At Martin Marietta, we thoughtfully consider the needs of both stakeholders and shareholders. Our 2024 results underscore our
resiliency and the strength of our business and strategic plan, as well as the importance of continued responsible investment in our

our employees, customers, vendors, communities and the environment are taken care of and protected. We believe our focus on
