Approach Resources Inc.

Announces Agreement to Sell Interest in

Southern Midland Basin Oil Pipeline

Fort Worth, Texas, September 19, 2013 – Approach Resources Inc. (NASDAQ: AREX) (together with its subsidiaries, “Approach” or the “Company”) today announced a definitive agreement to sell its interest in an oil pipeline system in the southern Midland Basin for cash proceeds to Approach of $108 million, before taxes and subject to customary post-closing conditions, adjustments and escrows.

Approach, together with its partner in Wildcat Permian Services LLC (“Wildcat”), entered into an Equity Purchase Agreement (the “Agreement”) with affiliates of JP Energy Development LP (together, “JP Energy”), under which JP Energy will acquire all of the equity interests in Wildcat for a purchase price of $210 million, subject to customary post-closing conditions, adjustments and escrows. The transaction is expected to close in late third quarter or early fourth quarter 2013.

Wildcat owns and operates an oil pipeline system consisting of approximately 50 miles of high-pressure, steel pipeline in Crockett and Reagan Counties, Texas, with throughput capacity of 100,000 Bbls/d, truck terminal and LACT bay facilities, multiple receipt points and 40,000 Bbls of crude oil storage. In connection with the acquisition of Wildcat, JP Energy and Approach will enter into a revised crude oil purchase agreement under which JP Energy will purchase and transport the Company’s crude oil production from Crockett and Schleicher Counties, Texas.

J. Ross Craft, the Company’s President and CEO, commented, “The sale of our oil pipeline provides a strong return on our initial investment, further strengthens our liquidity position and continues to provide firm crude oil takeaway from our core operating area. We appreciate the hard work and dedication of the Wildcat team, and look forward to our new partnership with JP Energy and their management team. We believe that JP Energy’s broad, crude oil midstream, transportation and logistics expertise will help us continue to unlock the potential of our Wolfcamp shale oil play.”
