PermRock Royalty Trust

Declares Monthly Cash Distribution

FORT WORTH, Texas, September 20, 2021 – PermRock Royalty Trust (NYSE:PRT) (the “Trust”) today declared a monthly cash distribution to record holders of its trust units representing beneficial interests in the Trust (“Trust Units”) as of September 30, 2021 and payable on October 15, 2021 in the amount of $609,618.80 ($0.050109 per Trust Unit), based principally upon production during the month of July 2021.

The following table displays underlying oil and natural gas sales volumes and average received wellhead prices attributable to the current and prior month net profits interest calculations:

Oil cash receipts for the properties underlying the Trust totaled $2.11 million for the current month, a decrease of $0.03 million from the prior month’s distribution period.  This decrease was due to a slight decrease in sales volumes.

Natural gas cash receipts for the properties underlying the Trust totaled $0.19 million for the current month, an increase of $0.04 million from the prior month’s distribution period. This increase was due to an increase in natural gas prices and sales volume.

Total direct operating expenses, including marketing, lease operating expenses and workover expenses, were $0.70 million reflecting a $0.21 million increase from the prior month. Severance and ad valorem taxes were essentially unchanged from the prior month, totaling $0.17 million.

Capital expenditures were $0.53 million, an increase of $0.06 million from the prior month.  Boaz Energy indicated the capital expenditures were primarily related to drilling and completion operations in Crane and Glasscock counties. Boaz Energy informed the Trust that this month’s net profits calculation included the application of $60,000 net to the Trust of funds previously reserved by Boaz Energy to cover capital obligations and expenses.

These forward-looking statements include the amount and date of any anticipated distribution to unitholders, future cash retentions, advancements or recoupments from distributions, and statements regarding Boaz Energy’s operations and the resulting impact on the computation of the Trust’s net profits. The amount of cash received or expected to be received by the Trust (and its ability to pay distributions) has been and will continue to be directly affected by volatility in commodity prices, oversupply and the economic effects of the COVID-19 pandemic. Further, low oil and natural gas prices may result in no distributions to unitholders in certain periods. Other important factors that could cause actual results to differ materially from those projected in the forward-looking statements include expenses of the Trust and reserves for anticipated future expenses, uncertainties in estimating the cost of drilling activities and risks associated with drilling and operating oil and natural gas wells.
