Antero Resources is an E&P company focused on developing shale gas assets in the Appalachian region, including the Marcellus and Utica shales. It has over 429,000 net acres across its core positions. Antero has a proven track record of growth, increasing its proved reserves by 44% in the first half of 2013 to over 6 trillion cubic feet equivalent. It also grew production 115% year-over-year to 458 million cubic feet equivalent per day as of the second quarter of 2013. Antero has a large inventory of undrilled locations that can support further production growth from its sizable reserves and low-cost operating model.

production including 4,300 Bbl/d of liquids constrained/shut-in waiting on pipeline, compression or processing
• Large, low risk drilling inventory – Over 4,500 horizontal drilling locations will continue to feed high growth in
existing 6.3 Tcfe(1) proved reserve base as of June 30, 2013 (assuming ethane rejection)
• Low cost leader – $1.03/Mcfe 3-year pro forma development cost calculated using 2012 J.P. Morgan methodology(2)

ethane rejection (~40% liquids exposure if assume ethane recovery in 2014 and beyond)
• Large long-term hedge position – 1,024 Bcfe hedged at $5.11/MMBtu NYMEX-equivalent(3) through 2019
• Infrastructure emphasis – Gathering, compression and processing infrastructure either in place or committed and
underway – well positioned in southern portion of Marcellus and Utica Shale plays for access to gas takeaway
• Strong liquidity to fuel low cost growth – ~$1.0 billion(4) of undrawn borrowing base capacity as of June 30, 2013

___________________________
1. Ethane rejection occurs when ethane is left in the wellhead gas stream when the gas is processed, rather than being separated out and sold as a liquid after fractionation. When ethane is left in the gas stream, the
BTU content of the residue gas at the outlet of the processing plant is higher. Producers will elect to ‘‘reject’’ ethane when the price received for the higher BTU residue gas is greater than the price received for the
ethane being sold as a liquid after fractionation. When ethane is recovered, the BTU content of the residue gas is lower, but a producer is then able to recover the value of the ethane sold as a separate NGL product.

World class asset
base with scale
 Liquids-rich Marcellus and Utica shale plays are two of the premier U.S. shale plays
 Antero has scale in both of these plays – 328,000 net acres in the Marcellus Shale
and 101,000 net acres in the Utica Shale
Large, low risk
drilling inventory
 $1.03/Mcfe 3-year development cost leader through 2012 per J.P. Morgan equity
research methodology
 $0.90/Mcfe average net development cost for 6/30/2013 3P reserves – assuming
ethane rejection
Low cost leader
 115% average Marcellus production growth from 2Q 2012 to 2Q 2013
 12% liquids by production volume today forecast to grow to ~20% by 2014 assuming
ethane rejection (~40% assuming ethane recovery)
Large long-term
hedge position
 1,024 Bcfe hedged at $5.11/MMBtu NYMEX-equivalent(1) through 2019
Rapid production
growth with liquids
exposure
 100% drilling success rate in the 208 horizontal wells in Marcellus, Utica and Upper
Devonian Shales to date
 Over 3,600 horizontal drilling locations in the Marcellus and Utica; an additional 900
horizontal drilling locations have been identified in the Upper Devonian

38. The U.S. Securities and Exchange Commission (SEC) permits oil and gas companies, in their filings with the SEC, to disclose only proved,
probable and possible reserve estimates (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 reserves included in this presentation have
been audited by Antero’s third-party engineers. Antero’s estimate of probable and possible reserves was prepared by Antero’s internal reserve
engineers, has not been reviewed by third-party engineers, and is provided in this presentation because management believes it is useful
information that is widely used by the investment community in the valuation, comparison and analysis of companies. Antero does not plan to
include probable and possible reserve estimates in its filings with the SEC.
We use certain other terms in this presentation relating to estimates of hydrocarbon volumes that the SEC’s guidelines prohibit us from
including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved, possible or probable reserves
as defined by SEC regulations and accordingly are substantially less certain and no discount or other adjustment is included in the presentation
of such numbers. 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 our 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, 2013. 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.
“Unrisked Resource” refers to Antero’s internal estimates of hydrocarbon quantities that Antero’s management believes may be potentially
discovered through exploratory drilling or recovered with additional drilling. Unrisked resource may not constitute 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. Actual
quantities that may be ultimately recovered from Antero’s interests will differ substantially. Factors affecting ultimate recovery include the
scope of our 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. Estimates of unrisked resource
may change significantly as development of Antero's resource plays provides additional data.
“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 Petroleum Engineer’s Petroleum Resource Management System or the SEC’s oil and natural gas
disclosure rules.
