SAFE OPERATIONS

World-Class Safety Performance

Given the nature and physical demands of our building materials
production activities, operating our business safely is at the core of
our long-term success and our ability to continue delivering value.
We know our employees are our most valuable asset, and, in 2024,
we continued our impressive safety performance.

“In 2024, our lost-time incident rate was

0.129, meaning 99.9 percent of our ~9,400
employees experienced zero lost-time

incidents, a world-class level for the eighth
Earthell Latta, straight year.”

Our 2024 performance is again one of best safety records in Martin Marietta’s history, with companywide lost time and total
injury incidents exceeding world-class levels. In 2024, our total injury incident rate (TIIR) of 0.65, exceeded the world-class
rate of 0.90 for the fourth year in a row, inclusive of acquired operations. Also, our lost-time incident rate was 0.129,
meaning 99.9 percent of our ~9,400 employees experienced zero lost-time incidents, achieving a world-class level for the
eighth 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.
