Antero’s net daily production for the second quarter of 2016 averaged 1,762 MMcfe/d, including 75,041 Bbl/d of liquids (26% liquids).  Second quarter 2016 production represents an organic production growth rate of 19% from the second quarter of 2015 and flat compared to the first quarter of 2016.  During the second quarter, Antero shut in 7.3 Bcfe, representing 80 MMcfe/d of production for the quarter due to operational downtime in late June at the Sherwood Processing Plant in West Virginia.  Antero currently has no production shut in.  Second quarter 2016 C3+ natural gas liquids (“NGLs”) and oil production averaged 52,424 Bbl/d and 5,244 Bbl/d, respectively, while ethane (C2) production averaged 17,373 Bbl/d. Total liquids production for the second quarter of 2016 represents an organic production growth rate of 63% and 10% from the second quarter of 2015 and first quarter of 2016, respectively.

Antero’s average natural gas price before hedging decreased 12% from the prior year quarter to $1.93 per Mcf, a $0.02 per Mcf negative differential to Nymex, as Nymex natural gas prices decreased 26% from the prior year quarter.  Approximately 99% of Antero’s second quarter 2016 natural gas revenue was realized at currently favorable price indices, including Columbia Gas Transmission (TCO), Chicago, MichCon, Tennessee Gulf and Nymex.  Antero’s average realized natural gas price after hedging for the second quarter of 2016 was $4.31 per Mcf, a $2.36 premium to the Nymex average price for the period.  This represents a 12% increase compared to the prior year quarter.  During the quarter, Antero realized a cash settled natural gas hedge gain of $283 million, or $2.38 per Mcf.

The Company’s average realized C3+ NGL price before hedging for the second quarter of 2016 was $17.08 per barrel, or 38% of the Nymex WTI oil price, which represents a 5% increase as compared to the prior year quarter.  Average realized oil price was $35.08 per barrel, a 20% decrease as compared to the second quarter of 2015 due to a 21% decrease in the Nymex WTI oil price.  Antero’s average realized ethane price for the second quarter of 2016 was $8.36 per barrel, or $0.20 per gallon.  Antero’s average realized C3+ NGL price including hedges was $18.98 per barrel, or $0.45 per gallon, a 3% decrease as compared to the second quarter of 2015.

Antero’s average natural gas-equivalent price including C2+ NGLs and oil, but excluding hedge settlements, decreased from the prior year quarter by 11% to $2.13 per Mcfe due to a 21% decline in Nymex WTI and a 26% decline in Nymex natural gas prices.  The Company’s average natural gas-equivalent price, including C2+ NGLs, oil and hedge settlements, increased by 3% to $3.95 per Mcfe for the second quarter of 2016 as compared to the second quarter of 2015.  For the second quarter of 2016, Antero realized a hedge settlement gain of $293 million, or $1.82 per Mcfe.

Total operating revenue for the second quarter of 2016 was $(249) million as compared to $377 million for the second quarter of 2015.  Operating revenue for the second quarter of 2016 included a $977 million non-cash loss on unsettled hedges, while the second quarter of 2015 included a $198 million non-cash loss on unsettled hedges.  In both periods, the non-cash loss on unsettled hedges was driven by increasing natural gas prices during the period.  Revenue excluding the unrealized hedge loss was $728 million, a 27% increase compared to the second quarter of 2015.  Liquids production contributed 33% of total revenue before hedges in the second quarter of 2016, as compared to a 25% contribution for the prior year quarter.  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 2016 was $91 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 Gas Pipeline.  Marketing expense for the second quarter of 2016 was $126 million.  The largest components of marketing expense were the costs related to excess capacity and the cost of purchasing third party gas.  Combining the two, net marketing expense was $35 million or $0.22 per Mcfe for the second quarter of 2016.  For the second half of 2016, due to a third party contractual commitment effective July, 1, 2016, Antero has released to a third party certain unutilized firm transportation capacity and the costs associated with the unutilized capacity.  As a result of the reduction in marketing expense, Antero expects net marketing expense to decrease to a range of $0.10 to $0.15 per Mcfe for the second half of 2016.

Per unit cash production expense (lease operating, gathering, compression, processing, transportation, and production tax) for the second quarter of 2016 was $1.48 per Mcfe, a 2% increase compared to $1.45 per Mcfe in the prior year quarter.  The per unit cash production expense for the quarter included $0.08 per Mcfe for lease operating costs, $1.29 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 2016, excluding non-cash equity-based compensation expense, was $0.21 per Mcfe, a 9% decrease from the second quarter of 2015.  The significant per unit decrease in general and administrative expenses was primarily driven by the increase in production.  Per unit depreciation, depletion and amortization expense decreased 6% from the prior year quarter to $1.23 per Mcfe, primarily driven by lower development costs.

Adjusted EBITDAX of $332 million for the second quarter of 2016 represents a 24% increase compared to the prior year quarter.  Adjusted EBITDAX margin for the quarter was $2.06 per Mcfe, representing a 4% increase from the prior year quarter.  For the second quarter of 2016, cash flow from operations before changes in working capital was $269 million, a 29% increase from the prior year quarter.

Antero Midstream Financial Results

Antero Midstream results were released today and are available at www.anteromidstream.com.

Low pressure gathering volumes for the second quarter of 2016 averaged 1,353 MMcf/d, a 40% increase from the second quarter of 2015 and a 4% increase sequentially.  High pressure gathering volumes for the second quarter of 2016 averaged 1,253 MMcf/d, a 5% increase from the second quarter of 2015 and a 3% increase sequentially.  Compression volumes for the second quarter of 2016 averaged 658 MMcf/d, a 45% increase from the second quarter of 2015 and a 9% increase sequentially.  The increase in gathering and compression volumes was due to production growth from Antero in Antero Midstream’s area of dedication.  Condensate gathering volumes averaged 1,983 Bbl/d during the quarter, a 34% decrease compared to the prior year quarter and a 33% decrease sequentially. The sequential decrease in condensate gathering volumes was driven by Antero shifting Ohio Utica Shale development from its Highly-Rich Gas/Condensate area to higher rate of return drilling in the Highly-Rich Gas area, as well as the shifting of Antero Resources’ development program to the Marcellus Shale from the Utica Shale, due to firm transportation constraints to premium markets in the Utica Shale.  Fresh water delivery volumes averaged 105,379 Bbl/d during the quarter, an 11% increase compared to the prior year quarter and an 8% increase sequentially.  The increase in fresh water delivery volumes was driven by operational efficiencies leading to accelerated Marcellus completions and an increase in the average water used per foot in completions to 41 barrels, a 25% increase as compared to 2015 and an 11% increase compared to the first quarter of 2016.

For the three months ended June 30, 2016, the Partnership reported revenues of $137 million. Revenues increased 55% compared to the prior year quarter, primarily driven by the startup of produced water handling and high rate transfer services in the first quarter of 2016.  Direct operating expenses for the three months ended June 30, 2016 were $43 million.  Direct operating expenses increased 138% year over year, driven primarily by the inclusion of produced water handling and high rate water transfer services, as well as the expansion of Antero Midstream’s gathering and compression and fresh water delivery assets to support the production growth of Antero Resources.  General and administrative expenses were $7 million during the second quarter of 2016, an increase of 17% compared to the second quarter of 2015. Total cash and non-cash operating expenses were $84 million, including $24 million of depreciation, $7 million of equity-based compensation, and $3 million of accretion of contingent acquisition consideration.

The Board of Directors of Antero Resources Midstream Management LLC, the general partner of Antero Midstream, declared a cash distribution of $0.25 per unit ($1.00 per unit annualized) for the second quarter of 2016. The distribution represents a 32% increase compared to the prior year quarter and a 6% increase sequentially.  The distribution is Antero Midstream’s sixth consecutive quarterly distribution increase since its initial public offering in November 2014 and will be payable on August 24, 2016 to unitholders of record as of August 10, 2016.

Balance Sheet and Liquidity

As of June 30, 2016, Antero’s consolidated total debt and consolidated net debt were $4.2 billion, of which $900 million were borrowings outstanding under the Company’s and Antero Midstream’s revolving credit facilities.  Total lender commitments under these two facilities are currently $5.5 billion.  Including $708 million in letters of credit outstanding, the company had $3.9 billion in available consolidated liquidity as of June 30, 2016.  For a reconciliation of consolidated net debt to consolidated total debt, the most comparable GAAP measure, please read “Non-GAAP Financial Measures.”

Second Quarter 2016 Capital Spending

Antero’s drilling and completion costs for the three months ended June 30, 2016 were $315 million.  In addition, the Company invested $30 million for land and $1 million in other capital projects.  Antero Midstream invested $48 million for gathering and compression systems and $42 million for water infrastructure projects including $33 million on the Antero Clearwater treatment facility during the quarter.

Non-GAAP Financial Measures

Revenue excluding unrealized hedge (gains) losses as set forth in this release represents total operating revenue adjusted for unsettled hedge (gains) and losses.  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):

Adjusted net income as set forth in this release represents net income (loss), 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 is not a measure of financial performance under GAAP and should not be considered in isolation or as a substitute for net income (loss) as an indicator of financial performance.  The following table reconciles net income (loss) to adjusted net income (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.  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 consolidated total debt to consolidated net debt as used in this release (in thousands):

Adjusted EBITDAX is a non-GAAP financial measure that the Company defines as net income (loss) 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 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, 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).
