COMPANY OVERVIEW

Raccoon River Sand, one of the Central Division’s top performing locations, is located in Des Moines, Iowa.

Bender said a key reason Raccoon River was able to earn the award in consecutive years is because its team members take
safety seriously and personally. “They ensure that people who join the team know the expectations and ensure people are
using the correct tools to complete tasks. This includes SLAMs, workplace exams, pre-shifts and observations,” he said.
“This shows the team’s commitment level and care for each other.”

When Todd Clock, regional vice president-general manager, heard Raccoon River had earned the award again, he was
amazed. “It’s humbling to receive this award once; however, back-to-back is an honor that is challenging to put into
words, and it speaks loudly to the team’s commitment to working safely,” he said.

Clock added that this sort of achievement illustrates the power of Martin Marietta’s companywide safety culture. “I
believe our commitment to the Guardian Angel Creed and being a Great Wingman has evolved into a culture that is not
found at other companies, and it empowers people to do the right thing all of the time – even when others are not
present or looking,” Clock said.

But Raccoon River is not the only site celebrating an NMA win. The Southwest Division’s Midlothian Cement was awarded
the second Sentinels of Safety Award Martin Marietta won this year.

“I was thrilled when I heard our employees had won the award. The crew at Midlothian Cement is always raising the bar
on safety here,” said Don Cribbs, safety manager. This is the first time the site has won the award in almost four decades.

“We have employees who have been at this plant for a long, long time. Some have been here 40, even 50 years. Many
were here the last time we won this same award in 1984,” he said, “They’ll tell you our goal is to always get better and
better as part of our continuous improvement process.”
