events or developments that Antero Resources Corporation and its subsidiaries (collectively, the “Company” or “Antero”) expects, believes or
anticipates will or may occur in the future are forward-looking statements. The words “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,”
“project,” “foresee,” “should,” “would,” “could,” or other similar expressions are intended to identify forward-looking statements. However, the
absence of these words does not mean that the statements are not forward-looking. Without limiting the generality of the foregoing, forwardlooking statements contained in this presentation specifically include estimates of the Company’s reserves, expectations of plans, strategies,
objectives and anticipated financial and operating results of the Company, including as to the Company’s drilling program, production, hedging
activities, capital expenditure levels and other guidance included in this presentation. These statements are based on certain assumptions made
by the Company based on management’s experience and perception of historical trends, current conditions, anticipated future developments and
other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are
beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking
statements. These include the factors discussed or referenced in the Company’s Registration Statement on Form S-1 (File No. 333 – 189284)
(the “Registration Statement”) with the U.S. Securities and Exchange Commission (the “SEC”) and in the Company’s subsequent filings with the
SEC.
The Company cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to
predict and many of which are beyond our control, incident to the exploration for and development, production, gathering and sale of natural gas
and oil. These risks include, but are not limited to, commodity price volatility, inflation, lack of availability of drilling and production equipment and
services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating natural gas and oil
reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures, and the other risks
described under the heading “Risk Factors” in the Registration Statement and in the Company’s subsequent filings with the SEC.
Any forward-looking statement speaks only as of the date on which such statement is made and the Company undertakes no obligation to correct
or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.

14. MARCELLUS – SIMPLE STRUCTURE
 Several regional anticlines in core area
− Predictable “layer cake” geology
− No faults at Marcellus level
• Over 1.5 million feet (285 miles)
drilled horizontally without
crossing a fault
− 3-D seismic not required to guide
horizontal wells
 Regional East-West seismic line shows
gentle structure at Marcellus level
 Allegheny Front and complex structure
located many miles east of core area

15. ANTERO’S MARCELLUS SHALE TYPE CURVE SUPPORT
 Antero has four years of production data, from 217 operated horizontal wells, to support its 1.5 Bcf / 1,000’ of lateral type curve
– DeGolyer & MacNaughton (D&M), Antero’s third-party reserve auditor, fully supports this type curve
 Average 24-hour wellhead peak rate (IP) of 14.1 MMcf/d; 14.9 MMcfe/d processed assuming ethane rejection
 Lack of faulting and contiguous acreage position allows for drilling of long laterals
− Drives down costs per 1,000’ of lateral resulting in best-in-class development costs

17. ENHANCING MARCELLUS RECOVERIES
– SHORTER STAGE LENGTHS (“SSL”)
 Since June 2013 Antero has
implemented shorter stage lengths
(SSL) in the Marcellus Shale
– 29 SSL wells completed
– 22 SSL wells have at least 30 days
of production history
– 150’ to 225’ vs. 350’ stages
previously
 The 30-day rate for Antero’s first 22
unconstrained SSL wells has
averaged 10.0 MMcf/d or 31% higher
than the average Antero non-SSL 30day rate of 7.6 MMcf/d
– This rate improvement has been
maintained over longer production
periods with the 120-day SSL well
rate for 10 wells 27% higher than
for non-SSL wells
– Other Marcellus southwestern core
operators have announced 20% to
30% improvement in IPs and EURs
 Estimated 12% increase in well costs
for SSL as compared to non-SSL
wells

1. Ethane rejection occurs when ethane is left in the wellhead gas stream as 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.

30. MARCELLUS SHALE RICH GAS –
LIQUIDS AND PROCESSING UPGRADE
 Marcellus Shale rich gas and highly-rich gas acreage provides a significant advantage in well economics – assuming $4.25/MMBtu NYMEX,
$90.00/Bbl WTI and current spot NGL pricing correlation
 Upgrade analysis demonstrates that ethane recovery is not economic at current ethane price

33. 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 June 30, 2013 included in this
presentation have been audited by Antero’s third-party engineers. Unless otherwise noted, reserve estimates are as of June 30, 2013, assuming
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, 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.
 “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.
 “Highly-rich/condensate” refers to gas having a heat content between 1275 BTU and 1350 BTU in the Marcellus Shale and 1250 BTU and 1300
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 1250 BTU in
the Utica Shale.
 “Rich gas” refers to gas having a heat content of between 1100 BTU to 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.
