            and portfolio rationalization charge (Adjusted EBITDA) is an indicator used by the Company and investors to evaluate the Company&#8217;s operating performance from period to period. Effective January 1, 2024, transaction expenses and inventory
            acquisition accounting impacts are only excluded for transactions with at least $2 billion in consideration and transaction expenses expected to exceed $15 million. Management believes Adjusted EBITDA provides investors with a useful tool to
            evaluate the Company&#8217;s ongoing business, performance from period to period and anticipated performance. Adjusted EBITDA is not defined by generally accepted accounting principles and, as such, should not be construed as an alternative to
            earnings from operations, net earnings attributable to Martin Marietta or operating cash flow.

    <font style="font-family: Arial;"><br>
    </font>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;">After nearly eight years with Martin Marietta, <font style="font-size: 10pt; font-weight: bold;">James (Jim) A.J. Nickolas</font> has decided to depart as Executive Vice President
      and Chief Financial Officer, effective immediately, to move his family back to their beloved hometown. Jim will join a Chicago-based publicly traded company, as its Chief Financial Officer.</div>
    <div style="font-family: Arial;">&#160;</div>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;">Over the course of his Martin Marietta tenure, Jim has been an integral member of the executive leadership team and a valued colleague. With his deep financial acumen, he has played
      a key role in responsibly growing the business through strategic acquisitions and organic capital investments while maintaining a strong balance sheet and investment grade credit rating. I thank him for his meaningful contributions, including the
      development of the talent in our finance organization that has supported the Company in both growing and maintaining our position as a market-leading supplier of aggregates.</div>
    <div style="font-family: Arial;"><br>
    </div>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;">In his resignation, Jim underscored that working alongside our capable and dedicated team was a career highlight, and that he has the utmost faith in Martin Marietta&#8217;s future and is
      confident the best is yet to come as our teams continue to execute our proven strategy for the benefit of our stakeholders.</div>
    <div><br>
    </div>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;"><font style="font-size: 10pt; font-family: Arial; font-weight: bold;">Robert J. (Bob) Cardin</font> has been appointed as Interim CFO reporting to me, in addition to his current
      responsibilities as Senior Vice President, Controller and Chief Accounting Officer. The Company has initiated a search process of internal and external candidates with the assistance of a leading global executive search firm to identify the Company&#8217;s
      next CFO.</div>
    <div><br>
    </div>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;">In addition, effective immediately, <font style="font-size: 10pt; font-family: Arial; font-weight: bold;">Jason P. Flynn</font>, Senior Vice President and Chief Information
      Officer, will report to me.</div>
    <div style="text-align: justify;"><br>
    </div>
    <div style="text-align: justify; font-family: Arial; font-size: 10pt;">Please join me in wishing Jim, Anastasia and their children all the best in this next chapter as they reunite with family and loved ones.</div>
