The fair market value of the Assigned Royalty Interests was not determined in 1888 when the Trust was formed and, therefore, no value is assigned to these interests on our Consolidated Balance Sheets. Royalty interests acquired represent royalty interests in proved and unproved oil and gas properties. 20 Table of Contents The following table shows NRA in the Assigned Royalty Interests and the royalty interests acquired by county as of December 31, 2025 (1) : Assigned Royalty Interests Royalty Interests Acquired Total County 1/128th NPRI Number of NRA 1/16th NPRI Number of NRA Number of NRA Number of NRA Borden 33 33 Callahan 40 40 Coke 591 591 Crane 17 2,599 2,616 Culberson 55,756 5,014 60,770 Ector 2,102 5,896 79 8,077 Eddy (2) 54 54 Fisher 160 160 Gaines 28 28 Glasscock 225 5,555 2,876 8,656 Howard 194 920 4,530 5,644 Hudspeth 504 504 Jeff Davis 3,778 3,778 Lea (2) 98 98 Loving 382 24,033 390 24,805 Martin 8,364 8,364 Midland 809 6,560 4,319 11,688 Mitchell 110 293 403 Nacogdoches 4 4 Nolan 155 1,579 1,734 Palo Pinto 400 400 Pecos 20 8,448 487 8,955 Presidio 1,600 1,600 Reagan 385 637 1,573 2,595 Reeves 188 58,346 1,897 60,431 Stephens 176 80 256 Sterling 40 1,040 1,080 Taylor 483 483 Upton 431 4,551 2,451 7,433 Ward 1,144 1,144 Winkler 74 1,520 39 1,633 Total 5,308 185,369 33,380 224,057 (1) Counties are located in the State of Texas unless otherwise noted.
