Trade Associations

We are a member of various national and state trade associations, in addition to the U.S. Chamber of Commerce, that
make political contributions. We believe all the groups of which we are a member share and otherwise further our goals,
as well as providing both a useful forum for discussing issues of general industry significance and an effective platform for
advocating positions on issues of importance to the members, including Martin Marietta. We periodically review lobbying
registrations submitted by these associations as part of our continuing membership and do not believe any have taken any
position as part of their lobbying efforts that are inconsistent with our stated strategy or in conflict with the interest of our
shareholders, though from time to time such associations may take positions on issues that are not fully representative of
ours. Overall, we believe that Martin Marietta’s membership in such associations is in the long-term interests of the
Company and its shareholders. Our total indirect lobbying payments made in 2024 were $248,164. The four national
trade associations to whom we have paid dues that include a portion that goes towards lobbying or political donations
are the National Stone Sand & Gravel Association, the National Ready Mixed Concrete Association, the National Asphalt
Pavement Association, and the U.S. Chamber of Commerce.

Lobbying on Infrastructure and Climate Change

Given our businesses’ relatively low GHG emissions profile, Martin Marietta does not conduct, at the federal or state level,
any direct lobbying on climate change matters. We periodically review positions taken by the trade associations of which
we are a member and are not aware of any recent lobbying efforts that are inconsistent with the Paris Agreement.

• The Portland Cement Association (PCA), the only cement industry association in which we are a member, recently
adopted and published its own “Roadmap to Carbon Neutrality” for the cement and concrete industry, looking across
the value chain from clinker production to carbon capture and sequestration (CCS). Among other things, the Roadmap
