CEO Letter

A Message From Our CEO

To our Stakeholders,

For Martin Marietta and our employees, 2020 was an unprecedented year of uncertainties, resiliency, progress and
growth. I am grateful and proud to say that our Company has been navigating the challenges of a historic pandemic
while delivering record-setting financial, safety and other performance as we also support our local communities. We
believe these accomplishments demonstrate both our commitment, and how we are positioned, to create a positive,
lasting impact and to succeed in delivering exceptional, sustainable value to our employees, customers, investors and the
communities in which we live and operate. This report will provide you with more details on these important topics.

In last year’s letter, published in April 2020 at the beginning of the coronavirus (COVID-19) outbreak, I noted that we,
together with our Board of Directors, were actively monitoring emerging developments, taking steps to prepare for and
respond to the challenges and uncertainties posed by the pandemic, and proactively implementing responsible actions
across our enterprise to keep our employees, stakeholders and business safe and healthy. Throughout 2020, and as of the
date of this letter, we have remained open for business, and as we continued to meet our customers’ needs, the
Company achieved record profits and earnings.

*Adjusted EBITDA and earnings per diluted share for 2020 included $70 million and $0.87, respectively, of nonrecurring gains on surplus, non-core land sales and divested
assets. Adjusted EBITDA is a non-GAAP financial measure. See Appendix for reconciliation to nearest GAAP measure.

To do this, we established internal task forces on COVID-19 planning and employee communications, implemented robust
health safety protocols consistent with the recommendations of the Centers for Disease Control and Prevention and
maintained close contact with our industrial hygienist group doctors. This has included rules for social distancing, enhanced
cleaning, canceling all non-essential in-person meetings and business travel, and establishing contingency plans with respect
to facility staffing, all of which resulted in recording to date only a handful of employee-to-employee transmission cases.

Our ability to manage the potential risks of COVID-19 to our business, even while being an essential business and
operating every day all across the country, is both a reflection of, and testament to, the care we have for our employees’
well-being and our commitment to operating our business responsibly.
