    <div style="text-align: left; text-indent: 36pt; font-family: 'Times New Roman'; font-size: 10pt;">At Martin Marietta Materials, Inc.&#8217;s (the &#8220;Company&#8221;) 2023 Annual Meeting of Shareholders on May 11, 2023, a majority of shareholders (74%) supported the
      Company&#8217;s annual advisory vote to approve the compensation of the Company&#8217;s named executive officers or &#8220;Say-on-Pay&#8221; proposal.&#160; However, since this was lower than the level of support the proposal has received in recent years, the Management
      Development and Compensation Committee of the Company&#8217;s Board of Directors (the &#8220;Committee&#8221;) undertook a thorough review of the Company&#8217;s executive compensation programs, and solicited additional feedback from the Company&#8217;s shareholders during its
      regular shareholder engagement process.&#160; While shareholder feedback generally supported the Company&#8217;s executive compensation programs and its strong alignment with performance, shareholders expressed a desire for enhanced disclosure regarding the
      structure of the program, including its performance metrics and weightings, and some expressed a preference for a formulaic program.</div>

    <div><br />
    </div>

    <div style="text-align: left; text-indent: 36pt; font-family: 'Times New Roman'; font-size: 10pt;">Following its review, and considering shareholder feedback, the Committee decided to modify the structure of the Company&#8217;s annual bonus program so that
      annual bonuses for executives, beginning with 2023 bonuses, will be determined as follows:&#160; (i) 80% of an executive&#8217;s bonus will be determined based on the achievement of pre-determined financial metrics; and (ii) 20% of the executive&#8217;s bonus will be
      determined based on the achievement of pre-determined environmental, social, and governance and safety metrics.&#160; Final bonus payouts will be subject to an individual performance modifier of up to 20%, which will be determined by the Committee based
      on its evaluation of the executive&#8217;s performance for the applicable year and enable the Committee to ensure that annual bonuses maintain their strong link to the Company&#8217;s performance.&#160; The Company plans to disclose the financial, environmental,
      social and governance and safety metrics and their respective weightings in its annual proxy statement for its 2024 Annual Meeting of Shareholders.</div>

    <div><br />
    </div>

    <div style="text-align: left; text-indent: 36pt; font-family: 'Times New Roman'; font-size: 10pt;">The Company plans to discuss these modifications with certain shareholders and proxy advisory firms as part of its continuing shareholder engagement.</div>
