Fourth Quarter 2014 Financial Results

For the three months ended December 31, 2014, the Company reported net income from continuing operations attributable to common stockholders of $607 million, or $2.32 per basic and diluted share, compared to a net loss from continuing operations of $225 million in the fourth quarter for 2013.  The GAAP net income for the fourth quarter of 2014 included the following items:

·                  Adjusted EBITDAX of $330 million, a 53% increase compared to $215 million in the fourth quarter of 2013

·                  Cash flow from operations before changes in working capital of $278 million, a 59% increase compared to $174 million in the fourth quarter of 2013

Net production for the fourth quarter of 2014 averaged 1,265 MMcfe/d, an 87% increase as compared to the fourth quarter of 2013 and a 17% increase from the third quarter of 2014.  Net production was comprised of 1,082 MMcf/d of natural gas (86%), 27,174 Bbl/d of natural gas liquids (“NGL”s) (13%) and 3,273 Bbl/d of crude oil (1%).  Fourth quarter 2014 net liquids production (NGLs and oil) of 30,447 Bbl/d increased 172% as compared to the fourth quarter of 2013 and 22% from the third quarter of 2014.

Average natural gas price before hedging decreased 3% from the prior year quarter to $3.66 per Mcf, a $0.34 per Mcf negative differential to Nymex, due to wider Appalachian index basis.  Approximately 64% of Antero’s fourth quarter 2014 natural gas revenue was realized at favorable indices, including Columbia Gas Transmission (TCO), Nymex and Chicago.  The remaining 36% of natural gas production was priced at various less favorable index pricing points, including Dominion South and Tetco M2.

Average realized Y-grade C3+ NGL price for the fourth quarter of 2014 was $33.41 per barrel, or 46% of Nymex WTI oil price, a 40% decrease as compared to the prior year quarter, and average realized oil price before hedging was $59.85 per barrel, a 32% decrease as compared to the fourth quarter of 2013.  Average natural gas-equivalent price including NGLs and oil, but excluding hedge settlements, decreased from the prior year quarter by 9% to $4.00 per Mcfe.

Average realized natural gas price including hedges was $4.39 per Mcf for the fourth quarter of 2014, a 7% decrease as compared to the fourth quarter of 2013.  Average realized oil price including hedges was $78.24 per barrel, a 30% decrease as compared to the fourth quarter of 2013.  Average natural gas-equivalent price including NGLs, oil and hedge settlements decreased by 11% to $4.68 per Mcfe for the fourth quarter of 2014 as compared to the fourth quarter of 2013.  For the fourth quarter of 2014, Antero realized hedging gains of $78 million, or $0.68 per Mcfe.

Total revenues for the fourth quarter of 2014 were $1.5 billion as compared to $480 million for the fourth quarter of 2013.  Revenue for the fourth quarter of 2014 included an $853 million non-cash gain on unsettled hedges while the fourth quarter of 2013 included a $152 million non-cash gain on unsettled hedges. Liquids production contributed 22% of combined natural gas, NGLs and oil revenue before hedges in the fourth quarter of 2014, consistent with the prior year.  Adjusted net revenue increased 78% to $585 million compared to the fourth quarter of 2013 (including cash-settled hedge gains and losses but excluding unsettled hedge gains and losses).  For a reconciliation of adjusted net revenue to operating revenue, the most comparable GAAP measure, please read “Non-GAAP Financial Measures.”

Marketing revenue for the fourth quarter of 2014 was $31 million.  Antero’s marketing revenue was primarily associated with the sale of third-party gas purchased to utilize the Company’s excess firm transportation capacity on the Rockies Express Pipeline.

2

Marketing expense for the fourth quarter of 2014 was $45 million.  The largest components of marketing expense were the costs related to excess capacity, the cost of purchasing third-party gas and the firm transport demand costs associated with the Company’s currently unused ATEX ethane pipeline capacity.

Per unit cash production expense (lease operating, gathering, compression, processing and transportation, and production tax) for the fourth quarter of 2014 was $1.54 per Mcfe which is a 1% increase compared to $1.52 per Mcfe in the prior year quarter.  Per unit general and administrative expense for the fourth quarter of 2014, excluding non-cash equity-based compensation expense, was $0.24 per Mcfe, a 23% decrease from the fourth quarter of 2013.  The decrease was primarily driven by the significant increase in net production.  Per unit depreciation, depletion and amortization expense increased 12% from the prior year quarter to $1.35 per Mcfe, primarily driven by higher depreciation on gathering and fresh water distribution assets as Antero Midstream and Antero continued to build out these respective systems in the rich gas areas of the Marcellus and Utica Shale plays.

Adjusted EBITDAX of $330 million for the fourth quarter of 2014 was 53% higher than the prior year quarter due to increased production and revenue.  EBITDAX margin for the quarter was $2.84 per Mcfe, representing an 18% decrease over the prior year quarter due to lower commodity prices.  For the fourth quarter of 2014, cash flow from operations before changes in working capital increased 59% from the prior year to $278 million.

2014 Financial Results

Net production for 2014 averaged 1,007 MMcfe/d, an increase of 93% from the prior year.  Net production was comprised of 869 MMcf/d of natural gas (86%), 19,458 Bbl/d of NGLs (12%) and 3,593 Bbl/d of crude oil (2%).  Net liquids production in 2014 averaged 23,051 Bbl/d, an increase of 258% over 2013 liquids production.  The net production increase was primarily driven by production from 136 new Marcellus wells and 41 new Utica wells brought on line in 2014, all operated by Antero.

Average natural gas price before hedges increased 5% from the prior year to $4.10 per Mcf, a $0.31 per Mcf negative differential to Nymex.  Approximately 60% of Antero’s 2014 natural gas revenue was realized at favorable indices, including Columbia Gas Transmission (TCO), Nymex and Chicago.  The remaining 40% of natural gas production was priced at various other less favorable index pricing points, including Dominion South and Tetco M2.

Average realized Y-grade C3+ NGL price for 2014 was $46.23 per barrel, or 50% of the Nymex WTI oil price, a 12% decrease as compared to the prior year, and average realized oil price before hedging was $81.65 per barrel, an 11% decrease as compared to the prior year.  Average natural gas-equivalent price including NGLs and oil, but excluding hedge settlements, increased 10% to $4.73 per Mcfe from the prior year.

Average realized natural gas price including hedges was $4.52 per Mcf for 2014, a 6% decrease as compared to 2013.  Average realized oil price including hedges was $84.66 per barrel, a 15% decrease as compared to 2013.  Average natural gas-equivalent price including NGLs, oil and hedge settlements, decreased by 1% to $5.10 per Mcfe for 2014 as compared to 2013.  For 2014, Antero realized hedging gains of $136 million or $0.37 per Mcfe.

Total revenues for 2014 were $2.7 billion as compared to $1.3 billion for the prior year.  Revenue for 2014 included a $732 million non-cash gain on unsettled hedges while 2013 included a $328 million non-cash gain on unsettled hedges.  Liquids production contributed 25% of combined natural gas, NGLs and oil revenue before hedges in 2014 compared to 16% during 2013.  Non-GAAP adjusted net revenue increased 98% to $1.9 billion compared to 2013 (including cash-settled hedge gains and losses but excluding unsettled hedge gains and losses).  For a reconciliation of adjusted net revenue to operating revenue, the most comparable GAAP measure, please read “Non-GAAP Financial Measures.”

Marketing revenue for 2014 was $54 million.  Antero’s marketing revenue was primarily associated with the sale of third-party gas purchased to utilize the Company’s excess firm transportation capacity on the Rockies Express Pipeline.

Marketing expense for 2014 was $103 million.  The largest components of marketing expense were the cost of purchasing third-party gas and the firm transport demand costs associated with the Company’s underutilized ATEX ethane pipeline capacity.

Per unit cash production expense (lease operating, gathering, compression, processing and transportation, and production tax) for 2014 was $1.58 per Mcfe which is an 8% increase compared to $1.46 per Mcfe in the prior year.  The increase was primarily due to the

3

significant increase in liquids production and the associated processing and operating expenses.  Per unit general and administrative expense for 2014, excluding non-cash equity based compensation expense, was $0.28 per Mcfe, a 13% decrease from 2013.  The decrease was primarily driven by the significant increase in net production.  Per unit depreciation, depletion and amortization expense increased 6% from the prior year to $1.30 per Mcfe, primarily driven by increased depreciation on midstream assets and facilities.

Adjusted EBITDAX of $1.2 billion for 2014 was 79% higher than the prior year due to increased production and revenue.  EBITDAX margin for 2014 was $3.16 per Mcfe representing a 7% decrease from the prior year.  For 2014, cash flow from operations before changes in working capital increased 99% from the prior year to $980 million.

The Company reported net income from continuing operations attributable to common stockholders of $671 million ($2.56 per basic and diluted share) on a GAAP basis for 2014, including $732 million of non-cash gains on unsettled hedges ($456 million net of tax), $112 million of non-cash equity-based compensation expense ($101 million net of tax), a $40 million gain on sale of assets ($25 million net of tax), $20 million of losses on early extinguishment of debt ($13 million net of tax) and $15 million of impairment of unproved properties ($9 million net of tax).  Excluding these non-cash items, adjusted net income from continuing operations attributable to common stockholders was $314 million ($1.20 per basic and diluted share) for 2014 representing an 84% increase over the prior year.

Non-GAAP Financial Measures

Adjusted net revenue as set forth in this release represents total operating revenue adjusted for certain non-cash items, including unsettled hedge gains and losses and gains and losses on asset sales.  Antero believes that adjusted net revenue is useful to investors in evaluating operational trends of the Company and its performance relative to other oil and gas producing companies.  Adjusted net revenue is not a measure of financial performance under GAAP and should not be considered in isolation or as a substitute for total operating revenue as an indicator of financial performance.  The following table reconciles total operating revenue to adjusted net revenue:

Adjusted net income from continuing operations attributable to common stockholders as set forth in this release represents net income (loss) from continuing operations attributable to common stockholders, adjusted for certain items.  Antero believes that adjusted net income from continuing operations attributable to common stockholders is useful to investors in evaluating operational trends of the Company and its performance relative to other oil and gas producing companies.  Adjusted net income from continuing operations attributable to common stockholders is not a measure of financial performance under GAAP and should not be considered in isolation or as a substitute for net income (loss) from continuing operations attributable to common stockholders as an indicator of financial performance.  The following table reconciles net income (loss) from continuing operations attributable to common stockholders to adjusted net income from continuing operations attributable to common stockholders:

Cash flow from operations before changes in working capital as presented in this release represents net cash provided by operating activities before changes in working capital.  Cash flow from operations before changes in working capital is widely accepted by the investment community as a financial indicator of an oil and gas company’s ability to generate cash to internally fund exploration and development activities and to service debt.  Cash flow from operations before changes in working capital is also useful because it is widely used by professional research analysts in valuing, comparing, rating and providing investment recommendations of companies in the oil and gas exploration and production industry.  In turn, many investors use this published research in making investment decisions.  Cash flow from operations before changes in working capital is not a measure of financial performance under GAAP and should not be considered in isolation or as a substitute for cash flows from operating, investing, or financing activities, as an indicator of cash flows, or as a measure of liquidity.

The following table reconciles net cash provided by operating activities to cash flow from operations before changes in working capital as used in this release:

The following table reconciles consolidated net debt to total debt as used in this release:

Adjusted EBITDAX is a non-GAAP financial measure that Antero defines as net income (loss) from continuing operations after adjusting for those items shown in the table below.  Adjusted EBITDAX, as used and defined by the Company, may not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in accordance with GAAP.  Adjusted EBITDAX should not be considered in isolation or as a substitute for operating income, net income (loss), cash flows from operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP.  Adjusted EBITDAX provides no information regarding a company’s capital structure, borrowings, interest costs, capital expenditures, and working capital movement or tax position.  Adjusted EBITDAX does not represent funds available for discretionary use because those funds may be required for debt service, capital expenditures, working capital, income taxes, franchise taxes, exploration expenses, and other commitments and obligations.  However, Antero’s management team believes Adjusted EBITDAX is useful to an investor in evaluating the Company’s financial performance because this measure:

·                  is widely used by investors in the oil and gas industry to measure a company’s operating performance without regard to items excluded from the calculation of such term, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired, among other factors;

·                  helps investors to more meaningfully evaluate and compare the results of Antero’s operations from period to period by removing the effect of its capital structure from its operating structure; and

·                  is used by the Company’s management team for various purposes, including as a measure of operating performance, in presentations to its board of directors, as a basis for strategic planning and forecasting and by its lenders pursuant to covenants under its credit facility and the indentures governing the Company’s senior notes.

There are significant limitations to using Adjusted EBITDAX as a measure of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect Antero’s net income (loss), the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted EBITDAX reported by different companies.  The following table represents a reconciliation of the Company’s net income (loss) from continuing operations to Adjusted EBITDAX, a reconciliation of total Adjusted EBITDAX to net cash provided by operating activities and a reconciliation of realized price before cash receipts for settled hedges to EBITDAX margin:

Cautionary Statements

This release includes “forward-looking statements”.  Such forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond Antero’s control. All statements, other than historical facts included in this release, are forward-looking statements.  All forward-looking statements speak only as of the date of this release. Although Antero believes that the plans, intentions and expectations reflected in or suggested by the forward-looking statements are reasonable, there is no assurance that these plans, intentions or expectations will be achieved. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in such statements.

Antero cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the Company’s control, incident to the exploration for and development, production, gathering and sale of natural gas, NGLs and oil. These risks include, but are not limited to, commodity price volatility, inflation, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating natural gas and oil reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures, and the other risks described under the heading “Item 1A. Risk Factors” in Antero’s Annual Report on Form 10-K for the year ended December 31, 2014.

The SEC permits oil and gas companies to disclose probable and possible reserves in their filings with the SEC. Antero does not plan to include probable and possible reserve estimates in its filings with the SEC.  Antero has provided internally generated estimates that have been audited by its third party reserve engineer in this release.  Antero’s estimate of proved, probable and possible reserves is provided in this release because management believes it is useful information that is widely used by the investment community in the valuation, comparison and analysis of companies.  However, the Company notes that the SEC prohibits companies from aggregating proved, probable and possible reserves in filings with the SEC due to the different levels of certainty associated with each reserve category.

This release provides a summary of Antero’s reserves as of December 31, 2014, assuming ethane “rejection”.  Ethane rejection occurs when ethane is left in the wellhead natural gas stream when the natural gas is processed, rather than being separated out and sold as a liquid after fractionation.  When ethane is left in the gas stream, the Btu content of the residue natural gas at the outlet of the processing plant is higher.  Producers will generally elect to “reject” ethane at the processing plant when the price received for the ethane in the natural gas stream is greater than the price received for the ethane being sold as a liquid after fractionation, net of fractionation costs.  When ethane is recovered in the processing plant, the Btu content of the residue natural gas is lower, but a producer is then able to recover the value of the ethane sold as a separate natural gas liquid product.  In addition, natural gas processing plants can produce the other NGL products (propane, normal butane, isobutene and natural gasoline) while rejecting ethane.
