Declares Monthly Cash Distribution

FORT WORTH, Texas, August 21, 2018 – 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 August 31, 2018 and payable on September 17, 2018 in the aggregate amount of $1,126,088.54 or $0.092562 per Trust Unit, based principally upon production during the month of June 2018.

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:

	Underlying Sales Volumes								Average Price
	Oil				Natural Gas				Oil (per Bbl)		Natural Gas (per Mcf)
	Bbls		Bbls/D		Mcf		Mcf/D
Current Month		47,134		1,571		58,601		1,953	$	56.45	$	4.29
Prior Month		48,664		1,570		62,590		2,019	$	62.96	$	3.86

Oil cash receipts for the properties underlying the Trust totaled $2.66 million for the current month, a decrease of $0.40 million from the prior month distribution period as a result of a reduction in sales volumes and oil prices compared to the prior month. Boaz Energy advised the Trustee that the reduction in sales volumes is primarily attributable to the shortened production month and the reduction in sales price was primarily attributable to an increase in the regional differentials to NYMEX, primarily the Midland Cushing differential and the West Texas Sour differential.

Despite a decrease in natural gas sales volumes, natural gas cash receipts increased slightly from $0.24 million in the prior distribution period to $0.25 million in the current month due to the increased gas prices.    Boaz Energy advised the Trustee that the decrease in sales volumes was primarily attributable to the shorter month along with lower sales volumes in Crane County due to high sales line pressure and downtime at the third-party gas processing plant.

Total direct operating expenses, including lease operating expenses and workover expenses, were $0.60 million, an increase of $0.08 million from the prior month. Severance and ad valorem taxes were $0.22 million.

Capital expenditures were $0.49 million in the current month. Boaz Energy advised the Trustee that capital expenditures were primarily attributable to the drilling program fornon-operated wells in Crane and Ward Counties along withnon-operated recompletion projects in Glasscock County, and that due to the success of both programs, Boaz has increased its capital budget for the second half of 2018 to $1.2 million to continue the development programs.
