The Company&#8217;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&#8217;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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><i style="font-style:italic;">Company Resource Extraction Payments</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;">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, 2024, the Company paid, on a cash basis in U.S. dollars, $29.6 million in U.S. federal corporate income tax. The Company made no other payments during 2024 required to be disclosed in this Report.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;">All of the Company&#8217;s U.S. federal corporate income tax payments in 2024 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
