/ SUMMARY OF OUR COMPENSATION CONSIDERATIONS

Safety

2023 was another year of world-class safety performance which strengthens our belief that Zero is Possible. This means
operating our business without any safety incidents. Our goal is zero. We look to world-class companies and safety
incident rates for guidance as to how we achieve this. We continued to make significant progress in 2023 towards this
important goal, driven by extraordinary employee focus and increased engagement.

While all awards are meaningful, it is particularly satisfying when we are recognized for achievement of one of our core
values. Martin Marietta’s Augusta Quarry in Georgia was recognized by the National Stone, Sand and Gravel
Association (NSSGA) as a bronze-level Safety Excellence Award winner in 2023. This award recognizes operations that
have gone the longest duration without a reportable incident in their size category, based on data provided by the
U.S. Department of Labor’s Mine Safety and Health Administration. As an enterprise, Martin Marietta received bronze-level
honors in the large company category by the NSSGA in its Louis Greisemer Sterling Safety Awards.

Additionally, two Martin Marietta sites, Racoon River Sand and Midlothian Cement, earned Sentinels of Safety Awards from
the National Mining Association in 2023. This award is the oldest and most esteemed honor in the mining industry,
recognizing mining teams that record the most hours in a calendar year without a single lost-time injury. The National Ready
Mixed Concrete Association (NRMCA) recognized 50 Martin Marietta ready-mixed concrete plants for gold-level Excellence in
Safety achievement in 2023, and the Portland Cement Association presented its Chairman’s Safety Award to Martin
Marietta’s Midlothian Cement Plant in Texas.

We achieved our seventh-consecutive year of world-class Lost-Time Incident Rate
(LTIR) performance and our third-consecutive year of world-class Total Incident Injury
Rate (TIIR) performance

With the goal of continuous improvement in safety, aligned with our world class vision, and our belief that zero is possible, we
introduced several new safety-related efforts in 2023 to support our Guardian Angel safety culture and help further strengthen
our safety practices for the future. Specifically, we established a Safety Executive Steering Committee to guide and maintain our
focus on an overall safety strategy, and we completed a comprehensive organizational safety assessment led by a newly
established Safety Task Force. The Task Force’s efforts included a companywide safety survey, employee listening sessions and
focus groups, and other activities. In addition to the positive results from these efforts, the Safety Task Force, with a commitment
to continuous improvement and preventing complacency, developed a road map that will be followed to pursue continuous
safety improvement in 2024 and beyond.

For Martin Marietta, safety performance sets our foundation for long-term financial strength and successful
SOAR execution. Simply said, a safe operation is a profitable one.
