WORLD-CLASS SAFETY PERFORMANCE

Our companywide safety performance, inclusive of our more recently acquired operations, continues to deliver near or
better than world-class safety levels. In 2019, 90 percent of our business units worked without a reportable incident, and
98 percent of our business units worked without a lost-time incident; the resulting overall lost-time incident rate of 0.20
is impressive by any standard. We strengthened our Guardian Angel safety culture by achieving a world-class lost-time
incident rate for the third consecutive year. Additionally, we reduced total reportable cases and lost-time incidents by 62
percent and 83 percent, respectively, at our legacy Bluegrass Materials operations acquired in 2018.

MSHA CITATIONS
The United States Department of Labor’s Mine Safety and Health Administration (MSHA) inspects each surface mine at
