·                  Realized combined natural gas equivalent price of $3.56 per Mcfe before hedges, driven by a $0.42 per Mcfe uplift from liquids production

·                  Realized natural gas equivalent price of $4.04 per Mcfe after hedges

·                  Net income of $15 million, or $0.05 per diluted share, non-GAAP adjusted net income of $141 million, or $0.44 per diluted share, and non-GAAP Stand-Alone adjusted net income of $136 million

·                  Adjusted EBITDAX of $551 million and Stand-Alone adjusted EBITDAX of $488 million, a 51% and 52% increase over the prior year period, respectively

·                  100% hedged on targeted 2018 and 2019 natural gas production at $3.50 per MMBtu

Commenting on the quarter, Paul Rady, Chairman and CEO said, “We are off to a strong start in 2018 with record first quarter results that delivered strong cash flow growth during the quarter. This included a net marketing gain, and reduced leverage from year-end levels.  We continued to achieve strong operational execution with fewer drilling days per well and higher completion stages per day during the quarter than forecast. Furthermore, the ongoing liquids focus in the Marcellus and strong production performance in the Utica Shale during the quarter boosted results.  We continue to execute on the plan we laid out at the beginning of the year targeting strong cash flow generation and debt reduction over the next several years.”

Financial and operational results are reported and discussed on a consolidated basis, unless otherwise noted.  Please read “Non-GAAP Financial Measures” for:

First Quarter 2018 Financial Results

As of March 31, 2018, Antero owned a 53% limited partner interest in Antero Midstream Partners LP (“Antero Midstream”).  Antero Midstream’s results are consolidated within Antero’s results.

Antero reported first quarter net income of $15 million, or $0.05 per diluted share, compared to net income of $268 million, or $0.85 per diluted share, in the prior year period.  Excluding items detailed in “Non-GAAP Financial Measures,” first quarter adjusted net income was $141 million, or $0.44 per diluted share, compared to $56 million, or $0.18 per diluted share, in the prior year period.  First quarter Stand-Alone adjusted net income was $136 million compared to $52 million in the prior year period.  Adjusted EBITDAX was $551 million, compared to $365 million in the prior year period, and Stand-Alone adjusted EBITDAX was $488 million, compared to $321 million in the prior year period. First quarter 2018 results include settled marketing derivatives of $110 million, resulting in an overall gain of $94 million, net of unrealized losses.

The following table details the components of average net production and average realized prices for the three months ended March 31, 2018:

Net daily natural gas equivalent production in the first quarter averaged 2,376 MMcfe/d, including 102,798 Bbl/d of liquids (26% liquids), representing an organic growth rate of 11% versus the prior year period and a 1% increase sequentially.  Natural gas production averaged 1,759 MMcf/d (average BTU of 1094), C3+ NGLs production averaged 63,252 Bbl/d, oil production averaged 5,887 Bbl/d, and recovered ethane production averaged 33,659 Bbl/d.  Total liquids production grew 4% versus the prior year period and declined 4% sequentially.  The sequential decline in liquids production from the fourth quarter of 2017 was a result of the impact of winter weather and downtime associated with processing plants.  Liquids revenue represented approximately 35% of total product revenue before hedges, an increase from 32% of total product revenue in the prior year period.

Antero’s average realized natural gas price before hedging was $3.14 per Mcf, a $0.14 per Mcf premium to the average NYMEX price during the period.   Including hedges, Antero’s average realized natural gas price was $3.85 per Mcf, an $0.85 premium to the NYMEX average price, reflecting the realization of a cash settled natural gas hedge gain of $111 million or $0.71 per Mcf.  Based on current strip prices, Antero’s full year realized natural gas prices are trending toward the high end of its guidance range of a $0.00 to $0.05 per Mcf premium to NYMEX before hedges.

Antero’s average realized C3+ NGL price before hedging was $36.38 per barrel, or 58% of the average NYMEX WTI oil price, representing a 23% increase versus the prior year period.  Including hedges, Antero’s average realized C3+ NGL price was $35.17 per barrel, a 46% increase versus the prior year period, reflecting the realization of a cash settled C3+ hedge loss of $7 million or $1.21 per barrel.  Based on current strip prices, Antero is trending toward the low end of its 62.5% to 67.5% guidance range for C3+ NGL

2

realized prices as a percentage of WTI, as oil prices have risen but C3+ NGL strip prices have remained consistent relative to year-end 2017 levels.

Antero’s average realized oil price before hedging was $57.14 per barrel, a $5.74 negative differential to average NYMEX WTI and a 36% increase versus the prior year period.  Including hedges, the average realized oil price was $51.12 per barrel, an $11.76 differential to average NYMEX WTI.  The average realized ethane price was $0.21 per gallon, or $8.94 per barrel.

Antero’s average natural gas equivalent price including recovered C2+ NGLs and oil, but excluding hedge settlements, was $3.56 per Mcfe, in line with the prior year period.  Including hedges, the Company’s average natural gas equivalent price was $4.04 per Mcfe, a 6% increase from the prior year period, primarily driven by higher realized natural gas hedge gains and lower C3+ hedge losses compared to the prior year period.  Net cash settled hedge gains on all products were $101 million, or $0.48 per Mcfe.

Operating revenues in the first quarter were $1.028 billion compared to $1.196 billion in the prior year period.  Revenue included a $79 million non-cash loss on unsettled hedges and a $16 million non-cash loss on unsettled marketing derivatives, while the prior year included a $394 million non-cash gain on unsettled hedges.  Revenue excluding unrealized derivative losses was $1.123 billion, a 40% increase versus the prior year period.  Liquids production contributed 35% of total product revenues before hedges, compared to a 32% contribution in the prior year period.  Please see “Non-GAAP Financial Measures” for a description of revenue excluding the unrealized hedge gain and unrealized marketing derivative loss.

The following table presents a reconciliation of realized price before cash receipts for settled hedges to Stand-Alone and consolidated adjusted EBITDAX margin for the three months ended March 31, 2017 and 2018:

(1)         Includes cash receipts for settled marketing derivative gains.

Stand-Alone per unit cash production expense (lease operating, gathering, compression, processing, transportation, and production and ad valorem taxes) was $2.07 per Mcfe, a 4% increase compared to $2.00 per Mcfe in the prior year period.  The per unit cash production expense for the quarter included $0.15 per Mcfe for lease operating costs, $1.80 per Mcfe for gathering, compression, processing and transportation costs and $0.12 per Mcfe for production and ad valorem taxes.  The increase in lease operating expenses to $0.15 per Mcfe in the first quarter is due to an increase in produced water on new well pads, which is attributable to an increase in the amount of water used in our advanced well completions throughout the year.

Stand-Alone per unit net marketing gains were $0.27 per Mcfe compared to a net marketing expense of $0.12 per Mcfe reported in the prior year period.  As a result of severe cold weather in January that drove wide basis premiums at the index for certain contracts, the Company was able to sell previously purchased gas at a large premium resulting in a realized gain on settled marketing derivatives of $110 million during the three months ended March 31, 2018.  For the period of April through October, 2018, Antero expects to realize a loss on settled marketing derivatives of $37 million related to these contracts.  See note 11 to the condensed consolidated financial statements in Antero’s Form 10-Q for more information on these contracts.

3

Stand-Alone per unit general and administrative expense, excluding non-cash equity-based compensation expense, was $0.15 per Mcfe, a 6% decrease from the prior year period.

Stand-Alone Adjusted EBITDAX was $488 million for the first quarter of 2018, compared to $321 million in the prior year period.  Stand-Alone adjusted EBITDAX margin was $1.80 per Mcfe before settled hedges, a 26% increase from the prior year period.  Stand-Alone adjusted EBITDAX margin including hedges was $2.28 per Mcfe, a 37% increase from the prior year period.  Adjusted EBITDAX was $551 million, compared to $365 million in the prior year period.  Adjusted EBITDAX margin was $2.10 per Mcfe before settled hedges and $2.58 per Mcfe including settled hedges, compared to $1.66 per Mcfe and $1.89 per Mcfe, respectively, in the prior year period.

Stand-Alone net cash provided by operating activities was $498 million for the period.  Stand-Alone Adjusted Operating Cash Flow was $433 million, a 66% increase over the prior year period.  Net cash provided by operating activities was $542 million for the period.  Adjusted Operating Cash Flow was $485 million during the first quarter, a 64% increase compared to the prior year period.  Stand-Alone Adjusted Operating Cash Flow and Adjusted Operating Cash Flow increased versus the prior year period primarily due to higher production, liquids pricing after hedges, and net marketing gains realized during the quarter.

President and CFO Glen Warren commented, “Due to our comprehensive focus on capital efficiency and deleveraging including our hedge and asset monetization program last fall, our Stand-Alone financial leverage declined to 2.5x at quarter end.  We are focused on executing our 2018 operational and financial plan, and are on track to deliver attractive debt-adjusted production per share growth, while living within cash flow and further reducing leverage.”

Operating Update

First Quarter 2018

Marcellus Shale — Antero completed and placed on line 16 horizontal Marcellus wells during the first quarter of 2018 with an average lateral length of 9,100’ and a 30-day rate of 19.8 MMcfe/d (with 25% ethane recovery) on choke.  Current average well costs are $0.85 million per 1,000’ of lateral in the Marcellus assuming the 2018 average lateral length of 10,000’ and 2,000 pounds of proppant per foot completion.  Antero plans to operate five drilling rigs and four completion crews in the Marcellus Shale play during 2018.

Notable drilling and completion efficiency gains were achieved during the quarter, despite severe winter weather disruptions at times.  During the period, Antero drilled an average of over 4,700 feet per day when drilling in the lateral section of the well, which represents a 4% increase compared to full year 2017.  In addition, in one well Antero drilled 8,206 lateral feet in a 24 hour period, the Company record lateral footage for a 24-hour period.  Average drilling days from spud to final rig release were 11.5 days in the first quarter of 2018, a 6% reduction from the full year 2017.  The Company completed 4.3 stages per day on average during the first quarter, improving to 5.1 in the month of March as weather factors abated, levels which exceeded the 4.1 stages per day average from the fourth quarter of 2017 and the 4.5 stages per day budgeted for 2018.  Antero also completed its longest Marcellus lateral to date at nearly 14,400’ during the period.

The Company is preparing to commence production on its two largest Marcellus pads to date. One 12-well pad has a planned combined total of 120,000 lateral feet and the other 12-well pad has 106,000 lateral feet.  Antero expects to place these 24 wells to sales within the month, with expected production at a combined 90-day gross rate of 350 to 400 MMcfe per day, on choke, including over 20,000 barrels per day of liquids.

Ohio Utica Shale — Antero placed five horizontal Ohio Utica wells to sales during the first quarter of 2018 with an average lateral length of approximately 11,000 feet.  During the period, Antero drilled four wells with an average lateral length of 9,200 feet in 15.5 total days from spud to final rig release, which represents a 7% decrease in drilling days compared to 2016 where wells were drilled at a similar lateral length.

Current average well costs are $0.91 million per 1,000 feet of lateral in the Ohio Utica assuming the 2018 average lateral length of 12,000’ and a 2,000 pound proppant per foot completion.  Antero plans to operate one drilling rig and one completion crew in the Ohio Utica Shale during 2018.

During the quarter, Antero commenced completion operations on five wells in Ohio, including four wells each at 17,400’ in lateral length.  These wells represent Antero’s longest wells drilled and completed to date, and are expected to be placed to sales next month.

4

In addition, average stages per day were 5.1 during the quarter, significantly above the 3.7 stages per day achieved during the fourth quarter of 2017.

Antero turned 10 wells to sales in December 2017 with an average lateral length of 10,200’ each that represented its first wells completed in the Ohio Utica dry gas regime.  These wells have produced over 24 Bcf of dry gas to date (20 MMcf/d average per well) and have not yet begun to decline after approximately 130 days on line.

Non-GAAP Financial Measures

Revenue Excluding Unrealized Derivative Losses

Revenue excluding unrealized hedge gains as set forth in this release represents total operating revenue adjusted for non-cash gains on unsettled hedges and marketing derivatives.  Antero believes that revenue excluding unrealized hedge gains and marketing derivative gains 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 and marketing derivative gains 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 and marketing derivative gains:

Adjusted Net Income & Stand-Alone Adjusted Net Income

Adjusted net income as set forth in this release represents net income, adjusted for certain items.  Stand-Alone adjusted net income as presented in this release represents net income that will be reported in the Parent column of Antero’s guarantor footnote to its financial statements, adjusted for certain items.  Antero believes that adjusted net income 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 and Stand-Alone adjusted net income are not measures of financial performance under GAAP and should not be considered in isolation or as a substitute for net income as an indicator of financial performance.

The following table reconciles net income (loss) to adjusted net income (in thousands) and Stand-Alone net income (loss) to Stand-Alone adjusted net income (in thousands):

Adjusted Operating Cash Flow and Stand-Alone Adjusted Operating Cash Flow

Adjusted Operating Cash Flow as presented in this release represents net cash provided by operating activities before changes in working capital items.  Stand-Alone Adjusted Operating Cash Flow as presented in this release represents net cash provided by operating activities that will be reported in the Parent column of Antero’s guarantor footnote to its financial statements before changes in working capital items.  Adjusted Operating Cash Flow 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.  Adjusted Operating Cash Flow 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.

Management believes that Adjusted Operating Cash Flow and Stand-Alone Adjusted Operating Cash Flow are useful indicators of the company’s ability to internally fund its activities and to service or incur additional debt on a consolidated and Stand-Alone basis. Management believes that changes in current assets and liabilities, which are excluded from the calculation of these measures, relate to the timing of cash receipts and disbursements and therefore may not relate to the period in which the operating activities occurred and generally do not have a material impact on the ability of the company to fund its operations.

There are significant limitations to using Adjusted Operating Cash Flow and Stand-Alone Adjusted Operating Cash Flow as measures of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect the company’s net income on a consolidated and Stand-Alone basis, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted Operating Cash Flow and Stand-Alone Adjusted Operating Cash Flow reported by different companies.  Adjusted Operating Cash Flow and Stand-Alone Adjusted Operating Cash Flow do not represent funds available for discretionary use because those funds may be required for debt service, land acquisitions and lease renewals, other capital expenditures, working capital, income taxes, exploration expenses, and other commitments and obligations.

Adjusted Operating Cash Flow 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 Adjusted Operating Cash Flow as used in this release (in thousands):

Total Debt and Net Debt

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

Adjusted EBITDAX and Stand-Alone Adjusted EBITDAX

Adjusted EBITDAX as defined by the Company represents net income or loss, including noncontrolling interests, before interest expense, interest income, derivative fair value gains or losses, but including net cash receipts or payments on derivative instruments included in derivative fair value gains or losses, taxes, impairments, depletion, depreciation, amortization, and accretion, exploration expense, equity-based compensation, gain or loss on early extinguishment of debt, and gain or loss on sale of assets. Adjusted EBITDAX also includes distributions from unconsolidated affiliates and excludes equity in earnings or losses of unconsolidated affiliates.

Stand-Alone adjusted EBITDAX as defined by the Company represents income or loss as reported in the Parent column of Antero’s guarantor footnote to its financial statements before interest expense, interest income, gains or losses from commodity derivatives and marketing derivatives, but including net cash receipts or payments on derivative instruments included in derivative gains or losses, income taxes, impairments, depletion, depreciation, amortization, and accretion, exploration expense, equity-based compensation, gain or loss on early extinguishment of debt, gain or loss on sale of assets, equity in earnings or loss of Antero Midstream and gain or loss on changes in the fair value of contingent acquisition consideration. Stand-Alone adjusted EBITDAX also includes distributions received from limited partner interests in Antero Midstream common units.

9

The GAAP financial measure nearest to Adjusted EBITDAX is net income or loss including noncontrolling interest that will be reported in Antero’s condensed consolidated financial statements.  The GAAP financial measure nearest to Stand-Alone Adjusted EBITDAX is Stand-Alone net income or loss that will be reported in the Parent column of Antero’s guarantor footnote to its financial statements. While there are limitations associated with the use of Adjusted EBITDAX and Stand-Alone Adjusted EBITDAX described below, management believes that these measures are useful to an investor in evaluating the company’s financial performance because these measures:

·                  are 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 (both on a consolidated and Stand-Alone basis) from period to period by removing the effect of its capital structure from its operating structure; and

·                  is used by management for various purposes, including as a measure of Antero’s operating performance (both on a consolidated and Stand-Alone basis), in presentations to the company’s board of directors, and as a basis for strategic planning and forecasting. Adjusted EBITDAX is also used by the 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 and Stand-Alone Adjusted EBITDAX as measures of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect the company’s net income on a consolidated and Stand-Alone basis, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted EBITDAX reported by different companies.  In addition, Adjusted EBITDAX and Stand-Alone Adjusted EBITDAX provide no information regarding a company’s capital structure, borrowings, interest costs, capital expenditures, and working capital movement or tax position.

Antero Midstream Adjusted EBITDA & Distributable Cash Flow

Antero Midstream views Adjusted EBITDA as an important indicator of its performance.  Antero Midstream defines Adjusted EBITDA as Net Income before interest expense, depreciation expense, impairment expense, accretion of contingent acquisition consideration, equity-based compensation expense, excluding equity in earnings of unconsolidated affiliates and including cash distributions from unconsolidated affiliates.

Antero Midstream uses Adjusted EBITDA to assess:

·                  the financial performance of Antero Midstream’s assets, without regard to financing methods in the case of Adjusted EBITDA, capital structure or historical cost basis;

·                  its operating performance and return on capital as compared to other publicly traded partnerships in the midstream energy sector, without regard to financing or capital structure; and

·                  the viability of acquisitions and other capital expenditure projects.

Antero Midstream defines Distributable Cash Flow as Adjusted EBITDA less interest paid, income tax withholding payments and cash reserved for payments of income tax withholding upon vesting of equity-based compensation awards, cash reserved for bond interest and ongoing maintenance capital expenditures paid.  Antero Midstream uses Distributable Cash Flow as a performance metric to compare the cash generating performance of Antero Midstream from period to period and to compare the cash generating performance for specific periods to the cash distributions (if any) that are expected to be paid to unitholders.  Distributable Cash Flow does not reflect changes in working capital balances.

Adjusted EBITDA and Distributable Cash Flow are non-GAAP financial measures.  The GAAP measure most directly comparable to Adjusted EBITDA and Distributable Cash Flow is Net Income.  The non-GAAP financial measures of Adjusted EBITDA and Distributable Cash Flow should not be considered as alternatives to the GAAP measure of Net Income.  Adjusted EBITDA and Distributable Cash Flow are not presentations made in accordance with GAAP and have important limitations as an analytical tool because they include some, but not all, items that affect Net Income and Adjusted EBITDA.  You should not consider Adjusted EBITDA and Distributable Cash Flow in isolation or as a substitute for analyses of results as reported under GAAP.  Antero Midstream’s definition of Adjusted EBITDA and Distributable Cash Flow may not be comparable to similarly titled measures of other partnerships.

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 Antero’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, 2017.

In this press release, Antero uses terms such as “resource potential” to describe potentially recoverable hydrocarbon quantities that are not permitted to be used in filings with the SEC.  Antero includes these estimates to demonstrate what management believes to be the potential for future drilling and production on our

properties.  These estimates are by their nature much more speculative than estimates of proved reserves and would require substantial additional capital spending over significant number of years to implement recovery.  Actual quantities that may be ultimately recovered from Antero’s interests may differ substantially from the estimates in this press release.  Factors affecting ultimate recovery include the scope of Antero’s ongoing drilling program, which will be directly affected by commodity prices, the availability of capital, drilling and production costs, availability of drilling services and equipment, drilling results, lease expirations, transportation constraints, regulatory approvals and other factors, and actual drilling results, including geological and mechanical factors affecting recovery rates.
