Executive Summary As Antero Resources (“AR”) continues to evaluate a potential simplification transaction between Antero Midstream GP LP (“AMGP”) and Antero Midstream Partners (“AM”), J.P. Morgan has prepared these discussion materials to address the following topics: consideration in a transaction, the metrics as compared to peers leverage (>3.0x Debt / 2018E spreads and rating agency views equity investor views and strategic credit documents including the RP 2 After a multi-month, detailed review of all potential alternatives, J.P. Morgan continues to believe that the currently contemplated transaction between AMGP and AM is the most attractive structural alternative for AR  In evaluating potential levels of cash following should be considered:  Pro forma AM / AMGP leverage  Potential implications of higher EBITDA) at AM / AMGP on credit  Implications of higher leverage on financial flexibility  Considerations raised by AM’s basket in AM’s bond indenture  Transaction results in a best-in-class midstream C-Corp with traditional governance, peerless distribution growth and a self-sustaining balance sheet  We would expect the pro forma entity to trade at a significant premium to AMGP’s current share price  AR owning pro forma AMGP C-Corp shares vs. AM LP units materially enhances liquidity and monetization ability  C-Corp structure provides larger float, trading volume, access to institutional capital, and an improved future source of liquidity for AR  Precedent E&P monetizations of midstream LP interests have been mixed and often require a significant discount (e.g., Devon and EnLink)  AR improves its position at AM across a range of criteria, including governance, valuation, trading liquidity and ability to monetize  Eliminates concerns regarding incentives associated with IDRs and Series B units held by AMGP  Places midstream assets in C-Corp structure with traditional governance favored by investors  As the largest owner of pro forma AMGP (without IDRs and Series B units), AR can benefit from acquisitions of integrated upstream and midstream assets  The transaction also provides an efficient way to raise cash sufficient to reduce leverage and / or execute a prudent share repurchase program at AR  The transaction addresses a majority of the key issues raised by AR shareholders Credit and leverage considerations of pro forma AMGP / AM Trading and valuation of pro forma AMGP / AM Benefits to AR of a simplification transaction

General Benefits of an AMGP / AM Merger to AR 3 A Merger of AMGP and AM Provides More Benefits to AR Than Any Other Proposed Transaction J.P. Morgan believes that an acquisition of AM by AMGP is attractive to AR for the following reasons:  Significantly addresses “misalignment” concerns regarding incentives associated with IDRs and Series B units held by AMGP and creates C-Corp structure with traditional governance  AR receiving a premium for AM units in part for cash; sales of AM units today would carry a substantial discount  C-Corp structure provides larger float, liquidity, access to institutional capital, and an improved future source of liquidity for AR  Pro forma AM / AMGP would be a highly-attractive midstream C-Corp with differentiated growth, coverage, leverage and yield profile  AM receives up-front premium and accretion to long-term distributions  Tax shelter provided by step-up enhances AMGP DCF  Analysis indicates AMGP should trade at a significant premium to its current share price  AR goes from having limited voting rights at AM to being the largest AMGP stockholder with proportionate voting rights  Lowers AM cost of equity capital due to elimination of IDRs and Series B units  Generally consistent with expectations of third party commentators  Potential for modest cash component facilitates AR share repurchases consistent with recent peer actions and investor preferences

Credit Considerations of Transaction a Sizeable Cash Component in a Potential AMGP / AM 15  AM’s credit agreement does not allow for any restricted payments outside of regular distributions to unitholders  Any cash consideration as part of a simplification transaction will require AM to seek a 50.1% amendment from RCF lenders to allow for the restricted payment  Given current drawing under the RCF, AM has been contemplating exercising the incremental with the credit facility and increasing commitments from $1.5bn to $2.0bn in conjunction with any simplification  The RCF lenders are all private side bank relationship lenders who have seen the AM’s projections over time and also heard their communicated financial policy  The increased leverage profile of AMGP PF could make the execution of the amendment and the $500mm upsize more challenging Ramifications for Credit Facility  AM trading levels could be negatively impacted as a result of incremental leverage and investor surprise with the Company’s breach of its financial policy and the flexibility of the existing indenture  Antero currently estimates their restricted payment capacity in AM’s high yield indenture to be ~$700 - $750 million  Restricted payment calculations are notoriously challenging for investors to calculate without direct input from the Company  Meaningful usage of AM’s large restricted payment capacity will likely be surprising to investors as most high yield issuers, particularly public companies, rarely push the envelope of their restricted payment capacity  Additionally, MLPs rarely make any meaningful restricted payments outside of their regular distribution to unitholders  While impossible to perfectly predict, J.P. Morgan believes that with the contemplated amount of cash consideration, AM’s existing high yield notes could trade off by ~100bps and expect a similar impact to any near-term new issues rates used to term out revolving credit facility borrowings Ramifications for High Yield  J.P. Morgan understands that the cash consideration of any AMGP / AM transaction will be structured to avoid requiring AM bondholder consent  Since its inaugural bond offering, AM has communicated a financial policy to bondholders of leverage between 2.0x – 2.5x, with the potential to flex up to ~3.0x in conjunction with accretive acquisitions  With a cash component at / near $700 million, AMGP pro forma leverage will exceed 3.0x, a departure from AM’s corporate policy  Both Antero and Antero Midstream have been able to achieve best in class pricing in the high yield market over time and are now considered a “darling” of the high yield space with a trajectory to investment grade  The current AM high yield trading levels of $100.75 / 5.17% reflect not only AM’s credit profile but also the trust that AR and AM management have built with investors through years of delivering strong financial and operational results Overview

Conclusion

Summary Takeaways 17 A Merger of AMGP and AM Provides More Benefits to AR Than Any Other Proposed Transaction Based on its detailed analysis of the potential structural alternatives previously reviewed with the AR Special Committee and the Board, Antero management and its advisors continue to believe that an acquisition of AM by AMGP is the most attractive structural alternative for AR’s shareholders  Financially viable to equity holders of AR, AMGP and AM  Best addresses AR shareholder concerns regarding mis-alignment of incentives  Pro forma AM / AMGP would be highly-attractive midstream C-Corp with differentiated growth, coverage, leverage and yield profile  AM receives up-front premium and accretion to long-term distributions  Tax shelter provided by step-up enhances AMGP DCF  Analysis indicates AMGP should hold value and even improve  C-Corp structure provides larger float, liquidity, access to institutional capital, and an improved future source of liquidity for AR as exampled by ONEOK and Macquarie Infrastructure  At pro forma leverage of 3.0x or lower, there is little risk of a credit downgrade at AMGP pro forma

Wall Street Perspectives “We view a consolidation of the midstream complex as the most likely outcome of this review” “the combined midstream asset base could see a significant rerate with NAV of inventory blowdown >$12.5B vs. current combined equity value of ~$8.5B.” “Though two scenarios are explored, relative valuation gap between AM and AMGP leaves a GP buy-in of the LP as the more probable outcome.” - TPH - TPH - TPH “We believe that the focus remains on the potential merger of Antero Midstream GP and conversion from an MLP structure to a corporation. We would view a simplified proforma entity favourably.” “[Post-transaction, the pro-forma entity] would retain a far and away best in class dividend / share growth outlook with conservative coverage and a very conservative leverage ratio for the foreseeable future.” “we see AM+AMGP potentially trading at 11.4x 2019e EBITDA, a level we believe could be quite attractive relative to an estimated 2019-2021 EBITDA CAGR of 22%.” - TD Securities - Raymond James - Morgan Stanley 20 Pro forma Valuation Midstream Simplification
