COMPANY OVERVIEW

Our Employees

Martin Marietta employees play a critical role in enforcing good governance and sustainability practices. It is their
commitment to each other and to our communities that elevates our efforts and performance as a Company. Our
employees understand the importance of acting with integrity in all of their interactions. We provide them with a variety
of resources to guide them in daily decision-making and support them should they have questions.
These resources include an engaged senior leadership team, our Code of Ethical Business Conduct, a confidential ethics
hotline managed by an independent third party, and annual ethics training.
