Direct Lobbying Transparency

Overall Assessment	Comment	Score
Limited	Martin Marietta Materials offers only limited insight into its climate-related lobbying. It acknowledges that it "does not conduct direct lobbying on climate change matters at the federal or state level" and explains that its influence is exercised indirectly through trade groups such as the Portland Cement Association and the U.S. Chamber of Commerce, disclosing the 2022 dues it paid and noting that it "periodically reviews lobbying registrations submitted by these associations." This identifies a single indirect mechanism and names the associations involved, but it does not specify the government bodies or policymakers those groups engage or describe any other channels of advocacy. On the substance of policy, the company refers in broad terms to support for the Paris Agreement, the PCA’s "Roadmap to Carbon Neutrality," and aspirations like “greater market acceptance of alternative fuels usage and low-carbon cement blends,” yet it does not point to any individual bills, regulations or rulemakings it has tried to influence. Likewise, the outcomes it seeks remain general—encouraging lower-carbon cement, CCS development, and carbon-neutrality goals—without detailing concrete legislative or regulatory changes it is pressing for. As a result, the disclosures demonstrate only a rudimentary level of transparency on the policies addressed, the mechanisms employed, and the specific policy results the company hopes to achieve.	1

Lobbying Governance

Overall Assessment	Comment	Score
Moderate	Martin Marietta Materials has a structured governance framework overseeing its political and lobbying activities, including climate-related considerations, with the Finance Committeecomprised exclusively of independent directorssetting spending caps, overseeing expenditures, and reporting to the full Board, while all political expenditures are reviewed by our Chief Financial Officer and final authorization is required from the Chief Executive Officer or an authorized delegate. The company conducts only indirect climate lobbying, noting that 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, and that membership and positions are governed directly by the Companys executive management team, who also provide reports regarding the Companys activities to the Board of Directors. However, Martin Marietta does not conduct any direct lobbying on climate change matters and there is no dedicated climate-lobbying audit or third-party review, nor a public commitment to conduct engagement in line with the goals of the Paris Agreement, given the response No, and we do not plan to have one in the next two years.	2
