Exhibit 95.1
MINE SAFETY DISCLOSURES
We operate aggregate mines that are subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977, 30 U.S.C. § 801 et seq. (the “Mine Act”). Set forth below is the required information regarding certain mining safety and health matters for the year ended December 31, 2025. Citations and orders may be contested and appealed, and in that process, may be reduced in severity and amount, and are sometimes dismissed. The table below includes references to specific sections of the Mine Act.
The information in the table below is presented by mine, consistent with the manner in which we maintain safety and compliance information about our mining operations.
