COMPANY OVERVIEW

Company Highlights

While there has been a recent push for companies to more thoughtfully consider the needs of both stakeholders and shareholders,
this has always been at the forefront for Martin Marietta. Our 2021 results underscore our commitment to excellence in all that we
do, as well as the importance of continued responsible investment in our facilities to maintain a safe and healthy workplace. Equally
important is our steadfast investment of time and resources to ensure our employees, customers, vendors, communities and the
environment are taken care of and protected. We believe it is both the smart and right thing to do.
