Political Contributions and Lobbying

At Martin Marietta, we believe our success depends on the ability to integrate important values into our long-term
corporate strategy. In addition to safety, environmental, employees, communities, and our other important considerations
that advance our sustainable value, this includes making sure that our political expenditures and advocacy are aligned
with our core business strategy, goals and values. In particular, we recognize the importance of monitoring our political
spending and our participation in trade associations, including those that may lobby on climate change-related concerns,
as well as maintaining our robust governance procedures. To continue our transparency with investors regarding these
and other sustainability and climate-related topics, we are providing this information to promote an understanding of the
issues that are important to Martin Marietta in this regard and the governance we have on these actions.
