Estimated second quarter 2012 production totaled 702 MBoe (7.7 MBoe/d),
compared to 608 MBoe (6.7 MBoe/d) produced in second quarter 2011, a 16%
increase. Estimated second quarter 2012 production increased 7%, compared to
first quarter 2012 production of 654 MBoe (7.2 MBoe/d). Estimated oil
production for second quarter 2012 increased 120% to 230 MBbls, compared to
104 MBbls produced in second quarter 2011, and increased 20% compared to first
quarter 2012 oil production of 191 MBbls. Estimated production for second
quarter 2012 was 33% oil, 32% NGLs and 35% natural gas, compared to 17% oil,
39% NGLs and 44% natural gas in second quarter 2011.

Preliminary, average realized prices for second quarter 2012, before the
effect of commodity derivatives, were $83.21 per Bbl of oil, $33.75 per Bbl of
NGLs and $2.19 per Mcf of natural gas, compared to $97.89 per Bbl of oil,
$51.88 per Bbl of NGLs and $4.16 per Mcf of natural gas for second quarter
2011. Our preliminary, average realized price, including the effect of
commodity derivatives, was $43.12 per Boe for second quarter 2012, compared to
$48.01 per Boe for second quarter 2011.

Preliminary, unaudited estimates of capital expenditures during second quarter
2012 totaled $70.3 million, and included $65.1 million for exploration and
development drilling, $4.6 million for pipeline and infrastructure projects
and $600,000 for acreage acquisitions. During second quarter 2012, the Company
drilled seven wells and completed 10 wells, including eight of 11 wells that
were waiting on completion at March 31, 2012. At June 30, 2012, we had eight
wells waiting on completion, of which five have since been completed as
producers and one has been completed as a water source well. We also
recompleted 14 wells during the second quarter of 2012.

Proved Reserves Update

Estimated proved reserves at June 30, 2012, were 83.7 MMBoe, an increase of 9%
and 25% over year-end 2011 and mid-year 2011 proved reserves, respectively.
Oil proved reserves at June 30, 2012, were 23.5 MMBbls, an increase of 30% and
132% over year-end 2011 and mid-year 2011 oil proved reserves, respectively.
The Company’s proved reserves were 28% oil, 36% NGLs and 36% natural gas at
June 30, 2012, compared to 23% oil, 38% NGLs and 39% natural gas at year-end
2011. Reserve growth for the first half of 2012 was driven by the Company’s
drilling program in Project Pangea targeting the Wolfcamp oil shale and the
Wolffork formations.

The standardized after-tax measure of discounted future net cash flows (the
“Standardized Measure”) for our proved reserves at June 30, 2012, was $447.9
million. The pre-tax present value of our proved reserves discounted at 10%
(“PV-10”), was estimated at $755.2 million. Proved reserves volumes and PV-10
were prepared using prices of $90.13 per Bbl of oil, $50.07 per Bbl of NGLs
and $3.36 per Mcf of natural gas. See “Supplemental Non-GAAP Measure” below
for our definition of PV-10 and reconciliation to the Standardized Measure.

Management Comment

Approach’s President and CEO, J. Ross Craft, commented, “Our oil production
surged in the second quarter to its highest level in our history, jumping 120%
year-over-year as a result of our horizontal development drilling in the
Wolfcamp oil shale. Oil and NGLs now represent 65% of our production mix and
64% of our reserve mix, which is a dramatic turnaround from just three years
ago, when our primary product was natural gas. Beginning in the second half of
the year, we expect to realize the benefit of adding a second horizontal rig
in the southern Midland Basin.”

Approach Resources Inc. is an independent oil and gas company with core
operations, production and reserves located in the Permian Basin in West
Texas. The Company targets multiple oil and liquids-rich formations in the
Permian Basin, where the Company operates approximately 146,000 net acres. The
Company’s estimated proved reserves as of June 30, 2012, total 83.7 million
barrels of oil equivalent, made up of 64% oil and NGLs and 36% natural gas.

Supplemental Non-GAAP Measure

This release contains a financial measure that is a non-GAAP measure. We have
provided the reconciliation below of the non-GAAP financial measure to the
most directly comparable GAAP financial measure and on the Non-GAAP Financial
Information page in the Investor Relations section of our website at
www.approachresources.com.

PV-10

The present value of our proved reserves, discounted at 10% (“PV-10”), was
estimated at $755.2 million at June 30, 2012, and was calculated based on the
first-of-the-month, 12-month average prices for oil, NGLs and gas, of $90.13
per Bbl of oil, $50.07 per Bbl of NGLs and $3.36 per Mcf of natural gas,
respectively.

PV-10 is our estimate of the present value of future net revenues from proved
oil and gas reserves after deducting estimated production and ad valorem
taxes, future capital costs and operating expenses, but before deducting any
estimates of future income taxes. The estimated future net revenues are
discounted at an annual rate of 10% to determine their “present value.” We
believe PV-10 to be an important measure for evaluating the relative
significance of our oil and gas properties and that the presentation of the
non-GAAP financial measure of PV-10 provides useful information to investors
because it is widely used by professional analysts and investors in evaluating
oil and gas companies. Because there are many unique factors that can impact
an individual company when estimating the amount of future income taxes to be
paid, we believe the use of a pre-tax measure is valuable for evaluating the
Company. We believe that PV-10 is a financial measure routinely used and
calculated similarly by other companies in the oil and gas industry.

The following table reconciles PV-10 to our standardized measure of discounted
future net cash flows, the most directly comparable measure calculated and
presented in accordance with GAAP. PV-10 should not be considered as an
alternative to the standardized measure as computed under GAAP.
