Company Highlights

At Martin Marietta, we thoughtfully consider the needs of both stakeholders and shareholders, this has always been at the
forefront for Martin Marietta. Our 2022 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.
