News Release

Approach Resources Inc.
Reports Results for Second Quarter 2009

     Fort Worth, Texas, August 4, 2009 — Approach Resources Inc. (NASDAQ: AREX) today reported second quarter 2009 financial and operating results.

Highlights

     Highlights for the second quarter of 2009 (compared to second quarter of 2008) include:

• Production increased 12% to 2.3 Bcfe (25.1 MMcfe/d)

• Production was 71% natural gas and 29% oil and NGLs, compared to 82% natural gas and 18% oil and NGLs in the second quarter of 2008

• Revenues decreased 59% to $9.9 million, on a 63% drop in average realized commodity prices (before the effect of commodity derivatives) to $4.35 per Mcfe and a 46% drop in average realized commodity prices (after the effect of commodity derivatives) to $6.30 per Mcfe

• Net loss was $671,000, or $(0.03) per diluted share, compared to net income of $928,000, or $0.04 per diluted share, for the second quarter of 2008, a 172% decrease

• Adjusted net income (a non-GAAP measure) was $2.2 million, or $0.10 per diluted share, a 70% decrease

• EBITDAX (a non-GAAP measure) was $10.2 million, or $0.49 per diluted share, a 46% decrease

Second Quarter 2009 Results

     Production for the second quarter of 2009 totaled 2.3 Bcfe (25.1 MMcfe/d), compared to 2.0 Bcfe (22.4 MMcfe/d) produced in the second quarter of 2008, an increase of 12%. Production decreased 10% in the second quarter of 2009, compared to first quarter 2009 production of 2.5 Bcfe. Second quarter 2009 production was 71% natural gas and 29% oil and NGLs, compared to 82% natural gas and 18% oil and NGLs in the second quarter of 2008.

     Revenues for the second quarter of 2009 totaled $9.9 million, compared to revenues of $24.1 million for the second quarter of 2008. Revenues for the second quarter of 2009 were negatively impacted by a sharp decline in realized commodity prices over the prior year quarter. Average realized natural gas, oil and NGL prices for the second quarter of 2009, before the effect of commodity derivatives, were $3.28 per Mcf, $55.60 per Bbl and $26.84 per Bbl, respectively, versus $11.10 per Mcf, $121.29 per Bbl and $53.93 per Bbl, respectively, for the second quarter of 2008. The Company’s average realized price, including the effect of commodity derivatives, was $6.30 per Mcfe for the second quarter of 2009, compared to $11.59 per Mcfe for the second quarter of 2008, a decrease of 46%. Of the

$14.2 million decrease in revenues, approximately $16.0 million was attributable to a decrease in oil and gas prices, which was partially offset by approximately $1.8 million attributable to an increase in production from Cinco Terry.

     Net loss for the second quarter of 2009 was $671,000, or $(0.03) per diluted share, compared to net income of $928,000, or $0.04 per diluted share, for the second quarter of 2008. Net loss for the second quarter of 2009 included a pre-tax, unrealized loss on commodity derivatives of $4.3 million.

     Excluding the unrealized loss on commodity derivatives and related income taxes, adjusted net income (a non-GAAP measure) for the second quarter of 2009 was $2.2 million, or $0.10 per diluted share, compared to adjusted net income of $7.3 million, or $0.35 per diluted share, for the second quarter of 2008. See “Supplemental Non-GAAP Financial and Other Measures” below for our reconciliation of adjusted net income to net income.

     EBITDAX (a non-GAAP measure) for the second quarter of 2009 was $10.2 million, or $0.49 per diluted share, compared to $19.0 million, or $0.91 per diluted share, for the second quarter of 2008. See “Supplemental Non-GAAP Financial and Other Measures” below for our reconciliation of EBITDAX to net income.

     Lease operating expenses (“LOE”) for the second quarter of 2009 were $1.8 million ($0.77 per Mcfe), compared to $1.9 million ($0.91 per Mcfe) in the second quarter of 2008. The decrease in LOE over the prior year period was due in part to lower expenses related to well repair and maintenance costs as well as a $235,000 reduction of our estimated ad valorem tax accrual for the three months ended March 31, 2009, which we recognized during the second quarter of 2009.

     Severance and production taxes for the second quarter of 2009 were $507,000, or 5.1% of oil and gas sales, compared to $1.2 million, or 4.8% of oil and gas sales, in the second quarter of 2008.

     General and administrative (“G&A”) expenses for the second quarter of 2009 were $2.2 million ($0.98 per Mcfe), compared to $1.8 million ($0.89 per Mcfe) for the second quarter of 2008. The increase in G&A expenses was principally due to increased staffing, share-based compensation and an increase in franchise taxes partially due to the timing of payment compared to 2008.

     Depletion, depreciation and amortization (“DD&A”) expenses for the second quarter of 2009 were $6.2 million ($2.73 per Mcfe), compared to $6.0 million ($2.93 per Mcfe) for the second quarter of 2008. The decrease in DD&A expenses per Mcfe was primarily attributable to an increase in our estimated proved reserves partially offset by an increase in production over the prior year quarter.

     Our income tax benefit was $460,000 for the second quarter of 2009. Our provision for income taxes was $804,000 for the second quarter of 2008. Our effective income tax rate for the second quarter of 2009 was 40.7%, compared with 46.4% for the second quarter of 2008.

Capital Expenditures and Drilling Operations

     Capital expenditures for drilling and development in the second quarter of 2009 totaled $3.1 million, and included the completion of seven gross (3.5 net) wells that were waiting on completion at March 31, 2009, all of which were completed as producers. Our estimated average daily net production for the month of July 2009 was 22.8 MMcfe/d.

     As previously announced, due to the continued weakness in commodity prices, we did not extend the contracts for our two remaining drilling rigs after March 31, 2009, and we released these rigs during the first week of April 2009. We currently expect that our capital expenditures for the year ending

2

December 31, 2009 will not exceed $25 million. We intend to fund our 2009 capital expenditures with internally-generated cash flows, with any excess cash flows applied to debt, working capital obligations or strategic acquisitions. Our capital expenditure budget is subject to change depending upon a number of factors, including economic and industry conditions at the time of drilling, prevailing and anticipated prices for oil and gas, the results of our development and exploration efforts, the availability of sufficient capital resources to us and other participants for drilling prospects, our financial results, the availability of leases on reasonable terms and our ability to obtain permits for the drilling locations.

Liquidity and Commodity Derivatives Update

     We have a $200 million revolving credit facility with a $100 million borrowing base, of which $46.2 million and $42.9 million were drawn at June 30, 2009 and July 31, 2009, respectively. As of June 30, 2009, our long-term debt-to-capital ratio (a non-GAAP measure) was 17%. See “Supplemental Non-GAAP Financial and Other Measures” below for our definition of “long-term debt-to-capital ratio.”

     As of July 31, 2009, we had the following commodity derivatives positions outstanding:

Management Comments

     J. Ross Craft, the Company’s President and Chief Executive Officer, commented “The significant decline in natural gas prices continued to affect our revenues and net income during the second quarter of 2009. We do not anticipate an appreciable improvement in natural gas pricing for the remainder of 2009 and have increased our 2010 hedge position through two fixed price swaps with an average price of $6.13 per MMBtu. However, we remain positive on the long-term outlook for natural gas, a clean, abundant fuel source.

     “We continue to be a low-cost operator and have implemented several cost-saving measures in the field that contributed to a reduction in operating expenses over both the prior-year quarter and the past quarter. The reduction in operating expenses, along with the continued reduction in service costs, helped offset current commodity prices. We plan to resume our Cinco Terry drilling program, where we can benefit from higher oil and natural gas liquids production, during the fourth quarter of 2009. We have restarted the permitting process for a 106-square mile 3-D seismic shoot over Cinco Terry and expect data collection to begin in January 2010. When completed, we should be able to high grade Ellenburger, Canyon and Wolfcamp targets. We also continue to focus on optimizing our Ozona Northeast asset base through low-cost, high-return projects. We have identified several Strawn and Ellenburger deepening projects as a result of our reprocessed 3-D seismic data and are currently on our first well of a four-well test program.”

Supplemental Non-GAAP Financial and Other Measures

     This release contains certain financial measures that are non-GAAP measures. We have provided reconciliations within this release of the non-GAAP financial measures to the most directly comparable GAAP financial measures here and on the Non-GAAP Financial Information page in the Investor Relations section of our website at www.approachresources.com.

Adjusted Net Income

     This release contains the non-GAAP financial measures adjusted net income and adjusted earnings per diluted share, which exclude the unrealized, pre-tax loss on commodity derivatives and related income taxes.

     The amounts included in the calculation of adjusted net income and adjusted earnings per diluted share below were computed in accordance with GAAP. We believe adjusted net income and adjusted earnings per diluted share are useful to investors because they provide readers with a more meaningful measure of our profitability before recording certain items whose timing or amount cannot be reasonably determined. However, these measures are provided in addition to, and not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP (including the notes), included in our SEC filings and posted on our website.

     The following table provides a reconciliation of adjusted net income to net (loss) income for the three and six months ended June 30, 2009 and 2008, respectively (in thousands, except per-share metrics):

Adjusted earnings per diluted share	$	0.10		$	0.35		$	0.08		$	0.64

EBITDAX

     We define EBITDAX as net (loss) income, plus (1) exploration expense, (2) depletion, depreciation and amortization expense, (3) share-based compensation expense, (4) unrealized loss on commodity derivatives, (5) interest expense and (6) income taxes. EBITDAX is not a measure of net income or cash flow as determined by GAAP. The amounts included in the calculation of EBITDAX were computed in accordance with GAAP. EBITDAX is presented herein and reconciled to the GAAP measure of net income because of its wide acceptance by the investment community as a financial indicator of a company’s ability to internally fund development and exploration activities. This measure is provided in addition to, and not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP (including the notes), included in our SEC filings and posted on our website.

     The following table provides a reconciliation of EBITDAX to net (loss) income for the three and six months ended June 30, 2009 and 2008, respectively (in thousands, except per-share metrics):

Long-Term Debt-to-Capital Ratio

     Long-term debt-to-capital ratio is calculated as of June 30, 2009, and by dividing long-term debt (GAAP) of $46.2 million by the sum of total stockholders’ equity (GAAP) and long-term debt (GAAP) of $271.3 million. We use the long-term debt-to-capital ratio as a measurement of our overall financial leverage. However, this ratio has limitations. This ratio can vary from year to year for the Company and can vary among companies based on what is or is not included in the ratio on a company’s financial statements. This ratio is provided in addition to, and not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP (including the notes), included in our SEC filings and posted on our website.
