SAFE OPERATIONS

Despite our growth into new markets, we continued to see
dramatic safety improvements over the prior year. One of the
values we embrace that has enabled this achievement is our
Guardian Angel Creed. With Guardian Angel as the foundation
of our safety culture, safety performance, ownership and
engagement of the safety process extends beyond division lines
and allows our employees to be consistently reminded that each
one of us is responsible for our own and each other’s safety.

In this regard, we established a Safety Task Force in 1999, comprised of employees from across the enterprise who
engaged in extensive benchmarking of companies within and outside of the mining industry. From this effort, the
foundational elements of Martin Marietta’s safety program were developed. Their task was to pursue safety and
occupational health functional excellence. In 2022, our efforts resulted in the continued rollout of the Safety Mentor
Program. This program trained 341 of our experienced employees to be mentors to 841 new hires in respect to safety.
We expect that this program will reduce the number of accidents experienced by new miners as our experienced
employees share their knowledge and encouragement in this important part of our business.
To further emphasize the importance of safety, Martin Marietta presents annually DIAMOND AWARDS, and one of our
facilities receives the DIAMOND ELITE AWARD.
The DIAMOND AWARDS are a recognition and commitment that at Martin Marietta, we view ourselves as an industry
leader, respected for the work we do to help make things possible. Whether it’s roads or bridges or buildings, our
specialty is building strong foundations. The foundation of our success as a Company is the dedicated, talented teams of
employees who day in and day out work hard, safely and ethically to provide our customers with quality products and
materials. We know that our people are our most precious asset, essential to everything we accomplish.

To recognize our employees’ excellent efforts, DIAMOND AWARDS are presented each year to the “best of the best” at
Martin Marietta. Consisting of three tiers (Achievement, Honor and Elite), the DIAMOND AWARDS program rewards
exceptional performance in all of our divisions and business segments.
The criteria for each of our award levels are:
1. No reportable safety incidents during the previous calendar year;

2. No environmental notices of violation during the previous calendar
year; and
3. Return on assets that exceeds the Company’s weighted average cost
of capital for the previous calendar year, in addition to other financial
performance.

All operations that achieve this criteria receive Martin Marietta’s Diamond
Achievement Award. To be considered for a Diamond Honor Award,an
operation must meet the criteria for no environmental violations and the
financial metric for three consecutive years. They must also show continuous
safety improvement over a three-year period, with zero incidents the third
year. The Diamond Elite Award winner is recognized for performance and
achievements above all the rest.
