PermRock Royalty Trust

Declares Monthly Cash Distribution

DALLAS, Texas, September 18, 2026 – 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, 2026, and payable on October 15, 2026, in the amount of $238,742.30 ($0.0196242 per Trust Unit), based principally upon production during the month of July 2026.

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 $1.25 million for the current month, a decrease of $0.17 million from the prior month’s distribution period. T2S Permian Acquisition II LLC (“T2S”) informed the Trust that this decrease was primarily due to decreases in oil sales prices and oil sales volumes. Natural gas cash receipts for the properties underlying the Trust totaled $0.02 million for the current month, an increase of approximately $0.01 million from the prior month’s distribution period, primarily due to an increase in natural gas sales prices. Other revenue totaled $0.11 million for the current month, including salt water disposal income, which was previously reflected as an offset to lease operating expenses and, beginning this month, will instead be presented as other revenue.

Total direct operating expenses, including marketing, lease operating expenses, and workover expenses, were $0.66 million, essentially unchanged from the prior month’s distribution period.

Severance and ad valorem taxes included in this month’s net profits calculation were $0.06 million, a decrease of approximately $0.01 million from the prior month’s distribution period. T2S informed the Trust that this decrease was primarily due to a decrease in severance taxes.

Capital expenditures were $116,596 for the current month. T2S informed the Trust that this amount primarily reflected tangible completion costs, including approximately $51,000 of plugging costs

and $63,000 of capital workover costs, as well as intangible completion costs, partially offset by a credit to tangible drilling costs.

T2S informed the Trust that this month’s net profits calculation included a net release of $62,500 from funds previously reserved by T2S, consisting of a $125,000 release of funds previously held for workovers, partially offset by a $62,500 holdback for future ad valorem taxes.
