LETTER TO SHAREHOLDERS

Long-term Martin Marietta shareholders already know these matters are important to us. Yet, for all of our investors’ benefit,
please know that we believe adhering to these principles requires continuous effort and long-term commitment, including
seeking new opportunities for improved performance with respect to each pillar. Doing so is part of our culture; the overarching
focus of last year’s Annual Letter. Culture drives us to lead with a purpose that makes Martin Marietta and the communities and
people we engage with sustainable. We believe this is a powerful force – one that positively impacts our employees, customers,
vendors, and other stakeholders and business results and helps us accomplish our strategic goals. We pledge to the continued
enhancement of our engagement and reporting on these critical matters, as well as our corporate governance achievements, in
our Annual Report, Proxy Statement and Sustainability Report.

We look forward to building on our strong momentum. Through our diligent and disciplined strategic development, timely and
prudent acquisitions, and our unwavering commitment to safety, we plan to continue our strong financial performance, while
staying true to the principles that are central to our culture and business, and successfully execute our strategic plan in the
coming years.
In closing, I want to share some important news. Steve Zelnak, our long-time director, will be retiring from the Board of Directors
in May 2020 upon reaching our mandatory retirement age. Steve was previously the Chief Executive Officer of Martin Marietta
from 1982, when the aggregates business was a $140 million subsidiary of Lockheed Martin, until 2010. He oversaw the
Company’s initial public offering in 1994, and drove its remarkable growth through the 1990s and 2000s. Steve has been a
visionary and a steadfast, dedicated and important voice on the Martin Marietta Board of Directors. We are forever grateful for
all he has done for the company, its investors and stakeholders.
Finally, none of our accomplishments would be possible were it not for the hard work and dedication of Martin Marietta’s nearly
9,000 employees. It is they who deserve our heartfelt thanks and gratitude, along with your devoted Board of Directors for their
ongoing support and counsel.

Respectfully yours,

C. Howard Nye
Chairman, President and Chief Executive Officer
