Recent Developments

Raising 2017 Guidance

The Company is raising its 2017 net production guidance from a range of 2,160 to 2,250 Bcfe/d to a range of 2,250 to 2,300 Bcfe/d. This represents a 3% increase from the previously announced guidance.  The increase in production guidance is primarily a function of the improved recoveries Antero continues to achieve through its advanced completions. Antero’s advanced completions have utilized 1,500 to 2,500 pounds of proppant per foot, averaging 2,045 pounds of proppant per foot year to date in 2017.  These techniques have yielded encouraging results with initial wellhead EURs ranging from 1.9 to 2.7 Bcf per 1,000’ of lateral as compared to the Company’s historical 1.7 Bcf per 1,000’ type curve.

While the net production guidance is being raied, there is no change to the Company’s $1.3 billion drilling and completion budget for 2017 due to continued efficiency gains.  Drilling efficiencies include a reduction in drilling days in the Marcellus from 15 days in 2016 to 12 days in the second quarter of 2017 despite drilling longer laterals.  In the second quarter of 2017, Antero drilled an average of 5,200 lateral feet per day in the Marcellus and the Company’s average completed lateral was 9,400 feet and 11,200 feet in the Marcellus and Ohio Utica, respectively.  Further, the Company continues to increase pad sizes and is currently drilling both a 12-well and a 14-well pad in the Marcellus.

1

Year to date in 2017, Antero has placed 59 total wells to sales.  Of the 54 wells Antero has completed in the Marcellus, 46, or 85%, have used greater than 1,750 pounds of proppant per foot and have generated aggregate production in excess of the Company’s 2.0 Bcf/1,000’ type curve target through 180 days.

The following table is a comparison of the original 2017 production guidance issued in January 2017 and the revised 2017 guidance.

Mid-Year 2017 Proved and 3P Reserves

Antero announced today that internally estimated proved reserves at mid-year 2017 were 16.5 Tcfe, a 7% increase compared to estimated proved reserves at December 31, 2016.  Assuming futures strip benchmark pricing and applying company-specific production weighting for Appalachian index pricing, the pre-tax present value discounted at 10% (“pre-tax PV–10”) of the June 30, 2017 estimated proved reserves was $10.1 billion, including $1.7 billion of hedge value.  All-in finding and development cost for proved reserve additions was $0.48 per Mcfe.  Drill bit only finding and development cost for proved reserve additions was $0.47 per Mcfe.  Proved developed reserves increased by 20% from year-end 2016 to 8.3 Tcfe at June 30, 2017 and the percentage of proved reserves classified as proved developed increased to 50%.  The Company’s proved, probable and possible (“3P”) reserves at mid-year 2017 totaled 53.0 Tcfe, which represents a 14% increase compared to year-end 2016.  Assuming futures strip benchmark pricing and applying the same company-specific production weighting for Appalachian index pricing, the pre-tax PV–10 of the June 30, 2017 3P reserves was $17.0 billion, including hedges.  The 3P reserve figures exclude virtually all of the Company’s Upper Devonian and West Virginia Utica resource.

Included in the mid-year 2017 reserves are 199 proved undeveloped and 398 probable locations that were upgraded to an approximate 2.0 Bcf/1,000’ type curve from a 1.7 Bcf/1,000’ type curve at year-end 2016.  There are now 294 proved undeveloped locations, or 83% of the total proved undeveloped locations in the Marcellus that are booked at an approximate 2.0 Bcf/1,000’ type curve.  The remaining 60 Marcellus proved undeveloped locations are booked at a 1.7 Bcf/1,000’ type curve.

Commenting on the continued enhanced recoveries and the impact on production and reserves, Paul Rady, Chairman and CEO, said, “We continue to see outstanding results from our advanced completions in the Marcellus that we began implementing in early 2016.  In recognition of these productivity gains, our reserve engineers have now upgraded nearly 600 proved and probable drilling locations in the Marcellus from our previous 1.7 Bcf/1,000’ type curve to an approximate 2.0 Bcf/1,000’ type curve.  The enhanced productivity from these completions combined with continued operational efficiencies has resulted in a further reduction in per unit development costs and a further increase in capital efficiency.  The enhanced completions program has also resulted in a 3% increase to our production guidance without raising capital spending guidance.”

Asset Acquisition

In early June of 2017, Antero closed on a 10,300 net acre Marcellus acquisition primarily located in Doddridge and Wetzel Counties, West Virginia for approximately $130 million.  The acquisition included approximately 17 MMcfe/d of net equivalent production, 15 drilled but uncompleted wells with an average lateral length of 8,200 feet and one undeveloped drilling pad.  Antero estimates the undeveloped properties include 418 Bcfe and 958 Bcfe of unaudited Marcellus proved reserves and 3P reserves, respectively, which were included in Antero’s mid-year reserve analysis.  In total, the acquisition adds 89 undeveloped 3P locations and enhances 74 existing 3P locations with incremental working interests and/or increased lateral length.  The lateral length of the new or enhanced 3P locations average 8,700 feet.

Second Quarter 2017 Financial and Operating Results

As of June 30, 2017, Antero owned a 58% limited partner interest in Antero Midstream Partners LP (“Antero Midstream”).  Antero Midstream’s results are consolidated with Antero’s results.

For the three months ended June 30, 2017, the Company reported a net loss of $5 million, or $(0.02) per basic and diluted share, compared to a net loss of $596 million, or $(2.12) per basic and diluted share, in the second quarter of 2016.  The net loss for the second quarter of 2017 included the following items:

·Non-cash gain on unsettled hedges of $55 million

·Non-cash equity-based compensation expense of $27 million

·Impairment of unproved properties of $15 million

·Income tax effect of these reconciling items of $5 million

Excluding the items detailed above, the Company’s results for the second quarter of 2017 were as follows:

·Adjusted net loss of $13 million, or $(0.04) per basic and diluted share, a 132% decrease compared to adjusted net income of $41 million in the second quarter of 2016

·Adjusted EBITDAX of $321 million, a 3% decrease compared to the second quarter of 2016

For a description of adjusted net loss and adjusted EBITDAX and reconciliations to their nearest comparable GAAP measures, please read “Non-GAAP Financial Measures.”

Antero’s net daily production for the second quarter of 2017 averaged 2,200 MMcfe/d, including 102,766 Bbl/d of liquids (28% liquids).  Second quarter 2017 production represents an organic production growth rate of 25% from the second quarter of 2016 and a 3% increase compared to the first quarter of 2017.  Second quarter 2017 C3+ natural gas liquids (“NGLs”) and oil production averaged 68,026 Bbl/d and 6,738 Bbl/d, respectively.  Ethane (C2) production averaged 28,003 Bbl/d while leaving approximately 91,710 Bbl/d of ethane in the natural gas stream.  Total liquids production of 102,766 Bbl/d for the second quarter of 2017 represents an organic production growth rate of 37% and 4% as compared to the second quarter of 2016 and first quarter of 2017, respectively.

Commenting on capital spending and cash flow levels, Glen Warren, President and CFO, said, “Our ability to grow production 25% year-over-year while essentially holding capital spending flat speaks to our material gains in capital efficiency, especially in the face of the commodity down cycle.  These gains are driven by a combination of drilling efficiencies which we have continued to achieve and the operational momentum we have been able to sustain through the downturn due to our ability to lock in volumes and pricing through our hedge book and firm transportation portfolio.  Looking ahead, we expect to continue to build off this momentum as we are targeting 20% to 22% production growth in 2018 while maintaining a D&C budget at or below 2017 levels. Furthermore, we are targeting drilling and completion capital to be within discretionary cash flow in 2018.”

Antero’s average natural gas price before hedging increased 63% from the prior year quarter to $3.15 per Mcf, a $0.03 differential to the average Nymex natural gas price for the period.  Antero’s average realized natural gas price after hedging for the second quarter of 2017 was $3.53 per Mcf, a $0.35 premium to the Nymex average natural gas price for the period, and an 18% decrease compared to the prior year quarter.  During the quarter, Antero realized a cash settled natural gas hedge gain of $55 million, or $0.38 per Mcf compared to $283 million, or $2.38 per Mcf in the prior year quarter.

The Company’s average realized C3+ NGL price before hedging for the second quarter of 2017 was $24.14 per barrel, or 50% of the average Nymex WTI oil price, which represents a 41% increase as compared to the prior year quarter.  The improvement in C3+ NGL pricing is primarily due to an increase in Mont Belvieu pricing combined with an improvement in local differentials.  Antero’s average realized C3+ NGL price including hedges was $19.92 per barrel, a 5% increase compared to the second quarter of 2016.  The Company’s average realized ethane price before hedging for the second quarter of 2017 was $0.20 per gallon, or $8.40 per barrel.   Antero’s average realized ethane price including hedges for the second quarter of 2017 was $0.21 per gallon, or $8.61 per barrel.  The average realized oil price before hedging was $43.24 per barrel, a $5.00 differential to Nymex WTI for the period and a 23% increase as compared to the second quarter of 2016.  Antero’s average realized oil price including hedges was $46.12 per barrel, a $2.12 differential to Nymex WTI for the period.

Antero’s average natural gas-equivalent price including C2+ NGLs and oil, but excluding hedge settlements, increased from the prior year quarter by $1.13 to $3.26 per Mcfe.  The Company’s average natural gas-equivalent price, including C2+ NGLs, oil and hedge settlements, decreased by 14% to $3.41 per Mcfe compared to the prior year quarter.  For the second quarter of 2017, Antero realized a total cash settled hedge gain on all products of $31 million, or $0.16 per Mcfe.

Total operating revenue for the second quarter of 2017 was $790 million as compared to a $249 million loss for the second quarter of 2016.  Operating revenue for the second quarter of 2017 included a $55 million non-cash gain on unsettled hedges, while the second quarter of 2016 included a $977 million non-cash loss on unsettled hedges.  Revenue excluding the unrealized hedge gain for the quarter was $736 million, which was in line with the second quarter of 2016.  Liquids production contributed 30% of total product revenues before hedges in the second quarter of 2017.  For a reconciliation of revenue excluding unrealized hedge (gains) losses to operating revenue, the most comparable GAAP measure, please read “Non-GAAP Financial Measures.”

Marketing revenue for the second quarter of 2017 was $50 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 Tennessee, Columbia Gas and Rockies Express Pipelines.  Marketing expense for the second quarter of 2017 was $77 million, including costs related to excess capacity and the cost of purchasing third party gas.  Net marketing expense was $27 million, or $0.14 per Mcfe, for the second quarter of 2017, representing a 36% or $0.08 per Mcfe decrease from the second quarter of 2016.  The reduction in net marketing expense was primarily driven by the decrease in unutilized excess firm transportation capacity, a portion of which was assumed by a third party beginning July 1, 2016.

Per unit cash production expense (lease operating, gathering, compression, processing, transportation, and production and ad valorem taxes) for the second quarter of 2017 was $1.52 per Mcfe, a 3% increase compared to $1.48 per Mcfe in the prior year quarter.  The increase is primarily a result of an increase in fuel costs as compared to the prior year due to higher natural gas prices.  The per unit cash production expense for the quarter included $0.08 per Mcfe for lease operating costs, $1.33 per Mcfe for gathering, compression, processing and transportation costs and $0.11 per Mcfe for production and ad valorem taxes.  Per unit general and administrative expense for the second quarter of 2017, excluding non-cash equity-based compensation expense, was $0.19 per Mcfe, a 10% decrease from the second quarter of 2016, driven by a 25% increase in production.  Per unit depreciation, depletion and amortization expense decreased 18% from the prior year quarter to $1.01 per Mcfe, primarily driven by increases in Antero’s estimated recoverable reserves combined with decreases in its per unit development costs.  For the Marcellus, per unit depreciation, depletion and amortization expense decreased 19% from the prior year quarter to $0.85 per Mcfe.

Adjusted EBITDAX of $321 million for the second quarter of 2017 represents a 3% decrease compared to the prior year quarter.  Adjusted EBITDAX margin for the quarter was $1.60 per Mcfe, representing a 23% decrease from the prior year quarter, driven primarily by a reduction in gains on settled derivatives.  For the second quarter of 2017, cash flow from operations was $254 million, a 6% increase from the prior year quarter.  Cash flow from operations before changes in working capital was $251 million, a 7% decrease from the second quarter of 2016.

Marcellus Shale — Antero completed and placed on line 29 horizontal Marcellus wells during the second quarter of 2017 with an average lateral length of 9,380 feet.  During the period, Antero drilled an average of 5,200 lateral feet per day, which represents a 50% increase compared to 2016.

Current average well costs are $0.9 million per 1,000 feet of lateral in the Marcellus assuming a 2,000 pounds of proppant per foot completion.  Average drilling days from spud to final rig release was 12 days in the second quarter of 2017, a 4% reduction from 2016.  Antero is currently operating four drilling rigs and three completion crews in the Marcellus Shale.

In late March 2017, Antero placed two wells to sales on a pad with average lateral lengths of 13,700 feet.  The 13,700’ laterals each averaged 26 MMcfe/d of production in the first 30 days and have an average wellhead EUR of 2.1 Bcf/1000’ and a processed EUR of 2.5 Bcfe/1,000’.  The two wells have an average EUR of approximately 34 Bcfe per well.

In mid-July of 2017, the Sherwood 8 processing plant (200 MMcf/d) was placed into service.  The Sherwood 8 plant is the second Antero Midstream / MPLX joint venture (the “Joint Venture”) plant placed in service during the year and is already 100% utilized.  The Joint Venture’s next plant, Sherwood 9 (200 MMcf/d), is expected to be in service in January of 2018.

Ohio Utica Shale — Antero completed and placed on line 5 horizontal Utica wells during the second quarter of 2017 with an average lateral length of 11,222 feet.  During the period, Antero set a record for drilling its longest lateral to date at 17,380 feet.  This lateral was drilled within a 7 foot target zone and was drilled in 12 days.  The well is expected to be placed to sales in the third quarter of 2017.

Current average well costs are $1.0 million per 1,000 feet of lateral in the Utica.  Antero is currently operating two drilling rigs and two completion crews in the Utica Shale.

Non-GAAP Financial Measures

Revenue excluding unrealized hedge (gains) losses as set forth in this release represents total operating revenue adjusted for non-cash (gains) losses on unsettled hedges.  Antero believes that revenue excluding unrealized hedge (gains) losses is useful to investors in evaluating operational trends of the Company and its performance relative to other oil and gas producing companies.  Revenue excluding unrealized hedge (gains) losses 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 revenue excluding unrealized hedge (gains) losses (in thousands):

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 items.  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.

Adjusted EBITDAX is a non-GAAP financial measure that the Company defines as net income from continuing operations including noncontrolling interest 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, 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.  Adjusted EBITDAX is also used by our Board of Directors as a performance measure in determining executive compensation.  Adjusted EBITDAX, as defined by our credit facility, is used by our lenders pursuant to covenants under our revolving 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, 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 tables represent a reconciliation of the Company’s net income (loss) from continuing operations including noncontrolling interest to adjusted EBITDAX, a reconciliation of adjusted EBITDAX to net cash provided by operating activities and a reconciliation of realized price before cash receipts for settled hedges to adjusted EBITDAX margin (in thousands except adjusted EBITDAX margin).

Antero Resources is an independent natural gas and oil company engaged in the acquisition, development and production of unconventional liquids-rich natural gas properties located in the Appalachian Basin in West Virginia and Ohio. The Company’s website is located at www.anteroresources.com.

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, except for statements of historical fact, made in this release regarding activities, events or developments the Company expects, believes or anticipates will or may occur in the future, such as those regarding future production targets, completion of natural gas or natural gas liquids transportation projects, future earnings, future capital spending plans, improved and/or increasing capital efficiency, continued utilization of existing infrastructure, gas marketability, estimated realized natural gas and natural gas liquids prices, acreage quality, access to multiple gas markets, expected drilling and development plans, future financial position, future technical improvements and future marketing opportunities, are 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 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, 2016.

Reserves Disclosure

In this release, Antero has provided a number of unaudited reserve metrics, which include all-in finding and development cost per unit and drill bit only finding and development cost per unit.  These non-GAAP metrics are commonly used in the exploration and production industry by companies, investors and analysts in order to measure a company’s ability of adding and developing reserves at a reasonable cost.  The finding and development costs per unit are statistical indicators that have limitations, including their predictive and comparative value. In addition, because the finding and development costs per unit do not consider the cost or timing of future production of new reserves, such measures may not be adequate measures of value creation. These reserve metrics may not be comparable to similarly titled measurements used by other companies. The calculations for both all-in and drill bit only finding and development cost per unit do not include future development costs required for the development of proved undeveloped reserves.

Pre-tax PV—10 values and pre-tax PV-10 values including hedges are non-GAAP financial measures as defined by the SEC.  Antero believes that the presentation of these pre-tax PV—10 values are relevant and useful to its investors because it presents the discounted future net cash flows attributable to reserves and hedges prior to taking into account corporate future income taxes and the Company’s current tax structure.  The Company further believes investors and creditors use pre-tax PV—10 values

10

as a basis for comparison of the relative size and value of its reserves and hedges as compared with other companies.  Antero believes that PV—10 estimates using strip pricing and including hedges can be used within the industry and by creditors and securities analysts to evaluate estimated net cash flows in the current commodity price environment.  PV—10 estimates using strip pricing are not adjusted for the likelihood that the pricing scenario will occur, and thus they may not be comparable to PV—10 value using SEC pricing.

The GAAP financial measure most directly comparable to pre-tax PV—10 is the standardized measure of discounted future net cash flows (“Standardized Measure”).  With respect to PV-10 calculated as of an interim date, it is not practical to calculate the taxes for the related interim period because GAAP does not provide for disclosure of standardized measure on an interim basis.
