PERMIAN BASIN ROYALTY TRUST

ANNOUNCES LAWSUIT AGAINST BLACKBEARD OPERATING, LLC

DALLAS, Texas, May 8, 2024 – Argent Trust Company, as Trustee of the Permian Basin Royalty Trust (NYSE: PBT) (“Permian” or the “Trust”) today announced that it has initiated a lawsuit by filing a petition in the District Court of Tarrant County, Texas against Blackbeard Operating, LLC (“Blackbeard”), the operator of properties in the Waddell Ranch, in Crane County, Texas, in which the Trust holds a 75% net overriding royalty.

Pursuant to the petition, the Trustee seeks to recover more than $15 million in damages to the Trust resulting from overhead costs and other expenses the Trustee alleges were impermissibly deducted from royalty payments to the Trust. The Trustee routinely engages in audits of the revenues and expenses with respect to the Trust’s royalty payments. In connection with its audit for the period from 2020-2022 the Trustee identified exceptions to certain expenses deducted from the Trust’s royalty payments, including among other things, incorrect overhead charges, application of overhead charges to non-producing wells, duplicate charges for services, materials, and utilities, as well as other expenses the Trustee alleges are ineligible charges. Attempts to resolve the disputed charges outside of court have been unsuccessful to date.
