SAFE OPERATIONS

World-Class Safety Performance

Given the nature and physical demands of our quarrying activities,
operating our business safely is at the core of our long-term success
and our ability to continue delivering value. We believe our
employees are our most valuable asset, and, in 2021, we continued
our impressive safety performance.

“In 2021, our lost-time incident rate was
0.17, meaning 99.8 percent of our ~10,000

employees experienced zero lost-time
incidents, a world-class level for the fifth

straight year.”

And our 2021 performance is the again one of best safety records in Martin Marietta’s history, despite nearly continuous
operations, with Company-wide lost time and total injury incidents exceeding world-class levels. In 2021, our total injury
incident rate (TIIR) of 0.84, exceeded the world-class rate of 0.90 for the first time, inclusive of acquired operations.
Also, our lost-time incident rate was 0.17, meaning 99.8 percent of our ~10,000 employees experienced zero lost-time
incidents, achieving a world-class level for the fifth straight year. We believe that we are on the right track to realizing our
goal of zero incidents and our Guardian Angel safety culture is a key part of our ongoing efforts to keep our employees safe.
