2020 RSU and PSU awards require three years to fully vest and dividends paid on shares of common stock of Martin Marietta during the vesting period are only paid to award holders if and when an award vests.
No pledging of shares |  | Our directors and executive officers are not permitted to pledge Martin Marietta shares as collateral for loans or any other purpose.
No hedging |  | We prohibit directors and executive officers from engaging in short sales of Martin Marietta stock or similar transactions intended to hedge or offset the market value of Martin Marietta stock owned by them.
No 280G gross-ups |  | We do not provide executives with Section 280G excise tax gross-ups.
Minimal executive perquisites |  | We do not provide NEOs with country club reimbursements, personal use of the Company aircraft unrelated to business travel, or other excessive perks.

COMPENSATION DISCUSSION AND ANALYSIS ◆ DETERMINATION OF CEO COMPENSATION

Determination of CEO Compensation

At each February Committee meeting, without the CEO present, the Committee reviews and evaluates CEO performance, and determines achievement levels for the prior year. At this meeting, the Committee also discusses an evaluation of the CEO’s performance, competitive compensation data, and salary and annual incentive pay recommendations with the independent members of the Board. In addition, the Committee reviews and discusses an award of RSUs and the target PSU grant size for the CEO at that meeting, which is also discussed with the independent members of the Board. The Committee’s independent compensation consultant provides the Committee with comparative compensation, background materials and analysis, and its recommendation in connection with these determinations.

CEO Target Opportunity Mix*

* | We consider base salary and annual incentives as short-term pay and PSUs and RSUs as long-term pay. We do not include retirement or other compensation components in the chart.

2020 Chairman, President and CEO Compensation

Base Salary

For 2020, Mr. Nye’s base salary was set at $1,225,000 (effective March 1, 2020).

2020 Annual Incentive

Mr. Nye’s target annual incentive amount for 2020 was $1,697,500 (140% of salary received for the year). His actual annual incentive for 2020 was $3,300,000, or 194% of target.

2020-2022 Long-Term Incentives

In 2020, Mr. Nye’s target LTI award was 490% of base salary. He was granted an LTI award of approximately $6.0 million, which was allocated 55%, or $3.3 million, in PSUs and 45%, or $2.7 million, in performance-based RSUs. RSUs will vest pro rata over three years if the performance measure is satisfied, while the vesting of PSUs will be based upon our results relative to the three-year performance goals that were established in the beginning of 2020.

Benefit and Retirement Plans

Mr. Nye is eligible for benefit and retirement programs similar to other employees. None of our executives received additional years of service credits or other forms of formula enhancements under our benefit or retirement plans. Our pension formula is based on years of service and pension eligible compensation, which is a similar formula offered by other companies with defined benefit plans. Mr. Nye is not eligible for retiree health benefits.

Perquisites

Mr. Nye received limited executive perquisites. We provide company-leased cars to the NEOs for their use. Additionally, we pay for the insurance, maintenance and fuel for such vehicles. The value of personal mileage is charged to the NEO as imputed income. We make the company-owned aircraft available to the CEO and other senior executives for business travel only. We do not provide other perquisites, such as country club memberships, to the NEOs. The Committee reviews our policies and determines whether and to what extent perquisites should be modified or continued.

2020 Target Pay Mix

We believe that most of the compensation opportunities to our CEO should be variable and the variable elements of the compensation package should tie to the Company’s long-term success and the achievement of sustainable long-term total return to our shareholders. A significant portion of our CEO’s target compensation is variable and in the form of LTI, and more than half of total target pay is in the form of equity incentives.

2020 NAMED EXECUTIVE OFFICERS’ COMPENSATION—OUR COMPENSATION STRATEGY ◆ COMPENSATION DISCUSSION AND ANALYSIS

2020 Named Executive Officers’ Compensation – Our Compensation Strategy

Our executive compensation program is specifically designed to:

• |  | Attract and retain top-caliber, knowledgeable and experienced senior executives.

• |  | Motivate our executives to achieve superior results and build long-term value for shareholders.

• |  | Reward performance that meets or exceeds established goals consistent with our strategic aims and upholding integrity.

• |  | Align individual objectives with the Company’s objectives without fostering excessive or inappropriate risk-taking.

• |  | Encourage an ownership mentality and align the long-term financial interests of our executives with those of our shareholders.

• |  | Be market competitive with our peers with whom we compete for talent.

• |  | Provide reward systems that are measurable and easily understood by our executives and shareholders.

• |  | Inspire exceptional management and resiliency in times of unexpected and extraordinary circumstances.

• |  | Reinforce the succession planning process undertaken on a company-wide basis by building bench strength and by identifying and retaining senior leadership capable of achieving the Company’s long-term growth, profitability and other objectives.

In 2020, our executive compensation structure consisted of three primary components: base salary, annual incentives, and long-term incentives. Within the long-term incentive component, we utilized a balanced portfolio of PSUs and performance-based RSUs.

Martin Marietta has a long-standing commitment to pay for performance. We fulfill that aim by providing a majority of compensation through programs in which the amounts ultimately received vary in order to best reflect our financial, operational and strategic performance.

Pay Component |  | Summary
Base Salary |  | •At the February 2020 meeting, the Committee reviewed competitive market data and individual performance evaluations. Increases were effective March 1, 2020 for all NEOs.
Target Annual Cash Incentives |  | •Our CEO’s target incentive for 2020 was 140% of base earnings. For other NEOs’ target incentives for 2020 were 70% to 80% of base earnings. •Our shareholders in 2016 approved an Executive Cash Incentive Plan that fixed the bonus amounts based on certain objective criteria and allowed the Committee to reduce the award based on enumerated factors in the plan. •Our CEO is required to invest a minimum of 35% of his annual cash bonus into stock units, which are required to be held generally for a period of three years. •Other NEOs are required to invest a minimum of 20% of their annual cash bonus into stock units, which are held generally for a period of three years.
Long-Term Incentives |  | •Our LTI structure consists of PSUs and performance-based RSUs. •The LTI awards for NEOs in 2020 were weighted 55% PSUs and 45% RSUs. The LTI grant size is based on competitive market data. •PSU awards in 2020 are earned based on achievement of performance levels, with 33% based on three-year cumulative Sales Growth and 67% based on three-year cumulative adjusted EBITDA performance. The Company’s relative TSR ranking compared to the S&P 500 provides a modifier to the award up to 20%. •RSU awards to NEOs in 2020 are subject to the achievement of one-year adjusted EBITDA performance.
Total Compensation |  | •The Committee uses the size-adjusted 50th percentile of our Compensation Peer Group as a guide in setting the target for the total compensation opportunity, but considers a variety of factors in setting compensation, including the short-term and longer-term performance and leadership characteristics of the executive, and may vary materially. Overall, the Committee believes targeted compensation should be more heavily weighted on variable “at-risk” compensation and longer-term components.

The committee approved the following actual compensation items in February 2020:

2020 Base Salary

The Committee determines base salaries for the NEOs and other executives based on a number of factors, including but not limited to, market data, individual performance, the Company’s performance, internal pay equity, the advice of the Committee’s independent compensation consultant, management recommendations (except for the CEO), and, for the CEO, the Committee’s assessment of Mr. Nye’s performance. Based on these factors, the Committee approved the following increases in base salary.

• |  | Mr. Nye: 6.52% increase, based on his excellent achievements during his CEO tenure, and specifically his performance in 2019.

• |  | Other NEOs: approximately 3.4% to 7.6% increases, based on a review of competitive market data and individual performance evaluations.

NEO |  | 2020 Base Salary |  |  | 2019 Base Salary |
C. Howard Nye |  | $ | 1,225,000 |  |  | $ | 1,150,000 |
James A. J. Nickolas |  | $ | 565,000 |  |  | $ | 525,000 |

COMPENSATION DISCUSSION AND ANALYSIS ◆ 2020 ANNUAL CASH INCENTIVE GOALS AND RESULTS

2020 Annual Cash Incentive Goals and Results

NEOs and other executives are eligible to earn annual incentive compensation under our Executive Cash Incentive Plan based on the achievement of various performance metrics. Individual NEO targets (as a percent of base salary) are approved by the Committee at the beginning of the year based on a review of competitive market data, the advice of the Committee’s independent compensation consultant, and internal pay equity.

The Committee awards actual annual cash incentive compensation based on achievement against corporate performance objectives and individualized targeted goals. This furthers Martin Marietta’s compensation philosophy to encourage superior performance and reward the achievement of Martin Marietta’s annual goals. The Committee determined the 2020 incentive awards in February 2021. In 2020, all of the executive officers participated in the plan. The annual incentive compensation level paid for 2020 for the NEOs other than Mr. Nye was 190% to 210% of target. The annual incentive compensation level paid for 2020 for Mr. Nye was 194%.

In determining the incentive payment for the CEO, the Committee first reviews the achievements of Martin Marietta for the past year as compared to its targeted goals set at the end of the previous year. Our financial goals are established at the completion of our annual planning process, which for 2020 were determined in November 2019. The annual planning process includes reviews of the assumptions used by the business segments in generating their financial projections, such as industry trends and competitive assessments, current and future projected performance levels, and the risks and opportunities surrounding these baseline assumptions. The annual plan on which our financial goals are based is tied to the business environment in which we operate and can vary year-over-year.

Key individual performance criteria are established for each NEO, which are intended to drive strategic focus and support operational results in the Company and the functional groups. For the NEOs other than Mr. Nye, 50% of the determination is made with respect to Martin Marietta’s performance against the same goals as for Mr. Nye and 50% is based on the individual’s performance against established objectives.

The individualized target goals are tailored for each executive, based on his or her specific areas of responsibility and the then-current and longer-term goals of Martin Marietta. In addition, achievement of the goals typically is in part dependent on conditions outside the control of each of the NEOs. For example, our business may be adversely affected by hurricanes or other weather-related conditions, which could have the result of impeding the achievement of certain performance-based goals. Similar to the Committee’s assessment of financial goals, the Committee’s assessment of individual performance goals generally excludes non-recurring or extraordinary items.

The Committee also reviewed and considered management’s furtherance of its strategic plan, including a primary objective of value-enhancing growth, and the advancement of the Mission, Vision, and Values of the Company to unify management with the same objectives.

The Committee conducted a comparative review of the individual contributions of each of the executive officers towards achieving these goals. The Committee also considered qualitative measures of performance for the executive officers, such as adherence to and implementation of Martin Marietta’s Code of Ethical Business Conduct, customer satisfaction, and product quality.

The maximum incentive compensation is fixed based on objective criteria as described in the Executive Cash Incentive Plan, and the Committee then determines an appropriate award payout beneath the maximum amount based on the factors described above. We set challenging, but attainable, targets and our NEOs have a reasonable expectation of receiving cash incentive awards that reflect the achievement of our short- and long-term objectives as well as their individual performances.

2020 Actual Incentive Cash Earned

In 2020, the Committee determined that Company and individual performance warranted the annual incentive payments in the chart below based on a review of financial metrics and other important achievements. The Committee reviews the

NEOs’ performance based on continuous improvement from the preceding year. As described above, the Committee considered the following financial metrics in making this determination:

• |  | Pre-Tax Earnings (profitability) as against prior year and current year plan

• |  | EBITDA (profitability) as against prior year and current year plan

• |  | DSO (cash flow) as against prior year and current year plan

• |  | The factors outlined in the Resilience Scorecard, although the Committee did not adjust the award based on these factors

COMPENSATION DISCUSSION AND ANALYSIS ◆ ANNUAL INCENTIVE FEATURE: STOCK PURCHASE PLAN

Annual Incentive Feature: Stock Purchase Plan

The Incentive Stock Plan further promotes the alignment of executive compensation levels with our investors’ financial interests by requiring that a portion of the annual bonus award be deferred into Company stock units that vest based on continued service. Executive officers can also elect to defer amounts above the mandatory deferral amount. The voluntary election allows executives to invest up to 50% of their annual cash incentive compensation to purchase units that are subsequently converted into shares of common stock pursuant to the terms of the plan at a 20% discount from the market price of Martin Marietta’s common stock on the date the amount of the incentive compensation is determined. The discount is used to account for the risk of trading current cash compensation for “at-risk” shares which may decline in value.

The mandatory portion requires executives to invest a minimum of 20% of their cash incentive compensation towards the crediting of units under the plan. The CEO is required to invest a minimum of 35% of his cash incentive compensation towards the crediting of such units.

The units generally vest in three years from the date of the award and are distributed in shares of common stock. If an executive officer voluntarily terminates employment before the units vest, the stock units are forfeited and the executive officer receives a cash payment equal to the lesser of the cash that was invested or the fair value of the share units on the day of termination. Mr. Nye deferred the maximum of 50% of his 2020 cash bonus in stock units.

The mandatory contribution requirement directly links a portion of executive officer compensation to shareholder returns. The vesting aspect, combined with the yearly stock purchase requirement, creates continuous overlapping three-year cycles, which encourage executive officer retention and provide a continuous link of a significant portion of executive officer compensation with shareholder return over the long-term to reward these executive officers in line with our shareholders when our stock price increases.

2020 Long-Term Incentive Compensation Overview

Our LTI plan’s design reflects the objectives of our compensation program and is in-line with current market approaches, based on the advice of the Committee’s independent compensation consultant. Our plan design objectives are a simplified LTI program that is transparent and enhances the line of sight between our performance and compensation.

The award in 2020 for all NEOs was determined as a fixed percentage of base salary with some variation for position and grade, which amount was converted into common stock units based on the average Martin Marietta stock price for the 20-day period ending on February 19, 2020, the day the Martin Marietta Board of Directors confirmed the award, or $266.2545. This award value was then divided into PSUs and performance-based RSUs, with 55% of the total award for NEOs consisting of the PSUs at target level and 45% of the total award for NEOs consisting of performance-based RSUs. The Committee believes that the incentive mix (PSUs and performance-based RSUs) constitutes an appropriate pay process and streamlined plan, which more fully reflects the performance of the Company and is better aligned with each NEO’s role within Martin Marietta. See a further description under Outstanding Equity Awards at Fiscal Year-End and corresponding footnotes on page 68.

The following table provides a notional example of the LTI plan design.

Salary $ |  | LTI Target % |  | LTI Target Value $ |  | PSU % |  | PSU Value $ |  | RSU % |  | RSU Value $
$150,000 |  | 140% |  | $210,000 |  | 55% |  | $115,500 |  | 45% |  | $94,500

PSU Awards (55% of LTI Award)

One of our compensation objectives is to align the potential rewards to senior management with increases in shareholder value. In that regard, the PSUs give the recipient the opportunity to receive Martin Marietta common stock if specific performance goals are achieved, consisting of:

1) | Earnings before Interest, Income Taxes, Depreciation and Amortization (EBITDA), measuring profitability and comprising 67% of the total target award, and

54 2021 PROXY STATEMENT |  |  |  |

##### Table of Contents

PSU AWARDS (55% OF LTI AWARD) ◆ COMPENSATION DISCUSSION AND ANALYSIS

2) | Sales Growth, measuring growth and comprising 33% of the total target award.

3) | In addition, relative Total Shareholder Return (rTSR) will act as a modifier for the performance such that Martin Marietta’s performance will be measured against the S&P 500, and will modify the total award by a range of -20% to +20%.

The following table summarizes the weighting of our PSU performance measures:

Cumulative EBITDA |  | Cumulative Sales Growth |  | Relative TSR Modifier
67% |  | 33% |  | +/-20%

EBITDA and Sales Growth are two of the drivers of our performance and metrics of significance to our investors. The total payout opportunity for PSUs in 2020 was 0% to 240%: 50% of target if the threshold level is satisfied, 100% of target if the target level is satisfied, and 200% of target if the maximum level is satisfied. The rTSR modifier over the three-year measurement period is then applied to the final award to adjust it up or down by up to 20%. The threshold must be satisfied to receive PSUs for each performance metric. If the threshold is not met, none of the PSUs relating to that metric will vest.

Performance for each metric is measured independently, so PSUs can be earned as long as the threshold is satisfied for at least one metric. The “Target” level is generally viewed as achievable although it has not been achieved every year. The “Maximum” level is a stretch that is attainable if we outperform in the area measured. PSU payments are capped at the target level if three-year TSR is negative.

The performance will be measured in February 2023 for the three-year period beginning January 2020 through December 2022 to determine (1) the three-year cumulative EBITDA for Martin Marietta against the target identified in the PSU Award Agreement, and (2) the three-year cumulative Sales Growth against the target identified in the PSU Award Agreement. The payment amount will be further modified by the rTSR for the three-year period as against the S&P 500, as set forth in the PSU Award Agreement. The Committee in its discretion may adjust the final award values only as set forth in the Agreement, either collectively or on an individual basis, in recognition of factors that are unusual or nonrecurring.

Over the three-year performance period, up to one-third of the target PSUs may be earned each year based on one-third of the three-year cumulative EBITDA and Sales Growth goals. Each year, any earned PSUs are not distributed until the end of the three-year measurement period when the cumulative three-year performance is determined. The actual PSUs will equal the greater of the total PSUs earned for each of the annual periods (capped at 100% of the annual target, that is, one-third of the cumulative target) or the amount earned for cumulative three-year performance (capped at 200% of target). The final amount of earned PSUs to be distributed is then subject to the three-year rTSR modifier.

The PSUs will convert to unrestricted common stock and be distributed conditioned upon and to the extent that the performance goals have been met, which will be determined in February 2023. These awards are also generally subject to continued employment through the date the PSUs vest. The actual financial performance targets and achievement against those targets will be disclosed at the end of the three-year performance period.

Selection of Relative TSR

We selected rTSR for the PSUs to measure our performance against the companies in the S&P 500 index. We recognize that every industry faces different challenges and opportunities, and that the S&P 500 index does not perfectly correlate to the environment in which Martin Marietta operates. However, we believe that the majority of our closest competitors are not publicly-held companies or are not U.S. companies, and therefore accurate information to potentially use as comparisons is not readily available. As a result, we believe that comparing our TSR against the S&P 500 index is appropriate because (1) it measures the interest of investors for whom we compete, (2) there is no consensus of a significantly better peer group with readily available comparable financial information; and (3) by using rTSR as a modifier rather than a primary measurement, we give our other performance measures more weight and their focus on profitability and growth both provide long-term value creation.

##### Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS ◆ SELECTION OF RELATIVE TSR

We believe that EBITDA, Sales Growth and rTSR metrics drive the behaviors of our management team in ways that are intended to create the most value for our shareholders.

Performance-Based RSU Awards (45% of LTI Award)

RSUs vest in three equal portions, each on the anniversary of the grant date (February 19, 2020) over a period of three years, subject to satisfaction of the performance measure and generally to continued employment through each one of those anniversaries. Once the restricted period ends (each anniversary for one third of the total RSU award), the recipient will be issued unrestricted shares of common stock (minus applicable taxes). The 2020 RSUs awarded to executive officers are also subject to a performance measure that a stated level of EBITDA be achieved during the first year. If the performance measure is satisfied, then the RSUs will continue to vest. If the performance measure is not satisfied, then the RSUs will be forfeited. For the 2020 grants, the performance measure was satisfied.

2020-2022 Performance Goals

In setting minimum and maximum levels of payment, we reviewed historical levels of performance against our long-range plan commitments and conducted sensitivity analyses on alternative outcomes focused on identifying likely minimum and maximum boundary performance levels. Levels between 100% and the minimum and maximum levels were derived using linear interpolation between the performance hurdles.

The specific EBITDA and Sales Growth target values for the 2020-2022 PSUs are not publicly disclosed at the time of grant due to the proprietary nature and competitive sensitivity of the information. However, the method used to calculate the awards will be based on actual performance compared to our 2020-2022 targets, with straight-line interpolation between points. The individual award agreements require the adjustment of goals to ensure that the ultimate payouts are not impacted to the benefit or detriment of management by specified events, such as unplanned pension contributions, changes in accounting (GAAP) standards or impact of an acquisition or divestiture. The Committee may exercise its discretion to reduce the final vesting percentage to no more than target if the Company’s three-year TSR is less than zero.

The following table provides a summary of the long-term incentives that each of the NEOs was granted in 2020.

NEO |  | RSUs (3 year annual installment vesting subject to achievement of performance measure) (# of shares) |  | PSUs – Target (3 year cliff vesting subject to achievement of performance measures) (# of shares)
C. Howard Nye |  |  |  | 10,141 |  |  |  |  | 11,804 |
James A. J. Nickolas |  |  |  | 1,672 |  |  |  |  | 1,946 |

Daniel L. Grant |  |  |  | 901 |  |  |  |  | 1,049 |

In setting performance goals for the three-year PSUs awarded in 2020, the Committee considered various factors in choosing the metrics and establishing the goals, including:

• |  | The metrics reflect drivers of our performance and we believe are important to our investors.

• |  | The goals are consistent with our business plan and positive over prior year.

• |  | We have a history of setting challenging target and maximum goals.

In addition, we have looked at the alignment of our payouts with the Company’s performance, including TSR, and found that pay and performance are aligned.

2018-2020 PSU Award Payouts

PSUs that were granted in 2018 vested on December 31, 2020, because the applicable performance criteria were satisfied. These PSUs were certified and paid out in February 2021. The PSU payouts for the three-year performance period ended December 31, 2020 were calculated by comparing actual corporate performance for each metric for the period January 1, 2018 through December 31, 2020, against a table of payment levels from 0% to 200% (with the 100% payout level being considered target) established at the beginning of the performance period.

For the three-year performance period ended December 31, 2020, actual results were 200% of target. The results were above targeted level for each metric. EBITDA (weighted 67%) was $3.78 billion compared to our pre-established target of $3.24 billion and generated a 200% payout factor and Sales Growth (weighted 33%) was 13.92% compared to our pre-established target of 4.50% and generated a 200% payout factor. The rTSR modifier, which provides for an adjustment up or down of up to 20%, resulted in a 100.4% adjustment as our TSR over the three-year measurement period was at the 51st percentile of S&P 500 companies over the same period. The awards are calculated pursuant to the provisions provided in the award agreements. The Committee cannot make any adjustments to the final payout factor beyond the adjustments specified in the award agreements.

Ongoing Corporate Governance Policies

We endeavor to maintain good corporate governance standards relating to our executive compensation policies and practices, including the following that were in effect during 2020 that directly impacted compensation:

• |  | The Committee is comprised solely of independent Directors who regularly schedule and meet in executive sessions without management present.

• |  | The Committee’s independent compensation consultant is retained directly by the Committee.

• |  | The Committee conducts an annual review of and approves our compensation strategy, including a review of our compensation-related risk profile, to ensure that our compensation-related risks are not reasonably likely to have a material adverse effect on the Company.

• |  | We pay for performance, with approximately 87% of our CEO’s total target pay opportunity being performance-based “at-risk” compensation.

• |  | We cap PSU payments at target if three-year TSR is negative, regardless of our ranking.

• |  | We limit perquisites and other benefits.

Compensation Decision Process

Role of Management and the Committee

The Committee is responsible for carrying out the philosophy and objectives of the Board of Directors related to executive compensation in addition to its responsibilities of overseeing the development and succession of executive management of Martin Marietta. The Committee has the authority to determine compensation and benefits for Martin Marietta’s executive officers. The Committee members are each non-employee, independent Board members pursuant to the NYSE rules, and the Committee operates pursuant to a written charter, a copy of which can be viewed on Martin Marietta’s website at ir.martinmarietta.com/corporate-governance.

The performance of the CEO and each other executive officer is reviewed regularly by the Committee. Based on this review, the Committee sets compensation for all executive officers. Compensation decisions with respect to the executive officers other than the CEO are based in part on recommendations by the CEO, with input from the Senior Vice President and Chief Human Resource Officer, with respect to salary adjustments and annual cash and equity awards. The Committee can accept, reject or modify any recommended adjustments or awards to executive officers. For the CEO, the Committee sets the levels of annual adjustments and awards based on the criteria it deems to be appropriate under the circumstances with input from the independent compensation consultant. There are no employment agreements between Martin Marietta and any executive officer of Martin Marietta, including the CEO.

COMPENSATION DECISION PROCESS ◆ COMPENSATION DISCUSSION AND ANALYSIS

Role of the Independent Compensation Consultant

The Committee retained Pay Governance, an independent compensation consultant, in accordance with the Committee’s charter, in April 2020. Prior to April 2020, Mercer served as the Committee’s independent compensation consultant.

The consultant reports directly to the Committee. The Committee retains sole authority to hire or terminate the consultant, approve its compensation, determine the nature and scope of services, and evaluate performance. The compensation consultant attends Committee meetings, either in person or by telephone, as requested, and communicates with the Committee Chair between meetings. The Committee makes all final decisions.

The compensation consultant’s specific roles include, but are not limited to, the following:

• |  | Advise the Committee on executive compensation trends and regulatory developments and other factors affecting executive officer compensation, as well as any other areas of concern or risk.

• |  | Provide a total compensation assessment for executives compared to peer companies and recommendations for executive pay.

• |  | Serve as a resource to the Committee Chair for meeting agendas and supporting materials in advance of each meeting.

• |  | Review and comment on proxy disclosure items, including this CD&A.

• |  | Advise the Committee on management’s pay recommendations.

Based on these activities, the compensation consultant makes recommendations regarding, and proposes adjustments to, our executive officer compensation program as it deems appropriate. While the consultant works closely with the appropriate members of our executive management team in performing these activities, the consultant reports directly to and is retained by the Committee on all executive compensation matters, and speaks to the Committee and the Chair of the Committee on a regular basis without management present.

Role of Peer Companies and Competitive Market Data

The Committee considered peer groups for two elements of the executive compensation program in 2020: the Compensation Peer Group, consisting of 15 companies that the Committee believes compete with us for talent, and the TSR Peer Group, consisting of the S&P 500, which the Committee believes compete with us for investors and is used to assess the achievement of rTSR measured for the PSU awards.

Annually, the Committee studies competitive total compensation market data provided by its independent compensation consultant. To assess competitive pay levels, the Committee reviews and approves the composition of our Compensation Peer Group. The following peer group criteria are considered:

• |  | Company size (approximately 0.4 times to 2.5 times Martin Marietta’s annual revenues);

COMPENSATION DISCUSSION AND ANALYSIS ◆ COMPENSATION DECISION PROCESS

The Committee studies competitive total compensation data from various sources, including proxy statements of the peer group. Since proxy statements do not provide precise comparisons by position to our executive officers, in 2020 the Committee also took into consideration published independent compensation surveys of companies with revenue in the range of $2.5 billion to $8.0 billion as to median levels for each executive officer as well as private compensation survey data. Where available, size-adjusted market values were developed using regression analysis. This statistical technique accounts for revenue size differences within the peer group and develops an estimated market value for a similar-size company as Martin Marietta. The size-adjusted 50th percentile for total compensation is a key reference point for the Committee. On average, the target for our NEO total compensation opportunities is competitively positioned within a reasonable range of the size-adjusted 50th percentile.

Although the Committee uses the size-adjusted 50th percentile as its starting point in setting compensation levels, the compensation packages for executive officers may vary materially from it based on several factors. Market data, position, tenure, individual and organization performance, retention needs and internal pay equity have been the primary factors considered in decisions to increase or decrease compensation opportunities. Specifically, the Committee typically sets compensation levels below the size-adjusted 50th percentile for executive officers with relatively less relevant experience, less responsibility, less tenure with Martin Marietta and/or lower performance ratings. Conversely, if an officer consistently receives favorable performance ratings, accumulates years of service and expertise in relevant areas, has more responsibility and/or has significant other achievements, his or her compensation will typically be above the size-adjusted 50th percentile.

Other Compensation Program Features

Compensation Program Risk Assessment

We perform a thorough annual review of our compensation program structure and all compensation programs, which are also reviewed in detail with the Committee. We believe our executive pay is appropriate and provides necessary incentives to our executives to achieve our financial and strategic goals without encouraging them to take excessive risks in their business decisions. Our compensation structure does not include features that are reasonably likely to have a material adverse effect on the Company. Compensation program features that mitigate against risks include the following:

• |  | Our annual incentive compensation plan does not provide payment for poor individual or corporate performance, regardless of whether the failure to achieve target was outside management’s control.

• |  | There are caps on the long-term equity awards, even if the required performance-related criteria are exceeded.

• |  | A majority of the NEOs’ compensation is long-term, with equity grants vesting over three to five years, depending on the award.

• |  | Our compensation is not based on highly leveraged short-term incentives that encourage high risk investments at the expense of long-term value.

• |  | Long-term compensation to executive officers is based on specific performance measures that balance long-term growth and returns.

• |  | The Committee uses benchmarking data and the advice of its independent compensation consultant to keep compensation in line with typical market practices and appropriate to Martin Marietta’s needs.

• |  | We use a balanced portfolio of long-term incentive programs.

• |  | The Committee’s governance process requires review and approval of all compensation over a certain amount.

Stock-Based Awards Generally

All of Martin Marietta’s active equity-based award plans have been approved by shareholders. Our Stock Plan requires a minimum vesting period of 12 months for restricted stock or RSUs and a minimum vesting period of 36 months for stock options or stock appreciation rights (SARs). The Company has not issued SARs and has not issued stock options since 2015.

STOCK OWNERSHIP REQUIREMENTS ◆ COMPENSATION DISCUSSION AND ANALYSIS

Stock Ownership Requirements

In 2018, the Board adopted robust formal Stock Ownership Guidelines for executive officers and members of the Board of Directors. These require the following ownership levels as a multiple of base salary or annual cash retainer, as applicable:

Title |  | Annual Base Salary Multiple
Chairman, President and CEO |  | 7 times
Other Executive Officers |  | 5 times
Other Members of the Board of Directors |  | 5 times

The following types of equity instruments count in determining stock ownership for purposes of these guidelines:

• |  | Shares owned separately by the covered person or owned either jointly with, or separately by, his or her immediate family members residing in the same household;

• |  | Shares held in trust for the benefit of the covered person or his or her immediate family members;

• |  | Shares purchased on the open market;

• |  | Shares obtained through stock option exercise (and not thereafter sold);

• |  | Vested shares pursuant to RSUs;

• |  | Unvested RSUs;

• |  | Shares held pursuant to deferred stock unit plans for Directors or executive officers; and

• |  | Shares acquired under the Company’s Savings and Investment Plan and similar plans or arrangements

Covered persons who are employees are expected to meet these requirements within five years of the later of becoming a covered person and the date of adoption of the policy. Until such time as such covered person has met these requirements, he or she is expected to retain 50% of any shares of common stock received upon vesting of RSUs, deferred stock unit awards, PSUs, the exercise of stock options, and other similar equity awards, net of amounts withheld to pay taxes and the exercise price of stock options until the applicable Guideline level is met.

Stock ownership does not include vested or unvested stock options, unvested PSUs and vested or unvested stock appreciation rights.

All of the Company’s executive officers and members of the Board of Directors are in compliance with the Stock Ownership Guidelines.

We also require a holding period of annual cash incentive compensation converted to Martin Marietta share equivalents as described below, with vesting generally in three years. There is no additional holding period beyond the vesting date, however a significant portion of the executive compensation program is in the form of equity awards that vest over three years generally.

Our CEO must invest a minimum of 35% of each year’s cash bonus award in common stock units of Martin Marietta. Executive officers must invest a minimum of 20% of their annual bonus. Stock is purchased at a 20% discount to the price on the grant date to account for the additional risk of taking a common stock unit payment in lieu of a risk-free cash payment. In 2020, Mr. Nye deferred the maximum of 50% of his cash bonus in common stock units.

Anti-Hedging and Pledging Policy

Our policies prohibit hedging and pledging of Martin Marietta stock by all directors and executive officers. Under our policies, directors and executive officers may not engage in any hedging or monetization transactions, such as puts, calls, options, other derivative securities, prepaid variable forward contracts, equity swaps, collars, exchange funds and short sales with respect to Company stock, the purpose of which is to hedge or offset any decrease in the market value of such stock. This policy also prohibits Directors and executive officers from purchasing Company stock on margin, borrowing against Company stock on margin, or pledging Company stock as collateral for any loan.

COMPENSATION DISCUSSION AND ANALYSIS ◆ CLAWBACK POLICY

Clawback Policy

We also have a clawback policy. If the Board determines that an officer’s intentional misconduct, gross negligence or failure to report such acts by another person was a contributing factor in requiring us to restate any of our financial statements or constituted fraud, bribery or another illegal act (or contributed to another person’s fraud, bribery or other illegal act) which adversely impacted our financial position or reputation, then the Board shall take such action as it deems in the best interest of the Company and necessary to remedy the misconduct and prevent its recurrence. Among other actions, the Board may seek to recover or require reimbursement of any amount awarded to the officer in the form of an annual incentive bonus or LTI award. There were no events requiring Board consideration of a clawback action during 2020.

Our Use of Independent Compensation Consultants

The independent compensation consultant provides important information about market practices, the types and amounts of compensation offered to executives generally and the role of corporate governance considerations in making compensation decisions. The Committee’s charter authorizes it to retain outside advisors that it believes are appropriate to assist in evaluating executive compensation.

In April 2020, the Committee retained Pay Governance as a new independent compensation consultant. Prior to this change, Mercer served as the Committee’s independent compensation consultant.

In connection with its retention of Pay Governance, the Committee considered the following factors in assessing Pay Governance independence:

• |  | The provision of services provided by Pay Governance to Martin Marietta in addition to compensation advisory services.

• |  | The compensation paid to Pay Governance is less than 1% of Pay Governance’s revenues.

• |  | Pay Governance has business ethics and insider trading and stock ownership policies, which are designed to avoid conflicts of interest.

• |  | Pay Governance employees supporting the engagement do not own Martin Marietta securities.

• |  | Pay Governance employees supporting the engagement have no business or personal relationships with members of the Compensation Committee or with any Martin Marietta executive officer.

At a special meeting in April 2020, the Committee discussed the engagement of Pay Governance. At that time, Pay Governance confirmed the validity of each of the factors described above.

The nature and scope of Pay Governance engagement was determined by the Committee and not limited in any way by management. The Committee also considered Pay Governance Global Business Standards intended to address potential conflicts of interests with respect to their executive compensation consulting services and the other factors required to be considered by applicable SEC and NYSE rules in approving the Committee’s engagement of Pay Governance for 2020. Based on this review, the Committee did not identify that Pay Governance had any conflicts of interest that would prevent Pay Governance from independently advising the Committee. Pay Governance did not provide any additional services beyond those relating to director and executive officer compensation in an amount in excess of $120,000 in 2020.

For the period from January 1, 2020 to April 7, 2020, the Committee paid Mercer, its former executive compensation consultant, $77,768 for its compensation advisory services. During 2020, Mercer and its Marsh & McLennan affiliates were also retained by management to provide services unrelated to executive compensation, including property/casualty insurance brokerage services and administration of a risk management information system. The aggregate fees paid for those other services for 2020 were $295,198. The Committee and the Board did not review or approve the other services provided to us by Mercer and its Marsh & McLennan affiliates as those services are approved by management in the normal course of business.

We were advised by Mercer that the reporting relationship and compensation of the individual Mercer consultants who performed executive compensation consulting services for our Committee were separate from, and were not determined by reference to, Mercer’s or Marsh & McLennan’s other lines of business or their other work for us. The Committee

62 2021 PROXY STATEMENT |  |  |  |

##### Table of Contents

PRACTICE REGARDING TIMING OF EQUITY GRANTS ◆ COMPENSATION DISCUSSION AND ANALYSIS

considered these separate reporting relationships and compensation structures, the provision of other services to the Company by Mercer and Marsh & McLennan (including in prior years), and the absence of any business or personal relationship between our officers and Directors and the specific Mercer consultants advising the Company (other than the consulting relationship with the Committee). The Committee also considered Mercer’s Global Business Standards intended to address potential conflicts of interests with respect to their executive compensation consulting services and the other factors required to be considered by applicable SEC and NYSE rules in approving the Committee’s engagement of Mercer for the portion of 2020. Based on this review, the Committee did not identify that Mercer had any conflicts of interest that would prevent Mercer from independently advising the Committee during the term of its engagement in 2020.

Practice Regarding Timing of Equity Grants

The stock purchase awards under our Incentive Stock Plan and the PSUs and RSUs awarded under our LTI program, each as described above, were granted in 2020 at the Committee’s regularly scheduled meetings in February following the availability of financial results for the prior year. Newly hired executive officers may, subject to the discretion of the Committee, receive an award of RSUs as of the date of their hire. The number of such RSUs is based on the NYSE closing price of Martin Marietta’s common stock on the date of the grant or the first date of employment, whichever is later. The Committee’s schedule is determined several months in advance and the proximity of any awards to earnings announcements or other market events is coincidental.

Our practice with regard to the timing of equity grants is:

• |  | No equity award may be backdated. A future date may be used if, among other reasons, the Committee’s action occurs in connection with a new employee who has not yet commenced employment.

• |  | Proposed equity awards are presented to the Committee in February of each year. Off-cycle awards may be considered in the Committee’s discretion in special circumstances, which may include hiring, retention or acquisition transactions.

In addition, our existing stock award plan prohibits repricing of stock options or paying cash for underwater stock options.

Perquisites

Martin Marietta provides executives with perquisites that the Committee believes are appropriate, reasonable and consistent with its overall compensation program to better enable Martin Marietta to attract and retain superior employees for key positions. The Committee periodically reviews the types and levels of perquisites provided to the NEOs. The value of each of the NEO’s perquisites, determined in accordance with SEC rules, is included in the annual compensation set forth in the Summary Compensation Table.

In 2020, we provided personal use of leased automobiles to NEOs. We pay for the insurance, maintenance and fuel for such vehicles, and the value of personal mileage and use is charged to the NEO as imputed income. We make the company-owned aircraft available to the CEO and other senior executives for business travel. If the NEO is accompanied by his or her spouse on such trips, that use is included in the NEO’s taxable income for the year and the incremental cost, if any, is included as “All Other Compensation” in the Summary Compensation Table required to be included in our Proxy Statement for that year.

Martin Marietta also provides to executive officers, as well as most other salaried employees, certain other fringe benefits such as tuition reimbursement, airline club dues, professional society dues, and food and recreational fees incidental to official company functions. We do not provide other perquisites, such as country club memberships or financial planning services, to the NEOs or other employees.

Retirement and Other Benefits

In order to maintain market competitive levels of compensation, we provide retirement and other benefits to the NEOs and other employees, including:

• |  | Medical and dental benefits

• |  | Life, accidental death and disability insurance

• |  | Pension and savings plans

|  |  |  | MARTIN MARIETTA 63

##### Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS ◆ POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

The benefits under the defined benefit pension plan are more valuable for employees who remain with Martin Marietta for longer periods, thereby furthering our objectives of retaining individuals with more expertise in relevant areas and who can also participate in management development for purposes of executive succession planning. All of Martin Marietta’s salaried employees in the United States are eligible to participate in our retirement and other plans, and the NEOs participate in the plans on the same terms as Martin Marietta’s other salaried employees.

Additional information regarding these benefits is under the heading Pension Benefits Table on page 71 and the accompanying narrative.

Potential Payments upon Termination or Change of Control

We do not have written employment agreements with executives. Instead, each of our NEOs has a change of control severance agreement (an Employment Protection Agreement) that provides for retention and continuity in order to minimize disruptions during a pending or anticipated change of control. The agreements are triggered only by a qualifying termination of employment in connection with a change of control. Martin Marietta’s equity-based award plans and retirement plans also provide for certain post-termination payments and benefits, as well as, for equity awards granted prior to 2020, the acceleration of time periods for purposes of vesting in, or realizing gain from, such equity award in the event of a change of control. The Committee believes these payments and benefits are also important to align the interests of the executive officers with the interests of the shareholders because the agreements will reduce or eliminate the reluctance to pursue potential change of control transactions that may ultimately lead to termination of their employment but would otherwise be in the best interests of our shareholders. The Employment Protection Agreements are described on page 73 of this Proxy Statement.

Tax and Accounting Implications

In administering the compensation program for NEOs, for awards made in 2021 the Committee considered tax consequences, including the limit on deductibility on compensation in excess of $1 million to certain executive officers under Section 162(m) of the Internal Revenue Code and the consequences under financial accounting standards.

While the Committee considers the tax deductibility as one factor in determining executive compensation, the Committee also looks at other factors in making its decisions, as noted above, and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program to attract talent, promote retention, or recognize and reward desired performance even if the awards are not deductible for income tax purposes.

GRANTS OF PLAN-BASED AWARDS ◆ EXECUTIVE COMPENSATION

4 | The amounts shown in column (l) reflect the grant date fair value of each equity award computed in accordance with FASB ASC Topic 718. No options to purchase shares of Martin Marietta’s common stock were granted in 2020.

Stock-based incentive awards have been a significant component of Martin Marietta’s management compensation. In 1998, the Board of Directors adopted and Martin Marietta’s shareholders approved the Stock Plan. In 2016, the Board of Directors and the shareholders approved amendments to the plan increasing the number of shares of Martin Marietta’s common stock available for equity awards. They also approved amendments to the plan designed to more directly tie long-term compensation incentives to Martin Marietta’s performance and enhance flexibility in structuring long-term incentive compensation packages by providing a mix of different types of long-term stock-based incentives. In addition, dividend equivalents that would have been paid in cash during the vesting period will be paid only if and when an award vests.

As amended, the Stock Plan authorizes the Management Development and Compensation Committee to award stock options, restricted stock and other stock-based incentive awards to employees of Martin Marietta for the purpose of attracting, motivating, retaining and rewarding talented and experienced employees. Since 2016, Martin Marietta’s long-term compensation program consists of a mix of RSUs and PSUs for senior level employees and other select employees.

Vesting of the awards granted in 2020 is based on the achievement by Martin Marietta of performance measures described under “2020 Long-Term Incentive Compensation” on pages 54 to 58.

A maximum of 5,800,000 shares of Martin Marietta’s common stock are authorized under the plan for grants to key employees. Each award under the plan is evidenced by an award agreement setting forth the number and type of stock-based incentives subject to the award and such other terms and conditions applicable to the award as determined by the Committee. No employee may receive annual grants for more than 300,000 shares of common stock with respect to (i) full-value awards or (ii) stock options or stock appreciation rights.

Retirement and Other Benefits

In order to maintain market competitive levels of compensation, we provide retirement and other benefits to the named executive officers and other employees. The benefits under the defined benefit pension plan are more valuable for employees who remain with Martin Marietta for longer periods, thereby furthering Martin Marietta’s objectives of retaining individuals with more expertise in relevant areas and who can participate in management development for purposes of executive succession planning. All of Martin Marietta’s salaried employees in the United States are eligible to participate in the following retirement and other plans. The named executive officers participate in the plans on the same terms as Martin Marietta’s other salaried employees.

Pension Plan. We have a tax qualified defined benefit pension plan (Pension Plan) under which eligible full-time salaried employees of Martin Marietta who have completed five continuous years of employment with Martin Marietta, including the named executive officers, earn the right to receive certain benefits upon retirement on a reduced basis at or after age 55 and on an unreduced basis at or after age 62. Retirement benefits are monthly payments for life based on a multiple of the years of service and the final average eligible pay for the five highest consecutive years in the last ten years before retirement, less an offset for social security. The amount is equal to the sum of (A), (B) and (C) below:

(A) | 1.165% of the participant’s final average eligible pay up to social security covered compensation, multiplied by the participant’s credited years of service up to 35 years;

(B) | 1.50% of the participant’s final average eligible pay in excess of social security covered compensation, multiplied by the participant’s credited years of service up to 35 years; and

(C) | 1.50% of the participant’s final average eligible pay multiplied by the participant’s credited years of service in excess of 35 years.

EXECUTIVE COMPENSATION ◆ RETIREMENT AND OTHER BENEFITS

Supplemental Excess Retirement Plan (SERP). We also have a non-qualified restoration plan that covers any employee in the defined benefit pension plan, including the named executive officers, who are highly compensated and whose qualified plan benefit is reduced by Internal Revenue Code benefit or pay limits in Sections 415(b) and 401(a)(17). The plan is based on the same formula as the qualified Pension Plan described above. Benefits under our nonqualified plan are paid from our general assets.

Savings and Investment Plan. The Savings and Investment Plan is a tax-qualified defined contribution retirement savings plan pursuant to which all employees in the United States, including the named executive officers, are eligible to contribute up to 25% or the limit prescribed by the Internal Revenue Service on a ROTH individual retirement account on a before-tax basis and up to an additional 17% of pay on an after-tax basis not to exceed a total of 25% of pay. We match 100% of the first 1% of pay and 50% of the next 5% of pay that is contributed by employees to the Savings and Investment Plan up to Internal Revenue Service limitations. All contributions as well as any matching contributions are fully vested upon contribution. Prior to 2015, the Company sponsored two defined contribution savings plans, the Performance Sharing Plan for salaried employees and the Savings and Investment Plan for hourly employees generally. The two plans were merged in 2014.

Retiree Medical. Eligible salaried employees who commenced employment with Martin Marietta prior to December 1, 1999 and who retire with at least 5 years of service are currently eligible for retiree medical benefits until age 65 and then will receive a one-time payment of $1,000 upon reaching age 65 (or upon retirement, if after reaching age 65). Eligible salaried employees who commenced employment with Martin Marietta between December 1, 1999 and December 31, 2001 and who retire with at least 15 years of service are currently eligible for retiree medical benefits until age 65. Eligible employees share the cost of retiree medical based on their years of service and a predetermined cap on total payments by Martin Marietta. Employees who commenced employment with Martin Marietta on or after January 1, 2002 are not eligible for retiree medical benefits. Mr. Nye, Mr. Nickolas, Mr. LaTorre and Mr. Grant are not eligible for retiree medical benefits as each commenced employment with Martin Marietta after 2002.

Medical Insurance. Martin Marietta provides an opportunity to all of its salaried employees in the United States and the employees’ immediate family members to select health, dental and vision insurance coverage. Martin Marietta pays a portion of the premiums for this insurance for all employees. All employees in the United States, including the named executive officers, pay a portion of the premiums depending on the coverage they choose.

Life and Disability Insurance. Martin Marietta provides to all of its salaried employees in the United States, including the named executive officers, long-term disability and life insurance that provides up to 1.5 times base salary at no cost to the employee. All of our employees in the United States, including the named executive officers, can choose additional coverage and pay a portion of the premiums depending on the coverage they choose. In addition, Martin Marietta pays an amount equal to one year of base salary in the event of death of any active salaried employee.

Housing Allowance and Relocation Costs. Martin Marietta provides relocation benefits, including a housing allowance, to certain employees upon their employment with Martin Marietta or in conjunction with a job relocation or promotion.

Pension Benefits

The table below shows the present value of accumulated benefits payable to each of the named executive officers, including the number of years of service credited to each such named executive officer, under our Pension Plan and SERP, determined using interest rate and mortality rate assumptions consistent with those used in Martin Marietta’s financial statements.

The Pension Plan is a defined benefit plan sponsored by Martin Marietta and covers all of Martin Marietta’s executive officers, including the named executive officers, and substantially all of the salaried employees of Martin Marietta on a non-contributing basis. Compensation covered by the Pension Plan generally includes, but is not limited to, base salary, executive incentive compensation awards, lump sum payments in lieu of a salary increase, and overtime. The normal retirement age under the Pension Plan is 65, but unreduced early retirement benefits are available at age 62 and reduced benefits are available as early as age 55. The calculation of benefits under the Pension Plan is generally based on an annual accrual rate, average compensation for the highest consecutive five years of the ten years preceding retirement, and the participant’s number of years of credited service (1.165% of average compensation up to social security covered compensation for service up to 35 years and 1.50% of average compensation over social security covered compensation for service up to 35 years and 1.50% of average compensation for service over 35 years). Benefits payable under the Pension Plan are subject to current Internal Revenue Code limitations, including a limitation on the amount of annual compensation for purposes of calculating eligible remuneration for a participant under a qualified retirement plan ($285,000 in 2020). Martin Marietta’s SERP is a restoration plan that generally provides for the payment of benefits in excess of the Internal Revenue Code limits, which benefits vest in the same manner that benefits vest under the Pension Plan. The SERP provides for a lump sum payment of the vested benefits provided by the SERP subject to the provisions of Section 409A of the Internal Revenue Code. Of the named executive officers, Mr. Nye, Ms. Bar and Mr. Grant are each eligible for early retirement, which allows for payment to employees who are age 55 or older with at least five years of service at a reduced benefit based on the number of years of service and the number of years prior to age 62 at which the benefits began. Mr. Nickolas is not yet eligible for early retirement, but would be eligible for payments at age 55 at a reduced benefit based on the number of years of service and the number of years prior to age 65 at which the benefits began. Mr. LaTorre is not yet eligible for early retirement, but would be eligible for payments after 5 years of service at a reduced benefit based on the number of years of service and the number of years prior to age 65 at which the benefits began. The present value of the Pension Plan and SERP benefit, respectively, for Mr. Nye, Mr. Nickolas, Ms. Bar, Mr. LaTorre, and Mr. Grant, if they had terminated on December 31, 2020 and began collecting benefits at age 55 or current age if older would be as follows: Mr. Nye, $787,023 and $12,090,532, respectively; Mr. Nickolas, $0 and $0, respectively, since he has less than five years of service with Martin Marietta and therefore is not vested in the plans; Ms. Bar, $1,655,804 and $7,225,391, respectively; Mr. LaTorre, $0 and $0, respectively, since he has less than five years of service with Martin Marietta and therefore is not vested in the plans; and Mr. Grant, $387,130 and $896,012, respectively. The amounts listed in the foregoing table are not subject to any deduction for Social Security benefits or other offset amounts.

EXECUTIVE COMPENSATION ◆ POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

Potential Payments Upon Termination or Change of Control

The discussion and tables below reflect the amount of potential payments and benefits to each of the named executive officers at, following, or in connection with any termination of such executive’s employment, including voluntary termination, involuntary not-for-cause termination, for-cause termination, normal retirement, early retirement, in the event of disability or death of the executive, and termination following a change of control. The amounts assume that such termination was effective as of December 31, 2020 and thus includes amounts earned through such time and are estimates of the amounts that would have been paid out to the executives upon their termination at such time. The actual amounts to be paid out can only be determined at the time of such executive’s actual separation from Martin Marietta.

Payments Upon Any Termination. Regardless of the manner in which the employment of a named executive officer terminates, he or she is entitled to receive the amounts earned during the term of employment, including cash compensation earned during the fiscal year, amounts contributed by the employee and Martin Marietta’s matching contributions to the Savings and Investment Plan, unused earned vacation pay and amounts accrued and vested through Martin Marietta’s Pension Plan and SERP.

Payments Upon Voluntary Termination. In addition to the amounts described under the heading Payments Upon Any Termination, upon a voluntary termination of employment, the named executive officer would be entitled to receive the lower of the amount of cash contributed to the Incentive Stock Plan or the current market value of the common stock units credited to the employee measured by the NYSE closing price of Martin Marietta’s common stock on the date of termination.

Payments Upon Involuntary Not-For-Cause Termination. In addition to the amounts described under the heading Payments Upon Any Termination, upon an involuntary termination of employment not for cause, the named executive officer would be entitled to receive a prorated share of the common stock units credited to him or her under the Incentive Stock Plan paid out as shares of common stock and the remaining cash contribution invested by the employee in the plan.

Payments Upon Involuntary For-Cause Termination. In the event of involuntary termination for cause, which is defined in the Employment Protection Agreement and the Stock Plan, the named executive officer would be entitled to receive the payments and benefits described under the heading Payments Upon Voluntary Termination.

Payments Upon Retirement. In the event of the retirement at age 62 or above of a named executive officer, in addition to the items described under the heading Payments Upon Any Termination, the executive will receive a portion of the cash incentive bonus based upon performance and payable under the Executive Cash Incentive Plan that correlates to the percentage of the year in which the employee worked for the Company; will continue to hold all outstanding options unaffected by the retirement and retain such options for the remainder of the outstanding term; will continue to hold all awards of RSUs and PSUs for the remainder of the outstanding term unaffected by the retirement; will vest in all outstanding awards of common stock units under the Incentive Stock Plan; in the case of Ms. Bar, will be eligible to receive health and welfare benefits as described under the heading Retiree Medical on page 70; and will continue to receive life insurance coverage until his or her death.

Payments Made Upon Early Retirement. In the event of retirement prior to reaching age 62 but on or after reaching age 55, the named executive officer will receive benefits as described under the heading Payments Upon Voluntary Termination. In addition, the named executive officer will receive reduced benefits of the type described under Pension Benefits on pages 70 to 71 and may be eligible for benefits described under the heading Retiree Medical beginning on page 70 at a higher cost.

Payments Upon Death or Disability. In the event of the death or disability of a named executive officer, in addition to the payments and benefits under the heading Payments Upon Any Termination, the named executive officer or his or her estate will receive benefits under Martin Marietta’s long-term disability plan or life insurance plan, as applicable, and a death benefit payment, as applicable, equal to the then-current base salary of such employee paid under the Pension Plan plus one month base salary. In addition, in the event of death, all options will vest and the executor of their estate will have one year to exercise the options. In the event of disability, the executive will receive a portion of the cash incentive compensation based upon performance and payable under the Executive Cash Incentive Plan that correlates to the percentage of the year in which the employee worked for the Company; will continue to hold all outstanding options

unaffected by the disability and will retain such options for the remainder of the outstanding term; will continue to hold all awards of PSUs and RSUs for the remainder of the outstanding term unaffected by the disability; and will vest in all outstanding awards of common stock units under the Incentive Stock Plan.

Payments Upon or in Connection With a Change of Control. Martin Marietta has entered into Employment Protection Agreements, as amended from time to time, with each of the named executive officers. The purpose of these agreements is to provide Martin Marietta’s key executives with payments and benefits upon certain types of terminations within two years following a “Change of Control.” For purposes of the agreements, a Change of Control is generally defined as (i) the acquisition by any person, or related group of persons, of 40% or more of either the outstanding common stock of Martin Marietta or the combined voting power of Martin Marietta’s outstanding securities, (ii) consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of Martin Marietta’s assets following which Martin Marietta’s shareholders before such event fail to own more than 50% of the resulting entity, (iii) a change in the majority membership of the Board, or (iv) a liquidation or dissolution of Martin Marietta.

The agreements provide that if, within the two-year period following a Change of Control, an executive is terminated without “Cause” (as defined in the agreements) or terminates his or her employment with “Good Reason” (as defined in the agreements), Martin Marietta is obligated to pay the executive, in a lump sum, an amount equal to three times the sum of the executive’s base salary, annual bonus, and Martin Marietta’s match to the defined contribution plan; the payment of a pro-rata annual target bonus in the year of termination as determined under the Executive Cash Incentive Plan (for Mr. Nye such target bonus is 140% for purposes of the Employment Protection Agreement) and to provide continuation of health, medical and other insurance benefits for a period of three years following termination. The rationale for selecting these triggers is to encourage the named executive officers to remain focused on Martin Marietta, its performance and matters that are in the best interests of its shareholders rather than be distracted by the personal impact to their employment that the Change of Control may have. For purposes of the agreements, “base salary” means the highest annual rate of base salary that the executive received within the twelve-month period ending on the date of the Change of Control, and “annual bonus” means the executive’s highest annual bonus paid during the period beginning five years prior to the Change of Control and ending on the date of the executive’s termination of employment. Executives also are credited with an additional three years of service under the Pension Plan and are eligible to retire after age 55 without reduction in benefits and with a lump sum payment based on a 0% discount rate. Martin Marietta must also continue to provide the executive all benefits provided under Martin Marietta’s defined benefit and defined contribution retirement plans and provide the executive with the same retiree medical benefits that were in effect for retirees immediately prior to the Change of Control. The agreements also have confidentiality requirements to ensure that the executives do not disclose any confidential information relating to Martin Marietta.

The agreements were amended in December 2018 in response to the 2018 Say On Pay vote that was supported by 78.9% of the shareholders that voted. The amendments eliminated (1) the “gross up” payments that compensate the executives for any golden parachute excise taxes imposed under the Internal Revenue Code; (2) the “walk-right” if the executive voluntarily terminates his or her employment for any reason during the thirty-day period following the second anniversary of the Change of Control; and (3) the inclusion of the value of perquisites in the severance payment provided for in the agreements.

The term of the agreements is one year following their effective dates. On each anniversary date of the effective date, the agreements are renewed for one additional year, unless either party gives notice of its intent to cancel the automatic extension. If, prior to termination, a Change of Control occurs or the Board becomes aware of circumstances which in the ordinary course could result in a Change of Control, then under no circumstances will the agreements terminate prior to the second anniversary of the Change of Control.

In addition, the Stock Plan, pursuant to which equity-based awards are made to the executive officers, provides that upon the occurrence of a Change of Control of Martin Marietta as provided in the Employment Protection Agreements, all time periods for purposes of vesting in, or realizing gain from, any outstanding award under the plan will automatically accelerate. For purposes of such vesting, any performance criteria will be deemed achieved at the greater of target performance and actual performance, as measured through the date of the Change of Control. In December 2018, in response to the 2018 Say On Pay vote, the Company’s form of RSU award agreement and PSU award agreement were changed such that future grants of RSUs and PSUs will require termination of the executive’s employment in connection with a Change of Control in order for accelerated vesting to occur.

CEO Pay Ratio Disclosure

The Company is required to disclose in its Proxy Statement the annual total compensation of the median-compensated employee of, generally, all Company employees (excluding the CEO), the annual total compensation of its CEO, and the ratio of the CEO compensation to the median employee’s compensation.

The Company in 2020 employed approximately 8,700 employees who were located primarily in the United States, but also had in Canada and The Bahamas.

As permitted by SEC rules, we may identify our median employee for purposes of providing pay ratio disclosure once every three years and calculate and disclose total compensation for that employee each year; provided that, during the last completed fiscal year, there has been no change in the employee population or employee compensation arrangements that we reasonably believe would result in a significant change to the prior CEO pay ratio disclosure. We reviewed the changes in our employee population and employee compensatory arrangements and determined there has been no change in our employee population or employee compensatory arrangements that would significantly impact the pay ratio disclosure and thus require us to identify a new median employee. As a result, we are using the same median employee as we did in the CEO pay ratio disclosure included in our Proxy Statement filed with the SEC on April 10, 2019, and April 16, 2020, as summarized below. The median employee compensation was identified using a consistently applied compensation measure, encompassing base salary, overtime, incentive compensation with a performance period of one year or less (such as annual incentives and sales or other bonuses), and allowances (such as personal use of company-provided vehicles). As allowed under the SEC rules, base pay was annualized for employees hired during the year to reflect a full year of service.

We determined the required ratio by:

• |  | calculating the compensation based on a consistently applied measure as described above of all employees except the CEO, and then sorting those employees from highest to lowest;

• |  | determining the median employee from that list, including evaluating employees situated slightly above and below the calculated median to ensure the selected employee reflects our population as a whole; and

• |  | calculating the total annual compensation of our CEO and of the median employee using the same methodology required for the Summary Compensation Table.

The total annual compensation for our CEO for fiscal year 2020 was $12,818,588. The total annual compensation in 2020 for the median employee (other than our CEO) was $94,643. The resulting ratio of CEO pay to the pay of our median employee for fiscal year 2020 is 135 to one.

We believe this pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. Because the SEC rules for identifying the median-compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the amount of compensation of the median-compensated employee and the pay ratio reported by other companies may not be comparable to our estimates reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Proposal 3: |  | Advisory Vote on the Compensation of
Our Named Executive Officers

Public companies are required to provide their shareholders with a periodic opportunity to endorse or not endorse their executive officer pay program and policies. The Board of Directors has elected to do so annually and intends to present the following non-binding resolution for approval by shareholders at the Annual Meeting:

“RESOLVED, that the shareholders approve, on an advisory basis, the overall compensation paid to Martin Marietta’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K in this Proxy Statement in the Compensation Discussion and Analysis and in the narrative and tabular disclosure under the heading “Executive Compensation.”

Shareholders are urged to read the Compensation Discussion and Analysis and consider the various factors regarding compensation that are discussed. We believe that our executive compensation program is reasonable, competitive and strongly focused on pay-for-performance principles. Our executive compensation policies have enabled us to implement our compensation philosophy and achieve its goals. We believe that compensation awarded to our named executive officers in 2020 was appropriate and aligned with 2020 performance and positions us for growth in future years. The results of the vote on this resolution are advisory and will not be binding upon the Board of Directors. However, the Board values our shareholders’ opinions, and consistent with our record of shareholder engagement, will consider the outcome of the vote in making future executive compensation decisions. The next such vote will occur at the 2022 Annual Meeting.

If Martin Marietta is dissolved or liquidated, or if substantially all of its assets are sold or there is a merger or consolidation and the acquiring or surviving entity does not substitute equivalent awards for the awards then outstanding, each award granted under the TXI Legacy Plan will become fully vested and exercisable and all restrictions on it will lapse. All options and stock appreciation rights not exercised upon the occurrence of such a corporate event will terminate, and the Company may, in its discretion cancel all other awards then outstanding and pay the award holder its then current value as determined by the Committee.

Description of the Deferred Compensation Plan

The TXI DC Plan became effective as of July 11, 2012 and will terminate on July 11, 2022 unless sooner terminated. Key management legacy employees of TXI, its subsidiaries and its affiliates are eligible to participate in the TXI DC Plan. Under the terms of the TXI DC Plan, participants may elect each year to defer all or a portion of their eligible compensation received during that year. However, no further awards will be granted under the TXI DC Plan, as indicated by management in connection with the approval by shareholders of the Stock-Based Award Plan on May 19, 2017.

If Martin Marietta is dissolved or liquidated, or if substantially all of its assets are sold (or there is a merger or consolidation) and the acquiring or surviving entity does not substitute equivalent awards for the awards then outstanding, each award granted under the TXI DC Plan will become fully vested and all restrictions on it will lapse.

Annual Meeting and Voting Information

What is the purpose of the Annual Meeting?

At our Annual Meeting, shareholders will act on the matters outlined in the accompanying Notice of Annual Meeting of Shareholders. This statement is furnished in connection with the solicitation by Martin Marietta’s Board of Directors of proxies to be used at the meeting and at any and all adjournments or postponements of the meeting.

Whether or not you plan to attend the meeting, we encourage you to date, sign, and return your proxy in the enclosed envelope or electronically as instructed in the notice of this Proxy Statement and below under How do I vote?.

Who is entitled to vote at the meeting?

Only shareholders of record at the close of business on March 5, 2021 are entitled to notice of and to participate in the Annual Meeting. If you were a shareholder of record on that date, you will be entitled to vote all the shares that you held on that date at the meeting, or any adjournments or postponements of the meeting.

What are the voting rights of the holders of Martin Marietta common stock?

Each share of Martin Marietta common stock is entitled to one vote on each matter considered at the meeting.

Who can attend the meeting?

All shareholders as of the record date, or their duly appointed proxies, beneficial owners presenting satisfactory evidence of ownership as of the record date, and invited guests of Martin Marietta may attend the meeting.

What constitutes a quorum?

The presence at the meeting, in person or by proxy, of the holders of a majority of the common stock outstanding on the record date constitutes a quorum, permitting shareholders to take action at the meeting. On March 5, 2021, there were 62,360,086 shares outstanding of Martin Marietta’s common stock, $.01 par value per share.

Who will oversee the voting results?

Votes cast by proxy or in person at the Annual Meeting will be tabulated by an independent inspector of election appointed by Martin Marietta’s Board of Directors for the Annual Meeting. The inspector of election will determine whether a quorum is present. For purposes of determining the presence of a quorum, abstentions and broker non-votes (which are described below) will be counted as shares that are present and entitled to vote.

How do I vote?

Registered shareholders: Registered shareholders have four voting options:

• |  | over the Internet at the internet address shown on the enclosed Proxy Card;

• |  | by telephone through the number shown on the enclosed Proxy Card;

• |  | by completing, signing, dating and returning the enclosed Proxy Card by mail; or

• |  | in person at the meeting.

Even if you plan to attend the meeting, we encourage you to vote your shares by submitting your proxy. If you choose to vote your shares at the meeting, please bring proof of stock ownership and proof of your identity for entrance to the meeting.

Beneficial shareholders: If you hold your Martin Marietta shares in street name, your ability to vote by internet or telephone depends on the voting process of the bank, broker or other nominee through which you hold the shares. Please follow their directions carefully. If you want to vote at the meeting, you must request a legal proxy from your bank, broker or other nominee and present that proxy, together with proof of your identity, for entrance to the meeting.

ANNUAL MEETING AND VOTING INFORMATION ◆

If you complete and properly sign the accompanying Proxy Card and return it to Martin Marietta, it will be voted as you direct. If you are a registered shareholder and attend the meeting, you may deliver your completed Proxy Card or vote in person. Shareholders whose shares are held by brokers, banks, or other nominees who wish to vote at the meeting will need to obtain a proxy form from the institution that holds its shares.

What can I do if I change my mind after I vote my shares?

Even if you have submitted your vote, you may revoke your proxy and change your vote at any time before voting begins at the Annual Meeting.

Registered shareholders: Registered shareholders may change their votes in one of two ways:

• |  | by voting on a later date by telephone or over the Internet (only your last dated Proxy Card or telephone or Internet vote is counted); or

• |  | by delivering a later dated Proxy Card to our Secretary, either prior to or at the meeting; or by voting your shares in person at the meeting. In order to vote your shares at the meeting, you must specifically revoke a previously submitted proxy.

Beneficial shareholders: If you hold your shares in street name, you should contact your bank, broker or other nominee to find out how to revoke your proxy.

How do I vote my 401(k) shares?

Each participant in Martin Marietta’s Savings and Investment Plan may direct the trustee as to the manner in which shares of common stock allocated to the plan participant’s account are to be voted. If the plan participant does not return a signed voting instruction card to the trustee in a timely manner or returns a card without indicating any voting instructions, the trustee will vote the shares in the same proportion as shares for which the trustee receives voting instructions for that plan.

Will my broker vote my shares for me if I do not give voting instructions? What are “broker non-votes”?

Brokers holding shares for beneficial owners must vote those shares according to the specific instructions they receive from the beneficial owners. If specific instructions are not received, brokers may generally vote these shares at their discretion. However, the NYSE rules preclude brokers from exercising their voting discretion on certain proposals, such as the election of Directors and executive compensation matters. In such cases, absent specific instructions from the beneficial owner, the broker may not vote on those proposals. This results in what is known as a “broker non-vote.” The approval of the ratification of the appointment of independent auditors is not a proposal subject to this rule. Accordingly, if you want your broker to vote your shares on the election of Directors or, the approval on an advisory basis of the compensation of our named executive officers, you must provide specific voting instructions to your broker. Conversely, any broker holding shares for you may vote your shares at their discretion with respect to the ratification of the appointment of independent auditors unless you give them specific instructions on how you wish for them to vote.

What vote is required to approve each item?

Martin Marietta amended its Articles of Incorporation following the 2013 Annual Meeting of Shareholders to provide for majority voting in the election of Directors. As a result, in an uncontested Director election (i.e., an election where the only nominees are those proposed by our Board of Directors, such as at the 2021 Annual Meeting), Directors are elected by a majority of the votes cast by holders of our common stock present in person or by proxy at the meeting. For purposes of uncontested Director elections, a majority of votes cast means that the number of votes cast “for” a nominee’s election exceeds the number of votes cast “against” that nominee’s election. Abstentions and broker non-votes will not be counted as votes cast in the election of Directors and will have no effect on the outcome of the election of Directors.

Under North Carolina law, if an incumbent director is not re-elected at an Annual Meeting, then, even though his or her term has expired, the incumbent director continues to serve in office as a holdover director until his or her successor is elected or until there is a decrease in the number of directors.

80 2021 PROXY STATEMENT |  |  |  |

##### Table of Contents

◆ ANNUAL MEETING AND VOTING INFORMATION

North Carolina law further provides that if the shareholders fail to elect the full authorized number of directors, a board of directors may fill the vacancy by electing a successor. Accordingly, Martin Marietta’s Articles of Incorporation provide that if a nominee is not elected by a vote of the majority of the votes cast with respect to that nominee’s election, the Board of Directors may decrease the number of Directors, fill any vacancy or take other appropriate action.

The ratification of the selection of independent auditors, the advisory vote to approve the compensation of the named executive officers, and any other proposal presented at the meeting, will be approved if more votes are cast by proxy or in person in favor of the proposal than are cast against it.

Abstentions and broker non-votes, if any, will not be counted “for” or “against” any of these proposals.

What is required to attend the meeting?

Attendance at the Annual Meeting will be limited to our shareholders as of the record date of March 5, 2021 and their proxies. If you are a shareholder and plan to attend the Annual Meeting and your shares are held in street name (for example, if your shares are held through an account maintained by a bank or securities broker), you must present evidence of your stock ownership as of March 5, 2021 in order to be admitted to the Annual Meeting. You can obtain this evidence from your bank or brokerage firm. If your shares are held in street name as of March 5, 2021 and you intend to vote your shares at the Annual Meeting, you must also request a legal proxy appointment from your bank, broker or other nominee and present that proxy appointment at the Annual Meeting’s registration desk. Whether you are a registered shareholder, your shares are held in street name, or you are a duly authorized proxy for a shareholder, a government-issued identification will be required to obtain admittance to the Annual Meeting.

We speak to almost all of our largest shareholders each year and we rarely have any shareholders in attendance at our shareholders’ meetings. In addition, the proposals to be considered at the 2021 Annual Meeting are routine. For these reasons, we currently intend to hold the Annual Meeting in person. We are actively monitoring developments regarding COVID-19 and are sensitive to public health concerns and the protocols that federal, state, and local governments may impose. In the event that alternative arrangements for the Annual Meeting are required, we intend to promptly advise our shareholders. Please monitor our website, https://ir.martinmarietta.com/events-presentations, for updated information if you are planning to attend the Annual Meeting. To assist with logistical planning for the Annual Meeting, we request that shareholders planning on attending the Annual Meeting notify us by email at corporatesecretary@martinmarietta.com. Providing such notice is not required for attendance at the Annual Meeting and is requested solely to assist in our planning.

What protocols will be in place to protect the safety of those who attend the Annual Meeting?

In response to the COVID-19 pandemic, health and safety protocols will be followed at the Annual Meeting. All seating will be appropriately spaced to ensure proper social distancing and attendees will be required to wear a mask.

Where can I find voting results for the Annual Meeting?

We will announce preliminary voting results at the conclusion of the meeting and publish final results in a Current Report on Form 8-K filed with the SEC within four business days after the Annual Meeting.

Where can I find out more information about Martin Marietta?

We maintain a website at www.martinmarietta.com where you can find additional information about Martin Marietta. Visitors to the website can view and print copies of Martin Marietta’s SEC filings, including periodic and current reports on Forms 10-K, 10-Q and 8-K, as soon as reasonably practicable after those filings are made with the SEC.

Shareholders’ Proposals for 2022 Annual Meeting

Proposals by shareholders intended to be presented at the 2022 Annual Meeting of Shareholders of Martin Marietta must be received by the Secretary of Martin Marietta no later than December 14, 2021 in order to be included in the Proxy Statement and on the Proxy Card that will be solicited by the Board of Directors in connection with that meeting. The inclusion of any proposal will be subject to applicable rules of the SEC.

In general, written notice must be received by the Secretary of Martin Marietta at its principal executive office, 4123 Parklake Avenue, Raleigh, North Carolina 27612, not less than 60 days nor more than 90 days prior to the first anniversary of the mailing of the preceding year’s Proxy Statement in connection with the Annual Meeting and must contain specified information concerning the matter to be brought before such meeting and concerning the shareholder proposing such a matter. Accordingly, to be considered at the 2022 Annual Meeting, proposals must be received by the Secretary of Martin Marietta no earlier than January 13, 2022 and no later than February 11, 2022. Any waiver by Martin Marietta of these requirements with respect to the submission of a particular shareholder proposal shall not constitute a waiver with respect to the submission of any other shareholder proposal nor shall it obligate Martin Marietta to waive these requirements with respect to future submissions of the shareholder proposal or any other shareholder proposal. Our Bylaws provide a proxy access right to permit a shareholder, or a group of up to 20 shareholders, owning at least 3% of our outstanding common stock continuously for at least three years, to nominate and include in our proxy materials director nominees constituting up to 25% of the Board of Directors or two Directors, whichever is greater, provided that the shareholder(s) and the nominee(s) satisfy the requirements specified in our Bylaws. Under our Bylaws, compliant notice of proxy access Director nominations for the 2022 Annual Meeting must be submitted to the Corporate Secretary of Martin Marietta no earlier than November 13, 2021 and no later than December 13, 2021.

Appendix A

Martin Marietta

Guidelines for Potential New Board Members

Preamble: The following considerations are one of the tools used to assist the Nominating and Corporate Governance Committee in the exercise of its responsibility to evaluate the suitability of new potential candidates for the Board of Directors, consistent with any criteria set out in Martin Marietta’s Corporate Governance Guidelines. In evaluating a new potential candidate who is not an employee or former employee of Martin Marietta, the Nominating and Corporate Governance Committee would take into consideration the extent to which the candidate has the personal characteristics and core competencies outlined in one or more of the guidelines set out below, and would take into account all other factors it considers appropriate, including the overall composition of the Board. These guidelines are in addition to and are not intended to change or interpret any law or regulation, or Martin Marietta’s Articles of Incorporation or Bylaws. The guidelines are subject to modification from time to time by the Nominating and Corporate Governance Committee.

1. | Candidates should have a long-term history of the highest integrity and should ascribe fully to the ethics program of Martin Marietta.

2. | Candidates should be experienced, seasoned and have mature business judgment. It would be desirable if they are still active in their careers.

3. | Consideration should be given to matching the geographic base of the candidate with the geographic coverage of Martin Marietta.

4. | Consideration should be given to diversity on the Board. Such diversity may include type of experience, education, skill sets, ethnic origin, gender and other items that will enable the Board to have a broad knowledge base and diverse viewpoints.

5. | Generally, candidates should not come from firms or companies that are significant sellers or buyers of goods and services to or from Martin Marietta.

6. | Candidates who would serve on Martin Marietta’s Audit Committee, Nominating and Corporate Governance Committee, or Management Development and Compensation Committee should be “independent” as defined by the Securities and Exchange Commission, the New York Stock Exchange and Martin Marietta’s Corporate Governance Guidelines.

7. | Given the nature of Board governance, the background and expertise of candidates should reflect the skill needs of the Board and Martin Marietta. With the Securities and Exchange Commission requirements with respect to audit committees and the financial nature of much of what the Board is responsible for, a significant number of Board members need to have strong financial knowledge.

8. | Candidates should have significant professional experience to make a significant contribution to the Board such that the overall composition of the Board includes expertise in the following areas: audit committee financial experts, legal, human resources, business strategy, marketing, the primary businesses in which Martin Marietta operates, and other areas of importance to Martin Marietta.

9. | Public company experience is highly desirable.

10. | Candidates from education or nonprofit organizations will be considered where there is a specific priority need identified by the Board and where such a candidate can add value.

11. | Board candidates ideally would serve on no more than three for-profit boards inclusive of Martin Marietta Materials to assure adequate time to discharge the duties of a Board member.

Non-GAAP Measures

Non-GAAP financial measures disclosed by management are provided as additional information to investors in order to provide them with an alternative method for assessing our financial condition and operating results, and are often requested by investors. These measures are not in accordance with, or a substitute for, GAAP and may be different from or inconsistent with non-GAAP financial measures used by other companies. Adjusted EBITDA is an indicator used by the Company and investors to evaluate the Company’s operating performance period to period.

EBITDA is a widely accepted financial indicator of a company’s ability to service and/or incur indebtedness. EBITDA is not defined by GAAP and, as such, should not be construed as an alternative to earnings from operations, net earnings or operating cash flow.

The following presents a reconciliation of net earnings attributable to Martin Marietta to consolidated adjusted EBITDA for the years ended December 31, 2020, 2019 and 2010.

Consolidated Adjusted EBITDA for year ended December 31:

(dollars in millions) |  | 2020 |  |  | 2019 |  |  | 2010 |
Net Earnings Attributable to Martin Marietta |  | $ | 721.0 |  |  | $ | 611.9 |  |  | $ | 97.0 |
Add back: |  |  |  |  |  |  |  |  |  |  |  |
Interest expense, net of interest income |  |  | 117.6 |  |  |  | 128.9 |  |  |  | 68.5 |
Income tax expense for controlling interests |  |  | 168.2 |  |  |  | 136.3 |  |  |  | 29.3 |
Depreciation, depletion and amortization expense and earnings/loss from nonconsolidated equity affiliates |  |  | 386.0 |  |  |  | 377.4 |  |  |  | 182.3 |
Consolidated Adjusted EBITDA |  | $ | 1,392.8 |  |  | $ | 1,254.5 |  |  | $ | 377.1 |
Consolidated Total Revenues |  | $ | 4,729.9 |  |  | $ | 4,739.1 |  |  |  |  |
Adjusted EBITDA Margin |  |  | 29.4 | % |  |  | 26.5 | % |  |  |  |

The leverage ratio is our consolidated debt to consolidated Adjusted EBITDA for the trailing twelve months. Management uses this ratio to assess its capacity for additional borrowings. The following calculation as of December 31, 2020 is not intended to be a substitute for the Company’s leverage covenant under its credit facility:

(dollars in millions) |
Net Earnings Attributable to Martin Marietta |  | $ | 721.0 |
Add back: |  |  |  |
Interest expense, net of interest income |  |  | 117.6 |
Income tax expense |  |  | 168.2 |
Depreciation, depletion and amortization expense and earnings/loss from nonconsolidated equity affiliates |  |  | 386.0 |
Consolidated Adjusted EBITDA for the twelve months ended December 31, 2020 |  | $ | 1,392.8 |
Consolidated debt at December 31, 2020 |  | $ | 2,625.8 |
Consolidated debt-to-consolidated EBITDA at December 31, 2020 for trailing-twelve months Consolidated Adjusted EBTIDA |  |  | 1.9x |

Adjusted earnings per diluted share (Adjusted EPS) for the year ended December 31, 2018 excludes the impact of acquisition-related expenses, net; the impact of selling acquired inventory due to the markup to fair value as part of acquisition accounting; and the asset and portfolio rationalization charge.

Adjusted EPS for the year ended December 31, 2017 excludes the one-time impact of the Tax Cuts and Jobs Act of 2017.

Management presents this non-GAAP measure to more accurately report the performance of the Company excluding these nonrecurring items.

The following reconciles reported earnings per diluted share to Adjusted EPS for the years ended December 31, 2018 and 2017.
