Permian Basin Royalty Trust

PERMIAN BASIN ROYALTY TRUST

ANNOUNCES AUGUST CASH DISTRIBUTION

DALLAS, Texas, August 19, 2014 – Permian Basin Royalty Trust (NYSE: PBT) (“Permian”) today declared a cash distribution to the holders of its units of beneficial interest of $0.109382 per unit, payable on September 15, 2014, to unit holders of record on August 29, 2014.

This month’s distribution decreased from the previous month due to one less day of oil production for June 2014, offset by one more day of gas production for May 2014, and an increase in oil prices.

Production for the Trust’s allocated portion of the Waddell Ranch and the Texas Royalty Properties combined for oil and gas respectively was 50,457 bbls and 112,187 Mcf. The average price for oil was $96.40 per bbl and for gas was $6.45 per Mcf. This would primarily reflect production for the month of June for oil and the month of May for gas. The worldwide market conditions continue to affect the pricing for domestic production. It is difficult to predict what effect these conditions will have on future distributions.

Capital expenditures were approximately $1,325,441.57. The numbers provided reflect what was net to the Trust.

The Trustee continues to evaluate the claim of $4,542,547 overpayment that was recouped by ConocoPhillips back in September and October 2011. The accounting adjustments and subsequent reimbursements of this claim have been processed through the monthly distributions. These prior period adjustments along with the respective reimbursements of the withheld monies have been completed as of last month, however, these adjustments will continue to be reviewed for accuracy and validity through the 2014 audit period.
