ANTERO MIDSTREAM – A GROWTH FOCUSED MLP

2

• AM sponsor is the most active operator in Appalachia• Highest recycle ratio and low F&D cost supports sponsor production growth expectations• Sponsor maintains strong liquidity and significant hedging position• Highly incentivized to maximize value of AM to support AR growth

• Midstream assets located in lowest cost per Mcfe rich gas plays in North America• ~80% of midstream “footprint” is associated with rich gas production• Substantial AR and third-party future infrastructure required• Gathering and compression provide core asset portfolio with additional option to

expand into freshwater distribution and regional pipelines

• Pure play, fee-based midstream MLP with top tier growth rate• Cash flows are supported by 20-year, fee-based agreements with AR• “Best in class” anchor tenant with 90% expected net production growth in 2014 and

45-50% growth in both 2015 and 2016• Growth not dependent on drop-downs, 3rd party business or acquisitions for growth

• Consolidated Marcellus and Utica rich gas acreage dedications• Multiple gathering and compression, processing, pipeline and other expansion

opportunities• Option to acquire AR Fresh Water Distribution system

• Antero Midstream MLP had no leverage at IPO closing plus $250 million cash • $1 billion of undrawn borrowing capacity commitments at IPO• Good high yield access with “Ba3/BB” rated parent (corporate ratings)• Structured to pursue organic growth opportunities

ANTERO MIDSTREAM ASSETS – RICH GAS MARCELLUS

5

• Provides Marcellus gathering and compression services − Liquids-rich gas is delivered to MWE’s Sherwood

Complex for processing• Significant growth projected over the next twelve

months as set out below:

• Antero sold the Harrison County portion of its gathering system to a 3rd party midstream company in 2012, which is now recognized as the 3rd Party Gathering and Compression Dedication area

• Development upside as AR continues to drill, step-out and add acreage

Marcellus Gathering & Compression

Note: Antero acreage position reflects tax districts in which greater than 3,000 net acres are owned.

• Provides Utica natural gas and condensate gathering services− Liquids-rich gas delivered into MWE’s Seneca

Complex for processing− Condensate delivered to centralized stabilization

and truck loading facilities• Significant growth projected over the next twelve

months as set out below:

ORGANIC GROWTH STRATEGY: “BUILD VS. BUY”

8

• Organic growth strategy provides attractive returns and project economics, while avoiding the competitive acquisition market

• Industry leading organic growth story

– ~$875 million in estimated capital spent through 6/30/2014

– $587 million in additional growth capital forecast for the twelve-month period ending 9/30/15 (excludes $15 million of maintenance capital)

Note: Precedent data per IHS Herold’s research and public filings.1. Antero organic multiple calculated as estimated gathering and compression capital expended through Q2 2014 divided by NTM 9/30/15 projected gathering and compression EBITDA.2. Selected gathering and compression drop down acquisitions since 1/1/2011. Drop down multiples are based on NTM EBITDA. Source: Barclays.

MAINTENANCE CAPITAL METHODOLOGY

• Maintenance Capital Calculation Methodology– Estimate the number of new well connections needed during the forecast period in order to offset the natural

production decline and maintain the average throughput volume on our system over the LTM period

– (1) Compare this number of well connections to the total number of well connections estimated to be made during such period and

– (2) Designate an equal percentage of our estimated gathering capital expenditures as maintenance capital expenditures

28Source: Antero Midstream S-1; maintenance capital calculation per management estimates.

Maintenance capital expenditures are cash expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) made to maintain, over the long term, our operating capacity or revenue

• Illustrative Example

CAUTIONARY NOTE

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, which have been audited by Antero’s third-party engineers. Unless otherwise noted, reserve estimates as of June 30, 2014 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 June 30, 2014. 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 bepotentially 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 Petroleum 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.
