UNITED STATES LIME & MINERALS INC

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC. The operation of the Company’s quarries, underground mine, and plants is subject to regulation by MSHA. The required information regarding certain mining safety and health matters, broken down by mining complex, for the year ended December 31, 2023 is presented in Exhibit 95.1 to this Report on Form 10-K.

As discussed in Item 1 above, the Company believes it is responsible to employees to provide a safe and healthy workplace environment. The Company seeks to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety standards and establishing and improving safe work practices; involving employees in safety processes; and recording, reporting, and investigating accidents, incidents, and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar penalties assessed for citations and orders issued in recent years.
