APPENDIX | RESERVE GROWTH 61 Competitive Gathering and Compression Fee Structure 1 AR Pays Competitive Gathering & Compression Fees - AR’s gathering and compression fees paid to AM are below the Appalachian average based on extensive internal analysis of 19 publicly disclosed and undisclosed private midstream contracts

2 AR has Low or No MVCs with AM - No minimum volume commitments (“MVCs”) on any low pressure gathering with AM - MVCs on high pressure gathering and compression assets put in-service after the AM IPO (11/2014) - 75% to 70% MVCs on high pressure gathering and compression, respectively, when a project is requested by AR - MVC levels are determined by AR’s production forecast and capacity needs; AM may build infrastructure with capacity larger than requested for efficiency purposes that is not subject to MVCs

3 AR Receives Reliable and Timely Gathering and Compression from AM - AR has complete visibility and drives AM’s planning and in-service timing for key infrastructure projects - AR is essentially AM’s sole customer, which results in unmatched service - AR receives just-in-time customized and controlled midstream buildout - Critical to AR’s ability to execute its development plan and optimize its capital efficiency

APPENDIX | GATHERING AND COMPRESSION FEES 63 Competitive Fresh Water Fee Structure 1 AR Pays Highly Competitive Fresh Water Fees - AR pays a fixed-fee per barrel to AM for fresh water pipeline service at the well pad that is firm and is $0.50/Bbl lower cost than variable sourcing and trucking costs Peer Challenges: - Exposure to trucking cost inflation currently observed in Appalachia, driven by continued production growth and larger completions requiring more water 2 AR has Water MVCs with AM only through 2019 - AR has very manageable MVCs on fresh water of 120 Mbbl/d in both 2018 and 2019 3 AR Receives Reliable and Timely Fresh Water Service From AM - AR has never missed a scheduled completion date due to the inability to source and transport fresh water for completions through AM Peer Challenges: - Unavailability of local water sources during dry season or drought - Logistical challenges accessing pads and rural roads by truck, particularly during inclement weather 4 Sustainable Clean Water via Pipeline - Fresh water pipeline system eliminated >620,000 truck trips and 42,000 tons of CO2 emissions for AR in 2017 alone - Full-cycle water system integrated with Antero Clearwater facility to reuse the fresh water by- product of the advanced wastewaster treatment Peer Challenges: - Utilizing produced and flowback water in completions rather than fresh water increases chemical costs during completions and increases risk of negative impact on reservoir productivity

APPENDIX | FRESH WATER DELIVERY FEES 64 AR Saved ~$0.50/Bbl on Fresh Water in 2017 Antero analyzed its 2017 completions and the “avoided cost” of utilizing AM’s fresh water pipeline system vs. trucking water for completions - Antero utilized mapping and routing expertise to find optimized routes to each pad (i.e. “best case” travel routes) - Costs on a per barrel basis can vary dramatically due to hourly trucking costs (typical delays due to: staging and loading times, traffic congestion, completion shut-downs, bad weather, and challenging topography) - AR realized savings in 2017 alone totaled $0.50/Bbl or $28 million Antero 2017 Average Loading Time (Minutes) 60 Staging Time (Minutes) 120 Nicki Pad – 6 Wells Trucking Cost per Hour $90 Round Miles Minutes $/Bbl Barrels Per Truck (Bbls) 90 Trip

Please see “Antero Definitions” and “Antero Non-GAAP Measures” in the Appendix. APPENDIX | SINGLE WELL ECONOMICS 73 Antero Non-GAAP Measures

Consolidated Adjusted EBITDAX, Stand-alone E&P Adjusted EBITDAX, Consolidated Adjusted Operating Cash Flow, Stand-alone E&P Adjusted Operating Cash Flow and Free Cash Flow are financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). The non-GAAP financial measures used by the company may not be comparable to similarly titled measures utilized by other companies. These measures should not be considered in isolation or as substitutes for their nearest GAAP measures. The Stand-alone measures are presented to isolate the results of the operations of Antero apart from the performance of Antero Midstream, which is otherwise consolidated into the results of Antero. Consolidated Adjusted EBITDAX and Stand-alone E&P Adjusted EBITDAX The GAAP financial measure nearest to Consolidated Adjusted EBITDAX is net income or loss including noncontrolling interest that will be reported in Antero’s consolidated financial statements. The GAAP financial measure nearest to Stand-alone E&P 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 Consolidated Adjusted EBITDAX and Stand-alone E&P 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. Consolidated Adjusted EBITDAX is also used by the board of directors as a performance measure in determining executive compensation. Consolidated 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 Consolidated Adjusted EBITDAX and Stand-alone E&P 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, Consolidated Adjusted EBITDAX and Stand-alone E&P Adjusted EBITDAX provide no information regarding a company’s capital structure, borrowings, interest costs, capital expenditures, and working capital movement or tax position.

APPENDIX | DISCLOSURES & RECONCILIATIONS 74 Antero Non-GAAP Measures

Antero has not included a reconciliation of Consolidated Adjusted EBITDAX or Stand-alone E&P Adjusted EBITDAX to their nearest GAAP financial measures for 2018 because it cannot do so without unreasonable effort and any attempt to do so would be inherently imprecise. Antero is able to forecast the following reconciling items between Consolidated Adjusted EBITDAX and Stand-alone E&P Adjusted EBITDAX to net income from continuing operations including noncontrolling interest:

(in thousands) Consolidated Stand-alone E&P Low High Low High Interest expense $250,000 $300,000 $200,000 $220,000 Depreciation, depletion, amortization, and accretion expense 950,000 1,050,000 800,000 900,000 Impairment expense 100,000 125,000 100,000 125,000 Exploration expense 5,000 15,000 5,000 15,000

Distributions from unconsolidated affiliates 40,000 50,000 N/A N/A Distributions from limited partner interest in Antero Midstream N/A N/A 166,000 170,000

Antero has a significant portfolio of commodity derivative contracts that it does not account for using hedge accounting, and forecasting unrealized gains or losses on this portfolio is impracticable and imprecise due to the price volatility of the underlying commodities. Antero is also forecasting no impact from franchise taxes, gain or loss on early extinguishment of debt, or gain or loss on sale of assets, for 2018. For income tax expense (benefit), Antero is forecasting a 2018 effective tax rate of 18% to 19%.

APPENDIX | DISCLOSURES & RECONCILIATIONS 75 Antero Non-GAAP Measures

Consolidated Adjusted Operating Cash Flow, Stand-alone E&P Adjusted Operating Cash Flow and Free Cash Flow The GAAP financial measure nearest to Consolidated Adjusted Operating Cash Flow is cash flow from operating activities as reported in Antero’s consolidated financial statements. The GAAP financial measure nearest to Stand-alone E&P Adjusted Operating Cash Flow and Free Cash Flow is Stand-alone cash flow from operating activities that will be reported in the Parent column of Antero’s guarantor footnote to its financial statements. Management believes that Consolidated Adjusted Operating Cash Flow and Stand-alone E&P 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. Management believes that Free Cash Flow is a useful measure for assessing the company’s financial performance and measuring its ability to generate excess cash from its operations. There are significant limitations to using Consolidated Adjusted Operating Cash Flow, Stand-alone E&P Adjusted Operating Cash Flow and Free 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 E&P basis, the lack of comparability of results of operations of different companies and the different methods of calculating Consolidated Adjusted Operating Cash Flow and Stand- alone E&P Adjusted Operating Cash Flow reported by different companies. Consolidated Adjusted Operating Cash Flow and Stand- alone E&P Adjusted Operating Cash Flow do 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. Antero has not included reconciliations of Consolidated Adjusted Operating Cash Flow, Stand-alone E&P Adjusted Operating Cash Flow and Free Cash Flow to their nearest GAAP financial measures for 2018 because it would be impractical to forecast changes in current assets and liabilities. However, Antero is able to forecast the earn out payments expected from Antero Midstream associated with the water drop down transaction that occurred in 2015, each of which is a reconciling item between Stand-alone E&P Adjusted Operating Cash Flow and Free Cash Flow, as applicable, and cash flow from operating activities as reported in the Parent column of Antero’s guarantor footnote to its financial statements. Antero forecasts these items to be $125 million in each of 2019 and 2020. Additionally, Antero is able to forecast lease maintenance expenditures and Stand-alone drilling and completion capital, each of which is a reconciling item between Free Cash Flow and its most comparable GAAP financial measure. For the 2018 to 2022 period, Antero forecasts cumulative lease maintenance expenditures of $200 million and cumulative Stand-alone E&P drilling and completion capital of $8.6 billion.

APPENDIX | DISCLOSURES & RECONCILIATIONS 78 Antero Midstream Non-GAAP Measures

Non-GAAP Financial Measures and Definitions

Antero Midstream views Adjusted EBITDA as an important indicator of the Partnership’s 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 the Partnership’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.

The Partnership 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 the Partnership 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.

The Partnership defines Free Cash Flow as cash flow from operating activities before changes in working capital less capital expenditures. Management believes that Free Cash Flow is a useful indicator of the Partnership’s ability to internally fund infrastructure investments, service or incur additional debt, and assess the company’s financial performance and its ability to generate excess cash from its operations. Management believes that changes in operating assets and liabilities relate to the timing of cash receipts and disbursements and therefore may not relate to the period in which the operating activities occurred.

The Partnership defines Return on Invested Capital as net income plus interest expense divided by average total liabilities and partners’ capital, excluding current liabilities. Management believes that Return on Invested Capital is a useful indicator of the Partnership’s return on its infrastructure investments.

The Partnership defines Adjusted Operating Cash Flow as net cash provided by operating activities before changes in current assets and liabilities. See “Non-GAAP Measures” for additional detail.

APPENDIX 79 Antero Midstream Non-GAAP Measures

The GAAP financial measure nearest to Adjusted Operating Cash Flow is cash flow from operating activities as reported in Antero Midstream’s consolidated financial statements. Management believes that Adjusted Operating Cash Flow is a useful indicator of the company’s ability to internally fund its activities and to service or incur additional debt. 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. Management believes that Free Cash Flow is a useful measure for assessing the company’s financial performance and measuring its ability to generate excess cash from its operations.

There are significant limitations to using Adjusted Operating Cash Flow and Free 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, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted Operating Cash Flow reported by different companies. Adjusted Operating Cash Flow does not represent funds available for discretionary use because those funds may be required for debt service, capital expenditures, working capital, income taxes, and other commitments and obligations.

Antero Midstream has not included reconciliations of Adjusted Operating Cash Flow and Free Cash Flow to their nearest GAAP financial measures for 2018 because it would be impractical to forecast changes in current assets and liabilities. Antero Midstream is able to forecast capital expenditures, which is a reconciling item between Free Cash Flow and its most comparable GAAP financial measure. For the 2018 to 2022 period, Antero forecasts cumulative capital expenditures of $2.7 billion.

Antero Resources non-GAAP measures and definitions are included in the Antero Resources analyst day presentation, which can be found on www.anteroresources.com.

APPENDIX 80 Antero Midstream Non-GAAP Measures

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 Midstream has not included a reconciliation of Adjusted EBITDA to the nearest GAAP financial measure for 2018 because it cannot do so without unreasonable effort and any attempt to do so would be inherently imprecise. Antero Midstream is able to forecast the following reconciling items between Adjusted EBITDA and net income (in thousands):

Twelve months ended December 31, 2018 Low High Depreciation expense ...... $ 160,000 — $ 170,000 Equity based compensation expense ...... 25,000 — 35,000 Accretion of contingent acquisition consideration ...... 15,000 — 20,000 Equity in earnings of unconsolidated affiliates ...... 30,000 — 40,000 Distributions from unconsolidated affiliates...... 40,000 — 50,000

The Partnership cannot forecast interest expense due to the timing and uncertainty of debt issuances and associated interest rates. Additionally, Antero Midstream cannot reasonably forecast impairment expense as the impairment is driven by a number of factors that will be determined in the future and are beyond Antero Midstream’s control currently.

APPENDIX 82 Cautionary Note

Regarding Hydrocarbon Quantities The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserve estimates (collectively, “3P”). Antero has provided internally generated estimates for proved, probable and possible reserves in this presentation in accordance with SEC guidelines and definitions. The estimates of proved, probable and possible reserves as of December 31, 2017 included in this presentation have been audited by Antero’s third-party engineers. Unless otherwise noted, reserve estimates as of December 31, 2017 assume ethane rejection and strip pricing. Actual quantities that may be ultimately recovered from Antero’s interests may differ substantially from the estimates in this presentation. 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. In this presentation: • “3P reserves” refer to Antero’s estimated aggregate proved, probable and possible reserves as of December 31, 2016. 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. • “EUR,” or “Estimated Ultimate Recovery,” refers to Antero’s internal estimates of per well hydrocarbon quantities that may be potentially recovered from a hypothetical future well completed as a producer in the area. These quantities do not necessarily constitute or represent reserves within the meaning of the Society of Engineer’s Petroleum Resource Management System or the SEC’s oil and natural gas disclosure rules. • “Condensate” refers to gas having a heat content between 1250 BTU and 1300 BTU in the Utica Shale. • “Highly-Rich Gas/Condensate” refers to gas having a heat content between 1275 BTU and 1350 BTU in the Marcellus Shale and 1225 BTU and 1250 BTU in the Utica Shale. • “Highly-Rich Gas” refers to gas having a heat content between 1200 BTU and 1275 BTU in the Marcellus Shale and 1200 BTU and 1225 BTU in the Utica Shale. • “Rich Gas” refers to gas having a heat content of between 1100 BTU and 1200 BTU. • “Dry Gas” refers to gas containing insufficient quantities of hydrocarbons heavier than methane to allow their commercial extraction or to require their removal in order to render the gas suitable for fuel use.
