Section 2 – Resource Extraction Issuer Disclosure

Item 2.01 Resource Extraction Issuer Disclosure and Report

Disclosure of Payments by Resource Extraction Issuers

The resource extraction payment disclosure for United States Lime & Minerals, Inc. (the “Company”) required by this Item 2.01 is included as Exhibit 2.01 and Exhibit 99.1 to this Form SD.

Company Operations

The Company, a Texas corporation headquartered in Dallas, Texas, is a manufacturer of lime and limestone products. Through its wholly owned subsidiaries, the Company extracts high-quality limestone from its open-pit and underground mines that it sells as crushed limestone or processes further to produce several higher-value lime and limestone products, including pulverized limestone, quicklime, hydrated lime, and lime slurry.

The Company has one reportable business segment: Lime and Limestone Operations. All of the Company’s Lime and Limestone Operations, including production and sale of its lime and limestone products, are conducted in the United States. The Company’s Other operations relate to its natural gas interests, consisting of royalty and non-operated working interests under an oil and gas lease and a drillsite agreement with two separate operators related to the Company’s Johnson County, Texas properties pursuant to which the Company receives payments from the operators for giving them the right to explore for and extract natural gas and other petroleum products.

Company Resource Extraction Payments

The Company is subject to United States federal corporate income tax on the net income that it earns from its Lime and Limestone Operations and its Other operations, and any other net income it earns. The Company files a consolidated U.S. federal corporate income tax return at the parent entity level for itself and its wholly owned subsidiaries. During its fiscal year ended December 31, 2023, the Company paid, on a cash basis in U.S. dollars, $17.3 million in U.S. federal corporate income tax. The Company made no other payments during 2023 required to be disclosed in this Report.

All of the Company’s U.S. federal corporate income tax payments in 2023 related to its consolidated taxable income. It is not possible to determine what portion of such tax payments were attributable to taxable income the Company earned from the extraction of limestone and the production and sale of crushed limestone as opposed to its production and sale of higher-value lime and limestone products and other operations.
