COMPANY OVERVIEW

Committed to Safety

2024 was the Company’s safest year on record, with a companywide Total Injury Incident Rate (TIIR) of 0.65, again
exceeding the world-class rate of 0.90, inclusive of acquired operations. For the eighth consecutive year, we also attained
a world-class Lost-Time Incident Rate (LTIR). At Martin Marietta, safety performance sets the foundation for long term
financial strength and successful execution of our SOAR strategy. We believe this performance is a reflection of the
Company’s Guardian Angel safety culture which encourages each employee to take personal responsibility for working
safely and helping others work safely. That is, to be a good Wingman.
