 an interest is owned. Net wells are calculated based on our net royalty interest, factoring in both ownership percentage of gross wells and royalty rate. The majority of our producing mineral and royalty interest acreage now, or in the future, can be pooled with third-party acreage to form pooled units. Pooling proportionately reduces our royalty interest in wells drilled in a pooled unit, and it proportionately increases the number of wells in which we have such reduced royalty interest. The following table includes our estimate of acreage for oil and gas mineral interests, NPRIs, and ORRIs: December 31, 2024 December 31, 2023 Gross Acres Net Royalty Acres Gross Acres Net Royalty Acres Appalachia 34,661 36,199 34,661 36,199 Gulf Coast 27,932 20,105 27,932 20,105 Permian 121,437 4,568 120,636 4,556 Rockies 13,233 659 326 72 Williston 1,194 2,388 1,194 2,388 Total 198,457 63,919 184,749 63,320 We may own more than one type of interest in the same tract of land, but the overlap is not significant. Net royalty acres are calculated based on our ownership and royalty rate, normalized to a standard 1/8th royalty lease, and assumes a 1/4th royalty rate for unleased acres. 44
