Approach Resources Inc. INVESTOR PRESENTATION MARCH 2013 Exhibit 99.1

Forward-Looking Statements 2 Cautionary Statements Regarding Oil & Gas Quantities This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included in this presentation that address activities, events or developments that the Company expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this presentation specifically include the expectations of management regarding plans, strategies, objectives, anticipated financial and operating results of the Company, including as to the Company’s Wolfcamp shale resource play, estimated resource potential and recoverability of the oil and gas, estimated reserves and drilling locations, capital expenditures, typical well results and well profiles, type curve, and production and operating expenses guidance included in the presentation. These statements are based on certain assumptions made by the Company based on management's experience and technical analyses, current conditions, anticipated future developments and other factors believed to be appropriate and believed to be reasonable by management. When used in this presentation, the words “will,” “potential,” “believe,” “intend,” “expect,” “may,” “should,” “anticipate,” “could,” “estimate,” “plan,” “predict,” “project,” “target,” “profile,” “model” or their negatives, other similar expressions or the statements that include those words, are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. In particular, careful consideration should be given to the cautionary statements and risk factors described in the Company's most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. Any forward-looking statement speaks only as of the date on which such statement is made and the Company undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. The Securities and Exchange Commission (“SEC”) permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that meet the SEC’s definitions for such terms, and price and cost sensitivities for such reserves, and prohibits disclosure of resources that do not constitute such reserves. The Company uses the terms “estimated ultimate recovery” or “EUR,” reserve or resource “potential,” and other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC’s rules may prohibit the Company from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved, probable and possible reserves and accordingly are subject to substantially greater risk of being actually realized by the Company. EUR estimates, identified drilling locations and resource potential estimates have not been risked by the Company. Actual locations drilled and quantities that may be ultimately recovered from the Company’s interest may differ substantially from the Company’s estimates. There is no commitment by the Company to drill all of the drilling locations that have been attributed these quantities. Factors affecting ultimate recovery include the scope of the Company’s ongoing drilling program, which will be directly affected by the availability of capital, drilling and production costs, availability of drilling and completion services and equipment, drilling results, lease expirations, regulatory approval and actual drilling results, as well as geological and mechanical factors Estimates of unproved reserves, type/decline curves, per well EUR and resource potential may change significantly as development of the Company’s oil and gas assets provides additional data. Type/decline curves, estimated EURs, resource potential, recovery factors and well costs represent Company estimates based on evaluation of petrophysical analysis, core data and well logs, well performance from limited drilling and recompletion results and seismic data, and have not been reviewed by independent engineers. These are presented as hypothetical recoveries if assumptions and estimates regarding recoverable hydrocarbons, recovery factors and costs prove correct. The Company has very limited production experience with these projects, and accordingly, such estimates may change significantly as results from more wells are evaluated. Estimates of resource potential and EURs do not constitute reserves, but constitute estimates of contingent resources which the SEC has determined are too speculative to include in SEC filings. Unless otherwise noted, IRR estimates are before taxes and assume NYMEX forward-curve oil and gas pricing and Company-generated EUR and decline curve estimates based on Company drilling and completion cost estimates that do not include land, seismic or G&A costs.

Adjusted Net Income (unaudited) 25 The amounts included in the calculation of adjusted net income and adjusted net income per diluted share below were computed in accordance with GAAP. We believe adjusted net income and adjusted net income 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 income for the three months and year ended December 31, 2012 and 2011, respectively (in thousands, except per-share amounts). (in thousands, except per-share amounts) Year Ended December 31, 2012 2011 Net income $ 6,384 $ 7,242 Adjustments for certain items: Impairment — 18,476 Unrealized (gain) loss on commodity derivatives (3,874) 347 Gain on sale of oil & gas properties — (248) Related income tax effect 1,317 (6,316) Adjusted net income $ 3,827 $ 19,501 Adjusted net income per diluted share $ 0.11 $ 0.67

EBITDAX (unaudited) 26 (in thousands, except per-share amounts) Year Ended December 31, 2012 2011 Net income $ 6,384 $ 7,242 Exploration 4,550 9,546 Impairment — 18,476 Depletion, depreciation and amortization 60,381 32,475 Share-based compensation 7,465 4,683 Unrealized (gain) loss on commodity derivatives (3,874) 347 Gain on sale of oil & gas properties — (248) Interest expense, net 4,737 3,402 Income tax provision 3,338 3,488 EBITDAX $ 82,981 $ 79,411 EBITDAX per diluted share $ 2.37 $ 2.72 We define EBITDAX as net income, plus (1) exploration expense, (2) impairment expense, (3) depletion, depreciation and amortization expense, (4) share- based compensation expense, (5) unrealized (gain) loss on commodity derivatives, (6) gain on sale of oil and gas properties, (7) interest expense and (8) 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 income for the three months and year ended December 31, 2012 and 2011, respectively (in thousands, except per-share amounts).

Liquidity 27 Liquidity (unaudited) is calculated by adding the net funds available under our revolving credit facility and cash and cash equivalents. We use liquidity as an indicator of the Company’s ability to fund development and exploration activities. Liquidity has limitations, and can vary from year to year for the Company and can vary among companies based on what is or is not included in the measurement on a company’s financial statements. Liquidity 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. (in thousands) December 31, 2012 Long-term debt $ 106,000 Total stockholders’ equity 633,468 739,468 Long-term debt-to-capital 14.3% (in thousands) December 31, 2012 Borrowing base $ 280,000 Cash and cash equivalents 767 Long-term debt (106,000) Unused letters of credit (325) Liquidity $ 174,442 debt (GAAP). 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. Long-term debt-to-capital ratio (unaudited) is calculated by dividing long-term debt (GAAP) by the sum of total stockholders’ equity (GAAP) and long-term

F&D Costs Reconciliation (unaudited) 28 We believe that providing measures of finding and development, or F&D, cost is useful to assist an evaluation of how much it costs the Company, on a per Boe basis, to add proved reserves. 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. Due to various factors, including timing differences, F&D costs do not necessarily reflect precisely the costs associated with particular reserves. For example, exploration costs may be recorded in periods before the periods in which related increases in reserves are recorded and development costs may be recorded in periods after the periods in which related increases in reserves are recorded. In addition, changes in commodity prices can affect the magnitude of recorded increases (or decreases) in reserves independent of the related costs of such increases. As a result of the above factors and various factors that could materially affect the timing and amounts of future increases in reserves and the timing and amounts of future costs, including factors disclosed in our filings with the SEC, we cannot assure you that the Company’s future F&D costs will not differ materially from those set forth above. Further, the methods we use to calculate F&D costs may differ significantly from methods used by other companies to compute similar measures. As a result, our F&D costs may not be comparable to similar measures provided by other companies. The following tables reflect the reconciliation of our estimated finding and development costs to the information required by paragraphs 11 and 21 of ASC 932-235. 2012 Reserve summary (MBoe) Balance – 12/31/2011 76,975 Extensions & discoveries 38,861 Revisions (17,469) Production (2,888) Balance – 12/31/2012 95,479 Cost summary ($M) Acquisition costs $ 7,742 Exploration costs 4,550 Development costs 285,039 Total 297,331 Finding & development costs ($/Boe) All-in F&D costs $ 13.90 Drill-bit F&D cost $ 7.45 Reserve replacement ratio (%) Extensions & discoveries (MBoe) 38,861 2012 Production (MBoe) (2,888) Reserve replacement 1,346% 3-Year Reserve summary (MBoe) Balance – 12/31/2009 36,488 Extensions & discoveries 68,182 Purchases 12,456 Revisions (14,866) Production (6,781) Balance – 12/31/2012 95,479 Cost summary ($M) Acquisition costs $ 131,189 Exploration costs 17,415 Development costs 524,476 Total 673,080 Finding & development costs ($/Boe) 3-YR All-in F&D costs $ 10.23 3-YR Drill-bit F&D cost $ 7.95 Reserve replacement ratio (%) Extensions & discoveries (MBoe) 68,182 3-YR Production (MBoe) (6,781) Reserve replacement 1,005%
